Description

Technical Field

[0001] This utility model relates to the field of concrete isolation technology, and in particular to a novel high and low grade concrete isolation structure. Background Technology

[0002] In building construction, when different strength grades (i.e., high and low grades) of concrete are used simultaneously in the same structural component (such as beam-column joints or the junction of wall-column and beam-slab), isolation structures (also known as "separation measures") are required to prevent low-grade concrete from flowing into high-grade areas and to ensure the design strength and performance of high-grade concrete. Their core function is to physically separate concrete of different grades, ensuring that the concrete strength at the junction meets design requirements and preventing structural safety hazards caused by mixed pouring.

[0003] However, in terms of construction, traditional mesh installation is cumbersome, complex node handling is difficult, and multiple overlapping processes are prone to interference, resulting in high operational difficulty and long processing times. Regarding isolation effectiveness, concrete is prone to seepage, the mesh is easily displaced, and the interface bonding performance is insufficient, posing risks of grout leakage and fixation failure. Interface treatment is difficult; manual roughening is inefficient and produces uneven quality, and some materials also have durability defects. These problems affect construction quality, create safety hazards, reduce construction efficiency, and increase costs and maintenance frequency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of complex construction, unstable isolation effect and difficult interface treatment of existing isolation structures, and to propose a new type of high and low grade concrete isolation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel high and low grade concrete isolation structure, comprising an isolation net body, a connecting strip fixedly connected to the edge of the isolation net body, a connecting block fixedly connected to one end of the connecting strip, a plurality of limiting blocks sleeved on the outer wall of the connecting strip, the limiting blocks fitting into the corner of the concrete, and an extended isolation net fixedly connected to all four sides of the isolation net body.

[0006] Preferably, the extended isolation net is perpendicular to the main body of the isolation net, and a rubber sleeve is fitted at the junction of the extended isolation net and the main body of the isolation net.

[0007] Preferably, an extension rope is fixedly connected to the other end of the connecting belt, and the extension rope is slidably connected to the connecting block.

[0008] Preferably, the extension rope passes through the connecting block and is bent at ninety degrees before being arranged along the length of the main body of the isolation net.

[0009] Preferably, a cavity is formed on the inner wall of the connecting block, and the cavity is located on both sides of the connecting strip.

[0010] Preferably, a rubber block is fixedly installed on the inner wall of the cavity, and a serrated block is fixedly connected to one end of the rubber block.

[0011] Preferably, one side of the serrated block is attached to the side of the connecting strip and the side of the extension rope.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the splicable connecting structure and limiting block improve the flexibility and stability of the isolation net installation, adapting to construction scenarios of different shapes and sizes. The extended design of the isolation net and rubber sleeve significantly improves the isolation effect, reduces concrete pouring and leakage, ensures the construction quality at the junction of high and low grade concrete, the overall structure is simple and practical, easy to install, can effectively improve construction efficiency, reduce rework costs caused by poor isolation effect, extend the service life of the structure, and enhance the safety and durability of the building structure.

[0014] 2. In this utility model, the tension of the isolation net can be flexibly adjusted according to the construction scene through the linkage mechanism of the extension rope and the sawtooth block, adapting to beam and column nodes of different sizes or irregular corners, improving installation efficiency. The buffering effect of the rubber block avoids damage to the connecting strip caused by rigid clamping. The one-way locking function of the sawtooth block ensures that the isolation net remains stable under the lateral pressure of concrete pouring, avoiding displacement or loosening, and effectively improving the isolation accuracy.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a novel high and low grade concrete isolation structure, including an isolation net body 1, a connecting strip 5 fixedly connected to the edge of the isolation net body 1, a connecting block 4 fixedly connected to one end of the connecting strip 5, a plurality of limiting blocks 7 sleeved on the outer wall of the connecting strip 5, the limiting blocks 7 fitting against the corner of the concrete, and an extension isolation net 2 fixedly connected to all four sides of the isolation net body 1, the extension isolation net 2 being perpendicular to the isolation net body 1, and a rubber sleeve 3 sleeved at the junction of the extension isolation net 2 and the isolation net body 1.

