Description

Technical Field

[0001] This invention belongs to the field of building decoration hoisting technology, and particularly relates to an embedded integrated ceiling device based on a large space box structure. Background Technology

[0002] Currently, most integrated ceiling installations on the market adopt a structure of connecting rods + main keel + secondary keel + ceiling panel. Traditional integrated ceiling installations generally require connecting rods to be connected to the floor slab to support the weight of the integrated ceiling structure. Furthermore, current traditional integrated ceiling installations are mostly installed under beams, which occupies a significant amount of the building's clear height.

[0003] In existing technologies, a box-type structure formed by hollow beams with a mezzanine is a novel and special structural form. It is generally suitable for assembly into large-span spaces. Its floor consists of upper and lower ribs, floor slabs, and shear keys. The span between the ribs is usually 2-4 meters. The upper and lower ribs of the hollow beam (i.e., hollow mezzanine floor structure) have a hollow structure, allowing electromechanical pipelines to be interspersed between the upper and lower ribs without occupying the height under the beams. The lower ribs of the box-type structure can provide load-bearing support points for the integrated ceiling structure. One of the purposes of the box-type structure invention is to reduce the overall height occupied by the ceiling by utilizing its special structure, thus maximizing the preservation of the building's net height. For example, existing technologies such as Chinese patent applications CN202310376359.8 and CN201620824156.6 disclose a hollow beam structure for prefabricated large-span spaces, which can form a large-span space by combining multiple hollow box-type structures.

[0004] Clearly, traditional integrated ceiling installation methods with hanging rods are no longer suitable for box-type structure buildings. Due to the diverse types of electromechanical systems and complex piping systems in large-span public buildings, the ceiling space contains intricate arrangements of electromechanical pipelines, especially the bulky air conditioning duct systems. Traditional integrated ceiling designs mostly utilize connecting rods for load-bearing, but the installation of these rods presents challenges such as high construction difficulty, unavoidable intersections with electromechanical pipelines, and weak connections between the rods and the floor slab. The hollow structure of a box-type structure provides space for electromechanical pipeline installation, but the space within the hollow structure is limited. If steel reinforcement is driven into the box-type structure to install connecting rods, it is impossible to avoid intersections with the complex pipeline network inside the box-type cavity, further complicating construction and installation. Furthermore, traditional integrated ceiling structures, installed under beams, occupy a significant portion of the building's ceiling height, making them unsuitable for box-type structure buildings. In addition, in large-span box structures (i.e., large-span hollow space frame structures composed of multiple box structures), there are a large number of hollow beams, resulting in a large amount of repeated installation and maintenance of integrated ceiling devices. Therefore, a more convenient, faster, and more stable integrated ceiling installation method is needed.

[0005] Therefore, in response to the problems of difficult construction of connecting rods in large-space box-shaped structures, intersection of connecting rods with electromechanical pipelines, weak connection between connecting rods and floor slabs, and inconvenience for quick and stable batch installation of integrated ceiling devices, there is an urgent need to design an embedded integrated ceiling device for large-space box-shaped structures. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] Based on this, the present invention proposes an embedded integrated ceiling device based on a large-space box structure. This integrated ceiling device avoids the technical problems of high construction difficulty, unavoidable intersection with electromechanical pipelines, and weak connection between the connecting rod and the floor slab when installing the connecting rod. It can also more conveniently, quickly and stably disassemble and assemble the integrated ceiling device in batches, without the need for heavy keel components, and has high construction safety. It is particularly suitable for use in box structures with large spans and large spaces, such as public buildings.

[0008] (II) Technical Solution

[0009] To address the aforementioned technical problems, this invention proposes an embedded integrated ceiling device based on a large-space box-type structure, comprising aluminum square tubes, wall ties, ceiling panel connectors, and ceiling panels. The ceiling panel connectors include a first type and a second type. The wall ties are connected to the lower rib beam of the box-type structure and the aluminum square tubes, respectively. Four aluminum square tubes parallel to the ground are connected end-to-end by the wall ties and arranged in a rhomboid shape. Each aluminum square tube is connected to two adjacent ceiling panels through a first type of ceiling panel connector. The ceiling panels are connected to the lower rib beam through the second type of ceiling panel connector.

