Abstract
The utility model relates to a stretch -draw box mould for prefabricating utility tunnel comprises left part spare and right part spare, and left part spare and right part spare constitute by bottom plate, roof, curb plate, and the curb plate of saying comprises preceding curb plate, posterior lateral plate, left side board, right side board, and wherein left part spare posterior lateral plate and right part spare posterior lateral plate are the inclined plane board, and interfitting, its characterized in that: contained angle between left part spare roof and left part spare left side board, the left part spare right side board is the arc chord angle, and the contained angle between right part spare roof and right part spare left side board, the right part spare right side board is the arc chord angle.
Description
Technical field
The utility model relates to a kind of stretch-draw box mould for prefabricated pipe gallery.
Background technology
In prior art, for the stretch-draw box mould of prefabricated pipe gallery (Fang Han), it is made up of left part part and right members, left part part and right members are formed by base plate, top board, side plate, said side plate is made up of front side board, rear side plate, left plate, right side plate, wherein after left part part, after side plate and right members, side plate is inclined-plane plate, and mutually coincide, and plate oblique angle, inclined-plane is 45 degree. The weak point that existing stretch-draw box mould exists is, angle between top board and left plate, right side plate is point angle, prefabricated pipe gallery (Fang Han) limits by mould when building shaping, angle component stress is caused to be concentrated, component easily produces quality defect, and easily snap gauge tool phenomenon grabbed by generation concrete.
Practical novel content
Goal of the invention of the present utility model is to provide a kind of stretch-draw box mould for prefabricated pipe gallery, it is possible to effectively improving quality of concrete members, precast concrete is convenient.
Realize the technical scheme of the present utility model object:
A kind of stretch-draw box mould for prefabricated pipe gallery, it is made up of left part part and right members, left part part and right members are formed by base plate, top board, side plate, said side plate is made up of front side board, rear side plate, left plate, right side plate, wherein after left part part, after side plate and right members, side plate is inclined-plane plate, and mutually coincide, it is characterized in that: the angle between left part part top board and left part part left plate, left part part right side plate is circular arc angle, and the angle between right members top board and right members left plate, right members right side plate is circular arc angle.
After left part part, after side plate, right members, the oblique angle of side plate is 60 degree.
Circular arc angle, right members top board between left part part top board with left part part left plate, left part part right side plate are identical with the circular arc angle between right members left plate, right members right side plate, and circular arc angle is 45 degree of-90 degree, and radius is 2mm-45mm.
The useful effect that the utility model has:
Angle between the utility model left part part top board and left part part left plate, left part part right side plate is circular arc angle, angle between right members top board and right members left plate, right members right side plate is circular arc angle, during concrete component formation, the stress of top board and left and right side plate angle can not produce to concentrate, concrete member should not produce the quality problems that stress is brought, and can effectively improve quality of concrete members. Being circular arc angle between top board and left and right side plate, should not produce concrete and grab snap gauge tool phenomenon, be easy to the demoulding, precast concrete is convenient. Be circular arc angle between top board and left and right side plate, it is possible to use a steel plate utilizes press brake to process at one time top board and two side plates, make simply compared with the angle of protocone angle, welding capacity is few, it is little to be out of shape, cost of manufacture relative reduction.
After the utility model left part part, after side plate, right members, the oblique angle of side plate is 60 degree, stretch-draw box left and right parts can be processed simultaneously, then common band saw lathe corner degree is utilized to cut, the special processing modes such as Linear cut must be used to complete cutting relative to original 45 degree of oblique angles, under the prerequisite not reducing processing quality, it is low that the utility model mould has cost, is easy to the advantage of processing.
Accompanying drawing explanation
Fig. 1 is the side-view of the utility model stretch-draw box mould left part part;
Fig. 2 is the side-view of the utility model stretch-draw box mould right members;
Fig. 3 is the front view of the utility model stretch-draw box mould.
Embodiment
Stretch-draw box mould is made up of left part part and right members combination. As shown in Figure 1, stretch-draw box mould left part part is made up of side plate 5, left part part left plate, left part part right side plate after left part part base plate 4, left part part top board 2, left part part front side board 1, left part part, as shown in Figure 2, stretch-draw box mould right members is made up of side plate 9, right members left plate, right members right side plate after right members base plate 6, right members top board 7, right members front side board 8, right members. After left part part, after side plate 5, right members, side plate 9 is inclined-plane plate, mutually coincide, and oblique angle is 60 degree.
Angle between left part part top board and left part part left plate, left part part right side plate is circular arc angle, and the angle between right members top board and right members left plate, right members right side plate is circular arc angle. Circular arc angle, right members top board between left part part top board with left part part left plate, left part part right side plate are identical with the circular arc angle between right members left plate, right members right side plate, circular arc angle is 45 degree of-90 degree, and radius is 2mm-40mm, in the present embodiment, as shown in Figure 3, radius is 25mm.
