Description

FIELD OF THE INVENTION

[0001] The present invention relates to a constructing method for multiple floors building and moldboard structure employed in the method. The upper floor can be constructed before the concrete in the lower floor is solidified.

BACKGROUND OF THE INVENTION

[0002] In a conventional method for constructing a R multiple floors building, the posts and the steels and moldboards of outer wall are first established, and then proceeding the process of grouting. The upper floor cannot be constructed till the concrete in the walls and posts are solidified. The upper floor is built by the same method as the lower floor of establishing posts, the steels and the moldboards, and grouting. The stairs and ramps are predetermined and the area of the ramps are formed by grouting after the concrete for the inner walls and floor is solidified. On the ramp the stairs are built by way of establishing moldboards and grouting. There are some IS shortcomings found in the conventional method:

[0003] (1) The upper structure can be constructed after the concrete in the posts, moldboards and floor is solidified, and it requires 20 days to let the concrete completely be solidified. This causes a longer period of construction and the financial pressure will be increased if the number of floors is large.

[0004] (2) The grouting for the walls, the posts and the floors is proceeded in sequence so that the connection between the concrete in the walls, the posts and the floors can not be well bound. If the builder proceeds the grouting for the upper floor before the concrete of the lower floor is completely solidified, the building is exposed to a safety consideration.

[0005] (3) The conventional moldboards are made of wood plate connected by nails or steel boards, the wooden moldboards can only be used for 7-8 months and it requires skilled persons to make the wooden moldboards and use the moldboards. If the surfaces of the moldboards are not smooth, the surface of the walls is not smooth. After the wall is built, mortar is spread onto the wall to have a smooth outer surface. These processes take a lot of time and prolong the period of the construction. In other words, this accelerates the financial pressure.

[0006] As the steel boards are cut as needed so that they have no common size and standard. Besides, to lift the steel boards involves potential safety problems.

[0007] Furthermore, the wall is constructed by filling concrete in a space between two moldboards, and the moldboards are aligned by wires. The constructors have to check and adjust the wires to let the space between moldboards has a desired sizes. This makes an uncertainty for the quality of the construction.

[0008] (4) The moldboards are supported by rods which inclinedly contact against the ground. However, most of the grounds are uneven so that constructors have to find blocks having different sizes to put them between the rods and the ground;

[0009] (5) The stairs are built by forming a ramp by grouting and then each step is formed by using the moldboards and then filling concrete in the space enclosed by the moldboards. The conventional method has the following shortcomings:

[0010] 1. The specifications for stairs of different buildings are not identical so that the moldboards used for the respective stairs have to be made separately.

[0011] 2. After the, moldboards are removed, the surfaces of the stairs have to be spread with mortar at least two times to have a smooth surface.

[0012] 3. It takes a lot of time to put tiles on the stairs and this requires many workers to adhere the tiles one by one. The weight of the tiles becomes a large load for the structure of the stairs. Once the tiles are broken or disengaged from the stairs, the owner has to spend money to recover them.

[0013] The present invention intends to provide a new method for constructing RC building and which is simple and can be completed within a short period of time.

SUMMARY OF THE INVENTION

[0014] In accordance with one aspect of the present invention, there is provided a constructing method for multiple floors building and moldboard structure employed in the method. The construction for the upper floor can be proceeded before the concrete for the lower floor is solidified. This method shortens the construction period and enhances the structural strength of the building.

[0015] The primary object of the present invention is to provide a constructing method wherein the marble plates, granite plate or tiles are adhered to the moldboards before grouting so that after the grouting process is finished, and the outer surface of the structure is completed.

[0016] These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
