Description

Technical Field

[0001] This article relates to building technology, particularly a keel frame structure and wall structure. Background Technology

[0002] Along with the development of the construction industry, the interior decoration industry has made significant progress. Lightweight steel keel partition walls are being used more and more widely, and they are composed of lightweight steel keels of different cross-sectional specifications.

[0003] The horizontal and vertical studs of lightweight steel keel partition walls are typically connected manually first, and then secured with rivets. The installation of gypsum board (or other facing materials) with the keel structural frame usually uses self-tapping screws spaced 300mm apart. The above installation methods have the following problems: First, efficiency briefing during the construction process.

[0004] Secondly, the surface of the board is easily damaged: When connecting the gypsum board (or other facing materials) to the keel structural frame with self-tapping screws, excessive force can easily damage the surface of the board, causing unnecessary losses such as rework.

[0005] Third, difficulty in positioning and connection: If the decorative surface is a plaster layer, the structural frame is usually connected to the keel in layers and staggered joints using double-sided double-layer gypsum board (or other facing materials). After the first layer of board is installed, it completely covers the keel frame. When installing the second layer of board, it is impossible to accurately find the position of the keel. Usually, a magnet is used to simulate positioning, which easily causes the second layer of board to be unable to be fully and correctly connected to the keel during the installation process. Later, delamination and peeling are likely to occur.

[0006] Fourth, the structural frame of the partition wall has poor stability and strength, especially when the traditional double-sided double-layer board is changed to double-sided single-layer, the keel is made of single-board rolled and shaped, and the overall keel structure relies on the surface gypsum board for skin fixation. Only after the two are connected can the stability and strength of the overall partition wall be guaranteed. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0036] like Figure 1-12 As shown, this application embodiment provides a keel frame structure 100, which is a structural system that can be used for the rapid installation of lightweight steel keel partition walls.

[0037] like Figure 1-2 As shown, the keel frame structure 100 of this application embodiment includes: multiple keels 1 spliced ​​into a frame structure, and connecting clips 2 connecting two keels 1a and 1b that are connected at corners to each other.

[0038] In this embodiment, the two keels 1a and 1b are connected at a 90-degree angle, i.e., they are spliced ​​vertically. Of course, the two keels 1a and 1b can also be connected at an angle less than 90 degrees or greater than 90 degrees. The specific design can be based on the actual situation and is not limited here. The connecting clip 2 connects the planes of the two keels 1a and 1b forming the inner corner, thereby maintaining the flatness of the plane formed by the frame structure.

[0039] Among them, the two keels 1a and 1b can be two spliced ​​frame keels, two spliced ​​middle reinforcing keels, or a frame keel and a reinforcing keel spliced ​​together; there is no limitation here.

[0040] like Figure 3 , Figure 4 As shown, the keel 1 includes a main body connecting portion 10 that extends along its length, and the main body connecting portion 10 includes opposing first sides 10a ( Figure 3 (right side) and second side 10b ( Figure 3 (left side), and the opposite third side 10c ( Figure 3 (upper side) and fourth side 10d ( Figure 3 (Lower side of the middle). In this embodiment, the cross-section of the main connecting part 10 is U-shaped.

[0041] The keel 1 also includes a slot portion provided on at least one of the first side 10a and the second side 10b of the main body connecting portion 10, and a snap-fit ​​connection structure 13 provided on at least one end face of the third side 10c and the fourth side 10d. The connecting clip 2 is snapped into the snap-fit ​​connection structure 13 of the two keels 1a and 1b that are connected at an angle to each other.

[0042] The side plate of the slot section and the main body connection section 10 forms a U-shaped cross section (see reference). Figure 2 The area within the dashed box is set as insert plate 3 (see section 3). Figure 9(As shown). In this embodiment, there are two slots, namely a first slot 11 located on the first side 10a of the main body connecting part 10 and a second slot 12 located on the second side 10b.

[0043] The keel 1 of the keel frame structure 100 in this application embodiment can be spliced ​​together by connecting clips 2 through the main body connecting part 10. At the same time, the slot parts 11 and 12 can realize the insertion and installation of the board, which is convenient and efficient, and avoids the problems of cumbersome installation, board damage and positioning difficulties caused by nailing installation.

