Problems solved by technology

The deficiencies of the related technology are: 1. When installing the chevron nut on the C groove of the floor, it is necessary to rely on a molding stool. , after inserting the pull screw, first install the mountain-shaped nut in the C-groove on the floor, and stick it to the inner cavity panel of the C-groove on the floor, so as to ensure that the mountain-shaped nut and the side rib of the C-groove on the floor form a clamping position

Abstract

The invention discloses a unilateral opposite-pull screw system which comprises a unilateral opposite-pull screw. The unilateral opposite-pull screw is composed of a threaded section and a non-threaded section. The threaded section is provided with a connecting thread. The end face of the threaded section is provided with a square groove. One end of the non-threaded section is provided with a square step groove penetrating through the end of the non-threaded section. One end of the non-threaded section is further provided with a screw pin hole penetrating through the square step groove. The axis of the screw pin hole is perpendicular to the opening direction of the square step groove. The non-threaded section is further provided with a pin piece and a pin shaft. The pin piece is provided with a pin piece pin hole. The pin shaft is placed into the screw pin hole and penetrates through the pin piece pin hole. The pin piece can freely rotate around the pin shaft. Compared with the related technology, by adoption of the unilateral opposite-pull screw system, fastening and mounting operation of the inner top of a wall can be omitted, collaborative operation of personnel is reduced, labor intensity of the operators is relieved, and mounting working efficiency is improved; and meanwhile, the template opposite-pull fastening requirement of a small space can further be met.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of building aluminum formwork fastening systems, in particular to a unilateral pull screw system. [0003] 【Background technique】 [0004] According to the fastening system, the aluminum formwork is divided into a pull-tab system and a screw system. For related technologies, see Figure 4 According to the fastening system, the aluminum formwork is divided into a pull-tab system and a screw system. in Figure 4 Middle: K plate 01, mountain nut 02, gasket 03, pull screw 04, exterior wall panel 05, wall body 06, floor C groove 08, operator 09, interior wall panel 10, formwork stool 011, hanging feet Angle aluminum 012. In the screw system, the connection and fastening accessories between the formwork on both sides of the wall 06 are trapezoidal screw, back flute, gasket 03 and mountain nut 02 (arranged in the order of installation), and one screw is equipped with two sets of gaskets and two sets of C...
