Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates to builing industry, particularly the board member of casting by the solidifiable composition.
Background of invention
The applicant notices, uses at present to be the cardboard box-shaped, waxing or the hollow mould of not waxing when construction of buildings basic.As for other, building trade is made cavity with wood and/or steel form and/or container is used for thereon or its in inject solidifiable composition to make board member with intended shape.
The applicant thinks, there are many shortcomings in above-mentioned art methods, comprising: the single of cardboard hollow mould uses, and wood and the required manpower and materials of steel form are provided, and is reaching the unified at interval difficulty aspect definite board member of template and/or hollow mould.Other problem comprises, for instance, is being that large span structure such as bridge are made the difficulty aspect the hollow mould, and provides framework required manpower and materials for the base portion of casting column and pillar and/or column and pillar.
A kind of typical building method adopts the steel hollow mould, this steel hollow mould has the structure of the pourable passage grid in wherein of definite solidifiable composition, the solidifiable composition is poured into a mould it then, forms a board member that alleviates, and reduces solidifiable composition consumption like this.A problem of this building method is, the steel hollow mould must be placed on the steel work, forms platform and definite passage, in case and board member form, these must be removed, this operation often relates to hand labor.The problem of removing hollow mould from the board member that forms can reduce by following way, is coated in hollow mould in advance towards solidifiable composition one side to unclamp composition such as oil that is:.
Therefore, according to a first aspect of the invention, provide a kind of hollow mould, this hollow mould has the chamber of being determined by one or more sidewalls, and at least one separator that extends laterally from the chamber, is used for the chamber of hollow mould is separated with contiguous thing.
General separator is spaced from each other the chamber of contiguous hollow mould, so that provide one group for the passage that injects the solidifiable composition when making the beam of board member and/or board member.
Separator can comprise can be from the chamber of hollow mould overhanging one or more fins.
In the use, the size of separator can be selected by the channel width that is fit to cast board member.
Hollow mould can have the insertion reinforcement, to strengthen the compression resistance of hollow mould.
