Description

Technical Field

[0001] The utility model relates to the technical field of ceilings, in particular to a ceiling conversion layer structure. Background Art

[0002] Suspended ceilings are the decorative layer of a building's roof. They not only beautify interior spaces but also provide a variety of practical functions, such as thermal insulation, sound insulation, and sound absorption. They also conceal electrical, ventilation, air conditioning, communications, and fire alarm systems, facilitating their installation and maintenance.

[0003] In the production of electronic components, for some cleanrooms that require higher cleanliness levels or carry out complex process steps, the upper mezzanine height (i.e., the height between the building roof and the ceiling) is usually designed to be greater than 4 meters during planning and design to meet the needs of process pipeline layout and regular maintenance. The traditional ceiling installation method is to directly connect the ceiling to the hanging points from the building roof. However, when the upper mezzanine height exceeds 4 meters, the length of a single hanging rod will exceed 4 meters, causing the fixed ceiling to shake significantly when personnel enter the upper mezzanine for inspection and maintenance. This shaking not only wears out the stable structure of the ceiling and affects its flatness, but also causes the pipelines passing through the ceiling blind plate to loosen and fall off at the joints with the blind plate, creating gaps, which in turn affects the overall airtightness of the clean production floor. Therefore, for cleanrooms with an upper mezzanine height greater than 4 meters, a transition layer structure is often required to reduce the shaking of the suspended ceiling and ensure its stability and airtightness.

[0004] The transfer layer structure, typically designed as an intermediate layer between the building's roof and ceiling, connects the two and provides space for piping, cables, ventilation systems, and other infrastructure. Conventional technology typically uses C-shaped steel as the primary support and load-bearing component of the transfer layer. Threaded hangers are then threaded through pre-recorded slots in the C-shaped steel and secured with nuts to ensure a secure installation of the transfer layer structure. The above-mentioned transition layer structure assembled with C-shaped steel and threaded hangers has the following problems: (1) When the load on the ceiling keel is high, the structure around the hole groove of the C-shaped steel stress point is prone to deformation and bending. In severe cases, it may cause the hanger and nut at the fixed point to fall off, affecting the normal fastening effect; (2) The hanging point position of the threaded hanger is limited by the position of the hole groove of the C-shaped steel, and the hanging point position cannot be adjusted or increased according to actual needs, and the installation and use flexibility is poor; (3) The C-shaped steel is an open structure, generally provided with grooves for increasing the stability and strength of the structure and holes for installing hangers and other fixings. Such grooves and holes are extremely easy to accumulate dust and dirt, and are difficult to clean, which is not conducive to daily cleaning and maintenance in clean workshops. Utility Model Content

[0005] The utility model provides a ceiling conversion layer structure that can realize the fixed assembly of the ceiling, and is stable and reliable, flexible, and easy to clean and maintain. The specific technical solution is as follows:

[0006] A ceiling transfer layer structure is used to achieve fixed assembly of the ceiling, comprising horizontal rods and connecting components with a closed, axisymmetric, regular cross-section.

[0007] The horizontal rod is fixedly arranged below the building roof through the connecting components at its left and right ends, and is parallel to the building roof; the ceiling is fixedly arranged below the horizontal rod through the connecting components in the middle of the horizontal rod, and is parallel to the horizontal rod;

[0008] The connecting assembly includes a hoop structure and a suspension rod. The hoop structure is adapted to the horizontal rod and is sleeved on the horizontal rod. One end of the suspension rod is fixedly connected to the hoop structure, and the other end is fixedly connected to the ceiling or the building top plate.

[0009] Furthermore, the number of connection components located in the middle of the horizontal rod and used to connect with the ceiling is two or more.

[0010] Furthermore, the horizontal rod is an internal hollow structure.

[0011] Furthermore, the hollow openings at both ends of the horizontal rod are provided with sealing structures.

[0012] Furthermore, the hoop structure includes a hoop ring adapted to the horizontal rod, and a flat cover plate arranged at the opening of the hoop ring and fixedly connected to the hoop ring, and the suspension rod is fixedly connected to the hoop structure through the flat cover plate.

[0013] Furthermore, the horizontal rod is a square steel, and the clamp ring is a U-shaped bent part adapted to the square steel.

[0014] Furthermore, the suspension rod is a threaded suspension rod.

