Abstract
The utility model discloses a dull and stereotyped pin-connected panel exhaust passage, including four panels of calcium silicate material, adjacent panel splices into the exhaust passage that the cross-section is the rectangle through tenon and the mortise that set up on it. The utility model discloses choose for use calcium silicate's panel as the main material of exhaust passage or air pipe, the anti bending property of full play calcium silicate board resistance to compression, simultaneously abundant again utilize its superior fire prevention, waterproof and heat retaining good performance, make the product satisfy each item index that national standard JG/T194 + 2006 "house kitchen, bathroom exhaust passage" required completely. And the weight is light, the strength is high, and the installation is convenient.
Description
Technical Field
The utility model relates to a building technical field, concretely relates to a ventiduct that is arranged in kitchen, bathroom exhaust passage and house among the housing construction.
Background
At present, cement mortar is adopted as a main material and a wire mesh is adopted as a reinforcing material in national standard JG/T194-plus 2006 exhaust passage of residential kitchens and toilets. If the thickness of the product designed according to the standard is required to meet the performance required by the standard design, the performance can not be achieved basically, and particularly, the two indexes of the fire resistance limit and the flexibility resistance are strictly checked according to the national standard, so that a qualified product can not be obtained. Therefore, the method comprises the following steps: many alternatives to materials are available on the market, but the results are not very desirable. At present, in general, the assembled or assembled flue is made of a glass magnesium plate as a main material, is cut into four blocks with the same length as a required pipe body, is assembled by using a shooting nail, and is coated and formed by using a cementing material. There are also lining frames for the inside. However, the main material is a glass magnesium plate, and the material is characterized by containing a large amount of chloride ions, so that the metal gun needle is corroded by the chloride ions and then decayed. In addition, the stability of the material is not good enough, the glass magnesium board can absorb moisture in the air to generate the phenomena of halogen return and moisture return in the using process, then the glass magnesium board loses the strength of the glass magnesium board, and simultaneously deforms to generate the cracking of the pipe body. The service life of the product can not be as long as that of the traditional building taking cement as a main material.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide a dull and stereotyped pin-connected panel exhaust passage especially chooses for use high-quality calcium silicate board, the required size of fibre reinforcing cement board cutting into the product, cuts into the shape in tenon and fourth of the twelve earthly branches respectively at two edges and splices into exhaust passage, air pipe of rectangle, does not ask at the veneer to apply paint sticky material with a brush, makes it have the performance that the product etalon has.
The utility model discloses a following technical scheme realizes:
the flat plate assembled exhaust passage is characterized by comprising four plates made of calcium silicate materials, and the adjacent plates are spliced into the exhaust passage with the rectangular cross section through tenons and mortises arranged on the adjacent plates.
The flat plate assembled exhaust passage is characterized in that the plate is a flat plate, and a plurality of tenons and mortises which are arranged in sequence are respectively cut on two sides of the long edge of the flat plate.
The flat plate assembled exhaust passage is characterized in that four splicing corners are formed when four plates are spliced, and four splicing seams are bonded at the four splicing corners by using an adhesive layer.
The flat plate assembled exhaust passage is characterized in that an R-shaped semi-circular angle or a right angle is formed at the position of an internal corner formed by the splicing corners by using inorganic polymer.
The flat plate assembled exhaust passage is characterized in that a supporting piece with a triangular or rectangular strip structure is bonded at the position of an internal corner formed by the splicing corners.
The utility model discloses choose for use calcium silicate's panel as the main material of exhaust passage or air pipe, the anti bending property of full play calcium silicate board resistance to compression, simultaneously abundant again utilize its superior fire prevention, waterproof and heat retaining good performance, make the product satisfy each item index that national standard JG/T194 + 2006 "house kitchen, bathroom exhaust passage" required completely. And the weight is light, the strength is high, and the installation is convenient.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings, and specific embodiments are given.
As shown in figures 1-2, the plate-assembled exhaust passage of the present invention comprises four plates made of calcium silicate, and the adjacent plates are spliced into an exhaust passage with a rectangular cross section by tenons and mortises arranged thereon. Specifically, the plate is made of flat plates, and a plurality of tenons and mortises which are arranged in sequence are cut on two sides of the long edge of each flat plate respectively. When four flat shifts are spliced in sequence, four splicing corners are formed, and four splicing seams are bonded at the four splicing corners by using adhesive layers. In order to improve the integral stability of the product, an R-shaped semi-fillet or a right angle is formed at the position of an internal corner formed by the splicing corners by using inorganic polymer or a supporting piece with a triangular or rectangular strip-shaped structure is bonded at the position of the internal corner formed by the splicing corners.
The utility model discloses a calcium silicate board, cement fiberboard are as the main material of body for assemble exhaust passage, pipeline and splice into required product if the backplate, products such as piping shaft, according to required pipeline of assembling and the size of required product arbitrary length when cutting into pipeline length or not enough length, cut into the size of terminal surface width simultaneously. And then, cutting structures of tenons and mortises on two sides of the long edge of the plate by special machinery or manually to splice the four flat plates into a rectangle, bonding the four splicing seams by using an adhesive, and then hooking R-shaped semi-circular corners or right angles at internal corners by using inorganic polymers to increase the strength of the internal corners and the overall stability of the member. Or a triangular or rectangular strip is bonded at each internal corner to increase the stability of the member.
