Description

Technical Field

[0001] This application relates to the field of building steel structure technology, and in particular to a steel structure transfer layer. Background Technology

[0002] In large public buildings, such as auditoriums and concert halls, which have long spans, a transfer floor is usually required at the top of the building to transfer loads and divide the space. Currently, such buildings mostly use reinforced concrete transfer floors or traditional steel truss structures. In recent years, with the development of prefabricated building technology, the application of modular steel structure transfer floors has gradually increased. However, there is still room for improvement in terms of installation accuracy control, overall stability, and maintenance convenience under long span conditions.

[0003] An existing patent (publication number: CN216690012U) discloses a high-load-bearing and easily assembled inter-beam transfer layer. The transfer layer is located between two adjacent structural beams under the structural roof slab and includes prefabricated brackets anchored to the sides of the beams and a suspended steel frame laid on the prefabricated brackets. The prefabricated brackets are spaced apart along the length of the structural beams. Each prefabricated bracket includes a vertical rod anchored to the side facade of the structural beam and a horizontal rod with one end anchored to the vertical rod and the other end extending horizontally outward. The vertical rod is fixedly connected to the structural beam by bolts or reinforcing bars that penetrate the vertical rod and horizontally insert into the structural beam. In this invention, the transfer layer is supported by bolts or reinforcing bars driven horizontally into the structural beam, greatly improving the maximum load-bearing capacity and reliability of the transfer layer. The prefabricated brackets, suspended steel frame, and other components are all prefabricated and installed on the sides of the structural beams using bolting, which not only allows for quick assembly but also ensures that secondary disassembly and modification will not affect the original structure.

[0004] However, it was found in the above solution that the hoisting system does not have an adjustment function after the steel structure is hoisted, resulting in the steel structure being fixed in position, which makes it difficult for the device to adapt to the installation requirements of different building heights. Utility Model Content

[0005] The purpose of this application is to provide a steel structure transfer layer that has the advantages of being able to level H-beams and position and install them, thereby improving construction efficiency and adapting to the installation requirements of different building heights, thus solving the problems mentioned in the background art.

[0006] The steel structure transfer layer provided in this application adopts the following technical solution: it includes a concrete roof slab, the inner wall of which is fixedly connected with chemical anchors arranged at equal intervals. Each chemical anchor has a mounting base fixedly connected to its bottom end, and each mounting base has a fixing base fixedly connected to its bottom surface. Each fixing base has an adjusting screw fixedly connected to its inner wall, and each adjusting screw has a threaded cylinder threadedly connected to its outer surface. Each threaded cylinder has a support rod rotatably connected to its inner wall, and each support rod has a first flange fixedly connected to its bottom end. Two H-beams are provided below the concrete roof slab, and two second flanges are fixedly connected to the upper surface of each H-beam. Each second flange is fixedly connected to a corresponding first flange with equally spaced first fixing bolts. Each support rod has a guide rod fixedly connected to its inner bottom wall, and the outer surface of each guide rod is slidably connected to the inner wall of the corresponding adjusting screw.

[0007] By adopting the above technical solution, chemical anchors arranged at equal intervals are installed on the inner wall of the concrete roof slab, allowing the chemical anchors to be fixed to the inner wall of the concrete roof slab. The mounting base is fixed to the bottom end of the chemical anchors, allowing the mounting base to be installed below the concrete roof slab. A fixing seat is set on the bottom surface of the mounting base, and an adjusting screw is installed on the inner wall of the fixing seat. The adjusting screw is fixed to the bottom surface of the mounting base through the fixing of the fixing seat and the mounting base. A threaded cylinder is set on the outer surface of the adjusting screw, and a threaded connection is made between the threaded cylinder and the adjusting screw. This allows the threaded cylinder to rise and fall along the adjusting screw when the operator rotates it. A support rod is set on the inner wall of the threaded cylinder, configured as a rotatable connection, to limit the movement of the support rod, thus allowing the threaded cylinder to move up and down during lifting. The movable support rod is raised and lowered, and the H-beam is placed below the concrete roof slab. A second flange is installed on the upper surface of the H-beam, and a first flange is placed at the bottom of the support rod. The first flange is fixed to the second flange by first fixing bolts arranged at equal intervals. A guide rod is installed on the inner bottom wall of the support rod, and the guide rod is slidably connected to the adjusting screw. When the threaded cylinder is connected to the adjusting screw for raising and lowering, the support rod will only rise and fall along the direction of the adjusting screw, without generating rotational force. This allows the operator to raise and lower the support rod by rotating the threaded cylinder, thereby raising and lowering the corresponding H-beam. This achieves the positioning and installation of the H-beam, improving construction efficiency and adapting to the installation requirements of different building heights.

