Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular, to a steel reinforced concrete wall slab of a super high-rise core tube structure. Background Art

[0002] The steel reinforced concrete wall slab of the super high-rise core tube structure is one of the core components of the core tube system. Its essence is the innovative application of the steel reinforced concrete composite structure in super high-rise buildings. The core tube is located in the center of the building and is enclosed by auxiliary spaces such as elevator shafts, stairwells, and equipment pipe shafts. It is the "vertical skeleton" of super high-rise buildings.

[0003] The structure of the steel reinforced concrete wall slab includes a steel skeleton and an outer wrapped concrete. The steel skeleton is the internally placed H-shaped steel, cruciform steel section, or steel plate wall, which serves as the main load-bearing member. The outer wrapped concrete is high-strength concrete that wraps the steel to form an integral load-bearing system. It also includes a two-way steel mesh to enhance the shear and tensile resistance. The steel and concrete work together, and the lateral stiffness is increased by 30%-50% compared with ordinary reinforced concrete shear walls, effectively resisting wind loads and seismic actions. The addition of steel delays the cracking of concrete, the hysteretic curve is plump, and the energy dissipation capacity under earthquakes is increased by more than 40%. It also has stronger fire resistance and corrosion resistance, extending the service life of the structure. Welding studs and steel bar couplers are usually welded on the steel plate wall. The studs are used to enhance the bonding force between the steel plate wall and the concrete, and the steel bar couplers are used to connect with steel bars, so that adjacent steel plate walls are connected by steel bars, enhancing the stability between the steel plate walls.

[0004] Currently, in the prior art, concrete is usually poured on the steel plate wall to form a steel reinforced concrete wall slab. The couplers on the steel plate wall are generally circular sleeves with internal threads, and the two ends of the steel bars are also provided with matching threads, so that the two ends of the steel bars are respectively threadedly connected to the couplers on two adjacent steel plate walls. However, there is an angular error within a reasonable range during the installation of the steel plate wall, making the two steel plate walls not completely parallel. As a result, when connecting the steel bars, the steel bars are inclined and it is difficult to accurately dock with the coupler at the other end, and the coupler needs to be cut off and re-welded, which easily affects the construction efficiency. Therefore, it does not meet the existing requirements, and for this reason, we propose a steel reinforced concrete wall slab of a super high-rise core tube structure. Summary of the Invention

[0005] The present invention provides a super-high-rise core tube structure steel-concrete slab wall. The super-high-rise core tube structure steel-concrete slab wall can allow the steel bars and connectors to still be connected within a reasonable error range, thereby improving construction efficiency. It solves the problem mentioned in the above background technology that the steel plate wall has an angular error within a reasonable range during installation, which makes the two steel plate walls not completely parallel, resulting in the steel bars being tilted when connecting them, making it difficult to accurately connect with the connector at the other end.

[0040] According to some embodiments of the present disclosure, a steel reinforced concrete slab wall for a super high-rise core tube structure is provided. Refer to Figure 1 — Figure 16As shown in the figure, the super high-rise core tube structure steel concrete slab wall includes a steel plate wall 100, welding nails 110 welded to the outside of the steel plate wall 100, steel bars 120 arranged between the two steel plate walls 100, and a concrete shell 130 cast on the outside of the steel plate wall 100. A connector 140 is fixedly installed on the outside of the steel plate wall 100 by welding. The connector 140 is configured to be in a trumpet shape. A clamping assembly 150 for fixing the steel bar 120 is slidingly provided on the side wall of the connector 140. A driving assembly 160 for driving the clamping assembly 150 is provided on the side of the steel plate wall 100. The driving assembly 160 includes a first steel wire 161 arranged on the side of the clamping assembly 150. A clamping strip 170 is rotatably provided on the inside of the connector 140. The clamping strip 170 is used to engage with the thread at the end of the steel bar 120.

[0041] In this way, the bell-mouth design of the connector 140 improves the tolerance for the inclination of the steel bar 120, so that the steel bar 120 can be docked with the connector 140 within a reasonable inclination range, and then the driving component 160 drives the clamping component 150 to gather inward to clamp and fix the steel bar 120, thereby ensuring the stability of the connection between the steel bar 120 and the connector 140. The clamping strip 170 is also engaged with the threaded groove at the end of the steel bar 120 to further improve the firmness of the connection of the steel bar 120, and avoids the problem in the prior art that the cylindrical sleeve often needs to be cut and re-welded as much as possible, thereby effectively improving the efficiency of steel concrete slab wall construction.

