Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a tower crane wall-attached adaptive connection device and a construction method thereof. Background Art

[0002] With the diversification of our building forms, special-shaped buildings, large stadiums or exhibitions and other public construction projects are becoming more and more common, making it more difficult to attach tower cranes to walls. Considering the construction hoisting, building height and construction deployment, conventional tower crane attachment to the wall can no longer meet the construction requirements. However, the tower crane is a tall cantilever structure with poor stability. When it is in strong winds or typhoon weather, the tower crane is very likely to become unstable and collapse, causing huge economic losses and personal safety. According to statistics, when Typhoon Meranti passed through Xiamen in 2016, at least dozens of tower cranes under construction collapsed. The collapse of the tower crane was mostly caused by excessive bending due to stress concentration in the standard section.

[0003] In order to ensure the safety of the construction process, prevent the collapse of the tower crane at the construction site when strong winds or typhoons pass by, and ensure the hoisting stability of the tower crane, it is necessary to add a set of corresponding wall-attached connection devices to the standard section of the tower crane to improve the safety of the tower crane. Since the bottleneck of assembly technology cannot be broken through, the existing wall-attached connection devices generally include connection components that are welded or bolted to the standard section of the tower crane, and then diagonal braces are set between the connection components and the floor slab to improve the support of the standard section of the tower crane. In this way, although the standard section of the tower crane is improved to a certain extent, that is, the lateral stiffness of the tower body is improved, the setting of welding points or screw holes on the standard section will inevitably reduce the original support effect of the standard section, thereby causing the local structural stability of the standard section of the tower crane to be damaged. Therefore, when strong winds or typhoons pass by, the parts of the standard section of the tower crane where the connection components are installed still have the hidden danger of local stress concentration and buckling failure. Summary of the invention

The connecting parts include a welding part welded to the supporting steel plate, and the welding part is arranged in a cylindrical shape. One end of the welding part that is not connected to the supporting steel plate extends outward and is provided with a corresponding locking part. The locking part is arranged in a truncated cone shape that is wide inside and narrow outside, and a corresponding locking hole is arranged in the middle part of the locking part.

[0015] The fixed support seat includes a base plate, which is fixed to the floor slab by a plurality of anchor bolts.

[0021] S2: abut the right-angled outer corner of the inner steel plate of the tower crane connector against the inner side of the supporting angle steel of the tower crane, and abut the right-angled inner corner of the outer steel plate against the outer side of the supporting angle steel of the tower crane, so that the interlocking inclined surfaces of the interlocking convex edges on the inner steel plate and the extended portion of the outer steel plate are in contact;

[0022] S3: Tighten the locking bolts between the outer sides of the extensions of the inner and outer steel plates, respectively. During the tightening process of the locking bolts, the interlocking inclined surfaces of the interlocking convex edges push each other, so as to push the two sides of the inner steel plate to be respectively pressed outwardly against the inner side surface of the supporting angle steel, and push the two sides of the outer steel plate to be respectively clamped inwardly against the outer side surface of the supporting angle steel; during the tightening process, a small amount of relative displacement occurs between the locking bolts and the bolt holes on the inner and outer steel plates, so as to adapt to the locking installation of the inner and outer steel plates;

[0025] S6: The four diagonal bracing rods of the diagonal bracing mechanism are respectively connected obliquely between the outer steel plate of the tower crane connector and the fixed support seat embedded in the floor slab.

[0026] Advantages of the present invention:

[0027] 1) The tower crane connector of the present invention comprises an inner steel plate and an outer steel plate arranged in an L shape, and an extension portion extending to the outer side of the supporting angle steel of the tower crane standard section is respectively provided on both sides of the inner steel plate and the outer steel plate, and then the tower crane connector can be effectively connected in place through the intervention of the connector locking mechanism. When the locking bolts of the connector locking mechanism are locking the inner steel plate and the outer steel plate, the interlocking inclined surfaces of the interlocking convex edges thereof will contact and push each other, so as to push the inner steel plate outward to press against the inner side surface of the supporting angle steel, and push the outer steel plate inward to clamp against the outer side surface of the supporting angle steel, thereby effectively fixing and installing the tower crane connector in place, and effectively solving the problem of unsupported assembly of the tower crane connector.

