Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, and in particular to an auxiliary positioning device for assembled prefabricated columns. Background Art

[0002] Precast concrete is made by tying steel bars and pouring concrete on structural columns in the factory. The bottom of the column is grouted with the reserved steel bars on the floor slab through reserved holes. At the same time, steel bars are also reserved at the top, which are grouted or overlapped with the slabs, beams and other components.

[0003] Before the prefabricated column is hoisted, the reserved steel bars are cleaned and positioned, and the position and spacing of the steel bars are positioned using a pre-processed precise steel bar positioning frame, and the crooked steel bars are straightened. After the straightening is completed, the prefabricated column is lifted at two points and the descent is stopped when it is 300mm away from the installation position. A mirror is used to ensure that the steel bars are accurately aligned with the holes. After alignment, the hoisting personnel slowly lower the prefabricated column by hand, thus completing the connection between the reserved steel bars and the prefabricated column.

[0004] The current plug-in docking method requires manual use of mirrors to ensure that the steel bars are accurately aligned with the holes. Since workers cannot observe the mirror vertically, the reflection angle of the light is tilted, resulting in a certain deviation between the steel bars observed by the workers and the prefabricated holes, which makes it easy for the holes to fail to be aligned. In addition, multiple workers are needed to support and ensure that the prefabricated columns fall vertically for docking. The operation is more cumbersome, and the prefabricated columns are prone to deviation when they fall, resulting in failure to align the holes. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0039] Example 1, reference Figure 1 , Figure 5 , Figure 8 , Fig. 9 , which is the first embodiment of the present invention, provides an auxiliary positioning device for assembled prefabricated columns, the device comprising:

[0040] The straightening mechanism 100 includes a reserved steel bar 101 and a straightening portion 102 disposed on the reserved steel bar 101;

[0041] The splicing mechanism 200 includes a splicing portion 201 disposed on the straightening portion 102, two sets of mounting portions 202 disposed on the splicing portion 201, and a pin removal portion 203 disposed on the splicing portion 201;

[0042] The lifting and hole alignment mechanism 300 includes a torsion portion 301 arranged on the splicing portion 201, a limiting portion 302 arranged on the torsion portion 301, a self-pinning portion 303 arranged in the limiting portion 302, a sliding portion 304 arranged on the limiting portion 302, and a rolling portion 305 arranged on the limiting portion 302.

[0043] During use, the straightening portion 102 is used to straighten the reserved steel bar 101. After the straightening operation is completed, the splicing portion 201 is spliced ​​on the straightening portion 102 through the mounting portion 202, and the sliding portion 304 is pulled and rotated along the limiting portion 302, so that the sliding portion 304 is limited in the middle of the limiting portion 302. At the same time, the sliding portion 304 drives the self-pinning portion 303 to move, thereby releasing the limit of the self-pinning portion 303, and the torsion of the torsion portion 301 drives the limiting portion 302 to make the rolling portion 304 move. 5 rotates, and the combined force of the four groups of rolling parts 305 drives the straightening part 102 to rise along the reserved steel bar 101. The prefabricated column is placed on the top of the straightening part 102 to complete the hole alignment operation between the prefabricated column and the reserved steel bar 101, and the prefabricated column is slowly lowered. The prefabricated column squeezes the straightening part 102 to make the splicing part 201 descend. The splicing part 201 descends and pushes the rolling part 305 to rotate and reset, pulling the installation part 202 to release the limit of the splicing part 201, and the splicing part 201 is removed for the next use of the device.

[0044] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the straightening portion 102 includes a steel bar positioning plate 102a, a steel bar positioning hole 102b arranged on the steel bar positioning plate 102a and matched with the reserved steel bar 101, a splicing hole 102c arranged on the steel bar positioning plate 102a, the splicing hole 102c is located at the corner of the steel bar positioning plate 102a, and a counterweight pressing block 102d is arranged on the steel bar positioning plate 102a; wherein, the size of the steel bar positioning plate 102a is the same as that of the prefabricated column to ensure that it is flush with the prefabricated column, the steel bar positioning hole 102b is matched with the reserved steel bar 101, and is used to straighten the reserved steel bar 101, and at the same time, it can be ensured that when the prefabricated column is aligned with the steel bar positioning plate 102a, the reserved steel bar 101 is aligned with the prefabricated hole of the prefabricated column, so as to ensure the accurate hole alignment of the device, and the splicing hole 102c is opened at the corner of the steel bar positioning plate 102a, and is used to splice the splicing portion 201.

