Abstract
A formwork for pouring arched concrete precast beam slabs comprises an inner arched formwork body and an outer arched formwork body, truss type surrounding purlins are arranged on the inner side of the inner arched formwork body, a plurality of steel pipe surrounding purlins are arranged on the outer side of the outer arched formwork body, and a plurality of tension bars are connected and fixed with the truss type surrounding purlins and the steel pipe surrounding purlins after penetrating through the inner arched formwork body and the outer arched formwork body. The arc-shaped truss type surrounding purlins are installed on the back of the arc-shaped formwork to form the precast beam slab formwork which is stable in whole structure, therefore, the concrete quality defects of dislocation, curtaining and poor moulding appearance caused by displacement and deformation of the formwork in the process of pouring concrete are overcome, the appearance requirement for an arc-shaped structure is met, and the difficulty and the input for repairing the surface of the concrete at the later period are reduced.
Description
Technical field
A kind of template be used to building the arched concrete precast beam of the utility model relates to the concrete construction formwork field.
Background technology
In concrete engineering construction, often run into some arches or arcuate structure concrete, as: the gallery in dam, the positions such as crown of tunnel portal, at these positions as adopting the job practices of cast-in-situ concrete, when template frame stands or removes, construction is disturbed large, time is long, and cost has high input, thereby adopts the job practices of precast concrete more.Usually, during prefabricated arch concrete beam (plate), directly using the steel pipe that is processed into arc shape to enclose purlin reinforces the arch template, yet intensity and the less stable of arc-shaped steel circumference of cannon bone purlin, distortion in various degree can occur after using for several times, cause in prefabricated process arc formwork situations such as being out of shape, losing shape to occur, thereby can not guarantee the Forming Quality of precast concrete beam (plate).This not only can cause the building such as gallery, tunnel crown position the defectives such as faulting of slab ends, presentation quality be poor to occur, has also increased workload and the cost that concrete surface repairs and has dropped into.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of template be used to building the arched concrete precast beam, belfast truss type by design encloses fixedly arch template of purlin, intensity and the stability of enclosing purlin have been increased, can bear the concrete lateral pressure load when prefabricated solidifying native beam slab, repeatedly use situations such as still can not deforming, lose shape.Thereby can guarantee the Forming Quality of precast concrete beam slab, and avoid the architecture constructions such as gallery, tunnel crown the mass defects such as faulting of slab ends, appearance poor to occur, be conducive to reduce workload and the cost that concrete surface repairs and drop into.
The technical scheme that the utility model is taked is: a kind of template be used to building the arched concrete precast beam, comprise interior arch template, outer arch template, described interior arch template inboard is provided with truss type and encloses purlin, described outer arch template arranged outside has many steel pipes to enclose purlin, and many tie rods enclose purlin with truss type after passing interior arch template, outer arch template, steel pipe encloses purlin and is connected and fixes.
It is the truss-like steel framework that many curved steel tubes, many waling stripes and the vertical mutual vertical welding of connecting rod form that described truss type encloses purlin, also is welded with oblique drawbar between waling stripe and vertical connecting rod.
The arc shape of described curved steel tube for matching with the arch of interior arch template, described steel pipe enclose the arc shape of purlin for matching with the arch of outer arch template.The two ends of described interior arch template and outer arch template is equipped with the end socket template.
Described interior arch template and outer arch template are drilled with a plurality of tie rods holes, and their sides also are provided with floor.The place suitable for reading of described interior arch template and outer arch template is provided with many limited support bars equally spacedly.
A kind of template be used to building the arched concrete precast beam of the utility model, beneficial effect is as follows:
Be arranged on the arc formwork back side by the belfast truss formula being enclosed purlin; form the precast beam template of monolithic stability structure; thereby avoided in concreting process because of quality defect of concrete such as template are shifted, faulting of slab ends, curtain, the outward appearance moulding of distortion formation are poor; guarantee the arcuate structure appearance requirement, reduced difficulty and input that the later stage concrete surface is repaired.
The belfast truss formula is enclosed purlin part material can utilize the construction waste and scrap, and processing is simple, can repeat turnover and use.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the main TV structure schematic diagram of the utility model device;
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of template be used to building the arched concrete precast beam, comprise interior arch template 1, outer arch template 2, described interior arch template 1 inboard is provided with truss type and encloses purlin 3, described outer arch template 2 arranged outside have many steel pipes to enclose purlin 4, and many tie rods 5 enclose purlin 3 with truss type after passing interior arch template 1, outer arch template 2, steel pipe encloses purlin 4 and is connected and fixes.Tie rod 5 is to pull-up, and two ends are fixed with interior arch template 1, outer arch template 2 respectively.
Described truss type encloses purlin 3 for the truss-like steel framework that many curved steel tubes 31, many waling stripes 32 and the vertical mutual vertical welding of connecting rod 33 form, and also is welded with oblique drawbar 34 between waling stripe 32 and vertical connecting rod 33.The arc shape of described curved steel tube 31 for matching with the arch of interior arch template 1.Described steel pipe encloses the arc shape of purlin 4 for matching with the arch of outer arch template 2.The two ends of described interior arch template 1 and outer arch template 2 is equipped with end socket template 6.Described interior arch template 1 and outer arch template 2 are drilled with a plurality of tie rods holes, and their sides also are provided with floor.The place suitable for reading of described interior arch template 1 and outer arch template 2 is provided with many limited support bars 7 equally spacedly.
The utility model template is installed and used step:
1), first build on the ground one deck leveling concrete 8, the surface of leveling concrete 8 must guarantee good planeness.
2), according to the designing requirement setting-out, the binding structure reinforcing bar.
3) after, the structure reinforcing bars colligation is completed, arch template 1 and outer arch template 2 in first installing, truss type is enclosed purlin 3 again and place on the ground and be close to interior arch template 1, the steel pipe that truss type is enclosed purlin 3 and outer arch template 2 outsides by many tie rods 5 encloses purlin 4 and is connected and fixed, and end socket template 6 is installed at last.
