Description

Technical Field

[0001] The invention relates to the technical field of ceiling structures, and in particular to a suspended ceiling curtain box structure and an installation method. Technical Background

[0002] Prefabricated decoration is a decoration method that combines and installs factory-produced parts on site, mainly including dry-type floor (ground), integrated kitchen, integrated bathroom, pipeline and structure separation, etc. The four major characteristics of prefabricated decoration include standardized design, industrialized production, assembly construction and information-based coordination.

[0003] In the field of suspended ceilings, prefabricated decoration is a common decoration method. For example, the Chinese utility model patent with the authorization announcement number CN212224370 U discloses an installation structure of a prefabricated stepped suspended ceiling light trough, including a suspended ceiling board, etc. The installation structure of the suspended ceiling light trough is prefabricated in the factory and can be directly assembled on site. The installation process is simple, time-saving and labor-saving, which greatly improves the construction efficiency, while improving the installation quality and reducing the construction cost.

[0004] The prefabricated decoration of the suspended ceiling is often assembled together with the curtain installation structure, that is, the curtain installation structure is a common part of the suspended ceiling structure. For example, the Chinese invention patent with application publication number CN 112450705 A discloses a hidden curtain box structure, including a curtain box top panel 2, a curtain box guide rail 3 arranged below the curtain box top panel 2, a curtain box enclosure panel 4 arranged on both sides of the curtain box guide rail, and a top panel 6 arranged at the bottom of the curtain box enclosure panel. One curtain box top panel 2 and two curtain box enclosure panels 4 form a groove with a bottom opening. The edge of the top panel 6 is vertically connected to the two ends of the bottom opening of the groove. The top of the curtain box top panel 2 is provided with a top hanging member 1 for connecting the curtain box top panel 2 and the roof 7. The curtain box enclosure panel 4 is perpendicular to the curtain box top panel 2, and the top panel 6 is parallel to the curtain box top panel 2. The installation position of the curtain box is not limited, the applicability is strong, it can be used in the middle partition of the suspended ceiling, and it has many uses. The curtain box structure is hidden in the top panel as a whole, and the shape is beautiful.

[0005] It is worth noting that: in the curtain installation structure, the curtain box top panel 2 and the curtain box closing plate 4 are fixedly connected by a connecting piece 21, that is, the connecting piece 21 is fixedly connected to the connection between the curtain box top panel 2 and the curtain box closing plate 4 by screws through two contact surfaces respectively. Whether this connection method is firm and stable depends entirely on whether the screws and the threaded connection between the curtain box top panel 2 and the curtain box closing plate 4 are firm. The firmness of the threaded connection has high requirements on the density and hardness of the plate itself, that is, this connection structure can only be used to connect plates with high physical properties, the scope of application is limited and the material cost is high, and even if high-performance plates are used, it is difficult to ensure the stability and firmness of the threaded connection structure after long-term use.

[0130] In summary, The present invention has the following beneficial effects :

[0131] 1. The curtain box structure described in the embodiment of the present application mainly adopts the form of adjacently arranged card slots to clamp the corresponding curtain box top plate and curtain box side plates. When necessary, it can also be supplemented with fixed connection on the basis of the clamping connection. When arranged in this way, the card slot is the main bearer of the curtain gravity and lateral tension. The card slot is usually made of alloy material. Unless violently operated, it will basically not be deformed due to normal use. The auxiliary fixed connection is more to prevent the relative sliding between the curtain box top plate, the curtain box side plates and their connection structure. This technical purpose does not require high strength of the fixed structure. Therefore, the connection structure is more solid than the prior art and has better stability after long-term use.

[0132] 2. The bottom of the top plate clamping groove and one of the groove walls of the side plate clamping groove share a plate, or the bottom of the side plate clamping groove and one of the groove walls of the top plate clamping groove share a plate. The purpose of this arrangement is to enable one of the plates to provide additional support to the other plate, thereby increasing the integrity of the connection structure;

[0133] When the top plate and the side plates of the curtain box are both flat plates and are arranged perpendicular to each other, one plate has a better supporting effect on the other plate;

[0134] 3. The curtain box structure is suitable for being set between the wall and the edge of the ceiling board, and is especially suitable for the ceiling structure in a small space;

[0135] 4. When using transition connectors to connect the curtain box top plate and curtain box side plates, first snap the two plates in place to facilitate subsequent fastening operations. The assembly process is completed in one go, faster and less prone to errors.

[0136] 5. Make full use of the caulking slots at the edges of the ceiling panels, and form protruding strips in the edge sealing connectors to cooperate with the caulking slots to achieve snap-in connection, which will have a better snap-in effect.