[0044] like Figure 4 As shown, at least one latch is provided on the end face of the third side 10c and the end face of the fourth side 10d of the main body connecting part 10, forming a latching connection structure 13. In this embodiment, there are two latches: a first latch 131 on the end face of the third side 10c and a second latch 132 on the end face of the fourth side 10d. In this embodiment, the end face of the third side 10c of the main body connecting part 10 is an unclosed end face, forming the first latch 131, while the end face of the fourth side 10d is concave, forming the second latch 132. The first latch 131 and the second latch 132 facilitate the movement of the connecting member 2 along the extending direction of the first latch 131 and the second latch 132.

[0045] In one exemplary embodiment, the end faces of the third side 10c and the fourth side 10d of the main body connecting portion 10 are closed end faces, and the first latch 131 and the second latch 132 are multiple openings respectively provided on the end faces of the third side 10c and the fourth side 10d. Of course, the snap-fit ​​connection structure 13 can also be formed in other ways, mainly to realize the snap-fit ​​engagement with the connecting clip 2, and the specific structural shape is not limited here.

[0046] like Figure 3 As shown, the main body connecting part 10 includes a first side plate 101 and a second side plate 102 that extend along its length and are disposed opposite each other, and a first connecting plate 103 that connects the first side plate 101 and the second side plate 102. The first side plate 101 and the second side plate 102 are spaced apart to form an isolation gap 104.

[0047] like Figure 4 As shown, both the first side plate 101 and the second side plate 102 have an inwardly bent first flange 105 at one end located on the third side 10c. A first latch 131 is formed between the two first flanges 105, and the first latch 131 extends along the entire length of the main body connecting portion 10. The first flange 105 may also be bent outward, which is not limited here.

[0048] Both the first side plate 101 and the second side plate 102 have inwardly bent second flanges 106 at one end located on the fourth side 10d. The two second flanges 106 form a second latch 132, which extends along the entire length of the main body connecting portion 10. The second flanges 106 can also be bent outwards; this is not limited here. Figure 4 As shown, along the direction from the third side 10c to the fourth side 10d of the main body connecting portion 10, the first connecting plate 103 is located between the first bayonet 131 and the second bayonet 132, and divides the isolation gap 104 into a first isolation interval 1041 and a second isolation interval 1042. The first isolation interval 1041 and the second isolation interval 1042 are configured to allow the insertion of a partition plate 4 (see Figure 1042). Figure 10 (As shown).

[0049] like Figure 4 As shown, the first slot portion 11 includes a first clamping plate 110 located outside the first side plate 101 and spaced apart from the first side plate 101, and a second connecting plate 111 connecting the first clamping plate 110 and the first side plate 101. The first clamping plate 110 extends along the longitudinal direction of the main body connecting portion 10, and the plate surface of the first clamping plate 110 is opposite to the plate surface of the first side plate 101, with the gap between them forming a first clamping groove 112, which extends along the longitudinal direction of the main body connecting portion 10.

[0050] Along the direction from the third side 10c to the fourth side 10d of the main body connecting portion 10, the second connecting plate 111 is located between the two ends of the first clamping plate 110, dividing the first clamping groove 112 into a first slot 112a and a second slot 112b. The first slot 112a and the second slot 112b are respectively configured as insert plates 3 (see reference). Figure 9 (As shown).

[0051] Along the direction from the third side 10c of the main body connecting portion 10 to the fourth side 10d, the height of the first side plate 101 is higher than the height of the first clamping plate 110, and along the direction from the fourth side 10d of the main body connecting portion 10 to the third side 10c, the height of the first side plate 101 is also higher than the height of the first clamping plate 110.

[0052] like Figure 4 As shown, the second slot portion 12 includes a second clamping plate 120 located outside the second side plate 102 and spaced apart from the second side plate 102, and a third connecting plate 121 connecting the second clamping plate 120 and the second side plate 102. The second clamping plate 120 extends along the longitudinal direction of the main body connecting portion 10. The plate surface of the second clamping plate 120 is opposite to the plate surface of the second side plate 102, and the gap between them forms a second clamping groove 122, which extends along the longitudinal direction of the main body connecting portion 10.

[0053] Along the direction from the third side 10c to the fourth side 10d of the main body connecting part 10, the third connecting plate 121 is located between the two ends of the second clamping plate 120, dividing the second clamping groove 122 into a third slot 122a and a fourth slot 122b, and the third slot 122a and the fourth slot 122b are respectively configured as insert plates 3.

