Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and in particular to a modular large-volume concrete water cooling pipe that also serves as a steel reinforcement support and its installation method. Background Technology

[0002] In the construction of large-volume concrete, temperature cracks are easily caused by the heat of cement hydration. The traditional method involves separate and independent construction of the steel reinforcement support frame and the water cooling pipes. The traditional construction process is as follows: ① Erect the steel reinforcement support frame → ② Tie the main steel reinforcement → ③ Dismantle the steel reinforcement support frame → ④ Erect the water cooling pipe support frame again → ⑤ Lay the water cooling pipes → ⑥ Pour the large-volume concrete.

[0003] Although traditional processes are widely used, they have systemic technical defects, which are analyzed in detail below:

[0004] 1. Fragmented work processes and low construction efficiency. Steel bars and water cooling pipes belong to different construction teams, and cross-operations lead to frequent work stoppages due to material shortages; steel bar support frames and water cooling pipe support frames need to be repeatedly erected and dismantled; management complexity is high.

[0005] 2. Risks of positioning deviation and temperature control failure. Water cooling pipes are fixed to temporary supports by wire binding or welding. Impact from concrete pouring can easily cause them to shift, and vibration of the reinforcing steel frame can lead to excessive vertical elevation deviations of the pipes. Pipe misalignment can create localized cooling blind spots and excessive temperature stress; uncontrolled spacing between the pipes and reinforcing steel may cause stress concentration.

[0006] 3. Material waste and low economic efficiency. The reuse rate of steel reinforcement support frames and water cooling pipe support frames is insufficient, resulting in significant waste, increased labor costs, and extended construction period.

[0007] 4. Insufficient modularity and weak adaptability. The steel reinforcement and water cooling pipe systems are installed and constructed independently, resulting in low coordination, insufficient standardization and modularity, complex construction, and weak adaptability.

[0008] Current construction of large-volume concrete water-cooling pipe systems generally suffers from numerous problems, including fragmented construction processes, loss of precision control, poor economic efficiency, and weak adaptability. The root cause lies in the mechanical stacking and repeated assembly and disassembly of the steel reinforcement support frame and the water-cooling pipe support frame, rather than functional integration and modular structure. Therefore, there is a need to provide a modular large-volume concrete water-cooling pipe that also serves as a steel reinforcement support and its installation method, which can solve the problems of fragmented construction processes, loss of precision control, poor economic efficiency, and weak adaptability in existing technologies. Summary of the Invention

[0009] The purpose of this invention is to provide a modular large-volume concrete water cooling pipe that also serves as a steel reinforcement support and its installation method, which can solve the problems of process fragmentation, loss of precision control, poor economy, and weak adaptability in the prior art.

[0010] To achieve the above objectives, the technical solution of the present invention is as follows:

[0011] A modular large-volume concrete water cooling pipe that also serves as a steel reinforcement support and its installation method include: several water cooling pipe module units, each water cooling pipe module unit including a cooling water cooling pipe, a fixed water cooling pipe, and a vertical support rod, the cooling water cooling pipe, the fixed water cooling pipe, and the vertical support rod being vertically connected in pairs to form a three-dimensional support; during horizontal expansion assembly, the cooling water cooling pipes of two horizontally adjacent water cooling pipe module units are connected to form a tiered water cooling pipe, and the fixed water cooling pipes of two horizontally adjacent water cooling pipe module units are connected to form a tiered horizontal support rod; during vertical expansion assembly, the vertical support rods of two vertically adjacent water cooling pipe module units are coaxially connected, and the several water cooling pipe module units are assembled horizontally and vertically to form a steel reinforcement support structure.

[0012] Each of the aforementioned water cooling pipe module units includes two cooling water cooling pipes, two fixed water cooling pipes, and four vertical support rods. The two cooling water cooling pipes are arranged symmetrically along the transverse direction of the water cooling pipe module unit, and the two fixed water cooling pipes are arranged symmetrically along the longitudinal direction of the water cooling pipe module unit, so that the two cooling water cooling pipes and the two fixed water cooling pipes are connected in a grid-like structure. The four vertical support rods are vertically connected to the four connection nodes of the two cooling water cooling pipes and the two fixed water cooling pipes.

[0013] At the edge of the steel reinforcement support structure, two cooling water pipes located within the same water cooling pipe module unit are connected to the outside of the water cooling pipe module unit through a first U-shaped joint. Two adjacent cooling water pipes within two horizontally adjacent water cooling pipe module units are connected to the outside of the water cooling pipe module unit through a second U-shaped joint. Inside the steel reinforcement support structure, two adjacent cooling water pipes within the same layer are connected through a straight threaded joint, so that the layered water cooling pipes are arranged in a serpentine manner.

[0014] The fixed water cooling pipes in two adjacent water cooling pipe module units located on the same layer are connected by straight threaded joints to form multiple parallel and spaced tiered transverse support rods.

[0015] The cooling water pipes of the tiered water cooling pipes in adjacent layers are arranged perpendicularly to each other, and the fixing water cooling pipes of the tiered transverse support rods in adjacent layers are arranged perpendicularly to each other.

[0016] Both the cooling water pipe and the fixed cooling water pipe are fixed to the vertical support rod by U-shaped grooves and hexagonal bolts.

[0017] The cooling water pipe, the fixed cooling water pipe, and the vertical support rod can all serve as fixed supports for the pre-embedded sensor.

[0018] The vertical support rod is an equal-limb angle steel. Each limb of the equal-limb angle steel has several connecting holes spaced apart along its entire vertical length, so that two vertically adjacent vertical support rods are connected through one of the connecting holes by a connector. The vertical connection node of the two vertical support rods is located between the tiered water cooling pipe and the tiered transverse support rod of the two adjacent layers.

[0019] A detachable grid is laid on the horizontal support rods at the top layer of the steel reinforcement support structure to form a top layer steel reinforcement binding platform.

[0020] A pad is provided at the lower end of the vertical support rod located at the bottom of the steel reinforcement support structure.

[0021] An installation method for a modular, large-volume concrete water cooling pipe that also serves as a steel reinforcement support includes the following steps:

[0022] Step 1: Standardized processing of cooling water pipes, fixed cooling water pipes, and vertical support rods is completed in the factory;

[0023] Step 2: On-site measurement and layout positioning;

[0024] Step 3: Binding the bottom reinforcement of large-volume concrete;

[0025] Step 4: At the construction site, water cooling pipe module units are assembled using cooling water pipes, fixed water cooling pipes, and vertical support rods;

[0026] Step 5: The water cooling pipe module unit is hoisted into place and connected longitudinally and laterally to form the first layer of water cooling pipes and lateral support rods;

[0027] Step 6: The water cooling pipe module units are vertically extended and connected to form a three-dimensional support;

[0028] Repeat steps 5 and 6 to complete the m-th layer of the three-dimensional support structure, forming a steel support structure.

[0029] Step 7: For the tiered water cooling pipes within the same layer, two cooling water cooling pipes located within the same water cooling pipe module unit are connected to the outside of the water cooling pipe module unit through a first U-shaped connector; two adjacent cooling water cooling pipes located within adjacent water cooling pipe module units are connected to the outside of the water cooling pipe module unit through a second U-shaped connector; cooling water cooling pipes located within adjacent water cooling pipe module units are connected to the inside of the steel reinforcement support structure through a straight threaded connector, forming a tiered water cooling pipe; fixed water cooling pipes located within adjacent water cooling pipe module units are connected to the inside of the steel reinforcement support structure through a straight threaded connector, forming a tiered transverse support rod; perform a water flow test on the tiered water cooling pipes;

[0030] Step 8: Lay a grid on the horizontal support rods of the top layer of the steel reinforcement support structure to form a top layer steel reinforcement binding platform, and bind the top layer steel reinforcement of the large volume concrete on the top layer steel reinforcement binding platform.

[0031] Step 9: Install temperature measuring points in the middle of the tiered water cooling pipes and / or tiered horizontal support rods;

[0032] Step 10: Pour large volume concrete;

[0033] Step 11: Water is circulated through the water cooling pipes of each layer to cool the interior of the large-volume concrete.

[0034] Step 12: Grout and seal the water cooling pipes and horizontal support rods of each level.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. This invention integrates the steel reinforcement and water cooling pipe processes, reducing overlapping operations, avoiding downtime due to material shortages, reducing management complexity, and improving construction efficiency. At the same time, the cooling water pipes and fixed water cooling pipes are made of steel pipes, which can serve as both water cooling pipes and steel reinforcement supports, reducing the amount of temporary support steel used, reducing labor costs, shortening the construction period, and saving costs.

[0037] 2. The water cooling pipe module unit of the present invention is manufactured in a standardized manner in the factory. It can be assembled and expanded arbitrarily in the horizontal, vertical and horizontal directions on the construction site. The assembly is simple and convenient, the connection is reliable, and it has strong adaptability to the requirements of large-volume concrete of different sizes (length, width and height) and the internal water cooling pipe layout. It is convenient for iterative upgrades. At the same time, it can accurately position the water cooling pipe, ensure the temperature control accuracy inside the large-volume concrete, control construction errors, and avoid local cooling blind spots that cause temperature difference cracking.

Detailed Implementation

[0043] The modular large-volume concrete water cooling pipe that also serves as a steel reinforcement support and its installation method, proposed in this invention, will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0044] Please see the appendix Figure 1 To be continued Figure 3 A modular, large-volume concrete water cooling pipe that also serves as a steel reinforcement support includes several water cooling pipe module units. Each water cooling pipe module unit includes a cooling water cooling pipe 1, a fixed water cooling pipe 2, and a vertical support rod 3. The cooling water cooling pipe 1, the fixed water cooling pipe 2, and the vertical support rod 3 are vertically connected in pairs to form a three-dimensional support. When assembling horizontally (including laterally and longitudinally), the cooling water cooling pipes 1 of two horizontally adjacent water cooling pipe module units are connected to form a hierarchical water cooling pipe. The fixed water cooling pipes 2 of two horizontally adjacent water cooling pipe module units are connected to form a hierarchical lateral support rod. When assembling vertically, the vertical support rods 3 of two vertically adjacent water cooling pipe module units are coaxially connected. Several water cooling pipe module units are assembled horizontally and vertically to form a steel reinforcement support structure.

[0045] The water cooling pipe module is treated as a modular unit. Multiple water cooling pipe modules are spliced ​​together horizontally, vertically, and vertically to form a three-dimensional regular grid-like steel support structure of different sizes. This structure can adapt to large-volume concrete structures of different sizes. It has a high degree of standardization, and the independent modules are clear and concise, which facilitates the precise positioning of water cooling pipes, ensures temperature control accuracy, and ensures reliable structural connections.

[0046] The cooling water pipe 1 and the fixed cooling water pipe 2 serve not only as cooling water pipes in the water cooling pipe module unit but also as supporting components of the steel reinforcement support structure. By combining the steel reinforcement process with the water cooling pipe process, construction efficiency can be improved, material consumption can be reduced, and economic benefits can be increased. This invention can solve the problems of process fragmentation, loss of precision control, poor economy, and weak adaptability caused by the separate and independent construction of the steel reinforcement support frame and the water cooling pipe support frame in existing construction technologies.

[0047] Please see the appendix Figure 2 Each of the aforementioned water cooling pipe module units includes two cooling water cooling pipes 1, two fixed water cooling pipes 2, and four vertical support rods 3. The two cooling water cooling pipes 1 are arranged symmetrically along the transverse direction of the water cooling pipe module unit, and the two fixed water cooling pipes 2 are arranged symmetrically along the longitudinal direction of the water cooling pipe module unit, so that the two cooling water cooling pipes 1 and the two fixed water cooling pipes 2 are connected in a grid-like structure. The four vertical support rods 3 are vertically connected to the four connection nodes of the two cooling water cooling pipes 1 and the two fixed water cooling pipes 2, respectively.

