Description

Technical Field

[0001] This utility model relates to the field of foundation pit waler technology, specifically a support device for foundation pit walers. Background Technology

[0002] Sheet piles are commonly used construction equipment for foundation pit support. The waler is a steel beam installed on top of the sheet piles, primarily serving to maintain the assembled planar shape of the formwork and connect the formwork to the lifting frame as a whole. In the support system, the stiffness of the waler has a significant impact on the stiffness of the entire support structure. After the sheet piles are installed, internal supports need to be fixed to their inner walls, and walers are installed on these internal supports. However, traditional internal supports are mostly integral structures with fixed lengths. In actual construction, however, the specifications and models of the walers used may differ, making it difficult to install the walers on the internal supports.

[0003] Chinese patent CN201920341126.3 discloses "A Steel Sheet Pile Support Structure for Foundation Pit" (publication number CN210177511U). This device includes two steel sheet pile support components and an inner support disposed between the two steel sheet pile support components. Each steel sheet pile support component includes a steel sheet pile and a waler detachably connected to the steel sheet pile. The two ends of the inner support are detachably connected to the two walers respectively. However, this device has some drawbacks: the distance between the baffle and the support wall is fixed and cannot be adjusted. When the model of the waler at the construction site does not match the distance between the baffle and the support wall, the waler may sway, posing a safety hazard. Utility Model Content

[0004] To address the aforementioned problems of the prior art, this utility model provides a support device for foundation pit walers, which is applicable to different types of walers within a certain range and can firmly clamp the walers, thus improving the applicability of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support device for a foundation pit waler, comprising a hook that can be suspended on a sheet pile, a first support plate fixedly connected to the hook, a second support plate fixedly connected to the first support plate at its left end, a clamping plate hinged to the right end of the second support plate, an adjustment component for driving the clamping plate to rotate provided at the lower end of the clamping plate, and a diagonal brace fixedly connected between the first support plate and the second support plate.

[0006] The above structural design can be applied to different types of walers within a certain range, and can firmly clamp the walers, thus improving the applicability of this device.

[0007] Preferably, a hinge shaft is fixedly connected to the clamping plate, and the hinge shaft is rotatably connected to the right end of the second support plate. The distance from the hinge shaft to the upper end of the clamping plate is less than the distance from the hinge shaft to the lower end of the clamping plate.

[0008] The above structural design makes it easier to clamp the walers.

[0009] Preferably, the upper end of the clamping plate is hinged to an abutment plate, and a rubber pad is fixedly connected to the inner side wall of the abutment plate. The rubber pad is corrugated.

[0010] By adopting the above structural design, the contact area between the upper part of the clamping plate and the waler is increased, and the friction between the contact plate and the waler is increased, which can further clamp the waler and thus further reduce the possibility of the waler swaying.

[0011] Preferably, the adjustment assembly includes a linkage rod hinged at its upper end to the lower end of the clamping plate, a slider hinged to the lower end of the linkage rod, a screw rod rotatably connected at its upper end to the slider rod, and a fixing block threadedly connected to the screw rod. The slider rod is slidably connected to the first support plate, and the fixing block is fixedly connected to the first support plate.

[0012] By using the above structural design, rotating the screw causes the slider to move up and down, thus achieving the rotation of the clamping plate.

[0013] Preferably, the upper end of the screw is a smooth rod, and a chuck is fixedly connected to the upper end of the screw, with the chuck rotatably connected inside the slider.

[0014] With the above structural design, when the screw rotates, the chuck slips inside the slider, which enables the screw to move up and down with the slider.

[0015] Preferably, the hook is fixedly connected to the extension plate, the first support plate has mounting holes for mounting bolts, the extension plate has through holes corresponding to the mounting holes, and multiple through holes are arranged at equal intervals along the length direction of the extension plate.

[0016] The above structural design allows for adjustment of the height of the waler on the sheet piles according to design requirements.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This device is applicable to different types of walers within a certain range and can firmly clamp the walers, improving its applicability and further reducing the possibility of waler swaying; this device can adjust the height of the walers on the sheet piles according to design requirements.

