Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a connection locking device for bridge templates. Background Art

[0002] Bridge formwork is a steel formwork specially used for building railway or highway bridges, expressways or high-speed railways. It is widely used in bridge construction projects because it can be used multiple times and has beautiful concrete casting.

[0003] In order to ensure the stability of the bridge formwork structure, some connecting locking devices are needed to clamp and fix the bridge formwork during the construction process. However, the commonly used locking devices have the following problems in actual use:

[0004] First, the clamping angle of the clamping plate on the locking device is fixed, usually set straight up or straight down, with low adjustability, which can easily affect the contact area between the clamping plate and the bridge formwork, thereby reducing the clamping force;

[0005] In addition, the locking device is a repeatable device, but after a period of use, especially under a long-term stress state, the internal structure of the device is prone to get stuck, making it difficult to remove. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a connection locking device for bridge formwork, which overcomes the deficiencies of the prior art and effectively solves the problems of low adjustability of angle fixing of clamping plates and great difficulty in removal.

[0009] A screw is screwed on the inner wall of one of the mounting seats, and a rotating sleeve is rotatably connected to the outer wall of one end of the screw. A fixing piece is welded to the outer wall of one end of the track frame, and a tightening knob is screwed on the inner wall of one side of the rotating sleeve.

[0010] Preferably, a latch is slidably connected to the inner wall of the locking clamp, and the latch is arranged on the inner wall of the mounting seat through, and an R-shaped elastic pin is clamped on the inner wall of one end of the latch.

[0011] Preferably, an end block is welded to the outer wall of the other end of the screw rod, and an inner hexagonal groove is provided on the outer wall of one side of the end block.

[0012] Preferably, an inner groove is formed at the bottom of the inner wall of the track frame, and one of the mounting seats is slidably connected to the inner wall of the inner groove.

[0014] Preferably, one of the mounting seats is slidably connected to the inner wall of the track frame, and the other mounting seat is welded to the inner wall of the track frame.

[0015] The beneficial effects of the utility model are:

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1, refer to Figure 1-2 A connection and locking device for a bridge formwork comprises a track frame 1, wherein a symmetrically distributed mounting seat 2 is arranged inside the track frame 1, and a locking clamp 3 is rotatably connected to the top of the inner wall of the mounting seat 2, a screw 4 is welded to the bottom of the outer wall of one side of the locking clamp 3, and a nut 5 is screwed to the outer wall of the screw 4, and a washer 6 is placed between the locking clamp 3 and the nut 5.

[0024] In this embodiment, during the process of loosening the nut 5, the locking clamp 3 can rotate along the axis of the mounting base 2, and the angle between the two locking clamps 3 can be adjusted according to the installation angle of the bridge formwork. It has high flexibility, maximizes the fit between the locking clamp 3 and the bridge formwork, increases the force-bearing area between the two, and thus increases the clamping force of the device.

[0025] Example 2, refer to Figure 3 A connection and locking device for a bridge formwork, wherein a screw rod 7 is screwed onto the inner wall of a mounting seat 2, and a rotating sleeve 8 is rotatably connected to the outer wall of one end of the screw rod 7, a fixing piece 9 is welded to the outer wall of one end of a track frame 1, and a tightening knob 10 is screwed onto the inner wall of one side of the rotating sleeve 8.

[0026] In this embodiment, after unscrewing the tightening knob 10, the rotating sleeve 8 can be removed from the track frame 1 together with the screw rod 7, thereby increasing the distance between the two locking clamps 3 and facilitating the removal of the connecting locking device from the bridge formwork, thereby avoiding the situation in which the mounting base 2 is stuck and the connecting locking device cannot be removed.

[0027] Reference Figure 2 A latch 11 is slidably connected to the inner wall of the locking clamp 3 , and the latch 11 is arranged on the inner wall of the mounting seat 2 , and an R-shaped elastic pin 12 is clamped on the inner wall of one end of the latch 11 .

[0028] Reference Figure 3 A terminal block 13 is welded to the outer wall of the other end of the screw rod 7, and a hexagonal groove 14 is opened on the outer wall of one side of the terminal block 13.

[0029] Reference Figure 3 An inner groove 15 is formed at the bottom of the inner wall of the track frame 1 , and one of the mounting seats 2 is slidably connected to the inner wall of the inner groove 15 .

[0030] Reference Figure 1 A handle 16 is welded to the outer wall of the bottom of the track frame 1.

[0031] Reference Figure 1 One of the mounting seats 2 is slidably connected to the inner wall of the track frame 1, and the other mounting seat 2 is welded to the inner wall of the track frame 1.

[0032] Working principle: before clamping the bridge template, the operator first holds the handle 16 to lift the device to the bottom of the bridge template, and adjusts the position to set the bridge template between the two locking clamps 3. Since the locking clamp 3 can rotate along the axis of the mounting seat 2, the angle between the two locking clamps 3 can be adjusted according to the installation angle of the bridge template. After determining the angle, tighten the nut 5. Finally, the hexagonal drill bit of the electric drill can be combined with the hexagonal groove 14 of the end block 13. Rotating the screw 7 can drive one of the mounting seats 2 close to the other mounting seat 2, so that the two locking clamps 3 tightly clamp the bridge template;

[0033] In order to reuse the device, when removing the connecting locking device, if the mounting base 2 is stuck and the connecting locking device cannot be removed, the tightening knob 10 can be unscrewed first, and the rotating sleeve 8 can be removed from the track frame 1 together with the screw rod 7, thereby expanding the distance between the two locking clamps 3. As the gap between the locking clamps 3 and the bridge formwork increases, the device will be easily removed.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
