Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a foundation pit support device. Background Art

[0002] Steel sheet piles are commonly used construction equipment for foundation pit support. After the steel sheet piles are constructed, a purlin needs to be set on the inner wall and an inner support is fixed on the purlin. Since traditional inner supports are mostly integrated structures with fixed lengths, the two ends of the inner support cannot be smoothly connected and fixed to the purlin due to the accumulation of construction errors. To this end, the inventor proposed a foundation pit support device. Utility Model Content

[0029] Example 1

[0030] See also Figure 1-Figure 2 This embodiment provides a foundation pit supporting device to solve the problem that the two ends of the existing inner support cannot be smoothly connected and fixed with the surrounding purlin due to the accumulation of construction errors.

[0031] In this embodiment, the foundation pit supporting device includes a steel sheet pile 10, a purlin 20 and an inner support 30, wherein the inner support 30 includes a first support body 31 and a second support body 32 opposed to each other, an arc-shaped notch 311 and a baffle 312 are provided on the circumferential surface of the first support body 31, an arc-shaped plate 321 which is sleeved with the arc-shaped notch 311 is provided on the second support body 32, a sleeve 322 is screwed on the second support body 32, an end of the first support body 31 extends into the interior of the sleeve 322 and the baffle 312 abuts against the sleeve 322.

[0032] In this embodiment, the first support body 31 and the second support body 32 of the split design are connected by the sleeve 322 to form the inner support 30. When the sleeve 322 is screwed out from the second support body 32, it will push the baffle 312, so that the effective support length of the inner support 30 can be adjusted, which has the advantage of easy operation.

[0033] It is necessary to explain that the first support body 31 is constructed as a whole into a cylindrical shape, an arc-shaped notch 311 is formed on the outer wall of the first support body 31, and the arc-shaped notch 311 is arranged coaxially with the first support body 31 as a whole, the curvature of the arc-shaped notch 311 is less than 180 degrees, the arc-shaped notch 311 extends as a whole along the axial direction of the first support body 31 and extends to the outer end of the first support body 31, the baffle 312 is fixedly connected to the outer wall of the first support body 31 opposite to the arc-shaped notch 311, and the baffle 312 is constructed into an arc arranged coaxially with the first support body 31, the baffle 312 is away from the outer end of the first support body 31, that is, there is a certain distance between the baffle 312 and the outer end of the first support body 31, so that the outer end of the first support body 31 can extend into the sleeve 322.

[0034] In addition, the second support body 32 is also constructed as a cylindrical shape as a whole. As an example, the second support body 32 has the same outer diameter as the first support body 31. The arc plate 321 is formed at the outer end of the second support body 32, and the arc plate 321 is coaxially arranged with the second support body 32. The arc plate 321 extends along the axial direction of the second support body 32 as a whole. The curvature of the arc plate 321 is equal to the curvature of the arc notch 311. When the arc plate 321 is placed in the arc notch 311, the outer wall of the arc plate 321 and the outer wall of the first support body 31 are located on the same circumferential surface. The sleeve 322 is threadedly connected to the second support body 32. As the sleeve 322 is inserted into the outer end of the second support body 32, the arc plate 321 is rotated to the outer end of the second support body 32. When the sleeve 322 is in contact with the baffle plate 312, as the sleeve 322 continues to be rotated out, the sleeve 322 can push the first support body 31 through the baffle plate 312. At this time, the arc plate 321 slides on the arc notch 311, so that the first support body 31 and the second support body 32 move relatively away from each other, thereby achieving the purpose of increasing the effective support length of the inner support 30, so that the ends of the first support body 31 and the second support body 32 can be smoothly connected and fixed to the purlin 20, thereby ensuring the support effect of the inner support 30 on the steel sheet pile 10 through the purlin 20.

[0035] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
