DETAILED DESCRIPTION

[0015] The following will be combined with specific embodiments and attached Figure 1-2 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0016] A bolt embedded fixing frame comprises two primary fixing rods 1 arranged in parallel, the primary fixing rods 1 are tubular structures, and their cross-sectional figures are rectangular. The two primary fixing rods 1 are arranged up and down, and two secondary fixing rods 2 are slidably connected to the two primary fixing rods 1. Both ends of the secondary fixing rods 2 are fixedly connected with a sliding sleeve 22, and the sliding sleeve 22 is a sleeve with a rectangular hole opened inside. The size of the rectangular hole on the sliding sleeve 22 is slightly larger than the primary fixing rod 1, so that the sliding sleeve 22 can be sleeved on the primary fixing rod 1 and slide freely. Each sliding sleeve 22 is provided with a threaded hole, and a sliding fixing bolt 23 is threadedly connected in the threaded hole. The sliding fixing bolt 23 passes through the sliding sleeve 22. When the sliding sleeve 22 is sleeved on the primary fixing rod 1, tightening the sliding fixing bolt 23 can make the end of the sliding fixing bolt 23 press against the primary fixing rod 1, so that the primary fixing rod 1 and the sliding sleeve 22 are pressed and fixed together.

[0017] Four embedded bolt fixing holes 21 are equidistantly provided on the secondary fixing rod 2. The embedded bolt fixing holes 21 can be used to fix the embedded bolts 4. The embedded bolts 4 are inserted into the embedded bolt fixing holes 21, and a nut 41 is threadedly connected to the embedded bolts 4 on both sides of the secondary fixing rod 2. The two nuts 41 are tightened in opposite directions so that the two nuts 41 are tightened together in the direction of the secondary fixing rod 2. Finally, the two nuts 41 are pressed tightly against the two sides of the secondary fixing rod 2, so that the nuts 41 and the secondary fixing rod 2 are fixed to each other, so that the embedded screw threadedly connected to the nuts 41 can be fixedly connected to the secondary fixing rod 2.

[0018] The ends of the primary fixing rods 1 are provided with fixing devices 3, and the fixing devices 3 include a telescopic adjustment rod 31, and the telescopic adjustment rod 31 is an L-shaped structure. The sliding sleeve 22 at one end of the telescopic adjustment rod 31 is placed in the inner hole of the primary fixing rod, and the two can slide relative to each other. The other end of the telescopic adjustment rod 31 is fixedly connected with a reinforcement foot 32, and the reinforcement foot 32 is arranged parallel to the primary fixing rod 1. A threaded hole is provided on the telescopic adjustment rod 31 at a position opposite to the reinforcement foot 32, and a mounting fixing bolt 33 is connected to the thread in the threaded hole. The nut of the mounting fixing bolt 33 is located at On the side away from the reinforcing leg 32, the screw rod of the installation fixing bolt 33 is opposite to the reinforcing leg 32. Tightening the installation fixing bolt 33 can make the screw rod and the reinforcing leg 32 close to each other and clamp them, so that the fixing device 3 can be clamped and fixed on the square wood or square tube 5 used for reinforcement of the template, thereby meeting the requirement of the utility model to be fixed on the pre-cast concrete wall. The reinforcing leg 32 is provided with an anti-slip pad made of rubber material, which can prevent the reinforcing leg 32 and the installation fixing bolt 33 from sliding when clamped on the square tube 5 due to loose clamping, thereby affecting the positioning accuracy of the embedded bolt 4.

[0019] The telescopic adjustment rod 31 is slidably connected to the primary fixing rod 1. By virtue of the characteristics that the two can be telescopic in length, the utility model can be adjusted so that it can be clamped on template walls at different widths, and has a wider applicability. A threaded hole is provided at the end of the primary fixing rod 1, and a telescopic fixing bolt 11 is threadedly connected in the threaded hole. The telescopic fixing bolt 11 passes through the tube wall of the primary fixing rod. When the telescopic adjustment rod 31 and the primary fixing rod 1 are adjusted to a suitable length, the telescopic fixing bolt 11 can be tightened so that the screw end of the telescopic fixing bolt 11 is against the telescopic adjustment rod 31 located inside the primary telescopic rod, so that the primary telescopic rod and the telescopic adjustment rod 31 can be fixedly connected, which is convenient for assembly and turnover.
