Description

Technical Field

[0001] The utility model relates to the field of engineering construction, in particular to an anti-corrosion scaffold connecting member for tie bolts. Background Art

[0002] During the construction of large pool walls and other projects, the stability requirements for the installation of scaffolds are extremely high. For the design of scaffold connecting members, the simplest and most reliable traditional method is to directly embed steel pipes in the concrete pool wall, use the part of the steel pipe protruding from the pool wall as the connecting member, and fixedly connect it with the scaffold through rotating fasteners. See Figure 3 . Then the project construction is carried out. After the project construction is completed, the steel pipe protruding from the surface of the pool wall needs to be cut off, and the inside of the steel pipe embedded in the pool wall is grouted with a prepared slightly expanding cement grouting material or filled with fine aggregate concrete, and then manually tamped and the concrete is cured.

[0003] However, in the traditional method, it is not easy to vibrate the inside of the steel pipe densely. Over time, it will form a weak part of the pool wall, affecting the overall stability of the pool wall structure, and there are also defects such as complex structure, cumbersome construction, time-consuming and laborious. If it is a garbage pool, after the garbage pool is built and put into production, due to the mixed fermentation of various garbage, the corrosion of the pool wall is very strong. The traditional method will seriously affect the anti-corrosion performance of the pool wall, resulting in a very difficult and thorny problem for the later repair of the pool wall. Therefore, it is not suitable to set the scaffold connecting member in the garbage pool according to the conventional traditional method. In engineering practice, many scholars consider the economic practicality of the connecting member, and constantly pursue simple structure, convenient material selection, easy installation and removal. On the basis of the traditional rigid connecting member, it is necessary to develop a new type of connecting member structure with long-term corrosion resistance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-corrosion scaffold connecting member for tie bolts and its construction application method, which is used to solve the problems that it is not easy to vibrate the inside of the steel pipe of the traditional connecting member densely, which will form a weak part of the pool wall over time, affecting the overall stability of the pool wall structure, and the later anti-corrosion performance.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is: an anti-corrosion scaffold connecting member for tie bolts, including a connecting member, the connecting member is composed of a tie bolt, a butterfly clip nut, a positioning pipe and a connecting pipe. The tie bolt is embedded in the pool wall, the front end of the tie bolt extends outside the pool wall, the positioning pipe is sleeved on the front end of the tie bolt, and the butterfly clip nut is clamped and fixed on the pool wall. The two ends of the connecting pipe are respectively fixedly connected with the scaffold and the positioning pipe through fasteners.

[0006] Preferably, the tie bolt adopts a high-strength water-stop bolt with a water-stop piece in the middle, and its diameter is 14mm.

[0007] Preferably, the diameter of the butterfly clip nut is larger than the diameter of the positioning pipe.

[0008] Preferably, the length of the positioning pipe is 100 mm shorter than the length of the front-end extension part of the tie bolt.

[0009] A tie bolt anti-corrosion scaffold wall connecting member and its construction application method are as follows.

[0010] First, install the formworks on both sides of the pool wall and embed the tie bolts. Use the butterfly clip nuts to fasten the positioning pipes to the side of the formworks, and use fasteners to connect the two ends of the connecting pipes to the positioning pipes and the scaffold respectively.

[0011] Secondly, carry out the pouring and curing of the pool wall on the scaffold.

[0012] Then, after the pool wall concrete reaches the designed strength through curing, remove the formworks of the pool wall from top to bottom. Leave the tie bolts at intervals of 2 steps and 3 spans, and cut off the tie bolts at the remaining positions in advance. For the tie bolts left after the formwork removal, clamp them with the butterfly clip nuts to fix the positioning pipes on the pool wall.

[0013] Finally, after the subsequent construction of the pool wall is completed, remove the scaffold and carry out anti-corrosion treatment on the tie bolt parts, and the construction is completed.

[0014] Preferably, the process of anti-corrosion treatment on the tie bolt parts is as follows.

[0015] First, roughen the periphery of the screw rod.

[0016] Secondly, cut off the remaining tie bolts.

[0017] Then, apply antirust paint to the end of the tie bolt.

[0019] Then, apply cement slurry and mortar for leveling.

[0020] Finally, carry out curing.

[0021] Preferably, the wall connecting members are arranged in a diamond shape or a rectangular shape on the pool wall.

