Description
Technical field
The present invention relates to a kind of architectural construction technologies, and in particular to one kind is based on improving concreting in construction
The technique of quality.
Background technique
Building is based on timber buildings, and the traditional architecture in west is based on masonry structure.Modern building is then with steel
Based on reinforced concrete.
Chinese ancient architecture has simple simple and elegant style, is knot with yoke structure mainly using cogongrass, timber as construction material
Structure mode (components such as column, beam, a tree, used in making timber for boats, purlin, rafter) is combined according to actual size, shape and the spacing that structure needs.It is this
Building structure mode reflects the clear, orderly of ancient times patriarchal society structure and stablizes.Due to wooden material production beam column not
Huge inner space is easily formed, ancient architecture just dexterously using outport place, forms garden.Garden is the base of building
Our unit, it is both closed and open；Be both it is artificial and naturally, can bow and plant flowers, plants and trees, face upward and serve as a lookout
Cloud life becomes the another performance of ancients " harmony between man and nature " idea, also embodies Chinese's not only implicit introversion, but also pioneer and keep forging ahead
National character.The groups of building that ancient times somewhat larger building is all made of several gardens, single building and garden are along one
Move towards to arrange calmly, it is A distinction should be made between what is primary and what is secondary, there is climax to have transition, become the space for the depth that has levels, has, shows a kind of Chinese and chased after
The integrated beauty and deep beauty asked.Wherein palace, the building that temple one kind is more solemn, often one by one along central axes
It is longitudinally arranged key construction, monosymmetric arrangement secondary structure, arrangement balancing is unfolded, fascinating.
Ancients can achieve the effect that beauty with the design techniques such as balance, harmonious, symmetrical, light and shade axis very early.Ancient times
Weight artistic decoration is built, but uncomplicated, only makees emphasis decoration, such as window hood, lintel, ridge in main portions, layout is mostly to weigh
Square to development, skyscraper is not weighed, until there is building pagoda, high building is just able to prevailing after Buddhism is incoming.The one of building
Cutting art processing is also all processing to structural system and component, if color, decoration are in conjunction with component, constitute enrich it is gorgeous
Art achievements, carved beams and painted rafter, body are graceful and colorful；Couplet written on scrolls and hung on the pillars of a hall horizontal inscribed board, excites interest and charm and reverie is infinite, ancient architecture category
It is flouring, including palace, cemetery park, monastery, palace sight, gardens, bridge, tower brake etc..
Due to being not well mastered skill when the concreting of existing building, easy to crack and appearance after concreting is caused
Hollowing influences later period use.
Summary of the invention
The technical problem to be solved by the present invention is to, due to being not well mastered skill, make when the concreting of existing building
At easy to crack and hollowing occur after concreting, influencing the later period is used, and it is an object of the present invention to provide a kind of based in construction
The technique for improving concrete pouring quality causes to mix due to being not well mastered skill when solving the concreting of existing building
The problem of solidifying soil pours rear easy to crack and hollowing occurs, influences later period use.
The present invention is achieved through the following technical solutions:
Based on the technique for improving concrete pouring quality in construction, comprising the following steps:
(1) self-falling mixer is used, charging sequence is preferably, first plus l/2 water consumption, then plus stone, cement, sand stirring
Lmin, then plus remaining 1/2 water consumption continue to stir, mixing time is no less than 1.5min, and mixing time should be appropriate when mixing additive
Extend, a variety of materials accurate measurement, measuring accuracy: cement, water, additive are ± 2%, and aggregate is ± 3%, and the Pluvial should often survey
Sand, stone moisture content are determined, to guarantee that the ratio of mud is accurate；
(2) concrete is transported to pouring location from stirring place, and perdurabgility shortens as far as possible, is preferably controlled according to temperature 0.5
Within~lh, when using commerical ready-mixed concrete, unloads again after should being sufficiently stirred, do not allow arbitrarily to add water, concrete isolates
When, secondary agitation is answered before pouring, the concrete having been the beginning of coagulation should not use；
(3) the mobile spacing of poker vibrator is not preferably greater than 1.5 times of acting radial of vibrator, generally should be smaller than 50cm,
Door opening two sides constructional column wants vibration compacting, must not leakage, it is each vibration point perdurabgility, with surface present laitance and no longer sink
Fall to reach requirement, avoid collision reinforcing bar, template, built-in fitting, built-in pipe, Side fascia cavity water proof structure etc., discovery have deformation,
Displacement, each related trades mutual cooperation are handled；
(4) should be after concrete cooling extremely+5 DEG C, surface temperature of concrete and ambient temperature differences are greater than 15 DEG C after demoulding
When, covering curing is answered on surface, makes its Slow cooling；
(5) concrete strength is greater than 1MPa when room temperature, and when teletostage mixes antifreezing agent, tears open when concrete strength being made to reach 4MPa
Mould, when guaranteeing demoulding, metope, corner are modified in wall not sticking to mould, not arrisdefect, not crack in time, and the timely wet curing of room temperature is supported
The shield time is no less than 7d, and irrigation times should be able to keep concrete wet.
Compared with prior art, the present invention having the following advantages and benefits: the present invention can be improved concrete and pour
Quality after building, so that service life is guaranteed.
