Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, and more specifically, to an assembly device for fixing the bottom beam of a photovoltaic support structure in a prefabricated house. Furthermore, it also relates to a sunroom including the aforementioned assembly device for fixing the bottom beam of a photovoltaic support structure in a prefabricated house. Background Technology

[0002] In current technology, most rooftop sunrooms use expansion bolts to fix the column bases. This method is convenient to construct, but it has a major drawback: the roof panels must be cast-in-place slabs. However, before 2010, approximately 90% of houses in China used precast perforated slabs. Due to the porous structure of these slabs, ordinary expansion bolts cannot function effectively.

[0003] In summary, how to solve the problem that expansion bolts cannot be directly used for fixing when installing photovoltaic power stations on porous prefabricated panel houses is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an assembly device for fixing the bottom beam of a photovoltaic support frame in a precast concrete house, which can solve the problem that expansion bolts cannot be used to fix the photovoltaic power station when installing a multi-hole precast concrete house.

[0005] Another objective of this invention is to provide a sunroom that includes the assembly device described above for fixing the bottom beam of a photovoltaic support structure in a prefabricated house.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An assembly device for fixing the bottom beam of a photovoltaic support structure in a prefabricated panel house, comprising:

[0008] The nesting component has a cross-section in the shape of a "Z". The nesting component includes two horizontally distributed plates and an inverted U-shaped groove between the two horizontal plates. The inverted U-shaped groove is fitted onto the upper part of the bottom beam of the support. The horizontal plates are provided with at least one mounting hole along the length direction.

[0009] Fasteners that pass through the mounting holes and connect to the ring beam at the top of the house.

[0010] In one embodiment, the horizontal plate is provided with a plurality of mounting holes at equal intervals along its length.

[0011] In one embodiment, the horizontal plate and the inverted U-shaped groove are an integral structure.

[0012] In one embodiment, the nesting member comprises a steel plate.

[0013] In one embodiment, the fastener includes an expansion bolt.

[0014] In one embodiment, the fastener is provided with an anti-loosening structure.

[0015] A sunroom includes the assembly device described in any of the above for fixing the bottom beam of a photovoltaic support structure in a prefabricated house.

[0016] In one embodiment, the device further includes a house, a ring beam disposed around the top of the house, and a photovoltaic module disposed on the top of the house. The inverted U-shaped groove of the assembly device for fixing the photovoltaic support base beam of the prefabricated house is fitted onto the upper part of the support base beam of the photovoltaic module. The fasteners of the assembly device for fixing the photovoltaic support base beam of the prefabricated house pass through the mounting holes of the assembly device for fixing the photovoltaic support base beam of the prefabricated house and are connected to the ring beam.

[0017] In one embodiment, the ring beam includes reinforcing bars for forming a frame and concrete poured within the reinforcing bars.

[0018] In one embodiment, the ring beam is provided with a plurality of assembly devices for fixing the photovoltaic support base beam of the prefabricated panel house at intervals along the circumference.

[0019] When using the assembly device for fixing the base beam of a photovoltaic bracket in a precast concrete house provided by this utility model, when installing a photovoltaic power station in a multi-hole precast concrete house where expansion bolts cannot be directly used for fixing, firstly, the bracket base beam is installed on the ring beam at the top of the house. Then, multiple assembly devices for fixing the base beam of the photovoltaic bracket in the precast concrete house are set at intervals on the bracket base beam, that is, multiple nesting pieces are set at intervals along the length of the bracket base beam, so that the inverted U-shaped groove is fitted on the upper part of the bracket base beam. After that, fasteners are passed through the mounting holes and connected to the ring beam at the top of the house to fix the inverted U-shaped groove to the ring beam with fasteners (such as expansion bolts), that is, the pressing and fixing operation of the bracket base beam and the ring beam is realized. Finally, the photovoltaic bracket is assembled and connected to the bracket base beam to complete the photovoltaic power station installation operation of the multi-hole precast concrete house.

[0020] This application addresses the issue of using ordinary expansion bolts directly on precast panels. It employs a conversion method by arranging support base beams to transfer the force of the columns to these beams. Then, by fixing these support base beams around the perimeter of the roof, the entire power station is integrated into a single unit, resulting in a more rational stress distribution. Finally, the support base beams are fixed using this device on the ring beams around the perimeter of the building. Since the ring beams are made of concrete, expansion bolts can be used as fasteners. This device effectively secures the support base beams (i.e., the foundation for the photovoltaic modules) without causing irreversible damage to the roof panels. The inverted U-shaped grooves effectively nest the support base beams, ensuring a better fit and fixation to the roof ring beams, thereby guaranteeing the safety performance of the photovoltaic modules and their supports.

[0021] In summary, the assembly device for fixing the bottom beam of photovoltaic brackets in prefabricated houses provided by this utility model can solve the problem that expansion bolts cannot be directly used for fixing when installing photovoltaic power stations in multi-hole prefabricated houses.

