Abstract

This invention discloses a structural column structure and construction method integrated with a lightweight interior partition wall. The structure includes a first lightweight partition wall panel and a channel steel structural column. The channel steel structural column is integrally formed with the first lightweight partition wall panel, so that the inner side of the channel of the channel steel structural column is tightly connected to the first lightweight partition wall panel. The cross-sectional height of the channel steel structural column is less than the thickness of the first lightweight partition wall panel, so that there is a gap between the outer side of the upper and lower flanges of the channel steel structural column and the surface of the first lightweight partition wall panel. Compared with the traditional hollow box-shaped steel structural column, the sound insulation performance of the structure can be improved; and the cross-section of the channel steel is smaller than that of the box steel, which can save steel costs. The gap between the outer side of the upper and lower flanges of the channel steel structural column and the surface of the first lightweight partition wall panel provides space for the structural column to be plastered with wire mesh, avoiding affecting the net width of the room.

Figure 4 As shown, its connection is simple and easy to decorate, but its steel cost is high and its sound insulation effect is poor.

[0029] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0031] like Figure 1 and Figure 3As shown, this invention discloses a structural column structure integrated with a lightweight interior partition wall, which can be used in prefabricated steel structure buildings. The structure includes a first lightweight partition wall panel and a channel-shaped steel structural column. The channel-shaped steel structural column is integrally formed with the first lightweight partition wall panel, so that the inner side of the channel of the channel-shaped steel structural column is tightly connected to the first lightweight partition wall panel. The cross-sectional height of the channel-shaped steel structural column is less than the thickness of the first lightweight partition wall panel, so that there is a gap between the outer side of the upper and lower flanges of the channel-shaped steel structural column and the surface of the first lightweight partition wall panel.

[0032] In this embodiment, the channel steel structural column includes a web and upper and lower flanges respectively connected to both ends of the web. The first lightweight partition wall is an autoclaved aerated concrete panel. The first lightweight partition wall is prefabricated in the factory and then transported to the construction site for installation. During the installation of the first lightweight partition wall, the channel steel structural column can be placed into the template of the first lightweight partition wall. After the concrete of the first lightweight partition wall is poured and hardened, the first lightweight partition wall and the channel steel structural column become an integrated structure during prefabrication. The slot of the channel steel structural column is oriented towards the first lightweight partition wall so that the inner side of the slot of the channel steel structural column is tightly connected to the first lightweight partition wall. The inner side of the slot is the inner side of the upper flange, the web, and the lower flange. Taking a 200mm thick lightweight partition wall as an example, the channel steel structural column uses 16a channel steel, with a steel consumption of approximately 17.23 kg / m. In contrast, a traditional box-type steel structural column, with a cross-sectional dimension of 200mm × 200mm × 10mm, consumes approximately 59.66 kg / m of steel. This invention reduces steel costs by approximately 70% per meter, significantly improving upon the problem of excessive steel consumption in traditional box-type steel structural columns. Furthermore, the outer surfaces of the upper and lower flanges of the channel steel structural column are spaced from the surface of the first lightweight partition wall. This space provides room for applying plaster and mesh, preventing the plaster and mesh from protruding from the wall surface and affecting the interior width, as is the case with traditional box-type steel structural columns. Moreover, compared to the hollow interior of traditional box-type steel structural columns, the inner surface of the channel opening of this invention is tightly connected to the first lightweight partition wall, improving the structure's sound insulation performance.

[0033] In some embodiments, the inner side of the groove of the channel steel structural column is provided with beard-shaped ribs.

[0034] In this embodiment, during the prefabrication of the first lightweight partition wall panel and the channel steel structural column, before pouring the first lightweight partition wall panel, a rib (not shown in the figure) is set on the inner side of the channel of the channel steel structural column. The rib can be fixed to the inner side of the channel of the channel steel structural column by welding and extends towards the preset position of the first lightweight partition wall panel. This improves the bonding between the channel steel structural column and the first lightweight partition wall panel after the concrete of the first lightweight partition wall panel hardens, thereby improving the overall strength of the structure.

