Description

Technical Field:

[0001] The utility model belongs to the technical field of roof photovoltaic installation structures, specifically referring to a photovoltaic installation structure for precast slab roofs with ventilators. Background Art:

[0002] The photovoltaic support is a special component required for installing and fixing photovoltaic panels in a photovoltaic power generation system. In existing buildings, photovoltaic panels are laid on the roof through photovoltaic supports to effectively utilize the space resources of the relatively large roof area. However, due to the influence of the position and height of the exhaust ventilator on the roof, the ventilator has a large impact area on the shadow of the main roof, resulting in a very limited area available for photovoltaic installation on the roof, and greatly reducing the effective area of photovoltaic installation on the roof. At the same time, the precast cement slab roof has a lower load-bearing capacity compared to the cast-in-place cement roof, and the conventional installation method cannot effectively bear the installation of the photovoltaic support and its photovoltaic panels. Summary of the Invention:

[0003] The purpose of the utility model is to provide a photovoltaic installation structure for precast slab roofs with ventilators, which directly installs the photovoltaic installation support on the top surface of the exhaust ventilator, raises the photovoltaic installation support by means of columns, so that the roof photovoltaic and the ventilator photovoltaic form an integral whole, avoiding the influence of the ventilator shadow area on photovoltaic power generation, and at the same time making the main force of the photovoltaic support installation act on the exhaust ventilator, dispersing and reducing the load-bearing of the precast cement slab roof, and meeting the requirements of photovoltaic installation.

[0004] The utility model is realized as follows:

[0005] A photovoltaic installation structure for precast slab roofs with ventilators includes a precast cement slab roof and an exhaust ventilator arranged on the precast cement slab roof. The top surface of the exhaust ventilator is fixedly provided with a photovoltaic installation support. The outer end of the photovoltaic installation support extends outward beyond the exhaust ventilator and is fixedly installed on the precast cement slab roof through columns. The top surface of the exhaust ventilator is formed by the main beam of the ventilator supporting the color steel tile of the ventilator through C-shaped steel of the ventilator. The photovoltaic installation support is fixedly connected with the C-shaped steel of the ventilator through a crossbar fixing component and fastening screws;

[0006] Or the top surface of the exhaust ventilator is a cast-in-place roof slab, and the photovoltaic installation support is fixedly connected with the cast-in-place roof slab through a crossbar fixing component and fastening bolts.

[0007] In the above-mentioned photovoltaic installation structure for precast slab roofs with ventilators, a triangular connecting piece is hinged at the top of the column. The outer end of the photovoltaic installation support is fixedly connected with the triangular connecting piece through a crossbar fixing component and fastening screws. The bottom end of the column is fixedly connected with a cement pier through a buried fixing component. The cement pier is arranged at the joint gap between two adjacent precast cement slab roofs.

[0008] In the above-mentioned photovoltaic installation structure on the precast slab roof with a ventilator, the embedded fixing component includes a support base arranged on the cement pier, and the support base is fixedly connected to a U-shaped embedded bolt embedded in the cement pier. The bottom end of the column is fixedly connected to the support base through a fastener.

[0009] In the above-mentioned photovoltaic installation structure on the precast slab roof with a ventilator, the crossbar fixing component includes a crossbar fixing frame. A plastic wing nut capable of sliding up and down is arranged in the crossbar fixing frame. The plastic wing nut is fixedly connected to the photovoltaic installation bracket through a fixing bolt. The fastening screw or fastening bolt penetrates through the crossbar fixing frame and is screwed and fixed on the ventilator C-shaped steel or the cast-in-place roof slab.

[0010] In the above-mentioned photovoltaic installation structure on the precast slab roof with a ventilator, the fastening bolt is an expansion bolt, and the expansion bolt is fixedly connected to the cast-in-place roof slab through a chemical anchor bolt agent.

[0011] In the above-mentioned photovoltaic installation structure on the precast slab roof with a ventilator, the fastening screw is a dovetail screw.

[0012] The prominent advantages of the present utility model compared with the prior art are:

[0013] 1. The present utility model is reasonably designed, has a stable structure and is convenient for installation. The photovoltaic installation bracket is directly erected on the top surface of the exhaust ventilator, and the photovoltaic installation bracket is lifted by means of the column, so that the roof photovoltaic and the ventilator photovoltaic form a whole, avoiding the influence of the shadow area of the ventilator on photovoltaic power generation. At the same time, the main force of the photovoltaic bracket installation is on the exhaust ventilator, dispersing and reducing the load on the precast cement board roof, meeting the requirements of photovoltaic installation.

