Description

A kind of antidetonation coupling beam component and the anti-seismic prefabricated shear wall with hole

Technical field

The utility model belongs to technical field of building construction, more particularly to a kind of antidetonation coupling beam component and the antidetonation with hole Precast shear wall.

Background technology

Coupling beam is the key member of each wall limb of connection composition shear wall body.Experimental study shows:The span-depth radio of coupling beam Its mechanical property same Vierendeel girder when more than 5, coupling beam is based on bending failure no more than 5 and when being more than 2.5 for span-depth radio, and span-depth radio is not Its damage -form is failure by shear when more than 2.5 (shearing slip destroys, shears diagonal tension failure), wherein bending failure and shearing Sliding rupture has certain ductility, and shears diagonal tension failure then almost without ductility.

In Practical Project, coupling beam generally has depth of section big, the small feature of span, especially in fabricated shear wall In the building of structure, exterior wall generally uses the precast facade of whole concrete, for example is originally used for the breast whole of masonry filler wall Concrete walls have been changed to, have actually increased even depth of beam in this way, span-depth radio is very small, and rigidity is very big；Therefore its coupling beam Damage -form be failure by shear, ductility is very low, is unfavorable for consuming energy, very unfavorable to the shockproof requirements of building.

The basic demand of Design of Connecting Beam is:1) under " small shake " and wind action, in elasticity or basic elastic working State.2) under " middle shake ", as the first line of defence of even limb seismic structural wall, earthquake resistant wall, there is plastic hinge in coupling beam both ends, should be by " cutting by force weak It is curved " principle make beam-ends occur bending surrender plastic hinge, with the seismic energy that dissipates.By the design principle of " strong wall limb, weak girts ", make The surrender of coupling beam is prior to wall limb and wall limb is made to form more hinge bodies, has larger ductility.3) under " big shake ", allow coupling beam It destroys.

Utility model content

For the technical problem that the anti seismic efficiency of coupling beam existing in the prior art is poor, the utility model provides a kind of anti- Coupling beam component and the anti-seismic prefabricated shear wall with hole are shaken, to improve shock resistance.

In order to solve the above technical problems, the technical solution adopted in the utility model is：

A kind of antidetonation coupling beam component, including multilayer coupling beam, every layer of coupling beam include prefabricated components and flexible separate layer, The flexibility separate layer is horizontally disposed, and the flexibility separate layer is fixed by multiple PE sticks for wearing flexible separate layer, the PE The both ends difference bondage of stick on the steel reinforcement cage of the prefabricated components of adjacent two layers coupling beam, the flexible partition layer, prefabricated components and PE sticks are coated with concrete layer.

Preferably, the flexibility separate layer is fabricated from a flexible material.

Preferably, the flexible partition layer is EPS sheet.

A kind of prefabricated seismic shear wall with hole, including multiple prefabricated wall limbs, adjacent two prefabricated wall limbs it Between shear wall body connected by antidetonation coupling beam component as described in any one of claims 1 to 3.

Preferably, between the prefabricated wall limb of the antidetonation connection component and upper layer and be respectively provided between lower layer prefabricated wall limb There is last layer.

Compared with prior art, advantageous effect possessed by the utility model is：Antidetonation coupling beam group in the utility model Structure is simple and easy to implement for part, is applied to reduce the rigidity of coupling beam component in precast shear wall, increases the consumption of coupling beam component Can ability, ensure that coupling beam component is under elasticity or basic elastic stage under small shake, and make coupling beam group under middle shake (big shake) Part is surrendered prior to prefabricated wall limb, to form more hinge bodies, be ensure that structure has larger ductility, has been reached energy-dissipating and shock-absorbing Effect.

Specific implementation mode

So that those skilled in the art is better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings and is embodied Example elaborates to the utility model.

As depicted in figs. 1 and 2, the embodiments of the present invention disclose a kind of antidetonation coupling beam component, including multilayer coupling beam, Every layer of coupling beam includes prefabricated components and flexible separate layer 3, and flexible separate layer 3 is horizontally disposed, and flexible separate layer 3 is worn by multiple If the PE sticks 4 of flexible separate layer 3 are fixed, PE (High Density Polyethylene), Chinese is polyethylene stick, PE Stick 4 is that a kind of crystallinity is high, nonpolar thermoplastic material, has good heat resistance and cold resistance, chemical stability is good, also With higher rigidity and toughness, mechanical strength is good.The both ends of PE sticks 4 are respectively by 5 bondage of tied silk in adjacent two layers coupling beam On the steel reinforcement cage of prefabricated components, flexible partition layer 3, prefabricated components and PE sticks 4 are coated with concrete layer.Flexible separate layer 3 is by soft Property material is made, such as EPS sheet etc..

When antidetonation coupling beam component is factory produced, when assembling reinforcement, installs flexible separate layer 3 together, using PE sticks 4 pass through flexible separate layer 3 to be fixed, and by the binding of PE sticks on steel reinforcement cage, then casting concrete, concrete wrap soft Property separate layer 3.Big coupling beam has been divided into the small coupling beam of multilayer as a result,.

Antidetonation coupling beam component advantage is：One, is embedded to flexible separate layer 3 in the prefabricated component of factorial praluction, difficulty compared with Low, precision is higher, can play the advantage of batch production；Two, are separated coupling beam using flexible separate layer 3, and thermal coefficient is low, The generation of cold bridge (heat bridge) is prevented；In three, flexibilities separate layers, 3 Transducers Embedded in Concrete layer, by the protection of concrete layer, not rapid wear It is bad；Four, flexibilities 3 rigidity of separate layer are very low, have carried out effective separation to coupling beam, so that it is divided into multiple small coupling beams, and when earthquake The deformation that coupling beam can fully be discharged, to coupling beam substantially without constraint.

The embodiments of the present invention also disclose a kind of prefabricated seismic shear wall with hole 1, including multiple dry walls Limb connects into shear wall body between adjacent two prefabricated wall limbs by antidetonation coupling beam component as described above.Antidetonation connects It is both provided with last layer 6 between the prefabricated wall limb of component and upper layer 2 and between lower layer prefabricated wall limb 2.Upper layer component and in-situ layer 6 Intersection be not provided with bar connecting.

Above example is only the exemplary embodiment of the utility model, is not used in limitation the utility model, this practicality is new The protection domain of type is defined by the claims.Those skilled in the art can be in the essence and protection domain of the utility model It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling new in this practicality In the protection domain of type.
