Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically, it relates to a tool for intercepting the pouring of concrete of different grades in the core area of ​​beams and columns. Background Technology

[0002] During construction, beam-column joints are critical load-bearing areas in frame structures, experiencing significant shear forces, bending moments, and axial forces, requiring higher strength and seismic performance. Therefore, high-strength concrete (high grade) is typically used in the core area of ​​the beam-column joint to enhance its load-bearing capacity and ductility. Furthermore, in building structures, beams primarily bear bending loads, while columns primarily bear compressive loads, resulting in different stress characteristics. Columns require higher compressive strength, while beams have relatively lower requirements for concrete compressive strength. Therefore, columns and beams need to use concrete of different grades. At the beam-column core area connection, interception tools are used to intercept the different grades of retarded concrete to prevent surface cracking caused by varying shrinkage rates, thus ensuring the pouring quality of the beam-column core area.

[0003] Currently, the commonly used interception tool is wooden formwork. By cutting the wooden formwork to match the shape of the core connection area of ​​the beam and column, the formwork is fixed at the connection position to intercept the pouring of concrete of different grades. However, when using this interception method, the concrete at the beam-column structural connection where the wooden formwork is located cannot be poured through, resulting in the connection only through steel bars, which seriously affects the connection effect of the core area of ​​the beam and column. At the same time, due to the presence of stirrups and main reinforcement, the installation of wooden formwork is difficult, and it is impossible to promote and standardize its use in engineering.

[0004] In view of this, this utility model proposes a tool for intercepting the pouring of concrete of different grades in the core area of ​​beams and columns, so as to solve the problems existing in the prior art. Utility Model Content

[0043] The following is combined with Figures 1 to 9 This invention describes the structure of the beam and column core area concrete pouring interception tool of different grades.

[0044] A tool for intercepting the pouring of concrete of different grades in the core area of ​​a beam and column is installed on the inner side of the formwork 1 at the connection of the beam and column core area, including a support frame and several interception components 5, wherein:

[0045] The supporting frame is the main frame of the interception tool. It can be detachably installed on the inner side of the template 1 at the connection of the beam and column core area, and passes through the stirrups in the beam and column core area. It is fixedly connected to the stirrups during use, and is used to fix the position of the supporting frame at the connection of the beam and column core area through the stirrups and the external fixing frame.

[0046] The interception component 5 is installed on the support frame and is used to intercept the concrete during the interception process.

[0047] In the above description, during use, the support frame is first installed at the connection of the beam and column core area, and the interception component 5 is installed at the corresponding position of the support frame to form a sheet-like interception mesh to intercept concrete of different grades during the pouring process; at the same time, the interception component 5 can also increase the strength of the support frame during use and prevent the support frame from undergoing large deformation during the concrete pouring process.

[0048] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the main frame includes a mounting plate 3, a fixed interception plate 4, and an adjustable interception plate 10; wherein:

[0049] The mounting plate 3 is a horizontally mounted plate structure, and an adjustment groove 19 is provided on the mounting plate 3 to match the fixed intercepting plate 4.

[0050] The fixed interceptor plate 4 is mounted on the mounting plate 3 by locking nuts 16 and is set through the adjustment groove 19;

[0051] The adjustable interceptor plate 10 is movably disposed at the lower end of the fixed interceptor plate 4 and is threadedly connected to the sleeve 15 disposed at the lower end of the fixed interceptor plate 4.

[0052] In the above description, the mounting plate 3 allows multiple fixed interception plates 4 to be installed on the same horizontal plane, enabling the interception component 5 to be installed on the same cross section; the fixed interception plates 4 and adjustable interception plates 10 are used to fix and install the interception component 5, ensuring that the interception component 5 is located on the same plane to intercept concrete; the fixed interception plates 4 and adjustable interception plates 10 allow the size of the interception cross section of the entire interception tool to be adjusted according to the size of the interception cross section during construction, making it suitable for concrete pouring interception at the connection of beam and column core areas with different cross sections; the adjustment groove 19 allows the spacing of the fixed interception plates 4 to be adjusted as needed during use, so as to meet the installation requirements of different main reinforcement spacings.

[0053] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, an operating handle 2 is also installed on the other side of the mounting plate 3 via a connecting rod 17; in use, the mounting plate 3 is installed and moved by operating the operating handle 2.

[0054] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a threaded connection section is provided at the upper end of the fixed interceptor plate 4. The threaded connection section passes through the adjustment groove 19, and two locking nuts 16 are threadedly connected to the threaded connection section. The two locking nuts 16 are respectively provided on the upper and lower sides of the mounting plate 3 for installing and fixing the fixed interceptor plate 4. At the same time, the installation height of the fixed interceptor plate 4 can also be adjusted by the two matching locking nuts 16 to meet different construction needs.

