In conclusion, the assembled expanded stone wall body is provided with the fixed-size mortise and tenon joints at the periphery, the tenon joints are basically tightly connected after being inserted into the mortise, the function of resisting various complex stresses by the mortise and tenon joints is fully exerted, and the integrity of the combined wall body is improved. Simultaneously establish four steel pin locks in wallboard bottom, pin lock length is high with the tenon, and the wallboard top is equipped with the pinhole, and the depth is 30mm, and the internal filling is full of structural adhesive, and after the wallboard is taken one's place, the pin lock inserts in the pinhole, will have a large amount of structural adhesive to spill over, forms the adhesive surface. The strength of the fabricated expanded stone wall depends on the strength grade of the standard board or panel and mortar. The assembled expanded stone wall body does not need mortar, and the adhesive force of mortise and tenon joints, pin locks and structural adhesive is used for replacing the mortar. Experiments show that the fabricated expanded stone wall body improves the ductility and deformability of the wall body, and the triple connection enables the single plates to form an integral combined wall to form a unit combination body.
Structural connection of assembled expanded stone wall body-connection of assembled expanded stone wall body and upper and lower floor slabs of building
The upper surface of the building lower floor is provided with square steel matched with the panel, and the square steel is inserted into a mortice at the bottom of the panel, as shown in fig. 10. Two opposite vertical sides which are adjacently arranged are positioned between the upper floor slab and the lower floor slab of the building, and a U-shaped clamping groove is arranged at the joint of the two vertical sides and the assembled expanded stone wall body, as shown in figure 9.
Seismic force is a complex stress, and any fixed mode cannot control the seismic force. However, the deformation of any building or structure is not changed, and all members constituting the building are deformed in different forms along with the deformation of the main body structure under the action of earthquake force. The assembled expanded stone wall body is not exceptional. The overall safety of the partition wall is evaluated, so that the safety of the wall in a plane is guaranteed, and meanwhile, the safety under the action of plane external force is guaranteed. In order to improve the safety of the assembled expanded stone wall, a separated connecting layer is arranged between the upper floor slab and the lower floor slab of the building and the assembled expanded stone wall, and the earthquake force is transmitted through the connecting layer. When the building is bent and deformed, the assembled expanded stone wall body can also be bent and deformed in the plane. The U-shaped clamping groove and the square steel pipe form a sliding surface between the building and the assembled expanded stone wall body, so that a part of earthquake energy can be converted into friction energy, and the effect of earthquake force on the combined wall is reduced. The earthquake force acts on the plane external force of the assembled expanded stone wall body, the assembled expanded stone wall body is deformed through the transmission of the U-shaped clamping groove flange deformation of the connecting layer and the micro-deformation force of the square steel tube, and the deformation has certain hysteresis, the hysteresis reduces the force, so that the force acting on the plane external force of the assembled expanded stone wall body is reduced, and the safety of the assembled expanded stone wall body is greatly improved.
(III) the method of connection in the fabricated expansion Dan Qiangban of this embodiment is different from any other method of connection of wall panels and blocks. The connection method in the embodiment not only meets the overall stable safety requirement of normal (static) use, but also meets the overall stable safety requirement of (dynamic) use under the action of earthquake force.
The earthquake disaster shows that under the action of the earthquake force, the inner wall is damaged to a large extent, so that the vertical component of the main body structure is often damaged to a certain extent, but the influence on the horizontal component is smaller, so that the top gap (the width is less than or equal to 30 mm) of the assembled expanded stone wallboard is twisted by high-strength dry hard mortar and is rigidly connected.
As is well known in the art: the overall stability of a wall has a direct relationship to the boundary conditions of the wall. Because the top of the fabricated expanded stone wallboard is a rigid boundary, the two vertical sides are connected by the clamping grooves, which can be regarded as a hinge boundary with certain constraint, and the inside of the mortises at the bottom of the lower panel is provided with 30x3 square steel pipes, which is equivalent to the arrangement of a shear key at the bottom of the fabricated expanded stone wallboard, and the two ends of the square steel pipes are connected with the clamping grooves, which can be regarded as a flexible hinge support. The connection method is safe and reliable in normal use (static state), and the overall stability of the wall can be fully ensured.
When a earthquake disaster occurs, in order to ensure the overall stability and safety of the assembled expanded Dan Qiangban, a connecting method of sliding friction and dynamic hysteresis is adopted, and meanwhile, the integral connecting function of the assembled expanded wallboard is exerted, so that the safety of the assembled expanded wallboard is ensured.

Example 2
The method for assembling and installing the assembled bulge Dan Qiangban in the embodiment comprises the following steps:
s1, paving a leveling layer, a leveling layer and installing a panel
Firstly, cleaning the surface layer of the upper surface of a lower floor of a building to be installed with an assembled expanded stone wallboard;
then, paving a cement mortar leveling layer;
then, paving a polymer mortar leveling bonding layer on the basis of the leveling layer, fixing a square steel pipe, and simultaneously arranging U-shaped clamping grooves on opposite and adjacently arranged vertical sides of the building;
finally, clamping the panel on the square steel pipe, and connecting the panel with a polymer mortar leveling bonding layer;
s2, assembling the standard plate
According to the rule that the plates in the upper and lower adjacent rows of the assembled expanded stone wallboard are arranged in a delta shape, assembling a standard plate and a panel, and assembling the standard plate and the standard plate until the gap between the top of the standard plate at the topmost layer and the floor slab on the building is smaller than 30 mm;
s3, rigid structure of top
And twisting the gaps with dry and hard mortar to finish the rigid connection between the lower bottom surface of the upper floor slab of the building and the assembled bulge Dan Qiangban and finish the combined installation of the assembled bulge Dan Qiangban.
