In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an assembled square steel pipe steel wood combination cross node, includes the square tube body, all be provided with connecting elements on every angle at four angles of square tube body respectively, the square tube is connected respectively on the edge of a wing about the connecting elements on every angle, and connecting elements on every angle pass through the bolt and are connected with the square tube in proper order, and square tube is internal to have a style of calligraphy fixed plate and two L type fixed plates put, and a style of calligraphy fixed plate and two L type fixed plates pass through bolted connection and constitute cross component, a style of calligraphy fixed plate insert in the square tube with the cross component that L type fixed plate is constituteed.

As a further technical solution of the present invention: the square pipe body is of a square hollow body structure.

As a further technical solution of the present invention: the L-shaped fixing plate is provided with two rows of bolt holes for connecting the square timber and the connecting component.

As a further technical solution of the present invention: the straight-line-shaped fixing plate is provided with two rows of bolt holes used for being connected with the square timber and the connecting component.

As a further technical solution of the present invention: the connecting component is provided with a plurality of rows of bolt holes for being connected with the cross-shaped component.

Compared with the prior art, the beneficial effects of the utility model are that: 1) the connection between the square pipe body, the square timber and the connecting member is a simpler connection mode, so that the cross-shaped node member provides constraint force under the conditions of external force and self gravity. 2) A cross-shaped member consisting of the straight-line-shaped fixing plate and the L-shaped fixing plate in the square pipe body is inserted into the square wood, so that the shearing resistance of the cross-shaped node member is improved. 3) The bolts used for connecting the components are high-strength bolts, which can meet the bearing capacity of the node and resist the shear stress deformation. And moreover, consumable materials are reduced, field welding is avoided, the construction speed is accelerated, national advocation and call are responded, and the environment-friendly energy-saving building is met.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1: referring to fig. 1-8, an assembled square steel tube and wood combined cross node comprises a square tube body 1, wherein the square tube body 1 is of a square hollow body structure, a connecting member 3 is arranged at each of four corners of the square tube body 1, left and right flanges of the connecting member 3 at each corner are respectively connected with a square wood 2, and the connecting member 3 at each corner is sequentially connected with the square wood 2 through bolts.

Referring to fig. 5, a cross-shaped member is built in the square pipe body 1, which is formed by connecting a straight fixing plate 6 and two L-shaped fixing plates 5 by bolts 4.

Example 2: in addition to embodiment 1, referring to fig. 6 and 7, the cross-shaped member formed by the straight-line fixing plate 6 and the L-shaped fixing plate 5 is inserted into the square timber 2, and each of the straight-line fixing plate 6 and the L-shaped fixing plate 5 has two rows of bolt holes for connecting with the square timber 2 and the connecting member 3.

The utility model discloses a theory of operation:
