On the other hand, because the wall blocks can be disassembled and assembled, the connecting parts of the wall blocks are taken as stress concentration positions, and the connecting structure between the wall blocks plays an extremely important role in improving the safety performance of the building. The wall blocks of the existing fabricated building are usually connected by bolts and screws or cast by concrete into a whole at splicing seams. The schemes are rigid connection, when disasters such as earthquake happen, stress can not be effectively released at the connection part, so that the wall body deforms, and even the wall block is damaged and collapsed in serious cases, so that huge potential safety hazards are buried.

Detailed Description
Referring to fig. 1 to 5, the high-efficiency construction method of the high-strength assembly type building includes the assembly of the prefabricated wall block 10 and the wall block 10, and specifically includes the following steps:
processing a steel bar keel 40 for the prefabricated wall block 10, arranging a first steel bar 20 extending to one side of the width direction of the wall block 10 side by side on the steel bar keel 40, and extending a plurality of second steel bars 30 to the opposite side by side, wherein the positions of the first steel bar 20 and the second steel bar 30 are staggered, and the horizontal positions are respectively separated from the center of the thickness of the wall block 20, so that a hook-shaped opposite structure is formed after subsequent bending;
pouring concrete outside the steel bar keel 40 in a mold, so that the first steel bars 20 and the second steel bars 30 extend out of holes in the mold, and grooves are preset at the second steel bars 30, and gaps 60 are formed at the top ends of the grooves in the concrete;
after the concrete is hardened, the first reinforcing steel bars 20 and the second reinforcing steel bars 30 are respectively bent oppositely to form acute angles of 30-60 degrees to form first hook-shaped reinforcing steel bars 20 and second hook-shaped reinforcing steel bars 30, and vertical reinforcing steel bars 21 and 31 are respectively welded near hook-shaped roots;
arranging the prefabricated wall blocks 10 on a building, enabling the first hook-shaped reinforcing steel bars 20 and the second hook-shaped reinforcing steel bars 30 of the adjacent wall blocks to be opposite and then oppositely closed, enabling the free ends of the first hook-shaped reinforcing steel bars 20 and the second hook-shaped reinforcing steel bars 30 to be respectively blocked by the vertical reinforcing steel bars 31 and 21, enabling the free ends to pass through the vertical reinforcing steel bars 31 and 21 after elastic deformation, enabling the free ends to be non-return by the vertical reinforcing steel bars 31 and 21 to form 'mutual' shape matching, and then closing and aligning the adjacent wall blocks 10; concrete or filler is poured into the groove from the notch 60 on the groove for filling.
Accordingly, in the wall block 10, which is a core component of the resulting structure of the prefabricated building, the wall block 10 has a plate shape, the plate surface of the wall block 10 has a square shape, the wall block 10 is formed by casting concrete, and the reinforcement cage 40 is provided inside the concrete. As shown in fig. 1 and 2, a plurality of first hook-shaped reinforcing bars 20 are extended from the right side of the wall block 10 side by side, a plurality of second hook-shaped reinforcing bars 30 are extended from the left side of the wall block side by side, the first and second hook- shaped reinforcing bars 20 and 30 are respectively welded or tied with the reinforcing steel keels 40 into a whole, and are prefabricated together, the hook-shaped reinforcing bars are straight during normal processing, so that the prefabrication processing is convenient, and the reinforcing bars are bent into the hook-shaped reinforcing bars after the concrete is hardened.
The cantilevered ends of the first and second hook- shaped reinforcing bars 20, 30 are horizontally opposed as shown in fig. 2. The first and second hook- shaped reinforcing bars 20, 30 are staggered in height as shown in fig. 1, so that the first hook-shaped reinforcing bar 20 and the second hook-shaped reinforcing bar 30 are prevented from being directly collided and cannot be assembled in place during assembly. Vertical reinforcing bars 21, 31 extending in the height direction of the wall block are welded to the first and second hook- shaped reinforcing bars 20, 30 near the hook bends, i.e., near the roots of the hooks, respectively. One side of the wall block 10 is provided with a groove along the vertical direction, the first or second hook-shaped reinforcing steel bar 30 is positioned in the groove, and the groove wall at the upper end of the groove is provided with a gap 60. The first and second hook- shaped reinforcing bars 20, 30 of the adjacent wall blocks can form a mutual buckling in the groove, and the mutual buckling is carried out by the vertical reinforcing bars 21, 31.
