Description

Technical Field

[0001] The invention relates to the technical field of spiral ramps, in particular to a special-section weathering steel bending and torsion assembly for spiral ramps. Background Art

[0002] A spiral ramp is an inclined passage with a spiral curve as its path. It is widely used in scenarios such as building transportation (such as underground garages and large venues), landscape design (such as observation decks), and industrial facilities. Its core function is to solve the vertical transportation problem between different elevations while taking into account space utilization efficiency and visual aesthetics.

[0003] Most of the existing spiral ramps are cast in concrete, and the concrete casting method requires on-site formwork casting to achieve overall formation, which is more dependent on the stress of the steel skeleton. At the same time, it takes a certain amount of time to dry after casting before it can be used. As a result, the construction period of the threaded ramp built by the existing concrete casting method is long, and it cannot be completed and opened to traffic in a short time. To address the above problems, the present invention has developed a special-section weathering steel bending and torsion assembly for spiral ramps to solve the problem of long concrete construction period. Summary of the Invention

[0004] In order to overcome the shortcomings raised in the above background technology, the technical problem is to provide a special-section weathering steel bending-torsion assembly for a spiral ramp.

[0005] The technical solution is: a special-section weathering steel bending and torsion assembly for a spiral ramp, comprising a column, a welded connector for installation pre-embedded on the column, a large guardrail provided on one side of the welded connector, the large guardrail being welded to the corresponding welded connector, and the facing contact surfaces of multiple sections of the large guardrail being installed by welding, the side wall of the large guardrail being provided with a second box body, the lower part of the side wall of the second box body being welded with a bottom panel, the top of the bottom panel being welded with a lower strip, the upper part of the side wall of the second box body being welded with a tread panel, the bottom of the tread panel being welded with an upper strip, multiple groups of transversely arranged longitudinal stiffeners are welded between the bottom panel and the tread panel, the side walls of the longitudinal stiffeners are welded with transverse strips, multiple groups of transverse stiffeners arranged along the transverse length of the ramp are welded between the bottom panel and the tread panel, a first box body is fixedly connected between the end faces of the bottom panel and the tread panel, and a small guardrail is welded on the top of the first box body to serve as a kickboard to prevent objects from falling and causing unnecessary injuries.

[0006] Furthermore, the second box body is assembled by three second flange plates, and the three second flange plates are welded into a U shape and welded to the large railing. A partition plate is welded between the second flange plate and the large railing on one side, and a first stiffening plate is welded between the second flange plate and the large railing on one side.

[0007] Furthermore, the structure of the bottom panel is a ramp bottom laid obliquely, which is used to withstand bending moment forces and resist structural deflection.

[0008] Furthermore, the tread plate is laid on the top surface of the ramp and is mounted on the longitudinal stiffener and the transverse stiffener.

[0009] Furthermore, when the transverse stiffener encounters a longitudinal stiffener and the transverse stiffeners that are disconnected in the same direction, the disconnection points must be on the same straight line to ensure uniform force. The transverse stiffeners are mainly used to enhance the stiffness and stability of the ramp.

[0010] Furthermore, the first box body is assembled from four first flange plates, one above the other and one below the other, and an inner partition plate is welded between the upper and lower first flange plates.

[0011] Furthermore, the longitudinal stiffener and upper strip are welded by intermittent welding to reduce welding deformation of the components.

[0012] Furthermore, a guardrail top side sealing plate is welded to the upper part of the side wall of the large guardrail, an inner stiffening plate welded to the large guardrail is welded to the bottom of the guardrail top side sealing plate, and a guardrail inner web is added and welded to one side of the large guardrail, and a plug welding groove is opened on the guardrail inner web.

[0013] Furthermore, the cross section of the spiral ramp is trapezoidal, and the side with a larger contact area is welded to the embedded part on the column.

[0014] The beneficial effects are as follows: the present invention is simpler to operate than the traditional concrete pouring method by welding and assembling steel structural parts for gradual installation, and does not require on-site formwork and casting, which facilitates rapid construction and reduces construction period. In addition, the steel structure method has lower requirements on the foundation bearing capacity and smaller dead weight than the concrete casting method, and is easier to adjust the shape and modify than the cast steel structure method, and can reduce the generation of construction waste during subsequent renovation or demolition. At the same time, because the cross-section of the spiral ramp is trapezoidal, and the side with a large contact area is welded and installed with the embedded parts on the column, the center of gravity of the spiral ramp can be located close to the column side, which makes the spiral ramp more stable while increasing its load capacity.

DETAILED DESCRIPTION

[0027] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0028] A special-section weathering steel bending and torsion assembly for spiral ramps, such as Figures 1-11 As shown, it includes a column 12, and a welding connector for installation is embedded on the column 12. A large fence 9 is provided on the outside of the column 12. The large fence 9 is installed in a multi-segment manner, and the structure after the multi-segment large fence 9 is installed is spirally arranged. The large fence 9 is welded and installed with the welding connector on the column 12. The segmented installation method is convenient for installation through a lifting device, and the contact surfaces of the opposite sides of the multi-segment large fence 9 are installed by welding, so that the multi-segment large fence 9 after welding is in a spiral structure. The side wall of the large fence 9 is provided with a second box 10, and the second box 10 is assembled by three second flange plates 101 (as shown in FIG. Figure 7The structure shown in FIG, and the three second flange plates 101 are welded into a U shape and welded to the large guardrail 9. The position between the second flange plate 101 on one side and the large guardrail 9 is welded with a spaced partition 102. The position between the second flange plate 101 on one side and the large guardrail 9 is welded with a first stiffening plate 103. The upper part of the side wall of the large guardrail 9 is welded with a guardrail top side sealing plate 104. The bottom of the guardrail top side sealing plate 104 is welded with an inner stiffening plate 10 welded to the large guardrail 9. 5. The side wall of the guardrail top side cover 105 is welded with the guardrail inner web 106 welded with the cover plate 104. The guardrail inner web 106 is provided with a plug welding notch 107. The lower part of the side wall of the second box body 10 is welded with the bottom panel 4. The structure of the bottom panel 4 is an obliquely laid ramp bottom, which is used to withstand the bending moment force and resist the deflection of the structure. The top of the bottom panel 4 is welded with the lower strip 8. The upper part of the side wall of the second box body 10 is welded with the tread panel 3. The bottom of the tread panel 3 is welded with the bottom of the tread panel 3. The top of the ramp is welded with an upper strip 5, and multiple groups of transverse stiffening plates 7 are welded between the bottom panel 4 and the tread panel 3. The side walls of the longitudinal stiffening plates 7 are welded with transverse strips 6. Multiple groups of transverse stiffening plates 11 arranged along the transverse length of the ramp are welded between the bottom panel 4 and the tread panel 3. The transverse stiffening plates 11 are broken when they encounter the longitudinal stiffening plates 7, and the transverse stiffening plates 11 that are broken in the same direction must be ensured to be in the same straight line to ensure uniform force. The transverse stiffening plates 11 are mainly used to enhance the rigidity and stability of the ramp. The tread panel 3 is laid on the top surface of the ramp and erected on the longitudinal stiffening plates 7 and the transverse stiffening plates 11. A first box body 2 is fixedly connected between the end faces of the bottom panel 4 and the tread panel 3. The first box body 2 is assembled by four first flange plates 201 on the upper, lower, left and right sides, and an inner partition plate 202 is welded between the upper and lower first flange plates 201. A small guardrail 1 used as a skirting board is welded on the top of the first box body 2 to prevent objects from falling and causing unnecessary damage.

[0029] The longitudinal stiffener 7 and the upper strip 5 are welded by intermittent welding to reduce the welding deformation of the components.

[0030] The cross section of the ramp is trapezoidal, and the side with a larger contact area is welded to the embedded part on the column 12 .

[0031] All the parts described above are steel structures.

[0032] During installation, the user first installs and fixes the column 12 through the equipment, and the column 12 is provided with embedded parts before the processing is completed, so that the spiral ramp can be installed through the embedded parts on the column 12: The first step is to cut, connect, process the appearance and bend and deform the steel plate raw materials in advance; the butt welds need to be polished smooth before bending and assembling the parts.

