Abstract
The present invention relates to field of bridge construction, especially plant cast-in-place Box Bridge bridge floor and face side building enclosure erection method, carry out as follows: production sizing punching block: welding supporting member on the type steel skeleton in the outside of sizing punching block；After type steel skeleton installation is in place, the upright bar of guard rail and supporting member are connected with cruciform fastening for falsework；The supporting member of every fixation type steel skeleton is connected with horizontal cross bar；Temporary protection railing is installed in upright bar, then carries out box girder webs；It is inversely removed after the completion of pouring according to erection sequence.The method of the present invention is easy to operate, accelerates the connection of steel pipe and fashioned iron, improves work efficiency and construction precision, and steel pipe and cruciform fastening for falsework can be recycled after the later period removes, and reduce cost.
Description
Technical field
The present invention relates to field of bridge construction, especially a kind of cast-in-place Box Bridge bridge floor faces side building enclosure erection method.
Background technique
With the increasingly standardization of construction, portability, people have the construction method in work progress higher
It is required that.Traditional fashioned iron and steel pipe connection method has been far from satisfying the requirement of construction.During construction of cast-in-situ box-beam, the wing
Template die plate is usually using sizing punching block, and lower to be supported with channel steel frame, bridge temporary protection railing is mounted in channel steel frame.According to
Traditional method, the type of attachment between channel steel frame and channel steel frame, between channel steel frame and bridge temporary protection railing are general
It is connected using bolt system, or welding.This traditional method complex procedures, a large amount of uses, which are bolted, leads to the duration of constructing
Greatly increase, when the later period removes, as bolt deforms, corrode, screw thread is impaired situations such as will be difficult to dismantle, can only be using destroying
Formula dismantling, causes difficulty of construction further to increase, duration lag.
Summary of the invention
In order to solve the above technical problems, the present invention uses a kind of reduction construction personnel's workload, showing for working efficiency is improved
It pours Box Bridge bridge floor and faces side building enclosure erection method.
The present invention adopts the following technical scheme:
A kind of cast-in-place Box Bridge bridge floor faces side building enclosure erection method, carries out as follows:
1) production sizing punching block: supporting member is welded on the type steel skeleton in the outside of sizing punching block；
2) after type steel skeleton installation is in place, the upright bar of guard rail and supporting member are connected with cruciform fastening for falsework；
3) supporting member of every fixation type steel skeleton is connected with horizontal cross bar；
4) temporary protection railing is installed in upright bar, then carries out box girder webs；
5) it is inversely removed after the completion of pouring according to erection sequence.
Compared with prior art, the beneficial effects of the present invention are:
This invention simplifies working procedures, accelerate the progress of installation and dismounting, have saved cost, are reducing construction personnel's work
While amount, construction progress is accelerated, improves working efficiency and construction precision.
Detailed description of the invention
Fig. 1 is effect picture of the invention；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is usage state diagram of the invention；
In figure: sizing punching block 1；Type steel skeleton 2；Supporting member 3；Guard rail upright bar 4；Horizontal cross bar 5；Cruciform fastening for falsework 6.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
A kind of cast-in-place Box Bridge bridge floor faces side building enclosure erection method, carries out as follows:
1) production sizing punching block 1: two diameters of welding are 48mm on the type steel skeleton 2 in the outside of sizing punching block 1, and wall thickness is
3.5mm, length are that the steel pipe of 200mm is as shown in Figure 2 as supporting member 3().
2) after type steel skeleton 2 is installed in place, guard rail upright bar 4 is connect with the cruciform fastening for falsework 6 of supporting member 3.
3) two horizontal cross bars 5 disposed in parallel of the supporting member 3 of every fixation type steel skeleton 2 are connected, fashioned iron
Skeleton 2 is one-piece construction, is equidistantly connected by horizontal cross bar 5, and will be supported by cruciform fastening for falsework 6 and connected with horizontal cross bar 5
Connect (as shown in Figure 1,3).
4) guard rail upright bar 4 is arranged in protective frame upright bar 4 according to one of the every 1.5 ~ 2m of spacing of type steel skeleton 2 setting
Horizontal steel tube installs Dense mesh screen between guard rail column 4 and horizontal steel tube, and guard rail is made to form wide 1.5 ~ 2m, high 1.2m
Extraordinary maintenance structure；Then box girder webs are carried out.
5) it is inversely removed after the completion of pouring according to erection sequence.
Type steel skeleton in the present embodiment is welded by channel steel, and supporting member is welded on the fashioned iron on the outside of sizing punching block
On.
The present embodiment keeps working procedure easier using cruciform fastening for falsework, speed of application faster, and steel pipe and cross buckle
Part can be used in turn, and reduce the cost of construction.
The above is only a specific embodiment of the invention, but are not limited to this to protection of the invention, all this technology necks
Field technique personnel it is thinkable to the technical program technical characteristic propose equivalent change or replacement, all cover in the present invention
Protection scope within.
