[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] A dual-type steel bar tying structure, combined Figure 1 , Figure 2 and Figure 3 As shown, it includes: a U-shaped buckle 1, a fixing plate 2 and a flexible pad 3; the U-shaped buckle 1 includes a U-shaped section 11 and two opposite step sections 12, the step sections 12 protrude to the inner side of the U-shaped section 11 to form a step surface 4; the flexible pad 3 is fixed along the inner side of the U-shaped section 11 and forms a "U" shape, and a gap is left between the end of the flexible pad 3 and the step surface 4; the fixing plate 2 includes two rotatably connected steel plates 21, and the two steel plates 21 are each provided with a through hole 22, the axes of rotation of the two steel plates 21 are parallel to the axes of the two through holes 22 or are skewed and perpendicular, and the aperture of the through hole 22 is larger than the size of the step section 12; the two steel plates 21 can be inserted between the end of the flexible pad 3 and the step surface 4 after being flush, and the two sides of the steel plate 21 are respectively abutted against the flexible pad 3 and the step surface 4.
[0024] When the glass fiber reinforcement 5 and the steel bar 6 are tied and overlapped, Figure 1 , Figure 2 and Figure 3 As shown, Figure 2The figure includes two schematic diagrams of two steel plates 21 being bent and flush. The U-shaped buckle 1 is passed through the glass fiber tendons 5 and the steel bars 6, and the two steel plates 21 are rotated so that the spacing between the two through holes 22 is reduced. Since the aperture of the through hole 22 is larger than the size of the step 12, the step 12 can easily pass through the through hole 22. The fixing plate 2 is put on the U-shaped buckle 1, and the steel plate 21 is pushed to squeeze the end of the flexible pad 3. Then, the two steel plates 21 are rotated until they are flush. The spacing between the two through holes 22 is increased so that the steel plate 21 is inserted between the end of the flexible pad 3 and the step surface 4. The steel plate 21 is fixed under the action of the end of the flexible pad 3 and the step surface 4, and the flexible pad 3 is squeezed and deformed by the steel plate 21. Under the restriction of the U-shaped section 11 and the steel plate 21, the flexible pad 3 is deformed toward the glass fiber tendons 5 and the steel bars 6; after deformation, the flexible pad 3 can fit the glass fiber tendons 5 and the steel bars 6 tightly, so that the flexible pad 3 hugs the glass fiber tendons 5 and the steel bars 6 to achieve a reliable connection between the two. The flexible pad 3 is in surface contact with the glass fiber tendons 5 and the steel bars 6, and the friction force is relatively large, which can prevent the glass fiber tendons 5 and the steel bars 6 from sliding relative to each other, and solve the problem of loose binding in the existing U-shaped buckle connection structure. The binding structure can also prevent the glass fiber tendons 5 and the steel bars 6 from moving relative to each other during the construction process, which can greatly facilitate installation; and the two steel plates 21 are bent and sleeved on the U-shaped buckle 1, and the two steel plates 21 are turned to be flush and fixed, so the installation is simpler and more efficient.
[0025] Preferably, the fixing plate 2 also includes a rotating component, and the axes of rotation of the two steel plates 21 are not in the same plane and perpendicular to the axes of the two through holes 22. The rotating component limits the rotation range of the two steel plates 21 to 0° to 180°, that is, it is ensured that the two steel plates 21 can rotate to be flush at most. During installation, the two steel plates 21 can be rotated outward, that is, it is ensured that the two steel plates 21 cannot rotate toward the side of the flexible pad 3 after being rotated to be flush, so as to avoid the two steel plates 21 from rotating slightly under the action of the flexible pad 3, thereby ensuring that the two steel plates 21 can reliably squeeze the flexible pad 3, ensuring that the flexible pad 3 has no rebound to achieve a close fit with the glass fiber reinforcement 5 and the steel bar 6, and ensuring that the binding is firm.
[0026] Preferably, the rotating component includes: a rotating shaft, a limiting plate 23, a first connecting plate and a second connecting plate; the rotating shaft is fixedly arranged on one side of the limiting plate 23, the axis of the rotating shaft is parallel to the limiting plate 23 and both ends of the rotating shaft extend out of the limiting plate 23; the first connecting plate and the second connecting plate are respectively rotatably connected to the rotating shaft, and the first connecting plate and the second connecting plate are respectively fixedly connected to the two steel plates 21. The first connecting plate and the second connecting plate realize the rotation of the two steel plates 21, and when the two steel plates 21 are rotated to be flush, the plane of the steel plate 21 abuts the limiting plate 23, and the limiting plate 23 restricts the two steel plates 21 from continuing to rotate, and the rotation range of the two steel plates 21 is limited to 0° to 180°.
