Vault corrugated steel box culvert

Abstract

The utility model relates to a vault corrugated steel box culvert. Most of existing corrugated steel box culverts are rectangular, the internal capacity is small, stress on the tops of the box culverts is concentrated and not prone to dispersion, and therefore when the bearing capacity of the tops of the box culverts is too high, corrugated steel on the tops of the box culverts is prone to breakage. The box culvert comprises a side wall part and an arc top part located above the side wall part, the arc top part comprises at least one arc-shaped corrugated plate, and the arc-shaped corrugated plate arches towards the outer side of the box culvert; the side wall part comprises two groups of parallel and opposite vertical corrugated plate walls, the vertical corrugated plate walls are vertically arranged on the bearing platform, and the two ends of the arc-shaped corrugated plate are fixedly connected with the two groups of vertical corrugated plate walls through arc plate connecting pieces respectively. According to the utility model, by arranging the arc-shaped corrugated plate which arches upwards, the top is arched, so that the capacity is increased, and the stress on the top is dispersed and is not easy to concentrate due to the radian of the arc-shaped corrugated plate.

Description

Technical Field

[0001] This utility model relates to the field of box culvert technology, specifically to an arched corrugated steel box culvert. Background Technology

[0002] Box culverts are a type of culvert, which can be divided into slab culverts, pipe culverts, arch culverts, and box culverts. Box culverts are not open channels with slab covers. The cover, body, and foundation of a box culvert are a whole constructed of reinforced concrete and can be used for drainage, pedestrian passage, and vehicle passage.

[0003] In existing technologies, box culvert structures are generally made of reinforced concrete, but concrete box culverts have long construction cycles and poor deformation capacity. Compared with traditional concrete box culvert structures, corrugated steel plate box culverts have significant advantages: strong load-bearing capacity, strong deformation adaptability; short construction period, convenient construction, and low cost.

[0004] However, most of the current corrugated steel box culverts are rectangular. Rectangular box culverts have a small internal capacity and their tops are made of straight corrugated steel, which causes the stress on the top of the box culvert to be concentrated and not easily dispersed. As a result, when the load on the top of the box culvert is too high, the corrugated steel at the top is prone to breakage. Summary of the Invention

[0005] The purpose of this invention is to provide an arched corrugated steel box culvert to at least solve the problems of small internal capacity and concentrated stress at the top of existing corrugated steel box culverts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An arched corrugated steel box culvert includes a side wall portion and an arc-shaped top portion located above the side wall portion. The arc-shaped top portion includes at least one arc-shaped corrugated plate, which arches outward from the box culvert. The side wall portion includes two sets of parallel and opposing vertical corrugated plate walls, which are vertically arranged on a bearing platform. The two ends of the arc-shaped corrugated plate are fixedly connected to the two sets of vertical corrugated plate walls respectively through arc plate connectors.

[0008] Furthermore, the lower ends of the two sets of vertical corrugated wall panels are connected to horizontal connecting plates, and the vertical corrugated wall panels and the horizontal connecting plates are fixed by fixed support members.

[0009] Furthermore, the arc plate connector includes multiple clamping plates and multiple bolts. The lower end of the arc top abuts against the upper end of the vertical corrugated plate wall, and the arc top is aligned with the crests and troughs of the vertical corrugated plate wall. The clamping plates are fixed to the outer and inner sides of the arc top and the vertical corrugated plate wall respectively by the bolts. The abutment point between the arc top and the vertical corrugated plate wall is located between the inner and outer clamping plates.

[0010] Furthermore, the clamping plate is made of corrugated steel plate, and the waveform of the clamping plate matches the waveform of the arc top and the side wall portion. The clamping plate includes an integrally formed straight section and an arc section, which are tightly fitted to the side wall portion and the arc top portion, respectively.

[0011] Furthermore, the arc plate connector includes a lower connecting plate and a plurality of bolts. The lower connecting plate extends vertically to the lower end of the arc top. The upper end of the vertical corrugated plate wall is tangent to the outer side of the lower connecting plate and forms an overlapping portion with the lower connecting plate. The arc top and the vertical corrugated plate wall are fixed together by the bolts passing through the overlapping portion.

[0012] Furthermore, the upper end of the vertical corrugated wall plate is aligned with the upper end of the lower connecting plate, and both are at the same height as the center of the arc top.

[0013] Furthermore, the arc plate connector includes an upper connecting plate and multiple extended double-headed bolts. The upper connecting plate extends vertically to the upper end of the vertical corrugated plate wall. The lower end of the arc top is tangent to the inner side of the upper connecting plate and forms a gap with the upper connecting plate. The arc top and the vertical corrugated plate wall are fixed together by the extended double-headed bolts passing through the gap.

