Technical Field

[0001] This utility model belongs to the field of concrete construction technology, specifically a formwork structure for large-volume concrete construction joints. Background Technology

[0002] Mass concrete refers to large-volume concrete with a minimum geometric dimension of not less than 1m. During the pouring of mass concrete, it is poured in sections due to design requirements or construction needs. The joint formed between the concrete poured first and later is called a construction joint. Formwork needs to be set up at the construction joint for support and limitation to facilitate subsequent concrete pouring.

[0003] Meanwhile, the patent specification with application number CN220352826U discloses a construction assembly structure for large-volume concrete, "including a supporting formwork, a base slab, and a mixed structural layer: the base slab is made by directly pouring concrete into the bottom of the foundation pit; the mixed structural layer consists of multiple layers from bottom to top, all located on the base slab, and each mixed structural layer is made by further pouring and covering concrete with multiple upper closed cylindrical hollow precast pipe sections arranged within that layer; the supporting formwork is erected around the foundation pit, providing support for the pouring of the mixed structural layer together with the side walls around the foundation pit. This utility model's construction assembly structure for large-volume concrete reduces the amount of concrete used, saving costs; it also reduces the internal heat of hydration of the overall large-volume concrete, thereby reducing the possibility of temperature stress causing cracks in the large-volume concrete."

[0004] Existing construction joint formwork is made according to the scope of concrete pouring. However, when facing large-scale concrete construction, the requirements for the use of construction joint formwork are high and the production is inconvenient. At the same time, the formwork is composed of separate plates and supporting components, which is complex in structure and inconvenient to carry, use and store.

[0005] Therefore, a formwork structure for large-volume concrete construction joints is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a large-volume concrete construction joint formwork structure, which features an integrated formwork, making the formwork and support components non-detachable. The support components are angle-adjustable, facilitating the carrying, use, and storage of the formwork. Furthermore, it includes connecting components for connecting and fixing adjacent formwork sections, allowing the formwork to be assembled according to construction requirements, thus reducing the usage requirements of the construction joint formwork.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-volume concrete construction joint template structure, comprising a plate body, a pair of fixed seats fixedly connected to the upper part of the middle of the plate body, and connecting mechanisms provided at both the upper and lower ends of the plate body, a support sleeve movably connected to the middle of the fixed seats, an adjusting rod threadedly connected to the lower part of the support sleeve, a base movably connected to the bottom of the adjusting rod, a positioning screw threadedly connected to the inside of the base, a limit ring fixedly connected to the middle of the positioning screw, and the connecting mechanism comprising a fixed block and a snap-fit ​​ring, a connecting frame provided on the outer side of the opposite surfaces of the fixed block and the snap-fit ​​ring, and a hexagonal nut threadedly connected to one end of the snap-fit ​​ring on the outer side.

[0008] Preferably, both the support sleeve and the adjusting rod are T-shaped, and the horizontal position of the support sleeve and the horizontal position of the adjusting rod are provided with movable grooves.

[0009] Preferably, the bottom end of the positioning screw penetrates the bottom surface of the base, and the top end of the positioning screw penetrates the top surface of the base and is fixedly connected to a handwheel.

[0010] Preferably, the limiting ring is located inside the upper part of the base, and the limiting ring is movably connected to the base.

[0011] Preferably, the fixing block and the snap-fit ​​ring are fixedly connected to both sides of the plate body, and both the fixing block and the snap-fit ​​ring are located at the top corner of the plate body.

[0012] Preferably, one end of the connecting frame is movably connected to the fixing block, and the other end of the connecting frame is snapped into the snap ring.

[0013] Preferably, the inner side of the hexagonal nut is in contact with the outer surface of the other end of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a fixed base and an adjusting rod to adjust the angle of the base. The adjusting rod, in conjunction with a threaded support sleeve, can adjust the position of the base so that it fits against the support surface. Then, it is fixed by a positioning screw to complete the installation of the panel. This makes the panel and the support components non-removable, and the angle of the support components can be adjusted, which is convenient for carrying, using and storing the template.

[0016] 2. This utility model sets up a connecting mechanism to make the sides of two adjacent plates fit together. Then, the connecting frame is rotated outward by the fixing block so that the other end of the connecting frame is engaged with the adjacent snap ring. Finally, the hexagonal nut is rotated to connect with the snap ring threadedly, so that the inner side of the hexagonal nut fits with the outer surface of the other end of the connecting frame, which plays a fixing role in the connecting frame. This completes the assembly and fixing of the plates, allowing the template to be assembled according to construction requirements, reducing the usage requirements of construction joint templates.

