Description

Technical Field

[0001] The utility model relates to the technical field of tower crane installation in building construction, and more specifically to a core tube tower crane attachment device. Background Art

[0002] The core tube is the central part of the building, which is surrounded by elevator shafts, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms to form a central core tube, which forms an outer frame inner tube structure with the outer frame and is cast with reinforced concrete. There are two types of core tubes: the hollow core tube composed of reinforced concrete dense columns and the solid core tube of reinforced concrete shear wall type. The core tube structure is very conducive to structural stress and has excellent earthquake resistance. It is the mainstream structural form widely used in super high-rise buildings in the world. At the same time, the advantage of this structure is that it can strive for as wide a usable space as possible, so that various auxiliary service spaces are concentrated in the center of the plane, so that the main functional space occupies the best lighting position, and achieves good sight and convenient internal transportation.

[0003] Tower cranes, also known as tower cranes, are the most commonly used lifting equipment on construction sites. They are mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. In the current steel tube concrete frame-reinforced concrete core tube system construction project, due to the discontinuity between the core tube and the steel frame construction, the core tube construction progress will far exceed the steel frame construction progress, resulting in the independent height of the tower crane being unable to meet the core tube construction requirements. Therefore, the tower crane needs to be attached and then lifted to ensure its operating height. However, the progress of the steel frame is slower than that of the core tube construction and cannot meet the attachment conditions. The tower crane needs to be attached to the core tube.

[0004] Therefore, how to provide a core tube tower crane attachment device to attach the tower crane to the high-rise core tube to ensure that the operating height of the tower crane meets the requirements of construction and avoid the occurrence of progress delays caused by the slow progress of the steel frame and the inability of the tower crane to jack up on schedule is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a core tube tower crane attachment device, which attaches the tower crane to the core tube to meet the jacking requirements of the tower crane, while not affecting the construction of the steel frame outside the core tube, thereby solving the problem that the core tube and its external steel frame construction are not synchronized, and the steel frame construction is delayed and cannot meet the jacking requirements of the tower crane.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A core tube tower crane attachment device attaches the tower crane to the outer wall of the core tube, including an attachment frame, an attachment truss and an attachment horizontal tie rod:

[0008] The attachment frame is sleeved on the outer wall of the standard section of the tower crane; the two groups of attachment trusses are pinned one by one to the opposite side walls of the core tube; the attachment horizontal tie rod includes a first tie rod, a second tie rod and a third tie rod, and the two ends of the first tie rod, the second tie rod and the third tie rod are pinned to the end of the attachment frame and the attachment truss, so that two triangular support structures are formed between the tower crane and the end face of the core tube relative to the tower crane.

[0009] The beneficial effect of the above technical solution is that the attachment and connection with the physical structure of the core tube are achieved by attaching horizontal tie rods respectively, so as to meet the attachment support requirements after the tower crane is lifted. The pin connection method can adjust the angle of the attachment horizontal tie rods to meet the adjustment of the verticality of the tower crane without affecting the construction of the steel frame outside the core tube. At the same time, it can also meet the lifting of the tower crane, solving the problem that the core tube and its external steel frame cannot be constructed synchronously and thus affecting the lifting of the tower crane. The tower crane and the core tube are attached and supported by two inverted triangular knots, thus ensuring the overall stability of the tower crane after the lifting.

[0010] Preferably, the attachment frame comprises a main beam, a clamp, a diagonal brace and a first double-hole ear plate;

[0011] The four main beams are connected end to end to form a square outer frame and clamped on the outer wall of the standard section of the tower crane; multiple clamps are arranged on the inner side of the square outer frame and respectively clamped on two adjacent main beams, and the clamps include two pin plates and a connecting plate, one end of the two pin plates are pinned to the end of the two adjacent main beams one by one, and the two ends of one side wall of the connecting plate are respectively fixed to the other ends of the two pin plates; the two ends of the diagonal brace are respectively pinned to the other side wall of the connecting plate at the diagonal position of the square outer frame; multiple first double-hole ear plates are respectively fixed on the outer walls of the four corners of the square outer frame to pin the attached horizontal pull rod.

[0012] The beneficial effect of the above technical solution is that the main beam is connected by clamp pins, which is convenient for installation and disassembly. The diagonal brace improves the stability and force-bearing performance of the attachment frame, preventing the attachment frame from deforming under the tensile stress of the attachment horizontal tie rod. The two ear plate holes on the first double-hole ear plate can connect at least two attachment horizontal tie rods, meeting the requirements of tower crane attachment tensioning and positioning.

