Description

Facade formwork

This creation involves concrete formwork, especially for the formwork used to infuse the exterior walls.

In the construction of concrete foundations, in the formation of concrete walls or columns, a group of forms are used to connect together in various ways to define a grouting space. The grouting space will be filled with concrete to form a concrete wall or column. Each formwork will be removed after the concrete is consolidated. It is common that the two formwork sheets are locked and fixed at intervals by a fixture.

However, for special construction environments, such as when a concrete foundation is applied next to an obstacle (another building), the construction worker is not easy to implement the formwork (or scaffolding) between the obstacle and the precast concrete foundation area, so On the outside of the predetermined concrete foundation (wall) structure, there is not enough space to support the structure of the outer formwork, and the application position of the concrete foundation must be retracted. This will inevitably reduce the effective use of space inside the building.

See the Republic of China Patent Gazette Bulletin No. M528347 "Metal Formwork for Construction", which is mainly designed for the dismantling of metal formwork for the concrete filling of external walls. It uses rectangular metal plates as the exterior wall of the building. The inner surface and the outer surface are separated, and a concave portion is formed on the inner surface surface. The concave portion includes a plurality of screw caps welded around the concave portion, and a peripheral wall is formed around the concave portion. The bolts are screwed together to form a uniform grouting space between the rectangular metal plate and the inner wooden formwork of the building. The rectangular metal plate can be used as a non-removable formwork to increase the strength of the external wall structure. Wooden formwork The uniformly spaced grouting space can make the thickness of the outer wall manufactured uniformly.

The above-mentioned disassembly-free design in the previous case can save the installation space of the scaffold and save the inconvenience of disassembly, but its size must be specially customized and the nut needs additional welding processing, which makes it quite inconvenient to implement. ; For example, assuming that the rectangular metal plate is designed to have a width of 1 meter, and the width of the pre-filled concrete exterior wall is 8.5 meters, the additional 0.5 meter size will be specially customized. In construction, because the concave portion of the rectangular metal plate must be bent and formed with large machinery, the constructor must specially order a rectangular metal plate with a special width in advance to respond to the construction, which makes it quite inconvenient to prepare materials; The cap is fixed by spot welding. There is a concern about insufficient strength. After the grouting space is filled with cement mortar, the nut that provides bolting and screwing will withstand the tensile force generated by the load. If the nut welding point breaks, it will seriously affect Robustness of formwork.

The purpose of this creation is to provide an external wall formwork structure, which has the advantages of being suitable for implementation in a narrow environment and convenient for erection work, and can resist the warpage and deflection path under load to improve the bonding strength between the forms.

The exterior wall template formed according to this creation includes a board and connectors. The plate has an outer surface and an inner surface separated by a thickness direction, and two opposite first and second end walls located on the outer edge of the template are opposite to two perpendicular to the first and second end walls. The first and second side walls, the first end wall and the second end wall are provided with a slot extending through the end thereof, the slot is formed with an opening on the inner surface, and the width of the opening is smaller than the slot slot width ; The connecting member will be received in the card slot, and the connecting member will be connected to the fixing member.

In one embodiment, the first side wall of the plate body has a first end and a second end. An embedded portion between the walls, and the second side wall has an embedded groove extending between the first and second end walls, and the sectional shape of the embedded groove is the same as that of the embedded portion.

Preferably, the outer wall template further includes a reinforcing strip for closing the slot opening, the reinforcing strip has two relatively long sides and two relatively short sides, and a top surface and a bottom surface formed in the thickness direction, The bottom surface has a shoulder portion extending between the two short sides on each of the two long sides, and both sides of the opening of the plate body further include a through groove for providing the shoulder portion to pass through.

In one embodiment, the plate has a through hole passing through the first and second end walls between the first end wall and the second end wall.