[0055] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the sleeve 15 is fixedly installed on one side of the lower end of the fixed interceptor plate 4.

[0056] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the interception component 5 includes matching upper and lower interception pieces. The upper interception piece is connected to the fixed interception plate 4, and the lower interception piece is connected to the adjustable interception plate 10. The upper interception piece is installed on the fixed interception plate 4 near the pouring side, and the lower interception piece is installed on the adjustable interception plate 10 away from the pouring side, forming a misaligned space between the upper and lower interception pieces. The docking depth between the upper and lower interception pieces can be adjusted by adjusting the position of the adjustable interception plate 10 to meet the concrete pouring interception requirements at the connection points of beam-column core areas at different elevations.

[0057] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, both the upper and lower interception panels include a hinge plate 6, a pressure plate 8, and an interception mesh 9. The hinge plate 6 is mounted on the fixed interception plate 4 and the adjustable interception plate 10 by mounting bolts 18. The hinge plate 6's leaves cooperate with the fixed interception plate 4 and the adjustable interception plate 10, and after installation, the rotation angle of the hinge plate 6's leaves is limited by the limiting action of the fixed interception plate 4 and the adjustable interception plate 10, preventing it from rotating beyond the plane of the fixed interception plate 4 and the adjustable interception plate 10 under concrete pressure. This affects the interception effect on concrete; the pressure plate 8 is set on both sides of the hinge plate 6 and is fixedly connected to the leaf of the hinge plate 6. The two adjacent pressure plates 8 in the same group are connected through the hinge plate 6; the interception mesh 9 is connected to the pressure plate 8 through the first connecting bolt 13. That is, the interception mesh 9 is connected and fixed through the pressure plate 8, which not only effectively enhances the fixing effect of the interception mesh 9, but also enhances the strength of the interception mesh 9 during use, and avoids the impact of concrete pressure on the structure of the interception mesh 9 during concrete pouring.

[0058] In the above description, by setting two pressure plates 8 in the same group to be installed on the fixed intercepting plate 4 and the adjustable intercepting plate 10 through multiple hinge plates 6, the pressure plates 8 can be rotated to the side away from the fixed intercepting plate 4 and the adjustable intercepting plate 10 during the installation process, avoiding the influence of the main reinforcement on the tool during installation, making the installation process simpler and more convenient.

[0059] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, several matching second positioning bolt holes 11 are provided on the adjustable interceptor plate 10 and its matching pressure plate 8. In use, the adjustable interceptor plate 10 and its matching pressure plate 8 are fixedly connected after installation by using connecting bolts passing through the second positioning bolt holes 11, which avoids the pressure plate 8 on the adjustable interceptor plate 10 from flipping backward and ensures the interception effect of the pressure plate 8 on the adjustable interceptor plate 10 on the concrete during the later pouring.

[0060] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the intercepting mesh 9 is a steel mesh structure with several grids, which allows water in the concrete to pass through while intercepting the concrete aggregate. The specific grid size can be selected according to construction needs and specific concrete grade. At the same time, the grid setting of the intercepting mesh 9 can form a rough surface on the pouring surface, which facilitates the connection of the contact surface when pouring concrete of another grade.

[0061] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, both the fixed interceptor plate 4 and the adjustable interceptor plate 10 are provided with first positioning bolt holes 14 to cooperate with the hinge plate 6, so as to facilitate the installation of the hinge plate 6 on the fixed interceptor plate 4 and the adjustable interceptor plate 10.

[0062] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressure plate of the pressure plate 8 is also provided with a relief opening 12. The relief opening 12 is used in conjunction with the main rib 7. During installation, the relief opening 12 can both allow the position of the main rib 7 to be made available and the main rib 7 can also fix the pressure plate 8.

[0063] The implementation principle of the beam-column core area concrete pouring interception tool of this utility model is as follows: First, the worker installs the support frame at the connection of the beam-column core area, and ensures that the interception component 5 can cover the cross section of the beam-column core area connection after installation by adjusting the installation position of the fixed interception plate 4 and the installation length of the adjustable interception plate 10. Then, the support frame is fixed. After the support frame is fixed, according to the installation and interception requirements, the corresponding size of the pressure plate 8 and the interception mesh 9 are prepared in advance, and the pressure plate 8 and the interception mesh 9 are installed to form a sheet-like interception tool. The position of this interception tool is fixed and positioned. Finally, the concrete is poured, and it is observed whether there is leakage or deformation. Finally, after the concrete solidifies, the interception tool is disassembled and another grade of concrete is poured.

[0064] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