[0042] In addition, the number of welding nails 110 is set to be several, and several welding nails 110 are evenly arranged on the outside of the steel plate wall 100. The number of connectors 140 is the same as the number of steel bars 120. The steel bars 120 are inserted into the connectors 140. The concrete shell 130 is wrapped around the steel plate wall 100, the welding nails 110 and the outside of the connector 140 to form a steel concrete slab wall. Through the setting of numerous welding nails 110, the contact area between the steel plate wall 100 and the concrete shell 130 is increased, so that the combination of the concrete shell 130 and the steel plate wall 100 is more firmly established, thereby improving the strength of the steel concrete slab wall.

[0043] In some embodiments, in the embodiment where the clamping assembly 150 is provided on the side of the connector 140, Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown in the figure, the clamping assembly 150 includes a slide bar 151 slidably inserted into the side wall of the adapter 140, a universal ball 152 fixedly installed at the end of the slide bar 151, and a clamping plate 153 rotatably sleeved outside the universal ball 152. A set of clamping assemblies 150 is provided on the side of one adapter 140, and the number of a set of clamping assemblies 150 is set to four. The clamping plate 153 is located inside the adapter 140, and the clamping plate 153 is an arc-shaped plate configured to cooperate with the steel bar 120; the clamping assembly 150 further includes a cavity 154 opened inside the slide bar 151, a piston 155 cooperating with the cavity 154, a connecting rod 156 slidably inserted into the end of the slide bar 151 and fixedly connected to the piston 155, a sealing film 157 fixedly arranged in the cavity 154, a through hole 158 jointly opened inside the slide bar 151 and the universal ball 152 and communicating with the cavity 154, and a solidifying agent filled between the piston 155 and the sealing film 157. The sealing film 157 is a plastic film, the clamping assembly 150 is a steel part, and the solidifying agent is a steel-bonding adhesive.

[0044] In some embodiments, in the implementation manner where the driving assembly 160 is provided on the side of the steel plate wall 100, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 11 、 Figure 12 and Figure 13 As shown in the figure, the driving assembly 160 further includes a ring 162 fixedly installed at the end of the connecting rod 156, and a rotating nail 163 rotatably arranged on the side of the steel plate wall 100. A plurality of adapters 140 are horizontally and evenly arranged outside the steel plate wall 100. The first steel wire 161 sequentially passes through the rings 162 on each set of clamping assemblies 150. One end of the first steel wire 161 is fixedly connected to one of the welding nails 110, and the other end of the first steel wire 161 is fixedly connected to the rotating nail 163.

[0045] Further, a rotating cylinder 164 is fixedly sleeved outside the rotating nail 163. A fixed cylinder 165 is rotatably sleeved outside the rotating cylinder 164. The fixed cylinder 165 is fixedly connected to the steel plate wall 100. A ratchet 166 is rotatably installed inside the fixed cylinder 165. The number of ratchets 166 is set to several, and several ratchets 166 are circumferentially and evenly arranged inside the fixed cylinder 165. A first torsion spring 167 is coaxially installed on the side of each ratchet 166. One end of the first torsion spring 167 is fixedly connected to the inner wall of the fixed cylinder 165, and the other end of the first torsion spring 167 is fixedly connected to the ratchet 166. A ratchet slot 168 for cooperating with the ratchet 166 is formed on the side of the rotating cylinder 164. The number of ratchet slots 168 is the same as the number of ratchets 166. A slot 169 is formed at the end of the rotating nail 163. The slot 169 is used to insert the output shaft of the motor or the drill bit of the impact drill, facilitating the rapid rotation of the rotating nail 163, so that the first steel wire 161 can be quickly wound around the rotating nail 163.

[0046] Specifically, the number of clamping strips 170 is set to several. An activity groove 171 is formed in the inner wall of the connector 140. The number of activity grooves 171 is the same as the number of clamping strips 170. Several clamping strips 170 are respectively rotatably arranged in the corresponding activity grooves 171. A rotating shaft is rotatably inserted into the side of each clamping strip 170. The end of the rotating shaft is fixedly connected to the activity groove 171. A second torsion spring 172 is sleeved outside each rotating shaft. One end of the second torsion spring 172 is fixedly connected to the inner wall of the connector 140, and the other end of the second torsion spring 172 is fixedly connected to the clamping strip 170.

