Light partition board is usually installed in a building, non-load-bearing parts do filler wall < strong >, < / strong > installation site of short pier shear structure, are the large span and large bays, the largest settlement deformation, load carrying capacity the weakest point, cracking ratio is large; any object in the atmosphere are change, due to wallboard single block independence, joint rabbet is connected and assembled specificity, when the structure is subjected to concentrated load and vibration, stress and external changes, is very easy to cause the plate and plate junction of longitudinal cracks appear in issue.
At present the domestic light partition board, two plate joint rabbet are concave and convex groove and a V edge shape groove structure, wallboard installation after longitudinal crack problem, its reason is because the concave-convex groove and V edge groove, wall panels and mortar for joints of two materials of different dry and wet, water absorption rate and contraction differences in performance, mutual adhesion is poor, can not be two boards firmly bonding, the wallboard single block independence, the cracking was caused by the basic reason. When the housing structure stress changes, because the stress magnitude and direction of each are not identical, each plate there are separate contraction or expansion of the change with the seasons change, temperature, humidity and transmigration of lifting, wall cracks caused by multiple natural, rework, manpower, material and financial resources, time of Fei Lang.
Brick wall slight change why not cracking, because the brick wall around the lap force, the small stress evenly dispersed offset each other, so that the whole metope become one.
The concave-convex groove and V edge groove, wall mounted upon the causes of longitudinal cracks on brick walls, overlapping principle, Jingzhou tianming of new materials research institute, ceaseless exploration painstaking research dovetail interlock to prevent cracks structure, wall mounted, mortar will two dovetail type hollow slot number of butt compaction, dry hard mortar every 60 cm, the wallboard has a dovetail type solid core connection column, so that the two wallboard docking interlocking, the two plate is tightly buckled with each other, such as brick was connected to form block wall, when the housing structure stress changes, local variation of dispersion to the whole wall, together with material through scientific ratio, so that the existing 36% hollow ratio of lightweight partition board in the production process, the uniform expansion of the wall again, formed inside the bread honeycomb, increased wall toughness, completely solve the problem of light wallboard longitudinal cracks. Dovetail interlocking, unique structure, domestic initiative, access to national patents, to fill China's light wall panel in interlocking connection blank, will be our country " wall material innovation and promotion of energy-saving construction" to create a new road.
In the GRC lightweight partition board crack prevention seminar, the experts agreed that the GRC swallowtail interlocking anti cracking of lightweight partition board, interlocked and connected into a whole, become the whole wall is to prevent the partition plate cracks of effective measures, by experts praise, fill our country wallboard seam interlocking blank.
Jingzhou light partition board machinery factory, in order to make the patent technology to service the community, make more colleagues to benefit, avoid detours to reduce losses, by my patented technology developed by dovetail interlocking anti cracking of lightweight partition board production equipment, dovetail interlocking anti crack automatic light partition wall board extruding machine and other ancillary equipment。 |
