Embodiment Construction

[0007] In order to overcome the above-mentioned problems, the present invention adopts the following technical scheme, where the plastic formwork 1 (or wood-plastic formwork) needs to be anti-deformation, and the two sides of the square wooden block 5 are used to stick two rubber blocks 2 to the outer surface of the above-mentioned plastic formwork. In this rubber module 2, a nut is set in the upper body of the rubber module 2 through a vulcanization process. The upper end of the above square block is placed in the pit at the lower end of the fixed cap 4 made of plastic. The fixed cap is provided with two The two bolt holes are respectively opposite to the threaded holes on the nuts in the rubber block bonded on the plastic formwork.

[0008] In the operation method of the present invention, the square wood block is placed on the plastic plate, and then two rubber blocks are fixed on both sides of the square wood block with glue. When bonding, use the elastic denaturation of t...

Abstract

The invention discloses a bare concrete formwork and square timber connection structure. The connection structure comprises a square timber block, two rubber blocks are respectively fixed on plastic formworks on two sides of the square timber block through a gluing method, nuts are embedded on upper portions of the rubber blocks, a pit of a fixing cap is sleeved at the upper end of the square timber block, and bolt holes are arranged on two sides of the pit of the fixing cap and opposite to threaded holes of the nuts in the rubber blocks respectively. The bare concrete formwork and square timber connection structure has the advantages that the formworks are not damaged, and the evenness and the smoothness of the cast wall surface are apparent.

Description

Technical field: [0001] The invention relates to a construction tool, in particular to a connection structure between fair-faced concrete formwork and square timber. Background technique: [0002] When casting on fair-faced concrete walls, in order to obtain a surface with high flatness and smoothness, high-smooth wood-plastic formwork is widely used. Due to the thinner formwork and poor rigidity, the formwork will be deformed when pouring concrete, which will affect the surface of the wall. Flatness, the existing technical measures are to fix a square of wood by screws or nails on the outer surface of the formwork. When the formwork is removed and used again, the position of the square wood needs to be changed sometimes, and nail holes will be left on the formwork, so that holes will be produced on the surface of the formed wall, which needs to be repaired manually. Invention content: [0003] The object of the present invention is to provide a connection structure betwe...
