[0002] With the development of prefabricated building construction technology, prefabricated components such as prefabricated columns and prefabricated beams are increasingly used in building construction. During the construction process, the reserved steel bars need to be positioned. At present, most of them are made of single steel plates with standardized holes punched to form steel sleeves. The punching position and hole diameter need to be customized according to the position and diameter of the reserved steel bars. The reuse rate is low. When there are many types of prefabricated columns, more steel sleeves need to be configured, which is troublesome and uneconomical.

[0003] In addition, in order to allow the reserved steel bars to be smoothly inserted into the holes, the size of the holes on the steel bar sleeves needs to be slightly larger than the cross-sectional size of the steel bars, making it difficult for most of the steel bars to be in the ideal position in the center of the holes, resulting in the need for secondary adjustments when they are subsequently connected to the prefabricated columns, which increases the workload. Therefore, it is necessary to provide a highly adaptable prefabricated column steel bar positioning device that can solve the problem of inconvenient positioning of the reserved steel bars for prefabricated columns in the prior art.

DETAILED DESCRIPTION

[0026] The highly adaptable prefabricated column reinforcement positioning device proposed by the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description and claims. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0027] Please see attached Figure 1A highly adaptable prefabricated column steel bar positioning device comprises a steel bar positioning locking wheel 1, a transmission mechanism and a positioning plate 4; a first hollow portion 401 for the reserved steel bars of the prefabricated column to pass through is formed on the positioning plate 4, the transmission mechanism is arranged at the edge of the first hollow portion 401 of the positioning plate 4, and a plurality of steel bar positioning locking wheels 1 are respectively arranged at intervals at the first hollow portion 401 of the positioning plate 4 and are connected to the transmission mechanism for transmission; the positioning plate 4 is placed on the prefabricated column, so that the plurality of steel bar positioning locking wheels 1 are correspondingly sleeved and locked on a plurality of reserved steel bars of the prefabricated column one by one.

[0028] The positioning plate 4 is used to install the highly adaptable prefabricated column steel bar positioning device on the prefabricated column, so that the steel bar positioning locking wheel 1 can position and lock the reserved steel bars on the prefabricated column through the transmission mechanism. The number of steel bar positioning locking wheels 1 can be determined according to the number of reserved steel bars to be positioned and locked. The transmission mechanism is used to synchronously drive all steel bar positioning locking wheels 1, so that each steel bar positioning locking wheel 1 is locked on all reserved steel bars at the same time, and each reserved steel bar is located at the ideal center position of the steel bar positioning locking wheel 1, thereby improving the positioning accuracy of the reserved steel bars.

[0029] Please see attached Figure 3 and attached Figure 4 The steel bar positioning locking wheel 1 includes an external transmission wheel 101, an internal locking wheel 102 and locking teeth 103; the internal locking wheel 102 is rotatably embedded in the inner ring of the external transmission wheel 101 through a rotating bearing, and the outer ring of the external transmission wheel 101 is transmission-connected to the transmission mechanism; a plurality of locking teeth 103 are rotatably connected to the internal locking wheel 102 and are symmetrically arranged about the center of the internal locking wheel 102, and the internal locking wheel 102 is sleeved on the reserved steel bars of the prefabricated column, so that the plurality of locking teeth 103 are circumferentially arranged on the outside of the reserved steel bars and can be rotatably pressed against the outer wall of the reserved steel bars.

[0030] The external transmission wheel 101 rotates relative to the internal locking wheel 102 under the transmission action of the transmission structure, and at the same time, the plurality of locking teeth 103 rotate closer, narrowing the spacing between the plurality of locking teeth 103 and pressing against the outer wall of the reserved steel bars, thereby adapting to reserved steel bars of different sizes and ensuring the positioning effect of the reserved steel bars.

[0031] Preferably, three locking teeth 103 can be arranged at equal intervals and symmetrically around the center, and the number of locking teeth 103 can also be increased as needed. When the locking teeth 103 rotate relative to the internal locking wheel 102, the spacing between the three locking teeth 103 can be reduced to make them gather and close, thereby pressing against the outer wall of the reserved steel bars from three directions to achieve the positioning and clamping effect; since the three locking teeth 103 are symmetrically arranged and move synchronously, the reserved steel bars are subjected to equal pressure from the three locking teeth 103, which can ensure the positioning accuracy and stability of the reserved steel bars, so that they are located at the ideal center position of the internal locking wheel 102. When the locking teeth 103 rotate relative to the internal locking wheel 102, the spacing between the three locking teeth 103 can also be expanded to make them separate and open, thereby facilitating the disassembly and turnover use of the highly adaptable prefabricated column steel bar positioning device.

