Description

Technical Field

[0001] The utility model relates to the field of building partition wall structures, in particular to a fixed connection structure of a lightweight partition wall system. Background Art

[0002] Partition walls are walls that separate the interior spaces of a building. The basic requirements for partition walls are that they should be small in weight to reduce the load on the floor and slab; thin in thickness to increase the usable area of ​​the building; and soundproof, water-resistant, fire-resistant, etc. according to specific environmental requirements. Considering that the division of rooms changes with the use requirements, partition walls should be as easy to disassemble and assemble as possible.

[0003] When installing a lightweight partition wall, it is necessary to fix the lightweight partition wall with the help of a clamp so that it is fixedly connected to the main wall or structural column and other building walls to avoid relative movement. Currently, a U-shaped clamp is often used. The bottom surface of the U-shaped clamp is provided with a screw hole. The screw passes through the screw hole to lock and fix the U-shaped clamp on the main wall or structural column, and then the edge of the lightweight partition wall is inserted and tightly fitted into the U-shaped groove of the U-shaped clamp. The existing fixed connection structure of this lightweight partition wall is simple, and the connection firmness is poor. Utility Model Content

[0004] The first object of the utility model is to provide a fixed connection structure of a lightweight partition wall system to improve the connection firmness of the lightweight partition wall.

[0005] A fixed connection structure of a lightweight partition wall system comprises a lightweight partition wall and a U-shaped clip, wherein a screw hole is provided on the bottom surface of the U-shaped clip, and a screw passes through the screw hole of the U-shaped clip from the inside to the outside and is nailed into the building wall to fix the U-shaped clip; the lightweight partition wall is inserted into the U-shaped clip, and a layer of anti-cracking mortar layer is filled on the inner bottom of the U-shaped clip, and the lightweight partition wall is inserted into the U-shaped clip and pressed on the anti-cracking mortar layer, and the bonding and fixation between the lightweight partition wall and the U-shaped clip is achieved through the anti-cracking mortar layer; a through hole is also provided on the bottom surface of the U-shaped clip, and the anti-cracking mortar layer can enter the through hole and fill the through hole under the pressing force of the lightweight partition wall.

[0006] After the lightweight partition wall of the utility model is inserted into the U-shaped clip, an anti-cracking mortar layer is sandwiched between the U-shaped clip and the lightweight partition wall, and after the anti-cracking mortar layer is cured, the U-shaped clip and the lightweight partition wall are fixed. Compared with the lightweight partition wall and the U-shaped clip in the prior art that are fixed by tight fit, the pressure of size adaptation between the lightweight partition wall and the U-shaped clip is reduced, and the lightweight partition wall is easier to insert into the U-shaped clip, and the lightweight partition wall is fixed more firmly. In addition, when the anti-cracking mortar with a certain fluidity is filled into the U-shaped clip, the anti-cracking mortar will be embedded in the through hole and contact with the building wall outside the through hole. Since the U-shaped clip is a steel component, the bonding firmness of the anti-cracking mortar to the building wall is usually stronger than its bonding firmness to the steel component, thereby further strengthening the fixing effect of the lightweight partition wall.

[0007] Furthermore, the through holes preferably have an even number and are arranged in pairs; each pair of the through holes is in an eight-shaped shape.

[0008] Furthermore, a first finishing layer is attached to the building wall surface, and a second finishing layer is attached to the wall surface of the lightweight partition wall. The first finishing layer and the second finishing layer are connected at the connection position between the building wall surface and the lightweight partition wall. The fixed connection structure of the lightweight partition wall system also includes an alkali-resistant glass fiber cloth, and the alkali-resistant glass fiber cloth is composed of a first embedded part located inside the first finishing layer and a second embedded part located inside the second finishing layer. The alkali-resistant glass fiber cloth is embedded inside the first finishing layer and the second finishing layer and connects the two, so that the connection between the first finishing layer and the second finishing layer is not easy to crack. In the specific implementation process, the alkali-resistant glass fiber cloth is preferably composed of two or three layers of alkali-resistant glass fiber cloth units stacked together.

[0009] Furthermore, a leveling layer is bonded to the building wall, and the bottom surface of the U-shaped clip is bonded and fixed to the leveling layer. The leveling layer is also bonded with an insulation layer and a first finishing layer in sequence, and the insulation layer is an L-shaped structure consisting of a first insulation part bonded to the leveling layer and a second insulation part bonded to the lightweight partition wall; a second finishing layer is bonded to the wall of the lightweight partition wall, and the first finishing layer extends along the outer wall of the insulation layer toward the lightweight partition wall until it is connected to the second finishing layer, which facilitates the installation of the U-shaped clip and can also improve the insulation effect of the connection between the building wall and the lightweight partition wall.

