Description

Technical Field

[0001] The utility model relates to the field of building partition wall structures, in particular to a connection structure between a wall and a door frame. Background Art

[0002] Lightweight partition walls refer to non-load-bearing lightweight interior partition walls. This type of partition wall is characterized by light weight, thin wall, easy disassembly and assembly, energy saving and environmental protection, and is conducive to industrialized construction of buildings. When installing door frames on lightweight partition boards, screws are often used for fixing. The specific steps are as follows: first, make reserved holes in four positions of the door frame, then place the door frame on the wall, and fix the door frame to the reserved holes with screws. However, this method is prone to damage the lightweight partition wall when nailing in the screws, and it is not easy to detect when the damage to the lightweight partition wall is not obvious, which poses a safety hazard.

In addition, once cracking is found when opening holes in the lightweight partition wall 11 or the door frame 20, it can be discovered in time, which is conducive to eliminating hidden dangers. In addition, the second long hole 200 and the second straight arm 32 are inclined and plugged into each other. When the depth of the steel bar 30 inserted into the door frame 20 is equal, the connection structure of the utility model can maximize the length of the second straight arm 32 embedded in the door frame 20 and increase the contact area between the steel bar 30 and the door frame 20, thereby strengthening the connection firmness between the lightweight partition wall 11 and the door frame 20. At the same time, the connection structure of the wall and the door frame of Example 2 can provide a pulling effect for the lightweight partition wall 11 and the door frame 20 in multiple directions, thereby improving the seismic performance.

[0020] Of course, the number of the steel bars 30 is not limited to the number shown in the drawings, and the specific number can be freely adjusted according to the height of the wall.

[0021] Furthermore, the outer diameter of the first straight arm 31 is slightly smaller than the aperture of the first long hole 110 ; the outer diameter of the second straight arm 32 is slightly smaller than the aperture of the second long hole 200 .

[0023] Further, such as Figure 1 and Figure 3As shown, when the wall 10 is a high sound insulation wall, the connection structure between the wall 10 and the door frame 20 is as follows: the wall 10 also includes a sound insulation layer 12 and a decorative wallboard 13 which are sequentially arranged on the outside of the lightweight partition wall 11 along the wall thickness direction; a vertical keel 40 is sandwiched between the sound insulation layer 12 and the door frame 20; a first screw hole is opened on the vertical keel 40 along the wall thickness direction; a long screw 50 passes through the first screw hole and is nailed into the lightweight partition wall 11 to realize the locking connection between the vertical keel 40 and the lightweight partition wall 11; a positioning seal 60 is sandwiched between the decorative wallboard 13 and the door frame 20; a second screw hole is opened on the positioning seal 60 along the wall thickness direction; a first screw hole is opened on the vertical keel 40 to connect with the vertical keel 40 ... The third screw hole is aligned with the second screw hole, and the locking screw 70 passes through the second screw hole and the third screw hole in sequence and cooperates with the thread of the third screw hole to realize the locking connection between the positioning seal 60 and the vertical keel 40; the positioning seal 60 is a U-shaped strip with an opening facing away from the lightweight partition wall 11; the outer edges of the U-shaped end arms of the U-shaped strip are bent outward 90° and extended to form two corresponding folded edges (61, 62), wherein one of the folded edges 61 and the corresponding end arm enclose a decorative wallboard fixing groove for the edge of the decorative wallboard 13 to be inserted and fixed therein, and the other folded edge 62 and the corresponding end arm 62 enclose a door frame fixing groove for the edge of the door frame 20 to be inserted and fixed therein. The utility model realizes the fixed connection between the longitudinal keel 40 and the lightweight partition wall 11 by the long screw 50, and then realizes the fixed connection between the positioning seal 60 and the longitudinal keel 40 by the locking screw 70, and then realizes the fixation of the edge of the door frame 20 by the matching structure between the positioning seal 60 and the door frame 20. Compared with the edge of the door frame 20 being fixed and attached to the wall 10 only by bonding, the utility model has a better fixing effect on the door frame 20. Of course, the edge of the door frame 20 can also be fixedly connected to the wall 10 by existing bonding and other methods. At the same time, the lightweight partition wall 11 can be provided with the sound insulation layer 12 and the decorative wallboard 13 on only one side in the thickness direction thereof, or the sound insulation layer 12 and the decorative wallboard 13 can be symmetrically provided on both sides in the thickness direction thereof.

[0024] The lightweight partition wall 11 may be a composite board of concrete and foam particles.

[0025] For ordinary technicians in the technical field to which the utility model belongs, the utility model can make several simple deductions or substitutions without departing from the concept of the utility model, which should be regarded as falling within the protection scope of the utility model.
