Description

A kind of precast concrete

Technical field

A kind of the invention belongs to prefabricated reinforced concrete structure technical field, more particularly to precast concrete component.

Background technology

In monolithic reinforced concrete structure work progress, field fabrication is more, and wet trade is more, has a large amount of form work engineerings, scaffold The intermediate links such as engineering, waste of resource pollute environment；Practitioner's quality, construction environment etc. affect very big, band to build guality The problems such as coming building performance, quality and durability.Change the status quo, precast concrete should be greatly developed, reduce scene system Make xoncrete structure amount, improve prefabricated rate.The primary structural member of precast concrete is made in factory, production efficiency High, quality is good, save resources and the energy, is conducive to sustainable development.It is building industrialization development using precast concrete Direction.

There is seam in precast concrete between prefabricated components, the faying face of seam crossing new-old concrete is weak ring Section, its stress performance determine integrality performance of the structure；Under load action, seam crossing can produce shear stress etc., it is easy to ftracture, slide Move, affect normal use.

Content of the invention

A kind of precast concrete of offer of the invention, solves to connect at component seam in traditional precast concrete The deficiency of weakness is connect, the prefabricated rate of precast concrete is improved.

A kind of precast concrete, it is characterised in that stretch out one or more vertical in the precast concrete side To concrete slab, horizontal hole on the concrete slab, is provided with.Hole is square hole, circular hole or other shapes.Use the concrete When overall structure built by native component, the vertical concrete plate of junction is interlocked with rear pouring concrete, be increased new and old mixed The binding ability of solidifying soil；Vertical concrete plate extend in rear pouring concrete and plays a part of shear key, improves switching performance；In advance The concrete slab that concrete component side processed is stretched out reduces pouring concrete consumption after seam crossing, improves the prefabricated rate of structure；After pour Concrete is included with precast concrete mutually, is locked together full of the hole on concrete slab, increases switching performance.Coagulation Thickness of the thickness of native plate less than precast concrete, concrete slab length, the width for stretching out precast concrete, thickness Determine Deng being required according to stress, production and construction etc..Reinforcing bar is configured with the vertical concrete plate.

Stretch out side, both sides of the vertical concrete plate in precast concrete side in the precast concrete side Or middle part；Determined according to stress, making and construction requirement.

The vertical concrete plate that the precast concrete side is stretched out is one or more columns per page, and each column concrete slab includes Two or more spaced less concrete slabs；I.e. each column vertical concrete plate includes that two or more are little mixed Concrete board.When overall structure is built with the precast concrete, can increase the effect of shear key, improve switching performance；Side Transverse steel is just set in the space between spaced concrete slab, and convenient construction improves connection reliability.

The precast concrete side is provided with embedded bar, and exposed parts are U-shaped or L-shaped or linear.With this When precast concrete builds overall structure, embedded bar exposed portion can increase the reliability of connection.

Precast concrete one or both sides plate face stretches out concrete thin plates, and the concrete thin plates are yi word pattern Or L-shaped.When being built into overall structure using the precast concrete, concrete thin plates can be convenient as the template of junction Construction.When hole being provided with the concrete thin plates, can increase connection reliability.

Groove is provided with the middle part of the precast concrete, is provided with hole on groove top concrete slab.Can be used for prefabricated Xoncrete structure T-shaped crossed node.

Groove is provided with the middle part of the precast concrete, and the precast concrete on the groove both sides stretches out concrete Plate.

Precast concrete proposed by the present invention can be used for shear wall structure or frame shear wall structure, basement, storage In material pond side wall, retaining wall, tunnel, the isostructural body of wall of pipeline；Can be used for floor, roof boarding, pipeline top board or base plate, tunnel Top board or base plate and other horizontal force components；Also can be used for other precast concretes, solve switching performance between component Not enough problem.

The present invention is had the advantage that compared with prior art.

(1) industrialized level is high：Precast concrete production efficiency height, good quality, save resources, be conducive to sustainable Development.

(2) using the present invention precast concrete build overall structure when, the precast slab of junction with rear Pouring concrete is interlocked, and increases the cementation of new-old concrete, realizes the effect of shear key, functional；Concrete Punch on plate, precast concrete and rear pouring concrete are locked together, i.e., rear pouring concrete is improve through first casting concrete The reliability of connection.

Specific embodiment

With reference to the accompanying drawings and examples, the precast concrete of the present invention is described in detail.

Precast concrete of the present invention is characterised by that one or more vertical concrete plates, institute are stretched out in its side State.Schematic diagrams of the Fig. 1 for the embodiment of the present invention 1.Stretch out 1 and mix in 1 side of precast concrete Concrete board 2, is provided with hole 3 on concrete slab 2.Thickness of the thickness of concrete slab 2 less than precast concrete 1, concrete The length of plate, quantity require to determine according to stress, production and construction etc.；The size and spacing of hole according to stress, produce and apply Work etc. requires to determine so as to can lock together with the rear pouring concrete in which.Hole 3 can be square hole, such as Fig. 1, or for circle Hole, such as Fig. 2, or other shapes hole.Concrete slab 2 is identical with 1 length of precast concrete, such as Fig. 1, or less than pre- Concrete component processed 1 length such as Fig. 3.

The vertical concrete plate 2 that 1 side of the precast concrete is stretched out can be the one of precast concrete side Side, both sides or middle part, require to determine according to stress, production and construction etc..Concrete slab 2 in the side of precast concrete 1, Such as Fig. 5；Or concrete slab 2 is in the both sides of precast concrete 1, such as Fig. 7；Or concrete slab 2 is in precast concrete structure The middle part of part 1, such as Fig. 1, Fig. 3；Or concrete slab 2 is respectively in the both sides and middle part of precast concrete 1, such as Fig. 8.