[0048] Preferably, the plane where the water cooling pipe module unit is located has a square structure, which has a high degree of standardization and is easy to process and manufacture. The overall structure adopts a symmetrical structure, which is convenient and simple to assemble. It can be expanded and assembled into steel support structures of different sizes according to actual use needs.

[0049] Please see the appendix Figure 2 At the edge of the steel reinforcement support structure, two cooling water pipes 1 located in the same water cooling pipe module unit are connected to the outside of the water cooling pipe module unit through a first U-shaped connector 4. Two adjacent cooling water pipes 1 in two horizontally adjacent water cooling pipe module units are connected to the outside of the water cooling pipe module unit through a second U-shaped connector 5. Inside the steel reinforcement support structure, two adjacent cooling water pipes 1 in the same layer are connected through a straight threaded connector 6, so that the layered water cooling pipes are arranged in a serpentine manner.

[0050] The first U-shaped connector 4 is used to connect two parallel cooling water pipes 1 within the same water cooling pipe module unit. The second U-shaped connector 5 is used to connect two adjacent parallel cooling water pipes 1 within adjacent water cooling pipe module units. The straight thread connector 6 is used to connect two coaxially aligned cooling water pipes 1 within adjacent water cooling pipe module units, thereby ensuring that all cooling water pipes 1 within the same layer can be connected to form a serpentine arrangement of hierarchical water cooling pipes.

[0051] Please see the appendix Figure 2 The fixed water cooling pipes 2 in two adjacent water cooling pipe module units located on the same layer are connected by a straight threaded joint 6 to form multiple parallel and spaced tiered transverse support rods.

[0052] Two coaxially aligned fixed water cooling pipes 2 in adjacent water cooling pipe module units within the same layer are connected by a straight threaded connector 6, forming a single, integrated tiered horizontal support rod that serves as a bracket for rebar tying. Simultaneously, when needed, the fixed water cooling pipes 2 can be connected and circulated with water for internal concrete temperature control. The connection method is the same as that used for connecting cooling water cooling pipes 1 to form a tiered water cooling pipe system, and will not be elaborated further here.

[0053] Please see the appendix Figure 3 The cooling water pipes 1 of the tiered water cooling pipes in two adjacent layers are arranged perpendicularly to each other, and the fixing water cooling pipes 2 of the tiered transverse support rods in two adjacent layers are arranged perpendicularly to each other.

[0054] One end of the tiered water cooling pipe serves as the water inlet (connected to the water inlet pipe via a straight threaded connector 6), and the other end serves as the water outlet (connected to the water outlet pipe via a straight threaded connector 6). The water inlet and outlet directions of the tiered water cooling pipes in adjacent layers are arranged perpendicularly. For example, the water inlet and outlet directions of the first layer of tiered water cooling pipes are transverse along the steel reinforcement support structure, and the water inlet and outlet directions of the second layer of tiered water cooling pipes are longitudinal along the steel reinforcement support structure.

[0055] Please see the appendix Figure 1 The cooling water pipe 1 and the fixed cooling water pipe 2 are both fixed to the vertical support rod 3 by means of U-shaped groove 7 and hexagonal bolts.

[0056] The size of the U-shaped slot 7 can be adapted to the size of the cooling water pipe 1 and the fixed cooling water pipe 2, with a total of 8 U-shaped slots 7 and 16 hexagonal bolts.

[0057] Please see the appendix Figure 3 A detachable grid is laid on the horizontal support rod at the top layer of the steel reinforcement support structure to form a top layer steel reinforcement binding platform 8, which is used to bind the top layer steel reinforcement of large volume concrete.

[0058] The cooling water pipe 1, the fixed cooling water pipe 2, and the vertical support rod 3 can all serve as fixed supports for the pre-embedded sensors, supporting the direct burial of existing fiber optic temperature measurement systems and facilitating the monitoring of the internal temperature of large-volume concrete.

