Description

Technical Field

[0001] The utility model relates to a casting formwork structure for inclined trapezoidal precast components. Background Art

[0002] The precast berthing component is a trapezoidal component with an inclined plane commonly used in wharf engineering. Currently, there are two common casting processes in the precast yard;

[0003] Method 1: Erect the berthing component for casting, that is, with the inclined plane facing down and the direction of the extended reinforcement facing up for casting. However, this method has problems: First, there are cases where the reserved extended reinforcement is too long and too dense, resulting in inconvenient casting, and it is only applicable to some components with shorter reserved reinforcement. Second, a separate support needs to be set up for the formwork at the inclined plane, which is time-consuming and laborious for installation and disassembly.

[0004] Method 2: When casting, the inclined plane of the berthing component faces up, and the reserved extended reinforcement is arranged parallel to the ground. This method solves the problems existing in Method 1 and is applicable to various berthing components. However, this method has the following problems: When the inclined plane of the component faces up and the top surface concrete is cast from bottom to top, the vibration of the concrete in the upper part of the inclined plane causes the concrete to flow and slide down along the slope, resulting in the accumulation of concrete in the lower part of the slope and inability to form. To avoid this situation, when workers cast the concrete in the inclined triangular area, they often reduce vibration or even do not vibrate, resulting in insufficient vibration of the concrete in the inclined triangular area. Eventually, there are series of quality defects such as non-dense concrete, many air bubbles, and rough top surface finishing in the upper inclined triangular area of the finished component;

[0005] Therefore, in view of the above problems, a casting formwork structure for inclined trapezoidal precast components is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a casting formwork structure for inclined trapezoidal precast components to overcome the existing defects, improve the quality problems, and significantly improve the entity quality of the components.

[0007] The technical solution to achieve the above purpose is: A casting formwork structure for inclined trapezoidal precast components, including a surrounding plate assembly, three groups of inclined plane formwork assemblies, multiple groups of sliding door assemblies, and multiple groups of fixing assemblies; the upper end of the surrounding plate assembly is an inclined plane, and the three groups of inclined plane formwork assemblies are laid on the upper end of the surrounding plate assembly; multiple groups of the sliding door assemblies are arranged on each group of the inclined plane formwork assemblies; the three groups of inclined plane formwork assemblies are respectively connected to the upper end of the surrounding plate assembly through multiple groups of the fixing assemblies.

[0008] Preferably, the surrounding plate assembly includes a bottom plate, a front plate, a rear plate, and two side plates. The two side plates are trapezoidal; the front plate is connected to the front side of the upper end surface of the bottom plate, the rear plate is connected to the rear side of the upper end surface of the bottom plate, and the two side plates are respectively connected to the left and right sides of the upper end surface of the bottom plate.

[0009] Preferably, the slope surface formwork assembly includes a slope panel, and reinforcing angle steels are connected to the four sides and the back of the slope panel; six vibration reserved holes are formed in the slope panel, and a set of the sliding door assemblies are arranged on each of the vibration reserved holes.

[0010] Preferably, the sliding door assembly includes a door frame, the door frame is connected to the slope panel by screws, above the vibration reserved hole, and a plugging slider is slidably connected to the inner side of the door frame.

[0011] Preferably, the fixing assembly includes a plurality of fixing blocks and a plurality of movable buckles; the upper end surfaces of both ends of the slope panel are respectively connected with the fixing blocks, and the movable buckles are connected to the upper ends of the side walls of the side plates for connecting the fixing blocks.

[0012] Preferably, a plurality of lifting hooks are connected to the upper end surface of the slope panel.

[0013] Preferably, component reserved holes are formed in the slope panel.

[0014] Preferably, the bottom plate is made of a concrete pedestal and steel plates; the front plate, the rear plate and the two side plates are all welded by steel panels and horizontal and vertical section steel back ribs; the side plates are connected to the front plate and the rear plate on the front and rear sides by bolts.

[0016] The beneficial effects of the present utility model are as follows: The casting formwork structure of the inclined surface trapezoidal precast member solves a series of quality problems such as the concrete in the finished member being not dense, having many air bubbles, and the top surface finishing being rough caused by insufficient vibration of the concrete in the slope triangular area of the trapezoidal member, and significantly improves the entity quality of the member.

[0025] As Figure 1As shown in the figure, the bulkhead assembly 1 includes a bottom plate, a front plate 11, a rear plate 12 and two side plates 13. The two side plates 13 are trapezoidal. The front plate 11 is connected to the front side of the upper end surface of the bottom plate, the rear plate 12 is connected to the rear side of the upper end surface of the bottom plate, and the two side plates 13 are respectively connected to the left and right sides of the upper end surface of the bottom plate.

[0029] Specifically, during concrete pouring, first, the area below the lowest point of the slope surface is subjected to layered pouring and vibration of concrete, and then the slope triangular area is subjected to layered and segmented pouring. Before pouring each segment of the slope triangular area, first fix the slope surface formwork assembly 2 of this segment. The concrete is poured in layers to the highest point of the formwork. The concrete below the formwork is vibrated by inserting a rod through the vibration reserved hole 23. After vibration, the plugging slider 33 at the vibration reserved hole 23 is closed.

Moreover, the structure is simple, and the processing and operation are convenient; the slope surface formwork assembly 2 is composed of commonly used steel shapes, bamboo plywood and other tools on site, with a simple structure, which can be processed and assembled on site by itself. In addition, the weight of a single formwork is light, and the installation and disassembly can be directly carried out by workers manually. And the formwork adopts a snap-type fixing device, which is convenient to operate. At the same time, the production efficiency is improved. Compared with the conventional trapezoidal component pouring method, the concrete formwork device effectively controls the phenomenon of concrete sliding during vibration, reduces the waiting time for concrete hardening, improves the vibration efficiency of the component, and the top of the component is basically formed after being removed, improving the efficiency of subsequent surface finishing, saving labor and improving production efficiency. Moreover, the construction cost is reduced. The concrete wasted due to the sliding of concrete caused by vibration is avoided, the accuracy of the concrete volume is ensured, and the concrete cost is reduced; the improvement of the component quality reduces the expenses generated by the repair of quality defects in the later stage, and the benefits are obvious.
