The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0030] The present disclosure provides a convenient bolt fixing tool. Figure 1 and Figure 2 , including: a first template 1 and multiple second templates 2, the multiple second templates 2 are arranged at the top of the first template 1 at intervals along the length direction of the first template 1, the second template 2 is detachably connected to the first template 1 through pins, and two coaxial positioning holes 3 for embedded bolts 6 to pass through are opened on the second template 2, and the diameter of the positioning hole 3 is larger than the diameter of the embedded bolt 6.

[0031] In the disclosed embodiment, the portable bolt fixing tool is composed of a first template 1 and a plurality of second templates 2, and the second templates 2 are connected and fixed to the first template 1 by pins; when the construction process of pre-embedded bolts is carried out, after the first template 1 and the second template 2 are connected by pins, the screw rod of the pre-embedded bolt 6 is passed through the two positioning holes 3 in sequence upward, and the pre-embedded bolt 6 is assembled with the first template 1 and the second template 2, and the pre-embedded bolt 6 is positioned through the two positioning holes 3 to determine the pre-embedded position of the pre-embedded bolt 6, and the assembled first template 1 and the second template 2 are installed on the stair treads so that the pre-embedded bolt 6 is installed in the stair treads, and then concrete is poured; at this time, the concrete will squeeze the pre-embedded bolt 6, and the pre-embedded bolt 6 is limited by the two coaxial positioning holes 3 to avoid serious deviation of the pre-embedded bolt 6, improve the pre-embedded accuracy of the pre-embedded bolt 6, reduce the complexity of the bolt pre-embedded work, reduce the work intensity of the construction personnel, and improve the construction efficiency.

[0032] It should be noted that multiple second templates 2 can be installed in the length direction of the first template 1, and the embedded bolts 6 are installed in the second template 2. In this way, multiple embedded bolts 6 can be embedded at the same time through one first template 1, so as to achieve batch embedding, thereby improving the efficiency of stair construction. The diameter of the positioning hole 3 is slightly larger than the diameter of the embedded bolt 6, which is convenient for fine-tuning the position and angle of the embedded bolt 6 during the bolt embedding construction process, and is also convenient for separating the embedded bolt 6 from the second template 2 after the concrete solidifies.

[0033] In one example, see Figure 2 The number of the second templates 2 is two, and the second templates 2 are distributed at both ends of the first template 1, so that two embedded bolts 6 can be embedded at one time and the positions of the two embedded bolts 6 can be determined.

[0034] In one embodiment of the present disclosure, see Figure 1 and Figure 4 The cross section of the first template 1 is U-shaped, and the second template 2 includes a horizontal plate 201 and an L-shaped plate 202, and the L-shaped plate 202 is arranged at the top of the horizontal plate 201; the cross section of the second template 2 is H-shaped. In this way, the U-shaped first template 1 and the H-shaped second template 2 are assembled with each other, and at the same time cooperate with the stair steps to accurately position and embed the embedded bolts 6 in the stairs, thereby improving the embedding accuracy of the embedded bolts 6.

[0035] It should be noted that when the first template 1 and the second template 2 are matched with the stair treads, the opening of the first template 1 faces the side away from the stair treads, the side wall of the first template 1 away from the opening is in close contact with the side wall of the stair treads, the bottom surface of the second template 2 is in close contact with the top wall of the stair treads, the upper side wall of the first template 1 and the bottom wall of the second template 2 are connected by pins, and the first template 1 and the second template 2 limit the size of the stair treads, that is, the sizes of the first template 1 and the second template 2 are adapted to the sizes of the stair treads.