[0047] Through the above technical solution, when the super high-rise core tube structure steel concrete slab wall provided by the present invention is used, one end of the steel bar 120 is first threadedly connected to the commonly used cylindrical sleeve on a steel plate wall 100, and then the other end of the steel bar 120 is inserted into the corresponding connector 140. When the inclination angle of the steel bar 120 is large, the end of the steel bar 120 conflicts with the inner wall of the connector 140. When the inclination angle of the steel bar 120 is small or the inclination angle is negligible, the end of the steel bar 120 generates a thrust on the clamping strip 170 into the connector 140. Since the movable groove 171 near the inner side of the connector 140 has space for the clamping strip 170 to rotate, the clamping strip 170 can be rotated. The end 170 of the clamping bar 170 rotates inwards, and the second torsion spring 172 is compressed at this time. When the end of the steel bar 120 passes over the clamping bar 170, so that the clamping bar 170 corresponds to the thread groove of the end of the steel bar 120, the second torsion spring 172 drives the clamping bar 170 to rotate outwards and reset under the action of the rebound force, so that the end of the clamping bar 170 and the thread groove of the end of the steel bar 120 are engaged with each other. Since the movable groove 171 near the outside of the connector 140 contacts and fits with the clamping bar 170, the clamping bar 170 cannot rotate toward the outside of the connector 140, thereby preventing the steel bar 120 from falling off from the connector 140 as much as possible, and enhancing the firmness of the connection between the steel bar 120 and the connector 140.

[0048] Then, the drill bit of the impact drill is clamped in the slot 169, so that the impact drill drives the rotating nail 163 to rotate, and the first steel wire 161 is wound around the rotating nail 163, thereby tightening the first steel wire 161 passing through the ring 162, so that the tightened first steel wire 161 produces an inward thrust on the clamping assembly 150, thereby making the clamping plate 153 close to the steel bar 120, and the clamping plate 153 rotates during the process of contact with the steel bar 120, so that the clamping plate 153 can produce adaptive angle rotation adjustment for steel bars 120 with different inclination angles, thereby facilitating the clamping of the clamping plate 153 on the steel bar 120. Moreover, when the first steel wire 161 continues to be tightened, the pressure generated by the ring 162 on the piston 155 is greater than the resistance to the rupture of the sealing film 157, so that the sealing film 157 ruptures under the enhanced pressure, thereby causing the condensed film in the cavity 154 to rupture. The solidifying agent flows into the gap between the universal ball 152 and the clamping plate 153 through the through hole 158, so that the solidifying agent solidifies and the universal ball 152 and the clamping plate 153 are bonded and fixed, so that the clamping plate 153 can no longer rotate, thereby further improving the firmness of the clamping plate 153 clamping the steel bar 120. Moreover, when the rotating nail 163 rotates, the rotating nail 163 drives the rotating drum 164 to rotate. The cooperation of the ratchet 166 and the ratchet groove 168 makes the rotating nail 163 only rotate in the direction of winding the first steel wire 161, avoiding the problem of the rotating nail 163 reversing and loosening the first steel wire 161, thereby ensuring that the first steel wire 161 remains in a tightened state, so that the clamping assembly 150 always maintains the effect of clamping and fixing the steel bar 120, and the denser the ratchet grooves 168 are, the higher the accuracy of the tightening adjustment of the first steel wire 161.

[0049] In summary, the bell-mouth design of the connector 140 improves the tolerance for the inclination of the steel bar 120, so that the steel bar 120 can be docked with the connector 140 within a reasonable inclination range, and then the driving component 160 drives the clamping component 150 to gather inward to clamp and fix the steel bar 120, thereby ensuring the stability of the connection between the steel bar 120 and the connector 140, and avoiding as much as possible the problem of the cylindrical sleeve in the prior art that often needs to be cut and re-welded, thereby effectively improving the efficiency of steel concrete slab wall construction.

[0050] It should be noted that the steel bonding glue is a two-component modified epoxy structural adhesive A and B, which has the characteristics of strong bonding strength, strong shear strength, anti-aging, good acid and alkali resistance, strong impact resistance, room temperature curing, small shrinkage during the hardening process, no flow during construction, no volatile solvents, non-toxic and easy construction. Steel bonding glue and impact drills are well known in the art and will not be elaborated here.

