Description

  The present invention relates to a spiral ridge structure, and more specifically, to a composite spiral ridge structure formed by combining spiral ridge structures of different shapes and sizes.

In general reinforced concrete structures, in order to strengthen the seismic structure, the reinforcing bars and the concrete continue to be effectively combined even in the process of being subjected to vibrations, generally by connecting the reinforcing bars and the concrete using a stirrup. It is possible to strengthen the seismic structure.

Since Taiwan is geographically located where earthquakes occur frequently, the ability of building strength to tensile strength and shear strength is important. In the design of steel-framed reinforced concrete, most steel frames are the main components of load capacity, tensile strength, and shear strength. After that, by adding a reinforcing bar and a stirrup around the steel frame, the force received by the steel frame is shared to reinforce the concrete adsorption force, and the resonance when receiving the force from the side is suppressed. However, in the present steel reinforced concrete design, the design and application method of the steel part is simple, so it cannot easily meet the actual design and construction needs. In addition to this, there is still a limit to the strength that a single spiral scissors can provide under reasonable design, limited by the production and assembly techniques of the spiral scissors.

In view of the above problems, in order to improve and solve the above-mentioned drawbacks, the present invention performs a combination of repeated research and academic theory, and submits the present invention in which the design is rational and effective to improve the above-mentioned drawbacks. .

The main object of the present invention is to provide a composite spiral scissor structure that can be formed by combining spiral scissors structures of different sizes and shapes, thereby increasing the tightening force and enhancing the rigidity of the entire structure. And

Another object of the present invention is to provide a composite type composite spiral ridge structure used for a skeleton of a structure formed by grouting.

Another object of the present invention is to provide a composite spiral scissor structure that can increase construction efficiency by combining different spiral scissors structures to form a composite spiral scissor structure.

By forming a combination of different sizes and shapes of spiral ridge structures, the tightening force can be increased and the hardness of the entire structure can be enhanced, and the construction efficiency can be increased.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIG. 1, the first spiral scissors 200 and the second spiral scissors 300 are each a closed scissors, and the feature of this closed scissors is that the ends are closed on the spiral scissors. . However, the first spiral scissors 200 and the second spiral scissors 300 may be general spiral scissors. Among them, the first spiral rod 200 includes a joining side 210, and at this time, the axial centers of the first spiral rod 200 and the second spiral rod 300 are parallel, and the joining side 210 and the second spiral rod 300 are arranged in parallel. Intersections 290 can be formed by crossing (see FIG. 2).

As shown in FIG. 2b, the overlapping portion 290 formed by crossing the first spiral ridge 200 and the second spiral ridge 300 includes two end points, and the first end point 370 and the second end point 370, respectively. This is the second end point 390. Even if the first spiral rod 200 and the second spiral rod 300 are not different in the number of reinforcing bars or the material, there are always two end points when they intersect each other. As shown in FIG. 3, the first and second triangular gluteal muscles 400 and 500 are closed gluteal muscles, but they may be non-closed gluteal muscles or general gluteal muscles.

As shown in FIGS. 3a and 3b, the triangular structures of the first and second triangular barbs 400 and 500 include a first apex 410 and a second apex 510, respectively. The first apex portion 410 and the second apex portion 510 correspond to each other, and the axes of the first triangular reflexes 400 and the second triangular reflexes 500 are in parallel with each other. In FIG. 4a, which is a preferred embodiment of the present invention, the first apex 410 of the first triangular scissors 400 is located at the overlapping portion 290 along the linear direction connecting the first end point 370 and the second end point 390 of the overlapping portion 290. Plug in. As shown in FIG. 4b, since the position of the second triangular barbs 500 and the position of the first triangular barbs 400 are opposite to each other, the second apex 510 of the second triangular barbs 500 has an overlapping portion 290. By inserting into the overlapping portion 290 along the direction of the straight line connecting the second end point 390 and the first end point 370 and the direction opposite to the first triangular scissors 400, the composite spiral scissors structure 100 similar to an ellipse is formed. In addition, the reinforcing bar and the concrete can be effectively combined. Therefore, the tightening force can be increased and the entire structure can be strengthened. However, in other embodiments, the center of gravity of the cross section of the first triangular barbs 400 is on the first end point 370 and the center of gravity of the cross section of the second triangular barbs 500 is on the second end point 390. Further, both ends of the first triangular scissors 400 other than the first apex 410 are tangents of the circumferences of the first spiral scissors 200 and the second spiral scissors 300, respectively. At the same time, the second triangular scissors 500 form a compound spiral scissor structure 100 similar to the above-mentioned ellipse by cutting the circumferences of the first spiral scissors 200 and the second spiral scissors 300 cleanly. .

As shown in FIG. 5a, it further includes at least one axial reinforcing bar 600, which is installed at the intersection of the first spiral rod 200 and the second spiral rod 300 and used to define the overlapping portion 290. Among them, the installation direction of the axial rebar 600 can be adjusted flexibly in accordance with the construction code and different design demands, and the ends of the first spiral rod 200 and the second spiral rod 300 can be adjusted. The bending at the portion fixes the composite spiral saddle structure 100 in an insubstantial fixing manner. In addition, the composite spiral saddle structure 100 can be defined using a substantially fixing method (a method that can provide a similar effect such as welding, screwing, bundling, or a mixing method).

The first helical rod 200 and the second helical rod 300 of the composite helical rod structure 100 of the present invention are both circular helical rods and have the same cross-sectional area. Among them, the first spiral ridge 200 and the second spiral ridge 300 may each have a rectangular spiral fold, an elliptical spiral fold, a polygonal spiral fold, and other shapes that can provide similar effects. The cross-sectional area can be changed according to the design demand. In addition, the preferred first spiral ridge 200 and the second spiral ridge 300 are uniform and continuous spiral ridges. Among them, the first spiral ridge 200 and the second spiral ridge 300 may each be a spiral ridge that is not uniform in each stage, such as having a narrow top and a narrow bottom, corresponding to the design demand. Further, the first triangular reflexes 400 and the second triangular reflexes 500 are both triangular helical reflexes. In order to match the width of the gap between the first spiral scissors 200 and the second spiral scissors 300, the first triangular scissors 400 and the second triangular scissors 500 are respectively adjusted to meet the design demand. Spiral rods that are not uniform such as narrow and wide below may be used. Further, the axial reinforcing bar 600 is installed at both ends of the portion where the first triangular scissors 400 overlap with the first spiral scissors 200 and the second spiral scissors 300, respectively. The mutual distance between the spiral ridge 200 and the second spiral ridge 300 can be determined.

As shown in FIG. 5 b, the mutual distance between the second triangular scissors 500 of the present invention, the first spiral scissors 200 and the second spiral scissors 300 can also be determined by the axial reinforcing bars 600. At this time, the axial reinforcing bar 600 is installed at a location where the second triangular reinforcing bar 500 overlaps with the first helical rod 200 and the second helical rod 300, respectively. Also, as shown in FIGS. 1 and 3a, the first spiral rod 200 includes a first gap first gap 250, and the second spiral rod 300 includes a second gap 350, and the first triangle The heel bar 400 includes a third gap 450, and the second triangular barb 500 includes a fourth gap 550. The preferred ratio of the four is between 1: 1: 1: 1 to 1: 10: 20: 100. This ratio appropriately strengthens the effective bond between the reinforcing bar and the concrete, and further increases the clamping force of the concrete and strengthens the entire structure.
