Description

Connecting structure of gypsum wallboard and light wood structure bone stud nail

Technical Field

The utility model relates to the technical field of wooden building structures, in particular to a connecting structure of a gypsum wallboard and a light wood structure bone stud nail.

Background

In a light wood structure house system, when the wall panels are gypsum wallboards, steel nails or threaded nails are mostly used for connection, and domestic and foreign researches show that the lightweight wood structure shear wall is mostly damaged by the gypsum wallboards at the nail connection positions in the local ranges of four corner points of the wallboard under the action of horizontal force; how to improve the structural strength of four corners of the wallboard and improve and optimize the stress of the wallboard under the action of horizontal shear is a subject to be faced at present.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: the utility model provides a connection structure of gypsum wallboard and light-duty timber structure bone post nail to solve present timber structure shear force wall and put the easy quilt in the four corners position, lead to appearing structural defect's problem.

In order to solve the problems, the utility model provides the following technical scheme:

a connecting structure of a gypsum wallboard and a light wood structure bone stud nail; it comprises a bone column and a gypsum wallboard which are made of wood materials; one side end face of the bone column is attached to the edge of the gypsum wallboard, a plurality of layers of carbon fiber cloth are arranged at the joint of the side end face and the gypsum wallboard, and the fastening nails sequentially penetrate through the gypsum wallboard and the carbon fiber cloth and are inserted into the bone column for setting.

Preferably, the carbon fiber cloth is adhered between the gypsum wallboard and the bone column through epoxy resin glue.

Preferably, the number of carbon fiber cloth layers used is 1 to 3.

Preferably, the terminal surface that the bone post pasted with the gypsum wallboard is the striation structure, and the lateral margin of gypsum wallboard is connected in the middle part position of bone post, and the length direction mutually perpendicular of gypsum wallboard and bone post.

Preferably, the end face of the bone column, which is attached to the gypsum wallboard, is of a straight-line structure, the lateral edge of the gypsum wallboard is connected to the lateral edge of the end face of the bone column, and the gypsum wallboard and the bone column are in the same straight line in the length direction.

Preferably, the fastener is retained in the bone post to a depth of no less than twice the thickness of the gypsum wallboard.

The utility model has the beneficial effects that:

the utility model designs a new structure aiming at the problem that the structural defects exist in the connection of the wall board and the bone column nails in the wood structure building, and after the connection performance of the screws and nails is enhanced by adopting carbon fiber cloth between the bone columns and the wall board, the damage of the connection nodes of the gypsum wall board and the wood column nails can be effectively delayed, the bearing capacity and the deformation performance of the nodes are improved, and thus the shear strength and the shear rigidity of the light wood structure shear wall of the gypsum wall board are effectively improved.

Detailed Description

The utility model is further described with reference to the following figures and specific examples:

example 1:

referring to fig. 1, the present embodiment provides a connection structure of a gypsum wallboard and a lightweight wood-structured stud; it comprises a bone column 1 and a gypsum wallboard 2 which are made of wood materials; one side end face of the bone column 1 is attached to the edge of the gypsum wallboard 2, a plurality of layers of carbon fiber cloth 3 are arranged at the joint of the gypsum wallboard 2 and the carbon fiber cloth 3, and the fastening nails 4 sequentially penetrate through the gypsum wallboard 2 and the carbon fiber cloth 3 to be inserted into the bone column 1 for setting. The fastening nail used in the present embodiment is a steel nail, and it is conceivable that the steel nail may be installed by replacing it with a screw nail having a similar structure. In this embodiment, the number of carbon fiber sheets 3 used is 1; the carbon fiber cloth is rectangular with the center of the nail hole, and the side length is 10 times of the nail diameter.

The carbon fiber cloth 3 is adhered between the gypsum wallboard 2 and the bone column 1 through epoxy resin glue.

The terminal surface that bone post 1 and gypsum wallboard 2 pasted mutually is the striation structure, and the middle part position at bone post 1 is connected to the lateral margin of gypsum wallboard 2, and the length direction mutually perpendicular of gypsum wallboard 2 and bone post 1.

The fastening nail 4 is left in the bone column 1 to a depth not less than twice the thickness of the gypsum wallboard 2.

Through the shear strength experiment, compare in conventional striae connection, adopted the bone post and the gypsum wallboard that the screw carries out the rigid coupling simultaneously, the bearing structure of this embodiment can bear the weight of the pressure that has improved 1.3 times than it.

Example 2:

referring to fig. 3, in this embodiment, the end face of the bone pillar 1 attached to the gypsum wallboard 2 is a smooth-grain structure, the side edge of the gypsum wallboard 2 is connected to the side edge of the end face of the bone pillar 1, and the gypsum wallboard 2 and the bone pillar 1 are on the same straight line in the length direction. The other structures are the same as those of embodiment 1, and thus are not described again.

Through the pressurization experiment, compare in conventional along the line connection, adopted the bone post and the gypsum wallboard that the screw carries out the rigid coupling simultaneously, the bearing structure of this embodiment can bear the weight of the pressure than it has improved 1.7 times.
