Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building partition board construction, in particular to a connection structure of a steel structure type steel beam and an ALC prefabricated wall board. Background Art

[0002] Steel structure buildings are widely used in housing, public and factory buildings due to their good earthquake resistance, flexible and variable space and environmental protection. ALC wall panels are widely used in the construction field due to their good thermal insulation, heat insulation, fireproof performance and energy saving characteristics. However, due to the different material properties, bonding problems, heat resistance and other factors at the connection between the steel and ALC wall panels, how to ensure the effective connection and fixation between the top of the ALC wall panel and the steel beam during the construction process and how to prevent the wall panel from collapsing during an earthquake during the later use process has become a restrictive factor restricting the use of ALC wall panels in the field of steel structure buildings.

[0003] Currently, the connection between steel beams and ALC prefabricated wall panels is usually made by drilling holes in the flange plate of the steel beam, fixing the connecting piece on the flange plate with bolts, bending the connecting piece to the wall of the ALC prefabricated wall panel, and then passing the long screw through a certain distance below the top of the ALC prefabricated wall panel. This connection method only fixes the position of one side of the ALC wall panel. In special circumstances such as earthquakes, the ALC prefabricated wall panel is prone to tipping over on the unfixed side. At the same time, drilling holes and fixing the flange plate of the steel beam is likely to weaken the flange plate on one side, resulting in a significant reduction in the force performance, which seriously affects the structural safety.

[0004] Therefore, it is necessary to provide a connection structure between a steel structure steel beam and an ALC prefabricated wall panel to solve the above technical problems. Utility Model Content

[0007] Preferably, the side wall of the ALC precast wall panel is provided with grouting holes communicating with the notch.

[0008] Preferably, sand aerated blocks are fixed on both inner walls of the steel section beam through viscous mortar.

[0009] Preferably, the outer wall of the sand aerated block is flush with the outer wall of the ALC precast wall panel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the drawings and embodiments.

[0019] Please refer to Figures 1 to 3, A connecting structure between a steel structural section steel beam and an ALC precast wall panel, including components such as an ALC precast wall panel 1, a U-shaped connecting piece 2, masonry mortar 3, a section steel beam 4, an L-shaped connecting and fixing piece 6, and an alkali-resistant fiber mesh cloth 7. Among them, a notch a is specially designed at the top of the ALC precast wall panel 1, and the U-shaped connecting piece 2 is carefully embedded in this notch a, and the U-shaped connecting piece 2 and the ALC precast wall panel 1 are firmly fixed by injecting grouting liquid 5 to ensure the stability and firmness of the connection.

[0020] Furthermore, plane connecting parts b symmetrically extend from both ends of the U-shaped connecting piece 2. These plane connecting parts b are cleverly arranged outside the ALC precast wall panel 1 and are welded and fixed to the bottom of the section steel beam 4, thus realizing a firm connection between the ALC precast wall panel 1 and the section steel beam 4. At the same time, in order to enhance the integrity and aesthetics of the wall, the gap between the top of the ALC precast wall panel 1 and the section steel beam 4 is carefully filled with masonry mortar 3, making the whole structure more compact and tidy.

[0021] In order to facilitate the injection of grouting liquid 5 into the notch a, a grouting hole c communicating with the notch a is also specially provided on the side wall of the ALC precast wall panel 1. This design greatly improves the convenience and efficiency of construction.

[0022] On the inner walls on both sides of the section steel beam 4, sand aerated blocks 9 are firmly fixed by adhesive mortar. The outer walls of these sand aerated blocks 9 are flush with the outer wall of the ALC precast wall panel 1, further enhancing the integrity and stability of the wall.

[0023] In order to prevent plastering cracks from occurring during the later plastering construction, an alkali-resistant fiber mesh cloth 7 is specially adhered at the connection joint between the outer wall of the sand aerated block 9 and the ALC precast wall panel 1. This measure effectively improves the durability and crack resistance of the wall.

[0024] Finally, for the convenience of connection and fixation, L-shaped connecting and fixing pieces 6 are firmly connected to both sides of the bottom of the ALC precast wall panel 1 by screws 8. This design not only enhances the stability of the structure but also provides convenience for subsequent construction and maintenance.

[0025] Construction steps:

[0026] 1. On the floor structural slab, the wall axis position is set out according to the wall axis position relationship in the building construction drawings;

[0027] 2. Install the L-shaped connecting and fixing piece 6 at the single-side position of the wall axis according to the set-out building wall axis, thereby playing a preliminary fixing effect on the subsequent installation of the ALC precast wall panel 1;

[0028] 3. According to the positional relationship of the top notch a of the ALC precast wall panel 1, weld the U-shaped connector 2 at the corresponding position at the bottom of the profiled steel beam 4. The planar connecting part b of the U-shaped connector 2 is welded and fixed to the bottom of the profiled steel beam 4 by double-sided welding; when the wall thickness is less than or equal to 150 mm, the U-shaped connector 2 is welded along the longitudinal direction of the profiled steel beam 4, and when the wall thickness is greater than 150 mm, the U-shaped connector 2 is welded perpendicular to the longitudinal direction of the profiled steel beam 4.

[0029] 4. The ALC precast wall panel 1 is installed using special masonry mortar according to the wall axis that has been marked according to the axis position. The root is fixed to the L-shaped connecting and fixing piece 6 with screws 8. The top notch a of the ALC precast wall panel 1 corresponds to the position of the U-shaped connector 2, and the verticality of the precast wall panel is corrected. After the verticality correction of the precast wall panel is completed, install the L-shaped connecting and fixing piece 6 on the other side of the wall root and fix it with bolts 8;

[0030] 5. The end of the grouting machine hose is slowly grouted towards the grouting hole c at the top of the ALC precast wall panel 1 until the notch a at the top of the ALC precast wall panel 1 is filled with slurry;

[0031] 6. When the strength of the grouting liquid meets the requirements, fill the top gap of the ALC precast wall panel 1 with masonry mortar 3;

[0032] 7. The sand aerated concrete block 9 is fixed by smearing viscous mortar on the inner wall of the profiled steel beam 4. The alkali-resistant fiber mesh cloth 7 is arranged at the joint between the sand aerated concrete block 9 and the ALC precast wall panel 1 to prevent cracking during the later plastering construction.
