Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for intercepting cast-in-place concrete in post-pouring strips. Background Technology

[0002] In building construction, a post-cast strip is a temporary construction joint set up during the construction of cast-in-place reinforced concrete structures to prevent harmful cracks caused by uneven temperature and shrinkage. During the pouring of the post-cast strip concrete, effective interception devices are required to prevent concrete leakage and ensure a clear boundary between the old and new concrete.

[0003] Currently, common methods for intercepting post-pouring strips on construction sites often involve using wire mesh with reinforcing bars for fixation, or using materials like quick-closing mesh. When using wire mesh, fixing it to the reinforcing bars is cumbersome. During concrete pouring, the impact force of the concrete is significant, making the wire mesh prone to deformation or even breakage, leading to concrete leakage and affecting the construction quality of the post-pouring strip. While quick-closing mesh offers some interception effectiveness, it suffers from difficulties in removal after installation, potential damage to surrounding concrete structures during removal, and relatively high material costs. Furthermore, most existing interception devices are single-use and cannot be reused, resulting in resource waste and increased construction costs. Additionally, the traditional structure of interception devices is inconvenient for transportation and storage, and the efficiency of installation and dismantling during construction is low, failing to meet the demands of efficient construction in modern building engineering.

[0004] Therefore, developing a post-cast strip concrete interception device that is simple in structure, easy to install and disassemble, reusable, has a good interception effect, and can ensure construction quality has become an urgent problem to be solved in the construction field. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a device for intercepting cast-in-place concrete in post-pouring strips, so as to solve the problems pointed out in the background art.

[0006] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A post-cast strip concrete interception device includes multiple interception units, each comprising a frame and a filter screen. The frame is rectangular and consists of four side frames, with adjacent side frames connected by a detachable connection structure. The filter screen is fixedly installed within the frame. Multiple interception units are sequentially spliced ​​along the length of the post-cast strip, and the frames of adjacent interception units are detachably connected by a connecting component. The top and bottom of the frame are provided with fixing structures for fixing the interception device to the reinforcing bars on both sides of the post-cast strip.

[0007] Furthermore, the connection structure includes slots and inserts at the ends of the frame. The inserts can be inserted into slots in adjacent frame sections, and both the inserts and slots have corresponding threaded holes. Fastening bolts pass through the threaded holes to securely connect the inserts and slots. This connection method makes the assembly and disassembly of the frame more convenient and faster, facilitates transportation and storage, and ensures the robustness of the frame connection.

[0008] Furthermore, the connecting assembly includes connecting lugs disposed on the side of the frame, and the connecting lugs of two adjacent intercepting units are connected by connecting bolts. Through the connection lugs and connecting bolts, multiple intercepting units can be stably spliced ​​together to form a complete intercepting device, meeting the interception requirements of post-pouring strips of different lengths.

[0009] Furthermore, the fixing structure includes hooks located at the top and bottom of the frame. These hooks can be attached to the reinforcing bars on both sides of the post-pouring strip, and each hook is equipped with a locking bolt for securing it to the reinforcing bar. This fixing structure is simple to install, allowing for quick fixation of the intercepting device to the reinforcing bar. The locking bolts also ensure the stability of the intercepting device during concrete pouring, preventing displacement.

[0010] Furthermore, the filter screen is made of stainless steel wire mesh, with a mesh size smaller than the maximum particle size of the concrete aggregate in the post-pouring strip. Stainless steel wire mesh is characterized by high strength and corrosion resistance, effectively intercepting concrete aggregate, preventing concrete leakage, and ensuring the service life of the interception device.

[0011] Furthermore, the frame's border is made of aluminum alloy. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which not only facilitates installation and handling but also ensures the structural strength and stability of the frame.

[0012] The beneficial effects of this utility model are: 1. The post-cast strip cast-in-place concrete interception device of this utility model, through its detachable connection structure and connecting components, makes the assembly and disassembly of the entire device more convenient, facilitates transportation and storage, and also facilitates installation and dismantling operations during construction, thereby improving construction efficiency.

[0013] 2. The fixing structure using hooks and locking bolts can quickly and firmly fix the interception device to the reinforcing bars on both sides of the post-pouring strip, ensuring the stability of the interception device during the concrete pouring process and effectively preventing concrete leakage.

[0014] 3. The filter screen is made of stainless steel wire mesh, and the frame is made of aluminum alloy material, which improves the strength, corrosion resistance and service life of the interception device, and ensures the interception effect and construction quality.

[0019] like Figure 1-3 As shown, a post-cast strip concrete interception device includes multiple interception units 1. Each interception unit 1 includes a frame 11 and a filter screen 12. The frame 11 is rectangular and consists of four side frames, which are connected to adjacent side frames by a detachable connecting structure 2. The filter screen 12 is fixedly installed inside the frame 11. Multiple interception units 1 are sequentially spliced ​​along the length of the post-cast strip, and the frames 11 of adjacent interception units 1 are detachably connected by a connecting component 3. The top and bottom of the frame 11 are provided with fixing structures 4 for fixing the interception device to the reinforcing bars on both sides of the post-cast strip.

[0020] The connection structure 2 includes a slot 21 and a plug 22 disposed at the end of the frame. The plug 22 can be inserted into the slot 21 of the adjacent frame, and both the plug 22 and the slot 21 are provided with corresponding threaded holes 23. The plug 22 and the slot 21 are fixedly connected by fastening bolts 24 passing through the threaded holes 23. This connection method makes the assembly and disassembly of the frame 11 more convenient and quick, facilitates transportation and storage, and ensures the firmness of the frame 11 connection.

[0021] The connecting component 3 includes connecting ears 31 disposed on the side of the frame 11. The connecting ears 31 of two adjacent intercepting units 1 are connected by connecting bolts 32. During installation, the connecting ears 31 of two adjacent intercepting units 1 are aligned, and then the connecting bolts 32 are passed through the holes on the connecting ears 31 to fix the two intercepting units 1 together, thereby forming a complete interception device to meet the interception requirements of post-pouring strips of different lengths.

[0022] The fixing structure 4 includes hooks 41 located at the top and bottom of the frame 11. The hooks 41 can be hooked onto the reinforcing bars on both sides of the post-pouring strip, and each hook 41 is equipped with a locking bolt 42 for securing it to the reinforcing bars. This fixing structure 4 is simple to install, allowing for quick fixation of the intercepting device to the reinforcing bars. Furthermore, the locking bolts 42 ensure the stability of the intercepting device during concrete pouring, preventing displacement.

[0023] The hook 41 has a U-shaped structure. One side of the open end of the hook 41 is threaded with a locking bolt 42, and the other end is provided with a threaded locking hole. The front end of the locking bolt 42 is threaded into the threaded locking hole.

[0024] The filter screen 12 is made of stainless steel wire mesh, and its mesh size is smaller than the maximum particle size of the concrete aggregate in the post-pouring strip. Stainless steel wire mesh is characterized by high strength and corrosion resistance, effectively intercepting concrete aggregate, preventing concrete leakage, and ensuring the service life of the interception device.

[0025] The frame 11 is made of aluminum alloy. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which not only facilitates installation and transportation but also ensures the structural strength and stability of the frame 11.

[0026] In actual construction, an appropriate number of interception units 1 can be selected and assembled according to the length and width of the post-pouring strip. After installation, the concrete pouring of the post-pouring strip can be carried out. After the concrete pouring is completed, the interception device can be quickly removed by disassembling the fastening bolts 24, connecting bolts 32 and loosening the locking bolts 42. This is convenient and quick, and the disassembled interception device can be reused, reducing construction costs.
