Description

Technical Field

[0001] This utility model relates to a structural column structure for connecting wall panels. Background Technology

[0002] In multi-story frame structures, non-load-bearing partition walls often use wall panels as partition walls. These partition walls typically have structural columns, which are usually not poured together with the main concrete structure but are installed after the main building construction is completed. Traditional cast-in-place concrete structural columns have formwork at the top that prevents vibrators from being inserted, requiring vibration only from outside the formwork, resulting in an incomplete compaction of the top 200mm of concrete. Precast structural columns also present some problems. For example, Chinese patent CN 220620714U discloses a lightweight partition wall panel precast structural column. In this patent document, the structural column is precast, with its top and bottom ends connected to the bottom and top floor slabs respectively using high-strength expansion bolts. Lightweight partition walls are installed on both sides of the precast structural column. In this technical solution, due to settlement and construction accuracy considerations, the length of the structural column does not perfectly match on the construction site. When the precast structural column is too long, installation becomes difficult; when it is too short, gaps exist at the top of the column. Utility Model Content

[0003] The purpose of this invention is to solve the problem of length error in precast structural columns during construction. By setting the structural columns as a first column and a second column, the relative adjustment of the first column and the second column can be used to adapt to settlement or construction errors.

[0004] Therefore, this utility model provides a structural column structure for connecting wall panels, including wall panels and precast structural columns. The wall panels are connected to the precast structural columns. Each precast structural column includes a first column body, a second column body, and a fixing part. The upper end of the first column body is connected to a top plate, and the lower end of the second column body is connected to a bottom plate. The distance between the upper end of the first column body and the lower end of the second column body is adjustable. The fixing part is used to fix the first column body and the second column body.

[0005] Furthermore, the first column and the second column are channel steel, the second column has an inner cavity, and the first column is inserted into the inner cavity of the second column to achieve relative movement of the first column and the second column, so as to adjust the length of the structural column to match the height between the top plate and the bottom plate.

[0006] Furthermore, a first connecting plate is fixed to the upper end of the first column, and the connecting plate is connected to the top plate with bolts. A second connecting plate is fixed to the lower end of the second column, and the second connecting plate is connected to the bottom plate with bolts.

[0007] Furthermore, the second column is provided with grouting holes. After the first and second columns are connected to the top plate and the bottom plate, grout is injected into the inner cavity of the second column through the grouting holes to form a fixing part.

[0008] The fixing part is a U-shaped channel steel pad between the upper end of the second column and the first connecting plate; the through hole in the pad is vertically arranged and the first column passes through the through hole, so that the upper and lower ends of the pad are supported between the upper ends of the first connecting plate and the second column; or the through hole in the pad is horizontally arranged and the pad is arranged on both sides of the first column, and the upper and lower walls of the pad are fixed to the upper end surfaces of the first connecting plate and the second connecting column with bolts.

[0009] Furthermore, the shape of the second connecting plate is the same as the cross-sectional shape of the second column, and part of the side wall of the second column is fixed to the second connecting plate. The lower end of the side wall of the second column is provided with an installation window for installing bolts on the connecting plate.

[0010] Furthermore, the second column and the wall panel have a groove on one side, and the other side of the wall panel has a protrusion that mates with the groove of the adjacent wall panel or the second column. The protrusion and the groove are connected by an adhesive, mortar or connector.

[0011] Furthermore, it also includes U-shaped slots provided on the bottom plate and the top plate, with the upper and lower ends of the wall panel respectively installed in the U-shaped slots on the top plate and the bottom plate.

[0012] The pad can also be connected to both ends of the U-shaped slot used for installing the wall panel.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] This utility model discloses a prefabricated structural column structure for connecting wall panels. The prefabricated structural column includes a first column and a second column, which are movable relative to each other to adjust the length of the structural column so that it matches the construction site. In a specific embodiment of this utility model, a fixing block is used to fix the first column and the second column. This fixing method includes placing a pad between the first connecting plate at the upper end of the first column and the upper end of the second column, or placing a support block between the bottom of the first column and the second connecting plate of the second column, or grouting in the inner cavity of the second column for fixing.

