Technical Field
[0001] This utility model relates to the field of casting formwork reinforcement structure technology, and in particular to a formwork reinforcement structure for casting beam-column joints. Background Technology
[0002] In the field of building construction, beam-column joints are the core load-bearing parts of concrete structures, and their pouring quality directly determines the stability and safety of the overall building structure. Formwork reinforcement structures are key to ensuring the pouring quality of beam-column joints. Reliable sealing and fixing are required to ensure that cement grout does not leak during the pouring process and that the formwork does not shift, ultimately forming a dense and well-formed joint structure. However, existing beam-column joint pouring formwork reinforcement structures generally suffer from poor sealing and easy grout leakage, which not only leads to quality defects such as honeycomb and pitting in the joint concrete, but also increases the cost of later repairs and construction time, making it difficult to meet the requirements of modern buildings for high-precision and high-efficiency construction. Most traditional reinforcement methods use a simple combination of "formwork + timber + steel pipes," which is initially fixed by wire binding or bolts. There is a lack of specialized sealing design between formwork and between formwork and reinforcement components, relying only on the natural fit of the formwork edges for sealing. When cement grout is poured, the grout easily seeps out from the gaps in the formwork joints under pressure, especially at the external corners of beam-column joints, where the stress is concentrated and the seal is weak, resulting in more prominent leakage. This leads to chipped edges and corners of the concrete at the external corners, affecting the structural appearance and load-bearing performance. Although some semi-automatic reinforcement structures add rubber sealing strips, the sealing strips have poor compatibility with the formwork and lack a clamping and fixing mechanism. They are prone to falling off or deforming after long-term use or under the pressure of grout, and the sealing effect rapidly diminishes with the construction process. Therefore, this application designs a formwork reinforcement structure for beam-column joint pouring to solve the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 5This utility model discloses a formwork reinforcement structure for beam-column joint casting, comprising four formwork templates 1 and a joint reinforcement mechanism. The joint reinforcement mechanism consists of four sealing plates 3, a mating frame, and four docking support components. The docking support components are fixedly installed on the side walls of the sealing plates 3. The four sealing plates 3 are arranged around each other and are respectively inserted into the upper end of the mating frame. The mating frame is bolted to the formwork template 1. The upper end of the mating frame is provided with a movable mounting frame, which is fixed to the outside of the four sealing plates 3 with clamps. Multiple reinforcing bars 4 are provided on the inner side of the four formwork templates 1. The four formwork templates 1 construct the foundation chamber for beam-column joint casting, and the joint reinforcement mechanism is connected through the sealing plates. 3. The double seal is formed by the sleeve frame, and the docking support component and the movable installation frame enhance the overall stability, effectively preventing template displacement and grout leakage during pouring, and improving the quality of node pouring and structural safety. The docking support component consists of a connecting block 2, two hinged fixing plates 10 and a connecting sleeve frame. The two hinged fixing plates 10 are rotatably installed on the sealing plate 3. The connecting block 2 is located between the two hinged fixing plates 10 and is fixedly connected to the two hinged fixing plates 10 by bolts. The connecting sleeve frame is slidably installed on the connecting block 2. The hinged fixing plate 10 can rotate around the sealing plate 3 to adjust the angle. It is fixed with the connecting block 2 and bolts, which can realize the docking support of the reinforcement structure installed in a non-right angle position.
[0015] In this utility model, two fixing bolts 5 are symmetrically fixedly installed on the connecting block 2, and a sliding groove is opened on the connecting sleeve frame to cooperate with the fixing bolts 5. A clamping nut is provided on the fixing bolts 5 to press the connecting sleeve frame. The sliding trajectory of the connecting sleeve frame is limited by the cooperation of the fixing bolts 5 and the sliding groove to prevent displacement during support. The clamping nut can lock the position of the connecting sleeve frame to realize the docking support of the two-by-two reinforcement structures. The movable installation frame is composed of four fixed frame plates 8 and four triangular pins 9. The four fixed frame plates 8 are connected and fixedly installed end to end. Multiple rectangular sliding grooves are opened at equal intervals on one end of the fixed frame plates 8, and the triangular pins 9 are inserted into the rectangular sliding grooves. The fixed frame plates 8 can be flexibly adapted to the sealing plate 3 surrounding structure with different circumferences by connecting end to end. The triangular pins 9 are inserted into the rectangular sliding grooves to achieve quick locking. Assembly and disassembly can be completed without complicated tools, which greatly simplifies the operation process and improves the efficiency of template reinforcement construction. The triangular pins 9 can be adjusted by adjusting the position and depth of insertion into the rectangular sliding groove to squeeze the sleeve part of the fixed frame plate 8, eliminate gaps and strengthen the connection and fixation, and ensure the stability of the clamp of the movable installation frame.
