Description

Technical Field

[0001] The utility model relates to the technical field of U-shaped steel manufacturing, and specifically relates to a U-shaped steel anti-falling beam structure. Background Art

[0002] The U-shaped steel anti-falling beam is mainly used on bridges to prevent the upper structure of the bridge from falling due to external forces such as earthquakes, wind loads, vehicle loads, etc., and to mitigate the impact damage to other falling beam devices during earthquakes.

[0003] On the other hand, the U-shaped steel anti-falling beam must be used together with the bearing. It can be used in cooperation with the bearing as a separate U-shaped steel anti-falling beam device, or integrated with the bearing as a U-shaped steel element.

[0004] The U-shaped steel anti-falling beam must be used together with the bearing. It can be used in cooperation with the bearing as a separate U-shaped steel anti-falling beam device, or integrated with the bearing as a U-shaped steel element; the U-shaped steel anti-falling beam is mainly installed together with the bearing between the beam bottom and the pier top cushion stone.

[0005] Furthermore, whether used in cooperation with the bearing or integrated with the bearing, each U-shaped steel needs to correspond to a different type of bearing; in the case of a sloping beam body, the U-shaped steel also needs to be slope-adjusted accordingly; however, on a single span beam, the U-shaped steel is symmetrically installed, and at this time, the U-shaped steel has two slope-adjusting structures.

[0006] Generally, there are 4 types of bearing types, namely fixed type, longitudinal movement type, lateral movement type, and multi-directional movement type, and there are 2 types of slope-adjusting structures for U-shaped steel; therefore, in fact, there are a total of 4*2 = 8 forms of the combined use method of U-shaped steel and the bearing.

[0007] The prior art does not distinguish and identify during the manufacturing process of U-shaped steel, or only simply marks the model of U-shaped steel, and there is no more reference information.

[0008] The defects of the prior art are as follows:

[0009] 1. In engineering, the installation height between the beam bottom and the pier top cushion stone is often not sufficient, resulting in very difficult installation and removal of bolts for many U-shaped steels due to insufficient installation height.

[0010] 2. With so many combination forms, it is very easy to have problems of incorrect matching between the U-shaped steel and the bearing during the processes of production, assembly, transportation, and installation;

[0011] 3. The appearance of U-shaped steel anti-falling beam devices of different models may be very similar and difficult to distinguish, which will further increase the probability of incorrect matching between the U-shaped steel and the bearing.

[0012] In summary, how to distinguish U-shaped steel during processing and production so that workers can tell whether the U-shaped steel has a slope, what the model and slope of the U-shaped steel are; at the same time, during installation, workers can clearly distinguish the type of bearing used in conjunction with the U-shaped steel anti-falling beam device, and can also distinguish on what slope the U-shaped steel anti-falling beam device is applied to ensure the correct assembly of the device, which is a technical problem that has not been solved yet.

[0059] The present invention is further illustrated below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0060] like Figure 1a to Figure 1b As shown, a U-shaped steel anti-fall beam structure comprises a U-shaped steel 2, a beam bottom embedded component 1, and a lower support plate 3; wherein:

[0061] The upper end of the U-shaped steel 2 is provided with multiple upper bolt holes 4, and the lower end is provided with multiple lower bolt holes 5; the upper bolt holes 4 are used to bolt the upper end of the U-shaped steel 2 to the embedded component 1 at the bottom of the beam, and pass through the upper end of the U-shaped steel 2; the lower bolt holes 5 are used to bolt the lower end of the U-shaped steel 2 to the lower support plate 3, and pass through the lower end of the U-shaped steel 2.

[0062] like Figure 2a to Figure 2b As shown, a recessed groove 6 is provided on the inner side of the upper end of the U-shaped steel 2, from the upper bolt hole 4 to the edge of the inner U-shaped opening direction of the upper end of the U-shaped steel 2; the width of the recessed groove 6 is not less than the diameter of the upper bolt hole 4; the thickness of the steel plate above the recessed groove 6 is less than the thickness of the steel plate at the upper end of the U-shaped steel 2.

