Description

Technical Field

[0001] This utility model belongs to the field of building equipment technology, specifically relating to a positioning device for pre-embedded bolts in concrete supports of roof distributed photovoltaic brackets. Background Technology

[0002] When installing distributed photovoltaic (PV) systems on existing concrete roofs, cast-in-place concrete supports are typically used as the foundation structure. Bolts are pre-embedded in these supports for connecting the foundation to the upper support structure. There are two methods for constructing the concrete support foundation: one is to cast it on-site on the roof, and the other is to cast it centrally and then transport the finished product for use. However, regardless of the method, on-site concrete pouring is required. Since the supports typically lack structural reinforcement and the U-shaped embedded round steel has no fixing measures, the position of the embedded bolts cannot be controlled due to the disturbance caused by the concrete pouring process. This makes it difficult to guarantee the installation accuracy of the upper support structure, and the connection between the uprights and the supports is prone to misalignment and deformation, resulting in problems such as upright tilting and purlin deformation, affecting the strength and overall stability of the PV system. Furthermore, the leveling and alignment work during installation is extensive, disrupting normal on-site construction. Utility Model Content

[0003] To address the issue of misalignment of pre-embedded bolts in the aforementioned concrete support foundation, and in order to ensure the accuracy and quality of subsequent support installation, thereby controlling the strength and overall stability of the support and reducing the workload of leveling and correction during installation, this utility model proposes a casting and positioning device for pre-embedded bolts in the concrete support of roof distributed photovoltaic support.

[0004] A positioning device for pre-embedded bolts in concrete supports for roof distributed photovoltaic systems is characterized by comprising a cylindrical mold, an annular positioning sleeve, positioning keels, a positioning steel plate, and U-shaped pre-embedded bolts. The inner ring edge of the annular positioning sleeve is parallel to and fixed to the upper edge of the cylindrical mold. Two positioning keels are symmetrically welded parallel to each other on the inner side of the annular positioning sleeve. A positioning steel plate is welded to the middle position of the positioning keels, and four pre-embedded bolt holes are opened on the positioning steel plate. The U-shaped pre-embedded bolts are passed through the bolt holes and fixed.

[0005] Furthermore, the annular positioning sleeve is made of angle steel, square steel, or steel plate welded together.

[0006] The beneficial effects of this utility model are as follows: it effectively fixes the pre-embedded bolts during the concrete support pouring process, ultimately ensuring that the planar position and exposed thread length of the pre-embedded bolts meet the installation accuracy requirements after the concrete support foundation is poured. After the concrete has initially set, the positioning device can be removed and reused, offering high versatility, reducing cost investment, effectively controlling the installation accuracy of the pre-embedded bolts in the concrete support, and ensuring the quality of the support construction.

[0010] Example 1: A positioning device for pre-embedded bolts in concrete supports for rooftop distributed photovoltaic systems, comprising a cylindrical mold 1, an annular positioning sleeve 2, positioning keels 3, positioning steel plates 4, and U-shaped pre-embedded bolts 6. The annular positioning sleeve 2 is made of angle steel with a specification of L50*50mm and a thickness of 5mm, bent and welded. The inner ring edge of the annular positioning sleeve 2 is parallel to and fixed to the upper edge of the cylindrical mold 1. Two positioning keels 3 are symmetrically welded parallel to each other on the inner side of the annular positioning sleeve 2. The positioning keels 3 are made of 30*30mm square steel. A 3mm positioning steel plate 4 is welded to the middle position of the positioning keel 3, and four pre-embedded bolt holes 5 are opened on the positioning steel plate 4. The U-shaped pre-embedded bolts 6 are passed through the bolt holes 5 and fixed.

[0011] Concrete supports are poured in cylindrical molds. During the process, U-shaped pre-embedded bolts 6 provide effective fixation, ensuring that the plane position and exposed thread length of the U-shaped pre-embedded bolts 6 meet the installation accuracy requirements after the concrete support foundation is poured.
