Abstract
The utility model relates to accessories applied to building materials, and particularly relates to a reinforcing steel bar butt fixing device. The reinforcing steel bar butt fixing device comprises a connection seat and a connection cap, wherein the connection seat is in a cylindrical shape; a penetrating hole is formed in the center axis of the connection seat; threads are arranged at two ends of the connection seat; a step hole is formed inside the connection cap; a thread is arranged on the wall of the step hole; the end with a large aperture is matched with the thread of the connection seat; the end with a small aperture is connected with a reinforcing steel bar with a thread; a baffle edge is arranged in the middle of the penetrating hole. The reinforcing steel bar butt fixing device has the advantage that two reinforcing steel bars can be quickly and conveniently butted when not rotating.
Description
technical field:
The utility model relates to reinforcing bar connection area, relates in particular to steel reinforcement abutting joints fastening devices.
background technology:
Along with the development of builing industry, amount of reinforcement constantly increases, and reinforcing bar density is increasing, and the docking mode of reinforcing bar has become one of key of structure design and construction, and it directly has influence on construction project quality, speed of application, economic benefit and working security.In the construction of tunnel lining reinforcement installation, the main method that reinforcing bar connects has colligation, welding.Due to taking time and effort of colligation, and quality can not be guaranteed, seldom use the method, if the narrow region operation in space, welding job is limited by very large, and cause weld job efficiency low, and power supply for construction amount is large, to welding, operating personnel requires highly, easily causes security incident.
utility model content:
The purpose of this utility model is: a kind of steel reinforcement abutting joints fastening devices that reinforcing bar is easy to connect and be connected firmly that makes is provided.
In order to achieve the above object, the scheme that the utility model provides is: steel reinforcement abutting joints fastening devices, comprise Connection Block and attachment cap, described Connection Block is cylindric, and Connection Block central axis is provided with through hole, described Connection Block two ends are provided with screw thread, described attachment cap inside is provided with shoulder hole, and described ladder hole wall is provided with screw thread, and the larger end in described aperture mates with the screw thread of Connection Block, aperture is connected with threaded reinforcing bar compared with small end, and the centre of described through hole is provided with gear edge.
By the end reinforced one section of screw thread that arranges to be connected, because the reinforcing bar of having buried underground in building operations cannot rotate, attachment cap is enclosed within screw thread steel section compared with aperture one end, again reinforcing bar is inserted in the through hole of Connection Block, by being rotationally connected cap, make being threaded of attachment cap and Connection Block, another joining section reinforcing bar is also fastening by the way; The utility model has the advantage of: because reinforcing bar cannot rotate, make reinforcing bar be connected fasteningly not needing can realize the in the situation that of rotation by the connection of attachment cap and Connection Block, reinforcing bar rapid-aligning can be effectively realized on the gear edge arranging in the middle of through hole.
Further, in order to increase the bending resistance that is connected reinforcing bar, the length of described Connection Block is at least 20cm, and making like this length of through hole is also 20cm, and two reinforcing bars of connection are at least 10cm in through hole, improve reinforcing bar and connect flexural strength.
Further, in order to make screw thread on reinforcing bar not by out exposed, described shoulder hole miner diameter end is provided with and the integrated baffle ring of attachment cap, by the effect of baffle ring, after attachment cap is connected with Connection Block, by baffle ring, screw thread exposed reinforcing bar is blocked.
accompanying drawing explanation:
Fig. 1 is the fractionation structural representation of the utility model embodiment steel reinforcement abutting joints fastening devices.
the specific embodiment:
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1, steel reinforcement abutting joints fastening devices, comprise Connection Block 1 and attachment cap 2, Connection Block 1 is cylindric, and Connection Block 1 central axis is provided with through hole 11, Connection Block 1 two ends are provided with screw thread, attachment cap 2 inside are provided with shoulder hole 22, and ladder hole wall is provided with screw thread, and the larger end in aperture mates with the screw thread of Connection Block 1, aperture is connected with threaded reinforcing bar 3 compared with small end, and the centre of through hole 11 is provided with gear along 12.The length of Connection Block 1 is 20cm, and making like this length of through hole 11 is also 20cm, and two reinforcing bars 3 of connection are 10cm in through hole 11, have improved reinforcing bar 3 to connect flexural strength; Shoulder hole 22 miner diameter ends are provided with and the integrated baffle ring 21 of attachment cap, by the effect of baffle ring 21, after attachment cap 2 is connected with Connection Block 1, by baffle ring 21, the exposed screw thread of reinforcing bar 3 are blocked.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
