Description

Technical Field

[0001] This utility model relates to the field of fireproof sealing construction technology for curtain walls, and in particular to a fireproof skirt wall fixing seat for steel structure building beams that does not require welding. Background Technology

[0002] Fire-stopping design of curtain walls is a crucial aspect of building fire protection. Relevant standards and specifications require that, under normal circumstances, glass curtain walls without window sills should have a non-combustible solid skirt wall or fire-resistant glass skirt wall with a fire resistance rating of not less than 1.0 hour and a height of not less than 0.8 meters installed along the outer edge of each floor slab. When the building height exceeds 250 meters, a non-combustible solid wall with a height of not less than 1.5 meters is required, and its height above the floor slab should not be less than 0.6 meters. Figure 1 As shown, the existing steel structure beam 10 is an I-beam with a height of less than 0.8m, therefore a non-combustible solid skirt wall needs to be added below it. The existing non-combustible solid skirt wall is made using a new type of fireproof skirt wall 1, which has the advantages of simple structure, light weight and convenient construction.

[0003] like Figure 1-2 As shown, the new fireproof skirt wall 1 includes: a supporting steel plate 11, a fireproof and heat-insulating board 12, and directional expansion cotton strips 13. The supporting steel plate 11 is bent into a corresponding structural shape, such as a right-angle structure, according to the position and connection relationship between the steel structure building beam 10 and the curtain wall 20; the bent edges 111 formed at both ends are connected to the exposed frame crossbars 201 of the steel structure building beam 10 and the curtain wall 20, respectively. The fireproof and heat-insulating board 12 is fixed to the inner side of the supporting steel plate 11 by heat-insulating welding studs 14, so that the fireproof and heat-insulating board 12 and the supporting steel plate 11 are an integral structure. The directional expansion cotton strips 13 are fixed between the supporting steel plate 11 and the steel structure building beam 10, and between the supporting steel plate 11 and the exposed frame crossbars 201 of the curtain wall 20. The directional expansion cotton strips 13 are fixed to the outer side of the bent edges 111 of the supporting steel plate 11 by double-sided adhesive. The new fireproof skirt wall 1 is fixedly installed on the steel structure building beam 10 after screws pass through the bent edge 111 and the directional expansion cotton strip 13 at the end of the supporting steel plate 11 in sequence. The bent edge 111 and the directional expansion cotton strip 13 at the other end of the supporting steel plate 11 abut or overlap on the exposed frame horizontal bar 201 of the curtain wall 20.

[0004] The existing installation method for the new type of fireproof skirt wall 1 involves welding a steel pipe as a mounting base under the steel structure beam 10 or drilling holes in the lower flange of the steel structure beam 10, and then connecting the supporting steel plate 11 to the mounting base or the steel structure beam. However, welding or drilling holes in the steel structure beam 10 will affect the strength of the beam. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] A fireproof skirt wall fixing bracket for steel structure building beams, combined with Figure 3 , Figure 4 and Figure 5 As shown, the device includes a clamping component 31, which has a receiving groove 34 for inserting the edge of the lower flange of the steel structure beam. The clamping component 31 also has a locking member 32 for adjusting the distance between the bottom surface of the lower flange of the steel structure beam and the lower side wall of the receiving groove 34. When the locking member 32 is locked, it presses the bottom surface of the lower flange of the steel structure beam against the lower side wall of the receiving groove 34. This application achieves clamping and fixing of the clamping component 31 onto the steel structure beam by operating the locking member 32 to press the bottom surface of the lower flange of the steel structure beam against the lower side wall of the receiving groove 34, avoiding welding or drilling on the steel structure beam and thus not affecting the beam's strength. It also simplifies the installation process and improves installation efficiency.

[0028] Preferably, the locking component 32 includes a tightening bolt 321 threadedly connected to the locking member 31. The threaded end of the tightening bolt 321 passes into the receiving groove 34 or into the space extending from the receiving groove 34 to both ends. Tightening the tightening bolt 321 increases the length of the head of the tightening bolt 321 into the receiving groove 34 or into the space extending from the receiving groove 34 to both ends. The head of the tightening bolt 321 pushes against the upper bottom surface of the lower flange of the steel structure building beam until the lower bottom surface of the lower flange of the steel structure building beam is pressed against the lower side wall of the receiving groove 34.

[0029] Preferably, the clamping component 31 includes a lower rod 311, a connecting rod 312, and an upper rod 313. The lower rod 311 and the upper rod 313 are arranged opposite to each other. The upper and lower parts of the connecting rod 312 are respectively fixedly connected to the upper rod 313 and the lower rod 311. The lower rod 311, the connecting rod 312, and the upper rod 313 form a receiving groove 34. This allows the size of the clamping component 31 to be reduced, making it easier to carry and handle during installation, and also helps to reduce production costs.

[0030] Specifically, the lower rod 311 and the upper rod 313 are arranged in parallel, and the connecting rod 312 is located at the ends of the lower rod 311 and the upper rod 313. The lower rod 311, the connecting rod 312 and the upper rod 313 form a "U"-shaped receiving groove 34.

