Description

Technical Field

[0001] The invention relates to the technical field of building decoration engineering, in particular to a split combined closed dovetail groove skeleton system. Background Art

[0002] With the continuous development and progress of the construction industry, prefabricated building technology has gradually received widespread attention. In prefabricated partition walls, the keel is a key supporting structure, and its performance directly affects the quality and stability of the partition wall. Different building spaces have different requirements for the thickness of the partition wall. By connecting two vertical parallel keels and controlling the spacing between them, the required wall thickness can be accurately achieved to meet the requirements of architectural design for space separation, sound insulation, thermal insulation and other functions.

[0003] The design of traditional keels is usually relatively simple, with a single cross-sectional shape, mostly C-shaped, U-shaped, etc. These simple cross-sectional shapes have limited ability to resist bending, shearing and other forces, and are prone to deformation, yield failure and other problems during long-term use. In addition, the connection between adjacent vertical parallel keels is not convenient and efficient, and often requires the use of a large number of connectors for welding or the use of angle brackets for connection. Multiple cutting or welding may be required on site, resulting in low installation efficiency, increasing construction difficulty and cost. In addition, the protruding parts or welding points of the angle brackets may affect the flatness of subsequent wall decoration, requiring additional processing.

[0004] Based on the above situation, we propose a split combined closed dovetail slot skeleton system to solve the above problems. Summary of the invention

[0007] Preferably, the connecting member is an "J"-shaped connecting plate having a "J"-shaped cross section, and a second nail penetration hole is formed on the "J"-shaped connecting plate.

[0008] Preferably, the connecting member is an I-shaped connecting plate with an I-shaped cross section, and a second nail hole is formed on the I-shaped connecting plate.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0017] Reference Figure 1-Figure 13 As shown, a split combined closed dovetail groove skeleton system includes at least two vertically parallel keel bodies 1, whose cross-section is a closed structure, wherein the keel body 1 can be formed by rolling galvanized steel plates to ensure sufficient strength, rigidity and corrosion resistance. The thickness and specifications of the keel body 1 are selected according to design requirements. During processing, it can be bent by CNC bending or die stamping bending, and a dovetail groove 11 shape can be processed. The closed part is sealed by laser welding. Due to its unique shape, the closed dovetail groove 11 structure can better disperse stress and enhance rigidity when subjected to external force, reducing the possibility of deformation. The main body 1 includes a first connecting surface 12 and two second connecting surfaces 13. The first connecting surface 12 and the dovetail end of the dovetail groove 11 are on the same plane. The second connecting surfaces 13 are respectively located on both sides of the dovetail groove 11. A connecting piece 2 is also provided between two adjacent vertically parallel keel main bodies 1, which is mainly used to connect two adjacent keel main bodies 1. Among them, different specifications of connecting pieces 2 can be configured according to the thickness of the wall to meet different usage requirements. It also includes a connection positioning hole group, which includes a front hook wedge hole 3 opened on the first connecting surface 12 and a first nail hole 31 and a positioning hole 32 opened on the second connecting surface 13, such as Figure 4 As shown, the front hook wedge-shaped hole 3 can be shaped like a hook bottle hole, and can be used in conjunction with the hook-type outer panel hanging ear to facilitate installation of curtain walls, etc., and the spacing between two adjacent front hook wedge-shaped holes 3 can be between 70mm-80mm, preferably 75mm, the first nail hole 31 is circular, the spacing between two adjacent first nail holes 31 is between 20mm-30mm, preferably 25mm, the positioning hole 32 is strip-shaped, the spacing between two adjacent positioning holes 32 can be between 70mm-80mm, preferably 75mm, meeting the modular matching design of various assembly types, with a wider range of adaptability, and the gap between two adjacent connectors 2 can be used for the installation of pipelines at a later stage; Among them, when it is necessary to install the transverse keel or C-shaped purlin, the transverse keel can be a ceiling keel and a ground keel perpendicular to the vertically arranged keel main body 1, and the transverse connecting member 4 can be connected to the second connecting surface 13, and the transverse connecting member 4 includes a transverse portion 41 and a longitudinal portion 42 integrally connected to the transverse portion 41, and the longitudinal portion 42 can be provided with a plug plate 43 folded on one side of the longitudinal portion 42, and the transverse connecting member 4 is initially positioned on the second connecting surface 13 by inserting the plug plate 43 into the positioning hole 32 on the second connecting surface 13, and then the positioning hole 32 on the longitudinal portion 42 is aligned with the positioning hole 32 on the second connecting surface 13, and the connection and fixation are performed by penetrating with fixing rivets or self-tapping screws, and then the transverse keel to be installed is inserted into one end of the transverse portion 41, and the position of the transverse keel is fine-tuned through the long strip positioning hole 32 on the transverse portion 41, and then the transverse keel is penetrated and fixed by fixing rivets or self-tapping screws to achieve the connection between the transverse keel and the keel main body 1; In order to adapt to the uneven ground conditions at the construction site, a lifting and adjusting component is also included at the bottom of the vertically arranged keel body 1 for adjusting its height. Specifically, the lifting and adjusting component includes a support plate body 5, a support limit frame 51 arranged on the support plate body 5, a lifting and adjusting gasket 52 slidably connected to the support limit frame 51, and a height adjustment bolt 53 that passes through the lifting and adjusting gasket 52 and is threadedly connected to the lifting and adjusting gasket 52. The bottom end of the height adjustment bolt 53 is rotatably connected to the support plate body 5, the support plate body 5 can be installed inside the ground keel, the bottom end of the keel body 1 can be inserted into the support limit frame 51, and its bottom is in conflict with the lifting and adjusting pad. At this time, the height adjustment bolt 53 is located in the dovetail groove 11 of the keel body 1 When the height of the construction site is uneven, by rotating the height adjustment bolt 53, the lifting and adjusting gasket 52 is slidably connected to the support limit frame 51 and is threadedly connected to the height adjustment bolt 53. Therefore, when the height adjustment bolt 53 is rotated, the lifting and adjusting gasket 52 will not rotate accordingly but will slide vertically upward or downward along the length extension direction of the support limit frame 51, thereby adjusting the height of the keel body 1 at its upper end, adapting to different installation scenarios, being quick and convenient, and without the need to cut or weld the keel body 1, etc., and in order to facilitate the rotation operation of the height adjustment bolt 53 in the dovetail groove 11, a polygonal notch, such as a hexagon, can be opened on the upper end surface of the height adjustment bolt 53, so as to facilitate the use of an Allen wrench for operation and rotation.

