[0021] The following describes embodiments of the present invention in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments of the invention, rather than all the embodiments.

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0023] The embodiments described below with reference to the accompanying drawings are illustrative and intended only to explain the present invention and are not to be construed as limiting the present invention. In describing the present invention, it should be understood that terms such as "install," "connect," and "fix" are to be understood broadly, encompassing both direct and indirect connection, installation, or fixation, and the present invention is not intended to limit these terms.

[0024] like Figures 1 to 3 As shown, a schematic diagram of an embodiment of an embedded bolt positioning device of the present invention includes a support frame, the support frame includes a bracket body, a positioning plate 1 that can be connected to the embedded bolts and a clamp for fixing, the clamp is slidably connected to the bracket body, and the positioning plate 1 is slidably connected to the bracket body.

[0025] In this embodiment, the bracket body includes two relatively parallel guide rods 2. A positioning plate 1 is penetrated by bolt locating holes 11. Both sides of the positioning plate 1 have sleeve portions 12 that slidably engage with the corresponding guide rods 2. The sleeve portions 12 can match the cross-section of the corresponding guide rods 2. The positioning plate 1 is a bent steel plate with a hole in the center to form the bolt locating hole 11. The edges of the two sides are bent to form tubular sleeve portions 12 that can be sleeved over the corresponding guide rods 2. The guide rods 2 can be made of steel bars.

[0026] In this embodiment, the clamp includes two sleeves 3 and a fixing member 4. The two sleeves 3 are slidably connected to the corresponding guide rods 2. Both sleeves 3 are connected to the fixing member 4, which is used to clamp to the edge of the template. Preferably, the fixing member 4 is an inverted U-shaped clip, with its top connected to the corresponding two sleeves 3 and the opening facing downward to form a template clamping space.

[0027] In this embodiment, the bracket body also includes an anti-slip block 5, and the two guide rods 2 are respectively connected to the anti-slip block 5 to form an end closed structure. Preferably, each bracket body includes two anti-slip blocks 5, and the two ends of each anti-slip block 5 are respectively connected to the same side ends of the two guide rods 2, and the two ends of each guide rod 2 are connected to a corresponding anti-slip block 5 to form a closed rectangular frame. Each support frame includes two clamps to respectively fix the two ends of the guide rod 2. The anti-slip block 5 can better prevent the clamp from slipping during the sliding adjustment process. The positioning plate 1 is arranged between the two clamps.

[0028] When there are multiple support frames for combined use, each support frame can form any of the following layouts: relatively parallel arrangement, orthogonal arrangement, or connected to form a polygonal adjustable frame.

[0029] The embedded bolt positioning device also includes a matching number of connection structures, and each supporting frame is slidably connected to each other through the corresponding connection structures.

[0030] When the number of the supporting frames is three or more, two of them may be arranged parallel to each other and orthogonal to the remaining supporting frames, and the connecting structure is arranged at the orthogonal intersection node.

[0031] In this embodiment, there are four support frames, which are connected to form an adjustable rectangular support frame.

[0032] In this embodiment, the connection structure includes at least one connector, and the connector includes two connecting pipes 6 connected perpendicularly to each other. Each connecting pipe 6 is slidably connected to the corresponding bracket body. Specifically, the connecting pipe 6 is slidably connected to the corresponding guide rod 2. In this embodiment, the two guide rods 2 connected by the connector can be adjusted in four directions, and the adjustment is flexible and convenient. Each connection structure includes three connectors, which form a stable planar structure with the corresponding two support frames through three-point positioning, avoid torsional deformation during the use of the structure, improve the connection strength, better resist the impact of subsequent concrete pouring, ensure the accurate positioning and fixing stability of the embedded bolts, and avoid the embedded bolts from tipping over or shifting during the fixing process; the three connectors can also ensure the smoothness of the sliding adjustment and ensure construction efficiency.

[0033] In one embodiment, the bracket body is provided with scale lines to facilitate the positioning and adjustment of the embedded bolts; in this embodiment, the positioning plate 1 is also provided with scale lines to further improve positioning accuracy, forming a dual-precision positioning system. Preferably, the scale lines on the bracket body are provided on the guide rod 2, with the zero mark set in the middle of the guide rod 2 and the scale lines increasing in size from the middle to the ends.

[0034] On the other hand, the present invention also provides a construction method of the embedded bolt positioning device, comprising the following steps:

[0035] Place the bracket body on the template and fix it with a clamp, install the embedded bolts on the positioning plate 1 and adjust the positioning plate 1 to the target position.

[0036] The specific construction process of this embodiment is as follows:

[0037] First, select the number and arrangement of support frames according to construction requirements, assemble the appropriate number of support frames through the corresponding connecting structure, and finally connect the same-direction ends of the two guide rods 2 of each bracket body through the anti-slip stopper 5 to form a closed rectangle to prevent the clamp, connecting structure and positioning plate 1 from slipping.

[0038] Use the total station to determine the cross line for installing the embedded bolts on the foundation and mark it on the template.

[0039] According to the actual template spacing, embedded bolt positioning requirements, etc., the relative positions of multiple bracket bodies are adjusted by sliding, so that the zero scale line on the guide rod 2 is aligned with the embedded bolt positioning center line marked on the template, and the clamp is slid on the bracket body to fix the fixing part 4 to the top edge of the corresponding template. According to the embedded bolt positioning requirements, the position of the positioning plate 1 is adjusted by sliding along the guide rod 2, the hole spacing of adjacent bolt positioning holes 11 is adjusted, the embedded bolts are inserted into the bolt positioning holes 11, and the nuts 7 are placed above the positioning plate 1 and connected with the threads on the surface of the embedded bolts. The nuts 7 can not only fix the embedded bolts to the positioning plate 1, but also fix the length of the embedded bolt top extending out of the positioning plate 1. Use a level to check the length of the embedded bolt top extending out of the positioning plate 1. When the extended length does not meet the requirements, adjust the corresponding nut 7 so that the length of the embedded bolt top extending out of the positioning plate 1 meets the design requirements.

[0040] After the required embedded bolts are adjusted, fix the embedded bolts, pour concrete, and remove the embedded bolt positioning device for reuse.

[0041] The present invention can quickly locate the installation position of the embedded bolts, and the positioning plate 1 can prevent the embedded bolts from tipping over during the positioning and fixing process; the embedded bolt positioning device can be removed after the embedded bolts are fixed, and can also be removed after the concrete is poured, and is easy to install and disassemble; the adjustable frame structure can be fixed to templates with different spacings, and can also be adapted to the needs of different embedded bolt installation positions; the embedded bolt positioning device has a simple structure, is light in weight, and is easy to transport, which can improve positioning efficiency and accuracy, ensure the installation quality of the embedded bolts, avoid secondary construction due to inaccurate positioning of the embedded bolts during subsequent steel structure installation, and reduce later repair costs.

[0042] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention.
