Description

Steel construction combination beam type temporary pavement

Technical Field

The utility model belongs to the technical field of the road construction, concretely relates to interim pavement of steel construction combination beam type.

Background

The main line of the municipal pipe network is generally laid along the road direction. As shown in fig. 1, when a pipe network is constructed on one side of an existing road 1, a construction area 2 is generally required to be enclosed, and a temporary access 3 is widened on the other side of the road to meet the requirement of bidirectional traffic of the road. Temporary sidewalks sometimes occupy and damage roadside green belts, and greening needs to be restored after construction is completed. At present, after earth surface greening materials are removed, steel plates are directly paved on the ground, but the steel plates are easy to bounce in the driving process of a vehicle, so that the driving safety is influenced; the other mode is that the temporary sidewalk is designed into a water stabilization layer and concrete pavement layer structure, after construction is completed, when restoration is carried out, concrete needs to be broken and transported to a specified waste site, the concrete pouring and removing construction period of the temporary sidewalk is long, and a large amount of materials are wasted.

Disclosure of Invention

The utility model aims at the above-mentioned problem, a steel construction combination beam formula temporary pavement is provided, the driving safety is guaranteed to it is extravagant to reduce the material.

The technical scheme of the utility model as follows:

the utility model provides a temporary pavement of steel construction combination beam type which characterized in that: comprises a plurality of sleeper beams and a plurality of beam plates; the sleeper beam is a concrete prefabricated member, at least 4 anchor bolts are arranged on each sleeper beam, the lower half part of each anchor bolt is embedded in the sleeper beam concrete, and the upper half part of each anchor bolt protrudes out of the top surface of the sleeper beam; each beam plate comprises a steel panel, a plurality of longitudinal back ridges are welded on the bottom surface of the panel along the longitudinal direction of the panel, a plurality of connecting rods are welded between every two adjacent longitudinal back ridges, a transverse back ridge is welded on each of the two ends of the bottom surface of the panel along the transverse direction of the panel, at least two anchoring plates parallel to the panel are welded on the outer side of each transverse back ridge, and screw holes are preset in the anchoring plates; a plurality of sleeper beams are transversely laid along the sidewalk, and a certain distance is reserved between every two adjacent sleeper beams; the multiple beam plates are laid in sequence along the vertical direction of the sidewalk, two ends of each beam plate are supported on two adjacent sleepers respectively, opposite ends of the two adjacent beam plates are supported on the same sleeper and have a certain distance, each anchoring plate at two ends of each beam plate is arranged on the anchoring bolt on the top surface of the sleeper in a penetrating mode respectively, and the anchoring plates are tightly pressed on the top surface of the sleeper by the aid of the bolt nuts on the anchoring bolts.

The utility model adopts the principle of a simply supported beam structure, combines the steel structure beam plate with the sleeper beam to form the simply supported beam structure, combines the ground support, and the longer the rolling time is, the more closely the steel beam is combined with the ground, the more stable the structure is, and the better the safety is; concrete does not need to be poured to harden the road surface, after construction of one road section is completed, the beam plates and the sleeper beams are moved to the next road section to be continuously used, greening can be directly restored on the original ground, material waste is avoided, and construction progress blocks are formed.

Detailed Description

As shown in fig. 2 and 3, the present invention includes a plurality of sleepers 4 and a plurality of beam plates 5.

As shown in fig. 4, the sleeper beam 4 is a concrete prefabricated member, at least 4 anchor bolts 41 are arranged on each sleeper beam, the lower half part of each anchor bolt 41 is embedded in the sleeper beam concrete, and the upper half part of each anchor bolt is protruded on the top surface of the sleeper beam.

As shown in fig. 5, 6 and 7, each beam plate 5 comprises a steel panel 51, a plurality of longitudinal back ridges 52 are welded on the bottom surface of the panel along the longitudinal direction of the panel, a plurality of connecting rods 53 are welded between adjacent longitudinal back ridges, a transverse back ridge 54 is welded on each of two ends of the bottom surface of the panel along the transverse direction of the panel, at least two anchoring plates 55 parallel to the panel are welded on the outer side of each transverse back ridge, and screw holes 56 are preset on the anchoring plates.

As shown in fig. 2 and 3, a plurality of sleepers 4 are laid in the lateral direction of the sidewalk with a certain space between adjacent sleepers. The plurality of beam plates 5 are sequentially laid along the longitudinal direction of the sidewalk, two ends of each beam plate 5 are respectively supported on two adjacent sleepers 4, opposite ends of the two adjacent beam plates are supported on the same sleeper and have a certain distance, each anchoring plate 55 at two ends of each beam plate respectively penetrates through an anchoring bolt 41 on the top surface of the sleeper, and the anchoring plates 55 are tightly pressed on the top surface of the sleeper 4 by screwing nuts 6 on the anchoring bolts 41.

The utility model discloses during the specific implementation, for guaranteeing sleeper beam and beam slab stable in structure, can with sleeper beam 4 buries in the former soil body 7 of interim access, and the sleeper beam top surface flushes with the soil body top surface.
