Description

Technical Field

[0001] The utility model relates to the technical field of indoor suspended ceilings, in particular to a suspended ceiling anti-cracking structure. Background Art

[0002] The suspended ceiling is an important part of interior decoration. Most of the existing suspended ceilings use light steel keels to install and fix the ceiling panels. However, due to the use of keels for installation, the force on the top wall is uneven. After long-term use, the corners of the suspended ceiling are prone to deformation, causing cracks in the wall, which not only affects the beauty of the decoration, but also poses a greater safety hazard. Therefore, it is necessary to improve it.

[0003] In current construction, the main method to prevent cracking at the corners of suspended ceilings is to use an L-shaped wood board for reinforcement, then clamp the two ends of the wood board with side keels, and then use secondary keels to support the side keels for reinforcement, and then ensure that there is no gap between the secondary keel and the side keel.

[0004] The existing construction method avoids cracking at the corners of the suspended ceiling in a short period of time. However, during decoration, the decoration master needs to cut out the "L"-shaped plate that meets the requirements in advance according to the size of the corner of the suspended ceiling, which increases the construction steps to a certain extent, prolongs the construction period, and places higher requirements on the decoration master's decoration skills. Moreover, due to the large area of ​​the "L"-shaped plate and being in a humid environment for a long time, the "L"-shaped plate at the corner is prone to deformation, resulting in uneven force and different torque at both ends of the plate, so there is still a risk of cracking. Utility Model Content

[0005] The utility model aims to provide a suspended ceiling anti-cracking structure, which solves the defect that an "L"-shaped plate at a corner of an existing suspended ceiling cracks and deforms due to uneven force, thus affecting the appearance.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: the utility model provides a ceiling anti-cracking structure, which includes:

[0011] A lever plate is height-adjustably arranged between the main side dragon group and the secondary side dragon group.

[0012] Optimally, the main side dragon group includes a first main side dragon fixed on the inner side of the first wall and a second main side dragon fixed on the inner side of the second wall, and the first main side dragon is perpendicular to the second main side dragon.

[0013] Optimally, the secondary side dragon group includes a first secondary side dragon and a second secondary side dragon fixed to the first secondary side dragon, the first secondary side dragon is parallel to the first main side dragon, and the second secondary side dragon is parallel to the second main side dragon.

[0014] Optimally, it also includes an adjustment hole opened on the top of the lever plate, a hanger fixed in the adjustment hole, a splicing plate fixed on both sides of the lever plate, and a diagonal brace keel fixed between the main side dragon group and the secondary side dragon group.

[0015] Optimally, the lever plate has a first vertical side and a second vertical side that are perpendicular to each other and a hypotenuse connecting the first vertical side and the second vertical side, the first vertical side is fixed to the bottom of the first main side dragon, the second vertical side is fixed to the bottom of the second main side dragon, and the hypotenuse is fixed to the bottom of the secondary side dragon group.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment 1

[0034] The utility model ceiling crack prevention structure comprises a first wall 1, a second wall 2, a main side dragon group, a secondary side dragon group, a lever plate 7, an adjustment hole 8, a diagonal keel 9, a splicing plate 10 and a suspension rod 11. The first wall 1 and the second wall 2 are formed by pouring concrete and are arranged perpendicular to each other. Above the first wall 1 and the second wall 2 is a roof ceiling structure for fixing and installing keels and other hanging parts.

[0035] like Figure 1 , 2 As shown, the main side dragon group includes a first main side dragon 3 and a second main side dragon 4. The first main side dragon 3 is fixed on the inner side of the first wall 1, and the second main side dragon 4 is fixed on the inner side of the second wall 2. The first main side dragon 3 and the second main side dragon 4 are arranged vertically and the first main side dragon 3 and the second main side dragon 4 are in an "L" shape.

[0036] The secondary side dragon group is fixed to the inner side of the main side dragon group through the diagonal brace 9, and the secondary side dragon group includes a first secondary side dragon 5 and a second secondary side dragon 6. The first secondary side dragon 5 is parallel to the first main side dragon 3, and the second secondary side dragon 6 is parallel to the second main side dragon 4. The first secondary side dragon 5 and the second secondary side dragon 6 are vertically fixed and form an "L" shape.

[0037] The main side dragon group and the secondary side dragon group are both set to be "L" shaped, so that an "L" shaped channel is formed between the two, and the bar plate 7 and the splicing plate 10 are fixed at the bottom of the "L" shaped channel, and then the lower surface of the bar plate 7 and the splicing plate 10 is scraped. The setting of the "L" shaped channel provides an avoidance space for the installation of the suspension rod 11.

[0038] The diagonal brace 9 is fixed between the main side keel group and the secondary side keel group, and is used to fix the connection between the main side keel group and the secondary side keel group, thereby improving the reliability of the fixed connection between the main side keel group and the secondary side keel group (the top of the main side keel group and the secondary side keel group are fixedly connected to the ceiling of the roof through the main keel).

