Technical Field
The utility model relates to a architectural decoration engineering technical field, more specifically relate to a wide component for building subsiding crack of application scope.
Background
The settlement joint is a vertical joint provided to prevent the house from being damaged due to the uneven settlement of the foundation of each part of the building. Basic overview of the settlement joint: when the height, load and structural form of adjacent parts of the house are very different and the foundation is weak, the house may be unevenly settled, so that some weak parts are cracked. For this reason, settlement joints should be provided at appropriate positions such as complicated plane or body turns, height changes, loads, compressibility of the foundation, and methods of foundation treatment, which are significantly different. The settlement joint divides the building into a plurality of independent units capable of freely settling, the obvious difference between the settlement joint and the expansion joint is that the settlement joint is completely penetrated from the building foundation to the roof, the structure of the settlement joint related to the foundation property and the building height is basically the same as the expansion joint, but the construction method of the cover joint must ensure that two adjacent independent units can freely settle. In a brick-concrete structure, two schemes are generally adopted for the foundation of buildings on two sides of a settlement joint: (1) the cantilever beam foundation is normally arranged on the foundation of one side wall of the settlement joint, the longitudinal wall on the other side is born by the cantilever beam in an overhanging way, and the beam end is additionally provided with a foundation beam and a light partition wall; (2) the double-wall scheme is adopted, namely, bearing walls are arranged on two sides of the settlement joint so as to ensure that each independent unit is hermetically connected with longitudinal and transverse walls, and the structural integrity is good. When the distance between the two bearing walls is small, in order to overcome the eccentric stress of the foundation, two rows of staggered independent foundations on the plane arrangement can be adopted, and the foundation beams of the bearing walls are placed on the foundations.
In building wall decoration engineering, the subsiding crack needs to be reserved at the architectural surface, for guaranteeing pleasing to the eye, subsiding crack department generally sets up the lid seam component, and the lid seam component that current subsiding crack set up in this department includes the panel, anchor clamps and spring, the spring that sets up two horizontal arrangements is connected through the mount, spring other end connection anchor clamps, connection panel between two anchor clamps, thereby cover the subsiding crack through the panel, but anchor clamps simple structure, only go the panel card through the draw-in groove can, only be suitable for the panel of a thickness, in actual work progress, the panel of different thickness probably is used, still need produce the anchor clamps that correspond the draw-in groove width, not only application scope is little, and the centre gripping is not firm.