[0014] Furthermore, the transverse connecting plate is anchored to the bearing platform via anchor bolts.

[0015] Furthermore, the vertical corrugated wall is connected by overlapping corrugated steel plates in sequence.

[0016] Furthermore, the fixed support includes a supporting angle steel and a plurality of bolts. The supporting angle steel is located on the outside of the vertical angle at the intersection of the vertical corrugated wall and the horizontal connecting plate, and the supporting angle steel is fixed to the vertical corrugated wall and the horizontal connecting plate by the bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model sets the corrugated plate on the top of the box culvert as an upward-arching arc-shaped corrugated plate, so that the top is arched, which increases the internal space and thus increases the capacity. In addition, the curvature of the arc-shaped corrugated plate disperses the force on the top, making it less likely to concentrate, thereby improving the load-bearing capacity and making the top of the box culvert less prone to breakage.

[0019] 2. This utility model can further improve the load-bearing capacity of the vertical corrugated wall and the horizontal connecting plate by fixing the supporting angle steel on the outside of the vertical angle at the intersection of the vertical corrugated wall and the horizontal connecting plate.

[0020] 3. In one embodiment of this utility model, the arc-shaped corrugated plate and the vertical corrugated plate wall are clamped between two clamping plates, thereby fixing the arc-shaped corrugated plate and the vertical corrugated plate wall, making the reinforcement convenient and reliable, and possessing strong mechanical strength, so that the arc-shaped corrugated plate and the vertical corrugated plate wall are not prone to loosening.

[0037] Example 1:

[0038] like Figure 1 As shown, this embodiment provides an arched corrugated steel box culvert, including a side wall and an arc-shaped top located above the side wall. In this embodiment, the arc-shaped top is an arc-shaped corrugated plate 2, which is semi-circular and arches outward from the box culvert. The side wall consists of two sets of parallel and opposing vertical corrugated plate walls 3, which are connected by several corrugated steel plates overlapping each other. The two sets of vertical corrugated plate walls 3 are at the same height and are vertically set on the bearing platform 1. The top of the box culvert is set as an upward-arching arc-shaped corrugated plate 2, making the top of the box culvert arched, which increases the internal space and thus increases the capacity. Furthermore, the curvature of the arc-shaped corrugated plate 2 disperses the force on the top, making it less likely to concentrate, thereby improving the bearing capacity and making the top of the box culvert less prone to breakage.

[0039] In this embodiment, the lower ends of the two sets of vertical corrugated wall panels 3 are connected to horizontal connecting plates 4. The two ends of the arc-shaped corrugated plate 2 form obtuse angles with the vertical corrugated wall panels 3, and the vertical corrugated wall panels 3 form right angles with the horizontal connecting plates 4.

[0040] Furthermore, the two ends of the arc-shaped corrugated plate 2 are fixedly connected to two sets of vertical corrugated plate walls 3 respectively through arc plate connectors, and the vertical corrugated plate walls 3 are fixedly connected to the horizontal connecting plate 4 respectively through fixed support members.

[0041] like Figure 3 and 4 As shown, the arc plate connector includes two clamping plates 5 and multiple bolts 6. The lower end of the arc-shaped corrugated plate 2 abuts against the upper end of the vertical corrugated plate wall 3, and the crests and troughs of the arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3 are aligned. The clamping plates 5 are two pieces of steel corrugated plates, and the width of the corrugated plates is the same as the width of the arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3. In other embodiments, the clamping plates 5 can also be flat plates. The waveform of the clamping plates 5 matches the waveform of the arc top and the side wall. The clamping plates 5 include an integrally formed straight section and an arc section, which are tightly fitted to the side wall and the arc top, respectively. The clamping plates 5 are fixed to the arc-shaped corrugated plate wall 3 by bolts 6. The outer and inner sides of the corrugated plate 2 and the vertical corrugated plate wall 3 are connected, and the contact points between the curved corrugated plate 2 and the vertical corrugated plate wall 3 are located between the inner and outer clamping plates 5. The two clamping plates 5 are aligned, and the troughs of the clamping plates 5 are respectively embedded in the troughs of the curved corrugated plate 2 and the vertical corrugated plate wall 3. The crests of the clamping plates 5 respectively cover the crests of the curved corrugated plate 2 and the vertical corrugated plate wall 3. The upper ends of the clamping plates 5 are respectively tightly attached to the inner and outer sides of the curved corrugated plate 2, and the lower ends of the clamping plates 5 are respectively tightly attached to the inner and outer sides of the vertical corrugated plate wall 3, thereby fixing the curved corrugated plate 2 and the vertical corrugated plate wall 3 between the two clamping plates 5.