[0059] The steel pipe has high structural strength and strong load-bearing capacity. It can be used as a water cooling pipe 1 and a fixed water cooling pipe 2, and can also be used as a steel reinforcement support frame and a support frame. At the same time, it provides convenient fixed support for embedded sensors, so as to detect the temperature of various measuring points inside large-volume concrete through the existing fiber optic temperature measurement system.

[0060] The vertical support rod 3 is an equal-limb angle steel. Each limb of the equal-limb angle steel is provided with a number of connection holes (not shown in the figure) at intervals along the entire vertical length. Two vertically adjacent vertical support rods 3 are connected through one of the connection holes by a connector (such as a hexagonal bolt and nut assembly). The vertical connection node of the two vertical support rods 3 is located between the layer water cooling pipe and the layer transverse support rod of the two adjacent layers.

[0061] Equal-limb angle steel is used as the vertical support rod 3, which is easy to assemble and disassemble, has a simple structure, and is reliable in connection.

[0062] A pad 9 is provided at the lower end of the vertical support rod 3 located at the bottom of the steel reinforcement support structure. The pad 9 can increase the contact area between the vertical support rod 3 and the ground or other working surfaces, thereby improving the stability of the entire steel reinforcement support structure.

[0063] Preferably, in order to minimize the number of water cooling pipe supports and increase the support span, the steel pipes for cooling water cooling pipe 1 and fixed water cooling pipe 2 are selected from the D50 type with the maximum specified diameter as specified in the "Technical Specification for Temperature Measurement and Control of Mass Concrete" (GB / T51028-2015).

[0064] According to Clause C.0.1 of the "Technical Specification for Temperature Measurement and Control of Mass Concrete" (GB / T 51028-2015), "When water cooling pipes are arranged horizontally, the distance between the water pipes and the edge of the concrete should be 1500mm to 2000mm." Therefore, the sum of the distances between the two opposite water cooling pipes and the edge of the concrete should be 3000mm to 4000mm. Considering that the water pipe arrangement must meet the concrete protective layer thickness requirements in extreme cases, and that the distance between the water pipes and the edge of the concrete should not be too large to affect the cooling effect, the maximum length of the cooling water cooling pipe 1 and the fixing water cooling pipe 2 in each water cooling pipe module unit can be 3000mm. This not only adapts to the planar installation of water cooling pipes in various long and wide large-volume concrete structures, but also reduces the number of water cooling pipe joints, facilitating rapid installation. Correspondingly, the planar dimensions of each water cooling pipe module unit are 3000mm × 3000mm.

[0065] According to Article 6.3.2 of the "Technical Specification for Temperature Measurement and Control of Mass Concrete" (GB / T 51028-2015), the spacing between steel pipes can be 1000-2000mm. Considering that the length of cooling water pipe 1 and fixed water cooling pipe 2 is 3000mm, and both ends are equipped with direct heads for connection with straight threaded connectors 6, to avoid conflict between the direct heads and the vertical support rods 3, and considering that the vertical support rods 3 are symmetrically arranged along the length of cooling water pipe 1 and fixed water cooling pipe 2 for convenient and rapid positioning and installation, the vertical support rods 3 can be set at one-quarter of the length of cooling water pipe 1 and fixed water cooling pipe 2. That is, the spacing of cooling water pipe 1, the spacing of fixed water cooling pipe 2, and the horizontal spacing of vertical support rods 3 are set to 1500mm (≥1000mm and ≤2000mm).

[0066] Since the cooling water pipes 1 and fixed water pipes 2 are arranged horizontally in each layer, and the cooling water pipes 1 and fixed water pipes 2 in the upper and lower layers are usually arranged vertically, in order to facilitate the precise fitting and fixing of the cooling water pipes 1 and fixed water pipes 2, the vertical support rod 3 can be made of equal-limb angle steel L100.

