Description

Technical Field

[0001] This utility model relates to a structure combining a large-volume concrete cooling pipe with a steel reinforcement support. Background Technology

[0002] During the pouring of large-volume concrete structures, the cement hydration reaction releases a large amount of heat, causing a rapid rise in the internal temperature of the structure. Due to the poor thermal conductivity of concrete, the internal heat accumulates and is difficult to dissipate, resulting in a significant temperature difference between the interior and surface of the structure, generating enormous thermal stress. When this stress exceeds the early tensile strength of the concrete, it can easily trigger harmful temperature cracks, seriously affecting the integrity, durability, and safety of the structure.

[0003] To control temperature cracks, pre-embedded cooling pipes are commonly used in engineering projects to directly remove heat from the concrete by circulating cooling water within the pipes. However, in traditional construction methods, cooling pipes are usually directly tied to supporting steel bars, which has significant drawbacks: First, under the impact of concrete pouring and vibration, the pipes are prone to displacement, deformation, or even detachment, causing the pre-set cooling circuit to fail; second, pipe joints are prone to forming sharp bends or dead ends due to excessive bending, increasing water flow resistance, affecting cooling efficiency, and even causing blockages; third, temperature probes are usually buried independently, their positions are difficult to fix precisely, they are easily damaged, and they cannot form an effective linkage with the cooling system, resulting in poor data reliability. Therefore, providing an integrated device that can firmly fix cooling pipes, optimize pipeline routing, and integrate temperature measurement functions is crucial for ensuring the construction quality of large-volume concrete. Utility Model Content

[0004] This invention provides a structure combining a large-volume concrete cooling pipe with a steel reinforcement support, which can effectively solve the above-mentioned problems.

[0005] This utility model is implemented as follows: A structure combining a large-volume concrete cooling pipe and a steel reinforcement support includes a support structure for supporting the surface steel reinforcement of the large-volume concrete structure, and a bent guide rod fixedly installed on the support structure. The bent guide rod includes at least a pair of oppositely arranged arc-shaped clamping rods, and an arc-shaped space for clamping and fixing the pipe body is formed between the pair of arc-shaped clamping rods.

[0006] The beneficial effects of this utility model are: (1) In Example 1, the rigid foot support structure assembled from rods and the bent guide rod with arc clamping rod provide an extremely strong welded fixation for the cooling pipe, which can effectively resist the impact of concrete pouring and solve the problem of pipe displacement and damage. At the same time, its arc design can standardize the pipe bending radius and avoid reducing water flow resistance and blockage risk. The integrated auxiliary component has the temperature probe built in and directly contacts the cooling water, realizing accurate and reliable monitoring of cooling efficiency.

[0007] (2) In Example 2, a modular guide positioning plate was added. This component achieves rapid and accurate positioning and installation through the precise cooperation of the pin and the pin hole. The large and small channels on it fix the cooling tube and the temperature measuring element separately, realizing multi-functional integrated management and ensuring the high consistency of the spatial position of all measuring points. This design greatly improves the standardization of construction and positioning accuracy, and lays a solid hardware foundation for intelligent temperature control based on accurate temperature data. It is a key upgrade to realize intelligent construction. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0015] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0016] Example 1 Reference Figure 1-2 As shown, a structure combining a large-volume concrete cooling pipe and a steel reinforcement support includes a support structure 10 for supporting the surface steel reinforcement of the large-volume concrete structure, and a bent guide rod 20 fixedly installed on the support structure 10. The bent guide rod 20 includes at least a pair of oppositely arranged arc-shaped clamping rods 200, forming an arc-shaped space between the pair of arc-shaped clamping rods 200 for clamping and fixing the pipe body 30. The bent guide rod 20 also includes a bent rod 202 connected to the support structure 10 and a limiting bent rod 204 connected to the bent rod 202.

[0017] Specifically, traditional wire binding is a flexible fixation that is prone to loosening. In this embodiment, the arc-shaped clamping rod 200 forms a rigid arc-shaped space that matches the shape of the pipe. After being fixed to the foot support structure 10 by welding or other methods, it can firmly "hold" the pipe 30, effectively resisting the impact of concrete pouring and vibration, and preventing pipe displacement and damage. The "arc" design is key. It acts as a bending guide, guiding the cooling pipe to form a smooth, large-radius bend at this point, avoiding "dead bends" or "sharp bends" caused by construction workers bending arbitrarily. This significantly reduces water flow resistance, lowers pump energy consumption, and fundamentally prevents the risk of blockage caused by excessive bending. Furthermore, the bending rod 202 and the limiting bending rod 204 play a connecting and reinforcing role, forming an integral whole with the arc-shaped clamping rod 200 set on the bending guide rod 20, enhancing the rigidity and stability of the entire fixing device.

[0018] Furthermore, the outer wall of the arc-shaped clamping rod 200 may be designed with anti-slip textures or protrusions to increase the friction with the surface of the tube 30, prevent the tube 30 from rotating or sliding inside, and ensure a more secure fixation.

[0019] It should be noted that the opening spacing of the arc-shaped clamping rod 200 is slightly smaller than the diameter of the tube body 30, giving it a certain elastic clamping force. During installation, a little force is needed to "clamp" the tube body into the arc-shaped space. A "click" sound indicates that the installation is in place. This design provides intuitive installation feedback.

[0020] Furthermore, the limiting bending rod 204 is not only used for connection, but its bending angle and length are specially designed to hook or abut against specific rods of the foot support structure 10 (such as the first rod 100 or the second rod 102). This plays a dual role in positioning and anti-torsion, preventing the bent guide rod 20 from rotating when subjected to external force.

[0021] It also includes an auxiliary component 40, which is detachably installed on the outer wall of the tube body 30 and communicates with the tube body 30. A temperature probe is installed inside the auxiliary component 40.

[0022] Furthermore, the auxiliary component 40 is a detachable pipe fitting (such as a tee or connector) installed on the outer wall of the pipe body 30 and communicating with the inner cavity. A temperature probe is installed inside it. Compared with the traditional method of directly burying the temperature probe in the concrete, which is inaccurate in position and easily damaged, this embodiment places the probe inside the auxiliary component 40 to directly measure the temperature of the cooling water flowing through the cooling pipe. This can most accurately reflect the heat exchange efficiency and provide a highly reliable data source for evaluating the cooling effect and dynamically controlling the water temperature / flow rate. Moreover, the probe is installed through the detachable auxiliary component 40. In case of damage, it can be repaired or replaced without water flow, without damaging the concrete structure.

[0023] In this embodiment, one end of the tee pipe connector is connected to the main pipe 30, the other end is used to extend a branch pipe to accommodate the temperature probe, and the third end can be sealed with a sealing nut to facilitate future maintenance and replacement of the probe (not shown in this case). At the same time, the connection between the auxiliary component 40 and the pipe body 30, as well as the sealing nut, are provided with "O-rings" or coated with waterproof sealant to ensure the airtightness of the entire cooling pipeline and prevent cooling water leakage.

[0024] The foot support structure 10 includes a three-dimensional frame composed of multiple interconnected rods. The three-dimensional frame includes a first rod 100, a second rod 102, a third rod 104, and a fourth rod 106. The first rod 100 has a first slot 1000 for engaging with the second rod 102, the third rod 104 has a second slot 1040, and the fourth rod 106 has a third slot 1060. The three-dimensional frame also includes a first connecting rod 1002 connecting the first rod 100 and the third rod 104, and a second connecting rod 1022 connecting the second rod 102 and the fourth rod 106.

[0025] Specifically, the foot support structure 10 provides extremely high stability, sufficient to support the upper steel mesh and construction loads. Through the design of the first slot 1000, the members can be quickly and accurately positioned and assembled, like "building blocks", ensuring the consistency and high efficiency of construction quality. This avoids the dimensional errors and inconsistent quality caused by temporary cutting and welding of steel bars on site.

[0026] Example 2 Reference Figure 3-4 The difference from Embodiment 1 is that it also includes a guide positioning plate 50, which is detachably mounted on the foot support structure 10 via a pin 504; the guide positioning plate 50 is provided with a retaining plate 506, which has a large channel 508 and a small channel 510, the large channel 508 is used for the pipe body 30 to pass through and be fixed, and the small channel 510 is used to fix the auxiliary component 40; the guide positioning plate 50 also includes a connecting plate 502 connected to the pin 504; the foot support structure 10 is provided with a pin hole 60 adapted to the pin 504.

[0027] Specifically, unlike Embodiment 1, in this embodiment, the guide positioning plate 50 is detachably mounted on the foot support structure 10 through the cooperation of the pin 504 and the pin hole 60. It has a large channel 508 and a small channel 510. The large channel 508 is used to pass through and position the cooling pipe (pipe body 30), and the small channel 510 is specifically used to independently fix the auxiliary component 40 (containing a temperature measuring probe). This design realizes the zoned management and synchronous precise positioning of the cooling pipe and the temperature measuring system. At the same time, through the precise cooperation of the pin 504 and the pin hole 60, it can be ensured that the position of each guide positioning plate 50 is precisely consistent, thereby ensuring that the spatial coordinates of all cooling pipes and temperature measuring points inside the concrete are completely in line with the design expectations. This is a prerequisite for achieving precise temperature control. Furthermore, the guide positioning plate 50 is an independent module that can be selectively installed on specific foot support structures 10 according to engineering design needs (for example, one every few support legs), providing additional reinforcement and precise positioning for key points, combining economy and functionality.

[0028] In this embodiment, the guide positioning plate 50 is preferably integrally molded from non-metallic materials such as nylon and ABS engineering plastics through injection molding. This avoids the "thermal bridge" effect formed by metallic materials and prevents heat from being dissipated too quickly through this component, thus affecting the authenticity of the internal temperature field. At the same time, non-metallic materials are less likely to scratch the tube body 30.

[0029] It should be noted that the retaining plate 506 itself has a certain degree of elasticity. The diameter of the large channel 508 is slightly smaller than the diameter of the tube body 30. During installation, the slight deformation of the retaining plate 506 is used to "hold" the tube body tightly, achieving elastic self-locking and further preventing the pipe from moving. The inner wall of the small channel 510 can be designed with threads for direct screwing into the auxiliary part 40 with external threads or the temperature probe housing, realizing the rapid, firm and sealed installation of the temperature measuring element without the need for additional binding.

[0030] Furthermore, in this embodiment, the words "positioning" or "temperature measurement" can be engraved on the foot support structure 10 next to the pin hole 60, and directional arrows can be engraved on the connecting plate 502 of the guide positioning plate 50. According to the markings, the construction personnel can quickly and accurately install the positioning plate in the correct position and direction, which greatly reduces the probability of errors and ensures the consistency of the position of all temperature measurement points.

[0031] This embodiment is the same as the foot support structure 10 in Embodiment 1, so it will not be described in detail here.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