[0054] Along the direction from the third side 10c of the main body connecting portion 10 to the fourth side 10d, the height of the second side plate 102 is higher than the height of the second clamping plate 120, and along the direction from the fourth side 10d of the main body connecting portion 10 to the third side 10c, the height of the second side plate 102 is also higher than the height of the second clamping plate 120.

[0055] The clamping plate and connecting plate of the keel 1 in this embodiment adopt a high-low side design, which makes it more flexible when inserting the plates. At the same time, it is easier to nail the second layer of plates when installing them on the outside (the nailing point is on the high side). The high side is provided with a secondary bend, which increases the strength and prevents cuts.

[0056] In this embodiment, the keel 1 is formed by integral bending of the substrate. The first side plate 101 and the second side plate 102 are single-layer galvanized sheets, and the first clamping plate 110 and the second clamping plate 120 are double-layer galvanized sheets, which makes the overall strength of the keel 1 higher and its impact resistance higher.

[0057] In this embodiment of the application, the opening position of the middle U-shaped main body connecting part 10 of the keel 1 is designed (see...). Figure 4 The opening and closing positions of the end face of the third side 10c (see...) Figure 4 The fourth side (10d) has a concave opening on the end face. Both sides are designed with equal-sized double-layer galvanized steel concave arc structures. Simultaneously, a concave space 1042 is provided at the closed position to facilitate the connection of the connecting clips 2 while simultaneously increasing the overall strength and impact resistance of the keel 1. (Double concave arc angles are referenced.) Figure 4 The design of the inner flange structure allows for arbitrary horizontal or vertical movement of the card.

[0058] It should be noted that in existing technologies, keel partition walls mostly use horizontal U-shaped keels to connect and fix to the building floor slab using expansion bolts or steel nails. The connection between the horizontal U-shaped keels and the vertical C-shaped keels is conventionally achieved by manually drilling holes and then connecting and fixing them by nailing or riveting. This presents the following problems: First, the surface flatness of the gypsum board is poor. When sealing the outer layer with gypsum board, the protruding nail heads during keel connection often cause unevenness on the board surface, significantly impacting later construction. Second, the standardization of keel types is low. Existing light steel keel partition walls require combinations of various models and specifications of keels to be installed, resulting in a complex installation process, low standardization, numerous types, and high wastage. Third, the production process results in high resource consumption because it requires the combination of multiple types of keel, leading to complex production lines (one type of keel corresponds to one production line), high space occupancy, low per capita output, and increased carbon emissions during production. Fourth, the installation and delivery quality is low. Traditional keel partition wall installation requires manual cutting of concave openings, followed by fixing with self-tapping screws or rivets, resulting in inconsistent on-site delivery standards and low timeliness. Fifth, insufficient construction standards easily lead to rework. The installation of gypsum board (or other facing materials) and the keel structural frame typically uses self-tapping screws spaced 300mm apart for connection and fixation. Inefficient construction processes mean that excessive force applied when connecting gypsum board (or other facing materials) to the keel structural frame with self-tapping screws can easily damage the board surface, causing unnecessary losses such as rework. Sixth, with the rise of prefabricated construction technology, there is a strong demand for the efficiency and stability of the structural frame installation of partition walls, especially when adjusting traditional double-sided, double-layer boards to double-sided, single-layer boards. The unclear keel position makes installation inconvenient.

[0059] The keel 1 in this embodiment can achieve double-sided plug-in assembly, and the overall cross-section adopts a HUH-type cross-section structure design. The double H-type structure on both sides (slot parts 11, 12) adopts a high-low side design (high sides 101, 102 are single-layer galvanized sheets, and low sides 110, 120 are double-layer galvanized sheets), which makes it more flexible in the use of sheet 3 (gypsum board or other facing sheets), and at the same time facilitates easier nailing when installing sheet 3 (gypsum board or other facing sheets) or prefabricated decorative sheets on the outside (the nailing point is on the high side). A secondary bend is provided on the high side, which increases strength and also prevents cuts. The middle U-shaped main connecting part 10 has two open and closed positions 1041 and 1042, each with a double-layer galvanized sheet concave arc structure (flanged edge) of equal size. At the same time, the closed position 1042 has a concave space, which facilitates the connection of the connecting clip 2 and makes the overall strength of the keel 2 higher and its impact resistance higher. The design of the double-sided concave arc corner (jaw) also allows the connecting clip 2 to be moved and positioned at any position of the horizontal keel in the upper, lower and middle positions of the keel frame structure, according to the size requirements, so as to facilitate the connection with the longitudinal keel.

