Description
Technical Field

The light partition board is used as non-bearing inner partition in common industrial building, residential building and public building engineering. The light partition slat has the advantages of moisture resistance, shock resistance, sound insulation, fire resistance, heat preservation, small occupied area, good strength, convenient construction and the like. The splicing structure of the partition wall batten in the prior art generally adopts concave-convex butt joint, and is connected by plastering during splicing, one of the reasons of cracking and cracking phenomena is that slurry filled in a splicing gap is too thin, the bonding force and resistance of a secondary connector formed after the slurry is solidified are very low, and when a batten wall body deforms due to stress, humidity, temperature field changes and the like, the secondary connector can be partially separated from a contact surface, so that cracks appear at a joint; therefore, the problem that the split joint part cracks still exists after the partition wall batten adopting the male and female groove structure is spliced.
The second reason for the cracking phenomenon is that the fit clearance of the partition wall batten with the male and female groove structure is not uniform during assembly; the unilateral almost laminates in some cases, and the thick liquids are connected to the unable closely knit packing, and even if the wall body of such assembling does not crack, sound insulation effect is also very poor.
After splicing and caulking are completed, a layer of grid cloth and anti-crack mortar are required to be coated on a large-area whole wall surface to balance the stress of the wall body and reduce cracking at weak joints. The secondary construction of grid cloth and anti-crack mortar are adopted for plastering, so that the defects of long construction period, high construction cost, high labor intensity and the like are overcome. This approach also does not meet the assembly requirement; moreover, the method cannot thoroughly solve the problem that the splicing position of the partition wall batten does not crack, as is well known, after the partition wall in the batten cracks, the effect of filling the cracks by adopting a repairing mode is poor, and the cracks still occur in the later period because the slurry repaired at the cracks cannot form a firm secondary connecting body.
Therefore, the utility model provides the light inner partition wall, the partition wall batten thoroughly solves the problem that the partition wall batten cracks at the abutted seam, and the construction efficiency is high.
