Description

Technical Field

[0001] The invention relates to the technical field related to construction engineering technology, and in particular to an assembled finished steel cage for a structural column. Background Art

[0002] Steel cage plays a vital role in construction projects. It not only enhances the strength and stability of concrete, but also plays a significant role in improving the seismic performance and durability of the entire structure. At present, the traditional frame structure construction process in the field of housing construction is: measurement and setting out, frame erection, column reinforcement binding, formwork laying, beam and slab reinforcement binding, formwork sealing, and concrete pouring. The structure of the steel cage is usually composed of longitudinally arranged main bars and transversely arranged stirrups, forming a solid cage structure, in which the main bars are usually longitudinally placed steel bars that bear the main tensile force, while the stirrups are transversely placed steel bars that are used to constrain the main bars and increase the stability and shear resistance of the structure. The stirrups and main bars are mostly connected by wire binding or by spot welding. This design enables the steel cage to provide the necessary support and elasticity when bearing heavy loads, such as bridges, high-rise buildings, tunnels and other important building structures. In specific applications, steel cages are not only used to reinforce foundation piles or columns, but are also widely used in the construction of beams and slabs of buildings, ensuring the integrity and stability of concrete structures when subjected to huge pressure and impact. Through the careful configuration and connection of the main reinforcement and stirrups, the steel cage can effectively disperse the load pressure and reduce the risk of damage caused by load concentration.

DETAILED DESCRIPTION

[0035] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-9 This embodiment provides a structural column assembled finished steel cage, the steel cage includes main bars 1, stirrups 2 and fixed bars 3. The main bars 1 and the fixed bars 3 are evenly arranged in a rectangular array, such as Figure 2 As shown, the main bars 1 are set to twelve, the fixed bars 3 are set to four, and the four fixed bars 3 are arranged inside the twelve main bars 1. The stirrups 2 located on the same horizontal plane are set to a group of bindings, such as Figure 1 and Figure 3 As shown, multiple groups of binding parts are arranged in parallel. The stirrups 2 surround the outer wall of the main reinforcement 1 and the fixed reinforcement 3. During installation, the stirrups 2 are first tied with steel wires at the fitting parts of the main reinforcement 1 and the fixed reinforcement 3 to make the stirrups 2, the main reinforcement 1 and the fixed reinforcement 3 preliminarily connected and positioned. Then, the stirrups 2 and the main reinforcement 1 and the stirrups 2 and the fixed reinforcement 3 are further connected by spot welding to increase the overall stability of the steel cage and complete the steel cage.

[0038] Compared with the existing on-site installation of steel cages, after the finished steel cages are tied off-site, they are uniformly hoisted by tower cranes, reducing the workload of steel workers climbing up. At the same time, the steel tying is placed off-site to avoid most of the cross-operation workload. Only individual workers are required to cooperate with the hoisting on site to achieve the effect of assembly, reduce the number of on-site construction personnel, and thus reduce the safety hazards of cross-construction. At the same time, the finished steel cages can be made in advance and are not affected by on-site construction, which can effectively speed up the construction progress.

[0039] However, in order to adapt to more buildings and meet the height or depth of the buildings, multiple steel cages need to be connected up and down to increase the overall length of the steel cages. Therefore, the main reinforcement 1 and the fixed reinforcement 3 after the increase in length are composed of multiple steel bars connected up and down. Figure 3 and Figure 4 As shown, two adjacent steel bars are connected by a connecting tube 4, wherein the connecting tube 4 includes an inner sleeve 41 and an outer sleeve 42. Figure 4 As shown, before installation, thread grooves are machined on both ends of the outer wall of the steel bar, and a threaded hole is opened inside the inner sleeve 41, and then an inner sleeve 41 is threadedly sleeved on the upper end of the lower steel bar, and the outer sleeve 42 is threadedly sleeved on the outer wall of the inner sleeve 41, and rotated to the bottom of the outer wall of the inner sleeve 41 to expose the upper end of the inner sleeve 41, and then the other inner sleeve 41 is threadedly sleeved on the lower end of the upper steel bar, and one end of the inner sleeve 41 of the upper and lower steel bars is fitted, and then the outer sleeve 42 is rotated to move the outer sleeve 42 upward, and the outer sleeve 42 moving upward is randomly threadedly sleeved on the outer wall of the upper inner sleeve 41, and the outer sleeve 42 is threadedly connected to the two inner sleeves 41, so that the two steel bars can be connected.

