Abstract

The utility model relates to a suspended scaffold upright rod load-bearing base capable of moving for distance adjusting and used for fixing upright rods of a scaffold. The base is formed by a metal bottom plate and an upright short pipe welded on the bottom plate, and a pair of parallel edges of the metal bottom plate is respectively folded towards each other to form chutes matched with upper legs of an H-steel suspended beam. Row distance between two rows of the upright rods of the suspended scaffold can be conveniently adjusted by sliding the scaffold upright rod load-bearing base back and forth along the upper legs of the H-steel via the chutes on the bottom plate, thereby meeting row distance needs of double-row upright rods of scaffolds of different projects. The base has the advantages of having simple and small structure, being long-termed repeatedly usable, saving cost and enhancing working efficiency.

Description

The builder's jack vertical rod pressure-bearing base of removable roll adjustment

Technical field

The utility model relates to the builder's jack vertical rod pressure-bearing base of the pressure-bearing base, particularly a kind of removable roll adjustment that are used for fixing scaffold upright rod in the construction work.

Background technology

In the building engineering, the conventional fixed method of the inside and outside double steel pipe vertical rod of builder's jack all directly is bearing in i iron and encorbelments on the beam, and in scaffold building, use and demolishing process, vertical rod slippage takes place easily and produces hidden dangers such as support body inclination.Present improved method is: according to the array pitch of the double vertical rod of builder's jack, on encorbelmenting beam, welds I-shaped the short and small steel bar end of two high about 120mm, diameter phi 25～φ 28 in advance, then with inside and outside double vertical rod socket joint on steel bar end, prevent double steel pipe vertical rod generation slippage and produce the effect that support body tilts thereby play.Because the scaffold array pitch of different engineerings is inequality, therefore often need on encorbelmenting beam, weld in i iron short and small steel bar end again, to adapt to new array pitch.The welding of the repeated multiple times expense of not only taking a lot of work is expected, has also influenced carrying mechanical property and the number of turnover and the application life of i iron, is unfavorable for saving cost, improves work efficiency.

Summary of the invention

The purpose of this utility model provides a kind of builder's jack vertical rod pressure-bearing base of economic, practical removable roll adjustment, and it can regulate array pitch easily, to adapt to the needs of different engineerings, reaches the purpose that improves work efficiency.

The utility model is made up of a metal base plate and a vertical short tube that is welded on the metal base plate; The pair of parallel limit of said metal base plate is turned back and can be matched with the encorbelment last leg of beam of i iron to opposite side respectively, and the chute that can slide along last leg.

This scaffold upright rod pressure-bearing base can slide the array pitch of regulating the double vertical rod of builder's jack easily by chute front and back on leg on the i iron of base plate.This pressure-bearing understructure is simply small and exquisite, can the batch production typing produce in batches, but field machining is made again, once investment, prolonged and repeated turnover are used, can regulate the array pitch of inside and outside double steel pipe vertical rod after the on-the-spot assembling fast flexibly effectively, and stable, safety, reliable, saved existing scaffold needs again the expense of the taking a lot of work material work of the short and small steel bar end of a large amount of welding at every turn because of the adjustment of vertical rod array pitch, saved cost, improved work efficiency.

Description of drawings

Fig. 1 is the three-dimensional structure diagram of the utility model scaffold upright rod pressure-bearing base.

Fig. 2 is the encorbelment sectional drawing of beam annexation of scaffold upright rod pressure-bearing base and i iron.

Fig. 3 is the on-the-spot user mode schematic diagram of scaffold upright rod pressure-bearing base.

Among the figure, the vertical short tube of 1-, 2-metal base plate, 2-1-base plate chute, the 3-weld seam, row's steel pipe vertical rod in the 4-builder's jack, the 5-i iron beam of encorbelmenting, the encorbelment last leg of beam of 5-1-i iron, the 6-builder's jack effluxes the steel pipe vertical rod, encorbelment the fixedly short tube in the beam outside of 7-i iron.

The specific embodiment

Further specify example structure of the present utility model below in conjunction with accompanying drawing.

As Fig. 1, this builder's jack vertical rod pressure-bearing base is made up of a metal base plate 2 and the vertical zinc-plated short tube 1 that is welded on the base plate 2; A pair of chute 2-1 is turned back into to opposite side respectively in the pair of parallel limit of metal base plate 2.As Fig. 2, chute 2-1 and i iron encorbelment that the last leg 5-1 of beam 5 matches and can be on last leg 5-1 sliding transfer.Zinc-plated short tube 1 is weldingly fixed on the bearing bottom plate 2 by weld seam 3.

Metal base plate 2 adopts hot-roll forming or passes through the machining moulding by rectangular bar of steel plate.The length of the metal base plate 2 after the moulding should be more bigger than the last leg 5-1 width dimensions of i iron 5, be beneficial to form between the last leg of metal platen and i iron certain space, can on leg 5-1 on the i iron 5, slide front and back, realize regulating the function of the double vertical rod array pitch of builder's jack.

Fig. 3 is that the mounting means schematic diagram is set up at the scene of scaffold upright rod pressure-bearing base, among the figure, effluxes vertical rod 6 cover and is inserted on the short tube 7, and short tube 7 is the fixedly short tubes that directly are welded on the leg 5-1, so it is not removable to efflux vertical rod 6; Be used to overlap the pressure-bearing base of arranging vertical rod 4 in inserting and be assemblied in leg 5-1 by Fig. 2 mode, its base plate 2 can horizontally slip on last leg 5-1 by chute, regulate and efflux the distance of vertical rod 6, then inboard scaffold upright rod 4 covers are inserted on the vertical zinc-plated short tube 1, thereby make the inboard scaffold upright rod 4 and the array pitch of the scaffold upright rod 6 in the outside meet engine request.

Claims

1. the builder's jack vertical rod pressure-bearing base of removable roll adjustment is characterized in that being made up of a metal base plate and a vertical short tube that is welded on this metal base plate; The pair of parallel limit of said metal base plate is turned back and can be matched with the encorbelment last leg of beam of i iron to opposite side respectively, and chute that can the edge.