[0010] Furthermore, the aluminum square tube includes two positioning grooves and a second connecting hole. The two positioning grooves, which are set downwards, are respectively located at two intersections between the edge surface of the ceiling panel and each aluminum square tube. The positioning grooves are located at the bottom of the aluminum square tube and are set at an inclined angle relative to the length direction of the aluminum square tube. The bottom central axes of the two positioning grooves are perpendicular to each other. The second connecting hole is located inside the positioning groove and is a hole that runs vertically through the tube.

[0011] The first type of ceiling panel connector includes a connecting rod, two sets of rollers, and two connecting grooves. The connecting rod is located at the top of the ceiling panel connector, and the two sets of rollers are symmetrically arranged on the left and right sides opposite the connecting rod. The two sets of rollers are located at the bottom of the ceiling panel connector, and the connecting grooves are located at the bottom of the ceiling panel connector, forming a double S-shape through the clamping of the rollers. The first type of ceiling panel connector is fixedly connected to the second connecting hole of the aluminum square tube through the connecting rod and bolts, and can be snapped together with two adjacent ceiling panels below.

[0012] Furthermore, the first type of ceiling panel connector is arranged parallel to the lower rib beam on one side, and the upper and lower sides of the positioning groove are parallel to the common side located between the two ceiling panels; in the extension direction of the lower rib beam on one side, the length of the positioning groove is greater than the length of the first type of ceiling panel connector and less than the diagonal length of the first type of ceiling panel connector, so as to limit and fix the first type of ceiling panel connector.

[0013] Furthermore, the aluminum square tube also includes a first connecting hole, which is located on both sides of the aluminum square tube and is a through hole.

[0014] Furthermore, the wall connector includes two wall lugs, two free ends, a third connecting hole, and a fourth connecting hole. The upper part of the free end located in the middle of the wall connector is open, which is used to cooperate with the first connecting hole to achieve a detachable connection. The two free ends are set at a certain angle. The two wall lugs located on both sides of the free ends are connected to the lower rib beam of the box structure. The third connecting hole is located on the two wall lugs on the left and right sides of the wall connector. The fourth connecting hole is located on the side of the two free ends of the wall connector and cooperates with the first connecting hole to form a through hole.

[0015] Furthermore, the second type of ceiling panel connector includes a connecting lug, a roller, and a connecting groove. The roller is located at the lower part of the ceiling panel connector, and the connecting groove is located at the bottom of the ceiling panel connector. It is double S-shaped by the clamping of the roller. The connecting lug is located on one side of the ceiling panel connector and is used to fix the ceiling panel connector to the lower rib beam of the box structure. The opening direction of the connecting lug and the connecting groove and the axial direction of the roller are parallel to each other.

[0016] Furthermore, the ceiling panel includes a first type of ceiling panel and a second type of ceiling panel. The first type of ceiling panel is located at the four right angles of the box-type structural unit, and each side is provided with a first connector located in the middle. The second type of ceiling panel is located at the four non-right angles around the box-type structural unit, and the second type of ceiling panel is also provided with four first connectors. No first connector is provided on the side adjacent to the air conditioning vent. Two first connectors are located on the side of the second type of ceiling panel that is fixed to the lower rib beam. A first connector is provided in the middle of the left and right sides of the side adjacent to the air conditioning vent.

[0017] Furthermore, the first connector is located above the perimeter of the ceiling panel, is heart-shaped and parallel to the edge of the ceiling panel, for snap-fit ​​connection with the connecting groove above.

[0018] Furthermore, each box-type structural unit is equipped with four aluminum square tubes and eight ceiling panels. The four aluminum square tubes arranged in a diamond shape are parallel to the eight ceiling panels below. The wall ties, aluminum square tubes and ceiling panel connectors are all set on the same plane at the upper and lower edges of the lower rib beam.

[0019] Furthermore, the installation sequence of the embedded integrated ceiling device based on the large-space box structure is as follows: install the electromechanical pipeline system → connect the wall tie to the lower rib beam of the box structure → connect the aluminum square tube to the wall tie → connect the first type of ceiling panel connector to the aluminum square tube → connect the second type of ceiling panel connector to the lower rib beam of the box structure → install the air conditioning vents → install the sprinkler heads, smoke detectors and other reserved hole components → engage the ceiling panel with the upper ceiling panel connector → complete the integrated ceiling installation.

