The utility model relates to a steel bar connection device for construction, setting through two carousels in the sleeve, two barrels can the free rotation, consequently only need to twist respectively and move two barrels and can be connected to together the link of two reinforcing bars through this device, need not hard twisting the reinforcing bar, and through the setting of screw thread section of thick bamboo, barrel outside screw thread section of thick bamboo can play the fulcrum effect, it is convenient when consequently twisting the barrel, and through the setting of observing the hole, can observe the reinforcing bar that stretches into in the barrel and have or not twist to target in place through observing the hole, and then ensure two steel bar connection's stability, can screw up the locking bolt at last and further fix the reinforcing bar fastening of spiro union to the barrel, thereby effectually prevent that the reinforcing bar from receiving external force and rotating and break away from in the barrel.
Description
Technical Field
The utility model relates to a construction field, concretely relates to steel bar connection device for construction.
Background
The steel bar connecting sleeve connection is a steel bar connecting technology commonly used in large-scale building engineering in the building industry, and when the steel bars are connected, the steel bar connecting sleeve is used for connecting the two steel bars together in a threaded or radial segmented extrusion connection mode, so that the steel bar connecting sleeve has the advantages of simplicity and rapidness in operation, raw material saving, stable quality, no limitation of steel bar components and the like. However, the existing steel bar connecting sleeve connection still has great defects, the existing steel bar connecting sleeve is composed of a cylinder body, the direction of flat cutting threads is consistent, when two steel bars are connected in a threaded mode, one steel bar needs to be screwed into the steel bar connecting sleeve, the length of the steel bar is hard to screw the steel bar, the outer portion of the existing steel bar connecting sleeve is a smooth surface, a fulcrum is lacked, the hard to screw the steel bar connecting sleeve is hard to screw, meanwhile, the existing steel bar connecting sleeve cannot accurately estimate the length of the steel bar extending into the sleeve, so that a novice or careless worker cannot determine the length of the two steel bars extending into the steel bar connecting sleeve, the connection is unstable, the later-stage house safety is seriously affected, and the existing steel bar connecting sleeve is not provided with a fastening bolt, so that the steel bar is easy to rotate to be separated from the connecting sleeve under the action of external force, therefore, a new reinforcing bar coupler is urgently needed to solve the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problem, the utility model provides a steel bar connection device for construction.
The utility model discloses a realize through following technical scheme:
the utility model provides a steel bar connection device for construction, includes the sleeve, the sleeve internal rotation is equipped with two carousels, and two carousels laminate with sleeve both sides inner wall respectively, the sleeve both sides symmetry laminating respectively has the barrel, and two barrel relative lateral wall central authorities department are fixed with the pivot respectively, and two relative one ends of pivot pierce through the sleeve both sides respectively and go deep into its inside and two carousel lateral wall fixed connection, pivot and sleeve contact department swivelling joint, the barrel top is close to sleeve one side department and has seted up the observation hole, barrel bottom central authorities department is fixed with a screw thread section of thick bamboo, a screw thread section of thick bamboo and the inside intercommunication of barrel, the spiro union has locking bolt in the screw thread section of thick bamboo, set up the internal thread.
Preferably, the length of the cylinder is 4-6 cm.
Preferably, the barrel body is fixedly connected with the threaded barrel through welding.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a steel bar connection device for construction, setting through two carousels in the sleeve, two barrels can the free rotation, consequently only need to twist respectively and move two barrels and can be connected to together the link of two reinforcing bars through this device, need not hard twisting the reinforcing bar, and through the setting of screw thread section of thick bamboo, barrel outside screw thread section of thick bamboo can play the fulcrum effect, it is convenient when consequently twisting the barrel, and through the setting of observing the hole, can observe the reinforcing bar that stretches into in the barrel and have or not twist to target in place through observing the hole, and then ensure two steel bar connection's stability, can screw up the locking bolt at last and further fix the reinforcing bar fastening of spiro union to the barrel, thereby effectually prevent that the reinforcing bar from receiving external force and rotating and break away from in the barrel.
Drawings
Fig. 1 is a structural diagram of the structure of the present invention.
In the figure: sleeve 1, carousel 2, pivot 3, barrel 4, observation hole 5, a screw thread section of thick bamboo 6, locking bolt 7.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, a steel bar connection device for building construction, includes sleeve 1, its characterized in that: 1 internal rotation of sleeve is equipped with two carousels 2, and two carousels 2 laminate with 1 both sides inner wall of sleeve respectively, the laminating of 1 both sides of sleeve symmetry respectively has barrel 4, and two 4 relative lateral wall central authorities of barrel locate to be fixed with pivot 3 respectively, and two 3 relative one ends of pivot pierce through 1 both sides of sleeve respectively and go deep into its inside and two 2 lateral walls of carousel fixed connection, pivot 3 and 1 contact department swivelling joint of sleeve, 4 top of barrel are close to 1 one side department of sleeve and have seted up observation hole 5, 4 bottom central authorities of barrel department are fixed with a screw thread section of thick bamboo 6, a screw thread section of thick bamboo 6 and the inside intercommunication of barrel 4, the spiro union has locking bolt 7 in a screw thread section of thick bamboo 6, set up the.
The length of the cylinder body 4 is 4-6 cm.
The barrel body 4 and the threaded barrel 6 are fixedly connected by welding.
The working principle is as follows: the utility model discloses when using, because the setting of two carousel 2 in the sleeve 1, two barrel 4 can the free rotation, consequently only need to twist respectively and move two barrel 4 can be connected to the link of two reinforcing bars together through this device, need not hard twisting the reinforcing bar, and through the setting of screw thread section of thick bamboo 6, barrel 4 outside screw thread section of thick bamboo 6 can play the fulcrum effect, it is convenient when consequently twisting barrel 4, and through the setting of observing hole 5, can observe the reinforcing bar that stretches into in the barrel 4 and have or not twist in place through observing hole 5, and then ensure two steel bar connection's stability, can twist locking bolt 7 at last and further fix the reinforcing bar fastening of spiro union to barrel 4, thereby effectually prevent that the reinforcing bar from breaking away from in barrel 4 because of receiving external force and rotating.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