[0015] A ceiling transfer layer structure is used to achieve fixed assembly of the ceiling, comprising horizontal rods with a closed, axisymmetric regular cross section, connecting components and a supporting structure;

[0016] There are two supporting structures, which are fixedly installed on the lateral mounting surface of the building, and the supporting structures are provided with a flat support plate adapted to the horizontal rod; the left and right ends of the horizontal rod are fixedly connected to the flat support plate, so that the horizontal rod is fixedly installed below the roof of the building and is parallel to the roof of the building; the ceiling is fixedly installed below the horizontal rod through the connecting assembly in the middle of the horizontal rod and is parallel to the horizontal rod;

[0017] The connecting assembly includes a hoop structure and a suspension rod. The hoop structure is adapted to the horizontal rod and is sleeved on the horizontal rod. One end of the suspension rod is fixedly connected to the hoop structure, and the other end is fixedly connected to the ceiling.

[0018] Furthermore, the support structure is a corbel structure that can be fixed on a lateral mounting surface and provides a horizontal support surface.

[0019] Furthermore, the corbel structure is fixed to the lateral mounting surface by chemical anchor bolts.

[0020] The ceiling transition layer structure provided by the present invention can fix the ceiling below the building roof and be parallel to the building roof through the cooperation of the horizontal rod with a closed axisymmetric regular shape in cross section, the hoop structure and the hanger. Compared with the transition layer structure in the prior art that uses C-shaped steel and threaded hangers for assembly, it has the following beneficial effects: (1) The horizontal rod and the hoop structure are used for hanging point fixation, which increases the force-bearing area of ​​the hanger. The force condition is better than the single-point force of the C-shaped steel, which can better complete the hanging point fixation and is more stable and reliable.

(3) The surface of the horizontal rod structure is flat and there are no grooves or holes inside, which is conducive to daily cleaning and maintenance in the clean room.

[0021] Furthermore, for special building situations where the building roof is a non-load-bearing structure, the fixed assembly of the horizontal rod can be achieved by fixing a support structure on the lateral mounting surface of the building, so that the horizontal rod is fixedly set below the building roof and parallel to the building roof, and then the ceiling is fixedly installed below the horizontal rod through a hoop structure and a hanger, so that the ceiling can be fixedly installed below the building roof and parallel to the building roof, which has strong applicability, stability and reliability.

[0028] The utility model provides a kind of suspended ceiling conversion layer structure, can realize the fixed assembly of suspended ceiling 1, so that the suspended ceiling 1 is fixedly installed below building top plate 2, and is parallel with building top plate 2.

[0029] First embodiment

[0030] As Figure 1As shown, the ceiling conversion layer structure of the embodiment comprises horizontal rods 3 and connecting assemblies 4 arranged horizontally. Specifically, the horizontal rods 3 have a closed axial symmetric regular pattern (including square, circle, equilateral triangle, isosceles trapezoid, regular pentagon, regular hexagon and the like, which can be balanced in force), and each end of the horizontal rods 3 is provided with a set of connecting assemblies 4. The horizontal rods 3 are fixedly connected with the building roof 2 through the connecting assemblies 4 at both ends, so that the horizontal rods 3 are fixedly arranged below the building roof 2 and parallel to the building roof 2. In addition, the middle part of the horizontal rods 3 is also provided with at least one set of connecting assemblies 4. The ceiling 1 is fixedly connected with the horizontal rods 3 through the connecting assemblies 4 in the middle part of the horizontal rods 3, so that the ceiling 1 is fixedly arranged below the horizontal rods 3 and parallel to the horizontal rods 3. Thus, the ceiling 1 can be fixedly installed below the building roof 2 and parallel to the building roof 2.

[0031] As shown in the drawings, Figure 2 The connecting assembly 4 comprises a hoop structure 41 and a suspender 42. The hoop structure 41 is adapted to the horizontal rods 3 and can be sleeved on the horizontal rods 3. One end of the suspender 42 is fixedly connected with the hoop structure 41, and the other end is fixedly connected with the ceiling 1 or the building roof 2. Specifically, one end of the suspender 42 of the connecting assembly 4 at both ends of the horizontal rods 3 is fixedly connected with the hoop structure 41, and the other end is fixedly connected with the building roof 2. One end of the suspender 42 of the connecting assembly 4 in the middle part of the horizontal rods 3 is fixedly connected with the hoop structure 41, and the other end is fixedly connected with the ceiling 1.

