Abstract
Disclosed is a mountable and withdrawable bottom die structure of cast-in-place stairs construction joints, which belongs to the technical field of bottom die structures of cast-in-place stairs construction joints. The technical scheme comprises steps of setting up a stairs supporter by vertical and transverse steel tubes, placing a square timber on the supporter, arranging the lower end of the square timber tightly against the ground, and sequentially arranging a lower bottom die, a mountable and withdrawable bottom die and an upper die on the square timber. The utility model is improved basing on the conventional structure and changes the original one integral bottom die into three bottom dies, and further the bottom dies at the construction joint are mountable and withdrawable, and when cleaning the construction joint, by withdrawing the mountable and withdrawable bottom dies, and washing sundries at the construction joint, then the sundries can flow out of a cavity along with flowing water, wherein the cavity is formed after withdrawing the mountable and withdrawable bottom dies. After cleaning up, the mountable and withdrawable bottom die can be remounted for pouring the upper 2/3 stairs. The mountable and withdrawable bottom die is simple in structure, and the sundries are easy to clean at the construction joint position, thereby avoiding slag inclusion and increasing construction efficiency and engineering quality.
Description
Technical field
The utility model belongs to the technical field of cast-in-place stair constuction joint bed die structure, and the bed die that is specifically related to a kind of constuction joint place can be adorned the bed die structure that can take out.
Background technology
When cast-in-place stair tread is constructed, all will be at the stressed minimum place of bench, promptly 1/3 place of bench is provided with constuction joint.In traditional work progress, the bed die of the bench of will constructing earlier all lays, and builds 1/3 bench of below earlier, then remaining 2/3 bench above building.Before the stair of building back 2/3 part, want earlier hair to be cut a hole at the constuction joint position, and garbage-cleaning is clean.But because bed die all fixedly lays, make the foreign material at constuction joint position be difficult to cleaning like this,, do not reach engineering objective and do over again again if the slag inclusion phenomenon do not occur after cleaning totally then can not cause constuction joint position concreting, increase unnecessary workload, improved building costs.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of cast-in-place stair constuction joint can adorn the technical scheme of drawable type bed die structure, is convenient to clean the foreign material at constuction joint position, improves workmanship.
Described cast-in-place stair constuction joint can be adorned drawable type bed die structure, it is characterized in that setting up the stair bracing frame by vertical steel pipe, horizontal steel pipe, the lumps of wood is placed on the bracing frame, and firm ground is pushed up in lumps of wood bottom, in proper order bed die is set down successively on the lumps of wood, can adorns and can take out bed die, last bed die.
Described cast-in-place stair constuction joint can be adorned drawable type bed die structure, it is characterized in that descending bed die, last bed die to fixedly connected with the lumps of wood, can adorn and can take out bed die and lumps of wood flexible connection.
Described cast-in-place stair constuction joint can be adorned drawable type bed die structure, it is characterized in that adorning and can take out 1/3 place that bed die is arranged on stair.
Described cast-in-place stair constuction joint can be adorned drawable type bed die structure, and it is characterized in that adorning the width that can take out bed die is 95～105mm.
Described cast-in-place stair constuction joint can be adorned drawable type bed die structure, it is characterized in that the width of following bed die, last bed die is determined by the stair chamfer length.
The utility model is improved on conventional architectures, change an original monoblock bed die into three bed dies, and the bed die at constuction joint position can be adorned and can take out, in the time will clearing up to the constuction joint position, can adorn and to take out the bed die extraction, the foreign material at water flushing this moment constuction joint place, foreign material can flow out from extracting out can adorn can take out the cavity that forms behind the bed die with current.Can adorn after having cleared up and to take out bed die and reinstall and to carry out top the building of 2/3 stair.The utility model is simple in structure, is convenient to cleaning for the foreign material at constuction joint position, has avoided the appearance of slag inclusion phenomenon, has improved efficiency of construction and workmanship.

The specific embodiment
At first according to designing requirement and bench size, set up the stair bracing frame by vertical steel pipe 3, horizontal steel pipe 4, the lumps of wood 2 is placed on the bracing frame, firm ground is pushed up in the lumps of wood 2 bottoms, guarantees that the lumps of wood 2 can not be offset in the process of building.On the lumps of wood 2 successively order bed die 1 is set down, can adorn can take out bed die 1a, on bed die 1b, following bed die 1, go up bed die 1b and fixedly connected with the lumps of wood 2, generally adopt nail, make its fixation.Can adorn and can take out bed die 1a and the lumps of wood 2 and flexibly connect, from the side of the lumps of wood 2 nail be hammered into to adorn and can take out the bed die 1a, reserve one section at the nail tail end, assurance can be opened out nail.Can adorn and can take out 1/3 place that bed die 1a is arranged on stair, width is 100～110mm, and preferred value is 100mm.The width of following bed die 1, last bed die 1b is determined by the stair chamfer length.
Earlier with the stair of below 1/3 bench, promptly the following bench of constuction joint with concreting good after, with the fixing lumps of wood 2 with can adorn the nail that can take out bed die 1a and open out, extraction can be adorned and can take out bed die 1a, placement one side, travel direction sign back.After constuction joint cut a hole hair, rubbish is cleaned back water flushing, this moment, foreign material just can flow out from extracting out can adorn can take out the cavity that forms behind the bed die with current.Can adorn after having cleared up and to take out bed die 1a and be installed on the lumps of wood 2, and nail be hammered into to adorn at side and can take out the bed die 1a from the lumps of wood 2.And then the stair of top 2/3 bench are built.
In highrise building, to following bed die 1, can adorn can take out bed die 1a, go up bed die 1b and identify after, can build middle recycling at the stair of typical floor, saved cost.
