Description

Technical Field

[0001] The utility model relates to the technical field of bridge wet joints, in particular to a splicing component of a bridge wet joint construction template. Background Art

[0002] Wet joints refer to the joints between the bridge top plates that are connected into a whole by cast-in-place concrete during the process of prefabricating the prestressed concrete bridge top plates in blocks and cantilevering them into large-span continuous beams. The construction process of wet joints is relatively complicated, but they perform well in terms of tensile structural strength and waterproof performance. They are suitable for bridge construction in coastal areas, areas with abundant rainfall, or other areas with relatively humid natural environments.

[0003] The construction process of wet joints requires formwork and on-site pouring of the joints of the bridge top plate. At this time, the construction formwork needs to be spliced. Among them, steel formwork is widely used in bridge construction projects because of its characteristics of multiple uses and beautiful concrete pouring. At present, most steel formworks are connected with bolts, which makes the installation and disassembly of the formwork more cumbersome, prolonging the construction time and construction efficiency of bridge wet joints. For this reason, we provide splicing components of bridge wet joint construction formwork to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, most of the current steel formworks are connected using bolts, which makes the installation and disassembly of the formwork more complicated, prolonging the construction time and construction efficiency of bridge wet joints. For this reason, this embodiment provides a splicing assembly for bridge wet joint construction formwork.

[0024] See also Figures 1 to 4 This embodiment proposes a splicing assembly for bridge wet joint construction templates, including a template body 1, and a splicing mechanism 2 for splicing bridge wet joint construction templates is arranged outside the template body 1.

[0025] The splicing mechanism 2 includes two symmetrical first plug-in blocks 203 fixed to one side of the template body 1 and a first groove 201 matched therewith, and two symmetrical plug-in rods 202 fixed to the other side of the template body 1 and a second groove 204 matched therewith.

[0026] The two first plug-in blocks 203 are symmetrically fixed on one side of the template body 1 and can be inserted into the first grooves 201 opened on the adjacent template bodies 1 to achieve the connection stability between the two adjacent template bodies 1.

[0027] At the same time, the two plug-in rods 202 are symmetrically fixed to the other side of the template body 1 and can be inserted into the second grooves 204 opened on the adjacent template bodies 1, so as to further achieve the connection stability between the two adjacent template bodies 1.

[0028] The inner wall of the template body 1 is slidably connected with two symmetrical first limit rods 5, which are adapted to the first plug-in block 203. The first limit rods 5 can be inserted into the reserved grooves on the template body 1 and the first plug-in block 203 to limit and fix the first plug-in block 203 inserted into the adjacent template body 1, thereby improving the connection stability between the two template bodies 1.

[0029] The outer surfaces of the two first limit rods 5 are sleeved with second springs 6, and the two first limit rods 5 are respectively fixedly connected to the two second springs 6, and the two second springs 6 are fixedly connected to the template body 1. By setting the second springs 6, the first limit rods 5 can be limited and supported to prevent the first limit rods 5 from slipping out of the reserved groove on the first plug-in block 203.

[0030] Pull the first limiting rod 5 to make it slide in the reserved grooves on the template body 1 and the first plug-in block 203. At the same time, the second spring 6 will be stretched to cause it to produce elastic deformation. When the first limiting rod 5 completely slides out of the reserved groove on the first plug-in block 203, the limiting fixation of the first plug-in block 203 can be released.

[0031] The two first limiting rods 5 are both provided with first pull rings 7 on the side away from the formwork body 1. By providing the first pull rings 7, the first limiting rods 5 can be easily pulled to move, thereby improving the convenience of installing and disassembling the bridge wet joint construction formwork.

[0032] A second plug-in block 3 is fixedly connected to one side of the template body 1 , and a third groove 4 is formed on the other side of the template body 1 . The second plug-in block 3 is matched with the third groove 4 .

[0033] The second plug-in block 3 is fixed at the center of one side of the formwork body 1 and can be inserted into the third groove 4 opened on the adjacent formwork body 1, so as to connect two adjacent bridge wet joint construction formworks, further improve the stability of the bridge wet joint construction formworks during connection, and enhance the structural strength of the bridge wet joint construction formworks to prevent deformation.

[0034] Two symmetrical telescopic rods 205 are fixedly connected to the inner walls of the two first plug-in blocks 203. A clamping block 206 is fixedly connected to a side of each telescopic rod 205 away from the first plug-in block 203.

