Description
Technical Field
The utility model belongs to girder steel concatenation gap structure field, concretely relates to girder steel concatenation gap sound insulation fire prevention processing structure.
Background
For the beam with a steel structure, the whole steel beam cannot be welded on the upright column in the current processing mode. As shown in fig. 1-2, the general processing method is: girder steel connects 2 and welds on stand 1, and girder steel main part 3 rethread connecting plate 5 is fixed in girder steel and connects 2. Specifically, the connection plate holes 51 on the connection plate 5 are fixedly connected by the bolts 4 after being matched with the first perforation group 21 on the steel beam joint 2 and the second perforation group 31 on the steel beam main body 3. The steel beam joint welding process is convenient among the current processing scheme, and the connected mode that the girder steel main part connects with the girder steel is simple. At present, the mode of connecting the steel beam main body with the steel beam through the bolt can completely meet the structural strength without adding a fine welding process to a connecting gap. However, the connecting gap is disadvantageous for the fire protection and sound insulation effect. The sound insulation performance of one ten thousandth gaps on the wall surface is reduced by 10dB, and the connecting gaps can also become diffusion channels of toxic smoke in fire.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the technical problem who exists among the above-mentioned background art, providing a structure is handled in girder steel concatenation gap sound insulation fire prevention.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
a steel beam splicing gap sound and fire insulation treatment structure is required to be adhered with a fireproof rubber mud layer on two sides of a joint of a steel beam joint and a steel beam main body at the top of a treatment wall body. The fireproof rubber mud layer covers the steel beam joint and the two sides of the steel beam main body integrally. The fireproof rubber cement layer is adhered to the whole length of the beam. The waist thickness of the steel beam is only about 10mm generally, and the sound insulation effect needs to be increased. The adhesion of fire prevention rubber mud layer on whole crossbeam length has increased syllable-dividing and fire prevention effect.
The fireproof rubber mud layer is welded on the steel beam joint and the galvanized steel plate box on the steel beam main body to cover and wrap. The galvanized steel plate box slows down the aging of the fireproof rubber cement layer on one hand and is used as a fixing base of a subsequent structure on the other hand. Fill the fire prevention rubber mud layer in the connection gap of girder steel joint and girder steel main part, the putty of fire prevention rubber mud layer goes into the gap, reinforcing sound insulation and fire prevention effect.
The galvanized steel plate box is externally connected with a sound-proof felt layer, and a gypsum plate is arranged outside the sound-proof felt layer. The sound insulation felt layer separates the continuous hard connection among the gypsum board, the galvanized steel plate box and the steel beam, and improves the sound insulation effect. The sound-proof felt layer and the gypsum board are nailed on the galvanized steel plate box. The thickness of galvanized steel sheet box guarantees that the gypsum board covers girder steel joint and girder steel main part, has beautified the outward appearance effect.
Optionally, the galvanized steel sheet box is wholly filled with a fireproof rubber mud layer in the galvanized steel sheet box. The operation mode of whole packing is direct, but if the leg width of girder steel is great, the thickness of galvanized steel sheet box is corresponding great, and the whole packing of fire prevention rubber mud layer has caused the material extravagant.
Optionally, the connecting plate and the bolt are covered by the adhesion thickness of the fireproof rubber mud layer in the galvanized steel plate box, and the part, which is not filled with the fireproof rubber mud layer, in the galvanized steel plate box is filled with glass wool. When saving the material of fireproof rubber mud layer, guaranteed the syllable-dividing effect through the glass cotton.
Optionally, the galvanized steel plate box has a plate thickness of 2-5 mm.
The utility model provides a steel beam splicing gap sound insulation fireproof treatment structure, the adhesion of the fireproof rubber mud layer on the whole beam length increases the sound insulation and fireproof effects; the galvanized steel plate box prevents the aging of the fireproof rubber cement layer on one hand and serves as a fixing base of a subsequent sound-proof felt layer and a gypsum board on the other hand; the sound insulation felt layer separates the continuous hard connection among the gypsum board, the galvanized steel plate box and the steel beam, and the sound insulation effect is improved; the gypsum board covers the steel beam joint and the steel beam main body, and the appearance effect is beautified.

Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 3-4, a steel beam splicing gap sound-insulation fireproof treatment structure needs to be provided, wherein fireproof rubber cement layers 6 are adhered to two sides of the joint of a steel beam joint 2 and a steel beam main body 3 at the top of a wall body. The fireproof rubber cement layer 6 covers the steel beam joint 2 and the two sides of the steel beam main body 3 integrally. The layer of fire-retardant rubber mastic 6 is adhered over the entire length of the beam. The adhesion of the fireproof rubber cement layer 6 on the whole length of the beam increases the sound insulation and fireproof effects. The galvanized steel plate box 7 is wholly filled with the fireproof rubber cement layer 6 in the galvanized steel plate box 7. The operation mode of integral filling is direct, and the sound insulation effect is excellent.
The fireproof rubber cement layer 6 is welded on the steel beam joint 2 and the galvanized steel plate box 7 on the steel beam main body 3 to cover and wrap. The galvanized steel sheet box 7 prevents the ageing of the fire-resistant rubber cement layer 6 on the one hand and serves as a fixing base for the subsequent structure on the other hand. Fill fire prevention rubber mud layer 6 in the steel beam joint 2 and the connection gap of girder steel main part 3, 6 greasiness income gaps in fire prevention rubber mud layer, reinforcing sound insulation and fire prevention effect.
The galvanized steel plate box 7 is externally connected with a sound-proof felt layer 8, and a gypsum plate 9 is arranged outside the sound-proof felt layer 8. The sound insulation felt layer 8 separates the continuous hard connection among the gypsum board 9, the galvanized steel plate box 7 and the steel beam, and improves the sound insulation effect. The sound-proof felt layer 8 and the gypsum board 9 are nailed on the galvanized steel plate box 7. The thickness of galvanized steel sheet box 7 guarantees that gypsum board 9 covers girder steel joint 2 and girder steel main part 3, has beautified the outward appearance effect.
