Description

TECHNICAL FIELD

[0001] The present application belongs to the general building construction technical field, and particularly relates to a floor slab characterized by a supporting structure, and particularly relates to a fabricated double-misaligned grade drop ceiling. BACKGROUND

[0002] Ceiling is a kind of decoration of the top decoration of the living environment of a house. Simply speaking, it refers to the decoration of the ceiling. The drop ceiling is one of the ceilings, which refers to the ceiling that is not in the same plane and similar to the ladder. For example, CN209457240U shows a modeling card type furring drop ceiling, in which the modeling card type furring system is mainly a panel, and an L-shaped ladder shape is formed by combining a corner furring and a shadow corner furring. This ladder shape applied to a home environment will give people a commercial feeling, making the whole room look very commercial. Among many designs, the ceiling with curves, that is, the arc line is vertically made on the design of the shed roof. Such a design method can make the cold house much warmer and softer, and such a design is more suitable for soft decoration styles, such as a rural style and an American style.

[0003] However, another problem brought by the arc ceiling is that the vertical projections of the upper and lower panels do not coincide, which will increase the probability of misalignment during installation. SUMMARY

[0004] The present application provides a fabricated double-misaligned grade drop ceiling, and one of the purposes of the present application is to provide a grade drop ceiling with an arc-shaped corner side.

[0005] The second purpose of the present application is to improve the accuracy of the installation process of the drop ceiling.

[0006] The technical scheme adopted by the present application to solve the above problems is: a fabricated double-misaligned grade drop ceiling, at least having an arc-shaped corner, comprising:

[0007] a high-position plate;

[0008] a low-position plate;

[0009] a fixing member, the upper end of which is used to connect the high-position plate and the lower end of which is used to connect the low-position plate;

[0010] wherein the low-position plate is provided with a displacement hole body used to connect the fixing member, the displacement hole body is movable along the horizontal direction perpendicular to the fixing member, and is fixed at the relative position of the low-position plate when the fixing member is connected with the low-position plate.

[0011] The arc-shaped corner is an arc-shaped plate used to connect the high-position plate and the low-position plate, and the concave surface faces the fixing member.

[0012] The offset hole allows the lower plate to adjust its position according to the curvature of the curved plate, and the offset hole can also adjust its relative position with the fixing component, ensuring the accuracy of installation.

[0013] The advantage of setting up the displacement hole is that, on the one hand, it can ensure that the lower plate is always in close contact with the bottom of the curved plate during installation, and on the other hand, by adjusting the distance of the displacement hole, it can be accurately aligned with the lower end of the fixing component, achieving the effect of synchronous and precise installation of both.

[0014] The concave surface refers to the side opposite to the convex surface of the curved plate. The concave surface facing the fixing member can also be understood as the convex surface facing away from the fixing member. In fact, the concave surface can be very small, or it can be a plane, or even another convex surface.

[0015] A further preferred technical solution is that: the displacement hole body includes a sliding plate and a connecting hole disposed on the end side of the sliding plate; the low plate is provided with a sliding groove for installing the displacement hole body.

[0016] A further preferred technical solution is that the bottom of the sliding groove is provided with a fixing layer.

[0017] A further preferred technical solution is that: the low-position plate is provided with a connecting groove for connecting the various sides of the sliding groove; the displacement hole body also includes a linkage installed in the connecting groove and whose two ends are respectively connected to the side of the sliding plate.

[0018] A further preferred technical solution is that: the connecting hole has a diameter of length A, and the sliding plate has a width of length B, then A:B = 1:2-5. For example, A:B = 1:2, 1:3, 1:4, 1:5, and other reasonable values ​​within this range.

[0019] A further preferred technical solution is that the connecting groove is provided with a stop member for blocking the linkage member.

[0020] A further preferred technical solution is that the suspended ceiling also includes:

[0021] Extension board;

[0022] An extension connector is used to connect the low-position plate and the extension plate.

[0023] A further preferred technical solution is that the lower end of the arc-shaped plate is provided with a locking groove for engaging the low-position plate.

[0024] A further preferred technical solution is that the ceiling also includes edge trimming components for connecting the extension plate and the side wall.

