The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a timber and bamboo timber connection structure that the cost is lower, the installation is comparatively convenient and mechanical properties can satisfy the requirement again.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides a timber and bamboo timber connection structure, includes timber body and circle bamboo, be provided with the cylindrical connecting portion of a body coupling on the timber body, the direction of height of cylindrical connecting portion with the texture direction of timber body is parallel, the link of circle bamboo embolias cylindrical connecting portion, there is the bamboo internode in the circle bamboo, the lateral wall of cylindrical connecting portion with between the inner wall of circle bamboo and the terminal surface of cylindrical connecting portion with be provided with the cementing layer between the internode of bamboo, the circle bamboo outer wall is located cylindrical connecting portion department cover is equipped with the larynx hoop.
The number of the hose clamp is 2, one hose clamp is positioned at the bottom of the cylindrical connecting part, and the other hose clamp is close to the top of the cylindrical connecting part.
The hose clamp is made of metal.
The diameter ratio of the cylindrical connecting part is 1mm larger than the inner diameter of the round bamboo.
The length of the bamboo inner joint and the end part of the round bamboo is 0-2 mm longer than the height of the cylindrical connecting part.
The material of cementing layer is foaming polyurethane adhesive.
The utility model has the advantages that: the utility model provides a wood and bamboo connection structure, which has lower connection cost; the operation is simple, and the required equipment is simple; the connection strength is far better than the connection of the rattan and the wooden pin.

Fig. 1 is a schematic structural diagram of the wood and bamboo connection structure water of the utility model.
The reference numbers in the figures are as follows: 1-wood body; 2-round bamboo; 3-bamboo inner joint; 4-a hose clamp; 5-a cementing layer; 11-cylindrical connection.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, a timber and bamboo timber connection structure, including timber body 1 and circle bamboo 2, the timber that timber body 1 used is 150mm long 400 mm's pine, and the bamboo timber of circle bamboo 2 is the four-year-old mao bamboo. Be provided with the cylindrical connecting portion 11 of an organic whole connection on timber body 1, the direction of height of cylindrical connecting portion 11 is parallel with the texture direction of timber body 1, highly is 200mm, and the diameter is 94 mm. The connecting end of the round bamboo 2 is sleeved into the cylindrical connecting part 11, the inner bamboo joint 3 is arranged in the round bamboo 2, the outer diameter of the connecting end of the round bamboo 2 is 80mm-120mm, preferably 105mm, the inner diameter is 93mm, the length is 1000mm, and the distance from the inner bamboo joint 3 closest to the connecting end is 201 mm. The length of the bamboo inner joint 3 and the end part of the round bamboo 2 is 0-2 mm longer than the height of the cylindrical connecting part 11, and the length is preferably 1 mm. The diameter of the cylindrical connecting part 11 is 1mm larger than the inner diameter of the round bamboo 2.
Be provided with adhesive joint layer 5 between the lateral wall of cylindrical connecting portion 11 and the inner wall of circle bamboo 2 and between the terminal surface of cylindrical connecting portion 11 and the interior festival 3 of bamboo, adhesive joint layer 5's material is the polyurethane adhesive that foams. The outer wall of the round bamboo 2 is sleeved with a throat hoop 4 at the cylindrical connecting part 11, and the throat hoop 4 is made of metal. The number of the hose clamp 4 is 2, one of the hose clamp is positioned at the bottom of the cylindrical connecting part 11, and the other hose clamp is close to the top of the cylindrical connecting part 11.
The utility model discloses an installation mode does: at first, process out a cylindrical connecting portion on timber body, the direction of height of cylindrical connecting portion is parallel with timber body's texture direction, highly is 200mm, and the diameter of cylindrical connecting portion is 94mm, and the length of the first bamboo inner pitch distance connection end of the joint department of circle bamboo is 1mm higher than the cylindrical connecting portion that timber was reserved. Uniformly gluing the circumferential surface and the end surface of the reprocessed cylindrical connecting part, wherein the used adhesive is a foaming polyurethane adhesive cured at normal temperature; then the moso bamboo is sleeved into the cylindrical connecting part, and then the metal hose clamp is used for anchoring at the connecting end part of the circular bamboo and the position 150mm away from the connecting end part; and (5) obtaining the bamboo-wood connecting member with higher performance after the adhesive is solidified. The timber section is fixed, and the cantilever beam test on the other section of the moso bamboo shows that the bending strength of the method reaches 95.6MPa and reaches 82 percent of the bending strength of the original bamboo material.
