Description

Side frame base of door frame

The invention belongs to the technical field of a combined door frame assembly, in particular to a side frame base body capable of simply cutting and cutting the door frame in the field, so that two L-shaped side frame strips can be simultaneously produced after cutting, and the applicability is achieved. Maximum, simple construction, fast production and reduced cost.

According to the continuous renovation of the building technology, the early door frames need to be erected in the predetermined position before the grouting, or the brick wall and other partition walls can be started. This causes great inconvenience and trouble to the partition wall. The calculation of the size error causes the wall edge not to be completely integrated with the door frame, which affects the fixing of the door frame and the strength of the wall after construction, and even damages the door frame due to improper collision during the construction process. In recent years, in order to increase the diversification and variability of space applications within the building, most of them have recently adopted a modular door frame, which forms a reserved hole for the door frame on the wall during construction, and then installs the door frame after the scene; In recent years, after being widely used, the door frame is mainly made of solid wood planing or hard PVC. For example, as shown in Figure 1 (A), in the case of solid wood door frame (1), it is tied to a solid wood planer. The two side wall surfaces of the main frame strip (100) are respectively formed with a corresponding embedded slot (101) for respectively embedding a planed L-shaped solid wood side frame strip (105), and the side frame When the strip (105) is produced, as shown in Figure 1 (B), it is first selected from square wooden strips (A), after flattening and polishing, The mechanical tool shaves off the excess portion (B) to form an L-shaped side frame strip (105) for forming a solid wood door frame (1) in cooperation with the main frame strip (100), such that the side frame strip (105) is shaved off The wood is often more than left, and the molding process is cumbersome. It is necessary to repeat the polishing, dyeing, painting and painting before the finished product, and increase the labor cost. The use of wood is also a kind of destruction and waste to the environmental resources; In addition, as shown in FIG. 2(A), the door frame (2) extruded by PVC is formed on a side wall surface of a hollow main frame strip (200) extruded from a PVC to form a corresponding embedded slot ( 201), for respectively inserting a PVC extruded hollow L-shaped side frame strip (205), and when the side frame strips (205) are pressed out, the inserting portion is fixed in size and cannot be wall-mounted The thickness can be adjusted arbitrarily, so many thicker walls are not applicable. The manufacturer often needs to prepare a variety of side frame strips (205A, 205B, 205C). As shown in Figure 2 (B), the cost is wasteful. Stock pressure on stock preparation, and on-site cutting is not easy.

In other words, in the case of on-site installation and construction, once the shape of the wall or the thickness of the wall is not the original design size, the side frame of the existing door frame cannot be effectively adjusted, and its versatility is extremely poor, so that it can be installed and constructed. Due to considerable restrictions, even the construction personnel can not smoothly carry out the installation work, affecting the convenience and applicability of the installation and application, how to solve the above problems, is the industry to be developed and overcome.

In view of this, the inventors have discussed the shortcomings and problems faced by the existing rear-mounted modular door frames, and have been developing and manufacturing experience in related technical fields for many years. After long-term continuous research and trial work, the inventors have finally succeeded in developing. A side frame base of a door frame, in order to overcome the inconvenience and trouble caused by the existing door frame.

Therefore, the main object of the present invention is to provide a side frame base body of a door frame, thereby satisfying different wall thicknesses and the need for left and right asymmetry, so as to improve the convenience and applicability of the door frame installation.

Further, the second main object of the present invention is to provide a side frame base body of a door frame which can be quickly cut in the field, which facilitates the installation work and can improve its practicability.

The present invention mainly realizes the foregoing objects and effects through the following technical means: the side frame base system is a molded ㄇ shape which is formed by extrusion of a PVC foaming material, and can be cut into two pieces by simple cutting in the field. The side frame strips of the side frame strips can be respectively embedded in the two sides of the main frame strips to form a door frame for mounting the reserved holes of the wall door frame, wherein the side frame base body The utility model has a cross bar segment and two straight bar segments respectively formed at two ends of the cross bar segment, and at least one outer cutting and folding opening is formed on the outer surface of the cross bar segment of the side frame base body, and the cross bar segment is formed on both sides of the straight bar The inner side surface of the segment is formed with at least one inner cutting edge corresponding to the outer cutting and folding opening, and the side frame base body can be folded and folded by the inner and outer cutting and folding edges to form two L-shaped side frame strips.

Therefore, through the specific implementation of the above technical means, the side frame base body of the door frame of the present invention can form two L-shaped side frame strips by using the inner and outer cutting and folding openings, respectively, for respectively inserting into the left side of a main frame strip. Right side, to facilitate the installation of the door frame reserved holes for different wall thicknesses, and the left and right side frame strips need to be asymmetrical, which can improve the convenience and applicability of the door frame installation, and enhance the Its practicality can further increase the added value of products and enhance its economic benefits.