[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a large-volume concrete construction joint template structure, including a plate 1. A pair of fixed seats 2 are fixedly connected to the upper part of the middle of the plate 1, and a connecting mechanism 3 is provided at both the upper and lower ends of the plate 1. A support sleeve 4 is movably connected to the middle of the fixed seat 2. An adjusting rod 5 is threadedly connected to the lower part of the support sleeve 4. A base 6 is movably connected to the bottom of the adjusting rod 5. A positioning screw 7 is threadedly connected inside the base 6. A limit ring 8 is fixedly connected to the middle of the positioning screw 7.

[0024] The connecting mechanism 3 includes a fixing block 9 and a snap ring 11. A connecting frame 10 is provided on the outer side of the opposite face of the fixing block 9 and the snap ring 11, and a hexagonal nut 12 is threaded to one end of the snap ring 11 on the outer side. The connecting mechanism 3 is provided in order to enable the assembly of the template according to the pouring area.

[0025] Specifically, both the support sleeve 4 and the adjusting rod 5 are T-shaped, and the horizontal position of the support sleeve 4 and the horizontal position of the adjusting rod 5 are provided with movable grooves. The plate 1 is placed in the construction joint, and then the support sleeve 4 and the adjusting rod 5 are adjusted by rotating the fixed seat 2, and then the angle of the base 6 is adjusted so that the bottom surface of the base 6 is flush with the support surface. At the same time, the adjusting rod 5 is rotated to move the position of the base 6 so that the base 6 fits with the support surface.

[0026] like Figures 1 to 4 As shown, the bottom end of the positioning screw 7 penetrates the bottom surface of the base 6, and the top end of the positioning screw 7 penetrates the top surface of the base 6 and is fixedly connected to a handwheel. The handwheel drives the positioning screw 7 to rotate, so that the bottom end of the positioning screw 7 is inserted into the support surface, thus completing the installation and fixing of the plate 1.

[0027] Furthermore, the limiting ring 8 is located inside the upper part of the base 6, and the limiting ring 8 is movably connected to the base 6. The limiting ring 8 limits the movement range of the positioning screw 7 to prevent it from separating from the base 6.

[0028] like Figures 1 to 4 As shown, the fixing block 9 and the snap ring 11 are fixedly connected to the two sides of the plate 1 respectively. The fixing block 9 and the snap ring 11 are both located at the top corner of the plate 1. Then, the remaining plates 1 are installed in sequence so that the sides of two adjacent plates 1 are in contact. Then, the connecting frame 10 is rotated outward through the fixing block 9.

[0029] It is worth noting that one end of the connecting frame 10 is movably connected to the fixing block 9, and the other end of the connecting frame 10 is snapped into the snap ring 11, so that the other end of the connecting frame 10 is snapped into the adjacent snap ring 11.

[0030] like Figures 1 to 4 As shown, the inner side of the hexagonal nut 12 is in contact with the outer surface of the other end of the connecting frame 10. Finally, the hexagonal nut 12 is rotated to connect with the snap ring 11, so that the inner side of the hexagonal nut 12 is in contact with the outer surface of the other end of the connecting frame 10, which fixes the connecting frame 10 and completes the assembly and fixation of the adjacent plates 1.

[0031] Working principle and process: In use, the first plate 1 is placed at one end of the construction joint. Then, the support sleeve 4 is rotated by the fixed seat 2 and the adjustment rod 5 is adjusted. The angle of the base 6 is then adjusted so that the bottom surface of the base 6 is flush with the support surface. At the same time, the adjustment rod 5 is rotated to move the base 6 so that the base 6 is in contact with the support surface. Then, the positioning screw 7 is rotated by the handwheel so that the bottom end of the positioning screw 7 is inserted into the support surface, completing the installation and fixing of the plate 1. Then, the remaining plates 1 are installed according to the scope of the concrete pouring construction, so that the sides of the two adjacent plates 1 are in contact. Then, the connecting frame 10 is rotated outward by the fixing block 9 so that the other end of the connecting frame 10 is engaged with the adjacent snap ring 11. Finally, the hexagonal nut 12 is rotated to connect with the snap ring 11 by thread, so that the inner side of the hexagonal nut 12 is in contact with the outer surface of the other end of the connecting frame 10, which fixes the connecting frame 10 and completes the assembly and fixing of the plate 1, thus limiting the construction joint of the concrete.
