Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular to a bracket and an installation method for photovoltaic installation outside an existing building. Background Art

[0002] my country has a huge stock of multi-story existing buildings. Most of these buildings were built in different historical periods, with different design styles and structural characteristics, but they generally face the need for green transformation and energy efficiency improvement. Using photovoltaic technology to connect to the grid for power generation has become one of the important ways to green transformation of existing buildings. In existing high-rise buildings, photovoltaic power is usually installed on the roof of multi-story existing buildings to connect to the grid for power generation. In the actual installation process, some relatively square and regular multi-story buildings have a small roof area, so the power generation of roof photovoltaics is relatively limited. There are large areas on the facades of such buildings where photovoltaics can be applied. However, due to the current development of photovoltaic technology and construction methods on the exterior of existing buildings, the development of photovoltaic technology on the exterior of multi-story existing buildings is slow.

[0003] In response to this problem, the existing technical solution proposes a structural form of installing a photovoltaic bracket on the parapet. This structural form requires opening a hole in the parapet and inserting a fixing rod in the hole, connecting the mounting frame through the fixing rod, and installing the photovoltaic panel on the mounting frame. Although the installation of the photovoltaic panel can be completed in this way, this structural form will weaken the bearing capacity and stability of the parapet, and the height of the parapet is limited, which leads to a small number of installed photovoltaic panels, that is, the electric energy obtained through photovoltaic is limited; at the same time, after the photovoltaic panel is installed on the parapet through the mounting frame, the bearing capacity of the parapet is increased. When encountering severe weather (such as strong winds), the parapet structure may be damaged, and the photovoltaic equipment on the parapet will fall from a height, causing serious damage to pedestrians and equipment under the building.

The photovoltaic panel is adjusted between the first mounting components of two adjacent levels. After the control terminal in the control system obtains the photovoltaic panel reaching a preset position through the unit controller, it is fixed through the fixed base.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes a bracket for photovoltaic installation outside an existing building. The bracket ensures that the bracket can remain stable in the face of various external factors by combining a corner connecting block with a second connecting steel strand and connecting reinforcing rods between two adjacent first mounting components, thereby providing a high-strength mounting bracket, which is easy to construct and install as a whole, has a light weight, and will not impose excessive load on the roof of the existing building. The second movable connecting block and the first fixing clamp in the second mounting component are connected by a third connecting steel strand, which not only increases the flexibility of the bracket and facilitates the installation and removal of photovoltaic panels, but also makes the operation and maintenance of the photovoltaic bracket more convenient. The communication connection between the unit controller and the control terminal realizes real-time monitoring and remote control of the status of each component of the bracket, greatly reduces the operation and maintenance cost, and improves the operation and maintenance efficiency. Through the bracket, photovoltaic panels can be installed on the entire outer surface of the building, the number of photovoltaic panels installed on the outer side of the building is increased, and power generation efficiency is improved. The photovoltaic panels are installed or removed by sliding on the second vertical connecting steel strand through the second mounting component, which ensures the convenience and safety of workers' operation.

[0016] Furthermore, the bracket is fixed to the top end surface of the building body at the corner of the parapet through an installation base, which ensures the stability and reliability of the suspension assembly, makes full use of the building space, and effectively avoids the influence of the bracket on the building appearance. The stability of the bracket support is increased by the suspension arm, and the sliding part allows the second connecting steel strand to slide freely along the guide rail on the suspension arm. The position of the second connecting steel strand can be adjusted according to a preset position, thereby improving the convenience of installation. The first drive motor is connected to the unit controller, and the installer can remotely control the position of the sliding part through the control terminal. The installer does not need to use tools to install it outside the building, thereby improving the safety of the installation.

[0017] Furthermore, in this bracket, the cooperation between the second drive motor and the unit controller can accurately control the moving position of the corner connecting block on the second connecting steel strand, thereby improving the convenience of installation of the photovoltaic bracket and enabling the bracket to be fine-tuned according to actual needs. During the installation process, the second drive motor and the unit controller are used to move the corner connecting block along the second connecting steel strand, thereby reducing the workload of the installers. This bracket allows photovoltaic panels to be installed on the entire outer surface of the building, thereby increasing the number of photovoltaic panels installed and improving power generation efficiency.

