Description

Novel steel framework wooden form

Technical field

The utility model relates to a kind of novel steel framework wooden form, belongs to the construction formwork field.

Background technology

In the construction works such as modernization large stadium, water conservancy, road, bridge, building, require the concrete project of senior clear water effect more and more, the construction formwork that can satisfy this requirement mainly is a steel framework wood plywood template, is called for short the steel framework wooden model.Mainly contain Germany " PERI " in the world and Austria template companies such as " DOKE " has ripe steel frame plywood technology, main member have "

" to be 100 * 4 square tube be connected jig with 100 * 50 * 3 square type pipe and special-purpose frame for type frame, the empty stomach steel pipe of wall thickness 2mm, rib.Its mould plate technique belongs to no back cord large form series, has realized product seriation and standardization, and mould plate technique is functional, satisfies Deutsche industry norm (DIN) 82.5kN/m ²The requirement of concrete calculation side pressure, international applications is extensive.But weak point one is a frame cross-section structure complexity, rolling difficulty, and tube wall is thinner, and local stiffness and assembly welding intensity are insufficient; The 2nd, whole back side fixed panels, concrete surface forming defectiveness.

In the domestic existing steel framework wooden model technology, frame is generally simple both sides and manages assembly welding or indiscriminately imitate external similar technology substantially, does not form series of products, and the mould plate technique poor-performing exists the problem of frame connection reliability, and substantially all is from the front fixed panel.The applicant development and production in recent years shaped steel frame wooden model technology that makes new advances, frame is assembly welding " R " type, main rib is 100mm * 4mm square tube and rolling 100 * 43 * 25 * 3 (mm) " material, have single hinge wedge pawl frame and connect jig, the template width is template with 300mm, standard size is highly arranged and connect high size, technical performance is good, reach international industry level, successful Application is in the National Stadium, but this steel framework wooden model exists assembly welding " R " type frame manufacturing process complexity, the assembly welding difficulty, main rib kind and master die specification are many, and defectives such as wall piercing bolt complicated layout are demanded system research and improvement urgently.

Summary of the invention

The purpose of this utility model is to overcome the unreasonable problem of existing steel framework wooden form design, provides a kind of simple in structure, and assembly unit is convenient, fast, and the reliable and seam crossing of intensity and stiffness is the novel steel framework wooden form of faulting of slab ends not.

The purpose of this utility model is achieved through the following technical solutions:

Novel steel framework wooden form comprises frame, panel and ribs, and wherein frame is the steel hollow section that the cross section is " R " type, and above-mentioned frame is pressed the normal width specification and formed rectangular frame; Described ribs is the steel hollow section, is arranged between two long margin frames of rectangle, and the cross section of ribs is " C " type, and two rib pin of its " C " type opening part curve inwardly, and the ribs top equates with above-mentioned seal ring thickness to the distance on rib sole plane; Described panel is fastened on frame and " C " type ribs with screw.

" R " type frame is made " R " type hollow section by steel plate cold bending, and its section comprises baseplane, big straight flange, flanging and plane, top; The part that big straight flange grows the plane, top forms inner face, its grow part with joining panel thickness equate that the panel side nestles up this inner face; Flanging is connecting baseplane and plane, top, and panel is fixed on the plane, top; The middle part, baseplane is slightly recessed, and there is arc chord angle both sides.

The end face that the flanging of frame " R " type section forms inwardly forms the scrobicula face near the part of big straight flange.The plane, top of " R " type frame inwardly forms concave surface near the part of big straight flange.

On the flanging of frame " R " type section and the crown center of ribs " C " type section be respectively arranged with screw hole, by screw panel and frame and ribs are fastenedly connected respectively.

The beneficial effects of the utility model are: the strength and stiffness of formwork integral are reliable, features simple structure, quick for installation, seam crossing is faulting of slab ends not, engage closely, be difficult for spillage, can satisfy the special building engineering better concrete body structure surface clear water, smooth requirement, need not secondary and plaster, need not face finish and handle; The ribs that the cross section is " C " type makes the installation and removal of panel and support leg all very convenient.

The specific embodiment

Shown in Figure 1 is the embodiment of novel steel framework wooden form.The steel framework wooden form is made of panel 1, frame 2, ribs 3, and frame 2 is " R " type frame, and the hollow steel pipe that is " R " type by the cross section is made (as shown in Figure 3, Figure 4), and four " R " type frames are pressed the normal width specification and formed rectangular frame.The rectangular frame of present embodiment is 1200mm * 3300mm, and adjusting range is between 200-1200mm.As shown in Figure 4, " R " type frame section comprises baseplane 21, big straight flange 22, flanging 23 and plane 24, top, big straight flange 22 grows plane, top 24 and forms inner face, it grows part and equates with the thickness of employed panel 1, as 18mm, panel 1 side is near this inner face, and flanging 23 is connecting baseplane 21 and plane 24, top, and panel 1 is that the delta wood veneer of 1200mm * 3300mm * 18mm is made and is fixed on the plane 24, top by specification.The middle part, baseplane is slightly recessed, and there is arc chord angle both sides, has to seal the function that connects two sides, strengthens side angle rigidity, makes things convenient for jig to connect." R " molded breadth degree of present embodiment frame 2 is 40mm, and the distance between baseplane 21 and the plane 24, top is 100mm.

Between two long limits of rectangular shaped rim 2, be provided with the ribs 3 that the cross section is " C " type; Ribs 3 is provided with nine roads in the present embodiment in width is 1200mm panel 1; Described ribs 3 is the steel hollow section, uses the steel plate of 100 * 90 * 29 * 3 (mm) to make " C " type (as shown in Figure 5), and two rib pin 31 of its " C " type opening part curve inwardly, and the stiffness factor of " C " type ribs 3 is big, and supporting width is big.

On the plane, top 24 of " R " type frame 2 and " C " type ribs 3 tops 32 are furnished with screw hole respectively with the corresponding position of opening, be fastenedly connected respectively from panel 1 back side and frame 2 and ribs 3 by the screw 4 that uses M5 * 8, can guarantee that panel 1 positive no eyelet, no convex-concave vestige also can be connected firmly.

The big straight flange 22 of " R " type frame of steel framework wooden form is the external seal face of template assembly in the construction, inwardly form the scrobicula face in the utility model in the middle of the big straight flange 22, two planes are sealing surface up and down, reduced the contact surface of adjacent frame when making two template assemblies, therefore sealing is tightr, be not prone to spillage, run the slurry phenomenon, improved construction quality.

Parts on the plane, top 24 of " R " type frame near big straight flanges 22 inwardly form concave surface, can absorb panel 1 edge because of thickening that moisture absorption and expanded by heating produce, and avoid influencing the concrete surface quality.

This novel steel framework wooden form adopts the ribs 3 of " C " type, the quantity and the position of screw hole can be set arbitrarily as required, not only can regulate the position of trip bolt 4 according to the construction needs arbitrarily, make things convenient for location and loading and unloading between panel and the ribs, this kind new structure also makes template and being connected of operating platform, support leg convenient, quick simultaneously.
