Abstract

The utility model belongs to a beam hanging support type lifting/lowering scaffold used for building construction and decoration. The beam hanging support type lifting/lowering scaffold used for building construction and decoration is composed of a hanging steel beam 9, a hanging ring 13, a U-shaped bolt 11, a nut 10, a steel rib hanging cable 15, a hand pulling gourd 14, a draw rod 8 whose one end is provided with a movable sleeve 7, and an attached frame 1 which is built by a vertical rod 2, an abdomen rod 3, a slide rod 16, a scaffold plate 4, a connecting fastener, and a base 6. The beam hanging support type lifting/lowering scaffold used for building construction and decoration is characterized in that each attached frame is lifted by single the hanging steel beam 9, the steel rib hanging cable 15, and the hand pulling gourd 14 to realize the integral function of each attached frame. Therefore, the beam hanging support type lifting/lowering scaffold used for building construction and decoration not only has simple and convenient construction and expense saving, but also has safety and wide applicability.

Description

The utility model belongs to a kind of building operations and decoration scaffold.

In order to satisfy the needs of building operations and decoration construction, people will set up scaffold usually.What set up mostly is many vertical rods scaffold in the past, when this scaffold is used for highrise building, not only has high input, and sets up difficulty.In order to address these problems, there is the people once to invent attached wall Liftable type scaffold (China Patent No. 86203954) and unsettled attached wall rail mounted scaffold (China Patent No. 90205264).Though it is few that these two kinds of scaffolds drop into, expense is saved, and only limits the use of in the building of reinforced concrete wall structure but its shortcoming is it, is not suitable for the building of frame construction or other structure, and construction precision requires have deviation then to influence normal use slightly than higher.

The purpose of this utility model provides the outrigger formula lifting false work that a kind of easy to use, safe and reliable, expense is saved, applicability is wide.

The utility model mainly is provided with the drawknot bar 8 of quill 7 by cantilever steel girder 9, suspension ring 13, U-bolt 11, steel pipe card 12, nut 10, reinforcing bar hoist cable 15, Chain block 14, an end and with vertical rod 2, web member 3, slide bar 16, scaffold floor 4, connection fastener, be welded into or set up the attaching frame 1 that forms with the base 6 that steel pipe is barricaded as and form with shaped steel.

Below in conjunction with accompanying drawing detailed description is made in enforcement of the present utility model.

Fig. 1 is that attaching frame 1 described in the utility model is adhered to schematic diagram by cantilever steel girder 9, drawknot bar 8 and reinforcing bar hoist cable 15 with building.

Fig. 2 is the A-A view of the utility model Fig. 1.

Fig. 3 is the B-B view of the utility model Fig. 1.

Fig. 4 is that the utility model is along the horizontal overall plan view of a certain actual skin.

Fig. 5 is the C-C view of the utility model Fig. 1.

According to Fig. 1, Fig. 2, shown in Figure 3, with connection fastener many vertical rods 2, web member 3 and the base 6 that is welded into shaped steel or steel pipe is barricaded as are set up into attaching frame 1, the both sides of the base 6 of attaching frame 1 are welded two suspension hooks 5 respectively, and the medial surface both sides of attaching frame 1 are respectively equipped with a slide bar 16; Each attaching frame 1 needs 9 two of cantilever steel girders, and an end of cantilever steel girder 9 is anchored on the floor or by pre-embedded bolt and is anchored on the building with U-bolt 11, bolt card 12, nut 10 by the floor hole to be provided, and the other end then stretches out outside the building; Encorbelment and be welded with 13, two suspension ring 13 of two suspension ring on the cantilever steel girder 9 and be respectively applied for suspension reinforcing bar hoist cable 15 and Chain block 14 stretching out the outer end of building; The lower end of reinforcing bar hoist cable 15 is attached on the suspension ring 5 of base 6 of attaching frame 1, the upper end hangs on the suspension ring 13 that are welded in below the cantilever steel girder 9, the upper end of Chain block 14 hangs on another suspension ring 13 that are welded in cantilever steel girder 9 belows, and the reinforcing bar hoist cable 15 on another suspension ring 5 on lower end and the base 6 that is connected in attaching frame 1 is connected; The supporting of attaching frame 1 and lifting or decline realize by cantilever steel girder 9, reinforcing bar hoist cable 15 and Chain block 14; The quill 7 of drawknot bar 8 is set on the slide bar 16 of attaching frame 1, and this not only can make attaching frame 1 link to each other with building, and can keep the lifting of attaching frame 1 steady; When attaching frame 1 lifting, when the quill 7 of drawknot bar 8 is run into web member 2, can open quill, later again it is closed, when cantilever steel girder 9 is run into web member 2, can take web member 2 apart, later again it is loaded onto, behind attaching frame 1 lifting or decline first floor height, last layer or down the first floor face lay two cantilever steel girders 9 in addition, by upper strata or lower floor encorbelment steel-support and lifting or decline attaching frame 1, so go round and begin again then, can rise attaching frame 1 or descend on request, satisfy the requirement of structure construction and decoration construction scaffold.

According to shown in Figure 4, each attaching frame 1 is relatively independent, they are horizontal along skin, each attaching frame 1 is equipped with two cantilever steel girders 9, but when being in elevator shaft or other hoistway place, then need to use L shaped cantilever steel girder, see Fig. 5, L shaped cantilever steel girder 9 ' is anchored on the wall voluntarily by the L shaped shape of self.

The utility model is to use with the integral body that realizes each attaching frame 1 by cantilever steel girder 9, reinforcing bar hoist cable 15, Chain block 14 single lifting attaching frame 1, and therefore, it is easy construction not only, and expense is saved, and safe and reliable, and applicability is wide.

Claims

1, a kind of outrigger supporting type lifting false work, it mainly by with vertical rod 2, web member 3, link fastener, be welded into or set up form a plurality of with base 6, scaffold floor 4 that steel pipe is barricaded as and form along the horizontal rectangle attaching frame 1 of skin, drawknot bar 8, lifting means with shaped steel, it is characterized in that:

(1), respectively is provided with a slide bar 16 parallel on the both sides of the medial surface of each attaching frame 1 with vertical rod 2;
