In view of the above-described deficiencies or inadequacies in the prior art, it would be desirable to provide a wood hybrid structure.

According to the technical scheme provided by the embodiment of the application, the wood mixed structure comprises a building lower portion concrete structure, a building upper portion concrete cylinder and a building upper portion wood structure frame, wherein the building upper portion concrete cylinder is arranged above the building lower portion concrete structure, and the building upper portion wood structure frame is arranged between the building upper portion concrete cylinders.

The utility model discloses in, building lower part concrete structure is concrete frame and shear force wall.

The utility model discloses in, building upper portion concrete barrel is a plurality of concrete barrel, be equipped with between the concrete barrel building upper portion timber structure frame.

The utility model discloses in, building upper portion timber structure frame is pure timber structure frame.

The utility model discloses in, the fire prevention plastic layer is made for macromolecular material.

In the utility model, the aluminum alloy layer is 30 with the perpendicular line⁰The contained angle, the fire prevention plastic layer with be equipped with the sawtooth that suits between the aluminum alloy layer.

To sum up, the beneficial effect of this application: the building height is higher due to the breakthrough of the building height; the building layout is flexible, and the requirements of more building functions can be met; the building plane shape is flexibly arranged, and the building plane shape can be suitable for building sites with various shapes.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, the wood-concrete composite structure comprises a building lower concrete structure 1, building upper concrete cylinders 2 and a building upper wood structure frame 3, wherein the building upper concrete cylinders 2 are arranged above the building lower concrete structure 1, and the building upper wood structure frame 3 is arranged between the building upper concrete cylinders 2.
