Description

A fixed structure for installing photovoltaic modules on concrete structure factory house panels

Technical field

The utility model relates to a photovoltaic component rooting structure, specifically to a photovoltaic component installation and fixing structure for concrete structure factory house panels.

Background technique

According to the relevant requirements of the "General Specifications for Building Energy Saving and Renewable Energy Utilization" GB55015-2021/5.2, new buildings should be equipped with solar systems.

Solar power generation systems are divided into off-grid power generation systems, grid-connected power generation systems and distributed power generation systems.

Distributed power generation system refers to the configuration of smaller photovoltaic power supply systems at the user site or close to the power consumption site to meet the needs of specific users and support the economic operation of the existing distribution network.

At present, under the premise of ensuring waterproofing, fireproofing, and airtightness, portal steel structure buildings are mainly equipped with building integrated photovoltaic systems (BIPV), and concrete rack structures and concrete frame structures are mainly equipped with roof solar photovoltaic power generation systems (BAPV).

The roof trusses are composed of roof trusses (or roof beams), columns and foundations. The columns are hinged to the roof trusses and rigidly connected to the foundation. It is mainly used in single-story factory buildings. It consists of roof trusses, columns and foundations to form transverse plane racks, which is the main load-bearing system of the factory. The plane racks are then connected through longitudinal components such as roof panels, crane beams, supports, etc. to form an overall spatial structure. .

In the row frame system, the column tops are connected with large roof trusses or trusses, and then covered with prefabricated roof panels. At present, there are five ways to install photovoltaic modules in concrete structure factories: (1) Set embedded parts in the concrete prefabricated roof panels, weld the embedded parts to the photovoltaic brackets, and use glue or clamps to fix the photovoltaic modules on the brackets; (2) In When pouring the roof of the cast-in-place concrete frame structure, embedded parts are installed, and the embedded parts are welded to the photovoltaic brackets, and the photovoltaic modules are fixed with glue or clamps on the brackets; (3) Adding a layer of steel structure to the concrete structure through glue joints or clamps Fix photovoltaic modules; (4) Fix the photovoltaic bracket through cement load-bearing blocks, and use glue joints or clamps to fix the photovoltaic modules on the bracket; (5) Set stress points through surrounding buildings and structures to fix the photovoltaic bracket, and use glue joints or clamps on the bracket Fixed photovoltaic modules.

Problems with the way existing concrete structure factory buildings install photovoltaic modules include: (1) The design is imperfect and it will be difficult to add photovoltaic modules later due to insufficient roof load and wind load; (2) Large roof panels are thin and embedded parts are easily pulled due to stress. The building envelope will be damaged due to pulling; (3) Adding steel structure as a stress point will result in high one-time investment cost; (4) Poor anti-corrosion performance; (5) The structure is complex, the physical appearance does not match the simple style of the building, and the appearance image is poor.

Therefore, it is necessary to design a photovoltaic module installation structure that can effectively resist wind load while ensuring the integrity and integrity of the roof. The photovoltaic module has a simple and elegant appearance, saves investment, has a bracket design that facilitates maintenance, and has good anti-corrosion performance.

Detailed ways

As shown in Figure 1-3, a structure for installing and fixing photovoltaic modules for roof panels in a concrete structure factory includes a digit-shaped component 1 arranged in the joint of two concrete roof panels 3. The digit-shaped component 1 has an H fixedly installed on the top. The base connecting member 2 is in the shape of a base, and the bottom is snap-connected with the concrete roof panel 3; the zigzag-shaped member 1 is made up of two U-shaped structures 11 with opposite opening directions.

During construction, firstly, the U-shaped structure 11 of the several-shaped member 1 is clamped on the edge of the concrete roof panel 3 (in order to prevent dislocation and shaking, it can be fixed with the embedded reinforcement of the concrete roof panel 3 by binding or welding), and then Lift the concrete roof panels 3 to the roof trusses 5 for roof installation. After the two concrete roof panels 3 are aligned, the U-shaped structure 11 assumes the configuration shown in Figure 2, and the joints meet the process requirements, high-strength concrete is poured into the joints. Grouting material. After the grouting material is initially set, the H-shaped foundation connecting component 2 and the digit-shaped component 1 are welded and fixed. Subsequently, the roof waterproof insulation layer 4 is laid according to the construction engineering design specifications. The exposed parts of the digit-shaped component 1 are covered with anti-corrosion materials (environmentally friendly materials) according to the use environment. Oxycoal tar or epoxy resin) treatment.
