Description

Technical Field

[0001] The invention relates to the technical field of connection between an ALC plate and a steel beam, in particular to an installation construction method for connection between an ALC plate and a steel beam. Background Art

[0002] With the acceleration of urbanization and the rapid development of the construction industry, my country's construction industry is facing increasing pressure on resources and the environment, extensive production methods, and unregulated markets, which restrict the sustainable development of the construction industry. Therefore, the construction industry needs to shift from high-speed development to high-quality development to achieve the goal of sustainable development. Green buildings and building industrialization are important development directions for the current high-quality development of the construction industry, which can effectively improve building quality and efficiency, reduce energy consumption and resource waste. ALC boards (steam lightweight concrete boards) have been widely used as a new type of building material in the process of building industrialization. At the same time, in order to meet the needs of building structures, the connection technology between steel beams and ALC boards is also constantly developing and improving.

[0003] In the connection between steel beams and ALC floor slabs, embedded connection technology is currently a commonly used method. This connection technology involves slotting or drilling holes in the steel beams, inserting the ALC slabs into them, and then fixing them by bolts or welding. However, slotting and drilling holes in the steel beams will cause deformation of the steel beams, affecting the stability of the beams; causing local stress concentration, affecting their service life. In addition, slotting and drilling holes will destroy the structural integrity of the steel beams and reduce their bearing capacity. In actual construction, the amount of ALC slabs laid is often huge, and it is difficult to use traditional embedded connection construction. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention proposes an installation and construction method for connecting an ALC plate with a steel beam.

[0005] The present invention provides an installation construction method for connecting an ALC plate with a steel beam, comprising the following steps: S1. Installation of steel beam: Install the steel beam in place; S2. Installation of full-length steel plate: a full-length steel plate is welded on the web of the steel beam. The full-length steel plate is set in a rectangular shape and is the same length as the steel beam. S3, installation of stiffening steel plates: weld several trapezoidal stiffening steel plates on the side of the steel beam connected with the ALC plate, the trapezoidal stiffening steel plates are arranged at the lower end of the full-length steel plate, and weld several rectangular stiffening steel plates on the side of the steel beam not connected with the ALC plate; S4. Laying of ALC plate: Lay the ALC plate on the upper end of the full-length steel plate along the length direction of the steel beam; S5. Post-processing of the board surface: adjusting the flatness and verticality of the board surface of the ALC board; using adhesive to process the gaps between the board units of the ALC board; using filler to process the gaps between the ALC board and the steel beam; bonding mesh cloth at the gaps between the two boards of the ALC board.

[0006] Preferably, the thickness of the full-length steel plate, the trapezoidal stiffening steel plate and the rectangular stiffening steel plate are all not less than 6 mm.

[0007] Preferably, in S2, the distance between the top surface of the full-length steel plate and the top surface of the steel beam is the thickness of the ALC plate.

[0008] Preferably, in S3, the welding intervals of the trapezoidal stiffening steel plates and the rectangular stiffening steel plates are both no greater than 600 mm.

[0009] Preferably, in S4, the distance between the side of the ALC plate and the flange of the steel beam is 10 mm, and the plate units of the ALC plate are closely attached to each other.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention proposes an installation construction method for connecting an ALC plate with a steel beam. By using a combination of a steel beam and an ALC plate, the need for grooving or drilling on the steel is avoided, thereby maintaining the integrity of the steel. Adding a stiffening steel plate to the web of the steel not only improves the load-bearing capacity of the structure, but also ensures the integrity of the ALC plate, avoiding structural damage to it caused by secondary processing. In addition, the method reduces the difficulty of construction and effectively improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0016] Example: Figure 1-Figure 3 As shown, an installation construction method for connecting an ALC plate with a steel beam comprises the following steps: S1. Installation of steel beams: Review the drawings to ensure that the design complies with the specifications and meets the requirements of structural safety and functional use. Conduct technical audits to ensure the feasibility and safety of the construction technology. Perform accurate measurement and layout work to determine the installation position and elevation of the steel beams. Review the measurement results to ensure the accuracy of the installation position. Use hoisting to install the I-shaped steel beam 1 in place.

[0017] S2. Installation of full-length steel plates: Before welding, clean up impurities such as oil, rust, and scale on the surfaces of the steel beam 1 and the full-length steel plate 2 to ensure welding quality. Use seamless welding to weld the full-length steel plate 3 on the web of the steel beam 1. The full-length steel plate 3 is set to be rectangular and has the same length as the steel beam 1. The side of the full-length steel plate 3 extends to the outside of the steel beam 1. The distance between the top surface of the full-length steel plate 3 and the top surface of the steel beam 1 is the thickness of the ALC plate. After welding is completed, the weld quality is checked.

[0018] S3. Installation of stiffening steel plates: weld several trapezoidal stiffening steel plates 4 on the side of the steel beam 1 connected with the ALC plate. The trapezoidal stiffening steel plates 4 are arranged at the lower end of the full-length steel plate 3. Weld several rectangular stiffening steel plates 5 on the side of the steel beam 1 without the ALC plate connection. The welding interval of the trapezoidal stiffening steel plates 4 and the rectangular stiffening steel plates 5 are both 600mm. Three-side seamless welding is adopted. Check the weld quality after welding is completed.

[0019] S4. ALC plate laying: ALC plate 2 is laid on the upper end of the full-length steel plate 3 along the length direction of the steel beam 1. The distance between the side of the ALC plate 2 and the flange of the steel beam 1 is 10 mm, and the plate units of the ALC plate 2 are closely attached to each other.

[0020] S5. Post-processing of the board surface: adjust the flatness and verticality of the board surface of ALC board 2; use adhesive to process the gap between the board units of ALC board 2; use filler to process the gap between ALC board 2 and steel beam 1; bond mesh cloth at the gap position between the two boards of ALC board 2.

[0021] Among them, the thickness of the full-length steel plate 3, the trapezoidal stiffening steel plate 4 and the rectangular stiffening steel plate 5 are all 6 mm.

[0022] This embodiment avoids the need to groove or punch holes in the steel beam 1 by using a combination of the steel beam 1 and the ALC plate 2, thereby maintaining the integrity of the steel beam 1. Adding a stiffening steel plate to the web of the steel beam 1 not only improves the load-bearing capacity of the structure, but also ensures the integrity of the ALC plate 2, avoiding structural damage to it caused by secondary processing. In addition, this method reduces the difficulty of construction and effectively improves construction efficiency.

Any equivalent schemes made using the contents of the present invention specification, directly or indirectly applied in other related technical fields, are also within the patent protection scope of the present invention.
