The petals of an adjacent group are oppositely oriented relative to the group.

Preferably, the pattern protrusions or the pattern grooves are formed by arranging a plurality of petals in the same or different directions.

The arrangement refers to the petal individual arrangement in any direction.

Preferably, the petals extend obliquely from the combining surface to the tail end of the pattern bulge or the pattern groove. The side surfaces of the petals are inclined surfaces, so that a rough surface can be better established, and the national standard requirements are met.

Preferably, the depth of the pattern protrusions or pattern grooves is greater than 5 mm.

Preferably, a plurality of horizontal muscle and vertical muscle equidistance arrange the setting.

Preferably, the lengths of the transverse ribs at the two outer ends of the prefabricated wall panel in extension are equal, and the lengths of the longitudinal ribs at the two outer ends of the prefabricated wall panel in extension are equal.

Preferably, the area of the patterned projection or groove on a single bonding surface is greater than or equal to 80% of the area of the bonding surface.

The above design parameters can meet the requirements of specifications JGJ 1-2014.

Compared with the prior art, the beneficial effects of the utility model are that:

firstly, reinforcing steel bars are arranged on a joint surface of the prefabricated wall panel and extend to the outer side, and under the condition that the post-cast concrete molding is met, a rough surface is arranged on the joint surface to meet the standard requirement;

secondly, the rough surface of the prefabricated wallboard can be formed by a forming tool in one step, secondary processing is not needed to be carried out on the rough surface, the process cost and the personnel cost are saved, the labor intensity is reduced, and the productivity and the efficiency are improved.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1 to 4, in the prefabricated wall panel 1 provided in this embodiment, pattern protrusions or pattern grooves 12 are provided on a joint surface 11 between the prefabricated wall panel 1 and the post-cast concrete laminated layer.

In this embodiment, the pattern protrusions or pattern grooves 13 are formed by three sets of petals regularly arranged, the petals of the first set and the third set face to the left, and the petals of the middle set face to the right.

In other embodiments, the petals in each set may be oriented differently, or each petal may be oriented differently.

The petals extend obliquely from the bonding surface to the end of the pattern projection or pattern groove 12.

The petals can be in an olive shape with an axisymmetric structure, the external dimension of the petals is related to the dimension of the joint surface, and the petals are uniformly distributed on the joint surface 11 to design the proper external dimension of the petals.

The depth of the pattern protrusions or pattern grooves 12 is greater than 5 mm. The area of the patterned projections or grooves 12 on the single bonding surface 11 is greater than or equal to 80% of the area of the bonding surface.

Prefabricated wallboard 1 still includes many horizontal muscle 13 and vertical muscle 14, horizontal muscle 13 sets up with vertical muscle 14 crisscross and runs through faying face 11 extends to the outside of prefabricated wallboard 1.