[0013] Preferably, it also includes an outer frame wedge, a clamp wedge and a pad. The outer frame wedge is fixed on the inner wall of the end of the main beam, and two outer frame wedges opposite to two adjacent main beams form a wedge groove; one end of the clamp wedge is fixed on the side wall of the connecting plate away from the diagonal brace, and the other end is inserted into the wedge groove; the pad is provided between the clamp wedge and the wedge groove. Since the pin connection is unstable, the clamp is limited by the wedge to ensure the stability of the clamp connecting the two adjacent main beams and prevent the deformation of the attachment frame.

[0014] Preferably, the attachment truss comprises a first attachment truss and a second attachment truss;

[0015] The first attachment truss comprises a first square steel and a first connecting square steel, wherein the first square steel is arranged perpendicular to the first side wall and one end of the first square steel is pin-connected to the pin shaft ear plate at the first side wall close to the tower crane, and the other end of the first square steel is fixed with a three-hole ear plate; one end of the first connecting square steel is pin-connected to the three-hole ear plate, and the other end is pin-connected to the pin shaft ear plate at the first side wall away from the tower crane;

[0016] The second attachment truss comprises a second square steel and a second connecting square steel; the second square steel is arranged perpendicular to the second side wall and one end of the second square steel is pinned to the pin lug plate on the side of the second side wall close to the tower crane, and the other end of the second square steel is fixed with a second double-hole lug plate; one end of the second connecting square steel is pinned to the second double-hole lug plate, and the other end penetrates into the tongue and groove of the second side wall away from the tower crane and is pinned to the pin lug plate on the inner wall of the core tube;

[0017] Among them, one end of the first pull rod is pinned to the first double-hole ear plate arranged on the first side wall of the attachment frame, and the other end is pinned to the three-hole ear plate; one end of the second pull rod is pinned to the first double-hole ear plate arranged on the second side wall of the attachment frame, and the other end is pinned to the second double-hole ear plate; one end of the third pull rod is pinned to the first double-hole ear plate arranged on the second side wall of the attachment frame, and the other end is pinned to the three-hole ear plate.

The two triangular structures are used to attach and support the tower crane, thereby ensuring the stability of the tower crane lifting. At the same time, the embedded steel plate on the outer wall of the core tube is used to bolt the pin shaft ear plate, and the attachment device is fixed to the outer wall of the core tube by pinning the attached horizontal tie rod to the pin shaft ear plate, thereby avoiding the problem of being unable to provide an attachment working surface for the tower crane lifting due to the delayed construction of the steel frame outside the core tube.

[0019] Preferably, a tongue and groove is formed on the second side wall, a wall is fixed perpendicular to the inner wall surface of the second side wall, an embedded steel plate is provided perpendicular to the wall, the exposed side of the embedded steel plate is threadedly connected with the pin shaft ear plate, and the wall is located on the side of the tongue and groove away from the tower crane;

[0020] One end of the second pull rod away from the attachment frame penetrates into the tongue and groove and is pin-connected with the pin shaft ear plate on the wall.

The connection method of the two attached trusses along the two side walls of the core tube is not a completely symmetrical structure, and the attached trusses and the side walls of the core tube form a triangular supporting structure to ensure that the two attached trusses have sufficient anchoring performance. After the attached horizontal pull rod is connected, it can provide sufficient tensile stress to support the jacking height of the tower crane, thereby ensuring the safety factor of the tower crane jacking.

[0022] Preferably, the first tie rod, the second tie rod and the third tie rod have the same structure and both ends of the rod bodies are rotatably connected with a lead screw, and the end of the lead screw away from the rod body is fixed with a connecting ear plate pinned to the first double-hole ear plate. By rotating the lead screw, the length of the lead screw protruding from the rod body can be adjusted, and then the length of the attached horizontal tie rod can be adjusted. In the case of position error of the embedded steel plate, the tower crane attachment requirement can be met by adjusting the length of the attached horizontal tie rod.

[0023] Preferably, the pin lug is made of Q235 steel plate, and the thickness of the steel plate is not less than 16 mm, so as to meet the connection requirements of the attached truss and improve the anchoring performance of the attached horizontal tie rod.

[0024] Preferably, the number of the attachment frames on each standard section of the tower crane is three, and the distance between the attachment frames at both ends and the standard section lifting device is not less than 50 mm. Since the tower crane standard parts do not correspond to the floor height of the core tube, multiple attachment frames are set to meet the core tube drop and the height difference of the tower crane standard section. The attachment horizontal tie rod is preferably set on the attachment frame located in the middle position. When adjusting the verticality of the tower crane, the length of the attachment horizontal tie rod can be adjusted or the attachment tie rod can be moved up or down by one attachment frame to ensure that the verticality of the tower crane meets the requirements.

[0057] In order to further optimize the above technical solution, the attachment truss 3 includes a first attachment truss 31 and a second attachment truss 32;

[0058] The first attachment truss 31 includes a first square steel 311 and a first connecting square steel 312. The first square steel 311 is arranged perpendicular to the first side wall 41 and one end of the first square steel 311 is pinned to a pin lug 43 on the first side wall 41 close to the tower crane. The other end of the first square steel 311 is fixed with a three-hole lug 313.

