Abstract
The utility mode relates to a bow -shaped steel pipe back up support has solved current template and has strutted the problem that has the big just installation back adjustment of longer, the safe degree of difficulty consuming time and waste time and energy. The support body that distributes around a plurality of pin, every support body includes vault back up and arch wall back up, vault back up and the tangent concatenation of arch wall back up, and the arch wall back up supports on interim inverted arch, the vault back up comprises the back up body that two sections length are different, and two sections back up bodies staggered arrangement in each pin support body, constituteing by at least two sections back up body I of arch wall back up, between vault back up and the interim inverted arch, all prop up between the two arch wall back ups and be equipped with the support steel pipe of connecting through steel tubes clamps. The utility model discloses not only having shortened the scattered mould of two linings and having strutted the time, improved the efficiency of construction, improved the reinforced (rfd) quality of two lining templates moreover effectively, saved a large amount of manpower and materials simultaneously, the cost reduces by a wide margin.
Description
Technical field
The utility model relates to the loose mould suspension device of construction two lining, is specially a kind of arc steel pipe back up support.
Background technology
Tunnel double-lining construction in, template support be two linings construction extremely important be also a very crucial procedure, template support quality directly has influence on concreting safe mass, finally has influence on the quality of whole constructing tunnel.
Conventional template supporting generally adopts the way of i iron bow member supporting, and the method is consuming time longer, and fabrication and installation difficulty is comparatively large, and after installing, adjustment often needs waste for a long time.
Summary of the invention
To there is longer, safe difficulty consuming time large and install and adjust the problem wasted time and energy afterwards in order to solve existing template support for the utility model, provides a kind of arc steel pipe back up support.
The utility model adopts following technical scheme to realize: arc steel pipe back up support, comprise the rack body distributed before and after some Pin, each rack body comprises the vault back up that coordinates with vault inner arc wall and is positioned at the vault back up left and right sides and the arch wall back up coordinated with arch wall inner arc wall, vault back up and the tangent splicing of arch wall back up, and arch wall back up is supported on Temporary invert, vault back up is made up of the back up body that two joint length are different, and two joint back up bodies interlaced arrangement in each Pin rack body, being made up of at least two joint back up body I of arch wall back up, between vault back up and Temporary invert, the supporting steel pipe connected by steel tube fastener is all installed between two arch wall back ups.
When carrying out back up installation exercise, cleaning basal plane, after substantially levelling, starts to set up arch wall scaffold, according to surveying and locating point, determines arch wall back up backing positions and fixes, assembled steel form, can carry out arch wall and build after reinforcing end-blocking; Vertically set up scaffold, 12 × 12cm lumps of wood is utilized to set up platform, fixing vault back up, assembled steel form, can carry out vault concreting after end-blocking, two joint back up body interlaced arrangement of vault back up, make the assembled seam of bow member not point-blank simultaneously, ensure that the resistance to overturning of bow member, overcoming existing template support, to there is longer, safe difficulty consuming time large and install and adjust the problem wasted time and energy afterwards.
The utility model reasonable in design is reliable, not only shortens two linings and to fall apart mould support time, improve efficiency of construction, and effectively improve the quality of two lining formwork reinforcements, save a large amount of manpower and materials, cost significantly reduces simultaneously, has the advantage that structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-vault back up, 2-arch wall back up, 3-Temporary invert, 4-back up body I, 5-supporting steel pipe.
Detailed description of the invention
Arc steel pipe back up support, comprise the rack body distributed before and after some Pin, each rack body comprises the vault back up 1 that coordinates with vault inner arc wall and is positioned at vault back up 1 left and right sides and the arch wall back up 2 coordinated with arch wall inner arc wall, vault back up 1 and the tangent splicing of arch wall back up 2, and arch wall back up 2 is supported on Temporary invert 3, vault back up 1 is made up of the back up body that two joint length are different, and two joint back up bodies interlaced arrangement in each Pin rack body, being made up of at least two joint back up body I4 of arch wall back up 2, between vault back up 1 and Temporary invert 3, the supporting steel pipe 5 connected by steel tube fastener is all installed between two arch wall back ups 2.
In specific implementation process, bottom arch wall back up 2 and between Temporary invert, be provided with adjustment bottom bracing, be convenient to control the template radian between back up body I; Examination should be carried out before using spell, ensure the accuracy of arc steel pipe back up support entirety; Arc steel pipe back up support integral installation is carried out template compound, is guaranteed two lining concrete surface non-intrusion edge of workplace after reinforcing; During stripping, from one end, first tear back up open, then form removal, the back up classification after using is put well, uses in order to next time again.