[0025] A ceiling installation method for installing the aforementioned ceiling includes the following steps:

[0026] S01. Install the elevated platform on the top of the building;

[0027] S02. Hang the fastener on the edge of the high-level board, align it with the reserved mounting holes, and secure it with screws;

[0028] S03. Align the upper end of the curved plate with the reserved mounting hole of the high-position plate, and use screws to pass through the reserved mounting hole to fix it to the high-position plate;

[0029] S04. Connect the side of the low plate to the lower end of the arc plate, and adjust the position of the displacement hole to align with the pre-drilled hole at the lower end of the fastener, and fix it with screws.

[0030] In summary, the present invention also has the following advantages:

[0031] First, the position adjustment of the displacement hole is limited by the sliding groove;

[0032] Second, multiple displacement holes are connected by a linkage to ensure that the multiple displacement holes can move synchronously;

[0033] Third, a stop element is also provided to limit the maximum movement distance of the displacement hole body;

[0034] Fourth, an auxiliary fixing layer is provided below the displacement hole body so that the position of the displacement hole body can be fixed after the bolt is installed into the connection hole. Attached Figure Description

Detailed Implementation

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.

[0044] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0045] Example: A prefabricated double-staggered stepped ceiling, having at least one curved external corner, including:

[0046] High-level board 1;

[0047] Low-position board 2;

[0048] The fastener 3 has its upper end for connecting to the high-position plate 1 and its lower end for connecting to the low-position plate 2;

[0049] The low-position plate 2 is provided with a displacement hole 4 for connecting the fixing member 3. The displacement hole 4 moves in a horizontal direction perpendicular to the fixing member 3 and is fixed in a relative position to the low-position plate 2 when the fixing member 3 is connected to the low-position plate 2.

[0050] The arc-shaped external corner is an arc-shaped plate 5, which is used to connect the high plate 1 and the low plate 2, and the concave surface faces the fixing member 3.

[0051] refer to Figure 1 When the curved plate 5 is installed between the high plate 1 and the low plate 2, the edges of the high plate 1 and the low plate 2 are staggered, and the installation height depends on the curvature of the curved plate 5. When the curvature of the curved plate 5 changes due to aging or transportation bumps and squeezing, the fixing member 3 cannot be properly aligned with the reserved holes on the high plate 1 and the low plate 2 at the same time. In other words, forcibly aligning it with the reserved holes on the high plate 1 and the low plate 2 will cause the fixing member 3 itself to bend, which will damage the strength of the fixing member 3 to a certain extent. In this embodiment, a displacement hole 4 is provided on the low plate 2. When the curvature of the curved plate 5 changes, the displacement hole 4 can move closer to the curved plate 5 or move away from the curved plate 5 to accommodate this change, so as to ensure that when the fixing member 3 is aligned with the reserved hole on the high plate 1, the displacement hole 4 can still be aligned with the reserved hole at the lower end of the fixing member 3.

[0052] Figure 1The image only shows the case where the concave surface of the arc-shaped plate 5 faces the fixing member 3. It can be inferred that when the convex surface of the arc-shaped plate 5 faces the fixing member 3, the displacement hole 4 still has the above-mentioned function. That is, the function of the displacement hole 4 does not depend on the shape of the arc-shaped plate 5. As long as the arc-shaped plate 5 deforms and causes a change in the horizontal distance between its two ends, the displacement hole 4 can offset the installation difficulties caused by this deformation by moving in the same direction.

[0053] The displacement hole body 4 includes a sliding plate 401 and a connecting hole 402 provided on the end side of the sliding plate 401; the low plate 2 is provided with a sliding groove 201 for installing the displacement hole body 4.

[0054] refer to Figures 3-4 The groove direction of the sliding groove 201 is perpendicular to the vertical projection of the fixing member 3, so that the sliding plate 401 can move along the groove direction of the sliding groove 201. That is to say, during the movement of the sliding plate 401, the connecting hole 402 is always on the same straight line perpendicular to the vertical projection of the fixing member 3 with the reserved hole below the fixing member 3. This ensures that when the sliding plate 401 moves, it will not cause misalignment between the connecting hole 402 and the reserved hole below the fixing member 3 in the vertical direction of the extension direction of the sliding plate 401. The above-mentioned misalignment is quite serious because it cannot be compensated for by moving the sliding plate 401.

[0055] In a preferred embodiment, the number of sliding plates 401 and sliding grooves 201 are equal.

[0056] In a preferred embodiment, four or more sliding plates 401 are provided on the lower plate 2. Figure 3 The diagram shows four sliding plates 401 set on the low plate 2.

