Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-collision wall template. Background Art

[0002] Crash barriers are the walls on both sides of roads and railways in civil engineering. They are mostly used in viaducts, aerial highways, elevated railways, etc. They serve as safety structures on both sides of bridges. Crash barriers are permanent structures that are formed using reinforced concrete and fixed on both sides of the box beam of an elevated bridge or high-speed railway. They are part of the bridge. When pouring the crash barrier, an inner formwork is fixed on the inner side of the concrete box beam, and an outer formwork is set on the edge of the concrete box beam. Bolts are used to pass through the cavity between the inner and outer formworks to fix the inner and outer formworks. When workers tighten or remove the bolts on the outside of the outer formwork, they need to move to the outside of the concrete box beam to perform high-altitude operations, which is very dangerous.

[0006] Preferably, the limiting component includes a first fixing frame, a second fixing frame and a plurality of limiting rods. The first fixing frame is vertically arranged on the top of the inner template and fixedly connected to the inner template. The second fixing frame is perpendicular to the first supporting frame. The bottom of the second fixing frame is fixedly connected to the side of the first supporting frame away from the outer template.

[0011] Compared with the prior art, the utility model has the following beneficial effects: The structure of the utility model is simple, and the opening and closing are realized by driving the rotation angle of the outer template. Steel structures will be pre-set at the positions where anti-collision walls are arranged on the concrete box girder. Then, the staff will adjust the included angle between the outer template and the inner template. During work, a crane or a forklift is used to move the grinding plate as a whole downward from above the steel structure. After the bottom of the inner template contacts and is fixed to the concrete box girder, the outer template is rotated to a state where the bottom plate abuts against the concrete box girder. Then, a limiting component is used at the top of the inner template and the outer template to prevent the outer template from retracting. Then, baffles are installed on the sides of the outer template and the inner template, and pouring can be carried out. When disassembling the outer template, the limiting component is removed, so that the bottom plate at the bottom of the outer template rotates outward to the anti-collision wall, and the inner template and the outer template can be lifted. Therefore, the utility model avoids the need for the staff to move to the outside of the concrete box girder for high-altitude operation and reduces the danger coefficient during construction.

[0016] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0017] As Figure 1 shown, an embodiment of the present utility model provides an anti-collision wall formwork, which is arranged at the edge of the concrete box girder 12 and includes an inner formwork 1 and an outer formwork 2, and also includes a connecting frame 3, a first support frame 4, a second support frame 5 and a limiting component. The connecting frame 3, the first support frame 4 and the second support frame 5 are all rectangular frames. One side of the connecting frame 3 is fixedly connected to the top of the inner formwork 1, and the other side of the connecting frame 3 is rotatably connected to the top of the outer formwork 2. A passage for construction workers to pour concrete between the inner formwork 1 and the outer formwork 2 is arranged inside the connecting frame 3. A number of connecting rods are arranged at intervals horizontally in the connecting frame 3. During construction, pour into the chamber between the inner formwork 1 and the outer formwork 2 from the intervals between the connecting rods. The first support frame 4 is perpendicular to the outer formwork 2 and is arranged on the outside of the outer formwork 2. One side of the first support frame 4 is fixedly connected to the top of the outer formwork 2. The upper side of the second support frame 5 is fixedly connected to the side of the first support frame 4 away from the outer formwork 2, and the lower side of the second support frame 5 is fixedly connected to the bottom of the outer formwork 2. A bottom plate 13 perpendicular to the outer formwork 2 is fixedly arranged at the bottom of the outer formwork 2, and the side of the bottom plate 13 abuts against the concrete box girder 12. The bottom plate 13 prevents concrete from leaking out of the chamber between the inner formwork 1 and the outer formwork 2. The limiting component is fixedly connected to the top of the inner formwork 1 and the side of the first support frame 4 away from the outer formwork 2. The limiting component is used to keep the outer formwork 2 in a fixed state after rotating downward until the bottom plate 13 abuts against the concrete box girder 12. When concrete is filled between the inner formwork 1 and the outer formwork 2, an outward extrusion force will be applied to the bottom of the outer formwork 2, and the limiting component plays a role in preventing the outer formwork 2 from rotating. A pull rod 11 connected to the concrete box girder 12 is arranged on the outside of the inner formwork 1. The pull rod 11 is used to better fix the inner formwork 1 and the concrete box girder 12. One end of the pull rod 11 is fixedly connected to the concrete box girder 12 using an expansion screw, and the other end of the pull rod 11 is connected to the inner formwork 1 using a hook. Side baffles are arranged on both sides of the cavity formed by the inner formwork 1 and the outer formwork 2 to prevent concrete from leaking from the side. The second support frame 5 and the outer formwork 2 are connected by screws. When there is a completed anti-collision wall on the side of the cavity formed by the inner formwork 1 and the outer formwork 2, a side baffle is arranged on one side of the cavity.

