Abstract
The utility model relates to a fast connection device of grounded round steels. The fast connection device is characterized by comprising a connecting piece made of a conducting material, wherein at least two hollow branch pipes are arranged on the connecting piece; each hollow branch pipe is provided with an outer thread outside the whole pipe wall or a part of the pipe wall close to the pipe opening, and a fastening nut which is correspondingly matched and connected with the outer thread of each hollow branch pipe is also sleeved on the pipe wall of each hollow branch pipe; and the pipe wall of each hollow branch pipe, which is close to the pipe opening, is formed by a plurality of dovetail-shaped clamping pieces at different circumferential positions, and the inward gradient of the outer wall of each dovetail-shaped clamping piece from the pipe opening along the axial direction is gradually reduced. According to the fast connection device disclosed by the utility model, more than two grounded round steels can be rapidly and adjacently connected, so that the fast connection device has the advantages of rapid, simple and convenient construction, high construction quality and reliable connection.
Description
Technical field
The utility model relates to a kind of Quick Connect Kit of ground connection round steel.
Background technology
The grounding system firm and reliable connection is the emphasis that guarantees the electrical engineering safety function; The ground connection of wire casing, crane span structure and the zinc-plated ground connection round steel of lightning-arrest a large amount of employings lay along support in the architectural engineering; The connection of traditional zinc-plated ground connection round steel all is to adopt electric welding to connect; Not only take a lot of work, time-consuming, operational sequence is numerous and diverse, and construction back quality is not good.Major defect is following:
(1) adopt electric welding to connect, must electric welding machine be lifted and carry off, labor is artificial.
(2) according to code requirement, should adopt two-sided welding, weld length should reach the diameter of 6 times of ground connection round steel.But on-the-spot major part is welded on furred ceiling inside, and overhead welding is adopted in welding, operation inconvenience, and welding quality is too poor.
(3) welding is accomplished and must welding slag be knocked out, and the brush antirust paint is treated to brush aluminium paint again after paint is done, and operation is many, complicated operation.
(4) adopt welding, because the reason of expanding with heat and contract with cold, round steel meeting flexural deformation causes impression relatively poor.
(5) adopt welding, must cut off round steel, troublesome poeration when removing the ground connection round steel.
Summary of the invention
The purpose of the utility model is to provide a kind of Quick Connect Kit of ground connection round steel, and it can make two quick adjacent connections of above ground connection round steel, and not only quick construction is easy, and construction quality is high, connects reliable.
The purpose of the utility model realizes through following technical scheme: a kind of Quick Connect Kit of ground connection round steel is characterized in that: it comprises the connector of being processed by electric conducting material, and said connector is provided with at least two hollow arms; Each hollow arm all or outside the tube wall near mouth of pipe place is provided with external screw thread at it, and the tube wall of each hollow arm also is equipped with the clamp nut that is connected with the external screw thread corresponding matching of each hollow arm outward; Each hollow arm is made up of a plurality of dovetail shaped intermediate plates that are distributed in different circumferential positions near the tube wall at mouth of pipe place, and the outer wall of each dovetail shaped intermediate plate plays the inside vertically gradient by the mouth of pipe and reduces gradually.
The further improvement of the utility model technique scheme is: each hollow arm all or in the tube wall near mouth of pipe place is provided with internal thread at it.
The operation principle of the utility model is explained as follows: during use; Only need each ground connection round steel of adjacent connection be inserted respectively in each hollow arm and put in place; Each clamp nut is screwed to the mouth of pipe place of corresponding hollow arm respectively because the dovetail shaped intermediate plate has the suitable gradient, therefore at clamp nut in the process that the mouth of pipe moves; Each dovetail shaped intermediate plate shrinks to the tube hub direction; Clamp the ground connection round steel, make the ground connection round steel realize that with corresponding hollow arm solid and reliable conduction is connected, the solid and reliable conduction of realization connects between the adjacent ground connection round steel thereby make.When each hollow arm at it all or when also being provided with internal thread near the tube wall at mouth of pipe place, in the effect of screwing of clamp nut down, the dependence internal thread can be extracted the screw thread screw thread with ground connection round steel appearance, reaches the reliable ground connection interconnect function of further realization.
Compared to prior art, the utlity model has following advantage:
(1) simple to operate, only need a workman to be with a spanner to accomplish, need not electric welding machine, equipment such as cutting machine.
(2) convenient and quick construction has only one procedure, can improve work efficiency greatly, and accelerating construction progress in labour cost surging today, has good economic benefit and social benefit.
(3) can not cause the distortion of ground connection round steel after the construction, improve construction quality greatly.
(4) not only simple in structure, easy to process, production cost is low, and easy accessibility, can second use.

Embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
The embodiment 1 and embodiment 2 organigrams of the Quick Connect Kit of a kind of ground connection round steel that provides for the utility model as depicted in figs. 1 and 2; It is characterized in that: it comprises the connector of being processed by electric conducting material, and said connector is provided with at least two hollow arm 1-1; Each hollow arm 1-1 all or outside the tube wall near mouth of pipe place is provided with external screw thread 1-2 at it, and the tube wall of each hollow arm 1-1 also is equipped with the clamp nut 1-3 that is connected with the external screw thread 1-2 corresponding matching of each hollow arm 1-1 outward; Each hollow arm 1-1 is made up of a plurality of dovetail shaped intermediate plate 1-4 that are distributed in different circumferential positions near the tube wall at mouth of pipe place, and the outer wall of each dovetail shaped intermediate plate 1-4 plays the inside vertically gradient by the mouth of pipe and reduces gradually.
Each hollow arm 1-1 all or in the tube wall near mouth of pipe place is provided with internal thread at it.
