Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pedestal construction, and particularly relates to a positioning device for a prestressed column fixed end anchor and a column main reinforcement. Background Art
[0002] At present, the vertical prestressed system mostly adopts the self-locking anchor system, which is convenient to construct and simple in process. The self-locking anchor system is mainly composed of fixed end anchor, cable body, embedded pipeline and tension end anchor. Among them, the verticality of the fixed end anchor and the verticality of the main reinforcement of the column directly affect the quality of the prestressed column.
[0003] The fixed-end anchor of the self-locking anchor system is usually pre-buried in the pedestal together with the main reinforcement of the column. During the casting process of the pedestal, the fixed-end anchor and the main reinforcement of the column are very likely to be skewed, resulting in their verticality not meeting the requirements. In the prior art, in response to the above situation, the main reinforcement of the column is inserted into the hole of the positioning plate before casting the pedestal, thereby limiting the tendency of the main reinforcement of the column to skew. This method requires ensuring that the positioning plate itself is level, but when adjusting the level of the positioning plate itself, current technology often uses the method of manually pulling the positioning plate and observing the level of the positioning plate with the naked eye. This method has the disadvantages that the verticality of the main reinforcement of the column and the verticality of the fixed-end anchor do not meet the design requirements, and the positioning accuracy is low.

[0030] 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 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.
[0031] like Figure 1 and Figure 2 As shown, the positioning device for the fixed end anchor of the prestressed column and the main reinforcement of the column provided by the utility model comprises a positioning plate 1, an adjustment mechanism 9 and a horizontal detection mechanism 7.
[0032] The positioning plate 1 has a first positioning hole 3 for the fixed end anchor 14 to pass through and a second positioning hole 2 for the column main reinforcement 15 to pass through. One end of the adjusting mechanism 9 is arranged on the positioning plate 1, and the other end is used to be arranged on the foundation pit enclosure. There are multiple adjusting mechanisms 9. Multiple adjusting mechanisms 9 are arranged around the positioning plate 1. Among them, the length of the adjusting mechanism 9 located between the positioning plate 1 and the foundation pit enclosure can be adjusted to adjust the horizontality of the positioning plate 1 by adjusting the length of the adjusting mechanism 9 located between the positioning plate 1 and the foundation pit enclosure. The horizontal detection mechanism 7 is arranged on the positioning plate 1. The horizontal detection mechanism 7 can detect the horizontality of the positioning plate 1.
[0033] When the positioning device for the fixed end anchor of the prestressed column and the main reinforcement of the column is working, the fixed end anchor 14 and the main reinforcement 15 of the column can be respectively installed on the first positioning hole 3 and the second positioning hole 2 of the positioning plate 1, and then the horizontality of the positioning plate 1 is adjusted by the adjusting mechanism 9, and finally the horizontality of the positioning plate 1 is detected by the horizontal detection mechanism 7. If the horizontality of the positioning plate 1 does not meet the requirements, the steps of adjusting the horizontality of the positioning plate 1 by the adjusting mechanism 9 and the steps of detecting the horizontality of the positioning plate 1 by the horizontal detection mechanism 7 are repeated until the horizontality of the positioning plate 1 meets the requirements. After the horizontality of the positioning plate 1 meets the requirements, it is very convenient to improve the verticality of the fixed end anchor 14 and the verticality of the column main reinforcement 15, so that the verticality of the fixed end anchor 14 and the verticality of the column main reinforcement 15 meet the design requirements, and high-precision positioning of the fixed end anchor 14 and the column main reinforcement 15 is achieved.
[0034] Moreover, in the positioning device of the anchor of the fixed end of the prestressed column and the main reinforcement of the column, there are multiple adjusting mechanisms 9, and the multiple adjusting mechanisms 9 are arranged around the positioning plate 1. The length of the adjusting mechanism 9 located between the positioning plate 1 and the foundation pit enclosure can be adjusted, so that the upper and lower heights of at least one direction of the positioning plate 1 can be adjusted by adjusting the length of at least one adjusting mechanism 9 located between the positioning plate 1 and the foundation pit enclosure among the multiple adjusting mechanisms 9, thereby realizing the adjustment of the horizontality of the positioning plate 1 (for example, when the height of one direction of the positioning plate 1 is lower, and the heights of other directions are higher, the length of the adjusting mechanism 9 at the direction with lower height can be shortened, so that the height of the positioning plate 1 in this direction is increased, and the horizontality of the positioning plate 1 is improved). The adjustment method of the horizontality of the positioning plate 1 is simple and fits the construction site. Moreover, compared with the traditional method of judging the horizontality of the positioning plate 1 by naked eye observation, the method of detecting the horizontality of the positioning plate 1 by the horizontal detection mechanism 7 greatly improves the accuracy of the horizontality of the positioning plate 1.
