Abstract
The invention discloses a cast-in-situ concrete hollow floor comprising a bottom surface reinforcement, a tube filler internal mould, a mould plate and a steel tube bracket; the cast-in-situ concrete hollow floor further comprises a limiting element, a press rod and a bracket fixing embedded part, wherein the limiting element is vertically sleeved on the tube filler internal mould; the limiting element comprises a plurality of intercostal corners, the press rod is arranged on the intercostal corners of the limiting element and fixed with the limiting element; the bracket fixing embedded part comprises a cross rod and two vertical rods, wherein the cross rod is arranged above the press rod, and the vertical rods are connected with the steel tube bracket and then tightly screwed and sleeved on the press rod after passing through an electric drill hole on the mould plate. The invention further discloses a tube filler internal mould fixing method, the steel tube is bent into a plurality of continuous omega shapes according to the overall dimension and the amount of the steel tube internal mould, so as to form the limiting element, and the limiting element is vertically sleeved on the steel tube internal mould, and fixed by a connection rod and the bracket fixing embedded part. The cast-in-situ concrete hollow floor and the method have the advantages that the cast-in-situ concrete hollow floor is simple to manufacture and convenient to install, and the construction quality of the cast-in-situ concrete hollow floor is guaranteed.
Description
Technical field
The invention belongs to the realm of building construction, particularly a kind of cast-in-situ reinforced concrete hollow floor and cylinder in-core mould fixing means.
Background technology
Cast-in-situ reinforced concrete hollow floor is to be subject to force direction that the cylinder in-core mould of space is set on the edge, middle part, cross section of cast-in-situ floor, the beam of structure generally secretly sets in plate, after concreting, floor becomes hollow-core construction, weight reduction compared with common beam and slab structure, span increases, and noise insulation effect improves, reduce mould material and manpower consumption, facilitate for decorating, improved space availability ratio, therefore promoted rapidly in builing industry.
When cast-in-situ hollow floor plate construction, emphasis to solve a problem: behind the location of cylinder in-core mould in floor, prevent single internal mold floating and displacement, and prevent the local floating of floor bottom mould and reinforcing bar displacement, ensure the construction quality of cast-in-place concrete hollow building roof.
Summary of the invention
The object of the invention is the problem in order to solve above-mentioned cylinder in-core mould floating and displacement, a kind of cast-in-situ reinforced concrete hollow floor is provided.
For realizing goal of the invention, the technical scheme adopting is such: cast-in-situ reinforced concrete hollow floor, comprise bottom surface reinforcing bar, cylinder in-core mould, template, steel pipe support, and it is characterized in that: it also comprises that locating part, depression bar and support fix built-in fitting; Locating part vertical sleeve is on cylinder in-core mould, and locating part has some intercostal bent angles, and depression bar is placed on the intercostal corner of locating part, fixes with locating part; The fixing built-in fitting of support has a cross bar and two montants, and cross bar is above depression bar, and montant is connected to tighten with steel pipe support through the electric drill hole in template and is nested with above depression bar.
Further improve and be, described locating part is that steel pipe is bent into multiple continuous " Ω " shapes and forms.
Cylinder in-core mould fixed connecting piece forms the member of limiting displacement in cylinder in-core mould upside and the left and right sides, form entirety by fixed connecting piece and end muscle, gluten, support for shuttering, can effectively prevent muscle produces under concrete buoyancy and the perturbation action that vibrates at the bottom of single internal mold and floor floating and displacement.This fixed connecting piece is made simple, easy for installation; And by the size of fixed connecting piece is regulated, the cylinder in-core mould of all size is all suitable for; By the setting of fixed connecting piece, can avoid adopting common iron wire to reinforce the quality problems such as iron wire fracture, insufficient rigidity that occur in measure of anti float.

Detailed description of the invention
Referring to accompanying drawing.Cast-in-situ reinforced concrete hollow floor, comprises that locating part 1, depression bar 2 and support fix built-in fitting 3, cylinder in-core mould 4, bottom surface reinforcing bar 5, template 6, steel pipe support 7; Locating part 1 has some intercostal bent angles 11, and depression bar 2 is arranged on the intercostal corner 11 of locating part 1, fixing with locating part 1; The fixing built-in fitting 3 of support has a cross bar and two montants.Locating part 1 is the core component of fixed connecting piece, by structure and the integral rigidity of locating part 1, floating, the left and right displacement of cylinder in-core mould 4 is played to effective fixation.Depression bar 2 is arranged on intercostal bent angle 11 places of locating part 1, adopts common iron wire fixing with locating part 1, fix being connected of built-in fitting 3 and steel pipe support 7 by support, limits floating and a left and right sidesing shifting for in-core mould 4.The fixing built-in fitting 3 of support arranges cross bar above depression bar, montant is connected and tightens with steel pipe support 7 through the electric drill hole in template 6, plays effective restriction with locating part 1, common floating and the displacement to cylinder in-core mould 4, bottom surface reinforcing bar 5, local template 6 of depression bar 2.
As shown in Fig. 4, locating part is formed through angle-bender bending machining by Ф b4 cold drawn wire, and its height dimension h, width dimensions b, rib spacing size a determine according to the diameter of cylinder in-core mould with along cylinder rib width; The overall length L of member determines according to the arrangement length of concrete floor cylinder in-core mould.
As shown in Fig. 5, by 10 indented barss, through reinforcement cutting shears, cutting forms depression bar 2, and its length dimension L equals an arrangement length for in-core mould.
As shown in Fig. 6, the fixing built-in fitting 3 of support is processed through angle-bender, cutting machine by 6 round steel.
