Dorsal bar flexural rigidity reinforcing device

Abstract

The invention discloses a dorsal bar flexural rigidity reinforcing device which comprises a positioning block, a screw rod, a first connecting rod, a second connecting rod, a support rod, a U shaped connecting rod, a nut, a T shaped bolt and a pored pin; the first connecting rod comprises a rod A and a rod B hinged to each other and a first pored pin; the second connecting rod comprises a rod C and a rod D hinged to each other and a second pored pin; the screw rod is sequentially arranged in a through hole and an internal threaded hole in a penetrating manner; the screw rod and the second pored pin are in threaded connection; the distance between the first pored pin and the second pored pin can be adjusted through rotating the screw rod; the two ends of the first connecting rod and the second connecting rod are hinged to a positioning block and a U shaped connecting rod; a support rod is hinged to the two ends of the U shaped connecting rod; the first end of the support rod is hinged to the U shaped connecting rod; the second end of the support rod is hinged to a T shaped bolt through the pored pin; the thread end of the T shaped bolt is mounted in the hole of the pored pin in a penetrating manner; and the nut locks a dorsal bar between the nut end of the T shaped bolt and the support rod.

Description

technical field [0001] The invention belongs to the technical field of reinforcement of building templates, and in particular relates to a device for strengthening the bending rigidity of back corrugated. Background technique [0002] The back flute is generally made of square tube or aluminum profile, called steel or aluminum back flute, and is often used to reinforce aluminum formwork or other forms of formwork. [0003] After the aluminum formwork of the wall and column is installed, it must be reinforced with pull bolts and back ribs to resist the lateral pressure on the aluminum formwork when pouring concrete. According to the requirements of the national standard, the formwork is arranged with several back flutes vertically, and each back flute is horizontally arranged with tension bolts at a certain interval. [0004] For wall formwork, Section 5.3.1 of the national standard "Technical Regulations for Composite Aluminum Alloy Formwork" (JGJ386-2016) stipulates that t...

AI Technical Summary

Problems solved by technology

[0006] In terms of wall formwork reinforcement, the pull bolts can generally penetrate the wall, and occasionally there are cases where the pull bolts cannot be penetrated

For overrunning columns, the section size of a column is too large, resulting in too long tension bolts (made on site according to the size of the column), and once there is steel in the column, the tension bolts often cannot penetrate, which is the reason for the column formwork. Reinforcement poses certain difficulties
