Description

(54) METHOD OF MANUFACTURING ARMATURE FRAMEWORKS

one

The invention relates to methods for manufacturing reinforcing cages of reinforced concrete columns, preferably with embedded parts and intermediate rods.

A known method of manufacturing reinforcing cages of long-dimensional reinforced concrete products, including the installation and fixing in collapsible templates of longitudinal rods, fixing on the transverse shtangah embedded parts arrangement and securing the transverse elements of the frame D.

The disadvantage of this method is the difficulty of fixing the assembled frame elements and the possibility of installing only the end parts.

Closest to the proposed invention is a method of manufacturing reinforcing cages of columns, including the installation of longitudinal angular and intermediate, for-; fastening of angular rods and tartsoKOLONN

out clamps, placement of collars and their fastening at intersections with longitudinal rods, installation and fixing of embedded parts

The disadvantage of this method is the need for assembling embedded parts only at the posts of assembling frameworks, where it is impossible to use a conductor to fix the elements of embedded parts, which reduces the productivity of reinforcing frameworks.

The purpose of the invention is to improve the production performance of reinforcement cages.

For this, in the method and the production of reinforcement cage columns, including the installation of longitudinal corner and intermediate rods, securing the corner rods in the end clamps,

Claims (2)

The arrangement of the clamps and their fastening at the intersections with the longitudinal rods, installation and fixing of embedded parts, after placing 3 mutes between the longitudinal corner beads, install temporary struts, which are arranged in pairs in mutually perpendicular directions, then fasten the clamps with the angular rods the fixed parts are fixed and the temporary struts are removed, then a support is placed under the center of gravity of the frame, the corner rods are released from fastening in the end clamps, the frame is turned y axis of the support in a horizontal plane to exit its ends beyond the clamps, and then introduced into the frame and fixed in intermediate longitudinal rods. FIG. 1 shows a stand for mounting reinforcing cages with longitudinal corner rods fixed in the end clamps; in fig. 2 - that. after the arrangement of clamps and preparation for installation of embedded parts in FIG. 3 shows section A-A in FIG. 2; in fig. 4 - stand after installation of embedded parts in the card; in fig. 5 is a section BB in FIG. four; in fig. 6 stand after installation under the support frame; in fig. 7 is a view of B in FIG. 6; in fig. 8 - the same after turning the frame around the support; in fig. 9 - the same after the installation of longitudinal spaced rods; in fig. 10 is a view of FIG. 9. The manufacture of reinforcement cages is carried out as follows. The longitudinal corner rods 1 put a stack of clamps (not shown in the drawing) and put them on the table 2, previously lifted to its upper position by means of the drive 3. Then the corner rods are fixed in the stationary side of the sim 4 and under the sliding clip 5, they distribute clamps 6 along the length of the rods (Fig. 2), between the latter, horizontal spacing 7 and perpendicular to it - vertical strut 9 are inserted, fixing the longitudinal rods in the corners of the clamps (Fig. 2 4). After that, the intersections formed by the longitudinal rods And clamps are fastened, the roller 2 is lowered, the inserts 9 (fig. 2) are installed on it, and the table is raised to the upper position, the parts are inserted into the frame, i.e. between the longitudinal rods and clamps, fasten the parts to the clamps or to the longitudinal rods. Then the spacers 7 and 8 are removed from the rigid frame, the table is lowered, the support 10 is placed on it, by raising the table to the upper position under the center of the body frame tin (Fig. 6). After that, the frame is freed from the end clips 4 and 5 (Fig. 6 and 7), it is turned in a horizontal plane so that the ends of the frame are displaced beyond the clips. Through the free ends of the frame pass the intermediate longitudinal rods 11 1 FIG. 8-10), which are fastened to the clamps and flat elements of the embedded parts. The finished reinforcement cage is removed from table 2, after which another reinforcement cage is manufactured. Claims The method of making reinforcement cage columns, including the installation of longitudinal corner and intermediate rods, securing the corner rods in the end clamps, aligning the clamps and fastening them at the intersections with the longitudinal rods, installing and securing the fixings, in order to increase performance, after placing the clamps between the longitudinal corner rods, install temporary struts which are arranged in pairs in perpendicular directions. x, then fasten the yoke. with corner rods, fix the fixings and remove the temporary spacers after that, under the center of gravity of the frame, the support is supplied, the corner rods are released from the attachment in the end clamps and the frame is turned around the support in the horizontal plane until its ends extend beyond the clamps, after which they are inserted into the frame and the longitudinal intermediate rods are fixed.
