Description

M-shaped keel leveling structure

Technical Field

The utility model relates to a fossil fragments especially relate to a M type fossil fragments leveling structure.

Background

The construction process of traditional wall surface leveling and the limitation of veneer compatibility can not satisfy the decoration requirements of high-efficient construction, diversified selection, dry construction, environmental protection, fire prevention and environmental protection. Along with the development of the interior decoration industry, the assembly type decoration process obtains remarkable performance, the wall surface leveling construction process is improved on the basis of the traditional process, and although the existing assembly type decoration wall surface leveling construction process realizes dry construction, a plurality of problems still exist, such as small leveling degree adjusting range, low leveling precision, complex leveling and difficult operation, and complicated construction procedures. The keel has compact surface, poor adhesion and asymmetry, has high requirements on the operation manual of workers, and is difficult to maintain and repair at the later stage. The application scene is single, and the problems that the existing various walls such as hollow block walls, concrete walls, block brick walls and the like cannot be used generally are solved, so that the technology needs to be updated and replaced.

The existing wall surface installation generally comprises the following links: (1) after the wall surface is punched, a straight plastic expansion pipe or a wood wedge is fixed in the wall; (2) screws or other threaded products such as expansion screws are screwed into the straight plastic expansion pipes or the wood wedges to be combined with the wall body, and horizontal in-and-out adjustment is carried out according to the distance of the screws protruding out of the wall surface; (3) installing the W-shaped wall keel at a screw or other threaded products, and fastening by using a screw or a nut; (4) leveling installation is accomplished by adjusting or rotating screws or other threaded product slots.

The above process has the following disadvantages: firstly, after the straight plastic expansion pipe or the wood wedge is fixed and needs to be punched on the wall surface, the straight plastic expansion pipe or the wood wedge is driven into a wall hole by a hammer, the application range of the straight plastic expansion pipe or the wood wedge has certain limitation, when the wall body is a hollow brick base layer, the straight expansion pipe or the wood wedge has insufficient tension due to the fact that the wall body is hollow, and cannot be tightly combined with the surrounding wall surface in an expansion mode, so that the fastening force is poor; the problems of insecure connection, easy falling, easy inclination and the like exist, and the installation of the keel is insecure or uneven. Meanwhile, in the construction process, the keel flatness adjustment and later maintenance are difficult to carry out by using the common straight expansion pipe fire wood wedge, and the hole and the expansion pipe cannot be reused, so that the hole which is used for multiple times can be expanded when the expansion pipe is expanded for one time, and the same eyelet is used for multiple times, so that the expansion pipe is easy to slide, the expansion pipe is easy to break and deform, and the phenomena of screw deviation and the like are easy to cause; the original screw screwed into the expansion pipe has the problems of thin screw rod and shallow notch, and the notch is easy to slide in the actual construction process, so that the function of screwing the screw cannot be realized, and the function of leveling the keel cannot be realized. Meanwhile, in the prior art, the screw is of a polygonal structure, the production process is complex, and the cost is high. In addition, the W-shaped keel in the existing W-shaped keel is of an asymmetric structure, and the upper end face and the lower end face of the keel are 2 in shape, so that the production process is complex, the upper end face and the lower end face of the keel need to be distinguished in the installation process, and the installation difficulty of workers is increased. The existing W-shaped keel is in contact with a veneer, a V-shaped groove with the depth of 3-8 mm is arranged at the front of the existing W-shaped keel, so that the contact surface of the keel and the veneer is small, the glue is not firmly bonded, and the W-shaped keel cannot be tightly attached to a base plate due to the fact that the material bonding surface is uneven when the existing W-shaped keel is used.
