Abstract

The utility model discloses an air exhaust and water drainage template which comprises a template main body (1), a nonwoven cloth (2) and a nonwoven cloth (3). The template main body (1) is a common wooden template, a steel template, a plywood template and a bamboo rubber template. The fluffy nonwoven cloth (2) is stuck together with one surface of the template main body (1) and the template rim connected with the surface. The nonwoven cloth (3) has high density, has the functions of air ventilation and water permeation, and cannot be stuck together with hardened concrete. When concrete pouring is carried out at the construction site and prefabricated concrete parts are produced in a factory or at the prefabrication site, the air exhaust and water drainage template can remove air and water in concrete coming close to the template from the position of the nonwoven cloth (2) at the rim of the template, thereby improving the surface quality of the concrete, prolonging the service life of the concrete, and beautifying the appearance of the concrete.

Description

Exhaust, draining template

Technical field

The invention belongs to the concrete construction field, the exhaust, the draining template that relate to a kind of concreting at the construction field (site) and when factory or precasting yard production concrete prefabricated element, use.

Background technology

At present; at the construction field (site) concreting and when factory or precasting yard are produced concrete prefabricated element wooden form commonly used, steel form, plywood form, bamboo blanket template; this class template does not possess the function of draining, exhaust; use the concrete surface of this class template often to have defectives such as honeycomb, pitted skin, sand holes, crackle; these defectives have not only influenced the attractive in appearance of concrete surface; and reduced durability of concrete, shortened concrete application life.

Summary of the invention

The purpose of this invention is to provide a kind of exhaust, draining template.

For achieving the above object, technical scheme provided by the present invention is: a kind of concrete blinding, include the nonwoven of main template body, one deck puffy and one deck is ventilative, permeable and not can with the sclerosis after concrete binding high-density non-woven fabrics together, the nonwoven of described puffy and the one side of main template body and the template edge that links to each other with this face stick together, and described another layer is ventilative, permeable and can not be by heating, pressurizeing formation afterwards to be handled on the surface of the nonwoven of puffy with the concrete binding high-density non-woven fabrics together after the sclerosis.

Described main template body is wooden form, steel form, plywood form, the bamboo blanket template of using always.

The invention has the beneficial effects as follows, when moulding is vibrated in concreting, from concrete, move near the water and air the template, enter the nonwoven of puffy behind ventilative, the pervious layer by exhaust, draining template, from the puffy nonwoven of template edge, discharge then.

At the construction field (site) concreting and when factory or precasting yard are produced concrete prefabricated element, use exhaust, draining template after, can improve concrete surface quality, prolong concrete application life, beautify concrete outward appearance.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail, but content of the present invention be not limited to for embodiment.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a sectional drawing of the present invention.

The specific embodiment

Accompanying drawings embodiment is as follows:

Template as shown in Figure 1, be to paste the nonwoven (2) of going up puffy on the surface of template (1) (wooden form, steel form, plywood form, bamboo blanket template) commonly used, by the method for heating, pressurizeing the surface of the nonwoven (2) of puffy is handled again, make the nonwoven surface of puffy form one deck ventilative, permeable and not can with the concrete binding high-density non-woven fabrics layer (3) together after hardening.
