Description

Technical Field

[0001] The utility model relates to the field of concrete maintenance and is suitable for concrete thermal insulation molding in a low-temperature environment. Background Art

[0002] For buildings with normal construction schedules, construction in cold areas is suspended and workers go home for holidays. However, there is uncertainty in the time for changes to existing facilities and repairs of accidents. If outdoor construction is carried out during the low temperature period in winter, concrete must be poured, and insulation measures must be taken to avoid poor solidification of concrete at low temperatures and cracking and powdering when the temperature rises in spring. The current common practice is to use greenhouse methods or electric blankets or cotton blankets for covering. The former is suitable for large-scale concrete construction, but when it is applied to scattered projects or construction with small amounts of work, the cost is high and the heat waste is large. At the same time, the greenhouse method mostly uses raw coal for heating, which poses safety hazards of fire, poisoning, and suffocation; the latter, in order to ensure the pouring quality, needs to cover the concrete surface with electric blankets or cotton blankets at the beginning of concrete pouring, which can easily cause the concrete surface to become uneven, affecting the quality and appearance, and also causing the blanket to stick to the concrete surface, making it difficult to clean and unable to be reused. The applicant applied for a warm air heating device on the same day to solve the above problems. However, the length of the warm air duct would result in uneven air volume at different distances, so another electric heating wire heating structure was designed. The two structures were designed to observe the actual use effects and determine the optimal solution. Utility Model Content

DETAILED DESCRIPTION

[0015] An electric heating concrete insulation device comprises a support system, an insulation cloth, and an electric heating wire. The support system comprises a main support 1, a support shaft 3, a support vertical rod 4, and a support cross rod 6. The support cross rod 6 is at the top and is provided with a plurality of support vertical rods 4 in parallel. Two support vertical rods 4 are hinged at each end of the support cross rod 6, and the angle between the two support vertical rods 4 is an acute angle. The support vertical rods 4 are hinged at the intersection of the two and the bottom end through the support shaft 3. The plurality of support vertical rods 4 form a diamond telescopic structure, and the support vertical rods 4 on the edge of one side are hinged at the intersection of the two. The end is hinged on the inner wall of the main support 1, and the outermost support vertical rod 4 on the other side is hinged on the door frame 12. A hook 13 is fixed to the upper outer surface of the door frame 12, and the hook 13 is used to hang the curtain 14. The insulation cloth 15 covers and wraps around the support vertical rod 4 and the support cross rod 6 when the support system is opened. The extra length at the bottom touches the ground and sandbags or bricks are pressed on it. The electric heating wire 2 is a soft wire, which is tied to the support vertical rod 4 and the support cross rod 6, and a movable gap is left between the binding belt and the electric heating wire 2.

[0016] A curtain placement box 9 is provided on the top of the main frame 1, and the curtain placement box 9 is used to place the folded heat insulation cloth 15 and the curtain 14. The curtain placement box 9 is closed with an openable and closable box cover and a buckle. The heat insulation cloth 15 and the curtain 14 are made of fireproof fiber cloth to prevent the electric heating wire 2 from contacting and burning.

[0017] like Figure 3 As shown, a collar 16 is fixed on the top of the bracket vertical rod 4, and the collar 16 is sleeved on the bracket cross bar 6. The end of the bracket cross bar 6 has a stop cap 17 and a plurality of sockets 18. The sockets 18 are used to insert a stop sign 19. The stop sign 19 is non-fixedly connected to the socket 18 and can be pulled out when needed. The collar 16 slides on the bracket cross bar 6, and the stop sign 19 is inserted into the socket 18 to limit the bracket cross bar 6. The spacing between the bracket cross bars 6 on both sides can be adjusted. Different widths of the cast 5 can be applied to different widths, so that the space size is appropriate and will not cause heat waste due to being too large. The distance between the electric heating wire 2 and the cast 5 is appropriate, which can save electricity to a certain extent.

[0018] The bottom of the main frame 1 and the door frame 12 is fixed with a bracket bottom support 7, and the bracket bottom support 7 is provided with a bolt hole 8. The bolt hole 8 is fixed with a connecting nail, a screw is used for hardened ground (after removal, the screw hole is sealed with cement slurry tank injection), and an ordinary round nail or wooden wedge is used for non-hardened ground.

[0019] A fixing belt 11 is provided to bind the support system when the support system is folded, and to place the support system in the curtain placement box 9 when the support system is in use. Two fixing belts 11 can be used to bind the upper and lower parts and the left and right parts. The specific fastening form of the fixing belt 11 can be a perforated synthetic fiber belt with nail buckles.

[0020] As attached Figure 1 , 2 , 4 indicates that when not in use (such as Figure 1 ), and the fixing belt 11 is tied and fixed to prevent it from unfolding. When it is needed to use, one side of the device is fixed to the ground through the bottom support 7 and bolt hole 8 of the bracket. After the pouring, vibration and plastering of the casting 5 are completed, open the fixing belt 11, pull open the bracket vertical rod 4 and the bracket cross rod 6, and then open the curtain placement box 9, take out the curtain 14 and the insulation cloth 15, and hang the curtain 14 on the door frame 12. The insulation cloth 15 is placed on the periphery of the bracket vertical rod 4 and the bracket cross rod 6. Sandbags or masonry are pressed at the bottom to fix it to prevent wind from blowing, and the whole system is wrapped tightly, and the casting 5 is covered therein. The other side of the device is fixed to the ground through the bottom support 7 and bolt hole 8 of the bracket. The electric heating wire 2 is connected to the power supply, and the power switch is turned on. The heat is radiated through the electric heating wire 2 to the surrounding of the casting 5, so that the temperature is above zero degrees Celsius, and the concrete achieves a normal solidification effect to avoid low temperature frost damage.

[0021] When the construction is completed and the inspection is qualified, turn off the power switch, then recycle the curtain 14 and the heat insulation cloth 15 to the curtain cloth placement box 9; remove the bottom support 7 of the bracket from the ground, and then recycle the bracket vertical rod 4 and the bracket cross rod 6 to one side of the main bracket 1; use the fixing belt 11 to tie and fix the entire device (such as Figure 1 ) for next use.
