Description
Technical field
A kind of U-shaped beam is the utility model is related to, more particularly to a kind of new prefabricated U-shaped beam.
Background technology
U-shaped beam is because its combination property reduces compared with being had a clear superiority for box beam, and with building height, noise reduction effect
The advantages that good, it is widely used in urban track traffic and railway engineering, the construction of traditional prefabricated U-shaped beam, key is mould
The making and installation of plate, because U-shaped Liangqi is special formed, the manufacture difficulty of template is larger, installs also cumbersome, form removal journey
Sequence is also relatively cumbersome, and this large-scale promotion for being unfavorable for U-shaped beam uses.With the development of economy and society, urban track traffic is compeled
It is essential and wants a large amount of reliable in quality and the less prefabricated U-shaped beam of prefabricated difficulty, seeks a kind of new prefabricated U-shaped beam and its prefabricated side
The requirement of method is also just into a main trend of current construction industry, but the prefabricated U-shaped beam forms engineering that presently, there are is more or less
There are problems that.
Therefore, need that to seek a kind of new, template construct, installation, dismounting difficulty low badly at present, repeat and utilize, save into
This, green prefabricated U-shaped beam seems particularly significant.
Utility model content
The purpose of this utility model is to provide a kind of new prefabricated U-shaped beam.The purpose of this utility model is by following skill
What art scheme was realized：
New prefabricated U-shaped beam, it is mainly pre-buried by the edge of a wing, straight flange web, bottom plate, longitudinal reinforcement, transverse steel, hole for hoist
Part, prestress wire, bellows and strong concrete composition；The pre-buried L-angle steel of pedestal fixes the outer Integral mold in bottom, steel reinforcement cage and
Material cushion block is lined between template.
As preferred：The support of side form includes side form horizontal brace and side form diagonal brace, and side form horizontal brace is consolidated including sleeve gad
Determine device and sleeve.
As preferred：Integral mold bottom connection L-angle steel and jack outside bottom, side connect Integral mold diagonal brace support outside bottom,
Top surface is ined succession rack beam.
As preferred：Prestress wire is placed in bellows, and hole for hoist built-in fitting is prior to steel reinforcement cage colligation, hole for hoist
Built-in fitting is connected on positioning bar.
As preferred：Rack beam left end is ined succession crossbeam rigid support, right-hand member connecting cross beam flexible support.
The utility model has following features and beneficial effect：
Integral mold outside the bottom that the utility model uses, the globality of template can be increased, the design of hinge is also relatively more flexible,
Without the fitting sex chromosome mosaicism for considering further that bed die and external mold.
All shuttering supportings of the utility model use bolt and hinge connection, are easily installed and dismantle.
Prefabricated U-shaped beam of the present utility model uses straight flange web form, can be with the premise of Structure Calculation intensity is met
The manufacture difficulty of side form is reduced, so as to ensureing the quality of template, indirect saving cost.
Side form horizontal brace of the present utility model make use of the structure of similar bracing members, and from heavy and light, installation and dismounting are convenient, apply
Work speed is fast, can reuse (environmental protection, green).

Embodiment：
Required to carry out the making of template according to design drawing first, the bed die part of Integral mold 12 uses steel plate system outside bottom
Make, global sections are isosceles trapezoid shape, water table opening 4710mm, base square 5110mm, thickness of slab 200mm, the position at waist
Install hinge 14, exterior mold portion is welded in echelon using channel-section steel, and a waist is 200mm, and another waist length is 250mm, two long sides
Respectively 1800mm and 2200mm, upper end set pin joint, this two parts are connected by hinge 14 to be formed one outside bottom
Body mould 12, side form 13 is overall endways Z-shaped like one, and channel-section steel is welded, and the thickness of side form 13 is 200mm, upper end
Pin joint is set, eventually forms Prototype drawing as shown in Figure 3, finally carries out the making of pedestal 16, a width of 9100mm of pedestal, thickness
For 1000mm, pre-buried good L-angle steel 15, the affixed position of good bolt hole and rack beam 25 is reserved, as shown in Figure 6.
According to design drawing, pre-buried prestress wire 7, bellows 8 and hole for hoist built-in fitting 6, then added by positioning bar
Gu.Colligation is carried out to longitudinal reinforcement 4 and transverse steel 5 and obtains steel reinforcement cage, carries out the colligation of bottom plate 3 and straight flange web 2 first, most
The colligation on the edge of a wing 1 is carried out afterwards, by material cushion block 10 during colligation, thickness 35mm, arranges that colligation is adopted by spacing 600
With bifilar No. 22 iron wires, suspension centre is then laid on steel reinforcement cage, according to being calculated：Suspension centre longitudinal pitch is 1m, horizontal spacing
For 1.5m, as shown in Figure 5.
The affixed good rack beam 25 first on pedestal 16, then by the L-angle steel 15 on pedestal 16 Integral mold 12 outside bottom
It is fixed on pedestal 16, is then supported using Integral mold diagonal brace 23 outside bottom, Integral mold diagonal brace 23 is fixed on platform with bolt 24 outside bottom
On seat, opposite side, which is supported on, to be fixed on outside bottom on the support backing plate 26 on Integral mold 12, then passes through the upper end of Integral mold outside bottom 12
The pin joint that portion is set, is articulated with rack beam 25, and the arrangement support of side form 13 is similar, and simply side form diagonal brace 18 is fixed
In on rack beam 25, secondly side form horizontal brace 17 is the structure obtained by the branch sleeve of sleeve gad fixing device 19, sleeve
21 are connected by ring flange 22, and its structure is specific as shown in Figure 3 and Figure 4.
And then strong concrete 9 is poured, pours order as shown in figure 8, being vibrated when pouring, vibrating for both sides is same
Step is carried out, and pouring to be carried out continuously, and is noticed that whether the situation that slurries are spilt.
Concrete curing is carried out after the completion of pouring, the dismounting of template, specific dismounting order are carried out after prescribed strength to be achieved：
The support system of side form 13 is removed first, is then released the bolt 24 outside bottom on Integral mold 12, is then removed side form 13, shed bottom
Outer Integral mold diagonal brace 23, remove hinge 14, the outer side mold of the outer Integral mold 12 in dismounting bottom.
Need to carry out tensioning to prestress wire 7 after form removable, tension sequence is as shown in fig. 7, get out indispensability
Tensioning equipment, then carry out prestress wire 7 tensioning, specific tensioning details refers to specification, right after the completion of tensioning
Duct is in the milk, and the support on beam bottom board and bed die, the prestress wire 7 of cutting tip, opposite end are removed after the completion of grouting
Portion encapsulates, and finally obtains new prefabricated U-shaped beam, specifically as shown in figure 1, its sectional view is as shown in Figure 2.
