Description

Technical Field

[0001] This utility model relates to a reverse-construction structural column based on a steel beam supporting a column, and relates to the field of building construction technology. Background Technology

[0002] With the deepening development of the construction industry, multi-functional and uniquely designed buildings are becoming increasingly common. When different floors of the same building have different functions, these functional requirements can be met through a "beam-supported column" system. This means that the structural columns cannot be directly continuous and run to the ground, but are connected to the lower vertical components via transfer beams. Some buildings, due to limited construction space or technical requirements, employ reverse construction methods. Ensuring effective connections between the structural columns, the lower transfer beams, and the upper structure, and ensuring that the connection points are easy to construct, becomes a crucial issue. Utility Model Content

[0003] This invention provides a reverse-construction structural column based on a steel beam supporting column to overcome the defects in the existing technology where the connection between the structural column and the lower-level transfer steel beam and the upper structure is not reliable.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a reverse-construction structural column based on a steel beam supporting a column, including a reverse-construction structural column. The reverse-construction structural column is provided with a template and a support body on its exterior. The upper part is connected to the upper structural beam slab, and the lower part is connected to the lower structural slab. The lower structural slab is connected to the lower steel beam. The upper flange of the lower steel beam is welded with a connecting steel plate. The reverse-construction structural column is provided with longitudinal steel bars inside the column body. One end of the longitudinal steel bar is connected to the reserved steel bar joint above it through a straight threaded sleeve, and the other end is welded to the connecting steel plate on both sides.

[0006] Furthermore, a flared opening is provided at the upper end of the template and support near the upper structural beams and slabs to serve as a concrete pouring port.

[0007] Furthermore, the connecting steel plate serves as an internal connecting component of the reverse-construction structural column, used for load transfer to the lower steel beam.

[0008] Furthermore, the number of connecting steel plates matches the longitudinal reinforcing bars in the column body of the reverse-construction column and are thin strips, using Q345B or Q355B steel, with a height ≥5d+h, a width of d+30mm, and a thickness of d, where d is the diameter of the longitudinal reinforcing bar of the reverse-construction column and h is the thickness of the lower structural slab.

[0009] The beneficial effects achieved by this utility model are as follows: the reverse-construction structural column acts as a "beam-supporting column" supported on the lower steel beam. By welding steel plates to the upper flange of the steel beam as connecting members for the internal reinforcement of the structural column, the load can be directly transferred to the lower steel beam, resulting in reasonable force transmission. The use of pre-reserved connecting steel plates replaces the use of pre-reserved rebar joints. The connecting steel plates are directly welded to the steel beam, which is more convenient than anchoring the rebar within the structural slab. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example 1

[0017] like Figure 1-3 As shown, a reverse-construction structural column based on a steel beam supporting a column includes a reverse-construction structural column 1. The reverse-construction structural column 1 is provided with a template and a support body 15 on its exterior. The upper part is connected to the upper structural beam 4, and the lower part is connected to the lower structural slab 3. The lower structural slab 3 is connected to the lower steel beam 2. The upper flange of the lower steel beam 2 is welded with a connecting steel plate 11. The reverse-construction structural column 1 is provided with longitudinal steel bars 13 inside the column. One end of the longitudinal steel bar 13 is connected to the reserved steel bar joint 12 above it through a straight threaded sleeve 14, and the other end is welded to the connecting steel plate 11 on both sides.

[0018] The upper end of the template and support 15 is provided with a flared opening near the upper structural beam 4 to serve as a concrete pouring port.

[0019] The connecting steel plate 11 serves as an internal connecting component of the reverse-construction column 1, used to transfer loads to the lower steel beam 2.

[0020] The number of connecting steel plates 11 matches the longitudinal steel bars 13 in the column body of the reverse structure column 1 and are thin strips. They are made of Q345B or Q355B steel, with a height ≥5d+h, a width of d+30mm, and a thickness of d, where d is the diameter of the longitudinal bar of the reverse structure column 1 and h is the thickness of the lower structural plate 3.

[0021] The construction sequence is as follows:

[0022] Step 1: Construct the lower steel beam 2 and the lower structural slab 3, wherein steel plate 11 is welded to the upper flange of the lower steel beam 2;

[0023] Step 2: Construct the upper structure beams and slabs 4. When constructing the upper structure beams and slabs 4, construct the column heads of the reverse structural columns 1, and at the same time reserve the column body steel bar joints 12. The steel bar joints 12 need to be staggered as required.

[0024] Step 3: Roughen the finished concrete surface and clean it thoroughly;

[0025] Step 4: Install the longitudinal reinforcing bars 13 of the reverse structural column 1. The longitudinal reinforcing bars 13 are connected to the upper reinforcing bar joint 12 by a straight threaded sleeve 14, and are connected to the lower connecting steel plate 11 by double-sided welding.

[0026] Step 5: Clean the roughened concrete surface again and set a mortar curb at the base of the column;

[0027] Step 6: Install the template and support system 15, and reserve a flared opening as a concrete pouring port.
