Description

Technical Field

[0001] The present invention relates to a construction method, in particular to a construction method for a building and a building formed by the construction method. Background Art

[0002] Generally speaking, reinforced concrete structure (RC) refers to a building form that uses steel bars and concrete as materials, that is, after a plurality of transverse bars and a plurality of longitudinal bars are tied together, formwork is set around the plurality of transverse bars and the plurality of longitudinal bars, and then a concrete slurry is poured between the formworks. After the concrete slurry hardens to form a concrete block, the concrete block can cover the plurality of transverse bars and the plurality of longitudinal bars, and further can form a wall, floor or roof and other structures.

[0003] For example, a wall formed by reinforced concrete is a main load-bearing and earthquake-resistant structure. However, when the reinforced concrete structure is subjected to excessive external force impact, it cannot absorb the energy generated by the impact, which may cause the concrete block to break, or even cause the displacement or deformation of the steel bars after being subjected to force. In view of this, the existing construction method of buildings still needs to be improved. Summary of the invention

[0004] To solve the above problems, an object of the present invention is to provide a construction method for a building, so as to obtain a building capable of absorbing impact energy.

[0005] Another object of the present invention is to provide a building formed by the above construction method, which has better structural strength.

[0006] The directions or their approximate terms described throughout the present invention, such as "front", "rear", "left", "right", "up (top)", "down (bottom)", "inside", "outside", "side", etc., are mainly with reference to the directions of the accompanying drawings. Each direction or its approximate terms are only used to assist in the explanation and understanding of the embodiments of the present invention, and are not used to limit the present invention.

[0007] The elements and components described throughout the present invention use the quantifiers "a" or "an" for convenience only and to provide a general meaning of the scope of the present invention; they should be interpreted in the present invention as including one or at least one, and a single concept also includes plural cases, unless it is obvious that it means otherwise.

[0008] The similar terms such as "combination", "assembly" or "assembly" described in the present invention mainly include the connection that can be separated without damaging the components, or the connection that makes the components inseparable. Those skilled in the art can choose according to the materials of the components to be connected or the assembly requirements.

[0009] The construction method of the building of the present invention comprises: providing at least one metal mesh having at least one convex portion formed by bending toward a surface; combining at least one metal mesh and at least one steel mesh to form a support group, each of the steel meshes comprising a plurality of transverse bars and a plurality of longitudinal bars respectively intersecting the plurality of transverse bars; placing the support group at a predetermined position; and pouring a concrete slurry, so that after the concrete slurry hardens, a concrete block is formed to bury the support group.

[0010] Accordingly, the construction method of the building of the present invention can absorb the energy of the impact when the building is impacted by an external force by at least one protrusion of the metal mesh buried in the concrete block, thereby preventing the concrete block from being damaged by the external force impact, thereby achieving the effect of improving the structural strength of the building.

[0011] In the construction method of the building of the present invention, the support group may include a metal mesh and two steel meshes, and the two steel meshes respectively press against two opposite surfaces of the metal mesh, so as to further improve the structural strength of the building.

[0012] In the construction method of the building of the present invention, the support group may include two metal meshes and a steel mesh, and the two metal meshes respectively press against two opposite surfaces of the steel mesh. In this way, the convex parts of the two metal meshes can be used to absorb the energy of the impact, which can further improve the structural strength of the building.

[0013] In the construction method of the building of the present invention, the metal mesh can be a metal braided mesh formed by winding a plurality of metal wires, and the metal braided mesh is bent to form at least one protrusion after winding. In this way, the metal braided mesh is formed by winding a plurality of metal wires, and when the concrete slurry is poured, the concrete slurry can penetrate into the gaps between the plurality of metal wires, thereby improving the bonding strength between the hardened concrete block and the metal mesh.

[0014] In the construction method of the building of the present invention, the metal mesh can be a spot-welded metal mesh, which includes a plurality of transverse metal wires and a plurality of longitudinal metal wires intersecting each other, the intersections of the plurality of transverse metal wires and the plurality of longitudinal metal wires are welded together, and after the plurality of transverse metal wires and the plurality of longitudinal metal wires are welded together, they are bent to form at least one convex portion. In this way, the spot-welded metal mesh has a structural strength superior to that of a woven metal mesh, and the effect of increasing the structural strength of the building can be achieved.

