Abstract
The present invention relates to a light stuffing die member for filling cast-in-place reinforced concrete, which comprises a stuffing body (1). The present invention is characterized in that the stuffing body (1) is a corrugated stuffing body; at least one convex module (3) is arranged on at least one side surface (2) of the corrugated stuffing body (1). In this way, after the light stuffing die member is used in a reinforced concrete floor, a cast-in-place concrete rib formed between two light stuffing die members in the floor becomes into a truss rod type cast-in-place concrete rib or a cast-in-place concrete rib of which both sides are provided with truss-shaped rods; thus, the weight of the cast-in-place concrete rib is greatly reduced, materials are saved, the weight of the whole floor is reduced, and the shock resistance of the floor is increased. Simultaneously, the light stuffing die member also has the characteristics of light weight, high strength, simple structure, convenient construction and transportation, etc. The present invention is suitable for various hollow floors, roofs, foundation bottom slabs, walls and hollow bridges, which are made of cast-in-place reinforced concrete, particularly for cast-in-place reinforced concrete hollow beamless floors.
Description
(1) technical field
The present invention relates to a kind of light core structural member for filling cast-in-situs reinforcing bar concrete.
(2) background technology
Advantages such as at present, the building of brick mix structure and frame construction major part adopts precast hollow slab as floor structure, and it is fast that this floor structure has speed of application, and cost is low.But, only use the cement mortar joint filling, thereby globality is poor, is unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur owing to firmly do not link between adjacent two precast hollow slabs.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (solid, hollow), though solved antidetonation and problems of crack, will use template in a large number during construction, have not only increased expense, and have slowed down speed of application, have prolonged the duration.As the patent No. is ZL01206422.X, name is called " open-spandrel sandwich board built-in template " utility model patent, it discloses a kind of open-spandrel sandwich board built-in template, this built-in template is solid, and be that expansion type gathers the solid built-in template of stupid vinyl plastics, or be the solid built-in template of magnesium oxychloride material, or be the solid built-in template of perlite material, its cross sectional shape can be the cross sectional shape of square, rectangle, circle, ellipse, arc or circular arc and rectilinear(-al), have technology simple, with low cost, do not need advantages such as the demoulding, construction period be short.And for example the patent No. is ZL00207318.8, name is called " cast-in-place concrete hidden rib floor structure " utility model patent, it is made up of upper plate, lower plate, dark rib and formwork, dark rib and formwork are alternately between upper plate and lower plate, and by dark rib upper plate and lower plate are connected as one, have sound insulation, heat insulation, save material, stressed rationally, advantage such as globality, shock resistance be good.The formwork that uses in it can be solid, and shapes such as that its profile can be designed to as required is square, rectangle, circle, polygon can play sound insulation, heat insulation, the effect of saving material and weight.But this class shuttering member as carcass applications behind cast-in-situ reinforced concrete hollow structure superstructure, the superstructure weight that forms is still heavier relatively, be unfavorable for antidetonation and save material, simultaneously, production is inconvenient, cost is high, therefore, develop a kind of novel light core structural member for filling cast-in-situs reinforcing bar concrete for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of light core structural member for filling cast-in-situs reinforcing bar concrete, it is lighter relatively to be applied to the floor structure weight that forms behind the cast-in-situ reinforced concrete floor slab in space structure, shock resistance is good, save material, and member have in light weight, intensity is high, simple in structure, convenient construction and transport, convenient for production, characteristics such as cost is low.
Solution of the present invention is on the basis of existing technology, comprises carcass, it is characterized in that carcass is the ripple carcass, and the module of at least one protrusion is arranged at least one side of ripple carcass, and module is the ripple module.Like this, after this light tyre moulding member is applied to the reinforced concrete structure superstructure, promptly become truss member type Cast-in-place concrete rib by the Cast-in-place concrete rib that forms between the light tyre moulding member in the superstructure, or the Cast-in-place concrete rib of truss-like rod member is worn in both sides, thereby the weight of Cast-in-place concrete rib alleviates greatly, save material, also make the weight saving of whole floor structure, anti-seismic performance improves; Simultaneously, because module is the ripple module, thereby the more convenient production of light tyre moulding member, help reducing the cost of production of light tyre moulding member; In addition, characteristics such as that light tyre moulding member also has is in light weight, intensity is high, simple in structure, convenient construction and transport, thereby reached purpose of the present invention, be adapted to use in steel bar reinforced hollow concrete roof cast-in-situs, roof system, sole plate, body of wall, the hollow bridges, be particularly useful for the cast-in-situ reinforced concrete hollow arch without beam and use.
Feature of the present invention is that also the ripple on described ripple carcass and the ripple module is positive ripple or oblique ripple or arc ripple or their combination.Like this, the bellows-shaped style on the light tyre moulding member is many, and convenient design is selected for use with production unit, helps reducing and produces and construction cost.
Feature of the present invention is that also the ripple on described ripple carcass and the ripple module is equidistant ripple or non-equidistance ripple.Like this, the ripple spacing on the light tyre moulding member can be selected for use as required, helps reducing producing and construction cost.
