Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a climbing frame pull rod fixing structure and a fixing method thereof. Background Art

[0002] With the continuous development of super-high-rise structures, the requirements for construction progress and construction safety are also increasing. In the traditional flower stand construction, cantilever scaffolding is generally used as the operating frame. Because the flower stand is high above the ground, it is an extremely dangerous high-altitude operation, the frame is difficult to erect, and the scaffolding construction is difficult and time-consuming, which has a great impact on the construction progress of the main structure of the entire project. In addition, the cantilever scaffolding takes a long time to erect and requires a lot of manpower, which greatly increases the cost. At the same time, the construction of the cantilever scaffolding of the flower stand is a high-altitude operation, with a high risk factor and low erection efficiency, which further increases the erection time and thus increases the cost.

[0003] According to the characteristics of the flower stand structure that the floor height and structural form are inconsistent with the standard floor, especially the high height of the flower stand, the reduced column cross-section, and the outer shear wall ending at the roof, there is a problem that the climbing frame cannot be attached.

[0004] Therefore, in order to solve the problem of slow overall construction progress and high construction cost caused by traditional cantilever scaffolding, a fixing structure and fixing method of the climbing frame for the construction of non-standard structures such as flower stands were proposed to carry out the construction of roof structures such as flower stands, so as to ensure that the overall construction progress of the project is completed ahead of schedule and solve the problem of climbing frame attachment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a climbing frame pull rod fixing structure and a fixing method thereof, which solves the problem that in traditional flower stand construction, a cantilever scaffolding is generally used as an operating frame. Because the flower stand is high above the ground, it belongs to an ultra-dangerous high-altitude operation, the frame is difficult to erect, and the scaffolding construction is difficult and time-consuming. According to the characteristics of the flower stand structure that the floor height and structural form are inconsistent with the standard floor, especially the flower stand height is high, the column cross-section is reduced, and the outer shear wall has been terminated on the roof, there is a problem that the climbing frame cannot be attached.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a climbing frame pull rod fixing structure, including a fixed pull rod, wherein both ends of the fixed pull rod are provided with a beam-slab structure and a climbing frame main body, and an embedded sleeve is embedded when the beam-slab structure is cast, and a fixing bolt is threadedly connected to the inner wall of the embedded sleeve, and an angle code is installed on the top of the fixing bolt, and the two ends of the fixed pull rod are respectively connected to the climbing frame main body and the angle code through a pin shaft.

[0007] Preferably, the fixed pull rod comprises:

[0008] Adjustment sleeve;

[0009] Two fixing rods are respectively arranged at two ends of the adjusting sleeve, and the ends of the fixing rods are fixedly connected with screw rods, the screw rods are inserted into the inner wall of the adjusting sleeve, and the ends of the adjusting sleeves are rotatably provided with adjusting nuts, which are threadedly connected with the screw rods.

[0010] Preferably, the top end of the fixing bolt is threadedly connected to two fixing nuts, and the two fixing nuts are tightly against each other.

[0011] Preferably, a gasket is sleeved on the outer side of the fixing bolt, and two sides of the gasket are tightly against the nut and the angle bracket respectively.

[0012] A method for fixing a climbing frame pull rod fixing structure, the fixing method comprising the following steps:

[0013] Step 1: Tie the steel bars of the roof beams and slabs;

[0014] Step 2: Locate and locate the position of the embedded sleeve on the beam and slab reinforcement according to the position of the climbing frame main body and the layout of the fixed pull rod;

[0015] Step 3: pouring roof concrete to form a beam-slab structure;

[0016] Step 4: The main body of the climbing frame is climbed, and the fixed pull rod with the angle code is fixed with fixing bolts and embedded sleeves;

[0017] Step 5: Adjust the length of the fixed tie rod by adjusting the nut to ensure stable force;

[0018] Step 6: At this time, the main body of the climbing frame can be used to construct the flower stand and other roof structures;

[0019] Step 7: After the construction is completed, the main body of the climbing frame is dismantled, the embedded sleeve is cut off, and the hole in the embedded sleeve is filled.

