Abstract

The present invention is designed to firmly fix the door frame inside the apartment to the building structure. When constructing the reinforced concrete structure, when the formwork is installed before the concrete is laid, the female thread of plastic material is fixed to the inner side of the formwork with the nail to pour the concrete. When installing the next door frame, it is designed to secure the quality that can be installed firmly in the correct position by forming a support point in the structure and prevent the defect such as the door frame falling from the structure over time after moving into the apartment.

This design requires more precise construction when installing the structure than the existing door frame fixing method, but it will show superior strength than the existing construction methods such as punching a female screw with a hammer by a drill after casting concrete. It is judged and designed to prevent the defect that occurs when opening and closing the door.

Description

Door frame adjustment mechanism

The present invention relates to an adjustment for fixing the door frame, and more particularly to an adjustment mechanism for adjusting the horizontal and vertical of the door frame.

In general, in the case of the door frame by drilling a hole in the concrete and hit the plastic cap with a hammer and fixed it by a construction method such as fixing the door frame or hammering with a hammer using a concrete nail directly to the door frame.

However, most of the defects of the building door frame are poorly settled, causing the space between the door frame and the structure to rise or the vibration of the door opening and closing, causing fear of building safety of the insider, or even fixing the door frame because the door frame is not properly fixed. There are many cases of various defects such as the inability to close or close the door due to the distortion caused by the change in the moisture content of the material.

The purpose of the present invention is a mechanism that can adjust the horizontal and vertical when fixing the door frame inside the building. When installing the formwork before placing concrete, install the plate and pvc cap to pre-buy it and there is no damage of the structure. Easy to adjust is to prevent defects due to poor door frame installation.

The present invention is to install the plate and pvc cap in advance when installing the formwork after the reinforcement when the reinforced concrete structure as shown in Figure 2 in order to firmly adjust and adjust the door frame inside the building to the building structure, and the concrete curing and concrete curing and It is an idea to secure the horizontal and vertical of the door frame in the door frame installation process after removing the formwork.

Referring to the accompanying drawings a preferred use of the present invention as follows.

Figure 2 is intended to show the role of the adjust tool in the overall door frame to show the adjustment of the horizontal and vertical when the door frame fixed by using the locking and unlocking of the adjustment bolt on the plate pre-buried in the structure. Compared to the fixing method, the process is cumbersome, but it is a devised design for the correct installation of the door frame, which is a great addition to the building door frame installation and quality maintenance.

According to the present invention as described above by allowing the building to adjust the horizontal and vertical of the door frame,

It will help to improve the quality of the building, which can prevent the obstacles caused by the door frame being tilted or tilted when the door is opened or closed, or to prevent the defect caused by the door frame falling off the structure.

Claims (1)

When fixing the door frame, install the plate and plastic lid on the formwork before placing the concrete and fasten the bolt to the female threaded plate after removing the formwork through the concrete pouring and curing process. Door frame adjustment mechanism for leveling.