[0045] Furthermore, by setting the counterweight block 102d and moving the counterweight block 102d away from the steel bar positioning plate 102a, the four sets of lifting and hole alignment mechanisms 300 can simultaneously exert force to lift the steel bar positioning plate 102a, thereby preventing the steel bar positioning hole 102b from rubbing against the reserved steel bar 101 or even getting stuck due to unbalanced force on the steel bar positioning plate 102a, thereby increasing the smoothness of the lifting and lowering of the steel bar positioning plate 102a. Moreover, when the counterweight block 102d is placed on the steel bar positioning plate 102a, the torsion of the torque part 301 is exerted on the rolling part 305 instead of the self-pinning part 303, thereby facilitating the unpinning operation of the self-pinning part 303.

[0046] The splicing part 201 includes a splicing triangle plate 201a, a heightened triangle block 201b arranged on the splicing triangle plate 201a, a top arc surface 201c arranged on the heightened triangle block 201b, and a limiting pin hole 201d arranged at the corner of the splicing triangle plate 201a; wherein, the splicing triangle plate 201a is a triangular corner block, used to limit the prefabricated column, so as to facilitate the alignment of the prefabricated column with the steel bar positioning plate 102a, the setting of the heightened triangle block 201b facilitates the insertion of the prefabricated column, the setting of the top arc surface 201c can prevent the end of the self-pinning part 303 from being stuck with the corner of the splicing triangle plate 201a, and ensure the normal use of the device, the limiting pin hole 201d is used to limit the self-pinning part 303, and since the self-pinning part 303 is inclined, it is convenient for the rotation of the self-pinning part 303, so the limiting pin hole 201d is also inclined, so as to facilitate the limiting of the end of the self-pinning part 303.

[0047] The mounting portion 202 includes a long rod 202a disposed on the splicing triangle plate 201a and adapted to the splicing hole 102c, a short rod 202b disposed on the splicing triangle plate 201a and adapted to the splicing hole 102c, the length of the short rod 202b is shorter than the long rod 202a, a connecting plate 202c disposed on the long rod 202a and the short rod 202b, a mounting spring 202d disposed on the long rod 202a and the short rod 202b, and a disassembly handle 202e disposed on the connecting plate 202c; wherein the mounting portion 202 is provided with two groups, which are respectively located at the splicing triangle plate 201a and the short rod 202d. Two surfaces increase the stability of the connection between the spliced ​​triangle plate 201a and the steel bar positioning plate 102a, the long rod 202a is slidably set on the spliced ​​triangle plate 201a, and the short rod 202b is slidably set on the spliced ​​triangle plate 201a. The short rod 202b is shorter than the long rod 202a, which can prevent the two adjacent short rods 202b from conflicting with each other and getting stuck. The connecting plate 202c is fixed at the ends of the long rod 202a and the short rod 202b to facilitate the removal of the long rod 202a and the short rod 202b. The setting of the installation spring 202d ensures the stability of the long rod 202a and the short rod 202b during insertion to prevent them from falling off.

[0048] The disengaging portion 203 includes a disengaging arc plate 203a arranged on the splicing triangle plate 201a, and a disengaging arc surface 203b arranged on the disengaging arc plate 203a, wherein the arc surface of the disengaging arc surface 203b is located at the end of the disengaging arc plate 203a and faces the corner of the splicing triangle plate 201a; wherein the disengaging arc plate 203a is designed to be arc-shaped, and the center of the arc is the same as the center of the circle of the torsion portion 301, thereby ensuring that the disengaging arc plate 203a can be squeezed when the sliding portion 304 rotates.

[0049] The remaining structures are the same as those of Example 1.

[0050] During use, the reserved steel bar 101 is straightened through the steel bar positioning hole 102b on the steel bar positioning plate 102a. After the straightening operation is completed, the splicing triangle plate 201a is squeezed and placed at the corner of the steel bar positioning plate 102a. The corner of the steel bar positioning plate 102a squeezes the long rod 202a to extend the installation spring 202d. When the long rod 202a coincides with the splicing hole 102c, the elastic force of the installation spring 202d drives the long rod 202a and the short rod 202b to be inserted into the splicing hole 102c, thereby completing the splicing and fixing of the splicing triangle plate 201a. When disassembly is required, the disassembly handle 202e is directly pulled to make the long rod 202a away from the splicing hole 102c, and the sliding part 304 is pulled and rotated along the limiting part 302 to limit the sliding part 304 to the middle part of the limiting part 302. At the same time, the sliding part 304 drives the self-pinning part 303 to move, thereby releasing the self-pinning part 30 3, the torque of the torque part 301 drives the limiting part 302 to rotate the sliding part 304, and when the sliding part 304 rotates, it squeezes the pin-off arc surface 203b to make the sliding part 304 rotate, thereby releasing the limit of the sliding part 304. After the sliding part 304 is released from the limit, the self-pinning part 303 automatically resets, and the end of the self-pinning part 303 conflicts with the top arc surface 201c. When the prefabricated column squeezes the steel bar positioning plate 102a to make the spliced ​​triangle plate 201a descend The limiting portion 302 drives the self-pinning portion 303 to rotate, and the end of the self-pinning portion 303 squeezes the top arc surface 201c, so that the end of the self-pinning portion 303 moves along the corner of the splicing triangle plate 201a. When the self-pinning portion 303 coincides with the limiting pin hole 201d, the self-pinning portion 303 is clamped into the limiting pin hole 201d, thereby completing automatic resetting and fixing. The staff does not need to perform the clamping operation separately, and it is convenient for the disassembly and removal of the splicing triangle plate 201a.