[0016] The following is a detailed description of the specific implementation of the fixed connection structure of the lightweight partition wall system of the utility model in conjunction with the accompanying drawings: Example 1

[0017] Combination Figure 1 , Figure 4 and Figure 6 When the building wall 100 is a regular vertical surface and the distance between the building wall 100 and the lightweight partition wall 10 is small, the fixed connection structure of the lightweight partition wall system includes the lightweight partition wall 10 and the U-shaped clip 20. The bottom surface of the U-shaped clip 20 is provided with a screw hole 30. A screw 40 passes through the screw hole 30 of the U-shaped clip 20 from the inside to the outside and is nailed into the building wall 100 to fix the U-shaped clip 20. The lightweight partition wall 10 is inserted into the U-shaped clip 20. , the inner bottom of the U-shaped card 20 is filled with a layer of anti-cracking mortar layer 50; the lightweight partition wall is inserted into the U-shaped card and pressed against the anti-cracking mortar layer 50, and the lightweight partition wall 10 and the U-shaped card 20 are bonded and fixed by the anti-cracking mortar layer 50; a through hole 200 is also opened on the bottom surface of the U-shaped card 20, and the anti-cracking mortar layer 50 will enter the through hole 200 under the pressing force of the lightweight partition wall 10 and fill the through hole 200;

[0018] A first finishing layer 60 is bonded to the building wall surface 100, and a second finishing layer 70 is bonded to the wall surface of the lightweight partition wall 10. The first finishing layer 60 and the second finishing layer 70 are connected at the connection position between the building wall surface 100 and the lightweight partition wall 10. The fixed connection structure of the lightweight partition wall system also includes an alkali-resistant glass fiber cloth 80, and the alkali-resistant glass fiber cloth 80 is composed of a first embedded part 81 located inside the first finishing layer 60 and a second embedded part 82 located inside the second finishing layer 70. Example 2

[0019] like Figure 2 As shown, the fixed connection structure of the lightweight partition wall system is used when the building wall 100 is of a special shape and the distance between the building wall 100 and the lightweight partition wall 10 is relatively small. Example 3

[0020] Combination Figure 3 , Figure 4 and Figure 6 When the building 100 has an insulation layer, the fixed connection structure of the lightweight partition wall system is different from that of Example 1 in that:

[0021] A leveling layer 90 is bonded to the building wall 100, and the bottom surface of the U-shaped clip 20 is bonded and fixed to the leveling layer 90. An insulation layer 110 and the first finishing layer 60 are sequentially bonded to the leveling layer 90. The insulation layer 110 is an L-shaped structure consisting of a first insulation part 111 bonded to the leveling layer 90 and a second insulation part 112 bonded to the lightweight 10. A second finishing layer 70 is bonded to the wall of the lightweight partition wall 10, and the first finishing layer 60 extends along the outer wall of the insulation layer 110 toward the lightweight partition wall 10 until it is connected to the second finishing layer 70.

[0022] After the lightweight partition wall 10 of the fixed connection structure of the lightweight partition wall system of Examples 1 to 3 is inserted into the U-shaped clip 20 and fixed by the anti-cracking mortar layer 50, compared with the lightweight partition wall 10 and the U-shaped clip 20 in the prior art, there is no need for interference fit between the lightweight partition wall 10 and the U-shaped clip 20, making it easier to insert the lightweight partition wall 10 into the U-shaped clip 20, and at the same time, the lightweight partition wall 10 can also be fixed. At the same time, the alkali-resistant glass fiber cloth 80 is pre-embedded in the first finishing layer 60 and the second finishing layer 70 and connects the two, so that the connection between the first finishing layer 60 and the second finishing layer 70 is not easy to crack. Moreover, when anti-cracking mortar with a certain fluidity is filled into the U-shaped clip 20, the anti-cracking mortar will be embedded in the through hole 200 and contact the building wall 100 outside the through hole 200. Since the U-shaped clip 20 is a steel component, the bonding strength of the anti-cracking mortar to the building wall 100 is usually stronger than its bonding strength to the steel component, thereby further enhancing the fixing effect of the lightweight partition wall 10.

[0023] Of course, the fixed connection structure of the lightweight partition wall system of the utility model only needs to have the structure of "the lightweight partition wall 10 is inserted and matched in the U-shaped clip 20, the inner bottom of the U-shaped clip 20 is filled with a layer of anti-cracking mortar layer 50, the lightweight partition wall 10 is inserted in the U-shaped clip 20 and pressed on the anti-cracking mortar layer 50, and the lightweight partition wall 10 and the U-shaped clip 20 are bonded and fixed by the anti-cracking mortar layer 50, and the bottom surface of the U-shaped clip 20 is also provided with a through hole 200" to achieve the technical effect of "the lightweight partition wall 10 is well fixed". The structure of "the first finishing layer 60 and the second finishing layer 70 are jointly embedded with alkali-resistant glass fiber cloth 80" further gives the fixed connection structure of the lightweight partition wall system the technical effect of "anti-cracking at the connection".

[0024] Embodiments 1 to 3 can be improved as follows:

[0025] (1) If Figure 5 As shown, the alkali-resistant glass fiber cloth 80 is preferably formed by stacking two or three layers of alkali-resistant glass fiber cloth units (i.e., a two-layer or three-layer structure). Of course, the number of layers of the alkali-resistant glass fiber cloth 80 can be adjusted according to needs and actual conditions, for example, it can also be a single-layer structure.

[0026] (2) If Figure 4 As shown, the through holes 200 have an even number and are arranged in pairs; each pair of through holes 200 is in an 8-shaped shape. Of course, the shape and distribution structure of the U-shaped clamp 20 are not limited to the specific shapes and distribution structures shown in the drawings.

[0027] The lightweight partition wall 10 may be a composite board of concrete and foam particles.

[0028] The screw 40 of the present invention can be an existing expansion screw or a self-tapping screw.

[0029] The building wall surface 100 of the present invention refers to: a wall surface of a building structure such as a main wall or a column (including a structural column).

[0030] 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.