[0027] Specifically, the steel plates 21 are two square steel plates of the same size, the rotation axis is located between the sides of the two steel plates 21, the first connecting plate and the second connecting plate are respectively welded and fixed on the two steel plates 21, the first connecting plate and the second connecting plate are provided with circular holes whose axes are parallel to the steel plates 21, and the first connecting plate and the second connecting plate are sleeved on the rotation axis. The first connecting plate and the second connecting plate can be located on the upper surface of the steel plate 21 or on the side of the steel plate 21. The limiting plate 23 is welded and fixed in the middle of the rotation axis and is located on the upper side of the steel plate 21. The two steel plates 21 are rotated to be flush, and the upper surfaces of the two steel plates 21 abut against the lower surface of the limiting plate 23, limiting the maximum rotation of the two steel plates 21 to be flush.
[0028] Specifically, the flexible pad 3 is a rubber strip, and the flexible pad 3 is adhered to the inner side of the U-shaped segment 11 by adhesive.
[0029] Preferably, the inner side of the U-shaped section 11 includes a semi-cylindrical surface 111 and two tangent planes 112, and the tangent planes 112 are tangent to the semi-cylindrical surface 111, which can increase the contact area with the flexible pad 3 and ensure the force-bearing area of the flexible pad 3 so that the flexible pad 3 can be fully deformed. In addition, the semi-cylindrical surface 111 and the two tangent planes 112 can also facilitate the pasting and fixing of the flexible pad 3.
[0030] Preferably, the area of the end face of the flexible pad 3 is larger than the area of the step surface 4, ensuring the contact area between the end face of the flexible pad 3 and the steel plate 21, thereby making the flexible pad 3 better deformed under pressure and ensuring that the flexible pad 3 fits tightly against the glass fiber reinforcement 5 and the steel bar 6 after deformation.
[0031] Preferably, combined Figure 2 , Figure 4 and Figure 5 As shown, a through groove 7 is provided on the outside of the U-shaped segment 11, and the through groove 7 is located in the middle of the U-shaped segment 11. The direction of the through groove 7 is perpendicular to the plane formed by the U-shaped segment 11. The dimension of the steel plate 21 in the direction perpendicular to the plane formed by the U-shaped segment 11 is smaller than the spacing between the two stage sections 12, that is, the width of the steel plate 21 is smaller than the spacing between the two stage sections 12, so that the steel plate 21 can be inserted between the two stage sections 12. The provision of the through groove 7 enables the cross-binding of the glass fiber reinforcement 5 and the steel bar 6 to be achieved through the two binding structures, so that the binding structure becomes a dual-type steel bar binding structure applicable to binding overlap and cross-binding.
[0032] When cross lashing:
[0033] First, pass the first U-shaped buckle 1 through the glass fiber ribs 5 and steel bars 6 arranged in a cross shape; bend the first fixing plate 2 and make the first limiting plate 23 face away from the steel bars 6, put the first fixing plate 2 on the first U-shaped buckle 1, rotate the two steel plates 21 of the first fixing plate 2 until they are flush, and complete the first fixing plate 2 being inserted between the end of the first flexible pad 3 and the first step surface 4.
[0034] Secondly, place the second U-shaped buckle 1 on the through groove 7 of the first U-shaped buckle 1, and the first U-shaped buckle 1 and the second U-shaped buckle 1 are in a cross shape. Since the second U-shaped buckle 1 is placed on the first U-shaped buckle 1, the step surface 4 of the second U-shaped buckle 1 is staggered with the step surface 4 of the first U-shaped buckle 1. Bend the second fixed plate 2 and make the second limiting plate 23 face the steel bar 6, and put the second fixed plate 2 on the second U-shaped buckle 1; the second fixed plate 2 first contacts the first limiting plate 23, and the second fixed plate 2 continues to push the first limiting plate 23 so that the first fixed plate 2 continues to squeeze the first flexible pad 3, and the first fixed plate 2 is separated from the first step surface 4; continue to push the second fixed plate 2 until the second flexible pad 3 is squeezed, and rotate the two steel plates 21 of the second fixed plate 2 until they are flush, so that the second fixed plate 2 is inserted between the end of the second flexible pad 3 and the second step surface 4.
[0035] Since the first fixing plate 2 is subjected to the thrust of the second fixing plate 2 , the first limiting plate 23 and the second limiting plate 23 can limit the rotation of the first fixing plate 2 and the second fixing plate 2 after being relative to each other, thereby ensuring a stable and reliable connection.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described 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 solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