[0031] Preferably, the lower sidewall of the receiving groove 34 is provided with an anti-slip structure 341 to improve connection reliability and prevent detachment.

[0032] Specifically, the anti-slip structure 341 can be made by machining serrated anti-slip patterns on the lower sidewall of the receiving groove 34 (i.e., the upper surface of the lower rod 311).

[0033] Preferably, the locking component 32 further includes a connecting nut 322 threadedly connected to the tightening bolt 321. At least two connecting nuts 322 are fixedly installed on both sides of the upper rod 313 by welding. The screw end of the tightening bolt 321 passes through the connecting nut 322 and enters the space extending from the receiving groove 34 to both ends. Through the cooperation of at least two sets of tightening bolts 321 and connecting nuts 322, warping is prevented, ensuring that the clamp 31 makes surface contact with the lower flange of the steel structure beam, thus enabling the clamp 31 to be reliably installed on the lower flange of the steel structure beam.

[0034] Preferably, a skirt wall support plate 33 is also fixedly mounted on the clip 31, and the skirt wall support plate 33 and the lower bottom surface of the lower flange of the steel structure building beam form a skirt wall hanging joint 35 for suspending the new fireproof skirt wall. After the clips 31 of the two fixing seats are installed at intervals, the new fireproof skirt wall is suspended by directly inserting the bent edge 111 of the new fireproof skirt wall into the skirt wall hanging joint 35. In this embodiment, the skirt wall support plate 33 is fixedly installed at the end of the lower rod 311 away from the connecting rod 312.

[0035] Specifically, the lower sidewall of the receiving groove 34 (i.e. the upper surface of the lower rod 311) is parallel to and higher than the upper surface of the skirt wall support plate 33, so that when the lower bottom surface of the lower flange of the steel structure building beam is pressed against the lower sidewall of the receiving groove 34, the upper surface of the skirt wall support plate 33 and the lower bottom surface of the lower flange of the steel structure building beam are separated by a gap, thus forming the skirt wall hanging joint 35. The new fireproof skirt wall can be extended from the skirt wall hanging joint 35 and hung on the skirt wall support plate 33.

[0036] Preferably, the skirt wall support plate 33 is provided with a buckle assembly for snapping and fixing the new fireproof skirt wall, so as to improve the reliability of the connection of the new fireproof skirt wall and avoid displacement along the width direction when the new fireproof skirt walls overlap.

[0037] Preferably, the snap-fit ​​assembly includes a slot 37 opened on the skirt wall support plate 33, and the bent edge 111 forms a hook that hooks into the slot 37, thereby limiting the position of the new fireproof skirt wall and preventing the new fireproof skirt wall from tilting. While ensuring that the new fireproof skirt wall is reliably suspended, it can also enable the new fireproof skirt wall to move along the slot 37, which facilitates the overlapping of the new fireproof skirt wall.

[0038] Preferably, the snap-fit ​​assembly includes multiple slots 37, which are arranged along the width direction of the lower flange of the steel structure building beam. By hooking the bent edge 111 into different slots 37, the position of the new fireproof skirt wall along the width direction of the lower flange of the steel structure building beam can be adjusted, thereby adjusting the distance between the new fireproof skirt wall and the exposed frame crossbar 201 of the curtain wall 20. In this embodiment, the multiple slots 37 are several parallel and spaced rectangular grooves machined on the upper surface of the skirt wall support plate 33.

[0039] Preferably, the clamp 31 is fixedly provided with a connecting assembly for hooking the inclined steel wire rope 4, the connecting assembly including several connectors 36. By hooking one end of the inclined steel wire rope 4 onto the connector 36 and fixing the other end to the new fireproof skirt wall with screws, the sagging of the new fireproof skirt wall can be prevented. In this embodiment, there are multiple connectors 36. By hooking one end of the inclined steel wire rope 4 onto different connectors 36, the tension of the inclined steel wire rope 4 can be adjusted to ensure the horizontality of the new fireproof skirt wall. It can be understood that only one connector 36 can be provided, and the tension of the inclined steel wire rope 4 can be adjusted by using a tensioner. In this embodiment, the connector 36 is designed in a hook shape for easy installation of the inclined steel wire rope 4.

[0040] For fire-resistant skirt walls with a width of 300mm or less, this application allows for independent suspension by directly hooking the bent edge 111 into the slot 37. Even if the curtain wall is damaged by fire, the fire-resistant skirt wall can still be reliably suspended without affecting the fire-sealing effect. For fire-resistant skirt walls with a width greater than 300mm, to prevent excessive cantilever length and sagging, only a diagonal steel wire rope 4 is added to hold the fire-resistant skirt wall in place. This ensures that the fire-resistant skirt wall remains balanced under the combined action of the hook of the bent edge 111 into the slot 37 and the diagonal steel wire rope 4, thus guaranteeing the independent suspension of the fire-resistant skirt wall.

[0041] Specifically, the card 31, the skirt wall support plate 33, and the connector 36 are integrally formed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
