The invention provides a combined type connection device, which aims to solve the problem that two reinforcing steel bars cannot be simultaneously fastened when being connected through a connector.
The following description refers to the accompanying drawings.
As shown in fig. 2, the present embodiment provides a combined type connecting device for connecting a first reinforcing bar 10 and a second reinforcing bar 20, the combined type connecting device includes a first connector 30, a connecting member 40, a second connector 50 and a fixing member 60, specifically, referring to fig. 3, the first connector 30 has a first threaded hole 31 axially penetrating along itself, and the first connector 30 is configured to be detachably screwed with the first reinforcing bar 10 and the connecting member 40 through the first threaded hole 31 respectively; the second connector 50 comprises two assembling sections 51 which are detachable along the radial direction of the second connector, the two assembling sections 51 are used for being assembled with each other to form a second threaded hole 52, and the second connector 50 is used for being detachably screwed with the second reinforcing steel bar 20 through the second threaded hole 52; the second connector 50 is used for being in clamping connection with the connecting piece 30 along the radial direction; the fixing member 60 is configured to be disposed on the outer periphery of the second adaptor 50 to define the radial positions of the two fitting sections 51 along the second threaded hole 52. It should be understood that in order to increase the area of the fitting section 51 for screwing with the second reinforcing bar 20 and prevent one of the two fitting sections from falling off the second reinforcing bar 20, the second connector 50 needs to be split into two fitting sections uniformly along its own radial direction, i.e. the cross section of the portion of each of the two fitting sections for forming the second threaded hole 52 is semicircular. It should be noted that the first connector 30 and the second connector 50 are used for being assembled with each other through the connecting member 30, and the first connector 30, the connecting member 40 and the second connector 50 are coaxial, so that the first reinforcing bar 10 and the second reinforcing bar 20 are coaxial after being connected through the combined connector. It should be noted that the first connector 30 is a sleeve, and the whole body is cylindrical, but the whole body may also be prism-shaped, circular truncated cone-shaped, or truncated pyramid-shaped, and the configuration may be arbitrary by those skilled in the art.
In the above-mentioned combined type connection device, first, the first connector 30 is connected to the first reinforcing bar 10 and the connecting member 40, respectively; secondly, connecting the two assembling sections 51 with the second steel bar 20 along the radial direction of the first threaded hole 31, and simultaneously clamping and connecting with the connecting piece 30; then, slightly rotating the second connector 50 to make the thread of the second threaded hole 52 aligned with and fastened to the thread of the second steel bar 20, so that the first steel bar 10 and the second steel bar 20 are respectively fastened; finally, the fixture 60 is fitted to the outer circumference of the second adaptor 50, thereby locking the radial positions of the two fitting sections along the second threaded hole 52.
Further, the connecting member 40 has a connecting rod 41 extending axially along itself, and at least a portion of the connecting rod 41 has an external thread adapted to the first threaded hole 31, it can be understood that at least a portion of the connecting rod 41 is a screw, and the connecting rod 41 is used for being in threaded connection with the first threaded hole 31 through the external thread. Furthermore, before the two assembling sections 51 are assembled with each other, the first connector 30 is connected to the connecting member 40 via the connecting rod 41, i.e. the first connector 30 is connected to the connecting member 40 before the second reinforcement bar 20 is connected.
Optionally, the external thread of the connecting rod 41 is not less than 1/2 of the axial length of the first threaded hole 31 along the axial length of the connecting rod 41. This increases the contact area between the connecting rod 41 and the first threaded hole 31, so that the connecting member 40 is connected to the first connector 30 more firmly. In practice, after the first steel bar 10 and the connecting member 40 are connected by the first connector 30, the first steel bar 10 and the connecting rod of the connecting member have a gap in the axial direction, and the external thread of the connecting rod 41 may be screwed into the first threaded hole 31 entirely or partly.