[0020] Preferably, the embedded sleeve is fixed to the beam and slab reinforcement by welding via reinforcing ribs.

[0021] Preferably, the height of the embedded sleeve from the bottom of the beam-slab structure is greater than or equal to 25 mm.

[0022] Preferably, the embedded sleeve is coated with adhesive tape before pouring the roof concrete.

[0023] The present invention discloses a climbing frame pull rod fixing structure and a fixing method thereof, which have the following beneficial effects:

[0024] 1. The fixing structure and fixing method of the climbing frame tie rod fix the fixing tie rod through the embedded sleeve, which solves the problem that the main body of the climbing frame is difficult to attach to the roof structure such as the flower stand. The embedded sleeve is fixed by welding with the beam and slab steel bars in the beam and slab structure through additional steel bars, which ensures the accuracy of the attachment point of the main body of the climbing frame, solves the problems of difficult erection, difficult dismantling and high risk factor of scaffolding in the construction operation of the roof structure such as the flower stand, avoids the long rental time and large labor consumption of traditional cantilever scaffolding materials, and reduces construction costs. Compared with the traditional cantilever scaffolding, it is necessary to open holes in vertical structures such as parapets to destroy the concrete structure and increase the risk of leakage in the later stage. The main body of the climbing frame is fixed by connecting the embedded sleeve with the fixed tie rod, which further ensures the construction quality of the roof. Thereby, the construction efficiency can be improved and the construction period can be accelerated.

[0025] 2. The fixing structure and fixing method of the climbing frame tie rod are to embed a sleeve 4 in the concrete structure of the roof to connect the fixing tie rod. The normal climbing of the climbing frame body does not affect the construction progress of the flower stand, and the fixing tie rod can be quickly fixed by connecting with the embedded sleeve after the climbing frame body is lifted. The embedded sleeve and the beam and slab steel bars are welded and fixed by reinforcing bars. The height of the embedded sleeve from the bottom of the beam and slab structure is greater than or equal to 25mm, ensuring that the thickness of the steel bar protective layer meets the requirements, greatly reducing the risk of leakage of the concrete roof. The embedded sleeve is embedded in advance, which also avoids the damage to the structure caused by the later embedded parts, improves the construction efficiency and reduces the cost.

[0026] 3. The climbing frame pull rod fixing structure and fixing method require the pre-embedded sleeve to be pre-embedded during the roof beam and slab reinforcement binding construction stage, and the pre-embedded sleeve shall be wrapped with tape before the roof concrete is poured to avoid concrete clogging. After the concrete structure of the beam and slab structure is poured, the outer tape of the pre-embedded sleeve shall be cleaned and the climbing frame body shall be climbed.

[0027] 4. The climbing frame tie rod fixing structure and fixing method thereof ensure a more secure connection between the two fixing nuts and the fixing bolts by tightly abutting against each other. This design prevents the fixing tie rod from loosening or falling off due to excessive force during use. Since the two fixing nuts are pressed against each other, they constrain each other to prevent loosening due to vibration or external force. This design improves the reliability and safety of the climbing frame fixing device. When the position or height of the climbing frame needs to be adjusted, the tightness of the fixing bolts can be easily adjusted by rotating the fixing nuts. This design makes the fixing and adjustment of the fixing tie rod more flexible and convenient.

