Abstract
The utility model discloses a kind of formwork structure for shutoff exterior wall reserved opening, this formwork structure comprises the exterior sheathing and inner formword that are arranged on reserved opening both sides on exterior wall, described exterior sheathing is the foldable template adopting gemel connection to form by two pieces of symmetrical templates, be provided with in inner formword upper end and build mouth, four angles of exterior sheathing and inner formword arrange the first through hole and the second through hole respectively, and exterior sheathing and inner formword drawknot are fixed through after the first through hole and the second through hole by iron wire.Exterior sheathing of the present utility model and inner formword are fixed by the mutual drawknot of iron wire, therefore, do not set up the support of support shuttering in addition, not only time saving and energy saving, and save construction cost, substantially increase efficiency of construction.
Description
Technical field
The utility model relates to a kind of formwork structure for shutoff exterior wall reserved opening, belongs to technical field of building construction.
Background technology
In the building operations later stage, need the reserved hole on External Wall to carry out shutoff, be generally install template in reserved hole both sides, then concreting carries out shutoff.But, this method for blocking needs outside outer both sides within the walls to set up the support for support shuttering, particularly exterior wall outrigger, along with the increase of story height, set up support pipe fitting used and fastener more, too high support must cause structural stability to be deteriorated, and there is potential safety hazard, and support is set up and is wasted time and energy, and increases difficulty of construction.In addition, the existing template for shutoff reserved opening, all as disposable template, can not reuse, and causes construction cost to increase.
Utility model content
The purpose of this utility model is, provides that a kind of structure is simple, easy construction the formwork structure for shutoff exterior wall reserved opening that can reuse, to overcome prior art deficiency.
The technical solution of the utility model: a kind of formwork structure for shutoff exterior wall reserved opening, comprise the exterior sheathing and inner formword that are arranged on reserved opening both sides on exterior wall, described exterior sheathing is the foldable template adopting gemel connection to form by two pieces of symmetrical templates, be provided with in inner formword upper end and build mouth, four angles of exterior sheathing and inner formword arrange the first through hole and the second through hole respectively, and exterior sheathing and inner formword drawknot are fixed through after the first through hole and the second through hole by iron wire.
Described exterior sheathing and the area of inner formword are all greater than the area of reserved opening, enable exterior sheathing and inner formword by complete for reserved opening shutoff.
Owing to adopting technique scheme, the utility model has the advantage of: exterior sheathing of the present utility model and inner formword are fixed by the mutual drawknot of iron wire, therefore, do not set up the support of support shuttering in addition, not only time saving and energy saving, and save construction cost, substantially increase efficiency of construction.Meanwhile, it is simple, quick that the utility model also has installation, and whole formwork structure intensity is better, and after reserved opening shutoff is good, the exterior sheathing disassembled and inner formword can be reused, and saves construction material.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As shown in Figures 1 to 3, a kind of formwork structure for shutoff exterior wall reserved opening of the present utility model, comprise the exterior sheathing 2 and inner formword 5 that are arranged on reserved opening 8 both sides on exterior wall 1, described exterior sheathing 2 is the foldable templates adopting hinge 3 to connect and compose by two pieces of symmetrical templates, be provided with in inner formword 5 upper end and build mouth 6, four angles of exterior sheathing 2 and inner formword 5 arrange the first through hole 4 and the second through hole 7 respectively, and exterior sheathing 2 and inner formword 5 drawknot are fixed through after the first through hole 4 and the second through hole 7 by iron wire 9.Described exterior sheathing 2 and the area of inner formword 5 are all greater than the area of reserved opening 8, make exterior sheathing 2 and inner formword 5 can by reserved opening 8 shutoff completely.
During construction, first after one end of iron wire 9 being penetrated the first through hole 4 on exterior sheathing 2 four angles, binding is fixing, then close up folding for exterior sheathing 2 and pass reserved opening 8, now again exterior sheathing 2 is opened flattening, exterior sheathing 2 is made to be fitted in outside exterior wall 1, then the other end of iron wire 9 is penetrated the second through hole 7 on inner formword 5 four angles, make inner formword 5 be fitted in rear flank in exterior wall 1 iron wire 9 drawknot is fixed, exterior sheathing 2 and inner formword 5 is made tightly to be fitted in reserved opening 8 both sides, described exterior sheathing 2 and inner formword 5 are aluminum alloy mould plate, this template not only structural strength is better, and can use be had enough to meet the need after form removal, save construction cost.Finally by inner formword 5 builds mouth 6 to concreting in reserved opening 8, adopt microdilatancy pea gravel concreten when building reserved opening 8, utilize the expansion of microdilatancy pea gravel concreten to prevent reserved opening 8 from seeping water.Just exterior sheathing 2 and inner formword 5 can be removed after concrete setting, complete reserved opening 8 shutoff.
