Description

Double-triangular-support elevator shaft operating platform and construction method
Technical Field
The invention relates to the field of building construction, in particular to a double-triangular-support elevator shaft operating platform and a construction method.
Background
In high-rise and super high-rise construction processes, the elevator shaft position is due to the straight-up and straight-down through particularity, so that an elevator shaft operating platform is needed to facilitate the related construction of the elevator shaft. The elevator shaft is composed of a plurality of supports to form a supporting frame, and a plane plate is laid above the frame so as to facilitate standing operation of constructors and placement of tools and the like. Elevator shaft operation platform divide into multiple form: support formula elevartor shaft operating platform, landing leg are from convertible elevartor shaft operating platform, choose ear formula elevartor shaft operating platform, climb formula elevartor shaft operating platform etc. certainly. The support type elevator shaft operating platform is the type of the elevator shaft operating platform which is most widely applied, simpler in structure and better in economical efficiency.
The existing support type elevator shaft operating platform is designed into a triangular support, the triangular support is assembled and molded in an elevator shaft, and a tower crane is used for lifting or descending a welded suspension loop on the operating platform, so that the elevator shaft is moved. However, when the existing elevator shaft operating platform is used in practice, because the platform is subjected to dynamic load, the triangular support of the operating platform has higher stability requirement, if the stability is poor, an operator standing above the platform can feel the shaking of the support or the twisting of the support in the up-and-down moving process of the platform, and the elevator support has abnormal sound, so that the construction safety is influenced. However, if the diameter of the steel pipe of the support is increased to increase the stability of the support, the overall weight of the operation platform is too large, and the manufacturing cost of the platform and the lifting and moving cost of a tower crane are unfavorable.

The steel column and the bracket are made of I-shaped steel, the steel column and the bracket are used as main stress parts, and the I-shaped steel is high in rigidity and high in bending resistance, torsion resistance and pressure resistance.
The vertical rod and the diagonal rod are made of steel pipes, the steel pipes are assembled by fasteners, the installation and construction efficiency is improved, and the steel pipes are light in weight and have certain strength.
The first layer of cross beams and the inclined beams are made of T-shaped steel, and as a secondary stress part, the rigidity and the strength of the T-shaped steel are slightly lower than those of I-shaped steel, but the T-shaped steel can bear the stress sufficiently, and the weight of the T-shaped steel is not heavier than that of the I-shaped steel.
The construction method of the double-triangular-support elevator shaft operating platform comprises the following construction steps:
blanking each rod piece in a fixed length, cutting an end part to form a 45-degree oblique angle, and blanking the ribbed plate in a fixed size;
welding the steel column, the first layer of cross beam, the oblique beam, the bottom cross beam and the bracket into a triangular frame;
b, mounting the second-layer cross beam, the third-layer cross beam, the vertical rods, the inclined rods and the supporting beams in the triangular frame obtained in the step B by using fasteners;
placing the ribbed plate above the operating platform frame, penetrating the ribbed plate and the supporting beam below the supporting beam by using a U-shaped hanging ring, and fastening the ribbed plate and the supporting beam, thereby finishing the manufacturing and installation of the elevator shaft operating platform;
after the construction is finished, the elevator shaft operating platform is dismantled according to the reverse sequence of the steps A to D, and the elevator shaft operating platform is transferred to the next construction site for use
Compared with the prior art, the invention has the substantive characteristics and the progress that:
1. the operation platform integral structure is composed of a plurality of triangular stable structures, particularly a double-triangular supporting system is formed between the first layer of cross beams and the second layer of cross beams, the defects that a traditional elevator shaft operation platform frame is easy to deform and the middle of a platform plate is easy to dent are overcome, and the safety of the operation platform is improved.
2. The steel platform plate provided by the invention has the advantages that the rigidity and durability of the platform are greatly enhanced by combining the ribbed plate and the supporting beam; the platform is not easy to deform and dent.
3. The elevator shaft operating platform is simple and convenient in installation and manufacturing process, durable in structure, capable of being used for multiple times after being disassembled, and capable of saving construction material cost.
