DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] As Figure 1 , Figure 2 shown, a modular steel collar component convenient for quick installation includes an I-beam collar 1, a support base 2, a support column 3, and a connecting section 4.

[0019] As Figure 1 , Figure 2 shown, the I-beam collar 1 is horizontally arranged on both sides of the foundation pit, and the support base 2 is used to connect the I-beam collar 1 on each side. The support column 3 is horizontally arranged on the support base 2, and the connecting section 4 is horizontally arranged between a pair of support columns 3.

[0020] As Figure 1 , Figure 2 shown, the support base 2 includes a seat pipe 21, a seat body 22, and a hydraulic cylinder 23. The seat pipe 21 is connected to the support column 3, the seat body 22 is slidably connected to the seat pipe 21, and a hook 24 for hooking the I-beam collar 1 is arranged on the seat body 22. The hydraulic cylinder 23 is arranged in the seat pipe 21 and is used to control the horizontal sliding of the seat body 22.

[0021] AsFigure 2 , Figure 3 As shown in Figure 3 , the connecting section 4 includes a fixed pipe 41 and a pair of sliding pipes 42. The sliding pipes 42 are horizontally slidably connected to both ends of the fixed pipe 41. A bidirectional lead screw 43 is horizontally rotatably connected to the middle position of the fixed pipe 41. Both ends of the bidirectional lead screw 43 are threadedly connected with sliders 44. A pull rod 45 is rotatably connected to both sides of each slider 44, and the other end of the pull rod 45 is rotatably connected to the sliding pipe 42.

[0022] As Figure 2 , Figure 3 As shown in Figure 3 , dovetail blocks 31 are provided at both ends of the support column 3. Grooves 32 for the dovetail blocks 31 to be embedded in and dovetail grooves 33 connecting the grooves 32 and for the dovetail blocks 31 to be slidably embedded in are provided at the end positions of the seat body 22 and the sliding pipe 42. Bolts 34 passing through the seat body 22 or the sliding pipe 42 are provided at both ends of the support column 3.

[0023] When the foundation pit needs to be supported, first horizontally fix the I-beam purlin 1 on both sides of the foundation pit, then place the support column 3 between the support base 2 and the connecting section 4, and make the dovetail blocks 31 on the support column 3 be embedded in the grooves 32 at the ends of the seat body 22 and the sliding pipe 42. Then control the rotation of the support column 3 to make the dovetail blocks 31 be embedded in the dovetail grooves 33, and use the bolts 34 to fix the support column 3, the seat body 22 and the sliding pipe 42, completing the connection of the support base 2, the support column 3 and the connecting section 4, and completing the assembly connection of the entire steel support structure.

[0024] Then control the rotation of the bidirectional lead screw 43 to make the bidirectional lead screw 43 drive the sliders 44 to slide relative to each other, and control the flipping of the pull rods 45. Use the pull rods 45 to control the relative sliding of the sliding pipes 42, so as to realize the length adjustment of the entire steel support structure for adapting to foundation pits with different spans.

[0025] Subsequently, lift the support base 2, the support column 3 and the connecting section 4, and make the hooks 24 at both ends of the seat body 22 hook tightly on the I-beam purlin 1. Then start the hydraulic cylinder 23 to make the seat body 22 slide outwards and press tightly against the I-beam purlin 1, realizing the tight fixing of the I-beam purlin 1 and completing the support of the foundation pit.

[0026] Therefore, by setting the telescopic steel support structure, the free adjustment of the length of the steel support structure is realized, so as to tightly fix the I-beam purlins 1 on both sides of the foundation pit, making the construction process of the entire steel purlin assembly easier and more convenient. At the same time, by setting the modular and easily assembled steel support structure, the rapid assembly and construction at the construction site are realized, improving the construction efficiency.

[0027] As Figure 2 , Figure 4As shown, a vertical column 5 is vertically arranged at the middle position of the support column 3. The vertical column 5 includes a base 51, a vertical rod 52, and a fixing head 53. The base 51 is horizontally fixed to the bottom wall of the foundation pit. Multiple sections of the vertical rod 52 are connected to each other and fixed to the base 51. The fixing head 53 is arranged on the uppermost vertical rod 52 and is connected to the support column 3.

[0028] As Figure 2 、 Figure 4 shown, a pair of clamping blocks 54 are arranged on the lower end surface of the vertical rod 52. Accommodating grooves 55 for the clamping blocks 54 to be embedded are arranged on the upper end surfaces of the base 51 and the vertical rod 52, and clamping grooves 56 connected to the accommodating grooves 55 and into which the clamping blocks 54 can be rotated and embedded are arranged.

[0029] As Figure 2 、 Figure 4 、 Figure 5 shown, a locking rod 57 with a rectangular cross-section is vertically and slidably connected inside the vertical rod 52, and a spring 58 for controlling the upward sliding of the locking rod 57 is arranged inside the vertical rod 52. A locking hole 59 for the locking rod 57 to be inserted is arranged on the base 51, and an insertion rod 531 inserted into the uppermost vertical column 5 is arranged on the lower end surface of the fixing head 53.

[0030] As Figure 4 、 Figure 5 shown, a handle 6 is rotatably connected to the outer wall of the upper end of the uppermost vertical rod 52, and a locking hook 61 for hooking the fixing head 53 is arranged at the middle position of the handle 6.

[0031] As Figure 4 shown, the fixing head 53 includes a head end 532, a bracket 533, and a jack 534. The head end 532 is arranged on the uppermost vertical rod 52. The bracket 533 is vertically slidably connected to the head end 532. A hoop 535 for clamping the support column 3 is arranged on the bracket 533, and the jack 534 is used to control the vertical sliding of the bracket 533.

[0032] After the I-beam purlin 1 is supported, the vertical column 5 is taken out. First, the base 51 is fixed to the bottom of the foundation pit, and then the vertical rod 52 is taken out. The clamping block 54 at the lower end of the vertical rod 52 is embedded into the accommodating groove 55 on the base 51, and then the vertical rod 52 is controlled to rotate so that the clamping block 54 rotates into the clamping groove 56 to realize the connection between the vertical rod 52 and the base 51. Then, according to the same principle, each section of the vertical rod 52 is connected.

[0033] Meanwhile, the locking rod 57 in the lowermost vertical rod 52 is rotated to align with the locking hole 59 on the base 51, and at the same time, the locking rods 57 in the adjacent vertical rods 52 are aligned with each other. Then the fixing head 53 is taken out, placed on the uppermost vertical rod 52, and the insertion rod 531 at the lower end of the fixing head 53 is inserted into the uppermost vertical rod 52.

[0034] Then, control the handle 6 to flip upward, and control the locking hook 61 to hook the end 532 on the fixed head 53. Then, control the handle 6 to flip downward. Under the action of the lever principle, the fixed head 53 moves downward, and the insertion rod 531 is completely inserted into the vertical rod 52. At the same time, all the locking rods 57 in the vertical rod 52 slide downward completely. Finally, the lowermost locking rod 57 is inserted into the locking hole 59. Finally, fix the end 532 on the vertical rod 52 to complete the assembly and fixation of the entire column 5.

[0035] Subsequently, use the jack 534 to control the bracket 533 to move upward, and use the hoop 535 to tightly hold the support column 3 to achieve the support and fixation of the support column 3, thereby realizing the support of the entire steel support structure and increasing the stability during the use of the entire steel waling assembly.
