Description

Scaffold for construction site

Technical Field

The utility model relates to a building field, concretely relates to scaffold frame for building site.

Background

The scaffold refers to various supports erected on a construction site for solving vertical and horizontal transportation, and the scaffold for building is generally erected on the outer side of a building. The scaffold commonly used at present comprises a plurality of steel pipes and supporting leg fasteners, the steel pipes which are transversely arranged and vertically arranged in the scaffold are respectively called flat pipes and vertical pipes, the flat pipes and the vertical pipes are criss-cross to form a net-shaped structure, and the flat pipes and the vertical pipes are fixed together at the intersection of the flat pipes and the vertical pipes by the right-angle fasteners.

Because the steel pipe surface does not set up bearing structure, this kind of scaffold is in the use, when the flat tube atress, only relies on the static friction between right angle fastener and the standpipe to prevent the flat tube gliding. And the scaffold frame generally exposes in the external world for a long time, when using once more, if standpipe or right angle fastener take place the corrosion, when right angle fastener received pressure, the rust comes off with the standpipe easily, leads to right angle fastener to be difficult to the chucking standpipe.

Secondly, right angle buckle includes fixed connection and respectively with riser and two connecting portion of union coupling, even right angle buckle chucking is vertical and the plain tube, when the plain tube received decurrent pressure, the plain tube also only transmits power to riser department through right angle buckle's connecting portion, right angle buckle is under the condition of long-time use and corrosion, the unable emergence of avoiding of junction between two connecting portions damages, and the right angle buckle that uses on the building site is numerous in quantity, the workman is difficult to recognize right angle buckle one by one and whether damages, so cause the incident easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can carry out the scaffold frame for the building site that supports to the plain tube.

In order to achieve the above purpose, the technical scheme of the utility model is that: scaffold frame for building site, including plain tube, standpipe and right angle fastener, right angle fastener includes can dismantle plain tube connecting portion and the standpipe connecting portion of being connected with plain tube and standpipe respectively, and plain tube connecting portion are fixed with standpipe connecting portion, are fixed with the backup pad along axial clearance on the standpipe, and all backup pads all are located same straight line, and backup pad and plain tube connecting portion bottom offset.

The beneficial effects of the scheme are as follows:

1. when the scaffold is built, the flat pipe connecting portions are placed on the supporting plate, when the flat pipe receives downward pressure, the supporting plate supports the flat pipe in an auxiliary mode, the flat pipe is not supported by the fixed connecting portions between the flat pipe connecting portions and the vertical pipe connecting portions, even if the fixed connecting portions between the flat pipe connecting portions and the vertical pipe connecting portions are damaged, the flat pipe cannot be completely supported, and therefore the safety coefficient of the scaffold is higher.

2. When the flat pipe is pressed downwards, the supporting plate can bear a part of pressure, so that the effect of preventing the flat pipe from sliding downwards is achieved by only depending on the friction force between the vertical pipe connecting part and the vertical pipe, and the supporting effect on the flat pipe is better.

Furthermore, the top of the supporting plate is an inclined plane which is close to one end of the vertical pipe and lower than the other end of the vertical pipe.

The beneficial effect of this scheme does: when the plain tube received pressure, the inclined plane can provide the ascending holding power of slope for plain tube connecting portion to avoid the fixed connection department between plain tube connecting portion and the standpipe connecting portion to receive the pulling force of keeping away from the standpipe direction, further avoid the fixed connection between plain tube connecting portion and the standpipe connecting portion to be in the pulling force effect and damage down.

Further, the contained angle between inclined plane and the standpipe is 45 ~ 60.

The beneficial effect of this scheme does: when the contained angle is 45 ~ 60, under the same circumstances of width of backup pad, the space between backup pad and the standpipe has sufficient size to be used for installing flat union coupling portion, and need not increase the width of backup pad, reduces the materials of backup pad.

Furthermore, the bottom of the supporting plate is vertically fixed with a reinforcing plate, and one end of the reinforcing plate, which is close to the vertical pipe, is fixed on the vertical pipe.

The beneficial effect of this scheme does: the reinforcing plate can provide support for the backup pad, avoids the backup pad crooked.

Further, the reinforcing plate is located directly below the flat tube connecting portion.

The beneficial effect of this scheme does: the reinforcing plate in this scheme is just to the stress point of backup pad and flat union coupling portion, and is better to the support effect of reinforcing plate.

Furthermore, the end of the reinforcing plate far away from the vertical pipe is positioned on one side of the flat pipe connecting part far away from the vertical pipe.

The beneficial effect of this scheme does: the one end that the standpipe was kept away from to the reinforcing plate can be better supports the atress department of backup pad and flat union coupling portion, further improves the supporting effect.

Furthermore, the reinforcing plate is in a right trapezoid shape, and the bevel edge of the reinforcing plate is fixed with the supporting plate.

The beneficial effect of this scheme does: when the reinforcing plate is stressed, the right-angle edge positioned at the lower part of the reinforcing plate can avoid the reinforcing plate from bending deformation, so that the supporting effect of the reinforcing plate is improved.

Further, the bottom of the vertical pipe connecting part is lower than that of the flat pipe connecting part.

The beneficial effect of this scheme does: because the backup pad top is the inclined plane, standpipe connecting portion in this scheme also can contact with the backup pad top, thereby the backup pad can support standpipe connecting portion, improves the supporting effect.

Further, standpipe connecting portion bottom and flat pipe connecting portion bottom all are equipped with the support groove that can hold the backup pad.

The beneficial effect of this scheme does: the support groove and the support plate are matched to avoid torsion of the flat pipe connecting parts in the installation process, so that the flat pipe connecting parts are ensured to be positioned on the same straight line, and the flat pipe can pass through the flat pipe connecting parts to complete installation.

Further, the support plate and the vertical tube are integrally formed.

The beneficial effect of this scheme does: compared with welding, the connection of integrated into one piece is more firm, avoids the junction of backup pad and standpipe to damage.
