Description
Technical field
The utility model relates to fire equipment field more particularly to a kind of reinforced fireproof plates.
Background technique
In present fire protection field, usually for places such as the fire prevention of the emphasis such as market positions, such as passageway, pedestrian passage
Using fire resisting shutter, but once big fire occurs calamity, fire resisting shutter is easy to burn, and then fireproof purpose is not achieved.Then,
Board-like smoke-exhaust fire equipment is come into being.
The fire-proof plate of existing board-like fire and smoke exhaust mouth using sheet steel plate make, Fire-proof steel plate generally all than relatively thin,
Cannot be too thick, it is too heavy when not so opening, but it is too thin if, once big fire occurs, as the temperature rises, fire prevention
The intensity of steel plate can greatly decline, while be not easy to close or open smoke evacuation, operating difficulties.
Utility model content
The purpose of this utility model is that providing a kind of reinforced fireproof plate in view of the deficiencies of the prior art, intensity is high,
Easy to operate, closed is good.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions.
A kind of reinforced fireproof plate, it includes plate body and reinforcing rib, and the middle part of the plate body is provided with along its length
Groove, is welded with reinforcing rib in the groove, and the section of the groove is semicircle, the length of the both ends of the plate body along plate body
Direction is respectively arranged with the first V-shaped groove (12) and the second V-shaped groove, the opening direction phase of first V-shaped groove and the second V-shaped groove
Instead, the angle at the base angle of first V-shaped groove, the second V-shaped groove is 120 °, and first V-shaped groove, the second V-shaped groove are far from groove
Side be respectively arranged with contact portion, the contact portion is plane.
Further, the reinforcing rib is reinforcing bar.
A kind of reinforced fireproof plate of the utility model, intensity is high, and easy to operate, closed is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram in the section of the utility model；
Fig. 2 is the schematic diagram that the interconnection of the utility model uses；
In figure: 1, plate body；2, reinforcing rib；11, groove；12, the first V-shaped groove；13, the second V-shaped groove；14, contact portion.
Specific embodiment
The utility model is described further below with reference to embodiment, but is not limited to the content on specification.
As shown in the figure: a kind of reinforced fireproof plate, it includes plate body 1 and reinforcing rib 2, and the middle part of plate body 1 is square along its length
To setting fluted 11, reinforcing rib 2 is welded in groove 11, the section of groove 11 is semicircle, and reinforcing rib 2 is reinforcing bar, plate body 1
Both ends be respectively arranged with the first V-shaped groove 12 and the second V-shaped groove 13, the first V-shaped groove 12 and the 2nd V along the length direction of plate body 1
The opening direction of shape slot 13 on the contrary, the first V-shaped groove 12 and the second V-shaped groove 13 are provided with contact portion 14 far from the side of groove 11,
Contact portion 14 is plane.The angle at the base angle of the first V-shaped groove 12 and the second V-shaped groove 13 is 120 °.Angle is too small, and tension is too small,
It is unfavorable for the closure of contact portion 14, angle is too big, and V-shaped groove preparation plate body is almost in a plane, and the effect with V-shaped groove is not achieved
Fruit.
When two neighboring fire prevention plate closing, one end of two contact portions 14 is the first V-shaped groove 12, and the other end is the second V-arrangement
Slot 13, as shown, due to the opening direction of the first V-shaped groove 12 and the second V-shaped groove 13 on the contrary, in this way due to the opening and closing of V-shaped groove
The effect of power will not separate easily so that contacting closely between two contact portions 14 being in contact, simultaneously as reinforcing rib 2
It is longitudinally disposed, it on the one hand can strengthen the intensity of fire-proof plate, on the other hand plate body can be driven to rotate, control closing between plate body
It closes.
The application method of the utility model are as follows: by reinforcement welding on plate body, the both ends of reinforcing bar are then plugged on frame
On, the contact portion between adjacent two boards body is closed.The utility model, production is simple, easy to use, effect
It is good.
A kind of reinforced fireproof plate of the utility model, intensity is high, and easy to operate, closed is good.
Obviously, the above embodiment of the utility model is merely examples for clearly illustrating the present invention,
And it is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, it is stated upper
It can also be made other variations or changes in different ways on the basis of bright.Here all embodiments can not be given thoroughly
It lifts.It is all to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
Protection scope column.
