Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, specifically to a magnetic assisted welding device for masonry tie bars. Background Technology

[0002] To ensure the integrity of the main structure and the masonry work, tie bars are installed at the initial design stage to provide flexible connections to the main structure. In many regions, to ensure the quality of the main concrete, the installation of tie bars via rebar anchoring is not permitted, necessitating the use of pre-embedded welding. Traditional rebar anchoring has two drawbacks: a) drilling holes damages the main reinforcement bars in the walls and columns, affecting structural safety; b) the anchoring process easily damages the quality of the main concrete. Ordinary pre-embedded welding also has two drawbacks: 1) it requires two workers to complete the welding; 2) the quality of the weld cannot be guaranteed. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this invention is as follows:

[0005] A magnetic assisted welding device for masonry tie bars includes a rebar support, a rebar limiting groove, a bubble level, and a handheld magnetic suction device. The handheld magnetic suction device is installed inside the rebar support to fix the front end of the rebar support to the surface of the embedded steel plate. Rebar limiting grooves are provided on both sides of the top of the rebar support. A bubble level is also provided at the top of the rebar support.

[0006] Preferably, the steel bar support includes two vertical angle steels arranged longitudinally, and the top ends of the two vertical angle steels are respectively connected to top angle steels arranged in the front-back direction. The two top angle steels are fixed together by welding with a steel plate. The bubble level is fixed on the upper surface of the steel plate, and the upper surfaces of the two top angle steels are provided with steel bar limiting grooves in the front-back direction.

[0007] Preferably, the front end of the top angle steel is welded and fixed to the upper end of the vertical angle steel, or the front end of the top angle steel is hinged to the upper end of the vertical angle steel via a hinge shaft.

[0008] Preferably, the cross-section of the rebar limiting groove is arc-shaped, and the inner diameter of the arc matches the outer diameter of the tie bar to be welded.

[0009] Preferably, the inner surface of the rebar limiting groove is further provided with an elastic body, and the tie bar is tightly connected to the rebar limiting groove through the elastic body.

[0010] Preferably, a guide groove is welded between the two vertical angle steels via a connecting plate, wherein the guide groove is a structure consisting of two opposing arc-shaped plates or annular plates.

[0011] Preferably, the handheld magnetic suction device includes a handle and a cylindrical magnetic suction device fixedly connected to the front end of the handle. A fixing ring is coaxially fixedly connected to the outer wall of the magnetic suction device. The fixing ring is used in conjunction with the top end of the guide groove and is used to press the front end of the steel bar support against the surface of the embedded steel plate when the magnetic suction device adsorbs the embedded steel plate on the surface of the building structure.

[0012] Preferably, the cylindrical magnetic attraction device is a permanent magnet or an electromagnet. When it is an electromagnet, the handle is provided with an electromagnet adjustment button.

[0020] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0022] Example 1

[0023] A magnetic-assisted welding device for masonry tie bars, such as Figure 1 , 2 As shown in Figure 3, the device includes a rebar support 1, a rebar limiting groove 4, a bubble level 3, and a handheld magnetic suction device 5. The rebar support 1 is equipped with a handheld magnetic suction device 5 to fix the front end of the rebar support 1 to the surface of the pre-embedded steel plate 13. The top two sides of the rebar support 1 are respectively provided with rebar limiting grooves 4, and the top of the rebar support 1 is also provided with a bubble level 3.

[0024] Example 2

[0025] like Figure 1 , 2 As shown, the steel bar support 1 includes two vertical angle steels 11 arranged longitudinally. The top ends of the two vertical angle steels 11 are respectively connected to top angle steels 12 arranged in the front-back direction. The two top angle steels 12 are welded and fixed together by steel plate 2. The bubble level 3 is fixed on the upper surface of steel plate 2. The upper surface of the two top angle steels 12 is provided with steel bar limiting grooves 4 in the front-back direction.

[0026] Example 3

[0027] like Figure 1-3 As shown, the front end of the top angle steel 12 is welded and fixed to the upper end of the vertical angle steel 11, or the front end of the top angle steel 12 is hinged to the upper end of the vertical angle steel 11 through the hinge shaft 6. The hinged form makes it easy to adjust the tilt angle of the top of the bracket and facilitates folding. When welding, hold the end of the top angle steel with one hand and weld after reaching the required tilt angle.

[0028] Example 4

[0029] like Figure 1 , 2 As shown, the cross-section of the rebar limiting groove 4 is arc-shaped, and the inner diameter of the arc matches the outer diameter of the tie bar 10 to be welded.

[0030] like Figure 1 , 2 As shown, the inner surface of the rebar limiting groove 4 is also provided with an elastic body (not shown in the figure, which is a common technique for clamping rods, such as a rubber pad or an elastic metal sheet, the purpose of which is to fix the tie bar and prevent it from shifting during welding). The tie bar is tightly connected to the rebar limiting groove 4 through the elastic body.

[0031] Example 5

[0032] like Figure 1 , 2As shown, a guide groove 8 is welded between the two vertical angle steels 11 via a connecting plate 7. The guide groove consists of two opposing arc-shaped plates (see...). Figure 1 ) or a circular plate-like structure (see Figure 2 ).

[0033] like Figure 1 , 2 As shown, the handheld magnetic suction device 5 includes a handle and a cylindrical magnetic suction device fixedly connected to the front end of the handle. A fixing ring 9 is coaxially fixedly connected to the outer wall of the magnetic suction device. The fixing ring 9 cooperates with the top end of the guide groove 8 and is used to press the front end of the rebar support 1 against the surface of the embedded steel plate 13 when the magnetic suction device adsorbs the embedded steel plate 13 on the surface of the building structure. That is, when the magnetic suction device adsorbs the embedded steel plate, the front end of the rebar support is pressed against the surface of the embedded steel plate by the fixing ring squeezing the top of the guide groove.

[0034] like Figure 1 As shown, the cylindrical magnetic attraction device is a permanent magnet or an electromagnet. When it is an electromagnet, the handle is equipped with an electromagnet adjustment button.

[0035] The working principle of this new type:

[0036] like Figure 3 As shown, when using it, first place the front end of the rebar support against the surface of the embedded steel plate, adjust the posture of the rebar support to be horizontal (if it is a hinged rebar support, at least adjust the X-axis of the rebar support to be horizontal), then insert the handheld magnetic suction device 5 into the guide groove 5, and fix the rebar support to the embedded steel plate while adsorbing it. Then, clamp the two arms of the U-shaped tie bar 10 in the rebar limiting groove, and the front end of the tie bar abuts against the embedded steel plate. Weld the upper edge of the abutting point. After welding, remove the handheld magnetic suction device and the rebar support, and repair the lower edge of the contact part between the tie bar and the embedded steel plate by welding.
