Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a slotted C-shaped keel, a telescopic keel and a keel supporting structure. Background Art

[0002] Telescopic keel is a new type of building keel material, which is assembled and used by plugging, and can be extended to achieve the application of different keel installation sizes. For example, patent CN112726935A discloses a freely adjustable cladding keel, including a large cladding keel and a small cladding keel. The two keels are plugged together and can be freely extended and retracted during use. After adjusting to the appropriate position, the two keels are locked through the cooperation of the positioning holes, the continuous positioning holes and the positioning blocks, which is convenient to use.

[0003] When the keel is produced, the size of the large covering keel is generally relatively fixed, and the length of the small covering keel needs to be cut in advance according to the size requirements of the ceiling on site, and then the factory produces the small covering keel of appropriate length according to the cutting size. Due to the diversity of size requirements during the ceiling decoration process, it is necessary to produce small covering keels of various lengths. After the keel arrives at the installation site, the construction workers need to sort the small covering keels used in different lifting positions, which takes a lot of time. In addition, since the sizes of keels at different positions are slightly different, sorting errors often occur, causing confusion in on-site use, affecting construction efficiency, wasting materials, and also affecting the promotion and application of telescopic keels. Summary of the invention

[0004] In order to solve the problems in the prior art, the utility model patent designs a slotted C-shaped keel and a keel support structure to solve the problem that the existing telescopic keel is difficult to use on site.

[0005] The technical solution adopted by the utility model is that the slotted C-shaped keel comprises a C-shaped keel body, and the top ends of the two side walls of the keel body are provided with a plurality of engaging grooves along the length direction.

[0006] Furthermore, the top ends of the two side walls of the keel body are provided with V-shaped grooves at the front side of each engaging groove along the length direction.

[0007] Furthermore, the middle parts of the two side wall plates of the keel body are respectively bent to form first reinforcing rib grooves.

[0008] Furthermore, the keel body is bent and formed with second reinforcing rib grooves at the lower sides of the slotted sections at the tops of the two side wall plates.

[0009] Furthermore, the two side wall plates of the keel body are evenly arranged with a plurality of connection holes along the length direction.

[0010] Furthermore, the top ends of the two side wall plates of the keel body are bent into a U-shaped groove or a C-shaped groove.

[0011] Furthermore, the groove walls on both sides of the V-shaped groove of the keel body are in a smooth arc shape.

[0012] Furthermore, the top corner of the end of the keel body is chamfered to form a smooth arc-shaped inclined surface, and the keel body is also provided with a locking groove on the inner side of the arc-shaped inclined surface at the end.

[0013] Furthermore, the multiple V-shaped grooves and snap-fit ​​grooves on the keel body are evenly arranged along the length direction, and the interval between adjacent V-shaped grooves or snap-fit ​​grooves is 50 mm.

[0014] The utility model patent also discloses a telescopic keel, which includes the slotted C-shaped keel and the large keel as described above. The slotted C-shaped keel and the large keel have the same appearance. The slotted C-shaped keel is slidably inserted into the large keel, and positioning holes are respectively opened on the two side wall panels of the large keel.

[0015] The utility model patent also discloses a keel support structure, which includes the telescopic keel and the U-shaped side keel as described above, the arc-shaped inclined surface end of the slotted C-shaped keel of the telescopic keel is inserted into the U-shaped clamping cavity of the side keel, and the end of the upper side wall plate of the side keel is bent with a hook, and the hook is engaged in the engagement groove at the end of the slotted C-shaped keel.

[0016] Compared with the prior art, the advancement of the slotted C-shaped keel designed by the utility model patent lies in that: a plurality of V-grooves are evenly arranged along the length direction of the keel body. When in use, there is no need to cut the keel in advance according to the size requirements for on-site use. It only needs to be cut and used along the V-groove according to the use requirements, which reduces the cutting of keels and on-site sorting before construction, and greatly improves the convenience of using the keel; the groove walls on both sides of the V-groove are smooth arc-shaped, which is convenient for quick connection with side keels and large keels after cutting; the wall panels on both sides of the keel body are bent and formed with a first reinforcing rib groove and a second reinforcing rib groove, respectively, so that the keel has better rigidity, ensuring that the keel still has good shear resistance after slotting.
