Description

Technical Field

[0001] The utility model relates to the technical field of railway construction, in particular to a base plate limiting groove steel bar bending auxiliary device. Background Art

[0002] The slab track includes rails, fasteners, prefabricated track plates, intermediate plates and reinforced concrete base plates. During construction, it is necessary to reserve limiting grooves on the base plate of the ballastless track, then tie a flat steel mesh on top of the base plate, put U-shaped steel bars in the limiting grooves, bend them and connect them to the flat steel mesh, and then pour self-compacting concrete to form the intermediate plate. Due to site restrictions, ordinary electric bending machines cannot be used to bend the U-shaped steel bars, and they can only be done manually using a wrench. When the steel bars are bent manually, the forming error is large, and the base plate is used as a fulcrum, which can easily damage the concrete around the limiting groove. Summary of the invention

[0016] Figure 3 It is the use state of the utility model Figure 2 . DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0018] like Figure 1-3 As shown, the base plate limiting groove steel bar bending auxiliary device described in the utility model is composed of a first limiting member 1, a second limiting member 2 and a connecting member 3. The above-mentioned first limiting member 1 includes a first vertical plate 11 attached to the inner wall of the limiting groove M, and a first horizontal plate 12 is provided on the top of the first vertical plate 11 extending outward; the second limiting member 2 is arranged on the outside of the first limiting member 1, including a second vertical plate 21 whose bottom surface is connected to the base plate, and a second horizontal plate 22 is provided on the top of the second vertical plate 21 extending outward, and the second horizontal plate 22 is located above the radial steel bars or latitudinal steel bars of the plane steel mesh P; the connecting member 3 is arranged above the base plate, one end of which is connected to the outer wall of the first vertical plate 11, and the other end is connected to the inner wall of the second vertical plate 21.

[0019] Specifically, both the first limit member 1 and the second limit member 2 can be made of angle steel, and the good rigidity and strength of the angle steel are used to provide a reliable force point for the bending of the U-shaped steel bar 4. Usually, the first horizontal plate 12, as the fulcrum of the action of the wrench K, needs to be set lower than the second horizontal plate 22, so as to provide enough operating space for the wrench K; the second horizontal plate 22 is used to limit the bending of the U-shaped steel bar. After the U-shaped steel bar 4 is bent, it is abutted against the second horizontal plate 22, and the two are basically flush, which effectively prevents the U-shaped steel bar 4 from bending inadequately and bending beyond the design angle. Since the first limit member 1 is covered at the junction of the limit groove M and the top surface of the base plate, and the second limit member 1 is higher than the base plate and covered on the flat steel mesh P, direct contact between the wrench K and the concrete of the base plate is avoided, effectively protecting the concrete structure.

[0020] The above-mentioned connector 3 can adopt a telescopic structure, so as to adjust the relative position of the first limiter 1 and the second limiter 2 according to the on-site construction conditions (such as the depth of the limit groove M, the horizontal height and density of the plane steel mesh P, etc.), and then conveniently adjust the fulcrum position of the wrench K to adapt to the bending operation of the U-shaped steel bar 4 in various working conditions. Usually, the connector 3 is made of a threaded rod 31 and a threaded sleeve 32 that cooperate with each other. Among them, the threaded rod 31 is welded to the outer side wall of the first vertical plate 11, and the threaded sleeve 32 is welded to the inner side wall of the second vertical plate 21. The total length of the connector 3 is adjusted by screwing the threaded rod 31 or the threaded sleeve 32.

[0021] When in use, first adjust the length of the connecting member 3, and then set the first limiting member 1 close to the inner wall of the limiting groove M. At this time, the second limiting member 2 is connected to the radial steel bar or the latitudinal steel bar closest to the plane steel mesh P, and supported on the upper surface of the base plate; the wrench K is sleeved on the vertical section of the U-shaped steel bar 4 (see Figure 2 ), the vertical section is close to the inner side wall of the limiting groove M and extends upward from the bottom of the limiting groove M; then, the U-shaped steel bar 4 is bent with the first horizontal plate 12 of the first limiting member 1 as a fulcrum (see Figure 3 ); when the U-shaped steel bar 4 is close to the second horizontal plate 22 of the second limiter 2, it reaches the bending end point and completes the bending of the U-shaped steel bar 4; finally, the utility model is pulled out from the lower part of the steel bar, and then the wrench K is taken out from the U-shaped steel bar 4.

[0022] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
