Problems solved by technology

Due to the relatively short development time of the prefabricated exterior wall system in my country, at this stage, the prefabricated precast concrete exterior wall system is mainly used in reinforced concrete structures; It cannot be applied to the field of prefabricated steel structure buildings

Embodiment 1

[0034] Please refer to the attached figure 1 To attach Figure 4 As shown, it is an embodiment 1 of a connection node between an upper load-bearing precast concrete exterior wall and a steel beam of the present invention, which is composed of a precast concrete exterior wall 100 , a steel beam 200 and a connection base 1 .

[0035] Wherein, the prefabricated concrete exterior wall 100 adopts single-layer wallboard or double-layer wallboard sandwiching thermal insulation cotton. The steel beam 200 is an I-shaped steel beam, a square tube beam or a box beam.

[0036] The connection base 1 connects the prefabricated concrete exterior wall 100 and the steel beam 200 , which includes a T-shaped plate 11 and a reinforcing rib 12 . The T-shaped plate 11 includes a horizontal portion 111 and a vertical portion 112 . The horizontal part 111 is connected to the upper flange of the steel beam 200 through the load-bearing anchor bolt 21, and the load-bearing anchor bolt 21 has a certai...

Embodiment 2

[0040] Please refer to the attached Figure 5 To attach Figure 8 As shown, it is the second embodiment of the connection node between the upper load-bearing precast concrete outer wall and the steel beam of the present invention. The difference between it and the first embodiment is that the horizontal part 111 is screwed with a load-bearing anchor bolt 21, The load-bearing anchor bolt 21 passes through a connecting channel 22 and abuts against the upper flange of the steel beam 200, and the connecting channel 22 is welded to the upper flange of the steel beam 200, thereby forming a rotatable support The seat has a certain horizontal and vertical displacement capacity, which prevents the wall from participating in the overall calculation of the structure. The similarities between the second embodiment and the first embodiment will not be repeated.

[0041] The connection nodes of the upper load-bearing prefabricated concrete outer wall and the steel beam of the present inve...

Abstract

The invention relates to a connection joint of an upper bearing prefabricated concrete external wall and a steel beam. The connection joint comprises the prefabricated concrete external wall, the steel beam and a connection base. The connection base 1 is connected with the prefabricated concrete external wall and the steel beam and comprises a T-shaped board and reinforcing ribs. The T-shaped board comprises a horizontal part and a vertical part. The horizontal part is connected with the steel beam. One side of the lower end of the vertical part is provided with an embedded bearing steel plate. The embedded bearing steel plate is embedded in the prefabricated concrete external wall. The upper end of the vertical part is connected with the prefabricated concrete external wall through positioning bolts and limiting bolts. The reinforcing ribs are welded to the T-shaped board. According to the connection joint, full-bolt splicing of the prefabricated concrete external wall and a steel structure can be completed on site; and through the horizontal movement type connection mechanism of the connection joint, the overall industrialization degree of steel structure buildings can be improved, and meanwhile, development of the steel structure building prefabrication and assembly technique in China is promoted.

Description

[0001] 【Technical field】 [0002] The invention relates to a connection structure between building components, in particular to a connection node between an upper load-bearing prefabricated concrete outer wall and a steel beam, and belongs to the technical field of construction engineering. [0003] 【Background technique】 [0004] In traditional buildings, most of the work needs to be completed on the construction site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction personnel have become barriers to the progress of the construction industry. Therefore, my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. [0005] The architectural prefabricated concrete exterior wall system is one of the signs of building industrialization. Compared with the cast-in-place concrete exterior wall system, the advantages of prefabricated concrete exterior walls ...