[0032] The ceiling conversion layer structure has the following beneficial effects compared with the conversion layer structure of the prior art which is assembled by C-shaped steel and wire mouth suspender: (1) The horizontal rods 3 and the hoop structure 41 are used to fix the lifting point, which increases the stress area of the suspender 42 and is better than the single-point stress of the C-shaped steel, so that the lifting point can be fixed better and more stably and reliably; (2) The position of the lifting point of the horizontal rods 3 can be adjusted and increased according to actual needs, which is more flexible and better than the C-shaped steel and has stronger adaptability; (3) The structure surface of the horizontal rods 3 is flat and has no recess or hole, which is beneficial to the daily cleaning and maintenance in the clean room.

[0033] In some embodiments, the number of connecting components 4 located in the middle of the horizontal rod 3 and used to connect to the ceiling 1 is two or more groups; specifically, it can be two groups, three groups, four groups or even more, which should be determined according to actual assembly needs and is not limited here.

[0034] By adopting the ceiling conversion layer structure of the above structure, a connecting component 4 is added in the middle of the horizontal rod 3 to increase the hanging point position, which can make the assembly of the ceiling 1 more stable and reliable; for example, when some clean workshops need to meet production needs, the ceiling 1 in some areas requires better load-bearing performance, such as some areas equipped with overhead crane transportation and load-bearing shelves, it is necessary to add additional hangers 42 to reinforce the keel for the load-bearing of the ceiling 1 to avoid deformation, collapse and other accidents during actual application. Therefore, adding a connecting component 4 in the middle of the horizontal rod 3 to increase the hanging point position can complete the keel reinforcement, making the assembly of the ceiling 1 more stable and reliable.

[0035] In some embodiments, the horizontal rod 3 is an internal hollow structure; the horizontal rod 3 made of solid material has a large weight itself, and it is difficult to reliably fix it to the building roof 2 if only two hangers 42 are used, and the cost of the overall transfer layer structure will rise sharply; while the horizontal rod 3 with an internal hollow structure, in addition to meeting the support and load-bearing requirements of the transfer layer structure, is lower in cost and more stable and reliable.

[0036] In some embodiments, when the horizontal rod 3 is an internal hollow structure, sealing structures 5 are provided at the hollow openings at both ends of the horizontal rod 3 .

[0037] The ceiling conversion layer structure adopts the above structure, and sealing structures 5 are provided at the hollow openings at both ends of the horizontal rod 3, so that no dust particles can enter or exit the hollow area of ​​the horizontal rod 3, effectively avoiding dust accumulation and making cleaning and maintenance easier.

[0038] In some embodiments, the sealing structure 5 includes galvanized iron sheets adapted to the hollow openings at both ends of the horizontal rod 3, and sealant that can fix the galvanized iron sheets on the hollow openings of the horizontal rod 3; of course, it can also be other common sealing structures such as sealing plugs, which are not limited here.

[0039] The ceiling conversion layer structure adopts the above structure. The galvanized iron sheet is light in weight and not easy to rust. It is fixed to the hollow opening of the horizontal rod 3 by sealant, which not only has a good sealing effect, but also has strong durability and lower cost.

[0040] In some embodiments, the hoop structure 41 includes a hoop ring 411 and a flat cover plate 412. The hoop ring 411 is adapted to the horizontal rod 3 and can wrap and support the horizontal rod 3. The flat cover plate 412 is arranged at the opening of the hoop ring 411 and is fixedly connected to the hoop ring 411. The suspension rod 42 is fixedly connected to the hoop structure 41 through the flat cover plate 412. More preferably, the hoop structure 41 is made of stainless steel.

[0041] The ceiling transition layer structure adopts the above structure. Through the mutual cooperation between the clamp ring 411 and the flat cover plate 412, the assembly is firm, more stable and reliable, and the reliability of the ceiling transition layer structure can be further improved; the clamp structure 41 is made of stainless steel material, which has high strength, is not easy to rust, has strong durability, and is more stable and reliable.

[0042] In some embodiments, as shown in this embodiment, the horizontal rod 3 with a closed mirror-symmetrical regular cross-section is square steel, and the clamp ring 411 is a U-shaped bent part adapted to the square steel, which can wrap and support the square steel from three sides; of course, the horizontal rod 3 with a closed mirror-symmetrical regular cross-section can also be round steel, etc.

[0043] The ceiling transfer layer structure using the above structure has a more uniform stress on the square steel, a more stable structure, and is easier to produce and process. When used in conjunction with the U-shaped bending piece, the ceiling transfer layer structure is more stable and reliable.

