Abstract
The utility model relates to an expanded perlite circular hole wall insulating plate, which is in a rectangular shape. Full-length circular holes are arranged in the middle of the expanded perlite circular hole wall insulating plate along a length direction. A tenon and a groove are arranged on two long edges of the expanded perlite circular hole wall insulating plate. The expanded perlite circular hole wall insulating plate is characterized in that expanded perlite is used as a main material, and light burning powder, talcum powder, red foliage salt powder, and agglomerant are added to be mixed to form the expanded perlite circular hole wall insulating plate. Two layers of glass fibre threads are respectively laid on positions which are 5 millimeters away from the upper and the lower surface layers of the expanded perlite circular hole wall insulating plate. Cutting openings are respectively arranged on the four corners of the expanded perlite circular hole wall insulating plate. The volume weight of the expanded perlite circular hole wall insulating plate is only 750 kg/m+[3]. The expanded perlite circular hole wall insulating plate has the advantages of high intensity, corrosion protection, fire prevention, sound insulation, no deformation, etc. The expanded perlite circular hole wall insulating plate can be sawed, sliced, and nailed. The surface of the expanded perlite circular hole wall insulating plate can also be painted and stuck with face bricks and glazed bricks. The expanded perlite circular hole wall insulating plate is a novel building member which has low price and practicality.
Description
The utility model belongs to the building unit goods, is specially adapted to the goods of expanded perlite material.
At present, the partition board that general highrise building is used has cement board, magnesite plate and gypsum plank, the square type that is shaped as of plate, and circular hole is left in the centre, the fluted and tenon of the dual-side of plate.Though these plates all have the effect of building partition on function, the deficiency that exists some to use owing to employed material is different.Cement board is to be made by steel concrete, and unit weight is big, and heat insulating ability is poor, can not saw during installation, dig, and the reinforcing bar and the cement amount that use is bigger, and cost is than higher; The magnesite plate is by sawdust and magnesia mixing manufacture, and its water absorption rate height is yielding, and does not prevent fires, and is restricted in the use; Gypsum plank is low weight, but its cost is higher, and non-watertight, and the damage ratio during transportation is than higher.
The purpose of this utility model is to be that main material is made round-hole partition wall board with expanded perlite, the upper and lower two-layer intensity that respectively adds the layer of glass silk with reinforcement plate at plate, make this partition board except that satisfying Structural Design Requirement, also have lightweight, high-strength, sound insulation, fire prevention, indeformable advantage, and cost is lower.
Expanded perlite round-hole partition wall board of the present utility model is a rectangular slab, centre at plate is furnished with circular hole along its length, two long limits along plate have tenon and groove respectively, it is characterized in that: adopt expanded perlite and light burnt powder, French chalk, red leaf salt powder and cementing agent to mix and pour into the rectangular slab core, the layer of glass silk is respectively spread at 5 millimeters places of upper and lower surface layer at the distance plate, every layer glass fiber is 0.5% of a plate bulk ratio, in order to the intensity of reinforcement plate; Four jiaos of rabbets that respectively leave 2.5 * 27 millimeters on the plate two sides, sticking glass fiber silk ribbon is sewed in the connection that is used between the plate.
The volume ratio of expanded perlite material that round-hole partition wall board uses of the present utility model is: expanded perlite is 70～75%, and light burnt powder, French chalk, red leaf salt powder are 15～20%, cementing agent 5～9%.
The manufacturing process of expanded perlite round-hole partition wall board is: get expanded perlite and light burnt powder, French chalk, red leaf salt powder adding additives mixing stirring in proportion; The material that will stir is poured mould into then, pour 5 millimeters of one decks earlier into, completely spread the layer of glass silk by the length direction of member then, weight is 0.5% of component volume ratio, and then falls a layered material, floating, put into circular hole core pipe, continue batch turning again, tamp 3 millimeters on the upper strata of pipe, repave the layer of glass silk, again filler to template suitable for reading after, vibrate with the miniature plate vibrator, to increase the compactness of member, floating then, maintenance under+20 ℃ temperature is extracted circle core pipe out, form removal after five hours, after the maintenance 24 hours, intensity reaches 40% design strength, can be transported to deposit the plate place, sets level and transfers along sign indicating number together, carried out natural curing 15-20 days, and reached 100% of intensity.
Expanded perlite round-hole partition wall board of the present utility model, because the expanded perlite that adopts, the unit weight of member has only 750 kilograms/cubic metre, because upper and lower two-layer laying glass fiber at plate, make the compressive strength and the rupture strength of plate can both satisfy design strength, and have anticorrosion, fire prevention, sound insulation, advantage such as indeformable, and can saw, dig, follow closely, also can paint and whitewash on the surface, furring brick and ceramic tile, is a kind of inexpensive and practical building unit.
Below in conjunction with drawings and Examples expanded perlite round-hole partition wall board of the present utility model is further described.
Fig. 1 is the structure chart of expanded perlite round-hole partition wall board
Fig. 2 is the sectional drawing of Fig. 1
An existing round-hole partition wall board 1, be of a size of: 2500 * 600 * 60mm, aperture 40mm, there are tenon 4 and groove 5 in two long limits along plate, expanded perlite by 70%, 20% light burnt powder, French chalk, red leaf salt powder, 9% cementing agent, stir and make, cementing agent is 85% magnesium chloride and 15%107 glue; 2.5 * 27 millimeters rabbet 2 is left at four angles on member two sides, respectively spreads layer of glass silk 3 at 5 millimeters places of upper and lower surface layer of distance plate, and glass fiber is 1% of a plate bulk ratio.