[0023] The specific setup and function of this embodiment are described below. The isolation net body 1 and the extended isolation net 2 are used to separate concrete of different strengths. During use, the connecting block 4 is fitted onto the connecting strip 5, and then the connecting strip 5 is wrapped around the surface of the concrete. The limiting block 7 precisely fits the corner of the concrete, ensuring the isolation net is stably fixed at the corner and preventing displacement during pouring. The extended isolation net 2 also covers other structures connected to the concrete in the same way, effectively blocking lateral flow of concrete. The rubber sleeve 3 at the junction of the extended isolation net 2 and the isolation net body 1 protects the junction area. It is protected from the impact of concrete and fills gaps to prevent grout leakage. Through the splicable connecting structure and limiting block 7, the flexibility and stability of the isolation net installation are improved, adapting to construction scenarios of different shapes and sizes. The design of the extended isolation net 2 and rubber sleeve 3 significantly improves the isolation effect, reduces concrete pouring and grout leakage, and ensures the construction quality at the junction of high and low grade concrete. The overall structure is simple and practical, easy to install, and can effectively improve construction efficiency, reduce rework costs caused by poor isolation effect, extend the service life of the structure, and enhance the safety and durability of the building structure.

[0024] Example 2: Figure 2 , Figure 3 and Figure 4As shown, an extension rope 6 is fixedly connected to the other end of the connecting band 5. The extension rope 6 is slidably connected to the connecting block 4. The extension rope 6 passes through the connecting block 4 and is bent at ninety degrees before being arranged along the length of the main body 1 of the isolation net. A cavity 8 is provided on the inner side wall of the connecting block 4. The cavity 8 is located on both sides of the connecting band 5. A rubber block 9 is fixedly installed on the inner side wall of the cavity 8. A serrated block 10 is fixedly connected to one end of the rubber block 9. One side of the serrated block 10 is attached to the side of the connecting band 5 and the side of the extension rope 6.

[0025] The overall effect of this embodiment is that one end of the connecting band 5 is fixedly connected by the connecting block 4, and the extension rope 6 at the other end passes through the connecting block 4 and is bent and arranged along the main body 1 of the isolation net to form an adjustable tension structure. When it is necessary to splice or fix the isolation net, the extension rope 6 is pulled to tighten it, which drives the connecting band 5 to tighten towards the connecting block 4. At this time, the rubber block 9 in the inner cavity 8 of the connecting block 4 will push the sawtooth block 10 against it, so that it is close to the side of the connecting band 5 and the extension rope 6. The friction is increased by using the one-way clamping characteristic of the sawtooth, so as to realize the rapid tensioning and fixing of the isolation net.

[0026] Through the linkage mechanism between the extension rope 6 and the serrated locking block 10, the tension of the isolation net can be flexibly adjusted according to the construction scenario, adapting to beam-column joints of different sizes or irregular corners, improving installation efficiency. The buffering effect of the rubber block 9 prevents damage to the connecting strip 5 caused by rigid clamping. The one-way locking function of the serrated locking block 10 ensures that the isolation net remains stable under the lateral pressure of concrete pouring, preventing displacement or loosening, effectively improving isolation accuracy. The adjustable tension structure reduces the cumbersome procedures of traditional binding or welding fixation, saving labor costs, and supports quick disassembly and reuse, reducing material waste. It is suitable for standardized construction and the refined isolation needs of complex joints, ensuring the construction quality and structural integrity at the junction of high and low grade concrete.

[0027] The usage and working principle of this device are as follows: The main body 1 of the isolation net and the extended isolation net 2 are used as the core separating components. The installation and fixation are achieved by the cooperation of the connecting strip 5, the connecting block 4 and the limiting block 7. When in use, the connecting block 4 is put on the connecting strip 5, and the connecting strip 5 is wrapped around the concrete surface. The limiting block 7 is fixed to the corner. The extended isolation net 2 covers the connected structure in the same way to block the lateral flow of concrete. The rubber sleeve 3 at the junction protects the connection part and fills the gap to prevent grout leakage. In the second embodiment, one end of the connecting strip 5 is connected through the connecting block 4, and the other end of the extension rope 6 passes through the connecting block 4 and is bent to form an adjustable tension structure. Pulling the extension rope 6 to make it taut will cause the connecting strip 5 to tighten. During this process, the rubber block 9 in the cavity 8 of the connecting block 4 will continuously press against the sawtooth locking block 10, and use the one-way locking characteristic of the sawtooth to lock the connecting strip 5 and the extension rope 6.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
