Description

Technical Field

[0001] The utility model belongs to the technical field of household photovoltaic construction engineering applications, and particularly relates to a cable support on a pitched roof. Background Art

[0002] With the rapid installation of photovoltaic power stations, to meet market demand, photovoltaic power stations also need to be installed in some coastal areas with relatively large wind and snow loads. However, the strength of traditional pre-galvanized aluminum-magnesium supports is limited. On the premise that the support structure meets safety requirements, cost reduction and efficiency improvement of the photovoltaic system have gradually been emphasized. To increase the installed capacity while reducing reinforcement costs and being applicable to some coastal areas with relatively large wind and snow loads, the demand for a cable support on a pitched roof has gradually attracted attention. Moreover, most of the existing support structures use tile removal to increase the hook to reduce the bending moment on the inclined beam. However, fixing the hook by removing tiles may cause roof leakage and affect the customer experience.

[0003] To solve the deficiencies of the existing technology, people have conducted long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a household photovoltaic construction foundation that does not damage the original structure of the tile roof [CN220190721U], which includes a house body, a photovoltaic module, a wall support assembly, an inclined beam, a rear tie rod, a ridge diagonal brace, etc.; among them, the photovoltaic module is installed on the inclined beam.

[0004] The above solution solves the problem of roof leakage caused by the existing support structure to a certain extent, but there are still many deficiencies in this solution. For example, one end of the inclined beam is fixedly connected to the wall through a wall diagonal brace, and the other end of the inclined beam is connected to the rear tie rod through a ridge diagonal brace, and the rear tie rod is connected to another wall through a wall diagonal brace. To ensure the reinforcement effect of the inclined beam, the cost is too high. Summary of the Invention

[0005] The purpose of the utility model is to provide a cable support on a pitched roof for the above problems.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A cable support on a pitched roof, comprising a sloping beam connected to the south slope of the pitched roof through an installation and fixation structure. The upper end of the sloping beam extends to one side above the south slope of the pitched roof and is connected to the upper end of a backstay extending along the north slope of the pitched roof through a ridge triangular connecting piece. The lower end of the sloping beam extends to one side below the south slope of the pitched roof and is connected to a wall through a south side triangular fixing structure. The lower end of the backstay extends to one side below the north slope of the pitched roof and is connected to the wall through a north side triangular fixing structure. A cable member is arranged between the sloping beam and the backstay. The cable member sequentially passes through the sloping beam, the ridge triangular connecting piece, and the backstay. The end of the cable member is connected to the south side triangular fixing structure and / or the north side triangular fixing structure through a cable pulling and locking structure. And the strength of the sloping beam can be improved through the cable member, and the reinforcement cost of the sloping beam can be effectively reduced, and the installed capacity can be increased.

And the supporting effect on the sloping beam can be further improved through the south side triangular bracing cross brace and the south side base connecting piece, and the installation stability of the sloping beam can be ensured.

[0009] In the above-mentioned cable support on a pitched roof, the north side triangular fixing component includes a first north side triangular connecting piece arranged between one end of the north side triangular bracing strut and the lower end of the backstay.

The south cable section and the north cable section are of an integral structure. When the locking force of the cable member tightens the south cable section and the north cable section, part of the force on the inclined beam can be transmitted to the north and south side walls, thereby improving the reinforcement effect of the inclined beam.

[0011] In the above cable support on an inclined roof, the cable pulling and locking structure includes a south cable pulling and locking assembly arranged between the south cable section of the cable member and the south triangular brace diagonal brace, and a north cable pulling and locking assembly arranged between the north cable section of the cable member and the north triangular brace diagonal brace.

Through the north turnbuckle, the cable member can be fixedly connected to the north locking cable, and the distance between the cable member and the north locking cable can be easily adjusted, facilitating installation and adjustment by the user.

[0014] In the above cable support on an inclined roof, the installation and fixing structure includes a number of T-shaped braces arranged between the south slope of the inclined roof and the inclined beam. The top of the T-shaped brace is fixedly welded or bolted to the inclined beam to ensure the connection stability between the T-shaped brace and the inclined beam. The bottom of the T-shaped brace abuts against the south slope of the inclined roof. When the cable member is tightened by the locking force to be straightened and taut, part of the force on the inclined beam can be transmitted to the north and south side walls, effectively reducing the force on the inclined beam, thereby reducing the pressure on the T-shaped brace by the inclined beam, effectively preventing damage to the roof tiles caused by the pressure of the T-shaped brace, and reducing the risk of roof tile leakage.

[0015] In the above cable bracket on an inclined roof, a photovoltaic module is provided on the side of the inclined beam away from the south slope of the inclined roof, and the photovoltaic module is fixed on the inclined beam through a plurality of guide rails.