[0044] In some embodiments, the hanger 42 is a threaded hanger, the top and / or bottom of which are threaded and can be fixed to the building roof 2 or ceiling 1 by nuts or other fasteners. It is easy to install, convenient to adjust, highly adaptable, and can withstand large vertical and lateral loads, and is stable and reliable.

[0045] Second embodiment

[0046] In actual production, the building roof 2 of some clean workshops is an iron roof panel plus an insulation layer, a waterproof layer and a concrete layer, which is a non-load-bearing structure. It is impossible to bolt the hanger 42 on the building roof 2, and drilling will damage the waterproof layer, causing water leakage in the clean workshop. Therefore, the horizontal rod 3 cannot be fixedly assembled under the building roof 2 through the hanger 42. At this time, another fixed connection method is required to achieve the fixed assembly of the horizontal rod 3.

[0047] like Figure 3As shown, the ceiling conversion layer structure described in this embodiment includes a horizontal rod 3, a connecting component 4 and a supporting structure 6 with a closed mirror-symmetrical regular pattern in cross section; specifically, the number of the supporting structures 6 is two, which are fixedly arranged on the lateral mounting surface 7 of the building, and the lateral mounting surface 7 can be the side of the building structure such as a beam or a column, which is not limited here; the supporting structure 6 is provided with a flat support plate 61 adapted to the horizontal rod 3, and the left and right ends of the horizontal rod 3 are respectively placed on the flat support plate 61, and are fixed to the horizontal rod 3 through a similar fastening structure such as a hoop structure 41. The planar support plate 61 is fixedly connected, so that the horizontal rod 3 can be fixedly arranged below the building top plate 2 and parallel to the building top plate 2; the ceiling 1 is fixedly arranged below the horizontal rod 3 through the connecting component 4 in the middle of the horizontal rod 3 and parallel to the horizontal rod 3; the connecting component 4 includes a hoop structure 41 and a suspension rod 42, the hoop structure 41 is adapted to the horizontal rod 3 and can be sleeved on the horizontal rod 3; one end of the suspension rod 42 is fixedly connected to the hoop structure 41, and the other end is fixedly connected to the ceiling 1.

[0048] The ceiling transfer layer structure adopting the above structure can fix the ceiling 1 below the building top plate 2 and be parallel to the building top plate 2 by cooperating with the horizontal rod 3, the hoop structure 41, the hanger 42 and the support structure 6, which have a closed cross-section and a mirror-symmetrical regular pattern. Compared with the transfer layer structure assembled with C-shaped steel and threaded hangers in the prior art, it has the following advantages:

[0049] (1) The horizontal rod 3 and the hoop structure 41 are used to fix the hanging point, which increases the force-bearing area of ​​the hanging rod 42. The force condition is better than the single-point force of the C-shaped steel, which can better complete the hanging point fixation and is more stable and reliable; (2) The hanging point position of the horizontal rod 3 can be adjusted and increased according to actual needs. Compared with the C-shaped steel, it is more flexible and has stronger adaptability; (3) The surface of the horizontal rod 3 structure is flat, and there are no grooves or holes inside, which is conducive to daily cleaning and maintenance in the clean room; (4) It can be applied to special construction situations where the building roof 2 is a non-load-bearing structure, and it is stable and reliable.

[0050] In some embodiments, the support structure 6 is a corbel structure that can be fixed on the lateral mounting surface 7 and provide a horizontal support surface.

[0051] The ceiling transfer layer structure adopts the above structure, and adopts a corbel structure to provide a horizontal support surface fixedly connected to the horizontal rod 3. It is easy to install, has strong adaptability, is easy to maintain, and is stable and reliable, with a longer service life.

[0052] In some embodiments, as Figure 4As shown, the corbel structure is fixed to the lateral mounting surface 7 by chemical anchor bolts 8 .

[0053] The above-mentioned ceiling conversion layer structure adopts the chemical anchor bolt 8, which is a connecting part used to firmly anchor the fixing part in the substrate. It uses chemical adhesives to achieve a strong bond between the fixing part and the substrate, and can provide very high tensile and shear strengths. It is suitable for applications requiring high bearing capacity, is easy to install, is not easily affected by the accuracy of the substrate holes, and has good fixing effect and wide applicability.

[0054] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Any equivalent changes based on the shape, structure and principle of the present invention should be included in the scope of protection of the present invention.
