[0001] The utility model relates to a road surface laying fixing device and belongs to the road construction field. BACKGROUND

[0002] In the cement road laying operation, the steel cross beam is an indispensable construction component of the roadbed edge. When pouring concrete, the steel cross beam can limit the spreading range of the concrete, and ensure the smooth pouring operation. At present, the steel cross beam is fixed through the cooperation of the positioning sleeve and the inserting rod, and the positioning sleeve is rotationally connected to the steel cross beam through the anchoring frame. However, the anchoring frame structure is relatively fixed, and the movement range of the positioning sleeve is limited. When there are obstacles in the construction site, the inserting rod cannot be inserted into the positioning sleeve, and the inserting rod cannot be smoothly inserted into the ground due to the limitation of the position of the steel cross beam, which undoubtedly increases the construction difficulty, prolongs the operation time, and affects the overall construction efficiency.

[0007] Further, a plurality of limiting holes matched with the round holes are equidistantly arranged on the upper surface of the rectangular rod, and the clamping bolts extend into the limiting holes.

[0008] Further, two first insertion pipes for inserting the insertion rod are symmetrically arranged and fixed at one side edge of the steel beam, and two second insertion pipes concentrically arranged with the first insertion pipes are installed at the side of the steel beam away from the first insertion pipes.

[0009] Further, a first round steel is fixed at one side of the steel beam, and a second round steel is installed at the side of the steel beam away from the first round steel.
