Description

Technical Field

[0001] This utility model relates to the field of building structures, specifically to a decorative false column. Background Technology

[0002] The connection node of a decorative false column refers to the connection between the top of the false column and the bottom of the structural beam. This part bears the weight of the false column and the deformation of the structural beam, making it prone to stress concentration and cracking. A major influencing factor is the settlement of the false column foundation, i.e., the subsidence of the ground beneath the false column. This causes changes in the height of the false column, thus altering the position and angle of the connection node, leading to increased stress and cracking. Cracks in the connection node affect the integrity and aesthetics of the false column, causing cracks and gaps on its surface, thus ruining its decorative effect and style. Simultaneously, cracks in the connection node also affect the stability and safety of the false column, causing the connection to loosen and detach, increasing the risk of collapse and the probability of accidents.

[0014] Figure 1 This is a structural schematic diagram of a decorative false column according to the present invention. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0017] Reference Figure 1 As shown, this utility model discloses a decorative false column. Specifically, the decorative false column includes a false column body 10, a concrete structural beam 20, and a connector 30. The false column body 10 is connected to the concrete structural beam 20 through the connector 30. The decorative false column also includes a false column composite structure foundation. The I-beams within the false column composite structure foundation are welded to the permanent temporary enclosure structure, connecting the entire false column structure to the enclosure structure of the entire building. This utilizes the friction of the abandoned enclosure structure to reduce the settlement of the false column structure, thereby reducing design costs.

[0018] A connector 30 is installed at the top of the dummy column body 10. The connector 30 allows the decorative dummy column to move with structural displacement, thus avoiding stress concentration and cracking at the connection nodes. Specifically, the connector 30 includes a sidewall steel plate 301 with four through holes 302. These through holes are oval-shaped, and bolts 303 are installed in them. The diameter of the bolt shank of the bolt 303 is smaller than the diameter of the oval hole. The bolts 303 pass through the oval holes and connect to the dummy column body 10. When the sidewall steel plate 301 is placed on the dummy column body 10, the connector 30 can move vertically, allowing the decorative dummy column to adapt to the deformation of the structural beam and reducing the risk of cracking in the concrete structural beam 20. Furthermore, an I-beam is installed within the concrete foundation of the dummy column, and the I-beam is welded to the permanent temporary enclosure.

[0019] Cement pressure plates 40 are provided on both sides of the false column body 10. The false column body 10 and the cement pressure plates 40 are connected by square tubes. One side of the square tube is welded to the side wall of the false column body 10, and the other side of the square tube is fixedly connected to the cement pressure plate 40 by self-tapping screws passing through the cement pressure plate 40 and the other side of the square tube. Furthermore, exterior wall paint is applied to the outer wall of the cement pressure plate 40.

[0020] A top steel plate is also provided on the top of the dummy column body 10, and the top steel plate is welded to the top surface of the dummy column body 10. An expansion bolt is provided on the top steel plate, with one end fixed to the top of the dummy column body 10 and the other end passing through the top steel plate of the dummy column body 10 and connecting to the concrete structural beam 30. A screw hole is provided in the concrete structural beam 30 so that the screw portion of the expansion bolt can enter the concrete structural beam 30, and the nut portion of the expansion bolt is provided on the concrete structural beam 30. Ultimately, one end of the expansion bolt is fixed to the top steel plate of the dummy column body 10, and the other end passes through the top steel plate of the dummy column body 10 and connects to the concrete structural beam 30.

[0021] A cement mortar plaster layer is applied to one side of the concrete structural beam 30, and exterior wall paint is applied to the outer wall of the cement mortar plaster layer. A cement pressure plate 40 is also installed on the other side of the concrete structural beam 30, and exterior wall paint is also applied to the outer wall of the cement pressure plate 40. The concrete structural beam 30 and the cement pressure plate 40 are connected by square tubing, and a steel plate 50 is also installed between the concrete structural beam 30 and the cement pressure plate 40. The steel plate 50 is fixed to the side wall of the concrete structural beam 30 using expansion bolts.

[0022] The steel plate 50 and the cement pressure plate 40 are connected by a square tube. One side of the square tube is welded to the steel plate 50, and the other side of the square tube is fixed with a self-tapping screw. The self-tapping screw passes through the cement pressure plate 40 and the square tube, thus fixing the cement pressure plate 40 to the square tube. Screw holes are provided on the side wall of the concrete structural beam 30, allowing the screw portion of the expansion bolt to enter the concrete structural beam 30. The nut portion of the expansion bolt is located on the steel plate 50, ultimately fixing one end of the expansion bolt to the side wall of the concrete structural beam 30, while the other end passes through the steel plate 50 and connects to the concrete structural beam 30.

[0023] This plan first involves measuring and positioning the decorative false column foundation on the mud surface. Following the established construction plan and positioning lines, excavation and retaining wall construction are carried out, and a concrete foundation layer is poured on the mud surface. Then, precise measurement and positioning of the decorative false column foundation are performed. Next, the entire I-beam-reinforced concrete composite foundation structure is placed on the bottom reinforcing bars, with protective layer spacers on the bottom reinforcing bars. The I-beam is then hoisted above the bottom reinforcing bars, and welding is performed between the I-beam and the existing retaining wall sheet piles. Welding is also required between the I-beam and the reserved upper steel structure connecting square tube (before welding the reserved upper steel structure connecting square tube, measurement, positioning, and verification of deviations from the existing structural beams are performed for fine-tuning to ensure the positioning deviation is within 3mm). On-site inspection of the welds is conducted. After the welds pass inspection, the remaining reinforcing bars are tied. Then, the lower half of the false column foundation is poured with reinforced concrete, and the upper half of the false column foundation is sealed with slabs and reinforced concrete the following day. After the concrete reaches sufficient strength, the slabs are removed and the relevant construction areas are backfilled. Then, precise measurements and layout are performed to verify the positioning of the pre-reserved upper steel structure connecting square tubes. Next, the sliding supports at the top of the dummy columns are installed according to the verified positioning lines. Following the hoisting plan for the decorative dummy column steel structure, the upper steel structure square tube column of the decorative dummy column is hoisted to the pre-reserved upper steel structure connecting square tube, and the square tube is welded after welding. After relevant weld inspections, the cement pressure plate 40 is fixed to the square tube with self-tapping screws. Finally, white SKK exterior wall paint system is applied to the cement pressure plate 40.

[0024] The ultra-high dummy columns in this scheme can effectively resist the influence of external wind force and foundation settlement, thus greatly reducing the risk of cracking at the connection node between the top of the dummy column and the structural beam.
