Abstract
The invention discloses a manufacture method for a honeycomb aerated concrete energy-absorption brick. The manufacture method includes the steps: a die the top part of which is provided with a cut and the two corresponding side surfaces of which are provided with a plurality of layers; besides, each layer is provided with a plurality of holes; a hollow plastic tube is inserted into each hole or alternative hole at one side of a bottom layer to the hole on the opposite surface; then the upper surface of the hollow plastic tube is paved with a layer of geogrids; in the same way, after the hollow plastic tube is upwards inserted in turn into the hole of each layer, a layer of geogrids is then paved on the upper surface of the hollow tube; aerated concretes are cast into the bottom part of the die from the top part; the aerated concretes are solidified and then demoulded. The invention can effectively absorb the collision energy by plastic deformation, has simple structure and low cost and is suitable for the collision protection of structures with equal sections and variable sections.
Description
Technical field
The present invention relates to works Anti-bumping protection member, relate in particular to a kind of preparation method of honeycomb-shaped air-entrained concrete energy-absorbing brick.
Background technology
Contact adhesion type CAS is extensively adopted in the crashproof measure of existing structure, is mainly made up by steel or concrete and forms.The steel CAS involves great expense, and conventional concrete construction is very easily broken under the impact effect, and crashproof ability is lower.
Summary of the invention
The object of the present invention is to provide cost of manufacture low, corrosion-resistant, anti-aging, change convenient, a kind of honeycomb-shaped air-entrained concrete energy-absorbing brick that crashproof ability is strong.
The step of the technical solution used in the present invention is as follows:
1) adopt open top, two corresponding side surface to have multilayer and every layer of mould that is evenly equipped with a plurality of holes, from mold bottom, insert hollow plastic tube in each hole of bottom one side or in the alternate hole in to face, on hollow plastic tube, lay one deck GSZ again, in like manner, after upwards inserting hollow plastic tube in every layer hole successively, lay one deck GSZ again on hollow plastic tube, its number of plies and every layer of hole count are decided according to the design needs;
2) from the mould top to bottom pouring air entrained concrete, the demoulding after air entrained concrete solidifies.
Described air entrained concrete is made by cement, aglite and air-entrainment, 1m
3Percent by volume between the cement that air entrained concrete adopts, water, aglite, the air-entrainment is 20～25%: 12～20%: 55～65%: 0.05～0.065%.
Described aglite is perlite or haydite; Air-entrainment is AEA or rosin soap class air entraining agent.
Described bilevel hollow plastic tube is arranged in juxtaposition or alternate layout.
Described mould is cube, cuboid or cylinder.
The beneficial effect that the present invention has is:
The present invention can absorb collision energy by plastic deformation effectively, and simple in structure, cost is low, is applicable to the Anti-bumping protection of uiform section or variable section structure thing.

The specific embodiment
As Fig. 4, shown in Figure 3, the present invention adopts open top, two corresponding side surface to have multilayer and every layer of mould 5 that is evenly equipped with a plurality of holes 6, from mould 5 bottoms, insert hollow plastic tube in each hole 6 of bottom one side or in the alternate hole 6 in to face, on hollow plastic tube, lay one deck GSZ 3 again, in like manner, after upwards in every layer hole, inserting hollow plastic tube successively, lay one deck GSZ 3 again on hollow plastic tube, its number of plies and every layer of hole count are decided according to the design needs.
As shown in Figure 1, from the mould top to bottom pouring air entrained concrete, the demoulding after air entrained concrete solidifies, honeycomb-shaped air-entrained concrete energy-absorbing brick, Fig. 2 is the top plan view of the honeycomb-shaped air-entrained concrete energy-absorbing brick of Fig. 1.
Described air entrained concrete is made by cement, aglite and air-entrainment, and honeycomb-shaped air-entrained concrete energy-absorbing brick can reach different intensity and appearance and size by the ratio of mud of change air entrained concrete 1 and the size of mesh opening of aggregate match ratio, GSZ 3.
Described aglite is perlite or haydite; Air-entrainment is AEA or rosin soap class air entraining agent.
Described bilevel hollow plastic tube is arranged in juxtaposition or alternate layout, and two-layer up and down among Fig. 1 is alternate layout.
Described mould is cube, cuboid or cylinder.
Embodiment 1:1m
3Between the cement that air entrained concrete adopts, water, perlite, the AEA percent by volume be: 21%: 14%: 64.95%: 0.05%.
Embodiment 2:1m
3Percent by volume between the cement that air entrained concrete adopts, water, haydite, the rosin soap class air entraining agent is: 23%: 17%: 59.42%: 0.058%.
Embodiment 3:1m
3Percent by volume between the cement that air entrained concrete adopts, water, perlite, the AEA is: 25%: 19%: 55.935%: 0.065%.
When honeycomb-shaped air-entrained concrete energy-absorbing brick is subjected to impact 4 effect compressions, GSZ 3 has retrained carrying out of air entrained concrete 1 vertical microcrack and can resist the shear stress that produces in the honeycomb-shaped air-entrained concrete energy-absorbing brick, make honeycomb-shaped air-entrained concrete energy-absorbing brick keep bulk deformation, unlikely cracked too early.
Crashproof effect of the present invention is achieved in that
Honeycomb-shaped air-entrained concrete energy-absorbing brick provided by the invention is made up of the GSZ 3 vertical with crash direction that honeycomb fashion air entrained concrete 1 and place Min layers are located at wherein.When the present invention is subjected to clashing into, space in the air entrained concrete 1 and honeycomb structure 2 all can be compressed, GSZ 3 has retrained carrying out of vertical microcrack and can resist the shear stress that produces in the honeycomb-shaped air-entrained concrete energy-absorbing brick simultaneously, absorb a large amount of impact energys, the damage of having avoided being hit works by plastic deformation of the present invention.
