Abstract
The invention discloses a concrete prefabricated part. The strip concrete prefabricated part comprises a bottom plate and two beads, wherein the bottom plate and the beads are integrally connected. The concrete prefabricated part is characterized in that the cross section of the concrete prefabricated part is of a double-T shape, reinforcing steel bars are embedded in the concrete prefabricated part in the length direction, and two ends of each reinforcing steel bar extend out of the concrete prefabricated part; the two beads are arranged in parallel on the bottom plate, and a plurality of through holes penetrating through the beads are alternately formed in the beads in the length direction. The concrete prefabricated part provided by the invention can solve the problem of insufficient rigidity and strength of a conventional concrete prefabricated part, and the construction cost is lowered while the construction time is shortened.
Description
Technical field
the present invention relates to a kind of buiding material members, be specifically related to a kind of concrete precast element.
Background technology
in the construction process of the buildings such as house, bridge, for strengthening the intensity of building, use in a large number reinforced concrete structure, the general mode that adopts a module and cast-in-situ, need to adopt template scene to support to model, then by pouring concrete to maintenance moulding in model.Existing, water in injection-molded, exist and expend height, long shortcoming of engineering time, and existing double-T shaped solidifying native prefabricated component exists Rigidity and strength not enough.
Summary of the invention
technical problem to be solved by this invention is just to provide a kind of concrete precast element, solves the Rigidity and strength deficiency that concrete precast element exists, and can reduce construction cost, reduces the engineering time.
for solving the problems of the technologies described above, technical scheme of the present invention is: a kind of concrete precast element, described concrete precast element is elongated, comprise base plate and two fins, base plate is connected with fin one, described concrete precast element cross section is double-T, is embedded with along its length reinforcing bar in described concrete precast element, and solidifying native prefabricated component is extended at reinforcing bar two ends; Described two fins are arranged in parallel on base plate, and described fin is interval with several through holes that connects fin along its length.
as preferably, described fin upper end cross section is circular arc.
as preferably, between described two fins, be provided with some reinforcing ribs.
beneficial effect of the present invention: the invention provides a kind of concrete precast element, can solve the Rigidity and strength deficiency that concrete precast element exists, and can reduce construction cost, reduce the engineering time.
Accompanying drawing explanation
fig. 1 is the structural representation of embodiment.
fig. 2 is the cross-sectional view of embodiment.
in figure, 1-base plate; 2-fin; 3-reinforcing rib; 4-through hole; 5-reinforcing bar.
The specific embodiment
the following stated is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
embodiment: with reference to the accompanying drawings, a kind of concrete precast element, elongated, comprise base plate 1 and two fins 2, base plate 1 and fin 2 are integrated connection, and its cross section is double-T, its inside is embedded with reinforcing bar 5 along its length, and concrete precast element is extended at reinforcing bar 5 two ends.Article two, fin 2 is arranged in parallel on base plate 1, and fin 2 is interval with along its length several 2 of 4, two fins of through hole that connect fin and is provided with some reinforcing ribs 3.
during construction, a plurality of concrete precast element base plates 1 are held between building straight wall down side by side, then adopting respectively reinforcing bar to run through each concrete precast element arranges in the every exhausting hole 4 forming, two ends are strained and fixed, in concrete precast element surrounding installation side template, carry out second pouring, each concrete precast element is connected into an integral body, can form floor slab structure.In concrete precast element, extend outward the reinforcing bar 5 at two ends for being connected with straight wall cast.This pouring type greatly reduces the demand of mould and the complexity of formwork, and can improve greatly whole intensity and anti-seismic performance after being strained and fixed by reinforcing bar.Fin 2 upper end cross sections are in the arc-shaped, reduce one deck reinforcing bar and concrete precast element contact area for guaranteeing that backplate surface intensity is laid when second pouring, avoid forming cavity when second pouring and affect intensity.Article two, 2 of fins are provided with some reinforcing ribs 4, can greatly strengthen the rigidity of concrete precast element, improve supporting capacity.
