Description

Technical Field

[0001] The invention relates to the technical field of steel bar connection, in particular to a steel bar connection construction device. Background Art

[0002] The main function of the steel bar connector is to connect two steel bars to form a solid structure. The steel bar connector also has the advantages of being easy to use, safe and reliable, and durable. It does not require the use of welding and other processes, can quickly connect steel bars, and reduce construction difficulty and cost. In construction projects such as bridges, for example, the connection of main bars in steel cages, steel bar connectors have been widely used. There are many types of steel bar connectors, among which connectors that do not require threading and directly limit the transverse ribs are widely used. The main principle is to use a one-way tile structure to limit the transverse ribs of the steel bars. When the current steel bar connection construction device is manually operated to connect the steel bars, if the steel bar head is bent or the cross-section of the steel bar head is skewed, it is easy to cause the steel bar connector to not be inserted in place, and it is not convenient to lock the steel bar after detecting the steel bar in place. If the steel bar is not inserted in place, it is easy to cause hidden dangers such as falling off. At the same time, there is a spacing between the transverse ribs of the steel bar, and the staff cuts the steel bar at different positions. The traditional steel bar connector is not convenient for adapting to tighten the steel bar. The steel bar is prone to shaking after being limited by the tile, affecting the firmness of the steel bar connection. It is also easy to fall off under long-term shaking and other conditions.

The locking connection ring 301 is slidably sleeved on the steel sleeve 101; a circle of sliding limit strips 3011 is fixedly installed on the locking connection ring 301, and a circle of sliding limit strips 3011 slides on the inner side of the steel sleeve 101 respectively; a connecting spring 302 is sleeved inside the steel sleeve 101, and the end of the connecting spring 302 is connected to the locking connection ring 301; the inner side of the locking connection ring 301 rotates Six thorn-shaped clips 303 are dynamically installed, and a row of thorn-shaped protrusions are respectively arranged on the inner side of the six thorn-shaped clips 303; the row of thorn-shaped protrusions on the inner side of the thorn-shaped clips 303 are used to limit the cross ribs of the steel bars; a V-shaped groove 3031 is opened on the outer side of a circle of thorn-shaped clips 303; a limiting groove 3032 is respectively arranged at the front end of a circle of thorn-shaped clips 303; a stop ring 204 is attached to the limiting groove 3032; a V-shaped spring piece 304 is respectively fixedly installed at the end of a circle of thorn-shaped clips 303, and the end of the V-shaped spring piece 304 is elastically attached to the inner side of the steel sleeve 101; the stop ring 204 is used to limit a circle of thorn-shaped clips 303;The locking connection ring 301 elastically fits the tube end limiting ring 103, and the installation sleeve part 1 is used to cooperate with the locking part 2 in place, so that the degree of the steel bars in place can be detected when the steel bars are inserted, so as to avoid the steel bars not being properly connected and affecting the steel bar connection effect, thereby ensuring the steel bar connection strength of the present structure. The locking part 2 in place can utilize its own retractable structure, and only when the steel bars are inserted in place can the limiting one-way locking part 3 be released to control the one-way locking steel bars, which can realize automatic control and ensure the flexibility of use of the present structure. The slidable locking connection ring 301 is easy to disassemble and can be used to disassemble the locking connection ring 301 for replacement. Different types of thorn-shaped clip tiles 303 can be used, and the spacing and size of a row of thorn-shaped protrusions on the inner side of the thorn-shaped clip tile 303 can be preset in multiple specifications, which can be conveniently adapted to different steel bar connection requirements, such as spiral cross ribs and crescent-shaped cross ribs. After the cylinder end limiting ring 103 is rotated and disassembled, the locking connection ring 301 can be removed. When the steel bar needs to be connected, the steel bar can be directly inserted into the steel bar sleeve 101. During the process, the stop ring 204 will limit the stop groove 3032, and the thorn-shaped clip tile 303 cannot fit the limit transverse rib until the steel bar head touches and squeezes the locking column 201 in place. The locking column 201 in place is squeezed and retracted, compressing the spring 202 in place. When the locking column 201 in place retracts, the stop ring 204 is driven to retract together until the limiting groove 3032 is not blocked. At this time, under the pressure of the V-shaped spring 304, the thorn-shaped clip tile 303 can be retracted, and the inner row of thorn-shaped protrusions are inserted between the transverse ribs. The thorn-shaped structure of the thorn-shaped clip tile 303 is used to limit the transverse rib in one direction to prevent loosening. The six rows of leakage holes 1011 are used to leak concrete slurry, which can facilitate the improvement of the integrity of the structure during subsequent pouring construction. ;

