Description

Technical Field

[0001] The invention belongs to the technical field of building foundation construction, and more specifically, relates to an auxiliary positioning device for embedded anchor bolts and a use method thereof. Background Art

[0002] Anchor bolts are fasteners used in buildings and engineering structures. Their main function is to connect the main part of the building to the foundation to ensure that the building remains firm under the influence of earthquakes or other external forces. They are generally used in infrastructure such as railways, roads, power companies, factories, mines, bridges, tower cranes, large-span steel structures and large buildings, and have strong stability.

[0003] Since the anchor bolts are used to connect the main part of the building and the foundation to ensure that the building remains firm under the influence of earthquakes or other external forces, the correctness of their position and elevation directly determines whether the entire structure can be used normally and its service life. In the prior art, anchor bolts are generally installed in a pre-buried manner, and at the same time, auxiliary positioning devices are used to position and fix the anchor bolts to ensure that the position of the bolts is accurate. For example, a Chinese patent with document number CN204370465U discloses a pre-buried anchor bolt positioning bracket, including two equal-length vertical bracket units and three equal-length horizontal bracket units. The three horizontal bracket units are respectively fixed at the top, middle and bottom between the two vertical bracket units. The bracket as a whole is a Japanese-shaped frame structure, and each of the two ends of the vertical bracket unit is respectively provided with a mounting circular hole. A Chinese patent with document number CN111485574B discloses a steel column foundation embedded anchor bolt positioning device and a construction method thereof, wherein the positioning device comprises a positioning bracket, which is fixed on a foundation cushion layer, and the positioning bracket comprises four steel bars and a first connecting component, wherein the four steel bars are vertically distributed on the foundation cushion layer in the form of a cube, the bottom ends of the steel bars are fixed to the foundation cushion layer, and two adjacent steel bars are horizontally connected by the first connecting component, so that the four steel bars are connected as a whole; four second connecting components for connecting embedded anchor bolts are provided at the top ends of the steel bars, and the lower ends of the embedded anchor bolts are connected to the second connecting components, thereby realizing the positioning of the embedded anchor bolts.

[0004] Although the auxiliary positioning device of the above patent has a simple structure, is easy to operate, and can effectively improve the installation accuracy of the embedded anchor bolts, it cannot solve some problems existing in the prior art, such as: (1) the auxiliary positioning device has a small adjustable range and poor secondary adjustability; (2) a single auxiliary positioning device can only position and fix a limited number of anchor bolts, and cannot position a large number of anchor bolts at the same time, resulting in reduced construction efficiency.

[0049] Specifically, Figures 1 to 3 As shown, the support module is embedded in the working surface 1 to support the positioning module and multiple anchor bolts 4. The support module includes: embedded parts 5 and support columns 6; the embedded parts 5 are arranged on the working surface 1; the support columns 6 are vertically arranged on the upper end of the embedded parts 5. During use, by arranging the embedded parts 5 in the working surface, the embedded parts 5 and the working surface form an integral structure, ensuring that the embedded parts 5 will not be displaced or loosened during the working process, thereby providing a stable foundation for the entire positioning device; secondly, by vertically arranging the support columns 6 on the upper end of the embedded parts 5, a vertical support structure is formed, and due to the stability of the embedded parts 5, the support columns 6 can stably support the positioning module and the anchor bolts 4, ensuring the stability and reliability of the entire positioning device.

[0050] Preferably, the upper surface of the embedded part 5 is not lower than the upper surface of the working surface 1, so that the position and height of the embedded part 5 can be more accurately controlled during the construction process. Through precise positioning, the embedded part 5 can accurately support the support column 6 installed subsequently, ensuring the verticality and stability of the support column 6, thereby simplifying the construction process through precise positioning, reducing the workload of subsequent adjustments and corrections, and improving construction efficiency and quality.

[0062] Preferably, discontinuous grooves 811 are evenly distributed on both sides of the upper end of the upper main beam 81, and the length of the upper secondary beam 82 is adapted to the distance between the two adjacent discontinuous grooves 811 of the two upper main beams 81, so that the upper secondary beam 82 can be stably clamped between the two upper main beams 81 through the two discontinuous grooves 811, and the upper secondary beam 82 can be conveniently disassembled and assembled on the upper main beam 81 by tools such as a rubber hammer.

[0063] Preferably, the length of the discontinuous groove 811 is greater than the width of the upper beam 82 , so as to conveniently and accurately adjust the position of the upper beam 82 .
