Prefabricated reinforced concrete structural column for prefabricated buildings

Abstract

The invention aims at improving a prefabricated reinforced concrete column for prefabricated buildings and discloses a prefabricated reinforced concrete structural column for prefabricated buildings. The prefabricated reinforced concrete structural column is characterized in that a longitudinal part which belongs to a joint of a column body and a beam, is located in a reinforced concrete and is subjected to a force is still a reinforced concrete column body; the longitudinal part of the joint of the column body is not provided with a reinforce concrete later casting section and is a whole prefabricated column; outer thread is arranged on at least one part which belongs to an extended connection rebar and stretches out from a side surface of the column body; and at least one end of the longitudinal part of the column body is provided with a section steel joint and a connection rebar, wherein the section steel joint and the connection rebar stretch out from a end surface. Therefore, the prefabricated reinforced concrete column has the advantages that the prefabricated reinforced concrete column can utilize the existing reinforced concrete column design software to carry out graphing; through the connection of a column body and a beam rebar and the fast connection based on sleeve screw thread and chemical bonding, the vertical connection between column bodies is realized; through sleeve chemical slip-casting connection, fast connection between prefabricated building rebars is realized so that a prefabricated building assembling speed is greatly improved and a large amount of labor is saved; a joint of a column body and a beam is not provided with a reinforce concrete later casting section so that joint reinforce concrete strength can reach or exceed strength of a cast-in-situ reinforced concrete column structure; and through sleeve connection, the joint is reinforced thereby becoming a strong joint having seismic resistance.

Description

technical field

[0001] The present invention is a further improvement and perfection of the prefabricated reinforced concrete column for buildings in the applicant's prior patent application 201010120198.9, especially relates to a prefabricated reinforced concrete structural column for prefabricated buildings that can realize rapid installation and construction without changing the original building design . Background technique

[0002] The applicant first applied for the patent 201010120198.9 "Connection joints between prefabricated reinforced concrete columns and beams", and proposed a prefabricated reinforced concrete column with joints connected to beams. Axial steel pipes (stiff steel columns) are arranged inside, steel pipes and beams have steel joints radially protruding from the side of the column, the core and the connecting steel bars connecting the structural steel bars of the beams, and uncast concrete sections are left at the joints of the beams , after on-sit...

Examples

Embodiment 1

[0021] Embodiment 1: see Figure 1-4 , the prefabricated reinforced concrete structural column 2 for the prefabricated building of the present invention has a rectangular or square cross-section, and the longitudinal force in the concrete (including the connection node position with the beam) is made of the designed load-bearing steel bar 5 as the column reinforcement skeleton, and at the connection node with the beam Parts (take the cross connection beam as an example), there are joints 3 for the cross section of the column protruding from the side (internal connection with the column reinforcement), and at the position of the upper and lower structural steel bars of the connection beam, each has a column protruding from the side of the column with a diameter larger than that of the beam One level of structural steel bar, 4 connecting steel bars with external threads, the protruding thread length is 5cm, the thread reaches the side of the column, the height difference of cross...

Embodiment 2

[0024] Example 2: see Figure 5-16 , as in embodiment 1, the prefabricated reinforced concrete column 2 section shape can be L shape ( Figure 5 ), T-shaped ( Figure 6 ), cross ( Figure 7 ), a glyph ( Figure 8 ), at least one end of the longitudinal end face has protruding connecting steel joints 6 and protruding connecting column reinforcing bars 5; the connecting nodes of columns and beams have profiled steel joints 3 protruding from the side of the columns and connecting reinforcing bars 4 with threads on each side of the connection. The inner skeleton of the concrete column is still the column steel bar 5, and there is no post-cast section of concrete left. For column-to-column connections see Figure 5-8 , column to beam connection see Figure 9-16 ,in Figure 13-16 They are respectively connected cantilever structures.
