Abstract

The utility model discloses a kind of fixed structures for pre-embedded steel slab in concrete, this structure includes pre-embedded steel slab ontology and the fixed steel bars set on the pre-embedded steel slab ontology back side, framework of steel reinforcement in the fixed steel bars and concrete welds, this structure further includes at least one spacer bar, and it is consistent and be vertical at the pre-embedded steel slab ontology back side that the spacer bar length and concrete thickness subtract pre-embedded steel slab body thickness.This structure facilitates setting of the pre-embedded steel slab in concrete structure, it is ensured that flatness and verticality of the pre-embedded steel slab relative to metope are installed convenient for subsequent members or equipment, and improve installation effectiveness.

Description

Fixed structure for pre-embedded steel slab in concrete
Technical field
The utility model relates to a kind of fixed structures for pre-embedded steel slab in concrete.
Background technique
Pre-embedded steel slab is for installing all kinds of components or equipment in concrete, as being used for placing all kinds of pipes in underground pipe gallery The gantry of line, gantry are fixed on pre-embedded steel slab.Usual pre-embedded steel slab is before concreting by being fixedly welded on reinforcing bar On skeleton, such fixed form is than the pre-embedded steel slab load-bearing capacity that previous concrete structure construction is installed again after the completion Greatly, and the globality of pre-embedded steel slab and concrete structure is preferable.Since position of the pre-embedded steel slab in concrete structure is difficult to Control, after concreting, pre-embedded steel slab is poor relative to flatness, the verticality of metope frequent occurrence, some are even prominent Metope or metope is fallen into out, seriously affects subsequent component or equipment installation.Therefore how efficiently pre-embedded steel slab to be fixed to In concrete structure, while also needing to guarantee that constructional appearance, flatness, verticality are influenced minimum to be that pre-embedded steel slab is fixed to coagulation Problem in soil structure.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of fixed structure for pre-embedded steel slab in concrete, This structure facilitates setting of the pre-embedded steel slab in concrete structure, it is ensured that pre-embedded steel slab is relative to the flatness of metope and vertical Degree is installed convenient for subsequent members or equipment, and improves installation effectiveness.
In order to solve the above technical problems, fixed structure of the utility model for pre-embedded steel slab in concrete includes pre-buried steel Framework of steel reinforcement in plate ontology and fixed steel bars set on the pre-embedded steel slab ontology back side, the fixed steel bars and concrete welds It connects, this structure further includes at least one spacer bar, and the spacer bar length and concrete thickness subtract pre-embedded steel slab ontology Consistency of thickness and it is vertical at the pre-embedded steel slab ontology back side.
Further, the spacer bar is three, and three spacer bars are triangular in shape to be vertical at the pre-buried steel The plate ontology back side.
Further, this structure further includes sealing piece, the sealing piece be set in the middle part of the spacer bar and with it is described pre- It is parallel to bury steel plate ontology.
Fixed structure due to the utility model for pre-embedded steel slab in concrete uses above-mentioned technical proposal, i.e. this knot Structure includes pre-embedded steel slab ontology and the fixed steel bars set on the pre-embedded steel slab ontology back side, in the fixed steel bars and concrete Framework of steel reinforcement welding, this structure further includes at least one spacer bar, and the spacer bar length is subtracted with concrete thickness Pre-embedded steel slab body thickness is consistent and is vertical at the pre-embedded steel slab ontology back side.This structure facilitates pre-embedded steel slab in coagulation Setting in soil structure, it is ensured that flatness and verticality of the pre-embedded steel slab relative to metope are installed convenient for subsequent members or equipment, And improve installation effectiveness.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is fixed structure schematic diagram of the utility model for pre-embedded steel slab in concrete;
Fig. 2 is the side view of Fig. 1.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, and fixed structure of the utility model for pre-embedded steel slab in concrete includes pre-buried Steel plate ontology 1 and fixed steel bars 2 set on 1 back side of pre-embedded steel slab ontology, the fixed steel bars 2 and the steel in concrete 6 Tendons skeleton 3 is welded, this structure further includes at least one spacer bar 4, and 4 length of spacer bar is subtracted with 6 thickness of concrete 1 consistency of thickness of pre-embedded steel slab ontology and it is vertical at 1 back side of pre-embedded steel slab ontology.
Preferably, the spacer bar 4 is three, three spacer bars 4 are triangular in shape be vertical at it is described pre-buried 1 back side of steel plate ontology.
Preferably, this structure further includes sealing piece 5, the sealing piece 5 be set to 4 middle part of the spacer bar and with it is described Pre-embedded steel slab ontology 1 is parallel.If pre-embedded steel slab is set to exterior wall concrete, sealing piece is added to sealing in spacer bar.
When pre-embedded steel slab is arranged in concrete, the framework of steel reinforcement in fixed steel bars and concrete is welded first, and just Step positioning pre-embedded steel slab ontology, is arranged two side template of concrete, and when two side templates closure, spacer bar plays two side forms of control The effect of plate spacing, while two side templates are respectively tight against pre-embedded steel slab ontology front and spacer bar free end, thus accurate school The position of positive pre-embedded steel slab ontology, flushes pre-embedded steel slab ontology front with template, to guarantee pre-buried steel when concreting Plate body position does not shift, and concrete plane and pre-embedded steel slab ontology front are in same plane after demoulding, really Flatness and verticality of the pre-embedded steel slab relative to metope are protected.
