Abstract
Description
Technical Field
[0001] The utility model specifically relates to a foundation pit inner support component, and belongs to the technical field of non-synchronous removal of complex inner supports of super-large foundation pits. Background Art
[0002] Crown beam, perimeter purlin, horizontal support, steel column and column piles are the basic components of the internal support system. The crown beam is a reinforced concrete continuous beam set on the top of the supporting structure around the foundation pit. One of its functions is to connect all the piles together. The perimeter purlin is an important load-bearing component that coordinates the force and deformation between the support and the retaining wall structure. The horizontal support is the main component that balances the horizontal force on the outside of the retaining wall. Steel support refers to the use of steel pipes, H-shaped steels, angle steels, etc. to enhance the stability of the engineering structure.
[0003] When the horizontal support column and the crown beam in the inner support member are connected, they are usually fixedly connected to the crown beam by bolts through the angle iron set at one end of the horizontal support column. However, after the fixed connection by bolts, if the staff finds that the horizontal support column is not in a horizontal state, it is inconvenient for the staff to adjust the angle of the horizontal support column. At the same time, when one end of the horizontal support column is fixedly connected to the crown beam by bolts, if the other end of the horizontal support column is still at a certain distance, it is inconvenient for the horizontal support column to be slightly adjusted in the horizontal direction.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The utility model aims to solve the deficiencies of the prior art and provide a support component in a foundation pit, so as to facilitate adjusting a horizontal support column to a horizontal level and facilitate slight movement of the horizontal support column.
[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a supporting structure in a foundation pit, comprising a horizontal supporting column and a crown beam which are vertically arranged, an adjusting box frame is symmetrically fixedly installed on the surface of one side of the crown beam, inner walls on both sides of the lower end of the adjusting box frame are provided with ridge hole plates with arc holes on the surface, a ridge rod plate is arranged inside the adjusting box frame, an adjusting frame is arranged between the ridge rod plate and the ridge hole plate, a spring telescopic rod is symmetrically arranged on the outer wall of one side of the adjusting frame, one end of the spring telescopic rod is slidably connected to the adjusting box frame, a reinforcing plate is fixedly installed on the lower surface of the adjusting frame, and the reinforcing plate and the horizontal supporting column are fixedly connected to each other.
[0007] Furthermore, in order to connect the adjustment box frame and the crown beam through the mounting screws, mounting plates are fixedly welded to the upper and lower surfaces of the adjustment box frame, and both ends of the mounting plates are threadedly connected to the crown beam through the mounting screws.
[0008] Furthermore, in order to fix the adjustment frame by means of the clamping limit between the ridge plate and the ridge hole plate, both ends of the adjustment frame are clamped to the lower end of the arc hole in the ridge hole plate, the lower end of the ridge plate is inserted in the ridge hole plate, and the lower end surface of the ridge plate fits with both ends of the adjustment frame.
[0009] Furthermore, in order to be able to clamp and limit one end of the spring telescopic rod, a sliding convex ball block is fixedly welded to one end of the spring telescopic rod, and a sliding convex ball groove is symmetrically opened on the inner wall of one side of the adjustment box frame, and the sliding convex ball block and the sliding convex ball groove are slidably clamped with each other.
[0010] Furthermore, in order to enable one end of the spring telescopic rod to be movably connected to the adjusting frame, thereby facilitating the staff to adjust the position of the adjusting frame inside the ridge hole plate, hinge plates are symmetrically arranged on both ends of the outer wall of one side of the adjusting frame, and one end of the spring telescopic rod is hingedly arranged between the hinge plates.
[0011] Furthermore, in order to be able to fix the spine plate by the fixing screw, and thereby enable the spine plate and the spinal hole plate to fix and limit the adjustment frame, a threaded hole is opened inside the spine plate, and a fixing screw is rotatably engaged in the threaded hole, and one end of the fixing screw passes through the inner wall of one end of the adjustment box frame and extends to the inside of the crown beam.
[0012] Furthermore, in order to limit the clamping plate by the guide rod so that the clamping plate can be lifted and lowered stably when it moves up and down, clamping plates are fitted on the upper surfaces of both ends of the spine plate, and guide rods are provided on the upper surfaces of both ends of the clamping plate, and the upper ends of the guide rods pass through the top wall of the adjustment box frame.
[0013] Furthermore, in order to facilitate the staff to adjust the position of the clamping plate, the spine plate is squeezed and limited by the clamping plate, and a pushing screw is rotatably installed on the upper surface of the clamping plate, and the upper end of the pushing screw passes through the inner top wall of the adjustment box frame.
[0014] The beneficial effect of the utility model is that when the horizontal support column has a certain elevation angle, the device can make slight angle adjustments to the horizontal support column through the movable connection between the adjustment frame and the spring telescopic rod, thereby avoiding the problem of the horizontal support column being difficult to adjust due to the fixed connection between the horizontal support column and the crown beam. At the same time, through the connection between the ridge plate, the ridge hole plate and the spring telescopic rod, the horizontal support column can be slightly adjusted in the horizontal direction, thereby ensuring the full connection between the horizontal support column and the crown beam. The device takes actual problem solving into consideration and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

The ball grooves are slidably connected to each other, and hinge plates 13 are symmetrically arranged at both ends of the outer wall of one side of the adjustment frame 7. One end of the spring telescopic rod 8 is hingedly arranged between the hinge plates 13. A threaded hole is opened inside the ridge plate 6, and a fixing screw 14 is rotatably engaged in the threaded hole. One end of the fixing screw 14 passes through the inner wall of one end of the adjustment box frame 3 and extends inside the crown beam 2, so that the staff can install the horizontal support column 1 on the upper end of the column pile vertically arranged in the foundation pit. At this time, the staff can install the adjustment box frame 3 of the horizontal support column 1 through the installation The screw rod 11 is installed to one side surface of the crown beam 2, and at this time the staff needs to determine whether the horizontal support column 1 is in a horizontal placement state. When the staff finds that one end of the horizontal support column 1 is not in the same horizontal line as the other end, the staff will slightly raise one end of the horizontal support column 1, and at this time one end of the spring telescopic rod 8 and the adjusting frame 7 begin to rotate.
