Description

Technical Field

[0001] This application relates to the technical field of outsourcing column bases, and in particular to a reusable bolt positioning device. Background Art

[0002] With the country's strong promotion of prefabricated buildings, steel structure components are constantly innovating. The key parts affecting the safety of steel structures mainly lie in beam-column joints and column base joints. Over the years, the degree of attention paid to column base joints has been far less than that of beam-column joints, which makes the innovative development of column base joint structures extremely urgent. The installation quality of steel column bases will directly affect the transfer of the upper steel frame load. The upper load is transferred to the foundation through the steel column and the column base. As a key node in this process, the installation quality of the connection node between the steel column and the foundation will directly affect the safety of the steel frame structure. At present, the main column base forms of steel structure components include exposed type, outsourcing type, embedded type, and inserted type. Among them, for the column base form of large industrial plants, the outsourcing column base form is generally adopted. The outsourcing column base has the characteristics of excellent connection performance and convenient construction, which is conducive to prefabricated construction. In the construction of the connection node between the steel column and the foundation, a bolt positioning device is mainly used. The positioning bolts are pre-embedded and connected to the column base plate, and then stirrups are tied around it to achieve high-quality connection between the steel column base and the pile cap through secondary pouring. From the above description, it can also be found that the installation quality control of the pre-embedded bolts is the key to affecting the force transmission of the entire column base and pile cap system.

[0003] At present, in bolt positioning construction, auxiliary fixing measures such as anchor bolt positioning brackets and positioning plates are often used to ensure the accuracy of bolt positioning. In the current bolt positioning construction, the positioning plate is often poured into the connection node along with the installation of the steel column. This often causes waste of resources and does not conform to the concept of green construction. Utility Model Content

[0004] In order to facilitate the repeated use of the positioning device, this application provides a reusable bolt positioning device.

[0005] A reusable bolt positioning device provided by this application adopts the following technical solutions:

[0006] A reusable bolt positioning device includes multiple groups of support blocks arranged on the cushion layer, and a positioning plate arranged on the multiple groups of support blocks. The positioning plate is used to lock the positions of multiple groups of pre-embedded positioning bolts. An adjusting component for adjusting the positions of the pre-embedded positioning bolts is arranged on the positioning plate, and the adjusting component can detachably separate the positioning plate from the pre-embedded positioning bolts.

[0007] By adopting the above technical solution, the supporting block supports and positions the positioning plate, the positioning plate positions the installation positions of multiple groups of embedded positioning bolts, locks and fixes the embedded positioning bolts on the positioning plate, and then adjusts the positions of the embedded positioning bolts on the positioning plate through the adjusting assembly. After the casting and solidification of the bearing platform column are completed, the positions of the embedded positioning bolts on the positioning plate are adjusted through the adjusting assembly, so as to facilitate the removal of the positioning plate and the adjusting assembly, and facilitate the repeated use of the positioning device.

[0008] Furthermore, positioning holes are formed in the positioning plate to facilitate the passing of the embedded positioning bolts through, and the adjusting assembly includes:

[0009] A supporting nut, which is threadedly arranged on the embedded positioning bolt and supports the bottom of the positioning plate;

[0010] A tightening nut, which is threadedly arranged on the embedded positioning bolt and tightens one end of the positioning plate away from the supporting nut. The positions of the embedded positioning bolts on the positioning plate are adjusted by adjusting the positions of the supporting nut and the tightening nut on the embedded positioning bolt.

[0011] By adopting the above technical solution, the supporting nut and the tightening nut respectively abut against the opposite ends of the positioning plate, so as to lock the embedded positioning bolt on the positioning plate. At the same time, the positions of the supporting nut and the tightening nut on the embedded positioning bolt are adjusted to adjust the positional relationship between the embedded positioning bolt and the positioning plate.

[0012] Furthermore, a through hole is formed in the middle of the positioning plate, and the through hole facilitates the casting of the bearing platform column.

[0013] By adopting the above technical solution, when casting the bearing platform column, the through hole facilitates the real-time monitoring of the casting process of the bearing platform column, and at the same time, concrete can be injected into the bearing platform column through the through hole.

[0014] Furthermore, two groups of positioning steel bars perpendicular to the plane of the vertical wall are arranged on the side walls of the positioning plate. The two groups of positioning steel bars are respectively close to the two ends of the side wall length direction of the positioning plate, and the positioning steel bars are used to judge the installation accuracy of the embedded positioning bolts.