[0018] Furthermore, the drive motor and the screw rod of the fixed base in the bracket, combined with the third connecting steel strand, provide stable support and adjustment functions for the photovoltaic panel, reduce the installation difficulty of the installers during the installation process, and speed up the installation efficiency.

[0019] Furthermore, there are multiple reinforcement rods in the bracket, and the multiple reinforcement rods are located on the same side end surface of the outer wall of the building. The two reinforcement rods in the first mounting components of two adjacent levels are connected by a mosaic buckle, so that the two reinforcement rods form an "X"-shaped support structure. The "X"-shaped support structure increases the support strength of the first mounting components of two adjacent levels, thereby increasing the wind resistance stiffness of the bracket, thereby preventing the bracket from colliding with the building body after being subjected to a large wind load.

The fixed seat 144 A sliding layer is arranged between the mounting seat 141, and the inner wall of the sliding layer fits the third connecting steel strand, increasing the sliding property between the third connecting steel strand 10 and the fixing seat 144 and the mounting seat 141, so that the installer can save more effort when installing the photovoltaic panel 3; wherein, the sliding layer is made of one of polytetrafluoroethylene, modified polytetrafluoroethylene, ultra-high molecular weight polyethylene and ultra-high performance polytetrafluoroethylene; when the photovoltaic panel 3 moves to the preset position on the third connecting steel strand 10, the screw rod 142 is rotated by driving the motor 143, the distance between the mounting seat 141 and the fixing seat 144 is reduced, and the photovoltaic panel 3 is fixed on the third connecting steel strand 10. A control lock 15 is installed on the side of the photovoltaic panel 3 located on the mounting fixing base 14, and the function of the control lock 15 is to enable the worker to hook with the control lock 15 through a slender rod on the roof of the building, and press down (when installing photovoltaic) or pull up (when removing photovoltaic).

[0035] The control system includes a control terminal and a unit controller, and the unit controller includes sensors and controllers. The first sensor and the first controller are installed on the sliding member 22, the second sensor and the second controller are installed on the corner connecting block 40, the third sensor and the third controller are installed on the first movable connecting block 7, the fourth sensor and the fourth controller are installed on the second movable connecting block 8, and the fifth sensor and the fifth controller are installed on the mounting seat 141; the control terminal includes a GPS signal collector, a processor and a display, and the GPS signal collector is used to collect position information of the first sensor, the second sensor, the fourth sensor and the fifth sensor, and obtain the sagging information of the first connecting steel strand 5 through the third sensor.

[0036] The technical solution proposed in the present invention is only applicable to multi-story and high-rise buildings with rectangular structural shapes. The reason is that the oblique reinforcement rods 11 on the four building facades can provide wind-resistant stiffness for the bracket of the present application, that is, no matter from which angle the wind blows towards the bracket structure of the present application, the bracket structure of the present application will not undergo significant deformation.

[0037] The present invention proposes a method for installing a bracket for photovoltaic installation outside an existing building, comprising the following steps: A suspension assembly 2 is installed on the top end surface of the building body at the corner area of ​​the parapet 1, and a second connecting steel strand 6 is vertically installed on the suspension assembly 3; Specifically, the bottom of the mounting base 20 is fixed on the top end surface of the building body at the corner position of the parapet 1, and the suspension arm 21 is installed on the mounting base 20. The bottom end surface of the suspension arm 21 is connected to one end of the second connecting steel strand 6, and the first controller and the first sensor in the unit controller are connected to the control terminal for communication; The control terminal in the control system controls the unit controller installed on the suspension assembly 2, and drives the suspension assembly 2 through the unit controller so that the second connecting steel strand 6 is parallel to the building facade, and moves the second connecting steel strand 6 to a preset position; Specifically, the control terminal in the control system obtains the position information collected by the first sensor, and enables the installer to determine the preset position through the position information. The control terminal sends a control signal to the first controller to control the first drive motor 221 to start. The first drive motor 221 drives the roller 222 to rotate, so that the U-shaped sliding block 220 moves along the guide rail under the cooperation of the limit block 223 and the limit guide groove 211. During the movement, the position information is obtained in real time by the first sensor and sent to the control terminal. When the first sensor obtains in real time that the second connecting steel strand 6 moves to the preset position, the control terminal sends a control signal to the first controller, and the first controller controls the first drive motor 221 to stop, and at the same time controls the electric push rod 230 in the first locking member 23 to push the block 231 into the corresponding slot 212 to fix the position of the second connecting steel strand 6.

