Description

(54) ЩИТОВАЯ ОПАЛУБКА(54) SHUTTLE FORMWORK

Изобретение относитс - к строительству и может быть испольг овано при возведении из бетонных и тому подобных смесей монолитных стен.The invention relates to the construction and can be used for the construction of monolithic walls from concrete and similar mixtures.

Известна опалубка дл возведени монолитных бетонных стен, включающа внутренний и наружный опалубочные щиты и устройства дл - их установки и фиксации в виде опорных площадок, штырей, ст жек и винтовых домкратов 1 .Known formwork for the construction of monolithic concrete walls, including internal and external formwork panels and devices for - their installation and fixation in the form of support sites, pins, jacks and screw jacks 1.

Недостатки известной впалубки - сложность конструкции и высока трудоемкость монтажных работ.The disadvantages of the known form - the complexity of the design and the complexity of the installation work.

Наиболее близким техническим решением к предлагаемому вл етс опалубка, содержаща наружные и внутренние шиты и устройство дл их установки и фиксации в виде консолей,, закрепленных на внутреннем щите и оборудованных захватами дл подвески наружного щита .The closest technical solution to the proposed is a formwork containing outer and inner shits and a device for their installation and fixation in the form of consoles fixed on the inner shield and equipped with hooks for hanging the outer shield.

Недостаток этой опалуки - невозможность изменени толщины бетонируемых стенКроме того, конструкци опалубки не позвол ет производить выверку положени наружного щита по высоте.The disadvantage of this form is the impossibility of changing the thickness of the concrete walls. Moreover, the formwork design does not allow for the alignment of the external shield height.

Цель изобретени - расширение технологических возможностей опалубки.The purpose of the invention is the expansion of the technological capabilities of the formwork.

Указанна цель достигаетс тем, что щитова опалубка дл возведени стен, включаюши внутренний и наружный опалубочные щиты и устройство дл подвески и фиксации наружного щита в виде консольной с опорами, консольна балка выполнена телескопической из двух частей с винтовыми домкратами на противоположных концах, причем один из домкратов соединен с внутренним щитом, а другой с наружным .This goal is achieved by the fact that shield formwork for erecting walls, including inner and outer shuttering boards and a device for hanging and fixing the outer shield in the form of a cantilever with supports, the cantilever beam is made of two parts telescopic with screw jacks at opposite ends, one of the jacks connected to the inner shield, and the other to the outer.

Claims

Shield formwork consists of an inner shield 1, an outer shield 2, screw struts 3, an upper service platform 4, a lower service platform 5 and a device for suspending and fixing the outer shield in the form of a telescopic cantilever beam 6, which is fastened with screws 7 on the inner shield 1 and c using the joint 8 is connected to the outer shield 2. At the end of the cantilever beam 6, on the side of the outer shield 2, a screw jack 9 is fixed, which rests on the stop 10 of the outer shield 2. On the inner shield 1 side, a home is also installed in the cantilever beam 6 Rat consisting of a rod 11, the stop 12, the slider 13 with a contoured slot 14 in which is located a finger 15. Moving the slider 13 limited by stop screw 16. The device operates as follows. Before installing the formwork into the working position, it is assembled, for which in the cantilever beam 6 on the joint 8 the outer shield 2 is illuminated. Then the outer shield z is hung with a crane. aa.cm ™ place the formwork on the grab without the SpoBaHHH, fix the inner shield 1 to the base and use the struts 3 to set it in the design position. The thickness of the wall to be removed is controlled by rotation of the rod 11. This moves the slider 13 and, using a finger 15 located in the shaped slot 14, changes the length of the telescopic cantilever: beams 6, shear boards 1 and 2, shear or push the positioning of the outer shield 2 in the vertical plane by rotating the rod 9 supported on the stop 10 of the outer shield. After alignment of the shields, they are fixed and a concrete mix is placed in the inter-panel space. After the concrete has set up the stripping strength, the concrete wall is dismantled. To do this, the rotation of the rod 11 opens the formwork panels from the concrete surface and remove them with a crane. Claims of ShchITT formwork for erecting concrete walls, including external and internal formwork panels and a device for hanging and. fixing the outside in the form of a cantilever beam with supports, characterized in that, in order to expand technological capabilities, the console beam is made telescopic of two, with jacks, on opposite ends, one of the jacks being connected to the inner shield and the other with the outer one.
