Abstract

The utility model discloses a stuff tyre foundation used for a cast-in-situ concrete cored slab. Middle through holes of the stuff tyre foundation are distributed along the horizontal direction at intervals in the same direction, all of the through holes are closed down at two ends, and the existence of supports among the through holes can greatly improve the intensity of the stuff tyre foundation; the bottom of the stuff tyre foundation is provided with a horniness material layer the middle of which is provided with steel bars or a steel bar net, both ends of the steel bars or the outer end of the steel bar net extend out of the stuff tyre foundation and can be connected with steel bars in the cored slab, the bottom of the cored slab does not need a protective layer, and the integrality of the cored slab is good; the middle of the stuff tyre foundation is provided with through holes both ends of which are open along the vertical direction at intervals. Concrete can flow to the lower side of the stuff tyre foundation along the through holes during the construction process of hollow floorslab, so as to cause the stuff tyre foundation and the concrete to be solidified into an integer, thereby facilitating improving the intensity of the floorslab. The stuff tyre foundation has simple structure, easy manufacture and high intensity.

Description

Cast-in-situ concrete hollow slab is with filling carcass

Technical field

The utility model belongs to building material technical field, and particularly a kind of cast-in-situ concrete hollow slab is with filling carcass.

Background technology

In the making or work progress of reinforced concrete hollow slab, the filling block of often filling some light materials in concrete is to reduce dead load and the concrete insulation of raising, heat insulation, soundproof effect, and available coagulation soil filling block has metal tube, hollow cement thin-walled pipe, hollow cement thin-walled box, expanded material filling block etc.Metal tube cost height, and serious waste of resources; Hollow cement thin-walled pipe and thin-walled box cost are low, but because hollow intensity is relatively poor, need particular manufacturing craft in the process, and processing is complicated; The expanded material filling block is in light weight, cost is low, shape is controlled easily, but itself matter is soft, stressed deforming easily when excessive in transportation or construction and cracked.

The utility model content

The utility model purpose be to provide a kind of simple in structure, be easy to process, cast-in-situ concrete hollow slab that intensity is high is with filling carcass.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of cast-in-situ concrete hollow slab is filled the middle spaced apart in the same way through hole of along continuous straight runs, the through hole closed at both ends of being provided with of carcass with filling carcass; The filling carcass is stretched out in the hard material layer, reinforcing bar two ends or the steel mesh reinforcement outer end that are provided with reinforcing bar or steel mesh reinforcement in bottom the filling carcass being, and its top is divided into the light material layer.

Fill the middle plug hole that vertically is interval with both ends open of carcass, plug hole is not communicated with described through hole.

Fill the carcass end face or/and be provided with the armature bed of material in the middle of the bottom surface layer.

Fill carcass intermediate throughholes along continuous straight runs layered arrangement in the same way, the different layers through hole is corresponding or be staggeredly arranged.

In the utility model, fill the available cement mortar that is mixed with light granular material such as foam grain, perlite particle of carcass light material layer and make, hard material layer can be cement concrete layer, and it is light to fill the carcass overall weight, and processing cost is low; Production can be carried out on smooth cement floor, and mould can be produced specially; Fill in the hard material layer of carcass bottom reinforcing bar or steel mesh reinforcement and stretch out the filling carcass, can directly fix in the use, need not topping, good integrity bottom the hollowcore slab with hollowcore slab steel mesh reinforcement overlap joint.

When filling carcass intermediate throughholes along continuous straight runs when arranging at interval in the same way, effect and metal tube, light-wall pipe, thin-walled box are suitable, but owing to the existence of supporting between the hole, intensity improves greatly; But fill carcass intermediate throughholes along continuous straight runs individual layer layout or multilayer layout in the same way, can satisfy under the different situations filling the different requirements of carcass thickness; The different layers through hole is staggeredly arranged, and intensity is higher; Fill the middle through hole that vertically is interval with both ends open of carcass, can in carrying out the cassette ceiling work progress, make concrete below through hole flow to the filling carcass, filling carcass and concrete are solidified as a whole, helping improving floor strength.Fill the armature bed of material that carcass pushes up, bottom surface layer is middle and can be glass fiber mesh, grid cloth, reinforced mesh, gauze wire cloth etc., can effectively improve the globality and the intensity of filling carcass.

The specific embodiment

As Fig. 1; Fig. 2; shown in Figure 7; embodiment 1 of the present utility model; filling the carcass body is hexahedron; the light material layer 1 of filling carcass body top is cement mortar and light granules mixture; the hard material layer 6 that fills the block body bottom is cement concrete layer; be provided with the spaced apart in the same way through hole 2 of along continuous straight runs in the middle of filling the carcass body; through hole 2 corresponding layouts of different layers; the closed at both ends of through hole 2; fill the plug hole 3 that vertically is interval with both ends open in the carcass body; plug hole 3 is not communicated with through hole 2, is provided with steel mesh reinforcement 4 in the hard material layer 6, and the filling carcass is stretched out in the outer end of steel steel mesh reinforcement 4.

As shown in Figure 3, embodiment 2 of the present utility model is with the difference of embodiment 1: what be provided with in the described hard material layer 6 is reinforcing bar 5, and the filling carcass is stretched out at the two ends of reinforcing bar 5, and fills the plug hole that vertical direction is not set in the carcass body.

Reinforcing bar 5 in the foregoing description 3 is not limited only to the mode of unidirectional setting shown in Figure 3, can certainly adopt crisscross set-up mode.

As shown in Figure 4, embodiment 3 of the present utility model is with the difference of embodiment 1: is provided with the armature bed of material 7 in the middle of the end face of described filling carcass body and the bottom surface layer, the material of the armature bed of material 7 is a glass fiber mesh.

The armature bed of material 7 in the foregoing description 4 can certainly only be arranged in one of them of top layer and bottom except being arranged at top layer and bottom simultaneously.

As shown in Figure 5, embodiment 4 of the present utility model, be with the difference of embodiment 1: the through hole 2 of described different layers is for being staggeredly arranged.

The through hole 2 of the different layers in the

foregoing description

2,3 can certainly be interspersed.

As shown in Figure 6, embodiment 5 of the present utility model, be with the difference of embodiment 1: the spaced apart in the same way through hole 2 of described along continuous straight runs only is provided with one deck, and fills the plug hole that vertical direction is not set in the carcass body.
