Abstract
The utility model discloses a fire-proof accessory for a cable tray, which comprises a tray trough housing, wherein the tray trough housing is filled with a refractory material and comprises a first half body and a second half body that are arranged in a right and left staggered manner; and the first half body and the second half body are provided with identical vertical telescoping mechanisms. As the fire-proof accessory for the cable tray adopts a right and left staggered arrangement structure and the vertical telescoping mechanisms, cable holes are tightly braced through adjustment according to vertical and horizontal dimensions, so that a lot of fire-proof and plugging materials and high workload are saved, and the fire-proof and plugging efficiency is improved. The fire-proof accessory for the cable tray can be improved based upon the original cable tray structure, and therefore, has the benefits of convenience in production and quickness in operation.
Description
Technical field
The utility model relates to the power construction technical field, relates in particular to a kind of fire prevention annex that is used for cable testing bridge.
Background technique
According to the code requirement of power industry, built on stilts cable testing bridge need be done the fireproof blocking measure at through walls or through-flooring place.Conventional way is, in cable hole, cable hole, adopting does not have (having) machine fire prevention calking, 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 big.Secondly, fire-proof sealing material requirements such as fire prevention calking, coating, dividing plate are also big, and this just causes the waste of material, and this drawback is just more outstanding in the generation engineering of big 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.
The model utility content
Because the above-mentioned defective of existing technology, the utility model technical problem to be solved provides a kind of economical with materials, the annex of cable testing bridge fire prevention easily of constructing.
For realizing above-mentioned purpose, the utility model provides a kind of cable testing bridge fire prevention annex, comprises the crane span structure pot shell, is filled with refractory material in the said crane span structure pot shell; First halfbody that shifts to install about said crane span structure pot shell comprises, second halfbody; Said first halfbody, said second halfbody have identical extending means up and down respectively.
Preferably, said crane span structure pot shell is a refractory material.
The beneficial effect of the utility model is:
The cable testing bridge fire prevention annex of the utility model; Owing to shift 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 save a large amount of fire-proof sealing materials, and practiced thrift the hard work amount, improved the fireproof blocking working efficiency.The cable testing bridge fire prevention annex of the utility model can improve on original cable testing bridge structure, therefore also has beneficial effect convenient for production, swift to operate.
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.
Description of drawings
Fig. 1 is an embodiment's of the utility model a sectional structure schematic representation.
Fig. 2 is the structural representation of A-A portion among Fig. 1.
Embodiment
As shown in Figure 1, cable testing bridge fire prevention annex one specific embodiment of the utility model 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 first halfbody 21, second halfbody 22 that shifts to install.Particularly, in the present embodiment, first halfbody 21 is a half-frame structure, and opening is greater than the opening of second halfbody 22.
As shown in Figure 2, first halfbody 21, second halfbody 22 are arranged at intervals with some mounting holes 25 respectively at its end face.Through adjustment, can change the degree of depth that first halfbody 21, second halfbody 22 insert relatively, 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 wall of first halfbody, 21 vertical directions is provided with 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, are made up of the 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.
The cable testing bridge of the utility model fire prevention annex matches with the model of normal cable crane span structure, its connection part press the connection of normal cable crane span structure just can, and just can confirm 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, practices thrift a large amount of fire-proof sealing materials.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
Claims (2)
1. a cable testing bridge fire prevention annex comprises the crane span structure pot shell, is filled with refractory material in the said crane span structure pot shell; It is characterized in that: first halfbody that shifts to install about said crane span structure pot shell comprises, second halfbody; Said first halfbody, said second halfbody have identical extending means up and down respectively.
2. cable testing bridge fire prevention annex as claimed in claim 1, it is characterized in that: said crane span structure pot shell is a refractory material.