More detailed explanation:
when installing a panel m connected with the vertical side of a building, connecting the panel m with a U-shaped clamping groove corresponding to the panel m; when the standard plate n connected with the vertical side surface of the building is installed, the standard plate n is connected with the U-shaped clamping groove corresponding to the standard plate n.
Secondly, setting the height of the standard plate as H, and setting the distance between the upper floor slab of the building and the top surface of the assembled expanded stone wallboard close to the upper floor slab as H; when H is more than 30mm and less than H, cutting the top of the standard plate, ensuring that H is less than or equal to 30mm, and installing the cut standard plate on the top surface of the assembled bulge Dan Qiangban.
And thirdly, in order to realize the wet-free operation of the whole assembly process of the assembled expanded Dan Qiangban in the whole assembly process, the self structural characteristics of the assembled expanded stone wallboard are fully exerted. The higher the mortise and tenon precision is, the tighter the contact surface is, and the better the stress performance is. Mortise and tenon joint is a connecting mode of combining concave-convex parts. The mortise and tenon joint is structurally provided with a joint, so that twisting under the action of multidirectional force can be resisted, and meanwhile, the mortise and tenon joint is integrated into a whole, so that the flatness of the surface of the assembled expanded stone wallboard is positioned and controlled. Four steel pin locks are arranged on each standard plate, so that the integral bending resistance of the standard plate and the shearing resistance of plate joints can be improved. Meanwhile, four pin holes are formed in the top surface of each wallboard, structural adhesive is filled before installation, pins are inserted into the holes, the adhesive overflows, and the overflowed adhesive forms an adhesive joint surface with the length of about 30mm at the joint of each standard board, so that the tensile and shearing resistance of the joint is improved. The triple connection ensures the overall stability of the combined wall body under the normal use (static state) and earthquake action (dynamic state).
(IV) in order to ensure the horizontal precision of the assembled expanded stone wallboard, the method of double cushion layers is adopted in the embodiment, and specifically comprises the following steps: and cleaning the surface layer of the upper surface of the lower floor of the building to be provided with the assembled expanded stone wallboard, and paving a 20-thickness cement mortar leveling layer. And paving a 5-thickness polymer mortar leveling bonding layer on the basis of the leveling layer, and fixing the 30X3.0 square steel pipe. And finally, the panel which is 200-height and is provided with the third mortises at the top and the bottom is firmly clamped with the square steel pipe to serve as a horizontal base layer. The leveling, leveling and positioning combination lays a foundation with higher horizontal precision for the combined wall.
The flatness of the vertical building component is better than that of the horizontal component, in order to further ensure the vertical precision of the assembled expansion Dan Qiangban, a U-shaped clamping groove is formed in the intersection of the building and the end head of the assembled expansion stone wallboard, the clamping groove is connected with the vertical side face of the building through an expansion bolt, if the surface of the vertical side face of the building is uneven, polymer mortar is used for scraping, the flatness of the U-shaped clamping groove is utilized to ensure the verticality of the assembled expansion Dan Qiangban, and the clamping groove is a vertical high-precision base layer of the assembled expansion stone wallboard.
The horizontal and vertical base layers are important parts of the wall body and are important conditions for ensuring the flatness of the assembled bulge Dan Qiangban. On the basis, the leveling and positioning functions of the pin locks, the pin holes and the mortise and tenon joints of the standard plates are fully exerted, and the surface flatness of the assembled expanded stone wallboard can reach the precision of advanced plastering, namely the standard of horizontal and vertical.
And fifthly, firstly, designing a cloth plate of the assembled combined wall before installation, and completing the cutting of the basic plate type in a factory, and assembling on site to realize toolization in the whole assembly process. The assembly process comprises three steps, namely laying a leveling layer and a leveling layer in the first step. The "U-shaped clamping groove" and square steel tube are placed and fixed while the panel is in place. And (5) after the test is qualified. And the second step is to carry out the integral assembly of the wall body, and the third step is to rigidly connect the assembled combined wall with the floor slab on the building. The installation process has no wet operation, and besides the structural adhesive is injected into the pin holes at the bottom of the standard plate, the actual assembly process is a process of moving the wallboard and re-stacking according to the positioning requirement. Generally, 80 clay bricks can be stacked in an hour, about 800 clay bricks can be stacked in a single shift, and 8000 machine-made clay bricks can be built in the same day. 2000-2500 bricks are built by a rated technical skilled brickwork, and only 1000-12000 bricks are built by a single-sided small wall per class. The new technology and new construction method of the machine-made clay can improve the efficacy by 4-8 times, and the flatness of the wall surface can reach the advanced plastering standard by tenon and hole placement and assembly.
By adopting the technical scheme disclosed by the invention, the following beneficial effects are obtained:
