Description

Technical Field

[0001] This utility model relates to the field of thickness maintaining devices, specifically a device for maintaining the thickness of the protective layer of steel reinforcement in slipform construction of heat-absorbing tower walls. Background Technology

[0002] Slipform construction is a concrete casting process that uses a formwork device that can slide along the surface of poured concrete to continuously form a structure. In the construction of the wall of a heat-absorbing tower, this technology uses a slipform machine or manual labor to move the formwork, separating the concrete component from the formwork, thereby achieving the purpose of forming. Specifically, it involves assembling lateral formwork and an operating platform with a height of 0.9 to 1.4 meters on the ground according to the planar and vertical dimensions of the structure. The platform is then lifted by a lifting machine that crawls on support rods to carry out cyclical operations of rebar tying, concrete pouring, and formwork lifting, in order to realize the construction of tall structures.

[0003] In the current slipform construction of the heat absorption tower wall, the lack of precise and effective control methods means that the distance between the circumferential reinforcement and the formwork is not limited. This not only directly affects the durability and load-bearing capacity of the concrete structure, but also accelerates the corrosion process of the reinforcement due to inconsistent protective layer thickness, thereby weakening the structural safety performance. At the same time, in order to correct these deviations, frequent adjustments must be made during construction, which not only significantly increases the construction difficulty and cost, but also seriously reduces the overall construction efficiency. More seriously, whether the protective layer thickness is insufficient or excessive, it may become a potential hazard to structural safety. For example, the former may cause the reinforcement to corrode and expand, thereby damaging the concrete protective layer; the latter will lead to the waste of concrete materials and add unnecessary weight burden to the structure, further affecting the stability and safety of the structure. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a device for maintaining the thickness of the protective layer of reinforcing bars in the slipform construction of the wall of a heat-absorbing tower, so as to solve the technical problem that the distance between the circumferential reinforcing bars and the formwork is not accurately controlled in the slipform construction of the wall of a heat-absorbing tower, resulting in uneven protective layer thickness, which in turn affects the durability and load-bearing capacity of the concrete structure, increases the construction difficulty and cost, and may cause structural safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for maintaining the thickness of the protective layer of steel reinforcement in slipform construction of a heat-absorbing tower wall, comprising a holding device, wherein the holding device comprises a first piece and a second piece, the first piece and the second piece being integrally formed, and the first piece and the second piece being arranged at right angles;

[0006] The top of the first piece is provided with a curved plate, the inner side of the curved plate is formed with a mounting groove, the bottom of the curved plate is provided with a snap-fit ​​piece, and the inner wall of the snap-fit ​​piece is provided with anti-slip texture.

[0007] By adopting the above technical solutions, the overall stability of the device is improved, making it less prone to deformation or damage during installation and use. The right-angle structure facilitates close contact with the formwork and reinforcing bars, reducing adjustment work during installation and improving construction efficiency.

[0008] Furthermore, the mounting slot can be mounted with an external template, and the snap-fit ​​tab engages and slides with the external template to improve the stability of the snap-fit ​​tab on the external template.

[0009] By adopting the above technical solutions, the mounting slot can be firmly attached to the external template, ensuring the stability of the device on the template. The snap-fit ​​and sliding design of the snap-fit ​​piece and the template further enhances the stability of the device. The anti-slip texture effectively prevents the device from falling off or loosening during the sliding process, thus improving construction safety.

[0010] Furthermore, the outer surface of the second piece abuts against the outer circumferential reinforcing bar, and the thickness can be limited after the second piece abuts against the outer circumferential reinforcing bar.

[0011] By adopting the above technical solution and through precise dimensional design, the thickness of the steel reinforcement protective layer can be accurately controlled, improving construction accuracy. This design ensures the uniformity and consistency of the steel reinforcement protective layer, thereby extending the service life of the structure and improving its safety.

[0012] Furthermore, a chamfer is provided on the outer side of the junction between the first piece and the second piece.

[0013] By adopting the above technical solution, the chamfer reduces the sharp parts of the device's edges, lowering the risk of damage when it collides with other objects at the construction site. At the same time, the chamfer also makes the device more stable when stacked or stored, reducing damage or deformation caused by edge collisions and improving the device's durability.

[0014] Furthermore, the top of the second piece is provided with an inclined surface.

[0015] By adopting the above technical solutions, the inclined surface design may help reduce resistance during concrete pouring, allowing the concrete to flow more smoothly and fill the gaps between the formwork and the reinforcing bars. In addition, the inclined surface may also play a guiding role in the slipform construction process, helping to keep the device sliding up with the formwork more smoothly.

[0016] Furthermore, the retaining device is made entirely of stainless steel, and multiple sets of the retaining device are provided.

[0017] By adopting the above technical solution, stainless steel material has good corrosion resistance and durability, and is suitable for various complex construction environments and conditions. Multiple sets can be set up to flexibly adjust the number and position of the holding devices as needed to meet the needs of different construction sections.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model, through the design of curved plates, mounting grooves, snap-fit ​​pieces, and anti-slip textures, features an integrated right-angle structure composed of a first and second piece. This not only significantly enhances the stability of the device but also greatly simplifies the installation process. The right-angle structure allows for a tight fit between the template and the reinforcing bars, reducing tedious adjustments during installation. The ingeniously designed curved plate at the top of the first piece allows for a secure mounting groove on the inner side to the external template, while the snap-fit ​​piece at the bottom further enhances the device's stability through its engagement and sliding with the template. The anti-slip texture on the inner wall effectively prevents the device from falling off or loosening during sliding. The second piece, through precise dimensional design, tightly abuts against the external circumferential reinforcing bars, thereby accurately controlling the thickness of the reinforcing bar protective layer. This not only improves construction accuracy but also ensures the uniformity and consistency of the protective layer, providing a strong guarantee for extending the service life of the structure. In summary, this retaining device, with its unique design, stable structure, precise thickness control, and the corrosion resistance and durability of stainless steel, significantly improves construction efficiency and enhances structural safety.

[0020] 2. This utility model incorporates a chamfer, which effectively reduces stress concentration and disperses forces from the formwork, reinforcing bars, and concrete pouring. This reduces the risk of material fatigue or damage due to long-term stress. At the same time, the chamfer improves the compatibility of the device with the construction environment, making the device more responsive to other objects and reducing scratches and jamming. It also enhances the stability of the device when stacked or stored, reducing the possibility of damage or deformation. Attached Figure Description

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1:

[0031] A device for maintaining the thickness of the protective layer for reinforcing bars during slipform construction of a heat-absorbing tower wall, such as... Figures 1-4As shown, the device includes a retaining device 1, which comprises a first piece 101 and a second piece 102. The first piece 101 and the second piece 102 are integrally formed and are arranged at right angles. A curved plate 104 is provided at the top of the first piece 101, and a mounting groove 105 is formed on the inner side of the curved plate 104. A snap-fit ​​piece 106 is provided at the bottom of the curved plate 104, and the inner wall of the snap-fit ​​piece 106 is provided with anti-slip texture 107. Through the integral right-angle structure design of the first piece 101 and the second piece 102, the structural integrity of the device is maintained, and its overall strength and stability are enhanced. This design enables the retaining device 1 to better withstand the various forces from the template, reinforcing bars and concrete pouring during slipform construction, reducing the risk of deformation or damage caused by structural instability.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The mounting slot 105 can be attached to the external template, and the snap-fit ​​piece 106 engages and slides with the external template to improve the stability of the snap-fit ​​piece 106 on the external template. The design of the mounting slot 105 makes it easy for the retaining device 1 to be attached to the external template, simplifying the installation process and improving construction efficiency. At the same time, the snap-fit ​​and sliding design of the snap-fit ​​piece 106 with the external template, together with the use of anti-slip texture 107, significantly enhances the stability of the retaining device 1 on the external template, prevents it from falling off or slipping during construction, and ensures the safety and accuracy of construction.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The outer surface of the second piece 102 abuts against the outer circumferential reinforcing bars, and the thickness can be limited after the second piece 102 abuts against the outer circumferential reinforcing bars. The tight abutment design between the outer surface of the second piece 102 and the outer circumferential reinforcing bars enables precise control of the thickness of the reinforcing bar protective layer. This design not only improves construction accuracy but also ensures the uniformity and consistency of the reinforcing bar protective layer, thereby effectively extending the service life of the heat absorption tower wall and enhancing its structural safety.

[0034] Example 2:

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4A chamfer 108 is provided on the outer side of the joint between the first piece 101 and the second piece 102. The chamfer 108 provided on the outer side of the joint between the first piece 101 and the second piece 102 effectively disperses stress concentration and reduces stress concentration caused by sharp edges. This not only improves the durability of the holding device 1, but also reduces the risk of damage caused by stress concentration. At the same time, it makes the device more stable when stacked or stored, reducing the possibility of collision damage.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the second piece 102 is provided with an inclined surface 103. The inclined surface 103 at the top of the second piece 102 plays a guiding role in the concrete pouring process, so that the concrete can flow more smoothly and fill the gap between the formwork and the reinforcing steel, reducing the resistance during pouring. In addition, the design of the inclined surface 103 also helps to maintain the smooth sliding of the device during slipform construction, improving construction efficiency.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The entire holding device 1 is made of stainless steel. Multiple sets of holding devices 1 are provided. Using stainless steel as the overall material of the holding device 1 not only improves the corrosion resistance and durability of the device, but also makes it suitable for various complex construction environments and conditions. At the same time, the setting of multiple sets of holding devices 1 allows the number and position of the devices to be flexibly adjusted according to actual needs during construction, meeting the needs of different construction sections and improving the flexibility and efficiency of construction. The choice of stainless steel material also facilitates cleaning and maintenance, reducing maintenance costs and management difficulties during long-term use.

[0038] The implementation principle of this utility model is as follows: First, ensure that the entire holding device 1 is intact, the right-angle structure of the first piece 101 and the second piece 102 is stable, and the components such as the curved piece 104, the mounting groove 105, the snap-fit ​​piece 106 and the anti-slip texture 107 are intact. Then, hang the mounting groove 105 on the inner side of the curved piece 104 at the top of the first piece 101 of the holding device with the external template to ensure that the mounting is firm. Use the snap-fit ​​piece 106 to engage and slide with the external template. Improve stability through the anti-slip texture 107 on the inner wall of the snap-fit ​​piece to ensure that the holding device is accurately positioned on the template and is not easy to loosen. Abut the outer surface of the second piece 102 is abutted with the external circumferential steel bar. Through precise size design, the thickness is limited to ensure that the thickness of the steel bar protective layer meets the design requirements.

[0039] After the retaining device is installed in place, concrete is poured. Care should be taken to control the pouring speed and vibration force to avoid impact or displacement of the retaining device and reinforcing steel.

[0040] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
