Dismountable and cramped small-baked formwork

The technical solution relates to the construction of z can be used when Bozvedeniv monolithic reinforced concrete buildings with a cellular structure, such as garazai, vegetable stores, etc.

O1ga is known. for the construction of monolithic reinforced concrete buildings with a cellular structure, mainly garages (AS USSR I76533I, E04G 11/00, published on 09/30/92), including shuttering boards of walls and ceilings, which are seamlessly interconnected z forming an all-metal casing, which is the base is equipped with a running gear in the form of runners. Stripping is carried out by pulling the formwork body out of the cell on the runners using a rod connected by means of an anchor to the end shield. Such formwork requires the use of heavy vehicles, such as a tractor, which is not always cost-effective.

The closest io technical rigidity is a collapsible gelcable formwork (AS USSR 992706, Sji4G 11/02, publ. 30.01.83}, which includes STILL walls and ceilings, supporting elements for panels B in the form of a system of racks with telescopic frames connected by uesi j are connected by telescopic joints with the fixer and lengths, as well as by external corner (side) elements, connecting vertically the joints of the corners of the wall formwork and horizontally the joints of the corners of the wall panels with the ceiling panel.

Tasal formwork has a rather complicated design of the supporting elements of the panels, requiring considerable labor for assembling and disassembling them during the construction process.

the creation of the ACOGENITY of the simultaneous concrete construction of several cells of the building with a heavy-duty construction.

The task is carried out due to the fact that in the formwork containing wall shields and overlapping, supporting elemental for 1TS2TOV to the onboard, it is proposed that the supporting elemental elements be EXECUTED in the form of metal frame elements, one of which is placed along the perimeter of the base of the internal walls of a separate cell, while the frame elements placed simultaneously in several neighboring cells and connected between themselves, as well as in the form of metal longitudinal elements placed along the base of the outer walls of the said cells and Inonii with frame members, and each separate element bootovoy yacheykiteazmeschen perimeter seam panels overlap with wall schitash.perpendikulyarno

At the same time, the frame elements at the base of the inner walls of the cells are connected between, along with themselves and with the longitudinal elements at the base of the outer walls of the cells,

And each metal core element at the base of the inner walls of the cell is made collapsible in the form of segments connected by inserts.

The design of the formwork is illustrated by the attached drawings. In FIG. depicts a plan view of the placement of internal frame and external longitudinal supporting shields of elements for two cells; on (- a plan view of the placement of the shield of the formwork of souls of two cells; on Fig. 3 - a top view of the placement of the floorboards with side elements for two cells; on o; ig. 4 - a section along A - A of one cell.

The formwork includes meteillic frame elements I laid at the base of the internal walls of several cells, consisting of segments connected by inserts 2, m longitudinal metal elements laid at the base of the external walls of the building 3. Frame elements I of adjacent cells are connected between the casing 4, and shadow E; itam

with the same: f junction elements I are connected to the longitudinal elements 3 B of the base of the rising walls. On the supporting railing elements I, stacked panels of three profiles are fixed: ordinary panels 5 and corner panels 6 and 7, forming the formwork of the inner walls of the cells. On supporting longitudinal elements 3, ordinary shields 5 and 8 are attached, forming the formwork of the exterior walls of the building. Overhead shields 9, connected by each other, rest on beams 10 laid with support on wall panels 1-1 of cells. An airborne element II is attached to the wall boards of the GL along the perimeter of their junction with the floor shields 9. perpendicular)

Installation of formwork and concrete pouring of the walls of the building is as follows. On the terrain with the layout of the plan of the future structure of the multi-cell structure, a supporting formwork base is installed for several cells: first, several (at least two) frame elements I, consisting of metal segments of a C-shaped profile, connected together insert W / 1 and 2, and then on both outer sides of the cells into the base. Longitudinal elements 3 of metal strips of a C-shaped profile are laid. All frame elements I and longitudinal elements 3 are fastened to each other with ties 4, for example, in the form of 1 nails with nuts screwed on both sides. On the bases of the frame elements I, wall shields 5,6 and 7 of the internal opal bq are installed, and on the bases of the longitudinal elements 3, solid wall shields 5 are installed on one side of the building, and wall shields 8 with openings on the other side of the building (from the facade) for cell doors (see Fig. 2). All wall panels are fastened together and attached to the supporting elements I and 3 using, for example, hinges and wedges or other similar means of connection. At the level of peekshtiya mounted interconnected shields 9 overlap 6/06

tiy cells. And on the upper end face of the perimeter of the wall BRUSHES of each cell, an onboard element II in the form of a metal strip is fastened, fastening the wall boards from above and ogresch; yavaya space for pouring concrete mixture on the formwork of the ceiling. Simultaneously with the assembly of the formwork, the fittings are installed in the wall space. Upon completion of the installation of several cells, the concrete mixture is poured into the formwork of the walls and floors. After a sufficient strength of concrete is set, the flashing of the flask is carried out in the following order: the side elements II, beams 10 and boards 9 of the shuttering floors are removed; inserts 2 are removed from the frame elements I, the ties 4 are removed, after which the supporting base element is completely dismantled - the internal frame elements I and the outer longitudinal elements 3, and then all the wall panels 5, b, 7 and 8 of the depth section are unfastened and removed. And the process is repeated during the construction of the following cells of the building. The author is the applicant, (v. V. Kharin A.P.
