[0015] Figure 1 In [the relevant part], it can be seen from the structural diagram of the column of the present invention that the column is composed of a column body and a column bracket.

[0016] The four corners of the column body are angle steels, and the four angle steels are connected by transverse angle steels to form a column body with a space truss structure; there are positioning pins and through holes on the transverse angle steel at the upper end of the column body, and through holes corresponding to the positioning pins and through holes at the upper end of the column are provided on the transverse angle steel at the lower end of the column body. The function of the positioning pin is to quickly and accurately position when connecting the upper and lower columns; there are through holes for connecting the column bracket on the vertical angle steel of the column body.

[0017] The four transverse angle steels of the column bracket are connected by vertical angle steels to form a space truss. There are conical positioning pins and multiple through holes on the surface where the column bracket is connected to the column body. The positions of the positioning pins and through holes correspond one by one to the positions of the through holes on the column body for connecting the column bracket; the angle formed by the other surface of the column bracket (the surface connected to the beam) and the horizontal plane is an obtuse angle, and there are also through holes and conical positioning pins on this surface.

[0018] In Figure 2 the structural diagram of the beam of the present invention, it can be seen that:

[0019] The four corners along the length direction of the steel beam are four angle steels, which are connected by vertical and transverse angle steels to form a space truss; the two end faces of the beam form an acute angle with the horizontal plane, and this acute angle is complementary to the angle between the inclined plane of the column bracket and the horizontal plane. There are multiple through holes and strip-shaped positioning grooves on the inclined angle steel. The positions of the through holes and the positioning grooves correspond to the positions of the through holes and the positioning pins on the inclined surface of the column bracket; there are multiple groups of through holes on the angle steels on each side of the beam, which are respectively used to fix the floor bracket, wall frame, and roof truss.

[0020] Figure 3 In [the relevant part], it can be seen from the structural diagram of the floor support system of the present invention that the components of the floor support system include the floor main frame, floor secondary frame, floor side frame, and floor bracket.

[0021] The main floor frame and the secondary floor frame are isosceles trapezoidal frames of the same height composed of angle steel, and both of their end faces form an obtuse angle with the horizontal plane. There are through holes and positioning grooves on their surfaces, and their height is less than that of the beam.

[0022] The side floor frame is a right trapezoidal frame composed of angle steel. One of its end faces is the same as one of the end faces of the main floor frame and the secondary floor frame, and the other end face is a right angle. There are only through holes on this surface. The height of the side floor frame is the same as that of the main floor frame and the secondary floor frame.

[0023] The corbel of the floor frame is also a right trapezoidal frame composed of angle steel. One of its end faces forms an acute angle with the horizontal plane, and this acute angle is complementary to the obtuse angle formed by the end face of the main floor frame and the horizontal plane. There are through holes and positioning pins on this surface; the other end face forms a right angle with the horizontal plane, and there are also through holes and positioning pins on this surface. The height of the corbel of the floor frame is the same as that of the main floor frame.

[0024] In Figure 4 the structural diagram of the wall frame of the present invention, it can be seen that the wall frame includes a vertical wall frame, a horizontal wall frame, and a gable wall frame.

[0025] The structures of the vertical wall frame and the horizontal wall frame are both rectangular frames welded by angle steel. The height of the vertical wall frame is determined by the height of the floor, and the width is determined according to the thickness of the building wall; the length of the horizontal wall frame is determined according to the width of the door and window, and its width is determined according to the thickness of the building wall. There are through holes for fixing the wall frame on the upper and lower end faces of the vertical wall frame and the left and right end faces of the horizontal wall frame; when the vertical truss is installed on both sides of the door and window opening, through holes for fixing the horizontal wall frame need to be added on the surface where it contacts the horizontal wall frame.

[0026] The lower part of the gable wall frame is the same as that of the vertical wall frame. After the horizontal angle steel at the upper part rotates a certain angle, it is welded to the vertical angle steel at both ends, and the rotation angle is the same as the angle of the building roof.

[0027] Figure 5 In

[0028] the structural diagram of the roof frame of the present invention, it can be seen that the roof frame includes a side main roof frame, a main roof frame, a secondary roof frame, and a roof edge frame.

[0029] First, the angles at both ends of the main roof frame take different values according to the angle of the building roof, and the angles at both ends are different from each other.

[0030] Second, there are not only through holes but also conical positioning pins on both sides of the main roof frame.

[0031] The difference between the side main roof frame and the main roof frame is that the side main roof frame is a rectangular frame composed of angle steel, and there are through holes and conical positioning pins only on one side, and the rest of the structure is the same as that of the main roof frame.

[0032] The secondary roof truss is a rectangular frame composed of angle steels, and there are through holes and open positioning grooves at both ends in the length direction.

[0033] The cantilever roof truss is a right trapezoidal frame composed of angle steels. There are through holes and positioning pins on the side of the right angle side.

[0034] In Figure 6 In the schematic diagram of the beam-column frame connected by the columns, column brackets and beams of the present invention, it can be seen that the connection nodes of the columns, column brackets and beams are all rigid nodes that can bear shear force, pressure and bending moment. Due to the functions of the positioning pins and positioning grooves, the installation is convenient.

[0035] In Figure 7 In the schematic diagram showing the floor support system connected by the main floor frame, secondary floor frame and floor frame bracket of the present invention, it can be seen that the main floor frame is connected to the beam through the floor frame bracket, the secondary floor frame is connected to the main floor frame through the floor frame bracket, and one side of the floor side frame is connected to the main floor frame through the floor frame bracket and the other side is connected to the beam through bolts. At all the connection points, rigid nodes that can bear shear force, pressure and bending moment are formed, and the installation is convenient.

[0036] In Figure 8 In the schematic diagram of the wall support system connected by the wall frames of the present invention, it can be seen that the vertical wall frames can be conveniently connected between the floor slab and the steel beam by bolts, and the vertical wall frames can also be conveniently combined with the horizontal wall frames to form door frames and window frames.

[0037] In Figure 9 In the schematic diagram of the roof support system and the wall support system at the gable connected by the side main roof truss, main roof truss, secondary roof truss, eaves truss and gable wall truss of the present invention, it can be seen that the connections between the side main roof truss, main roof truss, eaves truss and the beam, the connection between the secondary roof truss and the main roof truss, and the connections between the lower part of the gable wall truss and the beam and the upper part and the main roof truss are all rigid nodes that can bear shear force, pressure and bending moment, and the installation is convenient.

[0038] In Figure 10 In the schematic diagram of installing wooden boards on the overall frame connected by the components of the present invention, it can be seen that the work content is only to fix the cut wooden boards on the frame with screws. Whether it is connecting the components with bolts to form the frame or fixing the wooden boards, they are all simple processes. Whether it is the work efficiency or the requirements for technicians, they are all lower than those using traditional processes. Therefore, the labor cost is much lower than that using traditional processes. It can also be seen from the figure that the wooden boards used for installation are all rectangular boards, which are convenient for processing.

[0039] In Figure 11 It can be seen that only the wooden boards can be seen both inside and outside the completed building, and there is no difference in the internal and external appearances from the wooden structure buildings completed by using traditional processes.
