The method comprises the steps that a vertical joint between prefabricated concrete wallboards needs to be connected, the common practice in the current engineering is equivalent to cast-in-place secondary pouring connection, overlap reinforcing steel bars are reserved on the side surfaces of the prefabricated concrete wallboards from bottom to top, commonly called 'Huzi ribs', the vertical reinforcing steel bars and the overlap stirrups are configured and bound in overlap sections of the 'Huzi ribs' on site, then concrete is poured by a formwork, and the connection mode is adopted by JGJ 1-2014 'technical regulations of assembled concrete structures and GB/T51231-2016' technical standards of assembled concrete constructions.
When the wallboard component is prefabricated in an equivalent cast-in-situ secondary pouring connection mode, in order to reserve the 'Hu-shaped ribs', the side mould is perforated or reserved according to design requirements so as to enable the 'Hu-shaped ribs' to penetrate out of the side mould. The design and the processing are troublesome, the labor and the material are wasted, and the die stripping is also laborious; the die has very low universal rate, basically is a set of dies for one project, and causes serious waste; the 'Huzi tendon' is not suitable for industrial flow line production, so that the production efficiency is low. When the method is installed on site, the method is equivalent to cast-in-place secondary pouring connection, one cast-in-place working procedure is added, the construction period is prolonged, and the advantages of the assembly type construction period are not highlighted. Finally, the assembled building has high cost, and is not beneficial to the popularization of building industrialization.
Because the design is not careful or the management and control is not tight when the wallboard is prefabricated, the reserved position and the reserved dimension of the 'Hu Zijin' can be wrong or have large errors, the installation is mutually collided, the site is difficult to correct in place, the wallboard is hard to smash, and even the reinforcing steel bars are cut off, so that the potential safety hazard of the structure is caused.
For a multilayer assembled concrete shear wall structure, the stress is much smaller than that of a high-rise structure, and the connection between wallboards can be realized by adopting a relatively simple connection mode.
The structure of the bolt connection precast concrete wallboard represented by German hafene, the bolt passes through the pre-buried connecting piece arranged on the precast concrete wallboard at one side, and then the bolt passes through the pre-buried internal thread sleeve on the precast concrete wallboard at the other side, so the structure of the bolt connection can only bear tensile force and shearing force and cannot bear pressure.
How to design a simple structure, convenient to use, can connect precast concrete wallboard, and can bear the connection structure of pulling force, shearing force and pressure is the problem that the skilled person need to solve.

In the bolt connecting assembly of the present invention, the pressure screw 310 of the pressure bolt 300 is installed in the first internal threaded hole 120 of the first connecting member 100, after the first precast concrete wall panel 10 and the second precast concrete wall panel 20 are hoisted to the preset positions and fixed, the pressure bolt 300 is rotated so that the pressure nut 320 of the pressure bolt 300 abuts against the second connecting surface 220, the serial screw 410 sequentially penetrates the supporting through hole 230 and the serial threaded hole 330, and the second connecting member 200 is connected with the pressure bolt 300; by rotating the pressure bolt 300, the pressure bolt 300 can be moved out of the first internal threaded hole 120 and extend into the first internal threaded hole 120, so that the gap error between the first precast concrete wall board 10 and the second precast concrete wall board 20 is suitable, and the pressure nut 320 of the pressure bolt 300 can bear against the second connecting surface 220, so that the first precast concrete wall board 10 and the second precast concrete wall board 20 are connected through the bolt connecting assembly, and the connected first precast concrete wall board 10 and second precast concrete wall board 20 can bear the tensile force, the compressive force and the shearing force, and therefore, the bolt connecting assembly is a connecting device with composite bearing capacity.
In this embodiment, the first connector 100 is prefabricated in the first prefabricated concrete wall panel 10 by installing the first connector 100 in a prefabricated module, and pouring concrete into the prefabricated module to form the first prefabricated concrete wall panel 10; the second connector 200 is prefabricated in the second prefabricated concrete wall panel 20 in such a manner that the second connector 200 is installed in a prefabricated module into which concrete is poured to form the second prefabricated concrete wall panel 20. The prefabrication module is determined according to actual construction requirements.
The first precast concrete wall panel 10 is precast on a side surface for inserting the pressure bolt 300 to form a first groove 11, and the first connection member 100 is penetrated from a bottom surface of the first groove 11.
Because the pressure screw 310 is screwed into the first internal threaded hole 120 before the first precast concrete wall panel 10 is lifted to the preset position, and the first groove 11 is provided, the pressure bolt 300 can be inserted into the first groove 11 before the first precast concrete wall panel 10 is lifted to the preset position, that is, the pressure nut 320 of the pressure bolt 300 does not protrude from the first panel body mounting surface, so that the first precast concrete wall panel 10 can be ensured not to collide with other structures due to the protruding pressure nut 320 in the process of lifting the first precast concrete wall panel 10 to the preset position.
The first connecting member 100 is a sleeve, and the first internal threaded hole 120 is disposed on an inner wall of the sleeve. The inner wall of the sleeve is conveniently inserted with the pressure screw 310 of the pressure bolt 300.
The second precast concrete wall panel 20 is precast on a side surface for inserting the tandem bolt 400 to form a second groove 21, and the second connection member 200 is penetrated out of the bottom surface of the second groove 21. When the first precast concrete deck 10 is coupled with the second precast concrete deck 20, the pressure nut 320 can be inserted into the second recess 21 so that the pressure nut 320 is closely contacted with the second coupling face 220 of the second coupling member 200.
Because the first connecting piece 100 and the second connecting piece 200 are both independent module structures and have strong universality, the connecting piece can be suitable for the working conditions of connecting the first precast concrete wallboard 10 and the second precast concrete wallboard 20 with different structures.

The hollow interior 210 and the bolt mounting hand hole 22 are then plugged to complete the installation of the bolted assembly.
The first precast concrete wallboard 10 is precast with a first groove 11 on a side surface for inserting the pressure bolt 300, and the first connecting piece 100 penetrates through the bottom surface of the first groove 11; when the first precast concrete deck 10 is not hoisted to a preset position, the pressure nut 320 of the pressure bolt 300 is inserted into the first groove 11.
