[0061] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0062] Embodiment 1

[0063] See also Figure 1 and Figure 2The embodiment of the present application provides a steel column for attaching a climbing frame of a roof frame layer, including a column 1, a diagonal brace column 3, a bottom column 2, a guide assembly, two ropes 4 and a wall support 6. The column 1, the bottom column 2 and the diagonal brace column 3 enclose a first triangular structure. In a mechanical structure, a triangular structure can provide a stable force system. Specifically, the column 1 and the bottom column 2 can be detachably fixed to the roof frame layer 5, the bottom column 2 is vertically connected to the column 1, and the two ends of the diagonal brace column 3 are respectively connected to the column 1 and the bottom column 2. A wall-mounted support 6 is detachably connected to the column 1, and a climbing frame (not shown in the figure) is installed on one side of the wall-mounted support 6. An electric hoist or a hydraulic cylinder is used as a power to enable the climbing frame to rise or fall. Here, the detachable connection method can be a bolt connection method, which is convenient, fast and reliable, and preferably high-strength bolts are used for fixed connection, so that the connection between the wall-mounted support 6 and the column 1 is more firm and reliable, and the integrity and rigidity of the connection are improved, ensuring that the wall-mounted support 6 can withstand the force generated by the climbing frame and transmit it to the column 1. When installing the wall-mounted support 6, care should be taken to fully stick the wall-mounted support 6 to the plane of the column 1 to prevent the wall-mounted support 6 from loosening. At the same time, a guide assembly is connected to the column 1, and the guide assembly can adjust the angle between it and the column 1; two ropes 4 are symmetrically arranged on both sides of the column 1, wherein one end of the rope 4 is hinged to the column 1, and the other end is detachably connected to the roof frame layer 5, and the rope 4 abuts against the guide assembly, and can produce synchronous angle changes with the guide assembly, that is, when the guide assembly changes the angle between it and the column 1, it drives the rope 4 to rotate around the column 1, thereby changing the angle between the rope 4 and the column 1, and making the angle between the rope 4 and the column 1 on both sides of the column 1 consistent. Here, the rope 4 preferably uses a high-strength rope 4, such as a steel wire rope, a cable, etc.

[0064] From the perspective of force analysis, see Figure 1 The columns 1, the ropes 4 and the roof frame layer 5 form a second triangular structure, see Figure 2, and are perpendicular to the action surface of the first triangular structure, that is, the attached steel column can present a triangular force-stable structure from two different planes, thereby ensuring the stability of the attached steel column. At the same time, the angle between the rope 4 and the column 1 is adjusted by the guide assembly to make it at the optimal force angle. The optimal force angle refers to the angle at which the triangle can withstand the maximum force under the force, and the angle between the rope 4 and the column 1 on both sides of the column 1 is always consistent, so that the forces on both sides of the column 1 are consistent and the forces are stable. Therefore, the attached steel column can be used as a stable attachment point and support point for the climbing frame, which solves the problem that the climbing frame cannot be attached at super-high floor heights, ensures safety and stability during the lifting process of the climbing frame, and greatly speeds up the construction speed; avoids a large number of high-altitude operations in setting up traditional cantilever scaffolding, greatly reduces safety risks, has high safety, and saves time for setting up and dismantling traditional cantilever scaffolding and pre-buried cantilever I-beams, saving construction period; at the same time, the attached steel column uses less material, requires fewer staff, and saves construction costs.

[0065] In a specific embodiment, see Figure 1 to Figure 2 , the first triangular structure is formed by the vertical column 1, the bottom column 2 and the diagonal support column 3. The vertical column 1 includes a bottom steel plate (not shown in the figure), a top steel plate 101, a plurality of first connecting plates 102 and at least two vertically arranged first support columns 103. Here, the first support column 103 can be made of materials such as steel sections, channel steels, I-beams, etc. in the prior art that can provide high strength and good rigidity. The high strength performance can ensure that it can withstand a large load, and the good rigidity ensures that it is not easy to deform when subjected to force, thereby ensuring the stability of the structure. There is no limitation on the specific number of the first support columns 103, as long as it can provide a stable climbing frame attachment point and keep the first support column 103 structure symmetrical. See. Figure 3 It is preferred to use at least two first support columns 103 because when the first support column 103 is made of a material with an asymmetric cross-section such as channel steel, in order to ensure that the force is uniform, two first support columns 103 should be arranged relatively to each other so that the overall structure is symmetrical and the force is uniform. The first support columns 103 are connected by a plurality of first connecting plates 102 arranged at intervals. The bottom and top ends of the first support columns 103 are connected to the bottom steel plate and the top steel plate 101 respectively. The first connecting plates 102, the bottom steel plate and the top steel plate 101 form a plurality of first support columns 103 into a whole, thereby ensuring the structural stability of the column 1 and the reliability of the connection between the wall support 6 and the column 1. Figure 3 The first connecting plate 102 can be arranged in such a manner that: a vertical first connecting plate 102 is symmetrically arranged between two first connecting plates 102, and a plurality of first connecting plates 102 are arranged at intervals in the vertical direction. The first connecting plate 102 is connected to the wall support 6, the rope 4 is hinged to the first support column 103, and the bottom steel plate is detachably connected to the roof frame layer 5.