During assembly, because the first hook-shaped reinforcing steel bar 20 and the second hook-shaped reinforcing steel bar 30 on the adjacent wall blocks 10 are staggered in height and opposite in hook shape, and vertical reinforcing steel bars 21 and 31 exist, when the wall block on the left side moves rightwards as shown in fig. 2, the outer ends of the two hook-shaped reinforcing steel bars 20 and 30 are blocked by the vertical reinforcing steel bars 31 and 21 respectively to be elastically bent, the outer ends of the right hook-shaped reinforcing steel bars 20 and 30 pass through the vertical reinforcing steel bars 31 and 21 to restore the shape, and at this time, when the wall block 10 on the left side is required to be withdrawn leftwards, the vertical reinforcing steel bars 21 and 31 can block the hook-shaped reinforcing steel bars 30 and 20. That is, the first and second hook- shaped reinforcing bars 20 and 30 are engaged with each other in the form of a letter "within the groove, and the engagement is not released without breaking the hook shape of the hook-shaped reinforcing bars 20 and 30. The hook angles of the first and second hook- shaped reinforcing bars 20 and 30 are between 30 ° and 60 °, which is most advantageous for exerting the maximum hook-shaped fastening force.
In practice, the hook-shaped bending angles and the extension lengths of the hook-shaped reinforcing bars of different thicknesses need to be adjusted adaptively to ensure the length adaptation of the first hook-shaped reinforcing bar 20 and the second hook-shaped reinforcing bar 30. The length adaptation is also for example: the hook shape of the two hook-shaped reinforcing steel bars 20 and 30 is symmetrical, and the sum of the extension lengths in the width direction of the wall block is larger than the depth of the groove plus the thickness of at least 2 left and right reinforcing steel bars, so that the requirement can be met.
After the reinforcing steel bar is assembled in place, concrete is poured or heat-insulating filler is filled in the groove through the notch 60 on the groove, so that the connection reliability between the wall blocks 10 can be further enhanced, high temperature, noise and the like can be effectively isolated, and the building comfort is improved. It is preferable that the end surface of the groove and the upper portion of the groove wall be provided with an asbestos pad 50, which prevents damage to the groove wall of the groove during assembly and transportation of the block. The asbestos pad 50 is laid in the die to be prefabricated and machined integrally when the wall block 10 is prefabricated, and machining is more convenient. Specifically, in the process of erecting the mold, the asbestos pads 50 are arranged on the top surfaces of the groove walls of the grooves and the inner upper parts of the side walls, and then concrete is poured to obtain the concrete.
Preferably, wall piece 10 up end and terminal surface limit evenly are provided with perpendicular to the outside auricle 11 of connecting of face respectively down, auricle 11 and the welding of steel reinforcement fossil fragments 40, and auricle 11 and wall piece 10 edge joint portion outside have to the outstanding bending 12 of wall piece face, and auricle board outer end has connecting hole 13. The primary connection of the wall blocks can be realized through the connecting lug plates 11, and particularly, the position of the wall blocks is fixed before concrete or filler is poured in the grooves, so that the wall blocks are prevented from moving in the pouring process. The arrangement of the bend 12 plays a role in strengthening the structure of the connection lug 11, and meanwhile, the lateral force of the wall block 10 during assembly and use can be buffered and deformed by the bend to be absorbed, so that stress concentration on the joint of a screw, a bolt or concrete and the connection lug 11 is avoided.
The processing method comprises the following steps: when the steel bar keel 40 is processed, connecting lugs 11 are respectively arranged at the bottom and the top of the wall block 10 and are respectively welded with the steel bar keel 40; the outer side of the joint part of the connecting lug plate 11 and the edge of the wall block 10 is pre-processed with a bend 12 protruding towards the surface of the wall block, and the outer side of the connecting lug plate is pre-processed with a connecting hole 13. When the building is assembled, the adjacent wall blocks 10 are abutted and aligned, and then the wall blocks are preliminarily fixed by the connecting lug pieces 11 and the expansion bolts.
