Because one end of the masonry unit needs to be connected with the frame column into a whole by adopting the steel bars, the site construction is not convenient. 3. After the masonry unit is damaged by an earthquake, the masonry unit is not convenient to repair quickly.

The advantages of this embodiment are as follows:
the invention has the advantages that:
1. the connecting structure 7 allows the two ends of the wallboard to generate opposite-direction displacement, and can solve the problem that the wallboard is damaged due to the fact that the structure is seriously twisted but the wallboard cannot be twisted in torsion during a large earthquake.
2. The wallboard with the horizontal gap can reduce the external rigidity of the wallboard to a certain degree, when an earthquake occurs, the L-shaped building integrally rotates around an inflection point, a column at the inflection point only rotates in situ, the outer sides of two sides of the L-shaped building are far away from the inflection point column and rotate by taking the inflection point as an axis, the columns at two sides of the wallboard have displacement difference in the direction perpendicular to the wall surface, and the displacement difference of the columns at two sides of the wallboard in the direction perpendicular to the wall surface is compensated by a high-rigidity spring device; the wall body is connected on the post, and the power consumption is reliable with the connection, has avoided the off-plate cantilever structure that probably forms in the wall roof beam is connected.
3. The connecting structure can ensure that the wallboard and the frame column are fixed in normal use; when earthquake occurs, the structure is twisted, but the top end and the bottom end of the wall board can move relative to the frame column left and right and back and forth through the cooperation of the spring and the damper, a new corner is generated between the frame column and the wall board, but the motion is only converted into the motion of front, back, left and right (the motion of the transverse U-shaped frame 71 rotating along with the column and the pushing connecting piece can be generated), at the moment, the hard rubber layer is used for protecting connection, and the stress concentration is prevented
4. Increase 6 direction tolerance values, solved component position and design and have the problem that can't assemble under the inevitable error:
1) and (3) in the y direction: the length of the connecting piece is changed by rotating the internal thread hollow cylinder, the connection is fully abutted against two ends, and by controlling the position of the slotted hole, the main force transmission body (namely the connecting block) is abutted against the transverse U-shaped frame 71 before the outer convex screw 75, and simultaneously 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 with error in the y direction when the column and the wallboard are placed can be ensured;
2) and (3) in the z direction: the transverse U-shaped frame 71 prevents the connecting piece from vertically moving downwards, a gap between the wall plate and the vertical U-shaped frame 73 is slightly larger than the disc abutting seat and the hard rubber layer, the connecting piece is prevented from overturning, the transverse U-shaped frame 71 is higher than the vertical U-shaped frame 73 by a certain numerical value, the connecting piece firstly touches the bottom end of the long slotted hole of the transverse U-shaped frame 71, and in addition, the depth of the long slotted hole and the vertical U-shaped frame 73 is used for preventing the vertical upward separation, so that the assembly with an error in the z direction during the placement of the column and the wall plate can be;

The wall plate 4 is a rectangular wall plate which comprises two L-shaped sub-wall plates 41 with the same size and shape; the two L-shaped wall dividing plates 41 are rotationally and symmetrically arranged by taking the geometric center of the rectangular wall plate as the circle center; the horizontal contact interfaces of the two L-shaped sub-wallboards 41 are positioned at two sides of the wallboard 4, and the damping layers 5 are filled at the horizontal contact interfaces and are connected with each other through the bending deformation energy dissipaters 19 in the plane of the steel plate; the vertical contact interfaces of the two L-shaped wall dividing plates 41 are positioned in the middle of the wall plate 4, impact buffer layers 18 are fixed at the vertical contact interfaces, and flexible fillers 6 are filled between the impact buffer layers 18; the left end and the right end of the L-shaped partition plate 41 are connected with the frame column 1 through the connecting structures 7 respectively; the L-shaped wall dividing plate 41 is connected with the frame column 1 at the middle position of the frame column 1 through a sliding rod connecting structure 70; the slide rod connecting structure 70 uses a slide rod instead of the external screw rod 76, and the rest is the same as the connecting structure 7.
When the two L-shaped wall sub-panels 41 generate small relative displacement in vibration, energy is consumed by the damping layer, when the relative displacement is large, the bending deformation energy dissipater 19 in the plane of the steel plate participates in energy consumption, when the vertical contact interfaces of the two L-shaped wall sub-panels 41 are contacted with each other, the two L-shaped wall sub-panels 41 are contacted through the impact buffer layer 18 to generate impact energy dissipation, the two L-shaped wall sub-panels 41 are prevented from continuously sliding to generate relative displacement, rigid support is formed for the frame beams and the frame columns, and the frame structure is prevented from collapsing.
