Technical Field
The invention relates to edge angle steel arrangement for pouring concrete, in particular to a concrete edge protection angle steel construction method.
Background
In building, metallurgy and municipal engineering, it is a very common practice that concrete adopts angle steel to protect edges, but the angle steel often can lead to the angle steel to warp in the process of being welded with reinforcing steel bars to make into edge-protecting angle steel. The use requirement and the precision requirement cannot be met in some technological processes with higher precision requirements. For example, in large equipment foundations such as stamping pits and measuring stations in automobile engineering, the edge-protecting angle steel of a directly welded steel bar often hardly meets the precision requirement, and the deformation and warpage of the angle steel sometimes occur.

However, the problem of angle steel deformation still occurs when the anchor bars are welded on the narrow surface of the angle steel in the specification and arrangement mode, and the angle steel is difficult to keep straight.
The known edge angle arrangements for cast concrete therefore suffer from the above-mentioned inconveniences and problems.

b. providing a plurality of countersunk head bolts, and enabling the screw rods of the countersunk head bolts to penetrate through the counter bores and the heads of the countersunk head bolts to sink into the counter bores to be attached to the wall surfaces of the counter bores;
c. providing two nuts for each countersunk head bolt, wherein one nut penetrates through a screw rod of the countersunk head bolt to reach the surface of the inner right-angle side width of the angle steel to be matched with the head of the countersunk head bolt to fasten the countersunk head bolt, and the other nut is fastened at the end part of the screw rod of the countersunk head bolt to enhance the anchoring force of the countersunk head bolt and the concrete;
d. and fixing the angle steel on the template by adopting a bracket, and pouring concrete to enable the concrete and the edge-protecting angle steel to form a whole.
The concrete edge-protecting angle steel construction method can be further realized by adopting the following technical measures.
In the method, the angle steel is equilateral angle steel or non-equilateral angle steel.
In the method, the specification of the angle steel is not less than ∠ 75 × 8 mm.
The method is characterized in that the counter bores are arranged linearly on the width of the right-angle side of the angle steel.