[0028] That is, without welding with the supporting angle steel, without setting screw holes on the supporting angle steel, and without additional fixing mechanism, the tower crane connector can be fixed on the supporting angle steel alone, and then the diagonal brace is installed between each tower crane connector and the fixed support seat embedded in the floor slab. On the basis of not affecting the local structural stability of the tower crane standard section, the support system formed by the four corners of the tower crane body (standard section) and the floor slab is effectively realized, thereby effectively increasing the lateral stiffness of the tower crane.

[0029] 2) The tower crane connector of the present invention is further provided with a supporting steel plate on the basis of the inner steel plate, and a connecting support mechanism is further provided on the basis of the supporting steel plate. The connecting support mechanism includes a connecting structural member arranged in the middle of the four tower crane connectors. The connecting structural members are respectively and retractably equipped with corresponding tightening members at positions corresponding to the supporting steel plates of the corresponding tower crane connectors. The tightening members are respectively and tightly connected to the supporting steel plates of the corresponding tower crane connectors.

[0030] Through the intervention of the connecting support mechanism, an effective connecting support is formed inside each tower crane connector, so that the force of each tower crane connector can be transmitted to different tower crane connectors in time, and then transmitted to the corresponding diagonal braces and floor slabs through the tower crane connectors, so as to prevent the supporting angle steel of the tower crane standard section from buckling and failure due to local stress concentration.

[0031] 3) The tower crane connector of the present invention is fixed to the periphery of the supporting angle steel of the tower crane standard section in a covering manner. During the process of dispersed transmission of its force through the connecting support mechanism, it will not be directly transmitted to the supporting angle steel. This also further solves the problem of direct transmission of force to the supporting angle steel of the tower crane standard section when welding or bolt connection is adopted, thereby further reducing the damage to the local structural stability of the tower crane standard section, so as to further enhance the practical effect of the present invention.

[0032] 4) The present invention has connectors welded in the middle of the supporting steel plate of the tower crane connector. The connectors are made of wrought iron material. The connectors include a welding portion welded to the supporting steel plate. The end of the welding portion that is not connected to the supporting steel plate extends outward and is provided with a corresponding locking portion. The locking portion is arranged in a truncated cone shape that is wide inside and narrow outside, and a corresponding locking hole is arranged in the middle of the locking portion. The side walls of the locking portion are also provided with corresponding clearance grooves at equal intervals. In this way, when the top clamping rod of the top clamping member is connected to the bottom of the locking hole of the locking portion, the connector at the bottom of the locking hole will be squeezed, thereby causing it to produce a concave deformation, so that the locking portion is inwardly tilted and clamped to the side wall of the top clamping rod, which can not only facilitate the installation of the connection support mechanism, but also effectively ensure the overall connection effect of the connection support mechanism and the tower crane connector after assembly, so as to further ensure the overall assembly stability of the present invention and effectively improve the force dispersion transmission effect of each tower crane connector.

[0033] 5) The connecting structure of the present invention comprises a first connecting rod, and corresponding welded steel plates are respectively fixed vertically outward on the upper and lower end surfaces on both sides of the middle part of the first connecting rod, and corresponding second connecting rods are respectively fixed outwardly through the first pin shaft between the welded steel plates, and the inner end of the second connecting rod abuts against the middle part of the first connecting rod, and the tensioning parts are respectively telescopically installed on the outer ends of the corresponding first connecting rod and the second connecting rod. Through the intervention of the welded steel plate and the first pin shaft, the detachable installation of the second connecting rod is effectively realized without affecting the supporting effect, so as to facilitate the installation of the connecting support mechanism in the standard section of the tower crane with limited space, so as to effectively further enhance the practical effect of the present invention.

