Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel beam fire protection, and particularly relates to a fireproof device for a full-bolted energy dissipation steel beam and a mounting method. BACKGROUND

[0002] Nowadays, steel frame structures are used more and more widely. In addition, the structure design emphasizes "strong nodes and weak members". Therefore, the safety and reliability of the beam-column splicing joints in steel structures also need to be continuously improved to adapt to the current industry status. Steel is a material that is relatively sensitive to temperature. Temperature rise has a huge impact on the strength and deformation of steel. Without fireproof coating, ordinary construction steel almost loses its load-bearing capacity when the temperature reaches 600 DEG C. Once a fire occurs, a steel structure building will collapse rapidly, causing a disastrous accident and endangering people's lives and property.

[0003] The existing fire protection measures for steel structures include spraying fireproof coating, externally applying decorative panels, and wrapping beams with fireproof insulation boards, etc. For example, CN213204462U is a kind of assembled steel structure building H steel beam fireproof and decorative cladding joint. Through the clamping of the upper connecting folding frame and the lower connecting folding frame on the H steel beam, the upper through hole and the lower through hole are matched and combined to replace the traditional H steel beam fixed by welding.

[0004] However, the existing protection methods are either complex in construction process or require a large amount of materials for fire protection measures, and the cost is relatively high. In addition, some protection methods do not involve the bolt group at the connection of the steel beam, and still have the hidden danger of uneven spraying of fireproof coating on the surface of the bolt group. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a fireproof device for a full-bolted energy dissipation steel beam and a mounting method, which is convenient to construct and eliminates the hidden danger of uneven spraying of fireproof coating on the bolt group of the steel beam.

[0009] A first folding edge is arranged on the side of the guard wall away from the top plate, and the first folding edge is used for being inserted between the flange plate of the bolt group and the steel beam.

[0010] To solve the above technical problems, another technical solution adopted by the present application is:

[0014] S3, after the protective cover covers the bolt group, folding the protective wall corresponding to the opening, covering the opening while inserting the first folded edge of the protective wall corresponding to the opening into the gap.

[0024] In order to explain the technical content, the purpose and effect of the present application in detail, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0025] Please refer to Figures 1 to 5 A fireproof equipment for a full-bolted energy dissipation steel beam, comprising a protective cover for covering the bolt group 3 on the steel beam 1, the surface of the protective cover is uniformly coated with fireproof material;

[0026] The protective cover is composed of a top plate 6 and at least two guard walls 7 arranged along the edge of the top plate 6, at least one of the guard walls 7 can be arranged to be folded relative to the top plate 6 to form an opening 8 for the bolt group 3 to enter and exit the protective cover from the side edge of the protective cover;

[0027] The guard wall 7 is provided with a first folding edge 9 on the side away from the top plate 6, and the first folding edge 9 is used for inserting between the flange plate 4 of the bolt group 3 and the steel beam 1.

[0028] From the above description, the beneficial effects of the present application are that a fireproof equipment for a full-bolted energy dissipation steel beam is provided, which uses a protective cover with a surface uniformly coated with fireproof material to wrap the bolt group 3 on the steel beam 1, and the installation is realized by the cooperation of the folding structure and the first folding edge 9. During installation, the first folding edge 9 at the bottom of the guard wall 7 is inserted into the gap 5 between the flange plate 4 and the steel beam 1, thereby fixing the entire protective cover. It is ingeniously matched with the structural characteristics of the bolt group 3, not only the equipment cost is low, but also the construction and installation are convenient, and the hidden dangers caused by uneven spraying of fireproof paint on the bolt group 3 of the steel beam 1 can be effectively eliminated.

[0029] Further, the protective cover is divided into a first protective cover 10 arranged on the bottom surface of the steel beam 1 and a second protective cover 11 arranged on the side surface of the steel beam 1;

[0030] The shape and size of the top plate 6 of the first protective cover 10 are matched with the shape and size of the flange plate 4 of the bolt group 3 located on the bottom surface of the steel beam 1;

[0031] The width of the top plate 6 of the second protective cover 11 is adapted to the height of the steel beam 1, and the shape and size of the side edges of the top plate 6 and the side walls 7 on the opposite side are adapted to the shape and size of the beam groove 2 of the side of the steel beam 1.

[0032] As can be seen from the above description, different protective covers are arranged for different bolt groups 3 on the steel beam 1, which improves the fitting degree of the protective cover on the steel beam 1, makes the steel beam 1 with fireproof equipment more compact and beautiful in structure, and has better fireproof performance.

[0033] Further, the top plate 6 and the side walls 7 are integrally formed, and all the side walls 7 can be foldably arranged relative to the top plate 6.

[0034] As can be seen from the above description, all the side walls 7 can be foldably arranged relative to the top plate 6, that is, the fireproof equipment is designed to be flexible and foldable, which is convenient for storage, and can be folded in advance during daily installation, thereby simplifying the installation process, improving the installation efficiency, and being convenient and flexible to use.

