Description

Technical Field

[0001] The present invention relates to the technical field of false walls, and in particular to a door frame structure used for false walls and the false wall. Background Art

[0002] False walls, also known as partition walls, do not bear weight, but are easier to dismantle than solid walls and are mainly used in office spaces. As a wall structure, false walls are generally made into a vertical facade that is used to divide office space. They have the advantages of sound insulation, heat insulation and thermal insulation.

[0003] A false wall usually includes a keel and wall panels. The keel is mostly made of metal and has a certain mechanical strength. The wall panels can be made of glass panels, rock panels, European pine panels or composite panels according to actual needs. For a complete false wall partition, it is generally equipped with at least one partition door. Traditional partition doors need to be installed in conjunction with door frames. Although this can achieve the installation of partition doors, there are at least the following problems: 1. During assembly, the size of the door frame needs to be completely consistent with the false wall, otherwise the door frame may not be installed correctly. If the door frame is not correct, it may cause the partition door to be difficult to install; 2. Long-term opening and closing of the partition door may cause the door frame to deform or cause the connection between the door frame and the false wall to loosen, posing a safety hazard; 3.

DETAILED DESCRIPTION

[0042] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clearly understood, the invention is further described below in conjunction with the accompanying drawings and embodiments.

[0043] Example 1

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides a top base 100, which includes a top and bottom profile 110 and elastic rubber strips 120 fixed on both sides of the top of the top and bottom profile 110. The length direction of the elastic rubber strip 120 is the same as the length direction of the top and bottom profile 110, and the top of the elastic rubber strip 120 is higher than the top of the top and bottom profile 110 when not under stress.

[0045] The top base 100 is arranged at the top and bottom of the false wall 700, and is used to fix the false wall 700 on the ceiling or floor. The elastic strip 120 has a certain elasticity. The elastic strip 120 is used as a buffer between the ceiling or floor and the top and bottom profiles 110, which can solve the problems caused by the unevenness of the ceiling or floor, increase the sealing between the ceiling or floor and the top and bottom profiles 110, improve the stability of the installation, and avoid abnormal noise.

[0046] refer to Figure 2 A fixing groove 130 is provided at the top of the top and bottom profiles 110, and the elastic strip 120 includes an elastic portion 121, a connecting portion 122 and a supporting portion 123 which are connected to each other. The elastic portion 121 is a tubular structure, and the connecting portion 122 is a strip structure. At least one group of inverted tooth-shaped mounting blocks 124 are provided on both sides of the connecting portion 122. The connecting portion 122 and the mounting blocks 124 are arranged in the fixing groove 130, and the mounting blocks 124 are against the groove wall of the fixing groove 130. The supporting portion 123 is arranged at the connecting position of the connecting portion 122 and the elastic portion 121, and is arranged outside the fixing groove 130. The bottoms of the supporting portion 123 and the elastic portion 121 are both in contact with the top of the fixing groove 130 under stress.

[0047] The elastic part 121, the connecting part 122, the supporting part 123 and the mounting block 124 are an integral structure and are all arranged along the length direction of the top and bottom profiles 110. The elastic part 121 of the tubular structure is hollow inside, which can increase the overall height of the elastic strip 120 on the one hand, and make it have better elasticity and easier to deform on the other hand.

[0048] The connecting portion 122 and the mounting block 124 are pressed into the fixing groove 130 along the opening at the top of the fixing groove 130. Since the mounting block 124 is tilted upward, the mounting block 124 is easy to enter the fixing groove 130 under pressure and is not easy to escape from the fixing groove 130, so that the elastic portion 121 can be firmly fixed on the top and bottom profiles 110. The supporting portion 123, as an extension structure of the elastic portion 121, not only increases the stability of the elastic rubber strip 120 on the top and bottom profiles 110, but also increases the contact area with the top of the fixing groove 130, thereby sharing part of the pressure for the elastic portion 121 and increasing the service life of the elastic portion 121.

[0049] The top and bottom profiles 110 are provided with a plurality of inwardly recessed V-grooves 140 . The screws can be accurately driven in by aligning the front ends of the screws with the V-grooves 140 . The V-grooves 140 serve as guides when driving the screws, preventing the screws from shaking when driving the screws.

[0050] The top and bottom profiles 110 are an integrated structure, including a first fixing platform 111, a second fixing platform 112 and a fixing arm 113. The first fixing platform 111 can be fixed to the ceiling or the floor by screws passing through the V-shaped groove 140. There are two second fixing platforms 112, which are respectively arranged on both sides of the first fixing platform 111. The height of the second fixing platform 112 is less than that of the first fixing platform 111. The keel can be fixed to the end of the second fixing platform 112 by angle brackets 150, etc. Specifically, the angle brackets 150 are provided with V-shaped brackets on the second fixing platform 112. The screws pass through the through holes and the V-grooves 140 from bottom to top in sequence, fixing the angle code 150 to the bottom surface of the end of the second fixing platform 112. At the same time, the height of the second fixing platform 112 is set to be smaller than the height of the first fixing platform 111, so that space can be provided for the angle code 150 screws to prevent the screws from being locked in place. The screws passing through the V-grooves 140 on the second fixing platform 112 cannot protrude from the first fixing platform 111, so that the screws will not interfere with the installation wall, thereby avoiding deformation of the top and bottom profiles 110.

