Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cap connection pieces, in particular to a pile and cap connection structure. Background Art
[0002] For the construction of the cap on the top of the pile, steel rods are arranged when the pile body is cast. For example, the connection method between the pile and the cap in the National Building Standard Design Atlas (23G409) (the pile top elevation is 5-3 higher than the pile top design elevation) is specified. Steel rods extending out of the pile body are left above the size of the pile body casting for the cap casting. In order to ensure the architectural design strength of the cap, steel rods of standard length are left, and a concrete protective layer needs to be poured on top of the steel rods when the cap is cast.
[0003] Now, in order to meet the requirements of architectural design, reduce the length of the steel rod extending out of the pile body, reduce the pouring of concrete, and save construction resources, we propose a pile and foundation connection structure. Utility Model Content
[0004] The purpose of the utility model is to provide a pile and cap connection structure to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pile and pedestal connection structure, including a steel rod connecting sleeve, a steel rod and a screw rod, the top of the steel rod connecting sleeve is provided with an end plate, the bottom of the steel rod connecting sleeve is provided with a fixing ring, the inner wall of the steel rod connecting sleeve is provided with an internal thread, the bottom of the screw rod is provided with an arc groove, the top of the screw rod is provided with a groove, and the top of the steel rod is provided with a pier head.
[0006] Furthermore, the steel rod passes through the steel rod connecting sleeve and the fixing ring.
[0007] Furthermore, the external thread on the surface of the screw rod cooperates with the internal thread provided on the inner wall of the steel rod connecting sleeve, and the arc groove provided at the bottom of the screw rod cooperates with the pier head provided at the top of the steel rod.
[0008] Furthermore, the groove is configured as a regular hexagon, and the groove is located at the exact center of the top of the screw.
[0009] Furthermore, the fixing ring is fixedly connected to the inner wall of the steel rod connecting sleeve.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the screw is screwed into the steel rod connecting sleeve, and the screw is tightened. The arc groove arranged at the bottom of the screw will support the pier head arranged at the top of the steel rod, and the steel rod connecting sleeve is fixed to the top of the steel rod. An end plate is arranged at the top of the steel rod connecting sleeve, which indirectly increases the area of the steel rod and the building concrete. During the construction of the pedestal, the length of the steel rod left at the top of the pile body is reduced while ensuring the building strength of the pedestal, and the volume of the pedestal is reduced, thereby correspondingly reducing the use of concrete and saving construction resources. In addition, an end plate is arranged at the top of the steel rod connecting sleeve, and the thickness of the protective layer left at the top of the pedestal can also be reduced on the premise that the building design is met.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0017] See also Figure 1-4The utility model provides a technical solution: a pile and a cap connection structure, including a steel rod connection sleeve 1, a steel rod 2 and a screw rod 4, an end plate 3 is arranged on the top of the steel rod connection sleeve 1, a fixing ring 5 is arranged on the bottom of the steel rod connection sleeve 1, an internal thread 6 is arranged on the inner wall of the steel rod connection sleeve 1, an arc groove 7 is arranged on the bottom of the screw rod 4, a groove 8 is arranged on the top of the screw rod 4, and a pier head 9 is arranged on the top of the steel rod 2. When the pile body is poured, the steel rod 2 is first passed through the steel rod connection sleeve 1 and the fixing ring 5 from top to bottom. After the pile body is poured and solidified, the cap is poured, and the screw 4 is installed into the steel rod. The connecting sleeve 1 is inserted into the screw 4, and the screw 4 is rotated through the groove 8 set at the top of the screw 4 using the hexagon socket to make the screw 4 screwed into the steel rod connecting sleeve 1, and the screw 4 is tightened. The arc groove 7 set at the bottom of the screw 4 will support the pier head 9 set at the top of the steel rod 2, and the steel rod connecting sleeve 1 is fixed to the top of the steel rod 2. An end plate 3 is set on the top of the steel rod connecting sleeve 1, which indirectly increases the area of the steel rod 2 and the building concrete. During the construction of the foundation, the length of the steel rod 2 left at the top of the pile body is reduced while ensuring the strength of the foundation. The volume of the foundation is reduced, thereby correspondingly reducing the use of concrete and saving construction resources.
[0018] Among them, the steel rod 2 passes through the steel rod connecting sleeve 1 and the fixing ring 5, and the steel rod connecting sleeve 1 is fixed on the top of the steel rod 2. When the cap is poured, the steel rod connecting sleeve 1 and the end plate 3 arranged on the top will increase the contact area between the steel rod and the poured concrete, so that the cap meets the architectural design requirements while reducing the length of the steel rod and the amount of concrete used;
[0019] The external thread on the surface of the screw rod 4 matches with the internal thread 6 provided on the inner wall of the steel rod connecting sleeve 1, and the arc groove 7 provided at the bottom of the screw rod 4 matches with the pier head 9 provided at the top of the steel rod 2. After the screw rod 4 is screwed into the steel rod connecting sleeve 1, the top of the arc groove 7 provided at the bottom of the screw rod 4 meets the pier head 9 provided at the top of the steel rod 2;
[0020] The groove 8 is set to be a regular hexagon, and the groove 8 is located at the center of the top of the screw 4. The screw 4 is rotated by inserting the hexagon into the groove 8;
[0021] The fixing ring 5 is fixedly connected to the inner wall of the steel rod connecting sleeve 1 .
[0022] Working principle: when pouring the pile body, first make the steel rod 2 pass through the steel rod connecting sleeve 1 and the fixing ring 5 from top to bottom. After the pile body is poured and solidified, the cap is poured, the screw 4 is installed into the steel rod connecting sleeve 1, and the screw 4 is rotated through the groove 8 set at the top of the screw 4 using the inner hexagon, so that the screw 4 is screwed into the steel rod connecting sleeve 1, and the screw 4 is tightened. The arc groove 7 set at the bottom of the screw 4 will support the pier head 9 set at the top of the steel rod 2, and the fixing ring 5 will support the bottom of the pier head 9, and the steel rod connecting sleeve 1 is fixed to the top of the steel rod 2. An end plate 3 is set at the top of the steel rod connecting sleeve 1, which indirectly increases the area of the steel rod 2 and the building concrete. During the construction of the cap, the length of the steel rod 2 left at the top of the pile body is reduced while ensuring the strength of the cap. The volume of the cap is reduced, thereby correspondingly reducing the use of concrete and saving construction resources. In addition, an end plate 3 is set at the top of the steel rod connecting sleeve 1, and the thickness of the protective layer left at the top of the cap can also be reduced on the premise that the architectural design is met.