[0036] In one embodiment of the present disclosure, see Figures 1 to 3 , a plurality of first connection holes 4 are arranged at intervals on both side walls of the first template 1, and the first connection holes 4 on the two side walls are arranged coaxially; a plurality of second connection holes 5 are arranged at intervals on one end of the horizontal plate 201, and the second connection holes 5 are connected to the first connection holes 4 by pins. In this way, the first template 1 and the second template 2 are connected by a plurality of pins, and the first template 1 and the second template 2 are convenient to disassemble and assemble and firmly connected; the connection between the first template 1 and the second template 2 is achieved by the plurality of first connection holes 4 and second connection holes 5 arranged at intervals, and at the same time, the position of the second template 2 on the first template 1 can be conveniently adjusted according to the change of the embedded position of the embedded bolts 6 on the stair treads, thereby improving the construction efficiency.

[0037] In one example, see Figure 3 Two second connection holes 5 are provided on the horizontal plate 201, and the two second connection holes 5 are connected to the two first connection holes 4 on the first template 1 through pins, so that the first template 1 and the second template 2 are firmly connected.

[0038] Alternatively, see Figure 1 , the horizontal plate 201 is flush with the side wall of the first template 1. In this way, it is convenient to position the first template 1 and the second template 2 during assembly, and it is convenient to connect the first template 1 and the second template 2, thereby improving the positioning accuracy of the embedded bolts 6.

[0039] Optionally, the horizontal plate 201 and the L-shaped plate 202 are connected by welding, and the horizontal plate 201 and the L-shaped plate 202 are firmly connected and will not separate during use, thereby improving the service life of the second template 2.

[0040] In one embodiment of the present disclosure, see Figure 1 The horizontal planes of the horizontal plate 201 and the L-shaped plate 202 are respectively provided with positioning holes 3, and the two positioning holes 3 are coaxially arranged. In this way, the position of the embedded bolt 6 is limited by the two positioning holes 3 located on the same axis, so as to avoid the position of the embedded bolt 6 from being offset during the concrete pouring process, and improve the embedding accuracy of the embedded bolt 6.

[0041] Alternatively, see Figures 1 to 3The positioning hole 3 on the horizontal plane of the L-shaped plate 202 is located at the center of the horizontal plane of the L-shaped plate 202, so as to facilitate the determination of the position of the embedded bolt 6 on the horizontal plane of the stair step.

[0042] In one embodiment of the present disclosure, the diameters of the first connection hole 4 and the second connection hole 5 are both 10 mm; the diameters of the positioning holes 3 are both 15 mm. In this way, the first connection hole 4 and the second connection hole 5 are adapted to the pins, which facilitates the connection between the first template 1 and the second template 2; the positioning hole 3 is adapted to the embedded bolt 6, which facilitates the positioning and embedding of the embedded bolt 6.

[0043] In one embodiment of the present disclosure, the length of the horizontal plate 201 is 260 mm, the width of the horizontal plate 201 is 150 mm; the length of the horizontal plane of the L-shaped plate 202 is 198 mm, and the height of the vertical plane of the L-shaped plate 202 is 103 mm. In this way, the second template 2 is adapted to the stair treads, making it easy to install the second template 2 on the stair treads, thereby determining the position of the embedded bolts 6.

[0044] In one example, the spacing between the second connection hole 5 and the long side of the horizontal plate 201 is 25 mm, the spacing between the second connection hole 5 and the short side of the horizontal plate 201 is 20 mm, the spacing between two adjacent second connection holes 5 is 100 mm, and the spacing between two adjacent first connection holes 4 is 50 mm.

[0045] Optionally, the distance between the positioning hole 3 and the long side of the horizontal plate 201 is 75 mm, and the distance between the positioning hole 3 and the short side of the horizontal plate 201 is 97.5 mm.

[0046] In one embodiment of the present disclosure, the first template 1 and the second template 2 are both made of an aluminum alloy plate with a thickness of 3 mm. In this way, the first template 1 and the second template 2 are easy to process, have a light structure and high strength, are easy to carry and transport, and are easy to install and disassemble the first template 1 and the second template 2, thereby improving the convenience of use and service life of the fixing tool and reducing the construction cost.
