Description

Technical Field

[0001] This invention relates to a keel, and more particularly to a ceiling keel and keel assembly. Background Technology

[0002] Existing ceiling joists mostly adopt U-shaped or H-shaped structures, which have effective load-bearing capacity but small spans. In addition, existing ceiling joists can only be connected to the ceiling via bolts and cannot be used for independent ceilings, such as cleanroom ceilings. Cleanroom ceilings need to install many auxiliary equipment, such as air conditioners, ventilation ducts, and cables. Since cleanrooms are located inside the floor, their tops need to be connected to the ceiling. Therefore, existing ceiling joists cannot effectively support the auxiliary equipment. Summary of the Invention

[0003] To solve the above problems, the present invention provides a ceiling keel, the specific technical solution of which is as follows: A ceiling keel includes a keel body, the keel body being rectangular, both ends of the keel body having snap-fit ​​grooves and first snap-fit ​​protrusions at both ends of the snap-fit ​​grooves, and both sides of the keel body having connecting grooves.

[0004] Preferably, all four corners of the keel body are rounded corners.

[0005] A keel assembly includes: a ceiling keel, wherein two ceiling keels are arranged in parallel; a connecting keel, having the same structure as the keel body, wherein the connecting keel is disposed between the two ceiling keels and is inclined; a connector, which is connected to the ceiling keel and the connecting keel respectively; and a locking member, which is connected to the connector, the ceiling keel and the connecting keel respectively, so as to fix the connector to the ceiling keel and the connector.

[0006] Preferably, the connector includes a first connecting portion and a second connecting portion that are symmetrically arranged and form a V shape. The first connecting portion is U-shaped and is used to lock onto the ceiling joist and the connecting joist. Both sides of the first connecting portion are provided with first connecting holes for inserting the locking member.

[0007] Furthermore, there are at least two first connecting holes.

[0008] Preferably, the connector has a reinforcing protrusion for insertion into the snap-fit ​​groove.

[0009] Preferably, the connector has symmetrical second snap-fit ​​protrusions on both sides for insertion into the connecting groove.

[0010] Furthermore, a clearance groove is provided between the first connecting part and the second connecting part, and the clearance groove is used to be engaged with the ceiling keel.

[0011] Preferably, the locking element includes: a connecting rod for inserting into the connector, the ceiling joist, and the connecting joist; a locking rod disposed at one end of the connecting rod and forming an L-shape with the connecting rod; and a locking cap disposed at the other end of the connecting rod.

[0012] Furthermore, the length of the connecting rod is less than the length of the locking rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The ceiling keel provided by this invention can provide stronger structural stability in spaces with large spans and facilitates the installation of auxiliary equipment. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0016] like Figure 1 and Figure 2 As shown, a ceiling keel includes a keel body 1, which is rectangular. The two ends of the keel body 1 are symmetrically provided with snap-fit ​​grooves 11 and first snap-fit ​​protrusions 12 at both ends of the symmetrical snap-fit ​​grooves 11. The two sides of the keel body 1 are symmetrically provided with connecting grooves 13.

[0017] The snap-fit ​​groove 11 not only improves the strength of the keel body 1, but also facilitates the installation of standard parts such as T-bolts and T-nuts.

[0018] The connecting groove 13 facilitates the installation of the connector 3. The connecting groove 13 also increases the strength of the keel body 1. The connecting groove 13 and the snap-fit ​​groove 11 strengthen all four sides of the keel body 1, greatly improving the overall strength of the keel body 1. The overall force is balanced, which can effectively reduce the deformation of the keel during use. It also has a strong load-bearing capacity, making the bottom surface of the entire ceiling system flatter. It is especially suitable for large-area or large-span ceilings.

[0019] The snap-fit ​​connection allows for partial disassembly, eliminating the need for extensive removal when inspecting pipes, water, electricity, and air conditioning systems within the ceiling, thus reducing maintenance costs.

[0020] The four corners of the keel body 1 are all rounded corners 14. The rounded corners 14 eliminate stress concentration points and prevent the keel from deforming due to bumps during transportation or installation. At the same time, it improves the overall bending and torsional strength and is not easy to deform after long-term use. Example 2

[0021] like Figures 1 to 8 As shown, a keel assembly includes a ceiling keel, a connecting keel 2, a connector 3, and a locking member 4. Two ceiling keels are arranged parallel to each other vertically. The two ends of the connecting keel 2 are respectively connected to the two parallel ceiling keels, and the structure of the connecting keel 2 is the same as that of the keel body 1, meaning the connecting keel 2 is made from the keel body 1. The connecting keel 2 is inclined, forming a triangular support with the keel body 1 to improve overall strength. The connector 3 is connected to both the ceiling keel and the connecting keel 2. The locking member 4 connects the connector 3 to both the keel body 1 and the connecting keel 2, thus fixing the connector 3 to both the ceiling keel and the connector 3.

