Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a positioning mold for tower crane anchor bolts. Background Technology

[0002] Anchor bolts are key connecting components in building construction and machinery installation, used to firmly fix equipment or structures to concrete foundations to ensure their stability.

[0003] In tower crane installation, anchor bolts are the core components that ensure a firm connection between the tower crane foundation and the concrete structure. The existing anchor bolt installation process involves first excavating an installation trench on the construction surface, then setting up a positioning mold in the trench. The anchor bolt passes vertically through the positioning mold, and then concrete or cement mortar is poured onto the construction surface to fix the bottom of the anchor bolt. The positioning mold is then removed, and the tower crane is hoisted and inserted into the anchor bolt for further fixation.

[0004] Regarding the aforementioned technologies, the stability of the current positioning mold is poor. During concrete pouring, the anchor bolts are prone to shaking, causing deviations in the verticality of the anchor bolts. Utility Model Content

[0005] To improve the stability of anchor bolts, this application provides a tower crane anchor bolt positioning mold.

[0006] The technical solution for a tower crane anchor bolt positioning mold provided in this application is as follows:

[0007] A tower crane anchor bolt positioning mold includes a fixed rod erected on an installation groove, a positioning template set on the top of the fixed rod, and a locking assembly set on the positioning template for fixing the anchor bolt. The locking assembly includes a guide sleeve detachably set at the bottom of the positioning template and a locking element for fixing the guide sleeve.

[0008] By adopting the above technical solution, the positioning mold is stably erected on the installation groove, and the anchor bolts are fixed by the positioning template and locking components to prevent the anchor bolts from shaking when pouring concrete and to ensure their verticality. At the same time, the guide sleeve is designed for easy operation and replacement.

[0009] Optionally, an installation gap is formed between the opening of the fixed rod and the mounting groove for installing the guide sleeve, and the length of the guide sleeve is less than the installation gap.

[0010] By adopting the above technical solution, contact between the guide sleeve and the installation groove is avoided, reducing the impact on the guide sleeve during concrete pouring.

[0011] Optionally, a locking element that abuts against the anchor bolt is slidably installed inside the guide sleeve, and a drive rod that drives the locking element to slide and unlock is provided outside the guide sleeve.

[0012] By adopting the above technical solution, the locking component inside the guide sleeve can slide and abut against the anchor bolt, thereby effectively fixing the anchor bolt, improving the stability of the anchor bolt during the concrete pouring process, and reducing shaking and verticality deviation; the drive rod outside the guide sleeve can drive the locking component to slide and unlock, making it convenient to unlock and lock the locking component.

[0014] By adopting the above technical solution, multiple sets of locking arc plates at the end of the locking collar are used, and there is a deformation gap between adjacent arc plates. The first inclined surface abuts against the guide sleeve, which can more effectively hold the anchor bolt, improve the fixing stability of the anchor bolt, and reduce its shaking and verticality deviation when pouring concrete.

[0015] Optionally, the guide sleeve is provided with a locking groove for the locking collar to slide, and the guide sleeve is provided with a reset elastic element connecting the locking collar in the locking groove.

[0016] By adopting the above technical solution, the locking collar can slide stably in the guide sleeve and can return to its initial position by relying on the reset elastic element after the force changes, which is convenient to use.

[0017] Optionally, the outer wall of the guide sleeve is provided with a drive groove that communicates with the locking groove and provides space for the drive rod, and the drive rod passes through the drive groove and is fixedly connected to the locking collar.

[0018] By adopting the above technical solution, it is convenient for the drive rod to operate on the outside of the guide sleeve, so that the drive rod can drive the locking collar to slide smoothly in the locking groove, thereby realizing the locking and unlocking control of the anchor bolts.

[0019] Optionally, the drive rod includes a connecting part that connects to the guide sleeve and a rotating part that is hinged to the connecting part, and the outer wall of the guide sleeve is provided with a snap ring for the rotating part to engage.

[0020] By adopting the above technical solution, the connecting part of the drive rod is connected to the guide sleeve, the rotating part is hinged to the connecting part and can be engaged with the snap ring on the outer wall of the guide sleeve, which makes it easy for the locking part to be kept in the locked state.

[0021] Optionally, the top of the guide sleeve is provided with an insertion arc piece, and the positioning template has an insertion through hole for the insertion arc piece to pass through. The circumferential arc length of the insertion through hole is greater than the circumferential arc length of the insertion arc piece, and the insertion arc piece is provided with an erection part for mounting on the positioning template.

[0022] By adopting the above technical solution, it is convenient to install and disassemble the guide sleeve and the positioning template, and the installation position of the guide sleeve can be initially positioned.

[0023] Optionally, the locking element is a locking bolt, the erection part has a locking through hole for the locking element to pass through, and the positioning template has a locking screw hole that cooperates with the locking element.

[0024] By adopting the above technical solution, it is convenient to install and disassemble the guide sleeve and the positioning template, and the installation position of the guide sleeve can be initially positioned.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The positioning mold, through the fixed rod, positioning template and locking components, can be stably erected on the installation groove to prevent the anchor bolts from shaking when pouring concrete;

[0027] 2. By setting the reset elastic element, the locking element can return to its initial position after the force changes;

[0028] 3. The rotating part and the snap ring ensure that the locking part is always kept in the locked state, improving the stability during watering. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a tower crane anchor bolt positioning mold.

[0037] Reference Figure 1 A tower crane anchor bolt positioning mold includes a fixed rod 1 erected on the installation groove 5, a positioning template 2 set on the top of the fixed rod 1, and a locking component 3 set on the fixed template for locking the anchor bolt 4.

[0038] Reference Figure 1 and Figure 2 The fixing rod 1 comprises two sets of parallel rectangular plates, the length of which is greater than the length of the mounting groove 5, allowing the fixing rod 1 to be erected on the top of the construction surface. The positioning template 2 is erected on top of the fixing rod 1, and an installation gap 11 is formed between the fixing rod 1 and the opening of the mounting groove.

[0039] The fixed rod 1 is also provided with extension plates at both ends and extension rods 13 vertically set on the top of the extension plates. The extension plates are arranged horizontally, and counterweights 14 are inserted into the extension rods 13. The counterweights 14 increase the overall weight of the fixed rod 1 and improve the overall stability of the positioning mold during glue dispensing.

[0040] Refer to and Figure 3 The positioning template 2 is a rectangular metal plate with mounting parts 21 on both sides that are attached to the fixed rod 1. The mounting parts 21 are equipped with bolts for fixing to the fixed rod 1. Each of the four corners of the positioning template 2 has a through hole 22 that passes through both end faces and allows the anchor bolts 4 to pass through. The inner diameter of the through hole 22 is larger than the outer diameter of the anchor bolt 4.

[0041] The locking assembly 3 includes a guide sleeve 31 disposed at the bottom of the positioning template 2 and a locking element 32 for locking the guide sleeve 31. The guide sleeve 31 corresponds one-to-one with the mounting through hole 22. Two sets of insertable arc plates 311 are provided on the top of the guide sleeve 31, and the two sets of insertable arc plates 311 are symmetrically arranged along the axis of the guide sleeve 31. The length of the guide sleeve 31 is less than the installation gap 11, so that the bottom of the guide sleeve 31 does not contact the concrete in the mounting groove 5, improving assembly and disassembly efficiency.

