Description
Technical field
The utility model is a kind of equipment that is applied to the construction of civil engineering cast-in-place concrete structure, belongs to the field that civil engineering plant and equipment are made.
Background technology
In April, 2003 is in " international conference of fabric applications technology " in Frankfort, the experts and scholars of 7 inferior dark industrial technology universities of Germany and Universitaet Stuttgart jointly deliver the paper that is entitled as " fabric strengthens concrete monolithic template ", having introduced them in the literary composition adopts extrusion formation equipment and high-strength stereo fabric to make performance and the method (Brameshuber that fabric strengthens concrete monolithic template, W., Koster, M., Hegger, J., Voss.S., Gries, T., Barle, M., Reinhardt, H.-W., Kr ü ger, M.: TextileReinforced Concrete (TRC) for Integrated Formworks.In:12.Internationale Techtextil-Symposium f ü r technische Textilien, Vliesstoffe und textilarmierte Werkstoffe..Messe Frankfurt GmbH, 07.04.03-10.04.03, Frankfurt.Frankfurt:2003,4.23.).Method that Wen Zhongshu draws and technology are too complicated, and do not state the application process that draws in construction.
The formwork material that patent adopted that name is called " light weight disposable building form and manufacture method thereof (CN97116459.2) " and " light weight disposable building form (CN97225953.8) " is glass fiber or fabric reinforced cement shell, but its manufacture craft is too complicated, is difficult at the construction field (site) finish; It or not the jigsaw formula.
In the Shi Xuping that manages development departments of 18 innings of groups of iron in " railway type design " 2003 (7), deliver and be entitled as " cast-in-place GRC formwork concrete dense rib floor construction technology " literary composition and introduced job practices with the dull and stereotyped splicing of GRC formwork, the joining method of plate simple coarse too in the article causes stress to be concentrated easily plate is damaged.And the bed die of beam and formwork are not an integral body, and the position, axis of therefore constructing is restive.
Summary of the invention
Technical problem: the purpose of this utility model provides the assembling unit of the permanent plane of a kind of part concrete component jigsaw formwork, the jigsaw formwork that uses this device to constitute, its formwork can repeat turnover and use, and help reducing cost, good looking appearance, the size of plate are not limited by modulus.And can make not spillage of formwork and formwork seam crossing.
Technical scheme: the splicing apparatus of plane of the present utility model concrete jigsaw formwork comprises strip fixedly section bar, bolt, nut, steel plate bar with holes; Wherein, the strip fixedly cross section of section bar is trapezoidal, be provided with one in the centre of trapezoid cross section along the fixing T-slot of section bar length direction of strip, the bolt head of bolt is arranged in this T-slot, the slotted hole on the steel plate bar with holes is passed in the other end of bolt, is spun on the bolt by nut steel plate bar with holes is pressed on the flat thin plate of formwork.Bolt head on the bolt is oval-shaped, and long axis of ellipse is slightly less than the fixedly width of the T-slot in the section bar of strip, and oval minor axis is identical with the screw diameter of bolt.The both sides of steel plate bar with holes bend to right-angle side, and the cross section that makes steel plate bar with holes is a U-shaped, are provided with slotted hole separately along its length in the centre of steel plate bar with holes.
Beneficial effect:
1. flat thin plate is done formwork and is no longer used the nail assembly unit, can easily flat thin plate be assembled into the full wafer formwork with the device of this case.With nonvolatil colored hard strip section, not only make the formwork assembly unit convenient, and, make after structure finishes, do not need to do in addition finishing, the ceiling pattern is attractive in appearance.Formwork thickness of slab and the thin portion of colored strip section relation between geometrical shape have been set up in the invention.The establishment of these geometric relationship makes each several part materials economy, the assembly unit compactness.
2. relevant geometric angle and the size when variable color strip section and flat sheet blanking, jigsaw method notion and method that the present invention proposes can be used for building of concrete slabs such as rectangle and prismatic fully.
3. flat thin plate can be repeatedly used in formwork, and part strip section bar and metal fittings are also reusable, therefore, helps reducing cost, energy conservation.
4. all adopted a permanent strip section bar in each flat thin plate seam areas, so the plate seam can spillage.And this, permanent strip section bar again can be as when construction reinforcing bar filler strip, to guarantee the thickness of concrete cover.
5. after construction was finished, the groove in the permanent strip section bar can be placed electric wire etc., also can be used as the finishing skeleton mounting groove of constant weight.
7. pass through to calculate the definite strip metal tie rod with holes and the usage quantity of accessory thereof, can reach and stablize the firm purpose that flat thin plate is linked to be the integral plane formwork and bears certain working load.