[0015] In the construction method of the building of the present invention, the steel mesh can be a spot-welded steel mesh. In this way, since the spot-welded steel mesh has better shear strength and can avoid the complicated processes of binding and welding at the construction site, the structural strength of the building can be increased and the construction convenience of the on-site construction can be improved.

[0016] In the construction method of the building of the present invention, the metal mesh can have a plurality of convex parts, so that a concave part is formed between two adjacent convex parts. In this way, no matter which surface of the metal mesh faces the direction of the external force impact, it can be used to absorb the energy of the external force impact, and has no specific directionality at the construction site, so the construction convenience of the on-site construction can be improved; and because the metal mesh can absorb the energy of the external force impact from different directions, the structural strength of the building can also be increased.

[0017] In the construction method of the building of the present invention, along a first direction, the plurality of protrusions and the plurality of recesses can present an alternating and repeated wave shape, so that energy from the outside can be effectively absorbed.

[0018] In the construction method of the building of the present invention, along a second direction perpendicular to the first direction, between a plurality of the convex parts forming a group and arranged in a row and a plurality of the convex parts forming another group and arranged in a row, there are a plurality of concave parts forming a group and arranged in a row, and the plurality of concave parts forming a group and arranged in a row together form a receiving groove, and at least one longitudinal bar of the steel mesh can be received in the receiving groove along the second direction. In this way, by receiving a plurality of the longitudinal bars in the receiving groove, the thickness of the support group can be reduced, and the thickness of the building can be correspondingly reduced.

[0019] In the construction method of the building of the present invention, at least one transverse reinforcement of the steel mesh is arranged along the first direction, and can be located between two adjacent protrusions arranged along the second direction, and between two adjacent recesses arranged along the second direction, so that the thickness of the support group can be further reduced, and the thickness of the building can be reduced for hard ground.

[0020] The building of the present invention is made by the construction method as described above, wherein the building comprises a concrete block, at least one metal mesh and at least one steel mesh embedded in the concrete block, and at least one of the metal meshes comprises at least one convex portion formed by bending.

[0021] Accordingly, the building of the present invention can absorb the energy of the impact when the building is impacted by an external force through at least one protrusion of the metal mesh buried in the concrete block, thereby preventing the concrete block from being damaged by the external force impact, thereby improving the structural strength of the building and achieving the effect of improving the safety of people in the building.

[0053] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the attached drawings; in addition, the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0054] Please refer to Figure 1 , which is a flow chart of a construction method of a building according to an embodiment of the present invention, comprising: a support group forming step S1, a positioning step S2 and a casting step S3.

[0055] In detail, Figure 2 As shown, in the support group forming step S1, the staff can combine a metal mesh 1 and a steel mesh 2 to form a support group S. The metal mesh 1 and the steel mesh 2 can be tied to form the support group S (such as Figure 3 As shown, the metal mesh 1 and the steel mesh 2 are tied together with a binding member C); alternatively, the metal mesh 1 and the steel mesh 2 can also be welded to form the support group S, which can improve the construction convenience of forming the support group S and also improve the structural strength of the support group S.

[0056] It is worth noting that the metal mesh 1 has a first surface 1a and a second surface 1b opposite to each other, and the metal mesh 1 has at least one protrusion 11, and at least one of the protrusions 11 is formed in a bent manner toward the first surface 1a. For example, the metal mesh 1 can be a metal woven mesh formed by winding a plurality of metal wires W, and the metal woven mesh is bent to form at least one of the protrusions 11 after winding. For example, it can be disclosed in Taiwan Patent Application No. 112127781 (China Patent Application No. 202310918234.3). This is only an example. The technicians in the field of the present invention can still select any metal mesh 1 according to the needs to form the support group together with the steel mesh 2, and there is no limitation here.

