Description

Technical Field

[0001] The utility model relates to a core tube structure, in particular to a steel frame core tube structure used for same-layer construction-tower type material placing crane combined construction. Background Art

[0002] Tower concrete placing boom is an efficient and flexible concrete conveying equipment, which is widely used in high-rise building construction. It uses tower crane standard sections as support, combines the tower body with the upper part of the concrete placing boom, and has the dual functions of placing materials and adding tower crane sections. As the building rises, the concrete placing boom can be raised by adding standard sections through its own climbing frame and can be attached to the building wall through the wall bracket. The core tube structure is a mainstream structural form widely used in high-rise and super-high-rise buildings. This structure mainly consists of an outer beam-column frame force-bearing system and a central core tube, where the core tube is located in the central part of the building. In conventional construction, a tower concrete placing boom is set on the side of the building to assist in the construction of the core tube. However, in actual use, it is found that due to the extension length limitation of the tower concrete placing boom, it is usually necessary to start from one end of the building and gradually extend toward the other end. The single-story area of ​​the same-story construction is large, and it is impossible to pour concrete in one go, resulting in low efficiency of the same-story construction. Therefore, a steel frame core tube structure for the combined construction of same-story construction and tower concrete placing boom is needed. The device can set the tower concrete placing boom in the middle of the core tube, facilitating circular construction with the core tube as the center, so that the concrete can be poured in one go during the same-story construction, improving processing efficiency.

[0003] Considering the above reasons, how to set the tower concrete placing boom in the middle of the core tube is exactly the problem considered in this application. Utility Model Content

[0004] In response to the shortcomings of the existing technology, a steel frame core tube structure for same-layer construction and tower-type concrete placing boom combined construction is provided. The device can set the tower-type concrete placing boom in the middle of the core tube, facilitating circular construction with the core tube as the center, thereby achieving one-time pouring during same-layer construction and improving processing efficiency.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: a steel frame core tube structure for the combined construction of same-layer construction and tower-type concrete placing boom, comprising a positioning tube, a track assembly being provided on the positioning tube, the track assembly being connected to a moving assembly mounted on the concrete placing boom, the track assembly comprising an isolation tube fixedly connected to the positioning tube, the isolation tube being provided with a spirally arranged guide rail, the moving assembly comprising a roller connected to the guide rail and a base for connecting to the concrete placing boom.

[0006] In summary, the above technical solution has the following beneficial effects: the tower body of the tower concrete distributor is commonly rectangular or cylindrical. The rectangular tower body is easy to assemble but requires cables to directly pull the tower to move. The cylindrical tower body guides the tower to rotate and rise through its own track and is usually used in conjunction with a spider-web tower. The tower distributor in the utility model can adopt both.

[0007] When a rectangular tower body is used, the pulling force required to pull the tower frame is very large, so the cable and the supporting power components occupy a large area and are not suitable for installation in the isolation tube. Therefore, an additional moving ring rotating around the tower body can be installed, and the base is fixedly connected to the moving ring. In this way, when the roller rotates along the guide rail, the moving ring will also rotate. Since the guide rail is spirally arranged, it can drive the movement of the tower body in the vertical direction. In this way, the cable and the supporting power components are no longer needed, or the cable and the supporting power components are assisted by a device with less power, so that the rectangular tower body and the tower frame can be smoothly used in the core tube, so that the tower placing crane can be set in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that the same-layer construction can be poured at one time, thereby improving the processing efficiency.

[0008] When a cylindrical tower body is used, since the tower frame itself relies on the threaded track on the tower frame to move up and down, the strength of the threaded track itself is required to be relatively high. In the utility model, it is only necessary to adapt the guide rail to the threaded track on the tower frame, and then directly connect the base to the tower frame for direct use. In addition, the threaded track and the guide rail can form a clamping effect from the inside and outside to relatively fix the tower frame, thereby preventing the tower frame from falling off, and distributing the pressure of the tower frame to the threaded track and the guide rail, reducing the strength of the threaded track, saving construction costs from the side, and at the same time, the tower-type concrete placing machine can be set in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that the same-layer construction can be poured at one time, thereby improving processing efficiency.

