The teeth on the steel toothed plate 4 are straight teeth, helical teeth or a combination of the straight teeth and the helical teeth.
When the teeth on the steel toothed plate 4 are oblique teeth, the included angle between the teeth and the wood grain is preferably 30-60 degrees; the thickness of the steel toothed plate 4 is preferably 1 to 1.5mm.
The included angle between the inclined teeth on the steel toothed plate 4 and the wood grain is preferably 45 degrees.
The two surfaces of the laminated rubber 1 are respectively connected with the low-density panel 2 and the wood keel 3 in an adhesive way through an interface agent and glue
The low-density panel 2 is an OSB board, a plywood, a low-density fireproof board, a gypsum board, a calcium silicate board and the like.
The wood keel 3 is an SPF imported specification wood, a domestic fast-growing wood specification wood or a poplar LVL wood keel.
The thickness t of the rubber strip in the laminated rubber 1 is 3 mm-10 mm.
The rubber hardness of the laminated rubber 1 is preferably 50 to 100, and the density is preferably 0.50 to 2.00g/cm 3 The tensile elongation is preferably 100 to 200%, and the tensile strength is preferably more than 2.0MPa.

The invention has the beneficial effects that:
compared with the low-density panel with poor nail holding force and low connection rigidity and connection bearing capacity, the novel connection of the wood keel and the panel slows down the stress concentration of the traditional nail connection, increases the stress area, ensures that the stress is more uniform, and improves the rigidity and the bearing capacity of the connection of the low-density panel and the wood keel. The rigidity and the bearing capacity of the wall body adopting the connection are improved.
The connection mode of the panel and the wood keel is beneficial to the industrialized assembly production of the wallboard and meets the industrialized requirement of buildings. Meanwhile, the vibration isolation capability of the connection and the wall body can be improved by laminating the rubber layers.

Detailed Description
The invention is further described below with reference to the figures and examples.
As shown in fig. 1-2.
The utility model provides a coincide rubber connection structure of wood joist and panel, it mainly comprises low density panel 2, coincide rubber 1 and wood joist 3, as shown in figure 1, coincide rubber 1's shape and wood joist 3 phase-match, coincide rubber 1's two sides respectively through interfacial agent, glue and low density panel 2 and the glued continuous of wood joist 3, press from both sides in the coincide rubber 1 and be equipped with the steel toothed plate 4, the thickness of steel toothed plate 4 between 1 ~ 1.5mm, the tooth of whole stamping forming can be two-sided straight-tooth, two-sided skewed tooth or arbitrary combination on it, be the combination tooth in figure 2, the contained angle of skewed tooth and timber with the line is between 30-60 degrees, preferred contained angle is 45 degrees. The steel teeth on the steel toothed plate 4 penetrate through the rubber strips to be respectively occluded with the panel and the wood keel, so that the initial rigidity, the shearing resistance and the energy consumption capacity which are only connected by the rubber strips are greatly increased.
