Abstract

The invention relates to construction. The goal is to increase ease of assembly and disassembly. The formwork for concreting the foundations for the columns consists of formwork blocks 1 and 2 and the shoe part of the column 3. The blocks are coaxially placed relative to each other. The connection of the blocks is carried out by means of the separators 4 and 5 and detachable clamps. A racking-off device 10 is used for stripping, which is associated with flare 4.

Description

The invention relates to the structure and is intended for use in the construction of foundations for columns.

The aim of the invention is to improve the ease of installation and dismantling of formwork.

FIG. 1 shows a formwork, a general perspective view; figure 2 - the same, with the emptying of the glass under the concrete column; fig.Z - the same, with the conductor dp installation of anchor bolts under the steel column in figure 4 - the same, in the transport position. I

The formwork for concreting the foundations for the columns consists of formwork blocks 1 and 2 of the shoe part and block 3 of the sub-column. The number of blocks can be increased or decreased if necessary. Formwork units 1–3 are placed coaxially one in the other with the possibility of vertical movement and consist of shields connected in a rigid structure, in which at least one pair of opposite side faces is made with separations. The flap 4 is folded outward, and the flange 5 is folded into the inside of the blocks. At the junctions of blocks 1 and 2, as well as blocks 2 and 3, flanges A and 5 are detachably fixed. To do this, the flanges 4 have lugs 6 in which the sockets for the wedge 7 and the transport holes 8 are wired, and the flanges 5 have sockets 9 for engagement with the lugs 6. At the flanges 5, a stripping device is mounted in the form of a nut and a stop screw 10, acting on the flap 5, placed under the flare 5i For the sub-column block 3, which does not have an inner block, from the bottom flange 11, the plate 12 or frame, which is affected by the stripping unit of the block 3, is movable. tim Transport blocks 1-3 to date are provided with a limiting stop 13 which performs the function zhekosti ribs.

The formwork is used as follows.

At the place of concreting, the formwork enters the transport position.

3, with the help of a lifting mechanism, lift until the flanging 4 blocks 2 and 3 of the short-circuit are closed with flanging 5 blocks 1 and 2, and lugs 6 enter the slots 9. Then a wedge 7 is inserted into the slots of the eyes 6 and fixes 1-3 relative to each other .. Formwork set into place, concreting the foundation, covering it with pre-assembled reinforcement cage. The frame can be assembled separately or temporarily attached to the formwork and fed to the site of concreting together with the formwork. Depending on the type of columns, a hollow core 14 or a jig 15 of known construction may be mounted on the formwork (Figures 2 and 3). The concrete is then cast and compacted with a vibrator. After solid. Deni concrete opyubku removed. To do this, starting from the bottom block 1 of the shoe part, knock out a wedge 7 and rotate the stop screws 10, abutting the flange 4 of the block 2, tear off the block 1 from the concrete. Similarly, blocks 2 and 3 are torn off.
