Description

Technical Field

[0001] This utility model belongs to the technical field of tower cranes and relates to the pre-embedded positioning of anchor bolts, specifically a positioning mold for pre-embedded anchor bolts in the grid-shaped base of a tower crane. Background Technology

[0002] Tower cranes are a widely used type of construction lifting machinery in modern construction, mainly used for the vertical and horizontal transport of materials and the installation of building components in building construction. When the tower crane base is a grid-shaped base, anchor bolts are usually pre-embedded for fixation. These bolts need to be positioned using the base, requiring the grid-shaped base to be transported to the construction site in advance. A crane or other auxiliary lifting equipment is then used to place the base in the center of the foundation's reinforcing mesh. After the base is leveled, the anchor bolts are inserted in the corresponding positions and fixed before concrete pouring. This method has the following drawbacks: 1. It is difficult to control the spatial positioning accuracy of anchor bolts, and the verticality deviation rate of anchor bolts is as high as ±3°; the bolts may tilt during concrete pouring, which may cause safety hazards to the subsequent installation and use of tower cranes.

[0003] 2. Auxiliary lifting equipment is required for hoisting and positioning, with an average time of 4-6 hours per unit.

[0004] 3. The turnover and transportation costs of the grid-shaped base are high, accounting for 5%-10% of the total foundation construction cost, which is neither economical nor convenient.

[0005] Based on the above problems, this utility model urgently needs to propose a new positioning mold for pre-embedded anchor bolts on the grid-shaped base of tower cranes. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a positioning mold for pre-embedded anchor bolts in the grid-shaped base of tower cranes, which solves the problems of difficulty in controlling spatial positioning accuracy, reliance on auxiliary lifting equipment for hoisting and positioning, and high turnover and transportation costs of grid-shaped bases when pre-embedding anchor bolts.

[0007] This utility model is achieved using the following technical solution: A positioning mold for pre-embedded anchor bolts on the grid-type base of a tower crane includes frame units, and four sets of frame units together form a closed positioning mold. The frame unit includes horizontally fixed and vertically fixed positioning tubes, with a vertically fixed positioning tube below the cross-fixed position; an oblique reinforcing tube is fixed at the inner angle formed by the cross-fixed horizontal and vertical positioning tubes, and a guide post is fixedly connected to the oblique reinforcing tube; a guide mounting tube is fixedly connected to the outer end of the horizontal and vertical positioning tubes, and two sets of guide posts are fixedly connected to the guide mounting tube, with anchor bolts passing through the guide posts; a double-hole connecting plate is fixedly connected to the inner end of the horizontal and vertical positioning tubes. When assembling the four frame units, after the adjacent double-hole connecting plates are mated, bolt assemblies are inserted to complete the connection between the adjacent frame units.

[0008] More preferably, the horizontal positioning tube and the vertical positioning tube are welded perpendicularly to each other.

[0009] More preferably, horizontal reinforcing ribs are provided between the horizontal positioning tube and the vertical positioning tube, between the outer end of the horizontal positioning tube and the guide mounting tube, and between the outer end of the vertical positioning tube and the guide mounting tube.

[0010] More preferably, a vertical reinforcing rib is provided between the horizontal positioning tube and the vertical positioning tube.

[0011] When applying it, first clean the area of ​​the steel mesh on the tower crane foundation to ensure that the center of the mesh is clear and free of debris.

[0012] Then, the assembled positioning mold is placed at the center of the tower crane foundation steel mesh (the center of the positioning mold coincides with the center of the tower crane foundation steel mesh), and the connection of the double-hole connecting plate coincides with the center line of the mesh, completing the horizontal positioning of the frame. Four equal-height blocks are placed to position the mold at a certain height using vertical positioning tubes; after positioning, anchor bolts are inserted through the guide columns, and the upper and lower nuts are tightened during insertion to ensure that the anchor bolts are vertical and not skewed.

[0013] The beneficial effects of this utility model are: 1. This utility model is designed for tower cranes with existing grid-shaped bases. By designing a positioning mold for pre-embedded anchor bolts, it enables convenient positioning of anchor bolts. The operation is simple and effectively shortens the positioning process time (from 6 hours to 1.2 hours), thus reducing the labor cost of the positioning process.

[0014] 2. This utility model does not rely on auxiliary lifting equipment for hoisting and positioning, saving auxiliary hoisting costs and reducing transportation costs; at the same time, it improves the positioning qualification rate of anchor bolts, thereby improving work efficiency and quality.
