Abstract
The utility model discloses a reinforced bar connecting flared end sleeve. A sleeve body is of a straight tube shape or an elbow tube shape, and the end part of the sleeve is a horn mouth type flared end. The flared end is connected to one end or the both ends of the sleeve body. The flared end is provided with a crack in axial direction. The opening angle of the flared end is ranged from 0 DEG to 179 DEG. The inner wall of the sleeve body has a section or two sections of thread(s) used for connecting a reinforced bar. The flared end sleeve causes the reinforced bar to be convenient to be inserted and connected by the flared end at the end part, thereby lowering the difficulty of construction. The reinforced bar connecting flared end sleeve can solve the problem of difficult centering or difficult reinforced bar rotation occurred in the process of the connection of the reinforced bar and the sleeve. The connection with the reinforced bar can be in the threaded way, squeezing way or in the way that one end is in the straight threaded connection and the other end is in the squeezing connection.
Description
(1) technical field
The utility model relates to a kind of rebar connector in the building operations.
(2) background technology
Reinforcing steel bar connecting sleeve tube is a kind of bar splice that two reinforcing bars to be connect can be linked into an integrated entity.Traditional reinforcing steel bar connecting sleeve tube mostly is straight screw sleeve, and this type of tube-in-tube structure is comparatively simple, has advantage easy to connect, simple to operate.Yet in the construction of some special circumstances, the particularly installation of reinforcing cage must guarantee that many steel bar overall successful connections put in place, guarantees the quality of connection of sleeve.And traditional straight screw sleeve and be not suitable for reinforcing bar and be difficult to centering or reinforcing bar and rotate than situation of difficult.
(3) utility model content
The purpose of this utility model provides a kind of reinforcing bar and connects the enlarging sleeve, solve reinforcing bar with process that sleeve is connected in occur be difficult to centering or reinforcing bar rotates difficult problem.
For achieving the above object, the utility model adopts following technical scheme:
This reinforcing bar connects the enlarging sleeve, and stack shell is a cylindrical shape, it is characterized in that: sleeve ends is the bell mouth shape enlarging.
Above-mentioned enlarging is connected in the one or both ends of stack shell.
Above-mentioned enlarging is axially having the crack.
The open angle of above-mentioned enlarging is 0 °～179 °.
The inwall of above-mentioned stack shell has one section or two sections screw threads that are used for connecting reinforcement.
Above-mentioned stack shell is straight tube shape or elbow-shaped.
The barrel of above-mentioned sleeve is uniform thickness or uniform thickness not.
The stack shell of above-mentioned sleeve and the interface of enlarging are even surface or folding face.
Compared with prior art the utlity model has following characteristics and beneficial effect: this enlarging jacket tube is connected effective especially to the lower reinforcing bar of installation accuracy, can make full use of this sleeve advantage lower to construction requirement, improve the speed of construction, reduction of erection time, reduction cost, promptly can use separately, also can be used in combination in conjunction with other sleeves.The utility model is provided with enlarging by the one or both ends at stack shell to have with following advantage:
1. quick construction makes two sections reinforcing bars be convenient to penetrate connection by the enlarging of sleeve ends, has reduced the difficulty of construction.
2. high-quality, construction quality are easy to control.
3. high-speed, reduced the difficulty that the reinforcing bar butt joint is inserted, be convenient to constructor's operation, thereby be beneficial to the raising speed of application.
4. low cost, the utility model has been saved manpower, material, can save cost.
The utility model is especially suitable in the installation process of reinforcing cage.The utility model also can be widely used in other reinforcing bars and connect the occasion of difficulty in addition, has advantage easy to use, swift to operate, good connecting effect, has guaranteed construction quality.

(5) specific embodiment
Embodiment one is referring to shown in Figure 1, and this reinforcing bar connects the enlarging sleeve, and stack shell 2 is straight tube shape or elbow-shaped.Its inwall has two sections screw threads that are used for connecting reinforcement, and sleeve ends is bell mouth shape enlarging 1.Above-mentioned enlarging 1 is connected in the one or both ends of stack shell 2.Enlarging 1 open angle is generally 45 °～60 °.The inwall of stack shell 2 can have one section or two sections screw threads that are used for connecting reinforcement.During the no screw thread of stack shell 2, can be used for steel bars and connect.The utility model can be for being threaded, pushing the connection of a connection or an end straight thread, end extruding connection with being connected of reinforcing bar.Bell-mouthed shape of generatrix can be linear, camber line or shaped form.
Embodiment two is referring to shown in Figure 2, and different with embodiment one is that enlarging 1 is axially having crack 3.
Embodiment three is referring to shown in Figure 3, and different with embodiment one is the two ends that enlarging 1 is positioned at stack shell.
Embodiment four is referring to shown in Figure 4, and the two ends of different with embodiment one is stack shell all have enlarging 1, two enlarging all to have the crack.
The embodiment Wucan is seen shown in Figure 5, and all there is enlarging 1 at the two ends of different with embodiment one is stack shell, and wherein the enlarging of an end has the crack.
Insert for ease of reinforcing bar, the junction of the inwall of enlarging, enlarging and stack shell is for being connected smoothly or non-being connected smoothly, and the crack in the enlarging can be divided into enlarging some lobes, and the shape in crack can be V-arrangement, U-shaped, trapezoidal or arbitrary shape.Enlarging 1 can be positioned at the one or both ends of stack shell.Enlarging and stack shell are same metal material, also can be different materials.Enlarging can with stack shell equal thickness, also equal thickness not.Barrel can be an equal thickness, also can be equal thickness not.
The course of work of the present utility model: check the supporting whether suitable of reinforcing bar and sleeve earlier, and try cover; Make telltale mark at steel bar end; By the reinforcing bar telltale mark reinforcing bar is inserted sleeve inner by enlarging; With extrusion equipment with reinforcing bar and the crimping of enlarging sleeve, can be by the enlarging sleeve once with two reinforcing bar crimping, also can be, and then insert another root and connect reinforcing bar, extruding other end sleeve in advance with enlarging sleeve and a reinforcing bar crimping.