[0057] In a preferred embodiment, the lower end of the arc-shaped plate 5 is provided with a locking groove 501 for engaging the lower plate 2. Whether the lower plate 2 and the arc-shaped plate 5 are fully installed can be determined by whether the outer end of the lower plate 2 is fully inserted into the locking groove 501.

[0058] <Regarding the fixing layer 202 set on the bottom surface of the sliding groove 201>

[0059] The bottom of the sliding groove 201 is provided with a fixing layer 202. The fixing layer 202 can be relatively soft, as it does not need to bear the vertical support force on the lower plate 2 after the fixing bolt is inserted; this support force can be directly provided by the sliding plate 401. When the fixing bolt used to fix the reserved hole and connecting hole 402 below the fixing member 3 is inserted into the fixing layer 202, it can prevent the sliding plate 401 from continuing along the sliding groove 201. The fixing layer 202 provides the fixing bolt with two functions: on the one hand, it can fix the reserved hole and connecting hole 402 below the fixing member 3, thus providing vertical support for the lower plate 2; on the other hand, by extending its lower end into the fixing layer 202, it can fix the position of the sliding plate 401.

[0060] In a preferred embodiment, the bonding layer 202 is made of either synthetic rubber or natural rubber.

[0061] In a preferred embodiment, the bonding layer 202 is made of either oak or poplar wood.

[0062] In a preferred embodiment, the bonding layer 202 uses a resin cured product, the resin including phenolic resin and epoxy resin.

[0063] <Regarding the connecting groove 203 and the linkage 403 disposed therein>

[0064] The low plate 2 is provided with a connecting groove 203 for connecting the various sides of the sliding groove 201; the displacement hole 4 also includes a linkage 403 installed in the connecting groove 203 and connected at both ends to the side of the sliding plate 401.

[0065] refer to Figure 7 The connecting groove 203 is disposed on the side of the sliding groove 201, and the entire space inside the connecting groove 203 is disposed inside the lower plate 2. It can be understood that the connecting groove 203 is a cavity in the lower plate 2, and the openings at both ends are connected to the sliding groove 201. The connecting groove 203 can be used to provide the possibility of mechanical communication between the sliding plates 401 located in two adjacent sliding grooves 201.

[0066] In this embodiment, the linkage 403 is a component for realizing the mechanical communication. Through the action of the linkage 403, when one sliding plate 401 moves, the other sliding plates 401 can move simultaneously. This scenario is mostly encountered when installing the lower plate 2. First, the connecting hole 402 on one of the sliding plates 401 is aligned with the pre-drilled hole below the fixing member 3. At this time, multiple sliding plates 401 can be moved simultaneously through the linkage 403 so that their corresponding connecting holes 402 are also aligned with the corresponding pre-drilled holes below the fixing member 3, facilitating the installation process.

[0067] Another function of the linkage 403 is that when the reserved hole below the fixing member 3 and the connecting hole 402 are fixed together by the fixing bolt, even if the fixing bolt is not further fixed into the fixing layer 202, the vertical fixing of the low plate 2 is completed. This is because the linkage 403 is inserted into the connecting groove 203, which realizes the suspension function of the low plate 2, and thus realizes the support function of the low plate 2.

[0068] In another design, the connecting groove 203 is formed vertically from the surface of the lower plate 2. In this design, the linkage 403 cannot suspend the lower plate 2. Therefore, when installing the lower plate 2, the fixing bolt must not only be fully secured to the pre-drilled hole and connecting hole 402 below the fixing member 3, but also extend further into the fixing layer 202 to complete the fixing of the lower plate 2. The advantage of this design is that the linkage 403 can be directly installed into the connecting groove 203 on the surface of the lower plate 2, and can be assembled on-site without pre-assembly in the factory, and it is replaceable.

[0069] In a preferred embodiment, two linkages 403 are provided and symmetrically arranged along the longitudinal axis of the sliding plate 401. The longitudinal axis is a straight line perpendicular to the extension direction of the sliding plate 401 and passes through the center point of the sliding plate 401. The two linkages 403 can balance the sliding plate 401.

[0070] The connecting hole 402 is provided with a thread for fastening, so that the fixing bolt can be used with a bolt with external threads. Preferably, a screw can be used to facilitate screwing the fixing member 3 in during installation.

