Background technology
Assembled architecture refers to being built made of assemble in site with prefabricated component.The advantages of this building is to build speed
Degree is fast, and climate conditionality is small, saves labour and construction quality can be improved.Everyone can design by oneself and build certainly
Oneself house, wall can be dismantled repeatedly, and can reuse will not generate building waste due to demolishing walls.
But technically there is also two difficult points for existing assembled architecture, are on the one hand the firm time mistakes of conventional cement
It is long, it for, the lower assembled architecture of production cost fast for construction speed, can not match, need research and development to be suitble to fast
Dry cement matches.
On the other hand, due to that can carry out dismounting assembling between wall block, the concentrated position of the junction of wall block as stress, wall
Connection structure between block plays particularly important meaning to the security performance for improving building.The wall of existing assembled architecture
Block, since generally use bolt, screw connection or concreting are integrated at splicing seams.These schemes belong to just
Property connection, when meeting with the disasters such as earthquake, junction can not effectively discharge stress, lead to deformation of wall, even meeting when serious
There is the case where wall block breakage is collapsed, this has just buried huge security risk.
Invention content
The purpose of the present invention is to provide the efficient building methods of high intensity assembled architecture, not only improve assembled architecture
Prefabricated, assembly overall efficiency and the anti-seismic performance for effectively improving assembled architecture.
For achieving the above object, the technical solution adopted in the present invention is：The efficient structure of high intensity assembled architecture
It makes method, including dry wall block and wall is packaged matches, specifically comprises the following steps：
Process the reinforcing bar keel of dry wall block, and arrange on a side from reinforcing bar keel to wall block width direction side by side
The first reinforcing bar stretched out, multiple second reinforcing bars is stretched out to relative side, the height of the first and second reinforcing bars is straggly, water side by side
Prosposition is set respectively mutually from the center of wall block thickness；
Branch mold, casting concrete outside reinforcing bar keel make the first reinforcing bar and the second reinforcing bar be stretched out by the hole on mold, and
The pre-groove at the second reinforcing bar, concrete upper groove top have notch；
By opposite acute angle-shaped, the composition first bent in 30-60 ° of the first reinforcing bar and the second reinforcing bar difference after concrete hardening
Hook-type reinforcing bar and the second hook-type reinforcing bar, weld vertical reinforcement near hook-type root respectively；
Prefabricated wall block is arranged into building, adjacent wall block the first hook-type reinforcing bar is opposite with the second hook-type reinforcing bar, so
It supports in opposite directions afterwards so that the free end of the first and second hook-type reinforcing bars is stopped by vertical reinforcement and streaks after flexible deformation perpendicular respectively
To reinforcing bar, and the cooperation of " mutual " font is formed by vertical reinforcement non-return, and adjacent wall block is supported alignment；
From the notch on groove, into groove, casting concrete or filler are filled.
Preferably, when branch mold, asbestos pad first is set in the cell wall top surface of groove and the position of side wall internal upper part.
Preferably, when processing keel, attachment lug is respectively set in wall block bottom and top position, and respectively with steel
Muscle keel weld；It is pre-machined on the outside of attachment lug and wall block edge engaging portion with to the bending outstanding of wall block plate face, is connected
Connecting hole has been pre-machined on the outside of otic placode.
Preferably, when being assembled in building, adjacent wall block supports after alignment first with attachment lug and expansion bolt
Wall block is tentatively fixed.
The wall block of the present invention is when building is upper assembled, the first hook-type reinforcing bar and the second hook-type reinforcing bar on adjacent wall block
Although height is straggly, " mutual " font is constituted in groove because of the presence of vertical reinforcement and is interlocked, this phase is buckled in hook
The hook-type of shape reinforcing bar can not be unlocked in the case of not being destroyed, the length adaptation of the first hook-type reinforcing bar and the second hook-type reinforcing bar
It ensure that this interlock.Then by the notch on groove in groove casting concrete or stuffed heat insulated heat preservation filler, no
Connection reliability between wall block can only be further enhanced, improve mechanical property can shock resistance, wall block, assembled efficiency are all notable
It improves.The position that wall block is combined with constructional column, the first steel hook-type muscle go deep into constructional column, and the groove at the second hook-type reinforcing bar accommodates
Constructional column reinforcing bar gos deep into, and can pour connection together with constructional column, and the combination of constructional column is also closer, is very suitable for filling now
Technology trend and thinking cast-in-place with formula building beam column, wallboard is prefabricated.
Meanwhile normal concrete cannot exactly match the prefabricated demand of assembled wall block：Although existing quick hardening cement hardening
Time is short, but generally by its mechanical property is sacrificed as cost, and with the growth of time, quick hardening cement is compared with light water
Crack is more readily formed in mud, and overall performance is greatly reduced.In addition, being also frequently added tannic acid in quick hardening cement as efficient diminishing
Agent improves concrete flowability, reduces cement consumption to improve cement dispersibility.As publication No. is：Just it is situated between in 106750076A
The application to have continued using tannic acid as water-reducing agent in cement.But this kind of application to tannic acid can not increase quick hardening cement
Self-healing function and mechanical property.
Therefore the present invention improves concrete, obtains self-healing, quick-drying, strong concrete, including weigh as follows
Measure the following component of number：
Sulphate aluminium cement 34%~50%, flyash 25%~35%, high-efficiency water-reducing agent of poly-carboxylic acid 1%~2%, phenolic aldehyde
Resin 16%~25% chelates tannic acid 7%~14% after calcium ion, basic catalyst 1%~2%.
