Abstract

The utility model discloses a hollow glued wooden column with diaphragms, which comprises face plates, side plates and filling materials. The wooden column is characterized in that space is formed between the filling materials. The utility model has the advantages of simple production technique, low cost and price, light weight, cheap transportation, high wood use ratio, high intensity, as well as low possibilities of deformation, cracking and bending.

Description

A kind of hollow tabula veneer type pin

Technical field

The utility model relates to a kind of veneer type pin, more specifically, relates to a kind of hollow tabula veneer type pin.

Background technology

The big pin of tradition adopts solid wood to be made mostly, this pin complex manufacturing technology; The cost height; Price is expensive; Weight is big; The cost of transportation height; Timber waste rate is than higher; Low, the easy deformation of intensity; Cracking, bending.

The utility model content

In order to overcome above-mentioned defective, the utility model provides a kind of hollow tabula veneer type pin, and it comprises front plate, side panel and inserts; It is characterized in that: have the space between the inserts.

As optimized technical scheme of the utility model, wherein said inserts comprises inserts, middle inserts and following inserts.

As optimized technical scheme of the utility model, it comprises two front plate and two side panels of mutual gummed.

As optimized technical scheme of the utility model, wherein two front plate of gummed and the junction of two side panels are an angle of 90 degrees or miter angle mutually.

The utility model also provides the manufacture method of this hollow tabula veneer type pin, and it comprises the steps:

1. a certain thickness monoblock veneer is cut into the gummed lath of four same widths, make four gummed lath width identical;

2. then a skew back of each bar gummed lath of four gummed laths is cut the right angle of inclined-plane at 45 or 90 °; As two front plate and two side panels;

3. make the square veneer of certain width then, it is grown or is wide and is: the thickness of the width of each bar veneer-two veneer, as inserts;

4. then four right angle gummed lath and above square planks of having cut inclined-plane at 45 or 90 ° are glued together it with splicing adhesive, constituting a centre is square veneer, is the gummed lath combining structure of same widths all around;

5. with above adhering components 90 minutes, temperature was controlled at 25 ℃-35 ℃;

6. in bonding four gummed laths are pressurizeed, pressure is 3.5kg/cm ²

7. after 90 minutes, promptly be made into finished product.

The pin that adopts this method to produce can solve the technological deficiency of above existence.Production technology is simple; Cost is low; Price is low; In light weight; Cost of transportation is low; The timber utilization rate height; Intensity is big; Not yielding; Not easy to crack; Not flexible.

Fig. 2 is the stereogram of the hollow tabula veneer type of the utility model pin.

The specific embodiment

As shown in Figure 1, a kind of hollow tabula veneer type pin of the utility model, it comprises 1, two side panel 2 of two front plate and goes up inserts 3, middle inserts 4 and following inserts 5.Wherein two front plate 1 and two side panels 2 glue together mutually, and two front plate 1 of gummed and the junction of two side panels 2 are an angle of 90 degrees (shown in A among Fig. 2) or miter angle (shown in B among Fig. 2) mutually.Last inserts 3, middle inserts 4 and following inserts 5 are filled in the space of two front plate 1 and two side panel 2 compositions with certain clearance.

Concrete manufacture method is as follows:

2. then a skew back of each bar gummed lath of four gummed laths is cut the right angle of inclined-plane at 45 or 90 °; As two front plate 1 and two side panels 2;

3. make the square veneer of certain width then, it is grown or is wide and is: the thickness of the width of each bar veneer-two veneer, as last inserts 3, middle inserts 4, following inserts 5;

4. will cut two front plate 1 in right angle and two side panels 2 of inclined-plane at 45 or 90 ° then, with last inserts 3, middle inserts 4, inserts 5 usefulness splicing adhesives are glued together it down, constituting a centre is square veneer, be the gummed lath combining structure of same widths all around, wherein go up between inserts 3, middle inserts 4 and the following inserts 5 and have certain distance;

6. in bonding two front plate 1 and two side panels 2 are pressurizeed, pressure is 3.5kg/cm ²

7. after 90 minutes, promptly be made into finished product.