[0008] Preferably, the two H-beams are fixedly connected to each other on their adjacent sides, and a box-section secondary beam is provided between the two H-beams.

[0009] By adopting the above technical solution, the connecting part is installed on the side of the H-beam main beam that is close to each other, and is set as a fixed connection to fix the connecting part. The box-section secondary beam is set between the two H-beam main beams and is set at a 90-degree angle to the H-beam main beam.

[0010] Preferably, each of the connecting parts is provided with two third fixing bolts on both the front and back sides.

[0011] By adopting the above technical solution, the third fixing bolt is set on the front and back of the connection part, and the third fixing bolt is set at the position where the connection part is connected to the box-section secondary beam.

[0012] Preferably, each of the third fixing bolts has a connecting plate arranged at equal intervals fixedly installed on its inner wall, and each connecting plate is fixedly installed with the corresponding connecting part and the inner wall of the box-shaped secondary beam.

[0013] By adopting the above technical solution, the connecting plate is installed on the inner wall of the corresponding third fixing bolt, and the connecting plate is fixed to the corresponding connecting part and the box-shaped secondary beam, so that the third fixing bolt and the connecting plate can be connected to the corresponding connecting part and the box-shaped secondary beam, thereby enabling the connecting part and the box-shaped secondary beam to be spliced. At this time, the H-shaped steel main beam, the connecting part and the box-shaped secondary beam form a steel beam frame.

[0014] Preferably, the upper surface of the box-shaped secondary beam is provided with an anti-slip grating tread, and the front and back of the anti-slip grating tread are fixedly connected with connectors arranged at equal intervals.

[0015] By adopting the above technical solution, anti-slip grating steps are set on the upper surface of the box-section secondary beam, and connecting parts are set on both the front and back of the anti-slip grating steps, allowing maintenance personnel to walk and work directly through the anti-slip grating steps.

[0016] Preferably, a second fixing bolt is fixedly installed on the inner wall of each of the connectors, and each of the second fixing bolts is fixedly installed with the box-shaped secondary beam.

[0017] By adopting the above technical solution, the second fixing bolt is installed on the inner wall of the connector to form a fixed connection, and the second fixing bolt is connected to the box-shaped secondary beam, so that the connector can be fixed on the upper flange of the box-shaped secondary beam, and the anti-slip grating pedal can be installed on the upper flange of the box-shaped secondary beam.

[0018] Preferably, two horizontal bars are provided above the box-shaped secondary beam, and each horizontal bar is fixedly connected to a vertical bar arranged at equal intervals on its bottom surface, and the bottom end of each vertical bar is fixedly connected to the upper surface of the box-shaped secondary beam.

[0019] By adopting the above technical solution, the horizontal bar is set above the box-section secondary beam, and vertical bars arranged at equal intervals are installed on the bottom surface of the horizontal bar. The bottom end of the vertical bar is fixed to the upper surface of the box-section secondary beam, so that the horizontal bar and vertical bar can be installed on the upper surface of the box-section secondary beam.

[0020] Preferably, each of the horizontal bars is provided with connecting rods arranged at equal intervals below it, and the end of each connecting rod is fixedly connected to the outer surface of the corresponding vertical bar.

