The building flat roof concrete pouring floor comprises a foundation layer on a building flat roof, partition seam forming square steel dies are arranged on the foundation layer, lubricant layers are arranged on two side faces of the partition seam forming square steel dies, right-angle conical fixed mortar layers are arranged on the outer sides of the lubricant layers, and concrete pouring surface layers are arranged on the foundation layer on the outer sides of the right-angle conical fixed mortar layers. However, the rigid mold is removed at last, and the structure of the dividing slit can be damaged in the mold removing process.

Disclosure of Invention

The utility model provides a steel division strip structure for solving the technical problem of roof concrete separation.

The technical scheme of the utility model be, a steel divides batten structure, including structural layer, the slope layer of looking for, screed-coat, waterproof layer, heat preservation, isolation layer, the protective layer that sets gradually from the bottom up, be equipped with in the protective layer and divide the batten, divide batten structure include the channel steel, be equipped with the stationary blade in the bottom of channel steel, the stationary blade passes through the fix with screw on isolation layer and heat preservation, the height of channel steel is the same with the protective layer, the channel steel in be equipped with and inlay the strip.

Compared with the prior art, the utility model discloses a characteristics that steel division strip and concrete expansion coefficient are close under the reasonable condition is separated to the size, can effectively eliminate the crackle that concrete layer expend with heat and contract with cold produced. Meanwhile, the steel separating strips do not need to be dismantled, the concrete flatness and the slope direction of the two sides of the separating strips can be guaranteed, the construction efficiency is improved, and the construction period is shortened. And the rubber filling material is adopted, so that the phenomena of fracture, foot warping, protrusion and the like caused by the influence of weather reasons on the traditional filling material (asphalt sand) can be effectively avoided.

Detailed Description

As illustrated in fig. 1, the embodiment of the utility model provides a steel division bar structure, including structural layer 1, slope finding layer 2, screed-coat 3, waterproof layer 4, heat preservation 5, isolation layer 6, the protective layer 7 that from the bottom up set gradually, be equipped with division bar 8 in protective layer 7, division bar 8 structure include channel steel 9, be equipped with stationary blade 14 in channel steel's bottom, stationary blade 14 passes through screw 11 to be fixed on isolation layer 6 and heat preservation 5, channel steel's height is the same with protective layer 7, channel steel in be equipped with and inlay strip 10.

As shown in FIG. 2, one end of the channel steel is provided with a dovetail groove 13, and the other end is provided with a dovetail clip 12.

Fixing pieces 14 are horizontally arranged on two sides of the bottom of the channel steel, and screw holes are formed in the fixing pieces 14.

The V-shaped groove 8 is formed above the embedding strip 10, and weather-resistant glue is arranged in the V-shaped groove 8.

As illustrated in fig. 3, the dividing strip 9 may be inserted into each other through a dovetail groove 13 and a dovetail 12 to form a straight-line structure, or may form a cross-shaped structure.
