Description
Technical field
The utility model belongs to the technical field of arch culvert construction, is specifically related to a kind of arch culvert arch ring steel form carrier.
Background technology
Fast development along with the highway construction of China Higher level, the job practices of arch culvert also begins to diversified development, the main job practices of arch culvert has: column bow member method, support type bow member method, clay ox method etc., but, because the construction and installation of bow member method, striking and shuttering work repeat, workload is big, and construction period is longer, so that above-mentioned job practices also requires further improvement is perfect.
Certain expressway works of undertaking the construction of of applicant for example, the K119+065 culvert, 134.6 meters of total lengths are divided into 22 joints.The center pile No. is: K119+065, oblique 120 degree, form of structure is: 1-3.0m steel bar concrete arch culvert, this culvert is monolithic reinforced-concrete basis, gravity abutment body, semicircular arch ring, and wherein arch ring, arch springing adopt the C30 concrete, and basis, abutment body, cap stone adopt the C25 concrete.Because this culvert is longer, and the duration is very tight, engineering quantity is bigger, therefore select which kind of support and arch template, just seem particularly important.
Bow member method construction disassemble and assemble work amount is bigger, and required construction period is longer, can not satisfy the requirement of on-site actual situations and duration, mainly has following problem:
1, because construction height is higher, the basis is pushed up to the distance of vault and is: 5 meters, every joint arch ring support and template all need be installed, be removed, and it is not easy to operate to construct, and repetitive operation is many, and workload is big, and construction speed is slower, and construction cost is bigger;
2, the arch ring concrete is in work progress, need split into loose mail earlier when installation, striking and template, and be transported to ground, reinstall again, and fall easily pipe fitting or punching block assort, the accident that causes casualties takes place, and big potential safety hazard is arranged;
3, it is wayward that quality is propped up, torn open to the circular arc template of arch ring both sides arch springing part, and produce seam, faulting of slab ends with the abutment body body of wall easily, can not satisfy and construct and code requirement;
4, promptly become waste product after the circular arc assembled formwork of bow member method construction uses up, can not reuse, cause the waste of material, construction cost strengthens;
5, support and template deformation phenomenon easily take place in the construction of bow member method, and the difficult installation of circular arc template, easily cause the concrete external surface height of every joint arch ring inconsistent, and the concrete presentation quality of building is relatively poor, is easy to generate faulting of slab ends and spillage phenomenon.
Summary of the invention
The problem that the utility model is installed repeatedly, removed for the existing arch culvert work progress hogging coil support of solution, template provides a kind of arch culvert arch ring steel form carrier.
The utility model adopts following technical scheme to realize:
Arch culvert arch ring steel form carrier, the mould bases that comprises steel truss structure, mould bases bottom symmetry is installed four steel wheels, the mould bases bottom also is provided with some jack supporting-points, the internal mold and the external mold of circular arc installed at the mould bases top, and internal mold comprises by the vault part of bearing pin connection and the arch springing part of both sides, between internal mold and the external mold pull bar is set, the two ends up and down of pull bar are connected with external mold, internal mold respectively, are connected with leading screw between the arch springing part of internal mold and the mould bases top.The pull bar upper/lower terminal uses taper sealing bolt, the outside butterfly card that uses with the part inside that is connected of external mold, internal mold.
When using, the supporting jack of pallet bottom described in the utility model is regulated the height of mould bases.
The utlity model has following beneficial effect: saved the time of propping up, tearing open support and template repeatedly, significantly reduced working procedure and workload, steel form carrier intensity, rigidity and stability are all fine simultaneously, are difficult for producing distortion; This chassis mould bases is simple in structure, be easy to processing, the surface steel sheet seam is tight, the arc unanimity, and whole adjustability is good, template need not to carry out propping up of repetition and tears operation open after standing well, after a last joint arch ring construction finishes, directly run to down the construction location of joint arch ring, the construction of following joint arch ring, thereby shortened construction period effectively, accelerate construction speed, reduced construction cost, improved economic benefit; After construction was finished, chassis mould bases material was all reusable after disintegrating; The concrete arch astragal type unanimity of constructing, concrete surface is smooth, smooth, so in the construction bigger practical value is arranged at the scene, can large-scale popularization use in similar engineering; Construction speed, safety all are controlled effectively, and the construction demand has all been satisfied in every design preferably.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: 1-steel wheel, 2-jack, 3-mould bases, 4-bearing pin, 5-pull bar, 6-internal mold, 7-external mold, 8-leading screw, 9-taper sealing bolt.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
Arch culvert arch ring steel form carrier, it is characterized in that comprising the mould bases 3 of steel truss structure, mould bases 3 bottoms symmetry is installed four steel wheels 1, mould bases 3 bottoms also are provided with some jack supporting-points, the internal mold 6 and the external mold 7 of circular arc installed at mould bases 3 tops, and internal mold 6 comprises by the vault part of bearing pin 4 connections and the arch springing part of both sides, between internal mold 6 and the external mold 7 pull bar 5 is set, the two ends up and down of pull bar 5 are connected with external mold 7, internal mold 6 respectively, are connected with leading screw 8 between the arch springing part of internal mold 6 and mould bases 3 tops.The pull bar upper/lower terminal uses taper sealing bolt, the outside butterfly card that uses with the part inside that is connected of external mold, internal mold.When using, supporting 6 jack of pallet bottom are regulated the height of bow member.
Below specify each ingredient of the present utility model:
