Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an anchor bolt positioning device. Background Technology

[0002] In building construction and industrial equipment installation, anchor bolts need to be pre-embedded in the concrete foundation of the equipment to secure the subsequent installation of equipment or steel structures. The installation accuracy of the pre-embedded anchor bolts directly determines the installation quality of the equipment and steel structures. If the accuracy is out of tolerance, subsequent installation procedures will be unable to proceed normally, and may even require rework of the foundation concrete, increasing construction costs and time.

[0003] Currently, to ensure the installation accuracy of anchor bolts, various sizes of anchor bolt positioning molds are typically custom-made according to the design drawings during construction. However, these positioning molds are directly embedded in the concrete foundation after the concrete is poured, making them impossible to remove and reuse. This not only leads to significant material waste of the positioning molds but also requires substantial labor costs to customize molds of different specifications, significantly increasing the overall construction cost and making it difficult to meet the needs of efficient and economical construction. Utility Model Content

[0004] To address the technical problems of existing anchor bolt positioning molds being unreusable and having high construction costs, this utility model provides an anchor bolt positioning device. The device aims to achieve flexible adjustment of anchor bolt specifications and installation spacing, while ensuring that the device is reusable, reducing material and labor costs, and improving the installation accuracy of anchor bolts.

[0005] The specific plan is as follows:

[0006] An anchor bolt positioning device includes four right-angle bent plates and four adjusting plates;

[0007] Each of the right-angle bent plates includes a first bent plate and a second bent plate that is perpendicularly connected to the first bent plate. A first bolt hole is provided at the corner connection between the first bent plate and the second bent plate of the right-angle bent plate, and threaded holes are provided at the ends of the first bent plate away from the corner and the ends of the second bent plate away from the corner, respectively.

[0008] The four right-angled curved plates are connected together by the four adjusting plates to form a rectangular frame structure. The inside corners of the four right-angled curved plates serve as the four corners of the rectangular frame structure, and any two adjacent right-angled curved plates are connected together by an adjusting plate.

[0009] Each of the adjusting plates has a strip-shaped through hole at both ends along its own length. The adjusting plate is fixedly connected to the right-angle bent plate by fastening bolts, and the fastening bolts pass through the strip-shaped through holes in sequence and are threadedly connected to the threaded holes; and a threaded sleeve is threadedly connected to the first bolt hole.

[0010] In some embodiments, each of the adjusting plates has a second bolt hole in the middle, and a threaded sleeve is threaded into the second bolt hole.

[0011] In some embodiments, the first bent plate and the second bent plate have the same length and width dimensions.

[0012] In some of these embodiments, the right-angled plate is a one-piece molded structure.

[0013] In some embodiments, two threaded holes are respectively opened on the front and rear sides of the first and second bending ends of each right-angled plate, and two strip-shaped through holes are respectively opened on the front and rear sides of both ends of each adjusting plate, and the positions of the two strip-shaped through holes correspond one-to-one with the two threaded holes.

[0014] In some embodiments, the threaded sleeve includes a rotating head and a threaded sleeve body fixed below the rotating head;

[0015] The outer wall of the threaded sleeve body is provided with an external thread that matches the first bolt hole or the second bolt hole, and the inner diameter of the threaded sleeve body matches the diameter of the anchor bolt to be fitted.

[0016] In some embodiments, the inner diameter of the threaded sleeve body is 0.2 to 0.3 mm larger than the diameter of the anchor bolt to be mated.

[0017] In some embodiments, both the first and second bent plates are provided with laser scale lines corresponding to the center line of the first bolt hole.

[0018] Compared with the prior art, the above-mentioned utility model has one of the following advantages or beneficial effects:

[0019] 1. Wide range of compatibility: The size of the rectangular frame can be flexibly adjusted by the combination of the strip-shaped through hole on the adjustment plate and the fastening bolt. By changing the adjustment plate, it can be adapted to more than 95% of rectangular foundation anchor bolts. Furthermore, by changing the threaded sleeve with different inner diameters, it can be adapted to various specifications of anchor bolts.

[0020] Second, it is reusable: After the anchor bolts are fixed, the positioning device can be removed for subsequent anchor bolt fixing, reducing material waste and significantly reducing the overall construction cost.

[0021] III. Functional Expansion: After being fixed, this device can be directly used for drilling and positioning of chemical bolts, expanding its application scenarios. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0032] As shown in Figures 1-6, this embodiment provides an anchor bolt positioning device, including four right-angle bent plates 1 (also called L-shaped bent plates) and four adjusting plates 2, with the specific structure as follows:

[0033] Each right-angled plate 1 is a one-piece molded structure, including a first and a second bent plate that are perpendicularly connected to each other, and both have the same length and width to ensure balanced force distribution. A first bolt hole is provided at the corner of the first and second bent plates of each right-angled plate 1, and a threaded sleeve 3 is threaded into the first bolt hole. This threaded sleeve 3 can be replaced at any time according to the diameter of the anchor bolt 11 to be fitted. Two threaded holes 4 are respectively provided at the ends of the first and second bent plates away from the corners, and the two threaded holes 4 are respectively provided on the front and rear sides of the ends of each bent plate to enhance the connection stability with the adjusting plate 2.

