Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to an assembled highway toll station concrete panel. Background Art

[0002] During highway construction, toll booths are often built at the entrances. Cement concrete pavements are often used for highway toll booths due to their high stiffness, strong load-spreading capacity, strong resistance to bending, tension, and wear, and excellent stability. However, vehicle braking and starting can impose dynamic loads on cement concrete pavements, potentially damaging them. Repairs to these damaged surfaces can hinder traffic flow. To minimize the impact of repairs on traffic, it's crucial to find ways to shorten repair times. Utility Model Content

[0003] The utility model aims to provide an assembled highway toll station concrete panel that can shorten the maintenance time of the highway toll station ground, solving the problem that when the existing highway road surface is damaged, the road surface needs to be chiseled off and cement concrete needs to be re-poured, resulting in a long maintenance time and hindering traffic travel.

[0004] To achieve the above objectives, the present invention utilizes the following technology: an assembled highway toll station concrete panel, characterized by comprising a cast-in-place leveling layer and a precast layer consisting of precast concrete panels assembled on the cast-in-place leveling layer. The cast-in-place leveling layer is pre-embedded with connecting rods, the upper ends of which are detachably connected to the precast concrete panels. The connecting rods are made of steel, and the precast concrete panels are secured to the cast-in-place leveling layer solely by the connecting rods. This technical solution allows the highway toll station concrete panel to be easily repaired by simply removing the precast concrete panels if they become damaged, facilitating maintenance.

[0005] Preferably, the precast concrete slab is provided with a connecting hole, the upper end of which is provided with a large-diameter section, forming a step between the large-diameter end and the connecting hole. The connecting rods are respectively inserted into the connecting holes, and the upper end of the connecting rods is provided with a threaded section, on which a locking nut is threadedly connected. The locking nut is located within the large-diameter section and presses against the step to secure the precast concrete slab to the cast-in-place leveling layer. During use, a locking nut machine secures the precast concrete slab to the cast-in-place leveling layer. By removing the locking nut, the precast concrete slab can be lifted and removed, making replacement convenient.

[0006] Preferably, a plug is removably connected to the upper end of the connecting through hole to protect the locking nut and prevent the locking nut from being damaged over time, which makes it difficult to remove.

[0007] Preferably, the precast concrete panel is rectangular, and triangular metal corner guards are cast on the four corners of the precast concrete panel to protect the corners of the precast concrete panel and prevent the precast concrete panel from being damaged and becoming incomplete and unusable.

[0008] Preferably, the metal protective corner is provided with connecting feet cast in the concrete precast slab, which can improve the connection reliability between the metal protective corner and the concrete precast slab.

[0009] Preferably, the connecting legs extend along the diagonal direction of the precast concrete slab, so that the metal protective corner is not easily dislodged when subjected to a force along the edge direction of the precast concrete slab.

[0010] Preferably, one corner of each of the four precast concrete panels is aligned together, and a hook hole is provided on the upper surface of the metal corner guard. The hook hole is an elongated hole, and the angle between the hook hole and two adjacent sides of the precast concrete panel is an acute angle. The adjacent metal corner guards of two adjacent precast concrete panels are connected together by a limit rod with both ends inserted into the hook hole. This allows the precast concrete panels to interact as a whole after being laid, thereby being securely fixed together and not easily moving.

[0011] Preferably, the limiting rod is provided with a hook head, the limiting rod is inserted into the hook hole through the hook head, and the hook head abuts against the end wall of the hook hole, so that the connection and positioning effect is more reliable and accurate.

[0012] Preferably, the hooking hole is perpendicular to the diagonal line of the precast concrete panel.

[0013] Preferably, a widened portion is provided in the middle of the hook hole, and concrete is poured into the hook hole to prevent the limiting rod from falling off.

[0014] Beneficial effect: When damaged, the surface layer can be replaced quickly and easily without the need to destroy the old one and then re-pour it, which shortens the maintenance time and reduces the impact on vehicle traffic. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1 to 5 A prefabricated concrete panel for a highway toll station includes a cast-in-place leveling layer 1 and a prefabricated layer consisting of a concrete precast panel 2 assembled on the cast-in-place leveling layer. The cast-in-place leveling layer is pre-buried with a connecting rod 3 whose upper end is detachably connected to the concrete precast panel layer. The connecting rod is a metal structure. The concrete precast panel is fixed to the cast-in-place leveling layer only by the connecting rod. A connecting through-hole 4 is provided on the concrete precast panel, and a large-diameter section 5 is provided at the upper end of the connecting through-hole. A step 6 is formed between the large-diameter end and the connecting through-hole. The connecting rods are passed through the connecting through-holes in a one-to-one correspondence. A threaded section is provided at the upper end of the connecting rod, and a locking nut 7 is threadedly connected to the threaded section. The locking nut is located in the large-diameter section. The locking nut is pressed on the step to fix the concrete precast panel to the cast-in-place leveling layer.
