Description

Fabricated splicing partition thin and light formwork

Technical field

The invention relates to a light and thin formwork of an assembled splicing partition wall, which belongs to the field of building materials.

Background technique

At present, the wood formwork commonly used in China's construction industry has the disadvantages of large use of wood and environmental protection. The need to assemble and disassemble the formwork requires a lot of manpower, material resources, and low industrialization of the building. The long-lasting outer retaining wall or inner partition wall is usually constructed by bricks, which has the disadvantages of high labor costs and environmentally-friendly materials, and requires manual plastering in the later stage, which is time-consuming and labor-intensive.

At present, the light-weight partition boards commonly used in prefabricated buildings also have narrow version widths, which require manual handling. Multiple assembly can make one wall in the apartment completely formed. Some prefabricated walls are self-heavy. During the installation process, Tower cranes or lifting equipment must be used for installation, and for some buildings with small building areas and low floors (such as villas) using tower cranes or lifting equipment to install prefabricated components has no cost advantage.

Summary of the Invention

In order to overcome the above-mentioned shortcomings, an object of the present invention is to provide an assembled splicing partition wall light and thin formwork which can realize the assembled construction without a crane. It can replace bamboo and wood formwork, realize mold-free, integrate pipeline installation space, and stabilize its structure; effectively save wood resources, labor costs, cancel hoisting costs, shorten the construction period and improve the degree of industrialization of the building, and can separate the structure from the pipeline The purpose is to improve the building assembly rate on site.

In order to achieve the above objective, the present invention adopts the following technical solutions:

An assembly type splicing partition wall light and thin formwork, the formwork includes two parts, namely a middle splicing model board and an end edge sealing model board;

The structure of the intermediate splicing model plate is composed of two types of cavities; the cavity area enclosed by the end rib and a middle rib adjacent to the panel is a concrete pouring cavity, and the cavity is used for installing steel bars and Pouring concrete

The cavity area enclosed by the middle rib and the two side panels is a conduit installation cavity, and the cavity is used to install the conduit and the socket;

The concrete pouring cavity and the line pipe installation cavity are arranged side by side and spaced apart from each other along the length direction of the middle splicing model plate.

Further, a middle partition is provided in a middle portion of the wire tube installation cavity.

Further, the inner and outer sides of the intermediate splicing model plate are panels with dense ribbed cavities, and the two ends of the intermediate splicing model plate connect the inner and outer two panels into one through end rib plates.

Further, a plurality of holes are evenly distributed on the end ribs.

Further, a plurality of middle ribs are provided between the two inner and outer panels.

Further, the cross-section of the edge-sealing model board is "U-shaped", and the panel of the edge-sealing model board is also a panel with a dense rib cavity.

Further, the intermediate splicing model board and the end-sealing model board are connected together by a card strip; the card strip is divided into a first male card strip, a second male card strip, a first female card strip, and a second female card strip. Card strip

The cross sections of the first male clip and the second male clip are convex, circular cross sections; the cross sections of the first and second female clips are concave, circular cross sections.

Further, the arrangement of the first male card strip and the first female card strip on the middle splicing model board is as follows: two first male card strips are provided on both sides of one end of the middle splicing model board, and two first mother card The strips are set on both sides of the other end of the middle splicing model board.

Further, the edge banding model board is divided into an end banding model board with a second male clip and an end model board with a second female clip.

Further, the first male card strip, the second male card strip, the first female card strip, and the second female card strip are laterally moved toward the other intermediate spliced model board or the edge-sealed model board through the middle splicing model board, thereby achieving Quick splicing of two components.

Specific work implementation process:

A. The middle splicing model board is spliced together two by two by the clips, and after splicing into the shape of a wall, the edge is processed with edge banding model board;

B. At the upper openings of all the concrete pouring cavity areas, insert the vertical steel bars of the structure;

C. After the reinforcement is fixed, the concrete is poured into the area of the concrete pouring cavity;

D. At the upper opening of the tube installation cavity area, insert the lower tube, the panel position of the tube installation cavity area, and open the hole to install the wire box.

The outer surface of the panel can be provided with vertical grooves along the height direction of the model panel according to the requirements of aesthetics or practicality. First, the strength of the panel can be increased. During the concrete pouring process, the amount of deformation of the outer panel will not be excessive. The second is to facilitate hanging the slurry when the surface of the panel is plastered, and the third is to have some decorative effects.

The multi-ribbed cavity of the panel mainly functions to improve the strength of the panel. The cross-section of the multi-ribbed cavity may be square, circular or triangular.

The assembly type splicing partition wall light and thin formwork is an extruded building component made of plastic material, and is an elongated building component.

The panel of the assembled thin-walled thin-and-fabric template can be a flat template or a curved template, which is determined according to the outline of the actual building.

The holes distributed on the reinforcing rib thin plate play the role of the transverse reinforcing steel of the erecting structure, and can also allow the pouring concrete to pass through each other. Its shape can be square, round, oval, polygon, etc.

The beneficial effects of the present invention:

1. The present invention realizes mold-free and mold-removal; brick-free and plaster-free; and slot-free wiring.

2. The element of the invention has a very light weight, and workers can easily move and install it, eliminating cranes or tower cranes;

3. The present invention eliminates wood formwork and bricks, and uses renewable materials to manufacture products, thereby being more environmentally friendly.

4. The invention realizes factory production, which is convenient and fast, and greatly shortens the construction time of the building.
