Description

Technical Field

[0001] The utility model relates to the technical field of super high-rise building construction, in particular to a core tube pre-embedded connection system. Background Art

[0002] The pre-embedded steel bar connector is the key to the reliable connection between the core tube and the outer frame of a super high-rise building. At present, in order to improve the construction efficiency in the construction process of super high-rise buildings, top formwork, sliding formwork, climbing formwork and other formwork systems are mostly used. The construction characteristics of these three systems are that the core tube and the outer frame are constructed separately. Due to the limitations of the formwork system, the outer wall of the core tube cannot be reserved in the traditional form of steel bars. The reinforced concrete outer frame beam components and the core tube need to be connected with steel bars using connectors. Once the connector is affected by the deviation, verticality, etc. that exceed the allowable error, or the finished connector is not well protected and damaged, it will have an irreversible impact on the construction. Therefore, ensuring the accuracy of the pre-embedded steel bar connector is the key to the reliable connection between the outer frame and the core tube of a super high-rise building.

[0003] For this purpose, this paper provides a core tube pre-embedded connection system. Utility Model Content

[0004] The utility model aims to provide a core tube pre-embedded connection system which is applied to the connection position between the core tube and the outer frame beam of a super high-rise building and improves the pre-embedded accuracy and quality of the connector.

[0005] The utility model is achieved through the following measures:

[0006] A core tube pre-buried connection system, characterized by comprising a connection integration system;

[0007] The docking integrated system includes a shaped steel plate arranged on the outer facade of the core tube, a plurality of connectors are arranged on the outer facade of the shaped steel plate away from the outer facade of the core tube, and a plurality of connectors are arranged on the outer ends of the connectors away from the shaped steel plate. The beam anchoring steel bars use HRBF500 grade steel bars, and short steel bars are welded at the tails to ensure that the length of the beam anchoring steel bars meets the requirements of the seismic tensile anchoring length while minimizing the length of the beam anchoring steel bars to avoid the occurrence of bent anchors, so as to facilitate the placement of the docking integrated system in the core tube structure;

[0008] The docking integration system integrates the connector on a plane, taking advantage of the verticality, flatness and non-deformation of the shaped steel plate to better control the positioning accuracy of the connector;

[0009] The integrated connection system is easy to construct and operate. It only needs to adjust the verticality and flatness of the standardized steel plate to control the accuracy of all connectors, avoid one-by-one verification, save labor costs, and greatly reduce the probability of errors.

[0010] The specific features of the utility model also include:

[0011] The shaped steel plate is provided with a plurality of through holes cooperating with the connector, the inner end of the connector is inserted into the through hole and the inner end surface of the connector is flush with the inner facade of the shaped steel plate, and the middle part of the shaped steel plate is opened to reserve the connection part between the new and old concrete.

[0012] The connector is fixed by welding to the shaped steel plate, and the plane of the shaped steel plate is perpendicular to the axis of the connector. During welding, the connector is fixed by welding after being calibrated by a laser level.

[0013] The shaped steel plate takes into account the shear key welding surface, and the beam anchor steel bar takes into account the anchor steel bar of the steel plate. The beam anchor steel bar material and construction process are optimized, thereby reducing the required length of the beam anchor steel bar, greatly saving the required materials, and avoiding the bending of the beam anchor steel bar, which facilitates the construction of the core tube structure;

[0014] The connector integration system embeds the connector, which effectively ensures the protection quality of the finished connector and prevents the connector from being exposed and affected by adverse external factors. At the same time, it can ensure that there are no protrusions in the lifting path of the mold frame system, ensuring the safety of the mold frame system lifting.

[0015] It also includes a finished product protection mechanism, which includes a protective soft plug arranged in the inner end port of the connector. Before the connector is welded to the shaped steel plate, the protective soft plug is inserted into the inner end port of the connector to protect the connector as a finished product.

[0016] The finished product protection mechanism also includes an adhesive tape, which is adhered to the inner end port of the connector where the protective plug is provided, and the adhesive tape is used to close the gap to prevent concrete slurry from flowing into the connector.

[0017] The finished product protection mechanism also includes a foam plate arranged between the outer surface of the core tube and the shaped steel plate, and the foam plate is used to prevent external adverse factors from damaging the finished connector;

[0018] The finished product protection mechanism is simple to arrange and remove, and the protective plug prevents coarse and fine aggregates from entering the connector; the tape seal prevents the inflow of concrete slurry and can protect the shear key welding area from contamination; the foam board protects the connector port to prevent sharp objects from damaging the finished connector, thereby better protecting the finished product.

[0019] A slot is provided on the side of the shaped steel plate, a bubble level is provided in the slot, the bubble level is pasted in the slot, and the bubble level includes a level bubble viewer and a water bubble provided in the level bubble viewer;

[0020] The bubble level can directly reflect the overall tilt state of the docking integrated system. Before the concrete is concealed, the docking system can be calibrated and adjusted by adjusting the inspection device.

[0021] The bubble level is used to calibrate the docking integrated system. The adjustment is stopped when the bubble is centered. Assuming that the outer facade of the core tube is the xOz plane and the axis perpendicular to the steel plate is the y-axis, the bubble level is used to calibrate all the reserved ends of the connectors on the docking integrated system to be parallel to the xOz plane. For the rotation angle of the docking integrated system around the z-axis, a laser level is used to complete the calibration.

[0022] The complete application process is:

[0023] (1) The factory produces the standardized steel plate, and holes are opened according to the position and diameter of the connector. The top of the standardized steel plate is reserved with a mounting slot for the bubble level;

[0024] (2) Transport the components to the construction site for on-site assembly;

[0025] (3) One side of the connector is connected to the beam anchor steel bar, and the other side is installed, calibrated, and welded to the through hole of the shaped steel plate. The inner end surface of the connector is flush with the inner facade of the shaped steel plate, and the plane of the shaped steel plate is perpendicular to the axis of the connector. The bubble level is calibrated and bonded to the reserved slot, the protective soft plug is inserted into the connector port, and the gap is sealed with the tape;

[0026] (4) Transport and install the assembled docking integrated system to the designated location, calibrate the bubble level so that the bubble is centered, squeeze the foam board between the shaped steel plate and the core tube outer template, and weld and fix the docking integrated system to the measure ribs;

[0027] (5) During the pouring process, continue to pay attention to the position of the bubbles, promptly detect the deviation, and make adjustments until the concrete is hidden;

[0028] (6) After the pouring is completed and the mold is removed, the foam board, the tape and the protective soft plug are removed in turn, the floating dust is cleaned, the shear key is welded on the shaped steel plate, and the connector port is connected to the connecting steel bar.

[0029] The beneficial effects of the utility model are:

[0030] The utility model integrates and modularizes the connector, and only needs to adjust the position and inclination of the steel plate, so that the position and inclination correction of the connector is more convenient, the efficiency and quality of connector installation are improved, the manpower required for connector positioning work is reduced, and the possibility of connector pre-embedded errors is greatly reduced.

[0031] The utility model takes into account the connector positioning steel plate and the shear key welding surface, and uses the beam anchoring steel bars to take into account the anchoring steel bars of the steel plate. The anchoring steel bars use HRBF500 grade steel bars, and the tail is welded with 5d steel bars of the same diameter, which can greatly reduce the length required for the steel bar anchoring and greatly save the required materials.

[0032] All connectors are pre-buried in the core tube structure, and the formwork system is not affected by protruding objects during lifting, reducing safety hazards during construction. BRIEF DESCRIPTION OF THE DRAWINGS
