Description

Technical Field

[0001] The invention relates to an improvement of a constant temperature curing system, and in particular to a constant temperature heating curing system for concrete during winter construction. Background Art

[0002] In winter, in order to reduce the impact of low temperature on concrete solidification, concrete construction usually uses a constant temperature heating system to cover the semi-solidified concrete. For example, a felt with an electric heating resistor wire is usually used to cover the surface of the concrete. Generally, the felt is of fixed length, so multiple constant temperature heating systems need to be spliced ​​at the actual construction site to completely cover the concrete surface. The common constant temperature heating system is generally composed of a felt with a heating resistor wire. When in use, the felt is directly laid flat on the concrete surface, and the resistance wire can be energized for heating. The felt can not only play a role in heat preservation, but also evenly heat the resistance wire, and evenly heat the concrete surface. However, this kind of felt is generally limited in length, and it needs to be spliced ​​when covering a large area of ​​concrete. The general splicing method of felt is to overlap the head and tail. At the joint, two layers of felt are usually overlapped. The insulation effect here is stronger than other parts, so the temperature here is higher than other places, resulting in uneven heating of the concrete, affecting the coagulation effect of the concrete. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a constant temperature heating and curing system for concrete construction in winter.

[0004] The present invention is implemented by the following technical scheme: a constant temperature heating curing system for winter construction concrete, comprising a heating component, a connecting component and a temperature control component, wherein adjacent heating components are connected by connecting components, and the temperature control component is electrically connected to the connecting component; The connecting component includes a plug-in part and an energy supply part, the plug-in part is used to connect the adjacent heating components, the energy supply part is electrically connected to the plug-in part, and the temperature control component is electrically connected to the energy supply part.

[0005] By adopting the above technical solution, when two adjacent felts are spliced ​​together, the position of the connecting component can be adjusted so that the edges of the two adjacent felts can be spliced ​​together without overlapping, and only a seam is formed at the joint without overlapping, thereby reducing the possibility of heat accumulation at the joint. When in use, the concrete surface is heated more evenly, reducing the possibility of concrete deformation.

[0006] Optionally, the heating component includes a felt and a heating resistor, and the heating resistor is placed in the felt and evenly distributed in the felt; The end of the heating resistor is provided with a receiving part connected to the plug-in part, and the plug-in part and the receiving part are detachably connected. When the plug-in part and the receiving part are connected, the temperature control component, the energy supply part, the plug-in part and the heating resistor form a loop.

[0007] By adopting the above technical solution, the felt is connected by the receiving part and the plug-in part after being laid, and the receiving parts are set at both ends of the felt, so that the felt can be connected in a forward direction from head to tail, and the heating resistors of the plug-in part and the receiving part are connected in series.

[0009] By adopting the above technical solution, the blocking member can be used to block the socket when it is not in use, so as to prevent foreign matter from entering the socket when it is not in use, thereby reducing the possibility of clogging of the socket during actual use.

[0010] Optionally, the plug-in part includes a socket, the socket is provided with a pair of plug-in poles, the plug-in poles are inserted into the receiving part, the energy supply part is arranged in the socket and electrically connected to the plug-in poles, the energy supply part is provided with an access hole, the end face of the access hole extends out of the socket and is flush with the socket, and the energy supply part is electrically connected to the temperature control component through the access hole.

[0011] By adopting the above technical solution, the plug-in column can be a copper column, which can be used as a fixing part and also as a connecting part of the circuit. After plugging in, the entire circuit can form a passage. At the same time, the fixing effect of the plug-in column can be used to fix the positions of adjacent felts. Only one seam is formed between the felts and they will not overlap, thereby reducing the accumulation of high temperature and making the concrete heating more uniform.

[0012] Optionally, the energy supply unit includes a circuit board, on which a transformer circuit is provided, and the transformer circuit converts the voltage input by the temperature control component into a rated voltage.

[0013] By adopting the above technical solution, when more felts are connected in series, the voltage transformation circuit will appropriately transform the voltage according to the number of actually connected felts, so that the heating state of all felts is more uniform.

[0014] Optionally, the temperature control component includes a switching part and a switching switch, the switching part includes a first voltage divider and a second voltage divider, and the first voltage divider and the second voltage divider are respectively electrically connected to the energy supply part through the switching switch.