[0021] By adopting the above technical solution, the connecting rod is placed below the vertical rod, and the end of the connecting rod is fixed to the corresponding vertical rod, so that the horizontal rod, vertical rod and connecting rod can form a guardrail and be fixed on the upper surface of the box-section secondary beam. When used together with the anti-slip grating pedal, the safety of operation and maintenance can be improved.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This steel structure transfer layer, through the installation of components such as chemical anchors, adjusting screws, threaded cylinders, and guide rods, firstly, fixes the chemical anchors to the concrete top slab. Then, connects the first and second flanges with the first fixing bolt, allowing the H-beam main beam to be hoisted. Rotating the corresponding threaded cylinder allows it to rise and fall along the adjusting screw. Through the sliding connection between the guide rod and the adjusting screw, the support rod can follow the threaded cylinder to rise and fall, thereby achieving leveling of the H-beam main beam and positioning installation. This improves construction efficiency and can adapt to the installation requirements of different building heights. By setting the second fixing bolt, the connector can be installed on the upper surface of the box-section secondary beam. Due to the fixation of the anti-slip grating pedal to the connector, the anti-slip grating pedal can be installed on the upper surface of the box-section secondary beam. Through the fixation of the horizontal bars, vertical bars, and connecting rods, and fixing the bottom end of the vertical bar to the upper surface of the box-section secondary beam, this device allows operators to walk easily by setting the anti-slip grating pedal. The use of guardrails in conjunction with the anti-slip grating pedal can improve operation and maintenance safety. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A steel structure transfer floor, please refer to [link / reference]. Figure 1 , Figure 3 and Figure 4 The system includes a concrete roof slab 1, with chemical anchors 2 arranged at equal intervals fixedly connected to the inner wall of the concrete roof slab 1. The chemical anchors 2 are fixed to the inner wall of the concrete roof slab 1. Each chemical anchor 2 has a mounting base 4 fixedly connected to its bottom end. The mounting base 4 is fixed to the bottom end of the chemical anchor 2, allowing it to be installed below the concrete roof slab 1. Each mounting base 4 has a fixing seat 5 fixedly connected to its bottom surface. The inner wall of each fixing seat 5 is fixed... An adjusting screw 6 is connected to a mounting base 4. A fixed base 5 is set on the bottom surface of the mounting base 4, and the adjusting screw 6 is installed on the inner wall of the fixed base 5. The adjusting screw 6 can be installed on the bottom surface of the mounting base 4 by fixing it to the fixed base 5 and the mounting base 4. A threaded cylinder 7 is threadedly connected to the outer surface of each adjusting screw 6. The threaded cylinder 7 is set on the outer surface of the adjusting screw 6, and the threaded cylinder 7 and the adjusting screw 6 are set as a threaded connection, so that when the operator rotates the threaded cylinder 7, the threaded cylinder 7 can move up and down along the adjusting screw 6.

[0027] Please see Figure 2 , Figure 3 and Figure 4Each threaded cylinder 7 has a support rod 8 rotatably connected to its inner wall. The support rod 8 is positioned on the inner wall of the threaded cylinder 7 and rotatably connected to limit its movement, allowing the support rod 8 to rise and fall with the threaded cylinder 7. A first flange 9 is fixedly connected to the bottom end of each support rod 8. Two H-beams 3 are located below the concrete roof slab 1. Two second flanges 11 are fixedly connected to the upper surface of each H-beam 3. Each second flange 11 is fixedly connected to its corresponding first flange 9 with equally spaced first fixing bolts 10. A guide rod 12 is fixedly connected to the inner bottom wall of each support rod 8. The outer surface of each guide rod 12 is slidably connected to the inner wall of its corresponding adjusting screw 6. The H-beams 3 are positioned below the concrete roof slab 1. Furthermore, a second flange 11 is installed on the upper surface of the H-beam main beam 3, and a first flange 9 is set at the bottom end of the support rod 8. The first flange 9 can be fixed to the second flange 11 by setting the first fixing bolts 10 arranged at equal intervals. In addition, a guide rod 12 is installed on the inner bottom wall of the support rod 8, and the guide rod 12 is set to slide connection with the adjusting screw 6. When the threaded cylinder 7 is connected to the adjusting screw 6 to achieve lifting and lowering, the support rod 8 will only lift and lower along the direction of the adjusting screw 6, without generating rotational force. This allows the device to achieve the lifting and lowering effect of the support rod 8 by the operator rotating the threaded cylinder 7, thereby enabling the corresponding H-beam main beam 3 to be lifted and lowered. This achieves the positioning and installation of the H-beam main beam 3, improves construction efficiency, and can adapt to the installation requirements of different building heights.

[0028] Example 2: A steel structure transfer layer, please refer to... Figure 2 , Figure 3 and Figure 5Two H-beam main beams 3 are fixedly connected to each other on their adjacent sides by connecting parts 13. A box-section secondary beam 14 is provided between the two H-beam main beams 3. The connecting parts 13 are installed on the adjacent sides of the H-beam main beams 3 to form a fixed connection, thereby fixing the connecting parts 13. The box-section secondary beam 14 is placed between the two H-beam main beams 3 and is set at a 90-degree angle to the H-beam main beams 3. Two third fixing bolts 19 are provided on the front and back of each connecting part 13. The third fixing bolts 19 are located at the connection position between the connecting part 13 and the box-section secondary beam 14. Each third fixing bolt 19 has a connecting plate 18 fixedly installed on its inner wall at equal intervals. Each connecting plate 18 is fixedly installed on the inner wall of the corresponding connecting part 13 and the box-section secondary beam 14. The connecting plate 18 is installed on the inner wall of the corresponding third fixing bolt 19 and fixed to the corresponding connecting part 13 and the box-section secondary beam 14, so that the third fixing bolt 19 and the connecting plate 18 can be connected to the corresponding connecting part 13 and the box-section secondary beam 14, so that the connecting part 13 and the box-section secondary beam 14 can be spliced. At this time, the H-shaped steel main beam 3, the connecting part 13 and the box-section secondary beam 14 form a steel beam frame.

