Detailed description of the invention
The combination tower crane for roof construction and the construction method thereof that the present invention are proposed below in conjunction with the drawings and specific embodiments are described in further detail.According to the following describes and claims, advantages and features of the invention will be apparent from.It should be noted that, accompanying drawing all adopts the form simplified very much and all uses non-ratio accurately, only in order to convenience, the purpose aiding in illustrating the embodiment of the present invention lucidly.For sake of convenience, described below " on ", the upper and lower direction of D score and accompanying drawing consistent, but this can not become the restriction of technical solution of the present invention.
The invention provides a kind of combination tower crane for roof construction and construction method thereof, be used for solving under roof structure complex situations, it is impossible to use the plant equipment such as conventional tower crane to carry out the technical barrier of lifting construction.
Combination tower crane and the construction method thereof that the present invention constructs for roof is described in detail below in conjunction with Fig. 1 to Fig. 4.
Embodiment one
The present embodiment is for certain technological transformation project, this project high building original structure Bock Altitude is to 115.75m, owing to being subject to place and original structure restriction, outer attached tower crane and interior (outward) climbing tower crane cannot be installed, the peripheral combination tower crane installation in position using the present embodiment with the newly-increased steel construction in roof of final high building.As shown in Figures 1 to 4, a kind of combination tower crane for roof construction, including the roofing being set up in parallel hang 1 and roofing hang 2 20, roofing hangs 1 and is installed on roof 40 by bracing frame 30, roofing is hung 2 20 and is connected with roof 40 by tower crane, and tower crane includes tower body 21 and basis girder steel 22, and the upper end of tower body 21 is hung 2 20 revolutions and is connected with roofing, the lower end of tower body 21 is fixing with basis girder steel 22 to be connected, and basis girder steel 22 is fixing with roof 40 to be connected.
Specifically, for the complex working condition that each position, roof 40 end face absolute altitude of original structure is different, select two tower cranes (roofing hang 1 and roofing hang 2 20) combination use, wherein roofing hangs on one 10 roofs 40 being arranged at above the Core Walls Structure that end face absolute altitude is higher, and roofing hangs 1 and is connected by bracing frame 30 is fixing with the roof 40 above Core Walls Structure.Roofing hangs 2 20 and is positioned on the relatively low roof of end face absolute altitude 40.In order to ensure roofing hang 1 and roofing hang 2 20 combination use, roofing hangs and arranges tower body 21 between 2 20 and roof 40, thus solving the installation that under roof 40 end face Altitude difference situation, roofing hangs so that be not subject to the restriction of installation site when roofing hangs 2 10 installation.Certainly, before tower body 21 is installed, it is necessary to a load transfer device is set between tower body 21 and roof 40, in the present embodiment, girder steel 22 based on load transfer device, by the effect of basis girder steel 22, by in the power smooth transfer of tower body 21 to roof 40, thus ensureing that roofing hangs 2 20 safty hoisting constructions.This combination tower crane uses QD10 roofing to hang and hangs 2 20 as roofing and be combined into roofing with ST6015 tower body 21 and hang 2 20 and be installed on 103.8m absolute altitude place, roof, the brachium that wherein QD10 roofing hangs is 24 meters, the height of ST6015 tower body 21 is 12 meters, the lower end of 2 20 is hung by tower body 21 is installed on roofing, hang so that the roofing after improving hangs the serviceability of 2 20 more than QD10 roofing, it is possible to meet QD10 roofing and hang the construction operating mode load requirement to tower body.That is select QD10 roofing to hang and hang 2 20 as roofing, and select tower body 21 to hang the basis of 2 20 as roofing, thus meeting roofing to hang the installation requirement of 2 20 so that roofing hangs the installation of 2 20 not by the restriction of installation site.

With continued reference to Fig. 4 especially, tower body 21 welds or riveting with basis girder steel 22.QD10 tower crane hangs 2 20 as roofing, and the angle welding of its basis girder steel 22 and embedded part should be greater than being equal to 20mm, it is possible to selecting chemical anchor bolts, wherein 6M12 chemical anchor bolts are for inner side metope, and 6M20 chemical anchor bolts are for outside metope.
Accordingly, the present embodiment additionally provides a kind of construction method combining tower crane.Incorporated by reference to referring to figs. 1 to Fig. 4, the construction method of combination tower crane, comprising the following steps:
S001: roofing is hung on one 10 roofs 40 being fixedly installed in above Core Walls Structure by bracing frame 30；
S002: fixed installation basis girder steel 22 on roof 40, and tower body 21 is fixedly installed in above the girder steel 22 of basis；
S003: hang one 10 lifting roofings by roofing and hang 2 20 so that the lower revolution 26 that roofing hangs bottom 2 20 is connected with upper rotary 25 revolution of tower body 21.
Preferably, S002 also comprises the steps:
The first step, pre-buried embedded part on roof 40；
Second step, welding basis girder steel 22 on embedded part；
3rd step, welding tower body 21 above the girder steel of basis.
In sum, the combination tower crane for roof construction of the present invention, including the roofing being set up in parallel hang one and roofing hang two, roofing hangs one and is installed on roof by bracing frame, roofing is hung two and is connected with roof by tower crane, and tower crane includes tower body and basis girder steel, and the upper end of tower body is hung two-revolution with roofing and is connected, the lower end of tower body is fixing with basis girder steel to be connected, and basis girder steel is fixing with roof to be connected.The installation hung due to roofing is high to status requirement, therefore, the difficult problem of two is hung for can not install roofing by conventional methods because installation site is special, a matched tower body is set up, thus solving roofing to hang the installation difficult problem of two by when mounted the roofing originally not having supporting tower body being hung two.It is to say, by hanging one tower body of corresponding increase below two at roofing, solve under roof structure complex situations, it is impossible to use the plant equipment such as conventional tower crane to carry out the technical barrier of lifting construction.The construction method of this combination tower crane, it is first according to the usual manner good roofing of installation installation site and hangs one, then utilize the roofing installed to hang a lifting roofing and hang two, and roofing is hung the lower revolution of two turn round with the upper rotary of tower body and be connected, make roofing hang the installation of two by the restriction of installation site, thus ensure to be hung by roofing one and roofing hang the lifting work that the combination tower crane that two combinations constitute normally completes in roof modified construction.