[0071] <Width setting of slider 401>

[0072] refer to Figure 5 The longitudinal distance between each sliding groove 201 is the longitudinal length of the connecting member 403 and the connecting groove 203, which is related to the overall suspension strength of the lower plate 2. The longitudinal distance between the sliding grooves 201 is affected by the width of the sliding groove 201 itself; that is, the wider the sliding groove 201, the smaller the longitudinal length of the connecting groove 203. Therefore, theoretically, the width of the sliding groove 201 should be as small as possible to allow the connecting groove 203 to have a larger longitudinal length for the suspension and fixing process of the lower plate 2. A narrower connecting groove 203 also reduces the required width of the sliding plate 401, thereby saving material costs. However, the connecting hole 402 is set on the sliding plate 401, so the width of the sliding plate 401 is also related to the bearing strength of the lower plate 2. Therefore, the width of the sliding plate 401 should also be as large as possible.

[0073] Based on the above issues, tests were conducted on the width of the sliding plate 401 and the maximum weight that the lower plate 2 as a whole could withstand. Since the specifications of the lower plate 2 are related to actual needs, and the specifications of the connecting hole 402 are generally positively correlated with the overall specifications of the lower plate 2, we assume the connecting hole 402 has a diameter of length A, and the sliding plate 401 has a width of length B. The ratio A:B can then reflect the width of the sliding plate 401 relative to the overall lower plate 2. In the test, we set A:B = 1:x. The test results showed that when x is less than 2, the load-bearing capacity of the lower plate 2 drops sharply, indicating that the strength of the sliding plate 401 is too low to support the overall mass of the lower plate 2 and its structure. Furthermore, when x is greater than 5, the load-bearing capacity of the lower plate 2 also begins to decline, indicating that the load-bearing capacity of the linkage 403 also begins to decline.

[0074] In addition, tests revealed that when the value of x is 3, the lower plate 2 has structural load-bearing capacity.

[0075] <Regarding stop component 204>

[0076] The communicating groove 203 is provided with a stop member 204 for blocking the linkage member 403. (Reference) Figure 7 The stop member 204 is set in the connecting groove 203. When the linkage member 403 touches the stop member 204, the sliding plate 401 stops moving. The stop member 204 limits the extreme movement distance of the sliding plate 401 and can be used to judge some unqualified arc plates 5 to avoid excessive deformation of the arc plates 5. It can still be installed on the ceiling through the movable design of the displacement hole 4.

[0077] In another approach, by limiting the length of the sliding groove 201, when the sliding plate 401 reaches its limit position, the outermost sliding plate 401 just abuts against the inner side of the sliding groove 201, thus achieving the same effect as the stop member 204. In this approach, the distance between the stop member 204 and the inner side of the sliding groove 201 can be set to match the distance between the multiple linkage members 403. Thus, when the side of the sliding groove 201 abuts against the outermost linkage member 403, the stop member 204 can assist the sliding groove 201 in simultaneously abutting against the inner linkage member 403, improving the stopping capability of the linkage member 403.

[0078] Other structures that constitute a suspended ceiling

[0079] The suspended ceiling also includes:

[0080] Extension board 6;

[0081] The extension connector 7 is used to connect the low plate 2 and the extension plate 6.

[0082] When a multi-tiered suspended ceiling is required outside of the curved external corner, multiple extension plates 6 can be connected to the lower plate 2 via extension connectors 7 to achieve the purpose of setting up a multi-tiered ceiling. The specifications of the extension connectors 7 can be selected by the position of the outer end connection hole 402 after the sliding plate 401 is fixed in position.

[0083] A ceiling installation method for installing the aforementioned ceiling includes the following steps:

[0084] S01. Install the elevated platform 1 on the top of the building;

[0085] S02. Hang the fastener 3 on the edge of the high-position plate 1, align it with the reserved mounting hole, and fix it with screws;

[0086] S03. Align the upper end of the arc plate 5 with the reserved mounting hole of the high plate 1, and use screws to pass through the reserved mounting hole to fix and connect it to the high plate.

[0087] S04. Connect the side of the low plate 2 to the lower end of the arc plate 5, and adjust the position of the displacement hole 4 to align with the pre-drilled hole at the lower end of the fixing part 3, and fix it with screws.

[0088] The devices used in the above steps, as well as the fixing screws, all have standard specifications in existing technology. The aforementioned suspended ceilings are mostly used in private residences to provide a homey atmosphere through the curved external corners.
