Abstract

The present invention relates to construction technology for building concrete structure and used templates thereof. The present invention mainly solves the problems that lots of plate material, such as timber, etc., serves as the templates and needs to be consumed in the traditional construction for building concrete posts, beams and plates, concrete is cast in the templates which are dismantled after a curing period, and therefore, work, time, material, etc. are wasted. Concrete building moulds used by the present invention are novel moulds which are manufactured and assembled according to specific shapes of various kinds of concrete structure, the concrete is cast in the moulds which do not need to be dismantled after achieving the curing period, and the moulds which are tightly connected into integration with the concrete structure become a part of the concrete structure (replace a floated coat outside the original concrete structure). The construction technology for building the concrete structure is greatly simplified, lots of plate material is saved, construction periods are shortened, and building veneer projects can be directly carried out on the outside of the glabrous moulds at the later stage of the projects. The present invention belongs to the significant innovation of building trades.

Description

Used template in the construction process for building concrete structure
Technical field
The present invention relates to template used in the architectural construction technology.
Background technology
At present, the building construction process of concrete frame structural building or building is actually a process that repeatedly repeats a cover program.This process is: make template, make reinforcing bar, set up scaffold, assembled formwork is installed reinforcing bar, pour concrete, dismounting template.Repeat above process then.Go round and begin again and repeat same process one after another, complete until the main structure body engineering.Such construction pattern should be the construction pattern of just having used since concrete comes out.Though reform was several times arranged in history, became veneer, Engraved bamboo clappers, steel template etc. by solid wood board.Reform that can be such has also just changed mould material, and whole construction pattern and program are not had a bit change.The general this construction pattern of China exists the problem of following several aspects at present
(1), the construction stage is all bigger to the consumption of timber, steel and all kinds of sheet materials.And the number of turnover of these materials generally has only three times, the every use of material once, volume of the circular flow needs to replenish 30% new material at least.Particularly consume a large amount of timber, can cause the forest reserves further to be cut down, and then cause soil erosion, ecological disequilibrium takes a bath the country and people.
(2), the template construct engineering quantity of installing is big, and consumption is many man-hour.Not only consume man-hour during form removable, and damage template.Impaired template does not often have recycle value and becomes waste product.
(3), crude because of the concrete body structure surface, so out-of-flatness is consumption worker feed consumption, the particularly flat-top part of plastering during later stage decorations.
Summary of the invention
The objective of the invention is to provide a kind of construction formwork of uniqueness, its template and concrete structure are united two into one, exempted the pour concrete operation of palpus stripping later on, accomplished that labor and material saving saves time, improved concrete structure construction quality for the building concrete structure construction.
Purpose of the present invention is realized by following scheme:
Construction process for building concrete structure includes following operation: make template, make reinforcing bar, set up scaffold, assembled formwork, installation reinforcing bar, pour concrete.Said template is by the prefabricated cement spare template that the given shape of various concrete structures is made and assembly unit goes out, when pour concrete in it and after reaching curing time, need not stripping, and its template and concrete structure closely are connected as a single entity.
Used template in a kind of construction process for building concrete structure, it is characterized in that: it is prefabricated cement spare, the selection of material is: cement 40~60%, thin river sand 30~50%, flyash 8%, gesso 2%, adding entry in 1: 0.12~0.26 ratio in above mortar fully stirs, when reaching more than 3 minutes, ratio in 1: 0.017~0.020 in mortar adds glass fiber or other fibrous material, stir and it was evenly distributed in the slip in 5 minutes, then with slip casting to making in the template forming mould, mould is placed on to rock rocks 5~6 minutes on the machine, can quietly stop maintenance 12~16 hours then, open dovetail groove and plucking processing at template surface again, treat maintenance expiration back reprocessing post, beam, the assembly unit tongue and groove and the beam of plate, the connectivity port of intercolumniation.
Template used in the above-mentioned construction process for building concrete structure is assembled by the polylith veneer, the weight≤30kg of every veneer.
The invention has the advantages that used construction formwork is simple in structure, produce easily, it is used for the concrete structure construction makes its work simplification, need not remove this template after the completion, and template and concrete structure are connected as a single entity closely.Because prefabricated cement formwork is mechanical-moulded, its finish is very high, and the finishing stage in engineering later stage need not be carried out the plastering process of cylinder, beam face, flat-top.This has not only saved above several labor and materials losses, has also saved the labor and materials of setting up full hall scaffold simultaneously.The present invention has changed traditional construction process for building concrete structure, has simplified operation, has saved a large amount of timber, has reduced construction cost and building costs, for protection environment and ecological resources very big benefit is arranged all.

