Description

Technical Field

[0001] The utility model relates to the field of fixed buildings, in particular to a concrete pouring partition device. Background Art

[0002] In modern construction, the pouring of high- and low-grade concrete is a common occurrence, typically occurring in high-grade walls or columns, low-grade beams or slabs, and between high-grade beams and low-grade secondary slabs. Traditionally, high- and low-grade concrete pouring is accomplished by using partitions such as wire mesh or quick-close mesh to separate the high- and low-grade concrete. However, this method has drawbacks such as the mesh being easily pierced by concrete, requiring a single investment, making operation difficult, and resulting in poor finish appearance. Wire mesh ruptures can lead to waste of higher-grade concrete, increasing pouring costs. Utility Model Content

[0003] The purpose of the utility model is to provide a concrete pouring partition device, aiming to improve the problems of poor stability and inconvenience in use of the existing wire mesh structure during the pouring of high and low grade concrete.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: a concrete pouring partition device, comprising:

[0005] A plurality of barrier bladders are provided, and a connecting portion is provided between two adjacent barrier bladders; and

[0006] The limiting frame has a limiting opening in its center, the width of the limiting opening is set to be the same as the width of the blocking capsule, and the bottom of the blocking capsule is inserted into or pulled out of the limiting opening.

[0007] Preferably, a self-sealing air nozzle is provided on the top surface of the barrier bag.

[0008] Preferably, the barrier bladder is made of a double-layer mesh cloth of PVC.

[0009] Preferably, a plurality of the barrier bladders are arranged in a row structure, and the cross-sectional area of the barrier bladders located on the end sides is smaller than the cross-sectional area of the barrier bladders located in the middle, and the width of the limiting opening is set to be the same as the width of the largest barrier bladder.

[0010] Preferably, the barrier capsule is an elliptical column structure or a regular polygonal column structure.

[0011] Preferably, the barrier capsule is a cylindrical structure.

[0012] Preferably, the diameter of the barrier bladder is 30-70 mm, and the length of the barrier bladder is 800-1500 mm.

[0013] Preferably, the connecting portion is a PVC cloth provided on the top of the barrier bladder, and the connecting portion is a suture structure, a snap button structure, or a nylon button structure.

[0014] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0015] 1. Barrier bladders are arranged in rows. When inflated, they form a "wall" structure that blocks the pouring of cement, thereby achieving a separate pouring effect. Furthermore, during the placement of the barrier bladders, to prevent them from shifting, they can be positioned using a limit frame to improve the stability of the barrier when blocking the pouring of cement.

[0016] 2. Using 30-40mm wide barrier bags on both sides can form a concrete protection control layer in the side edge area of the high-grade concrete pouring, which is formed in a convenient area to connect with the pouring of the external formwork and at the same time can achieve good concrete protection purpose.

[0030] Example

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment provides a concrete casting partition device, including a barrier bag 10 and a limit frame 20, a plurality of barrier bags 10 are provided, and a connecting portion 101 is provided between two adjacent barrier bags 10; a limit opening 201 is provided in the middle of the limit frame 20, and the width of the limit opening corresponds to the width of the barrier bag, and the limit opening 201 is provided for inserting or pulling out the bottom of the barrier bag 10.

[0032] Specifically, the concrete pouring partition is used to separate high-grade and low-grade concrete. Specifically, the concrete pouring partition is placed in the beam to be poured, separating the concrete so that different grades of concrete can be poured in different areas. Therefore, the barrier bladder 10 needs to have good wear resistance, for example, made of a double-layer PVC mesh, with an additional layer of wear-resistant fabric on the outer layer to ensure the material strength of the barrier bladder 10.

[0033] During use, after the steel cage 1 to be cast is completed, the limiting frame 20 (which can be made by welding steel bars) can be fixed horizontally in the steel cage 1 by bundling or welding, and the fixed position can be about one-third of the horizontal height of the steel cage 1; at this time, all the barrier capsules 10 are inserted into the limiting opening 201 for shape limiting, and at the same time, the length of the barrier capsule 10 will be greater than the height of the steel cage 1, forming a multi-point support limit, achieving a good fixed installation effect. In this way, after pouring cement, the steel cage 1 can be blocked at the required position. At the same time, the use of the barrier capsule 10 can form a good casting surface on the casting end face, that is, the required protective layer can be formed. Because, if the barrier capsule 10 is offset, etc., it will cause the blocked end face to be irregular, and it is easy for the cast internal steel bars to leak out, or too much cement to overflow, resulting in a problem of reduced strength of the cement structure. Therefore, by using the barrier capsule 10, this problem can be solved, the strength of the cast structure can be improved, and it has good practicality.

