Abstract
The utility model discloses a kind of large span without huge bandy truss pull bar, including the bandy truss being connected between two colossal columns is depended on, reinforcing pull rod is respectively equipped between bandy truss and two colossal columns.Reinforcing pull rod is drawn between the colossal column above the lower edge and bandy truss of bandy truss.Reinforcing pull rod uses section for Φ 203*12 steel pipe, and connection otic placode is set respectively in the node location of colossal column and bandy truss, and reinforcing pull rod is connected with connection otic placode using bearing pin.Set by designing reinforcing pull rod drawing, it is possible to achieve large span solves below heavy steel member without support installation problem without huge bandy truss Fast Installation is depended on, while reducing setting up for a large amount of support jigs, reduces engineering time and construction cost.
Description
Technical field
The utility model is related to a kind of huge bandy truss, more particularly to a kind of large span is drawn without huge bandy truss is depended on
Bar.
Background technology
Huge bandy truss planar dimension is huge, and internal cavity division numbers are more and butt weld quantity is more, construction segmentation
Mainly consider following factor：
(1) the lifting weight of segmenting unit, if on-site hoisting requirement can be met；
(2) weight and three-dimensional dimension of segmenting unit, if meet highway transportation requirement；
(3) the splicing welding joint position between segmenting unit, if facilitate Site Welding.
Consider and the live concatenation unit of huge bandy truss is divided after various factors, it is considered to installation process
The influence constructed to construction segmentation.
As shown in figure 1, without the nearly 40m of huge truss bottom headroom height is depended on, if setting up scaffold or tire when installing truss
Frame, in the prior art, the truss high-altitude dissipate spelling order and are：First by two sections of lower booms overhead connection install, by web member with it is upper
Chord member, into " K " font, proceeds by " K " font type lifting component, lifting sequence is in installation on ground after the completion of lower boom docking
Close up successively from truss two ends to centre.
The shortcoming of above-mentioned prior art is：
Because free height is higher below bandy truss, the method for setting up support frame from the first floor is comparatively laborious, and need to expend big
The support frame of amount, it is necessary to measure cost it is higher, and the relatively cumbersome and duration of constructing is longer.
The content of the invention
The purpose of this utility model is to provide a kind of large span without depending on huge bandy truss pull bar.
The purpose of this utility model is achieved through the following technical solutions：
Large span of the present utility model is without depending on huge bandy truss pull bar, including the band being connected between two colossal columns
Shape truss, reinforcing pull rod is respectively equipped between the bandy truss and two colossal columns.
It can be seen from the technical scheme that above-mentioned the utility model is provided the utility model embodiment provide large span without
Huge bandy truss pull bar is depended on, quick-assembling, economy expense can be achieved, and with good security, it is adaptable to it is super
It is being segmented of long, super-heavy component, fixed and weld, and to particularly useful without huge bandy truss construction is depended on below large span,
Equally there is good reference value to other similar Construction of Steel Structure, the efficiency of installation can be not only improved, moreover it is possible to for construction
The abundant time is won, standardization can be also realized, the purpose of cost efficiency is reached.

Embodiment
The utility model embodiment will be described in further detail below.
Large span of the present utility model is without depending on huge bandy truss pull bar, and its preferably embodiment is：
Including the bandy truss being connected between two colossal columns, set respectively between the bandy truss and two colossal columns
There is reinforcing pull rod.
The reinforcing pull rod is drawn between the colossal column above the lower edge and bandy truss of the bandy truss.
The drawing of the firm pull bar sets lower edge and web member connecting node position of the position as bandy truss.
The reinforcing pull rod uses section for Φ 203*12 steel pipe, in the node position of the colossal column and the bandy truss
Put and connection otic placode is set respectively, the reinforcing pull rod is connected with the connection otic placode using bearing pin.
Specific embodiment：
As shown in Fig. 2 a, Fig. 2 b, large span of the present utility model is without depending on huge bandy truss pull bar, with reinforcing pull rod by purlin
Frame lower edge oblique pull is on the colossal column of both sides.To avoid reinforcing pull rod from influenceing the lifting construction of truss web and upper cord member, reinforcing pull rod
Draw and be located at the truss lower edge left and right sides, when the lifting of truss lower edge is in place, is drawn and carried out on the colossal column at two ends using pull bar
It is fixed, it is because a level post and girder steel are arranged at truss bottom, secondary post and girder steel and the truss lower edge of bottom is laggard in installation on ground
Row lifting, both sides truss lower edge lifting is completed and the truss lower edge lifting of interlude is carried out after the completion of being fixed with pull bar, and pull bar is drawn
If position is truss lower edge and web member connecting node position.
Reinforcing pull rod section form and joint form：
As shown in Figure 3 a, 3 b, reinforcing pull rod uses section for Φ 203*12 steel pipe, in colossal column and panel point position
Connection otic placode is set, and pull bar is connected with truss and colossal column using bearing pin.
Large span of the present utility model is set by designing reinforcing pull rod drawing, realized big without huge bandy truss pull bar is depended on
Span has won the initiative of construction without huge bandy truss Fast Installation is depended on, and solves highway transportation and welding side
The problem in face, saves working measure expense, and is provided convenience condition for site operation.Also in installation rate, construction coordination
Unprecedented perfect adaptation has been reached, and good practicality effect is served to Promoting Standardized construction.Solve large-scale
Problem is installed without support below steel member, while reducing setting up for a large amount of support jigs, reduces the engineering time and is constructed into
This.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by the protection domain of claims.
