Description

Technical Field

[0001] The present invention relates to the technical field of building wall decoration, and particularly relates to a prefabricated overhead base layer and an installation method thereof. Background Art

[0002] Wall overhead is generally divided into three types. First, the plaster bump veneer overhead system uses mortar or gypsum-based adhesives that are plastic before initial setting. When installing the panel, the mortar or gypsum-based adhesive is extruded, thereby correcting the flatness error of the wall. Second, the light steel keel overhead system uses light steel keels as the support framework, connects to the main body through fixed fasteners, and the panel is fixed to the light steel keel by sticking or nailing to achieve wall overhead. Third, the resin bolt overhead system corrects the flatness error of the structural wall through the screw thread engagement of the resin bolts, and adjusts the overhead space by adjusting the bolts.

[0003] Each of the above three methods has its own advantages. However, the plaster bump veneer overhead system has a large amount of work, requires wet processing, is easy to dirty the ground, and requires secondary application of mortar. For the light steel keel overhead system, the panel is fixed by sticking and nailing, and it is generally difficult to remove the panel, so the later repair is difficult. For the resin bolt overhead system, the overall strength is low, so it still cannot meet people's usage needs. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a prefabricated overhead base layer and an installation method thereof with reasonable structural design, fast and efficient installation.

[0005] The technical solution of the present invention is as follows:

[0006] A prefabricated overhead base layer includes an original wall surface, a frame base layer, a base component and a convex component. A plurality of rows of leveling components are arranged on the original wall surface. Each row of leveling components includes several base components arranged at intervals, and the base components of adjacent two rows of leveling components are corresponding in position. The convex component is fixedly arranged on the frame base layer, and the convex component corresponds to the base component one by one. The base component and the convex component are fixedly connected, and the adjustment and fixation of the frame base layer can be realized through the base component.

[0007] Further, the frame base layer includes a group of unit frames, and each unit frame includes a ceiling keel, a floor keel, a side keel, a vertical keel and a cross brace keel.

[0008] Further, the base component includes a base member, a square rod member and a fastener. The square rod member is in plug-in sliding fit with the base member and is fixed by the fastener.

[0009] Further, at least two base components in each row of leveling components are grouped together and fixed to the original wall surface through a lining board.

[0010] Further, the base member is T-shaped and includes a square block and a square tube provided on the square block. A socket is provided in the middle of the square tube.

[0011] Further, the square rod member is mouth-shaped, with both ends penetrated, and waist-shaped round holes are respectively provided on both side surfaces.

[0012] Further, the convex member is shaped like a capital "J" and is wrapped around the outside of the square rod member.

[0013] Further, the convex member is installed on the vertical keel and the side keel of the unit frame.

[0014] Further, the base assembly and the lining board are jointly fixed to the original wall surface by expansion screws.

[0015] An installation method for an assembled overhead base layer includes the following steps:

[0016] 1) First, perform line marking and positioning on the original wall surface;

[0017] 2) Pre-drill holes for installing the base assembly on the lining board in advance, place the lining board at the line marking position, directly drill holes in the wall through the holes for installing the base assembly on the lining board, insert expansion tubes, and jointly fix the base assembly and the lining board to the original wall through screws;

[0018] 3) Complete the installation of the remaining base assemblies according to the overhead height, and then fix the convex members at the preset positions on the vertical keel and the side keel of the unit frame;

[0019] 4) Insert the square rod member into the convex member, and keep it flush with the outermost edge of the convex member, and fix the two members with rivets;

[0020] 5) Align the frame base layer with the square rod member and insert it into the base member, and level it according to the finish surface line of the base layer;

[0021] 6) Complete the connection between the frame base layer assembly and the base through fasteners, and finally complete the installation of the assembled overhead base layer.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1) The base assembly adjusts the in-and-out surface of the overhead base layer in a sliding adjustment manner. The adjustment method is simple, the adjustment process has high stability, and the adjustment structure has good mechanical properties.

[0024] 2) The unit frame is installed and adjusted as a whole, and the construction is faster, which is beneficial to improving the decoration progress.
