Abstract
The utility model provides a building joint fastener which is mainly used for the connection between steel pipes when a scaffold is built. The building joint fastener is characterized in that a retainer ring is fixedly arranged around the middle part of a connecting pipe, a spring is sleeved on a bolt between an arc-shaped buckling hoop and the connecting pipe, and the building joint fastener is connected into a whole through the bolt penetrating through the arc-shaped buckling hoop, the spring and the connecting pipe. The building joint fastener has the advantages of convenience in operation, durability, easiness in manufacture and the like.
Description
Technical field
The utility model belongs to construction work facility technology field, relates to a kind of joint fastener for building.
Background technology
In fields such as building and finishings, often to scaffold erecting, existing scaffold is to be formed by connecting by the joint fastener by some steel pipes.At present, widely used joint fastener comprises the arc button hoop on tube connector, the tube connector, and steel pipe is interspersed on the tube connector and the effect by bolt on the tube connector makes arc buckle hoop to compress steel pipe.This joint fastener after two steel pipes are interspersed in tube connector, often is difficult to aim at screw when wearing bolt in actual use, and it is right repeatedly to try, and the operation easier that this has increased the operating personnel has influenced the engineering construction progress.
Summary of the invention
The inventor finds that in the daily course of work existing joint fastener exists above-mentioned defective, improves through constantly exploring, and technical problem to be solved in the utility model provides a kind of easy to operate joint fastener for building.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that the structure of this joint fastener for building comprises tube connector, two arc button hoops of tube connector top and the bottom and be interspersed in tube connector and arc button hoop on the bolt of screw, week set firmly a back-up ring on one's body at the tube connector middle part, screw on the tube connector passes back-up ring, the sheathed spring of difference on the bolt between every arc button hoop and tube connector.
The utility model adopts technique scheme that existing joint fastener is improved, a sheathed spring on the bolt between arc button hoop and tube connector, bolt is interted on tube connector always and needn't take off, steel pipe socket is connected on that the back only needs a fastening bolt to scaffold erecting on the tube connector in the use; On tube connector, establish back-up ring, can effectively prevent to be connected on steel pipe damage spring in the process of tube connector at steel pipe socket, the utlity model has easy to operate, durable, be easy to advantages such as processing and economical with materials.
Description of drawings
Fig. 1 represents the structural representation of the utility model joint fastener for building;
In Fig. 2 presentation graphs 1 along the structural representation of A-A direction.
The specific embodiment
Specify below in conjunction with the structure of the drawings and the specific embodiments the utility model joint fastener for building.
Referring to Fig. 1, Fig. 2, the structure of the utility model joint fastener for building comprises tube connector 1, be positioned at the two arc button hoops 2.1 of tube connector about in the of 1,2.2, weld a back-up ring 3 on one's body in 1 middle part week of tube connector, on arc button hoop 2.1,2.2, back-up ring 3, tube connector 1, offer screw, establish a bolt 4 in the screw, at arc button hoop 2.1,2.2 and a sheathed spring 5.1,5.2 respectively on the bolt 4 of 1 of tube connector, bolt 4 is buckled hoop 2.1 with arc, 2.2, spring 5.1,5.2, tube connector 1 be connected as a single entity by nut 6.
Bolt in the utility model joint fastener for building is buckled hoop, spring, tube connector with arc and is connected as a single entity, under normal circumstances since the effect of spring force only need loose bolts and needn't lay down bolt.When using; at the used steel pipe of tube connector two ends difference socket built; treat to tight a bolt when two steel pipes touch back-up ring; thereby arc button hoop just is pressed on the steel pipe of socket and fixes two steel pipes; because the effect of spring force; exist certain distance between arc button hoop and tube connector; steel pipe is easy to be socketed on the tube connector, so have easy to operate advantage, the effect of back-up ring can make the steel pipe of socket can not touch spring; thereby protected spring; in the application life of increase equipment, the utility model adopts steel part to make, and has strengthened its durability; and be easy to processing and fabricating, save material.
Claims (1)
1. joint fastener for building, comprise tube connector, two arc button hoops of tube connector top and the bottom and be interspersed in tube connector and arc button hoop on the bolt of screw, it is characterized in that week setting firmly a back-up ring on one's body at the tube connector middle part, screw on the tube connector passes back-up ring, the sheathed spring of difference on the bolt between every arc button hoop and tube connector.
