Abstract

The invention discloses an expansion restraint construction method for a post-pouring belt, which can guarantee the structure of the post-pouring belt to be safe and dense, thus achieving the effect of leakage prevention and moisture prevention. The invention comprises the following steps of: 1) installing a post-pouring belt template (1); 2) retaining the post-pouring belt; 3) dismounting the post-pouring belt template (1); 4) pouring the post-pouring belt. In the installation step of the post-pouring belt template (1), a plurality of triangular horizontal strips are pinned on the template (1). Restriction steps are following the step of pouring the post-pouring belt: a steel template (9) is covered on post-pouring belt concrete, and a counter weight (15) is pressed on the steel template (9); or a horizontal steel pipe (6) is installed on a support vertical rod (5) of the post-pouring belt and is provided with a vertical steel pipe (7) which props and presses on the steel template (9) on the post-pouring belt concrete through an adjustable top thread (10).

Description

Ater-casting Constrained expansion construction method
Technical field
The present invention relates to construction techniques, be specifically related to the construction method of ater-casting in monolithic reinforced concrete structure.
Background technology
The construction of ater-casting, have considerable influence to the safe handling of building structure and life-span, existing construction method has following defect: ater-casting place steel gauze formwork, concreting leakiness; It is improper that front method for cleaning is built in ater-casting, forms slag inclusion; Expansive concrete does not have restriction after building, the free wxpansion of concrete upward opening end, and level, to leakiness, becomes defective effect structural life-time; Waterproof, seepage control protection against the tide is not played should have effect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ater-casting Constrained expansion construction method, and it can guarantee that late poured band structure is safe, closely knit, reaches the effect of antiseepage protection against the tide.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of ater-casting Constrained expansion construction technology, comprise the steps: 1) alter-pouring strips mould plate installation, 2) indwelling ater-casting, 3) alter-pouring strips mould plate is removed, 4) build ater-casting, water in the rear in band model sheetinstallat step, described template is followed closely multiple tracks triangle horizontal stripe; Restricted constraint step is also had: on the concrete of ater-casting, cover steel form, on steel form, press counterweight described building after the step of ater-casting; Or install horizontal steel tube in late poured band support vertical rod, described horizontal steel tube arranges vertical steel pipe, described vertical steel pipe withstands the steel form be pressed in above the concrete of ater-casting by adjustable jackscrew.
The invention has the beneficial effects as follows, alter-pouring strips mould plate is followed closely multiple tracks triangle horizontal stripe, the area of the tide that blocks water can be increased; Restricted constraint step allows expansive concrete expand to horizontal direction, and the concrete vertical expansion of confined expansion, guarantees that late poured band structure is safe, closely knit, reach the effect of antiseepage protection against the tide.
Accompanying drawing explanation
Fig. 1 is alter-pouring strips mould plate schematic diagram, and Fig. 2 is raft board post poured band schematic diagram, and Fig. 3 is top board ater-casting schematic diagram.
In figure: alter-pouring strips mould plate 1 triangle horizontal stripe 2 raft plate 3 raft board post poured band 4 late poured band support vertical rod 5 horizontal steel tube 6 vertical steel pipe 7 fastener 8 steel form 9 adjustable jackscrew 10 support level bar 11 top board 12 back timber 13 top board ater-casting 14 counterweight 15
Detailed description of the invention
The present invention includes following steps:
1) alter-pouring strips mould plate 1 installs employing groove joint raft plate 3 thickness being more than or equal to 800mm, groove size is according to 300+200+300mm or each 1/3rd, groove depth is 300mm, multiple tracks triangle horizontal stripe 2 followed closely by the nail in template 1 that should adopt raft plate 3 thickness being less than to 800mm, as shown in Figure 1.
2) vibration compacting is wanted near ater-casting place concrete in indwelling ater-casting.
3) remove alter-pouring strips mould plate 1 to remove when concrete strength reaches design load 30%.
4) ater-casting place concrete curing maintenance 14 days, should be covered between curing time, prevented immersion or foreign material from falling into.
5) clear up ater-casting and first clear up water in ater-casting and foreign material, then rinse earth, concrete bits with giant, then wire brushing reinforcing bar element slurry and corrosion.
6) build UEA in the concrete of ater-casting and, with 10 ~ 12% admixtures of cement consumption, notice that concrete will want vibration compacting.
7) restricted constraining on the concrete of top board ater-casting 14 covers steel form 9, presses counterweight 15, as shown in Figure 3 on steel form 9; Raft board post poured band 4 supported rod erecting 5 installs horizontal steel tube 6, described horizontal steel tube 6 arranges vertical steel pipe 7, described vertical steel pipe 7 withstands the steel form 9 be pressed in above the concrete of ater-casting by adjustable jackscrew 10, as shown in Figure 2.

Claims (1)

1. an ater-casting Constrained expansion construction method, comprise the steps: 1) alter-pouring strips mould plate (1) installation, 2) indwelling ater-casting, 3) alter-pouring strips mould plate (1) is removed, 4) ater-casting is built, it is characterized in that, water in band template (1) installation steps in the rear, described template (1) upper nail multiple tracks triangle horizontal stripe (2); Restricted constraint step is also had: on the concrete of ater-casting, cover steel form (9), on steel form (9), press counterweight (15) described building after the step of ater-casting; Or horizontal steel tube (6) is installed in late poured band support vertical rod (5), described horizontal steel tube (6) is arranged vertical steel pipe (7), described vertical steel pipe (7) withstands the steel form (9) be pressed in above the concrete of ater-casting by adjustable jackscrew (10).
