[0002] Modern buildings often involve large-volume concrete construction, such as bridge approach caps, high-rise building foundations, large equipment foundations, water conservancy dams, etc. Its main feature is its large volume, with the smallest cross-section being 1m in any direction. Its surface coefficient is relatively small, the heat release of cement hydration is relatively concentrated, and the internal temperature rises relatively quickly. When the temperature difference between the inside and outside of concrete is large, temperature cracks will occur in the concrete, affecting the structural safety and normal use.

[0004] Existing cooling water pipes are usually arranged around the outside of concrete casting blocks. When the volume of the concrete casting blocks is large, the cooling water pipes have insufficient cooling capacity to the rising temperature inside the concrete casting blocks, which can easily lead to excessive temperature difference between the inside and outside of the concrete casting blocks, uneven force inside the concrete blocks, and cracks on the concrete surface.

[0028] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0029] See also Figure 1-6 As shown, a temperature control cooling device for pouring a large volume concrete structure is used to cool a concrete structure body 1, comprising:
[0030] A plurality of U-shaped pipe fittings 2, wherein the plurality of pipe fittings 2 are respectively pre-buried vertically in the concrete structure body 1 and evenly arranged along the length direction of the concrete structure body 1, and the opening at the head end and the opening at the tail end of each pipe fitting 2 are used as water holes 2.1, and the two water holes 2.1 leak out to the top of the end surface of the concrete structure body 1;
[0031] A plurality of water channels 3, wherein the water channels 3 are composed of a plate structure surrounding the upper end surface of the concrete structure body 1, and the plurality of water channels 3 are evenly arranged along the length direction of the concrete structure body 1;
[0032] Of the two adjacent pipe fittings 2 , the water hole 2.1 at the tail end of one pipe fitting 2 and the water hole 2.1 at the head end of the other pipe fitting 2 respectively enter the water channel 3 , and the water channel 3 connects the two adjacent pipe fittings 2 .
[0033] After adopting the above structure, the temperature control cooling device for pouring a large-volume concrete structure of the utility model has the following advantages compared with the prior art: if the concrete structure body 1 needs to be cooled, cooling water is introduced into the water hole 2.1 at the head end of the pipe 2 located at the head end of the concrete structure body 1, and the cooling water enters the pipe 2 and enters the water trough 3 through the water hole 2.1 at the tail end of the pipe 2. The water trough 3 is also provided with a water hole 2.1 at the head end of the next pipe 2. The water in the water trough 3 enters the next pipe 2, and passes through a plurality of pipes 2 and the water trough 3 in sequence, and is finally discharged from the tail end of the concrete structure body 1;
[0034] The pipe 2 embedded in the concrete structure body 1 can take away a large amount of accumulated heat inside the concrete structure body 1 when water passes through; the water flowing in the water channel 3 can take away the accumulated heat on the surface of the concrete structure body 1. The combination of the two makes the concrete structure body 1 cool better and avoids cracking.
[0035] As an improvement of the present utility model, the concrete structure body 1 is a long strip structure;
[0036] The center line A of the pipe 2 intersects with the center line B of the concrete structure body 1. The device is more suitable for products such as the long strip structure concrete structure body 1;
[0037] The structural design in which the center line A of the pipe fitting 2 intersects the center line B of the concrete structure body 1 makes the structure of the pipe fitting 2 reasonably arranged and can cool the concrete structure body 1 more evenly.
[0038] As an improvement of the present invention, the pipe 2 is rotated clockwise with the intersection as the rotation axis until the center line A and the center line B of the concrete structure body 1 are obliquely intertwined;
[0039] The angle c between the center line A of the pipe 2 and the center line B of the concrete structure body 1 is 10°-80°. The above improvement sets the pipe 2 as an inclined structural design. Compared with the pipe 2 not set inclined, more cooling areas can be obtained, and fewer pipes 2 can be arranged on the concrete structure body 1, which reduces the cost and has a relatively high structural strength.
[0040] In addition, the area between adjacent pipes 2 is an inclined area, which reduces the heat accumulation effect and is more conducive to cooling the concrete structure body 1.
[0041] As an improvement of the present utility model, the plate structure includes side water retaining plates 4 arranged corresponding to the front and rear sides of the concrete structure body 1, and end water retaining plates 5 arranged corresponding to the front and rear end surfaces of the concrete structure body 1;
[0042] A plurality of partitions 6 connected to the water baffle plate are arranged above the end surface of the concrete structure body 1, and the front and rear ends of the partitions 6 are respectively connected to the side water baffle plates 4 arranged on the front and rear sides of the concrete structure body 1, and the inner sides of the side water baffle plates 4 cooperate with each other to form the water trough 3. The side water baffle plates 4 and the end water baffle plates 5 are detachably connected, and the partitions 6 and the side water baffle plates 4 are detachably connected. Users can connect the partitions 6 at corresponding positions according to the arrangement requirements of the pipe body to form a water trough 3, so that the water hole 2.1 at the tail end of one of the two adjacent pipe fittings 2 and the water hole 2.1 at the head end of the other pipe fitting 2 respectively enter the water trough 3;
[0043] The detachable side water baffles 4, end water baffles 5, and partitions 6 facilitate the disassembly and assembly by the user, and have good combination performance and applicability. When cooling the concrete structure body 1, the operation steps are less complicated.
[0044] As an improvement of the utility model, a water inlet groove 7 is formed between the end surface water retaining plate 5 located at the head end of the concrete structure body 1 and the adjacent partition plate 6, and the water hole 2.1 at the head end of the pipe 2 located at the head end of the concrete structure body 1 is located in the water inlet groove 7;
[0045] A circulating water tank 8 is formed between the end water retaining plate 5 and the adjacent partition plate 6 at the rear end of the concrete structure body 1, and the water hole 2.1 at the rear end of the pipe 2 at the rear end of the concrete structure body 1 is located in the water inlet tank 7. With the above improvement, the user passes water into the water inlet tank 7, and the water can flow to the circulating water tank 8 through the pipe 2 and the water tank 3 in sequence. When the water supply equipment is missing, the above process can enable the device to effectively cool the concrete structure body 1.
[0046] As an improvement of the utility model, the water inlet tank 7 is connected to a water collection tank 7.1 through a pipeline, the water collection tank 7.1 is connected to a sedimentation tank, and the sedimentation tank is connected to the circulating water tank 8 through a pipeline. After the above improvement, the user pumps the water in the water collection tank 7.1 into the water inlet tank 7 through a pump, and the water flowing into the circulating water tank 8 enters the sedimentation tank, and after effective sedimentation in the sedimentation tank, enters the water collection tank 7.1 again for use;
[0047] After the above improvements, a relatively simple water filtering and recycling function is achieved, making the device relatively water-saving and more environmentally friendly.
[0048] As an improvement of the utility model, the water holes 2.1 at the head end and the water holes 2.1 at the tail end of the pipe 2 in the water trough 3 are respectively arranged upward, and the height of the water holes 2.1 at the tail end is higher than the height of the water holes 2.1 at the head end. After the above improvement, after water enters the water trough 3, it can naturally enter the water holes 2.1 at the head end with a lower height, and enter the next pipe 2.
[0049] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
