Abstract
A rack unloading sand box of a cast-in-sight bridge belongs to the technical field of road and bridge construction and is characterized in that the rack unloading sand box has a tubular shape in structure. A steel pipe and a steel plate are welded and fixed to form a sand box base, and a steel plate and a steel pipe are welded and fixed to form an upper cover. The diameter of the steel plate on the top face of the upper cover is larger than the outer diameter of the steel pipe of the sand box base, and a sand unloading pipe is fixedly connected to the lateral lower face of the sand box base. The rack unloading sand box of the cast-in-site bridge has the advantages that both the sand box base and the upper cover adopt steel pipes so as to have good mechanical performance; welding amount is reduced so that quality is easy to guarantee; the diameter of a top plate of the upper cover is larger than that of the sand box base, thereby being capable of preventing rain and water for maintenance from entering sand in the sand box base and being convenient to unload.
Description
Technical field
The utility model belongs to the construction of road and bridge technical field.
Background technology
At present, at home and abroad in the cast-in-situ bridge construction, all use and unload rack device, the pier boom support unloads rack device often to adopt the structure external form is the sandbox of rectangle at present, is made up of sandbox base, loam cake that welded steel plate forms, and Fig. 1 is seen in its assembling; Steel plate during use, weld seam are stressed unreasonable; Because the sandbox external form is a rectangle, adds and needs cutting steel plate man-hour, the welding job amount is bigger, and quality is difficult for guaranteeing; The lid top panel width is less than the base width on the sandbox, and maintenance water, the rainwater sandbox base inside that intakes is easily strengthened sand moisture, causes and unloads the frame difficulty.
Summary of the invention
The purpose of this utility model is: provide a kind of cast-in-situ bridge to unload the frame sandbox, it has simplified manufacturing process, simultaneously the easier frame that unloads.
The technical solution of the utility model is: unloading frame sandbox structure external form is tubular, adopt the welding of steel pipe and steel plate to be fixed as the sandbox base, adopt the welding of steel plate and steel pipe to be fixed as loam cake, upper cover top surface steel plate diameter is greater than the base outer diameter of steel pipes, is fixedly connected with below the base side and unloads sandpipe.
The beneficial effects of the utility model are: sandbox base, loam cake all adopt steel pipe, and stress performance is better during construction; Welding quantity reduces the easier assurance of quality; Last lid top panel diameter can prevent that greater than base diameter rainwater, maintenance water from entering in the interior sand of base, conveniently unloads frame.
Description of drawings
Fig. 1 is that existing pier boom support unloads frame figure.
Fig. 2 is the utility model sandbox assembly drawing;
Fig. 3 is the utility model sandbox base vertical view;
Fig. 4 is the utility model sandbox loam cake upward view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 2,1 for unloading sandpipe; 2 is dry sand; 3 is stone flour, cement, water mix; 4 is that sandbox base steel plate, 5 is that sandbox base steel pipe, 6 is that loam cake steel plate, 7 is the loam cake steel pipe.
The sandbox base adopts steel pipe 5 and steel plate 4 to be welded as integral body, loam cake also adopts steel plate 6 and steel pipe 7 to weld together, upper cover top surface steel plate 6 diameters are greater than base steel pipe 5 external diameters, fill full after in loam cake steel pipe 7, mixing and stirring with stone flour, cement, water, the dry sand that in base steel pipe 5, adds certain altitude, treat to fill out in the loam cake and after material solidifies, hardens, loam cake is put into base steel pipe 5, form and unload the frame sandbox.
Last lid top panel diameter is greater than the base diameter of steel tube, and maintenance water, rainwater can not enter in the inner sand of base, does not cause the sand water inlet that is used to unload frame in the base; Insert stone flour in the loam cake steel pipe and fill out and expect, without closed above; Can solve the problem that exists in the former sandbox use.
Claims (1)
1. a cast-in-situ bridge unloads the frame sandbox, it is characterized in that: unloading frame sandbox structure external form is tubular, adopt the welding of steel pipe and steel plate to be fixed as the sandbox base, adopt the welding of steel plate and steel pipe to be fixed as loam cake, upper cover top surface steel plate diameter is greater than the base outer diameter of steel pipes, is fixedly connected with below the base side and unloads sandpipe.
