Two brick bodies 2, first brick body 1 and second brick body 2 are arranged symmetrically composition v-shaped structure, first brick body 1 and described
The core of two brick bodies 2 is the stalk pressing entity of compacting, the stalk pressing entity outer application waterproofing agent and fire retardant, it is ensured that stalk
Brick will not cause to collapse after using long-time because of core damage.
The front end face of first brick body 1 and second brick body 2 and rear end face are identical parallelogram, institute
The acute angle for stating parallelogram is greater than 45 °, and less than 70 °, angle too small can cause larger pressure that brick body is caused to support to bottom brick body
The case where opening, angle is excessive can not to provide necessary restraining force, the ratio between the long side of the parallelogram and short side are as follows: 1.5 ~ 2:
1, the short side of the front and rear end of first brick body 1 and second brick body 2 contacts with each other, first brick body 1 and described
The upper surface of two brick bodies 2 is v-depression, and the included angle on the v-depression both sides is greater than 120 °, less than 160 °, angle too small
Can the case where causing larger pressure that brick body is caused to crack bottom brick body, angle is excessive can not to provide described in necessary restraining force the
The lower end surface of one brick body 1 and second brick body 2 is V-arrangement protrusion, and the both sides angle of the V-arrangement protrusion and the V-arrangement of upper surface are recessed
Slot angle is identical, and several first semicircle grooves, institute is arranged in one end interval that first brick body 1 is contacted with second brick body 2
It states one end interval that the second brick body 2 is contacted with first brick body 1 and several first semi-circular projections, first semicircle groove is set
It works in coordination with first semi-circular projection.
[embodiment 2] as illustrated in figures 4-5, for the bond strength for further increasing the first brick body 1 and the second brick body 2.This reality
It applies example and above-described embodiment 1 is essentially identical, only difference is that, first brick body 1 and 2 upper surface of the second brick body
V-depression both sides on be respectively provided with a second lateral semicircle groove, first brick body 1 and 2 lower end surface of the second brick body
V-arrangement exterior on be respectively provided with a second lateral semi-circular projection, second semicircle groove and second semi-circular projection
It works in coordination.
[embodiment 3] as shown in fig. 6-7, the bond strength of the first brick body 1 and the second brick body 2 is improved for another step.This reality
It applies example and above-described embodiment 2 is essentially identical, only difference is that, the setting of first brick body 1 opposite second brick body, 2 one end
There is spaced third semi-circular projection, opposite first brick body, 1 one end of second brick body 2 is provided with spaced third half
Round recessed, the third semicircle groove and the third semi-circular projection are worked in coordination.
A kind of preparation method of stalk walling brick, the method comprises the following steps:
S1: several stalk one or any in corn stalk, soybean stalks, cotton stalk, wheat stalk is dry
After be broken for stalk fibre；
S2: by stalk fibre 100 DEG C at a temperature of heat 60 minutes；
S3: it is put into cuboid die cavity and is pressed into stalk pressing entity；
S4: stalk pressing entity is impregnated to 30 minutes rear surface coating waterproofing agents in fire retardant；
S5: cement, curing agent, flyash, gypsum, water are mixed according to following parts by weight:
Cement: 50 ~ 60 parts, curing agent: 5 ~ 10 parts, flyash: 2 ~ 10 parts, gypsum: 4 ~ 15 parts, 20-25 parts of water；
S6: the S5 slurry mixed is placed into V-arrangement die cavity, and stalk pressing entity is placed in pulp cores；
S7: molding after compacting, takes out after slurry solidification and stands 24 hours.
When in use, ground is first constructed, and remains on ground the V-shaped groove that wall is set in advance, by the first brick body and the
Two brick bodies are placed in the installation foundation that wall is formed in V-shaped groove as one piece of full sized brick after combining, and stalk walling brick is successively arranged,
Since stalk walling brick is dual v-shaped structure, i.e., generally V-structure and upper surface are v-depression, and lower end surface is V-arrangement protrusion,
The stalk walling brick on upper layer is located in the dual v-shaped structure of stalk walling brick composition of lower layer, and self weight can maintain it in V-arrangement
Stability in slot, will not as traditional square brick is once pushing away, and each stalk walling brick junction be equipped with semicircle groove with
Semi-circular projection further enhances the fastness of each stalk walling brick connection, also, due to being stalk pressing entity inside brick body,
The re-using of waste is not only realized, construction quality mitigates significantly, and brick body also may be implemented securely without very big binding force
Stablize, after the completion of brick body arrangement, cement can be coated on surface and further strengthen stability to adapt to the building of higher requirement.
Stalk walling brick of the invention, may be implemented fast construction simple construction object or the lower building of requirement or
Temporay building, and the semicircle groove with dual v-shaped structure conjunction junction and semi-circular projection are arranged, in conjunction with later structure jail
Gu stablizing, enough bond strengths are can be realized in brick body itself, while inner core is stalk pressing entity, are providing necessary support force
In the case of, significantly reduce the whole self weight of building.
