Description

Technical Field

[0001] This utility model relates to the field of foundation pit support, and in particular to a modular steel support component. Background Technology

[0002] Steel supports are commonly used support components in deep foundation pit support engineering. They are usually used in conjunction with steel walers to enhance the stability of the foundation pit sidewalls and prevent soil landslides or collapses. Steel support components in related technologies typically include a support section and two support seats. The two support seats are fixed to the corresponding ends of the support section and are used to connect and cooperate with the support brackets on the steel walers.

[0003] However, when the foundation pit is wide, the overall length and weight of the steel support components increase accordingly, posing a risk of deformation and potential support failure. Furthermore, relying solely on support brackets on the two steel walers to support the entire steel support component carries the risk of bracket breakage, leading to the steel support component falling. This poses a significant safety risk and requires improvement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular steel support component that can improve the support effect of the steel support component in the vertical direction, reduce the risk of deformation of the steel support component, so as to ensure the support effect. At the same time, it can also share the load of the support bracket on the steel waler to reduce the risk of the steel support component falling off, thereby improving the safety of use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a modular steel support component, including a support part, with support seats respectively provided at both ends of the support part, and multiple support rings fixedly connected to the support part. The multiple support rings are arranged at equal intervals along the length direction of the support part. A load-bearing column is vertically arranged below the support part. A limit seat is provided at the top of the load-bearing column and an installation seat is provided at the bottom. The limit seat can be connected to any of the support rings, and the installation seat is used to fix it to the soil layer at the bottom of the foundation pit.

[0006] Optionally, the limiting seat includes a limiting strip fixed to the top of the load-bearing column, and the limiting strip is provided with a limiting groove for either of the support rings to be tightly engaged.

[0007] Optionally, a plurality of reinforcing ribs are provided between the load-bearing column and the limiting strip, and each of the reinforcing ribs is fixedly connected to the load-bearing column and the limiting strip respectively.

[0008] Optionally: The load-bearing column includes an upper column, a middle column, and a lower column that are coaxially connected from top to bottom. The top of the upper column is fixedly connected to the limiting seat, the bottom of the lower column is fixedly connected to the mounting seat, and the top of the middle column is detachably connected to the upper column and the bottom is detachably connected to the lower column.

[0009] Optionally: The top and bottom of the middle support column are respectively vertically fixedly connected with rectangular positioning columns, and the bottom of the upper support column and the top of the lower support column are respectively provided with positioning grooves for the corresponding positioning columns to be tightly inserted; The bottom of the upper support column and the top of the lower support column are respectively provided with multiple locking bolts, and multiple mounting holes are respectively provided through the two positioning columns, and the mounting holes are for the screws of the corresponding locking bolts to pass through.

[0010] Optionally, the support includes a plurality of support cylinders arranged in sequence, with two adjacent support cylinders being detachably connected by a set of limiting flanges, and the plurality of support rings being fixed at the middle position of the corresponding support cylinder.

[0011] Optionally, the two support seats are detachably connected to the corresponding support cylinders via a set of locking flanges.

[0016] Reference Figure 1 , Figure 2 A modular steel support component includes a horizontally arranged support section 1, with support seats 2 at both ends of the support section 1. The support seats 2 are used to connect with support brackets on a steel waler. Multiple support rings 3 are fixedly connected to the support section 1, and the multiple support rings 3 are arranged at equal intervals along the length of the support section 1. A load-bearing column 4 is vertically arranged below the support section 1. The top of the load-bearing column 4 is equipped with a limiting seat 5, and the bottom is equipped with a mounting seat 6. The limiting seat 5 can be connected to any of the support rings 3, and the mounting seat 6 can be fixed to the bottom of the pit by multiple nails.

[0017] The support column 4 provides vertical support to the support part 1, which improves the vertical support effect of the steel support and reduces the risk of deformation of the steel support, thus ensuring the support effect. At the same time, it can also share the load of the support bracket on the steel waler, thereby reducing the risk of the steel support falling and improving the safety of use.

A plurality of reinforcing ribs 53 are provided between the load-bearing column 4 and the limiting strip 51, and each reinforcing rib 53 is fixedly connected to the load-bearing column 4 and the limiting strip 51 respectively, so as to improve the structural strength of the limiting seat 5.

[0019] Reference Figure 2 , Figure 3 The load-bearing column 4 includes an upper column 41, a middle column 42 and a lower column 43 connected coaxially from top to bottom. The top of the upper column 41 is fixedly connected to the limiting seat 5, and the bottom of the lower column 43 is fixedly connected to the mounting seat 6. The top of the middle column 42 is detachably connected to the upper column 41 and the bottom is detachably connected to the lower column 43.

[0020] By setting up modular load-bearing columns 4, it is convenient for workers to transport and operate the load-bearing columns 4, and at the same time, it is possible to produce the load-bearing columns 4 in a modular manner, thereby reducing production costs. In addition, by replacing the middle support columns 42 with different lengths, the height of the load-bearing columns 4 can be adjusted to adapt to foundation pits of different depths.

[0021] Reference Figure 2 , Figure 3The top and bottom of the middle support column 42 are vertically fixed with rectangular positioning posts 44, and the bottom of the upper support column 41 and the top of the lower support column 43 are respectively provided with positioning grooves 45 for the corresponding positioning posts 44 to be tightly inserted.

Meanwhile, two support seats 2 are detachably connected to the corresponding support cylinders 11 by a set of locking flanges 7.

[0023] By setting up a modular support unit 1, it is convenient for workers to transport and operate the support unit 1, while also enabling modular production of the support unit 1, reducing production costs. Furthermore, the number of support cylinders 11 can be increased or decreased to adjust the length of the support unit 1, thereby adapting to foundation pits of different sizes.

[0024] Furthermore, each support cylinder 11 is equipped with a support ring 3 so that the load-bearing column 4 can support any position of the support part 1. Of course, the number of components such as the load-bearing column 4 can also be increased to achieve synchronous support of multiple positions of the support part 1, thereby improving the support effect of the support part 1.
