Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a steel embedded part installation and positioning device and its construction method in areas with dense steel reinforcement. Background Technology

[0002] In construction engineering, the installation of steel embedded parts in densely reinforced concrete columns is a common but challenging problem. Traditional methods of installing steel embedded parts involve manually inserting the anchor rods of the embedded parts into the densely reinforced concrete columns, which is time-consuming, labor-intensive, and prone to inaccurate positioning. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a steel embedded part installation and positioning device and its construction method are provided in areas with dense reinforcement, so as to solve the problems of time-consuming, labor-intensive and inaccurate positioning of traditional steel embedded part installation methods in areas with dense reinforcement.

[0004] To achieve the above objectives, a steel embedded part installation and positioning device is provided in areas with dense reinforcement, comprising:

[0005] A spreader beam is installed above a densely reinforced section of a steel structure, and axial insertion holes are provided at both ends of the spreader beam.

[0006] Two support assemblies, each comprising a movable rod and a vertically arranged insert, one end of each movable rod being movably inserted into two axial insertion holes of the spreader beam, the other ends of the two movable rods being connected by an elastic tie member, the upper end of the insert being connected to the movable rod, and the lower end of the insert being inserted into the steel reinforcement structure;

[0007] The jack, which is used to push the steel embedded part downward so that multiple anchor rods of the steel embedded part are inserted into the densely reinforced area, is installed at the bottom of the spreader beam.

[0008] Furthermore, the jack is vertically positioned and has a fixed end and a telescopic end, with the fixed end connected to the middle of the spreader beam.

[0009] Furthermore, the embedded steel plate is detachably connected to a base, and a vertically arranged guide sleeve is connected to the base, with the telescopic end movably inserted into the guide sleeve.

[0010] Furthermore, the lower end of the insert is welded to the reinforcing bars of the steel structure.

[0011] Furthermore, a vertical channel is formed inside the insert, and a through hole communicating with the vertical channel is opened at the lower end of the insert. A drive rod is installed in the vertical channel in an adjustable manner along the axial position of the vertical channel. An inclined pull-out rod is hinged to the lower end of the drive rod. The end of the pull-out rod away from the drive rod is movably inserted into the through hole. After adjusting the position of the drive rod, one end of the pull-out rod extends to the outside of the insert and is supported at the bottom of the horizontal reinforcing bar of the steel structure to prevent the insert from slipping out of the steel structure.

[0012] Furthermore, the through hole is provided along the radial direction of the insert.

[0013] Furthermore, there are four through holes, which are equally spaced. The lower end of the drive rod is hinged with four anti-pull rods, one end of each of the four anti-pull rods being movably inserted into one of the four through holes.

[0014] Furthermore, the movable rod has a vertical through hole communicating with the upper end of the vertical channel. The vertical through hole is coaxially arranged with the vertical channel. The upper end of the drive rod has an external thread, and the vertical through hole has an internal thread. The upper end of the drive rod is screwed into the vertical through hole, and the lower end of the drive rod is rotatably connected to an adapter rod. The adapter rod is hinged to the other end of the pull-out rod.

[0015] Furthermore, the adapter rod is coaxially arranged with the drive rod.

[0016] This invention provides a construction method for a steel embedded part installation and positioning device in areas with dense reinforcement, comprising the following steps:

[0017] Steel embedded parts are placed in areas of dense reinforcement in reinforced structures;

[0018] The spreader beam is positioned above the embedded steel plate of the steel embedded part;

[0019] Adjust the position of the movable rods of the two support components in the axial insertion holes of the spreader beam so that the lower end of the insert of the support component is inserted into the gap of the steel bars in the steel structure;

[0020] The lower part of the insert is fixedly connected to the reinforcing steel of the steel structure;

[0021] Start the jack, which pushes the pre-embedded steel plate of the steel embedded part downward so that the multiple anchor rods of the steel embedded part are inserted into the dense area of ​​the steel reinforcement.

[0022] The beneficial effects of this invention are as follows: the steel embedded part installation and positioning device for densely reinforced areas utilizes support components installed on both sides of a spreader beam, which are connected to the reinforcing steel structure. Then, the anchor rod of the steel embedded part is pressed into the gaps between the reinforcing bars in the densely reinforced area of ​​the reinforcing steel structure using the force of a jack. This steel embedded part installation and positioning device for densely reinforced areas can quickly and accurately install steel embedded parts in the designed positions in the densely reinforced areas of concrete columns, improving installation efficiency, saving manpower, and ensuring installation accuracy.