[0033] In the second step, the first box body 2 is installed. First, the three first flange plates 201 are placed in a U shape and welded (as shown in FIG. Figure 4The inner partition 202 is assembled and welded, and then the upper first flange plate 201 of the first box body 2 is assembled and welded, and finally the small guardrail 1 is welded to the first box body 2. The small guardrail 1 is used as a skirting board to prevent objects from falling and causing unnecessary injuries.

[0034] The third step is to install the second box body 10. First, place the three second flange plates 101 in a U shape and weld them. After welding the first stiffening plate 103 between the two relatively welded second flange plates 101, add and weld partitions 102 at intervals. Assemble and weld them on the main body of the second box body 10 to complete the installation.

[0035] The fourth step is to install the guardrail top side cover plate 104, the inner stiffening plate 105 and the guardrail inner web 106. First, weld the guardrail top side cover plate 104 to the upper side of the side wall of the large guardrail 9, and weld the inner stiffening plate 105 set at intervals on the upper side of the outer surface of the large guardrail 9. Then, weld the guardrail inner web 106 between the guardrail top side cover plate 104 and the top of the second box body 10 to cover the inner stiffening plate 105, and a plug welding groove 107 is opened on the guardrail inner web 106. The plug welding groove 107 is used to grind the welding area of ​​the plug welding groove 107 after welding is completed, and the welds on both sides of the guardrail top side cover plate 104 need to be polished.

[0036] The fifth step is to install the tread panel 3, the bottom panel 4, the longitudinal stiffener 7 and the transverse stiffener 11, weld the lower strip 8 to the top of the bottom panel 4, weld the upper strip 5 to the bottom of the tread panel 3, weld the longitudinal stiffener 7 between the tread panel 3 and the bottom panel 4, and weld the side wall of the longitudinal stiffener 7 with a transverse strip 6, and weld the transverse stiffener 11 between the tread panel 3 and the bottom panel 4 along the length direction of the spiral direction, and weld the upper side of the longitudinal stiffener 7 with a symmetrically distributed pad 13, which is T-shaped with the longitudinal stiffener 7. Open structure. When assembling here, pay attention to ensuring the position accuracy of the upper strip 5 and the horizontality of the pad 13 to ensure that the subsequent tread panel 3 is overlapped with the pad 13 of the T-shaped disconnected structure without a gap during assembly and welding. Then weld the tread panel 3 and the bottom panel 4 to the second box body 10 respectively, and weld the first box body 2 to the ends of the tread panel 3 and the bottom panel 4. Then, the user uses the lifting equipment to assist in welding the welded steel structure to the embedded parts on the column 12 to complete the installation work, thereby completing the installation of the spiral ramp.

[0037] The lower strip 8 is arranged throughout the entire length and is disconnected at the transverse stiffener 11. In order to strengthen the left-right connection between the lower parts of the transverse stiffener 11 and enhance stability, the disconnection between the two is welded to form a cross-shaped structure to increase stability.

[0038] The upper strip 5 is arranged throughout the entire length and is disconnected at the transverse stiffener 11. In order to strengthen the left-right connection between the upper parts of the transverse stiffener 11 and enhance stability, the disconnection between the two is welded to form a cross-shaped structure to increase stability.

[0039] The longitudinal stiffeners 7 are arranged throughout the entire length and intersect with the transverse stiffeners 11 to enhance the stability of the ramp. The transverse strips 6 are arranged throughout the entire length to prevent instability due to the increased upper and lower spans.

[0040] Because the cross section of the spiral ramp is trapezoidal, and the side with a larger contact area is welded to the embedded parts on the column 12, the center of gravity of the spiral ramp can be located close to the column 12, making the spiral ramp more stable and increasing its load capacity.

[0041] The method of gradually installing by welding and assembling steel structural parts is simpler than the traditional concrete pouring method. It does not require on-site formwork and pouring, which facilitates rapid construction and reduces construction period. Compared with the concrete pouring method, the steel structure method has lower requirements on the foundation bearing capacity and smaller dead weight. Compared with the cast steel structure method, it is easy to adjust the shape and modify, and it can reduce the generation of construction waste during subsequent renovation or demolition.

[0042] When a spiral ramp at some stages is damaged, the user can cut the damaged section of the spiral ramp by cutting, and make a spiral ramp at the corresponding stage for welding, so as to facilitate the repair of the damaged spiral ramp.

[0043] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