[0060] The keel 1 in this embodiment has a more stable and flexible overall structure, which can meet the requirements of convenient and standardized assembly in any form.

[0061] like Figure 5 , Figure 6 As shown, the connecting clip 2 in this embodiment includes a first substrate 21 and a second substrate 22 connected to the first substrate 21 and forming a corner. The back of the first substrate 21 and the second substrate 22 are respectively provided with multiple clips. Specifically, the clips 211 and 212 of the first substrate 21 engage with the snap-fit ​​connection structure 13 of the first keel 1a of the two corner-jointed keels 1, and the clips 221 and 222 of the second substrate 22 engage with the snap-fit ​​connection structure 13 of the second keel 1b of the two keels 1.

[0062] In this embodiment, the first substrate 21 and the second substrate 22 are connected at a 90-degree angle. Of course, they can also be connected at an angle greater than 90 degrees or less than 90 degrees, and this is not limited here.

[0063] like Figure 5 As shown, the second substrate 22 can rotate horizontally based on the plane of the first substrate 21, either clockwise or counterclockwise, facilitating installation on various wall types, such as flat or curved walls, and improving the convenience and practicality of keel installation.

[0064] In one exemplary embodiment, such as Figure 12 As shown, when the wall is curved, the top and bottom joists L have rounded corners. When connected to the longitudinal joists 1, the contact point between the lateral rounded corners and the longitudinal joists 1 cannot be kept on a parallel plane, causing connection points. If the connector cannot rotate freely, a connection cannot be formed. In this embodiment, the second base plate 22 of the connecting clip 2 can rotate horizontally based on the plane of the first base plate 21, and can rotate counterclockwise or clockwise, which facilitates the installation of the joists on the curved wall.

[0065] like Figure 5 As shown, the connecting clip 2 also includes a connecting portion 23 that connects the first substrate 21 and the second substrate 22. The connecting portion 23 extends from the side of the second substrate 22 that forms an angle with the first substrate 21 to the upper surface of the inner plate of the first substrate 21, and is rotatably connected to the first substrate 23 via a connecting shaft 24.

[0066] The plurality of latches provided on the back side of the first substrate 21 include a first latch 211 and a second latch 212. The first latch 211 and the second latch 212 are spaced apart along the transverse direction (Y direction) of the first substrate 21 and extend along the longitudinal direction (perpendicular to the Y direction) of the first substrate 21.

[0067] The second substrate 22 has a plurality of latches on its back side, including a third latch 221 and a fourth latch 222. The third latch 221 and the fourth latch 222 are spaced apart along the transverse direction (Y direction) of the second substrate 22 and extend along the longitudinal direction (perpendicular to the Y direction) of the second substrate 22.

[0068] Both the first buckle 211 and the second buckle 212 extend toward the back away from the first base plate 21 and are bent in opposite or opposite directions to form hooks. The hooks of the first buckle 211 and the second buckle 212 are engaged with the first latch 131 or the second latch 132 of the first keel 1a for hooking.

[0069] The third buckle 221 and the fourth buckle 222 both extend toward the back away from the second base plate 22 and are bent in opposite or opposite directions to form hooks. The hooks of the third buckle 221 and the fourth buckle 222 are engaged with the first latch 131 or the second latch 132 of the second keel 1b for hooking.

[0070] The first buckle 211 and the second buckle 212 are formed by punching and bending the first substrate 21, and the third buckle 221 and the fourth buckle 222 are formed by punching and bending the second substrate 22. The first buckle 211 and the second buckle 212 are provided with rounded corners on both sides of their ends, and the third buckle 221 and the fourth buckle 222 are also provided with rounded corners on both sides of their ends, so as to facilitate the mounting of the keel 1.

[0071] In this embodiment, the surface of the connecting clip 2 is covered with a sound insulation pad (not shown), which can avoid the problem of large-area resonance caused by single-point micro-vibration of the keel 1. At the same time, the sound insulation pad also has the function of blocking sound transmission through metal, thus improving the overall sound insulation performance.

[0072] The connecting clip 2 in this embodiment can rotate and adopts a right-angle corner design. Both sides are covered with sound-insulating and vibration-damping rubber pads. This ensures the right angle requirements for the connection between the horizontal keel 1a and the vertical keel 1b, and the connection between the vertical keel 1a and the building floor slab. At the same time, it avoids the problem of large-area resonance caused by single-point micro-vibration of the keel 1. In addition, the sound-insulating and vibration-damping point also has the function of blocking sound transmission through metal, thus improving the overall sound insulation performance.

