The present invention will be further explained with reference to the accompanying drawings:

fig. 1 is a schematic elevation view of the overall structure of the embodiment of the present invention.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1, in order to illustrate an embodiment of the present invention, a transition support structure of a shear wall is described, which extends from the first floor of a building to the fourth floor of a frame beam 2, and includes a support pillar 1 used as a main stress member, wherein the support pillar 1 extends from the first floor and is connected with the frame beam 2; one side of the support column 1 is built with a reinforced concrete inclined wall 3 as a secondary stress member. More specifically, the reinforced concrete skew wall 3 is constructed on the side of the support column 1 that is connected to each frame beam 2.

This conversion bearing structure of shear force wall, from the first floor ground of building upwards extend to fourth floor frame roof beam 2 department, utilized the integrated configuration of support column 1 and reinforced concrete skew wall 3, form the transition layer, effectively disperse vertical force and horizontal force, and the power transmission performance is good, the setting of former conversion layer with the conversion roof beam has been avoided, the cost of constructing the main part has been reduced, also avoid the structure bearing capacity to produce the sudden change because of the setting of conversion layer, simultaneously this conversion bearing structure's occupation space is little, the usage space in the building finite space can increase.

In the present embodiment, it is preferable that the reinforced concrete inclined wall 3 extends obliquely upward from the connection of the support column 1 and the second-tier frame beam 2, and the top of the reinforced concrete inclined wall 3 is flush with the top end of the support column 1.
