Description

Technical Field

[0001] This utility model relates to the field of bridge formwork technology, specifically a connection and locking device for bridge formwork. Background Technology

[0002] Bridge formwork is divided into highway bridge formwork and railway bridge formwork. Depending on the conditions, bridge formwork can also be divided into single and double-cell box girders (large box girders and small box girders), pier columns, pier column formwork, abutments, cap beams, T-shaped bridge formwork, etc. Bridge formwork is assembled into a whole by assembling a series of modules. Traditional bridge formwork splicing operations are complicated, and the spliced ​​parts are relatively loose and not strong enough, making them prone to shaking.

[0003] A search revealed a Chinese patent (publication number: CN218712259U) that discloses a bridge template connection and locking device. The device connects two spliced ​​bridge templates together using a connecting frame and uses a fastening cover to connect the connecting frame to the connection and locking device. The above device uses a large number of bolts to fix each other, which not only makes the assembly time long but also results in low installation efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a bridge template connection and locking device, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bridge template connection and locking device, comprising a splicing bridge template, one end of which is provided with an insertion tube connected thereto, and a first connector provided on the splicing bridge template near the other end, and a second connector corresponding to the first connector provided on the splicing bridge template. When two splicing bridge templates are assembled together, the first connector passes through the insertion tube and connects to the second connector.

[0008] Furthermore, the first connector includes a fixing plate fixedly connected to the spliced ​​bridge template, and multiple threaded rods are fixedly connected to the fixing plate.

[0009] Furthermore, the end of the insertion tube has an insertion hole that corresponds to the threaded rod and through which the threaded rod can pass.

[0010] Furthermore, the second connector includes a fixing bolt with a nut mounted on it, and the nut is threadedly connected to the threaded rod.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the present invention provides a connection and locking device for bridge templates, which has the following advantages:

[0013] Compared to traditional bridge formwork splicing and some existing connection and locking devices that use numerous bolts for assembly, this new connection and locking device is much simpler to operate. Simply insert one end of one spliced ​​bridge formwork into another spliced ​​bridge formwork with a insert tube, allowing the threaded rod of the first connector to pass through the insert tube. Then, by rotating the nut on the second connector to connect with the threaded rod and tightening it, the two spliced ​​bridge formworks are locked and fixed. The entire process is clear and convenient, eliminating the need to spend a lot of time tightening numerous bolts individually, effectively shortening assembly time and significantly improving the installation efficiency of bridge formwork. Especially in large-scale bridge projects requiring the assembly of numerous bridge formworks, it can accelerate construction progress and reduce manpower input. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 The present invention discloses a bridge template connection and locking device, comprising a splicing bridge template 1, which is in the shape of a square tube. A tube 2 is fixedly connected to one end of the splicing bridge template 1 and communicates with it. A first connector 3 is provided on the outer wall of the splicing bridge template 1 near the other end. A second connector 5 corresponding to the first connector 3 is provided on the splicing bridge template 1. When two splicing bridge templates 1 are assembled together, one splicing bridge template 1 is inserted into the tube 2 connected to the other splicing bridge template 1, and the first connector 3 penetrates the tube 2, so that the first connector 3 and the second connector 5 are connected.

[0019] This allows the two spliced ​​bridge templates 1 to be fixedly connected to each other, simplifying the operation.

[0020] The first connecting member 3 includes a fixing plate 8 fixedly connected to the spliced ​​bridge template 1. The fixing plate 8 is welded to the spliced ​​bridge template 1 in a ring shape. Multiple threaded rods 9 are fixedly connected to the fixing plate 8, and the threaded rods 9 are arranged along the length direction of the spliced ​​bridge template 1.

[0021] The end of the insertion tube 2 has an insertion hole 4 that corresponds to and allows the threaded rod 9 to pass through. When the two spliced ​​bridge templates 1 are assembled together, the threaded rod 9 passes through the insertion hole 4, so that the two spliced ​​bridge templates 1 are interlocked at both ends.

[0022] The second connecting member 5 includes a fixing bolt 6, on which a nut 7 is installed, and the nut 7 is threadedly connected to the threaded rod 9. After the two spliced ​​bridge templates 1 are inserted into each other, the nut 7 is rotated on the fixing bolt 6 so that the nut 7 enters the threaded rod 9, and the two spliced ​​bridge templates 1 are pulled and fixed together by one side of the fixing plate 8.

[0023] In summary, when multiple spliced ​​bridge templates 11 are assembled together, the connecting and locking device of this bridge template is used in sequence so that the tail of the spliced ​​bridge template 11 is inserted into the corresponding insertion tube 2 of the spliced ​​bridge template 11. At the same time, the threaded rod 9 passes through the insertion hole 4 and corresponds to the fixing bolt 6. Then, the nut 7 is rotated on the fixing bolt 6 so that the nut 7 enters the threaded rod 9 until the nut 7 is tightened at one end of the insertion tube 2, thereby locking the spliced ​​bridge templates 11 together.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
