    Method for manufacturing a building construction from curable construction material, inflatable body, device and building construction therefor
    The invention relates to a method for manufacturing a building construction from curable construction material. The invention also relates to an inflatable body intended for the method, a device for applying a curable construction material and a building construction of curable construction material obtained according to the method.
    A method for manufacturing a building construction from curable construction material is known, for example, from WO 2007/061299 from the same applicant. WO 2007/061299, incorporated herein by reference, describes a method for manufacturing a building structure by means of an inflatable body. An important advantage that can be achieved with this is that curved building surfaces can be produced efficiently and efficiently. A drawback is that the structural freedom and the size of the building structures thus to be manufactured is limited. All of the further embodiments of the present invention to be described can be carried out separately or in combination with the techniques described in WO 2007/061299.
    The present invention has for its object to provide a method for manufacturing a building construction from curable construction material, as well as the associated means, with which a greater structural freedom and size of the building structures to be manufactured can be obtained.
    To this end, the invention comprises a method for manufacturing a building construction from curable construction material, comprising the processing steps of arranging and positioning an inflatable body on at least two frame parts, in such a way that a pre-designed shape is thereby obtained, the inflatable body, applying curable construction material to at least a portion of the inflated inflatable body, and allowing the construction material applied to the inflated inflatable body to harden, wherein the inflatable body - at least over a part of its length by means of a frame part is positioned at a distance from a surface.
    The inflatable body can thus be kept at a distance from the ground by means of a frame part. As a result, for example, the volume of the inflatable body can remain limited in the manufacture of building structures which comprise curved surfaces situated at a relatively large distance from the substrate. After all, the total height between such a curved building surface to be manufactured at a great distance from the substrate no longer only has to be bridged by the inflatable body. The presence of a frame part also increases the controllability of the position of the inflatable body because it will be held in place by the frame part. The frame part can for instance be mobile so that the inflatable body when it is not used for the manufacture of a building construction can easily be moved. The tension wires can for instance be cables, tires, chains or combinations thereof, optionally in combination with rigid elements. The curable construction material can be, for example, concrete, a composite, a resin or another curable construction material.
    At least a portion of the anchoring elements are provided on the frame member for anchoring the inflatable body directly to a frame member. The inflatable body can thus easily be positioned close to the frame part and the anchoring of the tensioning wires is relatively simple.
    After the curable structural material has at least partially cured, the inflatable body can be removed after the inflatable body has been brought into an at least partially deflated state (state in which the one-sided overpressure on the inflatable body has been reduced) - and at least partially cured. remaining construction material in the applied form. When the curable construction material is cured, it forms a self-supporting construction and support by means of a frame part and inflatable body is no longer necessary. It is noted here that reinforcement elements can also be included in the curable construction material, such as, for example, ribs, cables, so as to be able to form an (even better) self-supporting building construction.
    Multiple frame parts can be coupled and stabilizing elements can be arranged between the coupled frame parts, such that the tensile forces exerted on the frame parts by the inflatable body are eliminated. By coupling several frame parts - and possibly also several inflatable bodies - the device for applying a curable construction material can be enlarged. Multiple inflatable bodies of considerable size can hereby also extend over several frame parts and be positioned and / or supported by several frame parts. Thus, the freedom of form and the possible size of the building construction to be manufactured is evidently increased.
    At least one of the coupled frame parts can be moved to a changed location near or adjacent to the already applied material. Here again, an inflatable body can be positioned at least partially between the frame parts. When, for example, the curable construction material is sufficiently cured, it forms a self-supporting building construction and support by means of an inflatable body, tension wires and possibly a frame part is no longer necessary. The frame part or an assembly of a plurality of frame parts can then, for example, be removed and moved to provide and / or support another part of the building construction - for example, a connecting part. When, for example, a building construction of great length is made, an assembly of three frame parts can be used. When the curable construction material is cured at the height of a front frame part, this front frame part can be disconnected from the tension wires and possibly also the other frame parts. The uncoupled frame part can then be coupled on a different side with the remaining frame parts, so that a new part of curable construction material can be applied to the inflatable body of that newly coupled frame part. This can be repeated so that building structures of a very large size can be manufactured with the method according to the invention. Thus, with a limited number of frame parts and one or a limited number of inflatable bodies, building construction of a very large size (for example a large length) such as tunnels can be manufactured, and the available frame parts and inflatable bodies are moreover effectively used.
    Prior to applying curable construction material, the shape of the inflatable body - whether or not during its inflation - can be achieved by at least one additional design element engaging the inflatable body, such as, for example, a cable, wherein the design element exerts a force on the inflatable body. In order to improve the possibilities of shaping the mold and thus the building construction to be manufactured, as well as to improve the controllability of the deformation of the inflatable body, a plurality of shaping elements can also engage on the same point of engagement and / or the shaping element can over a greater length on the inflatable engage the body. The shaping elements can force the inflatable body into a pre-designed shape, and thus shape the inflatable body into a mold for at least a portion of the building structure to be placed. The shaping element, for example, engages on the inside of the inflatable body, and exerts a tensile force on the inside of the inflatable body. Another possibility is, for example, to use shaping elements that are encapsulated in the construction material when applying the curable construction material (in line with a "lost mold" casting technique).
    In a specific embodiment, the shaping element can exert a force, such as a tensile force, on at least two separate lines on the inside of the inflatable body. The exertion of a force on at least two lines has the advantage that uncontrollable and undesired point-shaped deformation of the inflatable body can be prevented by the deforming element and a more controllable (curved) crimp-shaped deformation of the inflatable body can be achieved. A deformation element as such can also engage the inflatable body over a greater length or over a larger surface.