[0039] like Figure 4 As shown, it is a schematic diagram of the structure of the lever plate 7, and the lever plate 7 is fixed at the corner of the "L"-shaped channel. The lever plate 7 is an isosceles right triangle plate, that is, the lever plate 7 has a first vertical side 701, a second vertical side 702 and a hypotenuse 703. The first vertical side 701 is fixed to the first main side dragon 3, and the second vertical side 702 is fixed to the second main side dragon 4. The hypotenuse 703 is used to connect the first vertical side 701 and the second vertical side 702 (because the lever plate 7 is an isosceles right triangle plate, the angle between the hypotenuse 703 and the first vertical side 701 is 45°).

[0040] The lever plate 7 is designed to be in the shape of an isosceles right triangle. First, the triangle has better stability. Moreover, the angles on both sides of the lever plate 7 are the same, so the force after fixation is more uniform and not prone to cracking and deformation. Compared with the existing "L"-shaped plate fixing method, the construction difficulty is lower, the plate is easier to process and fix and install, and the triangular lever plate 7 has a smaller area and is not prone to deformation.

[0041] The splicing plates 10 are fixed on both sides of the bar plate 7 in a shape-matched manner, ensuring that there is no gap between the splicing plates 10 and the bar plate 7 .

[0042] The oblique bracing keel 9 is fixed obliquely between the first main side keel 3 and the first secondary side keel 5 (or the second main side keel 4 and the second secondary side keel 6), and the angle between the oblique bracing keel 9 and the first main side keel 3 is 45°. On the one hand, it can increase the contact area with the first main side keel 3 and the first secondary side keel 5, and improve the firmness of the fixation between the two; on the other hand, the distribution of the oblique bracing keel 9 is also more uniform.

[0043] The adjustment hole 8 is formed at the top of the lever plate 7, and the depth of the adjustment hole 8 is half the thickness of the lever plate 7 (in this embodiment, the thickness of the lever plate 7 is 1.8 cm, and the depth of the adjustment hole 8 is 0.9 cm). The design of half the depth of the adjustment hole 8 can meet the fixation of the suspension rod 11, and will not affect the structural strength of the lever plate 7, so as to avoid the adjustment hole 8 being too deep, which may cause the lever plate 7 to crack and deform.

[0044] like Figure 3 As shown, the ferrule 12 is fixed to the ceiling structure of the roof by screwing, and the interior of the ferrule 12 is a hollow structure, which is convenient for the passage and fixation of the hanger 11 (the ferrule 12 is in the shape of a "□", and the screw passes through the ferrule 12 and is fixed to the ceiling structure of the roof).

[0045] The outer peripheral surface of the suspension rod 11 is provided with an external thread, the lower end of the suspension rod 11 is screwed into the adjustment hole 8, and then the lower locking nut 13 is screwed against the lever plate 7 to complete the fixation of the suspension rod 11 and the lever plate 7.

[0046] A through hole with a diameter slightly larger than the outer diameter of the suspension rod 11 is provided on the ferrule 12. The top of the suspension rod 11 passes through the through hole of the ferrule 12, and then the upper locking nut 14 is screwed against the upper and lower sides of the ferrule 12 respectively to fix the suspension rod 11 (because the diameter of the through hole on the ferrule 12 is slightly larger than the outer diameter of the suspension rod 11, the suspension rod 11 can freely adjust its height in the ferrule 12).

[0047] During actual adjustment, the height of the suspension rod 11 and the lever plate 7 can be appropriately adjusted by loosening the locking nut 14, which can give the lever plate 7 an upward force to prevent the lever plate 7 from deforming, making the forces on both ends more evenly and reducing the risk of cracking at the corners.

[0048] like Figure 1 As shown, the projection of the adjustment hole 8 on the lever plate 7 falls on the symmetry axis of the lever plate 7, that is, on the height of the hypotenuse of the isosceles right triangle. The suspension rod 11 is suspended from the middle of the lever plate 7 so that the forces on both ends of the lever plate 7 are more evenly distributed to reduce the risk of cracking at the corners.

[0049] Embodiment 2

[0050] like Figure 2 As shown, the technical solution in the second embodiment is different from that in the first embodiment only in the position of the adjustment hole 8. In this embodiment, the projection of the adjustment hole 8 on the lever plate 7 is symmetrically arranged on both sides of the symmetry axis of the lever plate 7. That is, the suspension rod 11 is suspended from both sides of the lever plate 7, and the suspension positions are symmetrical to each other, which can improve the firmness of the lever plate and prevent the lever plate 7 from being deformed, and at the same time make the forces on both ends of the lever plate 7 more uniform, so as to reduce the risk of cracking at the corners.

[0051] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