[0037] Among them, the swing control part 4 includes: a swing adapter ball head 401 and an insert fitting disk 402, the swing adapter ball head 401 is sleeved in the spherical groove on the locking column 201 in place; the insert fitting disk 402 is fixedly installed on the end of the swing adapter ball head 401; the insert fitting disk 402 is used to fit the end of the steel bar; the swing control part 4 also includes: a steel bar end ring 403, a steel bar end ring 403 is fixedly installed on the insert fitting disk 402, and the inner side of the steel bar end ring 403 is a slope structure; the steel bar end ring 403 is used to sleeve the end of the steel bar, and the swing control part 4 used, using its own swing adapter ball head 401 The structure of being able to swing at multiple angles can be used to detect the straightness of the steel bar head, so as to avoid the steel bar head end from being cut due to factors such as improper operation. The end of the steel bar head is skewed. When the end of the steel bar head is skewed, the length of the steel bar sleeve 101 inserted completely will be shortened, which cannot meet the needs of a firm connection. The present structure can improve the standardization of the steel bar end processing, improve the quality of steel bar connection, and avoid improper operation by workers. When the steel bar head is skewed, the skewed part of the steel bar head end will squeeze the plug-in fitting disk 402. After the plug-in fitting disk 402 is squeezed by the skewed steel bar head, the plug-in fitting disk 402 will be skewed, and one side of the plug-in fitting disk 402 will first touch the limit disk 203. At this time, the steel bar cannot be pushed forward, and the locking column 201 in place cannot be completely retracted, thereby realizing the end straightness detection. The skewed steel bar head cannot be connected and used normally, and the end needs to be straightened before connection.

[0038] The locking locating member 5 comprises: a spring bolt 501, a locking post 502 and a locking spring 503. The spring bolt 501 is threadedly connected to the steel sleeve 101; the locking post 502 is slidably inserted into the steel sleeve 101, and the diameter of the locking post 502 is smaller than the width of the stop groove 2011; the locking post 502 is used to insert into the stop groove 2011; a locking spring 503 is fixedly installed at the bottom of the spring bolt 501, and the end of the locking spring 503 is connected to the locking post 502; the locking post 502 elastically fits the locking column 201 in place, and the locking positioning piece 5 can be used to control the positioning of the locking column 201 in place after it is fully retracted, which can ensure the stability of the locking column 201 in place after retraction, and can automatically limit the position, which is more flexible and convenient, and ensures the efficiency of steel bar connection. When the locking column 201 in place retracts, until the locking column 201 in place is fully retracted and close to the spacer 104, at this time, under the elastic extrusion of the locking spring 503, the locking column 502 can be pushed into the stop groove 2011 for positioning.

