Description

one

The invention relates to the construction, in particular to equipment used in the construction of monolithic reinforced concrete industrial, residential and other buildings and structures with the use of reinforced blocks, and is additional to the main ed. St. № 1 101532.

The purpose of the invention is to expand the scope of application by providing the possibility of concreting both frame walls and continuous walls with areas of continuous reinforcement.

FIG. Figure 1 shows the sliding formwork for the erection of structures with the use of reinforced blocks, general view; in fig. 2 - the node in FIG. one; in fig. 3 is a view A of FIG. 2; in fig. 4- a basic scheme for concreting a monolithic reinforced concrete wall with a continuous section and frame frame; in fig. 5 - the same plan; in fig. 6-9 shows the installation scheme of the jacking frame in the process of concreting the structure; in fig. 10 - node I in FIG. 1 (rotated).

Sliding formwork for erection of structures using arm blocks includes a jacking frame consisting of racks 2 symmetrically located on the outer sides of the erected wall 1 and a transverse beam - girder 3 on which jacks 4 are placed. Stands 2 are hung round, 5, working platforms 6 and formwork panels 7.

Through the jacks 4, house-multiple rods 8 are omitted, equipped with stops 9 for suspension to the support head 10 fixed on the armature blocks 1K. The support head 10 is made in the form of a frame, for example, from channels, mounted in such a way that they can be missed between them on the outer sides of the wall 1, the jacking rods 8, the supporting head 10 are provided with symmetrically positioned relative to the axis of the jacking frame fixtures for hanging the jacking frames with brackets 12, one end rigidly fixed on the frame of the supporting head 10, to single ends of which with the help of hinges paired H9 fixed spring-loaded cams 13.

The beam-bolt 3 is provided with stops 14 with screws 15 for giving the cams 13 a starting position. Rigel 3 home506332

multiple frame mounted on racks 2 With the possibility of removal, for example, using the corners 16 and bolts 17.

Racks 2 jackframe frame equipped

5 with an additional section consisting of additional racks 18 mounted on racks 2.

Upper ends of extra racks 1 8 and lower ends, 1 main racks 2

 O are provided with slots for insertion of tie rods 19 fixed in the working position, for example, with screw elements 20 and nuts 21. Sliding formwork for erection (5 of the structures using reinforced blocks works as follows.

After the installation of the first Russ of the armoblocks 11 of the wall to be built 1, the jacking frames are mounted along the wall length

20 of the uprights 2 with the extra posts 1-8 and the deadlocks 3 with the jacks 4. To the uprights 2 they were fastened rounding 5, the working platforms 6 and the shuttering shields 7. The bolt 3 fixed during mounting the frame

25 to the rack with 2 corners 16 and bolts 17 with the possibility of a connector.

On top of the armoblocks 11 above the house, the supporting head 10 is fastened coaxially with them, the plant T30 with the jacking rods 8 is attached to it and suspended by means of the stops 9.

The lower ends of the jacking rods 8 are inserted into the lifting jacks 4 of the formwork and as the concrete is laid, the sliding formwork of the jacking 4 is lifted by the jacks 8 by the jacks 8.

When moving within the height of a solid wall (Fig. 4), the proposed formwork works in the same way as art.

When switching to concreting the frame-frame wall, when it is necessary to simultaneously concrete the pillars 22 and horizontal sections 23 using ready-made reinforcement cages, the formwork works as follows. When, when lifting the formwork, the bolt 3 reaches the horizontal arm-block 23,

50, twisting rods 19 are inserted into the jacking frame system. They are inserted into the grooves of the main 2 and additional 18 racks and fix the position of the latter with the help of screw elements 20 and 21.

Thereafter, the bolt 3 is detached from the uprights 2 and out of the jacking frame. The sliding formwork continues until the concreting of the arm-block 23 is completed. After that, the bolt 3 is re-inserted into the jacking frame, fixed with the help of the angles 16 and the bolts 17, the draw-rods 19 are removed, and the formwork continues.

The scheme of the proposed formwork for the concreting of frame-frame structures shown in Fig, 6-9. YU

In the absence of a frame, but if necessary, concreting of a wall with reinforcement, including bundles of continuous pre-stressed reinforcement 2A, pin 19, At the time that the jacking frames approach the reinforcement beam 24, the transom 3 is pulled out of the frame, the idle form rises to the height corresponding to the reinforcement beam, after as the bolt 3 is inserted into the house-multiple frame and the lifting of the sliding formwork with concreting of the wall structures continues.

When transferring concrete from one wall to the next and replacing jacking rods 8, the jacking frames are placed on the support headwork of the formwork without tightening 15 ke 10, mounted on the armored blocks 11,

rods 19. As the jacking frames approach the reinforcement beam 24, the bolt 3 is withdrawn from the frame, the idle formwork rises to a height corresponding to the height of the reinforcement beam, then the bolt 3 is inserted into the house-fold frame and the sliding of the sliding formwork with concreting wall structures continues.

When transitioning concrete from one wall to another and replacing the jacking rods 8, the jacking frames are illuminated onto the support head.

SLIDING FORMWORK FOR CONSTRUCTION OF CONSTRUCTIONS WITH APPLICATION ARMOBLOKOV, by author. St. No. 1101532, characterized in that, in order to expand the scope of application by providing the possibility of concreting both frame walls and solid walls with continuous reinforcement sections, jack frame racks are equipped with additional sections mounted in their upper part and tie rods for fixing racks installed with the possibility of a connector on the top and additional sections and the bottom of the racks, while the crossbar of the jack paradise is fixed on racks with the possibility of a connector. > TO) 1 I
