Description

Horizontal triangular beam

Technical Field

The utility model relates to the building field specifically is an used horizontal triangular beam of electric construction lift platform.

Background

At present, the electric construction lifting platform is applied to exterior wall decoration of curtain walls, paint, masonry and the like in the building industry, and can also be applied to other high-altitude operations, such as exterior wall renovation, curtain wall cleaning and the like. The use of the electric construction lifting platform has the following advantages that 1, the economic performance is good: no matter how high the building is, electric construction lift platform only need set up one (or two) stand and liftable operation platform along the building, can practice thrift a large amount of steel, according to (33 m height 30m length) 1000 square meters calculation, and fastener formula steel pipe scaffold frame needs about 22 tons of steel, and electric construction lift platform only needs 5 tons of steel, can practice thrift 80% steel in comparison, and higher more economical. 2, the safety performance is good: the electric construction lifting platform is a lifting machine driven by a gear and a rack, and a speed reducer of the electric construction lifting platform is a worm and gear speed reducer and has a self-locking function, so that the operation platform can be safely stopped at any height; the falling protector can be braked emergently when falling occurs, and major accidents such as falling of the operating platform and the like can be prevented; the electric system can automatically cut off the power when an accident happens, so that various accidents are avoided; meanwhile, the stand columns and the horizontal triangular beams of the electric construction lifting platform are of triangular structures with good stability, and the selected materials are all section bars with thick wall thickness, so that the bearing capacity of the electric construction lifting platform is improved. 3. The installation, use and dismantlement are convenient, efficient: when the electric construction lifting platform is installed, only one or two upright posts and a lifting operation platform are needed to be erected along a building, so that the electric construction lifting platform can be used for operation, and the situation that a plurality of layers of walkway plates are arranged along a circle around the building like an all-steel frame is not needed; when the lifting platform is used, the lifting of the electric construction lifting platform can be realized by using a remote controller or a button on a control box, the lifting platform is easier to operate than an all-steel frame, the number of machine positions controlled by the electric construction lifting platform is at most two, and the synchronism and the coordination are easier to guarantee than the simultaneous lifting of a plurality of machine positions of the all-steel frame; meanwhile, the lifting speed of the electric construction lifting platform is 6m/min, and quick lifting can be realized, so that the efficiency is improved, the electric construction lifting platform can start decoration without waiting for the completion of roof waterproofing, the time can be saved, and the efficiency is improved.

The platform part in the electric construction lifting platform is used for construction operation and material transportation, the platform consists of a plurality of horizontal triangular beams and steel springboards which are butted in pairs, and whether the horizontal triangular beams have enough strength, rigidity and stability can directly influence the operation and the safety of the electric construction lifting platform; whether the horizontal triangular beams are conveniently and quickly butted or not influences the speed and the efficiency of assembling the electric construction lifting platform.

The traditional horizontal triangular beam is formed by distributing three square tubes on three vertexes of an isosceles triangle to form a triangular prism, so that a main body structure of the horizontal triangular beam is formed, and when the triangular prism formed by the square tubes bears load, stress concentration is formed at the corners of a rectangular tube, so that the bearing capacity is reduced; the pipe is welded on the side around the triangular prism, and welded pipe both ends flatten earlier and handle, handle like this and can make to flatten a section parameter and diminish, are unfavorable for bearing the load.

Meanwhile, butt joints at two ends of the traditional horizontal triangular beam are formed by welding steel plates and bent steel plates on triangular prisms, and the butt joints are not easy to guarantee concentricity, so that the horizontal triangular beam is inconvenient and quick to butt; under the action of load, stress concentration is easily formed at the bending part of the bent steel plate, and the bent steel plate is not beneficial to bearing load; the board of bending also appears leaking welding, welds less, mistake welding phenomenon etc. easily in with horizontal triangular beam well square tube welding process, leaves the potential safety hazard easily, and the welding point is many, welds consuming time, can not reach the effect of saving time, saving expense.

SUMMERY OF THE UTILITY MODEL

Aiming at the above situation, in order to overcome the defects of the prior art, the utility model aims to provide a
