[0030] With the continuous improvement of material living standards, people pay more and more attention to the safety of interior decoration. The existing office area partitions are basically made of one or two layers of light steel keel gypsum board for partitions. Light steel keel gypsum board can basically only meet the needs of partitions and ordinary hanging objects. However, since the door openings need to install glass doors and fire doors, and the area and weight of the door leaves are large, the setting of the conventional light steel keel gypsum board openings cannot meet their load-bearing requirements. Long-term use will lead to reduced stability of the door frame, posing certain safety hazards.

[0031] In order to improve the stability of a door opening of a light steel frame gypsum board partition wall, the present invention provides a light steel frame gypsum board partition wall door opening reinforcement device.

[0032] Reference Figure 1 , Figure 1The structure diagram of one embodiment of the light steel keel gypsum board partition door opening reinforcement device of the present invention, in one embodiment of the present invention, the light steel keel gypsum board partition door opening reinforcement device is applied to two walls 100 arranged at intervals, each wall 100 includes a first gypsum board 110, a second gypsum board 120 and a light steel keel board 130, the wall 100 is provided with a door opening for the door frame 200 of the door leaf to be installed, and the light steel keel gypsum board partition door opening reinforcement device includes a door frame 200 and a mounting plate 300. The door frame 200 is used to be installed at the door opening position of the two walls 100, and the door frame 200 includes two opposite side columns 210. The mounting plate 300 is used to be installed against the light steel keel plate 130 of the wall 100 and connected to the side column 210. The mounting plate 300 includes a first clamping plate 310 and a second clamping plate 320. The width of the first clamping plate 310 is smaller than the width of the second clamping plate 320, and the first clamping plate 310 and the second clamping plate 320 are stacked. One end of the first clamping plate 310 is used to connect with the first gypsum board 110, and the other end of the first clamping plate 310 is connected to the side column 210; one end of the second clamping plate 320 is used to connect with the second gypsum board 120, and the other end of the second clamping plate 320 is connected to the side column 210. In addition, a telescopic member for adjusting the relative distance between the first gypsum board 110 and the second clamping plate 320 is provided.

[0033] The first clamping plate 310 and the second clamping plate 320 can be fixed by glue. In this way, the gap between the first clamping plate 310 and the second clamping plate 320 can be reduced, thereby improving the stability of the light steel keel gypsum board partition door opening reinforcement device. Of course, the first clamping plate 310 and the second clamping plate 320 can also be installed against each other by means of threaded connection, and the installation method is not limited.

[0034] In this embodiment, a protrusion is provided on one side of the second clamping plate 320 close to the first gypsum board 110, and a matching positioning groove is provided at the position of the first gypsum board 110 corresponding to the position of the protruding portion, and the protrusion is inserted into the positioning groove to fix the second clamping plate 320 and the first gypsum board 110. A compression spring can be sleeved on the protrusion to form a telescopic member. The telescopic member can open a certain gap between the second clamping plate 320 and the first gypsum board 110 so that it can be better attached to the wall, release internal stress, avoid damage to the wall due to long-term use of fire doors or glass doors, and prevent paint from falling off. Of course, in some embodiments, other telescopic structures can also be used to more appropriately fit the second clamping plate 320 and the first gypsum board 110 to reduce their internal stress.

[0035] It should be noted that the light steel keel is a metal frame for construction made of high-quality continuous hot-dip galvanized sheet as raw material and rolled by cold bending process. It is used for the shaping and decoration of non-load-bearing walls and roofs of buildings with light panels such as paper-faced gypsum board and decorative gypsum board as finishing. It is suitable for the shaping and decoration of roofs of various buildings, the basic material of the interior and exterior walls of buildings and scaffolding ceilings. Light steel keels are divided into ceiling keels and partition keels according to their uses, and are divided into V-shaped, C-shaped, T-shaped, L-shaped, and U-shaped keels according to their cross-sections. In this embodiment, the light steel keel plate 130 can select C60 light steel keel, and this type of light steel keel can meet certain strength requirements.

[0036] It is worth noting that the thickness of the first clamping plate 310 is equal to that of the first gypsum board 110, and the thickness of the second clamping plate 320 is equal to that of the second gypsum board 120. In this way, the connection strength can be improved, and it is convenient for the staff to install the clamping plates.

[0037] During installation, firstly, the first clamping plate 310 and the second clamping plate 320 are fixedly connected by bonding or screwing, and the telescopic part is installed in the corresponding installation position to complete the installation of the mounting plate 300, and then the mounting plate 300 is installed against the door opening of the wall 100 by glue or screws, and then the door frame 200 is installed on the mounting plate 300 by screws, and then the glass door or fire door required by the user can be installed.

[0038] The present invention is based on the original light steel keel gypsum board partition door opening plywood primer, and changes it to two layers of plywood around the opening partition wall (i.e., the first plywood 310 and the second plywood 320). The two plywood layers can be glued together by brushing glue, or they can be fixed by screw connection. The connection method is not limited here. In addition, because the plywood is arranged in a stepped shape (the width of the first plywood 310 is smaller than the width of the second plywood 320), the two plywoods form a staggered overlap with the contact surface of the gypsum board, thereby further strengthening the connection strength.

