Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for concrete construction, and in particular to an anchor bolt positioning mold for concrete pouring. Background Technology

[0002] During concrete pouring, anchor bolts are often pre-embedded in the concrete structure for subsequent equipment installation, component connection, and other operations. The installation accuracy of the anchor bolts directly affects the quality of subsequent construction and structural stability. If the anchor bolts are not positioned accurately, have excessive vertical deviation, or are unevenly spaced, it can lead to difficulties in equipment installation, uneven stress, and even affect the load-bearing capacity of the entire concrete structure.

[0003] Current anchor bolt positioning methods mostly involve manually marking the bolts and then directly inserting them into the formwork. This method is cumbersome, has low positioning accuracy, is easily affected by the skill level of the construction workers, and the anchor bolts are prone to displacement and tilting during concrete pouring. Some positioning molds have fixed structures, making them unsuitable for different sized construction areas and installation heights, resulting in poor versatility and significant limitations in use. Therefore, there is an urgent need for a concrete anchor bolt positioning mold that offers precise positioning, flexible adjustment, and strong versatility. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an anchor bolt positioning mold for concrete pouring, so as to solve the technical problems of low positioning accuracy and poor mold versatility of existing anchor bolts.

[0005] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A positioning mold for anchor bolts used in concrete pouring includes a positioning plate with a circular through hole in the middle and at least four positioning holes corresponding to the anchor bolts to be positioned. The anchor bolts to be positioned are installed in the positioning holes, and fastening nuts and positioning nuts are threadedly connected to the anchor bolts at the upper and lower ends of the positioning holes, respectively.

[0006] As a further improvement of this utility model, it also includes a positioning frame, wherein the positioning plate is placed on top of the positioning frame.

[0007] As a further improvement of this utility model, the positioning frame includes a rectangular support frame, and support legs are installed at the four bottom corners of the rectangular support frame.

[0008] As a further improvement of this utility model, the support leg is a height-adjustable telescopic structure, including a first support rod and a second support rod. The lower end of the first support rod is slidably installed inside the second support rod. An adjustment elongated hole is formed on the second support rod along its height direction. A mounting circular hole is formed at the end of the first support rod located inside the second support rod. An adjustment screw is installed in the mounting circular hole, and both ends of the adjustment screw pass through the adjustment elongated hole and are threadedly connected to adjustment nuts. By adjusting the position of the adjustment screw in the adjustment elongated hole, the height of the support leg can be flexibly adjusted to adapt to construction needs of different heights. After adjustment, it is fixed by tightening the adjustment nuts, making the operation simple.

[0009] As a further improvement of this utility model, scale lines are provided on both the first support rod and the second support rod along their height direction, which makes it easy for construction personnel to intuitively read the height of the support legs, ensure that the height of the four support legs is consistent, improve the levelness of the positioning plate, and thus ensure the verticality of the anchor bolt installation.

[0010] As a further improvement of this utility model, the rectangular support frame includes two parallel first support plates, the positioning plate is placed on the two first support plates, and two second support plates are connected between the two ends of the two first support plates.

[0011] As a further improvement of this utility model, the first support plate has symmetrical rectangular mounting holes at both ends, and the two ends of the second support plate are installed in the corresponding rectangular mounting holes. A first locking nut is threaded onto the bottom of the first support plate at the position corresponding to the rectangular mounting hole, and the front end of the first locking nut abuts against the second support plate at the corresponding position. By adjusting the position of the second support plate in the rectangular mounting hole, the width of the rectangular support frame can be adjusted to adapt to positioning plates and construction areas of different sizes. After adjustment, tightening the first locking nut achieves a firm connection between the first support plate and the second support plate.

[0012] As a further improvement of this utility model, a U-shaped bracket is fixed to the top of the first support rod, and both ends of the first support plate are installed in the U-shaped slots of the corresponding U-shaped brackets. A second locking nut is threaded onto the side wall of the U-shaped bracket, and the front end of the second locking nut abuts against the first support plate at the corresponding position. The U-shaped bracket facilitates the quick installation and removal of the first support plate, and the second locking nut can firmly fix the first support plate to the U-shaped bracket, preventing displacement during construction and ensuring the stability of the positioning frame.

[0013] The beneficial effects of this utility model are: 1. Significantly improved positioning accuracy: The positioning plate achieves standardized control of anchor bolt spacing through pre-set positioning holes. The fastening nuts at the upper and lower ends of the positioning holes form a double locking structure with the positioning nuts, effectively limiting the radial sway and axial displacement of the anchor bolts. The verticality error of the anchor bolts is controlled to a very small range, with a spacing error of ≤±2mm. This completely solves the deviation problem caused by traditional manual positioning, ensuring accurate adaptation of subsequent equipment installation and component connection, and improving the load-bearing reliability of concrete structures.

[0014] 2. Highly adaptable to various scenarios: The support legs adopt a telescopic adjustment structure to meet the anchor bolt pre-embedding requirements of concrete pouring of different thicknesses; The rectangular support frame can flexibly adjust its length and width through the splicing design of the first support plate and the second support plate, adapting to the positioning requirements of anchor bolt groups of different specifications and pouring surfaces of different areas, without the need to customize special molds for specific scenarios, thus reducing construction costs.

[0015] 3. Significantly improved construction efficiency: The positioning frame adopts a modular splicing structure, and the U-shaped card seat and rectangular mounting hole design enable rapid assembly and disassembly. No welding or complex tools are required throughout the process. Compared with the traditional manual marking and reinforcement process, the construction cycle is shortened by more than 40%, and the mold can be reused ≥50 times, further improving the economic efficiency of construction.

[0016] 4. Combining structural stability and protection: The multiple fixing structure of the first locking nut, the second locking nut, and the adjusting nut ensures that the mold does not shift or deform in the vibration environment of concrete pouring; the four-point support design of the rectangular support frame and the circular through hole in the middle of the positioning plate not only ensure the overall force of the mold is balanced, but also facilitate the flow and filling of concrete, avoid blind spots in pouring, and improve the density of concrete.
