Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building structures, in particular to an assembled fire wall structure. Background Art

[0002] In my country, steel structure workshops are widely used in the construction industry due to their significant advantages such as stable structure, high strength, light weight and short construction period. Their beautiful and simple appearance, fire prevention and anti-seepage, ventilation and cooling make them suitable for different industrial needs. At the same time, steel structure workshops are green, environmentally friendly and reusable, which conforms to the concept of sustainable development. The main function of the firewall is to separate the fire partitions and prevent the fire from spreading inside the workshop, thereby protecting the safety of personnel and property. In a steel structure workshop, once a fire occurs, the firewall can effectively isolate the fire and prevent the further spread of the fire, which is crucial to ensure the safety of industrial production and the safety of life and property of employees. At present, most traditional firewalls adopt the method of brick firewalls.

[0003] However, traditional brick firewalls have the following shortcomings: First, since the floor height of steel structure factories is generally high, mostly exceeding 10 meters, the traditional brick firewall needs to increase its thickness accordingly to ensure its stability, which not only poses a safety hazard but also increases the construction cost; secondly, steel structure factories are load-sensitive structures. Due to the large deadweight of the masonry blocks, they will absorb too much seismic force and transmit it to the steel structure, increasing safety hazards; thirdly, the connection process between the steel beams and columns of the steel structure factory and the brick firewall is complicated, which not only increases the construction difficulty and construction period, but also may affect the fire resistance of the firewall; finally, the heavy design of the brick firewall also affects the aesthetics and overall coordination of the steel structure factory.

[0040] Combine the following Figures 1 to 5 , the assembled firewall structure provided in the embodiment of the present application is described in detail through specific examples.

The assembled fire wall structure 100 provided in one embodiment of the utility model includes a transverse main keel 10, a vertical main keel 20, a secondary keel 30, a fireproof board 40, a fireproof cotton 50, a first connecting component 60 and a second connecting component 70. The transverse main keel 10 and the vertical main keel 20 are connected to each other to form a steel keel rack; the secondary keel 30 is vertically and evenly distributed on the transverse main keel 10 to form a plane system; the fireproof board 40 is arranged on both side surfaces of the plane system; the fireproof cotton 50 is arranged between the fireproof boards 40 on both sides; the first connecting component 60 is arranged at the connection between the transverse main keel 10 and the vertical main keel 20 to connect the transverse main keel 10 and the vertical main keel 20 to each other; the second connecting component 70 is arranged at the connection between the transverse main keel 10 and the secondary keel 30 to connect the transverse main keel 10 and the secondary keel 30 to each other.

[0042] The steel keel rack formed by the interconnection of the transverse main keel 10 and the vertical main keel 20 and the vertical uniform distribution of the secondary keel 30 make the entire firewall structure highly stable and can effectively withstand various external forces. Moreover, the assembly of the transverse main keel 10 and the vertical main keel 20 makes the firewall structure 100 thinner and lighter. The fireproof board 40 is arranged on the two side surfaces of the plane system, and the fireproof cotton 50 is filled between the two side fireproof boards 40, which can improve the fireproof performance of the firewall and effectively prevent the spread of fire.

[0043] Among them, the horizontal main keel, vertical main keel, first connection assembly and second connection assembly can all be accurately manufactured in advance at the steel structure manufacturer to ensure reliable quality. On site, they can be assembled directly by bolts without the need for on-site construction welding, which not only greatly improves construction efficiency, but also ensures assembly accuracy, and has significant time advantages compared to traditional bricklaying methods.

[0044] In some embodiments, the first connecting assembly 60 includes a grooved connecting plate 61 and fixing bolts 62; the grooved connecting plate 61 is disposed on the vertical main purlin 20 and fixed to the vertical main purlin 20 by fixing bolts 62; the grooved connecting plate 61 and the horizontal main purlin 10 are welded to each other.

[0045] The grooved connecting plate 61 is fixed to the vertical main purlin 20 by means of fixing bolts 62, providing a firm mechanical connection, ensuring a tight connection between the transverse main purlin 10 and the vertical main purlin 20, and further enhancing the stability of the overall structure.

[0046] The grooved connecting plate 61 and the transverse main keel 10 are welded to each other, so that the grooved connecting plate 61 and the transverse main keel 10 are set as an integrated structure. When the transverse main keel 10 and the vertical main keel 20 need to be connected to each other, since the grooved connecting plate 61 and the transverse main keel 10 are welded to each other, the grooved connecting plate 61 can be directly installed on the vertical main keel 20, and the assembly between the transverse main keel 10 and the vertical main keel 20 can be completed. Through such a setting, the connection between the transverse main keel 10 and the vertical main keel 20 can be made simpler.

[0047] Specifically, the grooved connecting plate 61 and the transverse main purlin 10 can be welded in the factory and then directly assembled and installed on site. With such an arrangement, when the transverse main purlin 10 and the vertical main purlin 20 need to be installed on site, the transverse main purlin 10 and the vertical main purlin 20 can be directly connected through the grooved connecting plate 61, so that the transverse main purlin 10 welded with the grooved connecting plate 61 can be connected with the vertical main purlin 20. In this case, the grooved connecting plate 61 does not need to be welded on site, which can greatly save assembly time.

[0048] In some embodiments, the groove-shaped connecting plate 61 is provided with a slot 611 , the slot 611 is arranged toward the vertical main purlin 20 , and the width of the slot 611 is the same as the width of the vertical main purlin 20 .

