The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 8, in the present invention, there is provided a steel structural connection member for a fabricated building beam column, which mainly includes a first connector 1 and a second connector 2 which are engaged with each other.
The two connecting pieces are preferably steel members and can be fixed on the precast beam or the precast column at will, and in particular, in fig. 1, only the structural form that the first connecting piece 1 is fixed on the precast beam a and the second connecting piece 2 is fixed on the precast column B (the connecting pieces are fixed on the annular sleeve in the figure, the annular sleeve is fixed on the precast beam and the precast column through bolts) is shown, and besides the use state shown in fig. 1, the steel structure connecting member can also realize the assembly connection between the precast column and the assembly connection between the precast beam and the precast column.
With respect to the two connectors, reference is made to FIG. 1
The second connecting piece 2 comprises at least one connecting clamping sleeve 21, each connecting clamping sleeve 21 is provided with a connecting clamping groove, the section of each connecting clamping groove is an inverted trapezoid which is sunken towards the direction away from the first connecting piece 1, and the length of one side of the inverted trapezoid, which is close to the first connecting piece 1, is smaller than the length of one side of the inverted trapezoid, which is away from the first connecting piece 1;
the first connecting piece 1 comprises at least one group of connecting mechanisms, the connecting mechanisms can be inserted into the connecting clamping grooves in a one-to-one correspondence mode, each group of connecting mechanisms comprises N rotary plates 11 which are arranged in a ring-shaped array mode and can rotate independently, N is more than or equal to 2, and the connecting mechanisms form a contracted state or an expanded state through the rotation of the N rotary plates 11.
In particular
Under the shrinkage state, the distance between the free ends of N rotating plates 11 is smaller than the distance between the rotating installation ends of N rotating plates 11, so that the whole first connecting piece 1 forms a conical structure shown in fig. 1, 2 and 5, under the structure, the free end size of the first connecting piece 1 is smaller than the opening size of a connecting clamping groove, thereby the free end of the first connecting piece 1 is conveniently inserted into the connecting clamping groove, and automatic correction can be realized based on the inclined plane of the conical structure in the inserting process, so that the assembly and positioning accuracy of two connecting pieces and a beam column is ensured.
After inserting, the rotating plates 11 rotate to the unfolding state of the connecting mechanism, at this time, the distance between the free ends of the N rotating plates 11 is larger than the distance between the rotating installation ends of the N rotating plates 11, and the inclination of each rotating plate 11 is identical to that of the inverted trapezoid bevel edge, so that the N rotating plates 11 can be stably locked in the connecting clamping groove, and stable assembly between the two connecting pieces and the beam column is realized.
Above-mentioned, when n=2, two rotating plates 11 are set up relatively, then only can realize correction and locking in single direction at this moment, based on this preferred setting up the connection draw-in groove be the ring channel, and N is greater than or equal to 3, makes every group connect cutting ferrule 21 and coupling mechanism homoenergetic and realizes multidirectional correction and locking that corresponds.
In the drawings of the present invention, the structure of the whole steel structure connecting member is preferably shown when n=4, in which 4 rotating plates 11 form a rectangular pyramid in the contracted state, and the connecting grooves are correspondingly defined as rectangular pyramid structures, so that the locking definition in the six degrees of freedom of front, rear, left, right, upper and lower can be accurately and stably realized based on the guiding and rotating of the rotating plates 11.
Further, as can be seen in fig. 3, each set of the above-mentioned connection mechanisms further includes:
a first screw 14 rotatable about an axis;
the driving seat 12 is positioned between the N rotating plates 11 and can reciprocate along the insertion direction of the connecting mechanism, and the first lead screw 14 spirally penetrates through the driving seat 12 along the insertion direction of the connecting mechanism;
the N supporting plates 13 are rotatably connected between the N rotating plates 11 and the driving seat 12 in a one-to-one correspondence manner.
When the integral connection mechanism is in the contracted state, the distance between the two ends of the supporting plate 13 is larger than the distance between the driving seat 12 and the rotating mounting end of the rotating plate 11, and based on the distance, the assembly principle shown in fig. 5-6 can be combined:
at the time of initial assembly, the driving seat 12 is close to the rotation mounting end of the rotating plate 11 as shown in fig. 5, thereby defining N rotating plates 11 to be in a contracted state by the N supporting plates 13, and based on the contracted state, the free end of the connecting mechanism is smoothly inserted into the connecting clamping groove of the connecting clamping sleeve 21;
after the insertion, the first screw rod 14 is rotated, so that the driving seat 12 is driven to move along the direction of the first screw rod 14 toward the free end of the rotating plate 11, and the N supporting plates 13 are driven to rotate, so that the N rotating plates 11 are driven to be gradually unfolded, and an unfolding state shown in fig. 6 is formed (the process is similar to the opening process of the umbrella), in this state, the inclination of each rotating plate 11 is the same as the inclination of the inverted trapezoid bevel edge, and based on the inclination, the N rotating plates 11 are limited in the connecting clamping groove and cannot be separated, so that stable locking is realized.