[0040] During the transportation and installation of the steel cage, vibrations will occur, which can easily cause the outer sleeve 42 to rotate downward through the threads and its own gravity, and then separate from the inner sleeve 41 at the upper end. In order to ensure the connection between the upper and lower steel bars, the outer wall of the connecting tube 4 is engaged with the limit shell 43. Figure 5 As shown, two limit shells 43 are provided, and the two limit shells 43 can be combined into a cylindrical structure. Figure 6 and Fig. 9 As shown, the end surfaces of the two limiting shells 43 are provided with grooves, which can be engaged with the outer wall of the steel bar and the connecting tube 4, thereby limiting the connected outer sleeve 42 and preventing the outer sleeve 42 from maintaining connection with the two inner sleeves 41.

[0041] like Figure 7 and Figure 8 As shown, the two limiting shells 43 are both installed with a connecting mechanism 5, which includes a hook 51, a limiting block 52 and a block 53, and the block 53 is fixedly connected below the end surface of one of the limiting shells 43. Figure 6As shown, the end surface of the other limiting shell 43 is fixedly connected with a clamping frame 531, and the clamping block 53 can be inserted into the frame hole of the clamping frame 531, thereby connecting the lower ends of the two limiting shells 43. The clamping hook 51 is fixedly connected to the upper end surface of the limiting shell 43, as shown in FIG. Figure 8 As shown, the limiting shell 43 is provided with a slot, and the cross-section of the slot is set to be L-shaped, that is, the notches at both ends of the slot are respectively located at the upper end of the limiting shell 43 and the end surface of the limiting shell 43. After the two limiting shells 43 are combined and spliced, the hook 51 of the limiting shell 43 can be inserted into the slot of the limiting shell 43.

[0042] like Figure 8 As shown, the limit block 52 is slidably installed in the card slot, and a first elastic member 521 is also installed inside the card slot. The upper end of the first elastic member 521 is fixedly connected to the lower end of the limit block 52. The first elastic member 521 is set as a spring, and the limit block 52 can be applied with an upward elastic force through the first elastic member 521. After the hook 51 is inserted into the card slot of the limit shell 43, the hook 51 is hooked with the limit block 52, thereby preventing the hook 51 from being separated from the card slot. When it is necessary to cancel the connection between the two limit shells 43, the limit block 52 can be pressed downward through the card slot notch at the upper end of the limit shell 43, so that the limit block 52 can be disconnected from the hook 51, so that the hook 51 can be pulled out from the notch of the card slot, and the connection between the two limit shells 43 is cancelled.

[0043] Embodiment 2

[0044] See also Figure 10-15 , further improvements are made on the basis of the first embodiment:

[0045] In actual construction, the upper end of the steel cage needs to be connected to the beam steel bar. The connection between the steel cage and the beam steel bar is an important step in building the structural frame, which is mainly used to ensure the structural safety and stability of the building. Therefore, the upper end of the main reinforcement 1 is fixedly connected with a plurality of transverse reinforcements 11. The transverse reinforcements 11 are vertically distributed with the main reinforcements 1. For example, the main reinforcements 1 are set to twelve and the fixed reinforcements 3 are set to four. The transverse reinforcements 11 on the same horizontal plane are set to four, and the four transverse reinforcements 11 on the same horizontal plane are set to a group of beam reinforcements. Different groups of beam reinforcements are set according to the design height of the beam itself. In theory, the more groups of beam reinforcements there are, the greater the height of the beam itself.

[0046] At present, the connection between the main reinforcement 1 of the structural column of the building and the transverse reinforcement 11 of the beam is mostly connected by binding, which has high labor intensity, low efficiency, and insufficient consistency and reliability. During construction, the transverse reinforcement 11 is generally inserted into the inside of the main reinforcement 1 and arranged vertically with the main reinforcement 1, and the transverse reinforcement 11 and the main reinforcement 1 are crossed. However, in order to ensure the strength of the transverse reinforcement 11, the main reinforcement 1 and the transverse reinforcement 11 must be tied together. When the transverse reinforcement 11 and the main reinforcement 1 cross, the construction space is relatively small, and there is basically not enough space to bind the main reinforcement 1 and the transverse reinforcement 11. Therefore, in order to facilitate the connection of the transverse reinforcement 11 at the upper end of the main reinforcement 1, a limited position frame 6 and a fixing mechanism 7 are set at the upper end of the main reinforcement 1.