[0038] A plurality of corner connection blocks 40 are installed on each second connection steel strand 6. The control system obtains the position of the corner connection block 40 through the unit controller, and adjusts the position of the corner connection block 40 so that the plurality of corner connection blocks 40 are installed at equal intervals. A first connection steel strand 5 is connected between two adjacent corner connection blocks 40 at the same height on different second connection steel strands 6. The corner connection blocks 40 connected at the same height form a first-level first installation assembly 4. Specifically, a plurality of corner connection blocks 40 are installed on each second connecting steel strand 6, and a unit controller, namely a second controller and a second sensor, is installed on the corner connection block 40. A first connecting steel strand 5 is connected between two adjacent corner connection blocks 40 at the same height on different second connecting steel strands 6. A control terminal in the control system obtains position information collected by the second sensor, and enables the installer to determine the preset position through the position information. A control signal is sent to the second controller through the control terminal to control the second drive motor 410 to start, and the second drive motor 410 drives the drive wheel 411 to rotate, so that the corner connection block 40 moves to the preset position along the second connecting steel strand 6, and the plurality of corner connection blocks 40 on the same second connecting steel strand 6 are arranged at equal intervals. When the second sensor obtains in real time that the corner connection block 40 moves to the preset position After that, the control terminal sends a control signal to the second controller, and the second controller controls the second drive motor 410 to stop, and at the same time controls the rotating member 420 to drive the roller 421 to rotate, so as to retract and release the steel belt 422, so that the anti-slip protrusion 423 on the steel belt 422 is tightly fitted to the outer wall of the second connecting steel strand 6, so as to fix the corner connecting block 40 on the second connecting steel strand 6; the first connecting steel strand 5 is connected with the first movable connecting block 7, and the first movable connecting block 7 is installed on the side end surface of the corner connecting block 40, and the corner 40 connecting blocks connected at the same height form a first-level first installation component 4, and the control terminal controls the third sensor to obtain the sagging information of the first connecting steel strand, and sends a control signal to the third controller based on the sagging information of the first connecting steel strand 5, so that the tightening motor 72 in the first movable connecting block works to tighten the first connecting steel strand 5; Connect the reinforcement rod 11 to the first connecting steel strands 5 located on the outer wall of the same side of the building in the first installation assemblies 4 of the two adjacent levels; Specifically, in the first installation assembly 4 of two adjacent levels, two reinforcement rods 11 are connected to the first connecting steel strand 5 located on the outer wall on the same side of the building. The center positions of the two reinforcement rods 11 are connected by an interlocking buckle 12, so that the two reinforcement rods 11 form an "X"-shaped support structure. The upper ends of the two reinforcement rods 11 are connected to a second fixing clamp 13, and the second fixing clamp 13 is fixed to the first connecting steel strand 5 to fix one end of the reinforcement rod 11. The other side ends of the two reinforcement rods 11 are connected to the first movable connecting block 7.

[0039] During construction, the two reinforcement rods 11 in the first installation component 4 near the bottom of the building form an "X"-shaped support structure. Construction workers are required to use a slender clamp to clamp the two end portions of the first connecting steel strand 5 in the first installation component 4 near the bottom of the building, and apply a reverse force to cooperate with the first movable connecting block 7 to tighten the first connecting steel strand 5 in the first installation component 4 near the bottom of the building. During the construction process, it is also necessary to pay attention to the fact that the second connecting steel strand 6 should always remain vertical. Specifically, it can be judged by whether the projections of the position information obtained by the first sensor and the second sensor on the horizontal plane overlap. If they overlap, it can be judged that the second connecting steel strand 6 remains vertical. This is to prevent the second connecting steel strand 6 from tilting after the first movable connecting block 7 in the first installation component 4 near the bottom of the building tightens the first connecting steel strand 5.

