Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0025] See Figures 1-7 The present invention provides a method for positioning an adjustable pre-embedded bolt in assembly, comprising:
[0026] An auxiliary positioning device is fabricated, comprising: a connecting pipe 1 for forming the frame; a four-way pipe joint 2 for vertically connecting the connecting pipes 1 to each other; a vacuum chain positioning clamp 3 for locking the pre-embedded bolts; and a pipe clamp 4 for fixing the vacuum chain positioning clamp 3 to the connecting pipe 1.
[0027] Four connecting pipes 1, which are placed horizontally and vertically in a staggered manner, are connected to form a frame through four-way pipe joints 2. According to the number of pre-embedded bolts, select the corresponding number of vacuum chain positioning clamps 3 and pipe clamps 4, and fix the vacuum chain positioning clamps 3 to the connecting pipes 1 through the pipe clamps 4.
[0028] The pre-embedded bolts are fixed in the vacuum chain positioning clamp 3, and the size of the frame and the position of the pipe clamp 4 on the connecting pipe 1 are adjusted according to the design position of the pre-embedded bolts during the fixing process.
[0029] Move the adjusted auxiliary positioning device to the position of the foundation to be poured, and align it according to the design elevation of the pre-embedded bolts;
[0030] The grout is used to pour the foundation to be poured and the pre-embedded bolts are then installed.
[0031] In practice, the connecting pipe 1 is made of galvanized square tubing, which is lightweight and corrosion-resistant. It consists of a first connecting pipe located on the upper side and a second connecting pipe located on the lower side. The first connecting pipe has an axially extending connecting hole 5 that penetrates the top and bottom sides. The second connecting pipe has a connecting groove 6 on its top surface, and toothed slots 7 are provided on two sides of the connecting groove 6 near the bottom.

The pins 9 on both sides of the bottom of the knob-type spring pin 8 engage with the toothed slots 7.
[0032] During the actual pouring, fine aggregate concrete can be used for the first grouting until it reaches 200mm below the design elevation. After the first grouting has initially set, the auxiliary positioning device can be removed, and a second grouting can be performed until the design elevation is reached. The two-stage pouring method provides the stability of the pre-embedded structure.
[0033] During implementation, a scale 10 is provided on the top surface of the connecting pipe 1 along the axial direction to facilitate adjustment of the frame size according to the design position of the pre-embedded bolts.

The upper clamping finger includes two first extension chains 14 with one end hinged to the pipe clamp 4 and arranged in parallel. A locking block 15 is hinged between the other ends of the two first extension chains 14. It also includes two second extension chains 16 with one end hinged to the locking block 15 and arranged in parallel. A locking block 17 is hinged between the other ends of the two second extension chains 16. The connecting rivet 13 is rotatably connected to the locking block 17 in the lower clamping finger and threadedly connected to the locking block 17 in the upper clamping finger.
[0036] The solution provided by this invention firstly improves the construction method, allowing the equipment to be reused repeatedly, reducing project costs, increasing construction efficiency and economic benefits, and shortening the construction period; secondly, it can be assembled and adjusted according to the specific situation of the pre-embedded bolts, such as the number, diameter, quantity and position of the bolts, so that the frame as a whole can move accurately back and forth and left and right, and has reliable fixing measures to ensure the accuracy of the position of the pre-embedded bolts, which can meet the installation requirements of bolts of different specifications, sizes and positions.
