[0002] Modern buildings often involve large-volume concrete construction, such as high-rise building foundations, large equipment foundations, water conservancy dams, etc. The main feature of large-volume concrete is its large volume. The surface coefficient of large-volume concrete is relatively small, the heat release of cement hydration is relatively concentrated, and the internal temperature rises relatively quickly. Therefore, when the temperature difference between the inside and outside of the concrete is large, temperature cracks will occur in the concrete, affecting the structural safety and normal use.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 7 As shown, the utility model provides a large-volume concrete seamless construction device, including a base plate 1 and a bracket 2. A temperature sensor is arranged on the top of the base plate 1. This is an existing mature technology and will not be described in detail here. An air inlet cavity 9 is opened inside the base plate 1. The air inlet cavity 9 is in a cross shape. A hot air blower 6 penetrating into the air inlet cavity 9 is installed in the middle of the base plate 1. An air guide plate 12 is fixedly connected to the inner bottom wall of the air inlet cavity 9. The air can be blown toward the four vents of the air inlet cavity 9 through the air guide plate 12, which plays a guiding role, thereby better controlling the bracket. 2 is fully heated. The bottom surface of the substrate 1 is provided with a plurality of ventilation holes 7 penetrating the air guide plate 12. Through the setting of the ventilation holes 7, part of the hot air blown out by the hot air blower 6 can be blown to the top of the concrete through the ventilation holes 7, and most of the other hot air will be blown to the surroundings through the inclined surface of the air guide plate 12, so that the heat is not only circulated above the concrete. The bottom surface of the substrate 1 is fixedly connected with four ventilation pipes 8 connected with the air inlet cavity 9. The hot air can be transported to the air inlet cavity 9 by the hot air blower 6 and discharged downward through each ventilation pipe 8. Four ventilation slots 13 corresponding to the ventilation pipes 8 are provided on the top of the support 2, and the ventilation pipes 8 are inserted into the ventilation slots 13. When the substrate 1 covers the support 2, the ventilation pipes 8 and the ventilation slots 13 can be connected, and the hot air in the air inlet cavity 9 is further transported to each ventilation slot 13. The bottom of each ventilation slot 13 is provided with an exhaust port 15 that penetrates to the outside of the support 2, so that after the hot air enters the exhaust port 15, it will be discharged from the opening at the bottom of the exhaust port 15, thereby achieving uniform concrete in the support 2 from bottom to top. Heating is performed to ensure that the temperature difference between the inside and outside is balanced, thereby solving the problem of insufficient heating of concrete. The inner wall of each exhaust port 15 is fixedly connected with a plurality of air guide plates 16. Through the setting of the air guide plates 16, when the hot air is blown to the exhaust port 15, it can avoid the hot air from being concentrated in the middle of the exhaust port 15, so that the exhaust port 15 can blow out the hot air comprehensively. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0026] like Figure 1 , Figure 7As shown, the left and right sides of the substrate 1 are fixedly connected with a transverse plate 41, and the left and right sides of the bracket 2 are fixedly connected with a positioning frame 43. The bottom surface of each transverse plate 41 is fixedly connected with a positioning rod 44 adapted to the inner wall of the positioning frame 43. A threaded tube 45 is threadedly sleeved on each positioning rod 44, and the threaded tube 45 is located at the bottom of the positioning frame 43. When the substrate 1 and the bracket 2 are combined, the positioning rod 44 will be stuck in the positioning frame 43 to position the substrate 1 and the bracket 2. When the substrate 1 is covered on the bracket 2, the threaded tube 45 will be rotated at this time to make the threaded tube 45 in the positioning The bottom end of the rod 44 rotates and moves upward, and contacts the positioning frame 43, thereby ensuring the stability between the substrate 1 and the bracket 2. An electric push rod 42 is installed on the bottom surface of each horizontal plate 41, and the bottom surface of each electric push rod 42 is fixedly connected to a moving frame 3. Through the arrangement of the electric push rod 42 and the moving frame 3, the substrate 1 can be pushed and moved conveniently, and the height of the substrate 1 can be controlled by the operation of the electric push rod 42, so as to facilitate covering the substrate 1 on the bracket 2. A handle is provided on the front of the substrate 1 to facilitate personnel to push the substrate 1 to move, and the operation is more convenient.

[0027] like Figure 1 , Figure 2 As shown, a fixed pipe 51 is fixedly connected to the base plate 1, and the fixed pipe 51 is sleeved on the outside of the hot air blower 6. A heat preservation cover 52 is threadedly sleeved on the fixed pipe 51. Through the setting of the above structure, when the concrete in the base plate 1 and the bracket 2 reaches the specified temperature, the operation of the hot air blower 6 can be stopped, and then the heat preservation cover 52 is tightened on the fixed pipe 51 to ensure that the external cold air will not enter the bottom of the base plate 1.

[0028] like Figure 3 , Figure 5 As shown, a sealing sleeve is fixedly connected to the corners of the bottom surface of the substrate 1, and a sealing ring that fits the sealing sleeve is fixedly connected to the corners of the upper surface of the bracket 2, so that when the substrate 1 and the bracket 2 are in contact, the sealing between the substrate 1 and the bracket 2 is guaranteed, thereby ensuring the heating and heat preservation effect on the concrete.

[0029] like Figure 3 , Figure 5 As shown, positioning grooves 10 are provided at the four corners of the bottom surface of the substrate 1, and positioning columns 14 adapted to the positioning grooves 10 are fixedly connected to the four corners of the upper surface of the bracket 2. Through the arrangement of the positioning grooves 10 and the positioning columns 14, the substrate 1 can play a guiding and positioning role when it is covered on the bracket 2.

[0030] like Figure 4 , Figure 6As shown, the interior of the substrate 1 and the interior of the bracket 2 are respectively provided with a first insulation cavity 11 and a second insulation cavity 17. By setting the first insulation cavity 11 and the second insulation cavity 17, the substrate 1 and the bracket 2 can have an insulation effect. The first insulation cavity 11 and the second insulation cavity 17 are filled with insulation cotton, which has a good insulation effect on the concrete in the bracket 2.

[0031] The working principle and use process of the utility model are as follows: first, the bracket 2 is placed outside the concrete, and then the base plate 1 is pushed to the top of the bracket 2, and the electric push rod 42 is used to lower the base plate 1 to fit with the bracket 2, and then the heat preservation cover 52 is removed, and the hot air blower 6 is started, and the hot air blower 6 is used to transport the hot air to the air inlet chamber 9. At this time, part of the hot air will be discharged downward to the top of the concrete through the ventilation hole 7 to heat it, and with the guidance of the air guide plate 12, the hot air will be blown toward the four ventilation pipes 8 to each ventilation slot 13, and discharged through the opening at the bottom of the exhaust port 15, so that the concrete is evenly heated from bottom to top, and the four sides of the concrete can be heated to ensure that the temperature difference between the inside and the outside is balanced, thereby solving the problem of insufficient heating of the concrete.