    A supporting structure can also be arranged near one or more frame parts for supporting a feed device for curable construction material. Such a support structure can be used to apply the curable construction material to the inflatable body and can ensure that the inflatable body is accessible to apply the construction material. For this purpose, for example, a spraying device for the curable construction material can be moved along the support structure.
    In yet another alternative embodiment, the position of at least a part of the surface of the inflatable body can be determined prior to the application of the curable construction material. The position of the inflatable body can be scanned, for example, by moving a measuring device along a frame part or along a supporting structure, and on the basis of a scan thus obtained, the positioning of the spraying device relative to the supporting structure can be adjusted. The adjustment can be done automatically or possibly also be influenced manually. The speed of movement, the method of spraying and the spraying rate can also be controlled - automatically or otherwise - in order to check the application of the construction material.
    The invention also relates to an inflatable body, apparently intended for a method as described above, wherein a shaping element, such as a cable, is arranged on the inside of the inflatable body. The shaping element can engage the inflatable body over a greater length, for example a line piece. The shaping element can for instance be provided with an intermediary between the skin of the inflatable body and the cable. The force that it exerts on the inflatable body thereby engages over a greater length and can cause a crease-like deformation. The shaping element can, for example, engage the inflatable body through a weld.
    The invention also relates to a device for applying a curable construction material, comprising an assembly of frame parts, anchoring elements and at least one positioned inflatable body, and a spray device of curable construction material, wherein the spray device comprises a support structure along which the spray device is displaceable for applying curable construction material to a surface defined by the inflatable body.
    The device can also comprise a scanning device for determining the position of at least a part of a surface defined by the inflatable body.
    The scanning device can, for example, determine the distance from the top of the support structure to the top of the inflatable body, and adjust the height of the spraying device relative to the support structure on the basis of the position measured by the scanning device. Such devices are suitable for carrying out a method according to the present invention and thus also the advantages listed therein can be realized.
    The invention also relates to a building construction of curable construction material obtained with the method according to the present invention.
    The invention will now be elucidated with reference to the non-limitative exemplary embodiment shown in the following figures. Herein: - figure IA shows a device for applying structural material in a cross section; figure 1B shows the device as shown in figure 1B in a side view; figure 2A shows a caterpillar arch, in cross section; figure 2B a caterpillar arch, in longitudinal section; figure 3A attachment of shaping elements according to the prior art; and - figure 3B fixation of shaping elements according to the invention.
    Figure 1A shows the cross-section of a device (1) for applying a curable construction material (2) which, as shown here, consists of an assembly of three frame parts 3, 3 ', 3 ”, a plurality of anchoring elements (4), frame couplings (5 , and inflatable bodies (6, 6 '). Also, a support structure (7) arranged above the inflatable bodies (6, 6') with a spraying device (8) for the curable construction material (2) is shown. The spraying device (8) is displaceable along the supporting structure (7) for spraying therewith on a curable construction material (2) determined by the inflatable bodies (6, 6 '). The distance between the spraying device (8) and the inflatable bodies (6, 6 ') can be adjusted, desirably in a direction (9) substantially perpendicular to the direction of movement of the spraying device (8).
    Figure 1B shows, according to a side view, a device (10) for applying a curable construction material according to Figure 1, comprising a support structure (11) for a spraying device (12). The spraying device describes an arc shape in the direction B-B, wherein several arc shapes are described in the other direction A-A, whereby a caterpillar arch as shown in Fig. 2A can be made.
    When building, for example, an elongated building such as a stable or a concrete tunnel, an inflatable body (6, 6 ") is positioned between the anchoring elements (4) and the inflatable body (6, 6") is inflated. Then, curable construction material (2) is applied to at least a portion of the inflatable body (6, 6 "), and the construction material (2) applied to the inflatable body (6, 6") is allowed to cure. The inflatable body is positioned at least over a part of its length by means of a frame part (3, 3 ", 3") at a distance from a surface.
    Figure 2A shows a caterpillar arch (20), obtainable via a method according to the present invention. Figure 2B shows a section A-A from Figure 2A. The arc shapes from A-A transfer the forces to arc B-B, whereby the caterpillar arch (20) receives extra strength. The arc shapes can be obtained by spraying curable construction material from a spraying device onto an inflatable body (consisting of two inflatable bodies 6, 6 ") supported by coupled frame parts (3, 3", 3 ").
    Figure 3A shows the attachment of shaping element from the prior art, in which eyes (30, 31) are attached to the inside of an inflatable body (32). The left eye (30) is provided with a cord (33) without force, the right eye (31) is provided with a cord (34) with a force so that it is tight and exerts a force on the eye (31). This force results in a point load on the eye (31) and thus on the inflatable body, whereby curable construction material (35) is applied in the point shape determined by the force.
    Figure 3B shows an embodiment of the attachment of shaping element (41, 42) according to the present invention, wherein shaping element (41, 42), such as cables, are arranged on the inside of an inflatable body (40), which via an intermediary of the same material such as that of the inflatable body are adhered to the body over a line segment (43). The strips (41,42) are for example provided with an eye (44,45). The left eye (44) has a cable (46) without force, the right eye (45) has a cable (47) with force. The force is distributed by the strip (41, 42) over two line segments (43) so that a uniform path-shaped deformation (48) can occur. Several design elements can engage per line section (43). The deformation elements can for instance be provided on the inflatable body by means of weld seams.