[0034] Four right-angled curved plates 1 are connected together by four adjusting plates 2 to form a rectangular frame structure; the inside corners of the four right-angled curved plates 1 serve as the four corners of the rectangular frame, and any two adjacent right-angled curved plates 1 are connected together by an adjusting plate 2.

[0035] Each adjusting plate 2 has two strip-shaped through holes 5 at both ends, corresponding to its own length. These two through holes 5 are located on the front and rear sides of each adjusting plate 2 end, respectively. The positions of these two through holes correspond one-to-one with the two threaded holes 4 at the end of the right-angled plate 1. The adjusting plate 2 is fixedly connected to the right-angled plate 1 by fastening bolts 7, which pass through the strip-shaped through holes and are threaded into the threaded holes 4. The spacing between adjacent right-angled plates 1 can be adjusted through the strip-shaped through holes 5, thereby adjusting the size of the rectangular frame to accommodate rectangular foundation anchor bolts of different sizes. A threaded sleeve 3 is threaded into the first bolt hole. Each adjusting plate 2 has a second bolt hole in its middle, with a threaded sleeve 3 threaded into the second bolt hole to meet the positioning requirements of multiple anchor bolts. Of course, in some cases, such as... Figure 5 As shown, the second bolt holes can also be opened only on some of the adjusting plates 2, depending on the actual needs. Figure 5 In the middle, the length of the two adjustment plates 2 set at the front and back is longer than the length of the two adjustment plates 2 set on the left and right, thus forming a rectangular frame structure, which is therefore suitable for anchor bolts on rectangular foundations.

[0036] The aforementioned threaded sleeve 3 includes a rotating head 31 and a threaded sleeve body 32 fixed below it; the outer wall of the threaded sleeve body 3 is provided with an external thread, and the external thread of the threaded sleeve body 32 is adapted to the internal thread of the bolt hole (first bolt hole / second bolt hole); the inner diameter of the threaded sleeve body 32 is adapted to the diameter of the anchor bolt 11 to be installed, and the inner diameter is 0.2 to 0.3 mm larger than the diameter of the anchor bolt 11, which facilitates the insertion of the anchor bolt 11 and avoids excessive offset.

[0037] The first and second curved plates are equipped with laser scale lines 6, which correspond to the center line of the first bolt hole, to help quickly calibrate the installation position of the anchor bolts and improve positioning accuracy.

[0038] like Figure 7 As shown, the positioning device can be placed in a storage box when not in use, and the storage box is also equipped with threaded sleeves 3 of various specifications to adapt to the positioning and installation of various anchor bolt specifications.

[0039] The following is a detailed description of the manufacturing, assembly, installation, and usage methods of the positioning device in this application!

[0040] Step S1: Fabricate the components of the anchor bolt positioning device according to the drawings:

[0041] Specifically, the components are first manufactured. According to the drawings, a right-angled plate 1 and an adjusting plate 2 can be processed using a steel plate with a thickness of 10-16mm. The first bolt hole is processed at the corner of the right-angled plate 1, and the threaded hole 4 is processed at the end. Strip-shaped through holes are formed at both ends of the adjusting plate 2 (the second bolt hole is drilled in the middle as needed), and laser scale lines 6 are engraved on the right-angled plate 1.

[0042] Step S2, assemble the device: According to the installation spacing of the anchor bolts 11, use fastening bolts 7 to connect the right-angle bent plate 1 and the adjusting plate 2 to form a rectangular frame. After adjusting the size, tighten the fastening bolts 7. Then, according to the diameter of the anchor bolts 11, select a threaded sleeve 3 with an inner diameter 0.2mm larger than the diameter of the anchor bolts and screw it into the first bolt hole (and the second bolt hole, if multiple positioning is required).

[0043] Step S3, anchor bolt positioning: Place the positioning device above the foundation reinforcement 9, with channel steel or square steel at the bottom, insert the anchor bolt 11 into the threaded sleeve 3, and use the shim to adjust the positioning device to a horizontal state. Adjust the positioning device according to the laser scale line 6 until the front, back, left and right centers of the anchor bolt meet the requirements of the drawing. Adjust the top elevation of the anchor bolt 11 to the height required by the drawing by rotating the nut 10. The channel steel or square steel and the shim together form the support structure 8.

[0044] Step S4, Fixing and Removal: Use angle steel to weld and fix the anchor bolt 11 to the foundation steel bar 9, loosen the nut 10 to remove the positioning device, and install the anchor bolt protective sleeve to protect the threads of the anchor bolt 11.

[0045] Step S5: Install and position the next set of anchor bolts. After completion, place the positioning device into the storage box. This embodiment can also be used for chemical bolt installation. Specifically, the rectangular frame is fixed to the construction surface, and the use of threaded sleeves greatly improves the installation accuracy of the chemical bolts and enhances the quality of equipment installation.
