Abstract
The utility model relates to a connecting pipe for reinforced bar joints, which is particularly processed and used for connecting reinforced bar joints in reinforced concrete engineering. One end of the connecting pipe forms a double-peak and double-valley shape, or is processed to be a plane end whose inner wall is provided with a concave groove, and the end is used for the processing in a plant; the other end is a plane end and is used on the spot. The utility model aims to be suitable for various connections for the reinforced bar joints in the reinforced concrete engineering and under the specific construction condition, obtaining reinforced bar butt joints with reliable quality. The quality of the reinforced bar joints can be effectively ensured through the utility model, the construction time of the reinforced bar construction on the spot can be shortened, and the cost of the reinforced concrete engineering can be reduced; simultaneously, the specific requirements of various reinforced bar engineering can be satisfied.
Description
The utility model belongs to the reinforced bar engineering technical field of construction of building and hydraulic engineering.
Reinforced concrete structure is the most widely used structure of building hydraulic engineering, and characteristics and construction needs according to engineering structures have a large amount of bar splices to connect at the construction field (site).The method of present domestic reinforced bar engineering job site spreading reinforcing bar mainly adopts arc welding and colligation overlap joint, reinforcing bar binding joint (particularly particle size reinforcing bar binding joint) stressed effect is relatively poor, arrangement of cloth muscle and concreting etc. are all made troubles, to consume steel simultaneously more, thereby improve the reinforced concrete works expense, though the reinforcing bar arc-welded joint is both economical, but because construction condition is relatively poor, the construction disturbing factor is many, therefore work efficiency is lower, often influences whole workmanship and duration thus.
The purpose of this utility model is to design one group of bar splice tube connector and comes connecting reinforcement, makes this bar splice tube connector can become reliable quality reinforcing bar banjo fixing butt jointing, shortens the reinforced bar engineering on-site construction time significantly, reduces the reinforced concrete works expense simultaneously.
The bar splice tube connector is the steel sleeve through special processing, and bar splice tube connector one end is planar end surface, and the other end is processed into the double-peak and double valley shape of symmetry; Perhaps two end faces of bar splice tube connector are planar end surface, select (comprising the reinforcing bar nominal diameter, strength grade and reinforcing bar profile) the bar splice tube connector of respective type according to engine request and reinforcing bar state to be connected.Tube connector one end is a double-peak and double valley shape, the other end is planar end surface, when steel bar end to be connected inserts tube connector double peak to valley one end, weld along the relevant place of reinforcing bar with arc welding with tube connector peak valley line, because this filler weld is symmetrically distributed on the end reinforced different cross section, it all is more rational that the performance of this end tube connector and reinforcing bar joint portion is analyzed from structural stress state and hot-working metallurgy viewpoint.Simultaneously, this end arc welding work is finished in the reinforcement yard of building site, because reinforcement yard's production welding condition is more superior than the job site, disturbing factor is few, so work efficiency than higher, also guarantees weldquality easily.Tube connector is an end of planar end surface, inside pipe wall is provided with many annular grooves, article two, symmetrical longitudinal fluting and annular groove vertical connection, also be furnished with a tapping hole and an air vent on the longitudinal fluting, this bar splice tube connector in reinforcement yard with arc welding finish joint half, second half finishes joint with the method for attachment of the molten lock of aluminothermy casting ingot at the construction field (site), forms complete reliable bar splice; Perhaps tube connector one end is a double-peak and double valley shape, in factory with arc welding finish joint half, the other end, this end tube connector inwall is provided with two symmetries, the groove that total length connects, this end is finished with the mechanical presses method of attachment at the construction field (site), forms complete reliable bar splice; Be double-peak and double valley shape perhaps at tube connector one end, in factory with arc welding finish joint half, the tube connector other end is planar end surface, this end tube connector inwall is processed into screw thread, finishes with the spiral connection method at the construction field (site), forms complete reliable bar splice; Perhaps two end faces of tube connector are planar end surface, tube connector inwall one end be provided with two grooves in factory with the mechanical presses connection method finish joint half, tube connector other end inwall is provided with many annular grooves, also have two longitudinal flutings to communicate with it, be furnished with a tapping hole and an air vent on the longitudinal fluting, this end is finished with the method for attachment of the molten lock of aluminothermy casting ingot at the construction field (site), forms complete reliable bar splice; Perhaps two end faces of tube connector are planar end surface, tube connector inwall one end is provided with two grooves, in factory with the mechanical presses connection method finish joint half, tube connector other end inwall is processed into screw thread, this end is finished with the spiral connection method at the construction field (site), forms complete reliable bar splice; Perhaps two end faces of tube connector are planar end surface tube connector inwall and are provided with the groove that two total lengths connect, tube connector one end in factory with mechanical presses connect method finish joint half, second half finishes joint with the mechanical presses method at the construction field (site), forms complete reliable bar splice.But the utility model connecting reinforcement scope is 20 millimeters to 50 millimeters of diameters.
The utility model major advantage: the specific execution conditions that can adapt to all kinds of reinforced concrete workss, and can make full use of constructor's existence conditions, use technology is simple, can guarantee effectively that bar splice becomes the reliable quality banjo fixing butt jointing, can shorten the reinforced bar engineering on-site construction time significantly, reduce the reinforced concrete works expense simultaneously.
