Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated decoration, and particularly relates to a connecting structure for a steel beam fireproof board and a method for connecting and covering a steel beam with a fireproof board. Background Art

[0002] In steel structure buildings, the fireproofing and cold bridge problems of steel columns have always been important factors hindering the development of steel structure residences. A cold bridge mainly refers to when heat conduction occurs between the building's exterior envelope structure and the outside world. Due to the heat transfer coefficient of some parts of the envelope structure being significantly greater than that of other parts, heat is concentrated and rapidly transferred from these parts, thereby increasing the air conditioning, heating load, and energy consumption of the building.

[0003] Currently, when arranging steel structure buildings, components such as beams and columns protrude from the steel structure wall. When fireproofing the steel structure building, separate fireproof treatment is required at the protruding beam and column components.

[0004] Chinese Utility Model Patent with Publication No. CN2769393Y discloses a fireproof board for building steel structures. By making the fireproof board into shapes such as L and C, the fireproof board is adhesively wrapped around the outer surface of the steel beam or steel column to protect the steel beam or steel column. However, the cost of this fireproof board is higher than that of ordinary straight fireproof boards during actual manufacturing, and the method of tightly wrapping the fireproof board around the steel column will result in a significant increase in the amount of fireproof board used and also increase the procurement cost of the fireproof board. Summary of the Invention

[0005] The present invention provides a connecting structure for a steel beam fireproof board, which is used to connect and fix an ordinary straight fireproof board outside the protruding beam and column components and form a complete covered fireproof structure to effectively reduce the fireproof cost of steel structure buildings and solve the above technical problems.

[0006] The technical solution of the present invention to solve the above problems is: to provide a connecting structure for a steel beam fireproof board, including a first connecting plate and a second connecting plate that are perpendicularly connected to each other. At least one adhesive groove is provided on the surface of the first connecting plate facing away from the second connecting plate. The second connecting plate includes a first fixing plate and a second fixing plate. At least one adhesive groove is also provided on the surface of the first fixing plate facing away from the first connecting plate, and a bending crease is provided on the second fixing plate. The second fixing plate can be bent at the bending crease to swing to be parallel to the first connecting plate or horizontally coincide with the first fixing plate.

[0007] Further, overflow glue through holes are provided on both the first connecting plate and the first fixing plate.

[0008] Further, the overflow glue through holes are provided at the bottom of the adhesive groove.

[0009] Further, a plurality of glue overflow through holes are provided at the bottom of each of the bonding grooves, and the plurality of glue overflow through holes are equidistantly arranged.

[0010] Further, at least one nailing groove is provided on each of the first connecting plate and the first fixing plate.

[0011] Further, the nailing groove and the bonding groove are respectively arranged on two sides of the first connecting plate or the first fixing plate.

[0012] Further, the groove depths of the nailing groove and the bonding groove are the same.

[0013] The present invention also provides a method for connecting and covering a steel beam fireproof board, using the steel beam fireproof board connecting structure described in any one of the above, and the installation steps are as follows:

[0014] S1: Bend the second fixing plates of the two steel beam fireproof board connecting structures to positions horizontally coincident with their first fixing plates, and then fixedly install them at positions on both sides of the protruding steel beam member close to the wall; wherein, the structure corresponding to the steel beam member welded to the steel beam fireproof board connecting structure is the second connecting plate.

[0015] S2: Bend the second fixing plates of the two steel beam fireproof board connecting structures to positions parallel to their first connecting plates, and then fixedly install them at positions on both sides of the outer ends of the protruding steel beam member; wherein, the structure corresponding to the steel beam member welded to the steel beam fireproof board connecting structure is the second fixing plate.

[0016] S3: Fill rock wool in the cavity formed by the cooperation of the four steel beam fireproof board connecting structures and the protruding steel beam member.

[0017] S4: Install the fireproof board in a surrounding manner on the outside of the protruding steel beam member, and each fireproof board is fixedly connected to at least two fireproof board connecting structures. Among them, the structure corresponding to the steel beam fireproof board connecting structure fixedly connected to each fireproof board is the first connecting plate or the first fixing plate.

