Specific embodiment

The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made. These are all within the protection scope of the present invention.

In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure or Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaning Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

As shown in Figure 1 to Figure 3, building lightning conduction lightning protection device provided by the utility model comprising fastener structure, connects sudden strain of a muscle Device 1 and ground connections 2；Accommodating chamber 3 is provided in the fastener structure, accommodating chamber 3 extends along fastener structure length direction, The arrester 1 is on length extending direction through the corresponding accommodating chamber 3 of one or more fastener structures；The fastener structure exists Two end faces on thickness extending direction are respectively formed first end face 5, second end face 6；The ground connections 2 are mounted on second On end face 6, it can be contacted with ground connections 2 when arrester 1 is mounted in accommodating chamber 3；One is equipped in single fastener structure A or multiple ground connections 2；3 inner space of accommodating chamber forms accommodation space, and the accommodation space is by being arranged in first end Connecing on face 5 gets out of the way slot 4 and exterior space is interconnected.Preferably, the arrester 1 includes lightning conduction band steel.

Preferably, the width of the accommodating chamber 3, which is greater than, connects the groove width for geing out of the way slot 4；In the projection of fastener feature cross-section, fastener Structure gets out of the way the two side portions in the width direction of slot 4 and forms wing plate portion 9 connecing.The setting in wing plate portion 9, on the one hand, can will connect Dodge device 1 be limited in accommodating chamber 3, prevent arrester 1 along connect get out of the way slot 4 deviate from.Correspondingly, 1 width of arrester is greater than to connect and get out of the way The groove width of slot 4.But in practical applications, it is not limited to above-mentioned size limitation, for example, the width of accommodating chamber 3 can be with Equal to or less than connecing the groove width for geing out of the way slot 4；For another example 1 width of arrester, which is equal to or less than, connects the groove width for geing out of the way slot 4, this Allow during installation arrester 1 directly get out of the way slot 4 and penetrate into accommodating chamber 3 from connecing, operate it is more convenient, the disadvantage is that needing The additional situation for considering arrester 1 and tilting.

It include the first fastener 7 and/or the second fastener 8 in multiple fastener structures；The height of accommodating chamber 3 in first fastener 7 More than or equal to the height of accommodating chamber 3 in the second fastener 8.As shown in Figure 1, it is contemplated that practical building structure, the first fastener 7, Two fasteners 8 are respectively arranged on parapet I, building column II, wherein the second fastener 8 is embedded in building column, it only need to be by arrester 1 It is formed directly into, therefore 3 height of corresponding accommodating chamber can be smaller.As shown in figure 5, in the wing plate portion 9 of first fastener 7 It is provided with bolt hole 10, arrester 1 is pressed on the bottom of accommodating chamber 3 by the hold-down bolt 11 being arranged in bolt hole 10.It is preferred that Ground, the shape of the bolt hole 10 is round or with strip, passes through the setting of the bolt hole 10 of strip, on the one hand, is compressed The position of bolt 11 can be adjusted, and be able to carry out adaptation to installation error；On the other hand, 1 heat expansion of arrester also can effectively be adapted to The variation of length caused by shrinkage.Preferably, connecing for the first fastener 7 gets out of the way the groove width of slot 4 and dodges slot less than connecing for the second fastener 8 Groove width, that is to say, that the width in the wing plate portion 9 of the first fastener 7 needs appropriate increase, to provide the installation position of hold-down bolt 11 It sets.

Preferably, the corresponding ground connections 2 of the second fastener 8 are Y shape, and the corresponding ground connections 2 of the first fastener 7 are Strip.Preferably, butt hole is provided in the second end face 6；The ground connections 2 are inserted into butt hole, and are led to The screw for crossing setting is fastenedly connected with fastener.Preferably, 2 cross section of ground connections is rectangle or circle；Grounding connection Part 2 extends up in accommodation space, and multiple screws are distributed in ground connections 2 along the two sides of width extending direction or radially prolong Stretch the two sides in direction.

In practical application, arrester 1 is clamped (the pre-buried fixation on roofing or parapet of laying installation mode using built-in type Fastener connect with main reinforcement in column when fastener structure is pre-buried and makees down conductor, and fastener structure and arrester 1 using clamping or add spiral shell Bolt is fixed, and part fastener is with slidably bolt, to prevent the variation that arrester expands with heat and contract with cold and generates).

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment Sign can be arbitrarily combined with each other.
