Through-wall bolts generally use round steel bolts with wires on both ends, also known as pull bolts. There are also flat steel bolts with long holes at both ends and wedge-shaped iron inserted into the fixed wedge
Installation method
1. First lift the Yin and Yang angle molds to the job site and put them in place.
. Lift the formwork to the installation location in order according to the order of installation of horizontal walls first and then vertical walls. According to the number (large formwork should be numbered and there will be an assembly plan on site), use a crowbar to adjust the formwork in place according to the wall line. Install the wall bolts, adjust the formwork and anchor screws symmetrically, use a magnetic line pendant to use the form support auxiliary line to adjust the verticality of the formwork, and adjust the upper opening of the formwork with a wire, and then tighten the anchor screws and wall bolts.
. Install the exterior wall formwork. Place the formwork on the metal triangular platform frame. Put the formwork in place and fasten and correct it with bolts. Pay attention to that the connections at the construction joints must be tight, strong and reliable to prevent misalignment and slurry leakage. .
. Check whether the joints between the corner formwork and the wall formwork, and between the corner formwork and the wall formwork are tight. If not, use foam sponge to fill the gaps to make them tight and prevent slurry leakage, misalignment and other phenomena.
Before setting up the formwork in the elevator shaft, the working platform should be hoisted into the elevator shaft. The primary and secondary keels and steel legs of the working platform should be channel steel. The distance between the keels should be appropriate and welded and fixed, and then thick wooden boards should be laid on it. After the platform is in place, adjust the four corners to make the platform level.
Lift into the cylinder mold, open the mold according to the axis, correct the verticality, and tighten the wall bolts.
After all formwork installation and adjustment are completed, pre-inspection and acceptance of the formwork project can be carried out before concrete can be poured.
The triangular supports of the large formwork should be symmetrically distributed on both sides of the formwork.
. The connection between the large formwork and the large formwork should be no less than five through-wall bolts. The connection between the external angle formwork and the large formwork should be no less than five bolts. The internal angle formwork should be equilateral and should be connected to the large formwork by no less than three diagonal ties. , the non-equilateral formwork should be bolted to the large formwork, with no less than five bolts on each side.
. At the connection between the yin and yang angle formwork and the large formwork, in order to prevent the concrete from being staggered, steel bars should be added to the tongues and grooves in the formwork.
