Description

Building formwork joint construction

The present invention relates to a metal connection structure for building formwork, especially metal formwork for building.

At present, the building formwork is still mainly made of wooden boards nailed into unit formwork, and then the wooden corner material is used to support the nailing and assembly. The wooden formwork is easy to be damaged when it is assembled and removed when it is used, which reduces the recovery rate; and recycling The damaged formwork used again will cause the unevenness of the wall surface, which needs to be repaired, which increases the man-hour and material costs. Therefore, a metal template with a high recovery rate was developed later, but due to the limited size of the standardized metal template, the versatility is not high. Therefore, how to solve the shortcomings of building formwork recovery rate and versatility, and the need to measure and cut the formwork still need to be improved.

The prior art researches on a system formwork, as disclosed in the Republic of China Patent No. TW200912104A, which is composed of a group of formwork units connected with large horizontal supports and large vertical supports with adjustable curvature. Among them, the basic formwork unit is composed of a plastic panel combined with a plurality of linear small supports; each small support is fixed on the plastic panel in parallel intervals. Applying this system, the two-dimensional adjustable formwork can be assembled into two-dimensional adjustable formwork in the plane direction of the vertical small support according to the curvature requirements of the structure to pour concrete. In addition, when the light-transmitting panel is used, the position where the concrete is not fully compacted can be dealt with immediately during the grouting construction, which relatively improves the structural quality and reduces the man-hours for surface treatment after formwork removal.

The prior art is aimed at a multi-story RC building rapid construction method and its formwork structure research, as disclosed in the patent number TW461932B of the Republic of China. It uses the first formwork structure to make a multi-story RC structure building without waiting for the concrete of each floor If the structure is dry and stable, the construction of the concrete structure of the upper floor can be carried out immediately, so as to greatly shorten the construction period, and the concrete structures of each floor are well combined with each other to improve the overall strength and earthquake resistance.

The prior art is directed at a composite hollow flat plate and its manufacturing method. As disclosed in Chinese Patent No. CN110344581A, the reinforcing layer is reinforced with continuous fibers, embedded in the template through a pultrusion process, and melted into a whole. Improve product performance. In the case of the same cross-sectional area, compared with the prior art, the strength of the present invention is higher. In the case of ensuring consistent strength, its cross-sectional area is smaller, so that the weight can be reduced. The reinforcement layer is reinforced with continuous fibers, which greatly increases the flexural modulus, effectively increases its impact resistance, greatly improves its resilience and improves its service life. The manufacturing method adopts a composite process to ensure the continuity of the continuous fiber throughout and will not be sheared by the engagement of the screw. By adopting the manufacturing method, the structure adjustment is simple, the width can be customized through the mould, and the length direction can be cut arbitrarily. The templates of the prior art still need to be cut to assemble and fill the required area of the wall surface, and the recycling rate of the templates is low.