[0028] 5. In the fixing structure and fixing method of the climbing frame tie rod, the gasket is located between the nut and the angle bracket, and by increasing the contact area, the pressure exerted by the nut on the angle bracket can be more effectively dispersed. This helps to ensure a tighter connection and reduce loosening or damage caused by excessive local pressure. When the fixing bolt is subjected to tension or pressure, the gasket can disperse these stresses and prevent stress from concentrating on a small area of ​​the connecting component. This helps to increase the reliability and durability of the connection. The gasket can reduce friction and wear between the nut and the angle bracket. This helps to protect the surface of the connecting component and extend its service life. And the presence of the gasket provides an additional supporting surface between the nut and the angle bracket. This helps to ensure that the surface of the angle bracket is not damaged due to excessive force during the tightening process. BRIEF DESCRIPTION OF THE DRAWINGS

The embedded sleeve 4 is fixed by welding with the beam and slab steel bars in the beam and slab structure 2 through additional steel bars, which ensures the accuracy of the attachment point of the climbing frame main body 3, and solves the problems of difficult erection, difficult dismantling and high risk factor of scaffolding construction operations such as flower stands. It avoids the long rental time and large labor consumption of traditional cantilever scaffolding materials, and reduces construction costs. Compared with the traditional cantilever scaffolding, it is necessary to open holes in vertical structures such as parapets to destroy the concrete structure and increase the risk of leakage in the later stage. The fixed climbing frame main body 3 is connected to the fixed rod 1 by the embedded sleeve 4, which further ensures the construction quality of the roof. Thereby, the construction efficiency can be improved and the construction period can be accelerated.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The embodiment of the present invention discloses a climbing frame pull rod fixing structure. Figure 1-3 As shown, it includes a fixed pull rod 1, and a beam-slab structure 2 and a climbing frame main body 3 are arranged at both ends of the fixed pull rod 1.

The two ends of the fixed pull rod 1 are respectively connected to the climbing frame main body 3 and the angle code 6 through a pin shaft.

[0039] The fixed rod 1 is fixed by the embedded sleeve 4, which solves the problem of the difficulty of the climbing frame main body 3 to attach to the roof structure such as the flower stand.

It avoids the long rental time and large labor consumption of traditional cantilever scaffolding materials, and reduces construction costs. Compared with the traditional cantilever scaffolding, it is necessary to open holes in vertical structures such as parapets to destroy the concrete structure and increase the risk of leakage in the later stage. The fixed climbing frame main body 3 is connected to the fixed rod 1 by the embedded sleeve 4, which further ensures the construction quality of the roof.

[0043] It is particularly disclosed that the top end of the fixing bolt 5 is threadedly connected with two fixing nuts, and the two fixing nuts are tightly against each other.

[0044] The fixing nut is a fastener used in conjunction with the fixing bolt 5.

[0045] The two fixing nuts are tightly against each other, ensuring a stronger connection between them and the fixing bolt 5. This design prevents the fixing rod 1 from loosening or falling off due to excessive force during use. Because the two fixing nuts are tightly against each other, they constrain each other to prevent loosening due to vibration or external force. This design improves the reliability and safety of the climbing frame fixing device. When the position or height of the climbing frame needs to be adjusted, the tightness of the fixing bolt 5 can be easily adjusted by rotating the fixing nut. This design makes the fixing and adjustment of the fixing rod 1 more flexible and convenient.

[0046] It is particularly disclosed that a gasket is sleeved on the outer side of the fixing bolt 5, and two sides of the gasket are tightly against the nut and the angle code 6 respectively.

[0047] The washer is located between the nut and the angle bracket 6, and by increasing the contact area, it is able to more effectively disperse the pressure exerted by the nut on the angle bracket 6. This helps to ensure a tighter connection and reduce loosening or damage caused by excessive local pressure. When the fixing bolt 5 is subjected to tension or pressure, the washer can disperse these stresses and prevent stress from concentrating on a small area of ​​the connected component. This helps to increase the reliability and durability of the connection. The washer can reduce friction and wear between the nut and the angle bracket 6. This helps to protect the surface of the connected component and extend its service life. And the presence of the washer provides an additional supporting surface between the nut and the angle bracket 6. This helps to ensure that the nut will not damage the surface of the angle bracket 6 due to excessive force during the tightening process.
