Description

Technical Field

[0001] The utility model relates to the technical field of built-in boxes, in particular to a built-in box for a hollow floor. Background Art

[0002] Hollow-core floor is a construction technology that reduces the weight of the structure by leaving a cavity in the floor slab, reduces the amount of reinforced concrete, and improves the building's load-bearing capacity and sound insulation. Built-in box is a method of achieving hollow-core floor, which is usually used in buildings with large spans and large spaces, such as commercial buildings, office buildings, libraries, exhibition halls, etc.

[0003] The utility model patent application document with the publication number of "CN216239252U" discloses a built-in box for hollow floor slabs, which relates to the technical field of built-in boxes for buildings, including a built-in box shell, the outer surface of which is symmetrically provided with four vertical connection grooves, a top cover is provided above the built-in box shell, the upper surface of which is provided with a transverse connection groove, a mounting block is provided at the front end of the built-in box shell, a connecting rod is connected to the inside of the mounting block, a limiting hole is provided on the upper surface of the connecting rod, a limiting block is provided at the rear end of the connecting rod, and a fixing rod is arranged on the upper surface of the mounting block; and a mounting plate is symmetrically arranged at both ends of the built-in box shell. The built-in box for hollow floor slabs is provided with a mounting block, and the connecting rod is manually pulled to connect the front end of the connecting rod with the steel bar, and then the connecting rod is inserted into the limiting hole through the mounting block, so as to fix the connecting rod, so that the built-in box shell can be limited, and the displacement during pouring can be reduced.

[0004] The built-in box for hollow floor slabs disclosed in the above document has the following defects: when fixing, the technical solution needs to use wire to install the connecting rod on the surrounding steel bars for fixing, which is relatively troublesome.

[0005] It can be seen from this that the existing built-in box for hollow floor slabs does not have a good fixing component, and it is necessary to improve the existing shortcomings and provide a built-in box for hollow floor slabs. Utility Model Content

[0006] The utility model aims to provide a built-in box for a hollow floor slab to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a built-in box for hollow floor, comprising a built-in box body, through grooves are provided on both sides of the built-in box body, a transverse connecting groove is provided on the upper surface of the built-in box body, vertical connecting grooves are provided on both sides of the built-in box body, and limiter components are provided inside the through grooves;

[0009] The limiting assembly includes a sliding rod, a first limiting plate, a spring, a second limiting plate, a mounting plate pulling handle, an extension rod, a mounting sleeve, a connecting rod, a hook and a mounting slot, wherein the first limiting plate is slidably connected to the interior of the through slot, a spring is fixedly installed on one side of the first limiting plate, the spring is connected to the inner wall of the built-in box body, a second limiting plate is fixedly installed on the peripheral side of the sliding rod, and the second limiting plate abuts against the outer surface of the built-in box body, a mounting plate is fixedly installed on one end of the sliding rod, a pulling handle is fixedly installed on both sides of the mounting plate, an extension rod is fixedly installed on one side of the mounting plate, and one end of the extension rod is fixedly installed A mounting sleeve is fixedly installed, and a connecting rod is fixedly installed on the inner wall of the mounting sleeve, and a hook is provided inside the mounting sleeve, and a mounting groove is opened on one side of the hook, and the mounting groove is rotatably connected to the connecting rod, and the sliding rod is made to slide inside the through groove by pulling the pulling handles on both sides. The sliding of the sliding rod makes the first limit plate squeeze the spring against the inner wall of the built-in box body to contract the spring, thereby extending the sliding rod, and then the hook is hung on the surrounding steel bars, and the hook is hung tightly on the steel bars through the rebound of the spring and will not fall off, thereby achieving the purpose of stabilizing the built-in box body and facilitating fixation, thereby improving the work efficiency of fixing the built-in box body.

[0010] Furthermore, the inner wall of the built-in box body is provided with a reinforcement layer.

[0011] Furthermore, an anti-corrosion layer is provided on the inner wall of the reinforcement layer.

[0012] Furthermore, a sound insulation inner plate is fixedly installed inside the built-in box body, and a plurality of cross reinforcement plates are fixedly installed on both upper and lower sides of the sound insulation inner plate, and the cross reinforcement plates are connected to the built-in box body.

[0013] Furthermore, fixing plates are fixedly installed on both sides of the built-in box body, and a plurality of auxiliary grooves are formed on the outer surface of the fixing plates.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model pulls the pull handles on both sides to make the slide bar slide inside the through groove. The sliding of the slide bar causes the first limit plate to squeeze the spring against the inner wall of the built-in box body to shrink the spring, thereby extending the slide bar. The hook is then hooked on the surrounding steel bars. The spring rebounds to make the hook tightly hooked on the steel bars and prevent it from falling off, thereby stabilizing the built-in box body and facilitating fixation, thereby improving the work efficiency of fixing the built-in box body.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
