Step S4, by carrying out seat slurry on the inside of prefabricated outer wall panel, last connection joint seal operation is completed.
Further, the variant part that step S3 completes that the discriminant approach of accurate joint seal connection is construction tool stops deformation；
Further, it is concrete grout that step S4, which sits slurry,.
Compared with prior art, technical effect of the invention are as follows:
Construction tool of the invention is formed irregular easily-deformable joint seal tool, is had and used by the bending of different angle
The drip-preventing function of concrete grout leakage is controlled when slip casting joint seal and accelerates molding molding function, Yi Jiyong for controlling joint seal
In the function that control prefabricated outer wall panel sleeve grouting mouth is not blocked by concrete grout, which acts on assembly concrete
It builds at conversion layer, is located on cast-in-place structural bearing wall, fallen by the lifting of top prefabricated outer wall panel so that joint seal tool produces
Change shape, forms firm joint seal shape, effectively avoid sit starch during outside spillage, reduce joint seal sit slurry be slurry wave
Take, be effectively ensured reinforced bar sleeve grouting quality of connection and assembled architecture using safe, improve the whole strong of joint seal
Degree, it is ensured that the construction quality of joint seal, construction tool of the present invention, simple structure and reasonable design and processing and fabricating are easy, input cost
Lower, of the invention construction method, practical operation is easy, economical and practical, good application effect.

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawings and examples
Invention is further described in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to FIG. 1 to FIG. 4；
A kind of construction tool for assembled architecture conversion layer joint seal provided by the invention, generally steel form gasket,
Including the fixed part 7 with fixation hole 8 and the variant part 9 being folded upward on one side positioned at fixed part 7, the fixed part 7 is horizontal
Be fixed on cast-in-place structural bearing wall 3, the variant part 9 in the horizontal direction upwards in turn bend 45 degree, 135 degree, finally it is curved
It is parallel with fixed part 7 to roll over 180 degree.
The specific practice of construction tool 1 are as follows:
1) by steel form gasket according to the position of embedded bar 4 on cast-in-place structural bearing wall 3 and spacing fixed part into
Row punching, forms fixation hole 8；
2) steel form gasket another side is subjected to 45 degree, 135 degree, 180 degree bending upwards, forms the deformation of construction tool 1
Portion 9.
Wherein, the length of 45 degree of bendings, 135 degree of bendings, the 180 degree bending of variant part 9 is sequentially reduced, specifically can be according to reality
Border wall thickness and 3 embedded bar of cast-in-place structural bearing wall, 4 number of rows spacing determine.The upper surface of the 180 degree bending place of variant part 9 is logical
Double-sided adhesive is crossed to be connected with prefabricated outer wall panel 2.
The present invention also provides a kind of construction methods for assembled architecture conversion layer joint seal, comprising the following steps:
Step S1, the applied cement mortar 5 on cast-in-place structural bearing wall 3；
Step S2, it by above-mentioned construction tool 1, is placed on the embedded bar 4 of cast-in-place structural bearing wall 3, pre-buried steel
Muscle 4 passes through fixation hole 8, completes the initial connection of joint seal, 7 level of fixed part is fixed on cast-in-place structural bearing wall 3, so that applying
Work tool 1 more fits on cast-in-place structural bearing wall 3；
Step S3, hoisting prefabricated Side fascia 2, is placed in the top of construction tool 1, and prefabricated outer wall panel 2 is fallen, so that construction
The variant part 9 of tool 1 generates deformation, completes accurate joint seal connection, and the discriminant approach for completing accurate joint seal connection is construction tool 1
Variant part 9 stop deformation so that gap plugging is more closely knit, prevent from sitting slurry joint seal spillage, accelerate the molding for sitting slurry, it is prefabricated
Side fascia 2 is accurately connected and fixed, and indicates that prefabricated outer wall panel 2 and the connection of cast-in-place structural bearing wall 3 have been completed, and is formed secured
Joint seal shape, can carry out sit slurry joint seal；
Step S4, by carrying out seat slurry on the inside of prefabricated outer wall panel, last connection joint seal operation is completed, it is mixed for sitting slurry
Solidifying soil paste 6.
The spillage phenomenon of concrete grout 6 during construction tool 1 effectively prevent seat to starch improves prefabricated outer wall panel 2 and shows
It pours the Connection Time of structure bearing wall 3, while construction tool 1 effectively accelerates the molding time of concrete slurry 6, first carries out pre-
Side fascia 2 processed lifts, then carries out sitting slurry closure, prevents from sitting the injected hole that slurry blocks reinforced bar sleeve during sitting slurry, reinforcement
Joint seal intensity, improves construction quality.
Obviously, above embodiment is just for the sake of clearly illustrating example, on the basis of the above description also
The variation or variation of other forms can be made.Therefore, thus changes and variations that derived from still fall within this
Within the protection scope of invention.