[0063] like Figure 2a to Figure 2b As shown, a recessed groove 6 is provided on the inner side of the lower end of the U-shaped steel 2, from the lower bolt hole 5 to the inner edge of the U-shaped opening direction of the lower end of the U-shaped steel 2; the width of the recessed groove 6 is not less than the diameter of the lower bolt hole 5; the thickness of the steel plate below the recessed groove 6 is less than the thickness of the steel plate at the lower end of the U-shaped steel 2.

[0064] The upper bolt hole 4 and the lower bolt hole 5 are staggered in the vertical direction.

[0065] As Figure 3 shown, it should be noted that for the conventional U-shaped steel 2, the installation and removal of bolts are difficult due to the limited height.

[0066] As Figure 4 shown, therefore, in the present utility model, by processing the sinking groove 6 and staggering the upper bolt hole 4 and the lower bolt hole 5 of the U-shaped steel 2, the installation and removal space of the bolts of the U-shaped steel 2 can be increased without changing the height of the internal space of the U-shaped steel 2.

[0067] As Figure 2a to Figure 2b shown, in this specific embodiment, the sinking groove 6 has two forms: an independent sinking groove 6a and a combined sinking groove 6b.

[0068] When the sinking groove 6 is an independent sinking groove 6a, each independent sinking groove 6a uniquely corresponds to an upper bolt hole 4 or a lower bolt hole 5.

[0069] The independent sinking groove 6a vertically points to and penetrates the edge of the inner U-shaped opening direction of the U-shaped steel 2.

[0070] When the sinking groove 6 is a combined sinking groove 6b, the combined sinking groove 6b is rectangular.

[0071] One side edge of the combined sinking groove 6b is arranged between the upper bolt hole 4 or the lower bolt hole 5 closest to one side of the U-shaped steel 2 and this side of the U-shaped steel 2, and vertically points to and penetrates the edge of the inner U-shaped opening direction of the U-shaped steel 2.

[0072] In this specific embodiment, the other side edge of the combined sinking groove 6b is arranged between the upper bolt hole 4 or the lower bolt hole 5 closest to the other side of the U-shaped steel 2 and this side of the U-shaped steel 2, and vertically points to and penetrates the edge of the inner U-shaped opening direction of the U-shaped steel 2.

[0073] The third side edge of the combined sinking groove 6b is arranged between the upper bolt hole 4 or the lower bolt hole 5 and the bending part of the U-shaped steel 2, and is parallel to the inner U-shaped opening direction of the U-shaped steel 2.

[0074] As Figure 5a to Figure 5b shown, in this specific embodiment, the sinking groove 6 can also be divided into a first-level sinking groove 6c and a second-level sinking groove 6d according to the depth; among them: the depth of the first-level sinking groove 6c is less than that of the second-level sinking groove 6d.

[0075] The beam bottom embedded component 1 is provided with bolt holes; the specifications and opening positions of the bolt holes on each beam bottom embedded component 1 match the upper bolt holes 4 at the upper end of the U-shaped steel 2 that needs to be bolt-connected to this beam bottom embedded component 1.

[0076] The lower support plate 3 is provided with bolt holes; the specifications and opening positions of the bolt holes on each lower support plate 3 match the lower bolt holes 5 at the lower ends of the U-shaped steel 2 that needs to be bolt-connected to this lower support plate 3.

[0077] As Figure 6 shown, the U-shaped steel 2 includes sloped U-shaped steel and non-sloped U-shaped steel; at positions on the sloped U-shaped steel that do not affect the structural performance, there are no less than 1 process holes 7 for identifying the U-shaped steel 2 as sloped U-shaped steel; all the process holes 7 on the same sloped U-shaped steel have exactly the same hole shape.