[0073] The connecting clip 2 in this embodiment is formed by stamping, bending, and punching in one piece. It features two outwardly protruding arc-shaped hook steel plates (clasps 211, 212, 221, 222) in both the horizontal and vertical directions. Each hook steel plate (clasp 211, 212, 221, 222) has rounded corners at both ends, which facilitates smoother engagement with the U-shaped concave rounded corners (flared edges) of the keel 1. Furthermore, the horizontal and vertical steel plates 21 and 22 are designed with a separation principle. One side of one steel plate 22 extends a connecting steel plate 23 in the vertical direction. This connecting plate connects to the horizontal steel plate 21, providing a secure connection while allowing for 360° rotation based on the connection point of the internal threaded connecting rod 24. This design enhances the convenience and practicality of installing and using the curved wall and keel 1.

[0074] like Figure 7 As shown, in this embodiment of the application, when the keel 1 and the connecting clip 2 are engaged and fastened, the connecting clip 2 can engage and fasten with the snap-fit ​​connection structure 13 on the third side 10c end face of the main body connecting portion 10 of the keel 1. The first clip 211 and the second clip 212 provided on the back of the first base plate 21 of the connecting clip 2, or the third clip 221 and the fourth clip 222 provided on the back of the second base plate 22, engage and hook with the first slot of the main body connecting portion 10.

[0075] The connecting clip 2 can also engage with the snap-fit ​​connection structure 13 on the fourth side 10d end face of the main body connecting part 10 of the keel 1. The first snap 211 and the second snap 212 provided on the back of the first base plate 21 of the connecting clip 2, or the third snap 221 and the fourth snap 222 provided on the back of the second base plate 22, engage with the second snap-fit ​​of the main body connecting part 10.

[0076] It should be noted that Figure 7 The two connecting pieces 2 are only for describing the hanging method of the keel 1, and do not necessarily mean that both connecting pieces 2 are hung at the same time.

[0077] like Figure 8 , Figure 9 As shown in the embodiment of this application, when the connecting clip 2 is used to assemble multiple keels 1, one connecting clip 2 can connect two keels 1a and 1b that are connected to each other at an angle among the multiple keels 1. The two keels 1a and 1b include a horizontal keel 1a and a vertical keel 1b.

[0078] In this embodiment, the horizontal keel 1a and the vertical keel 1b are vertically spliced. The first buckle 211 and the second buckle 212 of the first base plate 21 of the connecting clip 2 engage with the first latch 131 or the second latch 132 of the horizontal keel 1a. The third buckle 221 and the fourth buckle 222 on the back of the second base plate 22 engage with the first latch 131 or the second latch 132 of the vertical keel 1b. Of course, the first buckle 211 and the second buckle 212 of the first base plate can also engage with the first latch 131 or the second latch 132 of the vertical keel 1b, and the third buckle 221 and the fourth buckle 222 on the back of the second base plate 22 can also engage with the first latch 131 or the second latch 132 of the horizontal keel 1a; this is not limited here.

[0079] like Figure 10 , Figure 11 As shown, this application embodiment also provides a wall structure, including the keel frame structure 100 described in any of the above claims, and the plate 3 inserted into the keel frame structure 100.

[0080] The keel frame structure 100 includes multiple horizontal keels 1a and vertical keels 1b connecting adjacent horizontal keels 1a. The two ends of the plate 3 along the vertical direction are respectively inserted into the slots on the same side of two adjacent horizontal keels 1a, and one end of the plate 3 along the horizontal direction is inserted into the slot on the same side of the vertical keel 1b connecting two adjacent horizontal keels 1a.

[0081] like Figure 9 As shown, the board 3 includes a first board 31 and a second board 32. The two vertical ends of the first board 31 are respectively inserted into the first clamping grooves 112 of two adjacent horizontal keels 1a, and the other horizontal end of the first board 31 is inserted into the first slot 112a or the second slot 112b of the first clamping groove 112 of the vertical keel 1b connecting the two adjacent horizontal keels 1a. The two vertical ends of the board 31 are respectively inserted into the first slot 112a or the second slot 112b of the first clamping groove 112 of the two adjacent horizontal keels 1a.

