Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a steel support structure. Background Technology

[0002] Steel supports for foundation pits are an important temporary support structure used in the excavation of deep foundation pits. Their main function is to prevent soil slippage or collapse on the sidewalls of the pit, ensuring construction safety. In urban construction and underground space development, with the increasing demand for underground space utilization, the scale and depth of foundation pit projects are constantly increasing, leading to the increasingly widespread application of steel supports for foundation pits.

[0003] Traditional steel supports are usually fixed between the steel walers on both sides during construction and installation. When the span of the steel support is large, it is necessary to erect columns on the ground to provide support in the middle of the steel support in order to ensure its stability.

[0004] However, traditional column construction requires on-site measurement to determine the required height before cutting the material, followed by welding and assembly. This method makes the column erection process inconvenient, affects the construction schedule, and needs improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel support structure that can improve the construction progress.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel support structure, comprising:

[0007] A support column, cylindrical in shape, is positioned between two steel walers on either side. The support column includes a fixed head, a movable head, and a connecting rod. The connecting rod is fixed between the fixed head and the movable head via a flange.

[0008] The column is vertically installed on the bottom wall of the foundation pit and is used to support the connecting rod;

[0009] The column includes a base, a pair of channel steels, an I-beam, and a bracket. The base is horizontally installed on the bottom wall of the pit. The pair of channel steels are vertically and side by side on the base. The I-beam is vertically and slidably connected to the pair of channel steels. Multiple tie bolts are horizontally and spaced apart between the pair of channel steels. The I-beam is provided with mounting holes for the tie bolts to pass through. The bracket is located at the upper end of the I-beam and is used to support the connecting rod.

[0010] In a preferred embodiment, the present invention can be further configured such that: the bracket includes a base plate, a top plate, and a driving mechanism; the base plate is horizontally disposed on the upper end of the I-beam; the top plate is disposed above the base plate; and the driving mechanism is used to control the vertical sliding of the top plate.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the driving mechanism includes a pair of driving blocks, a bidirectional lead screw, and a pair of driving rods. The pair of driving blocks are horizontally slidably connected to the base plate. The bidirectional lead screw is horizontally rotatably connected to the base plate and threadedly connected to the pair of driving blocks. The pair of driving rods are arranged in a figure-eight shape, with their lower ends rotatably connected to the driving blocks and their upper ends rotatably connected to the top plate.

[0012] In a preferred embodiment, the present invention can be further configured such that a pair of clamping rods are provided on the top plate to hold the two sides of the connecting rod.

[0013] In a preferred embodiment, the present invention can be further configured such that: the clamping rod is horizontally slidably connected to the top plate, the top plate is horizontally rotatably connected to a bidirectional screw, and the lower end of the clamping rod is threadedly connected to the bidirectional screw.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, a steel support structure includes a support column 1 and a column 2.

[0025] like Figure 1 As shown, the support column 1 is cylindrical and is set between the steel walers on both sides. The support column 1 includes a fixed head 11, a movable head 12 and a connecting rod 13. The connecting rod 13 is fixed between the fixed head 11 and the movable head 12 through a flange.

[0026] like Figure 1 , Figure 2 As shown, the column 2 is vertically installed on the bottom wall of the pit and is used to support the connecting rod 13. The column 2 includes a base 21, a pair of channel steels 22, an I-beam 23 and a bracket 24.

[0027] like Figure 1 , Figure 2 As shown, the base 21 is horizontally set on the bottom wall of the pit, a pair of channel steels 22 are vertically and side by side set on the base 21, and an I-beam 23 is vertically and slidably connected to the pair of channel steels 22. Multiple tie bolts 25 are horizontally and spaced apart between the pair of channel steels 22, and the I-beam 23 is provided with mounting holes 26 for the tie bolts 25 to pass through.

[0028] like Figure 1 , Figure 2 As shown, bracket 24 is disposed at the upper end of I-beam 23 and is used to support connecting rod 13. Bracket 24 includes base plate 241, top plate 242 and drive mechanism 243. Base plate 241 is horizontally disposed at the upper end of I-beam 23, and top plate 242 is disposed above base plate 241.

[0029] like Figure 1 , Figure 2 As shown, the drive mechanism 243 is used to control the vertical sliding of the top plate 242. The drive mechanism 243 includes a pair of drive blocks 244, a bidirectional lead screw 245, and a pair of drive rods 246.

[0030] like Figure 1 , Figure 2 As shown, a pair of drive blocks 244 are horizontally slidably connected to the base plate 241, and a bidirectional lead screw 245 is horizontally rotatably connected to the base plate 241 and threadedly connected to the pair of drive blocks 244. A pair of drive rods 246 are arranged in a figure-eight shape, with their lower ends rotatably connected to the drive blocks 244 and their upper ends rotatably connected to the top plate 242.

[0031] When it is necessary to build a steel support structure, the support column 1 is first assembled on the ground, fixing the fixed head 11, the movable head 12 and the connecting rod 13 together. Then the entire support column 1 is hoisted to connect the support column 1 with the steel waler to achieve the support of the steel waler.

[0032] Then, the column 2 is placed vertically below the connecting rod 13, and the base 21 is fixed to the bottom wall of the pit. Then, the I-beam 23 is controlled to drive the bracket 24 to slide up and down until the bracket 24 is about to touch the support rod. Then, all the tie bolts 25 are passed through the channel steel 22 and the I-beam 23 to fix the channel steel 22 and the I-beam 23.

[0033] Then, control the rotation of the bidirectional lead screw 245, and use the bidirectional lead screw 245 to drive a pair of drive blocks 244 to move closer to each other, and cause the drive blocks 244 to drive the drive rod 246 to flip, and use the drive rod 246 to push the top plate 242 to move upward, so that the top plate 242 abuts against the support rod, thereby achieving the support of the entire support column 1.

[0034] Therefore, by setting up modular columns 2, they can be assembled and erected on site. At the same time, the use of telescopic columns 2 allows for free adjustment of the height of columns 2, adapting to different height requirements, improving construction efficiency and progress. Furthermore, columns 2 can be disassembled and transported, facilitating reuse and recycling.

[0035] Meanwhile, by setting up a height-adjustable bracket 24, the height of the entire column 2 can be infinitely adjusted, ensuring stable support for the support column 1 and improving practicality.

[0036] like Figure 1 , Figure 2 As shown, a pair of clamping rods 3 are provided on the top plate 242 to clamp the two sides of the connecting rod 13. The clamping rods 3 are horizontally slidably connected to the top plate 242. A bidirectional screw 31 is horizontally rotatably connected to the top plate 242. The lower end of the clamping rod 3 is threadedly connected to the bidirectional screw 31.

[0037] like Figure 1 , Figure 2 As shown, a pressure rod 32 is horizontally arranged at the upper end of the clamping rod 3 to press the upper end of the connecting rod 13, and the upper end of the clamping rod 3 extends vertically upward. A diagonal brace 33 is arranged between the pressure rod 32 and the clamping rod 3.

[0038] When the top plate 242 abuts against the support rod, a pair of clamping rods 3 are located on both sides of the support rod. Then, the bidirectional screw 31 is controlled to rotate, so that the bidirectional screw 31 controls the pair of clamping rods 3 to move closer to each other and clamp both sides of the support rod to increase the stability of the connection position.

[0039] At the same time, the clamping rod 3 drives the pressure rod 32 to move synchronously and presses the upper end face of the support rod. Under the action of the diagonal brace 33, the structural strength of the pressure rod 32 is increased, the support rod is fixed, the stability between the entire bracket 24 and the support column 1 is increased, and the support column 1 is stably supported.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
