Abstract

The utility model relates to a mold used in building industry for making hollow precast member, which is composed of a movable bracket, a bottom mold, a side core mold, a plug and a side bearer. The movable bracket is provided with two cross beams, and each end of the cross beam is provided with a cross bar, and the bottom of the cross beam is provided with three rolling wheels. The overhead view shape of the plug is a convex plate whose lower end is provided with a gap, and the middle of the convex plate is provided with a hole whose size is bigger than that of the end plane of the core mold, and the core mold is inserted from the hole. The utility model has reasonable structure, and is convenient for disassembling and assembling; it is easy to demould, and is movable, thus is especially applied to produce longer hollow precast member with thin wall.

Description

Hollow concrete prefabricated member mould

The utility model relates to the mould of the hollow prefabricated component of the required making of building industry, particularly a kind of hollow magnesite concrete prefabricated member mould.

At present, make several meters long hollow concrete prefabricated component, particularly square hole, thin-walled is a difficult problem always.Reason is that prefabricated component early solidification intensity is low, must be through long time maintenance, but reach the just demoulding after certain intensity, thus make the mould life cycle long, the number of turnover is few, and utilization rate is low.When producing large scale prefabricated, not only will expend a large amount of moulds, and floor space is also very big.

The purpose of this utility model is a kind of removable, the pin-connected panel hollow concrete prefabricated component mould of designing at the problem of above-mentioned existence, but it only needs the just demoulding after the prefabricated component initial set, and can make long hollow, thin-walled prefabricated component.

The utility model is by movable supporting frame 1, bed die 3, side form 6, core 7, plug 9, bogie side frame 10 and depression bar 11 are formed, two crossbeams 2 are arranged on movable supporting frame 1, respectively there is a cross bar 12 at two ends, both sides are provided with at least two group bogie side frames 10,3 rollers 16 are arranged at the bottom, plug 9 plan view shapes are one " protruding " shape plate, there is the hole 25 more bigger than core 7 face sizes the centre, this hole is the fillet square hole, the lower end also has at least two breach 17, both sides are provided with several apertures 23, the two ends of bed die 3 are respectively equipped with at least two reference columns 13, cooperate with the breach 17 on the plug 9, side form 6 two ends have several apertures 24, and are corresponding with the aperture 23 on the plug 9, connect with U-shaped card 14, at bed die 3, side form 6, be compounded with separable soft springform 4 and Membrane cover 8 that one deck is made of materials such as rubber on the core 7, be placed with base 5 on the crossbeam 2, have several breach 15 to cooperate on the cross bar 12 with reference column 13 on the bed die 3.

The utility model is rational in infrastructure, the dismounting combined and instant, and the demoulding is easy, and removable, is specially adapted to make long hollow, thin-walled prefabricated component.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the side view of Fig. 1;

Fig. 4 is the enlarged drawing of I portion among Fig. 1;

Fig. 5 is the upward view of Fig. 4.

1-movable supporting frame among the figure, 2-crossbeam, 3-bed die, 4-elastic membrane, 5-base, the 6-side form, 7-core, 8-elasticity Membrane cover, 9-plug, the 10-bogie side frame, 11-depression bar, 12-cross bar, 13-reference column, 14-U type card, 15-cross bar breach, 16-roller, 17-plug breach, 18-base extending area, the 19-backstay, the 20-set bolt, 21-regulates bolt, 22-base two stomidiums, 23-plug both sides aperture, 24-side form two ends aperture, 25-plug interstitial hole.

There is the one side of soft elastic membrane upwards to be placed on the movable supporting frame 1 bed die 3, the reference column 13 at bed die 3 two ends is put into the breach 15 of cross bar 12, at this moment the weight on the bed die 3 acts on the crossbeam 2 by base 5, movable supporting frame 1 can guarantee mould not torsional buckling distortion when mobile, then on the corresponding reference column 13 that inserts between bed die 3 two ends and the cross bar 12 of breach with plug 9 lower ends, the lower limb of the projecting surface of plug 9 is pressed on the top edge of bed die end face, at this moment there is two side forms 6 one side of soft elastic membrane to be placed on relatively on the extending area, base 5 both sides 18, two ends connect with plug 9 both sides with U type card 14, again several groups of bogie side frames 10 are put well on movable supporting frame 1, fix with set bolt 20 after bolt 21 is adjusted the position with regulating, give side form 6 export-oriented location.Then mixed concrete is injected in the mould that combines according to quantity pave, ram-jolt.Again core 7 is coated surface lubricant and put soft elasticity Membrane cover 8, from the interstitial hole 25 of plug 9, insert mould, regulate the gap of core both sides, on bogie side frame 10, load onto depression bar 11 again and make backstay 19 push down core, core 7 is positioned.At this moment inject concrete to the space of entire die and also take off depression bar 11 after vibrations, the tamping, the surface is pressed the height of side form 6 and receive flat.Entire die can be moved to simultaneously and wait for initial set between maintenance.After treating initial set, core 7 is extracted, made soft elasticity Membrane cover separate and pull out again from the prefabricated component endoporus with specific purpose tool.Again bogie side frame 10 is taken off, unclamp U type card 14, side form 6 is separated with soft elastic membrane, take soft elastic membrane 4 off, bed die 3 sling to be placed on together with the prefabricated component of sloughing core, side form at 5 liang of stomidium 22 positions of base with crane gear and continue maintenance on the shelf.Core, side form, bogie side frame and movable supporting frame can work on after mixing standby bed die, pour into a mould next prefabricated component.Significantly reduced the mould occupancy like this, and floor space is few.
