Abstract
The utility model discloses a blocking structure for small reserved opening members of floor. The blocking structure comprises an inverted-frustum-shaped concrete prefabricated member which is closely plugged in an inverted-frustum-shaped concrete reserved opening of the floor. The shape of the concrete prefabricated member is matched with that of the reserved opening of the floor. Gaps at joints between four sides of the top of the concrete prefabricated member and the floor structure are filled with mortar. The blocking structure has the advantages that secondary casting is omitted for opening blocking, form supporting is omitted, operation is simplified, construction period is shortened, and cost is reduced while work efficiency is improved greatly.
Description
Technical field
The utility model relates to plugging structure, and the utility model relates in particular to the small-sized reserved opening member of floor plugging structure.
Background technology
When Construction of High-rise, the vertical transmission of control axis is generally reserved small-sized hole by floor and is successively upwards carried out, due to the number of plies, the quantity of reserved opening is also considerable more at most, carry out floor sealing hole after use finishes time, the general mode of hanging mould secondary concreting that adopts is carried out, engineering quantity is huge, and construction period is longer.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of simple to operate, save the duration, the small-sized reserved opening member of a kind of floor plugging structure that reduces costs and greatly increase work efficiency.
In order to achieve the above object, the technical solution adopted in the utility model is:
The small-sized reserved opening member of a kind of floor of the present utility model plugging structure, it comprises that jam-pack is at the inversion truncated rectangular pyramids shape concrete prefabricated element of being inverted in truncated rectangular pyramids shape floor slab preformed hole mouth, described concrete prefabricated element shape and floor slab preformed hole mouth-shaped match, and described concrete prefabricated element top surrounding and floor slab structure junction gap filling are wiped with mortar.
The beneficial effects of the utility model are: sealing hole is built without secondary, need not install template, simple to operate, save the duration, reduce costs, and greatly increase work efficiency.
Brief description of the drawings
Accompanying drawing is the structural representation of the small-sized reserved opening member of a kind of floor of the present utility model plugging structure.
Detailed description of the invention
The small-sized reserved opening member of a kind of floor of the present utility model plugging structure as shown in drawings, it comprises that jam-pack is at the inversion truncated rectangular pyramids shape concrete prefabricated element 2 of being inverted in truncated rectangular pyramids shape floor slab preformed hole mouth, described concrete prefabricated element 2 shapes and floor slab preformed hole mouth-shaped match, and described concrete prefabricated element 2 top surroundings and floor slab structure 3 junction gap fillings are wiped with mortar 1.
The construction method of this structure is:
1. when floor slab preformed hole mouth is constructed, inversion truncated rectangular pyramids groove face 4 shapes of " up big and down small " are all arranged at four sides, and corresponding concrete prefabricated element 2 is also prefabricated into the inversion truncated rectangular pyramids shape of " up big and down small ", size and reserved opening consistent size;
2. reserved opening uses and finishes while carrying out sealing hole, by prefabricated units 2 from top to bottom jam-pack in hole, and by prefabricated units 2 top surroundings and floor slab structure 3 gaps, junction employing filled with mortar floating 1.
Claims (1)
1. the small-sized reserved opening member of a floor plugging structure, it is characterized in that: it comprises that jam-pack is at the inversion truncated rectangular pyramids shape concrete prefabricated element of being inverted in truncated rectangular pyramids shape floor slab preformed hole mouth, described concrete prefabricated element shape and floor slab preformed hole mouth-shaped match, and described concrete prefabricated element top surrounding and floor slab structure junction gap filling are wiped with mortar.
