Description

Floor construction joint side template

Technical Field

The utility model relates to a building engineering construction field, concretely relates to floor construction joint side form board.

Background

In the concrete pouring construction of the floor slab, because of design requirements or construction requirements, firstly, concrete of a part of areas, namely a first pouring area, is poured, and after a period of time, concrete of the rest areas, namely a second pouring area, is poured, and the concrete poured successively is combined into a whole. The construction joint is a joint formed at the joint of the successively poured concrete. The upper and lower plate steel bars crossing the successive casting areas need to be installed before casting concrete, and a construction joint side formwork needs to be installed at a construction joint when casting concrete, so the upper and lower plate steel bars need to pass through the side formwork. Therefore, the installation and the removal of the side templates are troublesome, and slurry is easy to leak at the side templates. After the concrete is poured firstly, before the concrete is poured secondly, the concrete at the construction joint needs to be cleaned, floated, loosened and roughened, so that the concrete is combined closely.

The traditional construction joint side template adopts a batten template, and because the reinforcing steel bars of the template block, the template is usually damaged when being removed, so that the template cannot be reused. Although the dense mesh steel formwork net and the fast and easy closing net which are developed later solve the problem of difficult formwork removal, meshes of the dense mesh steel formwork net and the fast and easy closing net are easy to leak slurry, the strength of concrete is adversely affected, and the interface of the concrete poured in advance at the construction joint needs to be cleaned before the concrete is poured in later, so that time and labor are wasted.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned of prior art, the utility model provides a floor construction joint side form convenient to dismantle.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:

the side template for the floor construction joint comprises a rubber plate and a wood back plate, wherein one surface of the rubber plate is provided with a plurality of irregular bulges, and the other surface of the rubber plate is a smooth plane; the upper end and the lower extreme of rubber slab set up the first gap that upper portion reinforcing bar and lower part reinforcing bar on a plurality of confession floor passed respectively, and wooden backplate sets up smooth plane one side on the rubber slab, and the lower extreme of wooden backplate sets up the second gap that a plurality of confession floor upper portion reinforcing bars passed, and wooden backplate is placed on the reinforcing bar of lower part to tripod through a plurality of intervals sets up fixes on the floor template.

Further, the height of the plurality of irregular protrusions is 10-15 mm.

Further, the width of the first slit is smaller than the diameters of the upper and lower reinforcing bars.

Further, the thickness of the wood back plate is more than 20 mm.

Further, the height of the second gap is smaller than the height of the upper reinforcing steel bar, and the width of the second gap is equal to the diameter of the upper reinforcing steel bar.

The utility model has the advantages that: the scheme is used for the side template provided for the construction joint in the concrete pouring process, and the rubber plate can enable the side surface of the poured concrete to form an uneven combined surface without later cleaning and roughening; the upper end and the lower end of the rubber plate are provided with first gaps, so that the rubber plate can be conveniently taken out after concrete is solidified and can be recycled; the size of first gap is less than the size of upper portion reinforcing bar and lower part reinforcing bar for form the extrusion after upper portion reinforcing bar and lower part reinforcing bar pass first gap, and further extrude the rubber slab after concrete placement, make first gap reduce, be favorable to preventing the hourglass thick liquid phenomenon.

When the wood back plate is placed on the lower reinforcing steel bars, the second gap is smaller than the upper reinforcing steel bars, and a gap is formed between the wood back plate and the floor slab, so that the wood back plate is convenient to take out; the tripod is used for supporting the wooden back plate, so that concrete can be poured conveniently.

The steel plate pouring device comprises a first pouring area, a second pouring area, an upper reinforcing steel bar, a lower reinforcing steel bar, a rubber plate, a wood back plate, a protrusion, a tripod, a second gap, a first gap and a second gap, wherein the first pouring area is 1, the second pouring area is 2, the second pouring area is 3, the upper reinforcing steel bar is 4, the lower reinforcing steel bar is 5, the rubber plate is 6, the wood back plate.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

As shown in fig. 1 and 2, the floor construction joint side template comprises a rubber plate 5 and a wood back plate 6, wherein one surface of the rubber plate 5 is provided with a plurality of irregular bulges 7, and the other surface is a smooth plane; the upper end and the lower extreme of rubber slab 5 set up a plurality of first gaps 10 that supply upper portion reinforcing bar 3 and lower part reinforcing bar 4 on the floor to pass respectively, and smooth plane one side of wooden backplate 6 setting on rubber slab 5, the second gap 9 that a plurality of confession floor upper portion reinforcing bar 3 passed are seted up to the lower extreme of wooden backplate 6, and wooden backplate 6 is placed on lower part reinforcing bar 4 to tripod 8 through a plurality of intervals setting is fixed on the floor template.