[0066] In other embodiments, the first connecting plate may also be disposed in the following manner: the first connecting plate is disposed in a "Z" shape between two first supporting columns, and two adjacent first connecting plates and the first supporting columns form a triangle.

[0067] See also Figure 2 and Figure 4 , the bottom column 2 includes at least two horizontally arranged second support columns 201 and a second connecting plate 202. Here, the material of the second support column 201 is not limited, as long as it can ensure high strength and good rigidity. At the same time, the specific number of the second support column 201 is not limited, as long as the structural symmetry of the second support column 201 can be achieved. The reason for preferably using at least two second support columns 201 can refer to the above explanation of the number of the first support column 103, which will not be repeated here. The two ends of the second support column 201 are respectively connected by the second connecting plate 202, so that the second support column 201 forms a whole. The bottom end of the second support column 201 is detachably connected to the roof frame layer 5, and one of the second connecting plates 202 is abutted against the first support column 103 or the first connecting plate 102 (when the first support column 103 is provided with a first connecting plate 102 at the bottom), and can be connected by welding, so that the bottom column 2 is fixedly connected to the column 1.

[0068] See also Figure 2 and Figure 5 One end of the diagonal brace column 3 is connected to the second support column 201, and the other end of the diagonal brace column 3 is connected to the top steel plate 101, which can be connected by welding. The angle between the diagonal brace column 3 and the horizontal plane of the roof frame layer 5 is 45° to 60°.

[0069] In a specific embodiment, a plurality of bolt sleeves are embedded in the roof frame layer 5, and a plurality of bolt holes are provided on the bottom steel plate and the second support column 201. The bottom steel plate and the second support column 201 are detachably connected to the roof frame layer 5 through threaded connection between the bolts and the bolt sleeves. High-strength bolts are preferably used as the bolts. The detachable bolt connection makes installation and disassembly more convenient, which can speed up the construction speed and shorten the construction period.

[0070] In a specific embodiment, see Figure 1 and Figure 6The guide assembly includes two guide rods 7, a telescopic rod and two connecting rods 8. The telescopic rod includes an outer tube 9 and a sliding rod 10. The outer tube 9 is fixedly connected to the first connecting plate 102 or the first supporting column 103. The sliding rod 10 extends into the outer tube 9 and can slide along the outer tube 9 in the vertical direction. The sliding rod 10 and the outer tube 9 are respectively provided with a plurality of positioning holes 11. The outer tube 9 and the sliding rod 10 are detachably connected by positioning bolts 12, wherein the positioning bolts 12 penetrate the positioning holes 11. Here, the number of positioning bolts 12 is not limited, as long as they can fix the sliding rod 10 and prevent it from moving. Due to the outer tube 9, the sliding rod 10 and the diagonal support column 3 (in order to better present the positional relationship between the guide assembly and the column 1, Figure 1 The diagonal support column 3 and the bottom column 2 are not shown in the figure. They are arranged on the same side of the first support column 103. The setting height of the outer tube 9 and the sliding rod 10 should ensure that the sliding rod 10 is not affected by the diagonal support column 3 when sliding. The two guide rods 7 are arranged vertically symmetrically and hinged to the first support column 103. The guide rods 7 are provided with empty slots for the rope 4 to pass through. The two connecting rods 8 are arranged vertically symmetrically and one end is connected to the sliding rod 10. The other ends of the two connecting rods 8 are hinged to the two guide rods 7 respectively.

[0071] When using, refer to Figure 1 and Figure 6 , by driving the sliding rod 10 to slide along the outer cylinder 9 in the vertical direction, the connecting rod 8 is driven to move, and the guide rod 7 is driven to rotate around the first support column 103. Since the rope 4 passes through the guide rod 7 and abuts against it, the guide rod 7 will drive the rope 4 to rotate synchronously when rotating, thereby achieving the purpose of adjusting the angle between the rope 4 and the first support column 103, so that it is at the best force angle, and the bearing capacity is provided to the first support column 103 to the maximum extent. In addition, since the two ropes 4, the two guide rods 7 and the two connecting rods 8 are symmetrically arranged about the vertical central axis of the first support column 103, it is ensured that the ropes 4 on both sides of the first support column 103 are always consistent with the angle of the first support column 103, so that the pulling force provided by the ropes 4 on both sides of the first support column 103 is consistent in direction, and since the two ropes 4 are made of the same material, the magnitude of the pulling force provided by the two ropes is also consistent, and the bearing capacity provided to the first support column 103 is consistent, thereby ensuring that the forces on both sides of the first support column 103 are consistent, and maintaining its force stability.