[0015] By adopting the above technical solution, when it is necessary to accurately measure the position of the positioning plate, the positions of the protruding positioning steel bars are measured, and the installation accuracy of the embedded positioning bolts can be quickly measured.

[0016] Furthermore, a backing plate is arranged on the positioning plate to increase the contact area between the supporting nut or the tightening nut and the positioning plate.

[0017] By adopting the above technical solution, the supporting nut or the tightening nut contacts the positioning plate through the backing plate, increasing the contact area with the positioning plate and thereby reducing the pressure on the positioning plate.

[0018] Further, a protective cover for protecting the adjusting assembly is sleeved on the embedded positioning bolt, and the protective cover abuts against the backing plate and prevents sundries from entering the adjusting assembly.

[0019] By adopting the above technical solution, the protective cover is sleeved on the embedded positioning bolt to protect the connection between the tightening nut and the embedded positioning bolt, facilitating the subsequent removal of the tightening nut.

[0020] Further, a circular ring platform for increasing the contact area with the positioning plate is provided on one side of the supporting nut close to the positioning plate. A positioning sleeve coaxial with the supporting nut is provided on the circular ring platform, and the positioning sleeve is in snap-fit connection with the positioning hole.

[0021] By adopting the above technical solution, when the supporting nut is threadedly installed on the embedded positioning bolt, the bottom of the positioning plate is supported by the circular ring platform, and the positioning sleeve is used for snap-fit connection with the positioning hole, thereby improving the coaxiality between the embedded positioning bolt and the positioning hole and facilitating the accurate positioning of the multi-group embedded positioning bolts by the positioning plate.

[0022] Further, a guiding arc surface for facilitating the insertion of the positioning sleeve into the positioning hole is provided at one end of the positioning sleeve away from the circular ring platform.

[0023] By adopting the above technical solution, the guiding arc surface guides the positioning plate hole, thereby facilitating the rapid sliding of the positioning sleeve into the positioning hole.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The positioning plate is supported and positioned by the support block, and the installation positions of the multi-group embedded positioning bolts are positioned by the positioning plate.

After the casting of the bearing platform column is completed and solidified, the positions of the supporting nut and the locking nut on the embedded positioning bolt are adjusted to facilitate the removal of the positioning plate, the supporting nut and the locking nut, and facilitate the repeated use of the positioning device.

[0026] 2. The embedded positioning bolts are locked on the positioning plate by the tightening nut and the supporting nut. After the installation position of the embedded positioning bolt is adjusted, the protective cover is sleeved on the embedded positioning bolt to protect the connection between the tightening nut and the embedded positioning bolt, facilitating the subsequent removal of the tightening nut.

[0027] 3. Increase the contact area with the positioning plate through the circular ring platform on the supporting nut, and engage the positioning sleeve with the positioning hole to improve the coaxiality between the embedded positioning bolt and the positioning hole, facilitating the accurate positioning of multiple groups of embedded positioning bolts by the positioning plate.

Detailed Description of the Embodiments

[0034] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0035] The embodiments of the present application disclose a reusable bolt positioning device.

[0036] Embodiment 1

[0037] Referring to Figure 1 , a reusable bolt positioning device includes multiple groups of supporting blocks 1 arranged on the cushion layer, a positioning plate 2 arranged on the multiple groups of supporting blocks 1, the positioning plate 2 is used to lock the positions of multiple groups of embedded positioning bolts 8, and an adjusting assembly 3 for adjusting the positions of the embedded positioning bolts 8 is arranged on the positioning plate 2, and the adjusting assembly 3 can detachably separate the positioning plate 2 from the embedded positioning bolts 8.

[0038] Referring to Figure 1 and Figure 2, the positioning plate 2 is initially fixed on the cushion layer by multiple support blocks 1. The positioning plate 2 is provided with positioning holes 22 facilitating the penetration of the embedded positioning bolts 8. After the embedded positioning bolts 8 penetrate through the positioning plate 2, the position of the embedded positioning bolts 8 is adjusted by the adjusting assembly 3. The adjusting assembly 3 includes a support nut 31 and a tightening nut 32. The support nut 31 is threadedly installed on the embedded positioning bolt 8, and by rotating the support nut 31, the position of the support nut 31 on the embedded positioning bolt 8 is adjusted.