[0015] By adopting the above technical solution, the input voltage can be adjusted by switching the switch to different switching parts, and the input voltage is positively correlated with the heating value of the heating resistor. Therefore, different switching parts can be used to perform voltage transformation operations in different construction scenes, control the heating temperature of the felt, and adapt to different cement hardening processes, making the heat maintenance more adaptable.

[0019] By adopting the above technical solution, the actual input voltage will be different as the switching mode is different, and the input voltage can be adjusted to adjust the temperature by adjusting the input voltage, thereby achieving the purpose of regulating the temperature.

[0020] Optionally, the blocking member includes a sealing plate, one end of which is rotatably connected to the inner wall of the socket, and a torsion spring is provided at the connection between the sealing plate and the socket, the torsion spring pushes the other end of the sealing plate to abut against the inner wall of the socket to close the socket, and the sealing plate is pushed to rotate when the plug-in part is inserted.

[0021] By adopting the above technical solution, when the sealing plate is not in use, the sealing plate is pushed to its edge to directly abut against the socket under the action of the torsion spring, that is, the socket is in a closed state when not in use. At the same time, the sealing plate can be pushed as long as it is inserted into the socket to make the sealing plate rotate. At the same time, after insertion, the sealing plate can also play a role of abutment and limiting, making the insertion tighter.

[0022] Optionally, the heating resistors are evenly distributed in the felt in an S shape.

When in use, the concrete surface is heated more evenly, reducing the possibility of concrete deformation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] Reference Figure 1-3 A constant temperature heating and curing system for winter construction concrete includes a heating component 3, a connecting component and a temperature control component. Adjacent heating components 3 are connected through the connecting component, and the temperature control component is electrically connected to the connecting component. The connecting component includes a plug-in portion 1 and an energy supply portion 2. The plug-in portion 1 is used to connect adjacent heating components 3. The energy supply portion 2 is electrically connected to the plug-in portion 1, and the temperature control component is electrically connected to the energy supply portion 2. When two adjacent felts 31 are spliced ​​together, the position of the connecting component can be adjusted so that the edges of the two adjacent felts 31 can be spliced ​​together without overlapping, and only a seam is formed at the joint without overlapping, thereby reducing the possibility of heat accumulation at the joint. When in use, the concrete surface is heated more evenly, reducing the possibility of concrete degeneration.

[0028] One implementation of the heating component 3 is that the heating component 3 includes a felt 31 and a heating resistor 32, and the heating resistor 32 is placed in the felt 31 and evenly distributed in the felt 31. Specifically, the heating resistors are evenly distributed in the felt 31 in an S shape. The end of the heating resistor 32 is provided with a receiving portion 4 connected to the plug-in portion 1, and the plug-in portion 1 and the receiving portion 4 are detachably connected. When the plug-in portion 1 and the receiving portion 4 are connected, the temperature control component, the energy supply portion 2, the plug-in portion 1 and the heating resistor 32 form a loop. After the felt 31 is laid, the receiving portion 4 is connected to the plug-in portion 1, and the receiving portion 4 is provided at both ends of the felt 31, so that the felt 31 can be connected head to tail in a forward direction, and the plug-in portion 1 and the receiving portion 4 are connected in series. The heating resistors in each felt 31 can be powered on to generate heat, so that the heating effect is more balanced. That is, both felts 31 have a receiving portion 4. When in use, the ends of the two felts 31 are first aligned but the two felts 31 are not overlapped, and then the receiving portions 4 on each felt 31 are opposite to each other, and then the plug-in portion 1 is inserted between the two receiving portions 4 to form a connection mode of receiving portion 4→plug-in portion 1→receiving portion 4. On the one hand, the heating resistor 32 in the felt 31 is directly electrically connected. At the same time, by utilizing the matching relationship between the plug-in portion 1 and the receiving portion 4, the gaps of the two adjacent felts 31 are opposite to each other and fixed by the plug-in portion 1 and the receiving portion 4 to form a whole. And because the heating resistors 32 are already connected in series with each other, they can be powered centrally.

