Description

A kind of two-sided overlapping wall system of ultra-high performance concrete without heat preservation

Technical field

The utility model relates to a kind of building field, the two-sided overlapping of specially a kind of ultra-high performance concrete without heat preservation Wall system.

Background technique

The core missions for promoting China's building industrialization development are to develop the structural body for agreeing with China's building industrialization development System.Precast concrete wall panel system is half prefabricated construction at this stage, is reinforced concrete wallboard system by scene It is poured into the transition assembled completely.Precast concrete assembled wallboard structural system and traditional shear wall wallboard structural system phase It is higher than with assembly degree, it is controlled convenient for quality, construction speed is fast, and the small environmental protection and energy saving of environmental pollution, cost is lower, industrialization Production level is high, substantially reduces the use of template in the construction process, will replaced using wall made of system construction There is powerful competitiveness and wide application prospect in terms of traditional wallboard casting system.But in the prior art, wallboard knot Structure system vertically connects mainly is arranged joint bar at seaming position, and will be in joint bar and prefabricated panel by rear pouring concrete Vertical reinforcement is indirectly connected with, to realize the transmitting of internal force.Since reinforcing bar cannot be directly connected to, structure ductility difference etc. is lacked Point causes vertical connecting portion to become the weak link of board-like wallboard structural system stress, and two-sided overlapping panel wall system is (without guarantor Temperature) structure is a kind of half prefabricated half cast-in-place concrete structure, it is good to have both the guaranteed and cast-in-place connection integrity of prefabricated components quality The characteristics of, it is the structure type for being suitble to one kind of housing industrialization new.Good integrity, rigidity is big, and anti-knock shock resistance is good, waterproof Property is good, to concave plane it is adaptable the advantages that, the structure ductility that can effectively solve assembled wallboard system is poor, vertically connects Weak problem is connect, it is significant in building trade field.

Utility model content

Purpose of the utility model is to solve wallboard structural system exists in the prior art and vertically connects mainly to exist Joint bar is set at seaming position, and is indirectly connected with joint bar and the vertical reinforcement in prefabricated panel by rear pouring concrete, To realize the transmitting of internal force.Due to the disadvantages of reinforcing bar cannot be directly connected to, and structure ductility is poor, vertical connecting portion is caused to become The weak link of board-like wallboard structural system stress, and the two-sided overlapping wall of a kind of ultra-high performance concrete without heat preservation proposed Body system.

To achieve the above object, the utility model provides the following technical solutions: including inside and outside two pieces of 20mm thickness UHPC wall Plate is provided with two-way single layer reinforced mesh in the UHPC wallboard, this two-sided composite wallboard is arranged in parallel and by vertically and horizontally stress Rebar cylinder mould is formed by connecting, and vertically and horizontally the both ends vertical reinforcement of stress steel bar stress cylinder mould stretches out in advance in two-sided prefabricated composite wallboard Making sheet both ends, and to the direction inclination perpendicular to plate face, the inclined direction of upper and lower side is on the contrary, inclination stretches out lengths of rebar on site Upper and lower interlaminar board intermediate node connection, so that the vertical reinforcement in upper and lower superimposed sheet in prefabricated board is connected in same rectilinear direction, Hole between two-sided prefabricated composite wallboard places equidistant positioning card, and poured in place concrete in junction.It is wherein two-sided Overlap precoated plate layer comprising vertically and horizontally stress steel bar stress cylinder mould and its UHPC on two sides layer, the vertically and horizontally steel bar stress The vertical reinforcing bar of both vertical reinforcement, transverse steel and connection that cylinder mould is mainly process by finished product machinery forms；Sandwich layer is built, Its in the UHPC layer on two sides cast in situs ad eundem normal concrete, and in two-sided prefabricated composite wallboard in length and breadth To the integrated poured one of steel bar stress.The preformed layer UHPC thickness be only normal concrete preformed layer thickness three/ One, the utility model construction cost, installation and transportation, structure stress, factory production, in terms of function and effect it is significant It improves.

Preferably, in the note sandwich layer and the two-sided overlapping precoated plate layer of UHPC steel mesh using self-compacting concrete casting one Body.

Preferably, steel bar stress cylinder mould section is solid rectangle, and vertically and horizontally steel mesh is welded to connect in vertical for connection.

Preferably, the nothing of the two-sided overlapping precoated plate layer of the UHP vertically and horizontally does hair pulling treatment at reinforcing bar, and plucking height is not Less than 5mm, in addition the advantageous effect of steel bar stress cylinder mould, it is ensured that the shearing resistance requirement of superposed surfaces.

Preferably, the thickness of the two-sided overlapping precoated plate layer of the UHPC be only normal concrete preformed layer thickness three/ One, but the ability to work of the mechanical property of its superelevation, the endurance quality of superelevation, construction cost, installation and transportation, structure by Power, factory's production, energy conservation and environmental protection etc. function and effect significantly improve.

Preferably, the splicing between the two-sided overlapping precoated plate layer prefabricated board of the UHPC is all and stretches out to indulge in superimposed sheet end To reinforcing bar longitudinal lap joint in another overlapping plate, then integrated poured concrete, can effectively solve fabricated shear wall plate The problem that structure ductility is poor, vertical connection is weak.

Compared with prior art, the utility model has the beneficial effects that the utility model is mixed without the very-high performance of heat preservation Amount of reinforcement is greatly saved by using the vertically and horizontally reinforcing bar flexible arrangement of finished product in the solidifying two-sided overlapping wall system of soil, economical Property it is good, scene does not need formwork supporting plate when construction, due to the setting of the vertically and horizontally steel bar stress of finished product, so that on-site hoisting and folded Reinforced bar engineering is simple, accurate in plywood, and speed of application is fast, is conducive to shorten the construction period, using UHPC as two-sided preformed layer, Replace thicker coagulation by relatively thin prefabricated double plates using the mechanical property of UHPC superelevation, the ability to work of the endurance quality of superelevation In the case that native prefabricated board is conducive to the power transmission between plate, while construction workload increases seldom at the scene, it is possible to reduce reinforcing bar Dosage realizes being directly connected to for vertical reinforcement, to enhance the strength and stiffness of plywood junction stacked on top of one another, significantly improves knot The stress performance of structure, steel bar stress cylinder mould can manufacture in factory process, and prefabricated board is industrialized in factory for prefabrication and made Make, can guarantee construction quality, be conducive to save manpower, be beneficial to energy conservation environmental protection, advantageously reduce construction cost, saves construction money Gold.
