Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, and in particular to a node for arranging guide bars for lowering the load box of an auxiliary anti-uplift pile guide tube. Background Technology
[0002] The main working mechanism of tension piles is to resist axial tensile force through the friction between the pile and the soil. Piles that withstand vertical uplift are called tension piles. Tension piles are widely used in anti-buoyancy systems for large basements, anti-uplift systems for tall buildings and structures, and anchor pile foundations in static load test piles. In areas with high groundwater levels, when the load of the superstructure cannot balance the buoyancy of the groundwater, the structure as a whole or in parts will be subjected to upward buoyancy. Tension piles must be installed in basement structures of buildings.
[0003] In existing methods for constructing tension piles, a pull-out test is required during construction to check whether the tension performance of the tension pile meets the requirements. A load cell is set at the bottom of the pile foundation. However, during the concrete pouring process, the concrete duct is prone to jamming at the opening of the load cell. At the same time, the tension pile load cell is located underwater, and the actual situation of the duct and the opening of the load cell cannot be observed from above. Therefore, it is difficult to adjust the duct from the ground. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a node for arranging guide bars for lowering the load box of the anti-tension pile guide pipe, so as to solve the problems of the guide pipe getting stuck at the diameter of the load box during the concrete pouring process and the difficulty in adjusting the position of the guide pipe after passing through the diameter of the load box.
[0005] To achieve the above technical effects, this utility model provides a node for arranging guide bars for lowering the load box of an auxiliary anti-tension pile guide pipe, which includes:
[0006] The tensile pile has a load cell at the bottom of the pile foundation. Multiple guide bars are evenly arranged radially on the inner side of the diameter of the load cell. The multiple guide bars are arranged one-to-one with the main bars of the tensile pile reinforcement cage. The first end of the multiple guide bars is fixed to the inner side of the diameter of the load cell and bends and extends towards the center of the diameter to form a first bend end. The second end is fixedly connected to the corresponding main bar. The first bend ends of the multiple guide bars form a guide hole for the tensile pile guide pipe to be lowered and pass through.
[0007] Preferably, the angle between the surface of the load box and the axial direction of the guide rib is 60°.
[0008] Preferably, the first bent end is arranged parallel to the surface of the load box.
[0009] Preferably, the second end of the guide rib bends and extends in a direction away from the load box to form a second bent end, the second bent end being arranged parallel to the main rib and used for fixed connection with the main rib.
[0010] Preferably, an L-shaped reinforcing rib is fixedly connected between the surface of the load cell and each of the main reinforcing bars.
[0011] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:
[0012] 1) The concrete guide pipe can be laid straight through the opening of the load box along the guide bar to avoid subsequent adjustments.
[0013] 2) The guide bars are connected to the main bars of the steel cage and the load box to reinforce the load box.
[0014] 3) To achieve control over the thickness of the protective layer of tie bars for masonry infill walls of different thicknesses;
[0015] 4) Avoid jamming between the conduit connection and the load box during the removal of the conduit. Attached Figure Description