[0020] Figure 2 This is a schematic diagram of the structure of this utility model;

[0021] Figure 3 This utility model Figure 2 A schematic diagram of the structure viewed from the left; Detailed Implementation

[0022] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a support device for foundation pit walers, including a hook 3 that can be suspended on a steel sheet pile, a first support plate 1 fixedly connected to the hook 3, a second support plate 2 fixedly connected to the first support plate 1 at its left end, a clamping plate 4 hinged to the right end of the second support plate 2, an adjustment component for driving the clamping plate 4 to rotate at the lower end of the clamping plate 4, and a diagonal brace 9 fixedly connected between the first support plate 1 and the second support plate 2.

[0023] A hinge shaft 41 is fixedly connected to the clamping plate 4. The hinge shaft 41 is rotatably connected to the right end of the second support plate 2. The distance from the hinge shaft 41 to the upper end of the clamping plate 4 is less than the distance from the hinge shaft 41 to the lower end of the clamping plate 4. Using the lever principle, when the lower end of the clamping plate 4 rotates, the upper end of the clamping plate 4 can rotate towards the waler, thereby firmly pressing the waler and preventing it from moving.

[0024] The upper end of the clamping plate 4 is hinged to the abutment plate 42, and a rubber pad 43 is fixedly connected to the inner side wall of the abutment plate 42. The rubber pad 43 is corrugated.

[0025] The adjustment assembly includes a linkage rod 5 hinged at the lower end of the clamping plate 4, a slider 51 hinged to the lower end of the linkage rod 5, a screw 52 rotatably connected to the upper end of the slider 51, and a fixing block 53 threadedly connected to the screw 52. The slider 51 is slidably connected to the first support plate 1, and the fixing block 53 is fixedly connected to the first support plate 1.

[0026] The upper end of the screw 52 is a smooth rod, and a chuck 55 is fixedly connected to the upper end of the screw 52. The chuck 55 is rotatably connected inside the slider 51. A hexagonal nut-shaped rotating part is fixedly connected to the lower end of the screw 52 so that the operator can use a wrench to assist in rotating the screw 52. When screw 52 rotates in the forward direction, it pushes slider 51 upward. Since the upper end of screw 52 is unthreaded, the chuck 55 at the upper end of screw 52 slips inside slider 51. The linkage rod 5 changes from an inclined state to a horizontal state, the lower end of clamping plate 4 rotates outward, and the upper end of clamping plate 4 rotates inward, thereby allowing the contact plate 42 to press against the waler. When the waler needs to be removed, screw 52 is rotated in the reverse direction. Since chuck 55 is stuck inside slider 51, screw 52 will move slider 51 downward. The linkage rod 5 changes from a horizontal state to an inclined state, the lower end of clamping plate 4 rotates inward, and the upper end of clamping plate 4 rotates outward, thereby allowing the contact plate 42 to move away from the waler, and the operator can remove the waler from the device.

[0027] The hook 3 is fixedly connected to the extension plate 6. The first support plate 1 has mounting holes 61 for mounting bolts. The extension plate 6 has through holes 62 corresponding to the mounting holes 61. Multiple through holes 62 are provided and are arranged at equal intervals along the length direction of the extension plate 6.

[0028] Working principle: First, the worker adjusts the overlap length between the extension plate 6 and the first support plate 1 according to the height of the waler. Then, the worker uses bolts to pass through the mounting holes 61 and 62, and then installs nuts on the bolts to fix the extension plate 6 and the first support plate 1. The device is then suspended from the sheet pile by the hooks 3. The worker then erects the waler on the device. Next, the worker rotates the screw 52 clockwise, and the screw 52 pushes the slider 51 upward. Since the upper end of the screw 52 has no thread, the chuck 55 at the upper end of the screw 52 is engaged with the slider 51. 1. When the internal mechanism slips, the linkage rod 5 changes from an inclined state to a horizontal state, the lower end of the clamping plate 4 rotates outward, and the upper end of the clamping plate 4 rotates inward, thereby allowing the contact plate 42 to press against the waler; when the waler needs to be removed, the screw 52 is rotated in the opposite direction. Since the chuck 55 is stuck inside the slider 51, the screw 52 will move the slider 51 downward, the linkage rod 5 changes from a horizontal state to an inclined state, the lower end of the clamping plate 4 rotates inward, and the upper end of the clamping plate 4 rotates outward, thereby allowing the contact plate 42 to move away from the waler, and the operator can remove the waler from the device.
