Technical Field

[0001] The utility model relates to the technical field of mass concrete construction, in particular to a temperature and humidity control device for mass concrete. Background Art

[0002] Concrete temperature measurement is an indispensable process in civil construction and industrial concrete structure engineering. Concrete construction will cause great changes in temperature caused by the hydration heat of cement due to the increase in design strength grade, the increase in the fineness of cementitious materials in concrete, the addition of various admixtures, and the gradual reduction in water consumption. This will cause plastic shrinkage of concrete in the early stage of pouring and lead to the formation of harmful cracks.

[0003] Patent publication number CN212714491U discloses a temperature and humidity control device for large-volume concrete, comprising a first bracket, a second bracket, two third brackets, a resting tank, and a cold water tank. The first bracket, second bracket, and two third brackets are vertically positioned at the four corners of the large-volume concrete. The first bracket and second bracket are positioned at two diagonally opposite corners, and the two third brackets are positioned at the other two diagonally opposite corners. The first bracket and second bracket are each connected to the two third brackets via three horizontally positioned crossbars. The four crossbars, located on the same horizontal plane, form a rectangular frame. Twelve crossbars collectively form three parallel rectangular frames of varying heights. Large-volume concrete is positioned within the rectangular frames. Several scattering nozzles are evenly positioned on the crossbars, spraying water into the rectangular frames through the scattering nozzles.

[0004] However, the device needs to be customized according to the size of the concrete to be cured. After disassembly, it is difficult to use in concrete curing operations of other sizes. The device has high investment cost and poor applicability. Utility Model Content

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The present application discloses a temperature and humidity control device for large volume concrete, referring to Figure 1 and Figure 2 , including a connecting section 1, a connecting pipe 2 and an adjusting pipe 3. The connecting section 1 is located outside each angle of the concrete member. At least one connecting pipe 2 is connected between the connecting sections 1. The connecting pipe 2 is connected to the connecting section 1 through the adjusting pipe 3. The length of the adjusting pipe 3 is adjustable. Through multiple connecting sections 1, connecting pipes 2 and adjusting pipes 3, a frame that can accommodate concrete members can be formed. The connecting pipes 2 and the connecting pipes 2 and the adjusting pipes 3 are all detachably connected.

[0025] By adjusting the length of the regulating tube 3 and changing the number of connecting tubes 2 between the connecting sections 1, the size of the frame can be flexibly changed, making it suitable for concrete pieces of different sizes. A plurality of spray heads 6 are spaced along one side of the connecting tube 2 along its length. Flow channels are provided within the connecting tube 2, regulating tube 3, and connecting section 1, ensuring that the flow channels within the frame are uniformly connected. A water tank 61 and a water pump 62 are also provided on the outside of the frame. The water tank 61 contains cooling water. The inlet end of the water pump 62 is connected to the water tank 61. The outlet end of the water pump 62 is connected to at least one connecting section 1 via a pipe and can fill the flow channels within the frame with water. This causes the cooling water to be sprayed out from the spray heads 6 as a mist, cooling the concrete pieces placed within the frame.

[0026] In the embodiment of the present application, a plurality of connection seats 22 are provided at intervals on the connection pipe 2, and the sprinkler head 6 is threadedly connected to the connection seat 22. The operator can remove the sprinkler head 6 as needed, replace it with other pipes on the connection seat 22, extend it into the concrete part, and cool the concrete part.

[0027] Reference Figure 3 and Figure 4 Specifically, the connecting section 1 is in the shape of a cube, with connection holes formed on all six sides of the connecting section 1. The six connection holes on the connecting section 1 are interconnected. The connection holes are first threaded holes 11. One end of the regulating tube 3 is provided with a first threaded sleeve 31 that fits into the first threaded hole 11. The first threaded sleeve 31 is threadedly connected to the first threaded hole 11 to connect the regulating tube 3 to the connecting section 1. A first blocking member, specifically a blocking cap 5, is installed in the connection hole on the connecting section 1 that is not connected to the regulating tube 3 or the external water pump 62. The blocking cap 5 is threadedly connected to the first threaded hole 11, thereby sealing the unused connection hole on the connecting section 1.

