Abstract
The utility model provides a wall attaching frame structure for a self-elevating tower crane. The wall attaching frame structure for the self-elevating tower crane has the advantages that brace struts can be lighter and thinner in case of equal length, so that the cost is reduced, and the difficulty in construction is reduced. The wall attaching frame structure comprises a tower body, a wall attaching frame, brace struts and supporting seats, wherein the brace struts include inner brace struts and outer brace struts, the supporting seats are supported on a building, the wall attaching frame is arranged outside the tower body, and the inner and outer brace struts are respectively arranged between the wall attaching frame and all corresponding supporting seats. The wall attaching frame structure is characterized in that the middle parts of the inner and outer brace struts corresponding to each supporting seat are connected through a connecting rod.
Description
Technical field
The utility model relates to the technical field of structures of tower crane, is specially a kind of wall-attached frame structure for tower crane.
Background technology
The setting height(from bottom) of self-raising tower crane surpasses after its unattached height, must be connected on the bearing of building by wall-attached frame, makes tower body firm.Fig. 1 is conventional wall-attached frame version, and tower body and building wall distance are generally at 3～6 meters.
Due to the restriction of building operation place condition, or the contour structures reason of building itself, or the objective factors such as requirement of construction technology, make construction site often run into tower body and building wall distance is far, even over 10 meters.Due to strut be subject to end reaction (axial force), from the effect of gravity, horizontal wind-force, direct result is, it is and the member of long massiveness that it has not only increased cost, has also increased difficulty of construction that attached wall strut tends to.
Summary of the invention
For the problems referred to above, the utility model provides a kind of wall-attached frame structure for tower crane, and it makes the strut can be gentlier thinner under equal length, has saved cost, and has reduced difficulty of construction.
A kind of wall-attached frame structure for tower crane, its technical scheme is such: it comprises tower body, attached wall framework, strut, bearing, described strut comprises internal overarm support, outer strut, described bearing support is on building, described tower body outer setting has attached wall framework, between each bearing of described attached wall framework and correspondence, be provided with internal overarm support, outer strut, it is characterized in that: between the medium position of the corresponding internal overarm support of each bearing, outer strut, by connecting rod, connect.
It is further characterized in that: the opposite side of the corresponding medium position of the corresponding described internal overarm support of each bearing, outer strut is welded with respectively otic placode, and the two ends of described connecting rod are anchored on the otic placode of corresponding described internal overarm support, outer strut by bearing pin respectively.
Adopt after structure of the present utility model, between medium position due to the corresponding internal overarm support of each bearing, outer strut, by connecting rod, connect, improved the strength and stability of strut bending-resistant, thereby can reduce the structural section of strut, the corresponding impact that has reduced to be subject to wind-force, it makes the strut can be gentlier thinner under equal length, has saved cost, and has reduced difficulty of construction.
Accompanying drawing explanation
Fig. 1 is existing wall-attached frame structural representation;
Fig. 2 is front view structural representation of the present utility model;
Fig. 3 is the local structure for amplifying schematic diagram at the A place of Fig. 2.
The specific embodiment
See Fig. 2, Fig. 3, it comprises tower body 1, attached wall framework 2, strut, bearing 3, strut comprises outer strut 4, internal overarm support 5, bearing 3 is supported on building 6, tower body 1 outer setting has attached wall framework 2, between each bearing 3 of attached wall framework 2 and correspondence, be provided with outer strut 4, internal overarm support 5, the corresponding outer strut 4 of each bearing 3, between the medium position of internal overarm support 5, by connecting rod 7, connect, its concrete connection structure is as follows: the corresponding outer strut 4 of each bearing 3, the opposite side of the corresponding medium position of internal overarm support 5 is welded with respectively otic placode 8, the two ends of connecting rod 7 are anchored on corresponding outer strut 4 by bearing pin 9 respectively, on the otic placode 8 of internal overarm support 5.