[0034] 6) Due to the improved design of the tower crane connector's own structure, the present invention effectively realizes that during the installation and construction process of the present invention, the tower crane connector can be independently and firmly installed in advance without welding or bolt connection, so as to facilitate the subsequent installation and construction of the diagonal brace and the connecting support mechanism; and through the intervention of the connecting piece and the improved design of the connecting support mechanism's own structure, the connecting support mechanism can be effectively installed conveniently and stably, and the connection effect between the connecting support mechanism and the tower crane connector after installation is effectively improved, thereby effectively reducing the difficulty of construction and installation.

[0044] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0045] Please refer to Figure 1-9 , a tower crane wall-attached adaptive connection device, comprising

[0046] Four tower crane connectors 1 are respectively connected to four supporting angle steels 2 of the tower crane standard section, and the tower crane connector 1 comprises an inner steel plate 101 and an outer steel plate 102 arranged in an L shape, and the inner steel plate 101 and the outer steel plate 102 are respectively abutted against the inner and outer side surfaces of the supporting angle steel 2, and the inner steel plate 101 and the outer steel plate 102 are respectively integrally formed on both sides and are provided with an extension portion extending to the outer side of the supporting angle steel 2, and the inner angle portion of the inner steel plate 101 is transversely fixedly connected with a corresponding supporting steel plate 103;

[0047] The connector locking mechanism 3 comprises an interlocking convex edge 301 fixed to the inner side of the extension part of the inner steel plate 101 and the outer steel plate 102 of each tower crane connector 1, and corresponding interlocking inclined surfaces are respectively provided on the outer side surface of the interlocking convex edge 301 of the inner steel plate 101 and the inner side surface of the interlocking convex edge 301 of the outer steel plate 102. The outer sides of the extension parts of the inner steel plate 101 and the outer steel plate 102 are respectively locked by a plurality of groups of corresponding locking bolts 302. During the locking process of the locking bolts 302, the interlocking inclined surfaces of the interlocking convex edge 301 contact and push each other, so as to push the inner steel plate 101 outwardly to press against the inner side surface of the supporting angle steel 2, and push the outer steel plate 102 inwardly to clamp against the outer side surface of the supporting angle steel 2.

[0048] The diagonal bracing mechanism 4 comprises four diagonal bracing rods 401 obliquely connected between the tower crane connector 1 and the floor 12, the upper ends of the diagonal bracing rods 401 are connected to the right angle of the outer steel plate 102 of the tower crane connector 1, and the bottom ends of the diagonal bracing rods 401 are connected to the fixed support seat 402 pre-buried on the floor 12;

[0049] The connecting support mechanism 5 includes a connecting structure 501 arranged in the middle of the four tower crane connectors 1, and the connecting structure 501 is telescopically installed with corresponding tightening members 502 at positions corresponding to the supporting steel plates 103 of the corresponding tower crane connectors 1, and the tightening members 502 are respectively tightened and connected to the supporting steel plates 103 of the corresponding tower crane connectors 1.

[0050] When the locking bolts 302 of the connector locking mechanism 3 are locking the inner steel plate 101 and the outer steel plate 102, the interlocking inclined surfaces of the interlocking convex edges 301 will contact and push each other, so as to push the inner steel plate 101 outwardly to press against the inner side surface of the support angle steel 2, and push the outer steel plate 102 inwardly to clamp against the outer side surface of the support angle steel 2, thereby effectively fixing and installing the tower crane connector 1 in place, so as to effectively solve the assembly problem of the tower crane connector 1. That is, the tower crane connector 1 can be fixed on the support angle steel as a whole without welding with the support angle steel 2, without setting screw holes on the support angle steel 2, and without additional fixing mechanisms, and then the diagonal brace rod 401 is installed between each tower crane connector 1 and the fixed support seat 402 pre-buried on the floor 12. On the basis of not affecting the local structural stability of the standard section of the tower crane, the support system formed by the four corners of the tower crane body (standard section) and the floor slab is effectively realized to effectively increase the lateral stiffness of the tower crane.

