Abstract

The present invention relates to a method for making and connecting ventilation pipelines using foam sandwich incombustible boards as substrates. The method comprises two parts, which are the assembly and the bonding connection of the ventilation pipelines and the dislocation connection of assembled and bonded ventilation pipelines. The assembly and the bonding connection of the ventilation pipelines comprise the steps that the assembly positions of the foam sandwich incombustible boards are designed into right angle step-shaped structures, and bonding surfaces of which the thickness are equivalent to two times of the thickness of the foam sandwich incombustible boards to obtain maximum bonding strength. The connection of the assembled ventilation pipelines adopts a mode of the dislocation connection of upper panels, lower panels, left panels and right panels of the ventilation pipelines. Thereby, the present invention omits metal fasteners, reduces cost, brings convenience to site operation and greatly improves installation efficiency.

Description

A kind of ventilation duct is made, connecting means
One, technical field
The present invention relates to a kind of is ventilation duct making, the connecting means of substrate with the Foam Core Non-sparking Board, belongs to building material technical field.
Two, background technique
At present, at factory building, hotel, market, a large amount of glass fibre magnesia oxychloride cement ventilation ducts that use of underground engineering, general employing integral forming technique is made, and the ventilation duct that adopts this integral forming process to make needs the specific requirement of elder generation according to the airduct that will make usually, make the mould tire with timber in advance, on the mould tire, make airduct then, slough the mould tire after waiting to solidify, just can obtain the airduct finished product, and the connection between the airduct then adopts flanged metal fastenings to connect.This traditional ventilation duct is made, connecting means, not only need to expend the timber of a large amount of preciousnesses, and cost is very high, and the efficient of field operation is also very low.
Three, summary of the invention
In view of the problem that above-mentioned prior art exists, the object of the present invention is to provide a kind of is ventilation duct making, the connecting means of substrate with the Foam Core Non-sparking Board.
The objective of the invention is to realize in the following way:
This ventilation duct is made, connecting means comprises that adopting Foam Core Non-sparking Board is the ventilation duct assembly unit, bonding of substrate, and with the connection two large divisions of assembly unit, bonding ventilation duct, wherein: the upper and lower panel and the left/right panel of Foam Core Non-sparking Board having been tailored ventilation duct respectively; In upper and lower panel and left and right sides panel, it is stepped that wherein the assembly unit position of a panel is designed to the right angle, the another kind of panel assembly unit position of assembly unit is the flat degree of lip-rounding in right angle with it, be coated with at the assembly unit position of rectangular stair-stepping two panels then and be covered with binder, formation is equivalent to the bonding plane of twice Foam Core Non-sparking Board thickness, and will be with it the phase assembly unit two flat degree of lip-rounding panels in right angle are mutually bonding with it in addition the time, with upper and lower panel and left and right sides panel at the length direction setpoint distance that misplaces.
Connection between the good ventilation duct of described assembly unit is the Placement that adopts ventilation duct upper and lower panel and left and right sides panel to misplace.
The present invention compared with prior art has following advantage:
Owing to adopted the bonding plane of twice Foam Core Non-sparking Board thickness, increased bonding strength greatly, and the connection between the good ventilation duct of assembly unit, then adopt the Placement of ventilation duct upper and lower panel and left and right sides panel dislocation, thereby not only save metal fastenings, reduced cost, and convenient site operation, and improved installation efficiency greatly.
Four, description of drawings

Fig. 2 is the structural representation that adopts the ventilation duct connection part of dislocation connection
Fig. 3 is the ventilation duct structural representation that adopts dislocation to connect
In the drawings: the 1-surface layer; The 2-foam layer
Five, embodiment
Embodiment 1: the assembly unit of ventilation duct, making
With the requirement of Foam Core Non-sparking Board by the specification of ventilation duct, the upper and lower panel and the left/right panel of ventilation duct have been tailored respectively, in upper and lower panel and left and right sides panel, it is stepped that wherein the assembly unit position of a panel is designed to the right angle, the another kind of panel assembly unit position of assembly unit is the flat degree of lip-rounding in right angle with it, be coated with at the assembly unit position of rectangular stair-stepping two panels then and be covered with binder, form the bonding plane (Fig. 1) that is equivalent to twice Foam Core Non-sparking Board thickness.And will be with it the phase assembly unit two flat degree of lip-rounding panels in right angle are mutually bonding with it in addition the time, with upper and lower panel and left and right sides panel at the length direction setpoint distance (Fig. 2) that misplaces.
Embodiment 2: the connection of the ventilation duct after the assembly unit
The dislocation connection part of the ventilation duct that assembly unit is good is coated binder (accompanying drawing 3), and two ventilation ducts that are connected are inserted the dislocation position, is close to curing then, has so promptly finished the connection of ventilation duct.
This connects technology easy construction, bonding strength height, low, the good airproof performance of cost, does not have flange, and is easy for installation.

Claims (2)

1, a kind of ventilation duct making, connecting means, comprise that adopting Foam Core Non-sparking Board is the ventilation duct assembly unit, bonding of substrate, and, it is characterized in that: the upper and lower panel and the left/right panel of Foam Core Non-sparking Board having been tailored ventilation duct respectively the connection two large divisions of assembly unit, bonding ventilation duct; In upper and lower panel and left and right sides panel, it is stepped that wherein the assembly unit position of a panel is designed to the right angle, the another kind of panel assembly unit position of assembly unit is the flat degree of lip-rounding in right angle with it, be coated with at the assembly unit position of rectangular stair-stepping two panels then and be covered with binder, formation is equivalent to the bonding plane of twice Foam Core Non-sparking Board thickness, and will be with it the phase assembly unit two flat degree of lip-rounding panels in right angle are mutually bonding with it in addition the time, with upper and lower panel and left and right sides panel at the length direction setpoint distance that misplaces.
2, ventilation duct according to claim 1 make, connecting means, it is characterized in that: the connection between the good ventilation duct of described assembly unit is the Placement that adopts ventilation duct upper and lower panel and left and right sides panel to misplace.