Based on the rotational driving of the first screw 14, the corresponding:
the second connecting piece 2 further comprises a second base 22 fixed to the side of the connecting ferrule 21 facing away from the first connecting piece 1, and a rotatable second threaded spindle 23 is provided on the second base 22.
As shown in fig. 7, one end of the first screw rod 14 and one end of the second screw rod 23, which are close to each other, are respectively provided with a bump and a groove that can be clamped with each other, and when the N rotating plates 11 are completely inserted into the connecting clamping groove, the first screw rod 14 and the second screw rod 23 are just clamped with each other through the bump and the groove, so that the first screw rod 14 and the second screw rod 23 are combined to form a complete driving screw rod. The turbine 24 coaxially connected with the second screw 23 is arranged in the second base 22, a rotatable worm 25 is spirally meshed with one side of the turbine 24, and a rotating shaft at one end of the worm 25 extends to the outside of the second base 22, so that the worm 25 is rotated outside the second base 22 to drive the turbine 24 to rotate, thereby driving the whole driving screw to rotate, and moving driving of the upper driving seat 12 is realized based on the turbine.
Under the cooperation of the structure, the locking operation of the first connecting piece 1 and the second connecting piece 2 is more convenient. Preferably, referring to fig. 6, in the unfolded state of the integral connection mechanism, the driving seat 12 is screwed to the clamping position of the first screw 14 and the second screw 23, so as to realize the fixed connection of the first screw 14 and the second screw 23, and further locking of the first connecting piece 1 and the second connecting piece 2 is formed based on the fixed connection. As can be seen from fig. 8, it is preferable that the turbine 24 includes an inner wheel 241 and an outer wheel 242 coaxially assembled; wherein:
the second lead screw 23 is fixed on the inner wheel 241, and the inner wheel 241 is in damping rotation connection with the second base 22 through a damping rotating shaft;
a rotatable ratchet 243 is provided between the inner wheel 241 and the outer wheel 242, and the inner wheel 241 and the outer wheel 242 are engaged with each other by the ratchet 243 to form an inner friction unidirectional ratchet mechanism.
In summary, when the worm 25 rotates in the forward direction, the outer wheel 242 engaged with the worm rotates (anticlockwise rotation in the view of fig. 8), and at this time, the outer wheel 242 is clamped between the ratchet 243 and the inner wheel 241, so as to drive the inner wheel 241 and the second screw 23 to rotate, thereby realizing the above-described movement driving of the driving seat 12 (the driving seat 12 moves along the direction in which the first screw 14 is located toward the free end of the rotating plate 11). When the worm 25 is reversely rotated, the worm 25 drives the outer wheel 242 to reversely rotate (clockwise rotation in view of fig. 8), and at the moment, the rotation of the ratchet 243 causes the relative rotation between the outer wheel 242 and the inner wheel 241, so that the integral driving screw cannot be reversely rotated, that is, the back movement of the driving seat 12 cannot be realized, and the first connecting piece 1 and the second connecting piece 2 form complete locking after being matched, thereby effectively improving the stability of the integral structure connection.
Furthermore, each group of connecting mechanisms comprises N mounting clamping seats 15 which are arranged in an annular array, and the rotating plates 11 are correspondingly connected to the mounting clamping seats 15 in a one-to-one rotation manner; a limiting hole is further formed in each connecting clamping sleeve 21, the limiting holes are columnar along the inserting direction of the connecting mechanism, and the limiting holes are connected to one side, close to the first connecting piece 1, of the connecting clamping grooves in a one-to-one correspondence mode.
As can be seen from the above description and fig. 4, when n=4, the limiting hole forms a quadrangular prism-shaped through hole as shown in b in fig. 4, and the through hole is connected with the opening of the connecting slot at a, thereby forming a limiting structure between the two connecting pieces. Specifically, in the assembly process, automatic correction is realized along with the conical guiding of the N rotating plates 11, so that the mounting clamping seat 15 can be accurately inserted into the limiting hole according to the state shown in fig. 6 after the two connecting pieces are inserted and connected, and thus, the structural limitation is further realized. In this limitation, in order to ensure that the rotating plate 11 can be effectively unfolded, it is preferable to set the length of the mounting holder 15 to be not smaller than the length of the limitation hole according to fig. 6, so as to ensure that the rotating plate 11 can be effectively rotated to a structural state in which the unfolded inclination is the same as the inclination of the inverted trapezoid hypotenuse.
In addition, the first connector 1 further includes a first base 16, and a plurality of reinforcing blocks 17 are disposed on the first base 16, and the length of the reinforcing blocks 17 does not exceed the length of the limiting hole along the insertion direction of the connecting mechanism; the second connector 2 further comprises a plurality of reinforcing ribs 26 fixed on the outer side wall of the connecting sleeve 21, and one end of the reinforcing rib 26 near the first connector 1 is provided with a matching groove 27 which can be clamped into the reinforcing block 17. As can be seen from this, in conjunction with fig. 6, after the N rotating plates 11 are completely inserted into the connecting clamping grooves, the plurality of reinforcing blocks 17 are also inserted into the matching grooves 27 in a one-to-one correspondence manner, so as to further improve the matching stability of the first connecting member 1 and the second connecting member 2.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
