Abstract
The utility model relates to a molding frame for assembling of bridge frameworks. The molding frame for the assembling of the bridge frameworks comprises concrete blocks arranged on ground and a plurality of rows of Bailey truss sheets vertically arranged above the concrete blocks, the concrete blocks are cuboid-shaped preformed units, and connection sheets connecting the Bailey truss sheets are arranged in each row of Bailey truss sheets, and the molding frame for the assembling of the bridge frameworks belongs to the technical field of bridge construction. The molding frame for the assembling of the bridge frameworks is stable in support, and convenient to construct, and can effectively guarantee the assembling precision of the bridge frameworks.
Description
Technical field
The utility model relates to a kind of support for assembly unit bridge skeleton, belongs to technical field of bridge construction.
Background technology
At present, China just actively implements cruiseway upgrading training works, carries forward vigorously the construction of high-grade waterway net.Bridge construction on water transport busy river course, construction period must not stop navigation for a long time, so must select in construction the minimum constructure scheme of navigation channel impact.According to the maritime sector requirement, if support is set in the navigation channel, its net span must not be less than 40m, the navigation limit for height must not be less than 7m, if adopt the construction of limited bracket method, the support that arranges in the navigation channel is subject to the passing ships collision unavoidably, jeopardize the boats and ships shipping safety, the potential safety hazard of support self is very large simultaneously.More appropriate constructure scheme be first with the bridge skeleton in bank assembly unit moulding, then lift.Because the terrain environment complexity on bank is various, how to guarantee that bridge skeleton precision in bank assembly unit process is higher and it is convenient to construct, be the problem that those skilled in the art need to solve.
The utility model content
The technical problem that the utility model solves is, proposes a kind of supporting ﹠ stablizing, and constructability can effectively guarantee the bridge skeleton assembly unit moulding bed of bridge skeleton splicing accuracy.
In order to solve the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of bridge skeleton assembly unit moulding bed comprises many row shellfish thunder sheets of being located at ground concrete block and being vertical at the concrete block top; Described concrete block is the cuboid prefabricated component, is provided with the brace that connects shellfish thunder sheet between described every row shellfish thunder sheet.
The operating space is larger when making the assembly unit of bridge skeleton, construct more convenient, a kind of technique scheme preferably: above-mentioned shellfish thunder sheet has two rows, and described two row shellfish thunder sheets are symmetrical arranged along the length direction of described concrete block, and spacing is 600mm to 1200mm.
In order to increase the width of support, guarantee the stability that supports, a kind of technique scheme preferably: above-mentioned every row shellfish thunder sheet is arranged side by side by two shellfish thunder sheets and abutting end is fixedly connected with and consists of.
For the setting that makes shellfish thunder sheet more stable, the stability that guarantee to support better, a kind of technique scheme preferably: above-mentioned brace is made of rectangular frame and the ribs be located in described rectangular frame.
Bridge skeleton of the present utility model assembly unit with the beneficial effect of moulding bed is: this concrete block that moulding bed employing bearing strength is high, shape is regular is as pedestal, adopt shellfish thunder sheet easy to assembly, that hollow part is more, intensity is higher as support, simple for structure, arrange conveniently, even bank terrain environment complexity is various, also can effectively guarantee stability, the accuracy of the assembly unit of bridge skeleton, and operating personnel carry out assembly unit, the welding time space is sufficient, easy construction.

The specific embodiment
Embodiment 1 bridge skeleton assembly unit moulding bed
The bridge skeleton assembly unit moulding bed of the present embodiment as shown in Figure 1 to Figure 3, comprises the shellfish thunder sheet 6 of being located at ground concrete block 5 and being vertical at the concrete block top.Concrete block 5 is the cuboid prefabricated components that formed by the concreting that strength grade is C25, and length is 6000mm, and width is 1800mm, is highly 500mm.Shellfish thunder sheet 6 has two rows, and two row shellfish thunder sheets 6 are symmetrical arranged along the axis a of concrete block length direction, and spacing is 900mm.Every row shellfish thunder sheet 6 is arranged side by side by two shellfish thunder sheets 6 and abutting end is fixedly connected with and consists of.Be provided with the two ends of the symmetrical shellfish thunder sheet 6 of connection and the brace 7 at middle part between two row shellfish thunder sheets 6.Brace 7 is made of rectangular frame 71 and the ribs 72 of being located in rectangular frame.
The assembly unit forming method of application examples 1 arch rib section
The concrete steps of the assembly unit forming method of arch rib section that should use-case are: first the arch rib section prefabricated component that makes is transported to the job site.As shown in Figure 4 and Figure 5, bank at the construction field (site) arranges moulding bed according to shape and the size of arch rib section 31, arch rib section prefabricated component horizontal is set up in is assembled into arch rib section 31 on moulding bed.When assembly unit, fill out steel plate by plug between adjacent arch rib section prefabricated component the shape and size of arch rib section 31 are finely tuned, be welded and fixed between arch rib section prefabricated component.
The assembly unit forming method of application examples 2 half bridge face stiff skeleton sections
The concrete steps of the assembly unit forming method of bridge floor stiff skeleton section that should use-case are: adopt the method identical with the assembly unit forming method of the arch rib section of application examples 1.As shown in Figure 6, at the construction field (site) bank arranges moulding bed according to shape and the size of bridge floor stiff skeleton section 41.Bridge floor stiff skeleton section prefabricated component horizontal is set up in is assembled into two bridge floor stiff skeleton sections 41 that be arranged in parallel on moulding bed.Be welded and fixed between bridge floor stiff skeleton section prefabricated component.
The described concrete technical scheme of above-described embodiment that is not limited to of the present utility model, all employings are equal to the technical scheme of replacing formation and are the protection domain that the utility model requires.