A slider 182 is fixedly installed at the end of the arc rod 181. A chute 183 for cooperating with the slider 182 is provided on the side of the slide rod 151 close to the slider 182. The slider 182 is slidably inserted into the chute 183, and the slider 182 is arranged as a trapezoidal block to prevent the slide rod 151 from separating and falling off from the arc rod 181. A first spring 184 is arranged in the inner wall of the adapter 140. The first spring 184 is sleeved outside the arc rod 181. The two ends of the first spring 184 are respectively fixedly connected with the inner wall of the adapter 140 and the arc rod 181.

One end of the connection hole 190 is a double-hole end, and the other end of the connection hole 190 is a single-hole end. The hole end is the turning point of the connection hole 190. The double-hole end of the connection hole 190 is close to the clamping assembly 150. Second steel wires 191 are fixedly installed on the outer sides of the slide rods 151 located on both sides of the adapter 140. The ends of the two second steel wires 191 respectively pass through the double-hole end of the connection hole 190 and then jointly pass through the single-hole end of the connection hole 190, so that the ends of the two second steel wires 191 are both located inside the adapter 140.

[0053] A threaded cylinder 200 is rotatably arranged inside the adapter 140.

A guide rod 204 is fixedly installed on the outer side of the extrusion sheet 202. A guide groove 205 for cooperating with the guide rod 204 is provided on the inner wall of the adapter 140. The guide rod 204 is slidably inserted into the guide groove 205.

[0054] Among them, the second steel wire 191 has different states under different circumstances.

[0055] For example, in some embodiments, referring to Figure 4 , Figure 5 , Figure 7 and Figure 9As shown, the second steel wire 191 can have a first state. The first state is when the second steel wire 191 is not in use. In the first state, when the steel bar 120 inserted into the connector 140 has a large inclination, the end of the steel bar 120 abuts against the inner wall of the connector 140 and does not contact the pressing piece 202, so that the pressing piece 202 cannot be pushed, and the second steel wire 191 remains stationary in its initial state. At this time, the clamping assemblies 150 on both sides of the connector 140 are still in a lower position. They can not only hold and fix the ends of the steel bar 120 that are inclined upward or downward, but also generate an upward lifting force on the inclined ends of the steel bar 120. Thus, when the connector 140 and the clamping assemblies 150 are used in cooperation, the stability of the connection of the inclined steel bar 120 is improved.

[0056] For example, in some embodiments, referring to Figure 3 、 Figure 4 、 Figure 8 and Figure 10 As shown, the second steel wire 191 can have a second state. The second state is when the second steel wire 191 is being pulled. In the second state, the second steel wire 191 is wound up by the rotating threaded cylinder 200, thereby pulling the second steel wire 191.

[0057] Next, the present disclosure will introduce the winding and pulling of the second steel wire 191 in detail in combination with the above specific embodiments. Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in, when the steel bar 120 inserted into the connector 140 is almost straight and not inclined, the steel bar 120 is inserted deep into the connector 140, generating a thrust on the pressing piece 202, causing the pressing piece 202 to drive the screw rod 201 to move into the threaded cylinder 200. By sliding the guide rod 204 in the guide groove 205, the screw rod 201 can only move horizontally backward. At this time, the second spring 203 is compressed. Through the threaded cooperation of the backward-moving screw rod 201 and the threaded cylinder 200, the threaded cylinder 200 rotates, thereby winding and rolling up the second steel wire 191 fixed on the threaded cylinder 200, so that the second steel wire 191 generates a pulling force on the clamping assemblies 150 on both sides of the connector 140;

[0058] The second steel wire 191 pulls the clamping assembly 150 upward. Meanwhile, the clamping assembly 150 drives the arc rod 181 to extend outward, and the first spring 184 is stretched, causing the second steel wire 191 to pull the two clamping assemblies 150 to move upward to the left and right sides of the connector 140 respectively, so as to clamp and fix the straight steel bar 120 in the connector 140 in a circumferentially uniform manner, enhancing the stability of the clamping of the steel bar 120 by the clamping assembly 150. When the steel bar 120 is removed from the connector 140, the thrust of the steel bar 120 on the pressing piece 202 is released. Under the action of the resilience of the first spring 184 and the second spring 203, the clamping assemblies 150 on both sides can move downward and reset.

[0059] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0060] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0061] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
