Description
Technical Field
[0001] This application relates to the technical field of lightning protection and grounding construction for building engineering roofs, and particularly to a post-installed lightning protection and grounding bracket for parapets on the roof. Background Art
[0002] In the field of building construction, round steel is mostly used for cross-connection in the construction of lightning protection down conductors and grounding grids to ensure the connection of the entire lightning protection and grounding system. Before construction, the cross-connection round steel needs to be cut in advance and then connected into one body. A firm and reliable connection of the grounding system is the key to ensuring the safety function of electrical engineering. In building engineering, a large number of lightning protection devices use grounding round steel laid along the brackets.
[0003] Reliable lightning protection and grounding is an important guarantee for the safe use of buildings. Traditional lightning protection and grounding brackets need to be installed inside the parapet structure. When the surface of the parapet structure is decorated with aluminum plates or stone materials, the brackets pass through the decorative materials. Often due to temperature deformation, cracks occur at the interface between the brackets and the decorative materials, causing leakage. At the same time, the brackets pass through the decorative materials, and it is difficult to ensure that the brackets are evenly distributed on the surface of the decorative blocks, affecting the appearance. Summary of the Invention
[0004] This application provides a post-installed lightning protection and grounding bracket for parapets on the roof. The post-installed method is adopted, without punching and damaging the decorative surface, and the installation method is simple and the firmness is reliable.
[0005] This application provides a post-installed lightning protection and grounding bracket for parapets on the roof, including two split L-shaped frames. The bottom of each L-shaped frame has a support plane part adhesively connected to the parapet decorative layer; each L-shaped frame has a vertical part perpendicular to the support plane part;
[0006] Above the vertical part, there is a positioning part, and the two positioning parts cooperate with each other to form a positioning circular cavity for clamping and fixing the lightning protection and grounding round steel; among them,
[0007] The two L-shaped frames are detachably and fixedly connected by a plurality of bolt assemblies.
[0008] In this application, split L-shaped frames are used for combined fixation. The installation method is simple, without damaging the surface layer of the decorative surface, and the occurrence of leakage is suppressed; the clamping and fixing method is used to position the lightning protection and grounding round steel, providing convenience for post-assembly; at the same time, by bonding to the surface of the decorative layer of the aluminum plate or stone plate, the firmness performance is reliable; the post-installed method improves the installation efficiency of the lightning protection and grounding process, and the overall safety and stability performance is reliable.
[0009] In a specific feasible implementation, the two L-shaped frames are connected back to back. The two L-shaped frames are reasonably distributed, increasing the bonding contact surface with the decorative layer and improving the stability.
[0010] In a specific feasible implementation, the sum of the lengths of the two support plane parts ≥ 100 mm. The support plane parts are adhesively connected to the surface layer of the decorative surface (aluminum plate or stone plate) through weather-resistant structural adhesive, and the surface layer of the decorative surface is not damaged by drilling, so there is no leakage risk. At the same time, compared with the existing installation methods of drilling or embedding, the adhesive connection with a larger contact surface can greatly improve the construction efficiency and thus reduce the construction cost.
[0011] In a specific feasible implementation, the two vertical parts are at least adhesively connected and fixed through two bolt assemblies arranged along the height direction. By using at least two bolt assemblies for connection, the two vertical parts are closely attached to each other, and the firm performance of the supporting lightning protection grounding round steel is reliable.
[0012] In a specific feasible implementation, each positioning part is an arc bend, and the two positioning parts are mirror images of each other to form the positioning circular cavity. The formed positioning circular cavity can clamp and fix the lightning protection grounding round steel, so as to ensure a good positioning effect and the post-installation method is simple.
[0013] In a specific feasible implementation, the diameter of the positioning circular cavity is smaller than the diameter of the lightning protection grounding round steel. The diameter of the positioning circular cavity is 3 mm to 5 mm smaller than the diameter of the lightning protection grounding round steel, so as to tightly clamp and fix the lightning protection grounding round steel through the two L-shaped frames in a mutually embracing state with ductile deformation.
[0014] In a specific feasible implementation, a closing part is arranged at the top of each positioning part, and the two closing parts are at least adhesively connected and fixed through one bolt assembly. The method of closing at the top can further realize the tight clamping and fixing of the lightning protection grounding round steel and improve the installation stability of the lightning protection grounding round steel.