[0051] Example 3, reference Figure 8~Figure 12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the torsion part 301 includes a torsion frame 301a arranged at the corner of the spliced ​​triangle plate 201a, a torsion shaft 301b arranged on the torsion frame 301a, a torsion spring 301c arranged on the torsion shaft 301b, and a torsion shaft hole 301d arranged on the torsion shaft 301b; wherein, the torsion frame 301a is fixedly arranged at the corner of the spliced ​​triangle plate 201a and is arranged at 45 degrees, the torsion shaft 301b is rotatably arranged on the torsion frame 301a, and is connected through a damping bearing so that the device can be slowly lifted to prevent the device from bouncing up, and both ends of the torsion shaft 301b extend to the outside of the torsion frame 301a to facilitate the installation of the torsion spring 301c, the torsion spring 301c is fixedly arranged on the torsion shaft 301b, and the torsion shaft hole 301d is used for the sliding of the pin rod 303a to ensure the normal use of the device.

[0052] The limiting part 302 includes a limiting tube 302a disposed on the torsion shaft 301b, the tube core of the limiting tube 302a is the same as the torsion shaft hole 301d, a limiting slide 302b disposed on the limiting tube 302a, and a limiting card slot 302c disposed on the limiting tube 302a and connected to the limiting slide 302b; wherein one end of the limiting tube 302a is fixed on the torsion shaft 301b, and the tube core of the limiting tube 302a is the same as the torsion shaft hole 301d. , ensuring that the self-pin rod 303a can slide in the torsion shaft hole 301d, the limiting slide groove 302b is set on the surface of the limiting tube 302a, and is connected with the limiting card groove 302c to form an L shape, and the limiting can be completed by pulling and then rotating the sliding part 304, and at the same time, the limiting of the self-pin part 303 is released, and when the sliding handle 304a rotates along the limiting card groove 302c, the arc block 304d is close to the unpinned arc plate 203a, ensuring the normal use of the device.

[0053] The self-pinning part 303 includes a self-pinning rod 303a arranged in the limiting tube 302a and adapted to the torsion shaft hole 301d, a self-pinning ball 303b arranged on the self-pinning rod 303a, a self-pinning spring 303c arranged in the limiting tube 302a and connected to the self-pinning rod 303a, and a self-pinning protrusion 303d arranged on the self-pinning rod 303a; wherein, the self-pinning rod 303a is slidably arranged in the limiting tube 302a, the setting of the self-pinning ball 303b reduces the friction between the self-pinning rod 303a and the splicing triangle plate 201a, and facilitates the insertion of the self-pinning rod 303a, the self-pinning spring 303c provides stability for the insertion of the self-pinning rod 303a, and is also used for the automatic resetting of the self-pinning rod 303a, and the self-pinning protrusion 303d is fixed on the surface of the self-pinning rod 303a, and is used to connect with the sliding part 304.

[0054] The sliding portion 304 includes a sliding handle 304a arranged on the limiting tube 302a, a sliding connection block 304b arranged in the sliding handle 304a and adapted to the limiting slide groove 302b, a sliding connection recessed hole 304c arranged on the sliding connection block 304b and adapted to the self-pinning protrusion 303d, and an arc block 304d arranged on the sliding handle 304a; wherein, the sliding handle 304a is slidably arranged on the limiting tube 302a, the sliding connection block 304b is fixedly arranged on the inner surface of the sliding handle 304a, and the sliding connection recessed hole 304c is used to connect with the self-pinning protrusion 303d, so that the sliding handle 304a can drive the self-pinning rod 303a to move.

[0055] Furthermore, the arc block 304d is fixedly arranged on the surface of the sliding handle 304a, the arc block 304d is kept perpendicular to the sliding handle 304a, and is located at the top of the outer surface of the sliding handle 304a. When the sliding handle 304a rotates along the limiting slot 302c, the arc block 304d is offset and approaches the disengaged arc plate 203a. Since the radius of the arc block 304d is larger than the sliding handle 304a, the disengaged arc surface 203b squeezes the arc block 304d to reset the arc block 304d. The arc block 304d drives the sliding handle 304a to make the sliding connection block 304b disengage from the limiting slot 302c, thereby automatically releasing the limit. The corners of the limiting slot 302b and the limiting slot 302c are chamfered to prevent the sliding connection block 304b from being stuck at the corners of the limiting slot 302b and the limiting slot 302c, thereby increasing the smoothness of the device.

