Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a device for bending reserved steel bars of a bridge. Background Art

[0002] In modern bridge construction, steel bars, as one of the primary reinforcement materials, play a vital role in ensuring the stability and durability of bridge structures. The location and shape of the bars have a direct impact on the overall structural performance. During construction, it is often necessary to bend the bars at specific locations to connect structural components or to strengthen local structures.

[0003] For example, on the end faces of the diaphragms on both sides of the box beam, connecting steel bars are reserved for connecting adjacent diaphragms of the beam. The connecting steel bars are generally arranged in groups of two horizontal bars and are evenly arranged in the vertical direction of the diaphragms. When connecting the diaphragms of adjacent box beams, it is necessary to ensure that the groups of connecting steel bars on the two diaphragms are parallel to each other, and then use short-circuit steel bars to connect the connecting steel bars on adjacent diaphragms. Then use stirrups to cover the outside of the connected connecting steel bars. Finally, build a template around the above-mentioned steel bar structure, and cast the gap between adjacent diaphragms to complete the connection between the two.

[0004] However, in actual operation, due to design errors, manufacturing errors and construction errors, the connecting steel bars on two adjacent transverse partitions are often not parallel to each other. At this time, they need to be adjusted. The traditional method usually relies on manual bending, which is labor-intensive, has low work efficiency, and requires high physical strength from construction workers.

[0005] To this end, this application specifically proposes a bridge reserved steel bar bending device to solve the above technical problems. Utility Model Content

[0009] Furthermore, the clamping assembly includes a base plate, a first clamping plate fixedly arranged at one end of the base plate for abutting one side of the transverse partition, a second clamping plate slidably arranged at the other end of the base plate for abutting the other side of the transverse partition, and an adjustment assembly fixedly arranged at the other end of the base plate for adjusting the distance between the first clamping plate and the second clamping plate.

[0010] Furthermore, the limiting assembly includes two first connecting blocks fixedly arranged on the base plate and limiting columns symmetrically arranged on the first connecting blocks for abutting against the connecting steel bars.

[0011] Furthermore, the bending assembly includes two connecting plates hinged to the first connecting block at one end, a bending column symmetrically arranged on the connecting plate for abutting the connecting steel bars, a connecting rod hinged to the other ends of the two connecting plates at both ends, a second connecting block fixedly arranged on the base plate and located between the two first connecting blocks, and a handle hinged to the second connecting block at one end, and the handle body hinged to the connecting rod.

[0012] Furthermore, the hinge points between the two connecting plates and the connecting rod and the first connecting block form a parallelogram, and the line connecting the hinge points between the handle and the second connecting block and the connecting rod is parallel to a set of opposite sides of the parallelogram.

[0013] Furthermore, a slide groove is provided on the base plate, a slider is fixedly provided on the bottom end of the second clamping plate, and the slider is limitedly penetrated on the slide groove.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, the utility model provides a bridge reserved steel bar bending device, comprising:

[0027] The clamping assembly 1 is used to clamp the two sides of the diaphragm 2; the bending assembly 5 is hingedly provided on the clamping assembly 1 and is used to bend the connecting steel bar 4; the limiting assembly 3 is fixedly provided on the clamping assembly 1 and is used to abut the connecting steel bar 4 and limit its bending process. The clamping assembly 1 includes a base plate 101, a first clamping plate 102 fixedly provided at one end of the base plate 101 for abutting one side of the diaphragm 2, a second clamping plate 103 slidably provided at the other end of the base plate 101 for abutting the other side of the diaphragm 2, and an adjusting assembly 104 fixedly provided at the other end of the base plate 101 for adjusting the distance between the first clamping plate 102 and the second clamping plate 103. A slide groove 6 is provided on the base plate 101, and a slider 7 is fixedly provided at the bottom end of the second clamping plate 103, and the slider 7 is limited and penetrated on the slide groove 6.

[0028] During use, the adjustment component 104 is used to drive the second clamping plate 103 to slide along the slide groove 6, thereby adjusting the distance between the first clamping plate 102 and the second clamping plate 103 so that the distance is slightly larger than the thickness of the diaphragm 2, and then the clamping component 1 is clamped on both sides of the diaphragm 2 as the fixed point of the device. While clamping the clamping component 1, it is necessary to pay attention to inserting the connecting steel bars 4 that need to be bent into the limiting component 3 and the bending component 5 at the same time, and then bend the bending component 5 to make the connecting steel bars 4 bend around the limiting component 3, thereby completing the bending operation of the connecting steel bars 4.

[0029] In one embodiment, the limiting assembly 3 includes two first connection blocks 31 fixedly disposed on the base plate 101 and limiting columns 32 symmetrically disposed on the first connection blocks 31 for abutting against the connecting steel bars 4 .

[0030] With this design, when the clamping assembly 1 is clamped on the transverse partition 2, the connecting steel bar 4 is inserted between the two limiting columns 32 on the same first connecting block 31, so that no matter which side the connecting steel bar 4 is bent, the limiting column 32 can abut the connecting steel bar 4.

[0031] In one embodiment, the bending assembly 5 includes two connecting plates 51 hinged at one end to the first connecting block 31, a bending column 52 symmetrically rotatably disposed on the connecting plates 51 for abutting the connecting steel bar 4, a connecting rod 53 hinged at both ends to the other ends of the two connecting plates 51, a second connecting block 54 fixedly disposed on the base plate 101 and located between the two first connecting blocks 31, and a handle 55 hinged at one end to the second connecting block 54 and with the handle hinged to the connecting rod 53. The hinge points between the two connecting plates 51, the connecting rod 53, and the first connecting block 31 form a parallelogram, and the line connecting the handle 55 and the hinge points between the second connecting block 54 and the connecting rod 53 is parallel to a set of opposite sides of the parallelogram.

[0032] With this design, by bending the handle 55, the two connecting plates 51 can be simultaneously driven to deflect at the same angle, so that the connecting plates 51 drive the bending columns 52 to bend the connecting steel bars 4, thereby achieving the bending of two horizontal connecting steel bars 4 of the same group at one time, thereby improving the bending efficiency.

[0033] In one embodiment, the adjustment assembly 104 includes a mounting plate 1041 fixedly disposed at the other end of the base plate 101, a stud 1042 threadedly connected to the mounting plate 1041 and rotatably connected to the second clamping plate 103 at one end, and a handwheel 1043 fixedly disposed at the other end of the stud 1042.

[0034] In this design, by rotating the handwheel 1043, the stud 1042 is driven to screw in or out of the mounting plate 1041, thereby driving the second clamping plate 103 to move along the slide groove 6 under the limiting action of the slider 7, changing the distance between the first clamping plate 102 and the second clamping plate 103, so as to facilitate clamping of cross partitions 2 of different thicknesses.

[0035] In one embodiment, auxiliary support plates 8 are fixedly provided on the surfaces away from the first clamping plate 102 and the second clamping plate 103 . The auxiliary support plates 8 on the first clamping plate 102 are fixedly connected to the base plate 101 , and the auxiliary support plates 8 on the second clamping plate 103 are in contact with the base plate 101 .

[0036] With this design, when the first clamping plate 102 and the second clamping plate 103 are subjected to lateral force, they are less likely to deform or break due to the auxiliary support function of the auxiliary support plate 8, thereby enhancing the stability of the clamping connection with the diaphragm 2.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
