Abstract

The utility model provides a curvature adjustable curved-surface template which is mainly used for concrete pouring in the field of building construction and belongs to a building template. The curvature adjustable curved-surface template is characterized in that the curved-surface template can meet the requirements of diversified curvatures, has good universality and a simple structure, can be quickly assembled, can be repeatedly used and solves the problem that the curved-surface template in the present field of building construction is not universal. The technical scheme is as follows: the two ends of supporting beam units (A) and (B) can be connected together by bolts (4a) and (4b) and can mutually rotate; a rotating angle is adjusted to the angle needed by the curved-surface template and is then fixed by a bolt (9); according to the above method, a plurality of supporting beam units (A) and (B) can be assembled into a group of folded beams, and then the rest groups of folded beams are installed; the groups of folded beams are fixed by oppositely-pulled bolts and supporting components (C) to form a rigid skeleton for the folded beams, and then the template connected by countersunk bolts is laid on the folded beams.

Five, the specific embodiment

Below in conjunction with the concrete operating principle of annexed drawings set forth the utility model

The formation of convex polygonal beam is described referring to accompanying drawing 1, Fig. 3, Fig. 4, Fig. 5, Fig. 2, Figure 13.

Bolt 4a, the 4b of convex brace summer unit B are inserted in the hole 3, arcuate socket 2 of convex brace summer unit A, convex brace summer unit B can be around the bolt 4a of convex brace summer unit A rotation like this, and its angle of rotation can determine according to subsequent corrosion.If subsequent corrosion R, the center to center distance h of bolt 4a, 4b, convex brace summer unit A, B length L, then angle of rotation a=2arcsinL/2R.The arc length of arcuate socket 2 (arc length between the distance of center circle) is 2h * arcsinL/2R.The angle of adjusting convex brace summer unit B and convex brace summer unit A is up to required angle, with nut 9 fixedly convex brace summer unit B and convex brace summer unit A, with the method alternate successively again connection convex brace summer unit A or convex brace summer unit B, just form one group of polygonal beam, with said method many group polygonal beams are installed again.

The longitude horizontal bracing that polygonal beam is described referring to Fig. 1, Figure 10 is supported with vertical.

Pass the convex support beam A of two adjacent groups correspondence or the hole 5 of convex brace summer B with split bolt, fix it with nut, Using such method is fixed two groups of polygonal beams, fixes all the other again and respectively organizes polygonal beam, has so just formed the longitudinal bracing of polygonal beam.

With the lower edge (link slot 6 welds together with support bar 7, and support bar 7 can be regulated height) of link slot 6 insertion convex brace summer unit A or convex brace summer B, the height of adjustment support bar 7 makes it close proximity to ground or links to each other with other supporting members.Multi-point support just forms the vertical support of polygonal beam.

Illustrate that referring to Fig. 1 or Figure 11 polygonal beam links to each other with template C.

With dormant bolt 8 pass hole 1 that pattern hole is screwed into convex brace summer unit A or convex brace summer B both can, hole 1 has internal thread.For than the long radius curved surface, directly just can form the convex surface template with dormant bolt 8 fixed form C; For the small radii curved surface,, just can form the convex surface template with using scotch jam-pack broken line and camber line gap behind the dormant bolt fixed form C again.Attention: convex brace summer unit A or convex brace summer B are to be connected at its two ends with template C, and its both upper ends thereof needs chamfering (to see Fig. 2 a).

The formation of concave curvatures template is described referring to accompanying drawing 6, Fig. 7, Fig. 8, Fig. 9, Figure 11.Concave curvatures template mounting method is identical with said method basically, and the position and the convex template of different is its arcuate socket 2 ' and connection mode plate hole 1 ' are different.Concave support beam element A ' or concave support beam element B ' are to be connected therebetween rather than the two ends connection with template C.Referring to Figure 12, for a kind of existing convex surface curved surface the template of concave surface curved surface is arranged again, its mounting template method is identical with said method.

Special explanation: template C can be Bamboo Formwork, wooden form or plastic formwork.
