Description
Technical field
The utility model relates to a kind of template and encloses purlin device, is specially the adjustable belfast truss of a kind of radius and encloses purlin.
Background technology
Arc surface concrete pouring construction often adopts belfast truss to enclose purlin as template, and the common practice is according to concreting arc surface radius, and the supporting arc of custom-made encloses purlin.Different parts concrete cambered surface radius is usually not identical, and the arc that need customize many cover radiuses different encloses purlin.This method one secures arc radius, and truss purposes is restricted and can not forwards arc radius different position use week to; Two are the increase in construction cost drops into.
Summary of the invention
Technical problem to be solved in the utility model is to provide the adjustable belfast truss of a kind of radius and encloses purlin, solution arc encloses purlin and uses because radius fixes limited, and material is difficult to the technical problem of recycling, not only extend the scope of application that belfast truss encloses purlin, and reduce construction cost.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
The adjustable belfast truss of a kind of radius encloses purlin, comprise bow, cross bar and bush connecting rod, two cross bars and the isometric bow of Duo Gen and many groups bush connecting rod different in size are by connecting bolt Connecting groups synthesis belfast truss formula component, described cross bar adopts adjusting screw(rod) to be connected with adjuster, adjustable belfast truss formula component chord length changes arc radius, described bush connecting rod is that socket joint type connects, and adjustable belfast truss formula member height changes arc radius.
Above-mentioned bush connecting rod junction is drilled with multiple equidistant pin hole, adopts U-shaped latch locking, and bush connecting rod two is drilled with bolt hole.
Above-mentioned cross bar one end is drilled with bolt hole, and the other end is fixed with shrouding, and adjusting screw(rod) is embedded in cross bar through shrouding, two cross bars is connected into one.
Inside and outside above-mentioned cross bar, both sides are fixed with multiple bolt ring, and outside bolt ring is connected with support link.
The adjustable belfast truss of a kind of radius that the utility model provides encloses purlin, the adjusting screw(rod) arranged by cross bar and adjuster and bush connecting rod, adjustment belfast truss formula component chord length and height, thus realize changing the arc radius that belfast truss encloses purlin, and setting operation is easy, practicality is high.Be applicable to arc radius and change little different construction part, be particularly suitable for circular arc transition section engineering.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the adjustable belfast truss of a kind of radius encloses purlin, comprise bow 1, cross bar 2 and bush connecting rod 3, two cross bars 2 and the isometric bow 1 of Duo Gen and many groups bush connecting rod 3 different in size by connecting bolt 4 Connecting groups synthesis belfast truss formula component.Two described cross bars 2 adopt adjusting screw(rod) 5 to be connected with adjuster 9, and adjustable belfast truss formula component chord length changes arc radius.Described bush connecting rod 3 is socket joint type connection, and adjustable belfast truss formula member height changes arc radius.
As shown in Figure 3, described bow 1, be preferably made with double angle is bending, two is drilled with bolt hole, and by the limit Partial Resection of angle steel two ends perpendicular to truss, is convenient to rotate.The quantity of bow 1 and radius size are mated mutually with the radius of belfast truss formula component, also can according to the quantity of belfast truss member radius size adjustment bow 1 and radius size.
As shown in Figure 6, Figure 7, described bush connecting rod 3 is that two steel pipe socket joint types connect, and junction is drilled with multiple equidistant pin hole, and bush connecting rod 3 two is drilled with bolt hole.The length of bush connecting rod 3 can lengthen according to the size of belfast truss component arc radius or shorten.As shown in Figure 1 and Figure 2, the length of adjustable many bush connecting rods 3 rod member, to adjust the height that belfast truss encloses purlin, adjusts the U-shaped latch 6 of rear employing in place and locks.
As shown in Fig. 4, Fig. 5, Fig. 8, described cross bar 2 preferably adopts steel pipe, and one end is drilled with bolt hole, and the other end is fixed with shrouding 10, and adjusting screw(rod) 5 is embedded in cross bar 2 through shrouding 10 and two cross bars 2 is connected into one, has two adjusters 9 in the middle part of adjusting screw(rod) 5.Regulate two adjuster 9 adjustable adjusting screw(rod) 5 protruded lengths, to adjust the chord length that belfast truss encloses purlin.The length of cross bar 2 and adjusting screw(rod) 5 can lengthen according to the size of belfast truss component arc radius or shorten.Inside and outside described cross bar 2, both sides are fixed with multiple bolt ring 7, and outside bolt ring 7 is connected with support link 8.This form of structure, makes the utility model can adopt fastener or the support link that is similar to bar structure is connected with other structure.
In using, as indicated with 1, adjusting screw(rod) 5 protruded length is minimum, and two adjusters 9 are drawn close, and when each bush connecting rod 3 length is long, the utility model is in least radius state.As shown in Figure 9, combinationally use organizing device, utilize the support link 8 outside cross bar 2, bolt ring 7 connected to be combined into a structural entity, force structure reasonable benefit/risk by organizing device, peace is torn open very convenient more more.When needing to use the larger construction part of arc radius, pine, except the U-shaped latch 6 on each bush connecting rod 3, adjusts two adjusters 9, when adjusting screw(rod) 5 protruded length is maximum, each bush connecting rod 3 length is in short-term, and as indicated with 2, the utility model is in maximum radius state.As shown in Figure 10, by organize more device combinationally use time, the multiple bolt rings 7 utilizing cross bar 2 to leave, can adopt the framed bent at fastener or support link and middle part to connect into overall force structure, in figure middle part framed bent not shown.