[0051] Two elastic rubber strips 120 are respectively fixed on the outer sides of the two second fixing platforms 112, and there are two fixing arms 113, which are respectively arranged on the outer bottom sides of the two second fixing platforms 112. A foot piece 160 is fixed on the outer side of the fixing arm 113, and the connection position between the foot piece 160 and the fixing arm 113 can be broken. It should be noted that the thickness of the connection position between the foot piece 160 and the fixing arm 113 is relatively small, and can be broken or torn off with force. The height of the top and bottom profiles 110 relative to the wallboard is different when the foot piece 160 is retained and when the foot piece 160 is removed. Whether to retain the foot piece 160 can be decided according to the actual installation situation.

[0052] Working principle: first fix the connecting part 122 and the mounting block 124 in the fixing groove 130, and the supporting part 123 and the elastic part 121 located above the connecting part 122 and the mounting block 124 are arranged outside the fixing groove 130, and the bottom of the supporting part 123 and the elastic part 121 are both in contact with the top of the fixing groove 130 under stress, so that the elastic strip 120 and the top and bottom profiles 110 are fixed together, and then the top and bottom profiles 110 are fixed to the keel and wall panel through the V-shaped groove 140.

[0053] Example 2

[0054] like Figures 3 to 7As shown, the present embodiment provides a door frame structure 200 for a false wall, including a partition door 210, a door hinge 220 and two first partition units 230, an installation space for installing the partition door 210 is reserved between the two first partition units 230, the first partition unit 230 includes a first column 231, a second column 232 and two first partition wall panels 233, two first partition wall panels 233 are fixed on both sides of the first column 231 and the second column 232, the first columns 231 on the two first partition units 230 are symmetrically arranged, the first columns 231 are provided with an installation groove 240 on a side facing the partition door 210, a plurality of door hinges 220 are provided between one side of the partition door 210 and the installation groove 240, the partition door 210 and the installation groove 240 are connected to both sides of the door hinge 220, and the height of the partition door 210 is the same as the height of the first partition wall panel 233.

[0055] The first column 231 supports the first partition wallboard 233 and replaces the traditional door frame to support the partition door 210. The door frame structure 200 for the false wall eliminates the traditional door frame. The first column 231 is used as the door frame of the partition door 210, eliminating the installation steps of the traditional door frame. Moreover, since there is no obstruction of the door frame, the height of the partition door 210 can be made consistent with the height of the first partition wallboard 233, forming a vertical effect, which is more practical. At the same time, the structures of the two first columns 231 are set to be the same and symmetrical, so that the door hinge 220 can be installed on the first column 231 of any first partition unit 230, and the door opening direction can be arbitrarily specified, which is more flexible.

[0056] The first column 231 includes a first connecting column 2311 and a second connecting column 2312, one side of the first connecting column 2311 is fixed to a first partition wall panel 233, the other side of the first connecting column 2311 is fixed to one side of the second connecting column 2312, and the other side of the second connecting column 2312 is fixed to another first partition wall panel 233, two mounting grooves 240 are opened on the second connecting column 2312, one side of the door hinge 220 is fixed in one mounting groove 240, and a buffer member 250 for buffering the impact of the partition door 210 is fixed in the other mounting groove 240; avoidance grooves 260 are opened on both sides of the partition door 210, and the other side of the door hinge 220 is fixed in the avoidance groove 260.

[0057] refer to Figure 4 An avoidance groove 260 is provided on the partition door 210, and the avoidance groove 260 is used to prevent the partition door 210 from hitting the first column 231. At the same time, the first column 231 includes a first connecting column 2311 and a second connecting column 2312. The second connecting column 2312 is connected to the first partition wall panel 233 in the room. The position of the installation groove 240 can be changed on the second connecting column 2312 to form an inward opening door or an outward opening door effect.

[0058] refer to Figure 5 The second connecting column 2312 is provided with an inwardly recessed receiving groove A270 on the side facing the partition door 210, the mounting groove 240 is provided on the side of the receiving groove A270 close to the first connecting column 2311, the door hinge 220 is provided in the mounting groove 240, and the side of the partition door 210 facing the room is flush with the outer surface of the first partition wallboard 233 in the room, thereby forming an inward opening door effect. Alternatively, refer to Figure 6 The installation groove 240 is opened on the side where the second connecting column 2312 is connected to the first partition wall panel 233 facing the room, and the door hinge 220 is arranged in the installation groove 240. The side of the partition door 210 facing the room is flush with the outer surface of the first partition wall panel 233 in the room, thereby forming an outward-opening door effect.

[0059] It should be noted that, regardless of whether it is an inward-opening door or an outward-opening door, the structure of the first connecting column 2311 is the same. For the manufacturer, it is only necessary to select the corresponding second connecting column 2312 according to customer needs, which is more personalized.

[0060] The first partition unit 230 also includes two top bases 100 shown in Example 1, and the two top bases 100 are respectively fixed to the top and bottom of the first column 231 and the second column 232, and the two ends of the second fixed platform 112 are fixed to the top and bottom of the first column 231 and the second column 232 through angle codes 150.