[0022] The ceiling joists and connecting joists 2 have completely identical structures, which reduces costs, facilitates inventory management, and allows for flexible switching between ceiling joists and connecting joists 2 during on-site construction, improving material utilization. At the same time, it eliminates directional requirements for the installation of connectors 3, reducing installation requirements.

[0023] The columns are located around the clean room. The two ends of the lower ceiling joists are installed on the columns. The upper ceiling joists are not connected to the ceiling. The upper ceiling joists form an integral frame structure with the lower ceiling joists through connectors 3. It has high strength and is not easily deformed. The spacing between the upper and lower joists can be adjusted through connectors 3 to accommodate auxiliary equipment.

[0024] The lower ceiling keel of the frame structure formed by the keel components can be installed with the ceiling through the snap-fit ​​groove 11, and the upper ceiling keel can be used to install panels to form a roof structure, or even serve as a floor structure. The keel components can be used to install auxiliary equipment, which can be installed through the snap-fit ​​groove 11 or the connecting groove 13.

[0025] The connector 3 includes a symmetrically arranged, V-shaped first connecting portion 31 and a second connecting portion 32, forming a 135-degree angle. The cross-section of the first connecting portion 31 is U-shaped, used to secure it to the ceiling joists and connecting joists 2. Both sides of the first connecting portion 31 have first connecting holes 34 for inserting locking elements 4. After the connector 3 is installed, holes are drilled in the ceiling joists and connecting joists 2 through the first connecting holes 34, and then the locking elements 4 are inserted. To improve the reliability, stability, and strength of the connection, there are at least two first connecting holes 34; usually, two are sufficient. Each connector 3 is connected to the connecting joists 2 and the ceiling joists via four locking elements 4.

[0026] The first connecting part 31 is provided with a reinforcing protrusion 33 for inserting into the snap-fit ​​groove 11. The reinforcing protrusion 33 can increase the strength of the connector 3 and can also be inserted into the snap-fit ​​groove 11 to achieve the positioning of the connector 3.

[0027] On both sides of the first connecting part 31, that is, on both sides of the first connecting part 31 and the second connecting part 32, there are symmetrical second snap-fit ​​protrusions 35 for inserting into the connecting groove 13. The second snap-fit ​​protrusions 35 are snapped into the connecting groove 13, so that the connector 3 will not fall off automatically, which facilitates drilling and installing the locking part 4. There is no need to fix the connector 3 with auxiliary tools during the assembly process, so that both hands can make large holes and install the locking part 4, which can effectively improve the assembly efficiency.

[0028] To prevent the second snap-fit ​​protrusion 35 from abutting against the side of the ceiling joist and thus preventing it from being inserted into the connecting groove 13, a clearance groove 36 is provided between the first connecting part 31 and the second connecting part 32. This clearance groove 36 is used to engage with the ceiling joist. The clearance groove 36 allows the second snap-fit ​​protrusion 35 to avoid the ceiling joist, enabling it to be effectively inserted into the connecting groove 13. Alternatively, the second snap-fit ​​protrusion 35 can be omitted during the stamping process at a position opposite the ceiling joist.

[0029] The locking component 4 includes a connecting rod 42, a locking rod 43, and a locking cap 41. The connecting rod 42 and the locking rod 43 form an L-shape and can be set vertically or nearly vertically. The locking cap 41 is located at the other end of the connecting rod 42. The connecting rod 42, the locking rod 43, and the locking cap 41 form an integral structure. The connecting rod 42 is used to insert into the connector 3, the ceiling joist, and the connecting joist 2. The locking rod 43 is used to insert into the interior of the ceiling joist and the connecting joist 2 and abut against the inner wall. The locking cap 41 abuts against the outer side of the connector 3. The locking cap 41 and the locking rod 43 connect the connector 3 to the ceiling joist and the connecting joist 2 before locking the component 4, preventing it from falling out of the first connecting hole 34. Furthermore, to improve the reliability of the locking component 4 connection, the length of the connecting rod 42 is less than the length of the locking rod 43, so that the locking component 4 is less likely to fall out of the first connecting hole 34. The length of the connecting rod 42 is slightly greater than the sum of the wall thickness of the connector 3 and the wall thickness of the joist body 1.