[0042] Several bolt holes are respectively opened on the crests and troughs of the two clamping plates 5. Several corresponding bolt holes are opened on the crests and troughs of the arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3 respectively. The bolts 6 are passed through the corresponding bolt holes and fixed with nuts, thereby fixing the clamping plates 5 to the outer and inner sides of the arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3 respectively, thus fixing the arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3.

[0043] Furthermore, such as Figure 2 As shown, the fixed support includes a support angle steel 7 and multiple bolts 6. The support angle steel 7 is located on the outside of the vertical angle at the intersection of the vertical corrugated wall 3 and the horizontal connecting plate 4, and is fixed to the vertical corrugated wall 3 by the bolts 6. The support angle steel 7 and the horizontal connecting plate 4 are also fixed to the bearing platform 1 by the bolts 6, thereby fixing the vertical corrugated wall 3 and the horizontal connecting plate 4 to the bearing platform 1. By placing the support angle steel 7 on the outside, the bearing capacity of the vertical corrugated wall 3 and the horizontal connecting plate 4 can be further improved.

[0044] The transverse connecting plate 4 is anchored to the bearing platform 1 in the middle by anchor bolts.

[0045] In this embodiment, bolt 6 is an M24 high-strength bolt, and nut is an M24 high-strength nut.

[0046] Example 2:

[0047] In this embodiment, as Figures 5-7 As shown, the arc plate connector includes a lower connecting plate and multiple bolts 6. The lower connecting plate extends vertically and integrally from the lower end of the arc-shaped corrugated plate 2. The lower connecting plate is a corrugated plate with the same width as the arc-shaped corrugated plate 2. The upper end of the vertical corrugated plate wall 3 is tangent to the outer side of the lower connecting plate and forms an overlapping part with the lower connecting plate. The arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3 are fixed together by bolts 6 passing through the overlapping part. The upper end of the vertical corrugated plate wall 3 is aligned with the upper end of the lower connecting plate and is at the same height as the center of the arc-shaped corrugated plate 2.

[0048] The curved corrugated plate 2, the lower connecting plate, and the vertical corrugated plate wall 3 are aligned with each other at their crests and troughs. The troughs of the vertical corrugated plate wall 3 are embedded in the troughs of the lower connecting plate, and the crests of the vertical corrugated plate wall 3 cover the crests of the lower connecting plate. Several corresponding bolt holes are opened on the crests and troughs of the overlapping parts of the lower connecting plate and the vertical corrugated plate wall 3. The bolts 6 are passed through the corresponding bolt holes and fixed with nuts, thereby fixing the curved corrugated plate 2 and the vertical corrugated plate 3.

[0049] The remaining working process and principles are the same as in Example 1.

[0050] Example 3:

[0051] In this embodiment, as Figures 8-10 As shown, the arc plate connector includes an upper connecting plate and multiple extended double-headed bolts. The upper connecting plate extends vertically and integrally to the upper end of the vertical corrugated plate wall 3. The arc-shaped corrugated plate 2 is semi-circular, and the lower end of the arc-shaped corrugated plate 2 is tangent to the inner side of the upper connecting plate, forming a gap between it and the upper connecting plate. The gap gradually increases from bottom to top. The arc-shaped corrugated plate 2 and the vertical corrugated plate wall 3 are fixed together by the extended double-headed bolts passing through the gap. The lower end of the arc-shaped corrugated plate 2 is aligned with the lower end of the upper connecting plate, and both are at the same height as the center of the arc-shaped corrugated plate 2.

[0052] The curved corrugated plate 2, the upper connecting plate, and the vertical corrugated plate wall 3 are aligned with each other. The trough of the upper connecting plate is embedded in the trough of the curved corrugated plate 2, and the peak of the upper connecting plate covers the peak of the curved corrugated plate 2. Several corresponding bolt holes are opened on the corresponding peaks and troughs of the curved corrugated plate 2 and the upper connecting plate on both sides of the gap. The extended double-headed bolts are passed through the corresponding bolt holes and fixed with nuts on both sides of the extended double-headed bolts, thereby fixing the curved corrugated plate 2 and the vertical corrugated plate 3.

[0053] The remaining working process and principles are the same as in Example 1.

[0054] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
