Description
Technical Field
[0001] The utility model relates to the technical field of post-casting strip template structures, in particular to a post-casting strip template structure capable of preventing slurry leakage. Background Art
[0002] In the field of modern construction engineering, the setting of post-cast strips plays a key role in solving problems of concrete structures caused by temperature and shrinkage imbalances. With the continuous expansion of building scale and the increasing complexity of building structures, the application of post-cast strip formwork has become more and more extensive. Post-cast strips are concrete strips left at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications in order to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to their own uneven shrinkage or settlement. In order to form a post-cast strip, two formworks are generally placed on the supporting floor, and multiple steel bars are inserted between the two formworks. Finally, concrete is poured on the opposite sides of the two formworks.
[0003] However, existing post-cast strip formwork structures use relatively simple splicing methods, such as nailing or bolting. Over long-term use, especially when subjected to high pressure and vibration during concrete pouring, metal bolts are prone to fatigue. With increased use, the strength of the bolts gradually decreases, causing the connection to loosen and slurry to leak from the joints. Furthermore, when securing the formwork, the supporting structure is not stable enough. When the lateral pressure generated by the concrete pouring acts on the formwork, the formwork is prone to displacement, thereby destroying the already loose connection between the formwork and causing frequent slurry leakage. To address this issue, we have provided a post-cast strip formwork structure that is leak-proof. Utility Model Content
[0004] The purpose of the utility model is to provide a post-casting strip template structure that can prevent slurry leakage, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a post-casting strip formwork structure capable of preventing slurry leakage, comprising a plate body, a connecting plate being threadedly connected to the plate body, a bolt passing through the connecting plate, a fixing assembly for improving the stability of the bolt connection being provided inside the connecting plate, and the fixing assembly comprising:
[0006] The fixing column is fixedly installed on the top of the plate body, and the fixing column passes through the connecting plate. A connecting column is fixedly installed inside the fixing column. When the bolt moves upward, it drives the sliding column threaded on its surface to slide upward inside the connecting column. When the sliding column moves upward, it drives the sliding plate fixedly connected on the surface to slide upward on the surface of the connecting column. The sliding column is slidably connected to the inside of the connecting column, and the bolt is threadedly connected to the inside of the sliding column.
[0007] Preferably, a fixed block is fixedly installed on the surface of the connecting column, and a slide plate is fixedly installed on the outside of the sliding column. When the slide plate slides upward, it will contact the movable plate through the connecting rod hinged on its surface, and drive the movable plate to move inside the fixed block away from the center point of the fixed block. One end of the connecting rod is hinged on the surface of the slide plate, and the other end of the connecting rod is hinged on the movable plate. When the movable plate slides, it will also drive the plug plate fixed on the outside of the movable plate to slide in the moving direction of the movable plate, so that the plug plate is plugged into the socket hole opened in the fixed column for fixation, which improves the stability of the bolt during use, improves the fixing effect of the bolt on the template connection, and prevents leakage.
[0008] Preferably, a connecting block is fixedly installed on the outer side of the movable plate, the connecting block is slidably connected to the inside of the fixed block, and an inserting plate is fixedly installed on the outer side of the connecting block.
[0009] Preferably, a fixing ring is fixedly installed on the surface of the sliding column. When the fixing ring moves upward, it will drive the limiting plate and the limiting rod to move upward. When the limiting rod moves upward, it will be inserted into the inside of the positioning ring, thereby limiting the rod for positioning, increasing the friction force of the bolt movement, and reducing the amplitude of the bolt movement, thereby improving the fixation of the bolt. A limiting plate is fixedly installed on the outside of the fixing ring, and a limiting rod is fixedly installed on the top of the limiting plate.
[0010] Preferably, a positioning ring is fixedly installed inside the fixing column.
[0011] Preferably, a sliding groove is provided on the surface of the connecting column, which can drive the slide plate to slide on the surface of the connecting column, a socket is provided on the surface of the fixed column, which can drive the plug plate to pass through the fixed column for restriction, and an annular groove is provided at the bottom of the positioning ring, which can drive the restriction rod to be inserted into the inside of the positioning ring for positioning.
[0012] Compared with the prior art, the present invention provides a post-casting strip template structure that can prevent slurry leakage, which has the following beneficial effects:
[0013] 1. The post-casting strip formwork structure that can prevent leakage of slurry has the setting of fixed components. When in use, the bolts that are under pressure for a long time will slide upward. When the bolts slide, they will drive the sliding column and the sliding plate connected to the outside to move upward. When the sliding plate moves upward, it will drive the plug plate on the outside of the connecting block to penetrate the fixed axis through the connecting rod to limit it, thereby improving the stability of the bolts during use, improving the fixing effect of the bolts on the formwork connection, and preventing leakage.
[0014] 2. The post-casting strip formwork structure that can prevent leakage of slurry has a fixed component. The bolt drives the sliding column to slide upward, which also drives the fixed ring limit plate to move upward. When the limit plate moves upward, it drives the limit rod to be inserted into the inside of the positioning ring, thereby increasing the friction force of the bolt movement and reducing the amplitude of the bolt movement, thereby improving the fixity of the bolt.