[0018] Further, after installing all the fireproof boards, install fireproof sealing at the positions where the fireproof boards contact the wall, and set fireproof sealing gaskets at the positions where the fireproof boards contact each other.

[0019] The beneficial effects of the present invention:

[0020] 1. When the second fixed plate is bent to be parallel to the first connecting plate, the device of the present invention can be welded and fixed to the outer end face side of the protruding steel beam member through its second fixed plate correspondingly. At this time, the first fixed plate and the first connecting plate are perpendicular to each other and can be respectively fixedly connected to a fireproof board. When the second fixed plate is bent to be horizontally overlapped with the first fixed plate, the device of the present invention is welded to the steel beam member directly on the side against the wall through the second connecting plate, and its first connecting plate is exactly perpendicular to the wall and located on one side of the steel beam member, so as to facilitate the fixed connection of the side of the fireproof board against the wall. That is to say, the construction personnel can manually adjust the actual structural form of the steel beam fireproof board connection structure so that it can be correspondingly installed on both sides against the wall or both outer end face sides of the steel beam member, thereby providing a fixed foundation for the wrapped installation of the fireproof board and reducing the construction cost.

[0021] 2. The fireproof board and the steel beam fireproof board connection structure are fixedly connected by gluing and nailing. Among them, during gluing, the bonding groove can accommodate the adhesive, thereby avoiding excessive adhesive solidifying and increasing the gap between the fireproof board and the steel beam fireproof board connection structure, and avoiding the installation inclination of the fireproof board caused by different gaps at both ends of the fireproof board.

[0022] 3. When there is too much adhesive and the bonding groove cannot accommodate it completely, the excess adhesive can also overflow from the glue overflow through hole, so as to further reduce the influence of the adhesive on the gap size between the fireproof board and the steel beam fireproof board connection structure.

[0023] 4. The setting of the nailing groove can facilitate the nailing and fixing of the fireproof board to the first fixed plate or the first connecting plate.

[0024] 5. Both the first fixed plate and the first connecting plate are plate bodies with the same thickness, and the bonding grooves and nailing grooves on them are formed by stamping, which is convenient for manufacturing.

[0025] 6. A method for wrapped connection of a steel beam fireproof board of the present invention is used to guide the installation of the fireproof board by enclosing three sides outside the protruding steel beam member and making adjacent fireproof boards closely connected, so that the fireproof board can efficiently isolate and protect the steel beam member.

[0033] In this specification, the orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned are defined relative to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0034] In a steel structure building, when part of the steel beam member 10 protrudes from the wall 7, the original fireproof board installation design scheme cannot be implemented at the protruding steel beam member 10 because the problem of the installation protrusion of the steel beam member 10 is not fully considered, resulting in the need for separate installation of the fireproof board 8 on the outside of the protruding steel beam member 10. Since the existing fireproof board 8 used for installation at the protruding steel beam member 10 is usually a C-shaped board, although it has good heat insulation performance, its corresponding manufacturing cost is relatively high.

[0035] In response to this, a specific embodiment of the present invention provides a steel beam fireproof board connection structure. The traditional low-cost straight fireproof board 8 can be fixed to the outside of the protruding steel beam member 10 through this connection structure, and the fireproof boards 8 installed with three-sided enclosures can also be tightly fixed to each other through this connection structure. The splicing gaps between the three-sided fireproof boards 8 are basically close to zero under the fixed connection of the connection structure of this device, so that the low-cost straight fireproof board 8 can also completely isolate the protruding steel beam member 10 from the outside when installed with three-sided enclosures, ensuring its heat insulation and fireproof performance.

[0036] The steel beam fireproof board connection structure 6 of the specific embodiment of the present invention includes a first connecting plate 1 and a second connecting plate 2 that are perpendicularly connected to each other. The first connecting plate 1 and the second connecting plate 2 are integrally connected and the whole is in an "L" shape, and both are metal plate bodies. Among them, a through-cut mark is formed in the middle of the end of the second connecting plate 2 that is farther away from the first connecting plate 1 and extends toward the first connecting plate 1. This through-cut mark does not extend to the first connecting plate 1. Therefore, the through-cut mark can correspondingly divide the second connecting plate 2 into a first fixed plate 21 and a second fixed plate 22 that are still connected to each other near the first connecting plate 1. The second fixed plate 22 can be bent so that the included angle between it and the first fixed plate 21 can be adjusted, and thus the overall shape of the steel beam fireproof board connection structure 6 of this embodiment can be changed from an "L" shape to an "F" shape.

