Abstract
The utility model relates to an irregular shaped steel formwork for chimney pouring, which comprises a bottom plate, side plates and ribbed plates. Clamping holes are arranged on the side plates and the ribbed plates. The bottom plate is of the shape of a right-angle trapezoid. The length of an upper side plate of one irregular shaped steel formwork is equal to the length of a lower side plate of an upper irregular shaped steel formwork adjacent to the irregular shaped steel formwork. The length of a lower side plate of one irregular shaped steel formwork is equal to the length of the length of an upper side plate of a lower irregular shaped steel formwork adjacent to the irregular shaped steel formwork. Two adjacent formworks are abutted through the clamping holes on the side plates by using U-shaped clamps. When a conical part with a gradually changing cross section of a chimney is contracted, an intact platform without a staggered platform is formed and therefore the external surface of the chimney is tidy and attractive.
Description
Technical field
The utility model relates to a kind of steel form of chimney, is specifically related to a kind of Special-shaped Steel Formwork that chimney is built that is used for.
Background technology
The design of large-scale chimney all must be designed to have the cylindrical shape of certain taper to it, in building of chimney wall will produce the chimney wall in the process conical gradual change cross section.Contracture method to the conical gradual change of chimney wall cross section in the prior art mainly adopts the overlap joint steel form to carry out contracture.Because the inside and outside template of existing chimney all is designed to the block structure of the rectangle of uniform specification, because chimney is conical, in each circle building process, contracture place steel form must overlap to adapt to the conical gradual change cross section of chimney.This overlapping mode contracture can cause many places faulting of slab ends (>=3 ㎜) phenomenon of chimney external surface when placing of concrete, influenced the outward appearance of chimney wall, has strengthened the workload of repairing simultaneously.
The utility model content
The purpose of the utility model be to provide a kind of do not have faulting of slab ends phenomenon, outward appearance neat be used for the Special-shaped Steel Formwork that chimney is built.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind ofly be used for the Special-shaped Steel Formwork that chimney is built; Comprise base plate, side plate and floor, side plate is made up of the four blocks of upper and lower, left and right side plates in the periphery that is fixed in base plate, and floor is arranged on the base plate; Have hole clipping on side plate and the floor, described base plate is a right-angled trapezium.
Technique scheme is done further improvement, and the epipleural length of Special-shaped Steel Formwork is the lower side panel length of Special-shaped Steel Formwork adjacent above it, and lower side panel length is the epipleural length of Special-shaped Steel Formwork adjacent below it.
And two between the adjacent forms to be that hole clipping through side plate sticks into the row butt joint with U-shaped fixing.
The utility model designs the length of the upper and lower side plate of this trapezoidal steel form according to the size of the scale of chimney and the contracture gradient.
After adopting this trapezoidal steel form; When the conical gradual change section contracture of chimney; Utilize the short characteristics of the long end of this trapezoidal steel form one end, carry out having formed the complete platform of no faulting of slab ends near docking with the standard steel template of the right and left; Behind the placing of concrete, the external surface of chimney is just very neat, attractive in appearance like this.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify.
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is an A place partial enlarged drawing among Fig. 1;
Fig. 4 is the vertical butt joint sketch map of the utility model.
Among the figure: 1-base plate 2-floor 3-side plate 4-hole clipping 5-Special-shaped Steel Formwork
The specific embodiment
A kind of Special-shaped Steel Formwork that chimney is built that is used for shown in Figure 1; Comprise base plate 1, side plate 3 and floor 2, side plate 3 is made up of the four blocks of upper and lower, left and right side plates in the periphery that is fixed in base plate 1, and floor 2 is arranged on the base plate 1; Have hole clipping 4 on side plate 3 and the floor 2; Base plate 1 is a right-angled trapezium, and it highly is the height of standard steel template, and its epipleural length is shorter than lower side panel length.The epipleural length of Special-shaped Steel Formwork 5 is the lower side panel length of Special-shaped Steel Formwork adjacent above it, and lower side panel length is the epipleural length of Special-shaped Steel Formwork adjacent below it.Be to dock with the U-shaped card between two adjacent forms, carry out bolt with inner formword then through the hole clipping of side plate.
Shown in Figure 2 is the lateral view of Fig. 1, and hole clipping 4 is arranged on the side plate 3; Fig. 3 is an A place partial enlarged drawing among Fig. 1, and side plate 3 is fixedly connected with floor 2.
Embodiment:
13.45 meters of chimney wall zero rice radiuses, the gradient 4% contracture is pressed the actual ratio setting-out on CAD, confirm that chimney wall divides 12 regional contractures, 9 big zones and 3 zonules.7.26 meters of big regional arc length add 1 special-shaped template by 7 standard forms and form; 6.36 meters of zonule arc length add 1 special-shaped template by 6 standard forms and form.
According to contracture zone and scope, 30 groups of the special-shaped contracture steel forms of design butt joint:
960（930）㎜×1500㎜、930（900）㎜×1500㎜、900（870）㎜×1500㎜、
870（840）㎜×1500㎜、840（810）㎜×1500㎜、810（780）㎜×1500㎜、
780（750）㎜×1500㎜、750（720）㎜×1500㎜、720（690）㎜×1500㎜、
690（660）㎜×1500㎜、660（630）㎜×1500㎜、630（600）㎜×1500㎜、
600（570）㎜×1500㎜、570（540）㎜×1500㎜、540（510）㎜×1500㎜、
510（480）㎜×1500㎜、480（450）㎜×1500㎜、450（420）㎜×1500㎜、
420（390）㎜×1500㎜、390（360）㎜×1500㎜、360（330）㎜×1500㎜、
330（300）㎜×1500㎜、300（270）㎜×1500㎜、270（240）㎜×1500㎜、
240（210）㎜×1500㎜、210（180）㎜×1500㎜、180（150）㎜×1500㎜、
150（120）㎜×1500㎜、120（90）㎜×1500㎜、90（60）㎜×1500㎜
With the splicing of aliging with standard form of these Special-shaped Steel Formwork, cross the hole clipping of side plate with the U-shaped cartoon and fix butt joint; Carry out bolt with inner formword again, placing of concrete then, last chimney moulding.The chimney appearance of building up does not so then have faulting of slab ends and neat appearance, has reduced the waste to steel form relatively yet.
These embodiment are not limited only to the protection domain of the utility model, all based on the basic thought of the utility model and make amendment or the protection domain that all belongs to the utility model that changes in.
