Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of window sill top U-shaped prefabricated component construction, in particular to a window sill top U-shaped prefabricated component template reinforcement device. Background Art
[0002] In order to improve construction efficiency, speed up construction progress, and ensure that the window sill top and masonry structure can be constructed simultaneously, the current construction stage usually does not adopt the traditional construction method: first build to the bottom elevation of the window sill top, support the formwork to cast the window sill top, and then build the upper masonry. Instead, the two ends of the window sill top are designed as prefabricated anchor blocks, and the middle of the window sill top is designed as a U-shaped concrete prefabricated component that does not need to be removed from the formwork, also known as a U-shaped formwork.
[0003] During construction, first build the wall to the bottom elevation of the window sill, then install the prefabricated anchor blocks and U-shaped concrete prefabricated components, then build the walls on both sides of the window, and finally tie the window sill top steel bars and pour the window sill top concrete. In this way, due to the installation of anchor blocks and U-shaped concrete prefabricated components, it can be ensured that the masonry above the window sill top is not restricted, and the window sill top and masonry can be built simultaneously, saving construction time and costs.
[0004] At present, there is no better processing method for U-shaped prefabricated concrete components, and wooden formwork is generally used as its forming formwork. Since the U-shaped prefabricated concrete components need to be formed in one step, the formwork on the inside of the U-shaped prefabricated concrete components needs to be reinforced by a hanging formwork. During the hanging formwork reinforcement process, since the size of the U-shaped prefabricated concrete components is generally only 200mm wide, there is only a space with a width of 150mm in the middle for reinforcing the formwork. The small reinforcement space will, on the one hand, lead to the inability to reinforce the formwork when installing it, which is easy to cause poor forming effect of the U-shaped prefabricated concrete components after concrete pouring. On the other hand, it is not convenient to remove the formwork. If the formwork is directly pried for removal, the edges and corners of the U-shaped prefabricated concrete components will be damaged. In addition, since the formwork on the inside of the U-shaped prefabricated concrete component needs to be a hanging formwork, the hanging formwork has no lower support and is suspended in the air. Generally, it is connected to the formwork on the outside of the U-shaped prefabricated concrete component by a tension screw to achieve the fixation of the formwork. In this way, holes will be left on the U-shaped prefabricated concrete component after it is formed. Utility Model Content
