Description

Temporary support is installed in a kind of high-order steel truss segmentation
Technical field
This utility model relates to high-building construction technical field, is specifically related to a kind of high-order steel truss segmentation and installs temporary support.
Background technology
Along with the quickening of Urbanization in China, Civil Buildings in Cities of China is commonly available to be greatly developed, and various skyscraper becomes the main building in urban architecture and core terrestrial reference, the most various Commercial Complexes building, senior office building, star hotel etc..These high levels, high-rise building, Commercial Complex building needs due to topology layout, structure conversion and structure stress, uses steel truss structure in a large number, such as truss frame for connecting, vestibule truss, floor transfer truss and semi-girder truss etc..
Owing to the general span of steel truss structure is relatively big, Heavy Weight, affect the lifting performance of job site crane, when on-the-spot crane lifting performance is less than normal or condition limits, cannot integral hoisting to the bigger high-order steel truss of span, and segmental hoisting need to be carried out, bracing frame need to be set in bottom, segmentation position, meet segmentation installation quality, safety and convenient construction operation.Technology truss sections installs the upright bracing frame of the many employings of bracing frame or type steel support at present, this supporting construction maxi-mum height is limited, when truss installa-tion positional distance lower support plane is higher, there will be upright support frame and cannot support segmentation truss, or i.e. allow to support segmentation truss, when the highest, require and requirement for bearing capacity for meeting the slenderness ratio of bracing frame itself, need to increase bracing frame cross section, and take fixing measure to ensure stability and the safety of bracing frame itself.
Utility model content
The purpose of this utility model is to provide a kind of high-order steel truss segmentation to install temporary support, can effectively ensure that the stability of segmentation truss structure in installation process, it is to avoid truss deforms, it is ensured that the structural safety of installation process.
For achieving the above object, this utility model have employed techniques below scheme: includes steel truss, described steel truss includes horizontally disposed top boom, lower boom and the web member being connected between top boom and lower boom, the two ends of described top boom and lower boom are fixing with concrete structure column respectively to be connected, the bottom of described lower boom is respectively equipped with the steel pipe support bar tilted to both sides below, and the two ends of described steel pipe support bar removably connect with lower boom and concrete structure column respectively.
The bottom of described lower boom is provided with first connecting plate corresponding with the upper end of steel pipe support bar, described concrete structure column is provided with second connecting plate corresponding with the lower end of steel pipe support bar, and the two ends of described steel pipe support bar are connected by bolt is fixing with the first connecting plate and the second connecting plate respectively.
Angle between described steel pipe support bar and concrete structure column is not more than 70 degree.
Described second connecting plate is made up of the steel plate being close to concrete structure column and the connector that extends outwardly along steel plate side, and described steel plate is fixed with concrete structure column by expansion bolt and is connected.
As shown from the above technical solution, this utility model efficiently solves in skyscraper, owing to on-the-spot crane lifting performance is less than normal or condition limits, cannot integral hoisting to the bigger high-order steel truss of span, and segmental hoisting need to be carried out, and truss is higher away from lower support face, it is impossible to a kind of bearing diagonal arranged when arranging upright support, safety and the installation quality of in work progress structure are effectively ensured.Meanwhile, this temporary support structure is simple, and support effect is good, easy to connect, and construction cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As shown in Figure 1, 2, temporary support is installed in the high-order steel truss segmentation of the present embodiment, including steel truss, steel truss includes horizontally disposed top boom 11, lower boom 12 and the web member 13 being connected between top boom 11 and lower boom 12, the two ends of top boom 11 and lower boom 12 are fixing with concrete structure column 2 respectively to be connected, the bottom of lower boom 12 is respectively equipped with the steel pipe support bar 3 tilted to both sides below, and the two ends of steel pipe support bar 3 removably connect with lower boom 12 and concrete structure column 2 respectively.
In the present embodiment, dismantle for convenience, the bottom of this lower boom 12 is provided with first connecting plate 4 corresponding with the upper end of steel pipe support bar 3, concrete structure column 2 is provided with second connecting plate 5 corresponding with the lower end of steel pipe support bar 3, and the two ends of steel pipe support bar 3 are fixed and are connected with the first connecting plate 4 and the second connecting plate 5 by bolt respectively.Angle between this steel pipe support bar 3 and concrete structure column 2 is not more than 70 degree, forms oblique temporary support structure, to reach preferably to support firm effect.
This steel pipe support bar 3 uses round steel pipe, and concrete specification determines according to upper load and end length of encorbelmenting.Second connecting plate 5 is made up of the steel plate being close to concrete structure column 2 and the connector that extends outwardly along steel plate side, and steel plate is fixed with concrete structure column 2 by expansion bolt and is connected.
In installation process, steel pipe support bar 3 is connected on steel truss lower boom 12 lift in place in the lump with segmentation steel truss by steel truss lower edge bottom the first connecting plate 4, after in place, again by advance at the cable wind rope arranged in steel pipe support lower end, steel pipe support bar 3 bottom is led and drags to concrete structure column 2, be connected formation support system with concrete structure column 2 by the second connecting plate 5.
Temporary support is installed in the segmentation connecting the bigger floor conversion steel truss of steel truss, vestibule steel truss or span that this utility model is applicable to skyscraper position higher.Can effectively ensure that the stability of segmentation truss structure in installation process; by oblique steel pipe support bar 3, the counter-force strong point is set at segmentation truss end of encorbelmenting; the moment load of end of encorbelmenting can be offset; thus avoid truss to cause deformation because moment of flexure of encorbelmenting is excessive; and reduce the shear loads of truss and concrete column connected node, connecting joint point is effectively protected.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
