Detailed implementation manners

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

[0018] As Figure 1 , Figure 2 shown, an angle-adjustable steel support structure includes a steel waling 1, a steel support 2 and an adjusting seat 3. The steel waling 1 is horizontally arranged on the sheet piles inside the foundation pit, and the steel support 2 is arranged between the two steel walings 1 on both sides.

[0019] As Figure 2 , Figure 3 shown, the adjusting seat 3 is arranged at both ends of the steel support 2. The adjusting seat 3 includes a fixed seat 31 and a movable seat 32 arranged in a plate shape. The fixed seat 31 is connected to the steel waling 1, and the movable seat 32 is rotatably connected to the fixed seat 31 through a hinge shaft.

[0020] As Figure 2 , Figure 3 shown, multiple layers of arc-shaped adjusting pipes 33 are arranged on the movable seat 32, and an adjusting rod 34 slidably connected to the adjusting pipes 33 is arranged on the fixed seat 31. A U-shaped locking rod 331 is vertically inserted into the adjusting pipe 33, and a locking hole 341 for the locking rod 331 to penetrate is arranged on the adjusting rod 34.

[0021] As Figure 2 , Figure 3 shown, a rotating shaft 332 is vertically arranged between the multiple layers of adjusting pipes 33, and a gear 333 located inside the adjusting pipe 33 is arranged on the rotating shaft 332. A long strip-shaped adjusting hole 342 is arranged on the adjusting rod 34, and a rack 343 meshing with the gear 333 is arranged on one side of the adjusting hole 342.

[0022] When the foundation pit needs to be supported, first horizontally fix the steel waling 1 on the steel sheet piles, then take out the adjusting seat 3, and install the fixing seat 31 on the adjusting seat 3 on the steel waling 1. Subsequently, control the rotation of the rotating shaft 332, and the rotating shaft 332 drives the gear 333 to rotate. At this time, under the cooperation of the gear 333 and the rack 343, control all the adjusting rods 34 to slide synchronously, and realize the adjustment of the included angle between the fixing seat 31 and the movable seat 32.

[0023] When the included angle between the fixing seat 31 and the movable seat 32 meets the installation requirements, penetrate the locking rod 331 through the locking hole 341 to fix the adjusting pipe 33 and the adjusting rod 34, so as to realize the fixation of the fixing seat 31 and the movable seat 32. Finally, the steel support 2 can be fixed on the adjacent movable seat 32 to complete the support of the foundation pit.

[0024] Therefore, by setting the adjusting seats 3 with adjustable angles at both ends of the steel support 2, the included angle between the two side steel walings 1 can be compensated, so that the steel support 2 can be stably connected to the steel waling 1 through the adjusting seat 3 without welding corbels or installing pads, ensuring the rapid construction of the steel support 2 and improving the construction efficiency.

[0025] As Figure 3 shown, on the sides of the fixing seat 31 and the movable seat 32 close to each other, there are inclined struts 4 rotatably connected. The end of the inclined strut 4 is rotatably connected with a fixing block 41. A screw 42 is arranged on the fixing block 41, and a row of screw holes 43 for the screw 42 to be screwed into are arranged on both the fixing seat 31 and the movable seat 32.

[0026] After the included angle between the fixing seat 31 and the movable seat 32 is adjusted, the inclined strut 4 and the fixing block 41 can be controlled to rotate, and the fixing block 41 is made to fit the corresponding fixing seat 31 or movable seat 32, and then the screw 42 is screwed into the corresponding screw hole 43 to complete the fixation of the inclined strut 4, increasing the stability and compressive capacity between the fixing seat 31 and the movable seat 32, and ensuring the stable support of the foundation pit.

[0027] As Figure 4 shown, a through hole 5 is arranged on the side wall of the adjusting pipe 33. A clamping plate 51 is embedded in the through hole 5, and clamping teeth 52 are arranged on the inner side of the clamping plate 51. A clamping groove 53 for the clamping teeth 52 to be embedded is arranged on the outer wall of the adjusting rod 34, and a driving mechanism 6 for controlling the sliding of the clamping plate 51 is arranged on the adjusting pipe 33.

[0028] As Figure 4 shown, the driving mechanism 6 includes a gantry 61, a screw 62 and a handle 63. The gantry 61 is arranged on the adjusting pipe 33. The screw 62 is threadedly connected to the gantry 61 and rotatably connected to the clamping plate 51, and the handle 63 is arranged at the end of the screw 62.

[0029] After the adjusting rod 34 and the adjusting tube 33 have completed relative sliding, the control handle 63 drives the screw rod 62 to rotate. The screw rod 62 drives the clamping plate 51 to slide inward, and the clamping teeth 52 on the clamping plate 51 are inserted into the clamping groove 53 on the adjusting rod 34, realizing the secondary fixation between the adjusting rod 34 and the adjusting tube 33, increasing the stability between the two, and realizing the stable support and fixation between the fixed seat 31 and the movable seat 32.

[0030] As Figure 5 shown, a pair of clamps 7 for clamping the steel collar 1 are arranged on the back side of the fixed seat 31. A bidirectional lead screw 71 is vertically rotatably connected in the fixed seat 31, and the bidirectional lead screw 71 is threadedly connected to the pair of clamps 7.

[0031] As Figure 5 shown, a plurality of positioning plates 11 are transversely and spacedly arranged on the steel collar 1, and positioning grooves 72 for the positioning plates 11 to be inserted into are arranged on the clamps 7.

[0032] When it is necessary to install the adjusting seat 3 on the steel collar 1, control the fixed seat 31 to fit the steel collar 1, then control the bidirectional lead screw 71 to rotate, and make the pair of clamps 7 approach each other to realize the clamping of the steel collar 1. At the same time, the positioning plates 11 on the steel collar 1 are inserted into the positioning grooves 72 on the clamps 7, realizing the limit fixation in the transverse direction and realizing the quick connection and fixation between the adjusting seat 3 and the steel collar 1.

[0033] As Figure 2 shown, connecting plates 21 are arranged at both ends of the steel support 2. A slide rail 8 with an upper end opening and for the connecting plates 21 to vertically slide and be inserted into is arranged on the movable seat 32, and a tie bolt 81 for pressing the connecting plates 21 is transversely penetrated through the slide rail 8.

[0034] When it is necessary to install the steel support 2, lift the steel support 2, and make the connecting plates 21 at the end of the steel support 2 be located above the slide rail 8. Then make the connecting plates 21 slide into the slide rail 8, and finally install the tie bolt 81 to complete the quick installation and fixation of the steel support 2.

[0035] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