[0029] Please see Figure 3 and Figure 5 An anti-slip grating tread 15 is provided on the upper surface of the box-section secondary beam 14. Connectors 16 arranged at equal intervals are fixedly connected to both the front and back of the anti-slip grating tread 15. The anti-slip grating tread 15 is located on the upper surface of the box-section secondary beam 14, and connectors 16 are provided on both the front and back of the anti-slip grating tread 15. The anti-slip grating tread 15 allows maintenance personnel to walk directly on it. A second fixing bolt 17 is fixedly installed on the inner wall of each connector 16. Each second fixing bolt 17 is fixedly installed to the box-section secondary beam 14. The second fixing bolt 17 is installed on the inner wall of the connector 16 for a fixed connection, and is connected to the box-section secondary beam 14, thereby allowing the connector 16 to be fixed to the upper flange of the box-section secondary beam 14, and thus allowing the anti-slip grating tread 15 to be installed on the upper flange of the box-section secondary beam 14.

[0030] Please see Figure 2 , Figure 3 and Figure 5Two horizontal bars 20 are provided above the box-section secondary beam 14. Each horizontal bar 20 has a bottom surface fixedly connected to a vertical bar 21 arranged at equal intervals. The bottom end of each vertical bar 21 is fixedly connected to the upper surface of the box-section secondary beam 14. By placing the horizontal bars 20 above the box-section secondary beam 14 and installing the vertical bars 21 arranged at equal intervals on the bottom surface of the horizontal bars 20, and fixing the bottom ends of the vertical bars 21 to the upper surface of the box-section secondary beam 14, the horizontal bars 20 and vertical bars 21 can be installed on the box-section secondary beam 14. On the upper surface of beam 14, there are connecting rods 22 arranged at equal intervals below each horizontal bar 20. The end of each connecting rod 22 is fixedly connected to the outer surface of the corresponding vertical bar 21. By placing the connecting rods 22 below the vertical bar 21 and fixing the ends of the connecting rods 22 to the corresponding vertical bar 21, the horizontal bars 20, vertical bars 21 and connecting rods 22 can form a guardrail and be fixed on the upper surface of the box-section secondary beam 14. When used together with the anti-slip grating pedal 15, it can improve the safety of operation and maintenance.

[0031] The implementation principle of this application embodiment is as follows: First, by connecting the chemical anchor 2 to the concrete top slab 1, the adjusting screw 6 and the support rod 8 are hoisted onto the bottom surface of the concrete top slab 1. Then, on the ground, the connecting part 13 and the box-section secondary beam 14 are connected by the connecting plate 18 and the third fixing bolt 19 to complete the assembly of the steel beam frame. Subsequently, the steel beam frame is hoisted as a whole by a tower crane. The first flange 9 and the second flange 11 are connected by the first fixing bolt 10, so that the steel beam frame is hoisted below the corresponding chemical anchor 2. At this time, by rotating the corresponding threaded cylinder 7, the threaded cylinder 7 can be connected to the adjusting screw 6. Through the sliding connection between the guide rod 12 and the adjusting screw 6, the support rod 8 can be raised together with the threaded cylinder 7. The H-beam is lowered to achieve leveling of the main H-beam 3, enabling its positioning and installation. This improves construction efficiency and adapts to installation requirements of different building heights. The connector 16 is installed on the upper surface of the box-section secondary beam 14 using the second fixing bolt 17, allowing the anti-slip grating tread 15 to be installed on the upper surface of the box-section secondary beam 14. The guardrail is installed by fixing the horizontal bar 20, vertical bar 21, and connecting bar 22, with the bottom end of the vertical bar 21 fixed to the upper surface of the box-section secondary beam 14. This allows the device to facilitate operator movement by setting the anti-slip grating tread 15, and the guardrail, when used in conjunction with the anti-slip grating tread 15, enhances operational safety.