[0020] (III) Beneficial Effects

[0021] Compared with existing technologies, the main advantages of the embedded integrated ceiling device based on a large-space box structure of the present invention include:

[0022] (1) The present invention provides an embedded integrated ceiling device based on a large space box structure, which can make full use of the special hollow sandwich structure in the box structure, so that the lower rib beam of each box structure can provide a force support point for the integrated ceiling structure. There is no need to use connecting rods for load bearing. A diamond-shaped aluminum square tube structure can be used instead of connecting rods for load bearing, avoiding the problems of high construction difficulty, unavoidable intersection with electromechanical pipelines, and weak connection between connecting rods and floor slabs that exist when installing connecting rods.

[0023] (2) The embedded integrated ceiling device based on a large-space box structure provided by this invention only requires placing the aluminum square tube with positioning groove, the wall tie, and all the second type of ceiling panel connectors installed on the lower rib beam of the box structure at the same water level, and fixing the first type of ceiling panel connector in the downward-facing positioning groove to freely engage and install the ceiling panels around the perimeter. This facilitates rapid and batch ceiling installation and removal. Its overall structure is simple and can provide stable support for the eight ceiling panels around the perimeter except for the central air conditioning vent. Furthermore, due to the light weight of each component and the absence of heavy keel components, its construction safety is also high. In addition, by placing the wall tie, aluminum square tube, and ceiling panel connector on the same plane at the lower edge of the lower rib beam of the box structure, the integrated ceiling structure can be completely embedded inside the box structure. Compared with traditional integrated ceilings, the integrated ceiling form of this invention can greatly reduce the building height occupied by the integrated ceiling, increase the usable net height of public buildings, and achieve a beautiful and neat visual effect.

[0024] (3) The aluminum single-panel ceiling panel and the ceiling panel connector in this invention are connected by a double S-shaped smooth curve buckle connection, which makes the installation and disassembly of the ceiling panel more convenient and facilitates the maintenance or replacement of the ceiling panel in the future.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described below.

[0039] Please refer to this carefully. Figure 1 This invention discloses an embedded integrated ceiling device based on a large-space box-type structure, including aluminum square tubes 1, wall ties 2, ceiling panel connectors 3, and ceiling panels 4. The ceiling panel connectors 3 include a first type and a second type. The wall ties 2 are connected to the lower rib beam 6 of the box-type structure and the aluminum square tubes 1, respectively. The four aluminum square tubes are arranged in a diamond shape after being connected by the wall ties. The aluminum square tubes 1 can also be connected to two adjacent ceiling panels 4 via a first type of ceiling panel connector. The ceiling panels 4 can also be connected to the lower rib beam 6 of the box-type structure via a second type of ceiling panel connector. This invention aims to eliminate the need for connecting hangers, utilizing the unique nine-square grid ceiling structure of the box-type structure, and using four aluminum square tubes instead of connecting hangers for load-bearing, avoiding problems such as high construction difficulty, unavoidable intersections with electromechanical pipelines, and unstable connections between connecting hangers and the floor slab.

[0040] See Figure 2-9 As shown, the present invention Figure 1 The specific structure and usage of the aluminum square tubes, wall ties, ceiling panel connectors, and ceiling panels used are as follows:

[0041] (1) Aluminum square tube:

[0042] See Figure 2 As shown, the aluminum square tube 1 is a square thickened aluminum square tube, which is used to support the weight of the integrated ceiling structure. The four aluminum square tubes in each box structure are arranged in a diamond shape. Each aluminum square tube 1 includes a first connecting hole 11, a positioning groove 12 and a second connecting hole 13.

[0043] The first connecting hole 11 is located on both sides of the aluminum square tube 1 and is a through hole.

[0044] Two positioning grooves 12 are located at the bottom of the aluminum square tube 1, facing downwards during installation. Each positioning groove 12 is inclined at an angle relative to the longitudinal direction (i.e., along the length) of the aluminum square tube. The central axes of the bottom of the two positioning grooves 12 are perpendicular to each other. For a square arrangement of four aluminum square tubes (i.e., the box structure has a square opening), the inclination angle of the two positioning grooves 12 relative to the longitudinal direction of the aluminum square tube is preferably 45 degrees. The positioning grooves 12 are positioned at the two intersections between the edge of the ceiling panel 4 and the aluminum square tube 1. Because the ceiling panel 4 at the four right angles of the box structure intersects with the aluminum square tube 1 above at two points, each aluminum square tube 1 has two downward-facing positioning grooves 12. Each positioning groove 12 is connected to the two closest first connectors 41 on two adjacent ceiling panels through a first type of ceiling panel connector, thereby connecting and fixing two adjacent panels simultaneously through a single ceiling panel connector.

[0045] The second connecting hole 13, located within the positioning groove 12, is a through hole extending vertically, used to fix the lower type of ceiling panel connector by bolts.