[0032] Please see attached Figure 4 Each of the locking teeth 103 is a triangular structure, and the locking tooth 103 includes a first angle and a second angle. The first angle is rotatably connected to the internal locking wheel 102 through a fixing pin 104; a tightening arc surface 1031 is formed between the second angle and the first angle, and the tightening arc surface 1031 can be tightened against the outer wall of the reserved steel bar.

[0033] The locking teeth 103 can be flexibly rotated by the fixing pin 104, so that the locking teeth 103 can be closed and pressed against the reserved steel bars or opened and away from the reserved steel bars.

[0034] By setting the pressing arc surface 1031, the arc surface of the reserved steel bar can be better fitted, the contact area is increased, the positioning stability of the reserved steel bar is improved, and the occurrence of slippage is reduced.

[0035] Please see attached Figure 3 The locking tooth 103 also includes a third angle, and a transmission surface 1032 is formed between the third angle and the first angle. A transmission rod 105 is provided on the side of the locking tooth 103, one end of the transmission rod 105 is fixed on the external transmission wheel 101, and the other end of the transmission rod 105 is in contact with and connected to the transmission surface 1032.

[0036] The transmission rod 105 is fixed on the external transmission wheel 101 and rotates synchronously with the external transmission wheel 101. When the transmission rod 105 rotates, it pushes the transmission surface 1032, so that the locking teeth 103 rotate around the fixing pin 104 and approach the reserved steel bar, so that the three locking teeth 103 rotate and close to achieve the purpose of locking and positioning.

[0037] Preferably, the fixing pin 104 can adopt a pin shaft with a coil spring. When the locking tooth 103 rotates close to the reserved steel bar, the coil spring accumulates force. When disassembling, the external transmission wheel 101 drives the transmission rod 105 to rotate in the opposite direction, and the locking tooth 103 is pushed to rotate and open under the elastic force of the coil spring, away from the reserved steel bar, which is convenient for disassembly and can also be suitable for reserved steel bars of larger sizes.

[0038] Please see attached Figure 3 The transmission surface 1032 is an arc structure, and the transmission rod 105 is bent into an L-shaped arc structure, so that the transmission surface 1032 is slidably set on the arc structure of the transmission rod 105.

[0039] The transmission rod 105 with an arc structure guides the transmission surface 1032 with an arc surface structure, so that the transmission rod 105 can push the locking tooth 103 to rotate stably around the fixing pin 104 without being blocked during the rotation.

[0040] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 5 The transmission mechanism includes a positioning gear 2 and a transmission rack 3; the positioning gear 2 is rotatably mounted on the end of the first hollow portion 401 of the positioning plate 4 through a gear shaft, and a pair of transmission racks 3 are slidably arranged at the two side edges of the first hollow portion 401 and are respectively meshed and connected with the two side ends of the positioning gear 2; the external transmission wheel 101 is an external gear and is meshed between the pair of transmission racks 3.

[0041] Preferably, the positioning gear 2 and the transmission rack 3 can be a pair and arranged symmetrically, and the pair of positioning gears 2 and the pair of transmission racks 3 form a rectangular structure, and the overall transmission is more stable. The external transmission wheel 101 has the same size as the positioning gear 2, so that the positioning gear 2 provides a transmission force to the transmission rack 3, and then the transmission rack 3 transmits the transmission force to the external transmission wheel 101, so that the meshing rotation of the external transmission wheel 101 is realized.

[0042] The external transmission wheel 101 is embedded between a pair of transmission racks 3 and is relatively fixed by meshing teeth. The external transmission wheel 101 is driven to rotate only when the pair of transmission racks 3 moves. The external transmission wheel 101 is not easy to slip or fall off. The external transmission wheel 101 can be flexibly arranged according to the position and number of reserved steel bars, and has high adaptability.

[0043] Under the drive of a pair of transmission racks 3, all external transmission wheels 101 between the pair of transmission racks 3 rotate synchronously, so that the synchronous locking and loosening of the positioning locking wheels 1 of the entire row of steel bars can be achieved, thereby achieving the positioning effect of the entire row of reserved steel bars, and the construction efficiency is relatively high.

[0044] Preferably, a slide groove can be set on the positioning plate 4 along the length direction, and a slider matching the slide groove can be set on the transmission rack 3, and the slider is slidably embedded in the slide groove, thereby ensuring the transmission stability and linearity of the transmission rack 3 on the positioning plate 4.

[0045] Please see attached Figure 5The highly adaptable prefabricated column steel bar positioning device also includes a cover plate 5, on which a second hollow portion 501 is formed for reserved steel bars to pass through, so that the cover plate 5 can cover the steel bar positioning locking wheel 1, the transmission mechanism and the positioning plate 4.

