Embodiment 1

[0026] combine Figure 1 to Figure 5 As shown, the connection node 1 between the steel column and the concrete beam in the reverse construction method provided by this embodiment includes a vertically arranged steel column 2 and a horizontally arranged concrete beam 3, and at the junction of the steel column 2 and the concrete beam 3 A steel bar 4 is welded on the steel column 2 below, and a shelving steel plate 5 is arranged on the steel bar 4 , and the longitudinal reinforcement (not shown) of the concrete beam 3 is fixed on the shelving steel plate 5 . The longitudinal reinforcing bars can be fixed by pads, or some vertical reinforcing bars can be set on the shelving steel plate 5, as the bracing frame of the longitudinal reinforcing bars, the longitudinal reinforcing bars are directly bound on the vertical reinforcing bars.

[0027] A preferred embodiment is to combine Figure 4 and Figure 5 As shown, the steel column 2 is circular, the steel strip 4 is circular, and th...

Embodiment 2

[0033] This embodiment provides a construction method for the connection node 1 of steel columns and concrete beams in the reverse construction method, which is combined below Figure 1 to Figure 5 , to further describe the construction method. The construction method includes:

[0034] According to the column bottom elevation of steel column 2 and the beam bottom elevation of concrete beam 3, calculate the position of concrete beam 3 and the connection node on steel column 2, and weld the steel plate at the position of the beam bottom elevation of concrete beam 3 at the connection node Strip 4; drive the steel column 2 vertically into the predetermined position; excavate the earth to the steel strip 4, hoop two semicircular annular steel plates 51 on the steel column 2, and weld the splicing ends of the two semicircular annular steel plates 51 to form The steel plate 5 is placed on hold, and the steel plate 5 is fixed on the steel strip 4; the steel bars of the concrete beam...

Abstract

The invention discloses a steel column and concrete beam connecting joint in inverse construction and a construction method, and belongs to the technical field of inverse construction. The connectingjoint comprises a vertically-arranged steel column and a horizontally-arranged concrete beam. Steel strips are welded under the connecting joint of the steel column and the concrete beam. A placing steel plate is arranged on the steel strips. Vertical steel bars of the concrete beam are fixed to the placing steel plate. The construction method comprises the following steps that the inserting surface between the steel column and the concrete beam is determined before steel column construction, the steel strip is welded in advance, when an earthwork is excavated to the steel strip, the placing steel plate is fixed, the steel bars of the concrete beam are bound so that the vertical steel bars can be fixed to the placing steel plate, and a mold is established and concrete is poured. The steelstrip and the placing steel plate are arranged at the inserting position between the steel column and the concrete beam, so that supporting points are provided for the vertical steel bars of the concrete beam, the vertical steel bars are fixed more firmly, component construction is safer, and the construction speed is higher.

Description

technical field [0001] The invention relates to a connection node between a steel column and a concrete beam in reverse construction and a construction method, and belongs to the technical field of reverse construction. Background technique [0002] In recent years, many cities in our country have experienced the process of rapid urban development, and land resources have become increasingly tense, making the development and utilization of urban underground space an inevitable trend. Utilization of underground space is a major issue for future urban development, and the reverse method is also a common method for underground space construction. In the upside-down method, steel columns are often used as vertical supports, concrete beams are used as horizontal supports, and horizontal beams are connected to steel columns. However, the construction process of the joint between the concrete beam and the steel column is cumbersome and the construction speed is slow, so there is a...
