CS236808B1 - Modular vertical dumping shaft for building waste - Google Patents

Abstract

The vertical drop shaft of the three-element modular system solves the transport of rubble, dropping it in a vertical and oblique, but straight direction on the scaffolding, in the scaffolding, in the mirror of the staircase and the elevator shaft, by simple folding, while saving material, labor and energy consumption while maintaining a high variability of the solutions of use. Its use enables effective containerization of construction rubble. The shaft consists of panels and pullers, which are simply folded into the tubular scaffolding frame. It can be additionally, if necessary, reinforced with pullers in the necessary places. Its dimensions correspond to the dimensions of commonly used tubular scaffolding. The shaft can be used for the transport of material by gravity, but also as formwork for a monolithic skeleton.

Description

236808 3 4

The invention solves the vertical conveyance of the construction dry straight line, the shifting shaft construction system. The shaft is designed to be simple, fast and efficient to install and dismantle with high reliability and variability. In the prior art, the shovel chute has been carried out either by carpentry, directly on the construction site, or from a noisy, difficult-to-mount flange pipe, which often hurts even a prelaical finish by a building sufus.

These drawbacks are eliminated by the modular build-in dump shaft, which is housed in a supporting scaffolding structure, and is formed by panels of slabs provided with clamps and retracted pullers and a front panel, shorter than the remainder of the invention. the front panel has a lower fixed reflective wedge fixed at the bottom in the inner part, lying above the level of its lower edge, the wider portion of which lies downward. The pullers are loose or fastened externally on the upper edges of the panels and are positioned at both protruding ends with great notches, from which the forward end is open to the other end downwardly.

According to the invention, a new effect of the shaft is to save material for the construction of the shaft, labor on the construction site and thereby increase the productivity of the work. The dimensions of the shaft make it possible to place it in the underfloor surface of the elevator shaft, the stair mirror, which is always in a favorable location at the center of the building. The weight of the panels is low, which also allows manual paneling after construction. Variability of use is very high despite the low number of elements. It is also possible to leave any panel and replace it with a puller, for example in the use of a shaft in a slanted or horizontal position and other vertical structures. It can also be composed of two panels, in the form of the letter "V". It is simple to manufacture and can also be produced on site, from waste wood, with repeated use. The installation of the shaft allows for the con- struction of construction debris while saving. energy compared to the use of machines for vertical transport, saving labor in the operation of these machines. Workforce savings can also be achieved by reducing the handling of the shaft and the construction of the shaft. Rubble. it is also possible to drain on each floor of the scaffolding. The shaft can be placed on the tubular structure in five ways. It can also be mounted on the construction site outside the scaffolding, at the end of the scaffolding, in the middle of the scaffolding and in the scaffolding, while still maintaining the width of the scaffolding. It is most advantageous, in a 30 ° inclination, to use it in a sloping position, or to lay it on a scaffold. At all situational positions, the discharged part can be placed in a container and the alternative of the o-shaft also has a debris discharge closure so that the sut can be stored in the shaft body.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Fig. 1 is a view and Fig. 2 is a cross-sectional side view, Fig. 3 is a view and Fig. 4 is a front panel, Fig. 11 is a view of a stand, Fig. FIG. 6 shows a double tube mounting of the shaft, which is clamped by a 360 ° clutch with or without a 0 ° insert; Fig. 7 is a side elevational view of Fig. 6, Fig. 8 shows a one-way example of a shaft in an elevator shaft; Fig. 9 shows a third and fourth method of mounting a shaft with a hook connector and a tube d1. 30 cm, in Fig. 10 there is a fifth way for an extended crossbar.

The panels consist of plates 2, 3 and a stand 1 which has oppositely oriented notches on its ends for interconnecting the pullers 1. On the thatches there is a clamp 4 which has a precisely defined position and allows The shaft 2 additionally reinforces the bracing 5. The front panel 8 has a hole above the opening forming the wedge 6 which prevents the falling debris from falling out through the open hole. Usually, three side panels 7 and one front panel 8 are used, but can be combined freely. The shaft can be mounted on the scaffolding crossbeam 9 by the lower edge of the puller 1, the scaffolding stripper 10 by the notch in the puller 1. The scaffold has a stop 11, which must be raised according to the discharge opening of the shaft. The scaffolding floor for the passageway is formed by floor panels 12. The support deck for carrying the shaft, except for the cross members 9 and 10, further consists of metal sheets 17 rectified by the legs 19. The shaft is fixed by a scaffold provided with a double tube 14 fixed by a 360 ° scaffold A bottom plate 18 is sloping in the scaffolding under the shaft opening.

The shovel shaft can be used to transport the material by gravity, in various angles, on scaffolding positions, as well as standing alone in an elevator shaft, in a staircase mirror. It can also be used as a monolithic skeleton crate.