[0046] (2) Wall ties:

[0047] See Figure 3 As shown, the wall tie 2 includes two wall lugs 21, two free ends 22, a third connecting hole 23, and a fourth connecting hole 24. The free end 22 located in the middle of the wall tie 2 has an open upper part, used to mate with the first connecting hole 11 on the aluminum square tube 1 for a detachable connection. The two free ends 22 are set at a certain angle. Furthermore, the wall lugs 21 located on both sides of the free ends 22 connect to the lower rib beam 6 of the box structure. Specifically, expansion bolts are inserted into the third connecting hole 23 on the wall lugs 21 to achieve a fixed connection. The two free ends 22 are respectively connected to the aluminum square tube 1. Specifically, the fourth connecting holes 24 on both sides of each free end of the wall tie 2 are respectively aligned with the first connecting hole 11 on the aluminum square tube 1, and ordinary screws and bolts are inserted to achieve the connection.

[0048] The third connecting hole 23 is located on the two wall-connecting ears 21 on the left and right sides of the wall-connecting member 2, for fixed connection with the lower rib beam 6 of the box structure. The fourth connecting hole 24 is located on the sides of the two free ends 22 of the wall-connecting member 2, and is arranged to pass through from left to right, and can cooperate with the first connecting hole 11 to form a through hole.

[0049] (3) Ceiling panel connectors

[0050] The ceiling panel connector 3 includes two types of ceiling panel connectors. The first type of ceiling panel connector is a ceiling panel connector 3 with a connecting rod 31, which is used to connect with the upper ceiling panel 4 and the aluminum square tube 1. The second type of ceiling panel connector is a ceiling panel connector 3 with a connecting ear 32 (excluding the connecting rod), which is used to realize the direct connection between the ceiling panel 4 and the lower rib beam of the box structure.

[0051] See Figure 4-5 As shown, the ceiling panel connector 3 includes a connecting rod 31, a connecting lug 32, a roller 33, and a connecting groove 34. For details, please refer to [link / reference needed]. Figure 4 It can be seen that the first type of ceiling panel connector includes a connecting rod 31, a roller 33, and a connecting groove 34, and the first type of ceiling panel connector has two sets of rollers 33 and connecting grooves 34; see also Figure 5 It can be seen that the second type of ceiling panel connector includes a connecting lug 32, a roller 33 and a connecting groove 34, and it has only one set of roller 33 and connecting groove 34.

[0052] Connecting rod 31, located at the top of ceiling panel connector 3, is inserted into the second connecting hole 13 on the aluminum square tube 1 during ceiling installation. The nut is then tightened to complete the connection. See [link to documentation] for details. Figure 8 .

[0053] The connecting ear 32 is located on one side of the ceiling panel connector 3 and is used to fix the ceiling panel connector to the lower rib beam of the box structure. The direction of the connecting ear 32 and the groove of the connecting groove 34 and the axis of the roller 33 are parallel to each other, so as to install the ceiling panel 4 at a non-right angle through the lower rib beam 6.

[0054] Rollers 33 are located at the lower part of the ceiling panel connector 3. Each set of rollers is fixed on both sides of the connecting groove 34. Their function is to facilitate the manual installation and removal of the ceiling panel. The material is generally resin that can support deformation recovery. For the first type of ceiling panel connector, two sets of rollers 33 can be symmetrically arranged on the left and right sides below the connecting rod 31 to form two connecting grooves 34, thereby connecting two adjacent ceiling panels 4.

[0055] The connecting groove 34 is located at the bottom of the ceiling panel connector 3. It is double S-shaped by the clamping of the roller 33 and can be matched and engaged with the first connector 41 on the ceiling panel 4.

[0056] (4) Ceiling panel

[0057] Ceiling panel 4 includes two types of ceiling panels:

[0058] See Figure 6 The left figure (a) and Figure 8-9As shown, the first type of ceiling panel is located at the four right angles of the box-type structural unit. The first type of ceiling panel has four first connectors 41 located at the middle of the four sides of the ceiling panel. Among them, the two first connectors 41 on the two right-angled sides of the air conditioning vent 5 near the center of each box structure are connected to the two first type of ceiling panel connectors on the aluminum square tube 1, and the other two sides are directly connected to the second type of ceiling panel connectors on the lower rib beam 6 of the box structure.

