Embodiment 1

[0047] Example 1: A prefabricated reinforced concrete column

[0048] Such as Figure 1-4 , a prefabricated reinforced concrete column, the prefabricated reinforced concrete column includes two end plates 5 located at both ends of the cuboid soil column, several longitudinal bars 2 perpendicular to the end plates 5, and several closed stirrups surrounding the longitudinal bars 2 3. The concrete 1 is filled between the end plate 5, the longitudinal reinforcement 2 and the stirrup 3; the longitudinal reinforcement 2 passes through the third threaded hole 24 vertically through the two diaphragms 14 located in the concrete 1, and the upper The four corners of the diaphragm 14 and the four corners of the diaphragm 14 below are connected by four first angle steels 15 and the centers of the two diaphragms 14 are provided with holes, the diaphragm 14 and The diaphragm system 4 composed of the first angle steel 15 is surrounded by an outsourcing steel plate 7 composed of four vertical...

Embodiment 2

[0056] Example 2: A connection method between prefabricated reinforced concrete columns and steel beams

[0057] Specific steps are as follows:

[0058] First, the triangular reinforcement 8 is connected to the lower side of the vertical steel plate 20 through the second bolt hole 22 using the second bolt 23, the steel beam 9 is rested on the triangular reinforcement 8, and then the remaining triangular reinforcement 8 is passed through The second bolts 23 respectively connect the upper flange, lower flange and web of the steel beam 9 with the vertical steel plate 20 .

Embodiment 3

[0059] Example 3: A connection method between prefabricated reinforced concrete columns

[0060] Specific steps are as follows:

[0061] Connect the inter-column connector 6 with the horizontal steel plate 16 of the prefabricated reinforced concrete column end plate 5 by passing through the bolt holes on a layer of transverse triangular steel plate 13 by bolts, when the inter-column connector 6 connects the upper and lower soil column units , fill it with concrete so that it is flush with the cross-section of the soil column element.

Abstract

The invention discloses a prefabricated reinforced concrete column and a method for connecting prefabricated reinforced concrete columns or the prefabricated reinforced concrete columns with a girder,and belongs to the technical field of buildings and structural engineering. The designed prefabricated reinforced concrete column adopts an integration penetrating pouring way at a joint; strengthening connecting parts are used during column connection and gaps are filled with concrete; and during beam-column connection, an upper flange, a lower flange and a web of the girder are rigidly connected with the joint through strengthening parts, connection strength between the girder and joint is strengthened, and the designed novel prefabricated reinforced concrete column has better integrity than a general prefabricated reinforced concrete column. The prefabricated reinforced concrete column is completed in a factory, the quality is guaranteed, construction is convenient, and building wastegenerated in field construction can be reduced. The prefabricated reinforced concrete column and method are suitable for industrial production and conform to the trend of prefabricated buildings.

Description

technical field [0001] The invention relates to a connection method between a prefabricated reinforced concrete column and a soil column or with a steel beam, and belongs to the technical field of architecture and structural engineering. Background technique [0002] With the development of modern construction engineering, the application of prefabricated concrete frame structures is becoming more and more extensive. Some components of the prefabricated structure are processed and manufactured in the factory in advance, which makes the prefabricated building have the advantages of environmental protection and energy saving; and the construction period of the prefabricated prefabricated concrete frame structure is short. Assembling is performed with less wet work, reducing the time consumed for on-site fabrication, thereby shortening the construction period. Prefabricated concrete frame structures can also save turnover materials, and some parts of prefabricated components c...
