Abstract

The invention provides a curved surface template with an adjustable curvature, mainly used for casting a concrete curved surface template in the construction field, belonging to constructional templates. The curved surface template is characterized in that: the curved surface template is used for the curved surface template with various curvature requirements; the curved surface template is universal, simple in structure, fast in template assembling, and repetitive in use; and the curved surface template can solve the problem that the curved surface template in the existing construction field is not universal. The technical scheme is that: two ends of support beam units (A), (B) can be connected together by bolts (4a), (4b) and can rotate mutually; a rotational angle is adjusted to the angle needed by the curved surface template, and is fixed by a nut (9); a plurality of support beam units (A), (B) are connected to assemble a set of fold line beams according to the method; then other sets of fold line beams are installed; each set of fold line beams are fixed by pull bolts and a support component (C) to form a fold line beam rigid skeleton; the templates are paved on the fold line beams; and the templates are connected by countersunk head bolts.

Description

The adjustable curvature circular formwork

One, technical field

The present invention is mainly used in building operations concreting circular formwork and uses, and belongs to the construction formwork class.

Two, background technology

The circular formwork that the present building operations of China is generally used is the template of customization basically, and the template that both a kind of curvature requires need customize template corresponding, and the different curvature template can not be general, causes a large amount of wastes of template.In addition, its structure of adjustable circular formwork of existing several granted patent is complicated, needs to use more auxiliary adjustment parts, installs and uses inconvenience.

Three, summary of the invention

The present invention has overcome the problems referred to above, and it is quick for installation, easy to use, can require to be mounted to different circular formworks according to different curvature, has versatility and also can repeatedly use.

The present invention is made up of brace summer unit A (A '), brace summer unit B (B '), template C, supporting member D.Brace summer unit A (A ') form by connection mode plate hole 1 (1 '), arcuate socket 2 (2 '), connecting hole 3, set bolt 4a, 4b, nut 9.The brace summer unit B is with brace summer unit A, and just the edge of a wing, top of its edge of a wing, top and brace summer unit A is reverse; Supporting member D is made up of link slot 6, rod member 7.Annotate: set bolt 4a, 4b are welded on brace summer unit A and the B.

Below in conjunction with annexed drawings set forth concrete operating principle of the present invention

Formation referring to accompanying drawing 1, Fig. 3, Fig. 4, Fig. 5, Fig. 2, Fig. 2 a explanation convex polygonal beam.

Bolt 4a, the 4b of brace summer unit B are inserted in the hole 3, arcuate socket 2 of brace summer unit A, the brace summer unit B can be around the bolt 4a of 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, 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 brace summer unit B and A with nut 9 fixed support beam element B and A, with alternate successively again connection brace summer unit A of the method or B, just forms one group of polygonal beam up to required angle, with said method many group polygonal beams is installed again.

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

Pass the support beam A or the B hole 5 of two adjacent groups correspondence 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 rod member 7, and rod member 7 can be regulated height) of link slot 6 insertion brace summer unit A or B, the height of adjustment rod member 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.

With dormant bolt 8 pass hole 1 that pattern hole is screwed into brace summer unit A or 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 forms; 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 again.Attention: brace summer unit A or B are to be connected at its two ends with template, 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.Brace summer unit A ' or B ' are to be connected therebetween rather than the two ends connection with template.

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, but should be the brace summer unit A ' of concave curvatures in the previous brace summer unit at the flex point place of convex surface and concave curvatures.

Five, specific embodiment

With regard to a rounded roof template formwork application of the present invention is described below

The rounded roof template belongs to the convex surface template,

Earlier two groups of polygonal beams are installed, are fixed this two groups of polygonal beams with split bolt again, form longitude horizontal bracing by the mounting method of convex polygonal beam; Support these two groups of polygonal beams with supporting member C and form vertical support, all the other are installed successively as stated above respectively organize polygonal beam and longitude horizontal bracing and vertical the support, polygonal beam and support system just form a rigid backbone like this, again in polygonal beam upper berth template, connect template with dormant bolt and get final product.Attention: for the convex surface template, dormant bolt connects template in the end of brace summer unit A or B.
