Abstract

The utility model discloses a reservation hole structure of constructional column under board, including cast in situ concrete floor, the reservation hole has been seted up to the position that lies in directly over the constructional column on the cast in situ concrete floor, and pre-buried stagnant water part that has in the reservation hole. In the structure construction process of the utility model, the position of the cast-in-place concrete floor slab with the constructional column is provided with a reserved hole for the corresponding part of the slab; and the plate ribs are continuous and uninterrupted when the hole is reserved, only the concrete pouring port is reserved, and the concrete is reserved layer by layer and poured layer by layer; the damage of the template caused when the steel bars are reserved on the constructional column is avoided.

Description

Hole reserving structure of under-board constructional column

Technical Field

The utility model belongs to the building field, concretely relates to hole structure of reserving of constructional column under board.

Background

In the building construction, when a project constructs a beam bottom constructional column, a dustpan opening pouring mode is conventionally adopted, and in the conventional method, constructional column reinforcing steel bars are reserved in the plate construction, so that the formwork erection and the concrete forming quality are influenced, and the safety of a building main body is further endangered.

Disclosure of Invention

In order to solve the problems, the utility model discloses a simple operation, short construction period; the template damage caused by the steel bar reservation of the constructional column can be effectively avoided; meanwhile, the reserved hole structure of the under-slab constructional column for increasing the cost of the post-planting steel bars is reduced.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a preformed hole structure of structure post under board, includes cast in situ concrete floor, the preformed hole has been seted up to the position that lies in directly over the structure post on the cast in situ concrete floor, pre-buried stagnant water part has in the preformed hole.

As a further improvement of the scheme, the water stopping component is provided with a water stopping sleeve and a water stopping ring, and the water stopping ring is welded on the middle part of the outer circumference of the water stopping sleeve.

As a further improvement of the scheme, the water stop sleeve is of a cylindrical ring structure, and the water stop ring is square or circular.

As a further improvement of the scheme, the lower end of the water stopping sleeve is flush with the lower end of the reserved hole, and the upper end of the water stopping sleeve is 3-10cm higher than the upper end of the reserved hole.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. in the construction process of the structure, arranging a reserved hole on the corresponding part of a plate at the position of a cast-in-place concrete floor slab with a constructional column; and the plate ribs are continuous and uninterrupted when the hole is reserved, only the concrete pouring port is reserved, and the concrete is reserved layer by layer and poured layer by layer; the template damage caused by the steel bar reservation of the constructional column is avoided;

2. the formwork can be conveniently supported and the concrete can be conveniently vibrated, so that the forming quality of the concrete is ensured, and meanwhile, the labor material cost for post-planting reinforcement in the construction of a conventional constructional column is reduced;

3. in addition, only normal binding of reinforcing steel bars is needed, and concrete with the strength level higher than that of original concrete of a floor slab is poured at the reserved hole of the slab after the constructional column is poured;

4. the operation is simple and convenient, and the construction period is shortened; the cost increased by post-planting the steel bars is reduced.

5. The utility model discloses a stagnant water part can avoid the first layer waterproof layer because of wearing wall pipeline and wall body when taking place the displacement (if because of the expend with heat and contract with cold of cavity), also prevents its and wear wall pipeline or upstream face and throw off the infiltration that forms the gap and lead to water because of the connection of second floor waterproof layer.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1, the prior art cast-in-place concrete floor is complete, but there is not enough clearance when the concrete upright post is poured to reach the top, and the dustpan opening is not suitable, and only manual plastering can be performed by using a plastering plate, which results in uneven concrete and poor quality and insufficient strength.

As shown in fig. 2-3, a reserved hole structure of an underfloor constructional column comprises a cast-in-place concrete floor slab 1, a reserved hole 2 is formed in the cast-in-place concrete floor slab 1 and is located right above a constructional column 4, and a water stop component 3 is embedded in the reserved hole 2.

The water stop member 3 has a water stop sleeve 31 and a water stop ring 32, and the water stop ring 32 is welded to the middle of the outer circumference of the water stop sleeve 31.

The water stop sleeve 31 is of a cylindrical ring structure, and the water stop ring 32 is of one of a square shape and a circular shape.

The lower end of the water stopping sleeve 31 is flush with the lower end of the reserved hole 2, so that a formwork can be conveniently supported, and the upper end of the water stopping sleeve 31 is 3-10cm higher than the upper end of the reserved hole 2, so that water is prevented from permeating.

As shown in fig. 4, in the construction process of the structure, at the position of a constructional column 4 of a cast-in-place concrete floor slab 1, a reserved hole 2 is arranged at the corresponding position of a plate; when the hole 2 is reserved, the plate ribs are continuous and uninterrupted, only concrete pouring openings are reserved, and the concrete is reserved layer by layer and poured layer by layer; the destruction of the template caused when the steel bars are reserved in the constructional column 4 is avoided.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement, component separation or combination made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
