Description

Construction formwork polyethylene flat panel

Technical field:

The utility model relates to a kind of construction formwork panel, especially a kind of construction formwork flat panel.

Background technology:

As shown in Figure 1, the general construction formwork that uses is made up of with the outside framework 103 that is arranged on the inside edge the inner frame 101 of four jiaos of profile plate bodies 102 and set within it at regular intervals side and support panel body with flat panel 100, and these frameworks are made by metal.The panel of this structure generally is used for the wall template on the many building site of the construction repeatedly of single plane, and the side pressure that concrete brought is distributed to inner frame and outside framework, prevent that effectively the panel body is impaired, therefore have the advantages such as access times that increase panel.And the panel body of this structure is generally made by the strong wooden composite plate of counter-bending ability, and composite plate is bonded at concrete easily, even coat release agent, its surface is easy to damaged in knockout course, so it uses repeatedly and has been subjected to considerable restraint.On the other hand, the template panel that appearance is recently made by synthetic resin, this is a kind of distortion panel of using synthetic resin material substitution composite plate on the basis of above-mentioned panel, and this panel body and compoboard are with similar form moulding, but compare with composite plate a little less than its counter-bending ability, increase the inner metal bezel frame, overall weight increases thereupon, carrying and installation inconvenience are difficult for adopting on the building site.In addition, in the construction and the interchangeability between other panel poor, so material is bought burden; This in addition panel is easy to demoulding when underwater work, easily get rusty, and therefore in order to prevent that it from getting rusty, the additive decrementation management fee; On the other hand, can't restore to the original state with manpower when being distorted phenomenon after repeatedly using, the used chemicals and the waste water of generation can cause the serious environmental pollution when scrapping.

Summary of the invention:

The utility model is in view of construction formwork existing weak point in the flat panel present situation, providing a kind of is major ingredient with the polyethylene, the construction formwork of panel and skeleton forming one polyethylene flat panel, alleviate panel weight thus, and improve its interchangeability, prolong its application life, reduce the template processing cost.For this reason, the utility model has been taked following technical measures:

The utility model is by plate positive plane four edged surface plate bodies and several horizontal ribs that are arranged on its back, vertical ribs, the edge ribs is formed, and these structures are by polythene material moulding one, described ribs is divided into panel body back most sub-boxes of identical size and shape, the pairing horizontal ribs of each sub-box and vertical reinforcing rib sides central authorities are respectively equipped with a manhole, the pairing edge of each sub-box reinforcing rib sides central authorities are provided with one or four jiaos of through holes and are provided with manhole in its both sides, edge ribs two ends up and down forms the outstanding framework of formation laterally four jiaos of grooves in two ends up and down except that four jiaos of through hole present positions, and in order to increase intensity of the present utility model, bury the reinforcement iron wire underground in ribs inside, edge, and on four jiaos of through hole present positions, reinforced sheet is set, and these reinforced sheets and reinforcement iron wire are fixed together.

And, add monitor window in each sub-box central authorities in order to observe the concrete formation process.

In addition, the distortion and the destruction of unitary construction are designed to streamlined turning at the mutual cross section of each ribs in order to prevent to install.

Concrete when making template, with the utility model use that combines with formwork tie rod, conductor spacer.

The utlity model has following advantage.

1, the utility model is by polythene material moulding one, therefore have in light weight, anti-in temperature Change, good springiness, do not absorb moisture content, underwater work easily, carrying and characteristics such as easy to install, and its smooth surface, concrete formation rear surface plate is just;

2, interchangeability is good, saves the material buying expenses;

3, strengthen iron wire and reinforced sheet and do not expose, thus non-corrosive, prolonging life of product, and these structures have been arranged, the anti-pressure that is brought when concrete formation prevents distortion, improves durability, improves the quality of product;

4, because the mutual cross section of each ribs forms streamlined turning, reduce elasticity during installation, prevent the distortion and the destruction of constructing;

5, can observe the concrete formation process by monitor window;

6, combine with formwork tie rod, conductor spacer and use to make template, make template indeformable, improve the quality of template.
