Description

The invention relates to the construction and can be used for the construction of monolithic buildings with monolithic walls and floors.

The purpose of the invention is to reduce labor costs and increase productivity.

Fig. 1 depicts lift-down formwork, a cross-section, the moment of concreting the floor and half the height of the wall; figure 2 - the same, the time of installation of the block formwork in the second half of the height of the floor; on fig.Z - the same, the moment of transfer of block formwork to the next floor; 4 is the same as the moment of transfer of the formwork for concreting a monolithic slab to the next floor; figure 5 is the same, a longitudinal section in figure 1; on figb - the same longitudinal section in figure 2; FIG. 7 is the same longitudinal section in FIG. 3; on Fig the same, a longitudinal section in figure 4.

Lifting-adjustable formwork contains block formwork 1 and formwork for monolithic overlap 2 and includes devices for lifting them in the form of a winch 3 and jack 4.

The block formwork 1 is equipped with a crosspiece 5 and guides 6. The formwork for concreting monolithic overlap 2 with lines 7 is provided with a U-shaped frame 8 containing vertical uprights 9 placed in the guides 6 of block formwork 1 and a transverse beam 10. Device for lifting in the form Winches 3 includes ropes 11 connected by one ends to the cross member 5 of the block formwork 1, thrown over the blocks 12 mounted on the transverse beam 10 of the U-shaped frame 8, and the counterweight 13 to the other ends. The counterweight 13 is connected to the winch 3 by means of a cable spare 14. The jack 4 is portable and is installed on the yoke 5 of the block formwork 1 and interacts with the transverse beam 10 of the U-shaped frame 8. The traverse 5 of the block formwork 1 is kinematically connected with the lever pair ( not shown) for its stripping.

Lifting-adjustable formwork contains supports 15 for installing block formwork 1 when transferring them to the following floors.

The formwork works as follows.

Prior to the installation of the climbing formwork, the first floor of the monolithic structure must be erected using

traditional methods without overlapping device. After that, the installation of the climbing formwork is made in the cells of the first floor of the erected structure with the help of crane mechanisms. Wherein

the formwork for concreting the monolithic slab 2 is brought to the design position in a known manner. Block formwork 1 also occupies a working position, resting on a formwork for concreting

monolithic overlap. In this position, the climbing formwork reinforces the structures and concretes. First, the construction of the ceiling is concreted, and then - the walls up to the height of block formwork 1. After the concrete has reached the structure of the walls, the formwork strength is dismantled. To do this, I work with a winch 3, using a rope stock 14 tons

down the counterweight 13, which in turn, through the ropes 11, thrown on the blocks 12 mounted on the crossbeam 10, pulls the traverse 5, which, due to the connection with the lever pairs (not shown), tears off the boards of block formwork 1 from concrete, and it is lifted to the second half of the wall being erected. At the same time, the block formwork 1 by means of the guides b rises along the vertical posts 9 of the U-shaped frame 8 and at a certain point its position is fixed on the vertical posts 9.

Rotate the lever pairs (not shown), the block formwork 1 is brought in

working position and concrete the second part of the wall. After the concrete has set the stripping strength in the manner described, the block form 1 is transferred to the following

floor and install it on pillars 15, located on the erected walls. After the concrete structure is overlapped, required formwork is dismantled to concrete monolithic overlap 2. For which, cable lines 14 of winch 3, already installed on traverse 5 of block formwork 1, are hooked to lines 7, and the formwork for concreting monolithic overlap to next floor. In this case, the stripping and raising of the formwork for concreting monolithic slab 2 is carried out in a known manner. When raising the formwork for concreting the monolithic overlap 2, the vertical uprights 9 of the U-shaped frame 8 move along the guides 6 of the block formwork 1 and are fixed on them when the required mark is reached.

The formwork for concreting monolithic slab 2 is brought to its working position in a known manner. After cleaning and lubrication of the formwork, the cycle is repeated. Fig. 8 shows a variant of raising the formwork for concreting a monolithic slab 2 to the next floor with a jack 4, which is installed between

traversing 5 block formwork 1 and a transverse beam 10 of the U-shaped frame 8 at the time of lifting.