[0035] See also Figure 2 In some embodiments, the structure further includes a second lightweight partition wall with the same thickness as the first lightweight partition wall, the second lightweight partition wall being connected to the outer side of the web of the channel steel structural column by an adhesive material.

[0036] In this embodiment, the prefabricated first lightweight partition wall panel and the channel steel structural column are connected to the second lightweight partition wall panel on the construction site to form a partition wall structure that meets the design length requirements. The second lightweight partition wall panel is also a prefabricated autoclaved aerated concrete panel, with the same thickness and material as the first lightweight partition wall panel. The second lightweight partition wall panel is connected to the outer side of the web of the channel steel structural column using an adhesive material, thereby connecting the first and second lightweight partition wall panels. Furthermore, there is a gap between the outer surfaces of the upper and lower flanges of the channel steel structural column and the surface of the second lightweight partition wall panel.

[0037] In some embodiments, the outer sides of the upper and lower flanges of the channel steel structural column are provided with a wire mesh plaster layer.

[0038] In this embodiment, a wire mesh plastering layer is provided on the outer side of the upper and lower flanges of the channel steel structural column. That is, the wire mesh plastering is applied to the outer side of the upper and lower flanges. Since there is a gap between the outer surface of the upper and lower flanges of the channel steel structural column and the surface of the first and second lightweight partition walls, the wire mesh plastering is applied between this gap. Taking the first lightweight partition wall as 200mm thick as an example, the channel steel structural column is made of 16a channel steel, and the thickness of the wire mesh plastering layer on the outer surface of the upper or lower flange is 20mm. It just fills the gap between the outer surface of the upper and lower flanges and the surface of the first and second lightweight partition walls, without affecting the net width of the room. The wire mesh and plaster layer is used to treat the surface of the channel steel structural column to facilitate subsequent wall decoration construction. The wire mesh can be made of 20mm×20mm×4mm steel bars, which are spot-welded to the outer side of the upper and lower flanges. The diameter of the steel bars is not less than 0.6mm. Then, ordinary cement mortar of grade M5 is used for plastering.

[0039] In some embodiments, to ensure the aesthetics of the wall surface, a structural column decorative surface layer is provided on the wire mesh plaster layer, and wall panel decorative surface layers are provided on both sides of the first lightweight partition wall and the second lightweight partition wall. The outer surface of the structural column decorative surface layer is flush with the outer surface of the wall panel decorative surface layer, and the structural column decorative surface layer and the wall panel decorative surface layer adopt the same construction method.

[0040] In some embodiments, the decorative surface layer of the structural column and the decorative surface layer of the wall panel include a putty layer and a paint layer.

[0041] In some embodiments, the decorative finish on structural columns and wall panels includes a ceramic tile layer.

[0042] In some embodiments, the adhesive material includes a polyester foaming agent, a polyethylene rod, and a sealant.

[0043] In this embodiment, the adhesive material is used to connect the second partition wall panel and the web of the channel steel structural column, and to fill the gap between the second partition wall panel and the web of the channel steel structural column. The polyester foaming agent is an environmentally friendly material that can effectively improve the sound insulation effect of the structural column structure integrated with the lightweight interior partition wall; the polyethylene rod can effectively improve the thermal insulation performance of the structure, thereby improving the energy-saving effect of the building using this structure. The caulking agent can effectively seal the gap between the second partition wall panel and the channel steel structural column, improving the overall integrity of the structure.

[0044] In some embodiments, the first lightweight partition wall panel includes a first panel and a second panel disposed opposite to each other, and the distance between the outer side of the upper flange of the channel steel structural column and the first panel of the first lightweight partition wall panel is equal to the distance between the outer side of the lower flange of the channel steel structural column and the second panel of the first lightweight partition wall panel.

