Abstract

The present application relates to a device for measuring the deformation of an elastic support for supporting a bridge grating, and more particularly to a device for measuring the deformation of an elastic support for supporting a bridge grating, which comprises a base support; a lateral deformation measuring portion rotatably connected to the base support; and a vertical deformation measuring portion detachably connected to the base support.

Description

Technical Field

[0001] This invention relates to a device for measuring the deformation of an elastic support for a bracket. More specifically, it involves rotatably attaching the lateral deformation portion to a base support portion, and detachably attaching the lower part of the vertical deformation portion to the base support portion. This allows for the simultaneous measurement of the deformation of the elastic support height and the deformation angle of the lateral side, shortening the measurement time. Furthermore, it facilitates the mounting of the elastic support on the base support portion, thereby enabling the measurement of both the elastic support deformation and the lateral deformation of the base, making the measurement of the base more convenient. Background Technology

[0002] Typically, elastic supports are installed between the top slab and the piers of a bridge to transfer the load from the top slab to the piers and safely accommodate changes in the bridge deck caused by internal factors (such as self-weight sagging, concrete creep and drying shrinkage) and external factors (such as earthquakes, wind, and temperature changes).

[0003] In other words, elastic supports are designed to accept loads acting on the top slab, relative displacements caused by temperature changes or impacts such as wind and earthquakes, as well as shear displacements under horizontal loads, in order to maintain and ensure the safety of the bridge.

[0004] The deformation of these elastic bearings usually occurs with the passage of vehicles and changes in the surrounding environment, but if the deformation exceeds its allowable limit, cracks will appear in the bridge. Therefore, the deformation of the elastic bearings is measured regularly, and repairs and reinforcements are carried out before cracks appear in the bridge, compared with the allowable limit.

[0005] In other words, when the elastic support deforms within the elastic limit range, no special problems will occur. However, when the elastic support deforms beyond the elastic limit, it will lose its restoring force. In severe cases, the elastic support will tear and fail to support the bridge properly, resulting in structural problems for the bridge.

[0006] Therefore, the deformation of elastic bearings for bridges should be measured regularly. If an elastic bearing is found to be close to its elastic limit, it should be replaced or repaired.

[0007] In the past, to measure the deformation of elastic bearings, workers had to climb onto the bridge and use measuring tapes to measure the deformation. However, this method was not only difficult to measure the deformation of the elastic bearings accurately, but also inconvenient due to the safety equipment worn by the workers, resulting in extended working time.

[0008] The aforementioned invention refers to the background technology in the technical field to which this invention pertains, and not to conventional technology.

Figure 7 This is a partially enlarged cross-sectional view of the deformation measuring device for the support elastic bearing according to the present invention.

[0068] As shown in the figure, the deformation measuring device (10) for the support of the bracket of the present invention (hereinafter referred to as the "measuring device") is a measuring device (10) for measuring the deformation of the elastic support (300) of the support (200) of the bridge (100). The measuring device (10) of the present invention includes a base support (20), a side deformation measuring device (30), and a vertical deformation measuring device (40).

[0069] The basic support part (20) is composed of a support rod body (21) and a stable support part (22) formed by a stable support groove (221) on the upper part of the support rod body (21). The stable support groove (221) is formed at a certain interval on the upper part of the support rod body (21).

[0070] The support rod body (21) is composed of a rod structure and is made of synthetic resin or metal.

[0071] The aforementioned ground support groove (221) is formed at a certain distance along the length direction on the upper surface of the support rod body (21).

[0072] The main body (21) of the support rod is formed by a four-cornered rod shape.

[0073] The aforementioned side deformation side (30) is first connected to the base support (20) by a rotational hinge.

[0074] The side deformation measuring unit (30) consists of a side measuring tube assembly (31) and a side measuring tube assembly (32). The side measuring tube assembly (31) is connected to the ship end rotating hinge of the base support unit (20) and is partially clamped on the side measuring tube assembly (31).

[0075] The side measuring tube component (31) and the side measuring lead-out shaft (32) are made of metal or synthetic resin. The side measuring tube component (31) is composed of a circular or square tube structure, and the side measuring lead-out shaft (32) is composed of a circular or square shaft structure.

[0076] The deformable side (30) is connected to the inclined side of the elastic support (300) that is subjected to load deformation.

[0077] At this time, the above-mentioned side measurement output shaft (32) is taken out, and the upper part of the above-mentioned side measurement output shaft (32) is placed on the side of the above-mentioned elastic support (300).

[0078] By forming a stumbling block on the inner surface of the end of the side measuring tube member (31) and on the outer surface of one end of the side measuring output shaft (32), the side measuring output shaft (32) can also be prevented from separating from the side measuring tube member (31).

[0079] The side length and angle of the elastic support (300) deformed by the aforementioned side deformation side (30) can be measured.

[0080] Measurement scales can be formed on the outer surfaces of the side measuring tube component (31) and the side measuring output shaft (32).

[0081] The vertical deformable side (40) is connected to the upper rotating hinge of the side deformable side (30), and the lower part can be detached from the base support (20).

[0082] The vertical deformation measuring unit (40) consists of a vertical measuring tube component (41) detachable from the upper and lower parts of a stabilizing support (22) provided on the base support (20), and a rotatable vertical measuring shaft (42) that can be extracted from the upper and lower parts of the vertical measuring tube component (41) and is rotatable at the tower end of the side measuring shaft (32) of the side deformation measuring unit (30). The stabilizing support (221) is fixed to the stabilizing support (22) of the base support.