[0057] Please refer to Figure 2 , Figure 3 In this embodiment, the metal mesh 1 may have a plurality of convex portions 11, and a concave portion 12 may be formed between two adjacent convex portions. Furthermore, the plurality of convex portions 11 and the plurality of concave portions 12 present an alternating and repeated wave shape, so that energy from the outside can be effectively absorbed.

[0058] The steel mesh 2 may be made of Figure 2 , Figure 3 The multiple transverse bars 21 and the multiple longitudinal bars 22 shown are formed by binding or welding, or the staff can choose a spot welded wire mesh as the reinforcement mesh 2. The spot welded wire mesh refers to a mesh formed by arranging multiple cold-rolled steel wires in a longitudinal and transverse manner and welding their intersections. Due to the use of cold-rolled steel wires combined with welding, the spot welded wire mesh has better shear strength. The spot welded wire mesh can be used to avoid the complicated processes of binding and welding at the construction site, and can also improve the convenience of on-site construction.

[0059] like Figure 3As shown, in the positioning step S2, the staff can place the support group S at a predetermined position, and according to the needs, set the template T around the support group S. Taking the building as an external wall as an example, the support group S can be placed at a predetermined position of the external wall, so that at least one convex portion 11 of the metal mesh 1 faces outward, and templates T are set on the inside and outside of the support group S, so that the external wall finally obtained can absorb the energy of the impact through at least one convex portion 11 when it is impacted from the outside. The technicians in the field of the present invention can also choose to make at least one convex portion 11 of the metal mesh 1 face inward according to the needs, so that the external wall can absorb the energy of the impact from the inside, and there is no limitation here. In addition, whether the support group S faces outward with the metal mesh 1 or the steel mesh 2, as long as the setting position of at least one convex portion 11 is ensured, the above-mentioned effect of absorbing the energy of the impact can be achieved, which is understandable to the technicians in the field of the present invention and will not be repeated here.

[0060] Then, Figure 3 , Figure 4 As shown, in the casting step S3, the staff can cast a concrete slurry between the templates T, so that the concrete slurry hardens to form a concrete block 3 that can cover the support group S, that is, the construction of the building is completed. At this time, in this embodiment, since the metal mesh 1 used is a metal woven mesh formed by winding a plurality of metal wires W, when the concrete slurry is cast, the concrete slurry can penetrate into the gaps G between the plurality of metal wires W, thereby improving the bonding strength between the hardened concrete block 3 and the metal mesh 1.

[0061] In the present embodiment, since the metal mesh 1 used includes a plurality of convex portions 11 and a plurality of concave portions 12 in an alternating and repeated wavy shape, regardless of whether the metal mesh 1 faces outward with the first surface 1a or the second surface 1b, the plurality of convex portions 11 (convex toward the first surface 1a) or the plurality of concave portions 12 (concave toward the first surface 1a, and therefore correspondingly convex toward the second surface 1b) can be used to absorb the energy generated by external force impact. Therefore, when the staff performs the positioning step S2, there is no need to limit which surface must face outward, thereby improving the convenience of on-site construction. Moreover, since the plurality of convex portions 11 and the plurality of concave portions 12 can be used to absorb the energy generated by external force impact, the building can resist impacts from both the outside and the inside, thereby improving the safety of personnel in the building.

[0062] In this embodiment, when the concrete block 3 is impacted, not only can the steel mesh 2 and the concrete block 3 provide a certain structural strength, but also the energy generated by the external impact can be absorbed by at least one of the protrusions 11 (such as Figure 5Moreover, even if the concrete block 3 has been broken, the fragments of the concrete block 3 can still be limited by the metal woven mesh (that is, limited in the gap G between the plurality of metal wires W) and will not fall off as a whole. Therefore, a certain structural strength can still be maintained, and the safety of the personnel in the building can also be ensured.

[0063] Based on the same technical concept, Figure 6 As shown, in the support group forming step S1, the support group S may also include a metal mesh 1 and two steel meshes 2. At this time, the two steel meshes 2 respectively press against the first surface 1a and the second surface 1b of the metal mesh 1 to form a sandwich structure with the metal mesh 1. After the positioning step S2 and the casting step S3 are sequentially performed, the obtained concrete block 3 is embedded with two steel meshes 2, which is more convenient than the concrete block 3 with only a single steel mesh 2 (such as Figure 4 As shown), the building can have better structural strength.

[0064] like Figure 7 As shown, the support group S may further include two metal meshes 1 and a steel mesh 2, and the two metal meshes 1 respectively use the second surface 1b to press against two opposite surfaces of the steel mesh 2 to form a sandwich structure with the steel mesh 2. The convex portions 11 of the two metal meshes 1 may be as shown in FIG. Figure 7 The convex part 11 of one metal mesh 1 may be aligned with the concave part 12 of another metal mesh 1, which is not limited here. After the positioning step S2 and the casting step S3 are performed in sequence, the obtained concrete block 3 is embedded with two metal meshes 1 respectively abutting against two opposite surfaces of the steel mesh 2, which is more convenient than the concrete block 3 with only one metal mesh 1 (such as Figure 4 As shown in the figure, the building can withstand greater external impact.

[0065] In addition, Figure 8 As shown, in order to reduce the thickness of the obtained concrete block 3, in the support group forming step S1, the staff can also choose to use a metal mesh 1 having a plurality of convex portions 11 and a plurality of concave portions 12 that present an alternating and repeated wave shape. It is worth noting that along a first direction D1, the plurality of convex portions 11 and the plurality of concave portions 12 present an alternating and repeated wave shape, and along a second direction D2 perpendicular to the first direction D1, the plurality of convex portions 11 form a group and are arranged in a row, and between the plurality of convex portions 11 that form another group and are arranged in a row, there are a plurality of concave portions 12 that form a group and are arranged in a row, and the plurality of concave portions 12 that are arranged in a row can form a receiving groove 13 together.

[0066] Next, the staff can combine the metal mesh 1 and the steel mesh 2 so that the plurality of longitudinal bars 22 are respectively accommodated in the plurality of accommodating grooves 13 along the second direction D2. Fig. 9 The thickness of the support group S is reduced as shown (for example, Figure 3 Compared with the thickness of the support group S shown in FIG. 1 ), the thickness of the concrete block 3 finally obtained can be reduced accordingly.

[0067] Please refer to Figure 8 and Fig. 9 The multiple transverse ribs 21 of the steel mesh 2 are arranged along the first direction D1, and are preferably located between two adjacent convex portions 11 along the second direction D2, and between two adjacent concave portions 12 along the second direction D2, so that the thickness of the support group S can be further reduced.

[0068] Please also refer to Fig.10 and Fig.11 In another embodiment, in the support group forming step S1, the metal mesh 1 included in the support group S can be a spot-welded metal mesh, which includes a plurality of transverse metal wires WH and a plurality of longitudinal metal wires WV intersecting with each other, and the intersections are welded to each other, and after the plurality of transverse metal wires WH and the plurality of longitudinal metal wires WV are welded to each other, they are bent to form at least one convex portion 11 facing the first surface 1a. After the positioning step S2 and the casting step S3 are sequentially performed, the obtained concrete block 3 is embedded with the spot-welded metal mesh as the metal mesh 1, which is better than the concrete block 3 (such as the concrete block 3 with the woven metal mesh as the metal mesh 1) Figure 4 As shown), the building can have better structural strength.

[0069] In summary, the construction method of the building of the present invention can absorb the energy of the impact when the building is impacted by an external force by at least one protrusion of the metal mesh buried in the concrete block, thereby preventing the concrete block from being damaged by the external force impact, thereby achieving the effect of improving the structural strength of the building.

[0070] Moreover, the building made by the above method can absorb the impact energy when the building is impacted by external force through at least one protrusion of the metal mesh buried in the concrete block, thereby preventing the concrete block from being damaged by the external force impact, thereby improving the structural strength of the building and achieving the effect of improving the safety of people in the building.

[0071] Although the present invention has been disclosed by the above preferred embodiments, it is not intended to limit the present invention. Any person familiar with the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention. The protection scope of the present invention includes all changes within the meaning and equivalent scope of the above-mentioned patent application. When the above multiple embodiments can be combined, the present invention includes any combination of embodiments.
