Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering construction, and particularly relates to a detachable internal operation platform for a caisson. Background Art

[0002] During the construction process of a caisson, construction workers need to carry out various operations such as binding the steel bars of the caisson wall and installing the formwork on the inner side of the caisson. Therefore, it is necessary to set up a safety operation platform on the inner side of the caisson for the construction workers to stand and move around.

[0003] Since the caisson is a process of pouring, excavating, and sinking in sections intermittently, it is very difficult to set up a floor-standing operation platform inside the caisson. In engineering, reserved steel sections or steel pipes are often used as the supporting surface of the cantilever platform, but this method requires a large amount of steel, and the embedded parts cannot be recycled, resulting in waste of materials.

[0004] Therefore, when choosing a suitable operation platform, on the one hand, various factors such as construction safety, progress, and cost should be fully considered, and on the other hand, the side wall of the caisson will not be damaged. Content of the Utility Model

[0005] The utility model provides a detachable internal operation platform for a caisson to solve the technical problems pointed out in the background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0007] A detachable internal operation platform for a caisson is arranged on the inner side of the caisson side wall, and includes a plurality of upper reserved holes uniformly arranged at intervals horizontally on the inner side of the caisson side wall and a plurality of lower reserved holes uniformly arranged at intervals horizontally on the inner side of the caisson side wall. The upper reserved holes and the lower reserved holes are arranged in groups corresponding up and down. The platform also includes platform brackets detachably inserted and matched with each group of the upper reserved holes and the lower reserved holes. A scaffolding is set up on a plurality of the platform brackets to form an operation platform.

[0008] Further, both the upper reserved holes and the lower reserved holes are formed by reserving with PVC pipes with a diameter of mm. The upper reserved holes have an inclination of ° with the inner side higher than the outer side and downward. The lower reserved holes are inclined insertion holes with the inner side higher than the outer side.

[0009] Further, the platform bracket is of an isosceles triangle structure. The right-angle side of the platform bracket extends outward with an upper insertion rod for inserting into the upper reserved hole. A diagonal rod is welded on the hypotenuse side of the platform bracket, and the lower end of the diagonal rod extends and is formed with a lower insertion rod for inserting into the lower reserved hole.

[0010] Further, a cross bar is horizontally arranged above the inner side of the platform bracket, and a dense mesh safety net is hung outside the cross bar.

[0011] Further, an anti-falling safety net is horizontally arranged and pulled at the lower part of the side wall of the open caisson.

[0012] Further, the upper reserved holes and the lower reserved holes are arranged in a closed circular shape on the side wall of the open caisson.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a detachable internal operation platform for an open caisson, which is provided with upper reserved holes, lower reserved holes, platform brackets and a scaffold. Among them, a pair of upper reserved holes and lower reserved holes form a group of reserved holes. By inserting platform brackets into several groups of reserved holes and erecting a scaffold on several platform brackets, an operation platform is formed. The platform brackets of the utility model are convenient to install and disassemble, can be reused, and the holes of the upper reserved holes and the lower reserved holes are small, which will not damage the structure of the open caisson and do not affect the waterproof construction after plugging. The structure of the utility model is simple and compact, and has high practicability. Description of the Drawings

The upper reserved holes 21 and the lower reserved holes 22 are arranged in groups corresponding to each other up and down. The platform further includes platform brackets 3 detachably inserted and matched with each group of the upper reserved holes 21 and the lower reserved holes 22, and a scaffolding 4 is erected on a plurality of the platform brackets 3 to form an operation platform.

[0025] The utility model proposes a detachable caisson internal operating platform, which is provided with an upper reserved hole 21, a lower reserved hole 22, a platform bracket 3, and a scaffolding 4, wherein a pair of upper reserved holes 21 and lower reserved holes 22 constitute a group of reserved holes, and an operating platform is formed by inserting platform brackets 3 into a plurality of groups of reserved holes, and setting up scaffolding on a plurality of platform brackets 3. The platform bracket 3 of the utility model is easy to install and disassemble and can be reused, and the upper reserved holes 21 and the lower reserved holes 22 are relatively small, and will not damage the caisson structure, and will not affect the waterproof construction after being blocked. The utility model has a simple and compact structure and high practicality.

[0026] Specifically, as shown in the figure, the upper reserved hole 21 and the lower reserved hole 22 are both formed by pre-reserving a PVC pipe with a diameter of 30 mm.

The platform bracket 3 is an isosceles triangle structure, and the right-angled side of the platform bracket 3 extends outward with an upper insertion rod 32 for inserting into the upper reserved hole 21. The oblique side of the platform bracket 3 is welded with an oblique rod 31, and the lower end of the oblique rod 31 extends to form a lower insertion rod 31 for inserting into the lower reserved hole 22. The utility model reserves two PVC sockets with a diameter of 30 mm on the side wall of the caisson as the fulcrum of the operating platform. To ensure adequate anchoring, the upper reserved hole is embedded with a downward inclination of 5 degrees, and the steel bar with a diameter of 20mm is bent into an isosceles triangle platform bracket 3, with a waist length of 1.0m, and the end connection is welded (full welding). During installation, the tripod body is inserted into the embedded PVC socket, and the distance between adjacent tripod bodies is 1.2m. Scaffolding boards are laid on the upper part for construction workers to stand and walk. The stability principle of the triangle is used to prevent the cantilever construction work platform from falling or overturning on the side close to the cantilever end, which is safe and reliable.
