Description

The using method of concrete blinding

The present invention relates to the using method of concrete blinding, specifically, relate to a kind of using method that can increase access times, easy to operate concrete blinding.

Concrete blinding before mostly is structure shown in Figure 8, and promptly the pars intermedia nail at frame 52 has horizontal stripe 53, baffle plate 51 at a face nailing of frame 52.Several concrete blindings are assembled with nail usually.

But, the work of making this concrete blinding and assembling several concrete blindings all is that the form fixer by sole duty bears, reason owing to aging, form fixer's number day by day reduces and leaves no successor, therefore, the assembling of the making of this concrete blinding and several concrete blindings becomes very difficult.

In addition, concrete blinding adopts the composite plate of Nan Yang timber system more, in the modern times of forest reserves poorness, uses Nan Yang timber that following problem is arranged.

(1) considers that from the viewpoint of the reinforcement of environmental consciousness and the ecological homeostasis of preserving our planet etc. the felling of Nan Yang timber is very difficult.

(2) 1. because above-mentioned, the price of Nan Yang timber sharply rises, and estimates also can continue from now on high price.

(3) be used in composite plate on the concrete blinding, adopt the high large-scale log of the age of tree to make more, thus big to ambient influnence, and also the effective rate of utilization of log has only 70%, and waste is a lot, can not effectively utilize the forest reserves.

Therefore, the composite board material that adopts Nan Yang timber to use as concrete blinding will be more difficult from now on.

In addition, concrete blinding in order to reuse, must be removed the dirt, Fu Zhe on baffle plate 51 surfaces etc. after using, and these removals of paying thing mostly are handwork, and this also is one of low reason of template operating efficiency.And the access times of template itself are also few.

The present invention makes in view of the above problems, its purpose be to provide a kind of access times many, need not clean the using method of paying the low concrete blinding of thing and operating expenses.

The feature of concrete blinding of the present invention is: the surface with plastics system concrete blinding of baffle plate, frame and horizontal stripe covers and assembles with strippable coating member, has built after the concrete, pulls down this concrete blinding, throws off above-mentioned coating member.

The present invention is owing to be with plastic shaping baffle plate, frame and horizontal stripe to be shaped to an integral body, so need not nail etc., can make the concrete blinding of any size shape easily.Simultaneously owing to having enough intensity and durability, so access times are many.

In addition, because the surface of concrete blinding covers with strippable coating member, behind the concreting, pull down concrete blinding, throw off coating member from template surface, so, template surface can not made dirty can not adhere to a part of concrete yet, need not clean template after the use.Therefore can reduce operating expenses.

Below, with reference to the description of drawings embodiments of the invention.

Fig. 1 is the stereogram of the routine concrete blinding A that adopts among the present invention, and Fig. 2 is the II-II line profile among Fig. 1.

As shown in Figure 1, this concrete blinding A is made of baffle plate 1, frame 2 and horizontal stripe 3.This is not limited to this shape as just an example.

Laterally (long limit) direction both sides along frame 2 form several vertical apertures 21 that connects usefulness, form the horizontal aperture 22 of several connection usefulness along vertical (minor face) direction both sides of frame 2.

In the present embodiment, be on the frame 2 of vertical 1000mm * horizontal 2000mm * thickness 45mm, form vertical aperture 21 of 3 connection usefulness respectively in its both lateral sides, form the horizontal aperture 22 of 2 connection usefulness respectively in its vertical both sides, vertically the number of aperture 21 and horizontal aperture 22 can be set arbitrarily according to the size of frame 2.Vertically the position of aperture 21 and horizontal aperture 22 also can freely be set, but as described later, when several templates A was linked together up and down, these apertures should be located on the position that helps form stable.

In addition, the connection on the concrete blinding A with vertical aperture 21 and laterally aperture 22 be not to be essential, also can adopt with the same mode of concrete blinding (see figure 8) before template is connected with each other.That is, can be connected with each other template A, but consider, still resemble present embodiment and form like this to connect and be advisable with vertical aperture 21 and horizontal aperture 22 from the angle that improves the template operating rate with nail etc.

This concrete blinding A is made of plastics, and with metal pattern moulding (moulding by casting or compression moulding etc.), can make shape and size arbitrarily easily.The kind of used plastics is not limit, as long as have essential intensity and durability.Representative have polyethylene, a polypropylene etc.Polyethylene and polypropylene can be high temperature resistant, because of the distortion that the sunlight direct projection produces little.

In addition, plastic shaping can be made any pattern easily, and the surface of template can not only be made plane, and can also make the concavo-convex opposite pattern form of laying brick or stone style.

Below, the method with several concrete blindings A assembling large-sized concrete template is described.

