[0017] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0018] Embodiment 1

[0019] This embodiment provides a technical solution: a concrete pouring template, such as Figure 1 As shown, it includes four groups of angle steel panels 1, which are connected in sequence to form a pouring cavity 2. When pouring concrete, the four groups of angle steel panels 1 are connected in sequence as shown in FIG. Figure 1 The state shown is placed in the construction position, so the casting cavity 2 formed in the middle of the four groups of angle steel enclosures 1 can be used for concrete casting and forming. The angle steel enclosure 1 includes an angle steel plate 101, two mold frames 102 and two rubber bladders 103. The two mold frames 102 are respectively arranged at both ends of the angle steel plate 101, and a receiving groove 3 is opened at the front edge of the mold frame 102 and the connection with the end of the angle steel plate 101. The rubber bladder 103 is arranged in the receiving groove 3 and the two sides are respectively bonded to the mold frame 102 and the angle steel plate 101. The mold frame 102 and the angle steel plate 101 are softly connected through the rubber bladder 103. During the casting process, the edge of the angle steel plate 101 contacts the edge of the mold frame 102, so the stability is sufficient. A water storage cavity is arranged in the rubber bladder 103, and a U-shaped guide pipe 4 is installed on the outside of the angle steel plate 101 and the mold frame 102. The U-shaped guide pipe 4 is connected to the rubber bladder 103. The water storage chamber is connected to the U-shaped guide tube 4, and the water storage chamber and the U-shaped guide tube 4 are filled with clean water. The clean water can be used to regulate the environment of the angle steel plate 101 and the concrete, and the water storage capacity can be increased by the hollow characteristic of the rubber bladder 103. A water pump 5 is installed at the bottom of the front side of the angle steel plate 101. The water pump 5 is connected to the two ends of the U-shaped guide tube 4 through pipelines. The water pump 5 can drive the clean water in the water storage chamber and the U-shaped guide tube 4 to circulate. A control valve 6 is installed on the U-shaped guide tube 4 located at the top of the angle steel plate 101 and connected to the rubber bladder 103. The control valve 6 can block the water flow, so that the water in the U-shaped guide tube 4 outside the angle steel plate 101 can be pumped into the U-shaped guide tube 4 outside the mold frame 102 and the rubber bladder 103, so that the rubber bladder 103 can be expanded and deformed, thereby achieving the effect of automatic demoulding.

[0020] Further, such as Figure 2-Figure 4As shown, a connecting plate 7 is installed on one side of the mold frame 102, and connecting grooves 8 are opened at both ends of the angle steel plate 101. The connecting plate 7 is clamped in the connecting groove 8. The cooperation between the connecting plate 7 and the connecting groove 8 can ensure that the connecting plate 7 can automatically move along the connecting groove 8 when the rubber bladder 103 expands and deforms.

[0021] Furthermore, an expansion groove 9 is opened on the inner wall of the connecting groove 8, and a limiting protrusion 10 is extended from the edge of the connecting plate 7. The limiting protrusion is stuck in the expansion groove 9. The limiting protrusion 10 can prevent the mold frame 102 and the angle steel plate 101 from separating, thereby ensuring the structural stability of the angle steel enclosure 1.

[0022] Furthermore, the U-shaped guide tube 4 located at the edge of the angle steel plate 101 and the edge of the mold frame 102 are extended with an extension tube 15, and the extension tube 15 is clamped in the water storage cavity. The extension tube 15 can ensure that the connection between the U-shaped guide tube 4 and the rubber bladder 103 is well sealed, and the clean water inside will not flow out when the rubber bladder 103 is deformed.

[0023] Furthermore, a docking plate 16 is installed on the edge of the other side of the mold frame 102, and a docking hole 17 is opened on the docking plate 16. The docking plate 16 can facilitate the fixed connection between adjacent angle steel enclosures 1, and the two contacting docking plates 16 can be fixedly connected by using bolts and nuts, thereby ensuring the stability of the four-sided structure during the pouring operation.