[0022] Compared with the prior art, the advantages of the present utility model are as follows:

[0023] (1) When pouring the garbage pool wall, the formworks on both sides of the present utility model are reinforced with tie bolts.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] A tie bolt anti-corrosion scaffolding wall connecting member, refer to Figure 1 and Figure 2, including the wall connecting member 3, which is composed of the tension bolt 4, the butterfly clip nut 7, the positioning pipe 5 and the connecting pipe 6. The tension bolt 4 is embedded in the pool wall 1, and the front end of the tension bolt 4 extends outside the pool wall 1. The positioning pipe 5 is sleeved on the front end of the tension bolt 4, and the butterfly clip nut 7 is clamped and fixed on the pool wall 1. Both ends of the connecting pipe 6 are fixedly connected to the scaffolding 2 and the positioning pipe 5 respectively through fasteners 8. In the utility model, the positioning pipe 5 is used as the connecting part and is fixed on the pool wall 1 by using the tension bolt 4 and the butterfly clip nut 7. Since only the tension bolt 4 is embedded inside, only a solid screw rod will be left in the wall after cutting, and there is no need for internal pouring, and only surface anti-corrosion treatment is required. Moreover, during the formwork reinforcement process of the pool wall 1, the tension bolt 4 also needs to be reinforced, and no additional process will be added to the existing pouring construction process. Moreover, the tension bolt 4 and the pipe fittings are common materials on the construction site and are very easy to find, which is beneficial to the popularization and implementation of this technology. The utility model saves materials through the multi-functional utilization of the tension bolt 4 material, and has good anti-corrosion, waterproof and anti-seepage performance; fast installation speed, time saving; simple treatment method, low treatment cost and short treatment time; cost reduction and efficiency increase, accelerating the construction speed, safe and reliable.

[0031] The tension bolt 4 adopts a high-strength water-stop bolt with a water-stop piece in the middle, and its diameter is 14 mm, which can prevent water leakage after the cracks around the tension bolt 4 and the wall.

[0032] The diameter of the butterfly clip nut 7 is larger than the diameter of the positioning pipe 5, which is beneficial to clamping and fixing the positioning pipe 5 by the butterfly clip nut 7 during the tightening process. The length of the positioning pipe 5 is 100 mm shorter than the length of the extended part of the front end of the tension bolt 4, which is convenient for the installation and fixation of the butterfly clip nut 7 and the positioning pipe 5.

[0033] A tension bolt 4 anti-corrosion scaffolding 2 wall connecting member 3 and its construction application method, the method steps are as follows.

[0034] First, install the formwork on both sides of the pool wall 1 and embed the tension bolt 4. Use the butterfly clip nut 7 to fasten the positioning pipe 5 to the side of the formwork, and use the fastener 8 to connect both ends of the connecting pipe 6 to the positioning pipe 5 and the scaffolding 2 respectively.

[0035] Secondly, carry out the pouring and curing of the pool wall 1 on the scaffolding 2.

[0036] Then, after the concrete of the pool wall 1 reaches the design strength after curing, remove the formwork of the pool wall 1 from top to bottom. According to the specifications and the external frame plan, the spacing of the tension bolts 4 is left at a spacing of 2 steps and 3 spans, and the tension bolts 4 at the remaining positions are cut off in advance. For the tension bolts 4 left after the formwork is removed, clamp them through the butterfly clip nuts 7 to fix the positioning pipe 5 on the pool wall 1.

[0037] Finally, after the construction of the pool wall 1 in the later stage, the scaffolding 2 is removed and the anti-corrosion treatment is carried out on the part of the tie bolts 4, and the construction is completed.

[0038] (1) The process of anti-corrosion treatment for the part of the tie bolts 4 is as follows.

[0039] First, roughen the area around the screw rod; after roughening, the applied cement slurry can fit more closely to the pool wall 1 and is not easy to fall off.

[0040] Secondly, cut off the remaining tie bolts 4.

[0041] Then, apply anti-rust paint to the ends of the tie bolts 4. Applying anti-rust paint to their ends can effectively prevent the tie bolts 4 remaining in the pool wall 1 from being corroded and rusted.

[0042] Then, water it to make it wet. Watering makes it wet and is convenient for the cement slurry to fit.

[0043] Then, apply cement slurry and mortar for leveling.

[0044] Finally, carry out maintenance to achieve anti-corrosion treatment for the part of the tie bolts 4 and surface finishing of the pool wall 1.

[0045] (2) Requirements for the erection of the scaffolding 2:

[0046] (1) The connecting members 3 should be rigid members that can bear tensile and compressive loads, and should be firmly connected to the main structure of the building and the scaffolding 2 frame body.

[0047] (2) The connecting members 3 should be arranged close to the socket nodes of the horizontal bars of the scaffolding 2.

[0048] (3) The connecting members 3 on the same layer should preferably be on the same horizontal plane, with a horizontal spacing of 2 spans and a vertical spacing of 2 steps; the cantilever height of the frame body above the connecting members 3 should not exceed 2 steps.

[0049] (4) Connecting members 3 should be added at the corners of the frame body, and the vertical spacing of the connecting members 3 should not be greater than 4m.

[0050] (5) The connecting members 3 should preferably start from the first horizontal bar at the bottom layer.

[0051] (6) The connecting members 3 should preferably be arranged in a diamond shape, or can also be arranged in a rectangle; the connecting points should be evenly distributed.

[0052] (7) When the connecting members 3 cannot be erected at the lower part of the scaffolding 2, it is advisable to expand and erect multiple rows of scaffolding 2 and set inclined bars to form an additional trapezoidal frame in the shape of an outer inclined plane.

[0053] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
