GLUED WOODEN SHIELD

The utility model relates to the woodworking industry, and often to the production of glued wooden structures, and can be used for the manufacture of products (panels and panels) for both Hecyuuix-oiicTpyKiHiii, and for msec.mi. floors, furnishings, manufacture of panels and other joinery.

Known glued wooden ian.ch. i4Kjiio4ai (iiiui; -i op civiL eselins;;.; ms, ::: on the adhesive using longitudinal grooves and ridges made on the surfaces of the side faces of the bars, and longitudinal grooves are made in the grooves adjacent to the plastic surfaces of the bars ( Aut. St. USSR No. 1458530, IPC E04F 15/04 analogue).

The disadvantage of this analogue is the low strength of the wooden plaque at the place of gluing to bending.

It is also known the connection of parts along the length of wood to the serrated thread :. This is achieved by changing the shape of the mating faces of the parts. The faces are made semicircles n1. Due to this, 11CH1I: 1ethea of the area was significantly increased. e ryag / hmy.kh surfaces of gear spikes. Thus, there is an increase in the area of the adhesive surface. The spikes are located along the surface of the mating half cylinders (Application for invention No. 93031457, IPC F16B 1/00 - analogue).

In the described device, the bond strength is higher, but the bending strength of the bond is also insufficient.

The closest is a glued wooden panel, made in the form of IHPG. including rails (bruskn), connected along the lateral sides in a gear PNSH. at -rroN, the lateral sides are filled with oblique, and the tooth cross section is in the form

of an equilateral trapezoid with an angle of inclination of the side fх aicig и, ГЛС, and - кОм «jiiuuiciir Ipciiiin of wood slats (Aut. St. USSR No. 1761909, IPC E04F 15/04 - prototin).

The disadvantages of the prototype include low productivity, because to obtain the desired connection (two tires and troughs), it is necessary to mill the rail twice and use different milling cutters, which complicates the process.

The problem to which the claimed utility model is directed is to increase productivity in the manufacture of glued products, simplify the process while improving the quality of finished products and the structural strength of the products at the bonding site.

The technical result is achieved through the use of a single cutter, uvs.puniya contact area of the parts to be glued and saving time on the manufacture of products by performing shaped nrofil, on the surface of which gluing occurred, and also by gluing during vertical application of forces when heated in cold and hot press.

The problem is achieved in that in a glued wooden panel, including bars connected to each other along the lateral faces in a toothed pin, moreover, the lateral faces are made oblique, and the tooth cross section is in the form of an equilateral trapezoid, the tooth section is two equilateral transises having the common side, the side faces are a continuation of the other two sides of the trajectory, and the angle of inclination of the side rpami is 33-40.

On (|) I1 1 are shown the GiiycKu LAN. glued but profiled: iia ijjiir. 2 L-ik it :. glued bars before cutting; in FIG. 3 and FIG. 4 shows glued wooden boards or panels assembled from production waste.

The glued wood panel consists of bars 1 and 2 glued together according to a shaped profile made in each bar on the sides. In the specified

the profile of the tooth section is two asymmetric equilateral trapezoid 3 having a common side 4, the side faces 5 and 6 are a continuation of the other two sides of the trapezoid and the angle of inclination of the side face is 35-40. This is the optimal angle of inclination of the side, as with a smaller angle, the material consumption increases, with a larger angle, the strength of the glued parts is lost, because bonding surface is shortened.

The shield is made as follows.

Bars 1 and 2 (this may be production waste - small bars of parallel and transverse profile for the manufacture of panels) (|) pe5epyioT. getting a shaped profile, characterized by a large area of the glued surface. Then the surfaces of the bars are glued and folded in response according to irofp.chyu. ir; glued plates form a block (Fig. 2). The glued bars are glued with paper or glued and a vertical force is applied to them, which makes them glued, because gluing, because with vertical force, bonding occurs one-in-one time. In a similar way, not only wood bars can be glued, but also 1G5 other materials, for example, plastic, etc. The blocks placed in the block can be cut along line 9, for example, for a parquet board.

Depending on what kind of product you need to get, glued bars are stacked in blocks (Fig. 2), form panels or panels from them (Fig. Z. Fig. 4U

Thus, an increase in producer productivity is achieved with iriroTOBJicniiii glue1x 1x wooden panels, and the claimed one has greater strength and bending due to a horizontally glued seam, is less obsolete, and there is an increase in gluing strength and an increase in the strength of the seam on bending at the place of gluing.

Claims (1)

A glued wooden shield, including bars connected to each other along lateral faces in a toothed type, with the lateral sides made oblique and the tooth cross section in the form of an equilateral trapezoid, characterized in that the tooth section is two equilateral trapeziums having a common side, side faces are a continuation of the other two sides of the trapezoid, and the angle of inclination of the side face is 35-40 °.
