[0026] Embodiment 1:

[0027] Please refer to Figure 1-6 , a guardrail for housing construction, wherein a plurality of fixing rods 2 in a linear array are fixedly installed in the guardrail body 1, and a warning sign 3 is arranged on the outer surface of the fixing rod 2, and adjustment holes 4 are opened on the end faces of both sides of the guardrail body 1, and connecting holes 5 are opened in the fixing rod 2, and four limiting holes 6 in a linear array are opened on the front end surface of the guardrail body 1, and a connecting frame 7 is movably inserted at the top of the guardrail body 1, and a plurality of connecting rods 8 in a linear array are fixedly installed at the bottom of the connecting frame 7, and the connecting rods 8 are all inserted in the connecting holes 5, and springs 9 are fixedly installed inside the connection, and a limiting block 10 is fixedly installed on the front end surface of the spring 9, and the diameter of the limiting hole 6 is smaller than that of the limiting hole 6, and two plugging rods 11 are fixedly installed on the left end face of the guardrail body 1, and two slots 12 are opened on the right end face of the guardrail body 1, and the diameter of the slot 12 is larger than that of the plugging rod 11.

[0028] Working principle: When the guardrail body 1 needs to be extended, the two side rods 11 installed on the left end face of the guardrail can be inserted into the slot 12. Then, because the diameter of the slot 12 is larger than the rod 11, the rod 11 can be better inserted into the slot 12, so as to facilitate the extension of the guardrail body 1, and also make it easier for workers to assemble and disassemble it. Then, the warning sign 3 set on the surface of the fixed rod 2 can warn passers-by. Then, because the connecting frame 7 and the connecting rod 8 are both inserted in the connecting hole 5 and the limiting hole 6, their height can be adjusted. Then, when the height of the guardrail body 1 needs to be adjusted, by pressing the limiting block 10 inward, the limiting block 10 can be adjusted. The limit block 10 is connected to the spring 9, so when the limit block 10 is pressed, the spring 9 will drive the limit block 10 to retract toward the inside of the connecting frame 7, which is also convenient for disassembly of the guardrail main body 1. Then, when the connecting frame 7 is no longer restricted, the height of the guardrail main body 1 is adjusted by pulling the connecting frame 7 upward. Then, when the height of the guardrail main body 1 is adjusted to a suitable position, the limit block 10 will be unrestricted, and the limit block 10 will extend from the limit hole 6 opened on the front end surface of the guardrail main body 1 to limit the connecting frame 7. Then, because the connecting rods 8 in the connecting frame 7 are inserted in the connecting holes 5, the extended connecting frame 7 can be kept stable.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-6 A guardrail for house construction, wherein adjustment plates 13 are fixedly installed on both sides of the rear end surface of the guardrail body 1, and an adjustment block 14 is arranged on the adjustment plate 13.

A connecting shaft 16 is fixedly installed on the outer surface of the adjustment block 14, and a connecting plate 17 is arranged inside the connecting shaft 16. A connecting block 18 is arranged at the bottom of the connecting plate 17, and a supporting foot 19 is fixedly installed at the bottom of the connecting block 18. Four through holes 20 are opened on the surface of the supporting foot 19, and the four through holes 20 are arranged in a rectangular array on the surface of the supporting foot 19.

[0031] Working principle: By moving the adjusting block 14 up and down, the adjusting block 14 drives the height between the supporting foot 19 and the ground to be adjusted, so as to adapt to some uneven ground. Then, after the adjusting block 14 is adjusted from the position on the adjusting plate 13, the two positioning bolts 15 on the adjusting block 14 are rotated so that the positioning bolts 15 are in contact with the adjusting plate 13, so that the adjusting block 14 is fixed, and then the supporting foot 19 is adjusted. Since the supporting foot 19 is connected to the connecting plate 17 through the connecting block 18, the supporting foot 19 can be adjusted. Since there are four through holes 20 on the supporting foot 19, the positioning bolts 15 are inserted into the through holes 20 on the supporting foot 19 after the supporting foot 19 is adjusted, so that the guardrail body 1 is stably fixed.
