Abstract
The invention discloses Precast T-Beam channel steel base construction methods, belong to the beam prefabricated construction fields of T；It is a kind of by the use of channel steel as Precast T-Beam pedestal the technical problem to be solved is that providing, it can recycle, branch is torn open conveniently, is accelerated construction progress, is not generated the channel steel base construction method of building waste；Solve the technical solution that the technical problem uses for：Multi-layer groove steel is laid with after basement process on ground, steel plate is laid at the top of channel steel, branch is torn open conveniently, and reusable edible does not generate building waste；It the composite can be widely applied to the beam prefabricated construction fields of T.
Description
Technical field
Precast T-Beam channel steel base construction method of the present invention belongs to the beam prefabricated technical field of construction of T.
Background technology
With the continuous development of highway construction, the increasingly raising of road and bridge construction technology, Large-span Precast bridge obtains extensively
Using since Precast T-Beam structure has the features such as making is relatively easy, serial pre-fabrication low cost, in large bridge city more
It is common, existing Precast T-Beam pedestal is generally adopted by cement concrete pedestal, can not recycle, and can not dismantle, not be inconsistent
Cyclization guaranteed request can generate building waste.
The content of the invention
It, can be with the invention overcomes the deficiencies of the prior art, and provides a kind of by the use of channel steel as Precast T-Beam pedestal
It recycles, branch is torn open conveniently, is accelerated construction progress, is not generated the channel steel base construction method of building waste.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Precast T-Beam channel steel base construction method,
Include the following steps：
A, basement process：Smooth, compacting is carried out to ground, cure process is carried out to ground；
B, channel steel is laid with：More foundation seat slot steel are longitudinally laid on ground after cure process, in the pedestal channel steel being longitudinally laid with
Top is laterally laid with more support channel steels；
Automatic spraying device is installed c,：Automatic spraying device is installed on pedestal channel steel；
D, steel plate is laid with：More top channel steels are longitudinally laid with above support channel steel, steel plate is laid with above the channel steel of top.
The Land leveling, compacting, compacting degree are at least up to more than 96%, and the hardened ground is handled and mixed using C20
Solidifying soil carries out hardening 10cm leveling layers, and hardening length is T beam lengths, and hardening width is more each wide 5cm than T beam bottom width both sides.
The pedestal channel steel trade mark is 18#, and the support channel steel trade mark is 10#, and the top channel steel trade mark is 5#, the pedestal
Channel steel quantity be 4, spacing 15cm, the support channel steel length be 50cm, spacing 40cm, the top channel steel quantity
For 4, spacing 15cm, the support channel steel is 15cm being provided at both ends with encrypted section, encryption spacing.
The steel plate thickness is 5mm, and steel plate length is T beam lengths, and width is T beam bottom width.
The support channel steel is internally provided with round rubber pipe.
Connection mode between the pedestal channel steel and support channel steel is welding, the support channel steel and top channel steel
Between connection mode for welding, connection mode between the top channel steel and steel plate is welding.
The automatic spraying device includes controller, channel steel base sprinkling equipment, and controller is set with channel steel base spray
It is standby to be connected.
The present invention has the advantages that compared with prior art.
1st, using channel steel base, the processes such as concrete formwork is not required, pours, simplifying Precast T-Beam pedestal construction technology,
The construction time is shortened, reduces construction cost, while automatic spraying device is provided on pedestal channel steel, unlike concrete bottom
It is during seat construction that water pipe is pre-buried in the base, simplify difficulty and the construction time of construction.
2nd, using channel steel base, branch tears open conveniently, will not generate building waste, be conducive to protect surrounding enviroment, produces
Good social benefit is given birth to.
3rd, Precast T-Beam pedestal is constructed using channel steel, compared with concrete bed, is ensureing the same of precast beam construction quality
When can also save construction cost, significantly increase economic efficiency.
Specific embodiment
Precast T-Beam channel steel base construction method of the present invention, includes the following steps：
A, basement process：Smooth, compacting is first carried out to ground, compactness will at least reach more than 96%, ensure holding needed for pedestal
Power is carried, ensures that setting of ground does not occur during T is beam prefabricated, and carries out hardening 10cm thickness leveling layer using C20 concrete and carry out
Cure process, hardening length are the length of T beams, and hardening width is more each wide 5cm than T beam bottom width both sides.
B, channel steel is laid with：On the leveling layer hardened, longitudinal direction is laid with 4 18# pedestal channel steels, and channel steel length is T beam lengths
Degree, if channel steel length can not enough carry out spreading with the mode of welding, the spacing between pedestal channel steel is 15cm, in pedestal channel steel
The upper 10# support channel steels for being laterally laid with 50cm long, spacing 40cm are encrypted at the both ends of T beams, and encryption spacing is 15cm,
Round rubber pipe is set inside support channel steel, prevents that spillage generates flash phenomenon, pedestal channel steel and top when T beams from pouring
It is connected between channel steel by the way of welding.
Automatic spraying device is installed c,：Automatic spraying device is installed on pedestal channel steel, longitudinal direction is set in pedestal channel steel
Water pipe sets 14 spray heads on longitudinal water pipe, and spray head is horizontally installed among support channel steel, wherein 10 spray heads are big
Angle automatic shower nozzle, face T beam diaphragm plates ensure the maintenance of T beam beams body, wherein 4 are fixed showerhead, wherein 2 sprays
Head connects T beams top spray head by hose, ensures top maintenance, in addition 2 spray heads are located at T beam ends, prevent to spray blind
Area.
D, steel plate is laid with：4 top channel steels, trade mark 5#, top channel steel and support are longitudinally laid with above support channel steel
Connection Ei modes between channel steel are welding, and the steel plate of 5mm is set on top channel steel upper berth, and steel plate length is T beam lengths, and steel plate is wide
It spends for T beam bottom width, is connected between top channel steel and steel plate by the way of welding, steel plate passes through grinding process, ensures rigidity, flat
Whole degree, finish etc. meet construction process requirement, and steel plate brushes oily wax after grinding process, ensures T beam beams bottom presentation quality.