As shown in Figure 3, the limit in length and breadth of each concrete blinding A is joined respectively, the connection of adjacent concrete template A communicates respectively with vertical aperture 21 and horizontal aperture 22, as long as vertical aperture is embedded in the vertical aperture 21 that links to each other with pin 23, horizontal aperture is embedded in the horizontal aperture 22 that communicates with pin 24, just finished assembling operation.Vertically aperture with pin 23 and laterally aperture are rod-like members that the surface becomes inclination slightly with pin 24, but also nonessentially tilt, but for the ease of embedding with deviate from, vertical aperture 21 and horizontal aperture 22 are advisable with the surface of making inclination.Vertically aperture is not limit with the material of pin 24 with pin 23 and horizontal aperture, as long as can couple together adjacent concrete template A.But big pressure will be born in the surface of considering baffle plate 1, bears the big material of shear stress so preferably select for use.

Use the concrete blinding A of present embodiment to have following effect.

(1) owing to be that material is even with plastic, be out of shape for a short time, have enough intensity and durability, be convenient to make the large-sized concrete template.

(2) the retaining end 1 is a monoblock, and the concreting face that is processed into is attractive in appearance.

(3) only several concrete blindings are assembled with pin 24 with pin 23 and horizontal aperture, can dismantle, can increase substantially the mounting or dismounting efficient of template with vertical aperture.In addition, because without nail, outward appearance is also good-looking.

(4) polyethylene, polypropylene can be high temperature resistant, so that direct sunlight in full summer shines is also indeformable down.

(5) if the surface of template is formed the opposite concaveconvex shape of laying brick or stone pattern etc., then water the concrete surface that builds up and just form the pattern of laying brick or stone, very convenient.

Fig. 4 is the stereogram of concrete blinding B used in the present invention.

This concrete blinding B and above-mentioned concrete blinding A are same, also are made of baffle plate 1, frame 2 and horizontal stripe 3, and the bending that roughly meets at right angles along its length of baffle plate 1 surface is cut up with a hay cutter in the bight of bending, form section along short side direction and are the circular groove 11 of band.In order to make the thickness around the groove 11 roughly the same, at the outer periphery formation protuberance of groove 11 with other segment thicknesses of concrete blinding B.Remaining structure is basic identical with the concrete blinding A of Fig. 1, and identical part represents that with same Reference numeral its explanation is omitted.In addition, same with the concrete blinding A of the 1st embodiment, concrete blinding B also makes of plastic shaping.

Fig. 5 is the stereogram of concrete blinding C used in the present invention.

This concrete blinding C and above-mentioned concrete blinding A are same, also are made of baffle plate 1, frame 2 and horizontal stripe 3, and forming section at the roughly middle place on baffle plate 1 surface along short side direction is semicircular groove 12.Outer periphery at groove 12 forms protuberance, so that other segment thicknesses of thickness around the groove 12 and concrete blinding C are roughly the same.Concrete blinding A basic and Fig. 1 is basic identical for remaining structure, and identical part represents that with same Reference numeral its explanation is omitted.In addition, same with the concrete blinding A of the 1st embodiment, concrete blinding C also makes of plastic shaping.

Except the concrete blinding C of above-mentioned concrete blinding B and the 3rd embodiment, the shape of baffle plate 1 part can also be set other arbitrary shapes for.

Below, the situation that concrete blinding A, B, C are combined and use is described.

For example as shown in Figure 6, there is circular cross section projection 14 in the bight, used template describes when pars intermedia has the building M of semicircle section projection 15 to being built in.

Use concrete blinding A in straight portion, use concrete blinding B, use concrete blinding C in the part that forms the semicircle section projection 15 of pars intermedia in the part that forms bight circular cross section projection 14.Promptly, the both sides of template B join with template A and template C respectively, between template A and template B and between template B and the template C each is connected with horizontal aperture 22 and communicates respectively, in the horizontal aperture 22 that horizontal aperture is communicated with pin 24 embeddings, can assemble template A, B, C at transverse direction.In addition, top and another template B of template B joins, and the connection between the template B communicates respectively with vertical aperture 21, and vertical aperture is embedded in the vertical aperture 21 that communicates with pin 23, just can assemble template B in longitudinal direction (short transverse).Use the same method and also can assemble template A, template C at longitudinal direction.

When being used in combination concrete blinding A, B, C as described above, except effect, also has following effect with above-mentioned use concrete blinding A.

(1) except building the building that the bight is square angle, can also build the building of bight band circular cross section projection, the semicircle section projection of pars intermedia band, can build the beautiful and rich building that changes of outward appearance easily.

(2) bight is the building at square angle, and the sound of wind is very high when strong wind, and the building of bight band circular cross section projection is little to the resistance of wind, can suppress the sound of wind, and is particularly suitable at windy area.

When (3) using concrete blinding A, B, C, can carry out the concrete operation of building under the state of window frame installing, faster and easy than before back dress welding method construction.But therefore the reduction of erection time, reduce operating expenses.

Fig. 7 is the profile of concrete blinding D.This concrete blinding D bends to arch, is made of external mold D1 and internal mold D2.External mold D1 and internal mold D2 are combined, and concreting just can produce the concrete wall that is the arch bending betwixt.Remaining structure is basic identical with the concrete blinding A of Fig. 1, and identical part is shown with same accompanying drawing and remembered and represent that its explanation is omitted.

Below, the using method of concrete blinding A of the present invention, B, C, D is described.
