Description

Building scaffold, construction guardrail mounting

Technical Field

The utility model relates to a scaffold for building, construction guardrail mounting belongs to the building engineering field, especially relates to an old building reforms transform scaffold for building and construction floor face limit safety protection railing temporary fixing spare.

Background

With the rapid development of urban construction, a plurality of old buildings can not be dismantled and rebuilt due to short service life or other reasons, and only the outer walls of the old buildings are renovated and reformed, so that new effects of the old buildings are achieved. When the old building is transformed, the steel pipe external scaffold is normally used in the building, only the external wall is transformed, and the steel pipe external scaffold used in the common building construction must be rigidly connected with the building structure into a whole, so that the safety accidents of collapse and overturn of the scaffold body are avoided. Because the steel pipe can not be installed through the wall for drawknot, the scaffold and the building structure are difficult to drawknot, and great potential safety hazard is caused. The danger that the limit portion position exists the high altitude and falls is faced in the construction floor, often needs the installation to prevent temporarily that the railing from preventing the personnel from falling. The existing technical method is that after an anchoring steel plate is fixed on an outer wall concrete member by using an expansion bolt, a wall connecting tie steel pipe is welded, or a switching steel pipe is welded on the wall anchoring steel plate, the switching steel pipe needs to be perforated, and when a scaffold is dismantled after the wall connecting tie steel pipe is used, the steel pipe at the welding position is cut off by gas cutting. In the prior art, the workload of field welding and dismantling and cutting after use is large, high-altitude electric welding is carried out on a scaffold, the cutting operation efficiency is low, the welding quality is difficult to ensure, and the safety risk is overlarge; but also the steel pipe deckle edge that remains that causes when cutting because of the gas cutting need polish, but steel sheet side reuse, the cost is artifical. The work load of punching the round steel pipe adaptor is large, and the strength of the steel pipe can be influenced. And the other one is, for example, the Chinese patent CN208294057U, the right-angle steel tube of the technology has high processing precision requirement, the manufacturing efficiency is slightly low, the position of the rear fixed steel plate can not be properly adjusted, the material consumption of the steel tube of the welded steel plate section is larger than that of the angle steel of the invention, and the cost is slightly higher.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned not enough, the utility model provides a construction scaffolding, construction guardrail mounting adopts prefabricated finished product steel member, and steel member welding quality can be guaranteed in the batch production processing preparation, and on-the-spot expansion bolts is fixed the back and directly links firmly the wall steel pipe with the scaffold fastener tightly, need not carry out high altitude weldment work on the scaffold, and the efficiency of construction is high, and the potential safety hazard that has significantly reduced.

The utility model adopts the technical proposal that: a building scaffold and construction guardrail fixing piece comprises a first connecting piece, a second connecting piece and connecting steel pipes, wherein four oval bolt holes are uniformly formed in four corners of the first connecting piece, one end of the second connecting piece is vertically welded in the middle of the first connecting piece, the other end of the second connecting piece is provided with the connecting steel pipes, and the connecting steel pipes are connected with a horizontal steel pipe tie piece of a scaffold; the first connecting piece is fixed on a concrete structure of a building through a bolt.

Furthermore, the first connecting piece is a square steel plate with the thickness of 150 multiplied by 150mm, the second connecting piece is angle steel with the thickness of 50 multiplied by 5mm, and the second connecting piece is welded at the central position of the first connecting piece.

The oval bolt hole is two-way setting, two promptly for the level setting, two are vertical setting.

The connecting steel pipe is a steel pipe with the diameter of 48 mm multiplied by 3.5mm and the length of 200 mm; the bottom of the connecting steel pipe is welded with the second connecting piece into a whole.

The bolts are four lengthened expansion bolts with the diameter of 12 mm.

The utility model discloses be used in building engineering construction floor face during the limit operation face, directly beat expansion bolts fixed can install the steel pipe railing fast, need not set up the bracing steel pipe, the construction is swift, reduce the material use amount, still can practice thrift the space that the bracing steel pipe occupy. The steel pipe fasteners are fixed on the fixing piece provided by the utility model, and the rigid connection ensures that the scaffold is firmly tied on the concrete structure of the building to form a stable whole, thereby ensuring the safe operation of constructors; after the steel member is used, the finished steel member is loosened and removed without gas cutting, so that the steel member is fast, efficient and safe, and can be recycled.

The utility model provides a building scaffold, construction guardrail mounting, the beneficial effect who brings:

(1) the utility model discloses cancelled and welded, cut the working procedure on the scaffold frame, the batch production preparation is semi-manufactured goods, punches during the use on-the-spot concrete structure and can install, removes finished steel member with the back, but reuse, the efficiency of construction is high, with low costs, and the potential safety hazard that has just significantly reduced.

(2) The high-rise or multi-storey floor construction layer of building engineering faces the limit department and adopts to beat rearmounted anchor slab and weld steel pipe railing or sets up railing and diagonal brace with the fastener and keeps stable, takes a lot of work and wastes material.

(3) Adopt the utility model discloses, the installation or demolish swiftly, firmly stable during the use, but mounting demolishs back reuse.

The present invention will be further explained with reference to the drawings and examples.