[0018] As shown Figure 3 In this embodiment, as shown, a number of first connecting sleeves 17 are fixedly arranged at intervals on the top of the outer formwork 2 in sequence, and the first support frame 4 is fixedly connected to the first connecting sleeve 17. A second connecting sleeve 18 is arranged on the side of the connecting frame 3, and the second connecting sleeve 18 is located at the interval of the first connecting sleeve 17 and is coaxial with the first connecting sleeve 17. A rotating shaft 19 is arranged in the first connecting sleeve 17 and the second connecting sleeve 18 for disassembly. The connecting frame 3 and the inner formwork 1 are connected by screws.

[0019] As shown Figure 2 In this embodiment, preferably, the limiting assembly includes a first fixing frame 6, a second fixing frame 7 and a number of limiting rods 14. The first fixing frame 6 is vertically arranged on the top of the inner formwork 1 and is fixedly connected to the inner formwork 1. The second fixing frame 7 is perpendicular to the first support frame 4. The bottom of the second fixing frame 7 is fixedly connected to the side of the first support frame 4 away from the outer formwork 2. A number of groups of installation grooves 16 are arranged at intervals on the top of the opposite sides of the first fixing frame 6 and the second fixing frame 7. The two ends of the limiting rod 14 are engaged with the installation grooves 16. In this embodiment, the second fixing frame 7 and the second support frame 5 are integrally formed. When the limiting rod 14 abuts against the second fixing frame 7 and rotates, the integrally formed structure avoids damage to the connection part between the second fixing frame 7 and the second support frame 5 and ensures the structural strength. The staff places the limiting rod 14 horizontally and then moves it downward from top to bottom so that the two ends of the limiting rod 14 move into the installation grooves 16.

[0020] Preferably, hollow steel pipes 15 are fixedly arranged on both sides of the top of the outer formwork 2. The bottom of the hollow steel pipe 15 is welded to the outer wall of the top of the outer formwork 2. When it is necessary to separate the outer formwork 2 from the anti-collision wall, a crowbar can be inserted into the hollow steel pipe 15 to pry it, so that the bottom plate 13 moves away from the anti-collision wall, avoiding the influence of the bottom plate 13 on the movement when the inner formwork 1 and the outer formwork 2 are removed. When removing the inner formwork 1 and the outer formwork 2, the side baffle needs to be removed first. The outside of the side baffle is abutted against the inner formwork 1 and the outer formwork 2 by a jacking rod.

[0021] Preferably, a lifting hole is arranged at the top of the connecting frame 3. One lifting hole is arranged in the middle of the connecting frame 3, or on both sides of the connecting frame 3, so that the inner formwork 1 and the outer formwork 2 keep a balanced state when moving.

[0022] Preferably, a connecting rope is arranged at the top of the hollow steel pipe 15, a hook is arranged at the end of the connecting rope, and a connecting hole for connecting with the hook is arranged on the first fixing frame 6. When the bottom plate 13 rotates to the outside of the anti-collision wall, the hook and the connecting hole are connected, and the included angle between the inner formwork 1 and the outer formwork 2 remains fixed, and the bottom will not collide with the anti-collision wall when moving upward. The connecting rope is made of steel wire.

[0023] Preferably, the limiting rod 14 includes a fixed sleeve 8 and a screw rod 9, and the fixed sleeve 8 is threadedly connected to the screw rod 9. A rotating rod 10 is fixedly arranged on the screw rod 9, and the rotating rod 10 is perpendicular to the screw rod 9. A square limiting block is fixedly arranged at the end of the fixed sleeve 8, and the square limiting block is adapted to the installation groove 16. The two ends of the fixed sleeve 8 and the screw rod 9 away from each other are respectively connected to the installation grooves 16 on the first fixing frame 6 and the second fixing frame 7. During use, only the limiting rod 14 needs to be adjusted to an appropriate length so that both ends of the limiting rod 14 can abut against the installation groove 16. When it is necessary to adjust the length of the limiting rod 14, rotate the rotating rod 10 to make the rotating rod 10 and the screw rod 9 rotate relative to each other. The square groove enables the fixed sleeve 8 not to rotate when the rotating rod 10 rotates.