[0018] Reference Figure 1 , Figure 6 as well as Figure 7As shown, a first embodiment provided by the present invention is that the connecting member 2 is an I-shaped connecting plate 21 having an I-shaped cross section, and a second nail hole 23 is provided on the I-shaped connecting plate 21. After the second nail hole 23 on the I-shaped connecting plate 21 is aligned with the second nail hole 23 on the second connecting surface 13, the two are connected by fixing rivets or self-tapping screws. After the connection, the left-right symmetrical position of the I-shaped connecting plate can be recessed between two adjacent keel bodies 1, which is convenient for subsequent filling of rock wool, etc.

[0019] Reference Figure 2 , Figure 8 as well as Fig. 9 As shown, the second embodiment provided by the present invention is that the connecting member 2 is an I-shaped connecting plate 22 with an I-shaped cross-section, and a second nail hole 23 is provided on the I-shaped connecting plate 22. The I-shaped connecting plate 22 has better rigidity, more direct and effective force transmission, and is simpler to manufacture than the I-shaped connecting plate. In addition, since the surface of the I-shaped connecting plate 22 is planar, it is convenient to perform subsequent welding or rib pressing operations thereon, which can further increase the rigidity and has better adaptability. However, compared with the I-shaped connecting plate 21 in the first embodiment, since the I-shaped connecting plate 22 is planar and has no contact with the side walls opposite to the two keel bodies 1, it is more troublesome to fill it with rock wool or the like later.

[0020] It should be noted that the connecting member 2 is not limited to the I-shaped connecting plate 21 and the straight connecting plate 22, and the specifications and dimensions are not limited. It is used to fix two keel bodies 1, and the size can be flexibly adjusted according to the thickness of the wall panel.

[0021] Furthermore, hook portions 24 are provided at the four corners of the connecting member 2. The hook portions 24 can be integrally formed with the connecting member 2, and the hook portions 24 are used to cooperate with the positioning holes 32 to achieve auxiliary positioning of the connecting member 2. They can be correspondingly inserted into the positioning holes 32 on the second connecting surface 13, which is convenient for workers to assemble and position.

[0022] Further, referring to 13, the interior of the dovetail groove 11 is filled with an isolation strip 6, and the isolation strip 6 and the EPDM foam strip are used. After the partition keel is installed, the inner side of the panel can be used to press the isolation strip 6 to ensure sufficient air tightness, prevent the sound from passing through the gap and going around the back of the partition wall, enhance the sound insulation ability, and prevent the penetration of various gases, dust, and harmful bacteria. There is no air leakage hole after the overall assembly.
