Description

Technical Field

[0001] This utility model relates to the technical field of pre-embedded positioning, specifically a pre-embedded positioning device for rectangular column anchor bolts. Background Technology

[0002] In the field of building construction, the precise pre-embedding of anchor bolts is a crucial step in ensuring the quality of the installation of the superstructure steel. There are many commonly used methods for pre-embedding anchor bolts for rectangular columns, but in engineering practice, two traditional fixing methods are mainly employed: one is to use binding wire to tie the anchor bolts to the main reinforcing bars, and the other is to weld short reinforcing bars to the main reinforcing bars as positioning supports. When construction workers use a composite fixing process combining binding and welding, the binding process is easily disturbed by external forces, causing displacement deviations in the bolt group, which alters the structural stress system and poses safety hazards.

[0003] Therefore, there is an urgent need for a more reliable and precise anchor bolt pre-embedded positioning device to overcome the shortcomings of existing technologies, improve construction efficiency and quality, and meet the high standards of modern building construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rectangular column anchor bolt pre-embedding positioning device. By adjusting the relative positions of the movable installation component and the fixed installation component, the sliding channel position can be moved, which can accommodate the pre-embedding of rectangular column anchor bolts of different sizes. At the same time, by adjusting the fastening shims in the sliding channel position and fixing them with fastening bolts, the positioning of different quantities and types of bolts can be achieved, thus improving the positioning accuracy.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution:

The positioning device also includes an adjusting spindle, which passes through the movable installation component and is threadedly connected to the fixed installation component. An adjusting nut is threadedly connected to the end of the adjusting spindle away from the fixed installation component.

[0007] In a preferred embodiment, the present invention can be further configured such that: the inner sidewall of the movable mounting component is provided with a first sliding groove and the end of the first sliding groove is provided with a first stop block; the end of the fixed mounting component is provided with a second stop block; the second stop block is slidably connected to the first sliding groove; when the movable mounting component and the fixed mounting component are stretched to a certain length, the first stop block contacts the second stop block.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, this technical solution discloses a rectangular column anchor bolt pre-embedding positioning device, comprising a fixed installation component 1 and a movable installation component 2, both of which are hollow. The movable installation component 2 has a U-shaped design. Two movable installation components 2 and two fixed installation components 1 form a rectangle. This rectangle represents a structural form that can be applied to circles, polygons, etc., and can be designed according to site requirements. The movable installation component 2 is inserted into the end of the fixed installation component 1, and the two can slide relative to each other. An adjusting spindle 3 is also provided, which passes through the movable installation component 2 and is threadedly connected to the fixed installation component 1. An adjusting nut 4 is threadedly connected to the end of the adjusting spindle 3 away from the fixed installation component 1. Here, the adjusting spindle 3 passes through the side wall of the movable installation component 2. By rotating the adjusting spindle 3, the relative position of the movable installation component 2 and the fixed installation component 1 can be changed, thereby enabling the rectangular column anchor bolts to be pre-embedded in different positions, meeting the requirements of more pre-embedded parts, and effectively improving the applicability of the device.

[0021] The adjusting spindle 3 here is a threaded rod. The relative position of the movable mounting component 2 and the fixed mounting component 1 is moved by rotating the threaded rod, and the adjusting nut 4 further locks the threaded rod.

[0022] Furthermore, the inner wall of the movable mounting component 2 is provided with a first sliding groove, and the end of the first sliding groove is provided with a first stop 5. The end of the fixed mounting component 1 is provided with a second stop 6. The second stop 6 is slidably connected to the first sliding groove. When the movable mounting component 2 and the fixed mounting component 1 are stretched to a certain length, the first stop 5 and the second stop 6 come into contact. The first sliding groove provides guidance when changing the rectangular size, making the overall device more coherent and stronger. The first stop 5 and the second stop 6 are provided to prevent the movable mounting component 2 and the fixed mounting component 1 from separating during adjustment.

[0023] Furthermore, both the fixed mounting component 1 and the movable mounting component 2 are provided with sliding channels 7 and fastening bolts 8. The fastening bolts 8 are inserted into the sliding channels 7 and are fixed by fastening nuts 10 and fastening washers 9. By adjusting the position of the fastening washers 9 in the sliding channels 7 and fixing them with the fastening bolts 8, the positioning of different numbers and types of fastening bolts 8 can be achieved, improving the accuracy of positioning.

[0024] Furthermore, the bottom of the movable mounting component 2 is provided with a threaded hole, and a leveling leg 12 is also provided. The leveling leg 12 is connected to the threaded hole through a connector 11. The connector 11 is annular, and both its inner and outer sides are threaded. By adjusting the length of the leveling leg 12, the installation height of the device can be leveled. After leveling, the device is fixed to the mounting surface, the leveling leg 12 is removed, and it can be recycled, saving resource costs.

[0025] The implementation principle of this embodiment is as follows: the fixed installation component 1 is sleeved inside the movable installation component 2, the second stop 6 inside the fixed installation component 1 is slidably engaged in the first sliding groove to prevent the two from sliding off, the fastening bolt 8 passes through the sliding channel 7, and is fixed in position by the fastening washer 9 and the fastening nut 10. By adjusting the relative position of the two movable installation components 2, and then adjusting the position of the fastening washer 9, the positioning of different numbers of fastening bolts 8 for rectangular columns of different sizes can be achieved.

[0026] Adjust the height of the leveling support leg 12, connect the leveling support leg 12 to the positioning device through the connector 11, and after the device installation height is leveled, fix the positioning device on the installation surface, and then remove the leveling support leg and connector 11.