[0023] Reference Figures 1 to 6As shown, the present invention discloses a structural column structure for connecting wall panels, comprising a wall panel 2 and a precast structural column 1. The wall panel 2 is connected to the precast structural column 1. The precast structural column 1 includes a first column body 101, a second column body 102, and a fixing part. The upper end of the first column body 101 is connected to a top plate 12, and the lower end of the second column body 102 is connected to a bottom plate 13. The distance between the upper end of the first column body 101 and the lower end of the second column body 102 is adjustable. The fixing part is used to fix the first column body 101 and the second column body 102. The wall panel 2 can be a prefabricated wall panel. Several wall panels 2 are assembled to form a partition wall 4. Structural columns 1 are set at both ends of the partition wall 4. The prefabricated structural columns 1 can be channel steel. The first column 101 and the second column 102 are both channel steel. The second column 102 has an inner cavity 103. The first column 101 can be inserted into the inner cavity 103 of the second column. The upper end of the first column 101 and the lower end of the second column 102 are respectively connected to the first connecting plate 9 and the second connecting plate 10. Holes are set on the first connecting plate 9 and the second connecting plate 10, and they are fixed to the embedded parts of the top plate 12 or the bottom plate 13 with bolts. During construction, the first column 101 and the second column 102 are combined. The first connecting plate 9 on the first column is fixed to the top plate 12 with bolts, and the second connecting plate 10 of the second column is fixed to the bottom plate 13 with bolts. A grouting hole can be pre-set at the lower end of the second column 102 to inject grout into the inner cavity 103, forming a concrete fixing part to fix the first column 101 and the second column 102. The distance between the two structural columns 1 is equal to the combined length of several wall panels 2. U-shaped slots 3 can be provided on the top plate 12 and the bottom plate 13 for installing the wall panels 2. A crossbeam can also be installed between the two structural columns 1, and the wall panels 2 are fixed to the crossbeam. (Refer to...) Figure 6 As shown, grooves 6 are provided on the two sides opposite to the structural column 1 and the wall panel 2. A protrusion 7 is provided on one side of the wall panel 2 and a groove 6 is provided on the other side. The protrusion 7 of the wall panel cooperates with the groove 6 of the adjacent structural column or wall panel.

[0024] Figure 2 The image shows Embodiment 2 of the fixing part, see reference. Figure 3 As shown, the fixing part is a U-shaped channel steel pad 5 located between the upper end of the second column 102 and the first connecting plate 9. The pad 5 has a through hole 14, which is vertically oriented. The first column 101 passes through the through hole 14. The upper and lower ends of the pad 5 are respectively supported by the upper ends of the first connecting plate 9 and the second column 102. The upper and lower ends of the pad 5 can be connected to the first connecting plate 9 or the second column 102 by welding. During construction, the upper end of the pad 5 or the second column 102 can be flexibly cut off on-site to match the overall length of the structural column 1 with the floor height.

[0025] In embodiment 2, the through hole 14 in the pad 5 can also be arranged horizontally. The first column 101 no longer passes through the through hole; instead, the pad 5 is placed on both sides of the first column 101. The upper and lower walls of the pad 5 are fixed to the upper end surfaces of the first connecting plate 9 and the second column, respectively, with bolts. In this embodiment, the upper end of the second column 102 can be cut off for adjusting its length during construction. (Refer to...) Figure 4 As shown, the pad 5 can also be integrally formed with or connected to the U-shaped slot 3. Each end of the U-shaped slot 3 is connected to the pad 5. When the U-shaped slot 3 is connected to the pad 5 and the pad 5 is connected to the structural column 1, the number of bolts connecting the U-shaped slot 3 to the top plate 12 or the bottom plate can be appropriately reduced.
