Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated building vertical annular dowel fixing structure and a method thereof. Background Art

[0002] In the design and construction process of prefabricated buildings, the combination of transverse and longitudinal steel bars is an extremely common and efficient means of structural reinforcement. This combination can significantly improve the overall stability and load-bearing capacity of the building, and effectively respond to various complex external forces, such as the impact of natural disasters such as wind and earthquakes. However, under specific design requirements or special structural forms, such as certain circular or curved building components, the traditional transverse and longitudinal steel bar configuration may no longer be applicable, and instead a layout combining circular and longitudinal steel bars may be adopted.

[0003] The introduction of circular reinforcement is mainly to adapt to changes in structural shape and enhance the stress-bearing performance of components in the circumferential direction, especially when subjected to uniformly distributed pressure or tension, it can provide a more uniform stress distribution. However, at the same time, the combination of circular reinforcement and longitudinal reinforcement also brings certain challenges. Due to the particularity of circular reinforcement, during the construction process, if circular reinforcement of different diameters is required due to design changes, changes in site conditions or calculation errors, this often means that the construction team needs to respond quickly and conduct emergency scheduling or re-purchase of materials. This process is not only time-consuming and labor-intensive, but may also affect the progress of the entire project due to delays in material supply. In addition, special attention should be paid to the intersection treatment of the circular reinforcement and the longitudinal reinforcement to ensure a stable connection and do not affect the mechanical properties of the overall structure.

[0004] In terms of the choice of connection method, although bolt connections are widely used in prefabricated buildings due to their easy installation and strong disassembly, compared with the concrete injection method, bolt connections have certain shortcomings in strength and durability. Bolt connections may cause the connection strength to decrease due to loosening, corrosion and other problems, thereby affecting the safety of the structure. In addition, bolt connections may also increase the maintenance cost and difficulty of the structure, and regular inspection and maintenance are required to ensure it is in good condition.

[0005] Therefore, there is an urgent need for a prefabricated building vertical annular dowel fixing structure and method thereof to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a vertical annular dowel fixing structure for prefabricated buildings and a method thereof, which has the advantages of easy adjustment and good stability, and solves the problems raised by the above-mentioned background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a prefabricated building vertical annular dowel fixing structure, comprising: annular components, wherein the number of the annular components is two and they are symmetrically arranged;

[0008] The annular assembly includes three sleeves, the inner cavities of two adjacent sleeves are commonly provided with arc-shaped steel bars, and one side of the sleeve surface is connected to an injection pipe and a discharge pipe;

[0009] The inner cavity of the annular component is provided with an adjustment component;

[0010] The adjusting assembly includes a shell, a motor is fixedly connected to the right side of the top of the inner cavity of the shell, the output shaft of the motor is fixedly connected to the driving gear, the inner cavity of the shell is rotatably connected to a round rod, the top of the surface of the round rod is fixedly connected to the driven gear, the driven gear is meshed with the driving gear, and the bottom of the surface of the round rod is fixedly connected to a rotating disk, three movable holes are opened on one side of the rotating disk, the inner cavity of the movable hole is slidably connected to a movable rod, the bottom end of the movable rod is fixedly connected to an adjusting plate, one side of the adjusting plate extends to the outside of the shell, a stabilizing block is provided on the surface of the adjusting plate, and one side of the stabilizing block is fixedly connected to the sleeve;

[0011] Three vertical components are arranged between the two annular components;

[0012] The vertical component includes vertical steel bar 1 and vertical steel bar 2 in contact with the annular component, and the opposite sides of the vertical steel bar 1 and vertical steel bar 2 are fixedly connected with threaded rod 1 and threaded rod 2 respectively, and the surfaces of the threaded rod 1 and threaded rod 2 are commonly threadedly connected with a threaded pipe.

[0013] Furthermore, as a preferred embodiment of the present invention, a handle is fixedly connected to the top of the shell, and the handle is concave in shape.

[0014] Furthermore, as a preferred embodiment of the present invention, a positioning hole is opened on one side of the sleeve, and the positioning hole is used in conjunction with the vertical steel bar 1 and the vertical steel bar 2.

[0015] Furthermore, as a preferred embodiment of the present invention, the top end of the movable rod extends to the outside of the movable hole and is fixedly connected to a positioning block, and the diameter of the positioning block is larger than the diameter of the movable rod.

[0016] Furthermore, as a preferred embodiment of the present invention, three sliding holes are opened on the surface of the shell, and the inner cavities of the sliding holes are slidably connected to the adjustment plate.

[0017] Furthermore, as a preferred embodiment of the present invention, a guide groove is provided at the top of the threaded rod 1, the inner cavity of the guide groove is slidably connected to a guide rod, and the top end of the guide rod is fixedly connected to the threaded rod 2.

[0018] Furthermore, as a preferred embodiment of the present invention, the surface of the threaded pipe is provided with anti-slip grooves.

[0019] Furthermore, as a preferred embodiment of the present invention, the threads on the surfaces of the threaded rod one and the threaded rod two are arranged in opposite directions.

[0020] In the present invention, a method for using a vertical annular dowel fixing structure for an assembled building comprises the following steps:

[0021] Step 1: Place the adjusting assembly in the middle position of the annular assembly, start the motor, and the output shaft of the motor drives the driving gear to rotate. Since the driving gear and the driven gear are meshed, the driving gear will drive the driven gear to rotate when it rotates. When the driven gear rotates, it drives the round rod to rotate on the inner wall of the shell. When the round rod rotates further, it drives the rotating disk to move in the same direction. When the rotating disk moves, it drives the movable rod to move under the action of the movable hole. The movable rod pushes the adjusting plate to move toward the outside of the shell, and makes one side of the adjusting plate stuck in the inner cavity of the stabilizing block. The motor is continuously started, which can make the adjusting plate continue to expand outward, thereby driving the sleeve to expand outward. At this time, the arc-shaped steel bar will slide in the inner cavity of the two sleeves to improve the integrity of the annular assembly. This process plays a role in adjusting the diameter of the annular assembly.