[0028] Adjacent connecting pipes 2 and the connecting pipes 2 at the end of the adjusting pipe 3 away from the connecting section 1 are connected by a connector. Specifically, a circle of outwardly protruding connecting steps 21 is coaxially provided at the end of the adjusting pipe 3 away from the first threaded sleeve 31. Connecting steps 21 of the same size as those on the adjusting pipe 3 are provided at both ends of the connecting pipe 2. The connector includes two hinged movable flaps 4. The movable ends of the two movable flaps 4 are fixed by bolts. Connecting grooves 41 that adapt to the connecting steps 21 are provided on the inner walls of the two movable flaps 4. A sealing layer is provided in the connecting groove 41, which can be a rubber lining. When the ends of the adjusting pipe 3 and the connecting pipe 2 are aligned, or after the ends of the two connecting pipes 2 are aligned, the connector is used to hold them together in the docking position. When the two movable flaps 4 are tightly held, the sealing layer can effectively seal and waterproof.

[0029] In the embodiment of the present application, the regulating tube 3 includes an inner tube 32, an outer tube 33, and a fastening bolt 34. One end of the inner tube 32 is coaxially inserted into the outer tube 33. The fastening bolt 34 is threadedly connected to the outer tube 33 along the radial direction of the outer tube 33. After passing through the outer tube 33, the fastening bolt 34 abuts against the outer wall of the inner tube 32, thereby limiting relative slippage between the inner tube 32 and the outer tube 33. To ensure a seal between the inner tube 32 and the outer tube 33, a second sealing member is provided on the end of the outer tube 33 from which the inner tube 32 extends. The second sealing member includes a sealing sleeve 71 and a sealing rubber sleeve 72. The sealing sleeve 71 is coaxially sleeved on the outside of the inner tube 32 and can be threadedly connected to the outer tube 33. The sealing rubber sleeve 72 is coaxially sleeved on the outside of the inner tube 32 and is located between the sealing sleeve 71 and the outer tube 33.

[0030] Furthermore, the sealing sleeve 72 has an L-shaped cross-section, with a first guiding bevel provided at the included angle of the sealing sleeve 72. A second guiding bevel is provided on the edge of the inner ring of the sealing sleeve 71 near the outer sleeve 33, and a Teflon layer 73 is provided on the second guiding bevel. When the sealing sleeve 71 is threadedly tightened onto the outer sleeve 33, the second guiding bevel contacts the first guiding bevel, and the Teflon layer 73 reduces the friction between the two. The sealing sleeve 71 pushes the sealing sleeve 72 into close contact with the outer wall of the inner tube 32, and at the same time, the sealing sleeve 71 presses the sealing sleeve 72 against the end face of the outer sleeve 33, ensuring a tight seal at the joint between the inner tube 32 and the outer sleeve 33.

[0031] Furthermore, the outer wall of the inner tube 32 is provided with scale lines 23 for conveniently observing the length of the inner tube 32 extending from the outer tube 33. An adjusting screw 81 is coaxially rotatably provided inside the outer tube 33. The adjusting screw 81 is threadedly connected to the end of the inner tube 32 extending into the outer tube 33, and an adjusting screw head 82 is fixedly provided at the end of the screw away from the inner tube 32. An anti-slip structure can be provided between the inner tube 32 and the outer tube 33. The anti-slip structure includes an anti-slip step protruding from the end of the inner tube 32 extending into the outer tube 33, and a limiting step for adapting to the anti-slip step is provided on the end surface of the outer tube 33 from which the inner tube 32 extends. A guide block can be protruded from the anti-slip step, and a chute coaxially provided on the inner wall of the outer tube 33 is adapted to adapt to the guide block. The guide block is embedded in the chute, allowing the inner tube 32 to slide coaxially relative to the outer tube 33. After the adjusting tube 3 is removed from the connecting joint 1 and the connecting tube 2, the adjusting screw 82 can be operated from the end on the side where the outer sleeve 33 is located. By adjusting the screw 82, the inner tube 32 can be coaxially slid relative to the outer sleeve 33 to achieve fine adjustment of the extended length of the inner tube 32.
