Abstract
The utility model discloses a slab combination typed air duct which is characterized in that: a joint (1) is a pipe shape; the end surface of the joint is a polygon; each surface of the two ends of the joint (1) is respectively connected with a slab (2) by a bolt (5) and a nut (6); adjacent slabs (2) enclose a sealed pipe section; the air duct has convenient assembly and disassembly, solves the combination difficulty of the slab air duct, drives the development of mechanized slab production technique, thus realizing the reduction of the production cost and conveying cost; according to the prediction and calculation, the cost of the product is reduced by more than 20 percent compared with the whole cost.
Description
Technical field
The utility model relates to ventilation duct, especially relates to a kind of box-like airduct of making of the glass fibre reinforced plastics plate material of plate pack.
Background technique
Present glass fibre reinforced plastic blast pipe all is a unitary moulding, though good seal performance is bulky, from the manufacturing shop shipping to the erecting bed, transport volume is few, cost of transportation is higher, for reducing production costs and cost of transportation should adopt mechanization to produce the airduct flat board, enhances productivity, then sheet material is transported to the erecting bed, be combined into bulky airduct, this advanced person's production technology, inevitable requirement solves the technical barrier of the box-like airduct of plate pack.
The model utility content
The purpose of this utility model provides a kind of installation, convenient disassembly, transports the box-like airduct of the low plate pack of cost.
In order to achieve the above object, the utility model adopts following technological scheme: the box-like airduct of a kind of plate pack, connecting head in a tubular form, its end face is a polygonal, be connected with flat board respectively by bolt and nut on each face of connecting head two ends, adjacent panels surrounds the sealing pipeline section.
The end face of described connecting head is a quadrilateral.On the diagonal of connecting head, be welded with pull bar.The stiffening rib of connecting head intermediate portion is down " V " shape.Seam crossing in adjacent panels is welded with angle bar.Seam crossing in adjacent panels is equipped with pulling rivet.
Airduct is to connect by connecting head in the utility model, and the flat board at connecting head two ends is to be connected on the connecting head by bolt and nut, like this, installation and removal are convenient, be installed in the dull and stereotyped last formation sealed tubular on each face of connecting head, seam crossing welding angle bar between the adjacent panels and installation pulling rivet, the airduct of Xing Chenging is solid firmly like this, in addition, on the diagonal of connecting head also welding rod strengthen the stability and the soundness of airduct.
The utility model has the advantages that: the utility model is installed and convenient disassembly, solved the difficulties of combination of dull and stereotyped airduct, promoted the development that plate technique is produced in mechanization, thereby realized the reduction of cost of production, cost of transportation, reduced more than 20% than whole cost according to the measuring and calculating product cost.

Embodiment
A kind of combined type ventilation duct of making of the glass fibre reinforced plastics plate material, its structure such as Fig. 1, Fig. 2, shown in Figure 3, it is made up of connecting head 1, flat board 2, angle bar 3, cross pull bar 4 and connecting bolt 5, nut 6, pulling rivet 7, wherein connecting head 1 in a tubular form, its end face is a polygonal, be connected with flat board 2 respectively by bolt 5 and nut 6 on each face of connecting head 1 two ends, adjacent panels 2 surrounds the sealing pipeline section.Connecting head 1 can be rectangle or square, if when connecting head is quadrilateral, promptly becomes four surfaces of airduct after four airducts dull and stereotyped 2 and connecting head 1 are affixed, and seam crossing is obturaged, prevented to leak out with sealing compound between the adjacent airduct flat board 2.For strengthening the stability of connecting head 1, on the diagonal of connecting head 1, be welded with pull bar 4.Position, connecting head 1 intermediate portion is provided with stiffening rib, and stiffening rib is down " V " shape, also can be down " U " shape.Seam crossing in adjacent panels 2 is welded with angle bar 3, seam crossing in adjacent panels 2 is equipped with pulling rivet 7, promptly fastening at dull and stereotyped 2 one-tenth seamed edge places that intersect vertically of two airducts and angle bar 3 usefulness pulling rivets 7, thus realize the assembling of airduct flat board and become the airduct product that needs.Can repeat the length that above-mentioned linkage structure methods prolong airduct.
Claims (6)
