Abstract
The invention relates to a construction method of a beam-slab type reinforced concrete domed chamber structure. The method comprises the following steps: setting out in advance, prefabricating a mold plate and a square wood bar, pre-splicing the mold plate, connecting steel pipes, installing the mold plate, repairing the mold plate and carrying out other working procedures, thereby realizing concrete pouring of the domed chamber structure finally. Sleeves, the steel pipes and the other materials are used when a framework in an arc-shaped area is set up, and the sleeves and the steel pipes are sequentially abut-jointed, so that a closed hemispherical mold plate system is formed and the implementation of setting up the framework is ensured.
Description
Technical field
The present invention relates to a kind of dome-type beam and slab type steel concrete dome structure construction method.
Background technology
At present, dome structure mostly now is the building of ethnic group's style, belong to typical special-shaped building, the technical data of the existing dome construction aspect of country is incomplete, a kind of complete method is not had to the construction of small beams board-like steel concrete dome roof structure, the beam and slab structure template of dome construction and support are the key of dome construction, directly have influence on concrete construction safety, quality.Adopt common support for shuttering to carry out concrete placings, its molded appearance mass effect is undesirable, therefore needs to adopt special template, and domestic this type of typified form of template manufacturer production that there is no, special processing template, material cost will be very large.
Summary of the invention
In order to overcome the deficiency that existing falsework is applied at dome structure, the invention provides a kind of new type formwork support erection method.The method adopts steel pin hand support for shuttering and composite board formwork system scheme, runs through support for shuttering and sets up to template, the overall process such as to build construct to reinforcing bar binding, concrete vault.The method can be suitable for dome structure, and implementation result is very good, and building products is quite attractive in appearance, and comprehensive benefit is better.
The technical solution adopted for the present invention to solve the technical problems is: when dome-type dome structure falsework is set up, support bracket adopts conventional fastener formula steel-tube die support, when setting up arc area support for shuttering, select the material such as sleeve, steel pipe, sleeve is utilized to dock with steel pipe order, thus form closed dome-type template system, ensure the exploitativeness of support for shuttering.First on smooth flooring, amplification sample is carried out according to the size of design before construction, steel pin hand support for shuttering is set up according to amplifying the size of sample, according to stupefied at the bottom of the horizontal stupefied and beam of full-page proof size prefab form level, precast assembly beam forms, horizontal steel tube at the bottom of mounting rail, mounting rail template, installing plate soffit formwork, after whole installation passed examination, with high-strength putty, template seam is carefully scraped benefit to fill and lead up, then segmentation colligation slab muscle, outer unit template is installed in segmentation, last segmentation concreting.
The invention has the beneficial effects as follows: can complete that semi-circular dome structure is concrete builds with flying colors, and achieve recycling for the material setting up template, reduce consumed resource, cost-saving.

Detailed description of the invention
(1) preparation of construction
In FIG, carry out template construction control line and the setting-out of formwork bearing frame control line by size, tissue engineering technique person, Quality Inspector check and accept vault construction control line.
(2) load-bearing support for shuttering is set up
In the embodiment depicted in figure 2, support for shuttering adopts fastener type steel pipe scaffold, and the fastener of material Φ 48 × 3.5 steel pipe scaffold and correspondence, wall side vertical pole ' s span is not more than 1.5m.Under dome, by-level plate portion vertical pole ' s span is 0.6m.Wall construction is complete, reaches the condition setting up load-bearing support for shuttering, by amplifying sample dimensioned support for shuttering steel pipe and starting to set up load-bearing support for shuttering.
(3) precast beam wooden form
In figure 3, by amplifying the size precast beam wooden form of sample, the bed die of every root beam, side form three face die plate is pre-formed on ground.
(4) horizontal steel tube at the bottom of mounting rail mounting rail template
In embodiment illustrated in fig. 4, before horizontal steel tube at the bottom of mounting rail first by amplify sample comparatively to upper plane absolute altitude and under shelve absolute altitude a little, horizontal steel tube is installed stupefied after errorless again, then puts by-level steel pipe stupefied, install moulding board of precast beam, the gap of adjustment support for shuttering and beam makes the stupefied uniform force of level.
(5) dome bed die level, longitudinal keel are installed
In Figure 5, dome level adopts Φ 48 × 3.5 steel pipe pipe nipple to end keel, radial load is born primarily of bearing frame horizontal steel tube, horizontal steel tube requires to arrange by amplification master drawing length to put in place, horizontal keel is connected with bearing frame horizontal steel tube fastener, longitudinal keel 30 × 50 lumps of wood, adopt 14# galvanized iron wire with fastener for connection.
(6) dome soffit formwork is laid
In Figure 5, because six roots of sensation beam is not decile in domed-face, therefore amplifying sample can not accurate prefab form, by the wood lath that wooden form electric saw becomes 300mm wide, due to employing is outer vertical stupefied, the wide wooden form of 300mm adopts horizontal spelling, with 3 cun of steel nails be fixed on vertical stupefied on, to unify sawing shaping for electric saw by hand.
Claims (1)
1. a dome-type beam and slab type steel concrete dome structure construction, when dome-type dome structure falsework is set up, support bracket adopts conventional fastener formula steel-tube die support, when setting up wall arc area support for shuttering, select the material such as sleeve, steel pipe, realized the arc in template face by the connected mode adjusting horizontal steel tube, it is characterized in that: horizontal steel tube docking at the bottom of beam is linked in sequence by adopting sleeve, Nodes is without the need to adopting fastener to connect or welding.