The specific embodiment
The disclosed structure of above accompanying drawing is the structure of one embodiment of the present of invention.Among the figure, 1~4 for being combined into each veneer of template; 5 is the structure concrete; 6 is dovetail groove.
Technical essential of the present invention:
Technical essential of the present invention is: change existing construction work concrete structure construction mode, lack and use or do not use wooden template.Use prefabricated cement formwork instead and substitute construction formworks such as timber, bamboo board and steel form.
1, prefabricated cement concrete structure construction template is that inserts, glass fiber (or other mineral wool material) are that tensile materials, gesso are the cement mortar of accelerating combinations such as initial setting time material with cement as cementitious matter, thin river sand exactly, in particular manufacturing craft, pour into cement plate with this mortar, the plucking fluting is carried out on the surface that template is combined with the structure concrete then, enterprise is cut and opens at the position that template combines with template, thereby manufacture cement concrete structure construction template.
Not only production technology is simple for this template of the present invention, and is cheap for manufacturing cost, and product plasticity is strong, and bigger superiority is: the material that the production template uses material and building concrete structure to use belongs to the same material kind.Their various physical performance indexs and physical change all are identical.Compatibility between template and the structure is very good, and the stability of solid-state bond is also very good.
This template of the present invention is much simpler than traditional form of construction work on construction technology, because after in a single day prefabricated cement concrete structure construction template be assembled into the needed shape of concrete structure, just combine with the structure concrete, has become the topping of body structure surface.So template successfully just need not stripping once assembling.So not only saved material, saved artificial simultaneously again.
2, prefabricated cement concrete structure construction template does not change the section area of structure.Do not influence the load design of structure.We can be understood as it is body structure surface one deck motar, makes template the prescription of this one deck motar is improved, and adds the prefabricated one-tenth construction formwork of some fibre again.Made particular processing at template inner surface (surface that combines with the structure concrete) again, watered after the concrete in the die cavity, use the combination of dovetail groove mode between template and the structure concrete, add template when making, reserve a lot of short glass fiber stakes in swallow layer groove, all-pervasive cement paste is with regard to be bonded together with template firmly (referring to Fig. 1) when the structure concrete waters.
After structure construction is finished, need not stripping, only remove to support and get final product.Save the worker and the material of body structure surface float work in the future simultaneously, and shortened the construction period.Because template is in plant produced, its surface is very bright and clean, and the engineering later stage can directly construction building be surface-veneer engineered in the above.
3, prefabricated cement concrete structure construction template is produced with the mechanization mode in factory.Measure the quality certification system that strictness all will be arranged from selecting materials to.Only in this way could protect product standard quality unified and product good.Production technology design therefore of the present invention is based on mechanization production.

2, the definite foundation about template veneer length (or claiming area) is such:
At first will obey a prerequisite: that is exactly a handled easily.The weight of every veneer should be controlled in the 30KG, if too heavyly just be inconvenient to splice installation.Can produce monoblock during plant produced, but must be cut into small pieces during product export, the scene can assembly unit.
3, the specific design scheme of template
A, at present in the Cross section Design of the building field concrete structural column of China, all select 240 * 240,300 * 300,300 * 400,400 * 400,400 * 500,400 * 600 uniform section sizes basically for use.Although it also is southern and northern in the difference of selecting for use on the grade having any different.Should this be the main flow of the present architectural design concept of China.And the main flow trend of house floor height also is to select absolute altitudes such as 2.80,3.00,3.20,3.30 basically for use.This just provides a basic standard for our deisgn product specification.So the total principle of the specifications design of product is: with construction module design production technology and product template.Needs with the user are determined product specification.Concrete structural column, beam, template die plate termination form are seen Fig. 3, Fig. 6, Fig. 8 respectively.
