Description
Technical Field
[0001] The utility model relates to the technical field of building materials, in particular to a three-cavity partition wall keel and a partition wall keel supporting structure. Background Art
[0002] After the construction of current buildings, especially commercial buildings, is completed, the interior is basically a frame structure without partition walls. When decorating, users will construct partition walls according to their own needs. The partition keel is the main component of the supporting structure of the partition wall. There are many structural forms of existing partition keels, such as "SHS" type, "CHC" type, etc. The supporting parts on both sides of the keel and the connecting part in the middle are used to install and fix the partition board (mostly gypsum board). The three-layer partition board forms two cavities, which can achieve good sound insulation effect. However, in the decoration of some special commercial rooms, the double cavity still cannot meet the sound insulation requirements of use.
[0003] Moreover, the existing partition wall keel construction operation is relatively complicated. Since a partition wall board in the middle of the partition wall keel needs to have both ends of the partition wall board inserted into the slots of two adjacent partition wall keels during construction, each time a partition wall keel is installed, it is necessary to plug and pre-fix a partition wall board, and then install a partition wall keel, and so on. The entire construction process requires the collaboration of multiple people to complete, with low construction efficiency and high labor costs. Summary of the invention
[0004] In order to solve the problems in the prior art, the utility model patent designs a three-cavity partition wall keel and a partition wall keel supporting structure to solve the problems of limited sound insulation effect and low construction efficiency of the partition wall formed by the existing partition wall keels.
[0005] The technical solution adopted by the utility model is: a three-cavity partition wall keel, the three-cavity partition wall keel comprises supporting parts on both sides and a connecting part in the middle, and two partition board connecting positions are respectively formed on both sides of the connecting part.
[0006] Furthermore, the three-chamber partition wall keel includes a main keel, a first U-shaped sub-keel and a second U-shaped sub-keel. The first U-shaped sub-keel and the second U-shaped sub-keel are respectively assembled on both sides of the connecting part in the middle of the main keel. The first U-shaped sub-keel and the second U-shaped sub-keel form partition connection positions with the main keel on both sides.
[0007] Furthermore, the main keel is bent in a "bow" shape, and the first U-shaped sub-bone and the second U-shaped sub-bone are respectively connected to both sides of the plate body of the middle bending section of the main keel, the first U-shaped sub-bone is located on the convex side of the middle bending section of the main keel, and its two sides respectively form "L"-shaped partition connection positions, and the second U-shaped sub-bone is located on the concave side of the middle bending section of the main keel, and its two sides respectively form "U"-shaped partition connection positions with the main keel.
[0008] Furthermore, the top ends of the two wing plates of the second U-shaped auxiliary bone are bent inwards respectively.
[0009] Furthermore, the bending portions of the main keel located on both sides of the top end of the wing plate of the second U-shaped secondary keel are smoothly curved.
[0010] Or as another design, the bending parts of the main keel located on both sides of the top end of the wing plate of the second U-shaped secondary keel are formed with inclined surfaces.
[0011] Furthermore, a plurality of sound insulation holes are evenly distributed on the inclined surfaces on both sides of the main keel.
[0012] Furthermore, reinforcing ribs are bent and formed on the plates at both ends of the main keel.
[0013] Furthermore, a plurality of through holes are respectively formed on the connecting plates of the first U-shaped auxiliary bone, the second U-shaped auxiliary bone and the main keel.
[0014] The utility model patent also provides a partition wall keel support structure, which includes top and bottom keels installed at the upper and lower ends respectively, and the top and bottom keels are U-shaped grooves, and a number of connection holes are evenly distributed on the bottom plate and the side plates thereof, and a number of three-cavity partition wall keels as described above are evenly arranged and fixed between the top and bottom keels at the upper and lower ends.
[0015] Compared with the prior art, the three-chamber partition keel designed in the utility model patent has the following advantages:
[0016] Two partition board connection positions are formed on both sides of the connection part in the middle of the partition wall keel, which can connect two layers of partition wall boards. Together with the partition wall boards connected to the supporting parts on both sides of the keel, four layers of partition wall boards can form three partition cavities, further improving the sound insulation effect of the partition wall.
[0017] The top ends of the two wing plates of the second U-shaped sub-bone are bent inwards respectively, and the bending parts of the main keel on both sides of the second U-shaped sub-bone are bent in a smooth arc shape or bent to form an inclined surface, so that the opening of the clamping cavity formed on both sides of the second U-shaped sub-bone becomes larger, which is convenient for inserting the partition wall panel during application, reduces the construction difficulty and improves the construction efficiency.
[0018] The main keel and the U-shaped sub-keels on both sides adopt an assembled structure. Compared with the traditional partition keel integrated bending and forming production method, the investment cost of production equipment is low and the material loss is less.
[0019] There are corresponding perforations on the connecting plates between the main keel and the U-shaped sub-keels on both sides, and there are also several sound insulation holes on the bent inclined plates on both sides of the second U-shaped sub-keel of the main keel, which can effectively reduce the sound conduction effect of the partition keel and further improve the sound insulation capacity of the partition cavity.

