Description

Technical Field

[0001] This utility model relates to wall construction, and in particular to an exterior wall structural column structure that can be quickly installed and its application in building structures. Background Technology

[0002] Building facades often have vertical lines. If prefabricated construction is not used, most buildings use structural columns at both ends and masonry in the middle. However, construction workers are gradually decreasing and labor costs are increasing. If the external structural columns are made of masonry, external supports are required, which is costly. For high-rise buildings of 100 meters, scaffolding needs to be erected for convenient construction. The masonry cost is expensive and the construction is also more dangerous.

[0003] Generally, structural columns require pre-installed reinforcing bars or bolts at their bottom and top for connection to the main structure. Most existing products use grouting sleeves for this connection. As shown in the diagram, an existing office building's outer ring structural columns consist of a 750mm long exterior wall masonry section composed of two 200x200 concrete structural columns, with masonry in the middle. This section of masonry is typically constructed manually on-site, requiring the initial masonry work (often lacking toothed joints) before formwork is erected to cast the 200x200 structural columns. In this era of soaring labor costs, traditional methods are increasingly expensive, using numerous formworks and failing to achieve green, low-carbon, and energy-saving practices. Furthermore, this connection method presents limitations during installation. For example, using sleeves to connect reinforcing bars requires pre-installing the structural columns, then constructing the next layer of beams and slabs, and finally, after the upper beams and slabs are completed, constructing the next layer of structural columns, and so on, making continuous construction inconvenient and restricting the construction sequence. If the main structure is built first and the structural columns are installed later, the installation process requires aligning the pre-drilled holes at the bottom of the structural columns vertically with the pre-reserved steel bars. However, the already constructed upper floor slabs will affect the hoisting of the structural columns, requiring construction layer by layer, which is inconvenient for installation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and provide a quickly installable exterior wall structural column structure and its application in building construction. Based on prefabricated construction principles, it is first manufactured in a factory and then installed on-site. The structural column is installed onto the main structure like a component, and a novel connection method is creatively designed. Therefore, using this invention allows for easier assembly line operations and simultaneous construction on multiple work surfaces.

[0005] This utility model provides a quick-installable exterior wall structural column structure, including a structural floor slab and an exterior wall. The exterior wall includes a plurality of parallel exterior wall structural columns located between two adjacent structural floor slabs and arranged circumferentially along the structural floor slabs. Each exterior wall structural column is an integrally formed structure.

[0006] In the above technical solution, the exterior wall structural column has a plate structure on the side facing the outside. Each exterior wall structural column has vertical stiffening strips protruding from the interior side on both sides. Each exterior wall structural column has protrusions at the top and bottom of the interior side. The protrusions are located between the stiffening strips on both sides. The protrusions and stiffening strips together enclose a cavity that serves as an insulation layer.

[0007] In the above technical solution, each exterior wall structural column has longitudinally and transversely arranged ribs inside the cavity on the interior side.

[0008] In the above technical solution, the two ends of the vertically arranged ribs of each external wall structural column are connected to the top and bottom protrusions respectively. The connection between each vertically arranged rib and the connected protrusion, as well as the connection between each stiffening strip and the connected protrusion, forms a horizontal T-shaped structure. The two ends of the horizontally arranged ribs of each external wall structural column are connected to the stiffening strips respectively.

[0009] In the above technical solution, the top and bottom protrusions of the external wall structural column are provided with multiple vertical pin hole slots. The multiple pin hole slots are arranged at intervals with the ribs and stiffening strips. Each pin hole slot is provided with a bolt or pre-embedded steel bar that passes through the structural floor slab and connects to the corresponding external wall structural column of the lower or upper layer.

[0010] In the above technical solution, a cover plate is provided between the stiffening strip of each external wall structural column and the vertically arranged rib plate, and between the vertically arranged rib plates respectively.

[0011] In the above technical solution, an operating groove is provided between the end of the cover plate and the corresponding protrusion to separate the cover plate from the protrusion.

[0012] In the above technical solution, a flexible sealing layer is provided between the top and bottom of each external wall structural column and the adjacent structural floor slab.

[0013] This utility model also provides a building structure with a quick-installable external wall structural column structure. Each floor slab has two rings of steel beams arranged circumferentially at its bottom, and multiple diagonal supports are evenly distributed circumferentially between the two rings of steel beams.

