Tower foundation nut connecting piece construction structure

Abstract

The utility model discloses a tower foundation nut connecting piece construction structure. The tower foundation nut connecting piece construction structure comprises a limiting mechanism which is composed of three limiting strips distributed in a triangular mode and can abut against a nut to prevent rotation and achieve limiting. The limiting mechanism for preventing rotation limiting of the nut is formed by fixing the three limiting mechanisms on the positioning plate in a triangular distribution mode, so that the components of the limiting mechanism are single in shape, the number of the components is small, and the problem that in the prior art, due to the fact that a limiting mechanism comprises a screw, a spring, an installation frame, an adjusting wheel and a limiting strip, installation is tedious due to too many components is solved.

Description

Technical Field

[0001] This utility model relates to a construction structure for a tower foundation nut connector, in the field of tower foundation construction technology. Background Technology

[0002] After the tower foundation is tied with reinforcing bars, pre-embedded threaded rods need to be placed inside the reinforcing bars. To ensure the spacing between the threaded rods, a positioning plate needs to be installed on the top of the threaded rod. The positioning plate is pressed down by the screw nut on the threaded rod to limit the movement. Limiting is necessary to prevent the nut from shifting on the threaded rod.

[0003] The existing nut limiting technology is available in Chinese Patent Publication No. CN212672199U. Although the nut can be prevented from rotating by the limiting mechanism, the limiting mechanism for the nut includes a screw, spring, mounting bracket, adjusting wheel and limiting strip. The excessive number of components in the limiting mechanism leads to complicated installation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a construction structure for tower foundation nut connectors.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a construction structure for a tower foundation nut connector, comprising:

[0007] It is a limiting mechanism consisting of three limiting bars arranged in a triangle, which can hold the nut in place to prevent rotation and thus limit its movement.

[0008] Includes: a threaded rod pre-embedded in the steel reinforcement, a positioning plate fitted on the top of the threaded rod, a nut screwed into the top of the threaded rod extending through the positioning plate, and the nut screwed onto the threaded rod to press down on the positioning plate;

[0009] The positioning plate is equipped with a limiting mechanism to prevent the nut from rotating and to limit its position. The limiting mechanism consists of three limiting strips that are arranged in a triangular pattern and welded and fixed to the positioning plate. The limiting strips are welded and fixed to each other near their ends. The three limiting strips arranged in a triangular pattern hold the nut in place to prevent it from rotating and thus limit its position.

[0010] It also includes the tower foundation, which has reinforced steel bars.

[0011] The bottom of the screw is spot-welded to the reinforcing steel body for fixation.

[0012] The lower part of the positioning plate is equipped with a bottom support rod to support the positioning plate upward.

[0013] The bottom support rod is fixed with vertical support rods at both ends. The vertical support rods are two rods that support the tower foundation distributed on the inner and outer diameter surfaces of the positioning plate.

[0014] The beneficial effects of this utility model are as follows: the limiting mechanism for preventing the nut from rotating is composed of three triangularly distributed components fixed on the positioning plate, which makes the limiting mechanism components simple in shape and fewer in number. This solves the problem of excessive components and complicated installation in the existing limiting mechanism, which includes screws, springs, mounting brackets, adjusting wheels and limiting strips.

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 2 As shown.

[0020] This application discloses a construction structure for a tower foundation nut connector, comprising:

[0021] The steel reinforcement 2 is located on the tower foundation 1. The steel reinforcement 2 is tied into a circle and located on the tower foundation 1.

[0022] A screw rod 3 is pre-embedded in the reinforcing bar 2. The bottom of the screw rod 3 is spot-welded to the reinforcing bar 2. The top of the screw rod 3 has a positioning plate 4. The positioning plate 4 has a through hole for the top of the screw rod 3 to pass through. The positioning plate 4 is composed of multiple plates assembled and fixedly connected by welding seam 41.

[0023] A nut 5 is screwed onto the top of the screw 3 that passes through the positioning plate 4, and the nut 5 is screwed onto the screw 3 to press down on the positioning plate 4.

[0024] The positioning plate 4 is equipped with a limiting mechanism 6 to prevent the nut 5 from rotating and to limit its movement. The limiting mechanism 6 consists of three limiting strips 61 arranged in a triangular pattern and welded and fixed to the positioning plate 4. The limiting strips 61 are welded and fixed to each other near their ends. The three limiting strips 61 arranged in a triangular pattern hold the nut 5 in place to prevent it from rotating and thus limit its movement.

[0025] Since the limiting mechanism 6, which prevents the nut 5 from rotating, is composed of three triangularly distributed rods fixed on the positioning plate 4, the limiting mechanism 6 has a simple shape and a small number of components. This solves the problem of excessive components and complicated installation in existing limiting mechanisms, which include screws, springs, mounting brackets, adjusting wheels and limiting strips.

[0026] A bottom support rod 71 is installed at the lower part of the positioning plate 4. Vertical support rods 72 are welded and fixed to both ends of the bottom support rod 71. The vertical support rods 72 are two rods that are distributed on the tower foundation 1 on the inner and outer diameter surfaces of the positioning plate 4. The bottom support rods 71 ​​are fixed to the vertical support rods 72 to obtain a supporting foundation for the positioning plate 4 to provide upward support.
