Detailed description of the invention
Structural schematic diagram of the Fig. 1 as a preferred embodiment of building foundation plate of the invention.
Description of symbols:
1 plate；2 glass fiber reticular cloths.
Specific embodiment
The technical solution of the building foundation plate is described in detail below with reference to Fig. 1:
Embodiment 1:
A kind of building foundation plate, including plate 1 and glass fiber reticular cloth 2, glass fiber reticular cloth 2 are separately positioned on 1 surface two of plate
The state of being bonded to each other is formed by surface and is arranged to by side in state is bonded to each other between plate 1 and glass fiber reticular cloth 2
Half flat half numb structure.Described half flat half numb structure use by the setting of glass fiber reticular cloth 2 along 1 surface of plate to inside plate 1 away from
At its mid-depth 0.01mm to the position 2mm, wherein the part of 1 surface 5%-70% of plate is exposed glass fiber reticular cloth 2,
The other two sides of fiberglass mesh tow of exposed glass fiber reticular cloth 2 and bottom are surrounded by plate 1, and top is glass fiber reticular cloth
The glass tow of 2 exposed face, remaining 30% to 95% not exposed glass fiber reticular cloth 2 is then wrapped in plate 1 completely
Portion and at its surface 0.01mm to the position 2mm.Glass fiber reticular cloth 2 is substituted by fibre bundle or wire bundle, the tow
Using monofilament or synnema.The water ash weight ratio of mortar is greater than 0.5-0.6:1 in plate 1, including water-reducing agent, such as containing quartz
The weight that sand is then free of quartz sand in the water ash weight ratio then excludes plant fiber itself such as containing sawdust plant fiber
The slurry of the moisture accounting absorbed, production plate 1 uses atherosclerotic or dilute cream shape, the mortar in plate 1 if not including water-reducing agent
Water ash weight ratio be greater than 0.7:1.The molding of the building foundation plate uses upper and lower belt roll-forming.
The building foundation plate is through the belt roll-forming up and down, and the heat release in belt of subsequent mortar forms 1-
After five minutes, the technology relatively low using the glass tow surface plaster intensity under upper and lower forming belt and the completed state
Feature is glued the plate mortar bed of glass tow surface 0.01-2mm from plate surface using upper and lower forming belt, to expose
Glass tow, to form the half flat half numb structure on 1 surface of plate.Wherein, water ash weight ratio is bigger, and solidified forming time is got over
Long, the exposed accounting of glass tow can be lower, conversely, water ash weight ratio is smaller, solidified forming time is relatively short, then glass tow
Exposed accounting is bigger.The exposed accounting of glass tow is not the bigger the better nor the smaller the better.As glass tow is exposed
Accounting is bigger, then the flexural strength of plate also can be reduced accordingly, and if the exposed accounting of glass tow is too small, plate surface is for outer
The adhesive force for adoring layer also can be lower, and in plate stress, plate surface will appear the subtle slight crack at glass, influence beauty, by force
Degree performance will not be brought into play completely.By repeatedly it is demonstrated experimentally that the exposed area accounting of glass tow is advisable with 30-50%.
Embodiment 2:
A kind of building foundation plate, including plate 1 and glass fiber reticular cloth 2, glass fiber reticular cloth 2 are separately positioned on 1 surface two of plate
The state of being bonded to each other is formed by surface and is arranged to by side in state is bonded to each other between plate 1 and glass fiber reticular cloth 2
Half flat half numb structure.Described half flat half numb structure use by the setting of glass fiber reticular cloth 2 along 1 surface of plate to inside plate 1 away from
At its mid-depth 0.01mm to the position 1mm, 2 one side surface of glass fiber reticular cloth all 100% exposes to 1 surface of plate, exposed
Glass fiber reticular cloth 2 the other two sides of fiberglass mesh tow and bottom surrounded by 1 raw material of plate, the top of glass fiber reticular cloth 2
All 100% is exposed face.Glass fiber reticular cloth 2 is substituted by fibre bundle or wire bundle, and the tow uses monofilament or synnema.
The water ash weight ratio of mortar is 0.3-0.5:1 in plate 1, and including water-reducing agent, water ash weight ratio is if without water-reducing agent
0.4-0.5:1 is free of the weight of quartz sand in the ratio of mud if containing quartz sand, such as contains sawdust plant fiber, then excludes
The moisture accounting that plant fiber itself is absorbed, production plate stirring material be it is fluffy, can hold and hold molding.The building foundation
The molding of plate uses extrusion forming or extrusion under vacuum.
The extrusion forming is that extrusion molding dies are arranged to be fed together glass in plate plane two sides, and with pressing material
Grid cloth, at the plate glass fiber reticular cloth enhancement layer squeezed out away from plate surface at plate thickness central interior 0.01-1mm, but
The glass tow of all outer Roses in plate surface glass fiber reticular cloth side, exposed glass fiber reticular cloth are wrapped by 3 side of building board material
It encloses, it is naked outside side (outer surface)；Plate surface forms the form of half flat half fiber crops, which need to be impregnation glass.Fiber filament
Beam diameter is bigger, and plate flexural strength is better.It the glass tow two sides of exposed glass fiber reticular cloth even can be with by building board material
It forms fibre bundle surface 75% to surround, flexural strength greatly improves.
Embodiment 3:
A kind of building foundation plate, including plate 1 and glass fiber reticular cloth 2, glass fiber reticular cloth 2 are separately positioned on 1 surface two of plate
Side, in being bonded to each other state between plate 1 and glass fiber reticular cloth 2, the setting of glass fiber reticular cloth 2 along 1 surface of plate into plate 1
Portion is apart from its mid-depth 0.01mm to the position 2mm, and the 100% of glass fiber reticular cloth 2 is all filled in 1 liang of end surfaces of plate
It is internal.Glass fiber reticular cloth 2 is substituted by fibre bundle or wire bundle, and the tow uses monofilament or synnema.Mortar in plate 1
Water ash weight ratio is greater than 0.5-0.6:1, including water-reducing agent, without quartz in water ash weight ratio as described in if containing quartz sand
The weight of sand, such as contain sawdust plant fiber, then the moisture accounting that plant fiber itself is absorbed is excluded, production plate 1
Slurry uses atherosclerotic or dilute cream shape, and the water ash weight ratio of mortar is greater than 0.7:1 in plate 1 if not including water-reducing agent, described to build
Basic plate is built using roll-forming.
The building foundation plate is through the belt roll-forming up and down, and the heat release in belt of subsequent mortar forms 3-
After ten minutes, board making forms, and since mortar is than relatively large, glass fiber reticular cloth is bonded completely in plate two sides appearance
At the inward-facing position 0.01-2mm.This kind of form is best for the flexural strength of plate, but in plate bending deformation,
Plate surface can generate certain slight crack.
The various embodiments described above are only preferred technical solution, involved in each building block and connection relationship simultaneously
Embodiment described in being not limited to the above embodiments, the setting and connection of each building block in above-mentioned preferred embodiment
Relationship can carry out arbitrary permutation and combination and form complete technical solution.
