Description

Technical Field

[0001] The utility model relates to a concrete heat preservation device, in particular to a prefabricated heat preservation board and a heat preservation system. Background Art

[0002] Mass concrete refers to those large-volume concrete members in construction projects where the minimum size of the structural entity is not less than 1 meter. After the pouring of this kind of concrete, due to the high heat generated by the internal cement hydration reaction and the difficulty of heat dissipation, the internal temperature of the concrete may rise rapidly, resulting in relatively large temperature stress. Therefore, it is necessary to avoid large temperature differences between the center and the surface of the mass concrete during the hydration process of the cementitious materials through heat preservation and curing to prevent temperature difference cracks.

[0003] Common heat preservation measures mainly involve using heat preservation materials (such as XPS boards) to cover the surface of the concrete structure. Through heat preservation, the rate of temperature drop of the concrete is reduced, making the temperature gradient distribution inside the concrete more uniform, ensuring that the curing environment of the mass concrete meets the strength formation requirements, and ensuring the construction quality of the concrete.

[0004] Currently, the installation measure for heat preservation boards is still to fix the corners of single boards. Workers need to take an aerial work vehicle to the predetermined installation position of the heat preservation board, and then manually hold reinforcement equipment such as a pneumatic nail gun to drill holes around the single board to fix and install the board on the mass concrete. After the fixation of a single board is completed, the position of the aerial work vehicle is changed to install the heat preservation boards in the next area. However, this method is only applicable to small-area walls. For the heat preservation of the outer surface of mass concrete structures in water transportation and water conservancy projects such as ship locks, docks, and hubs, the installation method of single boards will result in too many holes on the surface of the mass concrete, affecting the quality of the mass concrete. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the existing installation method of concrete heat preservation boards is not applicable to mass concrete and will result in too many holes on the surface of the mass concrete, affecting the quality of the mass concrete, and to provide a prefabricated heat preservation board and a heat preservation system.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A prefabricated heat preservation board includes a heat preservation board body and a keel. The keel is used to fix the heat preservation board body. The keel includes a frame and rib plates. The frame is a steel section member. The rib plates include flat iron members and steel section members. The rib plates are all connected to the inside of the frame. The size of the keel is greater than or equal to 2.5 m and less than or equal to 3 m.

[0008] The keel is a kind of building material used to support the shape and fix the structure. The insulation board body of the device is fixed to the keel, so when insulating the large volume of concrete, it is only necessary to fix the frame of the keel to the surface of the large volume of concrete. And the size of the keel is between 2.5m and 3m, so multiple insulation board bodies can be fixed to the keel, and it is also suitable for the height of each layer of concrete layered pouring. Compared with the prior art that a single board is fixed by punching holes around it, the device punches holes on the keel to fix multiple insulation board bodies, and can directly fix and then fix the keel to the surface of the large volume of concrete. Punching holes on the keel to fix multiple insulation board bodies can reduce the number of holes punched on the surface of the large volume of concrete, and avoid as much as possible the adverse effects on the quality and appearance of the large volume of concrete due to too many holes punched on the concrete surface. And compared with directly using a large area of ​​insulation board body, the use of keels in this device can avoid deformation of large-area insulation boards as much as possible, and can ensure the insulation effect as much as possible. And if it is necessary to locally check the state of the concrete or carry out repair work, small pieces of insulation board can be more easily removed and reinstalled without much impact on the overall insulation system. Using steel as the frame of the keel can be used as a hoisting component of the device, and can also be used as a handle when the component is manually transported, which is convenient for the insulation covering operation of the bottom layer of the structure. Flat iron is used as the ribs of the keel, which can reinforce the keel and support the insulation board. And this device can be directly hoisted to the predetermined position during the construction process. Compared with a single board that requires an aerial work vehicle to hold the insulation board to the predetermined position, the positioning process of a single board is reduced. And it can be prefabricated directly in the factory, which can also reduce the number of holes, so it can improve construction efficiency.

[0009] As a preferred solution of the utility model, the keel is provided with a hoisting piece.

[0010] The keel is equipped with a hoisting piece, so when installing this component to a large concrete surface, the device can be directly hoisted to the predetermined position, which is convenient for installation.

