Specifically, the first guide rail 31 is a combined structure, and is formed by connecting two third C-shaped steels 311 which are arranged back to back through a first connecting piece 4, namely, two cold-formed back-to-back C-shaped steels are attached to the panel 1 and connected through the first connecting piece 4 to form the combined structure, and the second guide rail 32 is a single second U-shaped steel 321 and further is a cold-formed U-shaped steel.
The length of the second guide rail 32 is greater than the length of the first guide rail 31, so that the first guide rail 31 extends to the section of the truss structure 22, which corresponds to a common connecting body being erected on the truss structure 22 and the first guide rail 31, so as to ensure stable connection between the first guide rail 31 and the truss structure 22.
Wherein, two positive and negative two sides of panel 1 are hugged closely respectively to two third C shaped steel 311, and single second U shaped steel 321 is connected at two third C shaped steel 311's lateral surfaces, makes third C shaped steel 311 and second U shaped steel 321 hug closely near the terminal surface of panel 1 in order to form the triangle-shaped structure, has stability because of triangle-shaped equally, consequently can further improve combination guide rail 3's connection stability.

In some embodiments, in order to make the connection between the combination truss column 2 and the combination guide rail 3 and the foundation or the frame beam more firm, the present invention further comprises a support assembly 5, wherein the cross section of the support assembly 5 is in an "L" shape, and the support assembly comprises a first support 51 and a second support 52. Wherein the first support 51 is connected to the truss structure 22 by a third connecting member 53; the second support 52 is connected to the vertical column 21 through a third connecting member 53, and the shear wall is mounted on the foundation or frame beam through each support to prevent the shear wall from being pulled up or causing connection failure.
As shown in fig. 1 and 2, preferably, the width of the second support 52 is smaller than that of the first support 51, so that the second support 52 can be symmetrically installed at both sides of the upright post 21, and the first support 51 is independently installed on the truss structure 22, wherein the second support 52 is also symmetrical with respect to the central axis of the first support 51, so that the connection point of the second support 52 and the first support 51 after being connected with the foundation or the frame beam is approximately an equilateral triangle, thereby stabilizing the connection of the shear wall.

Specifically, the tie plates are respectively connected at the connection of the third link 53 and the first mount 51, and at the connection of the third link 53 and the second mount 52.
The support assembly 5 and the base plate are both made of hot rolled steel plates with the thickness of 3-8 mm, the carbon content of the hot rolled steel plates is slightly higher than that of cold rolled steel plates, and compared with the cold rolled steel plates, the ductility of the hot rolled steel plates is better, and after the hot rolled steel plates are connected with the combined truss upright post 2 and the combined guide rail 3, the combined truss structure can meet the requirement on rigidity and is higher in mobility.
In addition, the height of the support assembly 5 is controlled to be 200-500 mm, and is determined according to the size of the cold-formed C-shaped steel.

In order to enable all mechanical performance indexes of the shear wall to meet requirements, the minimum width of the shear wall is 600 mm. If the thickness exceeds 600mm, the upright bodies 21 are required to be arranged on two sides of the panel 1 and between two oppositely arranged combined truss upright columns 2 or the upright bodies 21 are required to be additionally arranged in the keel frame.
Also, the spacing between the studs 21 on the shear wall should not be greater than 600mm, which is equivalent to not exceeding the minimum width of the shear wall.
In order to enable all mechanical performance indexes of the shear wall to meet requirements, the minimum height of the shear wall is 2400mm, if the minimum height exceeds 2400mm, a first guide rail 31 needs to be arranged on the front surface and the back surface of the panel 1 and between two oppositely arranged combined guide rails 3 or the first guide rail 31 needs to be additionally arranged in a keel frame.
