Abstract

The utility model discloses a dual-dovetail joint, which relates to a wood working connection tenon. To solve the problem that adjacent wall bodies of the composition wood buildings in prior art have no special connectors, the utility model provides a dual-dovetail joint, which has the advantages of a stable splicing location and a good integral smoothness. The section shape of the tenon body (1) of the utility model is a dual-dovetail shape with No. 1 dovetail (1-1) and No. 2 dovetail (1-2) connected with each other. The utility model can be applied in the connection of outer wall bodies as well as the connection of an outer wall body and an inner middle wall. During the installation, the dual-dovetail joint is inserted into the mounting groove of the wall body; through the friction between the dual-dovetail joint and the inclined plane cooperating with the mounting groove, a stable connection of adjacent wall bodies can be realized and no connectors can be seen after the connection. With a strong splicing bite force, the utility model makes the installation of wood buildings more convenient, thus greatly saving manual working time, improving efficiency and thereby reducing labor costs. The utility model is nail-free, glue-free, keel-free in construction and easy to disassemble for repair and displacement, the application prospect is broad.

Description

Two dovetails

Technical field

The utility model relates to a kind of carpenter's connection tenon.

Background technology

Wooden frame structure is from heavy and light, and based process is easy, and anti-differential settlement is very capable, is applicable to most of geological conditions, and its weight per unit area only is equivalent to the 1/4--1/3 with homalographic brick mix structure weight.In China's living standards of the people, today that cultural taste improves day by day, timber is with a kind of natural health and material attitude that have compatibility, makes the healthy residence that wooden frame structure has great advantage as a kind of tool, by many people are understood and accept.But also do not have a kind of special connecting piece existing the composition between the wooden frame structure neighboring walls.

The utility model content

For solving the existing problem that does not also have a kind of special connecting piece between the wooden frame structure neighboring walls of forming, the utility model provides a kind of pair of dovetail, and it has the advantage that the splicing location is firm, integral smoothness is good.The cross sectional shape of the tenon body of the present utility model double-swallow-tail shapes that to be swallow-tail form be connected relatively with No. two swallow-tail forms.The utility model can be applicable to the connection between the outer body of wall, also can be applicable to be connected (as shown in Figure 2) between outer body of wall and the interior division wall, during use, adjacent two bodies of wall have dovetail groove at joint, the cross sectional shape of the mounting groove that the butt joint back forms and the cross sectional shape of described in the utility model pair of dovetail match, only need during installation two dovetails are inserted in the mounting groove of body of wall, rely on the frictional force between two dovetails and the inclined-plane that mounting groove matches, can realize the firm connection between the neighboring walls, can't see connector after the connection, snap-in force is strong during splicing, make that the installation of wooden frame structure is more convenient, can save the artificial time greatly and raise the efficiency, and then minimizing labor cost, when having construction, it exempts from nail, exempt from glue, exempt from keel, advantage such as be convenient to overhaul and divert from one use to another, have a extensive future.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is user mode figure of the present utility model, and Fig. 3 is the A-A sectional drawing of Fig. 1.

The specific embodiment

The specific embodiment one: (referring to the cross sectional shape of the tenon body 1 of present embodiment of Fig. 1-Fig. 3) double-swallow-tail shapes that to be swallow-tail form 1-1 be connected relatively with No. two swallow-tail form 1-2.

The specific embodiment two: (be that referring to the difference of the present embodiment of Fig. 1-Fig. 3) and the specific embodiment one a described swallow-tail form 1-1 and No. two swallow-tail form 1-2 are symmetrical along center line 2.Other composition is identical with the specific embodiment one with annexation.Therefore the described swallow-tail form 1-1 of present embodiment and No. two swallow-tail form 1-2 are symmetrical along center line 2, need not to consider the installation direction of two dovetails in use, can guarantee product quality, can enhance productivity again.

Claims

1, two dovetails, the cross sectional shape that it is characterized in that tenon body (1) double-swallow-tail shape that to be a swallow-tail form (1-1) be connected relatively with No. two swallow-tail forms (1-2).

2, according to claim 1 pair of dovetail is characterized in that a described swallow-tail form (1-1) and No. two swallow-tail forms (1-2) are symmetrical along center line (2).
