Light steel keel for assembled door pocket

Abstract

The present invention is a light steel keel used for an assembled door cover. There are several assembly holes for fixing the base plate on the upper and lower sides of the front of the light steel keel, and several operation holes are opened on the upper surface of the light steel keel; The back of the light steel keel is provided with a number of fixing parts for fastening the keel and the wall A. The shape of the keel is like or like, like, like, like. Advantages: No special tools are required for installation, the whole installation process is simple and convenient, and the door cover and the wall are fixed reliably; because the shape of the light steel keel is round, the protruding steel part and the groove on the back of the wooden molding are tightly matched, stable , strong; simplified production process, convenient operation, improved work efficiency, low production cost; the frame made of light steel, the door pocket has high horizontal and vertical degrees, flat and firm, and is not easy to deform. The door cover is easy to assemble, saves labor and materials, saves a lot of wood, and realizes industrialized mass production.

Description

technical field [0001] The invention relates to a light steel keel used for an assembled door pocket, and belongs to the technical field of decorative materials. Background technique [0002] In the prior art, light steel keel is not used to install the door cover. When installing the door cover, first open and plan the door frame material 50mm×100mm×2000mm and nail it into the door frame structure with iron nails, then put the wires on the wall, punch holes with an electric hammer, Make a cork, and fix the door frame with big iron nails, put the wire on the corresponding position of the door frame, drill a hole with an electric hammer, drive in the cork, nail a 40mm×50mm×2000mm wooden square, and then place the wire between the wooden square and the wooden square Nail the base board of the corresponding size, and finally paste the cut panel. Its shortcoming is that it is labor-intensive and material-consuming, and the loss rate reaches more than 5%. There are many holes a...

However, when it is installed, the light steel keel and the wall are fixed with externally screwed expansion screws. The specific method is to first insert all the expansion screws into the wall, and then push the door cover as a whole into the reserved installation position of the door cover. , through the operation hole on the light steel keel, the screw rod in the expansion screw must be sucked out with a magnet, and a special tool must be used to put a fixing piece and a nut on the operation hole. It is more difficult to screw on the nut, and the installation quality cannot be guaranteed at the same time, and the work efficiency is low

[0004] In addition, the combination of the door cover line and the light steel keel is to use U-shaped steel tape glue to embed in the wooden line, and combine this line with the light steel keel with magnets and then glue it. This method is due to the wooden line U-shaped bar steel is embedded with glue on the back, and a strong magnet or magnetized keel must be placed on the keel, which not only increases the installation process, but also increases the production cost
