Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a concrete stubble-blocking air bag device that does not require roughening. Background Art

[0002] In the floor construction of building construction projects, there are concrete constructions of different grades, high and low. In order to avoid the waste of high-grade concrete, it is necessary to set up barriers to separate concretes of different grades. The existing barriers mainly use tools such as wire mesh and templates to separate the concretes. The installation of such barriers is cumbersome, inefficient, and the quality of the barriers is unstable. If the wire mesh is not fixed stably, it will cause waste of high-grade concrete, thereby increasing construction costs. In severe cases, it will also affect the construction quality. Therefore, a barrier that can be quickly deployed is needed. Utility Model Content

DETAILED DESCRIPTION

[0022] Example

[0023] like Figure 1 to Figure 5 As shown, the chiseling-free concrete airbag device provided in this embodiment includes an inflatable airbag 1, a flexible support plate 2 and a pressure square 3. The inflatable airbag 1 has a rectangular cross-section, and a plurality of flexible pull plates 4 are arranged inside the inflatable airbag 1 along the length direction to keep the inflatable airbag 1 rectangular. The two ends of the flexible pull plate 4 are respectively connected to the inner wall of the inflatable airbag 1. The flexible pull plate 4 is X-shaped or H-shaped, and its purpose is to pull the distance between the two ends of the flexible pull plate 4 to prevent the inflatable airbag 1 from expanding due to compression deformation and affecting the construction accuracy. The two flexible support plates 2 are symmetrically installed on the side walls on both sides of the inflatable airbag 1, and the side walls on the opposite outer sides of the flexible support plates 2 are processed with roughened surfaces 7. The roughened surfaces 7 can roughen the concrete of the adjacent surfaces, and the process of chiseling during the later connection is avoided, thereby improving the construction efficiency. A clamp 8 is provided for locking the end of the inflatable airbag 1. The clamp 8 can be closed at any position of the inflatable airbag 1 to meet the construction needs of various sizes, thereby improving the convenience of the construction of the stubble blocking device. A detachable air nozzle 92 assembly 9 is installed on the inflatable airbag 1 on one side of the clamp 8. The air nozzle 92 assembly 9 is convenient for the air pump to inflate and deflate the inflatable airbag 1. The air nozzle 92 assembly 9 includes a pressure ring 91, an air nozzle 92 and a locking nut 93. The two pressure rings 91 are respectively installed on the inner and outer sides of the inflatable airbag 1. The air nozzle 92 passes through the two pressure rings 91 in sequence from the inner side of the inflatable airbag 1 and is connected to the locking nut 93. Under the action of the two pressure rings 91, the inflatable airbag 1 can be clamped to avoid air leakage. The pressure square 3 is detachably installed above the inflatable airbag 1. The pressure square 3 can be made of wood or steel pipe.

[0024] In order to quickly deploy the stubble blocking device, Figure 1 , Figure 2 As shown, velvet 5 is processed on the outer walls on both sides of the inflatable airbag 1, and hook surfaces 6 are processed on the side walls of the flexible support plate 2 close to the velvet 5. The velvet 5 and the hook surfaces 6 cooperate to form a quick-release connection structure. When in use, the flexible support plate 2 can be quickly arranged according to the construction size, and flexible support plates 2 of different specifications can be selected by using the hook surfaces 6 and the velvet 5, thereby improving construction efficiency.

[0025] In order to improve the installation efficiency of the fixture 8, Figure 3 , Figure 4As shown, the fixture 8 includes a support frame 81 and a locking rod 85 slidably installed in the support frame 81, and the inner walls on the upper and lower sides of the support frame 81 are processed with sliding grooves 82 for the locking rod 85 to slide, and each sliding groove 82 is installed with a slider 83, and the two sliders 83 are processed with coaxially arranged through holes 84, and the locking rod 85 passes through the two through holes 84 to fix the two sliders 83 in connection. When in use, the inflatable airbag 1 is folded and passed around the support frame 81 and the locking rod 85 in a serpentine shape, and then turned over and placed on the support frame 81. At this time, moving the locking rod 85 can achieve rapid locking of the inflatable airbag 1, thereby improving the installation speed of the inflatable airbag 1.

[0026] The method of using the utility model is:

[0027] When in use, the construction site is cleaned, and then the inflatable airbag 1 is laid at the corresponding position according to the construction requirements, and then an air hole that matches the size of the pressure ring 91 is dug on the inflatable airbag 1, and then the two pressure rings 91 are used to clamp the inflatable airbag 1 from both sides, and then the air nozzle 92 is fixed to the pressure ring 91 by using the locking nut 93. The use of the pressure ring 91 can reduce the damage of the air nozzle 92 to the inflatable airbag 1, thereby increasing the service life of the inflatable airbag 1. After the air nozzle 92 is installed, the clamp 8 is installed on the inflatable airbag 1 outside the air nozzle 92. If the distance between the inflatable airbags 1 is not long enough, multiple sections of the inflatable airbags 1 can be spliced ​​together in sequence, and the size of the spliced ​​inflatable airbags 1 can be adjusted using the clamp 8. At least one air nozzle 92 is required on the bag 1. In order to increase the inflation and deflation speed of the inflatable airbag 1, the air nozzle 92 can be increased adaptively. The air nozzle 92 can be connected through an air compressor for rapid inflation. After the fixture 8 is installed, the flexible support plate 2 is bonded to the side wall of the inflatable airbag 1, and finally the pressing square 3 is installed on the inflatable airbag 1. The pressing square 3 is used to press the inflatable airbag 1 to prevent the thrust during concrete pouring from pushing the inflatable airbag 1 and causing the displacement of the stubble blocking device. After the concrete solidifies, the inflatable airbag 1 is deflated, and then the pressing square 3 is released to remove the stubble blocking device. The roughened surface 7 on the flexible support plate 2 can make the concrete surface in contact with it have a roughening effect, thereby eliminating the later roughening process to improve construction efficiency.

[0028] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