[0014] This utility model provides a quick-installation external wall structural column structure and its application in building structures, offering the following advantages:

[0015] Compared with existing technologies, this invention not only facilitates installation, but also allows for all installation work to be carried out indoors, eliminating the need for external scaffolding. This structural column can be installed from the side via hoisting. Furthermore, the installation of this type of structural column does not interfere with the main structure construction process; it can be carried out after the building reaches a sufficient height, and all construction can be conducted indoors.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0023] Figure 1 The outer structural columns of the existing office building shown have been described in detail in the background section and will not be repeated here.

[0024] See Figures 2 to 4 This utility model discloses a quick-installable exterior wall structural column structure, comprising a structural floor slab 1 and an exterior wall. The exterior wall includes multiple parallel exterior wall structural columns 2 located between two adjacent structural floor slabs 1 and arranged circumferentially along the structural floor slab 1. Each exterior wall structural column 2 is an integrally formed structure. The components of this utility model are non-load-bearing components in the structure; conventional structural reinforcement is sufficient to meet the load-bearing requirements. During hoisting, reinforcement can be carried out separately for the hoisting conditions. 5mm diameter steel bars are used to form a steel mesh, which is then poured into C30 grade concrete.

[0025] See Figure 5 Each exterior wall structural column 2 has a panel structure on its exterior-facing side. On both sides of the interior-facing side of each exterior wall structural column 2, vertical stiffening strips 21 protrude from the interior side. At the top and bottom of the interior side of each exterior wall structural column 2, protrusions 22 are provided, all located between the stiffening strips 21 on both sides. The protrusions 22 and the stiffening strips 21 together enclose a cavity that serves as an insulation layer. A structural model was built using Rhino.

[0026] Each exterior wall structural column 2 has longitudinally and transversely arranged ribs 23 within its interior cavity. The vertically arranged ribs 23 of each exterior wall structural column 2 are connected at both ends to top and bottom protrusions 22, respectively. The connection points between each vertically arranged rib 23 and its connecting protrusion 22, as well as between each stiffening strip 21 and its connecting protrusion 22, form a horizontal T-shaped structure. The horizontally arranged ribs 23 of each exterior wall structural column 2 are connected at both ends to stiffening strips 21. The ribs 23 are made of steel fiber reinforced concrete, or UHPC concrete can be used to make the structural column thinner, but the basic method remains the same: weight reduction design in the middle section, treating the structural column as a whole. Of course, other connection methods can also be used, but the core principle is to create installation notches on the side.

[0027] The top and bottom protrusions 22 of the external wall structural column 2 are respectively provided with multiple vertical pinhole slots 24. These pinhole slots 24 are arranged at intervals with the ribs 23 and stiffening strips 21. Each pinhole slot 24 is provided with a bolt 3 that passes through the structural floor slab 1 and connects to the corresponding external wall structural column 2 on the lower or upper floor. Stress calculations require verification of the reinforcement under local wind pressure and the shear bearing capacity of the bolts 3. Generally, 25mm diameter steel bars are sufficient for the needs of typical building heights.

[0028] See Figure 6 Each external wall structural column 2 has a cover plate 25 between its stiffening strip 21 and the vertically arranged ribs 23, and between the vertically arranged ribs 23. A polystyrene board is used as an inner template between the upper and lower cover plates 25 to form a cavity, which provides insulation. The cover plate 25 on the indoor side may be omitted; instead, insulation material is filled within the lattice structure and sealed with gypsum board or other decorative panels. This structural column is manufactured in the factory, transported to the construction site, and installed.

[0029] An operating groove 26 is provided between the end of the cover plate 25 and the corresponding protrusion 22 to separate the cover plate 25 and the protrusion 22.

[0030] See Figures 2 to 3 Each external wall structural column 2 has a flexible sealing layer 4 between its top and bottom and the adjacent structural floor slab 1.

[0031] Of course, for small spans, only rectangular stiffening ribs can be set, instead of using T-shaped stiffening ribs composed of stiffening strips 21, protrusions 22 and rib plates 23.

[0032] See Figure 2 This utility model applies to a building with an external wall structural column structure that can be installed quickly. Each floor slab 1 has two rings of steel beams 5 arranged circumferentially at the bottom. Multiple diagonal supports 6 are evenly distributed circumferentially between the two rings of steel beams 5.

[0033] After installation, the pin hole groove 24 is sealed with micro-expansion concrete and smoothed. In this way, the durability of the structural column and the fire resistance of the bolts are protected by concrete, meeting the requirements of the specifications.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
