Abstract
The invention discloses a cable bridge fireproof accessory which comprises a bridge groove casing, wherein fire-resisting materials are filled in the bridge groove casing. The bridge groove casing comprises a first half body and a second half body, and the first half body and the second half body are arranged in left-and-right dislocation mode and are respectively provided with vertical stretchable mechanisms which are identical to each other. The left-and-right dislocated structure and the vertical stretchable mechanisms are adopted, a cable hole and a cable cavity are both tensioned tightly through vertical and lateral size adjustment, accordingly a large quantity of fireproof plugging materials are saved, heavy work load is reduced, and fireproof plugging working efficiency is improved. The cable bridge fireproof accessory can be improved on the basis of the existing cable bridge structure, and accordingly has the beneficial effect of being convenient to produce and fast and convenient to operate.
Description
Technical field
The present invention relates to the power construction technical field, relate in particular to a kind of fire prevention annex for cable testing bridge.
Background technique
According to the code requirement of power industry, built on stilts cable testing bridge need to be done the fireproof blocking measure at through walls or through-flooring place.Conventional way is, adopts without (having) machine fire prevention calking in cable hole, cable hole, and fire bulkhead or back-fire relief bag carry out shutoff.Because the quantity in cable hole, cable hole is various in each engineering, so the workload of the fireproof blocking in later stage construction is quite large.Secondly, the fire-proof sealing material requirements such as fire prevention calking, coating, dividing plate are also large, and this just causes the waste of material, and this drawback is just more outstanding in the generation engineering of large unit.
Therefore, those skilled in the art be devoted to develop a kind of economical with materials, the cable testing bridge fire prevention annex of constructing easily.
Summary of the invention
Because the defects of prior art, technical problem to be solved by this invention provides a kind of economical with materials, the easily cable testing bridge fire prevention annex of constructing.
For achieving the above object, the invention provides a kind of cable testing bridge fire prevention annex, comprise the crane span structure pot shell, be filled with refractory material in the described crane span structure pot shell; The first halfbody that shifts to install about described crane span structure pot shell comprises, the second halfbody; Described the first halfbody, described the second halfbody have respectively identical up and down extending means.
Preferably, described crane span structure pot shell is refractory material.
The invention has the beneficial effects as follows:
Cable testing bridge fire prevention annex of the present invention, owing to shifting to install structure and extending means up and down about having adopted, according to about passing through, about size adjusting with cable hole, cable hole " support " tight, not only saved a large amount of fire-proof sealing materials, and saved the hard work amount, improved the fireproof blocking working efficiency.Cable testing bridge fire prevention annex of the present invention can be improved on original cable testing bridge structure, therefore also has beneficial effect convenient for production, swift to operate.
Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand fully purpose of the present invention, feature and effect.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of one embodiment of the invention.
Fig. 2 is the structural representation of A-A section among Fig. 1.
Embodiment
As shown in Figure 1, cable testing bridge fire prevention annex one specific embodiment of the present invention comprises the crane span structure pot shell 2 that is arranged in the cable hole (hole) 1, is filled with refractory material 3 in the crane span structure pot shell 2, forms a passage 4, is used for cable and wears wherein.
Crane span structure pot shell 2 comprises left and right the first halfbody 21 that shifts to install, the second halfbody 22.Particularly, in the present embodiment, the first halfbody 21 is half-frame structure, and opening is greater than the opening of the second halfbody 22.
As shown in Figure 2, the first halfbody 21, the second halfbody 22 are arranged at intervals with respectively some mounting holes 25 at its end face.By adjusting, can change the relatively degree of depth of insertion of the first halfbody 21, the second halfbody 22, thereby regulate the size of cable testing bridge fire prevention annex on left and right direction, to be full of cable hole (hole) 1.
The first halfbody 21 is provided with at the wall of vertical direction that extending means 23, the second halfbodies 22 also have extending means 24 about in the of about in the of one.Extending means 23,24 has identical structure up and down.
Particularly, extending means 23,24 up and down is comprised of sidewall and the locating stud of two sections inside and outside containings, can regulate height, thereby regulate the size that cable testing bridge fire prevention annex makes progress at upper and lower, to be full of cable hole (hole) 1.
Cable testing bridge of the present invention fire prevention annex matches with the model of normal cable crane span structure, its connection part routinely cable testing bridge just connect can, and just can determine the size in cable hole, hole according to the prevent fires model of annex of cable testing bridge.This cable testing bridge fire prevention annex, purposes is very extensive in sending out project of transmitting and converting electricity, and it is all very convenient to construct, transform, overhaul, and is of value to the standardization of fireproof blocking in the engineering, improves construction quality and efficient, saves a large amount of fire-proof sealing materials.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all in the art technician all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
