Description

Technical Field

[0001] The utility model belongs to the field of partition walls, in particular to an assembled partition wall structure. Background Art

[0002] Partition walls can flexibly divide space and create free space.

[0003] Partition panels are an important part of industrial buildings, and most traditional buildings use on-site masonry construction.

[0004] Traditional masonry partition walls have the disadvantages of being relatively heavy, requiring a lot of masonry work, and requiring a lot of steel bars, and will gradually fade out of the historical stage. With the gradual development of modern architecture, prefabricated lightweight partition panels have played an increasingly important role, but they have many joints, are prone to shrinkage and deformation, are easy to break, cannot be pre-buried for water and electricity, require a lot of excavation in the later stage, and are prone to disturbance of the wall panels, and other issues need to be urgently addressed.

[0005] In order to avoid the problems of traditional partition wall methods and promote the low-carbon green transformation of the construction industry, people invented prefabricated partition wall structures.

[0006] At present, most of the interior partition walls of buildings in my country are masonry partition walls + plastering + putty + paint.

[0007] The construction of the space (gap) between the infill wall and the load-bearing main structure should be carried out 14 days after the infill wall is built.

[0008] After the top masonry is completed, plastering work is carried out. The overall construction time is relatively long, and the construction process generates a lot of noise and dust pollution, which is extremely detrimental to the physical and mental health of the workers.

[0009] The construction process of masonry partition walls using this technology is complicated, requires many professional workers, consumes a lot of resources, and causes a lot of pollution during the construction process, which is not in line with the green development trend of the engineering construction industry.

[0010] In summary, the existing partition wall structures have certain drawbacks when in use and do not meet people's usage requirements. For this reason, we propose an assembled partition wall structure. Summary of the invention

[0011] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides an assembled partition wall structure. By adjusting the structure of the indoor partition wall and adopting a keel combined with a wall panel structure, the fully assembled construction of the indoor partition wall can be realized, and the total thickness of the partition wall structure can be reduced. The wall panel can use 3D printing technology and coating technology to achieve rich finishing styles. By setting a PE film air barrier layer, the diffusion of rock wool flying chips inside the partition wall is blocked, and the sound insulation and airtightness of the partition wall can be improved. Moreover, all wall panel components are factory-processed to a fixed length and can be quickly assembled and constructed on site, with high installation efficiency. Compared with traditional partition walls, this structure can increase the actual indoor use area, indoor living quality and waterproof effect of water-filled rooms, has great promotion value, and has good prospects for use.

[0071] The distance between two adjacent groups of vertical keels 13 is less than or equal to 600 mm, and the thickness of the assembled partition wall structure is 90 mm, which is about 35% less than the thickness of the traditional partition wall, thereby increasing the actual usable area.

[0072] Embodiment 4:

[0073] On the basis of Example 3, Figure 1-Figure 4 As shown, this embodiment shows the structure of the transverse keel 14 .

[0074] A plurality of groups of connection seats 141 are fixedly installed at equal intervals on the inner side of the opening of the transverse keel 14 , and the plurality of groups of connection seats 141 on the two groups of transverse keels 14 are connected by support members.

[0078] The support rod 143 is inserted into the connecting sleeve 142 .

[0079] Working principle: When in use, first install the top keel 11 and the ground keel 12;

[0080] Expansion bolts are used to fix the top purlin 11 and the ground purlin 12. The spacing between the fixing points is less than 600 mm, and the end is no larger than 50 mm. The purlins can be fixed with nails on the concrete base.

[0081] Install vertical keel 13

[0082] Position the vertical keels 13 according to the spacing determined by the design. The center spacing of the vertical keels 13 should not be greater than 600mm. Arrange the vertical keels 13 from one end of the partition wall, and arrange them from the door and window openings to both sides of the wall with doors and windows. When the distance between the last vertical keel 13 and the wall (column) is greater than the design requirement, an additional vertical keel 13 must be added.

[0083] Push the vertical keel 13 between the top keel 11 and the ground keel 12, with the flange facing the cover panel. The upper and lower ends of the vertical keel 13 are fixed to the top keel 11 and the ground keel 12 with rivets. Before fixing, the vertical keel 13 must be adjusted vertically (except for special shapes).

[0084] The main keel at the door and window openings shall be installed in accordance with the design requirements, using a double-root embracing installation method or adding another vertical keel 13 to serve as a reinforced keel.

[0085] Install transverse keel 14

[0086] When the height of the partition frame exceeds 3m, or the horizontal board end (joint) of the cover panel does not fall on the top keel 11 and the ground keel 12, a transverse keel 14 should be installed. Select U-shaped keels for transverse arrangement, first use a pistol drill to drill holes, and then fix them with vertical keels 13 with rivets.

[0087] After fixing the transverse keel 14 in one direction, the transverse keel 14 in the other direction is installed directly opposite to the installed transverse keel 14, so that the support rod 143 is inserted into the connecting sleeve 142 to achieve preliminary positioning of the transverse keel 14, and then fixed to the vertical keel 13 with rivets.

[0088] Installation of pipelines and equipment

[0089] Organize on-site pipeline layout and installation according to the mechanical and electrical pipeline positions optimized by BIM, and fix the junction boxes and various equipment.

[0090] Filling sound insulation and flame retardant materials

[0091] When thermal insulation or sound insulation materials are designed, they should be laid according to the design requirements. The rock wool board filling material in the wall should be fixed and protected from moisture. When installing, try to install it at the same time as the other side panel. The filling material should be fully laid flat to form a sound insulation and flame retardant layer 2.

[0092] Air barrier construction

[0093] According to the wall size, the PE film is cut and fixed on the keel with nails and 40×40×2mm rubber gaskets. The spacing between the fixing points around the partition wall is 300mm. The PE film at the wall wire box and other locations is cut diagonally along the wire box, and transparent glue is used to stick around the wire box to prevent the rock wool flying chips from overflowing, forming the PE film air barrier layer 3.

[0094] Install wall panels 4

[0095] The wall panels 4 must be laid flat on the work surface, and each wall panel 4 is numbered. Before assembly, the overlap relationship and installation order must be determined according to the drawings. For walls with doors and windows, the panels are arranged from the door and window positions to both sides. After the panels are determined, the first panel is prepared and placed in place according to the ink line position. Before assembly, the back of the panel and the surface of the keel must be dry-erased. A structural glue gun is prepared with a glue outlet diameter of about 10 mm. Then, glue points are applied on the surface of the horizontal keel 14. The location of the glue application points is no less than 5 glue points on each panel longitudinally. Then, the panels are glued in sequence, and the I-shaped aluminum profiles are inserted at the panel seams and firmly nailed to the keel to ensure that the height difference of the joints is less than 0.5 mm. The wall panels 4 are closely spliced ​​with herringbone overlap at the internal corners. If the structural deviation causes the wall panels 4 to be cut twice, the panel edges are processed straight and smooth with a trimmer after rough cutting without burrs.

[0096] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
