The optional size given by the wire slot hole 81 and the heat insulation hole 91 has a design advantage that when the upper and lower planes are coated with the viscose 12 for mutual bonding and fixing of the building blocks, the viscose 12 coated on the upper and lower planes in a plane shape can not sink into the wire slot hole 81 and the heat insulation hole 91 by combining the viscosity of the conventional viscose, so that the bonding and fixing effects of the bonding surface can be effectively ensured, and the process steps of filling slurry with the depth of not less than 15mm into the two ends of each through hole to form a flat bonding surface before coating the viscose, which are involved in the Chinese patent application CN111663710A, can simplify the subsequent construction process and ensure the bonding effect at the same time.
In the implementation, the minimum thickness from the line slot hole 81 to the vertical side face 5 at the corresponding side can be 12-20 mm; the distance between the wire slot holes 81 of the group of wire slot hole units 8 can be selected to be 7-8 mm, the distance between the heat insulation holes 91 of the group of heat insulation hole units 9 can be selected to be 7-8 mm, and the distances between the wire slot hole units 8 and the heat insulation hole units 9 and between the wire slot hole units 9 can be selected to be 8mm; the protruding height of the tenon and the concave depth of the mortise can be selected to be 7-10 mm (the protruding height of the tenon is preferably less than the depth of the tenon by 1mm, and the width of the tenon is preferably less than the width of the tenon by 2-8 mm); the width of the mortise can be selected to occupy 55-66% of the thickness of the masonry; the depth of the first racking grooves 63 can be selected to be 8-9 mm and the width thereof can be 8mm, and the depth of the second racking grooves 72 can be selected to be 10-11 mm and the width thereof can be 5mm; the third racking grooves 74 can be optionally recessed to be flush with the corresponding mounting end surfaces 4 and have proper width. The adjacent inner side walls of the two first racking grooves 63 can also have a certain inclination and are matched to form a structure which is gradually reduced towards the free end, so that the U-shaped connecting piece can be conveniently accommodated if necessary.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
