AI Technical Summary
The hollow concrete exterior wall extruded board is not firmly fixed during the construction process, which is easy to move left and right, float up, and deflect, and the pads are prone to fall off, resulting in poor project quality and appearance, and it is also difficult to close the metal formwork.
The extruded plate is fixed by threaded rod and conical nut. The threaded rod is penetrated through the through holes on both sides of the extruded plate. The conical nut and the threaded rod are matched with wire tightening and fixed to the horizontal steel bar to ensure the stability of the extruded plate.
It effectively solves the problem of positioning and floating of the extruded board during the pouring process, enhances the fixity of the extruded board, avoids the difficulty of falling off the pads and clamping the metal formwork, and improves the quality and appearance of the project.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering, and specifically relates to a fixing structure for extruded polystyrene boards on a hollow concrete exterior wall. Background Art
[0002] When constructing a hollow concrete exterior wall, the extruded polystyrene board is usually fixed by passing a steel bar head through the extruded polystyrene board and tying a concrete cushion block between the steel bar head and the extruded polystyrene board. However, it is found in the actual operation process that the cushion block is extremely easy to fall off, and the extruded polystyrene board is easy to move left and right, float and tilt during the pouring process, resulting in the extruded polystyrene board leaking on the concrete surface, which has a great impact on the project quality and appearance. At the same time, when the metal formwork is closed, the metal formwork is difficult to close due to the non-central placement of the steel bar head and the obstruction of the concrete cushion block. Summary of the Invention
[0003] The utility model aims to overcome the defects of the prior art, and provides a fixing structure for extruded polystyrene boards on a hollow concrete exterior wall, so as to solve the problems that the extruded polystyrene board on the hollow concrete exterior wall is not firmly fixed and the extruded polystyrene board is easy to deviate during the pouring and vibration process.
[0004] In order to solve the above technical problems, the utility model is realized as follows:
[0005] A fixing structure for extruded polystyrene boards on a hollow concrete exterior wall includes an extruded polystyrene board, and the extruded polystyrene board is placed into the wall from the top of the steel bars of the hollow concrete exterior wall. It is characterized in that: it further includes a threaded rod and a tapered nut; through holes are symmetrically arranged on both sides of the extruded polystyrene board, the threaded pipe penetrates into the through holes of the extruded polystyrene board, the tapered nuts are sleeved at both ends of the threaded rod, and the threaded rod and the horizontal steel bars of the hollow concrete exterior wall are tightened and fixed by binding wires.
[0006] The fixing structure for extruded polystyrene boards on a hollow concrete exterior wall is characterized in that: anti-rust coatings are provided at both ends of the threaded rod.
[0007] The fixing structure for extruded polystyrene boards on a hollow concrete exterior wall is characterized in that: the tapered nut is made of plastic material.
[0008] The beneficial effects of the utility model are: it can be seen from the above technical solutions that the present application provides a fixing structure for extruded polystyrene boards on a hollow concrete exterior wall. By improving the reinforcement method of the extruded polystyrene board on the hollow concrete exterior wall, the problems of the extruded polystyrene board moving left and right, floating, skewing, cushion block falling off and the difficulty of closing the metal formwork during the concrete pouring process are effectively solved, the construction process of the extruded polystyrene board is optimized, and the project quality and appearance are improved. The present application plays a role in fixing the extruded polystyrene board, preventing tilting and floating, and at the same time solves the problem of the difficulty of closing the metal formwork.
[0009] This application solves the basic problem that the common practice cannot fix the position of the extruded polystyrene board, and also solves the problem of difficult mold closing of the metal formwork; the construction process is relatively simple, with relatively low requirements for the technical level of construction workers, and this construction technology is more easily popularized and used; the rod body is fixed with binding wire, using common materials and obtaining materials locally, and using plastic nuts can reduce the self-weight and meet the force requirements; the raw materials used are relatively environmentally friendly, which not only responds to the national call for green environmental protection but also can reduce the project cost and meet the construction requirements.

[0016] The operation steps of this application are as follows:
[0017] ① Customize threaded rods and plastic tapered nuts (narrow head, wide head) with specific diameters and lengths. Reserve the protective layer thickness to eliminate the later process of painting antirust paint, and at the same time ensure that the deviation of the threaded rod is within a controllable range, without affecting the mold closing of the metal formwork.
[0018] ② After the steel bars of the hollow concrete exterior wall are tied, place the 100-mm-thick extruded polystyrene board into the wall from the top of the steel bars of the hollow concrete exterior wall.
[0019] ③Use a pistol drill to drill diameter holes at the four corners of the extruded polystyrene board, and then insert the threaded rod into the extruded polystyrene board.
