Abstract
The present invention relates to a shuttering member for cast-in-place concrete, which comprises a light material member (1). The present invention is characterized in that an enwrapping layer is hermetically and totally enwrapped at the exterior of the light material member (1). Therefore, because the manufacture of the light material member (1) is easy, a large amount of dies are not required. Simultaneously, the exterior of the light material member (1) is provided with peripheral lateral walls (2) and a lower bottom (3) to be used as protection layers, and therefore, the present invention has high intensity and is not easy to damage. Besides, the shuttering member also has the characteristics of light weight, convenient transportation, heat preservation, heat insulation, sound isolation, etc. The present invention is suitable for various occasions, such as floors, roofs, foundation slabs, walls, empty bridges, bulky concrete projects, etc., which are made of cast-in-place concrete.
Description
The application for the applying date be that March 11, application number in 2003 are 03119749.3, name is called the dividing an application of application for a patent for invention of " a kind of shuttering member for in-site pouring concrete ".
(1) technical field
The present invention relates to a kind of shuttering member for in-site pouring concrete.
(2) background technology
The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, it is fast that this floor structure has speed of application, advantages such as cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, is unfavorable for antidetonation, and slit cracking, infiltration often appear, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (hollow, solid).The patent No. is ZL00207318.8's " 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 upper plate and lower plate are connected as one by dark rib, have sound insulation, heat insulation, the advantage of saving material, simultaneously, floor structure is stressed reasonable on all directions, has good globality.Because its formwork material can be made by light-weight high-strength materials such as plant straw, glass fiber reinforced plastic, sheet iron plate, glass fibre cements, shapes such as that its profile can be designed to as requested is square, rectangle, circle, polygon, can be hollow or solid, therefore, this kind formwork has applicability preferably.But hollow for it, then often make comparatively difficulty, need be than multi-mould, cost is higher relatively; And solid light material member, then because light material is a plant straw etc., its insufficient strength does not have topping, and is damaged easily in carrying, work progress, thereby cost is higher relatively.Therefore, develop a kind of novel shuttering member for in-site pouring concrete for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of shuttering member for in-site pouring concrete, have characteristics such as make easily, intensity is high, cracky, cost be not low.
Solution of the present invention is on the basis of existing technology, comprise the light material member, it is characterized in that also comprising on every side sidewall, go to the bottom, on every side sidewall and go to the bottom the light material member is wrapped on every side sidewall and the uncovered cavity that surrounds of going to the bottom in, there is a vertical hole that runs through the light material member at the middle part of going to the bottom.The used light material of its light material member can be foam concrete, aerating concrete, expanded perlite, expanded vermiculite, foamed plastics or lightweight wood chip piece etc.Like this, owing to wrap up on every side sidewall and go to the bottom, thereby make easily outward on the light material member, do not need a large amount of moulds; Simultaneously, the light material member has on every side sidewall outward and goes to the bottom as topping, thereby the intensity height, cracky not, and comparatively speaking, its integrated cost is also lower, thereby has overcome the deficiencies in the prior art, has reached purpose of the present invention.In addition, characteristics such as that this kind shuttering member also has is in light weight, convenient in carrying, insulation, heat insulation, sound insulation, when being applied to superstructure, shuttering member can be wrapped in the steel bar concrete fully, also can it go to the bottom and replace the lower plate of superstructure, form close ribbed building roof, be applicable to different occasions such as various cast-in-situ reinforced concrete superstructures, roof system, sole plate, body of wall, hollow bridges, prevention of mass concrete engineering.
Feature of the present invention is that also the used light material of light material member is a foamed plastics.
Feature of the present invention is that also the used light material of light material member is the foam concrete.
Feature of the present invention is that also the used light material of light material member is the aerating concrete.
Feature of the present invention is that also the used light material of light material member is an expanded perlite.
Feature of the present invention also be around at least one sidewall and go to the bottom between a re-entrant angle is arranged.Like this, be applied to the concrete superstructure after, the Cast-in-place concrete rib that forms between the shuttering member is I shape or inverted T-shaped rib, has improved the mechanical property of superstructure.
Feature of the present invention also be at least two relative around sidewalls and go to the bottom between re-entrant angle is arranged.Like this, be applied to the concrete superstructure after, the Cast-in-place concrete rib that forms between the shuttering member is I shape or inverted T-shaped rib, has further improved the mechanical property of superstructure.
Feature of the present invention is that also sidewall is provided with reinforcing rib on every side.Like this, the intensity and the rigidity of shuttering member are bigger, and stress performance is better.
