Description

A kind of bamboo bits concrete blinding

The invention relates to concrete blinding and using method thereof.Say so in more detail about enough intensity, in light weight, maneuverable concrete blinding is arranged.

Concrete blinding in the past often as shown in Figure 7, at mid portion lathing 53, is followed closely baffle plate 51 in the profile of framework 52 and is made.Generally a plurality of concrete blindings are assembled with nail then.

But present situation is that the manufacturing of this type of concrete blinding and the assembling of a plurality of concrete blindings are to be made by special template craftsman.Because the age increases, template craftsman's quantity reduces, and does not in time train successors again, and therefore, it is very difficult that the manufacturing of later concrete blinding and the assembling of a plurality of concrete blindings will become.

And at home forest reserves poorness now, concrete blinding is used the compoboard of Nan Yang timber more, the use of Nan Yang timber has following problem.

1. because though still generally use compoboard, there is the problem of using south sea timber in being increased sharply and viewpoint such as earth ecology balance of environmental protection consciousness.

2. because being increased sharply and viewpoint such as earth ecology balance of environmental protection consciousness, the felling of Nan Yang timber has become difficulty.

3. again, the price that is related to above-mentioned 2. Nan Yang timber sharply increases, and envisioning from now on, price will continue to rise.

4. often use age of tree height and tall and big log because be used for the compoboard of concrete blinding, so big to the influence of environment.Again because the efficient use of log that drops into less than 7 one-tenth, waste very serious, so far do not reach effective utilization of the forest reserves.

Therefore, can envision and use Nan Yang timber to make the material of concrete blinding with compoboard, more and more difficult from now on.

Moreover general concrete blinding uses the back will remove the dirt on baffle plate 51 surfaces and attachment etc. as use next time.Attachment etc. remove often handwork, become a low reason of template operating efficiency.

The present invention is in view of this type of problem, and purpose is to provide intensity, durability good, and is in light weight and price is low, and the concrete blinding of making easily and the using method of not removing the concrete blinding of attachment etc.

Concrete blinding of the present invention is the concrete blinding that has baffle plate, framework and lath, it is characterized in that: above-mentioned baffle plate, framework and lath are by extrusion modling the mixed material that has mixed bonding agent in the bamboo bits to be squeezed into one.

Again, the using method of concrete blinding of the present invention is the strippable cladding material of surface coverage at the concrete blinding of claim 1 record.

The present invention so need not ailing, makes the concrete blinding of any size and shape because of extrusion modling baffle plate, framework and lath one-shot forming easily.

Again, because baffle plate, framework and lath are by extrusion modling the mixed material that has mixed bonding agent in the bamboo bits to be squeezed into one, so, can make at a low price keeping very high intensity and durability, lightweight while.

Moreover, because of at the strippable cladding material of the surface coverage of concrete blinding, so, after the concrete pouring, unload concrete blinding and can peel off cladding material from template surface, so do not pollute template surface, non-cohesive concrete need not to clean the template after the use.

One embodiment of first invention, Fig. 1 are the phantom drawings of the concrete blinding A relevant with first embodiment, and Fig. 2 is an II-II line cross section view among Fig. 1.

Concrete blinding A is made of baffle plate 1, framework 2 and lath 3 as shown in Figure 1.

And, form a plurality of connections in laterally (long limit) both sides of template 2 with vertical aperture 21, form a plurality of connections in vertical (minor face) both sides with horizontal aperture 22.

Have again, in the template 2 of present embodiment for long 1000mm * wide 2000mm * thick 45mm, form 3 connections respectively in the transverse direction both sides with vertical aperture 21, the longitudinal direction both sides form two connections respectively with horizontal aperture 22, connect with horizontal aperture 22 and connection and can set according to the big freedom in minor affairs of template 2 with the quantity of vertical aperture 21.Connect with horizontal aperture 21 and connect and freely to set, but in the explanation of back, when a plurality of template A connect up and down, be preferably formed as in guaranteeing stable position with the formation position of vertical aperture 22.

Again, the connection of concrete blinding A is not to be necessary with vertical aperture 21 and horizontal aperture 22, and is the same with former concrete blinding (with reference to Fig. 7), and template also can connect each other.That is,, but improve the viewpoints such as operating efficiency of template, be preferably formed as and resemble present embodiment and connect with vertical aperture 21 and connection with horizontal aperture 22 from hope if the mutual ailing equijoin of template A is got final product.

Constituting baffle plate 1, framework 2 and the lath 3 of concrete blinding A, as shown in Figure 2, is by extrusion modling the mixed material 4 that has mixed bonding agent in the bamboo bits to be squeezed into one.

Bamboo bits are ground into bamboo wood etc. and are processed into.Pulverize material for bamboo wood, be applicable to well-known bamboo bits.

Bonding agent is meant: can make bamboo bits bonding any bonding agent, resin etc. between mutually, for example, can adopt poly-peace fat bonding agent.

And, the mould of definite shape is advanced in mixed material 4 fillings of having sneaked into bonding agent in bamboo bits, under HTHP by the one-body molded manufacturing concrete blinding A of extruding.

Moreover, set the size of concrete blinding this moment by the big freedom in minor affairs of the mould that uses.

The following describes the method for using a plurality of composition large-sized concrete templates.

As shown in Figure 3, horizontally join respectively as long as concrete blinding A vertical reached, be communicated with to connect respectively each other with vertical aperture 21 and connection with horizontal aperture 22 at adjacent concrete blinding A, be engaged in vertical aperture in vertical aperture 21 of connection with pin 23, horizontal aperture is engaged in pin 24 in the horizontal aperture 22 of connection, just can assembles and finish.Vertically aperture is the club-shaped materials that only formed tapering on its surface with pin 23 and horizontal aperture with pin 24, and not necessarily leaves no choice but form tapering on its surface.But,, form awl also so be preferably in its surface because of easily coming off from vertical aperture 21 and horizontal aperture 22.Again,, but consider at baffle surface and add very big pressure, should select the high material of shear strength for use if with pin 24 adjacent concrete blinding A is connect each other mutually with pin 23 and horizontal aperture with vertical aperture then can adopt any material.

If resemble the concrete blinding A that uses present embodiment above, can obtain following effect.

1. be main material because of chip, so material is evenly indeformable, again because of obtaining enough intensity and durability, so can easily make the large-sized concrete template with bamboo wood.

2. because of baffle plate is one, so concrete to cast face very beautiful.

Even if 3. the fiber very thin thickness because of bamboo wood also can obtain enough intensity, thus in light weight, be very easy to operation again.For example: the intensity of the concrete blinding of the intensity of the concrete blinding A of thickness 6mm and the former compoboard of used thickness 12mm is almost equal.

4. can assemble a plurality of concrete blindings or dismountings with pin 23 and horizontal aperture with pin 24 with vertical aperture, so the assembly and disassembly efficiency of operation of template is improved significantly.Again because of not using nail etc., so beautiful appearance.

5. short campaign because of bamboo wood, so can stablize supply, price movement is few, so a large amount of productions of concrete blinding A become possibility.Therefore, can make cheap concrete blinding A.

6. because of concrete blinding A is that main material is not perishable with bamboo wood, in the time of not, can pulverize repeated use at an easy rate, can accomplish and effectively utilize resource.

7. because whole bamboo bits that can be used as of bamboo wood use, so not waste fully.
