Description

Technical Field

[0001] The utility model relates to the technical field of new flexible structures, in particular to a new flexible structure of prestressed steel supports. Background Technique

[0002] Steel supports refer to using steel pipes, H-shaped steels, angle steels, etc. to enhance the stability of engineering structures. Generally, they are inclined connecting members, and the most common shapes are herringbone and cross shapes. The flexible head of the steel support is an important supporting material widely used in construction projects, and its application principle is based on the strength and mobility of the material. By adjusting the length and angle, the support and movement control of the building structure are realized.

[0003] When the common flexible heads on the market are in use, first, they need to be bolted to the spliced steel pipes. During installation, they are directly placed on the supporting plate of the steel waling. The flexible end is supported by the supporting plate. Due to the heavy overall weight, when the soil in the foundation pit is loose, the supporting force of the steel waling supporting plate is not enough to support the weight of the whole steel pipe. Therefore, a new flexible structure of prestressed steel supports is proposed for the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a new flexible structure of prestressed steel supports to solve the problem of insufficient supporting force of the supporting plate when the soil in the foundation pit is loose.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A new flexible structure of prestressed steel supports includes a flexible head main body, a steel pipe for steel support, and a supporting plate for support. The flexible head main body includes a base, a first movable part, and a second movable part. One end of the base is fixedly connected to the first movable part, one end of the first movable part is slidably connected to the second movable part, one end of the second movable part is attached to the steel pipe, one side of the base is closely attached to the supporting plate, a limiting block is fixedly connected to the outside of the second movable part, one side of the limiting block is closely attached to a fixing ring, a screw is provided on one side of the fixing ring, first fixing blocks with a triangular cross-section are fixedly connected to both the upper and lower sides of the fixing ring, an electric cylinder is fixedly connected to the inclined surface of the first fixing block, one end of the electric cylinder is fixedly connected to a second fixing block with a triangular cross-section, a nail slides in the second fixing block, one end of the nail is fixedly connected to a moving plate, a steel rope is fixedly connected to the top of the base, the other end of the steel rope is fixedly connected to a fixing plate, and a bolt is provided on one side of the fixing plate.

[0007] Preferably, four limiting blocks are evenly distributed in the front, back, left, and right positions of the fixing ring, and the screws are arranged on the front and back sides of the fixing ring.

[0008] Preferably, two nails are arranged in a group on the same side of the moving plate, and the moving plate is inclined.

[0009] Preferably, two steel ropes are arranged in a group between the base and the fixing plate, and two bolts penetrate through the fixing plate in a group.

[0010] Preferably, the fixing ring is rotatably connected to the second movable member, and the second movable member is cylindrical.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, through the setting of the flexible head main body, the base, the first movable member, the second movable member, the steel pipe and the support plate, after the flexible head main body and the steel pipe are installed, one end of them is placed in the support plate, and the support plate plays a supporting role for one end of the flexible head main body. At this time, the support plate bears all the forces. Through the setting of the limit block, the fixing ring, the screw, the first fixing block, the electric cylinder, the second fixing block, the nail and the moving plate, the user controls the elongation distance of the electric cylinder to make the second fixing block closely fit with the inner wall of the foundation pit. By moving the moving plate to the left, the nail is nailed into the inner wall of the foundation pit to reduce the supporting force at the support plate. Through the setting of the steel rope, the fixing plate and the bolt, after the support plate supports the flexible head main body, the user holds the fixing plate and moves it upward to make the steel rope in a straight state, and then fixes the fixing plate at the foundation pit through the bolt, further reducing the supporting force at the support plate. Through the setting of the two structures, the supporting force at the support plate is reduced when the flexible head main body is supported, so that when the foundation pit is in a loose soil state, the flexible head main body is more stable after installation.
