Description

Technical Field

[0001] The utility model relates to but is not limited to the technical field of building construction, and specifically relates to a novel cast-in-place pile reinforcement cage wellhead support. Background Art

[0002] During the construction of pile foundation engineering, due to the on-site connection of steel cage segments, it is necessary to temporarily support the lower steel cage during the connection process to facilitate the connection construction of the steel cage segments and control the elevation of the pile top.

[0003] At present, after the bored pile is completed and accepted, the steel cage is lowered. When connecting the steel cage segments, a single steel pipe or wooden beam is used to cross the steel cage. The bearing capacity is limited and can only be temporarily supported for steel cages with fewer segments. When there are more segments, the overall weight of the steel cage will increase, and a single steel pipe or wooden beam will not be able to support it, and will be bent or broken, causing the steel cage to fall off directly, affecting the connection of the steel cage. In order to ensure the connection of the steel cage, a steel cage wellhead bracket is set at the hole of the pile foundation to solve the problem. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a novel cast-in-place pile steel cage wellhead support.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a new type of cast-in-place pile reinforcement cage wellhead support, comprising an outer frame, wherein the upper surface of the outer frame is provided with support components at four corners, wherein the support components include two support rods, a reinforcement plate and a fixing plate, wherein the reinforcement plates are arranged at the upper and lower ends of the two support rods, and the fixing plates are welded to the rear ends of the support rods;

[0007] A support rod fixing part, which is arranged between the support assembly and the outer frame, and includes a fixing block, a limiting column and a reinforcing rod. The fixing block is welded to the four corners of the upper surface of the outer frame, the limiting column penetrates the fixing block horizontally, and the reinforcing rod penetrates the outer end of the limiting column vertically.

[0008] As a preferred technical solution of the utility model, a steel plate is welded between the two support rods, which is designed as an H-shaped steel. A hook is provided at the front end of the support rod, and the hook is a sinking anti-slip hook design. The fixing plate is welded to the support rod.

[0009] As a preferred technical solution of the utility model, a through hole adapted to the support rod is opened inside the fixed block, the support rod is slidably connected to the fixed block through the through hole, and a limiting hole adapted to the limiting column is opened on one side of the fixed block and the support rod.

[0010] As a preferred technical solution of the utility model, the limiting column passes through the fixing block and the supporting rod through the limiting hole, and is threadedly matched with the fixing block and the supporting rod. The outer end of the limiting column is provided with a connecting hole adapted to the reinforcing rod.

[0011] As a preferred technical solution of the utility model, the reinforcing rod passes through the limiting column through the connecting hole, a fixing nut is embedded in the bottom of the outer end of the limiting column, the reinforcing rod passes through the fixing nut and is threadedly matched with the fixing nut and the outer frame.

[0012] As a preferred technical solution of the utility model, the outer frame is formed by welding four steel pipes into a rectangular frame, and four inclined plates are arranged on the inner side of the rectangular frame. The four inclined plates form a hexagonal structure in the rectangular frame.

[0013] As a preferred technical solution of the utility model, the four corners of the outer frame are welded with lifting ears.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model disperses the ground pressure by arranging an outer frame and is used in rotation within the construction site. The support rods on the outer frame are used to hook the steel cage, and the support rods are fixed and limited by the support rod fixing parts, so that the support is not easy to deform and can be reused many times, which solves the problem that when a single steel pipe or wooden beam is used to cross the steel cage, the overall weight of the steel cage will increase when there are many sections, and the single steel pipe or wooden beam will not be able to support it and will be bent or broken, causing the steel cage to fall off directly, thereby affecting the connection work of the steel cage.