DETAILED DESCRIPTION
[0028] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the utility model are clearly and completely described, and the described embodiments are only embodiments of a part of the invention, not all of it. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention. Example 1
[0029] like Figure 1As shown, the utility model patent designs a first embodiment of a three-chamber partition wall keel. In this embodiment, the three-chamber partition wall keel includes a main keel 1, a first U-shaped auxiliary keel 2 and a second U-shaped auxiliary keel 3. The main keel 1 is bent in a "bow" shape, including support parts 11 on both sides and a connecting part 12 in the middle. The first U-shaped auxiliary keel 2 and the second U-shaped auxiliary keel 3 are respectively connected to the two sides of the bending section plate body of the middle connecting part 12 of the main keel 1. The width of the bottom plate of the first U-shaped auxiliary keel 2 and the second U-shaped auxiliary keel 3 is less than the plate body width of the middle connecting part 12 of the main keel 1. The first U-shaped auxiliary keel 2 is located on the convex side of the middle bending section of the main keel 1, and its two sides respectively form an "L"-shaped L-shaped partition connection position 21, and the second U-shaped auxiliary keel 3 is located on the concave side of the middle bending section of the main keel 1, and its two sides respectively form a "U"-shaped U-shaped partition connection position 31 with the main keel 1.
[0030] The top ends of the two wing plates of the second U-shaped sub-bone 3 are respectively bent inward to form a closed structure. The bent portions of the main keel 1 located on both sides of the top end of the wing plate of the second U-shaped sub-bone 3 are respectively formed with inclined surfaces 13 by bending. The inclined surfaces 13 on both sides of the main keel 1 and the closed structure of the top end of the wing plate of the second U-shaped sub-bone 3 together constitute a gradual opening structure of the U-shaped partition connection position 31, which is convenient for inserting the partition into the U-shaped partition connection position 31 when used.
[0031] In addition, a plurality of sound insulation holes 14 are evenly distributed on the inclined surfaces 13 on both sides of the main keel 1, and a plurality of through holes 15 are correspondingly opened on the connecting plates of the first U-shaped auxiliary keel 2 and the second U-shaped auxiliary keel 3 and the main keel 1, and the through holes 15 are elongated along the length direction of the keel. Figure 2 As shown, the perforations 15 are arranged obliquely on the plate body. The sound insulation holes 14 and the perforations 15 can play a role in reducing the sound conduction of the sound insulation keel, further improving the sound insulation effect of the partition wall. The plate bodies at both ends of the supporting parts 11 on both sides of the main keel 1 are respectively bent integrally to form two reinforcing ribs 17. In addition, the main keel 1 is also spaced apart on the plate body on both sides of the inclined surface 13 with a plurality of threading holes (not shown in the figure). Example 2
[0032] like Figure 3 or Figure 4 As shown, the utility model patent designs a second embodiment of a three-cavity partition wall keel. The difference between the three-cavity partition wall keel in this embodiment and embodiment 1 lies in the structure of the main keel 1. The bending parts of the main keel 1 located on both sides of the top of the wing plate of the second U-shaped sub-bone 3 are smooth arc-shaped bends 16. Figure 3 and Figure 4 The only difference is that the elongation direction of the perforation 15 is different. Figure 3 The middle through hole 15 is elongated along the length direction of the keel. Figure 4 The middle through hole 15 is arranged in an oblique direction. Example 3
[0033] like Figure 5 As shown, the utility model patent designs a third embodiment of a three-cavity partition wall keel. The difference between the three-cavity partition wall keel in this embodiment and embodiments 1 and 2 lies in the structure of the main keel 1. The main keel 1 is C-shaped or U-shaped, and the first U-shaped sub-keel 2 and the second U-shaped sub-keel 3 are respectively connected to both sides of the middle part of the main keel 1. Example 4
[0034] like Figure 6 or Figure 7 As shown, the utility model patent designs a partition wall keel support structure, which includes top and bottom keels 4 installed on the roof and the ground respectively. The top and bottom keels 4 are U-shaped grooves, and a number of connection holes 41 are evenly distributed on the bottom plate and the side plates thereof. A number of three-cavity sound insulation keels as described in the above embodiment are evenly arranged and fixed between the top and bottom keels 4 on the roof and the ground. Figure 6 and Figure 7 The only difference between the top and bottom keels is the position of the openings on the base plate.
[0035] When the three-chamber partition keel disclosed in this embodiment is used, first lay the top and bottom keels 4 on the roof and the ground respectively according to the location of the partition wall, and then arrange a number of partition wall keels evenly, and the upper and lower ends of the partition wall keel are respectively connected and fixed with the top and bottom keels 4 on the roof and the ground by rivets to form the keel support structure of the partition wall, and then start to install the partition wall panels. During installation, first install the two layers of partition wall panels at the middle connection part of the partition wall keel, and then install the partition wall panels on the supporting parts on both sides of the partition wall keel. When installing the partition wall panels at the middle connection part, first insert one end of the partition wall panel into the U-shaped partition board connection position 31 of the previous partition wall keel, and then lean the other end of the partition wall panel on the L-shaped partition board connection position 21 of the next partition wall keel, and use rivets or nails to respectively connect and fix the two ends of the partition wall panel with the partition wall keels on both sides. The entire operation process can be completed by a single person, with high installation efficiency and low labor cost.