[0067] According to Article 6.3.3-2 of the "Technical Specification for Temperature Measurement and Control of Mass Concrete" (GB / T 51028-2015), "The spacing between cooling water circuits in each layer should be 1.5m." To minimize the number of vertical joints and facilitate rapid installation, the first vertical connection node of the vertical support rod 3 is located in the middle between the tiered cooling water pipes of the first and second layers (avoiding the tiered cooling water pipes as much as possible). The length of the vertical support rod 3 can be either 2500mm (1500mm + 0.5 × 1500mm = 2250mm, rounded to 2500mm) or 1000mm (to accommodate the height of various mass concrete structures while avoiding excessively long joints at vertical connection nodes). Simultaneously, to accommodate the height requirements of various cooling water pipe arrangements, the spacing between the openings of the connection holes (bolt holes) along the entire vertical length of each leg of the equal-leg angle steel of the vertical support rod 3 is set to 100mm.

[0068] Both the cooling water pipe 1 and the fixed water cooling pipe 2 are fixed to the vertical support rod 3 by U-shaped slots and hexagonal bolts and nuts, forming a water cooling pipe module unit.

[0069] The water cooling pipe module unit can be freely spliced ​​and expanded horizontally, vertically, and horizontally to form a large-volume concrete structure that can adapt to various sizes (length, width, height) and meet the functional requirements of the steel reinforcement support frame and the water cooling pipe support frame.

[0070] Please see the appendix Figure 1 To be continued Figure 3 A modular, large-volume concrete water cooling pipe that also serves as a steel reinforcement support includes the following steps:

[0071] Step 1: Based on the construction requirements of large-volume concrete, complete the standardized and precise processing of cooling water pipe 1, fixed cooling water pipe 2 and vertical support rod 3 in the factory.

[0072] Step 2: On-site measurement and layout positioning.

[0073] Step 3: Binding the bottom reinforcement of the large-volume concrete.

[0074] Step 4: At the construction site, the water cooling pipe module unit is assembled by using cooling water pipe 1, fixed water cooling pipe 2, and vertical support rod 3.

[0075] Step 5: The water cooling pipe module unit is hoisted into place and connected longitudinally and laterally to form the first layer of water cooling pipes and lateral support rods.

[0076] Step 6: Based on the dimensions (length, width, and height) of the large-volume concrete, the water cooling pipe module units are vertically extended and connected to form a three-dimensional support.

[0077] Repeat steps 5 and 6 to complete the m-th layer of the three-dimensional support structure, forming a steel reinforcement support structure.

[0078] Step 7: For the tiered water cooling pipes within the same layer, two cooling water cooling pipes 1 located within the same water cooling pipe module unit are connected to the outside of the water cooling pipe module unit through the first U-shaped connector 4. Two adjacent cooling water cooling pipes 1 located within adjacent water cooling pipe module units are connected to the outside of the water cooling pipe module unit through the second U-shaped connector 5. The cooling water cooling pipes 1 located within adjacent water cooling pipe module units are connected to the inside of the steel reinforcement support structure through the straight thread connector 6, forming a tiered water cooling pipe. The fixed water cooling pipes 2 located within adjacent water cooling pipe module units are connected to the inside of the steel reinforcement support structure through the straight thread connector 6, forming a tiered transverse support rod. A water flow test is performed on the tiered water cooling pipes.

[0079] Step 8: Lay a grid on the horizontal support rods of the top layer of the steel reinforcement support structure to form the top layer steel reinforcement binding platform 8, and bind the top layer steel reinforcement of the large volume concrete on the top layer steel reinforcement binding platform 8.

[0080] Step 9: Based on the internal temperature monitoring requirements of large-volume concrete, set up temperature measurement points in the middle of the tiered water cooling pipes and / or tiered transverse support rods.

[0081] Step 10: Pour large volume concrete.

[0082] Step 11: Water is circulated through the water cooling pipes of each layer to cool the interior of the large-volume concrete.

[0083] Step 12: Grout and seal the water cooling pipes and horizontal support rods of each level.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
