Description

Technical Field

[0001] The invention relates to the technical field of crack control structures, and in particular to a crack control structure and a control method for an underground garage. Background Art

[0002] An underground garage is a building facility that provides storage space for cars. It is usually located below the ground and is one of the common supporting facilities in modern cities. With the increase in urban population and the popularity of cars, underground garages have become an important way to solve the problem of urban parking. The ground of the underground garage needs to be poured with concrete in order to build a strong, stable and durable ground structure. After the concrete is poured on the ground of the underground garage, the concrete needs to be insulated, especially when it is constructed in a low temperature environment. This is because during the solidification and hardening process of the concrete, if the temperature drops too quickly, cracks will appear.

[0003] Existing thermal insulation devices generally achieve the effect of controlling the temperature of concrete by setting a sealing plate and setting circulating water inside the sealing plate, and by contacting the sealing plate with the concrete after pouring. However, the concrete is generally smoothed after pouring. This step is crucial to ensure that the ground is flat, beautiful and solid. However, the direct contact between the sealing plate and the concrete after smoothing will make the smoothed concrete uneven again. However, there is a gap between the sealing plate and the concrete, and the sealing plate cannot directly contact the concrete, which will lead to insufficient heat exchange efficiency. Summary of the invention

[0004] The purpose of the present invention is to address the problem mentioned in the background technology that there is a gap between the sealing plate and the concrete, and the sealing plate and the concrete cannot be in direct contact, which leads to insufficient heat exchange efficiency. A crack control structure and control method for an underground garage is proposed, which maintains a certain gap between the sealing plate and the concrete but can accelerate the heat exchange efficiency.

[0005] On the one hand, the present invention provides a crack control structure for an underground garage, comprising two first baffles and two second baffles, and further comprising:

[0006] A plurality of insulation plates fixedly mounted between the two first baffles, wherein an insulation cavity is provided in the insulation plates, and an insulation mechanism is mounted on one side of the first baffle, wherein the insulation mechanism includes an insulation liquid, and the insulation mechanism controls the temperature of the insulation liquid and circulates the insulation liquid;

[0007] The air circulation mechanism is installed on the second baffle plate, and the air circulation mechanism increases the flow speed of the air in the gap between the thermal insulation board and the concrete, and enables the air to quickly exchange heat with the thermal insulation board.

[0008] Optionally, the insulation mechanism includes a water tank movably mounted on one side of the second baffle and a water pump fixedly mounted on the water tank, the input end of the water pump is connected to the water tank and extends to the bottom of the water tank, a reflux hole is provided on the water tank, an insulation cavity is provided in the insulation board, a first interface and a second interface are provided on one side of the insulation board, the first interface and the second interface are both connected to the insulation cavity, the output end of the water pump is connected to the first interface, and the second interface is connected to the reflux hole.

[0009] Optionally, a heating wire and a thermometer are fixedly installed in the water tank, the heating wire is located at the bottom of the water tank, and the thermometer is located at the top of the water tank.

[0010] Optionally, the air circulation mechanism includes a plurality of fans fixedly mounted on one of the second baffles, a plurality of air holes are provided on the second baffle, the air holes on two of the second baffles are connected by an air pipe, and a heat exchange component is provided on the insulation plate.

[0011] Optionally, the water tank is provided with a plurality of heat exchange holes, and the air pipes connected to the air holes on the two second baffles pass through the heat exchange holes.

[0012] Optionally, the heat exchange assembly includes a plurality of arc tubes fixedly mounted on the insulation plate, the arc tubes passing through one side of the insulation plate and extending into the interior of the insulation plate, the bottom of the arc tubes being located at the bottom of the insulation plate, and a plurality of stirring blades being fixedly mounted in the arc tubes.

[0013] Optionally, the stirring blades include a plurality of groups of support plates fixedly mounted in the arc tube, the support plates are provided with flow holes, a rotating shaft is rotatably mounted on one group of the support plates, and a plurality of fan blades are fixedly mounted on the rotating shaft.

[0014] Optionally, an impeller is rotatably installed in the heat preservation chamber, and the impeller is located in the middle of the heat preservation chamber.

[0015] Optionally, a heat-insulating tile is fixedly mounted on the top of the heat-insulating board, and a copper plate is used on the bottom of the heat-insulating board.