[0082] The two ends of the second plate 32 along the vertical direction are respectively inserted into the second clamping grooves 122 of two adjacent horizontal keels 1a, and one end of the second plate 32 along the horizontal direction is inserted into the third slot 122a or the fourth slot 122b of the second clamping groove 122 of the vertical keel 1b connecting the two adjacent horizontal keels 1a. The two ends of the plate 32 along the vertical direction are respectively inserted into the third slot 122a or the fourth slot 122b of the second clamping groove 122 of the two adjacent horizontal keels 1a.

[0083] The wall structure in this embodiment of the application also includes a partition 4 inserted into the keel frame structure 100, and sound-absorbing, sound-insulating, and fire-resistant rock wool materials. The two ends of the partition 4 along the vertical direction are respectively inserted into the isolation gap 104 of the main body connection part 10 of two adjacent horizontal keels 1a, and one end of the partition 4 along the horizontal direction is inserted into the isolation gap 104 of the vertical keel 1b connecting the two adjacent horizontal keels 1a.

[0084] The keel frame structure 100 and wall structure of this application embodiment enable nail-free double-sided plug-in quick installation of panels, providing a structural system for the rapid installation of lightweight steel keel partition walls. The keel frame structure 100 and wall structure of this application embodiment can adopt a uniform cross-sectional specification keel connection combination. The panels are connected and fixed nail-free (self-tapping screws, rivets) through pre-reserved slots 112a, 112b, 121a, and 122b on the keel 1. This combination mode, where the uniform cross-sectional specification keel 1 is installed, combined, and fixed through uniform snap-fit ​​components, provides a standard, flat, stable, and robust keel structure for the installation of secondary foundation layers and prefabricated decorative surface layers. This application's embodiment of the keel frame structure 100 and wall structure can utilize a type of keel, combined with the same snap-fit ​​connector, to complete the partition wall installation, which has profound significance: Firstly, the overall flatness is higher because it adopts a snap-fit ​​method and the front is nail-free. The surface sealing board has a high degree of flatness. When sealing the outer layer of gypsum board, the keel connection will not cause unevenness of the board surface due to the traditional nail head protrusion, thus improving the delivery quality. Secondly, the keel category is unified. The card-connected assembly keel 1 can replace the traditional partition wall keel combination form with various models (C type, U type, M type, Z type, etc.) and specifications through flexible arrangement in different horizontal and vertical directions. It has the advantages of simple installation process, higher standardization and low loss. Third, the production process has low resource consumption. Its characteristics are independence, a single type of keel can realize the application of the scenario, a single production line can meet the demand, low space occupancy, high per capita output value, and low carbon emissions during the production process. Fourth, high-quality delivery capability. Its structure is snap-fit, requiring very little on-site secondary processing, thus avoiding inconsistencies in standards caused by human factors from the source. Fifth, the construction standards are high. The panels (cladding panels or other cladding panels) are inserted and fixed through the slots of the keel prefabricated panels, eliminating the need for the panels to be connected to the keel frame by nailing, which makes the construction process more efficient. Sixth, it is more adaptable to the application of new prefabricated interior decoration industrialization products. The prefabricated construction process has strong requirements for the efficiency and stability of the structural frame installation of structural partition walls, especially when the traditional double-sided double-layer plates are adjusted to double-sided single-layer, and the keel positions need to be clarified to facilitate the installation of decorative surface plates. This double-sided plug-in keel structure can fully meet the corresponding requirements.

[0085] According to the actual situation, the present keel 1 is arranged in a transverse manner and connected and fixed to the floor surfaces (arranged on the top surface and the ground respectively) through special shooting nails or expansion bolts (usually fixed and connected by expansion bolts or steel shooting nails). Then the present keel 1 is arranged longitudinally at equal intervals, and the tops and bottoms of the transverse and longitudinal keels are connected through special connecting clips. If the strength needs to be improved, clamping pieces can be used to connect the present keels in the transverse arrangement. Through the matching relationship between the keels and the clamping pieces, the clamping assembly installation form can be realized, making it firmer and more stable, and the overall installation structure is more standard with higher efficiency.

[0086] According to requirements, the keel frame structure 100 can be filled with sound-absorbing and fire-resistant materials such as rock wool, and partition plates 4. At the same time, according to the process requirements of the decorative effect, a variety of base materials or decorative integrated materials such as wood, gypsum board, and cement board can be used in combination, so that the flexibility of its scenario application is higher.
