On the contrary, the present invention contain any be defined by the claims the replacement done in the spirit and scope of the present invention, repair
Change, equivalent method and scheme.Further, in order to make the public that the present invention to be had a better understanding, thin to the present invention below
During joint describes, detailed describe some specific detail sections.There is no these detail sections for a person skilled in the art
Description can also understand the present invention completely.
[embodiment 1] as Figure 1-3, a kind of straw walling brick, described straw walling brick includes: the first brick body 1 and the
Two brick body 2, described first brick body 1 and described second brick body 2 are arranged symmetrically with composition v-shaped structure, described first brick body 1 and described
The core of two brick body 2 is the straw compacts of compacting, described straw compacts outer application waterproofing agent and fire retardant, it is ensured that straw
Brick will not cause because of core damage after using for a long time and subside.
The front end face of described first brick body 1 and described second brick body 2 and rear end face are identical parallelogram, institute
The acute angle stating parallelogram is more than 45 °, and less than 70 °, bottom brick body can be caused bigger pressure to cause brick body to support by angle too small
Situation about opening, the excessive restraining forces that necessity cannot be provided of angle, the long limit of described parallelogram with the ratio of minor face is: 1.5 ~ 2:
1, the minor face of the front and rear end of described first brick body 1 and described second brick body 2 contacts with each other, described first brick body 1 and described
The upper surface of two brick body 2 is v-depression, and the angle angle on described v-depression both sides is more than 120 °, less than 160 °, and angle too small
Bottom brick body can be caused the situation that bigger pressure causes brick body ftracture, described in the excessive restraining forces that necessity cannot be provided of angle the
The lower surface of one brick body 1 and described second brick body 2 is that V-arrangement is protruding, and the both sides angle of described V-arrangement projection is recessed with the V-arrangement of upper surface
Groove angle is identical, and the interval, one end that described first brick body 1 and described second brick body 2 contact arranges several first semicircle groove, institute
State the second brick body 2 and interval, one end that described first brick body 1 contacts arranges several first semi-circular projection, described first semicircle groove
Work in coordination with described first semi-circular projection.
[embodiment 2] as illustrated in figures 4-5, improves the first brick body 1 and bond strength of the second brick body 2 for further.This reality
Execute example essentially identical with above-described embodiment 1, only difference is that, described first brick body 1 and described second brick body 2 upper surface
V-depression both sides on be respectively provided with a second horizontal semicircle groove, described first brick body 1 and described second brick body 2 lower surface
V-arrangement exterior on be respectively provided with a second horizontal semi-circular projection, described second semicircle groove and described second semi-circular projection
Work in coordination.
[embodiment 3] as shown in fig. 6-7, improves the first brick body 1 and bond strength of the second brick body 2 for another step.This reality
Executing example essentially identical with above-described embodiment 2, only difference is that, contrary second brick body 2 one end of described first brick body 1 is arranged
Having spaced 3rd semi-circular projection, contrary first brick body 1 one end of described second brick body 2 is provided with the spaced 3rd half
Round recessed, described 3rd semicircle groove and described 3rd semi-circular projection are worked in coordination.
A kind of preparation method of straw walling brick, described method step is as follows:
S1: several straw one or any in corn stalk, soybean stalks, cotton stalk, wheat stalk is broken after drying
Broken for stalk fibre；
S2: stalk fibre is heated 60 minutes at a temperature of 100 DEG C；
S3: put into and be pressed into straw compacts in cuboid die cavity；
S4: straw compacts is soaked in fire retardant 30 minutes rear surface coating waterproofing agents；
S5: cement, firming agent, flyash, Gypsum Fibrosum, water are mixed according to following weight portion:
Cement: 50 ~ 60 parts, firming agent: 5 ~ 10 parts, flyash: 2 ~ 10 parts, Gypsum Fibrosum: 4 ~ 15 parts, water 20-25 part；
S6: the slurry that S5 mixes is placed in V-arrangement die cavity, and straw compacts is placed in pulp cores；
S7: matched moulds after compacting, takes out after slurry solidifies and stands 24 hours.
In use, first construct ground, and on ground, remain for arranging the V-shaped groove of body of wall in advance, by the first brick body and the
Two brick body form the installation foundation of body of wall in being positioned over V-shaped groove as one piece of full sized brick after combining, arranged successively by straw walling brick,
Due to straw walling brick be dual v-shaped structure, the most generally V-structure and upper surface be v-depression, lower surface is that V-arrangement is protruding,
The straw walling brick on upper strata is positioned at the dual v-shaped structure of the straw walling brick composition of lower floor, and its deadweight can maintain it at V-arrangement
Stability in groove, will not as traditional square brick is once pushing away, and each straw walling brick junction be equipped with semicircle groove with
Semi-circular projection, further enhances the fastness that each straw walling brick connects, and, it is straw compacts owing to brick body is internal,
Not only achieving the re-using of refuse, construction quality alleviates significantly, and brick body can also realize firmly without the biggest adhesion
Stable, after brick body has been arranged, stiff stability can be added further to adapt to the higher building using and requiring at surface-coated cement.
The straw walling brick of the present invention, it is possible to achieve fast construction simple construction thing or use require relatively low building or
Temporay building, and there is semicircle groove and the semi-circular projection setting of dual v-shaped structure conjunction junction, in conjunction with structure jail later
Gu stable, brick body self can realize enough bond strengths, and inner core is straw compacts simultaneously, is providing necessary support force
In the case of, significantly reduce the deadweight that building is overall.