[0049] The grooved connecting plate 61 is provided with a groove 611 of the same width as the vertical main purlin 20, which can ensure the accurate matching of the grooved connecting plate 61 and the vertical main purlin 20, and help improve the overall installation accuracy and connection stability. By setting the groove 611 of the grooved connecting plate 61 to be the same width as the vertical main purlin 20, the connection is made tighter, preventing the vertical main purlin 20 from loosening, thereby improving the durability of the connection part. This helps to improve the overall structural performance and fire isolation effect of the firewall.

[0050] Specifically, when the grooved connecting plate 61 and the vertical main keel 20 need to be installed, the vertical main keel 20 can be inserted into the groove 611 so that the vertical main keel 20 can be accommodated in the grooved connecting plate 61. Through such a configuration, the installation steps are simplified and the installation efficiency is improved.

[0051] In some embodiments, a first reserved hole 612 is opened on the groove-shaped connecting plate 61, and a second reserved hole 21 is opened on the vertical main keel 20; the position of the first reserved hole 612 corresponds to the position of the second reserved hole 21; the fixing bolt 62 is sequentially passed through the first reserved hole 612 and the second reserved hole 21 to fix the groove-shaped connecting plate 61 and the vertical main keel 20.

[0052] The method of fixing the bolts 62 through the reserved holes simplifies the on-site installation process, eliminates the need for complicated welding or other connection methods, and improves installation efficiency. If the structure needs to be adjusted or corrected during the installation process, the design of the reserved holes makes the adjustment more convenient because the bolts can be loosened or adjusted. In addition, the accurate position and size of the reserved holes help reduce the stress concentration of the bolts, thereby improving the durability of the connection part.

[0053] Specifically, when the vertical main keel 20 is inserted into the notch 611 on the groove-shaped connecting plate 61, the positions of the first reserved hole 612 and the second reserved hole 21 correspond to each other, so that the fixing bolt 62 can be inserted into the first reserved hole 612 and the second reserved hole 21. With such a setting, the vertical main keel 20 and the groove-shaped connecting plate 61 can be quickly connected.

[0054] The grooved connecting plate 61 is a prefabricated grooved steel plate, the groove of which is clamped on the vertical main keel 10 and fixed by bolts, and the other end is welded and fixed to the horizontal main keel 20 in the prefabrication factory. Prefabrication in the factory can improve the accuracy of components, reduce construction difficulty, and improve construction efficiency.

[0055] In some embodiments, two groups of fixing bolts 62 are provided, one group of fixing bolts 62 is provided along the direction of the transverse main keel 10 , and the other group of fixing bolts 62 is provided perpendicular to the transverse main keel 10 ; the two groups of fixing bolts 62 are provided orthogonally and are both passed through the groove-shaped connecting plate 61 and the vertical main keel 20 .

[0056] The orthogonally arranged fixing bolts 62 can provide a more evenly distributed force, thereby improving the stability and deformation resistance of the overall structure. Enhanced connection strength: The orthogonally arranged fixing bolts 62 can resist both tensile and shear forces. This can effectively prevent the relative displacement between the horizontal main keel 10 and the vertical main keel 20, ensuring the integrity of the firewall. In addition, the orthogonally arranged fixing bolts 62 help to evenly distribute the load to the connecting parts, reduce stress concentration, and extend the service life of the structure.

[0057] In some embodiments, the second connecting assembly 70 includes an end plate 71 and a self-tapping screw 72; the end plate 71 is welded to the secondary keel 30; the self-tapping screw 72 is passed through the end plate 71 and the transverse main keel 10 to fix the end plate 71 and the transverse main keel 10 together.

[0058] The end plate 71 and the secondary keel 30 are welded to each other, so that the end plate 71 is fixed to the secondary keel 30 , and the secondary keel 30 and the transverse main keel 10 can be connected to each other through the end plate 71 .

[0059] When the secondary keel 30 and the transverse main keel 10 need to be connected to each other, the secondary keel 30 can be set on the transverse main keel 10. At this time, the end plate 71 is located on the transverse main keel 10, and then it can be connected to the transverse main keel 10 through the self-tapping screws 72, so that the transverse main keel 10 and the transverse plate are fixed to each other, so that the transverse main keel 10 and the secondary keel 30 are fixedly connected to each other.

[0060] Specifically, the end plate 71 and the secondary keel 30 can be welded in the factory and then directly assembled and installed on site. With such a configuration, when the secondary keel 30 and the transverse main keel 10 need to be installed on site, the transverse main keel 10 can be directly connected to the end plate 71 by the self-tapping screws 72, so that the secondary keel 30 welded to the end plate 71 can be connected to the transverse main keel 10. In this case, there is no need to weld the end plate 71 on site, which can greatly save assembly time.

[0061] In some embodiments, a plurality of fireproof panels 40 are provided, and the widths of the plurality of fireproof panels 40 are the same as the spacing between the secondary keels 30 .

[0062] By providing the fireproof panels 40 in a plurality of pieces, and providing the plurality of fireproof panels 40 between the secondary keels 30, the fireproof panels 40 can be fixed between the secondary keels 30. With such a configuration, the fireproof panels 40 can be placed between the secondary keels 30 more conveniently during installation, thus simplifying the installation steps. In addition, the space utilization between the secondary keels 30 is maximized, thus avoiding unnecessary space waste.

[0063] In some embodiments, the fireproof cotton 50 is disposed between the fireproof boards 40 on both sides, and the thickness of the fireproof cotton 50 is equal to the distance between the fireproof boards 40 on both sides. The fireproof cotton 50 can be located between the fireproof boards 40 on both sides, and by setting the thickness of the fireproof cotton 50 to be the same as the thickness of the fireproof boards 40 on both sides, the fireproof boards 40 on both sides can be clamped together by the fireproof cotton 50, thereby fixing the fireproof cotton 50 to prevent the fireproof cotton 50 from falling off.
