Description

Technical Field

[0001] The utility model relates to the technical field of metal buckles, in particular to metal quick-install buckles for fixing mesh sheets in the production of aerated concrete plates. Background Art

[0002] During the production process of aerated concrete slabs, steel mesh needs to be placed in the aerated concrete. According to different specifications and usage requirements, the mesh has two layout forms: single-layer and double-layer. The double-layer mesh is fixed and connected by connectors to form a mesh cage. During production, the mesh is fixed by a series of tooling equipment such as connectors, steel chisels, chisel racks, and assembly frames. The fixed steel mesh is fixed by steel chisels and placed in the mold with the slurry poured. The mesh at each steel chisel position is fixed by a group of two different connecting pieces, and each mesh is fixed by multiple groups of steel chisels. In the next step of the curing process, the slurry in the mold is gasified and expanded to fill the entire mold, completely wrapping the mesh and connectors in the blank, and at the same time the slurry is initially solidified and thickened to form a solid blank. After the curing is completed, the steel chisel that fixes the mesh needs to be pulled out of the formed blank, and the entire fixing tooling equipment is taken away, leaving the steel mesh and connectors in the blank, and then a series of processes such as cutting and maintenance are carried out to form the finished product.

[0003] During the production process, the steel bar needs to position and fix the mesh through the connector. After the curing is completed, the steel bar needs to be detached from the mesh and the connector and pulled out, leaving the mesh and the connector in the blank. Therefore, it is required that the steel bar and the connector can be both locked and separated. At the same time, the connector left in the blank must not affect the product quality. The national standard "Autoclaved Aerated Concrete Board GB / T15762-2020" stipulates that the connector must be metal connector.

[0004] At present, in the actual production process of aerated concrete panels, most of the connectors are non-metallic plastic clips, and very few are welded with sheet metal connectors; the overall structural size of the non-metallic plastic clips is relatively large, and the tuberculosis with the green body slurry is very poor. The large-size structure affects the expansion of the slurry during the green body curing stage, and it is easy to form large pores and other hole structures on its upper part, affecting the product quality. At the same time, in the subsequent curing and steaming process of production, at a high temperature of nearly 200°C, the plastic clips melt, carbonize, and fail, forming relatively large voids in the green body, affecting the product quality; the use of sheet metal connectors for welding also has a large plane area size, which affects the expansion of the slurry during the curing process, and it is easy to form large pores and other hole structures on its upper part, affecting the product quality. At the same time, the sheet metal connectors need to be welded before assembly and welded to the mesh by an electric current welding machine. The number of connectors is large, the welding efficiency is low, the labor intensity is high, and the position accuracy of manual welding is also difficult to guarantee. After welding, storage and transportation are also relatively troublesome, and the subsequent assembly is labor-intensive. Summary of the invention

[0005] The problem to be solved by the utility model is to provide a welding-free metal quick-release buckle for fixing mesh produced based on aerated concrete slabs, to solve the problem that non-metallic plastic buckles affect product quality and do not meet the current relevant national standards; to solve the problem that sheet-like welded metal connectors affect product quality and have high labor intensity, low efficiency, low precision, and inconvenient operation.

[0006] In order to solve the above technical problems, the utility model is realized through the following technical scheme; the welding-free metal quick-release buckle for fixing the mesh produced by aerated concrete slab is divided into metal buckles for single mesh and metal buckles for double mesh according to the use of single and double meshes; the buckles are in a group of two, the round hole buckle is used for circumferential fixation of the mesh, and the locking buckle is used for circumferential and axial fixation of the mesh.

[0007] Preferably, in order to better fix and position the mesh, improve product quality, and facilitate production and processing, the buckles are made of thin metal steel bars.

[0008] Preferably, in order to solve the fixation and detachment of the steel bar and the buckle, the upper buckle adopts a circular structure that cooperates with the steel bar and is used for circumferential fixation of the mesh; the lower buckle adopts a rectangular or elliptical structure that cooperates with the locking head of the steel bar; the buckle and the steel bar cooperate with each other with an appropriate gap to facilitate installation operations.

[0009] Preferably, in order to facilitate the quick connection between the buckle and the mesh, the buckle opening of the mesh adopts an arc trumpet-mouth structure.

[0010] Preferably, in order to ensure that the buckle is firmly and reliably connected to the mesh, the buckle mesh fixing position is selected to be smaller than the diameter of the mesh connecting steel bar.

[0011] Working principle: The steel drill body is a cylindrical structure. In order to facilitate the installation and fixation of the buckle, the drill head at the lower end is in the shape of a flat arrow. The root of the arrow is in the shape of a small cylindrical bottleneck. The width of the arrow is consistent with the size of the steel drill cylinder, and the thickness is consistent with the size of the small cylinder at the bottleneck. The buckle is used in groups of two, with a round hole buckle at the upper end and a locking buckle at the lower end. In actual use, multiple groups are used together.

[0012] During assembly, rotate the steel chisel to the locking position, insert the round hole buckle into the cylindrical section of the steel chisel, insert the locking buckle into the locking head position of the steel chisel according to the direction of the arrow and rotate 90°, lock the locking buckle on the steel chisel through the bottleneck position at the root of the arrow, and insert the mesh into the buckle through the mesh buckle mouth, and the mesh is fixed on the steel chisel; when pulling out the chisel, rotate the steel chisel 90° to disengage the locking buckle and the steel chisel from the locking position, pull out the steel chisel, and leave the mesh and the buckle inside the blank.

[0013] The beneficial effects of the utility model are as follows: the welding-free metal quick-install buckle for fixing the mesh in the production of aerated concrete panels has a simple structure, is easy to process and manufacture, is convenient and quick to install, and has a firm and reliable connection; it effectively solves the problems of uneven body wrapping, large air holes, etc., reduces labor intensity, and improves production efficiency and product quality.
