Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, specifically, it relates to a steel reinforcement structure and a rapid fabrication method thereof. Background Technology

[0002] In existing technology, longitudinal and transverse reinforcing bars need to be installed to form a reinforcing mesh before the floor slab is poured. Typically, the reinforcing bars are laid first, and then the intersections of the longitudinal and transverse reinforcing bars are connected to secure them. Common methods for connecting transverse and longitudinal reinforcing bars include lap splicing and welding.

[0003] Pre-laying rebar requires considerable time and effort to ensure accurate positioning of the horizontal and vertical reinforcing bars, followed by tying or welding, or sometimes laying the rebar while simultaneously tying or welding. Regardless of the method used, the entire process is extremely physically demanding, and inaccurate positioning during pre-laying can lead to significant problems in subsequent connections, resulting in floor slab quality issues. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the first objective of the present invention is to provide a steel reinforcement structure. This steel reinforcement structure is ingeniously designed, requires no welding, and only requires pushing the longitudinal steel bars to achieve rapid installation and positioning of the transverse and longitudinal steel bars during installation, which greatly reduces the manpower and time costs during installation. The accurate and fast positioning facilitates the precise installation of subsequent steel materials and can greatly improve production efficiency.

[0005] In view of the above-mentioned shortcomings in the prior art, the second objective of the present invention is to provide a rapid manufacturing method for steel reinforcement structures; this manufacturing method is easy to streamline and mass-produce.

[0006] To achieve the above objectives, the solution adopted by the present invention is as follows:

[0007] A reinforced concrete structure includes: transverse reinforcing bars, multiple sets of limiting mechanisms, multiple sets of sliding components, and multiple longitudinal reinforcing bars slidably connected to the transverse reinforcing bars along their length direction; the transverse reinforcing bars have sliding grooves; the sliding grooves extend along the length direction of the transverse reinforcing bars; the multiple sets of limiting mechanisms are spaced apart in the sliding grooves along the length direction of the transverse reinforcing bars; each sliding component includes a slider disposed within the sliding groove and a limiting block disposed outside the transverse reinforcing bar; both ends of the slider are connected to the longitudinal reinforcing bars and the limiting block, respectively; each limiting mechanism includes two sets of limiting components symmetrically arranged along the axis of the transverse reinforcing bars; each limiting component includes a guide component disposed within the sliding groove and a locking component disposed outside the transverse reinforcing bars; the guide component includes components sequentially connected to the longitudinal reinforcing bars in the sliding groove. The groove wall is fixedly connected to a limiting baffle and a hinged rod, and a guide baffle is hinged to the hinged rod; the axis of the hinged rod is perpendicular to the axis of the transverse reinforcement; the rotation direction of the guide baffle and the axis of the transverse reinforcement form an acute angle; two sets of guide components arranged opposite to each other form an active space for the slider to pass through; a locking component is connected to one end of the hinged rod; the locking component includes a movable rod, a connecting rod, and an elastic limiting member disposed on the connecting rod; the movable rod is disposed between the transverse reinforcement and the limiting block; one end of the movable rod is connected to the hinged rod, and the other end is connected to the connecting rod; the axis of the connecting rod is parallel to the axis of the hinged rod; the limiting block is recessed with two symmetrically arranged limiting grooves; the elastic limiting member can abut against the limiting grooves.

[0008] Furthermore, in a preferred embodiment of the present invention, one end of the limiting baffle is connected to the groove wall, and the other end extends toward another groove wall; the extending direction of the limiting baffle is perpendicular to the axis of the transverse reinforcing bar.

[0009] Furthermore, in a preferred embodiment of the present invention, the centerline of the longitudinal reinforcement is perpendicular to the centerline of the transverse reinforcement.

[0010] Furthermore, in a preferred embodiment of the present invention, the cross-section of the limiting block parallel to the axis of the transverse reinforcing bar is circular.

[0011] Furthermore, in a preferred embodiment of the present invention, the guide baffle is an elastic baffle.

[0012] Furthermore, in a preferred embodiment of the present invention, one end of the guide baffle is hinged to the hinge rod, and the other end extends toward another groove wall; the length of the two guide baffles arranged opposite each other is less than the width of the sliding groove.

