Abstract
The utility model relates to a fireproof blocking structure at a cable bridge floor-crossing plate. The fireproof blocking structure includes that a water retaining platform is constructed around a floor hole (if the floor hole is close to a wall in position, the water retaining platform is constructed along three sides, not close to the wall, of the hole), fireproof rock wool or fireproof plaster is tightly filled in a gap between the water retaining platform and a bridge, space in the bridge is filled by a fireproof bag, two sides of the hole of a floor are sealed tightly by fireproof plates or steel plates, the fireproof plates should be tailored and spliced regularly, and space around the fireproof plates, the junctions of the fireproof plates and the bridge and pieced positions of the fireproof plates are caulked flatly and smoothly by the fireproof plaster. By adopting the structure, the water retaining platform is constructed around the bridge, so that better water retaining effect can be realized; the distance between the bridge and space around the hole is determined, so that more convenience is brought to blocking and more economic benefit can be acquired; the hole and the gap are both blocked and sealed by fireproof materials, and fireproofing and blocking effect is further realized; and the fireproof plates are orderly and attractive in splicing, so that appearance on two sides of the floor are more attractive.
Description
Technical field
The utility model relates to construction engineering technical field, relates in particular in the building construction process a kind of cable testing bridge and crosses floor place fireproof blocking structure.
Background technique
Fireproof blocking passes body of wall with the fire-proof sealing material hermetically-sealed cable exactly or floor forms hole, and its effect is to prevent that fire spread from having arrived source of goods adjacent areas, reaches the purpose of protection personnel and device security.The common method for blocking in job site is only to have carried out shutoff or done fireproof blocking but the shutoff imprecision with cement mortar in the outside of crane span structure, bright phenomenon is arranged, and filling is not done in the inside to crane span structure, the fireproof blocking way is not considered waterproof problem around the crane span structure that also has, and these ways all will influence outward appearance, function of use and safety.
Summary of the invention
At the deficiency that prior art exists, the technical problem that the utility model solves provides a kind of cable testing bridge reliable and secure, attractive in appearance and crosses floor place fireproof blocking structure.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cable testing bridge is crossed floor place fireproof blocking structure and is comprised around floor hole and build the dash platform by laying bricks or stones, can adopt fire prevention rock wool or fire prevention clay sealing filling in the space between dash platform and the crane span structure, the space can adopt the fire prevention bag to fill in the crane span structure, the hole both sides of floor use cutting splicing regular fireproof plate or steel plate capping tight, and fireproof plate periphery, fireproof plate and crane span structure intersection, fireproof plate edge joint position can use the fire prevention clay to carry out smooth, smooth filleting.
Space around above-mentioned crane span structure and the floor hole is 50mm.
Above-mentioned dash platform is 50mm apart from the hole edge distance, and dash platform height is 50mm
Above-mentioned fireproof plate is wider than hole 100mm, and fire prevention clay width is 10mm.
After adopting such structure, owing to around crane span structure, build the dash platform, can effectively play waterproof action; Edge joint position at dash platform, crane span structure, hole both sides, fireproof plate all adopts fire proofing material filling, shutoff, has really played the effect of fireproof blocking; Fireproof plate cuts Founder, and the fire prevention clay is smooth, smooth, makes the impression of shutoff place better again.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1, fire prevention clay 2, dash platform 3, floor hole 4, fire prevention bag 5, fireproof plate 6, cable 7, fixing bolt.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details.
As shown in Figure 1, crane span structure with 300 * 200 is example, stay the space of 50mm around floor hole and the crane span structure, build the dash platform apart from hole 50mm, the wide 100mm of dash platform, high 50mm, filling fire prevention rock wool in the space between dash platform and the crane span structure, space in the crane span structure adopts the fire prevention bag to fill, the fireproof plate capping of floor both sides, fireproof plate is than the wide 50mm in hole, then, with the fireproof plate fixation, the slit between the slit between the slit between fireproof plate and the body of wall, fireproof plate and the crane span structure, the piece of fireproof plate is with the fire prevention clay filleting of wide 10mm with EXPANSION ANCHOR BOLTS.
After adopting such structure, owing to around crane span structure, build the dash platform, can effectively play waterproof action; Edge joint position at dash platform, crane span structure, hole both sides, fireproof plate all adopts fire proofing material filling, shutoff, has really played the effect of fireproof blocking; Fireproof plate cuts Founder, and the fire prevention clay is smooth, smooth, makes the impression of shutoff place better again.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
