Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an adjustable brace of a steel sheet pile cofferdam. Background Art

[0002] In foundation pit projects, steel sheet pile cofferdams are mainly used to form temporary support structures to prevent the collapse of foundation pit walls and ensure safety during construction. Steel sheet pile cofferdams are a structural system composed of steel sheet piles and purlins. They have high strength and good water tightness and can effectively resist the pressure of soil and water. Bracing is an important part of the steel sheet pile cofferdam structure, which can effectively increase the overall stiffness and stability of the steel sheet pile cofferdam and prevent it from deformation or damage under external loads. It plays a vital role in foundation pit projects. It is one of the key reinforcement structures to ensure the stability and safety of the foundation pit.

[0003] However, most of the current steel sheet pile cofferdam supports have the following problems:

[0004] For example, a deep foundation pit support beam structure of geotechnical engineering with publication number CN202023051257.X can play a supporting effect by pushing the foundation pit support beam, but the support length is limited. The width of the steel sheet pile cofferdam used in different construction sites is different, and the support cannot be adjusted according to the size and width of the steel sheet pile cofferdam. Therefore, the user needs to reset the support device every time the foundation pit is constructed, which increases the labor cost of construction and affects construction efficiency; at the same time, a foundation pit support protection device with publication number CN202122198893.3 can play a supporting and anti-slip role through the cooperation of the support plate and anti-slip particles, but the support plate and the anti-slip particles are mostly integrated. The anti-slip particles on the support plate are prone to wear after long-term use, which is easy to affect the support stability during subsequent use, and it is inconvenient to disassemble and replace the support plate with anti-slip pad.

[0005] Therefore, the applicant has made improvements to this problem and proposed an adjustable brace for a steel sheet pile cofferdam. Utility Model Content

[0006] The purpose of the utility model is to solve the existing problems that the support cannot be adjusted according to the size and width of the steel sheet pile cofferdam, and it is inconvenient to disassemble and replace the support plate with the anti-slip pad conveniently.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A steel sheet pile cofferdam adjustable brace comprises a bidirectional threaded rod, a first connecting rod is threadedly connected to the bidirectional threaded rod, a first connecting plate is rotatably connected to the first connecting rod, a second connecting plate is rotatably connected to the first connecting rod, a fixed seat is rotatably connected to the first connecting plate and the second connecting plate, a sleeve plate is fixedly connected to the fixed seat, an extension plate is arranged in the sleeve plate, a first spring is fixedly connected in the extension plate, a limiting plate is fixedly connected to the first spring, a second connecting rod is fixedly connected to the limiting plate, and a pull plate is fixedly connected to the second connecting rod.

[0009] Preferably, a clamping block is fixedly connected to the pull plate, a support tube is fixedly connected to the fixing seat and the extension plate, the first connecting rod is symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the first connecting rod corresponds one-to-one with the second connecting plate through the first connecting plate.

[0010] Preferably, a mounting plate is fixedly connected to the support tube, an anti-slip support plate is provided on the mounting plate, the side end surface of the limiting plate is in contact with the inner side surface of the extension plate, and the second connecting rod is fixedly connected to the center part of one side of the limiting plate.

[0011] Preferably, a protective shell is provided on the mounting plate and the anti-slip support plate, a second spring is fixedly connected inside the protective shell, the length of the second connecting rod is greater than the length of the block, and the support tube is fixedly connected to the center part of one side of the mounting plate.

[0012] Preferably, the other end of the second spring is fixedly connected to a fixing plate, the fixing plate is fixedly connected to a first clamping rod, the second springs are symmetrically distributed on the left and right sides of the protective shell, and the second springs correspond one-to-one with the first clamping rod through the fixing plate.

[0013] Preferably, an extrusion plate is fixedly connected to the fixing plate, a second clamping rod is fixedly connected to the protective shell, a side end surface of the fixing plate is fitted with an inner side surface of the protective shell, and the second clamping rods are equidistantly distributed on the protective shell.

[0014] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0015] 1. The use length of the equipment can be adjusted by setting the extension plate. When in use, the pull plates on both sides of the sleeve plate can be pulled, and the pull plates drive the limit plates to move through the connecting rods. At the same time, the limit plates can squeeze the first springs in the extension plates. While moving, the pull plates can take the card blocks out of the sleeve plates and the extension plates. When the sleeve plates and the extension plates are not hindered by the card blocks, the extension plates can be pushed out of the sleeve plates to adjust the use length, release the pull plates, and drive the second connecting rod and the pull plates on the limit plates to reset under the push of the first spring. The pull plates drive the card blocks to engage in the sleeve plates and the extension plates for limit fixing, and make approximate length adjustment. If there is still a little distance from the steel sheet pile cofferdam and fine adjustment is required, the bidirectional threaded rod can be rotated, and the bidirectional threaded rod drives the first connecting rods on both sides to move inward. At the same time, the first connecting rod pushes the fixing seat to move through the first connecting plate and the second connecting plate, and fine adjustment is made. It can be adjusted and used according to the usage.

[0016] 2. Through the provided protective shell, when the anti-slip support plate on the mounting plate is disassembled and installed, the extrusion plates on both sides of the protective shell can be squeezed, and the extrusion plates drive the fixed plate to move. When the fixed plate moves, the second spring can be squeezed, and at the same time, the fixed plate can separate the first clamping rod from the mounting plate and the anti-slip support plate, and retract it into the protective shell. When the mounting plate and the anti-slip support plate are not affected by the first clamping rod, the protective shell and the second clamping rod can be taken out, and the anti-slip support plate on the mounting plate can be disassembled and replaced to avoid wear of the sliding support plate due to long-term use, which affects the stability of use. The support tube and the extension plate can be disassembled, and the extension plate and the sleeve plate can be disassembled. The damaged part can be replaced according to the usage to improve the stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

The first connecting rod 2 corresponds one-to-one with the second connecting plate 4 through the first connecting plate 3, which can ensure that the fixed seat 5 can be pushed to move and adjust under the cooperation of the first connecting plate 3 and the second connecting plate 4 on both sides.
