Description

The invention relates to monolithic construction and can be used to erect all the structures of buildings and structures on a technological gripper in one technological cycle, including closed cells (four walls and a ceiling), and can also be used as a formwork screen for shotcrete technology.

The known construction of a volumetric climbing formwork includes a supporting frame and a deck and makes it possible to erect three internal walls and overlapping open cells of buildings in one technological cycle.

Closest to the technical nature is volumetric climbing formwork, including a supporting frame of racks and beams with a deck fixed to it for forming walls and ceilings of open cells of buildings.

A disadvantage of the known designs is their considerable metal consumption, cumbersomeness, complexity of manufacturing, considerable time spent by machine tools for mounting and dismantling formwork, the inability to carry out external walls together with the internal ones, as well as technological rigidity.

The objective of the invention is to create a volumetric climbing formwork, which allows to simultaneously erect internal and external walls and floors of buildings and structures, to reduce the metal consumption of the formwork, to exclude the use of lifting mechanisms for mounting and dismantling the formwork, to use non-removable thin-walled flat and decorative formwork, as well as to eliminate the dependence of space-planning decisions of buildings and structures on the design of the formwork and its size.

This problem is solved by making the lattice supporting frame of the closed cell of the building from folding unit frames and inserts joined by transformable docking elements, which, after concreting, are folded into compact packages that can be removed through door or window openings without lifting mechanisms.

The technical effect of the transformation of the supporting formwork frame is achieved due to the fact that the lattice supporting frame is made in the form of a three-dimensional structure consisting of block frames, including two wall and L-shaped ceiling gratings pivotally connected to each other70

cu, or frames of inserts, including a wall and L-shaped ceiling grid, hingedly connected to each other, or of a combination of frames of blocks and inserts, and the frames of blocks and inserts are made to move them to another technological gripper when folding into a bag, the dimensions of which are smaller the size of the doorway, as well as due to the fact that the deck can be hung on the frame with its edges adjoining the door and window openings, at the installation site of which the frame racks can be made removable, while a new insert unit lattice and may be provided with koleSZ LEE.

In the interchangeable formwork, the deck can be made of non-removable cement-bonded or fiberboard or erbolite plates, or decorative reinforcing concrete or fiberglass concrete panels, and the deck can be made in the form of a screen for spraying concrete walls and floors, frame blocks and inserts can be equipped with a spatial telescopic supporting opera, while an element for molding can be installed at the junction of the vertical and horizontal parts of the L-shaped grating and cornice.

This embodiment of interchangeable formwork allows for the flexibility of space-planning solutions, buildings and structures, and it is also not necessary to link cell sizes with the modular dimensions of the formwork. In the case of using a fixed deck, it is possible to use non-traditional local materials as wall cheap materials without surface treatment.

Formwork due to the transformation of block frames and inserts into the bag does not require large storage areas. The package of the folded frame is compact and can be transferred manually or moved to the next gripper on wheels or rollers without lifting means.

In FIG. 1 depicts in plan a volumetric rearranging formwork mounted on a technological gripper; in FIG. 2 - formwork during concreting of a building cell, cross section AA in FIG. 1; in FIG. 3 - framework of the formwork block in a perspective view; in FIG. 4 - insertion framework in a perspective view; in FIG. 5 - node I in FIG. 3; in FIG. 6 - node II in FIG. 3 and 4; in FIG. 7 - block, rolled up in a package; in FIG. 8 - insert, rolled into a package; in FIG. 9, 10 - docking of frames of blocks and inserts; in FIG. 11 is a diagram of the complete formwork.

The skeleton volumetric shuttering formwork includes a supporting skeleton in the form of a volumetric trellised structure 1 of a cell, which is composed of skeletons of blocks 2

or frames of inserts 3, or from a combination of frames of blocks 2 and inserts 3.

The frame of block 2 consists of two wall grilles 4 and 5 pivotally connected and an L-shaped ceiling lattice 6. Frame

insert 3 consists of a pivotally connected wall grid 4 and an L-shaped ceiling grid 6.

