[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1-Figure 2 As shown, the present invention is an integrated edge protection shaping device for prefabricated beams of prefabricated buildings, comprising four groups of keel square steels 2, which are arranged relatively on a channel steel base 101. In one implementation of this embodiment, the four groups of keel square steels 2 are integrated with the channel steel base 101 to form a protective shaping bracket;

[0041] The protective shaping bracket is detachably arranged on the prefabricated beam body 1 via the channel steel base 101; specifically, by arranging the detachable protective shaping bracket on the prefabricated beam body 1, the connection between the protective shaping bracket and the prefabricated beam body 1 is simplified and easy to assemble and disassemble;

[0042] Among them, a protective mesh 3 is arranged between two adjacent groups of keel square steels 2, and positioning seats 301 are arranged at both ends of the protective mesh 3. The positioning seats 301 are provided with U-shaped grooves 302 for sliding relative to the side edges of the keel square steels 2; it can be explained that after the keel square steels 2 are fixed to the channel steel base 101 by welding, the U-shaped grooves 302 at both ends of each group of protective mesh 3 are respectively slidably connected to the side edges of adjacent keel square steels 2. As another embodiment, when the protective mesh 3 slides on the keel square steel 2, in order to adjust the height of the protective mesh 3, several groups of positioning holes are opened on the positioning seats 301, and positioning pins are spirally arranged in the positioning holes. When the height of the protective mesh 3 is adjusted, the positioning pins are rotated so that the positioning pins abut against the keel square steel 2. The protective mesh 3 is positioned based on the friction between the positioning pins and the keel square steel 2, thereby determining the position of the protective mesh 3.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 3 , a plurality of sets of screw rods 4 are pre-embedded and arranged on the prefabricated beam body 1, wherein screw holes corresponding to the screw rods 4 are opened on the channel steel base 101, and the channel steel base 101 is fixedly arranged on the screw rods 4 of the prefabricated beam body 1 via nuts 401; it should be noted that, by pre-embedded screw rods 4 on the prefabricated beam body 1, when installing the protective shaping bracket, the screw rods 4 are correspondingly inserted into the screw holes on the channel steel base 101, and then the nuts 401 are screwed on the screw rods 4 to fix the channel steel base 101 on the prefabricated beam body 1;

[0045] In one implementation of this embodiment, four sets of screws 4 are pre-embedded on the precast beam body 1, wherein the screws 4 are respectively arranged on one side close to the keel square steel 2, and four sets of screw holes are correspondingly opened on the channel steel base 101;

[0046] As a further solution of this embodiment, a reinforcing plate 5 is arranged between the keel square steel 2 and the screw 4. One end of the reinforcing plate 5 is connected to the keel square steel 2 through a first connecting mechanism, and the other end is connected to the screw 4 through a second connecting mechanism. It can be explained that after the channel steel base 101 is installed on the prefabricated beam body 1, the reinforcing plate 5 is installed between the keel square steel 2 and the screw 4 through the first connecting mechanism and the second connecting mechanism respectively. On the one hand, the strength of the protective shaping bracket can be improved, and on the other hand, the nut 401 can be limited to prevent the nut 401 from slipping off the screw 4 when bearing a large weight.

[0047] See also Figure 4-Figure 5, the first connecting mechanism includes a card plate 202 arranged at the end of the reinforcing plate 5, a first slide groove 201 for embedding the card plate 202 is correspondingly opened on the keel square steel 2, and a card hole is opened at the end of the card plate 202, wherein a support 203 is arranged on the keel square steel 2, and a second slide groove 204 is opened on the support 203, and a card rod 205 for plugging into the card hole is slidably arranged in the second slide groove 204; it can be explained that when fixing the reinforcing plate 5, the card plate 202 on the end of the reinforcing plate 5 is embedded in the first slide groove 201 and extended a certain distance, and then the card rod 205 is inserted into the card hole to achieve the fixation of the card plate 202;

[0048] As a further solution of this embodiment, the side of the card rod 205 away from the card plate 202 is fixedly connected to the first positioning rod 206, the diameter of the first positioning rod 206 is larger than the groove width of the second slide groove 204, and a first return spring 208 is arranged on the first positioning rod 206; it can be explained that one end of the first return spring 208 is connected to the support 203, and the other end is connected to the first handle 207 arranged at the end of the first positioning rod 206; specifically, before the card rod 205 is plugged into the card hole, the first handle 207 is first pulled to move in the direction away from the support 203, and the first return spring 208 is stretched to generate an elastic force. When the position of the card hole and the card rod 205 is adapted, the first handle 207 is released, and the first return spring 208 drives the first positioning rod 206 to move toward the support 203 under the action of the elastic force, so that the card rod 205 is plugged into the card hole. Since the diameter of the first positioning rod 206 is larger than the groove width of the second slide groove 204, the first positioning rod 206 is limited.

[0049] See also Figure 6 The second connecting mechanism includes a limiting hole 501 opened at the end of the screw 4, wherein the end of the reinforcing plate 5 is provided with a limiting seat 402, the limiting seat 402 is provided with a groove 407 for sleeved on the screw 4, and a corresponding insertion hole 406 is opened on the groove wall of the groove 407. A second positioning rod 404 can be slidably arranged in the insertion hole 406, and a second return spring 403 is arranged on the second positioning rod 404; specifically, a second handle 405 is provided at the end of the second positioning rod 404, and one end of the second return spring 403 is connected to the limiting The seat 402 is fixedly connected, and the other end is fixedly connected to the second handle 405. It can be explained that when installing the reinforcing plate 5, the second handle 405 is first pulled in the direction away from the limiting seat 402, and the second handle 405 synchronously drives the second positioning rod 404 to slide, so as to achieve the extension of the second return spring 403. After the limiting seat 402 is sleeved on the screw rod 4, the second handle 405 is released, so that the second return spring 403 drives the second positioning rod 404 to pass through the insertion hole 406 and plug into the limiting hole 501;

[0050] In this embodiment, the reinforcing plate 5 is installed through a detachable first connecting mechanism and a second connecting mechanism, which is very convenient for assembly and disassembly and has a wider range of applications.
