Description

Technical Field

[0001] The utility model belongs to the technical field of construction joint processing devices, and in particular relates to a template for pouring wet joint concrete of a bridge. Background Art

[0002] At present, wet joint concrete pouring is a common construction method in bridge construction. When pouring wet joint concrete, a concrete pouring formwork is needed to be fixed at the bottom of the joint and the two sides of the construction joint to form a mold cavity for pouring, and then concrete is poured into the mold cavity. After the concrete solidifies, the formwork can be removed.

[0003] Existing formworks are mostly made of bamboo plywood, which is prone to deformation during the pouring process. Once deformation occurs, it will affect the pouring quality of the construction joint. In addition, the concrete blocks between the poured construction joints will be bonded to the formwork, making it inconvenient to remove the formwork. If strong pulling is used, the formwork will easily be damaged, affecting its recycling.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0005] The utility model aims to provide a template for pouring wet joint concrete of a bridge, which is used to solve the technical problems in the prior art that the template is easy to deform and difficult to disassemble.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bridge wet joint concrete pouring template, comprising a template body, wherein a reinforcement structure is provided on a side of the template body facing away from the construction joint, so as to ensure that the template body does not deform during the pouring process;

[0008] At least one pushing unit is also provided on the template body. The pushing unit structure has a driving structure and a pushing block. The pushing block is arranged on the side of the template body facing the construction joint, and the driving structure is arranged on the side of the template body facing away from the construction joint to drive the pushing block to approach or move away from the template body for disassembling the template body.

[0009] As a further optimized technical solution, the reinforcement structure includes a plurality of reinforcement ribs arranged in parallel, and the reinforcement ribs are fixedly connected to the template body.

[0010] As a further optimized technical solution, both ends of the two outermost reinforcing ribs are respectively hinged with support rods, and the support rods can be rotated to support different positions of the template body.

[0011] As a further optimized technical solution, a groove is provided on the side of the template body facing the construction joint, and the groove is adapted to the shape of the pushing block.

[0012] As a further optimized technical solution, a screw is fixedly connected to the pushing block, the screw is threadedly connected to the template body, and the driving structure is fixedly connected to a side of the screw away from the pushing block.

[0013] As a further optimized technical solution, the driving structure is a rotating rod, and the axial direction of the rotating rod is perpendicular to the axial direction of the screw rod.

[0014] As a further optimized technical solution, the vertical reinforcing ribs are provided with a plurality of connecting rods, to which anchors are fixedly connected for fixing the formwork body at the construction joint position.

[0015] As a further optimized technical solution, the tie member includes a tie rope, and a tie hook is provided at one end of the tie rope away from the template body.

[0016] As a further optimized technical solution, a protective tube is provided on the outside of the tie rope for removing the tie rope from the construction joint.

[0017] As a further optimized technical solution, the diameter of the protective tube is slightly larger than the diameter of the tie-knot rope, and the tie-knot hook is detachably connected to the tie-knot rope.

[0018] Beneficial effects: By arranging a reinforcement structure on the side of the template body facing away from the construction joint, the reinforcement structure further enhances the bending strength of the template body, thereby making the template body less likely to deform during the pouring process; in addition, by arranging a pushing unit on the template body, when the mold needs to be removed, the position of the pushing block can be changed with the help of the driving structure, so that after the concrete solidifies, the template body can be directly separated from the concrete through the pushing unit, making the demoulding operation more convenient.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] The utility model provides a template for pouring wet joint concrete of a bridge. A reinforcing structure is arranged on the side of the template body facing away from the construction joint to enhance the overall strength of the template body, thereby avoiding deformation during the pouring process and affecting the pouring quality. In addition, a pushing unit is installed on the template body to increase the convenience of demoulding with the help of the pushing unit.

[0030] like Figure 1As shown, the bridge wet joint concrete pouring formwork includes a formwork body 1, and a reinforcement structure is provided on the side of the formwork body 1 facing away from the construction joint 2 to ensure that the formwork body 1 does not deform during the pouring process. A pushing unit is also provided on the formwork body 1 for disassembling the formwork body 1.

[0031] Specifically, Figure 3 As shown, the reinforcement structure includes two parallel reinforcement ribs 5 , which are made of steel pipes and are fixedly connected to the template body 1 by screws 10 .

