[0025] Example 1

[0026] An auxiliary tool for frame column construction, such as Figure 1As shown, it includes a solid connecting rod 1, with cross bars 2 welded to both sides of one end of the connecting rod 1, and the middle of the cross bar 2 is welded to the connecting rod 1, and a gap is left between the two cross bars 2 to accommodate the steel bars to be bent, that is, the vertical distance between the two cross bars 2 is greater than the diameter of the steel bars to be bent. A handrail is provided at one end of the connecting rod 1 away from the cross bar 2.

[0027] The handrail bar includes a first tube body 3 and a second tube body 4. The first tube body 3 is sleeved on the connecting rod 1 and welded to the connecting rod 1, and the second tube body 4 is slidably connected to the outside of the first tube body 3. A positioning bead 301 is fixed on the first tube body 3, and a plurality of positioning holes 401 are provided on the side wall of the second tube body 4 in the vertical direction. The positioning bead 301 is ejected into one of the positioning holes 401. When the length of the handrail bar needs to be adjusted, the positioning bead 301 is pushed inward to separate the positioning bead 301 from the positioning hole 401, and the second tube body 4 is slid to eject the positioning bead 301 into the positioning hole 401 at the appropriate position.

[0028] In this embodiment, two positioning beads 301 are symmetrically arranged on both sides of the outer wall of the first tube body 3, and four positioning holes 401 are arranged in the vertical direction on each side; more positioning beads can also be arranged according to the use requirements.

[0029] In this embodiment, a tightening bolt 5 is also provided to increase the stability of the connection between the first tube body 3 and the second tube body 4. The first tube body 3 is provided with a plurality of first threaded holes 302 in the vertical direction, and the second tube body 4 is provided with a second threaded hole at the end close to the first tube body 3. After adjusting the length of the handrail, the tightening bolt 5 is inserted into the second threaded hole through the first threaded hole 302 and tightened. In this embodiment, the distance between two adjacent first threaded holes 302 is the same as the spacing distance between two adjacent positioning holes 401; two or more tightening bolts 5 can be provided, evenly distributed along the circumference of the handrail.

[0030] The two crossbars 2 are fixed with anti-skid pads 201 on the side walls that contact the steel bars to be bent, which are used to increase the friction with the steel bars to prevent the steel bars from sliding during bending. The outer wall of the second tube body 4 is fixed with an anti-skid sleeve 402 to increase the friction between the hand and the second tube body 4, making it easier to grasp.

[0031] The method of using the auxiliary tool for frame column construction provided in this embodiment is as follows: when using, first adjust the length of the handrail rod according to the length of the reserved steel bar or the actual construction needs, push the positioning bead 301 inward to disengage the positioning bead 301 from the positioning hole 401, slide the second tube body 4 to insert the positioning bead 301 into the appropriate positioning hole 401, and tighten the tightening bolt 5 with the first threaded hole 302 and the second threaded hole to fix; then place the reserved steel bar on the frame column in the interval between the two cross bars 2 on the same side of the connecting rod 1, such as Figure 2As shown, finally, the second tube body 4 is held and pressed downward with force to bend the reserved steel bar.

[0032] The middle position of the cross bar 2 provided in this embodiment is welded to the connecting rod 1. When in use, two adjacent reserved steel bars are respectively inserted into the two intervals on both sides of the connecting rod 1, and the two adjacent reserved steel bars can be bent at the same time, which greatly shortens the operation time. The cross bar and the connecting rod in this embodiment can be made of steel bars.

[0033] Example 2

[0034] An auxiliary tool for frame column construction, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: in this embodiment, the first tube body 3 and the second tube body 4 are slidably connected by a sliding groove and a slider, and a spring 7 is also provided between the first tube body 3 and the second tube body 4. Figure 3 shown.

[0035] Two slide grooves 403 are symmetrically arranged in the middle of the inner wall of the second tube body 4, and two sliders 303 are symmetrically fixed on the outer wall of the first tube body 3, and each slider 303 is slidably connected in a slide groove 403. The provided sliders 303 and the slide grooves 403 can make the second tube body 4 move smoothly, ensuring that the two positioning beads 301 are inserted into the corresponding positioning holes 401 at the same height at the same time to avoid misalignment.

[0036] The end of the first tube body 3 extending into the second tube body 4 is a closed end, and the end of the second tube body 4 away from the positioning hole 401 is also a closed end. A spring 7 is arranged between the closed ends of the first tube body 3 and the second tube body 4, and the two ends of the spring 7 are fixedly connected to the first tube body 3 and the second tube body 4 respectively.

[0037] In this embodiment, each side of the second tube body 4 is provided with four positioning holes 401, which are the first positioning hole, the second positioning hole, the third positioning hole, and the fourth positioning hole from top to bottom. The initial state of the auxiliary tool is that the positioning bead 301 is inserted into the first positioning hole located at the top, that is, the length of the handrail is the longest, and the spring 7 set at this time is in a stretched state; when the length of the handrail needs to be shortened, one hand keeps the connecting rod 1 in a vertical state, and the other hand uses two fingers to push the positioning bead 301 inward to disengage the positioning bead 301 from the positioning hole 401, and the spring 7 is reset. The second tube body 4 moves upward under the action of the elastic force of the spring 7, and the positioning bead 301 is automatically inserted into the adjacent second positioning hole. When the positioning bead 301 needs to be inserted into the third positioning hole and the fourth positioning hole, the above operation can be repeated. The set spring makes it more convenient to use when shortening the length of the handrail.

[0038] Example 3

[0039] An auxiliary tool for frame column construction, such as Figure 4As shown, the technical solution in this embodiment is basically the same as that in Implementation 2, except that: a hammer head is detachably connected to the end of the second tube body 4 away from the first tube body 3, and a threaded connection is adopted in this embodiment.

[0040] A nail pulling groove 8 is provided at one end of the hammer head, and a striking surface 9 is provided at the other end. A threaded hole is provided in the middle of the hammer head, and a threaded groove matching the threaded hole of the hammer head is provided on the outer wall of one end of the second tube body 4 away from the first tube body 3. When removing the frame column formwork, a nail puller is needed to remove the nails on the formwork, and sometimes a hammer is needed to tap the formwork to separate it from the concrete. The staff needs to carry a variety of tools, which is inconvenient to work. The auxiliary tool provided in this embodiment is provided with a nail pulling groove and a striking surface at the same time, can perform a variety of operations, is easy to carry, and is easy to use. When using, it is only necessary to thread the hammer head with the second tube body 4.

[0041] The auxiliary tool for frame column construction provided by the utility model can quickly bend the reserved steel bars of the frame column. The bending using the lever principle saves time and effort. The length of the handrail rod can be adjusted according to actual needs such as the length of the reserved steel bars or the bending length to find the most suitable force application point. It can also perform operations such as removing iron nails from the formwork and knocking on the formwork. It has multiple functions, is easy to carry, has a simple structure, is easy to use, and can significantly improve construction efficiency.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
