Problems solved by technology

The disadvantage of this method is that the diameter of the bolt is large (28mm or 32mm, etc.). After the formwork is removed, the bolt hole diameter is large, and the workload to be filled is large, and it affects the quality of the concrete surface, especially for walls and panels that require the appearance of fair-faced concrete. , beams and other structural surfaces, the requirements are more stringent, and it is more difficult to meet the requirements by means of pulling bolts

Embodiment Construction

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

[0013] Depend on figure 1 and Figure 4 It can be seen that, firstly, lubricating oil 9 is applied to the surface of the steel strand 8, and then the sheath 10 is put on, and then one end thereof is inserted into the backing plate 1, the tensioning sleeve 2, the anchor tube 3, the clip 5, and the extrusion sleeve 4 in sequence. , tighten the anchor tube 3 and the extruding sleeve 4, make the clip 5 clamp the tensioned steel strand 6, and pass the other end into the tensioned hole of the template 7, repeat the above procedure, and place the tensioned steel strand 6 in another After the anchoring system at one end is installed, the tensioning sleeve 2 is twisted to tighten the tensioned steel strands to withstand the lateral pressure on the formwork system when pouring concrete. When the formwork is removed, the anchor system is first loosened and unscrewed, and then t...

Abstract

The invention relates to a large formwork oppositely-drawing steel strand, which has the main technical characteristic that a large formwork oppositely-drawing steel strand consists of a large formwork, an anchoring system and a steel strand, and is characterized in that the oppositely-drawing steel strand passes through the large formwork, and two ends of the steel strand are fixed and tightened by the anchoring system. The anchoring system comprises a liner plate, a tensioning sleeve, an anchor cylinder, an extrusion sleeve and a clamping piece, wherein the tensioning sleeve is fixed on the liner plate. After the large formwork is mounted and positioned, the oppositely-drawing steel strand with a jacket passes through the oppositely-drawing hole on the large formwork to fasten the anchoring system on one side of the large formwork on one end of the steel strand first and then fasten the anchoring system on the other side on the other end of the steel strand, and the steel strand is tightened and the anchoring system is screwed down. Compared with the prior oppositely-drawing bolts, the oppositely-drawing steel strand can reduce the oppositely-drawing aperture, reduce the repairing quantity and the impression defects on the concrete surface, and improve the repairing working efficiency.

Description

Technical field: [0001] The invention relates to a large formwork double-tension load-bearing system, in particular to a large formwork double-tension steel strand. technical background: [0002] At present, my country's construction enterprises mainly use pull bolts for large formwork such as shear walls. The disadvantage of this method is that the diameter of the bolt is large (28mm or 32mm, etc.). After the formwork is removed, the bolt hole diameter is large, and the workload to be filled is large, and it affects the quality of the concrete surface, especially for walls and panels that require the appearance of fair-faced concrete. , beams and other structural surfaces, the requirements are more stringent, and it is more difficult to meet the requirements by means of pull bolts. Invention content: [0003] The present invention aims at the deficiencies in the above-mentioned technologies, and provides a large formwork double-stretched steel strand, which can not only ...
