Abstract
A polyester fast demoulding combined mould for cement concrete hollow members in the building industry is composed of a mould frame 1 and a plurality of layers of combined mould cores 2 which are connected into a whole by bolts, wherein the end parts of the mould cores 2 are connected with mould core handles 3, and the mould core 2 is sleeved with a formed polyester isolation sleeve 4. The mould core is not contacted with the concrete surface layer, and a mould release agent is not needed any more. The member can be demoulded after casting, and the polyester spacer sleeve supports the member to be hollow by the strength of the member after the mold core is drawn out. The polyester sleeve can be used repeatedly. Use the utility model discloses can improve the component quality, improve work efficiency and output, reduce unit cost.
Description
The utility model relates to a kind of mould of making hollow cement components, belongs to the building mould field.
Traditional hollow cement components mould, core rod directly contacts with the concrete surface layer when making product.In order to be convenient in demoulding, require brushing releasing agent on core rod, be strict with simultaneously and after cast, rotate core rod frequently, in case solidify, and when member reaches initial set and is unlikely to subside, the demoulding at once, otherwise be difficult to the demoulding later on.Its drawback is: use a large amount of core rods, production capacity low; Releasing agent infiltrates in the member, and product strength reduction, breakage rate height, cost are strengthened; Demould time is long, work efficiency is low.
The purpose of this utility model provides a kind of releasing agent, short mould of demould time of not using.
The purpose of this utility model is achieved in that a kind of Cement Concrete hollow unit polyester fast demoulding assembling die is made up of multiple layer combination core rod framed, that link into an integrated entity with bolt, one end of core rod connects the core rod handle, and core rod is with the polyester separation sleeve of moulding.
Because core rod does not contact with the concrete surface layer, therefore no longer need to use releasing agent; Polyester separation sleeve itself has certain intensity in addition, and it is hollow that it can extract the back supporting member out at core rod, can shorten demould time like this, improve work efficiency.
Be further described below in conjunction with drawings and Examples.
Fig. 1 is a framed schematic diagram in the utility model;
Fig. 2 is a core rod structural map in the utility model.
Cement Concrete hollow unit polyester fast demoulding assembling die shown in the figure by framed 1, core rod 2, be enclosed within that high pressure mylar moulding separation sleeve 4 on the core rod 2 forms.Framed 1 usefulness angle bar is made, and framed end face plug is offered the core rod supported hole 5 that supports core rod 2; For adapting to the member of different size, core rod 2 adopts the multi-layer sheet combining form, and links into an integrated entity with bolt, and an end of core rod 2 connects core rod handle 3.During operation core rod 2 is put polyester separation sleeve 4, insert again in the core rod supported hole 5, pour into a mould then.After structure manufacture is finished, core rod can be extracted out, member is hollow to be kept not subsiding owing to there being polyester separation sleeve 4 to support.6 is the Cement Concrete hollow unit among the figure.
After adopting separation sleeve, core rod does not contact with the concrete surface layer, and the external surface area of core rod is corresponding reduces, so one side is according to the principle of " the big more absorption affinity of adsorption area is strong more ", the absorption affinity of core rod has reduced, and adds that the slickness of polyester is good, and core rod is extracted out easily when making the demoulding; On the other hand because of polyester hardness big, certain support force is arranged after the moulding, as long as the concrete material proportioning is suitable, after structure manufacture is finished, get final product the demoulding, thereby improve work efficiency; Polyester is treated to take out after the concrete body solidifies fully again, makes the concrete body not be subjected to any vibration to finish solidification process, does not re-use releasing agent simultaneously, and these all make component strength obviously strengthen.Polyester does not absorb water and does not shrink, and treats to be easy to after the concrete body solidifies fully to take out, and the polyester cover of extraction can use repeatedly.
Following test data can illustrate advantage of the present utility model: improve 5 times of work efficiency; Improve 6 times of output; Unit cost descends 12.6%.
Claims (1)
1, the multiple layer combination core rod (2) that links into an integrated entity by framed (1), with bolt of a kind of Cement Concrete hollow unit polyester fast demoulding assembling die is formed, one end of core rod (2) connects core rod handle (3), it is characterized in that core rod (2) is with the polyester separation sleeve (4) of moulding.
