Description

Technical Field

[0001] This invention relates to the field of building formwork technology, specifically to a refined steel formwork for subway pedestrian walkways and its laying method. Background Technology

[0002] Pedestrian walkways are typically constructed using mortar pouring. Therefore, before laying, a pouring template needs to be erected at a predetermined location. After the mortar is poured and solidified, the template can be removed, forming a stable pedestrian walkway.

[0003] Extensive research revealed existing technology: Publication number CN107558726A discloses a multi-functional casting template. This template is curved, forming a casting negative surface and a casting positive surface. Both the negative and positive surfaces are flat. The multi-functional casting template has a multi-layered, hollow structure, with connecting parts at its edges. These connecting parts connect to corresponding connecting parts of other multi-functional casting templates, ensuring the flatness of both the negative and positive surfaces after connection. Because the multi-layered structure of this invention's multi-functional casting template allows the connecting structures between the templates to be located within the layers rather than on the surface. This ensures the smoothness and flatness of the casting negative and positive surfaces formed by the curved template, enabling them to be used for casting external and internal corners, thus improving the utilization rate of the multi-functional casting template and reducing resource waste.

[0004] In summary, when using existing casting formwork, if the roadbed is uneven, the lower end of the traditional steel structure formwork is mostly straight, which cannot effectively seal the low-lying areas of the roadbed. This can lead to mortar leakage during mortar pouring, affecting the pouring effect. Summary of the Invention

[0005] The purpose of this invention is to provide a refined steel formwork for subway pedestrian walkways and its laying method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a refined steel formwork for subway pedestrian walkways and its laying method, comprising a formwork, an end block, a first stud, a second stud, a through groove, and a sealing plate. Two formworks are provided, each with equidistantly distributed second screw holes on its upper surface. A second stud is rotatably inserted into each of the second screw holes. A sealing plate is provided on opposite sides of each of the two formworks. A through groove is provided on the inner wall of the bottom end of each formwork. The lower end of the second stud is rotatably inserted into the sealing plate. An end block is rotatably sleeved on the outer wall of the upper end of the second stud. A first stud is welded to one side of the end block. A tie rod is provided between the two formworks, with second screw holes provided at both ends of the tie rod.

[0007] The bottom outer wall of the template is welded with equidistant positioning seats, and the surface of each positioning seat is provided with anchor holes.

[0008] Preferably, an anchor bolt is inserted into the anchor hole.

[0009] Preferably, the lower end of the sealing plate is inserted into the through groove, and the upper end of the sealing plate is thicker than the width of the inner wall of the through groove.

[0010] Preferably, the length of the sealing plate is adapted to the length of the through groove, and the length of the through groove is less than the length of the template.

[0011] Preferably, the inner wall of one side of the through groove is flush with the outer wall of the template, and the sealing plate is made of hardened rubber.

[0012] Preferably, the upper end of the sealing plate has a second limiting hole that matches the bottom end of the second stud.

[0013] Preferably, the bottom end of the end block has a first limiting hole that matches the upper end of the second stud.

[0014] Preferably, a hexagonal block is welded to the outer wall of the upper end of the second stud.

[0015] Preferably, the threads on the inner walls of the first screw holes at both ends of the pull rod are in opposite directions, and the first studs are engaged with the first screw holes.

[0016] The preferred laying method is as follows:

[0017] S1: The staff first places one side of the template according to the position requirements and fixes it with anchor bolts;

[0018] S2: Rotate the second stud according to the actual roadbed conditions, so that the second stud descends, squeezing the sealing plate down, and sealing the gap between the template and the roadbed through the lower end of the sealing plate;

[0019] S3: Install the template on the other side, and repeat step S2, adjusting the position of the end blocks of the two templates;

[0020] S4: Connect the tie rods between the end blocks, insert the first studs on the surface of the end blocks into the second screw holes respectively, and adjust the spacing between the two templates by rotating the tie rods until the construction requirements are met;

[0021] S5: Pour cement mortar between the two templates.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention allows for longitudinal adjustment of the sealing plate according to the flatness of the roadbed. By using a second stud to spin-press the sealing plate, it can fully adhere to the roadbed surface, preventing leakage during mortar pouring. Compared to traditional fixed-shape plates as sealing components, the rubber sealing plate, combined with the spin-pressing and positioning of the second stud, can better fit the gap between the roadbed and the template, achieving effective mortar sealing and ensuring the pouring effect.

[0024] 2. This device can be flexibly adjusted according to actual usage requirements, and has the advantages of low cost, economic applicability and easy operation. Attached Figure Description