[0059] See Figure 6 The right figure (b) and Figure 7 As shown, the second type of ceiling panel is located at the four non-right angles around the box-type structural unit (i.e., around the air conditioning vent 5). The second type of ceiling panel also has four first connectors 41. No first connector is provided on the side adjacent to the air conditioning vent. Two first connectors 41 are located on the side where the second type of ceiling panel is fixed to the lower rib beam 6. A first connector 41 is provided in the middle of the left and right sides of the side adjacent to the air conditioning vent 5. Thus, it is connected to the aluminum square tube 1 through the first type of ceiling panel connector, and at the same time, it is connected to the first type of ceiling panel.

[0060] The first connector 41 is located above the perimeter of the ceiling panel 4, and is heart-shaped and parallel to the edge of the ceiling panel. The first connector 41 is welded to the ceiling panel and engages with the connecting groove 34 on the ceiling panel connector 3. When installing the integrated ceiling, the first connector 41 is inserted from bottom to top into the connecting groove 34 formed by the roller 33 on the ceiling panel connector 3 to complete the installation of the ceiling panel.

[0061] like Figure 7-9 As shown, during the installation of the integrated ceiling, the wall tie 2 is connected to the lower rib beam 6 of the box structure and the aluminum square tube 1 respectively. The aluminum square tube 1 is connected to the first type of ceiling panel connector 3. The second type of ceiling panel connector 3 is fixed on the lower rib beam 6 of the box structure. The ceiling panel 4 is connected to both types of ceiling panel connectors 3 respectively. According to the layout of the electromechanical terminals on the construction drawings: a position is reserved for the self-fixing air conditioning vent 5 in the middle (i.e., there is no ceiling panel at the air conditioning vent 5 in the center, which can be fixed by itself). The lighting fixtures are integrated with the ceiling panels. The sprinkler heads, smoke detectors and other terminals have reserved holes in the corresponding ceiling panels.

[0062] See Figure 7 As shown, the wall tie lugs of the wall tie 2 are connected to the lower rib beam 6 of the box structure via expansion bolts. Specifically, the expansion bolts are inserted into the third connecting hole 23 and driven into the lower rib beam of the box structure to complete the connection. Additionally, the free end 22 of the wall tie 2 is connected to the aluminum square tube 1. Specifically, the fourth connecting hole 24 of the free end 22 of the wall tie 2 is aligned with the first connecting hole 11 at the end of the aluminum square tube, a standard bolt is inserted, and the nut is tightened to complete the connection.

[0063] like Figure 1 and Figure 8-9 As shown, each box-type structural unit is equipped with four aluminum square tubes arranged in a diamond shape. A positioning groove is provided at the intersection of the aluminum square tube 1 and the ceiling panel for connecting the aluminum square tube to the ceiling panel connector. Specifically, the connecting rod 31 of the first type of ceiling panel connector 3 is inserted from bottom to top into the second connecting hole 13 at the bottom of the aluminum square tube. Simultaneously, the head of the first type of ceiling panel connector 3 is inserted into the positioning groove at the bottom of the aluminum square tube, and the nut is tightened to complete the connection. Because the positioning groove can accommodate the ceiling panel connector, the diamond-shaped surface formed by the aluminum square tube 1 and the wall tie 2 is parallel to the ceiling panel below. At this time, the aluminum square tube 1, the wall tie 2, and the two types of ceiling panel connectors 3 can all be placed on the same horizontal plane, facilitating rapid installation without the need to calibrate the height of each component, thus avoiding unnecessary subsequent height adjustments.

[0064] In addition, it should be pointed out that, although Figure 8 The aluminum square tube 1 and the first type of ceiling panel connector 3 shown are set on the same plane, but as Figure 9 As shown, in order to enable the first type of ceiling panel connector 3 to simultaneously... Figure 9 The two first connectors 41 within the upper and lower connecting grooves 34 are respectively engaged and fixed. The aluminum square tube 1 and the first type of ceiling panel connector 3 are set at a certain angle, and the ceiling panel connector 3 is set parallel to the lower rib beam on the right side to facilitate quick alignment and installation. For Figure 1 Regarding point B in the text, Figure 8-9 The ceiling panels a and b shown are respectively the ceiling panels at right angles and the ceiling panels at non-right angles. Furthermore, because the positioning grooves 12 are set at an angle relative to the length direction of the aluminum square tube 1, and the extensions of the angles of the two positioning grooves 12 of each aluminum square tube 1 are perpendicular to each other, it ensures that the upper and lower edges of each positioning groove 12 are aligned with the common edge of the middle ceiling panels a and b (i.e.,...). Figure 8 The connection points of the two ceiling panels are parallel, allowing the first type of ceiling panel connector 3 to be placed vertically from bottom to top into the positioning groove 12 using bolts and connecting rods 31. See also... Figure 9 As shown, in the extension direction of the lower rib beam 6 on the right side, the length of the positioning groove 12 is slightly greater than the length of the first type of ceiling panel connector 3 (i.e., the length of the rectangle) and less than the diagonal length of the first type of ceiling panel connector 3 (i.e., the length of the diagonal of the rectangle). This allows the positioning groove to limit and fix the first type of ceiling panel connector 3, preventing the first type of ceiling panel connector 3 from being driven by the ceiling panel 4 below during ceiling panel installation, thus avoiding unnecessary rotation within the positioning groove 12 (the direction of rotation can be found in the image). Figure 9 (The arrow in the image).