Self-healing, the preparation of quick-drying, strong concrete, include the following steps：
(1) 100mL saturations CaCl will be added at 25 DEG C per 10g tannic acid2In aqueous solution, waits for and precipitation is precipitated in solution
It is not further added by, the tannic acid of chelating calcium ion is obtained after filtering precipitation is dry；
(2) tannic acid for chelating calcium ion is added in phenolic resin starting material, basic catalyst K is added2CO3, stir mixed
It is warming up to 40 DEG C after even, reacts 1h；
(3) sulphate aluminium cement, flyash is added in above-mentioned product, high-efficiency water-reducing agent of poly-carboxylic acid is added after stirring and evenly mixing
Water is simultaneously sufficiently stirred, and has both been obtained with quick-drying, high intensity, the concrete of self-healing performance.
Above process 10g tannic acid and other reactants are proportionate relationship, and it is so mostly former not to be that every batch of is only capable of processing
Material.
The self-healing of the present invention, quick-drying, strong concrete have following advantage：
1, the intensity of cement is improved by the way that phenolic resin is added in cement, while phenolic resin cure delay at normal temperatures
Slowly, it is easy to form external hardened and internal also unhardened phenomenon, once there is crack generation, hardened layer rupture is unhardened
Part flowing mend a split after-hardening, self-healing can be played.
2, the present invention also utilizes the characteristic of phenolic resin, and the tannin for being chelated with a large amount of calcium ions is mixed into phenolic resin
Acid, after hardened layer rupture, the tannic acid for being chelated with calcium ion releases a large amount of calcium ions, generates calcium carbonate and is deposited, with phenol
Urea formaldehyde joint repairs the crack occurred, plays the effect that single phenolic resin repair mode is unable to reach.
3, the tannic acid itself for releasing calcium ion also belongs to a kind of phenols, can participate in forming a kind of phenol of stereochemical structure
Urea formaldehyde, fracture is repaired together with calcium ion.Better repairing effect has been not only acted as, tannin is also effectively utilized
Acid prevents unreacted component from remaining and wasting in the material.

Prefabricated wall block 10 is arranged into building, adjacent the first hook-type of wall block reinforcing bar 20 and 30 phase of the second hook-type reinforcing bar
It is right, then support in opposite directions so that the free end of the first and second hook-type reinforcing bars 20,30 respectively by vertical reinforcement 31,21 stop and
Streak vertical reinforcement 31,21 after flexible deformation, and by vertical reinforcement 31,21 non-returns and form the cooperation of " mutual " font, then will be adjacent
Wall block 10 supports alignment；From the notch 60 on groove, into groove, casting concrete or filler are filled.
Correspondingly, saying the core component wall block 10 of assembled architecture from the structure obtained, wall block 10 is plate-like, the wall
The plate face of block 10 is square, and wall block 10 is formed by concreting, and reinforcing bar keel 40 are arranged in inside concrete.It is described such as Fig. 1,2
10 right side of wall block is extended with multiple first hook-type reinforcing bars 20 side by side, and multiple second hook-type reinforcing bars 30, the first He are stretched out in left side side by side
Second hook-type reinforcing bar 20,30 is welded or is tied up with reinforcing bar keel 40 respectively and is integrated, prefabricated together to be process, and is usually processed
When hook-type reinforcing bar or straight, facilitate prefabricated processing, moment reinforcement is at hook-type reinforcing bar after concrete hardening.

First, second hook-type reinforcing bar 20,30 of block may make up " mutual " font in the groove and interlock, this interlocks by vertical reinforcement 21,31
Carry out non-return.
When assembly, although because the first hook-type reinforcing bar 20 and 30 position of the second hook-type reinforcing bar on adjacent wall block 10 are high
Low straggly and hook-type is opposite, and has the presence of vertical reinforcement 21,31, it is described as shown in Fig. 2, the wall block in left side move right when
It waits, the outer end of two hook-type reinforcing bars 20,30 will be stopped and elastic bending respectively by vertical reinforcement 31 and 21, continue hook-type reinforcing bar to the right
20, shape is restored in 30 outer ends after streaking vertical reinforcement 31,21, wants at this time if exiting the wall block 10 in left side to the left, vertically
Reinforcing bar 21,31 will stop hook-type reinforcing bar 30,20.Namely the first, second hook-type reinforcing bar 20,30 constitutes " mutual " word in groove
Shape interlocks, this phase be buckled in hook-type reinforcing bar 20,30 hook-type be not destroyed in the case of can not unlock.First hook-type
The hook-type angle of reinforcing bar 20 and the second hook-type reinforcing bar 30 between 30 °~60 °, such angle most beneficial for play hook-type most
The big power that interlocks.
In practice, the bent hookwise angle of different thicknesses reinforcing bar, hook-type reinforcing bar extension elongation needs are adaptively adjusted, to protect
Demonstrate,prove the length adaptation of the first hook-type reinforcing bar 20 and the second hook-type reinforcing bar 30.Length adaptation is also, for example,：Two hook-type reinforcing bars 20,30
Hook-type is symmetrical and is more than the thickness that depth of groove adds at least two or so reinforcing bar in the sum of extension elongation of wall block width direction, i.e.,
It can meet the requirements.
After reinforcing bar assembly in place, by the notch 60 on groove, casting concrete or stuffed heat insulated heat preservation are filled out in groove
