Description

Technical Field

[0001] This utility model relates to the field of fireproof sealing structure technology for curtain walls, and in particular to an adjustable fixing seat for fireproof skirt walls used in concrete building beams. 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, when the height of the existing concrete building beam 10 is less than 0.8m, 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 concrete 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 concrete 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 concrete 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 concrete 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 drilling holes under the concrete building beam 10 and fixing the support plate with expansion bolts, and then connecting the supporting steel plate 11 to the support plate. However, its disadvantage is that construction workers need to hold it up for a long time to fix it during the installation of the new type of fireproof skirt wall 1. Utility Model Content

[0005] This utility model provides an adjustable fixing seat for a fireproof skirt wall used in concrete building beams to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An adjustable mounting base for a fireproof skirt wall for concrete building beams includes a mounting plate for connecting the concrete building beams.

[0008] A skirt wall support plate is provided on one side of the fixed installation plate, and the skirt wall support plate and the surface of the concrete building beam form a skirt wall hanging joint for hanging the new fireproof skirt wall.

[0009] A transition connecting plate is provided between the fixed mounting plate and the skirt wall support plate to connect the two.

[0010] Preferably, the upper surface of the fixed mounting plate is parallel to and higher than the upper surface of the skirt wall support plate.

[0011] Preferably, the mounting plate is provided with expansion bolt holes, through which expansion bolts pass to fix the mounting plate to the concrete building beam.

[0012] Preferably, the expansion bolt holes are elongated holes, and the direction of the elongated holes is set along the direction of the fixed mounting plate toward the skirt wall support plate.

[0013] Preferably, at least two expansion bolt holes are provided and arranged in parallel.

[0015] Preferably, the snap-fit ​​assembly includes a slot opened on the skirt wall support plate, and the bent edge forms a hook that hooks into the slot.

[0016] Preferably, the snap-fit ​​assembly includes multiple slots, which are arranged along the width direction of the concrete building beam.

[0017] Preferably, the transition connecting plate is provided with a connecting component for hooking the inclined steel wire rope.

[0018] Preferably, the connecting component includes a lug, and the lug has a through hole.

[0019] Beneficial effects:

[0028] 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.

[0029] An adjustable fixing seat for fireproof skirting walls used in concrete building beams, combined with Figure 3 , Figure 4 and Figure 5As shown, the system includes a fixed mounting plate 21 for connecting the concrete building beam 10; a skirt wall support plate 22 is provided on one side of the fixed mounting plate 21, and the skirt wall support plate 22 and the surface of the concrete building beam 10 form a skirt wall hanging joint 24 for suspending the new fireproof skirt wall; a transition connecting plate 23 is provided between the fixed mounting plate 21 and the skirt wall support plate 22 to connect the two. By setting the fixed mounting plate 21 to connect the concrete building beam 10, and forming a skirt wall hanging joint 24 between the skirt wall support plate 22 and the surface of the concrete building beam 10 for suspending the new fireproof skirt wall, the new fireproof skirt wall can be directly suspended after connecting the concrete building beam 10 through the adjustable fixing seat, without the need to make a keel, simplifying the installation of the new fireproof skirt wall and avoiding long-term support by construction workers.

[0030] Preferably, the upper surface of the fixed mounting plate 21 is parallel to and higher than the upper surface of the skirt wall support plate 22. The upper surface of the fixed mounting plate 21 is used to fit the lower surface of the concrete building beam 10. The upper surface of the skirt wall support plate 22 is lower than the upper surface of the fixed mounting plate 21, so that the upper surface of the skirt wall support plate 22 and the lower surface of the concrete building beam 10 are separated by a certain distance to form a skirt wall hanging joint 24. The new fireproof skirt wall can be inserted through the skirt wall hanging joint 24 and hung on the skirt wall support plate 22.

[0031] Preferably, the mounting plate 21 is provided with expansion bolt holes 211, and the expansion bolts 3 pass through the expansion bolt holes 211 to fix the mounting plate 21 to the concrete building beam 10.

[0032] Preferably, the expansion bolt hole 211 is an elongated hole, and the direction of the elongated hole is set along the direction of the fixed mounting plate 21 toward the skirt wall support plate 22, so as to realize the adjustment of the position of the fixed mounting plate 21.

[0033] Preferably, at least two expansion bolt holes 211 are provided and arranged in parallel. In this embodiment, there are two expansion bolt holes 211, the transition connecting plate 23 is located in the middle of the fixed mounting plate 21, and the two expansion bolt holes 211 are located on both sides of the transition connecting plate 23.

[0034] Preferably, the skirt wall support plate 22 is provided with a snap-fit ​​component 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 when the new fireproof skirt walls overlap.

[0035] Preferably, the snap-fit ​​assembly includes a slot 25 opened on the skirt wall support plate 22, and the bent edge 111 forms a hook that hooks into the slot 25, 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 25, which facilitates the overlapping of the new fireproof skirt wall.

[0036] Preferably, the snap-fit ​​assembly includes multiple slots 25 arranged along the width direction of the concrete building beam 10. By hooking the bent edge 111 into different slots 25, the position of the new fireproof skirt wall along the width direction of the concrete building beam 10 can be adjusted, thereby adjusting the distance to the exposed frame crossbar 201. In this embodiment, the multiple slots 25 are several parallel and spaced rectangular grooves machined on the upper surface of the skirt wall support plate 22.

[0037] Preferably, the transition connecting plate 23 is provided with a connecting assembly for hooking the inclined steel wire rope 4. By connecting one end of the inclined steel wire rope 4 to the connecting assembly and fixing the other end to the new fireproof skirt wall with screws, the sag of the new fireproof skirt wall can be prevented. The tension of the inclined steel wire rope 4 can be adjusted by equipping it with a tensioner. When the lateral distance is greater than 300 mm, the sag of the new fireproof skirt wall is prevented by the pulling of the inclined steel wire rope 4.

[0038] 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 25. 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 25 and the diagonal steel wire rope 4, thus guaranteeing the independent suspension of the fire-resistant skirt wall.

[0039] Preferably, the connecting component includes a lug 5, which has a through hole, and the end of the inclined steel wire rope 4 is hooked into the through hole.

[0040] 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.
