Description

Technical Field

[0001] The present application relates to the field of concrete crack prevention, and in particular to a concrete crack prevention construction method based on temperature control and a construction device thereof. Background Art

[0002] Concrete releases a large amount of heat during the solidification process, but concrete itself is a poor conductor of heat, which causes heat to accumulate inside the concrete, resulting in a large temperature difference between the inside and outside. As a result, temperature cracks are likely to occur after the concrete solidifies. Temperature cracks seriously affect the integrity and durability of the concrete structure.

[0003] In the related art, before pouring concrete, a spiral condenser is buried in the concrete. The condenser is provided with a medium inlet and a medium outlet, and a water source station is built at the medium inlet of the condenser. When the concrete needs to be cooled, condensed water is circulated and injected into the condenser through the water source station to achieve the purpose of cooling.

[0004] For some longer pouring areas, such as roads, when laying condenser pipes, if the condenser pipes are too long, it is not convenient to transport and lay them. When the condenser pipes are shorter, more condenser pipes will be needed for the longer pouring area, which requires the construction of more water source stations and consumes more manpower and material resources. Summary of the invention

[0005] In order to facilitate the installation and transportation of condenser pipes while reducing the construction of water source stations, the present application provides a concrete anti-cracking construction method based on temperature control.

[0006] In the first aspect, the present application provides a concrete crack prevention construction method based on temperature control, which adopts the following technical solution:

[0007] A method for constructing a concrete crack-proof heat exchange tube based on temperature control comprises the following steps: step 1, installing a heat exchange tube in an area to be poured, wherein a medium inlet and a medium outlet of the heat exchange tube are both located outside the area to be poured; the heat exchange tube comprises a plurality of unit sections, wherein the unit sections comprise a starting section, a finishing section and a plurality of connecting sections, the medium inlet of the heat exchange tube is arranged on the starting section, the medium outlet of the heat exchange tube is arranged on the finishing section, one end of the starting section and the connecting section are both connected with a connecting tube 1, and the other end of the finishing section and the connecting section are both connected with a connecting tube 2, wherein the connecting tube 1 is used to be connected with the connecting tube 2; step 2, pouring concrete in the area to be poured; step 3, controlling the concrete temperature by injecting a heat exchange medium into the heat exchange tube.

[0008] By adopting the above technical solution, before pouring concrete, heat exchange tubes are arranged in the area to be poured. Therefore, after pouring concrete, if the temperature in the concrete structure is too high, a cooling medium (such as condensed water) can be injected into the heat exchange tubes. The cooling medium flows along the heat exchange tubes and flows out from the medium outlet, thereby taking out the heat in the concrete structure, thereby reducing the temperature of the concrete structure and improving the problem of temperature cracks easily generated in the concrete. In addition, for roads, in winter, the roads are prone to ice. At this time, a heating medium (such as steam) can be injected into the heat exchange tubes to heat the concrete structure, so as to melt the ice and snow on the road and make the road passable normally. By setting up heat exchange tubes and in the exchange The temperature of the concrete structure can be controlled by injecting heat exchange medium into the heat pipe; for the construction of a longer area to be poured (such as a road), the heat exchange pipe is arranged into multiple unit sections, and the unit section is composed of a starting section, a finishing section and multiple connecting sections, so that the heat exchange pipe can be installed section by section during construction, which is convenient for the transportation and installation of the heat exchange pipe. At the same time, the setting of multiple connecting sections is convenient for controlling the length of the unit section, and each unit section has a medium inlet and a medium outlet, which is convenient for the subsequent supply of heat exchange medium and the recovery of heat exchange medium; in addition, the starting section, the finishing section and multiple connecting sections can be connected through connecting pipe 1 and connecting pipe 2, so that the unit section forms a whole, reducing the medium inlet and the medium outlet, so as to reduce the construction of the water source station.

[0009] Optionally, the connecting tube 2 is used to be inserted into the connecting tube 1, an air ring is fixed on the inner wall of the connecting tube 1, the air ring is used to be sleeved on the connecting tube 2, and the connecting tube 1 is provided with an inflation component for inflating the air ring, and the air ring is inflated to press against the connecting tube 2.

[0010] By adopting the above technical solution, after connecting tube 2 is inserted into connecting tube 1, the air ring is inflated through the inflation component, so that the air ring can be expanded and pressed against connecting tube 2. Through the arrangement of the air ring and the inflation component, the connection between connecting tube 1 and connecting tube 2 has good sealing performance.

[0011] Optionally, the inflation component includes a piston block and a spring. An air groove is opened on the inner wall of the connecting tube one, and the piston block is inserted into the air groove. The spring has a tendency to cause the piston block to partially extend out of the air groove and enter the connecting tube one. The connecting tube two is inserted into the connecting tube one to push the piston block into the air groove, and the air groove is connected to the air ring.