[0047] Among them, the number of limit frames 6 is the same as the number of groups of beam reinforcements. The limit frame 6 includes a fixed sleeve 61, a connecting rod 62 and a positioning block 63. The fixed sleeve 61 is set to sixteen. The specific number of the fixed sleeves 61 is determined according to the number of main reinforcements 1 of the beam during actual construction. They are slidably sleeved on the outer side walls of the main reinforcement 1 and the fixed reinforcement 3 respectively. The outer side wall of the fixed sleeve 61 is fixedly connected with an insertion rod. Both ends of the connecting rod 62 are provided with sleeve holes. Through the sleeve holes, the two ends of the connecting rod 62 are respectively sleeved on the outer side walls of the insertion rods of two adjacent fixed sleeves 61. The outer side wall of the insertion rod is provided with a sliding hole. The positioning block 63 is slidably inserted in the sliding hole. A second elastic member 631 is also installed in the sliding hole. The second elastic member 631 is set as a spring. The second elastic member 631 applies elastic force to the positioning block 63, so that one end of the positioning block 63 slides out from the opening of the sliding hole. A positioning hole is provided on the outer wall of the connecting rod 62, and the positioning hole and the sleeve hole are connected to each other. The sleeve hole of the connecting rod 62 is set to a truncated cone-shaped hole. Therefore, the cross-sectional side wall of the sleeve hole is an inclined surface. After the connecting rod 62 is sleeved on the outer wall of the insertion rod, the side wall of the sleeve hole applies pressure to one end of the positioning block 63, pressing the positioning block 63 into the sliding hole. After the sleeve hole of the connecting rod 62 is completely sleeved on the insertion rod of the fixed sleeve 61, the positioning block 63 is aligned with the positioning hole of the connecting rod 62. The positioning block 63, which is subjected to the elastic force of the second elastic member 631, will extend from the sliding hole and engage in the positioning hole of the connecting rod 62. At this time, the connection between the fixed sleeve 61 and the connecting rod 62 is completed. Of course, the connection between the fixed sleeve 61 and the connecting rod 62 is not limited to the positioning block 63, and the sliding hole of the insertion rod can also be emptied. After the connecting rod 62 is sleeved on the outer wall of the insertion rod, the positioning hole of the connecting rod 62 is aligned and connected with the sliding hole of the insertion rod. At this time, a pin can be used to insert into the sliding hole and the positioning hole to prevent the connecting rod 62 from separating from the fixed sleeve 61.

[0048] like Fig.14As shown, the outer wall of the fixing sleeve 61 is threadedly connected with a fixing screw 611. After the fixing sleeve 61 is sleeved on the outer wall of the main rib 1 or the fixing rib 3 and the position of the fixing sleeve 61 is determined, the fixing screw 611 is tightened so that one end of the fixing screw 611 extends into the fixing sleeve 61 and one end of the fixing screw 611 contacts the outer wall of the main rib 1 or the fixing rib 3. Taking the main rib 1 as an example, tightening the fixing screw 611 increases the friction coefficient between the fixing screw 611 and the main rib 1, and fixes the fixing sleeve 61 on the main rib 1 through damping.

[0049] like Fig.12 As shown, the limit frame 6 is set as a rectangular frame structure, and the connecting rod 62 can be replaced according to the spacing between the main reinforcement 1 and the fixed reinforcement 3. After the fixed sleeve 61 is fixed to the outer wall of the main reinforcement 1 and the fixed reinforcement 3 by the fixing screw 611, the limit frame 6 forms a similar effect to the stirrup 2. At this time, the limit frame 6 is used to maintain the stability of the position of the longitudinal main reinforcement 1 or the fixed reinforcement 3 during the concrete pouring process. The limit frame 6 prevents the upper end of the main reinforcement 1 or the fixed reinforcement 3 from moving during the concrete solidification process, ensuring that the main reinforcement 1 or the fixed reinforcement 3 is arranged accurately according to the design requirements, thereby ensuring the bearing capacity and performance of the overall structure of the column. In the concrete elements of the column, the limit frame 6 provides a lateral restraining force, which helps to improve the shear resistance of the structure and helps the concrete resist lateral pressure and distortion. This restraining effect enables the concrete to better maintain its shape when subjected to force and avoid cracking and breaking.

[0050] like Fig.11 and Fig.12 As shown, the fixing mechanism 7 includes a sliding rod 71, a sliding sleeve 72 and a pressing rod 73, wherein the sliding rod 71 is located above the two connecting rods 62 on both sides of the limiting frame 6, as shown in FIG. Fig.13 As shown, the two slide bars 71 and the connecting rod 62 are combined into a triangular structure. Fig.12 As shown, two symmetrical fixing mechanisms 7 located in the same horizontal plane are arranged as a group of fixing parts, two pressure rods 73 of the fixing mechanism 7 on one side are arranged, and four sliding sleeves 72 are arranged. Two sliding sleeves 72 are fixedly connected to the outer side wall of one pressure rod 73, and the sliding sleeves 72 on the two pressure rods 73 are symmetrically arranged, and the sliding sleeves 72 are slidably sleeved on the outer side wall of the sliding rod 71.

