The disadvantages of this approach are: due to the characteristics of the building structure, the size and the depth of the reserved cavity cannot be ensured, and when the reserved cavity is small, the welding nail has a certain length and occupies the space of the cavity, so that a welding gun cannot extend into the welding nail to weld the steel plate; or when the cavity is deep, the required welding nail is longer, the welding gun cannot stretch into the welding nail, the cavity can only be broken for welding, time and labor are wasted, and the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
For solving exist among the prior art more than not enough, the utility model aims at providing a connecting device convenient to installation in narrow and small space to reach the purpose of being convenient for install connecting device, improvement work efficiency, save labour time in narrow and small space.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a connecting device convenient to installation in narrow and small space, includes first connecting piece, first connecting piece still including being used for with steel sheet fixed connection's second connecting piece including being used for the joint body of joint on the concrete, first connecting piece passes through the fixed part and can dismantle with the second connecting piece and be connected.
As to the utility model limit: the first connecting piece is a welding nail, and the clamping body is the head of the welding nail.
As a further limitation to the present invention: the second connecting piece is a nut, the nut is welded on the steel plate, the fixing portion is an external thread which is arranged on the welding nail and matched with an internal thread of the nut, and the welding nail is in threaded connection with the nut.
As a further limitation to the present invention: the second connecting piece is cylindrical, and the welding is on the steel sheet, the rod end of welding nail be equipped with second connecting piece complex recess, the fixed part is for locating the external screw thread on the second connecting piece outer wall and locating the internal thread on the welding nail recess inner wall.
Since the technical scheme is used, compared with the prior art, the utility model, the beneficial effect who gains lies in:
(1) the utility model discloses utilize the principle of lengthening, divide into two parts with connecting device, fix second connecting piece and steel sheet first, because length is shorter, be convenient for welder to stretch into the cavity of reserving, then can dismantle the connection with second connecting piece through the fixed part with first connecting piece, can fix first connecting piece to second connecting piece manually, save welder's operation, the staff installation is easily controlled, convenient operation has improved work efficiency, has saved installation time;
(2) the first connecting piece of the utility model is a welding nail, adopts a standard piece, can be directly purchased, reduces the processing cost and is convenient to use;
(3) the utility model discloses a second connecting piece adopts the nut, and when welder welded nut and steel sheet, because the nut is shorter, provided sufficient space for welder to stretch into the cavity of reserving, the welding is convenient quick, and directly adopts the standard component, and the purchase is convenient, has saved the processing cost, processes the external screw thread on the welding nail simultaneously, and is simple and convenient, and both pass through threaded connection, and the operation of being convenient for, the connection is quick, easily controls;
(4) the utility model discloses set up the recess at the rod end of welding the nail, make second connecting piece joint in the recess, both adopt screw-thread fit to connect, as long as staff rotating welding nail, can connect both, and is convenient fast, and the rate of having worked is high.
To sum up, the utility model discloses install fast convenient, work efficiency is high, the cost of manufacture is low in narrow and small space, and standardization level is high, is applicable to being connected of steel sheet and concrete among all building structure.