[0015] In a specific feasible implementation, each L-shaped frame is integrally bent from a plate body made of stainless steel with a thickness greater than 3 mm and a width greater than 40 mm. Using the plate body made of stainless steel as the L-shaped frame can extend the service life and has the effect of ductile deformation. While ensuring the overall fitting tightness, it improves the fixing effect on the lightning protection grounding round steel.
[0016] In a specific feasible implementation, the height of each L-shaped frame ≥ 150 mm. The overall height is the same, meeting the construction requirements and having installation unity.
[0017] In a specific feasible implementation, the multiple bolt assemblies are all stainless steel bolts with a diameter of 8 mm. It enhances the connection effect and is durable. Description of the Drawings

[0024] To facilitate the understanding of the post-mounted lightning protection and grounding bracket for the parapet wall on the roof provided by the embodiments of the present application, first, its application scenario will be described. In the field of building construction, round steel is mostly used for cross-connection during the construction of lightning protection down conductors and grounding grids to ensure the connection of the entire lightning protection and grounding system. Before construction, the cross-connection round steel needs to be cut in advance and then connected into one body. The firm and reliable connection of the grounding system is the key to ensuring the safety function of electrical engineering. In building projects, a large number of lightning protection uses grounding round steel laid along the brackets. Reliable lightning protection and grounding are important guarantees for the safe use of buildings. Traditional lightning protection and grounding brackets need to be installed inside the parapet wall structure. When the surface of the parapet wall structure is decorated with aluminum plates or stones, the brackets pass through the decorative materials. Often due to temperature deformation, cracks are generated at the interface between the brackets and the decorative materials, causing leakage. At the same time, the brackets pass through the decorative materials, and it is difficult to ensure that the brackets are evenly distributed on the surface of the decorative blocks, affecting the aesthetics. In view of this, a post-mounted lightning protection and grounding bracket for the parapet wall on the roof provided by the present application adopts a post-mounted installation method, without punching and damaging the decorative surface, and the installation method is simple and the firmness is reliable.
[0025] As shown in the reference Figure 1 In the figure, the post-mounted lightning protection and grounding bracket for the parapet wall on the roof provided by the embodiments of the present application includes two split L-shaped frames. In the present application, the post-mounted lightning protection and grounding bracket is prepared by the method of factory prefabrication. The brackets of the same batch have two L-shaped frames with the same size, so as to improve the interchangeability performance, so that any two L-shaped frames can be combined with each other to form a bracket for supporting and fixing the lightning protection and grounding round steel 80.
[0026] In a specific embodiment of the present application, each L-shaped frame is integrally bent from a plate body made of stainless steel with a thickness of 3 mm and a width of 40 mm. Using the plate body made of stainless steel as the L-shaped frame can extend the service life, and has the effect of ductile deformation, ensuring the overall fitting tightness while improving the fixing effect on the lightning protection and grounding round steel 80. As can be seen from the combination Figure 2 In the figure, each L-shaped frame has a width of at least 40 mm, so that after integral bending, a larger contact surface with the decorative layer is formed, without damaging the overall surface effect of the decorative surface, avoiding the leakage risk caused by the cracks caused by punching, and enhancing the aesthetics, further improving the construction effect.
[0027] When specifically combining two L-shaped frames into a bracket for supporting the lightning protection and grounding round steel 80, the two L-shaped frames are the first L-shaped frame 10 and the second L-shaped frame 20 respectively. The first L-shaped frame 10 and the second L-shaped frame 20 are connected in a back-to-back manner, and the first L-shaped frame 10 and the second L-shaped frame 20 are connected into an integral bracket by a plurality of bolt assemblies.
[0028] The bottoms of the first L-shaped frame body 10 and the second L-shaped frame body 20 both have a support plane part adhesively connected to the parapet decorative layer, and the sum of the lengths of the two support plane parts is ≥ 100 mm. The support plane part is adhesively connected to the surface layer of the decorative surface (aluminum plate or stone plate) through weather-resistant structural glue, and the surface layer of the decorative surface is not damaged by drilling, so there is no leakage risk. At the same time, compared with the existing installation methods of drilling or embedding, the adhesive connection with a larger contact surface can greatly improve the construction efficiency and thus reduce the construction cost.
