Problems solved by technology

[0002] In the foundation pile construction, the phenomenon of pile connection will occur due to various factors. In most cases, the weldability of the metal end plate of the pile body is used to weld the two end plates with electric welding after the pile body is aligned. In general, there is no problem, but due to geological conditions and various phenomena, in some areas where the buoyancy of groundwater is large and the groundwater is highly corrosive to the welding surface, this connection method by electric welding cannot meet the architectural design requirements

Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the drawings.

[0013] Such as figure 1 As shown, a single-nut seat assembly type anti-pulling joint includes a square end plate 1 and two nut holders 2 arranged on each side of the back of the end plate 1, all the nut holders 2 have openings facing outward , An anti-rotation connecting plate 3 is connected between two adjacent nut seats 2 on two adjacent sides. The two ends of the anti-rotation connecting plate 3 are respectively welded to the bottom ends of the two nut seats.

[0014] Wherein, the anti-rotation connecting plate 3 can be two pieces, one end of each plate is fixed to the bottom end of the nut base 2, and the other end is fixed to the other plate for welding; the included angle between the two anti-rotation connecting plates 3 is 90°; the anti-rotation connecting plate 3 can also be a steel plate bent at a right angle.

[0015] The two ends of the anti-rotation connecting plate 3 are we...

Abstract

The invention discloses a single nut seat assembly type pulling-resistant joint, which comprises a square end plate and nut seats. Each edge of the back surface of the end plate is welded with two nut seats, openings of the nut seats face outwards, and a rotation-preventive connecting plate is connected between the two adjacent nut seats on each two adjacent edges. The single nut seat assembly type pulling-resistant joint has the advantages that two pulling-resistant piles are additionally connected, connecting torque which is weakened by damage to an original welding joint of the two pulling-resistant piles can be increased, accordingly, tensile strength and bending resistance of a space between two end plates can be improved, and performances of the integral piles are enhanced.

Description

Technical field [0001] The invention relates to an anti-pull pile, in particular to an assembled anti-pull joint with a single nut seat. Background technique [0002] In the construction of foundation piles, there are many factors that will cause pile connection. In the process of pile connection, the weldability of the metal end plate of the pile body is used in most cases. After the pile body is aligned, the two end plates are welded together by electric welding. Under normal circumstances, there is no problem. However, due to various geological conditions, when the groundwater is buoyant and the local sewage is corrosive to the welding surface, this method of electric welding connection cannot meet the architectural design requirements. Summary of the invention [0003] Objective of the invention: In order to overcome the shortcomings of the prior art, the objective of the present invention is to provide a single-nut seat assembled pull-out joint which can improve the tensile s...