[0137] Further , the assembled small space ceiling structure has the following beneficial effects:

[0138] 1. The ceiling structure described in the embodiment of the present application is suitable for use in a small space for the following reasons:

[0139] In the suspended ceiling structure of a larger space, the length and span of the keel used are both larger. If the middle part of the keel is not reinforced by the original top fixation, the middle part of the keel is easy to deform and sag downward. Therefore, the suspended ceiling of a large space is not suitable for the assembled structure described in this application.

[0140] However, this problem does not exist in the suspended ceiling of a small space. The length and span of the keel itself are short, so it is not easy to deform. The bearing points can be set on the side walls at both ends of the keel without relying on the original top for bearing, so the floor will not be damaged. At the same time, the suspended ceiling structure can still ensure considerable stability and strength.

[0141] 2. The ceiling structure is easy to operate, requires few procedures and takes a short installation time;

[0142] 3. When the height of the ceiling installation space is sufficient, you can add a reinforcement keel above the ceiling keel. The reinforcement keel and the ceiling keel are staggered to improve the deformation resistance of the ceiling structure;

[0143] 4. When the height of the ceiling installation space is insufficient, you can also flexibly choose to install only the ceiling keel, which can also ensure a certain degree of structural stability;

[0144] 5. The fourth connection part is arranged between the two ceiling panels, which can not only enhance the stability of the connection structure between the ceiling panels, but also effectively cover the connection gap between the two ceiling panels;

[0145] 6. You can also install curtains and / or trim the ceiling surface at the corresponding position as needed, which is convenient and flexible.

[0146] Further The preferred double-base structure of the suspended ceiling has the following beneficial effects:

[0147] 1. The first connection part described in the embodiment of the present application is only fixed when the base fixing member is connected to the side wall of the base. The other connections do not require any fixing members (such as screws, bolts, etc.) to achieve the connection of the ceiling keel. The convenience brought by this is: it greatly reduces the cumbersome operation steps such as drilling and screwing, and it is more labor-saving when installing / disassembling the ceiling keel;

[0148] 2. The base fastener and keel clamping member involved in the first connection part are both simple structures, easy to form an integral part, with low production difficulty and low cost;

[0149] 3. The base fasteners and keel clamping parts involved in the first connection part are highly versatile. For most types of keels, only first connection part accessories of uniform specifications are needed for installation, without the need to produce first connection part accessories of different specifications;

[0150] High versatility is specifically reflected in:

[0151] a. The receiving platform can receive objects of various specifications / shapes, such as one end of a rod-shaped reinforcement keel or a plate-shaped first clamping plate;

[0152] b. As long as it can accommodate the specifications of the ceiling keel, the keel slot can be clamped with the end of the ceiling keel of any shape / style;

[0153] 4. Under the premise that the connection of the ceiling keel can be realized without any fasteners, the connection strength of the first connection part is guaranteed;

[0154] The receiving platform matched with the reinforcement plate has sufficient receiving strength;

[0155] The lower surface of the first clamping plate is clamped with the upper surface of the receiving platform, and the two surfaces are easily set to be rough surfaces, that is, sufficient friction can be formed between the two surfaces to prevent relative displacement between the base fixing part and the keel clamping part;

[0156] The first clamping surfaces of the two opposite keel clamping parts are clamped on the receiving platform respectively, and the corresponding two second clamping surfaces are clamped on the two ends of the ceiling keel, and the ceiling keel itself is clamped in the keel clamping groove, that is, the ceiling keel is supported by the structure of the keel clamping groove, and then the two opposite second clamping surfaces are supported by the rigidity of the ceiling keel itself, so that the connection points of various parts of the first connection part are guaranteed to be balanced and strongly supported;

[0157] 5. The distance between the upper groove wall and the groove bottom is larger than that of the lower groove wall. This technical feature is intended to make the pressure exerted by the upper groove wall on the ceiling keel form a torque. This torque makes the upper groove wall act on the ceiling keel in the following manner: one end of the ceiling keel has a rotation tendency downward and toward the side wall of the base body. This rotation tendency buckles the ceiling keel under the upper groove wall, so that the ceiling keel produces a slight deformation within the range allowed by its own material properties, and this deformation brings about reverse tension. The pair of action / reaction forces of pressure and tension prompt the ceiling keel to be more firmly clamped in the keel slot;

[0158] 6. The inner contours of the first limiting hole and the second limiting hole of the third connecting part are respectively matched with the outer contours of the reinforcement keel and the outer contours of the ceiling keel, that is, the external force acting on the ceiling keel will be transmitted to the third connecting part through the second limiting hole, and at the same time, the third connecting part will transmit the force to the reinforcement keel through the first limiting hole, so that the reinforcement keel can fully participate in the stabilization of the ceiling structure.