Further, the connecting member 40 further has an engaging portion 42 provided on the outer periphery of the connecting rod 41 in the circumferential direction of the connecting rod 41, and the engaging portion 42 protrudes outward in the radial direction of the connecting rod 41; after the two assembling sections are assembled with each other, the second connector 50 has a connecting hole 53 extending along the axial direction of the second threaded hole 52, the connecting hole 53 has a clamping groove 530 disposed on the inner wall along the circumferential direction and adapted to the clamping portion 42, the clamping groove 530 is recessed outward along the radial direction of the connecting hole 53, the clamping portion 42 is used for clamping into the clamping groove 530, and the section of the connecting hole 53 along the axial direction thereof is substantially "T" shaped. Specifically, the engaging portion 42 and the engaging groove 530 are both circular, and the connecting hole 53 penetrates through the second connector 53 and is different from one end connected with the second steel bar 20. Alternatively, the connection hole 53 communicates with the second threaded hole 52 in the axial direction of the second adaptor 50.
Optionally, the connecting member 40 further has a prism hole 43 disposed on the connecting rod 41 along the axial direction of the connecting rod 41, the prism hole 43 is a blind hole, and the prism hole 43 is used for inserting a disassembling tool. In one specific embodiment, the prismatic hole 43 is a hexagonal prismatic hole into which a hexagon socket is inserted to screw the connection rod 41 into the first threaded hole 31.
Further, the fixing member 60 has a through hole 61 penetrating along its axial direction, and the fixing member 60 is configured to be sleeved on the outer periphery of the second connector 50 through the through hole 61.
Further, the cross section of the outer contour of the second connector 50 and the cross section of the through hole 61 are gradually enlarged along the direction from the connecting piece 40 to the first connector 30, and the outer contour of the second connector 50 is matched with the through hole 61, which can be understood as a section of the second connector 50 and the through hole 61 along the axial direction being wedge-shaped or trapezoid (including right trapezoid). With such a configuration, when the fixing member 60 moves along the connecting member 40 toward the first connector 30, the fixing member 60 has a greater compressive stress on the second connector 50, so that the two assembling sections are assembled more firmly. When the fixing member 60 is disposed on the outer periphery of the second connector 50, the fixing member 60 is previously threaded through the through hole 61 on the second reinforcing bar 20.
In a preferred embodiment, the outer profile of the second connector 50 and the through hole 61 are both truncated cone-shaped, so that the radial compressive stress on the second connector 50 is uniform. In other embodiments, the outer contour of the second connector 50 and the through hole 61 may also be truncated elliptical cone, truncated pyramid. It should be noted that the shape of the outer contour of the fixing member 60 is not particularly limited in the present invention, and is preferably the same as the shape of the through hole 61.
Further, after the two assembling sections are assembled with each other, the fixing member 60 is welded and fixed to the outer periphery of the second connector 50.
In summary, in the combined type connection device provided by the present invention, the combined type connection device is configured to connect a first steel bar and a second steel bar, and the combined type connection device includes a first connector, a connecting member, a second connector and a fixing member, the first connector has a first threaded hole penetrating along an axial direction thereof, and the first connector is configured to be detachably and threadedly connected with the first steel bar and the connecting member through the first threaded hole respectively; the second connector comprises two assembling sections which can be disassembled along the radial direction of the second connector, the two assembling sections are used for being assembled with each other to form a second threaded hole, and the second connector is used for being detachably connected with the second reinforcing steel bar in a threaded mode through the second threaded hole; the second connector is used for being clamped and connected with the connecting piece along the radial direction; the fixing piece is used for being arranged on the periphery of the second connector so as to limit the radial positions of the two assembling sections along the second threaded hole. The first connector, the connecting piece, the second connector and the fixing piece are arranged, so that the first steel bar and the second steel bar are connected; furthermore, before the fixing piece is assembled on the second connector, the second connector can be slightly rotated, so that the threads of the second threaded hole are aligned and fastened with the threads of the second steel bar, and the first steel bar and the second steel bar are fastened simultaneously.