[0022] Step 2: Use the method in step 1 to adjust the other annular components to the required size, then insert the bottom end of the vertical steel bar 1 into the inner cavity of the positioning hole, and then inject concrete into the inner cavity of the injection pipe. The concrete fills the inner cavity of the sleeve until the sleeve is filled with concrete and the excess overflows from the discharge pipe. This step not only fixes the shape of the annular component, but also achieves a stable connection between the annular component and the vertical steel bar 1;

[0023] Step 3: At this time, the vertical steel bar 1 and the ring assembly are fixed by concrete. Then, the threaded tube is rotated. When the threaded tube rotates, it moves upward on the surface of the threaded rod 1. When the threaded tube moves upward and rotates, it drives the threaded rod 2 to move upward. The threaded rod 2 drives the guide rod to slide in the inner cavity of the guide groove to guide the vertical steel bar 2 to prevent the vertical steel bar 2 from rotating. Then, another ring assembly is placed on the top of the fixed vertical assembly, and the vertical steel bar 2 is inserted into its positioning hole. The concrete injection process of step 2 is repeated to achieve the fixation of the vertical steel bar 2 and the upper ring assembly, which allows the distance between multiple ring assemblies to be adjusted.

[0024] Step 4: According to actual needs, multiple combinations of annular components and vertical components can be set up. To this end, positioning holes are provided at the top and bottom of the sleeve to facilitate the precise positioning and connection of vertical steel bar 1 and vertical steel bar 2, thereby constructing a stable and flexible multi-layer structure.

[0025] Beneficial effects, the technical solution of the present application has the following technical effects: the present invention has the advantages of easy adjustment and good stability. In actual use, the annular component and the vertical component are designed;

[0026] First, multiple structures are used in conjunction to form a ring structure. At this time, under the action of the adjustment component, it is convenient for construction workers to easily adjust the diameter of the ring component according to actual needs on site, thereby achieving flexible adjustment of the diameter of the ring component;

[0027] The vertical components adopt a telescopic design. Through the built-in structure, the length of the vertical components can be adjusted, making the structure more flexible when dealing with different height requirements.

[0028] In order to achieve a stable connection between the annular component and the vertical component, the pouring fixation technology is adopted. During the construction process, the adjusted vertical component is inserted into the inner cavity of the annular component, and then the energy concrete is injected into the inner cavity of the annular component through the injection pipe. This material can form a strong bonding force after hardening, firmly connecting the annular component and the vertical component together to form an overall stable structure.

[0057] In the present invention, a method for using a vertical annular dowel fixing structure for an assembled building comprises the following steps:

[0058] Step 1: Place the adjustment component 2 in the middle of the ring component 1, start the motor 202, and the output shaft of the motor 202 drives the driving gear 203 to rotate. Since the driving gear 203 and the driven gear 205 are engaged, the driving gear 203 rotates and drives the driven gear 205 to rotate. When the driven gear 205 rotates, it drives the round rod 204 to rotate on the inner wall of the shell 201. Further, when the round rod 204 rotates, it drives the rotating disk 206 to move in the same direction. When the rotating disk 206 moves, it moves in the movable hole 21. 0, the movable rod 207 is driven to move, and the movable rod 207 pushes the adjustment plate 208 to move toward the outside of the shell 201, and makes one side of the adjustment plate 208 get stuck in the inner cavity of the stabilizing block 209. The motor 202 is continuously started, which can make the adjustment plate 208 continue to expand outward, thereby driving the sleeve 101 to expand outward. At this time, the arc-shaped steel bar 102 will slide in the inner cavity of the two sleeves 101, which is used to improve the integrity of the annular component 1. This process plays a role in adjusting the diameter of the annular component 1;

[0059] Step 2: Use the method of step 1 to adjust the other annular components 1 to the required size, then insert the bottom end of the vertical steel bar 31 into the inner cavity of the positioning hole 105, and then inject concrete into the inner cavity of the injection pipe 103. The concrete fills the inner cavity of the sleeve 101 until the sleeve 101 is filled with concrete and the excess overflows from the discharge pipe 104. This step not only fixes the shape of the annular component 1, but also achieves a stable connection between the annular component 1 and the vertical steel bar 31;

[0060] Step 3: At this time, the vertical steel bar 1 31 and the ring component 1 are fixed by concrete. Then, the threaded tube 35 is rotated. When the threaded tube 35 rotates, it moves upward on the surface of the threaded rod 1 33. When the threaded tube 35 moves upward and rotates, it drives the threaded rod 2 34 to move upward. The threaded rod 2 34 drives the guide rod 37 to slide in the inner cavity of the guide groove 36 to guide the vertical steel bar 2 32 to prevent the vertical steel bar 2 32 from rotating. Then, another ring component 1 is placed on the top of the fixed vertical component 3, and the vertical steel bar 2 32 is inserted into its positioning hole 105. The concrete injection process of step 2 is repeated to achieve the fixation of the vertical steel bar 2 32 and the upper ring component 1, which allows the distance between multiple ring components 1 to be adjusted.

[0061] Step 4: According to actual needs, multiple combinations of annular components 1 and vertical components 3 can be set up. To this end, positioning holes 105 are provided at the top and bottom of the sleeve 101 to facilitate the precise positioning and connection of vertical steel bar 1 31 and vertical steel bar 2 32, thereby constructing a stable and flexible multi-layer structure.