[0037] In this embodiment, in order to facilitate bending the second fixed plate 22 and accurately control the bending part of the second fixed plate 22, a concave bending crease 23 is correspondingly formed on the second fixed plate 22. The upper end of the bending crease 23 is connected to one end of the through-cut mark close to the first connecting plate 1, and the bending crease 23 is perpendicular to the through-cut mark.

[0038] As Figure 1 , Figure 3 , Figure 4 shown, when the second fixed plate 22 is flush with the first fixed plate 21, the overall steel beam fireproof board connection structure 6 of this embodiment is in an "L" shape. At this time, the steel beam fireproof board connection structure 6 in the "L" shape can be correspondingly fixedly installed on both sides of the protruding steel beam member 10 against the wall for fixing the wall-side ends of the two fireproof boards 8. Taking the I-shaped steel beam member 10 as an example, when the steel beam fireproof board connection structure 6 is installed on one side of the protruding steel beam member 10 against the wall, the second connecting plate 2 of the steel beam fireproof board connection structure 6 is fixed to the inner side of the steel beam member 10 by welding. At the same time, its first connecting plate 1 is correspondingly perpendicular to the wall 7, and the exposed side surface of the first connecting plate 1 is correspondingly flush with the two side surfaces of the steel beam member 10. The fireproof board 8 is correspondingly fixed and connected to the first connecting plate 1 by means of bonding + nailing.

[0039] To further improve the installation quality of the fireproof board 8, a plurality of bonding grooves 3 are equidistantly formed on the exposed surface of the first connecting plate 1 facing away from the second connecting plate 2, and the bonding grooves 3 are sunken in the first connecting plate 1. Moreover, an overflow glue through-hole 4 is correspondingly formed on the first connecting plate 1 at each bonding groove 3, and the overflow glue through-hole 4 communicates with the bonding groove 3. When bonding the fireproof board 8 to the first connecting plate 1, the operator can place glue in the bonding groove 3 correspondingly, and then press the fireproof board 8 tightly against the first connecting plate 1 until the glue solidifies. At this time, since the glue is all in the bonding groove 3 and will flow out from the overflow glue through-hole 4 when there is more glue in the bonding groove 3, it will not remain on the exposed surface of the first connecting plate 1, so that there is no glue mixture between the first connecting plate 1 and the fireproof board 8, which is convenient for controlling the installation accuracy of the fireproof board 8.

[0040] In addition, to facilitate the nailing operation, a plurality of nailing grooves 5 are provided on the inner side of the first connecting plate 1, and the nailing grooves 5 and the adhesive grooves 3 are staggered on both sides of the first connecting plate 1 to prevent the nailing grooves 5 and the adhesive grooves 3 from overlapping inside and outside the first connecting plate 1, resulting in a very small thickness of the first connecting plate 1 at the overlapping position, which affects the structural strength of the first connecting plate 1. In this way, the first connecting plate 1 can even directly use a conventional straight plate, and the nailing grooves 5 and the adhesive grooves 3 thereon can be formed by stamping operations.

[0041] See also Figure 2 , Figure 3 , Figure 4 When the second fixing plate 22 is bent to be perpendicular to the first fixing plate 21, the second fixing plate 22 is also exactly parallel to the first connecting plate 1; at this time, the "F"-shaped steel beam fireproof board connection structure 6 can be fixedly installed on both sides of the protruding end surface of the protruding steel beam component 10, and can be used to fix the far wall ends of the fireproof boards 8 on both sides, as well as for fixing the third fireproof board 8. Taking the I-shaped steel beam component 10 as an example, two "F"-shaped steel beam fireproof panel connection structures 6 can be welded and fixed at the left and right sides of the protruding end face of the protruding steel beam component 10 through their second fixing plates 22. At this time, the first connecting plate 1 can extend to the side of the protruding steel beam component 10 and is perpendicular to the wall 7, and the first fixing plate 21 is correspondingly located at the protruding end face of the protruding steel beam component 10, and the two first fixing plates 21 located at the protruding end face of the protruding steel beam component 10 and the two second fixing plates 22 respectively welded and fixed cooperate with each other to form an enclosure structure. When the third fireproof panel 8 is fixedly installed, a cavity is formed to separate the protruding end face of the protruding steel beam component 10 from the fireproof panel 8 to weaken heat transfer.

