Description
Technical field
The present invention relates to building construction fields, more particularly, to a kind of sound insulation wall construction method.
Background technique
Partition-type structures of the wall as building, are the important components of building.
Wall generally uses reinforced concrete wall, in earthquake, since concrete is rigid material, after shattering, breaks
It is broken into bulk and pounds to fall and hurt sb.'s feelings, cause people during escape, be easy to be influenced by pounding the concrete block fallen, so that escaping
Raw probability decline, therefore there are also improve space.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of sound insulation wall construction method, has ground
The advantages of influencing people's escape is not easy when shake.
To achieve the above object, the present invention provides the following technical scheme that
A kind of sound insulation wall construction method, comprising the following steps:
S1. steel reinforcement cage is built；
S2., cast template is installed for the first time；
S3. concrete is poured to form concrete wall；
S4. cast template is dismantled for the first time, specific as follows:
Cast template is dismantled after concrete wall initial set；
S5. asphalt surface course is coated, specific as follows:
Asphalt is coated on the metope of concrete wall after initial set forms asphalt surface course；
S6. secondary installing cast template, specific as follows:
Cast template is supported by bracket, there are spacing for cast template and asphalt surface course；
S7. asphalt surface course is poured concrete, specific as follows:
It is concordant at the top of wall to concrete that it is poured concrete in towards cast template, stands 20-40min, is poured again
Concrete is so that concrete top is concordant at the top of wall, and after standing 60-90min again, casting concrete is so that coagulation again
Native top is concordant at the top of wall；
S8. two disassembly cast templates, specific as follows:
Asphalt concrete pavement is formed after the concrete initial set being poured for the last time in S7, dismantles cast template；
S9. paving sound-absorbing material, specific as follows:
In asphalt concrete pavement surface paving sound-absorbing material；
S10. putty layer is coated, specific as follows:
Putty layer is coated on asphalt concrete pavement.
By using above-mentioned technical proposal, asphalt surface course is coated on concrete wall surface, so that part is shaken when earthquake
Impact is absorbed by asphalt surface course, so that the anti seismic efficiency of wall is preferable；
Since asphalt surface course has preferable flexibility, so that asphalt surface course is not easily broken, so that concrete wall is shaken
Dynamic impact and when fragmentation, concrete block is protected and is limited by asphalt surface course, is not easy to pound and is fallen, and the influence to escape personnel is reduced；
Wall is avoided so that surface of wall is rigidly preferable by injecting concrete formation asphalt concrete pavement in pitch
Surface flexible influences by force very much appearance, while being connect by the concrete in injection pitch with concrete wall, and it is mixed to increase pitch
The connective stability of solidifying soil surface layer and concrete wall, after the concrete disintegrating injected in pitch, asphalt surface course will restore
Preferable elasticity is to protect concrete wall；
By, there are spacing, guaranteeing that concrete flows in spacing to protect between cast template and asphalt surface course in step S6
It can be preferably distributed in asphalt surface course when card concrete casting；
By the multiple casting in step S7 so that concrete by gravity flowing enter in pitch gap after obtain it is enough
Supplement, the effect for guaranteeing that concrete penetrates into pitch are preferable.
The present invention is further arranged to: in the S4, concrete wall dismantles cast template after reaching the presetting period at once
And the blind hole of several depth 1-2mm is pricked out on concrete wall.
By using above-mentioned technical proposal, by the way that several blind holes are arranged, so that the concrete and coagulation that are poured in step S7
The connection area of cob wall body increases so that the concrete in asphalt concrete pavement connect with concrete wall it is more steady
It is fixed, so that increasing the better effect of asphalt surface course and concrete wall connective stability.
The present invention is further arranged to: in the S5, asphalt surface course with a thickness of 10-15mm.
By using above-mentioned technical proposal, it is 10-15mm by thickness of bituminous surface, ensure that the intensity of asphalt surface course,
So that the effect of asphalt surface course protection concrete wall is preferable, while avoiding asphalt surface course is blocked up from causing wall blocked up.
The present invention is further arranged to: in the step S6, the spacing between cast template and asphalt surface course is 2-5mm.
It is 2-5mm by the spacing between cast template and asphalt surface course by using above-mentioned technical proposal, guarantees enough
Channel flowed for concrete, avoid spacing is too narrow from leading to concrete flowing slowly, while avoiding spacing is too wide from leading to wall mistake
It is thick.
The present invention is further arranged to: the asphalt includes the component of following mass fraction:
100 parts of pitch；
200-300 parts of coarse aggregate；
50-100 parts of fine aggregate；
30-40 parts of Carbon fibe；
5-8 parts of active carbon.
By using above-mentioned technical proposal, by using carbon fiber reinforcement asphalt, so that asphalt is strong
Degree preferably, it is not easy to crack, by active carbon reinforcement asphalt, adsorbed in asphalt using active carbon Carbon fibe with
Formed node so that carbon fiber preferably formed it is netted as a result, reinforcement pitch better effect.
The present invention is further arranged to: the asphalt further includes the component of following mass fraction:
In 10-12 parts of porphines of-four (4- carboxyl phenyl).
By using above-mentioned technical proposal, by-four (4- carboxyl phenyl) porphines in being added in asphalt, so that
The brittle point of asphalt declines, and is preferably suitable for cold district, so that the applicability of asphalt is wider.
The present invention is further arranged to: the asphalt further includes the component of following mass fraction:
15-20 parts of hollow glass microbead.
By using above-mentioned technical proposal, by the way that hollow glass microbead is added in asphalt, so that pitch coagulation
The heat insulation effect of native surface layer is preferable, so that wall has the effect of preferable insulation and sound insulation.
The present invention is further arranged to: the asphalt the preparation method is as follows:
A. pitch is heated to 160 DEG C -180 DEG C, carbon fiber, active carbon, fine aggregate is added, stirs evenly, form pitch
Pre-composition；
B. coarse aggregate is added in pitch pre-composition, stirs evenly to form asphalt.
By using above-mentioned technical proposal, by being eventually adding coarse aggregate, avoiding a large amount of coarse aggregates from being added good influences other
The case where raw material disperses in pitch guarantees the quality of asphalt so that each raw material is more readily dispersible uniformly.
In conclusion the invention has the following advantages:
1. asphalt surface course is coated on concrete wall surface, so that part jerk is absorbed by asphalt surface course when earthquake,
So that the anti seismic efficiency of wall is preferable；
2. forming asphalt concrete pavement by injection concrete in pitch, so that surface of wall is rigidly preferable, lead to simultaneously
The concrete crossed in injection pitch is connect with concrete wall, and the connection for increasing asphalt concrete pavement and concrete wall is steady
Qualitative, after the concrete disintegrating injected in pitch, asphalt surface course will restore preferable elasticity to protect concrete wall；
3. by-four (4- carboxyl phenyl) porphines in being added in asphalt, so that under the brittle point of asphalt
Drop is preferably suitable for cold district, so that the applicability of asphalt is wider.
