Description

Technical Field

[0001] This utility model relates to the field of building construction formwork technology, specifically a detachable corbel formwork for the top of a masonry structural column. Background Technology

[0002] In masonry structure construction, structural columns are key components for improving the integrity and seismic performance of the walls. Their tops typically require corbel structures to meet load-bearing or connection requirements. In traditional construction, the corbel formwork is usually fixed integrally with the structural column formwork. During concrete pouring, the corbel portion forms simultaneously with the structural column, and the formwork must be completely removed after the concrete has hardened.

[0003] However, this integrated formwork structure has significant drawbacks: on the one hand, to ensure smooth formwork removal, a large amount of concrete pouring allowance is often required at the corbel, leading to serious waste of concrete materials and increased construction costs; on the other hand, the concrete at the connection between the corbel and the structural column is not easily vibrated sufficiently, easily resulting in quality problems such as honeycomb and pitting, affecting structural strength. Furthermore, the overall removal of the formwork can easily cause collision damage to the formed corbel or the top of the structural column, further reducing construction quality.

[0004] Therefore, there is an urgent need for a corbel formwork structure that can save concrete materials, ensure the quality of the top concrete, and is easy to dismantle, in order to solve the problems existing in the current technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable corbel formwork for the top of masonry structural columns. Through modular design, it enables flexible connection and separation of the corbel formwork and the structural column formwork, solving the problems of concrete waste and difficulty in quality control associated with traditional formwork.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable corbel template for masonry structural columns, comprising a structural column template body, corbel template units, pin positioning components, and reinforcing components. The structural column template body is a rectangular frame structure, with a corbel installation notch on one side of its top. The corbel template units are fitted into the corbel installation notch, forming a complete pouring cavity with the structural column template body. The pin positioning components penetrate the connection between the structural column template body and the corbel template units, enabling detachable fixing of both. The reinforcing components are sleeved on the outside of the connection between the structural column template body and the corbel template units, enhancing structural stability during pouring.

[0007] Preferably, the corbel formwork unit includes a support panel, a side baffle, and a connecting ear plate. The support panel is arranged with an inclined structure. One end of the support panel is attached to the outer wall of the main body of the structural column formwork. The side baffle is vertically fixed to both sides of the support panel. The connecting ear plate is integrally formed on the side where the side baffle and the main body of the structural column formwork are connected. The connecting ear plate is provided with positioning holes.

[0008] Preferably, the pin positioning assembly includes a pin rod and a positioning groove. The top of the structural column template body is provided with a positioning groove that matches the connecting ear plate. The connecting ear plate is inserted into the positioning groove. The pin rod passes through the structural column template body, the positioning hole, and the positioning groove.

[0009] Preferably, an operating handle is fixed to the top of the pin rod, and the surface of the operating handle is provided with anti-slip texture to facilitate the insertion and removal operation by construction personnel.

[0010] Preferably, the reinforcement component includes an annular clamp and a fastening bolt. The annular clamp is sleeved on the outside of the main body of the structural column template and the corbel template unit. Both ends of the annular clamp are fixed with connectors, and the fastening bolt passes through the two connectors to achieve fastening.

[0011] Preferably, the inner wall of the main body of the structural column formwork and the upper surface of the supporting panel are coated with a release agent to reduce the adhesion between the concrete and the formwork.

[0012] Preferably, the main body of the structural column template is composed of four template pieces spliced ​​together, and the templates are fixedly connected by mortise and tenon joints.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model achieves quick connection and disassembly with the main body of the structural column formwork by setting up a detachable corbel formwork unit and using a pin positioning component. It eliminates the need to reserve excess concrete pouring allowance, effectively saving concrete materials and reducing construction costs.

[0015] The casting cavity structure formed by the corbel formwork unit and the main formwork of the structural column is regular, which facilitates the compaction of concrete. At the same time, the detachable design avoids collision damage to the formed structure when the whole is dismantled, which significantly improves the concrete quality of the top of the structural column and the corbel part.

[0016] The reinforcement components enhance the stability of the formwork connection during the pouring process and prevent grout leakage; the design of the operating handle and the release agent coating further improves the ease of formwork assembly and disassembly, shortens the construction cycle, and improves construction efficiency.

[0017] The main body of the structural column formwork adopts a spliced ​​structure, and the size of the corbel formwork unit can be customized according to actual needs. It is suitable for the construction of structural columns of different specifications, has strong versatility, and has high practical value. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, this utility model provides a detachable corbel template for the top of a masonry structural column, including a structural column template body 1, a corbel template unit 2, a pin positioning component 3, and a reinforcement component 4;

[0027] The main body 1 of the structural column formwork is a rectangular frame structure, serving as the foundation formwork for the pouring of structural columns. Its dimensions can be adjusted according to the design parameters of the structural columns, exhibiting good versatility. The main body is composed of four formwork panels joined together, with the panels fixedly connected by mortise and tenon joints. This connection method not only ensures the tightness of the formwork joints and effectively prevents grout leakage, but also simplifies the assembly process of the main body, allowing for initial fixing without the need for complex tools. A corbel installation notch 11 is provided on one side of the top of the main body 1 of the structural column formwork. The size of this notch matches that of the corbel formwork unit 2, providing a positioning benchmark for the precise installation of the corbel formwork unit 2.

[0028] The corbel formwork unit 2 is installed at the corbel installation notch 11, forming a complete pouring cavity with the main body of the structural column formwork 1, ensuring that the concrete can be formed according to the design shape. The corbel formwork unit 2 includes a support panel 21, a side baffle 22, and a connecting ear plate 23. The support panel 21 is set with an inclined structure, and its inclination angle can be prefabricated according to the stress requirements of the corbel and the design drawings to ensure the load-bearing performance of the corbel. One end of the support panel 21 is attached to the outer wall of the main body of the structural column formwork 1 to ensure the sealing of the pouring cavity. The side baffle 22 is vertically fixed on both sides of the support panel 21 to block the lateral flow of concrete and ensure the forming quality of the corbel side. The connecting ear plate 23 is integrally formed on the side where the side baffle 22 meets the main body of the structural column formwork 1. The connecting ear plate 23 is provided with a positioning hole 24 to provide support for the installation of the pin positioning component 3, so as to achieve precise docking between the corbel formwork unit 2 and the main body of the structural column formwork 1.

[0029] It should be noted that a detachable reinforcing rod is provided between the supporting panel 21 and the main body of the structural column formwork 1 to further improve the stability of the corbel formwork unit 2.

[0030] Meanwhile, the inner wall of the main body 1 of the structural column formwork and the upper surface of the supporting panel 21 are coated with a release agent. By reducing the adhesion between the concrete and the formwork surface, it not only facilitates the removal of the formwork, but also ensures the flatness of the concrete surface and reduces the amount of repair work in the later stage.

[0031] The pin positioning component 3 passes through the connection between the main body 1 of the structural column template and the corbel template unit 2, and is used to achieve detachable fixing of the two. Its core includes a pin rod 31 and a positioning groove 32. The top of the main body 1 of the structural column template has a positioning groove 32 that matches the connecting ear plate 23. During installation, the connecting ear plate 23 is inserted into the positioning groove 32. The initial positioning is achieved through the cooperation between the groove and the ear plate, ensuring the installation position accuracy of the corbel template unit 2. The pin rod 31 passes through the positioning hole 24 on the main body 1 of the structural column template, the positioning groove 32 on the connecting ear plate 23, and tightly connects the three into one, preventing the corbel template unit 2 from shifting during the pouring process.

[0032] Furthermore, to facilitate operation by construction personnel, an operating handle 33 is fixed to the top of the pin rod 31. The surface of the operating handle 33 is provided with anti-slip texture, which effectively increases the friction between the hand and the operating handle 33, making the insertion and removal operation more labor-saving and convenient, and improving construction efficiency.

[0033] The reinforcing component 4 is fitted onto the outside of the main formwork 1 of the structural column and the corbel formwork unit 2 to enhance the structural stability during pouring and resist the lateral pressure of the concrete. The reinforcing component 4 includes an annular clamp 41 and fastening bolts 42. After the annular clamp 41 is fitted onto the outside of the connection between the two, it can achieve a close-fitting reinforcement. Both ends of the annular clamp 41 are fixed with connectors 43. The fastening bolts 42 pass through the two connectors 43 and are locked with nuts. By adjusting the tightness of the bolts, the clamp pressure can be precisely controlled to ensure the tightness of the connection and effectively prevent grout leakage and formwork deformation.

[0034] It should be noted that the ring clamp 41 is made of aramid material, which has good fit and high wear resistance.

[0035] Working principle and process: First, the four template pieces are assembled into a rectangular frame of the structural column template body 1 using mortise and tenon joints, ensuring a tight fit between the mortise and tenon joints. A bracket installation notch 11 is made on one side of the top of the body according to the bracket design dimensions, and the edges of the notch are sanded smooth. Next, the bracket unit is installed by placing the prefabricated bracket template unit 2 into the bracket installation notch 11, ensuring one end of the supporting panel 21 fits against the outer wall of the structural column template body 1. The side baffle 22 is aligned with the side of the notch. The connecting ear plate 23 is inserted into the pre-set positioning groove 32 of the body to complete the initial positioning. Then, the pin rod 31 is inserted from top to bottom through the positioning hole 24 of the connecting ear plate 23 and the positioning groove 32. The pin is pressed firmly by the operating handle 33 with anti-slip texture to achieve rigid fixation between the two. Then, the ring clamp 41 is put on the outside of the connection between the main body and the corbel formwork unit 2. The position is adjusted so that the connecting parts at both ends of the clamp are aligned. The fastening bolt 42 is inserted and the nut is tightened until the clamp is tightly fitted to the formwork to enhance the resistance to lateral pressure. After completion, preparation for pouring is carried out. The steel reinforcement support mesh 5 is installed in the corbel formwork unit 2 and welded to the main reinforcement of the structural column. The release agent is evenly applied to the inner wall of the main body and the surface of the support panel 21. After the concrete reaches the specified strength, the fastening bolt 42 is loosened to remove the clamp, the pin rod 31 is pulled out, and finally the corbel formwork unit 2 is taken out, cleaned and put into use.
