Description

Composite board for smoke-proof pipeline

Technical Field

The utility model relates to a composite sheet technical field, concretely relates to prevent composite sheet for exhaust pipe.

Background

The composite board for the smoke exhaust preventing pipeline mainly takes low-alkalinity cement as a base material, has the characteristics of high strength, good toughness, fire prevention, heat insulation, convenient construction and the like, and is widely applied to rooms, households, toilets, kitchens, communication pipes and the like of high-rise frame buildings;

the existing composite board for the smoke exhaust prevention pipeline is covered with a layer of fireproof shell in the practical production process, but the composite board for the smoke exhaust prevention pipeline is usually formed by pouring in the practical production process, a pouring mould is often needed to be used, the composite board is taken down from the mould after forming, then the fireproof shell is covered, the steps are complex, and the practical production is not convenient.

Therefore, there is a need for a composite panel for smoke exhaust preventing ducts to overcome the above problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the embodiment of the utility model provides a prevent composite sheet for exhaust pipe has realized the purpose of solving the problem that proposes in the background art.

The embodiment of the utility model provides a in order to realize above-mentioned purpose, specifically adopt following technical scheme: the utility model provides a prevent composite sheet for exhaust pipe, includes first casing, the inside of first casing forms square ware chamber, the inside in square ware chamber is provided with the composite sheet main part, the outside lock of first casing has the second casing.

As a further improvement of the above technical solution:

the inner wall of the first shell is provided with a hemispherical bulge located inside the square dish cavity.

The protruding inside of hemisphere forms the draw-in groove, be provided with the arc arch of joint in the draw-in groove inside on the inner wall of second casing.

And a cavity positioned at the side part of the composite board main body is arranged in the second shell.

The utility model discloses beneficial effect does:

when the composite board is actually used, the composite board base material for the smoke-discharge preventing pipeline is directly poured into the square vessel cavity in the first shell, so that the composite board for the smoke-discharge preventing pipeline is directly formed in the first shell, the processes of removing a mould and covering a fireproof shell are omitted, the steps required by production are reduced, and the actual production is facilitated;

when the composite board for the smoke exhaust prevention pipeline is formed in the first shell in actual use, the hemispherical bulges are clamped into the side parts of the composite board for the smoke exhaust prevention pipeline, so that the composite board for the smoke exhaust prevention pipeline is connected with the first shell more firmly, namely the first shell is arranged on the composite board for the smoke exhaust prevention pipeline more stably;

when the fixing device is actually used, the arc-shaped bulges are clamped into the clamping grooves, so that the second shell can be fixed outside the first shell through the arc-shaped bulges, and the fixing bolts can be driven into countersunk grooves formed in the arc-shaped bulges to prevent the fixing bolts from protruding out of the side parts of the second shell;

when in actual use, the one side that is equipped with the cavity with the second casing sets up in meeting fire department for reduce the heat of transmission to in the composite sheet main part through the cavity, promote holistic fire proofness.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1 to 4, the embodiment of the utility model discloses a composite board for smoke exhaust prevention pipeline, which comprises a first shell 1, wherein a square vessel cavity 3 is formed inside the first shell 1, a composite board main body 4 is arranged inside the square vessel cavity 3, and a second shell 2 is buckled outside the first shell 1;

when in actual use, directly will prevent that the composite sheet base material for the exhaust pipe pours in the square ware chamber 3 of first casing 1 inside for prevent that the composite sheet direct forming for the exhaust pipe is in the inside of first casing 1, save the process of demolising the mould and cover and establish the fire prevention shell, reduce the required step of production, the actual production of being convenient for.

As further illustration of the present application: a hemispherical bulge 5 positioned inside the square dish cavity 3 is arranged on the inner wall of the first shell 1; when in actual use, prevent that the composite sheet shaping for the flue gas discharging pipe is in the inside of first casing 1, the protruding 5 card of hemisphere goes into the lateral part of preventing the composite sheet for the flue gas discharging pipe for prevent that the connection between composite sheet for the flue gas discharging pipe and first casing 1 is more fastened, even make 1 more stable setting of first casing prevent on the composite sheet for the flue gas discharging pipe.

As further illustration of the present application: a clamping groove 6 is formed in the hemispherical protrusion 5, an arc protrusion 7 clamped in the clamping groove 6 is arranged on the inner wall of the second shell 2, and when the fixing device is in actual use, the arc protrusion 7 is clamped in the clamping groove 6, so that the second shell 2 can be fixed on the outer portion of the first shell 1 through the arc protrusion 7, and a fixing bolt can be driven into a countersunk groove formed in the arc protrusion 7, so that the fixing bolt is prevented from protruding out of the side portion of the second shell 2;

first casing 1 and second casing 2 are the metal material, and hemisphere arch 5 and arc arch 7 also are the metal material, and it can take place the deformation volume of certain degree, and allow to have certain error when machining for there is tiny gap between first casing 1 and the second casing 2, therefore the inside of draw-in groove 6 can be gone into to the protruding 7 card of arc.
