Abstract
The utility model discloses a kind of ventilation duct, comprise airduct, the junction surface of airduct caves inward and is formed with cavity, in cavity, be filled with adhesive material layer, the inserting board matching with cavity shape is connected in cavity, the width of described plate is greater than the degree of depth of cavity, and described cavity is that the degree of depth is the long strip groove of 5-100mm, and described plate is that width is the flat cuboid of 10-200mm.The utility model is set up plate by the joint between airduct and airduct, thereby strengthened the join strength between airduct, has improved the ability of antidetonation, cracking resistance, stopped potential safety hazard, and sealing effect is better.
Description
Technical field
The utility model relates to a kind of ventilation duct.
Background technique
Composite plate air pipe is the second largest kind after removing iron sheet airduct, and consumption is extensive.There are < < mechanism glass-magnesium composite plate and airduct > > national sector standard and < < mechanism glass-magnesium composite plate airduct to make and > > national building standard design atlas is installed.Mechanism glass-magnesium composite plate airduct is that to take glass magnesium fibre cloth be reinforcing material, the composite sheet that magnesium oxide, magnesium chloride or magnesium oxide, magnesium sulfate are gelatinization material is surperficial strength structure layer, be called for short magnesium gelatinous material, take polystyrene foamed boards, polyaminoresin foam plate, phenolic foam board, superfine glass plate plate, rock cotton board etc. is laminboard layer.
The installation of mechanism glass magnesium composite air duct connects, and is coating adhesive in the plane being connected with airduct at airduct, then connection airduct is close to, and under smooth condition, solidifies.This method has passed has used 10 years.Facts have proved, this junction surface serious cracking, once airduct junction surface cracking, airduct produces and leaks out, and affects drafting efficiency, is more seriously that airduct has the danger of falling, and has serious potential safety hazard.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ventilation duct is provided, and plate is set up in the joint between airduct and airduct, thereby strengthened the join strength between airduct, has improved the ability of antidetonation, cracking resistance, has stopped potential safety hazard.
The utility model technological scheme adopting of dealing with problems is:
A ventilation duct, comprises airduct, and the junction surface of airduct caves inward and is formed with cavity, is filled with adhesive material layer in cavity, and the inserting board matching with cavity shape is connected in cavity, and the width of described plate is greater than the degree of depth of cavity.
Further setting as such scheme: described cavity is that the degree of depth is the long strip groove of 5-100mm, described plate is that width is the flat cuboid of 10-200mm.
Further setting as such scheme: interconnective two airduct cavity depth sums are greater than or equal to the width of plate.
Further setting as such scheme: the difference range of interconnective two airduct cavity depth sums and plate width is 0-20mm.
Further setting as such scheme: the material of described plate is for the plate of heat insulation function or have the plate of fire-proof function.
Further setting as such scheme: described cavity is designed to upper and lower two places of airduct junction surface or two places, left and right or up and down everywhere.
Further setting as such scheme: reinforce by fastening piece between described plate and airduct.
The beneficial effects of the utility model are:
The utility model is set up plate by the joint between airduct and airduct, thereby strengthened the join strength between airduct, has improved the ability of antidetonation, cracking resistance, stopped potential safety hazard, and sealing effect is better.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment
1, make in advance the plate 2 connecting for airduct 1, as shown in Figure 1, the length of plate 2, thickness and length, the thickness of the airduct that inserts 1 cavity 4 supporting, the width of plate 2 is 10mm-200mm, during connection, as shown in Figure 3, each minute, inserted in the laminboard layer of two airducts 1 that are connected half left and right, and the material of plate 2 divides two classes, and a class is the plate with heat insulation function, there is thermal conductivity low, the advantages such as high insulating effect; Another kind of is fireproof plate.
2, as shown in Figure 2, the junction surface 3 at airduct 1 with airduct 1, scrapes off the about 5-100mm blast pipe board of degree of depth laminboard layer, forms cavity 4.
3, at the appropriate adhesive of the interior filling of cavity 4, plate 2 inserts after cavity 4, by plate 2 extruding adhesive, fills up cavity 4, makes plate 2 and airduct cavity 4 bonding firmly.
4, as shown in Figure 4, when airduct 1 docks with airduct 1, the plate 2 that is exposed at airduct 1 outside is inserted in the cavity 4 of corresponding airduct 1, remove the adhesive that is expressed to outside, under smooth condition, solidify.
5, as shown in Figure 5, available fastening piece 5 (nailing, screw etc.) is reinforced plate 2, also can.
6, connect can be only between the upper and lower plates or left and right plate two plates of airduct 1 for plate 2, or plate four plates adopt simultaneously up and down.