[0032] Furthermore, in order to ensure that the four corners of the formwork body 1 do not deform, and to reduce the use of steel pipes to increase production costs, support rods 6 are hinged at both ends of the two reinforcing ribs 5, and the specific hinge position is a position close to the length of the support rod 6 from the end of the reinforcing rib 5, so that when the support rod 6 is fully retracted, the support rod 6 can be completely retracted into the range of the formwork body 1. Otherwise, the protruding support rod 6 alone is easily bumped and damaged, and the demand for storage space and transportation space is increased. When in use, according to the deformation of the four angles of the formwork body 1, the position of the support rod 6 is changed by rotating the support rod 6, so as to support different positions of the formwork body 1 to avoid leakage and deformation of concrete.

[0033] In other embodiments, more than two reinforcing ribs 5 may be provided to ensure the strength of the template body 1 . In this case, when the support rods 6 are installed, the support rods 6 are installed on the two outermost reinforcing ribs 5 .

[0034] like Figure 1 , Figure 2 As shown, the pushing unit structure has a driving structure 3 and a pushing block 4. The pushing block 4 is installed on the side of the formwork body 1 facing the construction joint 2, and the driving structure 3 is installed on the side of the formwork body 1 facing away from the construction joint 2 to drive the pushing block 4 to move closer to or away from the formwork body 1, so as to disassemble the formwork body 1.

[0035] Since the pushing block 4 is installed on the side of the formwork body 1 facing the construction joint 2, in order to reduce the influence of the pushing block 4 on the concrete forming, a groove 101 is provided on the side of the formwork body 1 facing the construction joint 2, and the groove 101 is adapted to the shape of the pushing block 4. In this way, during the non-demolding working period, the pushing block 4 shrinks in the groove 101 to ensure the flatness of the working surface of the formwork body 1.

[0036] The push block 4 is fixedly connected with a screw rod 401, which is threadedly connected to the formwork body 1, and the driving structure 3 is fixedly connected to the side of the screw rod 401 away from the push block 4. In this way, the push block 4 can be rotated by operating the screw rod 401 to rotate through the driving structure 3, and the push block 4 can be driven to push the concrete block to perform demoulding operation. In the present utility model, since the thickness of the formwork body 1 is only 15-25cm, only setting the thread on the formwork body 1 to cooperate with the screw rod 401 can easily make the thread on the formwork body 1 invalid. Therefore, in order to extend the service life of the device, a thickening block 9 is fixedly connected to the position where the push block 4 is installed on the formwork body 1 to increase the overall thickness of the position where the thread is opened. The thickening block 9 is installed on the side away from the push block 4, and the thickening block 9 is also threaded.

[0037] In this embodiment, the driving structure 3 is a rotating rod, and the axial direction of the rotating rod is perpendicular to the axial direction of the screw rod 401 .

[0038] Furthermore, if Figure 5 As shown, the vertical reinforcing rib rod 5 is provided with a plurality of connecting rods 7, and the connecting rods 7 are fixedly connected with anchors 8, so as to facilitate the connection of the anchors 8 with equipment such as a fixing frame 12 on the top of the bridge 11 to be connected, thereby fixing the formwork body 1 at the position of the construction joint 2.

[0039] like Figure 4 As shown, the tie member 8 includes a tie rope 801, which is fixed to the connecting rod 7 through a fixing ring 804. A tie hook 802 is provided at one end of the tie rope 801 away from the formwork body 1 for hanging on the fixing frame 12 to ensure the stability of the formwork body 1 during construction.

[0040] Furthermore, a protective tube 803 is provided on the outside of the tie rope 801. When the formwork needs to be removed, compared with the prior art, the tie rope 801 does not need to be cut off and retained in the concrete. The tie rope 801 only needs to be pulled out of the protective tube 803, so that the device can be reused.

[0041] Furthermore, in order to reduce the diameter of the protection tube 803 and reduce the impact of the protection tube 803 on the strength of concrete, the tie hook 802 is detachably connected to the tie rope 801, so that a protection tube 803 with a diameter slightly larger than the diameter of the tie rope 801 can be selected. When removing the mold, the tie hook 802 can be removed from the tie rope 801.

[0042] Specifically, when in use, the formwork body 1 is first placed at the construction joint 2 of the two bridges 11 to be connected, and then the anchor 8 is passed through the construction joint 2 and hung on the fixed frame 12 on the top of the bridge 11 to be connected. After adjusting the support rod 6 to a suitable position, concrete is poured. When the demolding conditions are met, first disconnect the anchor 8 from the fixed frame 12, and then remove the tie hook 802 from the tie rope 801. Then, rotate the rotating rod, and the push block 4 pushes the formwork body 1 to detach from the concrete block to complete the demolding.

[0043] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