[0029] In addition to the fixing function, the receiving part 4 also needs to serve the function of power supply. The receiving part 4 includes a terminal 41, and a socket 42 adapted to the plug-in part 1 is provided on the end surface of the terminal 41. A blocking member 43 is provided in the socket 42. When the plug-in part 1 is not plugged into the socket 42, the blocking member 43 closes the socket 42. When the socket 42 is not in use, the blocking member 43 can be used to block the blocking member 43 to prevent foreign matter from entering the socket 42 when the socket 42 is not in use, thereby reducing the possibility of clogging the socket 42 during actual use. The blocking member 43 includes a sealing plate 431, one end of the sealing plate 431 is rotatably connected to the inner wall of the socket 42, and a torsion spring is provided at the connection between the sealing plate 431 and the socket 42. The torsion spring pushes the other end of the sealing plate 431 to abut against the inner wall of the socket 42 to close the socket 42, and pushes the sealing plate 431 to rotate when the plug-in part 1 is inserted. When not in use, the sealing plate 431 is pushed to its edge to directly abut against the insertion hole 42 under the action of the torsion spring, that is, the insertion hole 42 is in a closed state when not in use. At the same time, the sealing plate 431 can be pushed as long as it is inserted into the insertion hole 42, so that the sealing plate 431 rotates. At the same time, after insertion, the sealing plate 431 can also play a role of abutment and limiting, making the insertion tighter.

[0030] The plug-in part 1 includes a plug-in socket 11, on which a pair of plug-in posts 12 are provided, and the plug-in posts 12 are inserted into the receiving part 4. The energy supply part 2 is arranged in the plug-in socket 11 and is electrically connected to the plug-in posts 12. The energy supply part 2 is provided with an access hole 21, and the end face of the access hole 21 extends out of the plug-in socket 11 and is flush with the plug-in socket 11. The energy supply part 2 is electrically connected to the temperature control component through the access hole 21. The plug-in posts 12 can be copper posts, which can be used as a fixing part and also as a connecting part of the circuit. After plugging, the entire circuit can form a path. At the same time, the fixing effect of the plug-in posts 12 is used to fix the positions of adjacent felts 31. Only one seam is formed between the felts 31, and they will not overlap, which reduces the state of high temperature accumulation and makes the concrete heating more uniform. The energy supply part 2 includes a circuit board 22, on which a transformer circuit is provided, and the transformer circuit converts the voltage input by the temperature control component to the rated voltage. When the number of felts 31 connected in series increases, the voltage transformer circuit appropriately transforms the voltage according to the number of actually connected felts 31, so that the heating state of all felts 31 is relatively uniform. When a single felt 31 is used, the temperature control component is directly connected to the corresponding receiving portion 4, and a single felt 31 can be used for covering, so as to adapt to different application occasions. The temperature control component is actually the power supply part of the whole system. One mode of the temperature control component is that the temperature control component includes a switching part 5 and a switching switch 53, and the switching part 5 includes a first voltage divider and a second voltage divider, and the first voltage divider and the second voltage divider are electrically connected to the energy supply part 2 through the switching switch 53. The switching switch 53 switches different switching parts 5 to adjust the input voltage, and the input voltage is positively correlated with the heat generation of the heating resistor. Therefore, different switching parts 5 can be used to perform voltage transformation operations in response to different construction scenes, control the heating temperature of the felt 31, and adapt to different cement hardening processes, so that the adaptability of heating maintenance is wider.

[0031] The first switching component includes a first voltage-dividing resistor 51, one end of which is provided with a first cut-in terminal, and the first voltage-dividing resistor 51 is cut in to supply power when the switching switch 53 contacts the first switching terminal. The voltage is divided by connecting resistors in series, and different voltage divisions are formed to adapt to different temperatures and more concrete hardening conditions. The second switching component includes a second voltage-dividing resistor 52, one end of which is provided with a second cut-in terminal, and the switching switch 53 rotates between the first switching terminal and the second switching terminal, and contacts the first switching terminal or the second switching terminal, and the resistance values ​​of the first voltage-dividing resistor 51 and the second voltage-dividing resistor 52 are different. With different switching modes, the actual input voltage will also be different, and the input voltage can be adjusted to adjust the temperature by adjusting the input voltage, so as to achieve the purpose of regulating the temperature.

[0032] When two adjacent felts 31 of the present invention are joined together, the position of the connecting assembly can be adjusted so that the edges of the two adjacent felts 31 can be joined together without overlapping, thereby only forming a joint without overlapping, reducing the possibility of heat accumulation at the joint, making the concrete surface more evenly heated during use, and reducing the possibility of concrete deformation.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