[0022] In addition, this utility model also provides a sunroom that includes the above-mentioned assembly device for fixing the bottom beam of the photovoltaic support for prefabricated panel houses. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this utility model is to provide an assembly device for fixing the bottom beam of a photovoltaic support frame in prefabricated panel houses, which solves the problem that expansion bolts cannot be directly used for fixing photovoltaic power stations in multi-hole prefabricated panel houses. Another core aspect of this utility model is to provide a sunroom that includes the aforementioned assembly device for fixing the bottom beam of a photovoltaic support frame in prefabricated panel houses.

[0033] Please refer to Figures 1 to 3 This specific embodiment provides an assembly device for fixing the bottom beam of a photovoltaic support structure in a prefabricated panel house, comprising:

[0034] The nesting component 1 has a cross-section in the shape of a "Z". The nesting component 1 includes two horizontally distributed plates 11 and an inverted U-shaped groove 12 between the two horizontally distributed plates 11. The inverted U-shaped groove 12 is fitted onto the upper part of the support bottom beam 4. The horizontally distributed plates 11 have at least one mounting hole 13 along the length direction.

[0035] Fastener 2, which passes through mounting hole 13 and connects to ring beam 3 at the top of house 6.

[0036] It should be noted that the roof of building 6 is surrounded by ring beams 3, which are rectangular in structure. Figure 4 As shown, the number and location of this device can be determined according to the actual situation and needs. Moreover, since the ring beam 3 is a concrete structure, expansion bolts can be directly driven into the concrete for fastening. The support bottom beam 4 can also be set as a rectangular structure, or support bottom beams 4 can be set on the top of the ring beam 3. Then, the inverted U-shaped groove 12 is fitted onto the upper part of the support bottom beam 4, and the horizontal plate 11 is attached to the top of the ring beam 3. Then, the fasteners 2 are connected to the ring beam 3 through the mounting holes 13, so that the support bottom beam 4 can be press-fitted and fixed on the ring beam 3 by this device.

[0037] When using the assembly device for fixing the photovoltaic support base beam of a precast concrete house provided by this utility model, when installing a photovoltaic power station on a multi-hole precast concrete house that cannot be directly fixed with expansion bolts, firstly, install the support base beam 4 on the ring beam 3 at the top of the four sides of the house 6. Then, set multiple assembly devices for fixing the photovoltaic support base beam of the precast concrete house at intervals on the support base beam 4, that is, set multiple nesting parts 1 at intervals along the length direction of the support base beam 4, so that the inverted U-shaped groove 12 is fitted on the upper part of the support base beam 4. Then, pass the fastener 2 through the mounting hole 13 and connect it to the ring beam 3 at the top of the house 6, so as to fix the inverted U-shaped groove 12 to the ring beam 3 by the fastener 2 (such as expansion bolts), that is, realize the press-fit fixing operation of the support base beam 4 and the ring beam 3. Finally, assemble and connect the photovoltaic support to the support base beam 4 to complete the photovoltaic power station installation operation of the multi-hole precast concrete house.

[0038] This application addresses the issue of using ordinary expansion bolts directly on precast panels. It employs a conversion method by arranging support base beams 4, transferring the force of the columns to the support base beams 4. Then, by fixing the support base beams 4 around the top of the building 6, the entire power station is integrated into a single unit, resulting in a more rational stress distribution. Finally, the support base beams 4 are fixed using this device, with the fixing position on the ring beams 3 around the building 6. Because the ring beams 3 around the building 6 are made of concrete, expansion bolts can be used as fasteners 2 for fixation. This device effectively and firmly fixes the support base beams 4 (i.e., the support foundation for the photovoltaic modules 5) without causing irreversible damage to the roof panel. The inverted U-shaped grooves 12 effectively nest the support base beams 4, allowing them to be better fitted and fixed to the ring beams 3 of the roof, thereby ensuring the safety performance of the photovoltaic modules 5 and their supports.

[0039] In summary, the assembly device for fixing the bottom beam of photovoltaic brackets in prefabricated houses provided by this utility model can solve the problem that expansion bolts cannot be directly used for fixing when installing photovoltaic power stations in multi-hole prefabricated houses.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, the horizontal plate 11 has multiple mounting holes 13 at equal intervals along its length. For example, three, four or five mounting holes 13 can be set at equal intervals on the horizontal plate 11, but it is not advisable to set too many mounting holes 13, so as to avoid excessive frequency and intensity of operators manually connecting the fasteners 2 through the mounting holes 13 to the ring beam 3 at the top of the house 6 (i.e., driving expansion bolts into the ring beam 3).

[0041] In one embodiment, the horizontal plate 11 and the inverted U-shaped groove 12 are an integral structure to improve the structural strength of the device and reduce the assembly process. By using this device, the support base beam 4 can be firmly fixed to the roof ring beam 3, so that the support base beam 4 is better fitted and fixed to the roof, ensuring the safety of the photovoltaic support.

