Description

Technical Field

[0001] The utility model relates to the technical field of culvert template equipment, more specifically, to a prefabricated culvert oblique cross-shaped wall template Background Art

[0002] With the promotion of green construction, more structures in bridge construction are being prefabricated in factories. The splayed walls of culverts were previously often constructed using wooden formwork or assembled from small steel formwork, a method that has low construction efficiency.

[0003] Therefore, prefabrication is currently used to produce the S-shaped wall formwork, and factory prefabrication construction can better control the quality of concrete and reduce the environmental impact of on-site construction.

[0004] However, during the production process of the current prefabricated S-shaped wall formwork, the workers still knock on the formwork and then remove the formwork. This demolding method can easily cause damage to the prefabricated S-shaped wall. At the same time, the side forms of the S-shaped wall formwork are mainly connected by screw rods. After the concrete solidifies and forms, the workers need to use tools to cut the exposed screw rod heads. The cutting process is time-consuming and labor-intensive, resulting in low demolding efficiency. Utility Model Content

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0022] See Figure 1-Figure 4 As shown, the utility model provides a prefabricated culvert oblique cross-shaped wall formwork, which consists of a first side formwork 1, a second side formwork 2 and a third side formwork 3. The bottoms of the first side formwork 1 and the second side formwork 2 are each provided with a plurality of guide rails 4, and the bottoms of the first side formwork 1 and the second side formwork 2 are respectively slidably connected to the guide rails 4 at corresponding positions, and the guide rails 4 are tilted along the demoulding direction of the first side formwork 1 and the second side formwork 2. The third side formwork 3 is fixedly connected to the first side formwork 1 and the second side formwork 2 by a plurality of telescopic rods 5, and both outer ends of the telescopic rods 5 are detachably installed with external rods 6, and a plurality of pushing mechanisms 7 are installed between the first side formwork 1 and the second side formwork 2 and between the top of the third side formwork 3 and the first side formwork 1 and the second side formwork 2, and a diagonal support rod 31 is detachably installed between the outer side of the third side formwork 3 and the ground.

[0023] In this embodiment, the telescopic rod 5 includes a pull rod 51 and two sleeve rods 52. A socket 53 is provided at one end of the sleeve rod 52. The two ends of the pull rod 51 are respectively inserted into the sockets 53 of the two sleeve rods 52, and the pull rod 51 is detachably connected to the sleeve rod 52 by bolts. Screw holes for inserting bolts are provided on the surface of the sleeve rod 52 at the position of the socket 53. At the same time, a plurality of holes for inserting bolts are evenly provided on the surface of the pull rod 51. By changing the holes at different positions of the pull rod 51 where the bolts are inserted, the overall length of the telescopic rod 5 can be adjusted.

[0024] In this embodiment, the external connecting rod 6 includes a sealing sleeve 61 and a connecting rod 62. The connecting rod 61 is inserted into the sealing sleeve 61. A first threaded column 63 of an integral structure is fixed at one end of the connecting rod 61. A first threaded hole 55 is opened at one end of the sleeve rod 52. The first threaded column 63 is matched with the first threaded hole 55 and connected. A nut 64 is installed at the outer end of the connecting rod 61. The nut 64 is used to fix and lock the sealing sleeve 61 on the outer surface of the first side mold 1, the second side mold 2 or the third side mold 3.

[0025] In this embodiment, the pushing mechanism 7 includes a fixed seat 71, a movable seat 72 and a coupling 73. The fixed seat 71 and the movable seat 72 are respectively provided with a second threaded hole 77 and a ring groove 76 on opposite sides. The coupling 73 is located between the fixed seat 71 and the movable seat 72. Both ends of the coupling 73 are respectively provided with a second threaded column 74 and a turntable 75 of an integral structure. The turntable 75 is movably engaged with the ring groove 76, and the second threaded column 74 is cooperatively connected with the second threaded hole 77.

[0026] When the first side form 1 and the second side form 2 need to be disassembled, it is only necessary to rotate the coupling 73, and the second threaded column 74 of the coupling 73 rotates in the second threaded hole 77 to achieve a change in the distance between the fixed seat 71 and the movable seat 72, thereby pushing the first side form 1 and the second side form 2 away from the concrete surface.

[0027] Furthermore, in order to facilitate the staff to rotate the coupling 73, in this embodiment, a through hole 78 is opened on the surface of the coupling 73. During operation, a crowbar can be inserted into the through hole 78 to easily rotate the coupling 73.

[0028] Furthermore, in order to facilitate the installation work of the staff, in this embodiment, a construction platform 8 is fixedly installed on the outer sides of the first side form 1, the second side form 2 and the third side form 3, and the construction platform 8 is a steel grid structure.

[0029] The specific operation steps are as follows: When assembling the formwork, it is only necessary to adjust the length of the telescopic rod 5 so that the telescopic rod 5 can match the spacing between the first side form 1, the second side form 2 and the third side form 3, and then install the external rod 6 on the outer end of the telescopic rod 5. The first side form 1, the second side form 2 and the third side form 3 can be assembled into an "eight-shaped" wall formwork, and then concrete can be poured into the "eight-shaped" wall formwork;

[0030] After the concrete is solidified and formed, the external rod 6 is removed from the outer end of the telescopic rod 5, and then the first side form 1, the second side form 2 and the third side form 3 are pushed by the pushing mechanism 7. Since the third side form 3 is fixed by the diagonal support rod 31, the upper ends of the first side form 1 and the second side form 2 can be pushed at this time, and the first side form 1 and the second side form 2 can be separated from the concrete surface. At this time, the first side form 1 and the second side form 2 can be moved on the guide rail 4 with little effort to realize the demoulding of the first side form 1 and the second side form 2. After the first side form 1 and the second side form 2 are demoulded, the third side form 3 can be demoulded by manual operation of the staff.

[0031] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, the patent owner may make various variations or modifications within the scope of the appended claims. As long as they do not exceed the scope of protection described by the claims of the present invention, they should be within the scope of protection of the present invention.