[0039] Refer to Figure 1 and Figure 2 , a backing plate 4 is sleeved and installed on the embedded positioning bolt 8. The backing plate 4 passes through the embedded positioning bolt 8 and abuts against the support nut 31. After the support nuts 31 and the backing plates 4 on multiple groups of embedded positioning bolts 8 are all installed, the multiple groups of positioning holes 22 on the positioning plate 2 are respectively matched with the multiple groups of embedded positioning bolts 8, thereby placing the positioning plate 2 on the multiple support blocks 1. At the same time, the support nut 31 is located on the lower surface of the positioning plate 2 and contacts the positioning plate 2 through the backing plate 4. After the positioning plate 2 is installed, a baffle is installed through the embedded positioning bolt 8 and the baffle is made to abut against the upper surface of the positioning plate 2. Then the tightening nut 32 is threadedly installed on the embedded positioning bolt 8, and finally the tightening nut 32 abuts against the upper surface of the positioning plate 2 through the baffle. The upper and lower end faces of the positioning plate 2 are tightly fixed by the tightening nut 32 and the support nut 31 together, thereby locking the embedded positioning bolt 8 on the positioning plate 2.

[0040] Refer to Figure 1 , a through hole 21 is provided in the middle of the positioning plate 2. The self-weight of the positioning plate 2 is reduced by the provided through hole 21. When pouring concrete for the bearing platform column, the through hole 21 facilitates the entry of concrete and also facilitates the observation of the pouring situation, thereby facilitating the pouring of the bearing platform column.

[0041] Refer to Figure 1 , two groups of positioning steel bars 23 are arranged on the side walls of the positioning plate 2. The positioning plate 2 is a rectangular plate structure. The through hole 21 is a square hole and is located in the middle of the positioning plate 2. The positioning plate 2 has four side walls, and two groups of positioning steel bars 23 are installed on each side wall. The axis of the positioning steel bar 23 is perpendicular to the plane where the corresponding side wall is located. The two groups of positioning steel bars 23 are respectively close to both ends of the side wall length direction of the positioning plate 2, thereby making the distance between the two groups of positioning steel bars 23 on the same end face of the positioning plate 2 larger, facilitating the detection of the installation accuracy of the positioning plate 2. By measuring the position of the positioning steel bar 23 on each side, the installation accuracy of the embedded positioning bolt 8 is judged. When the installation accuracy of each side of the positioning plate 2 meets the requirements, the installation accuracy of the overall embedded positioning bolt 8 is satisfied.

[0042] Refer to Figure 1 andFigure 2 During construction, the pile foundation is constructed first. After the pile foundation construction is completed, the cushion layer above the pile foundation is cleaned first. The steel bar cage of the pile cap column is tied on the cushion layer. Then, the embedded positioning bolts 8 are preliminarily placed on the steel bar cage. The supporting nuts 31 are installed at the designated positions of the embedded positioning bolts 8. The backing plates 4 are installed on the upper surfaces of the supporting nuts 31. Then, the positioning plates 2 are installed on multiple groups of supporting blocks 1. Another group of baffles is passed through the embedded positioning bolts 8 and abutted against the upper surfaces of the positioning plates 2. The tightening nuts 32 are installed on the embedded positioning bolts 8 and abutted against the upper surfaces of the positioning plates 2 through the baffles, so as to fixedly install the embedded positioning bolts 8 on the positioning plates 2. The positions of the positioning plates 2 are determined by measuring the positions of multiple groups of positioning steel bars 23. Finally, the anchoring length, exposed length, and plane positioning of the embedded positioning bolts 8 in the foundation are measured. When the positions of the embedded positioning bolts 8 all meet the design requirements, concrete is poured to the designated design elevation.

[0043] Refer to Figure 1 After the concrete reaches the design strength, the tightening nuts 32 and the baffles are removed, and then the positioning plates 2 are taken out. Finally, the supporting nuts 31 are taken out to facilitate the reuse of the positioning plates 2, tightening nuts 32, baffles, and supporting nuts 31 next time.

[0044] Refer to Figure 1 After the positioning device is taken out, the next step is to hoist and adjust the elevation of the steel column. The steel column is locked on the embedded positioning bolts 8 through nuts for fixation. After tying the steel bars, it is integrally formed by secondary pouring.

