Description

Technical Field

[0001] The utility model belongs to the technical field of roofing lightning protection treatment, and particularly relates to a lightning protection structure for metal pipes on the roof. Background Technique

[0002] The metal pipe extending out of the roof refers to the situation where a metal pipe passes through the roof from the inside of the building and extends to the outside. For example, metal pipes such as ventilation pipes, exhaust pipes, and hot water pipes of solar water heaters in the building need to pass through the roof to reach the outdoor space in order to achieve their specific functions.

[0003] In architectural design and construction, the part of the metal pipe extending out of the roof needs to be treated. When dealing with lightning protection, generally, a metal lead is welded to the metal pipe, and then the other end is welded to the surface of the embedded grounding metal part. Since the position of the metal pipe may be adjusted or changed according to requirements during the installation of the metal pipe, after the adjustment, the installer also needs to measure the distance of the metal lead, then cut it off, and finally weld it. This method is relatively inconvenient to adjust, and the connection distance also needs to be measured during installation. Therefore, we propose a lightning protection structure for metal pipes on the roof that can adjust the spacing to solve the above-mentioned deficiencies. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lightning protection structure for metal pipes on the roof, which has the purpose of facilitating the adjustment of the connection spacing to solve the above-mentioned background technical problems.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A lightning protection structure for metal pipes on the roof includes a lightning attracting column embedded in the roof. A connecting column is welded to the front surface of the lightning attracting column. The front surface of the connecting column penetrates through the roof and extends to the outside of the roof, and is sleeved with a connecting cap and fixedly connected by a bolt one. A connecting piece one is fixedly connected to the side of the connecting cap away from the connecting column. A connecting piece two is slidably arranged on the surface of the connecting piece one. A connecting seat is fixedly connected to one side of the front surface of the connecting piece two. A metal pipe body is penetrated through the inside of the roof. A block is welded to the side of the metal pipe body close to the connecting seat. A threaded cylinder is fixedly connected to the side of the block away from the metal pipe body. A bolt two is threadedly connected to the inner surface of the threaded cylinder. The bolt two penetrates through the connecting seat and extends to one side of the connecting seat.

[0006] Preferably, guide seats are welded to both the top and bottom of the surface of the connecting piece one, and the inner cavity of the connecting piece two is a cavity.

[0007] Preferably, a guide cavity adapted to slide with the guide seat is formed in the inner cavity of the connecting piece two, and the inner surface of the guide cavity is slidably connected to the outer surface of the guide seat.

[0008] Preferably, a through hole with a caliber matching that of the metal pipe body is opened inside the roof, and a water stop ring is pre-buried with cement on the outer end surface of the through hole.

[0009] Preferably, a water stop ring is sleeved on the outer surface of the metal tube body, and the outer ring of the water stop ring fits tightly with the inner surface of the water stop ring.

[0010] Preferably, a cover is threadedly connected to the surface of the metal tube body, and the cover is vertical or obliquely downward.

[0011] The beneficial effects of the utility model are:

[0012] The utility model sets the connection cap on the surface of the connection column, and then fixes the connection cap and the front face of the connection column by bolt 1, and then adjusts the connection piece 1 and the connection piece 2 according to the spacing between the metal tube body and the connection column, so that the connection piece 2 slides on the surface of the connection piece 1, and stops sliding after sliding to an appropriate distance, and the threaded barrel connected to the block body is threadedly connected by bolt 2 penetrating the connection seat, so as to facilitate the adjustment of the connection spacing, and replaces the method of measuring and cutting metal parts for welding after the position adjustment, thereby increasing the convenience of installation;

Embodiment

[0024] Figures 1-3The lightning protection structure of the roof metal pipe according to an embodiment of the present utility model is shown, which includes a lightning attracting column 2 embedded in the roof 1. A connecting column 3 is welded to the front surface of the lightning attracting column 2. The front surface of the connecting column 3 penetrates through the roof 1 and extends to the outside of the roof 1, and a connecting cap 5 is sleeved thereon, and is fixedly connected by a bolt 4. A connecting member 6 is fixedly connected to the side of the connecting cap 5 away from the connecting column 3. A connecting member 7 is slidably arranged on the surface of the connecting member 6.

A cover 17 is threadedly connected to the surface of the metal pipe body 9. The shape of the cover 17 is designed to be vertical or inclined downward. By setting the shape of the cover 17 to be vertical or inclined downward, rainwater is prevented from pouring into the metal pipe body 9.

[0025] Working principle: When the present utility model is in use, the block 10 is welded to the surface of the metal pipe body 9 in advance, and then the metal pipe body 9 penetrates through the roof 1 and extends to the outside. By setting the inner surface of the water stop ring 15 to be closely attached to the outer ring of the water stop ring 16, rainwater leakage in the through hole opened in the roof 1 can be avoided, thereby reducing the occurrence of oxidation corrosion between the metal pipe body 9 and the roof 1.