[0039] Embodiment 2, on the basis of embodiment 1, the rotating tensioning member 6 comprises: a rotating connection ring 601 and a tapered hole 6011, the rotating connection ring 601 is rotatably mounted on the inner side of the steel sleeve 101; a tapered hole 6011 is opened on the side of the rotating connection ring 601; the edge of the tapered hole 6011 is attached to the tapered head bolt 102; the tapered head bolt 102 is used to squeeze the edge of the tapered hole 6011 to drive the rotating connection ring 601 to rotate; the rotating tensioning member 6 also comprises: a tightening tapered block 602, a circle of tightening tapered blocks 602 is fixedly mounted on the inner side of the rotating connection ring 601, and a circle of tightening tapered blocks 602 is respectively located between a circle of thorn-shaped clip tiles 303; the tightening tapered block 602 is staggered with the V-shaped groove 3031 The conical block 602 is screwed to squeeze the thorn-shaped clip tile 303 inward; the rotating tensioning member 6 also includes: a threaded limiting ring 603, which is threadedly connected to the inner side of the steel sleeve 101; the threaded limiting ring 603 is attached to the other end of the connecting spring 302; the threaded limiting ring 603 is used to limit the rotating connecting ring 601, and the rotating tensioning member 6 can be used for radial rotation to limit the thorn-shaped clip tile 303, which can avoid the problem that the traditional method of relying on elastic clamps and other means to make the thorn-shaped clip tile 303 fit the steel bar is not stable enough. At the same time, when the rotating tensioning member 6 rotates radially, a circle of limiting thorn-shaped clip tiles 303 can be controlled to move to one side of the spacer 104, which can be used to pull the steel bar inward, Ensure that the thorn-shaped protrusions on the inner side of the thorn-shaped tile 303 can fit tightly against the transverse ribs of the steel bars to avoid clearance swing. Because in actual steel bar cutting, the distance between the cutting position and the nearest transverse rib is difficult to guarantee, which results in that after the transverse ribs of the steel bars are clamped by the thorn-shaped tile 303, the steel bars can still have room to swing in the axial direction. This structure can reduce clearance swing, improve connection stability, and avoid loosening. After the thorn-shaped tile 303 limits the transverse ribs, the cone head bolt 102 is rotated to squeeze the edge of the conical hole 6011. At this time, the conical hole 6011 will rotate, driving the inner circle to tighten the conical block 602, squeezing the V-groove 3031, and utilizing the V-shaped structure of the V-groove 3031. When the groove 3031 is squeezed by the tightening conical block 602, the thorn-shaped clamping tile 303 can be compressed and contracted inwardly, and can be close to the steel bar, no longer relying solely on the elastic squeezing of the V-shaped spring piece 304. At the same time, by tightening the conical block 602 and the V-shaped groove 3031, the V-shaped groove 3031 will be squeezed on the side close to the spacer 104, driving the locking connection ring 301 and the thorn-shaped clamping tile 303 to move to the side of the spacer 104. The thorn-shaped clamping tile 303 will use the inner thorn-shaped protrusion to drive the steel bar to move to the side of the spacer 104, which can reduce the gap between the inner thorn-shaped protrusion of the thorn-shaped clamping tile 303 and the cross rib of the steel bar, so that the steel bar can be stably clamped, ensuring the connection strength during the subsequent pouring of concrete.

[0040] The working principle of this embodiment is as follows: when it is necessary to connect the steel bars, the steel bars can be directly inserted into the steel bar sleeve 101. During the process, the stop ring 204 will limit the stop groove 3032, and the thorn-shaped clip 303 cannot fit the limiting transverse rib until the steel bar head touches and squeezes the locking column 201 in place. The locking column 201 in place is squeezed and retracted, compressing the spring 202 in place. When the locking column 201 in place retracts, the stop ring 204 is driven to retract together until the limiting groove 3032 is not blocked. At this time, under the squeezing of the V-shaped spring piece 304, the thorn-shaped clip 303 can be retracted, and a row of thorn-shaped protrusions on the inside are inserted between the transverse ribs to take advantage of the The thorn-shaped structure of the thorn-shaped clip 303 is used to limit the transverse rib in one direction to prevent it from loosening. When the straight steel bar head is inserted into the steel bar sleeve 101, the steel bar head is used to touch the plug-in fitting disk 402, and the steel bar end ring 403 is sleeved on the steel bar head for auxiliary limiting. The swinging adapter ball head 401 can be pushed to drive the locking column 201 in place to retract, and the thorn-shaped clip 303 can shrink normally for one-way limiting. On the contrary, when the steel bar head is skewed, the skewed part of the steel bar head end will squeeze the plug-in fitting disk 402. After the plug-in fitting disk 402 is squeezed by the skewed steel bar head, the plug-in fitting disk 402 will be released. When the locking column 201 is retracted, the locking column 201 is completely retracted and close to the spacer 104, and the locking column 502 can be pushed into the stop groove 2011 for positioning under the elastic compression of the locking spring 503. When the locking column 502 needs to be removed, the spring bolt 501 can be rotated; after the thorn-shaped clip 303 limits the cross rib, the cone head bolt 102 can be rotated to squeeze the cone The edge of the conical hole 6011, at this time, the conical hole 6011 will rotate, driving the inner circle to tighten the conical block 602, squeezing the V-shaped groove 3031, and the thorn-shaped clamping shoe 303 can be compressed and contracted inwardly. At the same time, the side of the V-shaped groove 3031 close to the spacer 104 will also be squeezed, driving the locking connection ring 301 and the thorn-shaped clamping shoe 303 to move to the side of the spacer 104, and the thorn-shaped clamping shoe 303 will use the inner thorn-shaped protrusion to drive the steel bar to move to the side of the spacer 104, which can reduce the gap between the inner thorn-shaped protrusion of the thorn-shaped clamping shoe 303 and the cross rib of the steel bar, so that the steel bar can be stably clamped.