[0051] Through the intervention of the connecting support mechanism 5, the connecting support is effectively formed inside each tower crane connector 1, so that the force of each tower crane connector 1 can be timely transmitted to different tower crane connectors 1, and transmitted to the corresponding diagonal brace rods 401 and floor 12 through the tower crane connector 1, so as to prevent the support angle steel 2 of the tower crane standard section from buckling and failure due to local stress concentration. In addition, the tower crane connector 1 of the present invention is fixed to the periphery of the support angle steel 2 of the tower crane standard section in a covering manner, and its force is not directly transmitted to the support angle steel 2 during the process of dispersed transmission through the connecting support mechanism 5, which further solves the problem of force being directly transmitted to the support angle steel 2 of the tower crane standard section when welding or bolt connection is adopted, thereby further reducing the damage to the local structural stability of the tower crane standard section.

[0052] The middle part of the supporting steel plate 103 of the tower crane connector 1 is respectively welded with a corresponding connecting piece 6, and the connecting piece 6 is made of wrought iron material. The connecting piece 6 includes a welding portion 601 welded to the supporting steel plate, and the welding portion 601 is arranged in a cylindrical shape. The end of the welding portion 601 not connected to the supporting steel plate 103 extends outward and is provided with a corresponding locking portion 602. The locking portion 602 is arranged in a truncated cone shape that is wide inside and narrow outside, and a corresponding locking hole is provided in the middle part of the locking portion 602. The side wall of the locking portion 602 is also provided with corresponding clearance grooves 7 at equal intervals.

[0053] The connecting structure 501 includes a first connecting rod 5011, and corresponding welded steel plates 5012 are respectively fixed vertically outward on the upper and lower end surfaces on both sides of the middle part of the first connecting rod 5011, and corresponding second connecting rods 5013 are respectively fixed outwardly through the first pin shaft 8 between the welded steel plates 5012, and the inner end of the second connecting rod 5013 abuts against the middle part of the first connecting rod 5011, and the tightening member 502 can be telescopically installed on the outer end of the corresponding first connecting rod 5011 and the second connecting rod 5013.

[0054] The tightening member 502 includes a tightening screw 5021 which is connected to the outer ends of the first connecting rod 5011 and the second connecting rod 5013 by a threaded connection. The head of the tightening screw 5021 is fixedly connected to the outside with a tightening rod 5022 which has a shape that matches the locking hole of the locking portion 602 of the connecting member 6. The tightening rod 5022 is tightly connected to the bottom of the locking hole of the locking portion 602, and the locking portion 602 is covered and abutted against the side wall of the tightening rod 5022.

[0055] When the jacking rod 5021 of the jacking member 502 is tightly connected to the bottom of the locking hole of the locking part 602, the connecting member 6 at the bottom of the locking hole will be squeezed, thereby causing it to deform inwardly, so that the locking part 602 is inwardly tilted and clamped to the side wall of the jacking rod 5021, which can not only facilitate the installation of the connection support mechanism 5, but also effectively ensure the overall connection effect of the connection support mechanism 5 and the tower crane connector 1 after assembly, so as to further ensure the overall assembly stability of the present invention and effectively improve the force dispersion transmission effect of each tower crane connector 1. In addition, the present invention can effectively realize the detachable installation of the second connection rod 5013 without affecting the support effect through the intervention of the welding steel plate 5012 and the first pin shaft 8, so as to facilitate the installation of the connection support mechanism 5 in the standard section of the tower crane with limited space, so as to effectively further improve the practical effect of the present invention.