[0065] For the connection between the ceiling panel connector 3 and the ceiling panel 4, the first connector 41 on the ceiling panel is inserted into the connecting groove at the bottom of the ceiling panel connector 3 from bottom to top. Because the ceiling panel connector 3 is equipped with a symmetrical roller structure for the first connector 41 to be elastically engaged, the ceiling panel can be quickly installed and disassembled, which is convenient for the later maintenance and replacement of the ceiling panel.

[0066] In addition, the ceiling panels are made of aluminum single panels, and the specifications of the ceiling panels are prefabricated in the factory according to the specific project requirements to facilitate the installation of integrated ceilings with box-like structures in batches. Since roller structures are set on the ceiling panel connectors, the installation and disassembly of the ceiling panels are convenient, which facilitates the future maintenance or replacement of the ceiling panels. The integrated ceiling design of this invention can also integrate the layout and installation of electromechanical terminal equipment (such as air conditioning vents, lighting fixtures, sprinklers, smoke detectors, etc.). According to the integrated ceiling design, the cavity of each box-type structural unit is divided into nine separate small spaces. The middle space is used to place an air conditioning vent 5 that can be independently fixed by components such as ventilation ducts (i.e., the air conditioning vent does not rely on the eight ceiling panels around it for fixing; it can be fixed by the cover plate above the upper rib beam or by ventilation ducts). The two spaces on both sides of the air conditioning vent can be used to place ceiling panels that integrate ceiling and lighting fixtures. The remaining spaces are used to place ceiling panels without lighting fixtures. The ceiling panels are installed using a connection groove buckle fixing method. In addition, in this invention, it is preferred that the ceiling panels be installed flush with the bottom of the lower rib beam of the box structure to ensure the flatness and aesthetics of the space below.

[0067] The installation process of the embedded integrated ceiling device based on a large-space box structure in this invention is described in detail below:

[0068] Install the electromechanical pipeline system → connect the wall ties to the lower rib beam of the box structure → connect the aluminum square tube to the wall ties → connect the first type of ceiling panel connector to the aluminum square tube → connect the second type of ceiling panel connector to the lower rib beam of the box structure → install the air conditioning vents → install the pre-reserved hole components such as sprinklers and smoke detectors → connect the ceiling panel to the two types of ceiling panel connectors above → complete the integrated ceiling installation.

[0069] Compared with the prior art, the present invention has the following key improvements and effects:

[0070] 1. The integrated ceiling solution provided by this invention eliminates the need for connecting hangers, thus solving problems such as the difficulty of constructing connecting hangers, the intersection of connecting hangers with electromechanical pipelines, and the unstable connection between connecting hangers and floor slabs.

[0071] 2. The integrated ceiling solution provided by this invention can greatly reduce the building height occupied by the integrated ceiling structure and increase the usable net height of the building.

[0072] 3. The integrated ceiling solution provided by this invention can realize the batch and rapid installation and removal of ceiling panels in multiple box-type structures of hollow beams, which facilitates the future maintenance or replacement of ceiling panels.

[0073] 4. The integrated ceiling solution provided by this invention can integrate and deploy electromechanical terminal equipment according to the actual application scenario of the ceiling, realize the prefabricated installation of electromechanical equipment, improve the installation speed of electromechanical terminals, and achieve a beautiful and neat visual effect.

[0074] In addition, the present invention provides an embedded integrated ceiling device based on a large space box structure and its installation form. However, this form and device can be arranged in other ways according to specific circumstances, or combined with specific ceiling forms.

[0075] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly.
