Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method for positioning a ash cake structure and an anti-cracking mesh. Background Art

[0002] In the process of decoration and renovation construction, it is most common to use concrete for the floor base or surface layer. The thickness of the concrete surface layer is about 100mm. If no anti-cracking measures are taken, the surface layer will have quality problems such as hollowing and cracking during the hardening process due to its own solidification and changes in temperature and humidity in nature. In order to prevent the floor from cracking, an anti-cracking mesh or steel fiber is generally set in the concrete surface layer, but due to the high price of steel fiber concrete, the anti-cracking mesh is widely used. In the prior art, in order to prevent the concrete surface layer from cracking, anti-cracking measures such as adding steel mesh or glass fiber mesh to concrete are adopted, that is, steel mesh is first laid during construction, and cement pads are set below the intersection of the steel mesh to ensure that the steel mesh is located in a suitable position below the top surface of the surface layer. Since there is no fixing measure between the pad and the steel mesh, the stability between the pad and the steel mesh is poor. When pouring concrete, it is easy to dislocate, causing the anti-cracking mesh to lose support and fall to the bottom of the concrete, resulting in the failure of the anti-cracking effect of the anti-cracking mesh.

[0003] In the Chinese patent document with application publication number CN118375316A, a construction method for fully paving basalt fiber anti-cracking mesh on a concrete protective layer is disclosed, which comprises first pouring a concrete surface layer, and then paving the basalt fiber anti-cracking mesh on the surface of the concrete surface layer as it is poured. Through vibration and smearing, the anti-cracking mesh is made to sink from the surface of the surface layer to a certain distance below the surface of the concrete surface layer. Although this method can prevent the anti-cracking mesh from sinking into the lowest layer of the surface layer, due to the invisibility of the anti-cracking mesh during the sinking process and the lack of standard support, the distance between the laid anti-cracking mesh and the surface layer is poorly controllable and a fixed standard cannot be formed, resulting in poor anti-cracking effect of the anti-cracking mesh and difficulty in ensuring construction quality. Summary of the invention

[0004] The purpose of the present invention is to provide a construction method for positioning a ash cake structure and an anti-cracking mesh, so that the anti-cracking mesh has stable support during construction, effectively increase the controllability of the distance between the anti-cracking mesh and the surface of the surface layer, and increase the effectiveness of the anti-cracking mesh in the anti-cracking effect of the surface layer.

[0005] In order to solve the above technical problems, the embodiments of the present invention provide a technical solution as follows:

[0006] A ash cake structure comprises a cylindrical body, wherein a groove is arranged on the top surface of the body, and the groove passes through to the side surface of the body in a direction parallel to the top surface. By setting the groove on the top surface of the ash cake, the ash cake is used to replace the anti-crack mesh pad in the prior art, and the mesh is clamped and arranged in the groove on the top surface, so that the anti-crack mesh can play a stable supporting role. At the same time, the setting of the groove enables the anti-crack mesh to maintain a stable distance from the surface layer, effectively increasing the controllability of the distance between the anti-crack mesh and the surface layer, and ensuring the effectiveness of the anti-crack mesh in the anti-crack effect on the surface layer.

[0007] Furthermore, the columnar body is a polygonal column having a bottom surface and a top surface, and the side length of the top surface is smaller than the side length of the bottom surface.

[0008] Furthermore, the body is a regular tetrahedron, and the groove is centrally arranged on the top surface of the body.

[0009] Furthermore, the cross section of the groove is U-shaped.

[0010] Furthermore, the cross section of the groove is arc-shaped.

[0011] Furthermore, the maximum distance between the bottom of the groove and the top surface along the axial direction of the cylindrical body is 15 mm-30 mm.

[0012] In order to solve the above technical problems, the embodiments of the present invention further provide a technical solution as follows:

[0013] A construction method for positioning an anti-crack mesh comprises the following steps:

[0014] Base construction;

[0015] The spacing of the ash cakes is calculated according to the spacing of the mesh wires of the anti-crack mesh, wherein the anti-crack mesh is a grid structure formed by fixing and connecting mesh wires arranged vertically and horizontally, and the spacing of the ash cakes is an integer multiple of the grid spacing;

[0016] On the upper surface of the base layer, any of the above ash cakes are constructed according to the spacing of the ash cakes, and the distance between the grooves on the top surface of the ash cakes is an integer multiple of the grid spacing;

[0017] The anti-crack mesh is clamped and arranged at the bottom of the groove, and the anti-crack mesh is arranged parallel to the base layer;

[0018] Pouring of surface material.