[0014] 2. In order to solve the problem of roof load-bearing, the photovoltaic bracket is mainly installed and fixed on the exhaust ventilator. The outer end of the photovoltaic installation bracket extends outward beyond the exhaust ventilator and is dispersedly fixed and erected on the precast cement board roof through columns, that is, the load-bearing at the joint gap of the precast cement board roof is relatively better.

Specific implementation manner:

[0020] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —4:

[0021] Embodiment 1:

[0022] A PV installation structure for a precast slab roof with an air vent, including a precast cement board roof 2 and an exhaust air vent arranged on the precast cement board roof 2. The top surface of the exhaust air vent is fixedly provided with a PV installation bracket 3. The outer end of the PV installation bracket 3 extends outward beyond the exhaust air vent and is fixedly installed on the precast cement board roof 2 through a column 4. The top surface of the exhaust air vent is formed by a main air vent beam 5 supporting a color steel tile 7 for the air vent through a C-shaped steel 6 for the air vent. The PV installation bracket 3 is fixedly connected to the C-shaped steel 6 for the air vent through a cross arm fixing assembly and a fastening screw 8;

[0023] The present utility model has a reasonable design, a stable structure and is convenient for installation. By directly installing the PV installation bracket 3 on the top surface of the exhaust air vent and using the column 4 to raise the cooperation distance between the PV installation bracket 3 and the precast cement board roof 2, the roof PV and the air vent PV form an integral whole, avoiding the influence of the air vent shadow area on PV power generation.

[0024] Among them, considering that the top surface of the exhaust air vent often has an inverted V-shaped structure with a higher middle and lower sides, the PV installation brackets 3 are respectively arranged relatively on both sides of the top surface of the exhaust air vent, and the PV installation brackets 3 are inclined. Therefore, in order to enable the column 4 to be stably connected between the PV installation bracket 3 and the precast cement board roof 2, the top of the column 4 is hinged with a triangular connecting piece 11, and the outer end of the PV installation bracket 3 is fixedly connected to the triangular connecting piece 11 through a cross arm fixing assembly and a fastening screw 8;

[0025] At the same time, considering that the load weight of the precast cement board roof 2 is relatively light, in order to stably support the PV installation bracket 3, the bottom end of the column 4 is fixedly connected to the cement pier 12 through an embedded fixing assembly. The cement pier 12 is arranged at the joint gap between two adjacent precast cement board roofs 2. That is, the load bearing at the joint gap of the precast cement board roof 2 is relatively better.

[0026] Furthermore, the pre-embedded fixing component can be a plug-in base directly pre-embedded in the cement pier 12, and the bottom end of the column 4 is inserted into the plug-in base. In this embodiment, the specific structure of the pre-embedded fixing component is as follows: The pre-embedded fixing component includes a support base 13 provided on the cement pier 12, and the support base 13 is fixedly connected to a U-shaped pre-embedded bolt 14 pre-embedded in the cement pier 12. The bottom end of the column 4 is fixedly connected to the support base 13 through a fastener.

[0027] Furthermore, the cross-arm fixing component can directly adopt sheet metal parts to be respectively connected to the photovoltaic mounting bracket 3 and the air vent C-shaped steel 6 or the cast-in-place roof slab 9 or the triangular connecting piece 11. In this embodiment, the cross-arm fixing component includes a cross-arm fixing frame 15, and a plastic wing nut 16 capable of sliding up and down is arranged in the cross-arm fixing frame 15. The plastic wing nut 16 is fixedly connected to the photovoltaic mounting bracket 3 by a fixing bolt 17, and the fastening screw 8 or the fastening bolt 10 penetrates through the cross-arm fixing frame 15 and is fixedly connected to the air vent C-shaped steel 6 or the cast-in-place roof slab 9 by screwing.

[0028] In order to ensure that the photovoltaic mounting bracket 3 can be firmly fixed on the C-shaped steel, the fastening screw 8 is a dovetail screw.

[0029] Embodiment 2:

[0030] This embodiment has basically the same structure as the above Embodiment 1, and the main difference is that: the top surface of the exhaust air vent is a cast-in-place roof slab 9, and the photovoltaic mounting bracket 3 is fixedly connected to the cast-in-place roof slab 9 through a cross-arm fixing component and a fastening bolt 10.

[0031] In order to ensure that the photovoltaic mounting bracket 3 can be firmly fixed on the cast-in-place roof slab 9, the fastening bolt 10 is an expansion bolt, and the expansion bolt is fixedly connected to the cast-in-place roof slab 9 through a chemical anchor bolt agent.
