Abstract

The utility model relates to a flexible winding template. The flexible winding template is composed of a flexible winding plate, an adhesive tape, and a fastening flange. The flexible winding template uses a cylindrical template which is wound by a flexible thin plate to substitute various kinds of wood templates, steel templates, or steel-wood templates which are traditionally used, and therefore, the problem that the cylindrical template is difficult to manufacture is overcome. The cost of the flexible winding template is lowered 70-80%, and the labor consumption of template support and disassembly in construction is only one fifth of that of the wood template.

Description

Flexible winding suttering

The utility model relates to a kind of building form.

The template that placing of concrete is used is a kind of construction appliance that has a large capacity and a wide range in the civil construction project.Developing history from template, the first generation is a wooden form, the second generation is a steel form, the third generation then is steel framework one deck moulding plywood, no matter but that a kind of template among this three generations, all be to adopt hard material to make, exist that weight is big, cost is high, makings is complicated, prop up and tear loaded down with trivial details, as also need to be equipped with large-scale facility such as crane when watering large-size concrete post problem open, brought considerable difficulty to construction operation.

The purpose of this utility model provide a kind of new, particularly be applicable to the template of cylindrical concrete column, that this template should have is in light weight, tear characteristics easy, with low cost open.

The purpose of this utility model realizes by adopting flexible roll bending.Below in conjunction with accompanying drawing to this novel being described in further detail.

Fig. 2 is the expanded view of flexible roll bending;

Glued construction sectional drawing when Fig. 8 is butt joint.

The utility model is made up of flexible roll bending 1 and adhesive tape 2.Wherein, flexible roll bending 1 is a cylindrical shape of reeling and forming, and concrete to be poured gets final product can in this cylinder.The cylinder of reeling adopts adhesive tape 2 that its tail end is cemented on the outer wall, thereby forms a firm template.

In order to make the cylinder size of reeling at the scene accurate, flexible roll bending 1 can be launched, it after the expansion rectangular thin plate, leave some ligulate tenons on one side of its rectangle, parallel with it opposite side is then left the emissions groove seam of respective numbers, and spacing between the two is several times of concrete column diameter dimension to be poured.Like this, when being wound into the cylinder template, these ligulate tenons insert the corresponding line of rabbet joint, thereby have guaranteed the accurate of cylinder size, continue the flexible roll bending 1 of scrolling then, make it can twine some circles once more.In theory, if the intensity of plate is enough, how the circle of reeling can use, but in order to ensure allowing some leeway, generally is advisable with three circles.

In order to strengthen the intensity of flexible winding template, and prevent that in construction two ends are damaged up and down, use upper flange 3 and lower flange 5 bandings at the two ends up and down of flexible roll bending 1 respectively.Described upper flange is made up of identical two halves, and the basic demand in its cross section is the semicircle hoop of two different-diameters that fuse, and larger-diameter one is locked on the upper surface of template, in order to the fixed form size.Than a position of minor diameter thereon, less because of its diameter, then can protect in construction unlikely by facility or concrete damage template.Two parts of flange tighten together with stay bolt.Described lower flange 5 also is made up of identical two halves, with upper flange different only be that its circular boop diameter is not two but one.The circular boop of last lower flange should have certain height, generally should be more than 50 millimeters.

When watering long concrete column, the height of single flexible roll bending 1 may be not enough, in order to solve this problem, can adopt two flexible roll bendings to be docking together, and its joint is bonded together with joint strip, and flange 4 in the outer ring of joint puts, and give banding.In flange 4 basic identical with lower flange 5, different in shape, just on its interior circle, a higher semicircle backplate is arranged respectively, so as simultaneously can with about two flexible roll bendings give banding simultaneously.

Flexible roll bending can adopt metal sheet roof covering or nonmetal thin plate, and the former is as iron plate, and the latter such as plastic plate etc. all can use.If adopt the ABS plastic extrusion board, the optional 1-2 millimeter of thickness, this sheet material, its intensity, flexible and more suitable from weight average.Adhesive tape can adopt the adhesive tape that is added with fiber; Flange can adopt metal flange, also can adopt on-the-spot wooden flange.

During construction,, carry out flexible roll bending, by scrolling roll bending shown in Figure 3, make the ligulate tenon all enter the line of rabbet joint then,, make the abundant rolling-in of roll bending, guarantee between each layer not loosening with binding device (as " baling press encircling device ") reinforcing according to concrete column diameter to be poured.Cement with the horizontal sticking perps of adhesive tape then, its spacing is about 40 centimetres one.Can guarantee after gluing that roll bending does not unclamp.Use the upper and lower opening of flange stationary cylinder shape roll bending at last, centering is in place, is located with seizing wire and earth anchor, gets final product placing of concrete.During form removal, unload lower flange, tear adhesive tape off, peel off flexible roll bending, clean promptly reusable with wet cloth.

The scheme that adopts the utility model to provide is made template, and is simple, easy to operate.Template is reusable more than 50 times, props up the worker that disassembles and uses and only is 1/5th of wooden form, and cost can be saved 70-80%, and economic benefit is very remarkable.Though this is novel mainly is to make cylindric template, and its principle and structure may extend to ellipse, square or other prismatic template gets on.

Claims

1, a kind of flexible winding template is characterized in that it is made up of flexible roll bending 1 and adhesive tape 2, and wherein, flexible roll bending is a cylindrical shape of reeling and forming, and 2 tail ends with flexible roll bending 1 of adhesive tape are cemented on its outer wall.