[0019] Furthermore, the pouring construction of the surface material and the construction work of clamping and setting the anti-cracking mesh at the bottom of the groove are carried out simultaneously.

[0020] Furthermore, the spacing between the ash cakes is 1000mm-3000m.

[0021] Furthermore, the ash cake is a prism, and the length of the top surface of the prism is 5 mm, and the length of the bottom surface is 10 mm.

[0022] Compared with the prior art, the ash cake structure and the construction method for positioning the anti-cracking mesh provided by the present invention, through the setting of the groove on the top surface of the ash cake, use the ash cake to replace the anti-cracking mesh pad of the prior art, and the mesh is clamped and set in the groove on the top surface, which can play a stable supporting role for the anti-cracking mesh.

[0033] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection in the claims of the present application can be implemented.

[0034] like Figure 4 As shown, in the prior art, the anti-crack mesh 10 generally adopts a finished mesh. The anti-crack mesh 10 is a grid 11 structure made of mesh wires 12 arranged vertically and horizontally and fixedly connected. To ensure the effectiveness and durability of the anti-crack mesh 10 in construction projects, considering the strength requirements and corrosion resistance, the mesh wires 12 have a variety of material options, for example, steel wire, basalt fiber composite material, steel bar, stainless steel, galvanized steel wire, etc. The common mesh wire 12 has a diameter of 4mm-10mm, and the grid 11 spacing is 50mm-200mm.

[0035] like Figure 1-3 As shown in Figures 6 and 7, an embodiment of the present invention relates to an ash cake 20 structure, including a cylindrical body 200, wherein a groove 23 is provided on the top surface 21 of the body 200, and the groove 23 passes through to the side of the body 200 in a direction parallel to the top surface 21. The cylindrical body 200 can be selected as an equal-diameter cylinder, an equal-diameter polygonal prism, or a truncated cone or a prism. In order to increase the stability and manufacturing convenience of the ash cake 20, in an exemplary example, the cylindrical body 200 is a polygonal prism, provided with a bottom surface 22 and a top surface 21, and the side length of the top surface 21 is smaller than the side length of the bottom surface 22. In order to further increase the stability of the ash cake 20 and the consistency of manufacturing specifications, preferably, the body 200 is a regular tetrahedron, and the groove 23 is centrally arranged on the top surface 21 of the body 200. By setting the groove 23 on the top surface 21 of the ash cake 20, the ash cake 20 is used to replace the anti-crack mesh 10 pad in the prior art, and the anti-crack mesh 10 is clamped and set in the groove 23 on the top surface 21, which can play a stable supporting role for the anti-crack mesh 10. At the same time, the setting of the groove 23 enables the anti-crack mesh 10 to maintain a stable distance from the surface of the surface layer 40, effectively increasing the controllability of the distance between the anti-crack mesh 10 and the surface of the surface layer 40, and ensuring the effectiveness of the anti-crack effect of the anti-crack mesh 10 on the surface layer 40.

[0036] In order to further increase the stability of the combination of the anti-crack mesh 10 and the ash cake 20, and maintain the stability of the distance between the anti-crack mesh 10 and the top surface 21 of the ash cake 20, in one embodiment, as Figure 2As shown, the cross section of the groove 23 is U-shaped. In a different embodiment, as Figure 3 As shown, the cross-section of the groove 23 is arc-shaped. In other embodiments, the cross-section of the groove 23 may also be a trapezoidal structure or a triangular structure. In an exemplary example, the maximum distance between the bottom 231 of the groove 23 and the top surface 21 along the axial direction of the cylindrical body 200 is 15mm-30mm. The depth of the groove 23 determines the distance between the anti-crack mesh 10 and the top surface 21 of the ash cake 20, that is, the distance between the anti-crack mesh 10 and the surface of the surface layer 40 is effectively limited. The depth of the groove 23 can be set according to the thickness of the surface layer 40 and the material used, so that the anti-crack effect of the anti-crack mesh 10 on the surface layer 40 can be stably and effectively exerted.