[0078] In this specific embodiment, the shapes of the process holes 7 include circular, square, and diamond.

[0079] It should be noted that the purpose of punching the process holes 7 is to distinguish between sloped U-shaped steel and non-sloped U-shaped steel during the production and processing period; in this way, as long as there are process holes 7 seen coming off the production line, it must be sloped U-shaped steel; otherwise, it must be non-sloped U-shaped steel.

[0080] It should be further noted that the shape of the process holes 7 is not fixed and can be circular, square, or diamond, but the shape of the process holes 7 on each U-shaped steel 2 must be kept consistent.

[0081] Near the process hole 7, there is a permanent identification code for the U-shaped steel 2 where this process hole 7 is located.

[0082] In this specific embodiment, the content of the permanent identification code includes the slope size, the type of the support that cooperates with this U-shaped steel 2, and the slope adjustment direction; among them: the slope size, the support type, and the slope adjustment direction are all identified using an artificially preset symbol system.

[0083] It should be noted that the process for punching the permanent identification code on the outer surface of the U-shaped steel 2 includes a steel stamping process.

[0084] It should be noted that in addition to the steel stamping process, other processes can also be used to punch the permanent identification code.

[0085] On the U-shaped steel 2, there is a unique U-shaped steel code for this U-shaped steel 2; the U-shaped steel code is used to trace the production process of the corresponding U-shaped steel 2.

[0086] In this specific embodiment, the U-shaped steel code includes the specific U-shaped steel model, slope size, slope direction, production number, production unit, and usage project of the corresponding U-shaped steel 2.

[0087] It should be noted that after the processing of the U-shaped steel 2 is completed, the U-shaped steel code should be punched in time to represent the uniqueness of this U-shaped steel 2.

[0088] It should be further explained that the purpose of marking the U-shaped steel with a code before painting is to distinguish the specific U-shaped steel 2 in the process flow before painting so as to avoid confusion.

[0089] In this specific embodiment, the U-shaped steel code remains clearly visible after the paint coating process is completed.

[0090] On the outer surface of the paint coating of the sloped U-shaped steel, there is also a slope mark about the sloped U-shaped steel; the slope mark includes the corresponding slope size and uphill direction of the sloped U-shaped steel.

[0091] It should be noted that the purpose of setting the slope mark is to further reflect the uphill direction and slope size of the U-shaped steel 2. Therefore, the slope mark must be placed in a conspicuous place on the outer surface of each U-shaped steel 2. Doing so also has an additional benefit, which is that it can accurately match the beam body with the corresponding slope and is easy to install.

[0092] It should be noted that the support model should also be marked at a conspicuous position on the outer surface of the U-shaped steel 2.

[0093] It should be further explained that the purpose of marking the complete support model of the support used in conjunction with the U-shaped steel 2 is to prevent the U-shaped steel anti-falling beam device from being mistakenly modeled during installation, thereby affecting the progress of the project.

[0094] like Figure 7 As shown, in this specific embodiment, if the U-shaped steel anti-falling beam device using sloped U-shaped steel adopts a symmetrical structural design, the opening positions of each group of process holes 7 on each pair of sloped U-shaped steels at the corresponding positions are symmetrically arranged on their respective sloped U-shaped steels and are opened on the same side direction.

[0095] In this specific embodiment, if the U-shaped steel anti-falling beam device using sloped U-shaped steel adopts a symmetrical structural design, then each corresponding group of uphill directions on each pair of sloped U-shaped steels at corresponding positions point to the same direction.

[0096] It should be noted that the purpose of the marking method and the method of opening the process hole 7 in this special case is to ensure correct assembly.

[0097] In order to further demonstrate the use of the utility model, this specific embodiment also shows the following Figure 8a to Figure 8b The usage of another U-shaped steel anti-fall beam structure shown in actual construction is consistent with the aforementioned usage in principle, which can reflect the high adaptability and adjustability of the utility model, as well as the wider application range brought about by it.