[0046] The cover plate 5 can cover the steel bar positioning lock wheel 1, the transmission mechanism and the positioning plate 4, and is used to limit the steel bar positioning lock wheel 1, the positioning gear 2 and the transmission rack 3 to prevent the steel bar positioning lock wheel 1, the positioning gear 2 and the transmission rack 3 from being displaced in directions other than the transmission direction.

[0047] Preferably, wing plates, flanges and other structures can be provided on the cover plate 5, which are used to limit the steel bar positioning locking wheel 1, the positioning gear 2 and the transmission rack 3 after the steel bar positioning locking wheel 1 locks and positions the reserved steel bars, thereby improving the setting stability of the entire highly adaptable prefabricated column steel bar positioning device and preventing the steel bar positioning locking wheel 1 from loosening the positioning of the reserved steel bars.

[0048] Please see attached Figure 6 Several groups of the highly adaptable prefabricated column reinforcement positioning devices are enclosed to form a polygonal structure consistent with the cross-section of the prefabricated column.

[0049] Usually, the cross section of the prefabricated column is a rectangular structure, and reserved steel bars are arranged along the inner sides of the four sides of the rectangular structure. Four sets of highly adaptable prefabricated column steel bar positioning devices can be used to enclose the rectangular structure in sequence to position the reserved steel bars on the inner sides of the four sides. The corresponding number of highly adaptable prefabricated column steel bar positioning devices can be flexibly assembled according to the cross-sectional shape of the prefabricated column, and the adaptability is high.

[0050] Preferably, two adjacent groups of highly adaptable prefabricated column reinforcement positioning devices may share a positioning gear 2, or two adjacent groups of highly adaptable prefabricated column reinforcement positioning devices may be staggered in height to avoid mutual interference and ensure normal installation and transmission functions.

[0051] Preferably, each component of the highly adaptable prefabricated column reinforcement positioning device can be made of materials such as stainless steel, which has high durability. If there is friction between adjacent components, lubricating oil can be applied and regular maintenance can be performed to extend the service life.

[0052] Please see attached Figure 1 To Attachment Figure 6 , the usage method and working principle of the utility model are:

[0053] According to the number of reserved steel bars on one side of the prefabricated column, taking four reserved steel bars as an example, four steel bar positioning locking wheels 1 are selected and arranged on the positioning plate 4 according to the spacing of the reserved steel bars. The steel bar positioning locking wheels 1 are engaged and positioned through a pair of transmission racks 3 to ensure that the positions of the four steel bar positioning locking wheels 1 correspond one-to-one to the four reserved steel bars.

[0054] The positioning plate 4 is placed on the prefabricated column so that the four reserved steel bars respectively pass through the inner locking wheels 102 of the four steel bar positioning locking wheels 1. A locking tooth 103 is rotatably mounted on each inner locking wheel 102 at an interval of 120° through a fixing pin 104, and the three locking teeth 103 are evenly spaced and symmetrically distributed on the outer side of the reserved steel bars.

[0055] The gear shaft of the positioning gear 2 is forced to rotate around the gear shaft manually or by a motor or other equipment, thereby meshing and transmitting a pair of transmission racks 3 through the positioning gear 2. Since the pair of transmission racks 3 are symmetrically meshed at the two side ends of the positioning gear 2 and the external transmission wheel 101, the transmission directions of the pair of transmission racks 3 are opposite, and they can mesh and drive the external transmission wheel 101 to rotate.

[0056] When the external transmission wheel 101 rotates, the three transmission rods 105 rotate synchronously, so that the transmission rod 105 pushes the transmission surface 1032 of the locking tooth 103 to move along the arc structure of the transmission rod 105, and the locking tooth 103 rotates around the fixing pin 104, so that the arc surface 1031 rotates toward the direction of the reserved steel bar, and finally the arc surface 1031 is pressed against the outer wall of the reserved steel bar. The three locking teeth 103 rotate and close synchronously, and the three arc surfaces 1031 are evenly pressed against the reserved steel bar, ensuring reliable clamping of the reserved steel bar, and the reserved steel bar is located at the ideal center position of the steel bar positioning locking wheel 1.

[0057] According to the cross-sectional shape of the precast column, taking the rectangular precast column as an example, four sets of highly adaptable precast column steel bar positioning devices are arranged parallel to the edge of the precast column to form a rectangular structure for positioning the reserved steel bars on the four sides.

[0058] During disassembly, the positioning gear 2 is rotated in the reverse direction, so that a pair of transmission racks 3 drive the external transmission wheel 101 to rotate in the reverse direction, releasing the pressure of the transmission rod 105 on the transmission surface 1032, so that the three locking teeth 103 are rotated and opened synchronously, so that the highly adaptable prefabricated column steel bar positioning device can be removed from the reserved steel bars.

[0059] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
