Description

Technical Field

[0001] This utility model relates to the field of concrete mold technology, and in particular to a temperature-adjustable concrete mold preheating device. Background Technology

[0002] Buildings assembled from precast components are called prefabricated buildings. With the development of prefabricated buildings, the market demand for precast concrete components is increasing. Precast concrete components need to be made using concrete molds. In the process of preparing precast concrete components, the concrete mold containing the concrete needs to be placed at a high temperature for steam curing, so that the concrete can be quickly formed.

[0003] Most existing production methods involve pouring the mixed concrete directly into concrete molds and then subjecting it to high-temperature steam curing. In cold winter months, the low temperature of the molds can slow down the steam curing process. Furthermore, the large temperature difference between the molds and the high-temperature steam can damage the molds, thus affecting the quality of the precast concrete components. Utility Model Content

[0004] This invention provides a temperature-adjustable concrete mold preheating device, which solves the technical problem of slow high-temperature steam curing speed and poor quality of concrete precast parts caused by excessively low concrete mold temperature in winter.

[0005] To achieve this technical objective, the present invention adopts the following solution: a temperature-adjustable concrete mold preheating device, comprising a fixing mechanism, an adjustable support mechanism, and a preheating mechanism;

[0006] The fixing mechanism is detachably mounted on the concrete mold and is used to fix the adjustable support mechanism to the concrete mold.

[0007] The adjustable support mechanism is slidably mounted on the fixed mechanism to support the preheating mechanism;

[0008] The preheating mechanism is detachably mounted on an adjustable support mechanism for preheating concrete molds.

[0009] Furthermore, the fixing mechanism includes a first fixing component and a second fixing component;

[0010] The first fixing component includes a crossbeam, with extension beams fixed at both ends of the crossbeam and distributed perpendicularly thereto. The extension beams have through slots and are threadedly connected to a first screw. One end of the first screw is rotatably connected to an anti-slip connecting plate, which abuts against the side wall of the concrete mold. The other end of the first screw is coaxially fixedly connected to a knob.

[0011] The second fixing component has the same structure as the first fixing component, and the second fixing component and the first fixing component are symmetrically distributed.

[0012] The second fixing component and the first fixing component are connected as one unit by a connecting beam.

[0013] Furthermore, the adjustable support mechanism includes a first support component and a second support component that are symmetrically distributed;

[0014] The first support component includes a slide groove, and a second screw extending laterally is fixed on the sides of the top and bottom of the slide groove. The second screw is slidably inserted into the through groove. A nut is connected to the first thread of the second screw away from the slide groove. An anti-slip pad is provided between the nut and the extension beam. One side of the anti-slip pad abuts against the nut, and the other side of the anti-slip pad abuts against the extension beam.

[0015] The second support component has the same structure as the first support component, and the groove opening of the slide of the first support component is opposite to the groove opening of the slide of the second support component.

[0016] Furthermore, the preheating mechanism includes a fixed frame and water pipes;

[0027] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0028] like Figures 1 to 4 As shown, the present invention provides an adjustable temperature concrete mold preheating device, comprising a fixing mechanism 1, an adjustable support mechanism 2, and a preheating mechanism 3. The fixing mechanism 1 is detachably mounted on the concrete mold 4 and is used to fix the adjustable support mechanism 2 on the concrete mold 4.

[0029] The fixing mechanism 1 includes a first fixing component 11 and a second fixing component 12. The first fixing component 11 includes a crossbeam 111, with extension beams 112 perpendicularly distributed at both ends. The extension beams 112 have through slots 113 and are threadedly connected to a first screw 114. One end of the first screw 114 is rotatably connected to an anti-slip connecting plate 115, which abuts against the side wall of the concrete mold 4. The other end of the first screw 114 is coaxially fixedly connected to a knob 116. The second fixing component 12 has the same structure as the first fixing component 11, and the second fixing component 12 and the first fixing component 11 are symmetrically distributed. Figure 1 For example, the second fixing component 12 is located below the first fixing component 11. The second fixing component 12 and the first fixing component 11 are connected as one unit by a connecting beam 13.

[0030] An adjustable support mechanism 2 is slidably mounted on a fixed mechanism 1 to support a preheating mechanism 3. The adjustable support mechanism 2 includes a first support assembly 21 and a second support assembly 22 symmetrically distributed. The first support assembly 21 includes a groove 211, with laterally extending second screws 212 fixed to the top and bottom sides of the groove 211. The second screws 212 are slidably inserted into a through groove 113. A nut 213 is threadedly connected to the second screw 212 away from the groove 211. An anti-slip pad 214 is provided between the nut 213 and the extension beam 112. After the nut 213 is tightened, one side of the anti-slip pad 214 abuts against the nut 213, and the other side of the anti-slip pad 214 abuts against the extension beam 112. The second support assembly 22 has the same structure as the first support assembly 21, with the groove opening of the first support assembly 21 opposite to the groove opening of the second support assembly 22.

[0031] The preheating mechanism 3 is detachably mounted on the adjustable support mechanism 2 and is used to preheat the concrete mold 4. The preheating mechanism 3 includes a fixed frame 31 and a water pipe 32. Both ends of the fixed frame 31 are slidably inserted into the slide groove 211, and the tops of both ends of the fixed frame 31 extend out from the inside of the slide groove 211. An extension rod 311 is fixed to the side of the top of the fixed frame 31, which makes it easier to move the fixed frame 31. The water pipe 32 is mounted on the fixed frame 31 in a serpentine fixed disc.

[0032] In use, first move the fixing mechanism 1 to the vicinity of the concrete mold 4, then lift the fixing mechanism 1 and turn the knob 116. The knob 116 drives the first screw 114 to rotate, and the first screw 114 drives the anti-slip connecting plate 115 to approach the side wall of the concrete mold 4 until the anti-slip connecting plate 115 abuts against the side wall of the concrete mold 4. Through the friction between the anti-slip connecting plate 115 and the concrete mold 4, the fixing mechanism 1 is fixed to the concrete mold 4. Then, insert the second screw 212 into the through groove 113, and install the anti-slip pad 214 and nut 213 onto the second screw 212 respectively. At this time, the nut 213 is left loose. Next, insert both ends of the fixing frame 31 with the water pipe 32 into the slide groove 211, adjust the position of the second screw 212 in the through groove 113, and then adjust the distance between the water pipe 32 and the concrete mold 4. After adjustment, tighten nut 213 to fix the position of slide 211 and further determine the position of water pipe 32. Then, hot water is introduced into water pipe 32 to preheat concrete mold 4.

[0033] Obviously, the preheating temperature of the concrete mold 4 can be adjusted by controlling the temperature of the water in the water pipe 32 and the distance between the water pipe 32 and the concrete mold 4.

[0034] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
