Specific embodiment
Below in conjunction with embodiment the present invention is further specified:
The template system of prefabricated simple supported box beam; Comprise bar shaped beam making bench 1, prefabricated simple supported box beam, end template 2, side template 3, Side Template and inner formword; On the built-in fitting on the bar shaped beam making bench 1, be connected with I-steel; I-steel is provided with end template 2, and end template 2 is to adopt bolt to connect the piecemeal assembly unit to accomplish, and on the two sides of bar shaped beam making bench 1, is provided with side template connection hinge 6; The lower end and the side template connection hinge 6 of side form support adjustable plate 7 are hinged; Side form supports the upper end of adjustable plate 7 and supports the inner hinged of adjustable plate 9 through the two plate connection hinge 8 and the edge of a wing, and the lateral surface of side form support adjustable plate 7 is arranged on the inboard hang plate of external mold truss 5, between the outer heel post bottom of external mold truss 5 and ground, is provided with end jack 11; Support on the outer heel post top of external mold truss 5 and the edge of a wing between the outer end of adjustable plate 9 and be provided with top jack 10; Between the outer heel post of the inboard hang plate of external mold truss 5 and external mold truss 5, be provided with the bridging support, the medial surface that side form supports adjustable plate 7 is provided with the side template 3 of simple supported box beam, on adjustable plate 9 is supported on the edge of a wing, is provided with the edge of a wing template 4 of simple supported box beam; Be provided with the arc transition section in the lower end of side template 3, side template 3 and end template 2 link together through split bolt.
The outboard end of template 4 is provided with pavement and guardrail 12 on the edge of a wing, accomplishes through the assembly unit of double buckle overlap joint between the piece of described side template 3 and the piece.
Each template of end template 2 two ends adopts 12 millimeters steel plates, and mid portion adopts 10 millimeters steel plates, adopts whole plate at direction across bridge.Steel plate directly is welded on the I-steel of I 16, with I-steel as crossbeam directly with bar shaped beam making bench 1 basis on built-in fitting be connected.When internal mold was installed, its supporting leg directly was placed on the base plate, for preventing the local deformation of supporting leg place base plate, adopted channel-section steel to strengthen at internal mold supported hole place.Connection frame between end template adopts 10 millimeters steel plates, and end template adopts 12 millimeters steel plates with the frame that is connected between side template.2 drainage water hole reserved locations are set on base plate, are used to connect internal mold and support.Base plate adopts partitioned mode, 3 meters of every block lengths, and totally 11, on bar shaped beam making bench 1, accomplish assembly unit, firm between piece and the piece with bolted on connection, 33 meters of bed die total lengths.In the preparatory stretching process of case beam, the decrement that Liang Tiyou is certain is so leave the proper compression amount when back-plane design and installation.In the 2 meters scopes in end template two ends roughness control 2 millimeters with interior, diagonal ERROR CONTROL in 2 millimeters, the discrepancy in elevation that beam two Side Template places are 4 is no more than 2 millimeters, the discrepancy in elevation meets code requirement when guaranteeing that a seat board is installed.Structural strength in the two end bearing scopes and rigidity should be able to be born loads such as 1/2nd beam body, construction.Stretching process central sill body has certain camber, so need according to the designing requirement of case beam suitable antiarch value to be set on base plate, antiarch calculates according to the line style of second-degree parabola, being the parabola minimum point in the case girder span.
The gradient of side template and beam height degree can be regulated through the manual jack of external mold truss 5 bottoms, and every side has 32 on 20 tons of jack.Side template adopts 8 millimeters steel plates, and the street crossing on the operating platform adopts 3 millimeters diamond plates.Left and right side frame adopts 12 millimeters steel plates, and support adopts two I-steel to meet the assembly welding structure composition that angle requires.Ribs adopts shaped steel and stiffener to form, and is welded with attached vibrator on the ribs and connects steel plate.On side form, reserve air vent built-in fitting position, apart from 1.9 meters of base plate height.Side template adopts cross rib to join support, and support adopts on-the-spot assembled, and side form two flange plates are provided with platform, and platform is wide 98 millimeters, and guardrail is established on the limit, can bear steam-cured canopy and weight such as rain shade and construction loads.The evener track is set on the platform.Take all factors into consideration transportation and easy for installation, outboard template adopts the mother-son mouth overlap joint in the horizontal, can prevent spillage, easy operating.2 meter one Pin of external mold truss is provided with bridging in the rear pillar vertical rod, and horizontal support up and down is set, and in order to strengthen the globality of template, prevents to cause in the concrete placement template deformation.Adopt the structural form of outboard template folder end template, side template is designed to fixed, and promptly side template is corresponding one by one with end template.Case beam plate outer side arc transition is arranged on the side template, to make things convenient for, to move beam.Side template adopts the bolted while also to adopt with end template pulling plug is connected, and utilizes length and intensity to pulling plug to be fastenedly connected, to pulling plug through support to drawing, and take appropriate reinforcement measure, the assurance globality.The surface of external mold directly influences the presentation quality of case beam, must guarantee template assembly length, seam slit and template surface flatness.The polishing cleaning must be thoroughly after each the use, and the releasing agent brushing will be tried hard to keep evenly, to guarantee the smooth gloss of beam surface.
Side Template is formed by panel, vertical rib and cross rib assembly welding, all adopts Bolt Connection between Side Template and end template and the exterior sheathing.Panel is made up of steel plate, and vertical rib and cross rib adopt the shaped steel assembly welding to form.The end mould structurally is divided into upper and lower two, so that transportation.Side Template adopts end bag side form, and integral body is divided into four: one is base plate, two blocks of webs, a middle part top board, and the end mould is provided with platform and guardrail is installed, and forms a closed circle with the side form guardrail, guarantees workmen's handling safety.
Inner formword is the principal element of decision site operation efficient, and in order to raise labour efficiency, box girder inner formwork adopts all-hydraulic convergent-divergent internal mold, utilizes hydraulic system to accomplish the support and the contraction of internal mold.The internal mold longeron has regulatory function, can guarantee to form the second-degree parabola antiarch line style of regulation.Internal mold adopts on the keel and puts, and keel are welded in the internal mold backform.The internal mold jacking realizes that through outer four jacking cylinders of beam and two interior jacking cylinders of beam lifting distance is 300 millimeters.Inside molding plate divides backform and side form.