[0056] Furthermore, the radius of the sliding handle 304a is r, and the distance between the axis vertical plane of the sliding handle 304a and the inner surface of the disengaged arc plate 203a is r, so the sliding handle 304a can deflect along the inner surface of the disengaged arc plate 203a. Since the radius of the arc block 304d is greater than r, the arc block 304d will inevitably squeeze the disengaged arc surface 203b. The disengaged arc surface 203b squeezes the arc surface of the arc block 304d to make the arc block 304d rotate, and the arc block 304d drives the sliding handle 304a to make the sliding connection block 304b disengage from the limiting slot 302c.

[0057] The rolling part 305 includes an extension rod 305a arranged on the limiting tube 302a, and a roller 305b arranged on the extension rod 305a; wherein the extension rod 305a is fixedly arranged at the end of the limiting tube 302a, and the roller 305b is fixedly arranged at the end of the extension rod 305a, and the roller 305b is a directional roller.

[0058] The remaining structure is the same as that of Example 2.

[0059] During use, the reserved steel bar 101 is straightened through the steel bar positioning hole 102b on the steel bar positioning plate 102a. After the straightening operation is completed, the splicing triangle plate 201a is squeezed and placed at the corner of the steel bar positioning plate 102a. When the long rod 202a coincides with the splicing hole 102c, the elastic force of the installation spring 202d drives the long rod 202a and the short rod 202b to be inserted into the splicing hole 102c, thereby completing the splicing and fixing of the splicing triangle plate 201a. Then, the counterweight pressing block 102d is placed on the steel bar. At the top of the positioning plate 102a, pull the sliding handle 304a to drive the sliding connection block 304b to move along the limiting slide groove 302b, and at the same time, the sliding handle 304a drives the sliding connection block 304b to move the sliding connection concave hole 304c, and the sliding connection concave hole 304c drives the self-pinning protrusion 303d to move the self-pin rod 303a, and the self-pin rod 303a drives the self-pinning ball 303b to move out of the limiting pin hole 201d, thereby releasing the limit of the self-pin rod 303a, and then turn the sliding handle 304a to make the sliding connection block 304b move. 04b is inserted into the limiting slot 302c, thereby limiting the sliding handle 304a to ensure that the self-pin rod 303a will not rebound. Similarly, the sliding parts 304 at the four corners are operated. When the four sets of lifting hole alignment mechanisms 300 are all released from the limit, the counterweight pressing block 102d is moved away from the steel bar positioning plate 102a. The torsion springs 301c at the four corners simultaneously drive the torsion shaft 301b to rotate, and the torsion shaft 301b drives the limiting tube 302a to rotate the roller 305b. The combined force of the four sets of rollers 305b drives the steel bar The positioning plate 102a rises along the reserved steel bar 101. When the spliced ​​triangle plate 201a rises, the limiting tube 302a rotates, and the limiting tube 302a drives the sliding handle 304a to make the arc block 304d close to the de-pinned arc plate 203a. The arc block 304d rotates and squeezes the de-pinned arc surface 203b to make the arc block 304d rotate, thereby releasing the limit on the sliding handle 304a. After the sliding handle 304a is released from the limit, the self-pin rod 303a automatically resets, and the self-pin ball 303b conflicts with the top arc surface 201c.

[0060] The prefabricated column is placed on the top of the steel bar positioning plate 102a to complete the hole alignment operation between the prefabricated column and the reserved steel bar 101, and the prefabricated column is slowly lowered. The prefabricated column squeezes the steel bar positioning plate 102a to make the splicing triangle plate 201a descend, and the splicing triangle plate 201a descends to push the roller 305b to move along the ground. At the same time, the roller 305b drives the limiting tube 302a to deflect the self-pinning rod 303a, and the self-pinning ball 303b squeezes the top arc surface 201c, so that the self-pinning ball 303b moves along the corner of the splicing triangle plate 201a. When the self-pinning ball 303b is matched with the limiting pin hole 201d, the elastic force of the self-pinning spring 303c pushes the self-pinning rod 303a to insert the self-pinning ball 303b into the limiting pin hole 201d, thereby completing the hole alignment operation of the prefabricated column and resetting the device at the same time. At the same time, the self-pinning rod 303a is clamped and fixed, and the disassembly handle 202e is pulled to make the long rod 202a away from the splicing hole 102c to release the limit on the splicing triangle plate 201a, and the splicing triangle plate 201a is removed to facilitate the next use of the device.