[0045] The working principle of Embodiment 1 of this application is as follows:

[0046] The positioning plate 2 is supported and positioned by the supporting blocks 1. The installation positions of multiple groups of embedded positioning bolts 8 are positioned by the positioning plates 2. The embedded positioning bolts 8 are locked and fixed on the positioning plates 2 through the supporting nuts 31 and the locking nuts. Then, the positions of the supporting nuts 31 and the locking nuts on the embedded positioning bolts 8 are adjusted to adjust the positions of the embedded positioning bolts ⑧. After the pile cap column is poured and solidified, the positions of the supporting nuts 31 and the locking nuts on the embedded positioning bolts 8 are adjusted to facilitate the removal of the positioning plates 2, supporting nuts 31, and locking nuts, facilitating the multiple reuse of the positioning device.

[0047] Embodiment 2

[0048] Refer to Figure 3, the difference between this embodiment and Embodiment 1 is that a protective cover 5 is sleeved on the embedded positioning bolt 8. After the position of the embedded positioning bolt 8 on the positioning plate 2 is adjusted, the protective cover 5 is sleeved on the embedded positioning bolt 8. The protective cover 5 is of a cylindrical structure, and the bottom of the protective cover 5 abuts against the upper surface of the baffle 4. The protective cover 5 wraps the tightening nut 32 on the baffle 4, reducing the probability of sundries in the poured concrete of the bearing platform column sticking to the tightening nut 32, and at the same time reducing the probability of concrete entering the gap between the positioning hole 22 and the embedded positioning bolt 8, facilitating the subsequent removal of the tightening nut 32, and facilitating the multiple use of the tightening nut 32 and the positioning plate 2.

[0049] The working principle of Embodiment 2 of this application is as follows:

[0050] The embedded positioning bolt 8 is locked on the positioning plate 2 by the tightening nut 32 and the supporting nut 31. After the installation position of the embedded positioning bolt 8 is adjusted, the protective cover 5 is sleeved on the embedded positioning bolt 8 to protect the connection between the tightening nut 32 and the embedded positioning bolt 8, facilitating the subsequent removal of the tightening nut 32.

[0051] Embodiment 3

[0052] Refer to Figure 4 and Figure 5 , the difference between this embodiment and Embodiment 1 is that a ring platform 6 for increasing the contact area with the positioning plate 2 is provided on the side of the supporting nut 31 close to the positioning plate 2. A positioning sleeve 7 is provided at one end of the ring platform 6 away from the supporting nut 31. The axis of the positioning sleeve 7 coincides with the axis of the supporting nut 31. The positioning sleeve 7 is in snap-fit with the positioning hole 22, reducing the clearance between the positioning sleeve 7 and the positioning hole 22, and thus improving the positioning effect of the positioning plate 2 on the embedded positioning bolt 8.

[0053] Refer to Figure 4 and Figure 5 , in order to facilitate the insertion of the positioning sleeve 7 into the positioning hole 22, a guiding arc surface for facilitating the insertion of the positioning sleeve 7 into the positioning hole 22 is provided at one end of the positioning sleeve 7 away from the ring platform 6; at the same time, the tightening nut 32 and the supporting nut 31 are symmetrical to each other to improve the coaxiality of the embedded positioning bolt 8 and the positioning hole 22, but the length of the positioning sleeve 7 on the tightening nut 32 is shorter, only assisting the positioning sleeve 7 on the supporting nut 31.

[0054] Refer to Figure 4 and Figure 5, during installation, first threadedly install the support nut 31 with the annular table 6 at the specified position on the embedded positioning bolt 8, then cooperate the multiple groups of positioning holes 22 on the positioning plate 2 with the multiple groups of embedded positioning bolts 8, and through the guiding of the guiding arc surface, make the positioning sleeve 7 and the positioning holes 22 engage with each other, and the bottom of the positioning plate 2 abuts tightly against the annular table 6. Finally, threadedly install the tightening nut 32 on the embedded positioning bolt 8 and abut it against the positioning plate 2, thereby improving the coaxiality between the embedded positioning bolt 8 and the positioning holes 22 and facilitating the accurate positioning of the multiple groups of embedded positioning bolts 8 by the positioning plate 2.

[0055] The working principle of Embodiment 3 of this application is as follows:

[0056] The support nut 31 increases the contact area with the positioning plate 2 through the annular table 6, and through the engagement of the positioning sleeve 7 and the positioning holes 22 with each other, thereby improving the coaxiality between the embedded positioning bolt 8 and the positioning holes 22 and facilitating the accurate positioning of the multiple groups of embedded positioning bolts 8 by the positioning plate 2.

[0057] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
