Abstract
The utility model relates to a glass fibre reinforced plastic rectangle air duct, which is in latch board connection. The connecting part between the rectangle air ducts is connected by an inner latch board and an outer latch board. The inner latch board is L-shaped mould board with one side having teeth. The outer latch board is two groove-shaped horizontal outer latch boards and two groove-shaped vertical outer latch boards. The utility model saves both the flange drilling hole and the bolt for installation, and enhances the installation speed, and decreases the installation cost greatly. Compared with the prior method of flange installation, the utility model saves the interior space of the building. Without using the internal model forming, the manufacture of the insulated air duct of the utility model saves a large amount of dies and site, and the rapid field manufacture and production become possible.
Description
The utility model relates to a kind of heating ventilation and air-conditioning engineering equipment, the glass fibre reinforced plastics rectangular air duct that a kind of specifically novel holding plate type connects.
At present, glass fibre reinforced plastic blast pipe all uses mould-forming, and template is made of plank or sheet metal, and rectangular air duct is shaped and uses internal mold, and internal mold is dismountable hollow-core construction, adopts manual coating process moulding.During operation, wrap earlier the cellophane of layer of transparent on the surface of internal mold, and the resin that mixed up of full coat outside, apply one deck glass cloth again.Whenever be coated with one deck resin and just apply one deck, flange should be carried out with mould in advance, puts in the process of application of resin, together pastes whole with airduct.Whole joint airduct is through after a while curing, and reaching can the demoulding after the certain intensity.The heat preserving fiberglass airduct is made interlayer with tube wall exactly, and the sandwich material in the interlayer can adopt fire retardant polystyrene, fire-retardant polyester foam etc.This airduct is not easy to process at the scene, and cost of transportation is higher; And this airduct adopts flange to install, and installation cost is higher, but also has taken the architecture indoor space too much.
The purpose of this utility model is to provide a kind of and can on-the-spot processes, and need not install by flange, and a kind of novel holding plate type that reduces installation cost connects the glass fibre reinforced plastics rectangular air duct.
The utility model purpose realizes in the following manner: the glass fibre reinforced plastics rectangular air duct that a kind of holding plate type connects, and airduct is glass fibre reinforced plastic blast pipe or glass fibre reinforced plastics thermal insulation wind pipe; The glass fibre reinforced plastics thermal insulation wind pipe is made up of glass fibre reinforced plastics inwall, glass fibre reinforced plastics outer wall and the adiabator layer that is clipped between inside and outside wall, described glass fibre reinforced plastics inwall is made up of glass fibre cloth and resin, and rectangular air duct is connected with horizontal outer card plate and vertical outer card plate by interior clamp with the rectangular air duct connecting end; Interior clamp is the L type template of a side band tooth limit shape bail; Horizontal outer card plate is flute profile with vertical outer card plate, and there are two bails at vertical outer card plate two ends, and then there is the corresponding hole clipping of bail with vertical outer card plate two ends at horizontal outer card plate two ends; Also have respectively and the corresponding fixed hole of interior clamp bail on horizontal outer card plate and the vertical outer card plate, interior clamp other parts except that bail are embedded in the airduct, horizontal outer card plate is detained mutually with vertical outer card plate, and promptly the bail at vertical outer card plate two ends is stuck in the hole clipping of horizontal outer card plate; The bail of interior clamp is stuck in the fixed hole of horizontal outer card plate and vertical outer card plate.
These glass fibre cloth both sides are tenon shape, and thermal insulation layer four angle joint places are 45 ° of oblique angles, and place, four oblique angles all has frp layer to connect the inside and outside wall of glass fibre reinforced plastics.
The utility model has the advantages that: 1, making method need not in mold forming, can save a large amount of moulds and place, make on-the-spot production fast of glass fibre reinforced plastic blast pipe that feasibility arranged.2, the board-like connection exquisite composition of metal card has been saved flange drilling and two on bolt of installation, and has been improved installation rate, and making at present, higher mounting cost descends significantly.3, outer card plate protrudes airduct apart from having only 10mm, compares with existing flange installation way, has saved the architecture indoor space.
The utility model content is described in detail in detail with reference to the accompanying drawings.