[0016] On the other hand, the present invention provides a crack control method for an underground garage, which is applied to the crack control structure of the above underground garage. The method comprises the following steps:

[0017] Step 1: Divide the pouring area into multiple parts for segmented pouring;

[0018] Step 2: construct a first baffle and two second baffles in the pouring area, so that the first baffle and the two second baffles enclose the pouring area;

[0024] Furthermore, the air flow efficiency can be increased by the air circulation mechanism, and the heat exchange efficiency can be increased. The circulating air will enter the interior of the arc tube and contact with multiple stirring blades. The stirring blades are driven to rotate by the air flow. The stirring blades stir the air, which can improve the uniformity of the air temperature. Since the arc tube is located inside the insulation chamber, the arc tube is in direct contact with the insulation liquid, so that the air passing through the arc tube can quickly exchange heat with the insulation liquid, so that the temperature of the air and the insulation board can be kept equal, and the heat exchange efficiency of the air and the insulation liquid can be improved. This ensures that the temperature of the concrete and the utilization rate of the heat of the insulation liquid are guaranteed without the insulation board being in direct contact with the concrete.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Example

[0035] like Figure 1-4 As shown, on one hand, the present invention proposes a crack control structure for an underground garage, including two first baffles 1 and two second baffles 101. First, the first baffle 1 and the second baffle 101 are built around the pouring area, and the pouring area is insulated by the first baffle 1 and the second baffle 101. After the construction is completed, pouring can be carried out in the first baffle 1 and the second baffle 101. It also includes a plurality of insulation boards 2 fixedly installed between the two first baffles 1. After the pouring is completed and the concrete surface is smoothed, the insulation board 2 can be installed on the first baffle 1. An insulation cavity 201 is provided in the insulation board 2, and an insulation mechanism is installed on one side of the first baffle 1. The insulation mechanism includes an insulation liquid, and the insulation mechanism controls the temperature of the insulation liquid and circulates the insulation liquid. By circulating the insulation liquid through the insulation mechanism, the temperature in the insulation cavity 201 can be kept constant, and the temperature of the insulation board 2 can be guaranteed, thereby preventing the temperature of the insulation board 2 from changing, and then preventing the concrete from having a large temperature change, thereby avoiding the cracking of the concrete during the solidification process.

[0036] Furthermore, the insulation mechanism includes a water tank 302 movably installed on one side of the second baffle 101, and a water pump 303 fixedly installed on the water tank 302, the input end of the water pump 303 is connected to the water tank 302 and extends to the bottom of the water tank 302, a reflux hole 304 is provided on the water tank 302, an insulation cavity 201 is provided in the insulation board 2, a first interface 3 and a second interface 301 are provided on one side of the insulation board 2, the first interface 3 and the second interface 301 are both connected to the insulation cavity 201, the output end of the water pump is connected to the first interface 3, and the second interface 301 is connected to the reflux hole 304. The insulation liquid in the water tank 302 is pumped out by the water pump 303, and the insulation liquid is transported to the insulation cavity 201 inside the insulation board 2, and the insulation liquid in the insulation cavity 201 is sucked out, so that the insulation liquid in the insulation cavity 201 flows back to the water tank 302 again, and the insulation liquid is heated inside the water tank 302, so that the insulation liquid can maintain a constant temperature and circulate inside the insulation cavity 201, so that the temperature of the insulation board 2 is maintained constant, and then the temperature of the gap between the insulation board 2 and the concrete is maintained in a relatively stable state, and the insulation board 2 will not directly contact the concrete, thereby preventing the insulation board 2 from damaging the unsolidified concrete, so that the concrete can remain flat and avoid secondary processing of the concrete.

[0037] Among them, a heating wire and a thermometer are fixedly installed in the water tank 302, the heating wire is located at the bottom of the water tank 302, and the thermometer is located at the top of the water tank 302. The insulation liquid can be heated by the heating wire, and the temperature of the insulation liquid can be measured by the thermometer, which is convenient for controlling the temperature of the insulation liquid.

[0038] Among them, an impeller 305 is rotatably installed in the insulation chamber 201, and the impeller 305 is located in the middle of the insulation chamber 201. When the insulation liquid flows in the insulation chamber 201, the heat of the insulation liquid will be gradually damaged, especially the part directly in contact with the inner wall of the insulation chamber 201, which is easy to cause the problem of uneven temperature of the insulation liquid. When the insulation liquid passes through the impeller 305, the impeller 305 will rotate under the drive of the insulation liquid, and the rotating impeller 305 will stir the insulation liquid, so that the insulation liquids at different levels are mixed with each other, thereby increasing the heat utilization rate of the insulation liquid and preventing the occurrence of uneven temperature in the insulation chamber.

[0039] Furthermore, a heat-insulating tile is fixedly installed on the top of the heat-insulating board 2, and a copper plate is used at the bottom of the heat-insulating board 2. The heat-insulating tile at the top reduces the speed at which heat in the heat-insulating cavity 201 is lost to the outside air, while the copper plate at the bottom has good thermal conductivity, thereby increasing the heat exchange efficiency at the bottom.

