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 described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a single nut seat assembled anti-pull joint, including a square end plate 1, and two nut seats 2 arranged on each side of the back of the end plate 1, all the openings of the nut seats 2 are facing outwards , An anti-rotation connecting plate 3 is connected between two adjacent nut seats 2 on adjacent two sides. The two ends of the anti-rotation connecting plate 3 are respectively welded to the bottoms of the two nut seats.

[0014] Wherein, the anti-rotation connecting plate 3 can be two pieces, one end of each plate is fixed on the bottom end of the nut seat 2, and the other end is fixed on another 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 into a right angle.

[0015] The two ends of the anti-rotation connectin...

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 a pullout pile, in particular to a single nut seat assembled type pullout joint. Background technique [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. Generally speaking, there is no problem, but due to geological conditions and various phenomena, in 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. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a single nut seat assembled pullout joint that can improve the tensile strength and ben...