[0024] In this embodiment, four sets of angle iron panels are arranged as follows: Figure 1 The state shown is placed in the pouring construction area, and the two contact-connected butt plates 16 can be fixedly connected by using bolts and nuts, so that the four-sided structure can be stable during the pouring operation, and then the pouring operation can be carried out inward. After the concrete is poured into the pouring cavity 2, it can be formed after drying. At this time, the concrete state is as follows Figure 5 As shown, the concrete contacts the inner wall of the angle iron enclosure. After forming, the control valves 6 on both sides of the mirrored arrangement are closed in pairs, and the water pump 5 on this side is started at the same time, so that the water pump 5 can pump the water in the U-shaped guide pipe 4 outside the angle steel plate 101 into the U-shaped guide pipe 4 outside the mold frame 102 and the rubber bladder 103, and then the rubber bladder 103 can expand and deform, so the rubber bladder 103 can push the angle steel plate 101 and the mold frame 102 for a distance, and at the same time the connecting plate 7 can adaptively move along the connecting groove 8, at this time, the demoulding between the concrete inside the area and the angle steel enclosure 1 is completed, and the above operation can be performed four times to demould the four sides, and the internal state is as follows Figure 6As shown, the concrete is demoulded. It should be noted that in order to ensure that the expansion direction of the rubber bladder 103 and the movement direction of the connecting plate 7 are correct, the wall thickness of the water storage chamber close to the accommodating groove 3 can be controlled to be thinner, and the wall thickness not in contact with the accommodating groove 3 can be increased, or a limiting structure can be added externally to control the expansion direction of the rubber bladder 103.

[0025] Embodiment 2

[0026] This embodiment provides a technical solution: a concrete pouring template, such as Figure 1 As shown, it includes four groups of angle steel panels 1, which are connected in sequence to form a pouring cavity 2. When pouring concrete, the four groups of angle steel panels 1 are connected in sequence as shown in FIG. Figure 1 The state shown is placed in the construction position, so the casting cavity 2 formed in the middle of the four groups of angle steel enclosures 1 can be used for concrete casting and forming. The angle steel enclosure 1 includes an angle steel plate 101, two mold frames 102 and two rubber bladders 103. The two mold frames 102 are respectively arranged at both ends of the angle steel plate 101, and a receiving groove 3 is opened at the front edge of the mold frame 102 and the connection with the end of the angle steel plate 101. The rubber bladder 103 is arranged in the receiving groove 3 and the two sides are respectively bonded to the mold frame 102 and the angle steel plate 101. The mold frame 102 and the angle steel plate 101 are softly connected through the rubber bladder 103. During the casting process, the edge of the angle steel plate 101 contacts the edge of the mold frame 102, so the stability is sufficient. A water storage cavity is arranged in the rubber bladder 103, and a U-shaped guide pipe 4 is installed on the outside of the angle steel plate 101 and the mold frame 102. The U-shaped guide pipe 4 is connected to the rubber bladder 103. The water storage chamber is connected to the U-shaped guide tube 4, and the water storage chamber and the U-shaped guide tube 4 are filled with clean water. The clean water can be used to regulate the environment of the angle steel plate 101 and the concrete, and the water storage capacity can be increased by the hollow characteristic of the rubber bladder 103. A water pump 5 is installed at the bottom of the front side of the angle steel plate 101. The water pump 5 is connected to the two ends of the U-shaped guide tube 4 through pipelines. The water pump 5 can drive the clean water in the water storage chamber and the U-shaped guide tube 4 to circulate. A control valve 6 is installed on the U-shaped guide tube 4 located at the top of the angle steel plate 101 and connected to the rubber bladder 103. The control valve 6 can block the water flow, so that the water in the U-shaped guide tube 4 outside the angle steel plate 101 can be pumped into the U-shaped guide tube 4 outside the mold frame 102 and the rubber bladder 103, so that the rubber bladder 103 can be expanded and deformed, thereby achieving the effect of automatic demoulding.

[0027] Further, such as Figure 2-Figure 4 As shown, a connecting plate 7 is installed on one side of the mold frame 102, and connecting grooves 8 are opened at both ends of the angle steel plate 101. The connecting plate 7 is clamped in the connecting groove 8. The cooperation between the connecting plate 7 and the connecting groove 8 can ensure that the connecting plate 7 can automatically move along the connecting groove 8 when the rubber bladder 103 expands and deforms.

[0028] Furthermore, an expansion groove 9 is opened on the inner wall of the connecting groove 8, and a limiting protrusion 10 is extended from the edge of the connecting plate 7. The limiting protrusion is stuck in the expansion groove 9. The limiting protrusion 10 can prevent the mold frame 102 and the angle steel plate 101 from separating, thereby ensuring the structural stability of the angle steel enclosure 1.

