Background
the connecting mode of reinforcing bars mainly has ligature overlap joint, mechanical connection, sleeve pipe grout connection and welding, wherein through the telescopic connecting method of reinforcing bar owing to can arrange intensive department homoenergetic nimble operation at narrow and small place reinforcing bar, be convenient for connect and the construction, and reinforcing bar connecting sleeve is prefabricated in the mill, and pollution-free, the no naked light operation during the construction operation has advantages such as environmental protection and safety concurrently.
Chinese patent with application number CN200820187916.2 discloses a steel bar connecting sleeve, mainly comprises two toper sleeves, connecting block, fixed plate and spring, and two toper telescopic major diameter one end link together, and the centre is equipped with the fixed plate, and two toper telescopic inner chambers are equipped with the connecting block of toper form respectively, and the terminal surface of connecting block passes through the spring to be connected with the fixed plate.
Although the reinforcing steel bar connecting sleeve can realize the extension of the reinforcing steel bars along the length direction of the reinforcing steel bars through the end parts of the two fixed reinforcing steel bars, the reinforcing steel bars can only be connected between the two reinforcing steel bars when being connected, the connecting quantity of the reinforcing steel bars is limited, and the plurality of reinforcing steel bars are difficult to be connected simultaneously.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a steel bar connection spare for many connections has the advantage that realizes a plurality of reinforcing bars and connect simultaneously.
In order to achieve the above purpose, the utility model provides a following technical scheme:
A steel bar connection spare for many connections, sleeve including the connecting reinforcement, telescopic inner space sets up to the toper, the one end of the great internal diameter of sleeve sets up to the stiff end, the one end that the stiff end was kept away from to the sleeve sets up to the bar connection end, be equipped with the cover block that is used for the fixed reinforcement in the sleeve, the cover block sets up to split type, the cover block is equipped with the elastic component towards the opening part of sleeve stiff end, telescopic stiff end opening part is connected with connection structure, connection structure's side surface is equipped with a plurality of links, the internal surface of cover block is equipped with the spacing arch that the restriction reinforcing bar breaks away from.
By adopting the technical scheme, the reinforcing steel bar passes through the sleeve block in the process of being inserted into the sleeve, the sleeve block extrudes the elastic piece to move towards the direction of the connecting structure after being subjected to the force of the reinforcing steel bar towards the direction of the connecting structure, the pressure of the outer surface of the sleeve block from the inner wall of the sleeve is reduced due to the increase of the inner diameter of the sleeve in the moving process of the sleeve block, so that the distance between the sleeve block and the sleeve block is increased, the inner diameter of a space formed by the sleeve block in a surrounding mode is increased, when the inner diameter of the surrounding mode of the sleeve block is larger than the diameter of the cross section of the reinforcing steel bar, the elastic piece penetrates through the inner space surrounded by the sleeve block and along the length direction of the elastic piece, when the end part of the reinforcing steel bar is abutted against the connecting structure, the end part of the reinforcing steel bar stops moving in the sleeve, the reinforcing steel bar stops continuously applying force to the sleeve block, the elastic piece also stops continuously applying force to the elastic piece after stopping, so that the sleeve block is blocked in the gap between the inner wall of the sleeve and the steel bar.
When the reinforcing steel bar has a movement trend of separating from the sleeve, the static friction force between the sleeve block and the reinforcing steel bar prevents the separation of the reinforcing steel bar, the inner surface of the sleeve block is provided with the limiting protrusions, the limiting protrusions are matched with the transverse ribs on the surface of the reinforcing steel bar, the friction force generated when the inner wall of the sleeve block is contacted with the reinforcing steel bar is increased by the limiting protrusions in one direction, the resistance of the reinforcing steel bar separating from the space in the sleeve is increased, on the other hand, the limiting protrusions are contacted with the transverse ribs on the surface of the reinforcing steel bar, and the limiting protrusions apply a force opposite to the movement direction of the transverse. The reinforcing bar is when the production leaves telescopic motion trend, drives the sleeve block and removes towards telescopic bar connection end's direction, the sleeve block has reduced the pressure to the elastic component at this in-process, the elastic component is for resumeing the reverse power of applying towards telescopic bar connection end of state to the sleeve block, the contact of sleeve block and reinforcing bar is inseparabler under the effect of sleeve inner wall, make the reinforcing bar when the telescopic motion trend that the production left sleeve inside more firm to its fixed. Because connection structure's side surface is equipped with a plurality of links, a plurality of links provide a plurality of connection sites for connection structure and telescopic being connected, make a plurality of sleeves link together on a connection structure, through inserting a plurality of reinforcing bars in each sleeve, realize the connection of a plurality of reinforcing bars in the equidirectional not, reduced the number at the reinforcing bar connecting piece that the equidirectional setting, practiced thrift the cost of building site construction, enlarged this reinforcing bar connecting piece's range of application.