[0029] Exemplarily, when the lengths of the two support plane parts are equal to 100 mm, the support plane part of the first L-shaped frame body 10 is 50 mm, and the support plane part of the second L-shaped frame body 20 is 50 mm, and the support plane parts of the first L-shaped frame body 10 and the second L-shaped frame body 20 are both greater than 40 mm, so that the two support plane parts have a larger bonding area with the decorative layer, and the firmness is more reliable when using weather-resistant structural glue for bonding. Of course, in other embodiments of the present application, when the lengths of the two support plane parts are equal to 120 mm, the support plane part of the first L-shaped frame body 10 is 60 mm, and the support plane part of the second L-shaped frame body 20 is 60 mm; the lengths of the two support plane parts can be cut into plate bodies of different lengths according to actual construction requirements and bent, which will not be elaborated here.
[0030] Continue to refer to Figure 1 , when supporting and fixing the lightning protection grounding round steel 80, both the first L-shaped frame body 10 and the second L-shaped frame body 20 have vertical parts 50 perpendicular to the corresponding support plane parts; at least two bolt assemblies arranged along the height direction are used to fit and connect and fix between the two vertical parts 50. Using at least two bolt assemblies for connection makes the two vertical parts 50 fit tightly, and the firmness of supporting the lightning protection grounding round steel 80 is reliable. Specifically, the two vertical parts 50 support the lightning protection grounding round steel 80 in a state of being mutually attached. At the same time, when the two vertical parts 50 face away from each other, in the present application, at least two through holes are correspondingly opened in the two vertical parts 50 along the height direction, and at least two first bolt assemblies 30 are used to pass through the through holes one by one to achieve a tightly fitting fixation. Both of the two first bolt assemblies 30 are made of stainless steel bolts with a diameter of 8 mm. It enhances the connection effect and is durable.
[0031] When clamping and fixing the lightning protection grounding round steel 80, a positioning part 60 is provided on each vertical part 50 in the present application, and the two positioning parts 60 cooperate with each other to form a positioning circular cavity for clamping and fixing the lightning protection grounding round steel 80; each positioning part 60 is an arc bend, and the two positioning parts 60 are mirror images of each other to form a positioning circular cavity. The formed positioning circular cavity can clamp and fix the lightning protection grounding round steel 80, so as to ensure a good positioning effect and the post-installation method is simple.
[0032] The diameter of the positioning circular cavity is smaller than the diameter of the lightning protection grounding round steel 80. The diameter of the positioning circular cavity is 3 mm to 5 mm smaller than the diameter of the lightning protection grounding round steel 80, so that the lightning protection grounding round steel 80 can be tightly clamped and fixed by two L-shaped frames in a mutually clamped state with ductile deformation.
[0033] At the top of each positioning portion 60, a closing portion 70 is provided, and at least one bolt assembly is used to fit and connect and fix between the two closing portions 70. The method of closing at the top can further realize the tight clamping and fixing of the lightning protection grounding round steel 80 and improve the installation stability of the lightning protection grounding round steel 80. A through hole is also opened in the closing portion 70, and a second bolt assembly 40 passes through the through hole to fit and fix the two closing portions 70, so that the diameter of the positioning circular cavity becomes smaller, and the lightning protection grounding round steel 80 is tightly clamped and fixed. The second bolt assembly 40 also uses a stainless steel bolt with a diameter of 8 mm. It enhances the connection effect and is durable.
[0034] In addition, in a specific embodiment of the present application, the height of each L-shaped frame is 150 mm. The overall height is the same, meeting the construction requirements. The stainless steel plates of the same size are sheared, and the L-shaped brackets of the same model are integrally prepared, with unity in installation and interchangeability.
[0035] In the present application, the split L-shaped frames are used for combined fixing, the installation method is simple, the surface layer of the decorative surface is not damaged, and the occurrence of leakage is suppressed; the lightning protection grounding round steel 80 is positioned by a clamping and fixing method, providing convenience for post-assembly; at the same time, it is firmly bonded to the surface of the decorative layer of the aluminum plate or stone plate, and the firmness performance is reliable; the post-installation method improves the installation efficiency of the lightning protection grounding process, and the overall safety and stability performance are reliable.
