Embodiment 1

[0036] Please refer to the attached figure 1 to attach Figure 4 , and the attached Figure 8 As shown, the present invention is a connection node between a lower load-bearing precast concrete exterior wall and a steel beam, which consists of a precast concrete exterior wall 100, a steel beam 200, a lower load-bearing node 1 and an upper connection node 2.

[0037] 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.

[0038] The upper end of the lower bearing node 2 is pre-embedded in the precast concrete outer wall 100 , and the lower end is welded on the upper flange of the steel beam 200 . One end of the upper connection node 2 is pre-embedded in the precast concrete outer wall 100 , and the other end is anchored on the steel beam 200 .

[0039] The lower load-bearing node 1 includes a load-beari...

Embodiment 2

[0048] Please refer to the attached Figure 5 to attach Figure 7 , the present invention is a second embodiment of the lower load-bearing node 1 of the connection node between the lower load-bearing prefabricated concrete outer wall and the steel beam. The difference between it and the first embodiment is that one side of the vertical steel plate 111 is opened A vertical oblong hole 1111; a vertical adjustment plate 141 is respectively welded on both sides of the buckle steel plate 14, and each vertical adjustment plate 141 is screwed with a vertical high-strength bolt 4, and the vertical high-strength bolt 4 leans against the The top of vertical steel plate 111; Weld level adjustment plate 142 on each vertical adjustment plate 141, offer horizontal oblong hole 1421 on one of them horizontal adjustment plate 142, offer round hole 1422 on another level adjustment plate 142; Described vertical steel plate 111 is connected to the vertical adjustment plate 141 through a horizont...

Abstract

The invention relates to a connection joint of a lower bearing prefabricated concrete external wall and a steel beam. The connection joint comprises the prefabricated concrete external wall, the steel beam, a lower bearing joint and an upper connection joint body. The upper end of the lower bearing joint is embedded in the prefabricated concrete external wall, and the lower end of the lower bearing joint is welded to an upper flange of the steel beam. One end of the upper connection joint body is embedded in the prefabricated concrete external wall, and the other end of the upper connection joint body is anchored to the steel beam. According to the connection joint, the steel beam and a connection base are prefabricated in a factory, full-bolt splicing of the prefabricated concrete external wall and a steel structure is completed on site, the displacement, relative to a main structure, of the prefabricated concrete external wall can be completely released through the connection joint, and the situation that the wall participates in the overall structure calculation is avoided; and then joint seams of the wall face are subjected to waterproof treatment, fireproof treatment and the like. A large amount of welding work and wet work on site is reduced, the construction efficiency and quality of steel structure buildings are greatly improved, and safety and environment friendliness are achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to a connection structure between building components, in particular to a connection node between a lower 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 symbols of building industrialization. Compared with the cast-in-place concrete exterior wall system, the advantages of prefabricated concrete exterior walls...
