The present invention discloses a flat plate deformation joint structure for a parking structure, comprising a structural plate 1 of a parking structure and a structural plate 2 adjacent thereto, a deformation joint is arranged between the structural plate 1 and the structural plate 2; the deformation joint comprises an expansion joint located between the structural plate 1 and the structural plate 2, F-shaped steels are arranged on the structural plate 1 and the structural plate 2 on both sides of the expansion joint, respectively, a water stop is arranged between the oppositely arranged F-shaped steels, an expansion joint cover plate is arranged across the structural plate 1 and the structural plate 2, and one end of the expansion joint cover plate is fixedly connected to the F-shaped steel on one side; the F-shaped steel on the other side and the expansion joint cover plate are movably installed by a sliding plate. The present invention provides a method for making a flat plate deformation joint for a parking structure, which ensures that the buildings on both sides can be freely displaced in horizontal bidirectional directions, has a wide range of application for the horizontal displacement requirements, has a good waterproof effect, can meet the requirements of smooth vehicle passage, has low noise, and is easy to install and maintain.

This utility model discloses a photovoltaic module installation structure for the side of a traffic road, comprising: vertical columns spaced apart in the left-right direction, with a support plate on the front side of the vertical columns; connectors, with their left and right ends supported by corresponding support plates and connected and fixed to the support plates; a fixing component including a connecting block and a pressure block, the connecting block being connected to the connector, the pressure block being connected to the front end of the connecting block and protruding vertically from the connecting block, the pressure block, the connecting block, and the connector forming a groove; and a photovoltaic module, with its bottom and top embedded in the corresponding groove and pressed by the pressure block to fit snugly against the connector. This utility model achieves the positioning, installation, and fixing of the photovoltaic module by embedding its bottom and top into the groove and applying pressure with the pressure block to ensure a tight fit with the connector, thereby reducing installation gaps, avoiding vibration and noise caused by installation gaps, simplifying installation steps, reducing installation time and labor costs, and improving construction efficiency.

The utility model relates to the field of highway facilities, and discloses a highway sound barrier acoustic board which comprises a bottom plate, the bottom plate is fixed on the bottom face of an acoustic board body, a water tank is fixed on the top face of the acoustic board body, an arc-shaped sound insulation board is fixed on the top face of the water tank, and a guide rail is fixed on the front side of the outer wall of the water tank. And a water pump is fixed to the left side of the outer wall of the water tank, a connecting pipe is fixedly communicated between the input end of the water pump and the water tank, and a conveying hose is fixedly communicated between the output end of the water pump and the spray head. According to the sound absorption board, dust, dirt and other sundries on the sound absorption board body can be removed easily, so that the sound absorption performance of the sound absorption board body is kept, traffic noise can be effectively reduced, and the comfort level of the surrounding environment and residents is guaranteed.

The utility model discloses a high-toughness low-noise ultrathin asphalt wearing layer pavement structure, which belongs to the technical field of asphalt pavements, aims at solving the problem that the service life of the pavement and the surrounding living life are influenced by low pavement toughness and high noise, and comprises a base layer and a metal woven mesh, the metal woven mesh is paved on the top surface of the base layer, and a subbase layer is arranged right above the base layer; the top face of the metal woven mesh makes contact with the ground of the subbase layer, a waterproof adhesion layer is arranged on the top face of the subbase layer, and an asphalt concrete layer is laid over the waterproof adhesion layer. The asphalt pavement glass fiber grating has excellent heat insulation performance, can effectively reduce road traffic noise and air pollutant emission, also has a good isolation effect, can prevent external objects from entering a vehicle to cause safety problems, can effectively improve the road beauty, and has a good application prospect. And meanwhile, the materials have the advantages of high impact resistance and high wear resistance, so that the materials are very easy to repair or replace.
