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 tube in-core mould fixing means.
Background technology
The cast-in-situ reinforced concrete hollow floor is to receive force direction that the tube in-core mould of space is set on the edge, middle part, cross section of cast-in-situ floor, and the beam of structure generally secretly sets in plate, and floor becomes hollow-core construction behind the concreting; Compare weight reduction with common beam and slab structure, span increases, and sound insulation noise control effect improves; Reduce mould material and manpower consumption; For decoration facilitates, improved space availability ratio, therefore promoted rapidly in builing industry.
During the cast-in-situ hollow floor plate construction, emphasis to solve a problem: behind the location of tube in-core mould in floor, prevent single internal mold come-up and displacement, and prevent local come-up of floor bottom mould and reinforcing bar displacement, guarantee the construction quality of cast-in-place concrete hollow building roof.
Summary of the invention
The objective of the invention is provides a kind of cast-in-situ reinforced concrete hollow floor in order to solve the problem of above-mentioned tube in-core mould come-up and displacement.
Another object of the present invention provides a kind of in-core mould fixing means.
For realizing first goal of the invention, the technical scheme that is adopted is such: the cast-in-situ reinforced concrete hollow floor, comprise bottom surface reinforcing bar, tube in-core mould, template, steel pipe support, and it is characterized in that: it also comprises fixedly built-in fitting of locating part, depression bar and support; The locating part vertical sleeve is on tube 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; Support fixedly built-in fitting has a cross bar and two montants, and cross bar is above depression bar, and montant passes electric drill hole on the template and is connected to tighten with steel pipe support and is nested with above depression bar.
Further improve and be, said locating part is that steel pipe is bent into a plurality of continuous " Ω " shapes and forms.
For realizing second purpose; The technical scheme that is adopted is such: a kind of in-core mould fixing means; It is characterized in that: according to the appearance and size and the quantity of tube in-core mould; With steel pipe be bent into a plurality of continuous " Ω " thus shape becomes locating part, with its vertical sleeve on tube in-core mould, and with the fixing built-in fitting fixed limit spare of connecting rod and support.
Tube in-core mould fixed connecting piece forms the member of limiting displacement in the tube in-core mould upside and the left and right sides; Form integral body through fixed connecting piece and end muscle, gluten, support for shuttering, can prevent effectively that muscle is in concrete buoyancy and the perturbation action come-up and the displacement of generation down of vibrating at the bottom of single internal mold and the floor.This fixed connecting piece is made simple, easy for installation; And it is, all suitable to the tube in-core mould of all size through size adjustment to fixed connecting piece; Through the setting of fixed connecting piece, quality problems such as the iron wire fracture that can avoid adopting common iron wire to reinforce occurring in the measure of anti float, insufficient rigidity.

The specific embodiment
Referring to accompanying drawing.The cast-in-situ reinforced concrete hollow floor comprises locating part 1, depression bar 2 and support fixedly built-in fitting 3, tube 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, and is fixing with locating part 1; Support fixedly built-in fitting 3 has a cross bar and two montants.Locating part 1 is the core component of fixed connecting piece, through the structure and the integral rigidity of locating part 1, come-up, the left and right displacement of tube in-core mould 4 is played effective fixation.Depression bar 2 is arranged on intercostal bent angle 11 places of locating part 1, adopts with locating part 1 that common iron wire is fixing get final product, through fixing being connected of built-in fitting 3 and steel pipe support 7 of support, limits a come-up and a left and right sidesing shifting of in-core mould 4.Support fixedly built-in fitting 3 is provided with cross bar above depression bar; Montant passes electric drill hole on the template 6 and is connected with steel pipe support 7 and tightens, and jointly effective restriction is played in the come-up and the displacement of tube in-core mould 4, bottom surface reinforcing bar 5, local template 6 with locating part 1, depression bar 2.
As shown in Figure 4, locating part is formed through the angle-bender bending machining by Ф b4 cold drawn wire, and its height dimension h, width dimensions b, rib spacing size a confirm according to the diameter of tube in-core mould with along the tube rib width; The overall length L of member confirms according to the arrangement length of concrete floor tube in-core mould.
As shown in Figure 5, cutting forms depression bar 2 through reinforcement cutting shears by 10 indented barss, and its length dimension L equals an arrangement length of in-core mould.
As shown in Figure 6, support fixedly built-in fitting 3 is processed through angle-bender, cutting machine by 6 round steel.