[0051] After the limit frame 6 is installed, Fig.10 and Fig.11 As shown, the transverse reinforcement 11 is slidably inserted between the angle between the main reinforcement 1 and the slide bar 71. Fig.11 and Fig.12As shown, by controlling the two pressure rods 73 to move away from each other, the sliding sleeve 72 is driven to slide downward on the outer wall of the sliding rod 71. After the pressure rod 73 contacts the transverse rib 11, the main rib 1, the sliding rod 71 and the pressure rod 73 are clamped on the outer wall of the transverse rib 11 in a triangular structure. In order to increase the friction coefficient of the main rib 1, the sliding rod 71 and the pressure rod 73 to the transverse rib 11, and then fix the transverse rib 11 through damping, the pressure rod 73 is connected to a control frame 74. Fig.15 As shown, an adjustment cylinder 741 is provided between the control frames 74 of the two pressure rods 73 in the fixing mechanism 7, that is, two symmetrical threaded holes are respectively provided at both ends of the adjustment cylinder 741, and the adjustment cylinder 741 is threadedly connected to the two control frames 74 through the threaded holes. When in use, the two control frames 74 can be driven to move synchronously (move away from each other or move closer to each other) by rotating the adjustment cylinder 741, and after the two control frames 74 move away from each other, the pressure rod 73 can be pressed on the upper end of the transverse rib 11. By tightening the adjustment cylinder 741, the pressure applied by the pressure rod 73 to the transverse rib 11 is increased, and then the transverse rib 11 is clamped and fixed by the main rib 1, the sliding rod 71 and the pressure rod 73, and the connection between the transverse rib 11 and the main rib 1 is completed.

[0052] Compared with mechanical connection, manual binding is relatively inefficient. Under tight engineering schedule requirements, manual binding requires a certain amount of technical content and may become a bottleneck in engineering schedule. The limit frame 6 and the fixing mechanism 7 are both prefabricated structures. During installation, only four simple operations are required: sleeve (sleeve the limit frame 6 on the main reinforcement 1 and the fixing reinforcement 3), rotate (tighten the fixing screw 611), insert (insert the transverse reinforcement 11 at the angle between the main reinforcement 1 and the slide bar 71), and turn (rotate the adjustment cylinder 741 to move the pressure rod 73 downward). The transverse reinforcement 11 can be fixed on the main reinforcement 1. Therefore, using the limit frame 6 and the fixing mechanism 7 to fix the transverse reinforcement 11 on the main reinforcement 1 can increase work efficiency, reduce work difficulty, and reduce the labor burden of workers. The quality of manual binding depends largely on the skills and experience of workers. There may be differences in the binding quality of different workers, which may lead to inconsistency in construction quality and increase the risk of the structure. Therefore, in the case of main reinforcement 1 , transverse reinforcement 11 and fixing mechanism 7 of the same specifications, the use of limit frames 6 and fixing mechanism 7 to fix the transverse reinforcement 11 on the main reinforcement 1 can also increase the consistency and reliability of the connection of the transverse reinforcement 11 .

[0053] When the end of the top main reinforcement 1 is located at the floor level, it is necessary to use the connecting tube 4 and the limiting shell 43 to connect the two main reinforcements 1 and the two fixed reinforcements 3, increase the length of the main reinforcement 1 and the fixed reinforcement 3, and realize the vertical connection between the adjacent main reinforcements 1 and the vertical connection between the adjacent fixed reinforcements 3. At this time, the transverse reinforcement 11 can be connected to the connection between the two adjacent main reinforcements 1. When the transverse reinforcement 11 is connected to the connection between the two adjacent main reinforcements 1, taking the main reinforcement 1 as an example, the limiting frame 6 of the lower main reinforcement 1 is first installed, and then fixed by the fixing screw 611, and then a main reinforcement 1 is connected to the upper part of the main reinforcement 1 through the connecting tube 4 and the connecting mechanism 5. At this time, it is necessary to replace the fixing sleeve 61 that matches the limiting shell 43. After the fixing sleeve 61 is sleeved on the outer wall of the limiting shell 43, the fixing sleeve 61 is also fixed by the fixing screw 611. When the fixing sleeve 61 enables the limiting shell 43 to be installed at the connection between the two main bars 1 , the fixing sleeve 61 can further increase the stability of the two spliced ​​limiting shells 43 and prevent the two limiting shells 43 from being separated.