[0011] As a preferred solution of the utility model, both ends of the hanging piece are respectively connected to the steel structure, and the distance from the hanging piece to the center of the frame is greater than 0.

[0012] The two ends of the hoisting piece can be connected to the steel structure of the rib plate and the steel structure of the frame respectively; or both ends can be connected to the steel structure of the rib plate. If the distance from the hoisting piece to the center of the frame is greater than 0, the frame will not be horizontal during hoisting, and the insulation board body will be prevented from falling off the keel during hoisting as much as possible, which is conducive to improving construction efficiency.

[0013] As a preferred solution of the utility model, the frame is a rectangular member, the flat iron member of the rib plate is perpendicular to the steel member of the rib plate, there are at least two hanging parts, and the connecting line of the two hanging parts is parallel to one side of the frame.

[0014] There are two lifting members, so that stress concentration can be avoided as much as possible during lifting, and damage to the structure can be avoided as much as possible. The connection line of the lifting members is parallel to the frame, so that the forces on the two lifting members are as equal as possible during lifting, which is beneficial to improving the safety of lifting.

[0015] As a preferred solution of the present utility model, the heat preservation board body is connected to the outside of the frame.

[0016] The outside of the frame is the side of the flat structure composed of keels facing away from the rib plate. In this way, it is convenient to connect

[0017] A heat preservation system includes a flexible heat preservation member and an assembled heat preservation board as described above. The flexible heat preservation member can be used to cover the curved concrete block.

[0018] By setting the flexible heat preservation member, the curved concrete can be covered as tightly as possible, and the temperature loss of the curved concrete can be reduced as much as possible. It is applicable to large-volume concrete with curved surfaces such as ship locks.

[0019] As a preferred solution of the present utility model, it further includes a temperature sensor, a controller and an alarm.

[0020] The temperature sensor is connected to the controller. The temperature sensor is used to detect the temperatures of the surface and the center of the large-volume concrete and send signals to the controller;

[0021] The controller is used to receive the signals sent by the temperature sensor and calculate the temperature difference between the surface and the center of the large-volume concrete;

[0022] When the temperature difference exceeds the threshold value, the controller sends a signal to the alarm. The alarm receives the signals sent by the temperature sensor and issues an alarm.

[0023] The temperature difference between the center and the surface of the large-volume concrete cannot be too large, otherwise cracking will occur. Therefore, a temperature sensor is set to monitor the temperatures of the surface and the center of the large-volume concrete in real time, and a controller is used to calculate the temperature difference. When the temperature difference exceeds the threshold value, the alarm will issue an alarm, which is convenient for subsequent adjustment.

[0024] As a preferred solution of the present utility model, the flexible heat preservation member is provided with Velcro.

[0025] If the flexible heat preservation member is provided with Velcro, the flexible heat preservation member can be directly pasted on the concrete surface without punching for fixation, and the adverse impact on the quality of the concrete caused by punching can be avoided as much as possible.

[0026] As a preferred solution of the present utility model, the flexible heat preservation member is a heat preservation blanket made of polyester fiber.

[0027] Polyester insulation blankets are strong, lightweight, durable and waterproof.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0029] 1. An assembled insulation board, the insulation board body is fixed to the keel, so when insulating a large volume of concrete, it is only necessary to fix the keel to the surface of the large volume of concrete. And if the size of the keel is greater than 2.5m, multiple insulation board bodies can be fixed to the keel. Compared with the prior art that a single board is fixed, directly fixing the keel can reduce the number of holes punched on the surface of the large volume of concrete, and avoid as much as possible the adverse effect on the quality of the large volume of concrete caused by too many holes punched on the concrete surface, solving the problem that the installation method of the concrete insulation board in the prior art is not suitable for large volume concrete, which will cause too many holes on the surface of the large volume of concrete to affect the quality of the large volume of concrete. Using steel as the frame of the keel can be used as a hoisting component of the device, and can also be used as a handle when the component is manually transported. Flat iron is used as the rib of the keel, which can reinforce the keel and support the insulation board. And the device can be directly hoisted to the predetermined position during the construction process, compared with the single board that requires an aerial work vehicle to hold the insulation board to the predetermined position, the positioning process of the single board is reduced. It can be prefabricated directly in the factory, which can also reduce the number of holes to be drilled, thus improving construction efficiency.