[0040] like Figure 3-7As shown, the air circulation mechanism is installed on the second baffle 101. The air circulation mechanism increases the flow rate of the air in the gap between the insulation board 2 and the concrete, and allows the air to quickly exchange heat with the insulation board 2. The air circulation mechanism includes a plurality of fans 4 fixedly installed on one of the second baffles 101. The second baffle 101 is provided with a plurality of air holes 401. The air holes 401 on the two second baffles 101 are connected by an air pipe, and a heat exchange component is provided on the insulation board 2. The air in the gap between the insulation board 2 and the concrete can be circulated through the air holes 401 by the fan 4, thereby increasing the flow efficiency of the air and increasing the heat exchange efficiency. The heat exchange component includes a plurality of arc tubes 5 fixedly installed on the insulation board 2. The arc tubes 5 penetrate one side of the insulation board 2 and extend to the inside of the insulation board 2. The bottom of the arc tubes 5 is located at the bottom of the insulation board 2. A plurality of stirring blades are fixedly installed in the arc tubes 5. The circulating air will enter the arc tube 5 and contact with multiple stirring blades. The stirring blades are driven to rotate by the flow of air. The stirring blades stir the air to improve the uniformity of the air temperature. Since the arc tube 5 is located inside the insulation chamber 201, the arc tube 5 is in direct contact with the insulation liquid, so that the air passing through the arc tube 5 can quickly exchange heat with the insulation liquid, so that the temperature of the air and the insulation board 2 can be kept equal, and the heat exchange efficiency of the air and the insulation liquid can be improved. This ensures that the insulation board 2 does not directly contact the concrete, and the concrete temperature and the utilization rate of the insulation liquid heat are guaranteed.

[0041] Furthermore, the stirring blade includes a plurality of support plates 501 fixedly mounted in the arc tube 5, the support plates 501 are provided with flow holes 502, a rotating shaft 503 is rotatably mounted on a group of support plates 501, and a plurality of fan blades 504 are fixedly mounted on the rotating shaft 503. The fan blades 504 can be driven to rotate when air passes through the fan blades 504, and the rotating fan blades 504 will stir the air to make the temperature of the air more uniform.

[0042] The water tank 302 is provided with a plurality of heat exchange holes 402, and the air pipes connected to the air holes 401 on the two second baffles 101 pass through the heat exchange holes 402. The circulating air can pass through the heat exchange holes 402, which can further ensure the stability of the air temperature.

[0043] Another aspect of the present invention provides a crack control method for an underground garage, using the above crack control structure for an underground garage, the method comprising the following steps:

[0044] Step 1: Divide the pouring area into multiple parts for segmented pouring;

[0045] Step 2: construct a first baffle 1 and two second baffles 101 in the pouring area, so that the first baffle 1 and the two second baffles 101 enclose the pouring area;

[0046] Step 3: pouring the area enclosed by the first baffle 1 and the two second baffles 101, and smoothing it after pouring;

[0047] Step 4: Install the insulation board 2 on the first baffle 1, heat the insulation liquid in the water tank 302, and circulate the insulation liquid in the insulation board 2 through the insulation mechanism;

[0048] Step 5: Start the air circulation mechanism to circulate the air in the gap between the insulation board 2 and the concrete, and speed up the heat exchange rate between the air and the insulation board 2, so that the heat on the insulation board 2 is quickly transferred to the concrete.

[0049] Working principle: First, build the first baffle 1 and the second baffle 101 around the pouring area. After the construction is completed, pouring can be carried out inside the first baffle 1 and the second baffle 101. After the pouring is completed and the concrete surface is smoothed, the insulation board 2 can be installed on the first baffle 1. The insulation liquid in the water tank 302 is extracted by the water pump 303, and the insulation liquid is transported to the insulation cavity 201 inside the insulation board 2, and the insulation liquid in the insulation cavity 201 is sucked out, so that the insulation liquid in the insulation cavity 201 flows back to the water tank 302 again, and the insulation liquid is heated inside the water tank 302, so that the insulation liquid can maintain a constant temperature and circulate inside the insulation cavity 201, so that the temperature of the insulation board 2 is kept constant, and then the temperature of the gap between the insulation board 2 and the concrete is kept in a relatively stable state, and the insulation board 2 will not directly contact the concrete, thereby preventing the insulation board 2 from damaging the unsolidified concrete, so that the concrete can be kept flat, and avoid secondary processing of the concrete. The air in the gap between the insulation board 2 and the concrete can be circulated through the air holes 401 by the fan 4, thereby increasing the air flow efficiency and the heat exchange efficiency. The circulating air will enter the arc tube 5 and contact with multiple stirring blades. The stirring blades are driven to rotate by the flow of air. The stirring of the air by the stirring blades can improve the uniformity of the air temperature. Since the arc tube 5 is located inside the insulation chamber 201, the arc tube 5 is in direct contact with the insulation liquid, so that the air passing through the arc tube 5 can quickly exchange heat with the insulation liquid, so that the temperature of the air and the insulation board 2 can be kept equal, and the heat exchange efficiency of the air and the insulation liquid can be improved. Thereby, it is ensured that the temperature of the concrete and the utilization rate of the heat of the insulation liquid are guaranteed without the insulation board 2 being in direct contact with the concrete.
