Fig. 2-Fig. 6 shows a kind of Cable stayed Bridge Main Tower of embodiment of the utility model and the construction system of steel anchor beam, cable-stayed bridge
King-tower includes the first tower body 1 and the second tower body 2, and the corresponding cable guard arm in position is arranged at intervals on the first tower body and the second tower body
3 and armored concrete corbel 4；Cable stayed Bridge Main Tower includes more than two king-tower merogenesis；King-tower merogenesis is equipped between the upper and lower every setting
Lower part corbel 41 and top corbel 42；Steel anchor beam 5 is located at 2 on the first tower body 1 and the second tower body；
Construction system includes：Pre-embedded steel slab 6, king-post steel inner template 9 and steel anchor beam falsework 8；
As shown in figure 4, pre-embedded steel slab 6 is arranged in the top surface of corbel, pre-embedded steel slab 6 passes through WELDING STUDS 7 and corbel steel bar welding
It connects；In a specific embodiment, the length dimension of pre-embedded steel slab 6 is smaller 20mm~60mm than the length dimension of joist top surface, in advance
The width dimensions for burying steel plate 6 are equal with the width dimensions of joist top surface；The length of WELDING STUDS 7 is 150mm~220mm；For example, cutting
Power nail is using 22 round ends of φ weldering nail, long 200mm, spacing 200mm；
King-post steel inner template 9 is arranged between lower part joist top surface and top joist bottom surface, using connection reinforcing bar and king-tower
The main reinforcement of merogenesis is welded and fixed；In a specific embodiment, king-post steel inner template 9 is the steel plate by preservative treatment, steel plate
Thickness be 10mm~20mm；The height of king-post steel inner template 9 be equal between lower part joist top surface and top joist bottom surface away from
From；
As shown in figure 3, the lower part of steel anchor beam falsework 8 is mounted on existed building flat surface or completed steel anchor beam top
On plate, the top surface of steel anchor beam falsework 8 is flushed with the pre-embedded steel slab 6 installed on the joist top surface of lower part；Before concreting
Steel anchor beam corresponding with lower part joist is installed on steel anchor beam falsework 8, steel anchor beam waits for king-tower merogenesis concrete with pre-embedded steel slab
It is in place that completion is welded to connect after cast.
As shown in Fig. 2, Cable stayed Bridge Main Tower includes the first king-tower merogenesis 11, the second king-tower merogenesis 12, the successively from the bottom to top
Three king-tower merogenesis 13 and the 4th king-tower merogenesis 14, steel anchor beam from the bottom to top successively include the first steel anchor beam 51, the second steel anchor beam 52,
Third steel anchor beam 53, the 4th steel anchor beam 54, the 5th steel anchor beam 55, the 6th steel anchor beam 56, the 7th steel anchor beam 57 and the 8th steel anchor beam
58。
Since the second king-tower merogenesis includes third steel anchor beam and the 4th steel anchor beam, between each two corbel, construction space is excessively
Narrow and steel anchor beam is close on the inside of the second king-tower merogenesis, it is impossible to row installation again after fractionation.Carrying out steel anchor beam installation in king-tower
When construction, if determining king-post merogenesis according to the position of steel anchor beam installation, cause king-post merogenesis more, to increase king-post master
The number of turnover of muscle connector, prestress steel twist wire terminal and the inside and outside template of king-post, inherent quality to king-post tower column structure and
Presentation quality has certain influence.
Below in conjunction with the method that Fig. 1 and Fig. 2 illustrate to construct using above-described embodiment construction system, step 1, installation the
Pre-embedded steel slab on two king-tower merogenesis lower part joists, pre-embedded steel slab pass through WELDING STUDS and corbel reinforcement welding；Step 2, by second
King-tower merogenesis top joist influences, and third steel anchor beam, the 4th steel anchor beam cannot be installed simultaneously, before concreting and need to pour
It installs respectively afterwards.The steel anchor beam installed before concreting will influence the construction of king-tower internal model herein after installation, be supported from internal model
From the aspect of reinforcing, traditional wooden model cannot be used to construct, therefore the part between third steel anchor beam, the 4th steel anchor beam uses tower
Column steel inner template.It is noted that the normal inside and outside mould of king-tower situation template is all made of wooden model, fixed with split bolt；Step 3, by
Concreting is not carried out also in the corresponding lower part joist of third steel anchor beam, therefore third steel anchor beam needs to utilize steel anchor beam interim
Holder is fixed temporarily.Then remaining king-tower reinforcing bar, template and concrete construction are carried out successively, wait for that concrete strength reaches
To the 4th steel anchor beam of installation when design strength, and remove the steel anchor beam falsework below third steel anchor beam.The utility model is applied
Work system, which can be realized, is fused to steel anchor beam installation in king-tower structure construction, reduces the merogenesis construction times of king-tower,
It is not only more advantageous to the inherent quality and presentation quality of control king-tower structure, construction period is more shortened, greatly reduces material
Waste.
In a kind of Cable stayed Bridge Main Tower of specific embodiment and the construction system of steel anchor beam, as shown in Figure 5 and Figure 6, steel anchor
The rectangular top frame 81 that beam falsework 8 is welded including the use of channel steel, with upper frame corner position standpipe 82 connected vertically, and weldering
The reinforced pipe 83 being connected between adjacent standpipe 82.
Each technical characteristic of above-mentioned disclosure is not limited to disclosed and other feature combination, and those skilled in the art are also
Other combinations between each technical characteristic can be carried out according to the purpose of invention, be subject to the purpose for realizing the utility model.
