Description

An assembled building steel structure

Technical Field

The utility model relates to the technical field of steel structure buildings, in particular to an assembled building steel structure.

Background Art

Compared with prefabricated concrete buildings, prefabricated steel structure buildings have the following advantages: there are no on-site cast-in-place nodes, the installation speed is faster, and the construction quality is easier to ensure. Steel structure is a ductile material with better seismic performance. Compared with concrete structure, steel structure has lighter weight and lower foundation cost. Steel structure is a recyclable material and is more environmentally friendly. Well-designed steel structure prefabricated buildings are more economical than prefabricated concrete buildings, with smaller beam and column cross-sections, which can obtain more usable area.

The existing steel structure beam-column joints are usually fixed by welding. Due to the uneven welding skills of construction workers, the strength of the joints is not high. When the steel structure beams and columns are subjected to large external forces, the joints are prone to de-welding and deformation.

To this end, we propose an assembled building steel structure.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Embodiment 1

Please refer to Figures 1-7. The utility model provides a technical solution: an assembled building steel structure, including a column 1 and a beam 2, the top and bottom inner ends of the beam 2 are symmetrically fixedly installed with sliding clamps 5, the top and bottom inner ends of the beam 2 are fixedly installed with a connecting plate 3 through the sliding clamps 5, the outer side of the connecting plate 3 is installed with a rotating installation plug 4, the connecting plate 3 is fixedly connected to the column 1 through the rotating installation plug 4, and the bolt 6 is threadedly connected to the outer side of the connecting plate 3;

The cross beam 2 is fixedly connected to the connecting plate 3 by means of the sliding clamp 5, and then the connecting plate 3 is fixed to the side of the column 1 by rotating the installation plug 4, that is, the column 1 and the cross beam 2 are fixedly connected by the connecting plate 3, which is easy to operate, has high fixing stability, improves construction efficiency, and has high reliability.

The sliding clamping member 5 includes a slider 51, which is fixedly mounted at the center of the inner end of the top and bottom of the cross beam 2. A slide groove 52 for the slider 51 to slide is provided at the bottom of the connecting plate 3. The slider 51 is slidably mounted in the slide groove 52. A plurality of clamping components 53 are evenly and equidistantly fixedly mounted on both sides of the slider 51.

The clamping assembly 53 includes a telescopic rod 532, a plurality of telescopic slots 531 are evenly and equidistantly provided on both sides of the slider 51, the telescopic rod 532 is fixedly installed on the inner side of the telescopic slot 531, a bevel clamping block 534 is fixedly installed on the telescopic end of the telescopic rod 532, a spring 1 533 is sleeved on the surface of the telescopic rod 532, the outer end of the spring 1 533 is fixedly welded on the inner side of the bevel clamping block 534, the inner end of the spring 1 533 is fixedly welded on the inner side of the telescopic slot 531, and a plurality of clamping slots 535 matching the plurality of bevel clamping blocks 534 are provided on both sides of the slot of the slide 52;

The connecting plate 3 is slidably installed in the slide groove 52 through the slider 51 and is slidably installed on the crossbeam 2. When the slider 51 is slidably installed in the slide groove 52, the inclined surface of the inclined surface block 534 is subjected to force. Through the decomposition of the force, it can be known that the inclined surface block 534 is subjected to a force in the direction of the telescopic groove 531. Then, the inclined surface block 534 compresses the spring 1 533 and the telescopic rod 532 under the action of the force, so that the inclined surface block 534 retracts into the telescopic groove 531 and does not block the slider 51 from sliding in the slide groove 52. When the slider 51 is completely slidably installed in the slide groove 52, a plurality of inclined surface blocks 534 correspond to a plurality of slots 535 one by one, and the inclined surface block 534 rebounds and is connected to the slot under the action of the spring 1 533. 535, and the connecting plate 3 and the beam 2 are fixed together and cannot be disassembled at this time. Because when you want to slide the connecting plate 3 out of the slide groove 52 again, the force-bearing surface of the inclined block 534 is parallel to the surface that exerts force on it, and the inclined block 534 is not subjected to the force in the direction of the telescopic groove 531 and cannot be retracted into the telescopic groove 531. The inclined block 534 will be connected in the slot 535 to prevent the slider 51 from sliding out of the slide groove 52, and the connecting plate 3 cannot be disassembled from the beam 2. Then the connecting plate 3 is fixed to the side of the column 1 by rotating the installation plug 4, that is, the column 1 and the beam 2 are fixedly connected through the connecting plate 3, which is easy to operate, has high fixing stability, improves construction efficiency, and has high reliability.

The rotating installation plug 4 includes an installation column 41, which is rotatably installed on the outside of the connecting plate 3. The inner end of the installation column 41 passes through the connecting plate 3 and extends to the outside thereof. A rotating knob 42 is fixedly installed on the outer end of the installation column 41.

A limit block 43 is fixedly installed at the center of the inner end of the top of the surface of the insertion column 41, and a mounting slot 44 adapted to the insertion column 41 on which the limit block 43 is installed is opened on the side of the column 1. A rotation slot 45 adapted to the limit block 43 is opened in the column 1, and the rotation slot 45 is connected to the mounting slot 44;

After the connecting plate 3 is fixedly installed on the beam 2, it is passed through the column 1 installed on the connecting plate 3, and the connecting plate 3 is installed on the side of the column 1 by inserting the installation column 41 into the installation slot 44. Then, the installation column 41 is rotated by turning the knob 42, and the installation column 41 drives the limit block 43 to rotate 90° in the rotation slot 45, and the rotation slot 45 is only for the limit block 43 to rotate 90°. At this time, the installation column 41 cannot be withdrawn from the installation slot 44 through the set limit block 43, and the connecting plate 3 is fixedly connected to the column 1. The column 1 and the beam 2 are fixedly connected through the connecting plate 3. In order to improve the stability of the device, the bolt 6 threadedly connected to the outside of the connecting plate 3 is threadedly installed on the side of the column 1, so that the column 1 and the connecting plate 3 are fixedly connected. The operation is simple, the fixing stability is high, the construction efficiency is improved, and the reliability is high.