[0042] Similarly, in order to improve the installation quality of the fireproof board 8, a plurality of bonding grooves 3 are equidistantly provided on the exposed surface of the first fixing plate 21 facing away from the first connecting plate 1, and the bonding grooves 3 are sunken into the first fixing plate 21; moreover, a corresponding glue overflow through hole 4 is provided on the first fixing plate 21 at each bonding groove 3, and the glue overflow through hole 4 is connected to the bonding groove 3. When bonding the fireproof board 8 to the first fixing plate 21, the operator can put glue in the bonding groove 3, and then press the fireproof board 8 onto the first fixing plate 21 until the glue solidifies. At this time, since the glue is all in the bonding groove 3, and when there is more glue in the bonding groove 3, it will flow out from the glue overflow through hole 4, and it will not remain on the exposed surface of the first fixing plate 21, so that there is no glue mixed between the first fixing plate 21 and the fireproof board 8, so as to control the installation accuracy of the fireproof board 8.

[0043] In addition, for the convenience of stapling operation, a plurality of stapling grooves 5 are provided inside the first fixing plate 21, and the stapling grooves 5 and the bonding grooves 3 are staggered on both sides of the first fixing plate 21 to prevent the stapling grooves 5 and the bonding grooves 3 from overlapping inside and outside on the first fixing plate 21, resulting in an extremely small thickness of the first fixing plate 21 at the overlapping position, which affects the structural strength of the first fixing plate 21. In this way, the first fixing plate 21 and even the second connecting plate 2 can directly use conventional straight plates, and the stapling grooves 5 and the bonding grooves 3 thereon can be formed by stamping operations.

[0044] In this embodiment, the groove depth dimensions of the stapling grooves 5 and the bonding grooves 3 are the same.

[0045] The specific embodiment of the present invention further includes a method for connecting and covering a steel beam fireproof board. Using the steel beam fireproof board connection structure described in any one of the above, the installation steps are as follows:

[0046] S1: Bend the second fixing plates 22 of the two steel beam fireproof board connection structures 6 to a position horizontally coincident with their first fixing plates 21, and then fixedly install them at the positions on both sides of the protruding steel beam member 10 against the wall; wherein, the structure of the steel beam fireproof board connection structure 6 corresponding to being welded to the steel beam member 10 is the second connecting plate 2;

[0047] S2: Bend the second fixing plates 22 of the two steel beam fireproof board connection structures 6 to a position parallel to their first connecting plates 1, and then fixedly install them at the positions on both sides of the outer ends of the protruding steel beam member 10; wherein, the structure of the steel beam fireproof board connection structure 6 corresponding to being welded to the steel beam member 10 is the second fixing plate 22;

[0048] S3: Fill rock wool 9 into the cavity formed by the cooperation of the four steel beam fireproof board connection structures 6 and the protruding steel beam member 10;

[0049] S4: Install fireproof boards 8 in a surrounding manner outside the protruding steel beam member 10, and each fireproof board 8 is fixedly connected to at least two fireproof board connection structures. Among them, the structure of the steel beam fireproof board connection structure 6 corresponding to being fixedly connected to each fireproof board 8 is the first connecting plate 1 or the first fixing plate 21.

[0050] It should be added that after all the fireproof boards 8 are installed, fireproof sealing is installed at the positions where the fireproof boards 8 contact the wall 7, and fireproof sealing gaskets are provided at the positions where the fireproof boards 8 contact each other.

[0051] For those not mentioned above, the prior art applies.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