[0040] The second-level first connecting steel strand 5, which is positioned from low to high, also requires construction workers to use a slender clamp to cooperate with the first connecting steel strand 5 to tighten it, and then install the second fixing clamp 13 after tightening. The specific installation of the second fixing clamp 13 can be achieved by construction workers standing on the edge of the parapet 1 with the help of tools. It is easy to operate and has low construction safety hazards, so that the "X"-shaped support structure of the lowest level can be stably formed. When the remaining "X"-shaped support structures are constructed, it is ensured that the second connecting steel strand 6 does not tilt.

[0041] A first fixing clamp 9 is connected to the first connecting steel strand 5 in the first installation component 4 close to the suspension component 2, and a second movable connection block 8 is connected to the first connecting steel strand 5 in the first installation component 4 farthest from the suspension component 2. A third connecting steel strand 10 is connected between the second movable connection block 8 and the first fixing clamp 9. A second installation component is formed by the first fixing clamp 10, the second movable connection block 8 and the third connecting steel strand 10. The position of the second movable connection block 8 is obtained by the fourth sensor on the second movable connection block 8. The control terminal sends a control signal to the fourth controller based on the position of the second movable connection block 8. The fourth controller controls the third drive motor 82 to start, and the third drive motor 82 drives the moving wheel 81 to move the second movable connection block 8 to a preset position. Then the fourth controller controls the third drive motor 82 to stop, so that a photovoltaic panel 3 is stably installed 4 between the first installation components of two adjacent levels.

[0042] During construction, a sensor is also required to be added to the first fixing clamp 9 , and the first fixing clamp 9 and the fourth sensor of the second movable connecting block 8 need to cooperate simultaneously to ensure that the third connecting steel strand 10 is installed vertically.

[0043] The third connecting steel strand 10 is connected to the fixed base 14, the fixed base 14 is fixed on the photovoltaic panel 3, and the photovoltaic panel 3 is adjusted to between the first mounting components 4 of the two adjacent levels. After the control terminal in the control system obtains the photovoltaic panel 3 reaching the preset position through the fifth sensor in the unit controller, the photovoltaic panel 3 is fixed between the first mounting components 4 of the two adjacent levels through the fixed base 14; Specifically, a mounting seat 141 is installed on the photovoltaic panel 3, and a fixing seat 144 is connected to the mounting seat 141 through a screw rod 142, and the mounting seat 141 and the fixing seat 144 embrace the third connecting steel strand 10, and the control lock buckle 15 is connected through a slender rod. The control terminal obtains the position of the photovoltaic panel 3 through the fifth sensor, and the installer pushes the slender rod to cooperate with the fixing seat 141 and the mounting seat 144 to embrace the third connecting steel strand 10, so that the photovoltaic panel 3 moves downward on the third connecting steel strand 10 and moves between the first mounting components 4 of the two adjacent levels. At this time, the fifth sensor obtains that the position of the photovoltaic panel 3 reaches the preset position, and the control terminal sends a control signal to the fifth controller. The fifth controller controls the drive motor 143 to work, and the drive motor 143 drives the screw rod 142 to rotate, thereby reducing the distance between the mounting seat 141 and the fixing seat 144, and tightly embraces the third connecting steel strand 10 with the mounting seat 141 and the fixing seat 144, and fixes the photovoltaic panel 3 on the third connecting steel strand 10.

[0044] The patent principle of this application: The support structure of this application itself is not connected to the building body. The control terminal uses GPS to control the movement of the corner connection block 4, the first mobile connection block 7, the second mobile connection block 8, and the second connection steel strand 6 to form a support structure. The overall construction and installation are simple and light, and will not impose excessive load on the existing building roof. At the same time, the photovoltaic panel 3 is installed or disassembled by sliding on the second vertical connection steel strand 10 by controlling the lock 15 to cooperate with the fixing seat 14, ensuring the convenience and safety of workers' operation. The installation of this application does not require any workers to work outside the building outline, which can reduce the danger of construction.