[0072] Embodiment 2

[0073] Based on the same invention concept, a roof frame climbing system is proposed, see Figure 7The climbing system includes a climbing frame rail 13, a climbing frame 14 and the attached steel column in Example 1. The wall-attached support 6 is arranged on the upper part of the column 1, and the wall-attached support 6 is provided with a climbing frame rail 13, and the climbing frame 14 is slidably arranged on the wall-attached support 6 through the climbing frame rail 13. When in use, the attached steel column can provide an attachment point and a support point for the climbing frame, and under the action of the driving device 15, the climbing frame 14 can climb along the climbing frame rail 13. Here, the driving device 15 can adopt an electric hoist and a hydraulic cylinder in the prior art. Through this climbing system, it can be achieved that the climbing frame can still work normally in some higher roof frame layer areas, and a large amount of high-altitude operations in setting up traditional cantilever scaffolding can be avoided, which greatly reduces the safety risk, has high safety, and saves the time for setting up and dismantling traditional cantilever scaffolding and pre-embedded cantilever I-beams, saving construction period.

[0074] Embodiment 3

[0075] Based on the same inventive concept, a construction method of a roof frame layer climbing system is proposed, using the climbing system of the second embodiment, referring to Figure 8 , specifically including the following steps:

[0076] S1. Arrange and fix steel bars on the roof frame layer, and add reinforcing bars at the preset positions of the columns and base columns.

[0077] In step S1, by adding reinforcing bars, the tensile properties and bearing capacity of concrete can be increased, so that the bearing capacity of the columns and base columns can be guaranteed. The specifications of the reinforcing bars should meet the requirements of the climbing frame attachment tension. The reinforcing bars can be set as follows: using steel bars with a nominal diameter of 16mm and a length of 2000mm, arranged at intervals in the horizontal and vertical directions, with an arrangement spacing of 200mm. After the steel bars are fixed, the diameter, spacing and length of the steel bars should be checked to see if they meet the design requirements. Subsequent steps can be carried out only after acceptance.

[0078] S2. According to the preset positions of the columns and base columns, determine and mark the positions of the bolt sleeves, and fix the bolt sleeves on the steel bars.

[0079] In step S2, the following steps are specifically included: bolt holes are set at the bottom ends of the columns and the bottom columns, the positions of the bolt sleeves are marked according to the positions of the bolt holes, the positions of the bolt sleeves are checked again, and the bolt sleeves can be installed only after they are confirmed to be correct, and the bolt sleeves are fixed to the steel bars with a tie wire, and after the bolt sleeves are fixed, the positions of the bolt sleeves should be checked again, and each bolt sleeve is ensured to be vertically set, so that the columns and the bottom columns can be installed normally. Concrete pouring can only be carried out after the bolt sleeve positions are checked to be correct.

[0080] S3. Pour concrete. After the concrete pouring is completed and its strength reaches the design requirements, fix the columns and base columns by bolts and bolt sleeves, weld the contact parts between the columns, base columns and diagonal bracing columns, and make the columns, base columns and diagonal bracing columns enclose to form a triangle.

[0081] In step S3, the following steps are specifically included: transporting the mixed concrete to the roof, pouring the concrete, and using vibration to evenly distribute the concrete during pouring. During pouring, care should be taken to cover the bolt sleeves, and a diaphragm can be tied on the bolt sleeves to prevent concrete from entering the bolt sleeves and causing blockage. After pouring the concrete, it is maintained. The concrete hardening process will generate hydration heat. Sprinkling water to cool down the concrete surface can be used to ensure a constant temperature on the concrete surface and to control the humidity above 50%. After the strength of the concrete reaches the design requirements (greater than or equal to 75% of the design strength), the columns and base columns are placed in preset positions, and bolts are added to the bolt holes and tightened with the bolt sleeves to fix the columns and base columns, and the contact parts of the columns and base columns are welded, and the two ends of the diagonal brace columns are respectively welded to the columns and base columns, so that the columns, base columns and diagonal brace columns enclose a triangle.

[0082] S4. Install a guide assembly on the upper part of the column, and hinge one end of the rope to both sides of the column. The rope abuts against the guide assembly, and the other end is connected to the roof frame layer.

[0083] In step S4, the structure of the guide assembly can refer to the first embodiment. Specifically, the guide assembly includes two guide rods, a telescopic rod and two connecting rods. The telescopic rod includes an outer tube and a sliding rod. The outer tube is fixedly connected to the column. The sliding rod extends into the outer tube and can slide along the outer tube in the vertical direction. The sliding rod and the outer tube are respectively provided with a plurality of positioning holes. Before step S3 fixes the position of the column, the outer tube is pre-installed on the column. Then, two ropes are hinged to both sides of the column, two guide rods are hinged to both sides of the column, and the two ropes are respectively passed through the guide rods, the connecting rod is hinged on the guide rod, the sliding rod is sleeved in the outer tube, and the connecting rod is welded to the sliding rod, the sliding rod is adjusted to a suitable position (the angle between the rope and the column is at the best stress angle), the position of the sliding rod is fixed by passing the positioning bolt through the positioning hole, and the other end of the rope is fixed to the roof frame layer by anchor bolts or anchor nails.

[0084] S5. Install the wall-mounted support on the upper part of the column, and install the climbing frame guide rail and climbing frame.