[0059] The second attachment truss 32 includes a second square steel 321 and a second connecting square steel 322; the second square steel 321 is arranged perpendicular to the second side wall 42 and one end of the second square steel 321 is pinned to a pin lug 43 on the second side wall 42 close to the tower crane, and the other end of the second square steel 321 is fixed with a second double-hole lug 323; one end of the second connecting square steel 322 is pinned to the second double-hole lug 323, and the other end penetrates into the tongue and groove of the second side wall 42 away from the tower crane and is pinned to the pin lug 43 on the inner wall of the core tube 4;

[0060] One end of the first pull rod 21 is pin-connected to the first double-hole ear plate 17 arranged on the first side wall 41 of the attachment frame 1, and the other end is pin-connected to the three-hole ear plate 313;

[0061] One end of the second pull rod 22 is pin-connected to the first double-hole ear plate 17 arranged opposite to the second side wall 42 of the attachment frame 1, and the other end is pin-connected to the second double-hole ear plate 323;

[0062] One end of the third pull rod 23 is pin-connected to the first double-hole ear plate 17 arranged opposite to the second side wall 42 of the attachment frame 1 , and the other end is pin-connected to the three-hole ear plate 313 .

[0063] like Figures 4 to 8 As shown, a right-angled triangle support structure is formed between the first square steel, the first connecting square steel and the first side wall, and a right-angled triangle support structure is also formed between the second square steel, the second connecting square steel and the second side wall, so as to ensure that the attached truss has sufficient stability;

[0064] A triangular structure is formed between the first tie rod, the third tie rod and the main beam of the attachment frame, and a triangular structure is formed between the second tie rod, the third tie rod and the end face of the core tube. The two triangular structures are used to attach and support the tower crane, thereby ensuring the stability of the tower crane's lifting.

The attachment horizontal tie rod is preferably set on the attachment frame located in the middle position. When the verticality of the tower crane cannot be met by adjusting the length of the attachment horizontal tie rod, the position of the attachment horizontal tie rod on the standard section of the tower crane is adjusted, that is, the position of the attachment horizontal tie rod in the middle attachment frame is moved to the attachment frame at the upper or lower part of the standard section of the tower crane, so as to adjust the overall verticality of the tower crane.

[0072] In order to further optimize the above technical solution and ensure that the attachment truss has sufficient length, the attachment truss 3 is made of Q235 square steel with a cross-sectional size of 300*300*8mm.

[0073] In order to further optimize the above technical solution, the first tie rod 21 , the second tie rod 22 and the third tie rod 23 are all composed of multiple sections of standard tie rods combined by bolts 26 .

[0074] Multiple standard sections are connected by bolts, which makes it easy to install and disassemble the attached horizontal tie rods, and the length of the attached horizontal tie rods is greater than the distance between the tower crane and the core tube.

[0075] In order to further optimize the above technical solution, the lattice column with a standard tie rod section of 600*600mm is welded with 90*90*10mm angle steel. It is easy to process and manufacture, and can be made from local materials, reducing construction costs.

[0076] The installation steps of the tower crane attachment device of the utility model are:

[0077] 1) Installation of attached trusses: After the concrete strength of the embedded steel plate embedded point of the core tube reaches more than 80%, hoist the attached trusses and pin the attached trusses to the pin lugs;

[0078] 2) Installation of attachment frame: Check the deformation, open welding and cracks of the attachment frame, attachment horizontal tie rod and tower crane standard section at the installation position of the attachment device. If they meet the requirements, clamp the main beams on the tower crane standard section in sequence through clamps. Note that the four main beams should be on the same horizontal plane;

[0079] 3) Installation of the attached horizontal tie rod: adjust the lengths of the first tie rod, the second tie rod and the third tie rod according to the calculated lengths on the ground, hoist them to their respective positions, and fix both ends with double-cone pins. The attached horizontal tie rod should be installed on the attachment frame in the middle position first;

[0080] 4) Verticality check: Use a theodolite to check the verticality of the tower crane. If it does not meet the requirements, adjust the position of the connecting ear plate on the screw and then adjust the length of the attached horizontal tie rod. Use the supporting force of the attached horizontal tie rod to adjust the verticality of the tower body until the lateral verticality of the tower body is within 4 / 1000 (the verticality of the tower body above the attachment frame is 4 / 1000, and the verticality of the tower body below the attachment frame is less than 2 / 1000); when the attached horizontal tie rod does not meet the verticality adjustment requirements of the tower body, move the position of the attached horizontal tie rod up or down by one attachment frame position, and adjust the verticality in turn.
