Abstract
The utility model discloses a mounting structure of a support for a large-diameter air duct, which comprises an air duct, a reinforcing ring, a concrete base and a bottom plate. A reinforcing mesh and cramp irons are disposed in the concrete base. The cramp irons are fixedly welded to the reinforcing mesh. An embedded steel plate is fixedly welded at the upper ends of the cramp irons and on the concrete base, and the bottom plate is provided with a rectangular hole corresponding to the embedded steel plate. Inner edges of the rectangular hole are welded to the embedded steel plate. A rib plate is connected between the reinforcing ring and the bottom plate. By a convenient, quick and reliable method for mounting the support for the air duct, the support can be welded after being placed and leveled, and accordingly work efficiency is high and airtightness is fine.
Description
Technical field
The utility model relates to the installing area of industrial pipeline, specifically belongs to the mounting structure of major diameter airduct bearing.
Background technology
Along with the expansion of cement factory single line production capacity, the specification of all shop lines of kiln tail is also increasing, and its diameter is usually all more than 3000mm; Highly reach tens meters; From weighing tens tons, the wind load that bears is also increasing, and the safety that the airduct bearing is installed is also more and more important.Usually airduct bearing part is made up of airduct tube wall 1, stiffening ring 2, gusset 3, base plate 4, and the installation of airduct bearing in the past mainly contains following several method:
Modal method is a reserving hole in concrete bed, in the hole, places bolt during installation, and it is in place with bearing again that bolt is passed the nut of screwing on behind the bolt hole on the base plate 4, carries out second pouring after the levelling, treat maintenance accomplish after fastening nut again.The shortcoming of this kind method is that the spacing between base plate 4 and the concrete bed is very little, and preformed hole often reaches more than the 1000mm deeply, causes vibrating head not go deep into, and concrete is not easy tamping, brings hidden danger to safety.For elimination vibrate unreal, sometimes at the scene with airduct bearing people for raising, and the concrete of second pouring arrangement of reinforcement not usually so just causes seat concrete Tai Taigao, and is neither attractive in appearance, and potential safety hazard is equally also arranged.
For eliminating above-mentioned shortcoming, the practice of bolt directly being imbedded concrete bed when the civil engineering is also arranged, pre-embedded bolt only exposes threaded portion, when the airduct bearing is installed, with bolt one by one to going into the bolt hole on the base plate 4.But because the influence of factors such as civil engineering error, concrete vibrating skew, the big bad control of machining accuracy of dust diameter, during on-the-spot the installation, the bolt hole on the base plate 4 basically can not be corresponding one by one with pre-embedded bolt, only severs base plate 4 straightened up in places.Though potential safety hazard is able to eliminate, workload is too big, useless power when useless, and installation progress also can not get guaranteeing.The third method is the upper surface pre-embedded steel slab 5 at concrete bed; Earlier that the airduct bearing is in place during installation, according to the bolt hole position on the base plate 4, on corresponding pre-embedded steel slab 5, make mark with chalk; After the airduct bearing removed; At the mark welding screw, again that the airduct bearing is in place, the nut of screwing on.This method relatively saves trouble, but also shortcoming is arranged: double-screw bolt only relies on a circle weld seam to be connected with pre-embedded steel slab 5, and weld seam is too short to cause intensity limited, therefore only is applicable to the airduct bearing that load is less.
The utility model content
The purpose of the utility model provides a kind of mounting structure of major diameter airduct bearing, and convenient, fast, reliable airduct bearing mounting method after the airduct bearing is in place, can weld through levelling, and high efficiency, tightness are good.
The technical scheme of the utility model is following:
The mounting structure of major diameter airduct bearing; Include airduct, stiffening ring, concrete bed, base plate, in concrete bed, be provided with latticed arrangement of reinforcement, dog, the fixing welding of dog and latticed arrangement of reinforcement; The upper end of dog is fixedly welded with pre-embedded steel slab on the concrete bed; Base plate and pre-embedded steel slab opposite position have rectangular opening, and rectangular opening inner edge and pre-embedded steel slab welding are connected with gusset between stiffening ring and the base plate.
Described pre-embedded steel slab can weld 4～8.
The utility model is opened rectangular opening at the upper surface pre-embedded steel slab of concrete bed on base plate, quantity is corresponding with pre-embedded steel slab with the position; The size of rectangular opening is less than the size of pre-embedded steel slab; After the airduct bearing was in place, with base plate and pre-embedded steel slab welding, the length of side of rectangular opening was the length of weld seam.Welding can be carried out second pouring after accomplishing on base plate, this step also can be omitted, and replaces with the method for brushing waterproofing materials.
The technique effect of the utility model is: after the airduct bearing is in place, can weld through levelling, high efficiency, tightness are good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, the mounting structure of major diameter airduct bearing includes airduct 1, stiffening ring 2, concrete bed 8, base plate 4; In concrete bed 8, be provided with latticed arrangement of reinforcement 7, dog 6, dog 6 and latticed arrangement of reinforcement 7 fixing welding, the upper end of dog is fixedly welded with pre-embedded steel slab 5 on the concrete bed; Base plate and pre-embedded steel slab opposite position have rectangular opening 9; Rectangular opening 9 inner edges and pre-embedded steel slab 5 welding are connected with gusset 3 between stiffening ring and the base plate, pre-embedded steel slab can weld 4～8.
Claims (2)
1. the mounting structure of major diameter airduct bearing; Include airduct, stiffening ring, concrete bed, base plate, it is characterized in that: in concrete bed, be provided with latticed arrangement of reinforcement, dog, the fixing welding of dog and latticed arrangement of reinforcement; The upper end of dog is fixedly welded with pre-embedded steel slab on the concrete bed; Base plate and pre-embedded steel slab opposite position have rectangular opening, and rectangular opening inner edge and pre-embedded steel slab welding are connected with gusset between stiffening ring and the base plate.
2. the mounting structure of major diameter airduct bearing according to claim 1 is characterized in that: described pre-embedded steel slab can weld 4～8.