[0045] In this embodiment, taking a first lightweight partition wall panel with a thickness of 200mm as an example, the channel steel structural column is selected from channel steel of model 16a, with a web height of 160mm. The distance between the outer side of the upper flange and the first surface of the first lightweight partition wall panel is 20mm, and the distance between the outer side of the lower flange and the second surface of the first lightweight partition wall panel is 20mm. That is, the central axis of the web is on the same straight line as the center line of the thickness direction of the first lightweight partition wall panel, so as to ensure the uniformity of force transmission between the first lightweight partition wall panel and the channel steel structural column and improve the strength of the structure.

[0046] The structural column structure integrated with a lightweight interior partition wall disclosed in this invention includes a first lightweight partition wall panel and a channel steel structural column. The channel steel structural column is integrally formed with the first lightweight partition wall panel, so that the inner side of the channel of the channel steel structural column is tightly connected to the first lightweight partition wall panel. The cross-sectional height of the channel steel structural column is less than the thickness of the first lightweight partition wall panel, so that there is a gap between the outer side of the upper and lower flanges of the channel steel structural column and the surface of the first lightweight partition wall panel. (Comparatively...) Figure 4 The structural column structure integrated with lightweight interior partition walls disclosed in this invention has at least the following beneficial effects:

[0047] Significantly improves the problem of excessive steel consumption in traditional box-type steel structural columns;

[0048] It improves the problems of poor sound insulation of traditional box-type steel structural columns and the adverse effects of wire mesh and grouting on indoor usable space;

[0049] In this embodiment of the invention, the standard channel steel structural column is prefabricated in an integrated manner with the first lightweight partition wall panel in the factory, which can greatly simplify the secondary construction process and time of the structural column on site and improve the efficiency of on-site construction.

[0050] Reduce the amount of on-site wet work for cast-in-place concrete structural columns.

[0051] This invention also discloses a construction method for constructing the structural column structure integrated with the lightweight interior partition wall as described in the above embodiments, the method comprising:

[0052] Step 1: When prefabricating the first lightweight partition wall panel, the channel steel structural column is integrally formed with the first lightweight partition wall panel.

[0053] When constructing the first lightweight partition wall panel, the channel steel structural column can be placed inside the formwork of the first lightweight partition wall panel, or the channel steel structural column can be tightly spliced ​​with the formwork of the first lightweight partition wall panel, making the channel steel structural column one end of the formwork. After the concrete of the first lightweight partition wall panel is poured and hardened, the first lightweight partition wall panel and the channel steel structural column are integrated into a single structure during prefabrication. Specifically, the groove of the channel steel structural column is positioned facing the first lightweight partition wall panel, so that the inner side of the groove of the channel steel structural column is tightly connected to the first lightweight partition wall panel.

[0054] Step 2: On-site installation of the second lightweight partition wall panel and the integrally formed channel steel structural column with the first lightweight partition wall panel.

[0055] On the construction site, such as on the floor, lines are laid out to determine the specific positions of the second lightweight partition wall panel and the integrally formed channel steel structural column and the first lightweight partition wall panel on the floor. The second lightweight partition wall panel, the integrally formed channel steel structural column and the first lightweight partition wall panel are hoisted to the determined positions and corresponding support treatment is provided. Adhesive material is used to fill the gaps between the second lightweight partition wall panel and the channel steel structural column so that the second lightweight partition wall panel, the integrally formed channel steel structural column and the first lightweight partition wall panel form an integral wall structure.

[0056] Step 3: Perform facade construction on the second lightweight partition wall panel, the channel steel structural column, and the first lightweight partition wall panel.

[0057] Facade construction includes the application of wire mesh and plaster layers, putty and paint layers, and tile layers.

[0058] Understandably, facade construction may also include the construction of insulation layers, sound insulation layers, etc.

[0059] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
