On the basis of above-described embodiment, in another embodiment of the present invention, described water-proof strip can be made for elastomeric material, a part for described water-proof strip is embedded in precast wall body, another part is protruding to the horizontal split seam of contiguous prefabricated body of wall split or vertically stitches in split, and the projection of adjacent described water-proof strip extrudes mutually.Like this, when water-proof strip is that elastomeric material is made, a part for described water-proof strip is embedded in precast wall body, another part is protruding to the horizontal split seam of contiguous prefabricated body of wall split or vertically stitches in split, when the projection of adjacent described water-proof strip extrudes mutually, by the stretch-draw of unbonded prestressing tendon 30, make the moment between prefabricated panel 20 assembled up and down be applied with compressive stress, thus the waterproof, seepage control ability of horizontal joint is greatly improved; And after in vertical split seam, water-proof strip is set, as correspondingly arranged horizontal strain component as the locking member of activity or the posttension unbonded prestressing tendon 30 that is horizontally placed in prefabricated panel 20, make the moment between laterally assembled side by side prefabricated panel 20 be applied with compressive stress, thus the waterproof, seepage control ability that vertical split is stitched is greatly improved.

On the basis of above-described embodiment, in another embodiment of the present invention, described water-proof strip can be made for elastomeric material, and described water-proof strip independently can be arranged in described horizontal split seam or vertical split seam and to be extruded compression by the prefabricated panel 20 of adjacent both sides.Like this, when water-proof strip is that elastomeric material is made, when described water-proof strip to be independently arranged in described horizontal split seam or vertical split seam and to be extruded compression by the prefabricated panel 20 of adjacent both sides, independently water-proof strip can be applied by convenient construction, simultaneously, by the stretch-draw of unbonded prestressing tendon 30, make the moment between prefabricated panel 20 assembled up and down be applied with compressive stress, thus the waterproof, seepage control ability of horizontal joint is greatly improved; And after in vertical split seam, water-proof strip is set, as correspondingly arranged horizontal strain component as the locking member of activity or the posttension unbonded prestressing tendon 30 that is horizontally placed in prefabricated panel 20, make the moment between laterally assembled side by side prefabricated panel 20 be applied with compressive stress, thus the waterproof, seepage control ability that vertical split is stitched is greatly improved.

The present invention propose a kind of with Vertical dimension, level to power consumption connector and the assembly concrete wallboard structural system of posttension prestressing without bondn, this system site assembly simple and quick and under transverse load effect lateral deformation very large, have good self-recoverage center capacity, this structural system can meet the antidetonation demand based on performance.Posttension prestressing without bondn assembly concrete wallboard structural system is combined vertical, level improves anti-seismic performance from assembled wallboard structure to power consumption connector by the present invention, make structure produce very large lateral displacement and permanent set when large shake or damage very little, there is the ability at self-recoverage center.Therefore this prestressing force assembly concrete wallboard structural system has important practical value and meaning in the assembling construction and antidetonation of industrialization of construction industry.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