[0012] By adopting the above technical solution, when connecting tube 2 is inserted into connecting tube 1, the piston will be pushed to move, so that the piston is inserted into the air groove, so that under the action of air pressure, the gas in the air groove enters the air ring, causing the air ring to expand; the inflation component has a simple structure and is easy to operate.

[0013] Optionally, a limiting rod is inserted into the inner wall of the connecting tube, and a limiting groove is provided on the inner wall of the connecting tube for the limiting rod to be fully inserted into. The limiting groove is connected to the air groove, and when the spring is not deformed, the limiting rod is completely located in the limiting groove; a slot is provided on the outer wall of the connecting tube for the limiting rod to be inserted into.

[0014] By adopting the above technical solution, during the process of connecting tube 2 being inserted into connecting tube 1, since the limiting rod is blocked by the outer wall of connecting tube 2 and will not move, the gas in the air groove will preferentially enter the air ring until the groove on the outer wall of connecting tube 2 moves to the position of the limiting rod. Then the limiting rod can move, so that the gas in the air ring will partially overflow, pushing the limiting rod into the groove, making it impossible for connecting tube 2 to separate from connecting tube 1, thereby enhancing the connection stability between connecting tube 2 and connecting tube 1.

[0015] In a second aspect, the present application provides a construction device using a concrete anti-cracking construction method based on temperature control, which adopts the following technical solution:

Through the setting of the installation mechanism, the supporting plate can carry the unit segment, and the conveying mechanism can install the unit segment on the supporting plate between two adjacent slide rails, which can reduce manpower and is a prerequisite for realizing automated construction. The setting of the installation rail is convenient for the sliding of the mobile frame on the one hand, and for the positioning of the unit segment on the other hand.

[0018] Optionally, the transport mechanism includes a slide seat which is arranged on a mobile frame and can move in a vertical direction, the mobile frame is provided with a driving component 1 for driving the slide seat to slide, the slide seat is rotatably connected to a material picking rack, the rotating axis of the material picking rack is arranged in a vertical direction, the slide seat is provided with a driving component 2 for driving the material picking rack to rotate, the material picking rack is provided with a cylinder, the telescopic end of the cylinder is fixedly connected to an electromagnetic suction cup, and the cylinder is telescopic so that the electromagnetic suction cup can grab the unit segment on the carrying plate.

[0019] By adopting the above technical solution, when installing the unit segment, the unit segment on the supporting plate is grabbed by the cylinder and the electromagnetic suction cup, and then the material picking rack is rotated by the driving component 2 to drive the cylinder to rotate, so that the unit segment grabbed by the cylinder is located above the two adjacent slide rails, and then the slide seat is driven downward by the driving component 1 to install the unit segment between the two installation rails; the transport mechanism has a simple structure and is easy to operate.

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application discloses a concrete crack prevention construction method based on temperature control. Figure 1 and Figure 2 , including the following steps:

[0037] Step 1: Level the area to be poured (in this embodiment, the area to be poured is road 1).

[0038] Step 2: construct multiple medium supply boxes 2 and medium recovery boxes 3 on both sides of the road 1. Adjacent medium supply boxes 2 and medium recovery boxes 3 are connected by a delivery pipe 6. A delivery pump 4 is installed on the delivery pipe 6. The delivery pump 4 is used to transport the medium in the medium recovery box 3 to the medium supply box 2.

[0039] Step 3, install the heat exchange tube 5 in the area to be poured, the medium inlet 7 and the medium outlet 8 of the heat exchange tube 5 are both located outside the area to be poured, the heat exchange tube 5 is wavy, the heat exchange tube 5 includes multiple unit sections 49, each unit section 49 is provided with a medium inlet 7 and a medium outlet 8, the number of medium supply boxes 2 and medium inlets 7 is the same, the number of medium recovery boxes 3 and medium outlets 8 is the same, the medium supply box 2 is connected to the medium inlet 7 through the medium inlet pipe 10, the medium recovery box 3 is connected to the medium outlet 8 through the medium outlet pipe 11, and a water pump 9 is installed on the medium inlet pipe 10, and the water pump 9 is used to transport the medium in the medium supply box 2 to the heat exchange tube 5.

[0040] The unit section 49 includes a starting section 12, a tail section 13 and multiple connecting sections 14. The medium inlet 7 of the heat exchange tube 5 is arranged on the starting section 12, and the medium outlet 8 of the heat exchange tube 5 is arranged on the tail section 13. One end of the starting section 12 and one end of the connecting section 14 are both connected with a connecting pipe 15, and one end of the tail section 13 and one end of the connecting section 14 away from the connecting pipe 15 are both connected with a connecting pipe 2 16. The connecting pipe 2 16 is used to be inserted into the connecting pipe 15 in the vertical direction, and the outer wall of the connecting pipe 2 16 is adapted to the inner wall of the connecting pipe 15.