[0159] Further , the preferred ceiling panel structure has the following beneficial effects:

[0160] 1. The ceiling panel structure described in the embodiment of the present application adopts a second connection part with a hinged connection structure to connect the ceiling plate and the ceiling keel. During installation, it is only necessary to first fix one end of the second connection member on the upper surface of the ceiling plate, then lift the ceiling plate to the bottom of the ceiling keel, and then rotate the hinge to achieve the connection between the second connection part and the ceiling keel, which saves time and effort while maintaining firmness;

[0161] 2. The symmetrically arranged pivotal connection structure of the two sets of rotating pins and the rotating sleeve not only enhances the strength of the pivotal connection, but also makes the force on the pivotal connection more balanced, making it less likely to deform or be damaged;

[0162] 3. One end of the first connecting plate is connected to one side of the notch, rather than to the corresponding position in the middle of the groove side wall below. This connection method allows the side wall above the notch to exert downward pressure on the ceiling keel after the gravity of the ceiling plate is transmitted through the first connecting plate. The downward pressure is located at the edge of the notch, thus forming a torque. This torque causes the upper groove side wall to act on the ceiling keel in the following manner: tightly clasping the upper surface of the ceiling keel and making the bottom of the groove close to the outer surface of the ceiling keel, so that the keel limit buckle can clamp the ceiling keel more firmly.

[0163] 4. The keel limiters and ceiling panel fixing parts are all one-piece molded parts with simple structures, low manufacturing difficulty and low production cost, and are suitable for mass production.

[0164] Further , the preferred panel joint structure has the following beneficial effects:

[0165] 1. The panel joint structure described in the embodiment of the present application realizes the connection of the upper surface, the inner side and the lower surface of the ceiling panel by connecting the folded edges, the caulking strips and the ceiling panel edge banding strips, and realizes the serrated connection structure of the occlusal engagement between the ceiling panel and the caulking member with a simple structure through the cooperation with the first ceiling card block and the second ceiling card block. In addition to realizing the basic function of caulking, the serrated connection structure greatly improves the connection strength and connection stability;

[0166] 2. The caulking strip is firstly connected with the caulking groove, which plays a positioning role for the fourth connection part, and facilitates the fixing operation of the connection folding edge on the upper surface of the ceiling board. Therefore, due to the existence of the fixing structure, the connection strength and stability of the caulking are further improved;

[0167] 3. The receiving platform has an arc surface as the lower surface, and the two receiving surfaces are located on both sides of the arc surface structure, which can effectively support the ceiling board and prevent stress from concentrating on the receiving platform, thereby enhancing the supporting effect;

[0168] 4. The first caulking strip and the second caulking strip, which are hollow inside, save material costs and make the fourth connecting part lighter;

[0169] 5. The connecting fold only covers and is fixed to the upper surface of one of the ceiling panels, which facilitates the disassembly of the other ceiling panel and the fourth connecting portion, thereby simplifying the disassembly and assembly procedures of the entire ceiling.

[0170] Further The preferred ceiling trimming structure has the following beneficial effects:

[0171] 1. The edge trimming plate in the ceiling edge trimming structure described in the embodiment of the present application does not require an extra edge-wrapping structure, and has the advantage of being lightweight, and thus each of its connection nodes is not prone to loosening and deformation;

[0172] 2. The ceiling edge trimming structure does not require the ceiling board to be fixedly connected to the upper positioning member or the upper clamping member, so that the assembly process is simplified;

[0173] 3. The upper and lower clamping parts have simple structures and are easy to form in one piece. The edge plate is also only a flat plate structure. These components are easy to realize quantitative production and have low production costs.

[0174] 4. The ceiling edge trimming structure mainly uses the upper and lower clamping parts made of alloy to limit the edge trimming board and the edge trimming positioning part group, rather than the edge trimming board itself. Therefore, the connection strength of the clamping part is high and not easy to deform;

[0175] 5. In the ceiling edge trimming structure, the edge trimming plate is connected with the edge trimming positioning member group through an alloy clamping member group. When subjected to pressure or other external stress, the elasticity and deformability of the clamping member group itself can absorb and release the impact of the external force, thereby enhancing the overall stability of the edge trimming structure;

[0176] However, the elasticity, deformability and recovery ability of the materials of the edge trimming boards (such as wood, plastic wood, plywood, etc.) are generally weak. When the edge trimming board's own materials are used to cope with external stress, it is not conducive to maintaining the stability of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS
