Description

Technical Field

[0001] This utility model relates to the technical field of anchor bolt mounting brackets, and in particular to a detachable rectangular anchor bolt quick-embedding mounting bracket structure. Background Technology

[0002] In the construction of industrial plants, foundations for large equipment, and steel structure column bases, the pre-embedding of anchor bolts is a crucial step. The accuracy of the anchor bolt's pre-embedding position, especially the spacing between multiple bolts, the row spacing, the verticality of the bolts themselves, and the horizontality of their top elevation, directly affects the installation accuracy, stability, and operational safety of the upper equipment or structure.

[0003] Currently, the common methods for positioning anchor bolts in a rectangular arrangement mainly include: On-site layout and positioning method: Longitudinal and transverse axes are marked on the foundation pad, the position of each bolt is measured and marked one by one, and then fixed individually. This method is cumbersome, inefficient, and easily affected by human measurement errors and environmental factors (such as wind and disturbance), making it difficult to guarantee the uniformity of the spacing between multiple bolts and the overall levelness.

[0004] Temporary positioning template method: Based on the design drawings, a frame template with positioning holes is fabricated on-site or in a processing plant using materials such as angle steel, channel steel, and wooden boards. After the anchor bolts are inserted into the holes and fixed, the entire template is hoisted onto the foundation reinforcement mesh for pouring. Although this method can ensure the relative position of the bolts, it has significant drawbacks: First, the bolt spacing, number, and layout of each group of anchor bolts may differ, requiring repeated design and fabrication of dedicated templates, resulting in high costs, long cycles, and poor flexibility; second, the template itself needs to ensure sufficient rigidity and levelness, requiring high fabrication standards; third, the installation, adjustment, and dismantling of the template are complex, especially inconvenient in large foundations or complex reinforcement meshes; fourth, the template may deform or shift during concrete pouring, affecting the final accuracy. Utility Model Content

[0005] To address the aforementioned issues, the purpose of this utility model is to provide a detachable rectangular anchor bolt quick-embedding installation bracket structure, solving the problem of the lack of a universal positioning tool that can quickly adapt to different specifications and sizes, intuitively set precise spacing, and conveniently ensure installation levelness.

[0006] The technical solution of this utility model is as follows: it includes four square steel bars arranged in parallel pairs, and a cross-shaped guide groove is opened on the inner side of the square steel bars, and scale lines are set on the surface of the square steel bars along the guide groove. One set of square steel has positioning holes at both ends, and the other set of square steel has adjusting holes at both ends. Several bolt clips are slidably installed in the guide groove, and fastening bolts that pass through the guide groove are provided on the surface of the bolt clips. A level is installed at the center of the guide groove on the square steel.

[0007] Furthermore, the positioning hole plate is a single-layer plate, and the adjusting hole plate is a double-layer plate. There is a gap between the two plates of the adjusting hole plate. The gap width is adapted to the thickness of the positioning hole plate, and the combined thickness of the positioning hole plate and the adjusting hole plate is adapted to the thickness of the square steel, so that the adjusting hole plate can clamp the positioning hole plate and avoid the square steel from having a horizontal height difference.

[0008] Furthermore, the positioning hole plate and the adjusting hole plate are provided with perforations evenly spaced on their surfaces, and the perforations on the surfaces of the adjusting hole plate and the positioning hole plate are mutually compatible.

[0009] Furthermore, the square steels in each group are arranged in parallel, and the adjustment holes at both ends of the two groups of square steels clamp the positioning holes, ensuring that the perforations on the surfaces of the positioning holes and adjustment holes are aligned. Bolts are used to pass through the perforations to fix the rectangular positioning frame. The coverage area of ​​the overall frame can be changed by adjusting the relative position of the positioning holes and adjustment holes. At the same time, the frame is not easily deformed after it is formed.

[0010] Furthermore, the bolt clip is divided into a sliding part located in the guide groove and a clip extending through the guide groove into the inner side of the rectangular positioning frame. The clip is a U-shaped structure with a side opening, and the opening end of the clip is flared. The inner wall of the clip is provided with a limiting protrusion. The surface of the sliding part is provided with a pointer pointing to the scale line, which can insert the anchor bolt into the bolt clip laterally. After the anchor bolt is pre-tightened, the bolt clip can move laterally along the guide groove to move away from the fixed anchor bolt. At the same time, the bolt clip can be accurately positioned by aligning the pointer with the scale line.

[0011] Furthermore, there are four levels, each set in a guide groove of one of the four square steel bars, and the levels are bubble level levels.

[0012] Furthermore, the scale lines are precisely spaced, with the smallest scale division being two millimeters.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model can form rectangular frames of different specifications by adjusting the connection position between the positioning hole plate and the adjustment hole plate on the top of two sets of square steel beams, thereby adapting to the layout of rectangular anchor bolts of various specifications. At the same time, the scale lines on the square steel make the spacing of the tongue nails intuitive and precise. Construction personnel only need to move the bolt clips to the specified scale and lock them according to the construction requirements to set the placement position of the anchor bolts, avoiding the errors and time-consuming process caused by repeated measurement and marking.

[0014] 2. This utility model provides good rigidity and stability by using square steel as the main structure, which can resist slight disturbances generated in the construction environment. At the same time, square steel is a general-purpose component with low production cost. The structure of the whole device is simple and has sufficient strength to support repeated use. Furthermore, it is not easily affected by external factors during handling, installation and disassembly, thus ensuring its accuracy. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1-4 As shown, a detachable rectangular anchor bolt quick-embedding installation bracket structure includes four square steel bars 1 arranged in pairs parallel to each other. A cross-shaped guide groove 101 is opened on the inner side of each square steel bar 1 and a scale line 102 is provided on the surface of the square steel bar 1 along the guide groove 101. The scale line 102 is a precise scale with equal spacing, and the smallest scale value of the scale line 102 is two millimeters. One set of square steel 1 has positioning holes 103 at both ends, and the other set of square steel 1 has adjusting holes 104 at both ends. The positioning holes 103 are single-layer plates, and the adjusting holes 104 are double-layer plates. A gap is left between the two plates of the adjusting holes 104, the gap width of which matches the thickness of the positioning holes 103. The combined thickness of the positioning holes 103 and the adjusting holes 104 matches the thickness of the square steel 1, so that the adjusting holes 104 can clamp the positioning holes 103 and avoid horizontal height differences in the square steel 1. The positioning holes 103... The adjustment hole plate 104 and the positioning hole plate 103 are provided with evenly spaced perforations. The perforations on the surfaces of the adjustment hole plate 104 and the positioning hole plate 103 are matched with each other. The square steel 1 in each group is arranged in parallel. The adjustment hole plates 104 at both ends of the two groups of square steel 1 clamp the positioning hole plate 103 and overlap, and ensure that the perforations on the surfaces of the positioning hole plate 103 and the adjustment hole plate 104 are aligned. Bolts are used to pass through the perforations to fix them to form a rectangular positioning frame. The coverage area of ​​the overall frame can be changed by adjusting the relative position of the positioning hole plate 103 and the adjustment hole plate 104. At the same time, the frame is not easy to deform after it is formed. Several bolt clips 2 are slidably arranged in the guide groove 101. The surface of the bolt clip 2 is provided with fastening bolts that pass through the guide groove 101. The bolt clip 2 is divided into a sliding part located in the guide groove 101 and a clip extending into the rectangular positioning frame through the guide groove 101. The clip is a U-shaped structure with a side opening. The opening end of the clip is flared. The inner wall of the clip is provided with a limiting protrusion. The surface of the sliding part is provided with a pointer pointing to the scale line 102. The anchor bolt can be sideways inserted into the bolt clip 2. After the anchor bolt is pre-tightened, the bolt clip 2 can move laterally along the guide groove 101 to move away from the fixed anchor bolt. At the same time, the bolt clip 2 can be accurately positioned by aligning the pointer with the scale line 102. A level 3 is provided at the center of the guide groove 101 of the square steel 1. There are four levels 3, which are respectively set in the guide groove 101 of the four square steel 1. The levels 3 are bubble level levels.

[0019] The working principle of this utility model is as follows: During use, the construction personnel pre-connect four square steel bars 1 with bolts through positioning hole plates 103 and adjusting hole plates 104 to form a rectangular frame. The construction personnel can adjust the size of the rectangular frame by aligning the perforations on the surfaces of positioning hole plates 103 and adjusting hole plates 104, thus adapting to different specifications. Subsequently, the construction personnel use a level 3 to adjust the frame horizontally until the entire frame is level. Then, the bolt clips 2 are moved along the guide grooves 101 on the surface of the square steel bars 1. During the movement, the construction personnel can use the scale lines 102 on the surface of the square steel bars 1 as a base to ensure the position of the bolt clips 2 is correct. As needed, after the bolt clip 2 moves to the required position, the fastening bolt is used to fix its position. Then, the anchor bolt is placed in the clip of the bolt clip 2. At this time, the anchor bolt is restricted by the bolt clip 2, and the bolt clip 2 is restricted by the fastening bolt. Under this restricted state, the anchor bolt will not move. The operator can repeat the above operation to place several anchor bolts in sequence. After all the anchor bolts are placed, they can be pre-fixed or directly fixed. After fixing, the bolt connection between the positioning hole plate 103 and the adjusting hole plate 104 is released, so that the four square steels 1 can be separated and removed for the next use.
