The advantages of this embodiment are as follows:
the invention has the advantages that:
1. the connection structure 7 allows the two ends of the wallboard to generate opposite displacement, so that the problem that the wallboard is damaged due to the fact that the wallboard cannot resist torsion when the structure is severely twisted during a large earthquake can be solved.
2. The wallboard with the horizontal gap can reduce the external rigidity of the wallboard surface to a certain extent, the L-shaped building integrally rotates around an inflection point in the earthquake, the pillars at the inflection point are only rotated in situ, the outer sides of the two sides are far away from the inflection point pillars, the inflection point is taken as an axis for rotation, at the moment, displacement differences exist in the directions of the pillars at the two sides of the wallboard, which are vertical to the wall surface, and at the moment, the displacement differences of the pillars at the two sides, which are vertical to the wall surface, are compensated through the high-rigidity spring device, so that the wallboard is prevented from being twisted and damaged; the wall body is connected to the column, so that energy consumption and connection are reliable, and an out-of-plane cantilever structure possibly formed in wall beam connection is avoided.
3. The wallboard and the frame column are fixed by the connecting structure, so that the wallboard can be used at ordinary times; during an earthquake, the structure is twisted, but the top end and the bottom end of the wallboard can relatively move left and right and back and forth with the frame column through the cooperation of the springs and the dampers, a new corner can be generated between the frame column and the wallboard, but the new corner is converted into the front, back and left and right movement (the transverse U-shaped frame 71 possibly rotates along with the column and pushes the connecting piece to move), and at the moment, the hard rubber layer is used for protecting connection and preventing stress concentration
4. Increase 6 direction tolerance values, solve the problem that the component position and design have unable assembly under the inevitable error:
1) y direction: the length of the connecting piece is changed through rotation of the internally threaded hollow cylinder, so that the connecting piece fully props against two ends, and the main force transmission body (namely the connecting block) props against the transverse U-shaped frame 71 before the outer convex screw rod 75 by controlling the position of the long groove, and meanwhile, the distance between the two L-shaped angle steels is larger than the diameter of the disc, so that the connecting piece is fully contacted with the wallboard, and the assembly of the column and the wallboard in the y direction under error can be ensured when the column and the wallboard are placed;
2) And z direction: the transverse U-shaped frame 71 prevents the connecting piece from vertically displacing downwards, the gap between the wallboard and the vertical U-shaped frame 73 is slightly larger than the disc abutment and the hard rubber layer, the connecting piece is prevented from overturning, the elevation of the transverse U-shaped frame 71 is higher than that of the vertical U-shaped frame 73 by a certain value, the connecting piece firstly touches the bottom end of a long slot hole of the transverse U-shaped frame 71, in addition, the vertical upward falling is prevented through the depth of the long slot hole and the vertical U-shaped frame 73, and the assembly of the column and the wallboard in the presence of errors in the z direction can be ensured when the column and the wallboard are placed;
3) And the x direction is as follows: the externally-threaded rod 76 can be just placed in the vertical U-shaped frame 73, the steel sheet interval of the vertical U-shaped frame 73 is larger than the width of the semi-cylinder, so that a connecting piece can be placed in the vertical U-shaped frame 73, and then the vertical U-shaped frame 73 with a long slot hole is clamped by screwing the bolt of the externally-threaded rod 75 to limit the x-direction displacement, so that the assembly of the column and the wallboard in the x-direction under error can be ensured when the column and the wallboard are placed;

Example 2
On the basis of example 1, in order to further increase the earthquake-resistant finishing of the wallboard, the following modifications were made: flexible filler 6 is filled between the wall panel 4 and the frame beams and frame columns.
The wall plate 4 is a rectangular wall plate, and the rectangular wall plate comprises two L-shaped partition wall plates 41 with the same size and shape; the two L-shaped partition boards 41 are rotationally symmetrically arranged by taking the geometric center of the rectangular wall board as the center of a circle; the horizontal contact interfaces of the two L-shaped partition boards 41 are positioned at two sides of the wall board 4, and the damping layers 5 are filled at the horizontal contact interfaces and are connected with each other through the bending deformation energy dissipater 19 in the plane of the steel plate; the vertical contact interface of the two L-shaped partition boards 41 is positioned in the middle of the wall board 4, impact buffer layers 18 are fixed at the vertical contact interface, and flexible filler 6 is filled between the impact buffer layers 18; the left end and the right end of the L-shaped partition plate 41 are respectively connected with the frame column 1 through the connecting structure 7; the L-shaped partition wall plate 41 is connected with the frame column 1 at the middle position of the frame column 1 through a slide bar connecting structure 70; the sliding rod connecting structure 70 uses a sliding rod to replace the external threaded rod 76, and the rest is the same as the connecting structure 7.
When the two L-shaped wall-dividing plates 41 generate small relative displacement in vibration, the damping layer 5 is used for dissipating energy, when the relative displacement is large, the steel plate in-plane bending deformation energy dissipater 19 participates in dissipating energy, when the vertical contact interfaces of the two L-shaped wall-dividing plates 41 are contacted with each other, the impact buffer layer 18 is used for contacting, impact energy dissipation is generated, the two L-shaped wall-dividing plates 41 are prevented from sliding with each other to generate relative displacement, rigid support is formed for the frame beam and the frame column, and collapse of the frame structure is prevented.
The steel plate in-plane bending deformation energy dissipater 19 comprises a bending energy dissipation steel plate 53, wherein the top of the bending energy dissipation steel plate 53 is fixedly connected with the L-shaped partition plate 41 above, and the bottom of the bending energy dissipation steel plate is movably riveted with the L-shaped partition plate 41 below in a vertical sliding manner;
a fixing plate 52 is fixedly connected to the upper L-shaped partition plate 41 through a first pre-buried T-shaped plate 51, and a circular fixing hole is formed in the fixing plate 52; the lower L-shaped partition plate 41 is fixedly connected with a sliding plate 55 through a second embedded T-shaped plate 54, a vertical sliding groove 56 is formed in the sliding plate 55, the top of the bent energy consumption steel plate 53 is fixedly connected with a circular fixing hole through a bolt 57, and the bottom of the bent energy consumption steel plate is movably riveted with the vertical sliding groove 56 through a pin 58. The tops of the plurality of the bending energy consumption steel plates 53 are integrally connected and formed through a connecting plate 59.
A vertically arranged long slot 510 is formed in the middle of the bent energy consumption steel plate 53.
When the in-plane bending deformation energy dissipater 19 of the steel plate is stressed, as shown in fig. 9, the upper L-shaped partition wall plate 41 and the lower L-shaped partition wall plate 41 are horizontally displaced, the bending side of the bending energy dissipation steel plate 53 is deformed at this time, the left and right sides of the bending energy dissipation steel plate 53 are repeatedly plastically deformed to be longer under the action of medium and large shock, and the vertical chute 56 is used for providing a sliding allowance when being longer.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions will now occur to those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered to be within the scope of the present invention.
