[0023] The inventors discovered that existing gate towers are typically constructed by on-site casting or masonry. This process requires a large amount of equipment, tools, manpower, and building materials, making it cumbersome, inefficient, and relying heavily on the experience of the construction workers, resulting in inconsistent quality.

[0024] To solve the aforementioned technical problems, the inventors conceived of fully utilizing the advantages of prefabricated construction by dividing the gatehouse into several modules, prefabricating them separately in a factory, and then assembling them on-site during construction. This would greatly improve construction efficiency and ensure building quality.

[0025] Please refer to the following: Figures 1 to 5The prefabricated door sill provided by this utility model is described below. The prefabricated door sill includes a prefabricated platform, several prefabricated support beams 20, several prefabricated step supports 30, and several prefabricated steps. The prefabricated platform is a flat plate. Several prefabricated support beams 20 are spaced apart on the underside of the prefabricated platform, with their bottom surfaces in contact with the ground and their tops connected to the prefabricated platform to support it. Several prefabricated step supports 30 are spaced apart along the circumference on the underside of the prefabricated platform, each prefabricated step support 30 having several support surfaces arranged in a prefabricated step shape, and the tops of the prefabricated step supports 30 connected to the prefabricated platform. Several prefabricated steps are respectively erected on the support surfaces or on the ground and connected to the prefabricated step supports 30.

[0026] Specifically, the precast platform, precast support beam 20, precast step support 30, and precast steps are all precast concrete components, with dimensions set according to actual needs. The precast step support 30 has several support surfaces arranged in a stepped pattern from bottom to top, with equal height differences between adjacent support surfaces. The upper surface of the step is flush with the upper support surface. The precast support beam 20 is a rectangular beam.

[0027] During on-site construction, the foundation is laid first, and then the precast support beams 20 and precast step supports 30 are placed on the ground. Then, several steps are erected from bottom to top on the support surface of the precast step supports 30, with the edge of the upper step overlapping the upper surface of the lower step. Finally, the precast platform is overlapped on top, with the edge of the precast platform also overlapping the upper surface of the lower step, pressing them together to form a whole without the need for other connection methods.

[0028] The beneficial effects of the prefabricated door sill provided by this utility model are as follows: Compared with the prior art, the prefabricated door sill provided by this utility model is composed of a prefabricated platform, a prefabricated support beam 20, a prefabricated step support 30, and a prefabricated step. During on-site construction, the prefabricated platform, the prefabricated support beam 20, the prefabricated step support 30, and the prefabricated step can be assembled together in a certain position and sequence to complete the construction. Compared with on-site construction or casting, the construction efficiency is higher. Moreover, the prefabricated platform and the prefabricated step are supported by the prefabricated support beam 20 and the prefabricated step support 30, forming a large number of hollow structures inside. Compared with the solid structure formed by on-site construction or casting, less building materials are required, which can effectively reduce construction costs.

[0029] like Figure 1 and Figure 3 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, the prefabricated platform is composed of multiple sub-panels 10 spliced ​​together, and the prefabricated support beam 20 is supported at the joint of two adjacent sub-panels 10.

[0030] It should be noted that the sub-panels 10 are polygonal structures that can be assembled together to form a whole flat panel, i.e., a prefabricated platform.

[0031] Preferably, the slab 10 has a rectangular structure, and the assembled prefabricated platform also has a rectangular structure to facilitate production and assembly.

[0032] The precast support beam 20 is supported at the joint of two adjacent slabs 10, which allows the two slabs 10 to share one precast support beam 20, effectively reducing the amount of precast support beam 20 used and lowering production costs. On the other hand, the precast support beam 20 being supported at the joint of two adjacent slabs 10 can also effectively ensure that the two slabs 10 are at the same height at the joint and that their upper surfaces are flush, thus effectively ensuring the quality of the building.

[0033] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, a drainage groove 11 is provided on the partition plate 10 to facilitate drainage.

[0035] It should be noted that the drainage groove 11 is located at the edge of the partition plate 10, and the side of the adjacent partition plate 10 is used as one side of the drainage groove 11. This can make full use of the adjacent partition plate 10 and further reduce the production difficulty. At the same time, it can make one edge of the drainage groove 11 coincide with one seam of the precast platform, making the appearance of the precast platform more beautiful.

[0036] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, the edge of the prefabricated platform is integrally provided with a first anti-slip stripe 12.

[0037] It should be noted that the first anti-slip stripe 12 is either raised or recessed.

[0038] Preferably, the first anti-slip stripe 12 is a plurality of parallel grooves.

[0039] like Figure 4 and Figure 5 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, the bottom of the prefabricated step on the upper side is erected on the top of the prefabricated step on the lower side, so as to press each other together to form a whole, making the overall structure more stable.

[0040] like Figure 3As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, each prefabricated step is composed of several prefabricated steps, and the prefabricated step support 30 is provided at the joint of two adjacent prefabricated steps.

[0041] It should be noted that placing the precast step support 30 at the joint between two adjacent precast steps can effectively reduce the amount of precast step support 30 used and reduce production costs. On the other hand, placing the precast step support 30 at the joint between two adjacent slabs 10 can also effectively ensure that the two steps are at the same height at the joint and that the upper surfaces are flush, thus effectively ensuring the quality of the building.

[0042] Specifically, prefabricated step supports 30 and prefabricated steps are provided on all three sides of the prefabricated gate platform, and two adjacent prefabricated step supports 30 at the corners are perpendicular to each other and connected to form a whole.

[0043] like Figure 1 and Figure 3 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, the prefabricated steps include a number of strip prefabricated steps 41 and a number of corner prefabricated steps 42. The corner prefabricated steps 42 are located at the corner of the prefabricated steps, and the two end faces are set at an angle and are respectively spliced ​​with the strip prefabricated steps 41.

[0044] Specifically, the corner prefabricated steps 42 are located at the corners of the prefabricated steps to improve the overall integrity of the corners and facilitate assembly. The corner angle is set according to actual needs. The length of the strip prefabricated steps 41 is set according to actual needs.

[0045] Preferably, the corner angle of the prefabricated corner step 42 is 90 degrees, and the two end faces are perpendicular to each other.

[0046] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated door platform provided in this utility model, the edge of the prefabricated step is provided with a second anti-slip stripe 43.

[0047] It should be noted that the second anti-slip stripe 43 is either raised or recessed.

[0048] Preferably, the second anti-slip stripe 43 is a plurality of parallel grooves.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
