Description

Technical Field

[0001] The utility model relates to the technical field of deep foundation pit foundation support construction, in particular to a deep foundation pit foundation support construction structure for a comprehensive teaching building. Background Art

[0002] During the construction of the comprehensive teaching building, in order to ensure the safety of nearby buildings, underground pipelines and nearby personnel, it is necessary to support the deep foundation pit of the teaching building. The deep foundation pit is a temporary structure set up during the construction of the teaching building. Usually, an underground space is excavated from the ground of the construction site as the foundation pit.

[0003] A support plate needs to be vertically arranged on the peripheral wall of the foundation pit. The support plate can be a steel plate or a cast slope protection. A support pipe is arranged inside the foundation pit. The support pipe is arranged between two support plates on the opposite side walls of the foundation pit. The support pipe can support the two support plates, thereby reducing the possibility of the support plates collapsing inwards due to the pressure of the surrounding soil. A Chinese patent (Announcement No.: CN 219157705 U) discloses a deep foundation pit support construction structure in a building construction project, which makes it more convenient for workers to assemble the support pipe. However, when adjusting the spacing between the transfer pipe and the connecting pipe in the above document, the anchor bolt needs to be removed from the reinforcement seat before the transfer pipe can be removed from the support plate so that the transfer pipe can be rotated outside the screw rod. When the transfer pipe is rotated, the reinforcement seat will be driven to rotate, and it is difficult to ensure that the mounting hole of the reinforcement seat corresponds to the mounting hole on the support plate. After the transfer pipe and the connecting pipe are adjusted, the transfer pipe is inconvenient to be fixed on the support plate. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 In this embodiment, a comprehensive teaching building deep foundation pit foundation support construction structure includes two support plate main bodies 1, a plurality of transfer tubes 2 are fixed on the opposite sides of the two support plate main bodies 1, a connecting pipe 3 is provided on the opposite sides of the left and right transfer tubes 2, a fixing flange 4 is fixed on the opposite ends of the left and right connecting tubes 3, an adjusting rod 5 is fixed on the opposite ends of the two transfer tubes 2, a connecting block 6 is fixed on the opposite ends of the two adjusting rods 5, a connecting groove 7 is opened on the top of the transfer tube 2, and a limit assembly is provided inside the connecting block 6.

[0022] See also Figure 2-3 The limiting assembly in this embodiment includes two abutting blocks 71 abutting the front and rear walls of the inner cavity of the connecting groove 7, semicircular blocks 72 are fixed at opposite ends of the two abutting blocks 71, supporting plates 73 are slidably connected to the outer surfaces of the abutting blocks 71, and vertical blocks 74 are fixed at the upper and lower ends of the abutting blocks 71. The limiting assembly also includes an operating assembly arranged at opposite ends of the two abutting blocks 71.

[0023] Among them, the adjusting rod 5 is located inside the connecting groove 7 and is slidably connected thereto, so that the adjusting rod 5 can pass through the connecting groove 7 inside the transfer tube 2. Friction pads are fixed on the opposite ends of the two abutment blocks 71, which can enhance the friction force between the abutment blocks 71 and the front and rear walls of the inner cavity of the connecting groove 7.

[0024] In addition, through holes are provided at both the front and rear ends of the connecting block 6, and the abutment block 71 passes through the through holes to the interior of the connecting block 6 and is slidably connected thereto, so that the abutment block 71 can move into or out of the interior of the connecting block 6 through the through holes.

[0025] In addition, through holes are provided on opposite sides of the two support plates 73, and the abutment block 71 penetrates into the through holes and is slidably connected thereto, so that the abutment block 71 can move inside the support plates 73, so that the support plates 73 can support the abutment block 71, so that the abutment block 71 can stably slide inside the connecting block 6.

[0026] Two slide grooves are provided on the left and right walls of the inner cavity of the connecting block 6. The left and right ends of the vertical block 74 are located inside the slide grooves and are slidably connected thereto. The vertical block 74 is T-shaped, which can limit the movement range of the abutting block 71 and the connecting block 6.

[0027] See also Figure 3 The operating assembly in this embodiment includes a spring 75 sleeved on the outer surface of the abutment block 71, and the operating assembly also includes a push block 76 abutting against the opposite end of the two abutment blocks 71. The top end of the push block 76 is rotatably connected with a bolt 77 through a bearing, and sliding grooves 78 are provided at both the front and rear ends of the push block 76.

[0028] Among them, a threaded hole is opened at the top of the connecting block 6, and a bolt 77 passes through the inner side of the threaded hole and is threadedly connected with it, so that the bolt 77 can move in or out of the interior of the connecting block 6, which can drive the push block 76 to move in the connecting block 6.

[0029] Moreover, the semicircular block 72 is located inside the sliding groove 78 and is slidably connected thereto. The sliding groove 78 is arc-shaped. The push block 76 can push the two semicircular blocks 72 to move relative to or away from each other through the two sliding grooves 78 .

[0030] The working principle of the above embodiment is:

[0031] When in use, when it is necessary to adjust the distance between the transfer tube 2 and the connecting tube 3, the bolt 77 is turned so that the bolt 77 drives the push block 76 to move upward in the inner cavity of the connecting block 6, so that the two semicircular blocks 72 are no longer in contact with the top of the push block 76, and the spring 75 can push the two sets of vertical blocks 74 to move relative to each other, so that the two sets of vertical blocks 74 can drive the two abutting blocks 71 to move relative to each other. While the abutting blocks 71 move, the semicircular blocks 72 can gradually move into the two sliding grooves 78, so that the two abutting blocks 71 no longer abut against the front and rear walls of the inner cavity of the connecting groove 7, so that the adjusting rod 5 can move in the transfer tube 2. When it moves to a suitable distance, the bolt 77 is turned so that the bolt 7 7 drives the push block 76 to move downward, and the push block 76 moves to the top of the push block 76 through the two sliding grooves 78, thereby pushing the two semicircular blocks 72 to move back to each other, so that the two vertical blocks 74 of the same group cooperate with the support plate 73 to squeeze the spring 75, so that the two abutment blocks 71 can move back to each other and can be abutted and fixed on the front and rear walls of the inner cavity of the connecting groove 7, so that the adjustment rod 5 can be fixed in the connecting groove 7 of the transfer tube 2, so as to complete the spacing between the transfer tube 2 and the connecting tube 3, and there is no need to remove the reinforcement seat from the support plate, avoiding the phenomenon that the mounting hole of the reinforcement seat does not correspond to the mounting hole on the support plate, which can effectively improve the convenience during adjustment.