[0035] In addition, in the positioning device of the fixed-end anchor of the prestressed column and the main reinforcement of the column, the positioning plate 1 has a first positioning hole 3 for the fixed-end anchor 14 to pass through and a second positioning hole 2 for the column main reinforcement 15 to pass through. Compared with the traditional positioning plate 1 which only has the second positioning hole 2, the column main reinforcement 15 and the fixed-end anchor 14 can be positioned at the same time, thereby facilitating the simultaneous improvement of the verticality of the fixed-end anchor 14 and the verticality of the column main reinforcement 15.
[0036] In this embodiment, the length of the adjustment mechanism 9 can be adjusted. In this way, it is easier to adjust the length of the adjustment mechanism 9 located between the positioning plate 1 and the foundation pit enclosure. It can be understood that in other embodiments, the length of the adjustment mechanism 9 may not be adjustable. In this case, a plurality of connection points arranged in sequence may be provided in the length direction of the adjustment mechanism 9, and each connection point can be connected to the foundation pit enclosure. When the length needs to be adjusted, the connection points at different positions can be connected to the foundation pit enclosure at the same position.
[0037] Specifically, in this embodiment, Figure 3As shown, the adjustment mechanism 9 includes a first pull rod 8a and a second pull rod 8b. One end of the first pull rod 8a is a sleeve end 17 with an internal thread, and the other end is a first connecting end. One end of the second pull rod 8b is a threaded end 21 with an external thread, and the other end is a second connecting end. The threaded end 21 is inserted into the sleeve end 17 and the threaded end 21 is screwed to the sleeve end 17. One of the first connecting end and the second connecting end is arranged on the positioning plate 1, and the other is used to be arranged on the foundation pit enclosure. In this way, by controlling the relative rotation of the first pull rod 8a and the second pull rod 8b, the length of the adjustment mechanism 9 can be increased or shortened, which is very convenient for adjusting the length of the adjustment mechanism 9. It can be understood that in other embodiments, the adjustment mechanism 9 can also adopt other structures to achieve telescopic. It should be noted that in this embodiment, the length adjustment range of the adjustment mechanism 9 is limited, and it belongs to a micro-adjustment mechanism 9, that is, the length of the threaded end 21 is very small, for example, the length of the threaded end 21 is 2cm-20cm.
[0038] More specifically, in the present embodiment, the outer diameter of the sleeve end 17 is greater than the outer diameter of the first connection end. In this way, the volume of the first connection end can be reduced. It is understood that in other embodiments, the outer diameter of the sleeve end 17 may be the same as the outer diameter of the first connection end. More specifically, in the present embodiment, the threaded end 21 and the second connection end are two independent components. In this way, it is easier to make the second pull rod 8b. It is understood that in other embodiments, the threaded end 21 and the second connection end may also be integrally formed. More specifically, in the present embodiment, the threaded end 21 and the second connection end are embedded 20 to prevent the second connection end from rotating and falling off during the rotation of the threaded end 21. More specifically, in the present embodiment, the second connection end has a slot, and the threaded end 21 has a block, which is stuck in the slot, so that the threaded end 21 and the second connection end are embedded 20.
[0039] In the present embodiment, the adjusting mechanism 9 further includes a locking nut 18. The locking nut 18 is threadedly connected to the screw end and can move toward or away from the sleeve end 17 on the screw end. When it is necessary to adjust the length of the adjusting mechanism 9, the locking nut 18 is controlled to move away from the sleeve end 17 so that the locking nut 18 is spaced apart from the sleeve end 17. After the length adjustment of the adjusting mechanism 9 is completed, the locking nut 18 is controlled to move toward the sleeve end 17 so that the locking nut 18 abuts against the sleeve end 17. In this way, the screw end can be effectively prevented from loosening after the length is adjusted. It can be understood that in other embodiments, other locking structures can also be used to replace the locking nut 18.
[0040] In this embodiment, the adjustment mechanism 9 further includes an adjustment nut 19. The adjustment nut 19 is disposed between the second connection end and the threaded end 21. In this way, the first pull rod 8a and the second pull rod 8b can be controlled to rotate relative to each other by applying force to the adjustment nut 19, which is very convenient for applying force. It can be understood that in other embodiments, the adjustment nut 19 can also be omitted, and in this case, the first pull rod 8a and the second pull rod 8b can be controlled to rotate relative to each other by directly applying force to the second pull rod 8b.
[0041] In this embodiment, one end of the adjustment mechanism 9 is detachably connected to the positioning plate 1. In this way, it is very convenient to disassemble and assemble the adjustment mechanism 9. It can be understood that in other embodiments, one end of the adjustment mechanism 9 can also be fixedly connected to the positioning plate 1. Specifically, in this embodiment, the positioning plate 1 has a hanging hole. One end of the adjustment mechanism 9 is inserted into the hanging hole. In this way, it is very convenient to connect the adjustment mechanism 9 to the positioning plate 1.