The grilles are assembled from struts 7 made of a bent profile. Hinged joints 8 are arranged on the inside of the chassis along the line connecting the grids 4, 5, C. The deck 9 is hung on the chassis. On the sides of the blocks and gates where the door and window openings are located, the deck 9 is hung with its edges adjoining the openings. Racks 10 of the frame1 at the places of installation of the openings are removable. To facilitate movement on

5 frames of blocks or inserts are fixed wheels or rollers 11.

Deck 9 can be made non-removable from cement-bonded or asbestos-cement or arbolite slabs, or decorative architectural concrete or fiberglass panels, which makes it possible to use the quality of non-traditional wall cheap local materials without surface finishing. The deck can also be made as a flat or decorative screen for applying pneumatic concrete in shotcrete technology.

An element 14 is installed along the connecting line of the vertical 12 and horizontal 13 parts of the L-shaped heating grate 6 for molding the cornice. The ceiling grating 6 is fixed relative to the wall grating 5 by a spacer screw 15. To increase the bearing capacity

5 frames of blocks and inserts use supporting supports 16, which are made in the form of a height-adjustable spatial structure installed on the underlying floors or floors of buildings and

0 structures, The connection of the gratings of the frames of the block and insert shown in FIG. 9 and 10, is carried out by connecting the end elements 17 of the blocks and inserts and transforming docking connections in the form of a strip 19 and a latch 20. The frames of the blocks and inserts are connected by jacks 21 for their alignment in the vertical and horizontal planes and a removable support 22 for securing the wheels or rollers 11.

The sizes of the blocks and inserts are unified and so selected. so that cells of different sizes could be concreted from the same blocks and inserts: only from blocks (cell B), from blocks and inserts (cell D), as a formwork (Fig. 1), external or separately standing walls can be used the same blocks and inserts (circuit B).

Before concreting, the blocks 2 and inserts 3 rolled up into bags are fed to the process gripper (Fig. 1). After that, in each cell, the frames of blocks and inserts are deployed and interconnected into spatial frames of the size of a cell. Blocks 2 and inserts 3 are also unfolded, interconnected and fixed along the bouquets B. The frames of the blocks and inserts are aligned in the vertical and horizontal planes with jacks 21. The ceiling grilles are supported by support legs 16, door and window openings are installed. elements for molding a cornice, after which a removable or fixed deck 9 is hung on the assembled spatial frame of the cell 9. The spatial frame 1 of the cell is attached to the floor or floor through embedded parts left during concreting of the underlying structures. The construction of a part of a building or structure on a process head is concreted.

After the concrete has gained formwork strength, the formwork is dismantled in the following sequence. The support legs 16 are removed, the spatial frames 1 of the cells are unfastened from the floor or overlap, the blocks 2 and inserts 3 are disconnected by releasing the latches 18 and the undocking of the end elements 17, The frames of the blocks 2 and inserts 3 are separated from the deck 9, lowered to the wheels or the rollers 11 and are folded into bags after lifting the jacks 21. Opening holes are removed and removed. The packages of blocks and inserts are manually removed through door or window openings. Package weight does not exceed 70 kg. Removable deck 9 is removed and removed

The block frame is folded into a bag as follows.

The spacer screw 15 is lowered, the jack 21 is lifted on the wall grate 5, which rotates to align with the grate 4, and then the ceiling L-shaped grate 6 is lowered relative to the hinge 8 until the removable support 22 is in contact with the wheel 11. The insert frame is folded

by turning the L-shaped lattice 6 to contact with the removable support 22 with the wheel 11.

The formwork variant with lightweight due to the rarefaction of the frame lattice with a removable deck 5 can be used as a screen for pneumatic concreting in shotcrete technology.

Danna skeleton volumetric-rearranged formwork provides significant flexibility of space-planning solutions for buildings and constructions.

This skeleton three-dimensional formwork allows saving ms tall, saving machine time of 5 lifting mechanisms, is easy to use, allows the use of a removable and non-removable deck, architectural concrete and fiber-reinforced concrete, frees up volumetric-planning decisions of buildings and structures, depending on the dependence on modular sizes of standardized formwork elements, providing flexibility of its application.