[0029] In a specific implementation, a water treatment box 11 is further provided at the bottom of the front side of the angle steel plate 101, and the water treatment box 11 is connected to the U-shaped guide pipe 4 and one end of the water pump 5. An installation folding plate 12 is installed on the outer side of the corner of the angle steel plate 101, and heating plates 13 are installed on both sides of the installation folding plate 12. The heating plate 13 is arranged on the outer side of the water treatment box 11. The water in the U-shaped guide pipe 4 and the water storage cavity can be heated by the heating plate 13 on the outer side of the water treatment box 11, thereby preventing freezing of the concrete inside in a low temperature environment. The heating plate 13 can continuously heat the water treatment box 11, thereby heating the clean water passing through the water treatment box 11, and then the warm water can be circulated under the drive of the water pump 5, so that the heat can be transferred through the angle steel enclosure 1 to increase the temperature of the internal concrete.

[0030] Furthermore, the U-shaped guide tube 4 located at the edge of the angle steel plate 101 and the edge of the mold frame 102 are extended with an extension tube 15, and the extension tube 15 is clamped in the water storage cavity. The extension tube 15 can ensure that the connection between the U-shaped guide tube 4 and the rubber bladder 103 is well sealed, and the clean water inside will not flow out when the rubber bladder 103 is deformed.

[0031] Furthermore, a docking plate 16 is installed on the edge of the other side of the mold frame 102, and a docking hole 17 is opened on the docking plate 16. The docking plate 16 can facilitate the fixed connection between adjacent angle steel enclosures 1, and the two contacting docking plates 16 can be fixedly connected by using bolts and nuts, thereby ensuring the stability of the four-sided structure during the pouring operation.

When pouring concrete, the four groups of angle steel panels 1 are connected in sequence as shown in FIG. Figure 1The state shown is placed in the construction position, so the casting cavity 2 formed in the middle of the four groups of angle steel enclosures 1 can be used for concrete casting and forming. The angle steel enclosure 1 includes an angle steel plate 101, two mold frames 102 and two rubber bladders 103. The two mold frames 102 are respectively arranged at both ends of the angle steel plate 101, and a receiving groove 3 is opened at the front edge of the mold frame 102 and the connection with the end of the angle steel plate 101. The rubber bladder 103 is arranged in the receiving groove 3 and the two sides are respectively bonded to the mold frame 102 and the angle steel plate 101. The mold frame 102 and the angle steel plate 101 are softly connected through the rubber bladder 103. During the casting process, the edge of the angle steel plate 101 contacts the edge of the mold frame 102, so the stability is sufficient. A water storage cavity is arranged in the rubber bladder 103, and a U-shaped guide pipe 4 is installed on the outside of the angle steel plate 101 and the mold frame 102. The U-shaped guide pipe 4 is connected to the rubber bladder 103. The water storage chamber is connected to the U-shaped guide tube 4, and the water storage chamber and the U-shaped guide tube 4 are filled with clean water. The clean water can be used to regulate the environment of the angle steel plate 101 and the concrete, and the water storage capacity can be increased by the hollow characteristic of the rubber bladder 103. A water pump 5 is installed at the bottom of the front side of the angle steel plate 101. The water pump 5 is connected to the two ends of the U-shaped guide tube 4 through pipelines. The water pump 5 can drive the clean water in the water storage chamber and the U-shaped guide tube 4 to circulate. A control valve 6 is installed on the U-shaped guide tube 4 located at the top of the angle steel plate 101 and connected to the rubber bladder 103. The control valve 6 can block the water flow, so that the water in the U-shaped guide tube 4 outside the angle steel plate 101 can be pumped into the U-shaped guide tube 4 outside the mold frame 102 and the rubber bladder 103, so that the rubber bladder 103 can be expanded and deformed, thereby achieving the effect of automatic demoulding.

[0035] Furthermore, an expansion groove 9 is opened on the inner wall of the connecting groove 8, and a limiting protrusion 10 is extended from the edge of the connecting plate 7. The limiting protrusion is stuck in the expansion groove 9.

The water treatment box 11 and the heat dissipation fin 14 at the bottom thereof can reduce the temperature of the concrete in a high temperature environment, thereby preventing the concrete surface from drying and cracking. The concrete can transfer the temperature to the angle steel enclosure 1 through heat conduction. The water in the U-shaped guide pipe 4 and the water storage cavity can help the angle steel enclosure 1 to dissipate heat, thereby achieving a cooling effect.