[0042] In the present embodiment, the end of the adjusting mechanism 9 away from the positioning plate 1 is detachably connected to the foundation pit enclosure. In this way, it is very convenient to disassemble and assemble the adjusting mechanism 9. It can be understood that in other embodiments, the end of the adjusting mechanism 9 away from the positioning plate 1 can also be fixedly connected to the foundation pit enclosure. Specifically, in the present embodiment, the end of the adjusting mechanism 9 away from the positioning plate 1 has a hook. The adjusting mechanism 9 is hung on the foundation pit enclosure through the hook. In this way, it is very convenient to connect the adjusting mechanism 9 to the foundation pit enclosure. Specifically, in the present embodiment, the adjusting mechanism 9 is hung on the steel plate 12 pile of the foundation pit enclosure through the hook.
[0043] In the present embodiment, the positioning plate 1 is square. Two adjustment mechanisms 9 are provided on each side of the positioning plate 1. In this way, it is not only convenient for multiple adjustment mechanisms 9 to stably support the positioning plate 1, but also the number of adjustment mechanisms 9 can be relatively small, simplifying the structure. It can be understood that in other embodiments, one or more (greater than or equal to three) adjustment mechanisms 9 can also be provided on each side of the positioning plate 1. It can be understood that in other embodiments, the shape of the positioning plate 1 can also be set to a circle or a polygon (the number of sides is greater than or equal to five) according to actual needs.
[0044] In this embodiment, if Figure 1 and Figure 2As shown, the positioning plate 1 is square. The horizontal detection mechanism 7 includes four horizontal bubble tubes 7a. The four horizontal bubble tubes 7a are respectively arranged at the edges of the positioning plate 1 in four directions. Among them, when the bubbles in the four horizontal bubble tubes 7a are all located in the middle of the horizontal bubble tubes 7a, the positioning plate 1 is in a horizontal state. In this way, it is very convenient to detect the horizontality of the positioning plate 1. It can be understood that in other embodiments, other horizontal detection mechanisms 7 can also be used to replace the horizontal bubble tubes 7a. Specifically, in this embodiment, the four horizontal bubble tubes 7a are respectively arranged at the edges of the four directions of the upper surface of the positioning plate 1. It can be understood that in other embodiments, the four horizontal bubble tubes 7a can also be respectively arranged at the edges of the four directions of the lower surface of the positioning plate 1 or respectively arranged at the four sides of the positioning plate 1.
[0045] In this embodiment, the positioning device of the fixed end anchor of the prestressed column and the main reinforcement of the column also includes an anchor locking mechanism 16. The anchor locking mechanism 16 is arranged on the positioning plate 1. The anchor locking mechanism 16 can lock or unlock the positioning plate 1 and the fixed end anchor 14. In this way, when the horizontality of the positioning plate 1 meets the requirements, the fixed end anchor 14 can be locked to the positioning plate 1 by the anchor locking mechanism 16; and when the horizontality of the positioning plate 1 needs to be adjusted again, the positioning plate 1 and the fixed end anchor 14 can be unlocked by the anchor locking mechanism 16. It can be understood that in other embodiments, the positioning device of the fixed end anchor of the prestressed column and the main reinforcement of the column may not include the anchor locking mechanism 16, but the fixed end anchor 14 is locked to the positioning plate 1 by an external anchor locking mechanism 16. It can be understood that in other embodiments, welding and other methods can also be used to make the positioning plate 1 and the fixed end anchor 14 non-detachably connected.
[0046] In the present embodiment, the anchor locking mechanism 16 includes a plurality of anchor locking units 16a provided on the positioning plate 1. The plurality of anchor locking units 16a are arranged at intervals around the fixed end anchor 14. Specifically, in the present embodiment, there are four anchor locking units 16a. The four anchor locking units 16a are respectively located at the four ends of the cross. In this way, it is not only convenient for the anchor locking mechanism 16 to lock or unlock the positioning plate 1 and the fixed end anchor 14, but also enables the anchor locking mechanism 16 to have the function of adjusting the verticality of the fixed end anchor 14. Specifically, in the present embodiment, the anchor locking unit 16a includes a first fixing plate 162 and a first bolt 164. The first fixing plate 162 is provided on the positioning plate 1. The first fixing plate 162 has a first threaded hole. The first bolt 164 is screwed to the first threaded hole. The first bolt 164 can move toward or away from the fixed end anchor 14 to abut or space with the fixed end anchor 14. It should be noted that, in the present embodiment, the vertical adjustment of the fixed-end anchor 14 by the anchor locking mechanism 16 is fine-tuning, and the adjustment range is very small, which is related to the gap size between the first positioning hole 3 and the fixed-end anchor 14 .
