Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Referring to Fig. 1, and combine shown in Fig. 2, Fig. 3 and Fig. 4, the present invention provides a kind of solid pier capping beams to process construction party
Method, comprising the following steps:
Step S1 installs punching rod iron 10, and utilize punching in the pre-buried pvc pipe in the top of Thin-Wall Piers in the pvc pipe
Rod iron 10 sets up hanging seat 20；
Step S2 installs triangle support bracket 40 based on the hanging seat 20, the installing point on the triangle support bracket 40
With beam and bracket；
Step S3 lifts by crane installation bed die, the structure based on Thin-Wall Piers, to arrange bed die mounting process using crane；
Step S4 installs side template based on the end template, constructs safeguard structure, carry out pouring concrete and maintenance.
A kind of solid pier capping beam of the invention processes construction method, by using pre-buried pvc pipe, at the top of Thin-Wall Piers
One through-hole for running through Thin-Wall Piers is set, punching rod iron 10 is passed through into pvc pipe, sets up triangle load-bearing at the both ends of punching rod iron 10
Bracket 40 is formed using triangle support bracket 40 and is supported, and installs distribution beam and bracket sets up low mould and side template, poured
Concrete, to form solid pier capping beam.
A kind of solid pier capping beam of the invention processes construction method, and construction technology is simpler, with traditional construction method
It compares, construction technology is simpler, and repeatability is strong, is conducive to operating personnel and skillfully grasps；Component needed for short construction period
The factorial production, quality are easy to guarantee.
In order to guarantee that triangle bearing frame is harmonious to the active force of Thin-Wall Piers, the plan-position deviation of pvc pipe of the invention
Less than or equal to 5mm, and the height error of pvc pipe is less than or equal to 5mm, thus the levelness to guarantee pvc pipe.
In order to further ensure that deviation does not occur in casting process for pvc pipe, i.e., for installing punching in guarantee Thin-Wall Piers
The active force of rod iron 10 is harmonious, and the pre-buried spacer bar by Thin-Wall Piers of pvc pipe of the invention is to position, and spacer bar
It is welded in the pier shaft main reinforcement of Thin-Wall Piers, as shown in Figure 2.
In a preferred embodiment of the invention, the both ends of punching rod iron 10 of the invention are equipped with coarse thread, and punching steel
The both ends of stick 10 pass through the hanging seat 20 and by nut 30 with fixation.
And in order to guarantee the stability of triangle support bracket 40, triangle support bracket 40 is by two panels triangle skeleton by two panels
Triangle skeleton is welded to form an entirety by transverse beam, and wherein monolithic triangular shape skeleton is welded by fashioned iron.And
And dismantle for convenience, outrigger 41 is welded on triangle support bracket, and the length of outrigger 41 is than the lid of the Thin-Wall Piers
Beam width is big.
That is two panels triangle skeleton clear span is 5cm wider than Thin-Wall Piers pier shaft, concentrates at front end " 7 font " for stress
Position carries out patch weldering using steel plate to guarantee the safety of steel construction, so that 40 firm welding of triangle support bracket.
Triangle skeleton is installed using crane, " 7 font " suspended end is hung on innovation rod iron hanging seat 20, the support of lower part
Beam is fitted in Thin-Wall Piers, and pier shaft provides reaction of bearing, and suspended end is fitted closely with wall built-up needs, therefore uses steel plate to the two
Between gap fill up.
Further, the invention also includes following steps S5, after the intensity that step S4 pours concrete reaches 2.5Mpa, carry out
