The present invention solves the problems of a long construction period and high construction costs caused by the connection of a curved exterior wall with multiple circular columns having different embedded depths of the columns.

Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a construction method of a joint structure in which a cylinder and a curved outer wall are connected. Background Art

[0002] With the rapid development of the construction industry, architectural shapes are becoming more and more complex. In building structures, curved exterior walls and columns are increasingly appearing in engineering practice. These columns connected to the curved exterior walls bring great difficulties and challenges to construction. During construction, special design of the column formwork is often required. However, the connection position and angle between each column and the curved exterior wall are different. The steel formwork designed independently for each column cannot be used in a reusable manner, resulting in a lot of waste, high costs, and a long construction period.

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0004] In order to overcome the defects of the existing technology, a construction method of a joint structure in which a column is connected to a curved outer wall is provided to solve the problems of the curved outer wall being connected to multiple columns and the columns being embedded to different depths, resulting in a long construction period and high construction cost.

[0005] To achieve the above object, a construction method for a joint structure in which a column and a curved outer wall are connected is provided, comprising the following steps:

[0006] Supporting a wall formwork at the construction position of the curved outer wall of the joint structure, and forming a notch in the wall formwork at the construction position of the column of the joint structure;

[0007] tying a cylindrical steel reinforcement structure at the construction position of the cylinder;

[0008] Installing a plurality of embedded vertical bars on opposite sides of the cylindrical steel bar structure exposed at the notch;

[0009] Horizontal bars are connected to the outside of the plurality of embedded vertical bars, and the two ends of the horizontal bars extend into the casting space of the curved outer wall connected to the two sides of the cylindrical steel bar structure. The embedded vertical bars, the horizontal bars, and the side of the cylindrical steel bar structure exposed at the notch form a triangular prism or a quadrangular prism deformed steel bar structure, and the length of the cross section of the quadrangular prism deformed steel bar structure is adapted to the outer diameter of the cylindrical steel bar structure.

[0010] Setting up a column formwork outside the deformed steel bar structure so that the column formwork and the wall formwork are closed to form a closed pouring space;

[0011] Concrete is poured in the closed pouring space, and the concrete is wrapped around the cylindrical steel bar structure and the deformed steel bar structure to consolidate and form the joint structure.

[0012] Furthermore, the curved outer walls connected on both sides of the cylindrical steel bar structure are set at a first angle. When the first angle is greater than 90°, the deformed steel bar structure is in a quadrangular prism shape, and the horizontal bars are in a U shape.

[0013] Furthermore, after installing a plurality of embedded vertical bars, tension bars are installed on the embedded vertical bars, and one end of the tension bar away from the embedded vertical bars extends into the cylindrical steel bar structure.

[0014] Furthermore, the curved outer walls connected on both sides of the cylindrical steel bar structure are set at a second angle. When the second angle is less than or equal to 90°, the deformed steel bar structure is in a triangular prism shape, and the horizontal bars are in a straight line shape.

[0015] The beneficial effect of the present invention is that the construction method of the joint structure in which the cylinder and the curved outer wall are connected is to patch the cylindrical part exposed on the curved outer wall to form a triangular column or a quadrangular column, and adopt wooden formwork for construction. Among them, the formwork of one side of the quadrangular column (that is, the middle column formwork of the three-sided formwork) is fixed in size and can be prepared uniformly, and the remaining formworks are prepared separately using wooden formworks. On the other hand, only one side of the formwork needs to be prepared for the triangular column, which reduces the construction cost of the formwork project. The curved outer wall and the square column are constructed simultaneously, and the construction is convenient and fast, the operation is simple, the construction period is short, and the cost is low.

[0020] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Reference Figures 1 to 3 As shown, the present invention provides a construction method for a joint structure in which a cylinder and a curved outer wall are connected, comprising the following steps:

[0023] S1. A wall formwork is set up at the construction position of the curved outer wall 1 of the joint structure, and a notch is formed in the wall formwork at the construction position of the column 2 of the joint structure.

[0024] S2. Tie the cylindrical reinforcement structure at the construction position of column 2.

[0025] S3. Install multiple embedded vertical bars 31 on opposite sides of the cylindrical steel structure exposed at the notch.

[0026] S4. Horizontal bars 32 are connected to the outside of multiple embedded vertical bars 31. The two ends of the horizontal bars 32 extend into the casting space of the curved outer wall 1 connected on both sides of the cylindrical steel structure. The embedded vertical bars 31 and the horizontal bars 32 and the side of the cylindrical steel structure exposed in the gap form a triangular prism or a quadrangular prism-shaped deformed steel structure 3. The length of the cross section of the deformed steel structure 3 is adapted to the outer diameter of the cylindrical steel structure.