[0047] In this embodiment, if Figure 1 and Figure 4 As shown, the positioning device of the fixed end anchor of the prestressed column and the main reinforcement of the column also includes a main reinforcement locking mechanism 5. The main reinforcement locking mechanism 5 is arranged on the positioning plate 1. The main reinforcement locking mechanism 5 can lock or unlock the positioning plate 1 and the main reinforcement 15 of the column. In this way, when the horizontality of the positioning plate 1 meets the requirements, the main reinforcement 15 of the column can be locked on the positioning plate 1 through the main reinforcement locking mechanism 5; and when the horizontality of the positioning plate 1 needs to be adjusted again, the positioning plate 1 and the main reinforcement 15 of the column can be unlocked through the main reinforcement locking mechanism 5. It can be understood that in other embodiments, the positioning device of the fixed end anchor of the prestressed column and the main reinforcement of the column may not include the main reinforcement locking mechanism 5, but the main reinforcement 15 of the column is locked on the positioning plate 1 through the external main reinforcement locking mechanism 5. It can be understood that in other embodiments, welding and other methods can also be used to make the positioning plate 1 and the main reinforcement 15 of the column non-detachably connected.
[0048] In this embodiment, the main reinforcement locking mechanism 5 includes an angle steel 5a, a second fixing plate 5b and a second bolt 5c. The angle steel 5a is passed through the second positioning hole 2 and connected to the positioning plate 1. The second fixing plate 5b is passed through the positioning plate 1. The second fixing plate 5b has an upper threaded hole located on the upper side of the positioning plate 1 and a lower threaded hole located on the lower side of the positioning plate 1. The upper threaded hole and the lower threaded hole are respectively screwed with a second bolt 5c. The second bolt 5c can move toward or away from the column main reinforcement 15 to space the column main reinforcement 15 or to press the column main reinforcement 15 against the angle steel 5a. In this way, it is very convenient for the main reinforcement locking mechanism 5 to lock or unlock the positioning plate 1 and the column main reinforcement 15.
[0049] When the bottom of the fixed end anchor 14 is loose, the bottom of the fixed end anchor 14 is prone to be suspended, causing the fixed end anchor 14 to deflect, affecting the verticality of the fixed end anchor 14. In order to solve the above problem, in this embodiment, the positioning device of the fixed end anchor of the prestressed column and the main reinforcement of the column also includes a rigid bracket 11 for being arranged at the bottom of the fixed end anchor 14. The rigid bracket 11 well limits the displacement of the suspended fixed end anchor 14 relative to the bottom of the pedestal, and better ensures the verticality of the fixed end anchor 14.
[0050] In this embodiment, if Figure 1 As shown, the rigid bracket 11 includes a supporting steel bar 13 connected to the steel bar at the bottom of the cap, a steel plate 12 arranged on the supporting steel bar 13, and a plurality of angle irons 10 arranged on the steel plate 12. The plurality of angle irons 10 are arranged around the fixed end anchor 14 at intervals, and the angle irons 10 are used to be welded with the fixed end anchor 14. In this way, it is very convenient to fix the fixed end anchor 14 on the rigid bracket 11. Specifically, in this embodiment, there are four angle irons 10. The four angle irons 10 are respectively located at the four ends of the cross.
[0051] like Figure 5 As shown, the utility model also provides a method for positioning the prestressed column fixed end anchor and the column main reinforcement. The positioning method includes the following steps:
[0052] Step S1a, providing the above-mentioned positioning device for the prestressed column fixed end anchor and the column main reinforcement.
[0053] Step S1b: insert the fixed end anchor and the main reinforcement of the column into the first positioning hole and the second positioning hole of the positioning plate respectively.
[0054] Step S1c, adjusting the horizontality of the positioning plate through the adjustment mechanism.
[0055] Step S1d, detecting the horizontality of the positioning plate by means of a horizontal detection mechanism.
[0056] Step S1e, if the levelness of the positioning plate does not meet the requirement, repeat the steps of adjusting the levelness of the positioning plate by the adjusting mechanism and detecting the levelness of the positioning plate by the level detection mechanism until the levelness of the positioning plate meets the requirement.
[0057] In this embodiment, the following steps are also included before step S1b:
[0058] Step S11, a rigid bracket is arranged at the bottom of the fixed end anchor.
[0059] Step S12, setting the positioning plate at a preset position, and making the second positioning hole located above the rigid bracket. Specifically, the positioning plate can be hung at the preset position by multiple adjustment mechanisms, or by other auxiliary mechanisms.