[0013] Furthermore, in a preferred embodiment of the present invention, the elastic limiting member includes a buffer block and a spring; one end of the spring is connected to the connecting rod, and the other end is connected to the buffer block; the extension and retraction direction of the spring is parallel to the axis of the movable rod.

[0014] Furthermore, in a preferred embodiment of the present invention, a first magnetic sheet is provided on the side of the guide baffle away from the limiting baffle; a second magnetic sheet is provided on the slider; the first magnetic sheet and the second magnetic sheet can be magnetically connected.

[0015] Furthermore, in a preferred embodiment of the present invention, the angle between the axis of the movable rod and the extending direction of the guide baffle is greater than 90°.

[0016] The present invention also provides a rapid manufacturing method for the above-mentioned steel reinforcement structure, comprising: pushing the longitudinal steel bar along the length direction of the transverse steel bar to the movable space between the guide components at a designated position, at which point the two guide baffles are pushed open and the two movable rods move away from each other; then pushing the longitudinal steel bar in the opposite direction, the two guide baffles close under the pushing force of the longitudinal steel bar, the two movable rods move closer to each other, and the limiting baffle limits the guide baffles so that they cannot continue to rotate. The guide baffles provide initial positioning for the longitudinal steel bar. When the longitudinal steel bar slides in the opposite direction to approach the limiting baffles, the limiting elastic element is engaged in the limiting groove after abutting against the limiting block.

[0017] The beneficial effects of the steel reinforcement structure and its rapid fabrication method provided by this invention are:

[0018] (1) The steel reinforcement structure provided by this invention includes: transverse steel bars, multiple sets of limiting mechanisms, multiple sets of sliding components, and multiple longitudinal steel bars that are slidably connected to the transverse steel bars along the length direction of the transverse steel bars. Based on the ingenious design of the above-mentioned limiting mechanism and sliding component structure, and the design of the connection method between the limiting mechanism and sliding component structure and the transverse steel bars and the multiple longitudinal steel bars, the resulting steel reinforcement structure can simultaneously play the role of positioning and locking. It can fix the transverse steel bars first during the pre-laying of floor slab steel bars, and play the role of preliminary positioning of multiple longitudinal steel bars. The positioning is accurate and fast, which can facilitate the precise installation of subsequent steel bars and greatly improve production efficiency.

[0019] (2) The longitudinal reinforcement structure provided by the present invention has a very simple positioning operation. It is only necessary to push the longitudinal reinforcement in the forward and reverse directions along the length of the transverse reinforcement to achieve rapid installation and positioning of the transverse and longitudinal reinforcement.

[0020] (3) The steel reinforcement structure provided by the present invention has high operational safety, which can greatly reduce the probability of safety accidents and greatly reduce the manpower and time costs during installation.

[0021] (4) The steel reinforcement structure provided by the present invention can adjust the number of prefabricated longitudinal steel bars and the spacing of the limiting mechanism according to the actual floor slab conditions, and is suitable for the installation of steel reinforcement in various floor slabs.

[0035] Example 1

[0036] The following is in conjunction with the appendix Figure 1-8 This embodiment will be further described as follows:

[0037] This embodiment provides a reinforced steel structure 10. Please refer to [link / reference]. Figure 1-8 The reinforcing steel structure 10 includes: transverse reinforcing bars 100, multiple sets of limiting mechanisms 200, multiple sets of sliding components 300, and multiple longitudinal reinforcing bars 400 that are slidably connected to the transverse reinforcing bars 100 along their length. In this embodiment, the centerline of the longitudinal reinforcing bars 400 is perpendicular to the centerline of the transverse reinforcing bars 100.

[0038] In this embodiment, the transverse reinforcing bar 100 has a sliding groove 110 extending along the length of the transverse reinforcing bar 100. The sliding assembly 300 includes a slider 310 disposed within the sliding groove 110 and a limiting block 320 disposed outside the transverse reinforcing bar 100. The two ends of the slider 310 are respectively connected to the longitudinal reinforcing bar 400 and the limiting block 320. In this embodiment, the limiting block 320 has a circular cross-section parallel to the axis of the transverse reinforcing bar 100.