[0027] S5. Set up column formwork outside the deformed steel bar structure 3 so that the column formwork and the wall formwork are closed to form a closed casting space.

[0028] S6. Concrete is poured in the closed pouring space, and the concrete is wrapped around the cylindrical steel structure and the deformed steel structure 3 to consolidate and form a joint structure.

[0029] See Figure 1 As shown, the curved outer walls 1 connected on both sides of the cylindrical steel bar structure are set at a first angle. When the first angle is greater than 90°, the deformed steel bar structure 3 is in a quadrangular prism shape and the horizontal bar 32 is in a U shape.

[0030] After installing a plurality of embedded vertical bars 31 , a tension bar 33 is installed on the embedded vertical bars 31 , and one end of the tension bar 33 away from the embedded vertical bars 31 extends into the cylindrical steel bar structure.

[0031] See Figure 2 As shown, the curved outer wall 1 connected to the two sides of the cylindrical steel structure is arranged at a first angle. When the first angle is greater than 90 degrees, the deformed steel structure 3 is in the shape of a quadrangular prism, and the horizontal reinforcement 32 is in the shape of a U. The opposite sides of the cylindrical steel structure are exposed on the outside of the curved outer wall.

[0032] See Figure 3As shown, the curved outer walls 1 connected on both sides of the cylindrical steel bar structure are set at a second angle. When the second angle is less than or equal to 90°, the deformed steel bar structure 3 is in a triangular prism shape and the horizontal bar 32 is in a straight line shape.

[0033] In this embodiment, there are three ways to connect the curved exterior wall and the column:

[0034] Type 1: A cylinder is connected to a curved outer wall (i.e., the curved outer walls on both sides of the cylinder are arranged at a first angle), and one side of the cylinder does not pass through the curved outer wall;

[0035] The second type: a cylinder is connected to a curved outer wall (i.e., the curved outer walls on both sides of the cylinder are arranged at a first angle), and opposite sides of the cylinder pass through the curved outer wall;

[0036] The third type: the cylinder is connected to two curved outer walls (i.e., the curved outer walls on both sides of the cylinder are set at a second angle), and the cylinder does not pass through the curved outer walls.

[0037] The construction method of the joint structure of a circular column and a curved outer wall of the present invention carries out a detailed design of the circular column connected to the curved outer wall, and the portion of the circular column exposed from the curved outer wall is patched to form a square column or a triangular column.

[0038] When optimizing the first type of structure, the cylindrical sections not connected to the curved wall are converted to square columns, and embedded vertical reinforcement and U-shaped horizontal reinforcement are added. When the cylinder diameter is ≥800mm, additional tie bars are added, with every other tie bar added. For the first type of deformed steel structure, three column formwork is used: the width of the center column formwork is adapted to the outer diameter of the cylinder, and the remaining two column formworks are fabricated based on actual conditions.

[0039] When optimizing the second type of form, the cylindrical sections not connected to the curved wall are converted to square columns, and embedded vertical reinforcement and U-shaped horizontal reinforcement are added. For columns with a diameter ≥ 800mm, tie bars are added, with every other tie bar added. For the second type of deformed steel structure, three column formwork is used: the width of the center column formwork is adapted to the outer diameter of the cylinder, and the remaining two column formworks are fabricated based on actual conditions.

[0040] When optimizing the third type of form, the cylindrical part that is not connected to the curved wall is changed into a triangular column, and embedded vertical reinforcement and tension reinforcement are added, and only one side of the column formwork is required.

[0041] The method for constructing a joint structure in which a circular column and an arc-shaped outer wall are connected to each other includes synchronous construction of the arc-shaped outer wall and the square column, synchronous binding of steel bars, synchronous erection of wooden formwork, and synchronous pouring of concrete.

[0042] Traditional circular steel formwork is used in the construction of circular columns. The angles and locations of the connections between the columns and the curved walls vary, and using traditional circular steel formwork would require the customization of hundreds of irregular circular steel formworks. This is difficult and time-consuming, and cannot be reused, resulting in high costs.

[0043] The construction method of the joint structure in which the cylinder and the curved outer wall are connected in the present invention is to patch the cylindrical part exposed from the curved outer wall to form a triangular column or a quadrangular column, and adopt wooden formwork for construction. Among them, the formwork of one side of the quadrangular column (that is, the middle column formwork of the three-sided formwork) is fixed in size and can be prepared uniformly, and the remaining formworks are prepared separately using wooden formworks. On the other hand, only one side of the formwork needs to be prepared for the triangular column, which reduces the construction cost of the formwork project. The curved outer wall and the square column are constructed simultaneously, and the construction is convenient and fast, the operation is simple, the construction period is short, and the cost is low.

[0044] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
