Description
Technical field
The present invention relates to a kind of reinforced concrete sandwich beam
Manufacture method and
Combination type sandwich parts, belongs to building structure reinforcing bar concrete sandwich beam manufacture technology field.
Background technology
Armored concrete sandwich beam is as a kind of combinative structure, its sandwich material often has lightweight, cheap feature, by inserting sandwich parts inside reinforced beam, the cross section making reinforced beam is increased (being similar to solid beam is become box beam), reaches to alleviate deadweight, reduce the purpose such as cost, increase beam bearing capacity.But at present in Practical Project, making sandwich parts
During reinforced concrete sandwich beam, it is common that according to the requirement of the reinforced concrete sandwich beam of required making, use plank or steel plate to produce the sandwich parts of corresponding size at the scene, then this sandwich parts is put into the reinforced concrete sandwich beam pouring out sandwich parts in casting mold.This production method of prior art not only also exists that inefficiency, site operation be complicated, trouble, poor for applicability, construction quality is poor, the problem that wastes time and energy, but also there is the foam concrete that can not effectively utilize slag, flyash equal industrial residue material the to make problem as construction material.Owing to there is these problems so that armored concrete sandwich beam is slower development in the promoting the use of Practical Project.Therefore, the production method of the reinforced concrete sandwich beam of existing sandwich parts formula or not ideal enough.
Summary of the invention
The present invention seeks to: provide that a kind of efficiency of construction is high, construction quality is good and can effectively utilize the reinforced concrete sandwich beam of foam concrete or formed plastic light material
Manufacture method and
Combination type sandwich parts, to overcome the deficiencies in the prior art.
The present invention is achieved in that the manufacture method of a kind of reinforced concrete sandwich beam of the present invention is, light material is used to produce the combination type sandwich parts assembly parts of unified specification at workshop in advance, then after these combination type sandwich parts assembly parts being transported to job site, the size of the sandwich parts according to reinforced concrete sandwich beam to be poured, carry out assembling by combination type sandwich parts assembly parts and obtain the combination type sandwich parts of required size, after this combination type sandwich parts is put into as the sandwich parts of reinforced concrete sandwich beam the steel reinforcement cage in the casting moulds of pouring reinforcement concrete sandwich beam, again this casting moulds is carried out concrete cast, so can be prepared by the reinforced concrete sandwich beam of combination type sandwich parts formula.
Above-mentioned light material is foam concrete or foam plastics.
A kind of combination type sandwich parts of the present invention according to said method structure is, this combination type sandwich parts is assembled by combination type sandwich parts assembly parts and constitutes, a combination thereof formula sandwich parts assembly parts be cross sectional shape be foursquare square straight-bar, the end face of combination type sandwich parts assembly parts being shaped as square straight-bar is provided with end tenon, its other end is provided with the end mortise that can insert end tenon；Being respectively arranged at two ends with tenon on two adjacent planes of the combination type square straight-bar of sandwich parts assembly parts, being respectively arranged at two ends with on the another two adjacent plane of the combination type square straight-bar of sandwich parts assembly parts can insert the mortise of tenon.
The above-mentioned cross sectional shape being assembled the combination type sandwich parts constituted by combination type sandwich parts assembly parts is square or rectangular.
The above-mentioned end tenon being arranged in combination type sandwich parts assembly parts both ends of the surface and the center of circle centrage of end mortise coincide with the centrage of combination type sandwich parts assembly parts square pole.
On above-mentioned two adjacent planes being arranged on the combination type square straight-bar of sandwich parts assembly parts, the center of circle centrage with the tenon of one end and mortise all intersects in the plane of the same centrage being perpendicular to combination type sandwich parts assembly parts square pole and with this centrage.
Owing to have employed technique scheme, the present invention is by using light material to produce the combination type sandwich parts assembly parts of unified specification at workshop in advance, then after combination type sandwich parts assembly parts being transported to job site, the size of the sandwich parts according to reinforced concrete sandwich beam to be poured, carry out assembling by combination type sandwich parts assembly parts and obtain the combination type sandwich parts mode of required size, carry out the cast of reinforced concrete sandwich beam the most in a conventional manner, owing to the combination type sandwich parts assembly parts of the present invention produce at workshop, therefore production line can be used to produce on a large scale, this can not only be effectively ensured the quality of product, but also substantially increase production efficiency and reduce production cost；Additionally, the present invention also has the following characteristics that
1
, the present invention have employed the combination type sandwich parts of modular lightweight of " mortise-tenon joint " first, this establishes " modularization " and the Construction Mode of " assembled " to the making of armored concrete sandwich beam；
2
, the present invention be easy to construction, the suitability is strong, and single combination type sandwich parts assembly parts are made by unified modulus, have the feature such as light weight, dimensional standard.In work progress, can be had again the preferable suitability by commonly manually carrying out carrying and carrying out Optional assembling according to the different beam section demands of engineering while being easy to construction.
3
, the present invention there is preferable economy, by prior art 200
～300kg/m3
The totle drilling cost of foam concrete only has 100
Calculate about unit, as sandwich material, than existing sandwich parts material, there are obvious economic advantages.
4
, the present invention there is feature easy to process, the combination type sandwich parts assembly parts of the present invention not only can carry out producing prefabricated in plant floor, it is also possible to the most directly pours and makes.
5
, use the present invention can improve the mechanical property of structure significantly, the present invention uses light sandwich component, not only can alleviate the deadweight of reinforced beam, reduce cost, moreover it is possible to increase the cross section of beam, thus improve the bending resistance etc. of reinforced beam.
6
, use the present invention to have profit is useless, environmental protection, shockproof, the effect of noise reduction.The present invention uses foam concrete can utilize slag, flyash equal industrial residue in a large number as sandwich parts, the advantage with the useless environmental protection of profit；Simultaneously because foam concrete has porous feature, therefore the combination type sandwich parts of the present invention has again preferable shockproof Noise Reduction, and this combination type sandwich parts is a kind of functional structure with plurality of advantages.
In sum, compared with prior art, the present invention not only has an advantage that efficiency of construction is high, construction quality is good to the present invention, but also have that cost of manufacture is low, energy-saving and environmental protection the advantage such as mechanical property of girder construction can be improved.