[0039] In this embodiment, multiple sets of limiting mechanisms 200 are spaced apart in the sliding groove 110 along the length of the transverse reinforcing bar 100. Specifically, the limiting mechanism 200 includes two sets of limiting components 210 symmetrically arranged along the axis of the transverse reinforcing bar 100. The limiting component 210 includes a guide component 220 disposed in the sliding groove 110 and a locking component 230 disposed outside the transverse reinforcing bar 100.

[0040] The guide assembly 220 includes a limiting baffle 221 and a hinge rod 222 that are fixedly connected to the wall of the sliding groove 110 in sequence, and a guide baffle 223 that is hinged to the hinge rod 222.

[0041] In this embodiment, a movable space 224 for the passage of the slider 310 is formed between two sets of guide components 220 arranged opposite to each other. Specifically, the axis of the hinge rod 222 is perpendicular to the axis of the transverse reinforcing bar 100. In this embodiment, the guide baffle 223 is an elastic baffle. The angle between the rotation direction of the guide baffle 223 and the axis of the transverse reinforcing bar 100 is acute. One end of the guide baffle 223 is hinged to the hinge rod 222, and the other end extends toward the other groove wall. The combined length of the two guide baffles 223 arranged opposite to each other is less than the width of the sliding groove 110.

[0042] In this embodiment, one end of the limiting baffle 221 is connected to the groove wall, and the other end extends toward another groove wall. The extension direction of the limiting baffle 221 is perpendicular to the axis of the transverse reinforcing bar 100.

[0043] In this embodiment, the locking assembly 230 includes a movable rod 231, a connecting rod 232, and an elastic limiting member 233 disposed on the connecting rod 232. The movable rod 231 is positioned between the transverse reinforcing bar 100 and the limiting block 320. One end of the movable rod 231 is connected to the hinge rod 222, and the other end is connected to the connecting rod 232. The angle between the axis of the movable rod 231 and the extension direction of the guide baffle is greater than 90°. The axis of the connecting rod 232 is parallel to the axis of the hinge rod 222. The limiting block 320 has two symmetrically arranged limiting grooves 321 recessed in it, and the elastic limiting member 233 can abut against the limiting grooves 321. In this embodiment, the elastic limiting member 233 includes a buffer block 234 and a spring 235. One end of the spring 235 is connected to the connecting rod 232, and the other end is connected to the buffer block 234. The extension direction of the spring 235 is parallel to the axis of the movable rod 231.

[0044] This embodiment also provides a rapid manufacturing method for the above-mentioned steel reinforcement structure 10, including: pushing the longitudinal steel reinforcement 400 along the length direction of the transverse steel reinforcement 100 to the movable space 224 between the guide components 220 at a designated position, at which time the two guide baffles 223 are pushed open and the two movable rods 231 move away from each other; then pushing the longitudinal steel reinforcement 400 in the opposite direction, the two guide baffles 223 close under the pushing force of the longitudinal steel reinforcement 400, the two movable rods 231 approach each other, and the limiting baffle 221 limits the guide baffle 223 so that it cannot continue to rotate. The guide baffle 223 provides initial positioning for the longitudinal steel reinforcement 400. When the longitudinal steel reinforcement 400 slides in the opposite direction to approach the limiting baffle 221, the limiting elastic element is engaged in the limiting groove 321 after abutting against the limiting block 320, thereby providing further positioning for the longitudinal steel reinforcement 400.

[0045] In summary, this embodiment provides a reinforcing steel structure 10 and its rapid fabrication method. This reinforcing steel structure 10 is ingeniously designed, requiring no welding. During installation, simply pushing the longitudinal reinforcing steel 400 achieves rapid installation and positioning of the transverse and longitudinal reinforcing steel 100, significantly reducing labor and time costs during installation. Accurate and rapid positioning facilitates precise subsequent installation of steel materials, greatly improving production efficiency. This fabrication method is easily streamlined and mass-produced.