[0083] At this time, the vertical measuring tube component (41) will maintain the same vertical state as in the drawing, with its lower part clamped on the fixed support groove (221), thereby increasing the fixing force and support force of the vertical measuring tube component (41) and preventing it from moving during the measurement process.

[0084] The vertical measuring tube component (41) and the vertical measuring output shaft (42) are made of metal or synthetic resin. The vertical measuring tube component (41) is composed of a circular or square tube structure, and the vertical measuring output shaft (42) is composed of a circular or square shaft structure.

[0085] At this time, the vertical measurement output shaft (42) is pulled out so that the upper part of the vertical measurement output shaft (42) is located on the side of the elastic support (300) or connected to the bottom surface of the upper bracket (200).

[0086] A stumbling block is formed inside the upper part of the vertical measuring tube member (41) and outside the lower part of the side measuring output shaft (32), which can also prevent the vertical measuring output shaft (42) from separating from the vertical measuring tube member (41).

[0087] Measurement scales can be formed on the outer surfaces of the vertical measuring tube component (41) and the vertical measuring output shaft (42).

[0088] The height of the elastic support (300) deformed by the above-mentioned vertical deformation measuring unit (40) can be measured.

[0089] At this time, the staff took out the vertical measurement output shaft (42) after digging it out, and took out the side measurement output shaft (32) connected to the vertical measurement output shaft (42) together. Then, the upper part of the vertical measurement output shaft (42) was placed on the upper part of the deformable side of the elastic support (300) and the measurement was performed.

[0090] On the base support (20), the vibrator is further fixed to the outer surface by screws, and the vibration of the vibrator is transmitted to the side measuring tube component (31) through the base support (20). This prevents the side measuring tube component (31) from getting stuck when rotating. When the side measuring shaft (32) is pulled out, it prevents the inner surface of the side measuring tube component (31) from getting stuck. The deformation of the base (20) and the side (30) can reduce the time required for surface deformation or maintenance of the material, thereby reducing the cost of repairing the base (30).

[0091] Additionally, on the base support (20), a rotating bracket fastening screw is installed, one end of the rotating cylinder is connected to the hinge of the rotating cylinder, and the end of the moving shaft of the rotating cylinder is connected to the rotating hinge of the side deformation side (30). This allows the side measuring tube (31) to rotate under the drive of the rotating cylinder, making the deformation side of the elastic support (300) match the deformation side force and the side deformation side force, thus improving the contact between the side elastic support (300), elastic support force, and elastic support. This eliminates the need for an operator to support the measuring tube (31).

[0092] Furthermore, a bracket groove is further formed inside the fixed support groove (221) to rotate and clamp the ball bearing on the bearing groove, and to make a portion protrude and place it on the outside, thereby guiding the vertical measuring tube component (41) to clamp the fixed support groove (221) and preventing it from being stuck or rubbed by the fixed support groove (221) during signing and separation.

[0093] In addition, on the base support (20), one end of the elastic fitting washer spring is fastened to the screw, and the striking end of the elastic fitting washer spring is fastened to the side measuring tube member (31). By applying elastic pressure to the side measuring tube member (31) through the elastic fitting washer spring and supporting it, the elastic fitting force (300) with the side measuring tube member (31) can be increased, thereby increasing the static stability and static determinate force of the support member.

[0094] Furthermore, an elastic buffer plate made of elastic synthetic resin material can be attached and fixed to the bottom surface of the base support (20), and the bottom surface of the elastic buffer plate can be formed as a whole, so that the top surface of the pier where the elastic support (300) is located is rubbed and suspended, preventing the base support (20) from moving during the measurement process and preventing the transmission of elastic impact.

[0095] Additionally, in the aforementioned side deformation measuring unit (30), as shown in the figure, a side connecting bracket (50) is added or fixed with screws inside the side measuring tube component (31). In the side connecting bracket (50), a section of the side support coil spring (60) is fixed with screws. The striking end of the side support coil (60) is fixed by the side output shaft (32) input from the side measuring tube component (31) and by the side support spring (60). The side spring (32) is used to support the side output shaft (32) for measuring the aforementioned side measurement output shaft (32). When the shaft is extracted, the aforementioned side support coil spring (60) is stretched. After the measurement is completed by elasticity, the aforementioned side measurement output shaft (32) is returned to its original position.

[0096] In the vertical deformation measuring unit (40), the vertical connecting bracket (70) is further screwed inside the vertical measuring tube component (41). In the vertical connecting bracket (70), one end of the vertical support coil spring (80) is further screwed. The vertical support coil spring (80) is fixed to the lower part of the vertical measuring output shaft (42) in the vertical measuring tube component (41) by the elasticity of the vertical support coil spring (80). When the vertical measuring output shaft (42) is pulled out, the vertical support coil spring (80) will be stretched. After the elasticity completes the measurement, the vertical measuring output shaft (42) will be returned to its original position.

[0097] In addition, the elasticity of the aforementioned side support coil spring (60) and the aforementioned vertical support coil spring (80) buffers the transmission of impact.

[0098] The present invention has been described in detail above with reference to the drawings. However, the embodiments mentioned in this process are merely examples and are not intended to be limiting. Any component changes that can be uniformly addressed within the scope of the technical concept or field of the present invention provided in the following patent applications will fall within the scope of the present invention.
