Technical Field
The invention belongs to the technical field of building template reinforcement, and particularly relates to a back ridge bending rigidity reinforcing device.
Background
The back edge is generally made of square tubes or aluminum profiles, called steel or aluminum back edge, and is commonly used for reinforcing aluminum templates or templates in other forms.
After the wall and column aluminum formworks are installed, the aluminum formworks are reinforced by using split bolts and back edges so as to resist the lateral pressure of the aluminum formworks when concrete is poured. According to the requirements of national specifications, a plurality of back ridges are vertically arranged on the template, and split bolts are transversely arranged on each back ridge at certain intervals.
For wall formworks, the national specification "technical Specification for Combined aluminum alloy formworks" (JGJ 386-2016) stipulates in section 5.3.1, and the transverse spacing between split bolts is not more than 800 mm. In fact, the performance of the aluminum template and the back edge is higher than the national standard requirement, so the transverse distance between the split bolts is usually properly enlarged in engineering, even reaching 1000 mm. When the cross section of the concrete column reaches more than 350mm, the column template is provided with a back edge and a split bolt.
The back edge is subjected to bending deformation in the horizontal direction due to the lateral pressure of the template during concrete pouring, the larger the transverse distance between the counter bolts is, the more obvious the deformation is, and the deformation control of the template directly influences the concrete forming effect.
In the aspect of wall formwork reinforcement, the split bolts can generally penetrate through the wall body, and occasionally, the split bolts cannot penetrate through the wall body. For the transfinite post, a post cross-sectional dimension is too big, causes the split bolt overlength (according to post size field fabrication), in case have the shaped steel condition in meetting the post moreover, often can't run through the split bolt, and this just brings certain difficulty for the reinforcement of post template.
