Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction devices, in particular to a novel pile foundation sleeve. Background Art
[0002] In existing building construction, whether it is bridges, station buildings or civil construction foundations, steel cage piles need to be made. When the depth exceeds a certain size, the piles need to be connected. The connection method is difficult and requires different methods such as welding, extrusion connection and threaded connection. For example, welding is not suitable because grade 3 and grade 4 steel bars are widely used, have high rigidity, many impurities and are easy to crack. Extrusion connection has low construction efficiency and is inconvenient to operate, so it is also not suitable. The sampling threaded connection processes the threaded length of the steel bar end to the sleeve length, and it is very difficult to process it to meet the requirements. The sleeve needs to be fully screwed in and then returned to the other steel bar end and locked with a nut. The quality of this type of connection thread head cannot be guaranteed, and it is difficult to meet the tensile strength requirements. Therefore, the existing connection technology cannot meet the industry standard requirements, which in turn results in low construction efficiency, high labor intensity, and unguaranteed construction quality. Therefore, improvements are needed to address the above problems. Utility Model Content
[0003] In response to the above situation, in order to overcome the current technical defects, the utility model provides a new type of pile foundation sleeve, through which all-round connection can be achieved on the basis of meeting the mechanical connection performance of steel bars. It has the advantages of easy operation, convenience and speed, saving time, electricity and energy, and improving construction efficiency.
[0004] The technical solution adopted by the present utility model is as follows: the new type of pile foundation sleeve proposed in this solution includes a pile foundation sleeve body, which is composed of an outer sleeve, a locking cone sleeve and an opening cone sleeve. An internal thread structure is provided inside the outer sleeve, and the outer sleeve is threadedly connected to the locking cone sleeve through the internal thread structure. The outer side wall of the locking cone sleeve is provided with an external thread structure that matches the internal thread structure. The locking cone sleeve is threadedly connected to the outer sleeve through the cooperation of the external thread structure and the internal thread structure. One side of the inner surface of the locking cone sleeve and the outer surface of the opening cone sleeve are provided with mutually matching conical surface structures, and the locking cone sleeve and the opening cone sleeve are matched through the set conical surface structure.
[0005] Among them, an internal thread structure is provided inside the open cone sleeve, and the open cone sleeve is engaged and connected with the steel bar through the provided internal thread structure. The open cone sleeve is threadedly connected to the thread head at the end of the steel bar.
[0006] The locking cone sleeve can shrink the inner diameter of the opening cone sleeve, thereby tightening the threads at the ends of the steel bars, so that the two groups of steel bars can form a rigid connection structure.
[0007] Among them, the locking cone sleeve and the opening cone sleeve are used to cooperate to tighten the steel bar joint, so that when the force on the steel bar joint changes, the steel bar shrinks and tightens as the external force increases, thereby increasing the bearing capacity.
[0008] Furthermore, the steel bars can be shrunk and compressed by the provided open cone sleeve, thereby eliminating residual deformation and ensuring a rigidly connected structure of the steel bars.
[0009] Furthermore, the provided locking cone sleeve can be used to tighten the steel bar, thereby causing the open cone sleeve to shrink and improve the fastening of the steel bar.
[0010] The beneficial effects achieved by the utility model using the above structure are as follows: the utility model is a new type of pile foundation sleeve, which has the following advantages: the new type of pile foundation sleeve proposed by the utility model can be used to fix the position of the upper and lower steel bars of the steel cage, so that it can become a steel bar connection structure that cannot rotate with each other; the pile foundation sleeve can simultaneously connect the connection parts of the steel cage, beams, inclined columns, etc. at different angles in fixed positions; the pile foundation sleeve structure can meet all the performance requirements of the existing straight thread connection, and at the same time eliminate the residual deformation of the straight thread connection; the pile foundation sleeve structure is simple, easy to construct and operate, and convenient and feasible.