[0035] Further, one of the side walls 7 is provided with a second folding edge 12 on the side edge close to the other side wall 7.

[0036] When the protective cover is formed, the second folding edge 12 abuts on one side of the other side wall 7 facing the inside of the protective cover.

[0037] As can be seen from the above description, the second folding edge 12 is arranged on the side edge of the side wall 7, which is used to tightly abut on the inner side of the other side wall 7 when the protective cover is formed, which can form friction resistance on the side wall 7 through the second folding edge 12, so that the side wall 7 is not easy to be folded back to cause the protective cover to fail to protect, and on the other hand, the sealing performance and structural strength of the joint of the side wall 7 and the side wall 7 are improved, so that the protection of the protective cover is more stable and reliable.

[0038] Further, the top plate 6, the side walls 7 and the first folding edge 9 are thin steel plates.

[0039] Further, the thickness of the thin steel plate is 2-3mm.

[0040] As can be seen from the above description, the protective cover is made of a thin steel plate with a thickness of 2-3mm, which has a certain hardness and is light in weight and easy to deform.

[0041] Please refer to Figures 1 to 6 A fireproof equipment installation method of a full-bolted energy-consuming steel beam, applied to the fireproof equipment of the full-bolted energy-consuming steel beam, comprising the following steps:

[0042] S1, adjust the bolt group 3 of the steel beam 1, leave a gap 5 between the flange plate 4 of the bolt group 3 and the steel beam 1;

[0043] S2, move the protective cover so that the bolt group 3 enters the protective cover from the opening 8 of the protective cover, and insert the first folding edge 9 of the remaining protective walls 7 except the protective wall 7 corresponding to the opening 8 into the gap 5;

[0044] S3, after the protective cover covers the bolt group 3, fold the protective wall 7 corresponding to the opening 8, cover the opening 8 while inserting the first folding edge 9 of the protective wall 7 corresponding to the opening 8 into the gap 5.

[0045] From the above description, the beneficial effects of the present application are that a fireproof equipment installation method of a full-bolted energy-consuming steel beam is provided, the bolt group 3 on the steel beam 1 is wrapped with a protective cover uniformly coated with a fireproof material, and the installation is specifically realized by the cooperation of the folding structure and the first folding edge 9. During installation, the first folding edge 9 at the bottom of the protective wall 7 is inserted into the gap 5 between the flange plate 4 and the steel beam 1, thereby fixing the entire protective cover. The structure characteristics of the bolt group 3 are ingeniously matched, the equipment cost is low, the construction and installation are convenient, and the hidden dangers caused by uneven spraying of fireproof paint on the bolt group 3 of the steel beam 1 can be effectively eliminated.

[0046] Further, the step S1 further includes the following steps before the step S1:

[0047] S0, fold the remaining protective walls 7 except the protective wall 7 corresponding to the opening 8 on the top plate 6 to form the protective cover.

[0048] From the above description, the protective wall 7 can be folded relative to the top plate 6, that is, the fireproof equipment is designed to be flexibly foldable, which is convenient for storage, and can be folded in advance during daily installation, thereby simplifying the installation process, improving the installation efficiency, and being convenient and flexible to use.

[0049] Further, the step S2 specifically includes:

[0050] When installing the second protective cover 11, the first folding edge 9 of the second protective cover 11 is inserted into the gap 5 of the bolt group 3 located in the beam groove 2 of the steel beam 1 and belonging to the top surface or the bottom surface of the steel beam 1.

[0051] From the above description, when the second protective cover 11 is installed on the side edge of the steel beam 1, the gap 5 between the flange plate 4 of the bolt group 3 and the steel beam 1 on the top surface and the bottom surface of the steel beam 1 can be fully utilized as a fixing basis, and a sealing structure wrapping the bolt group 3 is formed by the second protective cover 11 and the beam groove 2, so that the protective cover and the steel beam 1 have higher matching degree and are more convenient to install.

[0052] Further, the step S0 specifically comprises:

[0053] The second fold 12 on the wall 7 is folded inwardly so that the second fold 12 is tightly attached to the inward side of the adjacent wall 7.

[0054] From the above description, the second fold 12 is used to tightly attach the second fold 12 to the inward side of the adjacent wall 7 when forming the protective cover, which on one hand can form a frictional resistance to the wall 7 through the second fold 12, so that the wall 7 is not easy to be folded back to reset and cause the protection of the protective cover to be invalid, and on the other hand can increase the sealing performance and structural strength of the joint between the wall 7 and the wall 7, so that the protection of the protective cover is more stable and reliable.

The second fold edge 12 is located at the right-angle corner of the ring-shaped protective structure. When the protective cover is formed, the second fold edge 12 abuts on the side of the adjacent another guard wall 7 facing the inside of the protective cover. Moreover, in order to facilitate folding, folding indication lines are arranged between the top plate 6 and the guard walls 7, between the guard walls 7 and the first fold edges 9, and between the guard walls 7 and the second fold edges 12.
