Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a self-positioning partition airbag component. Background Art

[0002] In structures like frames and frame-shear structures, inconsistent concrete strength grades often occur between beams and columns. Traditionally, this has been addressed with quick-close mesh or wire mesh. However, the mesh's holes fail to isolate the mortar from the concrete, or the mesh is deformed during concrete pouring, causing high-strength concrete in the column to flow into the lower-strength concrete, forming a large diagonal joint. Furthermore, the beam-column junction contains a high number of steel bars and support reinforcement, which happens to be in an area with denser stirrups, making mesh placement unsuitable. To achieve better results, construction workers use an airbag separation method instead of quick-close mesh or wire mesh. This method is easy to operate on-site, reducing the workload for workers and resolving the common quality issue of incomplete isolation between high- and low-strength concrete grades. It offers the advantages of safety, reliability, and affordability.

[0003] Before use, the airbag is deflated. Air or another inert gas (such as nitrogen) is then pumped into it using an air compressor or other inflating device, causing it to expand to the desired size and shape, thus providing a temporary, deformable mold for pouring concrete. However, because the airbag is flat and very soft before inflation, it can be difficult to insert into the corresponding formwork. Once inserted, the airbag can also become misaligned, affecting the placement of the mesh. Utility Model Content

[0004] In response to the above problems, the present invention proposes a self-positioning partition airbag component to solve the problem that the existing partition airbag component is flat and very soft before inflation, and when the airbag is placed in the corresponding template, the airbag is not easy to insert and will be misplaced after placement.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] according to Figure 1 、 2 As shown in Figures 3, 4, and 5, this embodiment proposes a self-positioning partition airbag component, including a bag body 1 and a positioning rod 4. The upper end of the bag body 1 is provided with an air injection port 3, and the side of the bag body 1 is provided with at least one pocket 2, the two ends of the pocket 2 extend toward the two ends of the bag body 1, and the edge of the pocket 2 is fixedly connected to the bag body 1;

[0025] Before use, bladder 1 is deflated. A conduit on the inflation device connects to the gas inlet 3, allowing air or other inert gas to be pumped into bladder 1, causing it to expand to the desired size and shape. Bladder 1 provides a temporary, deformable mold for concrete pouring. After bladder 1 is inflated and reaches the desired shape, it needs to be secured in place to prevent displacement during the concrete pouring process.

[0026] After the bladder 1 is fixed, concrete pouring can begin. The bladder 1 will remain inflated. When the concrete reaches a certain strength and can stand on its own without destroying its shape, the air can be deflated and the bladder 1 can be taken out.

[0027] An opening is left at the upper end of the pocket bag 2 to allow the positioning rod 4 to be inserted therein. The length of the positioning rod 4 is greater than the depth inside the pocket bag 2. The upper end of the positioning rod 4 extends outside the pocket bag 2. The upper end of the pocket bag 2 is provided with a tension adjustment mechanism 5 for fixing the positioning rod 4.

[0028] The sac 1 is flat before being inflated, and it is difficult for the staff to insert the sac 1 into the appropriate position. Therefore, it is necessary to use a positioning rod 4 to assist in positioning the sac 1, that is, to insert the positioning rod 4 into the pocket 2 outside the sac 1, and the pocket 2 will fix the positioning rod 4 and the sac 1 through the elastic adjustment mechanism 5. When placing the sac 1, the staff can adjust the placement position of the sac 1 through the positioning rod 4 and make the sac 1 quickly unfolded. It has high flexibility and the elastic fixing method makes it easy to disassemble and put.

[0029] The specific structure of the tension adjustment mechanism 5 is described below.

[0030] The tension adjustment mechanism 5 includes an elastic ring 51, and a second connecting piece 52 is provided at the lower end of the elastic ring 51. The second connecting piece 52 is fixedly connected to the upper end of the pocket bag 2. A plurality of clamping blocks 55 are provided at the upper end of the second connecting piece 52. Each of the clamping blocks 55 surrounds the positioning rod 4. The outer wall of the clamping block 55 is provided with an external thread. A nut 53 is provided on the outer side of the elastic ring 51, and the nut 53 is threadedly connected to the external thread.

