Description

Tenon fourth of twelve earthly branches structure spare

Technical Field

The utility model belongs to the technical field of the carpenter's component, concretely relates to mortise and tenon joint structural member.

Background

The ancient Chinese building is constructed by main components such as upright posts, cross beams, purlins and the like in a structural mode that timber and tiles are used as main building materials and a timber frame structure is mainly in a tenon-and-mortise structure, and joints among the components are matched in tenon-and-mortise to form an elastic frame.

The tenon-and-mortise work is an extremely exquisite invention, and the connection mode of the components enables the traditional Chinese wood structure to become a special flexible structure body exceeding a bent, a frame or a steel frame of a modern building, so that the traditional Chinese wood structure not only can bear larger load, but also allows certain deformation to be generated, certain seismic energy is offset through deformation under seismic load, and the seismic response of the structure is reduced.

However, in the existing woodworking operation, the mortise and tenon structure is gradually replaced by connecting modes such as screws and viscose, so that dangers such as formaldehyde exist in the processed furniture or home, or a large number of screws are consumed, and the stability of screw connection is not high.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model lies in providing a mortise and tenon joint structure spare, can need not the foreign object and can stably connect, harm is little.

In order to solve the problem, the utility model provides a mortise and tenon joint structure spare, including first member and second member, be equipped with the tongue-and-groove on the first member, the second member includes first portion and second portion, the one end of first portion with the mutual interlock of one end of second portion, interlock department card is established in the tongue-and-groove.

Preferably, the end surfaces of the first and second parts which engage are provided as inclined surfaces.

Preferably, the inclined planes are concave-convex, and the concave-convex shapes of the two inclined planes are correspondingly matched.

Preferably, the second rod piece is provided with a pin hole in the vertical direction at the occlusion part of the first part and the second part; the mortise and tenon structure piece further comprises a wood pin, and the wood pin is inserted into the pin hole.

Preferably, the mortise is provided on an end surface of the first bar.

The utility model provides a mortise and tenon joint structure spare adopts the interlock to constitute the member through the tongue-and-groove and carries out mortise and tenon joint for three wooden fitting can stabilize the connection, need not to adopt screw or viscose, and harm is little.

Drawings

Fig. 1 is the utility model discloses tenon fourth of twelve earthly branches structure spare structural diagram.

The reference numerals are represented as:

1. a first bar member; 11. mortises; 2. a second bar member; 21. a first portion; 22. a second portion; 23. a pin hole.

Detailed Description

Referring to fig. 1 in combination, according to an embodiment of the present invention, a mortise and tenon structure includes a first rod 1 and a second rod 2, a mortise 11 is disposed on the first rod 1, the second rod 2 includes a first portion 21 and a second portion 22, one end of the first portion 21 and one end of the second portion 22 are engaged with each other, and the engaged portion is clamped in the mortise 11.

This embodiment product is to carrying out mortise and tenon joint to three straight-bar, sets up tongue-and-groove 11 on first member piece 1, two parts in addition: one end of each of the first part 21 and the second part 22 is occluded to form the second rod member 2, the occluded part is inserted into the mortise 11, so that the three parts are completely connected, stable mortise-tenon connection can be formed under the condition of not using screws or adhesive action, and the structure is stable.

In order to improve the stability of the second rod 2 at the occlusion part and the stability of the mortise and tenon connection between the occlusion part and the mortise 11, the end surfaces of the first part 21 and the second part 22 which are occluded are inclined surfaces, so that the contact area of the two parts is increased. In particular, the inclined surfaces are concave-convex, and the concave-convex shapes of the two inclined surfaces are correspondingly matched, so that the first part 21 and the second part 22 are prevented from slipping off and separating along the direction of the inclined surfaces.

The second rod 2 is provided with a pin hole 23 in the vertical direction at the joint of the first part 21 and the second part 22; the mortise and tenon structure piece further comprises a wood pin, and the wood pin is inserted into the pin hole 23. To further increase the stability of the connection between the first portion 21 and the second portion 22, a conventional wood pin and pin hole 23 is used for positioning and connecting, and is arranged at the engagement position of the two.

In order to form a T-shaped structure, the mortise 11 is formed on the end surface of the first rod member 1, so that the three components form a T-shaped structure, and the structure is stable.

It is easily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
