In actual use, the number of cross bars 103 and vertical bars 102 can be increased as required, so as to meet the needs of balconies of different shapes and sizes. When the shape of the balcony is relatively complex, the short size cross bar 103 and the vertical bar 102 can be used to form a guardrail, and then the multi-section combination method can be used to set along the balcony structural plate 101, so as to enclose the balcony. [0043] embodiment 2 [0044] refer to figures 2 to 7. This embodiment provides a balcony guardrail, which is used for the balcony part in the construction processThe enclosure of the position. The balcony guardrail includes two cross bars 103 and three vertical bars 102. One end of the vertical bar 102 is fixedly provided with a clamp 104 for clamping the balcony structural plate 101. The vertical bar is detachably connected to the balcony structural plate 101 through the clamp 104, and the cross bar 103 is detachably connected with the side wall of the vertical bar 102. [0045] the clamp 104 includes a U-shaped clamp 201, a first fastening bolt 203 and a first nut 202 matching the first fastening bolt 203. One end of the U-card 201 is fixedly arranged on the upright rod 102, and the first nut 202 is fixedly arranged on the other end of the U-card 201, see Fig. 5. A first through hole 204 is arranged at the corresponding place of the U-shaped card 201 and the first nut 202, and the first through hole 204 is coaxially communicated with the threaded hole of the first nut 202. The first fastening bolt 203 passes through the first through hole 204, and the first nut 202 is in contact with the balcony structural plate 101. The U-shaped groove of the U-shaped card 201 is used to place the edge of the balcony structural plate 101. The first fastening bolt 203 passes through the first through hole 204, and then the first fastening bolt 203 is screwed through the first nut 202, and then contacts with the balcony structural plate 101. Continue to twist the first fastening bolt 203, so that it is tightly against the balcony structural plate 101, see Fig. 3. As another implementation method, one end of the U-card 201 is fixedly connected to the end of the vertical rod 102, and the other end is a free end. The U-card 201 and the vertical rod 102 can be fixed by welding and threaded connection. Due to U-card 2One end of 01 is fixedly connected to the end of the upright 102, so the inner wall of the U-shaped groove can completely contact with the balcony structural plate 101, so that the connection between the U-shaped card 201 and the balcony structural plate 101 is more compact and firm, see Fig. 6. Preferably, the bottom of the U-shaped groove of the U-shaped card 201 is provided with a limited position groove, the thickness of which is the same as that of the balcony structural plate 101, so that when the U-shaped card 201 is connected with the balcony structural plate 101, the balcony structural plate 101 can extend into the limited position groove and play the role of restricting the movement of the U-shaped card 201. [0046] in order to improve the connection firmness of the first fastening bolt 203, the first through hole 204 is provided with a first through hole thread, and the first through hole is matched with the first fastening bolt 203 through the first through hole thread. In this way, the first through-hole 204 and the first nut 202 are all connected with the first fastening bolt 203 by threads. When the threads on the nut are damaged by external forces, the threads in the first through-hole 204 can be used as an auxiliary to limit the first fastening bolt 203 to prevent its displacement, so as to maintain the connection stability between the first fastening bolt 203 and the balcony structural plate 101, thus ensuring the vertical rod 102 and the horizontal rod The stability of rod 103. On the other hand, by fixing the first fastening bolt 203 in two positions through the first through hole 204 and the first nut 202, the first fastening bolt 203 can play a role of protection against the impact from the side. [0047] since the balcony guardrail needs to bear considerable pressure, the fixture 104 uses the first fastening bolt 203 toThe first fastening bolt 203 may damage the balcony structural plate 101 when the balcony guardrail is subjected to a large external force. In view of the above problems, the balcony guardrail also includes a first gasket 206. The first gasket 206 is used to reduce the pressure of the first fastening bolt 203 on the balcony structural plate 101, so as to avoid the damage of the balcony structural plate 101. The surface area of the first gasket 206 is larger than the sectional area of the vertical rod 102, and the first gasket 206 and the vertical rod 102 form a T-shaped structure. The first gasket 206 is fixedly arranged at the end of the vertical rod 102, and the first gasket 206 fits the balcony structural plate 101, see Fig. 4. The first gasket 206 is the buffer structure between the first fastening bolt 203 and the balcony structural plate 101. Because the first gasket 206 has a large surface area, the force of the upright 102 on the balcony structural plate 101 is dispersed by the first gasket 206, so that the pressure on the balcony structural plate 101 is reduced, so that the upright 102 can avoid damaging the balcony structural plate 101 due to the large pressure, so that the balcony structural plate 101 can be avoided The connection firmness and safety of guardrail can be improved. In addition, the contact area between the first gasket 206 and the balcony structural plate 101 is larger, so that the first gasket 206 can be more firmly attached to the balcony structural plate 101. When the balcony guardrail is impacted by the outside, the first gasket 206 maintains the stability of the vertical rod 102. The first gasket can also be provided with a limit slot. When the first fastening bolt 203 extends into the limit slot, the limit slot will limit its movement position, and the first fastening bolt can rotateMove, but there is no offset with the first gasket 206, so as to ensure the firmness of the connection between the U-shaped card and the balcony structural plate 101, see Fig. 5. [0048] preferably, the first gasket 206 is provided with a convex pattern on the contact side of the balcony structural plate 101, the convex pattern includes a longitudinal pattern and a transverse pattern, and the intersection of the longitudinal pattern and the transverse pattern forms a grid. The convex pattern improves the friction between the first gasket 206 and the balcony structural plate 101, making it difficult for the first gasket 206 to slide. Because of the structure of the longitudinal and transverse striations of the convex striations , the first gasket 206 can provide relatively stable friction force at multiple angles. When the balcony guardrail is subject to different directions of force, the first gasket 206 can maintain a fixed position relative to the balcony structural plate 101, so as to prevent the inclination of the upright 102 and other situations. Further, the balcony guardrail further comprises a second gasket 205 fixed at the end of the first fastening bolt 203, and the second gasket 205 is in contact with the balcony structural plate 101. When the first fastening screw is twisted, the moving first fastening screw continuously pushes the second gasket 205, and then makes the second gasket 205 and the balcony structural plate101 contact, continue to twist the first fastening screw to make the second gasket 205 tightly against the balcony structural plate 101. The combination of the first gasket 206, the second gasket 205 and the U-shaped card 201 improves the connection firmness and stability between the balcony guardrail and the balcony structural plate 101, and can play a protective role for the balcony structural plate 101.