[0034] Furthermore, a connector 101 is designed between the barrier bladders 10 for easy handling. After being positioned at the bottom by the retaining frame 20, the top of the barrier bladder is connected by the connector 101, ensuring the integrity of the barrier bladder 10 during the barrier operation and improving the stability of the barrier. Furthermore, the connector can be a PVC fabric molded around the edge of the barrier bladder 10, and can be connected by sewing, snapping, or gluing with nylon buckles.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the top surface of the barrier bladder 10 is provided with a self-sealing air nozzle 102, such as a swimming ring air nozzle, which allows for quick inflation and deflation and is convenient to use. For example, the air nozzle is FHS / Furhausen part number FHS-YPS16302, which can be made of PE plastic and has good sealing properties.

[0036] Furthermore, in this embodiment, a plurality of barrier capsules 10 are arranged in a row structure, and the cross-sectional area of the barrier capsules 10 located on the end side is smaller than the cross-sectional area of the barrier capsules 10 located in the middle, and the width of the limiting opening is set to be the same as the width of the largest barrier capsule. With such a design, the barrier capsules 10 located at the head and tail are relatively thin, while the barrier capsule 10 in the middle is relatively thick, so as to facilitate the removal of the barrier capsules 10. Specifically, when in use, by inflating the barrier capsules 10, the plurality of barrier capsules 10 in a row are abutted against each other to form a "wall" structure for blocking. After the cement pouring is completed, the fine structure design of the barrier capsules 10 at the head and tail ends is not easily squeezed, tilted or deformed by the side, forming an irregular state (such as bending or tilting at different angles, etc.), which makes it difficult to deflate and remove the barrier capsules 10, thereby improving practicality. At the same time, the barrier capsules 10 at the deflation port can be recycled for reuse next time, which has good environmental performance.

[0037] In this embodiment, the barrier bladder 10 has an elliptical cylinder structure or a regular polygonal cylinder structure. Furthermore, the barrier bladder 10 can have a cylindrical structure. The barrier bladder 10 can have a variety of structural designs, such as a cylinder, elliptical cylinder, regular triangular prism, rectangular prism, or regular pentagonal prism, etc. By injecting gas, the bladder expands and abuts against each other, creating a filling and blocking effect for the steel cage 1. Preferably, a cylindrical barrier bladder 10 can be used. The curved surface of the barrier bladder 10 can help withstand greater impact, reduce the probability of damage to the barrier bladder 10, and increase its service life.

[0038] Furthermore, using 40mm-wide barrier bladders 10 on both sides can form a protective layer around the side edges of the high-grade concrete pour, conveniently positioned to interface with the external formwork, while also effectively protecting the concrete. That is, by sizing the barrier bladders 10 at both ends, the thickness of the concrete protective layer can be controlled, avoiding excessive thickness, which could result in a loss of structural strength, or excessive thinness, which could lead to leakage of rebar and loss of protective performance. Furthermore, using 40mm-wide barrier bladders 10 on both sides can form a protective layer around the end edges of the high-grade concrete pour, conveniently positioned to interface with the low-grade concrete pour, while also effectively protecting the concrete. That is, by sizing the barrier bladders 10 at both ends, the thickness of the protective layer can be controlled, avoiding excessive thickness, which could result in a loss of structural strength, or excessive thinness, which could result in leakage of rebar and loss of protective performance.

[0039] Furthermore, according to the different sizes of the steel cage 1, different numbers of barrier bags 10 can be used. For example, the width of four barrier bags 10 can reach 200 mm; the width of five barrier bags 10 can reach 260 mm; the width of six barrier bags 10 can reach 300-320 mm (a 40 mm diameter barrier bag 10 can be inserted in the middle), etc. The length of the barrier bag 10 can be greater than the height of the steel cage 1, so that it cooperates with the limit frame 20 to form a multi-point limiting effect, avoid offset, improve the quality of casting, and the blocking performance.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