[0042] The positioning template 2 has an insertion through hole 23 on the outside of the mounting through hole 22 for the insertion arc piece 311 to pass through. The circumferential arc length of the insertion through hole 23 is greater than the circumferential arc length of the insertion arc piece 311, so that the insertion arc piece 311 can rotate a certain angle after being inserted into the insertion through hole 23. The end of the insertion arc piece 311 is provided with an erection part 3111 for mounting on the top of the positioning template 2. The locking member 32 is a locking bolt. The erection part 3111 has a locking through hole 3112 for the locking member 32 to pass through. The positioning template 2 has a locking screw hole 24 that mates with the locking member 32. When installing the guide sleeve 31, insert the guide sleeve 31 from the bottom upwards, insert the arc plate 311 through the insertion through hole 23, and then rotate the guide sleeve 31 circumferentially so that the erection part 3111 is erected on the top of the positioning template 2. At the same time, the locking screw hole 24 and the locking through hole 3112 correspond, and the guide sleeve 31 and the positioning template 2 are fixed by the locking bolt.

[0043] A locking element 33 for locking the anchor bolt 4 is slidably installed inside the guide sleeve 31, and a drive rod 34 for driving the locking element 33 to slide is provided on the outside of the guide sleeve 31.

[0044] Reference Figure 3 , Figure 4 and Figure 5 The locking component 33 is generally circular, comprising a locking collar 331 and at least three sets of locking arc plates 332 disposed at the ends of the locking collar 331. In this embodiment, the locking component 33 includes three sets of locking arc plates 332, which are evenly spaced circumferentially along the axis of the locking collar 331. Adjacent locking arc plates 332 have deformation gaps 333 between them. The outer diameter of the locking arc plate 332 is larger than the outer diameter of the locking collar 331, and the outer wall of the connection between the locking arc plate 332 and the locking sleeve is provided with a first inclined surface 334 for abutting against the guide sleeve 31. The guide sleeve 31 has a second inclined surface 312 that cooperates with the abutting inclined surface. Through the abutting cooperation of the first inclined surface 334 and the second inclined surface 312, when the locking member 33 moves upward, the locking arc plate 332 tilts inward toward the axis, so that the inner control of the locking arc plate 332 gradually shrinks, thereby achieving the locking effect on the anchor bolt 4.

[0045] The guide sleeve 31 has a locking groove 313 along its axial direction on its inner wall, and a locking ring 331 has a locking ring portion 3311 that is positioned within the locking groove 313. A reset elastic element 314 is provided within the locking groove 313 of the guide sleeve 31, with its two ends fixed to the inner top wall of the locking groove 313 and the top of the locking ring portion 3311, respectively. The guide sleeve 31 is composed of two sets of semi-circular arc plates joined together to facilitate the installation of the locking element 32 and the guide sleeve 31.

[0046] The drive rod 34 is used to realize the vertical movement of the locking member 33. The drive rod 34 includes a connecting part 341 and a rotating part 342. The outer wall of the guide sleeve 31 has a drive groove 315 communicating with the locking groove 313. The drive groove 315 is arranged along the axial direction of the guide sleeve 31. The connecting part 341 and the outer wall of the locking ring part 3311 are fixedly connected.

[0047] The rotating part 342 is hinged to the end of the connecting part 341 away from the drive slide groove 315, and the end of the rotating part 342 is provided with a snap hook 3421. The outer side wall of the guide sleeve 31 is provided with a snap ring 316 for the rotating part 342 to rotate into. The top of the snap ring 316 has a snap groove that mates with the snap hook 3421.

[0048] The implementation principle of the tower crane anchor bolt positioning mold in this application embodiment is as follows: the fixed rod 1 is positioned on the top of the installation groove 5, the assembled positioning template 2 and locking component 3 are erected on the fixed rod 1 and the positioning template 2 is fixed, then the anchor bolt 4 is inserted into the anchor through hole of the positioning template 2, the drive rod 34 is pulled upward so that the locking arc plate 332 locks the anchor bolt 4, and then the rotating part 342 is driven so that the snap hook 3421 is engaged in the snap groove of the snap ring 316, thereby realizing the positioning of the locking component 33 and ensuring the verticality of the anchor bolt 4 during pouring.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
