Description

Prefabricated constructional column that joint strength is high and be convenient for installation

Technical Field

The invention relates to the technical field of construction tools, in particular to a prefabricated constructional column which is high in connection strength and convenient to install.

Background

The recent development of industry and the enlargement of cities require the construction of large batches of factories, warehouses, houses, railway buildings, office buildings, commercial service buildings, etc. The monarch palace, the altar temple and the tomb which occupy prominent positions in the construction history for a long time are withdrawn from secondary positions, and the construction with the main aspects of productivity and practicability is increasingly important. New functional requirements are put forward for novel buildings. Some require large span. The building form changes rapidly, and the traditional setting French system can not meet the requirements after moving, and concrete columns are arranged at the specified positions of the wall body of a masonry house according to the structure reinforcement and the construction sequence of building the wall first and then pouring the concrete columns, which are generally called concrete constructional columns and are called constructional columns for short. Constructional columns are important concrete elements in brick and concrete structural buildings. In order to improve the seismic performance of the masonry structure of the multi-storey building, the specification requires that a reinforced concrete column is arranged at a proper position in the masonry of the building and is connected with a ring beam to jointly enhance the stability of the building, and the reinforced concrete column is generally called a constructional column. The constructional column is mainly used for resisting transverse loads such as shearing force, earthquake and the like instead of bearing vertical loads. From the construction perspective, the constructional column is integrally cast with the ring beam ground beam and the foundation beam. The brick wall body is connected with a horizontal tie bar in the structural engineering. The first change in the building industry was to use iron for building construction if the structural columns were to be connected to distribution ribs at the building, at intermediate locations of the building. Firstly, iron is used as an inner column of a house, then a beam and a roof truss are made, and iron is also used for making a dome. In the late phase of the nineteenth century, the steel yield is greatly increased, and steel with more excellent performance replaces iron materials. Meanwhile, cement is gradually used for building construction.

The present prefabricated constructional column is mostly the not telescopic constructional column of integral type, and the outside of constructional column does not mostly have the strengthening rib that is used for the increase of strength for the intensity of constructional column reduces, and the constructional column that has now moreover is not convenient for install, makes the construction workman can not be quick install the constructional column outside the wall body that needs the enhancement, the workman's that reduces work efficiency.
