Description

Technical Field

[0001] This utility model relates to the technical field of municipal bridge construction support platforms, and in particular to a safe municipal bridge construction support platform. Background Technology

[0002] In the current construction of municipal bridges, especially in the construction of bridge piers, in order to ensure the structural strength of the bridge piers, a special construction support platform is used to build the piers layer by layer and pour the concrete layer by layer. This construction method is particularly suitable for municipal bridge support platforms where the construction site is small and there are limitations on large hoisting equipment.

[0003] However, existing municipal bridge construction support platforms have certain defects in actual use. Typically, when the existing construction support platforms are built, the upper and lower platforms are fixed and assembled with sleeve-type fittings using external clamps. However, when the platform is built to a high height, the fittings are subjected to a large load, which limits the construction height and load of the construction platform. Therefore, there is an urgent need to solve this problem. Utility Model Content

[0004] In view of this, the present invention provides a safe municipal bridge construction support platform. The main technical problem to be solved is that the existing equipment assembly method has limitations on the construction height and load-bearing capacity due to the limited load-bearing capacity of the sleeve-shaped components.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a safe municipal bridge construction support platform, comprising a support column, a foot support structure, an assembly connection structure, a construction platform, and a protective net. The support column is fixedly connected to the four ends of the outer wall of the construction platform. The foot support structure is installed on the lower end face of the support column. The assembly connection structure is installed on the upper end face of the support column. The protective net is installed around the outer wall of the construction platform. The foot support structure includes a support foot, a first assembly rod, and a first threaded groove. The first assembly rod is fixedly connected to the upper end face of the support foot. The first assembly rod has a first threaded groove inside. The assembly connection structure includes an assembly block. A second assembly rod is fixedly connected to both the upper and lower surfaces of the assembly block. The second assembly rod has a second threaded groove inside. The support column has an assembly groove inside. The first and second assembly rods are slidably connected to the assembly groove. A fastening bolt is threadedly connected to the inside of the support column. The first and second threaded grooves are threadedly connected to the fastening bolt. Multiple assembly rings are fixedly connected to both sides of the protective net. The multiple assembly rings are fixedly connected to the outer wall of the support column.

[0006] By adopting the above technical solution, and by opening assembly slots on the upper and lower sides of the support column, it is convenient to install the foot support structure under the support column with fastening bolts according to the installation requirements, and to install the assembly connection structure on the upper side of the support column with fastening bolts. This facilitates the installation of the equipment at the working position by installing the foot support structure, and facilitates the layered assembly and installation of the equipment by using the assembly connection structure. The hollow support column, with the addition of a protective net instead of wire mesh, effectively reduces the weight of the upper support platform and the load on the lower support platform while ensuring safety.

[0007] As a further description of the above technical solution: a square groove is provided in the middle of the interior of the construction platform, and a storage groove is provided on one side of the interior of the construction platform. A ladder is rotatably connected inside the storage groove.

[0008] By adopting the above technical solution, the square grooves are designed to facilitate the construction platform to enclose the pier for the upper construction of the pier. The storage grooves facilitate the installation of storage ladders. The ladders facilitate construction workers to move to the upper construction platform. At the same time, the storage grooves on the upper construction platform also make it easier for construction workers to enter the upper construction platform when climbing up the ladder.

[0009] As a further description of the above technical solution: a mating block is rotatably connected to the other side of the escalator, and a mating groove is provided inside the construction platform at the location of the storage groove, and the mating block and the mating groove are movably connected.

[0010] By adopting the above technical solution, the mating block set at the front end of the escalator can be easily engaged in the mating slot when the escalator is stored in the storage slot, ensuring relative stability when the escalator is stored.

[0011] As a further description of the above technical solution: the upper end face of the construction platform is fixedly connected with a fixing rod, and four fixing rods are set. The four fixing rods are set at the middle of the four sides of the construction platform. The outer walls of the fixing rods are fixedly connected with reinforcing ribs on both sides. The side of the reinforcing rib away from the fixing rod is fixedly connected to the outer wall of the supporting column.

[0012] By adopting the above technical solution, the fixed rods and reinforcing ribs effectively improve the structural strength of each layer of the construction platform after it is built.

[0013] As a further description of the above technical solution: the construction platform has a third threaded groove inside, the mating block has a fastening bolt inside the threaded connection, the fastening bolt is threadedly connected to the third threaded groove, and the fastening bolt is threadedly connected to the mating groove.

[0014] By adopting the above technical solution, when the construction platform is being built, after the ladder of the lower construction platform is erected, the ladder of the lower construction platform can be fixed by connecting the fastening bolts on the mating block to the third threaded groove of the upper construction platform.

[0015] As a further description of the above technical solution: the internal threaded connection of the support foot is a fastening bolt, and the fastening bolt is fixedly connected to the ground.

[0016] By adopting the above technical solution, the fastening bolts inside the support legs make it easy to fix the support legs to the working ground of the construction site, ensuring the stability of the lower construction platform.

[0017] As a further description of the above technical solution: the protective net is made of high-density polyethylene, and the assembly ring is made of stainless steel.

[0018] By adopting the above technical solution, the protective net is made of high-density polyethylene, which effectively reduces the weight of the construction platform compared to the traditional integrated iron mesh fence, thereby reducing the load on each layer of the construction platform. The assembly ring is made of stainless steel, which can prevent the assembly ring from rusting in the outdoor wind and sun environment, thus ensuring the safety of the protective net structure.

[0019] By employing the above technical solution, the safe municipal bridge construction support platform of this utility model has at least the following beneficial effects:

[0020] Compared with existing technologies, this safe municipal bridge construction support platform, after the lowest support platform is installed and fixed, an assembly connection structure is installed above the support columns and fixed with bolts. Then, the support platform to be built is lifted by hoisting equipment, so that the lower end of the support column is inserted into the assembly connection structure. Then, the assembled support platform and the support platform below are connected as one unit with bolts. Compared with the traditional external splicing assembly method, this internal insertion assembly method effectively improves the structural strength of the assembly point and increases the load-bearing capacity of each platform after the construction platform is built. At the same time, the hollow design of the support columns and the addition of protective netting instead of wire mesh effectively reduce the weight of the upper support platform while ensuring safety.