[0037] like Figure 5-8 As shown, one embodiment provided by the present invention relates to a construction method for positioning an anti-crack mesh 10, comprising the following steps:

[0038] The base layer 30 is constructed; the base layer 30 construction is a conventional operation in the prior art and will not be described in detail here.

[0039] The spacing of the ash cakes 20 is calculated according to the spacing of the mesh wires 12 of the anti-crack mesh 10. The anti-crack mesh 10 is a grid 11 structure made by fixing and connecting the mesh wires 12 arranged vertically and horizontally. The spacing of the ash cakes 20 is an integer multiple of the spacing of the grid 11. Preferably, the spacing of the ash cakes 20 is 1000mm-3000mm. In one embodiment, for example, if the spacing of the grid 11 of the anti-crack mesh 10 is 200mm, that is, the distance between adjacent mesh wires 12 arranged in the same direction is 200mm, then the spacing of the ash cakes 20 can be set to 1000mm, 1400mm, 2000mm, etc.

[0040] On the upper surface of the base layer 30, the ash cakes 20 are constructed as described above according to the spacing of the ash cakes 20, and the distance between the grooves 23 on the top surface 21 of the ash cake 20 is an integral multiple of the spacing of the grid 11; the specifications of each ash cake 20 are consistent, and the spacing between adjacent grooves 23 is the same as the spacing between the corresponding ash cakes 20. Preferably, the ash cake 20 is a prism, and the side length of the top surface 21 of the prism is 5 mm, and the side length of the bottom surface 22 is 10 mm.

[0041] like Figure 5 As shown, the mesh wire 12 of the anti-crack mesh 10 is clamped and set at the bottom 231 of the groove 23, and the anti-crack mesh 10 is set parallel to the base layer 30; preferably, the upper surface of the mesh wire 12 is 15mm-20mm away from the top surface 21 of the ash cake 20.

[0042] Surface layer 40 material pouring construction. The surface layer 40 material pouring construction technology is consistent with the existing technology. Generally, when pouring the surface layer 40 material, a fixed pump or a self-unloading method can be used for pouring.

[0043] In one embodiment, the surface layer 40 material is concrete, and the surface layer 40 material is transported and cast by an electric vehicle. In order to prevent the anti-cracking mesh 10 from being deformed by collision during the transportation of the surface layer 40 material, the construction can be carried out by placing the anti-cracking mesh 10 while casting, that is, the casting construction of the surface layer 40 material and the construction operation of clamping the anti-cracking mesh 10 at the bottom 231 of the groove 23 are carried out simultaneously.

[0044] In the construction implementation of positioning the anti-crack mesh 10 of a concrete surface layer 40 floor, the anti-crack mesh 10 adopts a finished mesh, the mesh specification is 2000mm×3000mm, the grid 11 interval is 200mm, the spacing of the ash cake 20 is 1600mm, in order to ensure the support stability of the ash cake 20, the ash cake 20 is a prism, the bottom surface 22 of the ash cake 20 is 100mm wide, and the top surface 21 is 50mm wide. A fixture or mold is used to press a groove 23 on the top surface 21 of the ash cake 20. The opening width of the groove 23 is 20mm and the depth is 20mm. For example: through a 20mm diameter A PVC pipe is used to press out a groove 23 on the top surface 21 of the ash cake 20. A square pipe with an outer diameter of 20 mm can also be used to press out a groove 23 on the top surface 21 of the ash cake 20. When using a jig or a mold to press out the groove 23 on the top surface 21 of the ash cake 20, it is necessary to work with a wire to ensure the horizontality and parallelism between the grooves 23, which is beneficial for the precise installation of the anti-crack mesh 10 and the grooves 23 of the ash cake 20, so that the anti-crack mesh 10 can maintain a stable distance from the surface of the surface layer 40, effectively increasing the controllability of the distance between the anti-crack mesh 10 and the surface layer 40, and ensuring the effectiveness of the anti-crack effect of the anti-crack mesh 10 on the surface layer 40.
