Compared with a solid partition board without round holes, the partition board with the structure not only reduces the weight of the wall body, but also enhances the sound insulation effect. Under the condition that the strength design requirement is met, the diameter of the round holes 2 is as large as possible, the distance between the round holes 2 is as small as possible, so that the weight of the partition plate is reduced, the cost is reduced, and the round hole partition plate of the type is generally unsuitable for on-site slotting.

As shown in fig. 2 to 5, the prefabricated light-weight round hole partition plate is different from the round hole partition plate shown in fig. 1 in that at least one side of the plate body 1 is provided with a plurality of slotting marks 3, the slotting marks 3 are positioned at the position where the perpendicular bisector b of the central connecting line of adjacent round holes perpendicularly intersects with the outer surface of the plate body 1, and the shape of the slotting marks 3 is not limited; the slotting mark 3 is a position mark of a field slotting, when the field slotting is performed, a pipeline slot 4 for embedding a pipeline 5 is formed in the slotting mark 3 on the plate body 1 according to the diameter d of a pipeline of equipment, the opening of the pipeline slot 4 is outwards, the pipeline slot 4 is of a symmetrical square slot structure, and the width of the pipeline slot 4 is matched with the diameter d of the pipeline 5. In the first embodiment shown in fig. 2 to 4, the slotting marks 3 are arranged on two sides of the plate body 1, the pipeline slots 4 arranged on two sides can be arranged in a staggered manner, or can be arranged oppositely, and a space is reserved between the bottoms 41 of the pipeline slots 4 arranged oppositely; in a second embodiment shown in fig. 5, a slotting index 3 is provided on one side of the plate body 1.
In order to prevent the performance of the prefabricated light round hole partition plate from being reduced due to the fact that the size of the on-site opened pipeline groove 4 exceeds the designed allowable slotting area, slotting area lines 6 are arranged on the outer surface of the plate body 1, the slotting area lines 6 are matched with the maximum diameter (i.e. d) size of the pipeline of the embedded equipment of the round hole partition plate with the specification, the slotting area lines 6 are symmetrically arranged on two sides of a slotting sign 3 and used for indicating slotting areas c on the plate body 1, and slotting is carried out in the slotting areas c indicated by the slotting area lines 6 during on-site slotting; the actual grooving width must not be greater than the width of the grooving area line 6, and the grooving mark 3 should coincide with the center line of the pipeline groove 4 opened in the field.

the central connecting line length (the distance between two slotting marks 3) Z=2X+d+D=2 gamma is 30mm+20mm+60=140 mm for two adjacent round holes 2;
the distance between the grooved region line 6 and the center of the adjacent circular hole 2 may be equal to x+d/2=20mm+60 mm/2=50mm.
The performance of the prefabricated light round hole partition boards with two specifications is detected by adopting an actual measurement and engineering calculation mode, wherein when the prefabricated light round hole partition boards are subjected to engineering calculation, the whole wall body provided with the round hole partition boards can be equivalent to a cross steel support frame, the calculation is carried out according to a support system, the calculation can also be carried out according to a frame wall body by directly adopting a finite element two-dimensional modeling mode, for example, under the condition that the force and the lateral movement are equal in an elastic stage, the tensile rigidity of the cross steel support is sought, and the support is needed to act in the push-pull direction and the push-pull direction in a low cycle reciprocating loading mode, so that the mode of the cross support is adopted to meet the actual condition (the specific calculation method refers to the national standard design atlas of 08CJ13 steel structure mosaic energy-saving building construction, and the quality standard and the performance detection method refer to the ASA industry standard JG/T169-2016 for the light strip board for building partition walls).
The results of the performance test (after slotting) of the specific prefabricated light round hole partition plate are shown in table 1.