[0041] When installing the heat exchange tube 5, first install the starting section 12, then install the connecting section 14, select a suitable number of connecting sections 14 as needed, install multiple connecting sections 14 one by one, and finally install the ending section 13. During this installation process, the connecting pipe 2 16 must be inserted into the connecting pipe 1 15 in the vertical direction.

[0042] The unit segment 49 is divided into a starting segment 12, an ending segment 13 and a plurality of connecting segments 14. When transporting and installing the unit segment 49, the unit segment 49 can be split to reduce the length of the unit segment 49, thereby facilitating the transportation and installation of the unit segment 49. When installing the unit segment 49, the unit segment 49 can be installed segment by segment, and during the installation process, the starting segment 12, the ending segment 13 and the plurality of connecting segments 14 are connected into a whole through connecting pipe 1 15 and connecting pipe 2 16, so as to facilitate the introduction of heat exchange medium into the entire unit segment 49.

[0043] Reference Figure 3 and Figure 4In order to make the connected unit segment 49 have better sealing performance, an annular groove 17 is opened on the inner wall of the connecting pipe 15, and an air ring 18 is fixed in the annular groove 17 (the air ring 18 can be fixed by gluing). The air ring 18 is used to be sleeved on the connecting pipe 2 16, and a rubber pad 19 is fixed inside the air ring 18 (the rubber pad 19 can be fixed by gluing). The connecting pipe 15 is provided with an inflation component for inflating the air ring 18, and the air ring 18 is inflated to make the rubber pad 19 press against the connecting pipe 2 16.

[0044] The inflatable assembly includes a piston block 20 and a spring 21. A fixing block 45 is fixedly connected to the outer wall of the connecting pipe 15 (the fixing method of the fixing block 45 can be welding). An air groove 22 is opened on the fixing block 45. The air groove 22 is connected to the inside of the connecting pipe 15. The air groove 22 is connected to the air ring 18 through the air pipe 23. The piston block 20 can be completely inserted into the air groove 22. The length direction of the spring 21 is arranged along the insertion direction of the piston block 20. When the spring 21 is not deformed, the piston block 20 is partially located in the connecting pipe 15, and the piston block 20 faces the connecting pipe 15. The portion of the opening located in the connecting tube 15 is an arc-shaped convex surface; due to the setting of the arc-shaped convex surface, when the connecting tube 16 is inserted into the connecting tube 15, the connecting tube 16 pushes the piston block 20 to completely enter the air groove 22, and the air groove 22 is connected to the air ring 18. When the piston block 20 enters the air groove 22, under the action of air pressure, the gas in the air groove 22 enters the air ring 18, causing the air ring 18 to expand, so that the rubber pad 19 is pressed against the connecting tube 15, thereby realizing the sealing of the connecting tube 15 and the connecting tube 2 16.

[0045] In order to prevent the connecting pipe 2 16 from being separated from the connecting pipe 1 15 before pouring concrete, a limiting rod 26 is inserted into the inner wall of the connecting pipe 1 15, and a limiting groove 25 (the limiting groove 25 is relatively small) is provided on the inner wall of the connecting pipe 15 for the limiting rod 26 to be fully inserted into. The limiting groove 25 is connected to the connecting pipe 15, and the limiting groove 25 is connected to the air groove 22 through the pipeline 28. When the spring 21 is not deformed, the limiting rod 26 is completely located in the limiting groove 25; a card slot 27 is provided on the outer wall of the connecting pipe 2 16 for the limiting rod 26 to be inserted into.

[0046] During the process of inserting the connecting tube 16 into the connecting tube 1 15 , the connecting tube 16 pushes the piston block 20 to completely enter the air groove 22 , and the gas in the air groove 22 first enters the air ring 18 , and the air ring 18 expands, causing the rubber pad 19 to press against the outer wall of the connecting tube 16 , until the groove 27 on the outer wall of the connecting tube 16 moves to the position of the limiting rod 26 . Under the action of air pressure, a very small part of the gas in the air ring 18 will enter the limiting groove 25 (without affecting the sealing effect of the air ring 18 ), pushing the limiting rod 26 in the limiting groove 25 to extend out of the limiting groove 25 and be inserted in the groove 27 , thereby completing the limiting of the connecting tube 16 and preventing the connecting tube 16 from being separated from the connecting tube 1 15 .

[0047] The implementation principle of the temperature-controlled concrete crack prevention construction method of the present application is as follows: before pouring concrete, a heat exchange tube 5 is arranged in the area to be poured. After pouring concrete, if the temperature inside the concrete structure is too high, a cooling medium (such as condensed water) can be injected into the heat exchange tube 5 through the medium supply box 2. The cooling medium flows along the heat exchange tube 5 and flows out from the medium outlet 8 to the medium recovery box 3, thereby taking out the heat in the concrete structure, thereby reducing the temperature of the concrete structure and improving the problem of temperature cracks easily occurring in the concrete.
