Fixing device for clamping mold and construction method of clamping mold

Abstract

The invention relates to a sandwich formwork fixing device and a sandwich formwork construction method. The device comprises paired main formworks and one or more side formworks, the main formworks are rectangular slabs, each side formwork is a slab with at least one straight side, and under an assembling state, and the slab surface of each side formwork is perpendicular to the slab surface of the corresponding main formwork and is attached to the end face of a corresponding long side of the corresponding main formwork. The core of the method includes: sandwiching the paired main formworks on two sides of a wall fabricated part, maintaining the paired main formworks and two bedding faces of the wall fabricated part to be arranged parallelly at intervals and fixed, inserting the side formworks at the left, right and upper edges of the exposed wall fabricated part, enabling side formworks and the upper side of an underbeam / foundation to be enclosed all sides, performing formwork pouring for the other side face and columns and beams after concrete sprayed in the enclosed range reaches required strength. A sprayed concrete layer obtained by the device and the method is compact and high in strength and is connected with a cast-in-situ column and a cast-in-suit beam in a high strength manner, and effective matching technology and tools are provided for in-situ spraying construction of sandwiched walls.

Description

technical field [0001] The invention relates to a building formwork and its complete set of fixing tools and a construction method using the tool, mainly suitable for the construction of walls, columns and beams containing sandwich walls, especially suitable for single or double sides of walls Construction constructed by the sprayed concrete method on site. Background technique [0002] Due to the advantages of reducing the self-weight of the wall, improving the thermal insulation effect of the wall, and increasing the construction speed, wall prefabricated parts such as steel mesh sandwich light panels are used more and more in construction, and many applicable Based on this new building construction method of wall prefabricated parts, in which the concrete layer is formed by spraying concrete on the surface of the wall prefabricated parts on site, the construction speed can be further improved compared with the support formwork usually used in the past and then poured conc...

[0002] Due to the advantages of reducing the self-weight of the wall, improving the thermal insulation effect of the wall, and increasing the construction speed, wall prefabricated parts such as steel mesh sandwich light panels are used more and more in construction, and many applicable Based on this new building construction method of wall prefabricated parts, in which the concrete layer is formed by spraying concrete on the surface of the wall prefabricated parts, the construction speed can be further improved compared with the support formwork usually used in the past and then poured concrete on site, resulting in The new problem is that the material at the boundary of the sprayed area is often uneven, loose, and low in strength, so it is usually not used for load-bearing. In addition, since the columns and beams still need to be constructed by pouring in situ, the cast-in-place columns and beams are combined with at least one side of spraying to form concrete How to connect the walls of the layers to achieve the required strength is also a new problem to be solved