[0035] When the first plug-in block 203 is gradually inserted into the first groove 201 provided on the adjacent template body 1, the clamping block 206 will contact the adjacent template body 1, so that the clamping block 206 is gradually squeezed into the reserved groove provided on the first plug-in block 203, and drives the telescopic rod 205 to retract.

[0036] A first spring 207 is sleeved on the outer surface of each telescopic rod 205 , and the first plug-in block 203 and the clamping block 206 are fixedly connected to the first spring 207 .

[0037] After the block 206 moves, it will compress the first spring 207, causing it to produce elastic deformation. Under the resetting action of the first spring 207, the block 206 will tend to return to its initial position until the first plug-in block 203 is plugged into place. The block 206 can be inserted into the first groove 201, thereby realizing the connection between two adjacent template bodies 1.

[0038] The inner wall of the template body 1 is slidably connected with a second limit rod 8, which is adapted to the second plug-in block 3. The second limit rod 8 can be inserted into the reserved grooves on the template body 1 and the second plug-in block 3 to limit and fix the second plug-in block 3 inserted into the adjacent template body 1, thereby improving the connection stability between the two template bodies 1.

[0039] The outer surface of the second limit rod 8 is sleeved with a third spring 9, and the third spring 9 is fixedly connected to the template body 1. The third spring 9 is fixedly connected to the second limit rod 8. By setting the third spring 9, the second limit rod 8 can be limited and supported to prevent the second limit rod 8 from slipping out of the reserved groove on the second plug-in block 3.

[0040] Pull the second limit rod 8 to make it slide in the reserved grooves on the template body 1 and the second plug-in block 3. At the same time, the third spring 9 will be stretched to cause it to produce elastic deformation. When the second limit rod 8 completely slides out of the reserved groove on the first plug-in block 203, the limit fixation of the first plug-in block 203 can be released.

[0041] A second pull ring 10 is installed on the side of the second limiting rod 8 away from the template body 1. By providing the second pull ring 10, the second limiting rod 8 can be easily pulled to move, thereby improving the convenience of installing and disassembling the bridge wet joint construction template.

[0042] The template body 1, the plug-in rod 202 and the first plug-in block 203 on the same bridge wet joint construction template are connected by welding, thereby improving the structural strength of the bridge wet joint construction template.

[0043] The components in the drawings of the present invention are only for style reference and are not for specific size standards. The specific sizes are determined according to the actual requirements of production. At the same time, the materials of the components can be replaced accordingly according to actual needs.

[0044] Working principle: When supporting the wet joints of the bridge, the splicing components can be used to quickly fix or separate the two adjacent construction templates, align the two adjacent template bodies 1, and then control the two adjacent template bodies 1 to approach each other, so that the first plug-in block 203 is gradually inserted into the first groove 201 opened on the adjacent template body 1, so as to achieve the connection stability between the two adjacent template bodies 1, and the plug-in rod 202 is gradually inserted into the second groove 204 opened on the adjacent template body 1, so as to further achieve the connection stability between the two adjacent template bodies 1. At the same time, when the first plug-in block 203 is gradually inserted into the first groove 201 opened on the adjacent template body 1, the card block 206 will contact the adjacent template body 1, so that the card block 206 is gradually squeezed into the reserved groove opened on the first plug-in block 203, and drives the telescopic rod 205 to contract, and at the same time compresses the first spring 207 to cause it to produce elastic deformation. Under the reset action of the first spring 207, the block 206 will tend to return to the initial position until the first plug-in block 203 is plugged in place, and the block 206 can be inserted into the first groove 201, thereby realizing a stable connection between the two adjacent formwork bodies 1. The spliced ​​bridge wet joint construction formwork is then installed and fixed, and before pouring, the wet joint should be rinsed and fully moistened thirty minutes in advance to ensure good contact between the new and old concrete. At the same time, it should be noted that the bridge wet joint construction formwork cannot be disassembled or the support can be released before the wet joint concrete reaches the designed strength and hardness. After that, after the poured concrete is dry, the bridge wet joint construction formwork can be disassembled, and then the two adjacent formwork bodies 1 are disassembled, and a certain amount of force needs to be applied to complete the disassembly, thereby achieving the goal of shortening the bridge wet joint construction time while meeting the pouring requirements of the bridge wet joint structure, thereby improving the efficiency of the bridge wet joint construction.
