Rubber waterstop and foam board fixing device for box culvert continuous placement and using method thereof

Abstract

The invention discloses a rubber waterstop and foam board fixing device for box culvert continuous placement and a using method thereof. The fixing device involves a rubber waterstop, foam boards, steel bar supports, bolts and mortar cushion blocks, the rubber waterstop is of a rectangular sheet-shaped structure, anti-skid protrusions are arranged on the two faces of the rubber waterstop, each steel bar support comprises a waterstop fixing rib, a foam board fixing rib, a rubber water-stopping anti-skid distribution rib, a connecting rib, a steel plate with a hole and an inclined supporting ribwhich are welded together to play a role of a fixing support, the bolts comprise screw rods and nuts and play a role in connecting the steel bar supports on the two sides of the waterstop to clamp and position the waterstop, and the mortar cushion blocks are trapezoidal mortar cushion blocks, are bound on the foam board fixing ribs and cooperate with the supports to play a role in fixing the foamboards. The fixing device has the advantages that the fixing problem of the rubber waterstop and the foam boards during box culvert continuous placement is solved, moreover, the structure is simple,fixing and connecting are convenient, on-site machining is facilitated.

Description

Technical field: [0001] The invention relates to two kinds of installation tools for building construction materials, in particular to a rubber waterstop and foam board fixing device for pouring box culvert continuous warehouses and a method for using the same. Background technique: [0002] Box culvert projects generally require expansion joints, and buried rubber waterstops are often used to prevent leakage at the expansion joints, and closed-cell foam boards are filled in the expansion joints. The conventional concrete pouring method for box culverts is bundling, which is convenient for fixing the rubber waterstop. After removing the formwork, paste the foam board on the expansion joint, and there is no problem of fixing the foam board. However, the bundling There are many formwork and formwork removal methods, which are labor-intensive, high cost, and long construction period; the amount of concrete poured at one time is small, and the amortization cost is large. The us...

Problems solved by technology

The conventional concrete pouring method for box culverts is bundling, which is convenient for fixing the rubber waterstop. After removing the formwork, paste the foam board on the expansion joint, and there is no problem of fixing the foam board. However, the bundling There are many ways to set up and remove the formwork, which is time-consuming, high cost, and long construction period; the amount of concrete poured at one time is small, and the amortization cost is large

The use of box culvert continuous warehouse pouring can reduce the workload of formwork support and form removal, increase the amount of concrete poured at one time, and reduce amortization costs. At the same time, continuous warehouse pouring can reduce the working surface and reduce temporary land occupation. The urban box culvert project is particularly important, but the method of fixing rubber waterstops and foam boards in continuous warehouse construction is quite different from that in jump warehouse construction, and special tools are required for fixing