[0016] In this invention, a fixing angle plate 7 is installed between the sealing plates 3. Symmetrical limiting grooves 6 are provided on the sealing plates 3 to accommodate the fixing angle plates 7. A fixing bolt passes through the sealing plates 3 and the fixing angle plates 7. The limiting grooves 6 ensure precise alignment between the fixing angle plates 7 and the sealing plates 3. The fixing angle plates 7 strengthen the structural strength of the joint between the sealing plates 3, and the fixing bolts further reinforce the connection, preventing cracking at the joint of the sealing plates 3 due to pouring pressure. This improves the overall sealing performance and pressure resistance of the reinforced structure, preventing leakage at the external corner. The fitting sleeve frame has a limiting sealing groove 12 for the fitting sealing plate 3. A limiting top plate 11 is hinged in the limiting sealing groove 12. A push bolt is threaded through the outer wall of the fitting sleeve frame, and the end of the push bolt abuts against the limiting top plate 11. The limiting sealing groove 12 provides precise insertion and positioning for the sealing plate 3. Rotating the push bolt can push the limiting top plate 11 to tightly press the sealing plate 3, eliminating the gap between the two, effectively blocking the leakage path of cement slurry during pouring, and at the same time enhancing the connection stability between the fitting sleeve frame and the sealing plate 3, avoiding relative displacement between the two during the pouring process.
[0017] Working Principle: When using this invention, the basic frame is first assembled: four mold templates 1 are spliced together to form a beam-column joint pouring chamber. Multiple reinforcing bars 4 are placed inside the chamber according to design requirements, ensuring precise positioning of the reinforcing bars 4 to guarantee the structural strength of the subsequent pouring joints. Then, the mating frame is fixed to the joint connection of the mold template 1 with bolts, creating a seamless connection between the mating frame and the mold template 1, laying the foundation for subsequent sealing and reinforcement. Next, sealing and corner protection are carried out: four sealing plates 3 are respectively inserted into the upper end of the mating frame, ensuring a tight seal. At the splicing corner of the sealing plate 3, align the fixing angle plate 7 with the limiting groove 6 on the sealing plate 3 and insert it to ensure precise fit between the fixing angle plate 7 and the sealing plate 3. Then, insert the fixing bolts to lock them together. This step strengthens the structural strength of the splicing joint of the sealing plate 3 by fixing the angle plate 7, effectively preventing corner cracking and leakage caused by pouring pressure, and improving the overall pressure resistance of the joint reinforcement structure. After that, adjust the docking support components: first, rotate the two hinged fixing plates 10 to match the support angle of the sealing plate 3, and place the connecting block 2 on the two hinged plates. Between the fixed plates 10, the three are fixed with bolts; the sliding connecting frame moves along the fixed bolts 5 and sliding grooves on the connecting block 2, and after adjusting to the required support position, the fastening nuts are tightened to lock the connecting frame; the sliding trajectory is limited by the cooperation of the fixed bolts 5 and the sliding groove to avoid support displacement, realize the stable docking support of adjacent reinforcement structures, and ensure that the sealing plate 3 is subjected to uniform force; finally, the movable installation frame clamp is fixed: the four fixed frame plates 8 are sleeved end to end on the outside of the four sealing plates 3, and the frame plate sleeve length is adjusted according to the circumference of the sealing plate 3; the triangular pins 9 are inserted into the appropriate rectangular sliding groove position, and the fixed frame plates 8 are squeezed to achieve tight locking by controlling the insertion depth and position of the triangular pins 9, and the assembly can be completed without complicated tools; at this time, the movable installation frame forms a ring clamp, which further strengthens the overall stability of the sealing plate 3 and prevents the template from shifting during pouring; at this point, the template reinforcement structure is assembled and cement slurry pouring operation can be carried out. The entire reinforcement system effectively avoids the problems of grout leakage and displacement during pouring through multiple sealing and support designs, and ensures the quality of beam-column joint pouring.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
