Description
Technical field
The utility model relates to building unit field, specifically a kind of assembled concrete arch top board.
Background technology
Because the top board of underground structure will bear larger pressure, therefore generally adopt the structure of arch.Existing arch top board adopts the method for cast-in-situ concrete to construct, and this construction method has quality and is difficult to ensure the shortcomings such as card, formwork are difficult, it is huge to expend, long construction period.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of reliable in quality, with low cost, technical scheme that is simple and safe and the assembled concrete arch top board of short construction period of constructing.
Technical problem to be solved in the utility model realizes by the following technical solutions: a kind of assembled concrete arch top board, comprise multiple prefabricated arch top board, described prefabricated arch top board is the plate body of arch, and the lower end, both sides of prefabricated arch top board is provided with side wall inserting groove; The two ends of prefabricated arch top board are respectively equipped with flange and the groove of form fit, the end face of described flange and groove is arch and arranges continuously along two end faces of prefabricated arch top board respectively, and multiple prefabricated arch top board is connected as one by flange and groove head and the tail.
The technical solution of the utility model also has: the cross section of described flange and groove is rectangle.
The technical solution of the utility model also has: the cross section of described flange and groove is semicircle.
The technical solution of the utility model also has: the width of described prefabricated arch top board is 4500 ~ 7000 millimeters.
The technical solution of the utility model also has: the thickness of described prefabricated arch top board is 150 ~ 350 millimeters.
The technical solution of the utility model also has: the length of described prefabricated arch top board is 2000 ~ 6000 millimeters.
Relative to prior art, the beneficial effects of the utility model are:
(1) due to prefabricated arch top board of the present utility model be tie up muscle, formwork in the factory, build, maintenance and making, therefore its quality is better than cast in situs, ensure that workmanship, and owing to being in factory's centralized production, the dispersion avoiding the resource such as material, electric power uses, waste reduces, with low cost, also reduce the impact of cast in situs construction on surrounding environment, shorten construction period;
(2) assembled concrete arch top board of the present utility model is assembled by multiple volume, the grafting of weight rational prefabricated arch top board, and the process of the transport of precast concrete arch top board, lifting, installation is simple, safety;
(3) end face of flange and groove is arch and arranges continuously along two end faces of prefabricated arch top board respectively, ensures the waterproof effect of assembled concrete arch top board.