[0009] The use of spiral guide rails to drive the tower to move upward can accurately control the size and speed of the material, effectively avoid waste, and improve construction efficiency. The design of the spiral guide rail can make the movement process more continuous and stable, reducing energy consumption and time loss caused by frequent position adjustments. In addition, since the material placing boom is installed inside the core tube, the use space is relatively limited. The spiral guide rail upward movement method greatly reduces the tower's dependence on the power device, which is particularly suitable for workplaces with limited space. Through the vertical pipe transportation method, the tower type material placing boom can transport the material in three dimensions, improving space utilization.

[0010] The utility model realizes the vertical movement of the tower frame by arranging a spiral guide rail and a matching roller, and is adapted to two common tower body shapes. The tower-type material placing machine can be arranged in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that the same-layer construction can be poured at one time, thereby improving processing efficiency.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0018] Reference Figure 1-3 As shown, the steel frame core tube structure used for the combined construction of same-level construction and tower-type concrete placing boom includes a positioning tube 1, a track assembly 2 provided on the positioning tube 1, and a moving assembly 3 mounted on the concrete placing boom connected to the track assembly 2. The track assembly 2 includes an isolation tube 21 fixedly connected to the positioning tube 1, and a spirally arranged guide rail 22 provided on the isolation tube 21. The moving assembly 3 includes a roller 31 connected to the guide rail 22 and a base 32 for connecting to the concrete placing boom.

[0019] The tower bodies of tower concrete distributors are commonly rectangular and cylindrical. The rectangular tower body is easy to assemble but requires cables to directly pull the tower body to move. The cylindrical tower body uses its own track to guide the tower body to rotate and rise. It is usually used in conjunction with a spider-web tower. The tower distributor in this utility model can adopt both.

[0020] When a rectangular tower body is used, the pulling force required to pull the tower frame is very large, so the cable and the supporting power assembly occupy a large area and are not suitable for installation in the isolation tube 21. Therefore, an additional moving ring rotating around the tower body can be installed, and the base 32 is fixedly connected to the moving ring. In this way, when the roller 31 rotates along the guide rail 22, the moving ring will also rotate. Since the guide rail 22 is spirally arranged, it can drive the movement of the tower body in the vertical direction. In this way, the cable and the supporting power assembly are no longer needed, or the cable and the supporting power assembly are assisted by a device with less power, so that the rectangular tower body and the tower frame can be used smoothly in the core tube, so that the tower placing machine can be set in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that one-time pouring is carried out during the same-layer construction, thereby improving processing efficiency;

[0021] When a cylindrical tower body is used, since the tower frame itself relies on the threaded track on the tower frame to move up and down, the strength requirement of the threaded track itself is relatively high. In the present invention, it is only necessary to adapt the guide rail 22 to the threaded track on the tower frame, and then directly connect the base 32 to the tower frame for direct use. In addition, the threaded track and the guide rail 22 can form a clamping effect from the inside and outside to relatively fix the tower frame, thereby preventing the tower frame from falling off, and distributing the pressure of the tower frame to the threaded track and the guide rail 22, reducing the strength requirement of the threaded track, saving construction costs from the side, and at the same time, the tower-type concrete placing machine can be set in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that the same-layer construction can be poured at one time, thereby improving processing efficiency.

[0022] The use of a spiral guide rail 22 to drive the tower to move upward can accurately control the size and speed of the material, effectively avoid waste, and improve construction efficiency. The design of the spiral guide rail 22 can make the movement process more continuous and stable, reducing energy consumption and time loss caused by frequent position adjustments. In addition, since the material placing boom is installed inside the core tube, the use space is relatively limited. The upward movement of the spiral guide rail 22 greatly reduces the tower's dependence on the power device, which is particularly suitable for workplaces with limited space. Through the vertical pipe transportation method, the tower type material placing boom can transport the material in three dimensions, improving space utilization.

[0023] The utility model realizes the vertical movement of the tower frame by providing a spiral guide rail 22 and a matching roller 31, and is adapted to two common tower body shapes. The tower-type concrete placing machine can be set in the middle of the core tube, which is convenient for circular construction with the core tube as the center, so that the same-layer construction can be poured at one time, thereby improving processing efficiency.

[0024] Furthermore, the guide rail 22 is fixedly connected with a plurality of protruding gear teeth 23, and the roller 31 is provided with a plurality of first receiving grooves 24 for receiving the gear teeth 23;

[0025] Since the material spreading machine is a large-scale machine, in order to increase the connection strength between the guide rail 22 and the roller 31, the gear teeth 23 are provided to cooperate with the first receiving groove 24, so that a structure similar to the gear meshing transmission can be formed, which greatly improves the transmission efficiency and makes the structure more compact, which can further prevent the roller 31 from disengaging.

[0026] Furthermore, the isolation cylinder 21 is further provided with two insertion slots 25 arranged along the guide rail 22 and respectively arranged at the upper and lower ends of the guide rail 22, and the roller 31 is fixedly connected with insertion plates 33 respectively arranged at the upper and lower ends of the roller 31;

[0027] When the roller 31 rotates along the guide rail 22, the two insert plates 33 can be respectively inserted into the corresponding insert slots 25. This can further strengthen the overall compactness of the connection between the roller 31 and the guide rail 22 through the form of plug-in connection, and can share the force of the gear teeth 23, which can not only further prevent the roller 31 from being disengaged, but also prevent the roller 31 and the guide rail 22 from being broken.

[0028] Furthermore, the base 32 is rotatably connected to a first lifting arm 34, and the first lifting arm 34 is slidably connected to a connecting plate 35 rotatably connected to the roller 31. The base 32 is also slidably connected to a second lifting arm 36 rotatably connected to the connecting plate 35. The first lifting arm 34 and the second lifting arm 36 intersect and are hinged at the center.

[0029] The roller 31 is also fixedly connected to a plurality of positioning posts 37 disposed in the first receiving groove 24. The gear teeth 23 are provided with a second receiving groove 26 for receiving the positioning posts 37. The cross section of the insertion groove 25 away from the guide rail 22 is trapezoidal.

[0030] The base 32 is also fixedly connected to a first remote-controlled motor 38 for driving the second lifting arm 36 to slide, and the connecting plate 35 is fixedly connected to a second remote-controlled motor 39 for driving the roller 31 to rotate;

[0031] The second remote-controlled motor 39 can remotely control the rotation of the roller 31, thereby controlling the movement of the tower. In addition, the second remote-controlled motor 39 can be omitted and connected to other power-providing devices through connecting belts and other components to achieve simultaneous rotation of multiple rollers 31.

[0032] The first remote-controlled motor 38 can remotely control the left and right movement of the second lifting arm 36. Since the first lifting arm 34 and the second lifting arm 36 intersect and are hinged at the center, the combination of the first lifting arm 34 and the second lifting arm 36 can enable the roller 31 to move closer to the guide rail 22. After the roller 31 moves closer to the guide rail 22, the positioning post 37 is accommodated in the second accommodating groove 26, thereby preventing the roller 31 from rotating. In addition, the insertion plate 33 penetrates into the trapezoidal cross-section of the insertion groove 25. Under the action of the extrusion of the inclined inner wall, the contact area between the insertion plate 33 and the inner wall of the insertion groove 25 increases, thereby increasing the friction force, which can further prevent the roller 31 from rotating.

[0033] In addition, the positioning post 37 received in the second receiving groove 26 can further prevent the roller 31 from being separated and prevent the roller 31 and the guide rail 22 from being broken.

[0034] Furthermore, the roller 31 can be detachably connected to an elastic protective ring 4. Since the roller 31 is relatively large, in order to prevent debris from entering the first receiving groove 24 or the positioning column 37 from being impacted and damaged during transportation, the elastic protective ring 4 is embedded between the two insertion plates 33, thereby covering the first receiving groove 24 and playing a protective role.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
