The present invention's production procedure is specifically:
Step 1, mould rod manufactures:
First do mould rod post 12 as requested, one end open is connected with source of the gas, and outside openend, silk rolling 10-300mm is long, and in openend, an annular groove is done at 10-300mm place, the other end makes ball shape, bores Φ 1-6mm air-vent 14 respectively in ball shape end distance groove 5-20mm section, 5-30 order grid sleeve 11 is loaded onto outside mould rod post 12, grid sleeve 11 length flushes with pylon face, the exterior ventilative sponge sleeve 10 of grid sleeve, sponge sleeve 10 diameter meets designing requirement, sponge sleeve 10 length and grid sleeve 11 are with long, sponge sleeve 10 outer suit rubber bush 9, rubber bush 9 length exceedes annular groove 3-50mm, jump ring 18 is sealed outer installation of rubber bush 9, make rubber snap in annular groove and mould rod post airtight, mould rod post connects source of the gas through mould rod post blow vent 15, inflation pressure testing, keep pressure 4 hours unchanged qualified, mould rod completes.
Step 2, Making mold:
According to the length, width and height of building block; according to permutation and combination perforate on die bottom plate 20 and mould rod post fixed head 19 of honeycomb, mould rod hole 31 is concentric with mould rod fixing hole 30, and mould rod fixing hole 30 diameter is identical with the canned paragraph of mould rod post 12; mould rod 8 is inserted mold fixed plate hole fix; source of the gas connects all air inlets, and fixed mould completes, and die bottom plate 20 and die side plate 21 have been assembled; open air compressor to the inflation of mould rod; mould rod diameter reaches requirement, and voltage stabilizing is shut down, and Mold Making completes.
Step 3, building block are built:
Stirred by the materials such as sand, stone, cement, water according to block designs intensity proportioning, be poured in mould, vibrations, keep 0.5-30mm thickness above top, mould baseball face and concrete, floating, leave standstill and solidify.
Step 4, demoulding maintenance, finished product:
After solidifying 0.5-24 hour, close gas check valve, open vent valve, gas in release mould rod, mould rod is separated with concrete, closes vent valve, opens vavuum pump, open vacuum valve, vacuum reaches 0.01-0.04pa, and mould rod shrinks further, and move moulds fixed head or mould exit mould rod, maintenance terminates to making the phase, namely forms honeycomb like building block finished product.
After mould rod of the present invention connects source of the gas, its diameter and length can expand along with the change of excellent capsule internal gas pressure intensity and shrink, mould rod barred body after concrete setting shrinks and exits smoothly, and the honeycomb cavity wall of formation is intact, namely forms smooth outer surface after moving back mould, inside is the building block of honeycomb like, building block unit weight is low, intensity is high, waterproof, good heat insulation, and cost is low, easy construction, once construction can complete twice construction of prior art, reduces expenses of labour.Prior art all completely can not exit mould after the concrete has set, more can not produce honeycomb like product.
Mould frame can form plurality of specifications size as required, and mould rod can Reusability, can mechanization large-scale production.
The building blocks such as the alternative building maintenance of building block of the present invention cement brick used, cement block, common brick, foam cement are built soon, exterior wall aerated bricks, also can be used for square ecological floor tile, pavement, community, soundproof wall, roofing insulation etc., wide market.
Mould rod of the present invention is also applicable to the field such as equipment base concrete preformed hole, disaster relief support, voiceless demolition of various model.
