Problems solved by technology

Ordinary wood formwork adopts wood formwork and a back flute used to support the wood formwork. Since the wood formwork and back flute are formed separately, the disassembly process is troublesome and the turnover times are low.
The steel formwork is heavy, which is not conducive to handling and assembly. The price is much higher than that of ordinary wood formwork. Although there are many turnover times, it will bring a substantial increase in construction costs for projects that do not need to be turned over two or three hundred times.

preparation example Construction

[0033] A kind of preparation method of splicing type wooden formwork of the present invention, comprises the following steps:

[0034] S1. After drying a plurality of veneers, apply an adhesive to assemble blanks, and obtain slabs after hot pressing;

[0035] S2. Sanding the surface of the slab, repairing and leveling it, and veneering it to obtain a semi-finished wood formwork unit;

[0036] S3. Use an engraving machine to hollow out the hollow groove 11 on the back of the semi-finished wood formwork unit according to the preset requirements, and drill out the connecting holes 12 to obtain the wood formwork unit 1;

[0037] S4. Splicing the wooden formwork unit 1 into a wooden formwork according to preset requirements to obtain a spliced ​​wooden formwork.

[0038] In the preparation method of the present invention, a plurality of wooden formwork units are hollowed out by an engraving machine to get out the hollow grooves 11, and the connection holes 12 are drilled out and t...

Embodiment 1

[0040] The preparation method of the spliced ​​wooden formwork of this embodiment: first make a slab of 43 mm, sand the slab to 40 mm, repair the bottom of the surface with putty, and then paste glass fiber or coated paper again to produce a semi-finished product of 40 mm. The semi-finished product is partially hollowed out by the engraving machine and then drilled on four sides to produce a template unit of the required size, which specifically includes the following steps:

[0041] A. Drying of the veneer: the thickness of the veneer is 1.5-1.7mm (the thickness of this embodiment is 1.6mm), and the drying temperature is 60-80°C;

[0042] B. Blank assembly: The number of structural layers is 31 layers. Starting from the bottom plate, one layer of horizontal veneer and one layer of vertical veneer are arranged alternately. The way of laying glue is to alternately set one layer without glue and one layer of glue. The solid content is 45- 50% phenolic resin glue, cloth glue amou...

Abstract

The invention discloses a spliced wood formwork for building construction. The spliced wood formwork is formed by splicing a plurality of wood formwork units, and at least one hollowed-out groove is formed in the positions, close to the left ends, the right ends, the upper ends and the lower ends of the corresponding wood formwork units, of the back faces of the wood formwork units. At least one connecting hole allowing corresponding splicing connecting pieces to penetrate through is formed in the left end, the right end, the upper end and the lower end of each wood formwork unit, and the connecting holes communicate with the hollowed-out grooves. The spliced wood formwork for the building construction has the advantages of multiple turnover times, short mold assembling and disassembling time and simple construction.

Description

technical field [0001] The invention relates to the field of building templates, in particular to a wooden template for building construction and a preparation method thereof. Background technique [0002] In building construction, the formwork project is an important project. The quality of the formwork affects the quality and construction safety of the concrete project. At the same time, whether the formwork can be disassembled quickly will affect the construction progress of the project. At present, the entire construction industry still mainly uses ordinary wood formwork or steel formwork. In recent years, a small amount of aluminum alloy splicing formwork has replaced wood formwork and steel formwork in building construction. Ordinary wood formwork uses wood formwork and a back flute for supporting the wood formwork. Since the wood formwork and the back flute are formed separately, the disassembly process is troublesome and the turnover times are low. At the same time, ...