[0031] The tension adjustment mechanism 5 is used as follows: the cross-section of the clamping block 55 is trapezoidal, wide at the top and narrow at the bottom. When the positioning rod 4 passes through the elastic ring 51, each clamping block 55 surrounds the positioning rod 4, and the nut 53 is rotated to rotate the nut 53 from the outside of the elastic ring 51 to the outside of each retaining protrusion 54. As the nut 53 continues to rise, each clamping block 55 will contract at the same time, squeezing the positioning rod 4 to fix the positioning rod 4.

[0032] In order to facilitate the staff to rotate the nut 53, the outer wall of the nut 53 is provided with at least one stop convex 54, and the stop convex 54 is fixedly connected to the nut 53. When rotating the nut 53, the stop convex 54 can be bent.

[0033] In a preferred embodiment, the upper end of the positioning rod 4 is provided with a first handle 41, which is fixedly connected to the positioning rod 4. The outer wall of the first handle 41 is provided with a plurality of dot-shaped protrusions. When inserting or removing the positioning rod 4, the first handle 41 is simply grasped and pulled upward or pushed downward. The dot-shaped protrusions on the outer side of the first handle 41 are used to increase friction between the first handle 41 and the palm of the hand, thereby preventing slipping.

[0034] Based on the previous embodiment, a further improvement can be made. A second handle 42 is provided on the side of the first handle 41. The second handle 42 is perpendicular to the first handle 41 and is fixedly connected to the first handle 41. The outer wall of the second handle 42 is provided with a plurality of dot-shaped protrusions. The right-angle grip shape is designed to make it easier for the user to hold the positioning rod 4.

[0035] It should be further explained that the gas injection port 3 includes a valve seat 31, and a valve cover 32 is provided on the upper end of the valve seat 31. The valve cover 32 is buckled with the valve seat 31. After the gas injection is completed, the valve cover 32 is buckled on the valve seat 31 to ensure that the bladder 1 does not leak.

[0036] To prevent the valve cover 32 from falling off or being lost on the valve seat 31, a first connecting piece 33 may be provided between the valve cover 32 and the valve seat 31. The upper end of the first connecting piece 33 is fixedly connected to the valve cover 32, and the lower end of the first connecting piece 33 is fixedly connected to the valve seat 31. The valve cover 32 is directly fixed to the valve seat 31 via the first connecting piece 33. The first connecting piece 33 can be bent without affecting the opening and closing of the valve cover 32.

[0037] About capsule 1:

[0038] The airbag body 1 includes a puncture-resistant layer 12, with a nylon layer 11 disposed on its inner side, which is fixedly connected to the puncture-resistant layer 12. A resin coating 13 is disposed on its outer side, which is fixedly connected to the puncture-resistant layer 12. The puncture-resistant layer 12 is used to enhance the puncture resistance of the airbag body 1 and extend its service life. The high-quality airbag material allows for multiple reuse after proper maintenance, further improving economic efficiency.

[0039] How this application works:

[0040] Insert the positioning rod 4 into the pocket 2 outside the bag 1, and the pocket 2 will fix the positioning rod 4 and the bag 1 through the tension adjustment mechanism 5. When placing the bag 1, the staff can adjust the placement position of the bag 1 through the positioning rod 4 and quickly expand the bag 1.

[0041] Air or other inert gas is injected into the bladder 1 through an inflation device, causing it to expand to a predetermined size and shape. The bladder 1 provides a temporary, deformable mold for concrete pouring. After the bladder 1 is inflated and reaches the predetermined shape, it needs to be fixed in place to ensure that it does not shift during the concrete pouring process.

[0042] After the bladder 1 is fixed, concrete pouring can begin. The bladder 1 will remain inflated. When the concrete reaches a certain strength and can stand on its own without destroying its shape, the air can be deflated and the bladder 1 can be taken out.