[0042] In one embodiment, the nesting member 1 comprises a steel plate. For example, the nesting member 1 can be made of carbon structural steel plate with suitable yield strength and tensile strength, so that the nesting member 1 performs well in bearing heavy loads and stresses, and can meet the fastening and stability requirements of various complex projects.

[0043] In one embodiment, the fastener 2 includes an expansion bolt.

[0044] It should be noted that an expansion bolt consists of a head and a threaded rod (a cylinder with external threads) connected to the head. The expansion bolt requires a nut for fastening two parts with through holes; this type of connection is a detachable connection. Expansion bolts offer the advantages of speed and convenience (immediate load-bearing capacity), avoiding the complexities of installing pre-embedded anchor bolts, and are widely used in the construction industry and equipment installation projects.

[0045] In one embodiment, the fastener 2 is provided with an anti-loosening structure.

[0046] It should be noted that the fixing principle of expansion bolts is to generate frictional gripping force through the wedge-shaped slope that causes expansion. Specifically, the tapered structure of the expansion bolt head compresses the outer sleeve when the nut is tightened, causing it to expand and conform to the hole wall, thereby achieving a fixing effect. However, traditional expansion bolts are susceptible to loosening due to vibration, as they rely on a single frictional gripping force, which is easily weakened by frictional attenuation under load and vibration. By incorporating anti-loosening structural components on fastener 2, the risk of vibration-induced loosening of the expansion bolt can be effectively reduced.

[0047] For example, the anti-loosening structure includes a combination of tongues and locking blocks. Specifically, an outer washer connects to a trapezoidal cylinder, with four tongues at the end equipped with locking blocks. During installation, the tongues are pre-expanded to fit against the hole wall, and then the expansion bolt pushes the mounting cylinder to fully expand the tongues. The locking blocks then embed into the grooves of the connecting cylinder and lock in place. This pre-expansion increases friction and prevents synchronous rotation, while the mechanical locking of the locking blocks enhances the vibration resistance of the expansion bolts. Alternatively, the anti-loosening structure may include a double-nut design: the countersunk bolt has positive and negative threads on its upper part, which, together with two opposite nuts, form a mechanical self-locking mechanism. Other structures can also be used to prevent the expansion bolts from loosening due to vibration. In addition to the above-mentioned assembly device for fixing the bottom beam of a photovoltaic bracket in prefabricated houses, this utility model also provides a sunroom that includes the assembly device for fixing the bottom beam of a photovoltaic bracket in prefabricated houses disclosed in the above embodiments. The structure of other parts of this sunroom is described in the prior art and will not be repeated here.

[0048] In one embodiment, such as Figure 5 As shown, it also includes a house 6, a ring beam 3 around the top of the house 6, and a photovoltaic module 5 on the top of the house 6. The inverted U-shaped groove 12 of the assembly device for fixing the photovoltaic bracket bottom beam of the prefabricated house is fitted on the upper part of the bracket bottom beam 4 of the photovoltaic module 5. The fastener 2 of the assembly device for fixing the photovoltaic bracket bottom beam of the prefabricated house passes through the mounting hole 13 of the assembly device for fixing the photovoltaic bracket bottom beam of the prefabricated house and is connected to the ring beam 3.

[0049] In one embodiment, the ring beam 3 includes reinforcing bars for forming a frame and concrete poured within the reinforcing bars.

[0050] It should be noted that ring beam 3 refers to a closed-loop reinforced concrete beam component installed horizontally along the masonry wall in the building 6. It is typically installed at foundation walls, eaves, and floor slabs. Ring beam 3 enhances the overall integrity and stability, mitigating adverse effects. Specifically, ring beam 3, in conjunction with floor slabs and structural columns, increases the overall stiffness and stability of building 6. For example, just as a clamp around a bucket increases its shear and tensile strength, ring beam 3 also enhances the shear and tensile strength of masonry. Ring beam 3 strengthens the connection between longitudinal and transverse walls, improving the overall integrity of building 6. As an edge component of the floor slab, it increases the horizontal stiffness of the floor slab, reduces the relevant free length of the walls, and improves the stability of the walls. Furthermore, ring beam 3 prevents adverse effects on building 6 caused by uneven foundation settlement or large vibration loads.

[0051] In one embodiment, such as Figure 4 As shown, the ring beam 3 is provided with multiple assembly devices for fixing the photovoltaic support base beam of the precast panel house at intervals along the circumference. For example, five assembly devices for fixing the photovoltaic support base beam of the precast panel house can be set at equal intervals on each side of the ring beam 3, and the inverted U-shaped grooves 12 on the two perpendicular sides do not affect each other.

[0052] In addition, it should be noted that the orientation or positional relationship indicated by "top" and "bottom" in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Similar or identical parts between embodiments can be referred to interchangeably. Any combination of all embodiments provided by this utility model is within the protection scope of this utility model and will not be elaborated upon here.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
