Abstract

The utility model discloses a combined scaffold for building engineering, which is an integral frame combined by a square matrix and a bottom frame, wherein, the square matrix is formed by splicing triangular steel frames. Each of the triangular steel frames is formed by fixedly connecting two horizontal steel elements with difficult lengths with two vertical steel pipes with difficult lengths. The steel pipes are respectively fixedly connected with bolt heads, and a base seat is formed by combining a steel element provided with a sleeve barrel with a spiral lifting device provided with a movable wheel. The utility model has the advantages of safe reliability, high stability, convenient assembly and disassembly, labor saving and time saving. The combined scaffold can be used for building engineering, and especially can be used for the inner decoration of advertisement propagandas, bridges, tunnels and halls, so that the advantages of flexibility and convenience can be shown.

Description

Assembly scaffold

The utility model belongs to the assembly scaffold that a kind of construction work is used.

At present, the construction work built generally adopts the scaffold of steel tube fastener formula.The scaffold of this steel tube fastener formula, built or folding frame are time-consuming.Especially when doing interior decorations such as advertising, bridge, tunnel, station, assembly hall, theater and need built, the frame hand frame of steel tube fastener formula more shows heaviness, the inferior position that operation is extremely inconvenient.Chinese patent discloses a kind of " construction work assembly scaffold " (application number 92242844.1).This utility model is provided with bearing between cross bar and scaffold floor, the both sides of scaffold floor have the locating hole that can insert U type card respectively, the side of vertical rod has bracing piece, there is the U-shaped clamp bottom of bracing piece, and the top of vertical rod inboard and bottom have loose pin and the fixed locating stud that can fix oblique bridging respectively.Although this utility model has easy advantage such as be suitable for, in constructions work,, just expose stable problem along with the increase of height.

The purpose of this utility model is to overcome above-mentioned weak point, and a kind of knockdown scaffold is provided.This assembly scaffold is the square square formation of many group triangle steelframes splicing and the general frame that base is united formation.

The utility model may reach by following measure:

Assembly scaffold is the square square formation of many group triangle steelframes splicing and the general frame that base is united formation.The triangle steelframe mainly is by horizontal two steel parts that are uneven in length and vertical two affixed forming of the steel pipe that is uneven in length.Steel pipe is affixed latch respectively, in long steel pipe fork down, fork is up in the short steel pipes.Fork exposes the size equity of steel pipe.

The base of assembly scaffold is to be combined by sleeved base steel part in two ends and spiral lift device.Wherein affixed latch, fork be up in the end sleeve.Fork equates with the internal diameter of steel pipe, sleeve.

Good effect and advantage that the utility model produces are:

1, assembly scaffold is the square square formation of many group triangle steelframes splicing and the general frame that base is united formation.During built, set base earlier, dock the triangle steel part then.On the insert edge of limit, quick, saving of work and time are increased work efficiency.Also extremely convenient during demolition.

2, be spliced into the square frame construction when the triangle steelframe, diagonal angle overlap joint horizontal brace pull bar, prevent the framework torsional deformation, strengthen mutual pulling force, safe and reliable, good stability.

3, knockdown scaffold not only is applied to building trade, but also can be applicable to the interior decoration of advertising, bridge tunnel, office building, auditoriums, hotels, these places more can demonstrate assembly scaffold flexibly, take the characteristics easily of rolling over.

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment: assembly scaffold is the general frame that the square square formation that is spliced into by triangle steelframe (1) and base (3) are united formation.

Triangle steelframe (1) is by horizontal two steel parts that are uneven in length and vertical two affixed forming of the steel pipe that is uneven in length.Steel pipe is affixed fork (2) (2 ') respectively.Long steel pipe fork (2) down, short steel pipes fork (2 ') is up.

The base of assembly scaffold (3) is respectively to have the base steel part (6) of sleeve (5) (5 ') and spiral lift device to combine by two ends.Affixed fork (2 ") in the sleeve of base steel part (6) one ends wherein.(2 ") up for fork.

(2 ") and steel pipe, sleeve (5 ') internal diameter are identical for fork (2) (2 ').

During built, set base (3) earlier, the screw rod that is about to spiral lift device is socketed in the sleeve (5) (5 ') of steel part.Then, splicing triangle steelframe (1), the fork of long steel pipe (2) enter fork in sleeve (5), the sleeve (5 ") (2 ") and enter short steel pipes, another secondary triangle steelframe (1) is inverted is docked and then, form the rectangle steelframe, be spliced to form the square square formation according to this.Utilize spiral lift device, rotate its handle and adjust the framework level, make four jiaos of square square formations in a plane.Draw intensity mutually, square diagonal angle overlap joint horizontal brace pull bar (4) for what strengthen triangle steelframe (1).

The set of many group square square formation frameworks and the associating of base (3) just constitute assembly scaffold.Convenient for activity, the base (3) of assembly scaffold can be equipped with movable wheel in low idle job.
