Abstract
The utility model discloses a purlin is enclosed to annular, including that at least three -section is convex reinforced concrete purlin, all being provided with closure portion at the both ends of reinforced concrete purlin, the reinforced concrete purlin passes through the interconnect of closure portion, the utility model discloses when using, according to the earlier prefabricated good reinforced concrete purlin of designing requirement, then install the bracket in cofferdam with the reinforced concrete purlin appropriate the time on to assemble into the complete purlin that encloses, then descend the process one, owing to adopted the prefabrication system, can carry out multiple quality testing to enclosing the purlin, make the quality of enclosing the purlin obtain the assurance to quality for whole engineering provides the assurance. Owing to make the reinforced concrete purlin according to the designing requirement in advance, when carrying out the underground works construction, can directly install the purlin that encloses that completes on the bracket, shortened the time that the purlin is enclosed in the preparation by a wide margin to the construction period of engineering has been shortened effectively.
Description
Technical field
Enclose purlin when the utility model relates to a kind of architecture construction, be specifically related to a kind of annular and enclose purlin.
Background technology
When circular deep foundation ditch is gone along with sb. to guard him, conventional method adopts annular to enclose purlin as support system, and current Normal practice is, scene steel concrete makes and encloses purlin, the purlin that encloses adopting this method to make has the advantages such as intensity is high, shape is easy to control, reliable in quality, widely applies in bracing engineering; Its shortcoming is: Production Time is long, maintenance slow, from great, costly, make the construction period of engineering longer, can not adapt to the requirement of current people to the high-efficiency high-quality of engineering, enclose purlin according to structure steel fabrication, then support system needs segmentation welding assembly, efficiency of construction improves, but the distortion of enclosing purlin is comparatively large, can cause harmful effect to the quality of building.
Utility model content
For solving the problem, the utility model proposes a kind of annular and enclosing purlin, this encloses purlin and can, under the prerequisite ensureing workmanship, effectively be avoided enclosing purlin and the problem that causes the construction period of engineering longer owing to making.
Concrete technical scheme is as follows:
A kind of annular encloses purlin, and comprise at least three sections of steel concrete purlins in circular arc, be provided with locking part at the two ends of steel concrete purlin, steel concrete purlin is interconnected by locking part.
The utility model in use, is according to designing requirement first prefabricated steel concrete purlin, is then installed on the bracket in cofferdam by steel concrete purlin in due course, and is assembled into and complete encloses purlin, then carries out next process; Owing to have employed prefabrication system, multiple quality examination can be carried out to enclosing purlin, the quality of enclosing purlin is guaranteed, thus provide guarantee for the quality of whole engineering.Owing to steel concrete purlin being made according to designing requirement in advance, when carrying out underground engineering construction, can directly the purlin that encloses completed be arranged on bracket, shorten the time making and enclose purlin significantly, thus effectively shorten the construction period of engineering.
Employing the utility model, can also carry out standardization and purlin is enclosed in mass production, when there being client to need, can directly purchase in Wei Lin manufacturing enterprise, is conducive to dividing the work refinement, and the raising of product quality and production efficiency.
Further, for the ease of controlling the quality of steel concrete purlin, the convenience simultaneously also in order to process and transport, the rise of steel concrete purlin is maximum is good with two meters; The section of steel concrete purlin is rectangular.
The locking part of steel concrete purlin, under the prerequisite of ensuring the quality of products, not only will be conducive to installing, also will conveniently make, and therefore locking part can female tenon and the male tenon that matches with female tenon, or adopts stairstepping joint, also can adopt at steel built-in fitting.When adopting steel built-in fitting, preferably at the external coating anticorrosive paint of steel built-in fitting.
In order to the intensity making annular enclose purlin is guaranteed further, when assembled annular encloses purlin, pea gravel concreten can be built at locking part.

Detailed description of the invention
Consult Fig. 1, a kind of annular encloses purlin, and it is made up of the steel concrete purlin 1 that three sections is circular arc, and be provided with locking part at the two ends of steel concrete purlin, steel concrete purlin 1 is interconnected by locking part.
The utility model in use, is according to designing requirement first prefabricated steel concrete purlin, is then installed to by steel concrete purlin on the bracket in cofferdam 2, and is assembled into and complete encloses purlin, then carries out next process; Owing to have employed prefabrication system, multiple quality examination can be carried out to enclosing purlin, the quality of enclosing purlin is guaranteed, thus provide guarantee for the quality of whole engineering.Owing to steel concrete purlin being made according to designing requirement in advance, when carrying out underground engineering construction, can directly the purlin that encloses completed be arranged on bracket, shorten the time making and enclose purlin significantly, thus effectively shorten the construction period of engineering.
Employing the utility model, can also carry out standardization and purlin is enclosed in mass production, when there being client to need, can directly purchase in Wei Lin manufacturing enterprise, is conducive to dividing the work refinement, and the raising of product quality and production efficiency.
In the present embodiment, the rise of steel concrete purlin 1 is two meters; The section of steel concrete purlin is rectangular, consults Fig. 2, the dovetails 12 that locking part adopts dovetail groove A11 respectively and matches with dovetail groove A11.
Locking part can also adopt following form respectively: (1), consult Fig. 3, arranges dovetail groove B13-1 and dovetail groove C13-2 respectively, be connected with two dovetails 14 that dovetail groove B13-1 and dovetail groove C13-2 all coordinate at steel concrete purlin 1 two ends.(2), Fig. 4 is consulted, the straight wall block 15 that locking part adopts straight wall groove 16 respectively and matches with straight wall groove 16.
The male tenon that the form of above-mentioned three kinds of locking parts is female tenon and matches with female tenon, certainly also has other tongue and groove form of structure, as long as can meet requirement of the present utility model, all can be used for the utility model.
Locking part can also adopt stairstepping joint, consults Fig. 5, and locking part is individually designed as single step joint A17 and single step joint B18 of matching with single step joint A17; Or consult Fig. 6, locking part is individually designed as Double step shape joint A19 and the Double step shape joint B20 that matches with Double step shape joint A19, and certain locking part also can be designed as the joint of multiple step surface.
Locking part can also adopt the form arranging steel built-in fitting A21 and steel built-in fitting B22 at the two ends of steel concrete purlin 1 respectively.When locking part is steel built-in fitting, preferably at the external coating anticorrosive paint of steel built-in fitting, to reduce acidic materials in earth to the corrosion of steel built-in fitting.Anticorrosive paint can select asphalt varnish, epoxies corrosion resistant coating, chlorinated polyvinyl chloride class corrosion resistant coating or chlorinated rubber class corrosion resistant coating, and anticorrosive paint of the prior art has and a variety ofly can meet the anticorrosion of steel built-in fitting, does not repeat them here.
When assembled the utility model annular encloses purlin, pea gravel concreten can be built at locking part, while the bonding strength strengthening locking part, can also play a protective role to locking part.