[0039] It can be understood that in the technical solution of the present invention, since the door frame 200 of the light steel keel gypsum board partition door opening reinforcement device is used to be installed at the door opening position of the two walls 100, the door frame 200 includes two opposite side columns 210, and its mounting plate 300 is used to be installed against the light steel keel plate 130 of the wall 100 and connected to the side column 210, and the mounting plate 300 includes a first clamping plate 310 and a second clamping plate 320, the width of the first clamping plate 310 is less than the width of the second clamping plate 320, and the first clamping plate 310 and the second clamping plate 320 are stacked, and the first clamping plate 310 is One end is used to connect with the first gypsum board 110, the other end of the first plywood 310 is connected with the side column 210, one end of the second plywood 320 is used to connect with the second gypsum board 120, the other end of the second plywood 320 is connected with the side column 210, and a telescopic member for adjusting the relative distance between the first plywood 310 and the second plywood 320 is provided, which improves the structure of the light steel keel gypsum board partition wall door opening reinforcement device, improves the load-bearing capacity of the light steel keel gypsum board partition wall door opening, improves the stability of its door frame 200, and improves the safety performance of the door frame 200 to reduce safety hazards.

[0040] In order to further enhance the stability of the light steel frame gypsum board partition door opening reinforcement device, in one embodiment, the light steel frame gypsum board partition door opening reinforcement device also includes a fixing plate 400, which is installed on the light steel keel plate 130 and is used to lock and fix the first clamping plate 310, the second clamping plate 320 and the light steel keel plate 130.

[0041] In this embodiment, a groove 131 is provided on the light steel keel plate 130 corresponding to the connection between the first clamping plate 310 and the first gypsum board 110, and the fixing plate 400 is installed in the groove 131. The groove 131 can be U-shaped, rectangular, etc., which is not limited here. It should be noted that when the board is sealed later, the force points of the screws are increased so that the first clamping plate 310 and the second clamping plate 320 are more firmly installed on the light steel keel, ensuring the stability of the glass door and the fire door in the later stage.

[0042] In one embodiment, reference Figure 1 A reinforcement portion is provided at the connection between the second clamping plate 320 and the second gypsum board 120. In this way, the connection strength can be strengthened to prevent the door frame 200 of the glass door or the fire door from falling off the wall 100, improve its safety performance, and avoid tragedy.

[0043] In the present embodiment, the reinforcement part is a notch 321 provided on the second clamping plate 320 or the second gypsum board 120, the notch 321 is arranged in a V-shape, and epoxy resin is filled in the notch 321. It is understandable that the notch 321 is arranged in a V-shape to increase the contact area between the second clamping plate 320 and the second gypsum board 120, thereby improving its stability, so as to avoid cracking or falling of the paint on the wall 100, and also to improve a certain connection strength. Of course, in some embodiments, in order to ensure the stability inside the wall 100, the above-mentioned notch 321 can also be added at the connection between the first clamping plate 310 or the second gypsum board 120 and epoxy resin can be filled in the notch 321, so as to avoid cracking or falling of the paint on the wall 100, and to improve the connection strength between the first clamping plate 310 and the first gypsum board 110.

[0044] Furthermore, in order to improve the reinforcement of the door opening of the light steel frame gypsum board partition wall, in some embodiments, an anti-crack bandage is attached to the connection position between the second clamping plate 320 and the second gypsum board 120. Similarly, an anti-crack bandage can also be attached to the connection position between the first clamping plate 310 and the first gypsum board 110 to enhance the stability inside the wall 100, thereby improving the connection strength between the first clamping plate 310 and the first gypsum board 110, and also preventing the paint of the wall 100 from cracking at the connection due to the principle of "thermal expansion and contraction".

[0045] It is worth mentioning that in order to prevent the paint on the wall 100 from cracking or falling off, a layer of 108 glue or interface agent can be applied to the surface of the second plywood 320 first, and then painted with water-based putty powder to reduce the cracking and falling of the paint.

[0046] refer to Figure 1 In some embodiments, in order to be consistent with the specifications of existing light steel frame gypsum boards to enhance their connection strength and facilitate installation, the thickness of the first plywood 310, the second plywood 320, the first gypsum board 110 and the second gypsum board 120 are all 9 mm, the thickness of the fixing plate 400 is 9 mm or 12 mm, the width of the door frame is 50 mm, and the distance between the two walls is 100 mm.

[0047] Furthermore, in order to achieve a certain connection strength, in this embodiment, the mounting plate 300 is staggered in a stepped manner so that the width of the first clamping plate 310 is smaller than the width of the second clamping plate 320. The width of the first clamping plate 310 is 300 mm, and the width of the second clamping plate 320 is 400 mm, that is, the width of the contact surface between the first clamping plate 310 and the light steel keel plate 130 is 300 mm, the width of the contact surface between the second clamping plate 320 and the first gypsum board 110 is 100 mm, and the width of the contact surface between the first clamping plate 310 and the second clamping plate 320 is also 300 mm. Of course, in other embodiments, it may be necessary to install heavier or lighter glass doors or fire doors, etc., and the size of the staggered overlapping mounting cavity can also be adjusted, and the first clamping plate 310 and the second clamping plate 320 of corresponding sizes can be made, and then the required connection strength can be achieved by adjusting their contact surfaces. Here, the sizes of the first clamping plate 310 and the second clamping plate 320 are not limited.

[0048] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
