It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations.

[0003] Guardrails are usually required for protection during construction. The height of existing guardrails is mostly non-adjustable, so the height of the guardrail protection is also fixed. It is difficult to provide adaptive protection for obstacles of different heights generated during the construction process, which has certain limitations.

[0004] Therefore, it is necessary to provide a kind of guardrail for building construction to solve the above problems. Utility Model Content

[0008] Preferably, the telescopic rod comprises a sleeve and an inner rod, and the sleeve is slidably sleeved on the inner rod.

[0009] Preferably, the spray assembly includes a water outlet pipe, a nozzle, a pulley, a belt and a driving motor. The water outlet pipe is connected to the top of the top plate through a sealed bearing. The water outlet pipes are arranged in multiple numbers and are evenly distributed. Pullies are fixedly sleeved on the outside of several water outlet pipes, and adjacent pulleys are connected by belt transmission. Spray heads are connected to the tops of several water outlet pipes, and the driving motor is drivingly connected to a water outlet pipe.

[0010] Preferably, a protection box is provided on the top of the top plate and outside the water outlet pipe, and the water outlet pipe is rotatably connected to the protection box.

[0011] Preferably, the driving motor is installed at the top of the protection box, the output shaft of the driving motor is connected to a driving gear, a driven gear is fixedly sleeved on the outer wall of the water outlet pipe, and the driven gear is meshingly connected to the driving gear.

[0012] Preferably, the column has a rectangular cross-section, and the collar is adapted to the column.

[0013] The beneficial effects of the utility model are as follows: the base can be installed in a suitable position by passing an external bolt through the installation hole through the installation hole through the installation hole. When the height of the guardrail protection needs to be adjusted, the top plate is moved up and down to drive the telescopic rod to extend and retract, so that the top plate is moved to a suitable height, and the limiting bolts of the rings on both sides are rotated to be inserted into the relatively aligned limiting holes, thereby completing the limiting and fixing process of the top plate, so as to adapt to protection work at different heights.
