Abstract
The utility model relates to a combined arch crown for building arch buildings. In a groove of a central connection disc, five supporting rods with equal included angles are fixed in a radial form. The outer end of the supporting rod is fixed with a sector formed by a diagonal connection rod, and two supporting rods below the sector use a through rod to form a horizontal supporting rod. Two ends of the horizontal supporting rod and the middle part thereof are provided with support columns to cause the sector to be vertically arranged on the support columns. A plurality of vertical sectors with proper space are connected to form a skeleton via a transverse connection rod, and the diagonal connection rod thereof is provided with a mould plate. The mould plate is provided with adjustable materials which are adjusted to form an arch construction surface, and then the combined arch crown can be formed. The position between each supporting rod and the connection rod is connected via a pipe fastener. The utility model has the advantages of convenient disassembly, convenient reassembly, repeated use, labor saving, and material resources saving.
Description
The utility model relates to a kind of device that arcuated construction is used of building, and especially can assemble the Combined arch crown that uses repeatedly arbitrarily.
In highway etc. is built, build the arch culvert arch bridge or other arcuated constructions run into through regular meeting.The work of wherein building arch ring is that quite strictness also is suitable trouble, and the making that arch ring supports is the difficult problem in the construction always, and what have encircles tire with clay ox, and what have uses the hophornbeam support, and workload is all quite big, and after using once, has just destroyed, and wastes very big.
The purpose of this utility model is will provide a kind of can make up arbitrarily, and the arch helmet of Shi Yonging is repeatedly avoided and cut the waste.
The purpose of this utility model is achieved in that the semicircle steel plate that has arc band groove to two, groove gets up to recesses coincide, with bolton together, the organization center tie-plate, five support bars are in the radial arc groove that is fixed on the center tie-plate by the center of circle, and each support bar (together with each road arc groove) angle is all 45 degree mutually.Then oblique coupling bar is fixed on the support bar outer end and forms covering of the fan.Two support bars of covering of the fan bottom form horizontal support bar with a through rod on same horizontal linear.At the two ends of horizontal support bar and the middle part pillar that stands on ground or other the firm faces is set, covering of the fan is stood on it.Several (minimum more than two) so are set make its spacing suitably (general about 2 meters), be associated in together, form and stablize skeleton with horizontal coupling bar.On oblique coupling bar, place support shuttering (chaste tree bat, plank etc.) then, on put the arch working face and adjust a layer material (soil, slag etc.) and be adjusted to fairing arch working face and promptly form Combined arch crown.
Since adopt above scheme, the Combined arch crown easy accessibility, and striding footpath and arch camber can change arbitrarily, for reducing engineering quantity, reduces labor intensity, and raises labour productivity, saves material, reduces construction costs and all be significant.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, be the front view among the utility model embodiment
Fig. 2, be that A among the utility model embodiment is to view
Fig. 3, be the steel plate constructional drawing of the semicircle band arc groove of critical piece of the present utility model arch helmet center tie-plate.
Among the figure: 1. pillar; 2. encircle helmet center tie-plate; 3. pipe thread; 4. horizontal support bar; 5. horizontal coupling bar; 6. the arch working face is adjusted layer; 7. support shuttering (Jing Bai etc.); 8. oblique coupling bar; 9. support bar; 10. bolt; 11. semicircle band arc groove steel plate.
As depicted in figs. 1 and 2, two blocks of semicircle steel plates (11) that have arc groove, groove encircles helmet center tie-plate (2) to recesses coincide and with the fastening composition of bolt (10).Horizontal support bar (4) and support bar (9) are in the radial arc groove that is fixed on center tie-plate (2) by the center of circle, and each support bar angle equates.Oblique coupling bar (8) is fixed on the outer end of support bar (4), (9) with pipe thread (3), forms covering of the fan.At the two ends of horizontal support bar (4) and the middle part be provided with and stand upright on ground pillar (1), covering of the fan is stood on it, so, several (more than at least two) are set, make its spacing suitably (being generally about 2 meters), use horizontal coupling bar (5) they to be linked together promptly to form again and stablize skeleton by pipe thread (3).Go up to place support shuttering (7) at oblique coupling bar (8), on put the arch working face and adjust layer (6) (earth, a slag etc.), be adjusted to the arch working face of fairing, can carry out the construction operation of arch ring.
Each support bar, coupling bar, the pipe thread of wherein forming skeleton all adopt φ 50cm building scaffold with steel pipe and pipe thread, can change length arbitrarily, thereby but make span of arch footpath and arch camber random variation.Each coupling bar quantity length, also visual concrete condition changes, and can use more than three such as the horizontal coupling bar (5) that is fixed on the horizontal support (4), in a word with convenient construction with guarantee that workmanship and construction safety are as the criterion.
When an engineering or one section arch ring end, can be for convenience detach, time spent can re-assembly again, so, just can build the arcuated construction that needs, and disassembly and assembly arbitrarily, reduce engineering quantity, alleviated labour intensity, improved labor productivity, save raw material, reduced construction costs.And it is safe and reliable.
Fig. 3 represents that the semicircle of the utility model critical piece arch helmet center tie-plate has the structure of the steel plate (11) of arc groove.By two block plates, can form arch helmet center tie-plate (2) with bolton together, its arc groove is radial by the center of circle, and angle equates to be 45 degree.
Claims (3)
1, a kind ofly build Combined arch crown that arcuated construction uses and make skeleton with steel pipe and form, it is characterized in that: it is to fix five to be the radial support bars that wait angle in the groove of center tie-plate, and the support bar outer end is fixed with oblique connecting rod and forms covering of the fan; Two support bars, one through rod of covering of the fan bottom, form horizontal support bar, two ends and middle part are provided with pillar, covering of the fan is stood on it, the covering of the fan that stands of several suitable spacings is linked together the formation skeleton by the transverse splicing bar, places template on its oblique connecting rod, puts the adjustment material on the template, be adjusted to the arch working face and form Combined arch crown, more than connection between each support bar, coupling bar all use pipe thread.
2, according to the described Combined arch crown of claim 1, its feature also be to form skeleton each support bar, coupling bar, pipe thread, all adopt Φ 50cm building scaffold with steel pipe and pipe thread, can change length arbitrarily.
3, according to the described Combined arch crown of claim 1, its feature is that also the center tie-plate is the steel plate that is had arc groove by two and half garden shapes, forms with bolton together, and its groove is radial by the center of circle, and angle equates to be 45 degree.
