Abstract
The utility model relates to a prestressed concrete prefabricated hollow wall plate, particularly an enclosing and protective wall plate used in outer walls of construction in single-layer or multiple-layer concrete frame structure, steel structure, etc. The utility model is added with upper layer prestressed steel hinging wires and steel reinforcement or steel wires on the basis of prestressed steel hinging wires and steel reinforcement or steel wires which are only assembled at the bottom of the plate. The middle part of the wall plate has a hollow part. Iron pieces which are buried in advance can be respectively arranged at the bottom and the surface of the plate according to the need of the connection of nodes. The shape of the wall plate is divided into a flat opening shape, a groove shape, a pin and key shape, etc. for improving connecting effect. The utility model has the advantages of big width of span, high intensity, simple installation process, high construction speeds, high mechanization degree and land saving. The utility model conforms to the developing direction of the improvement of construction.
Description
Technical field
The utility model relates to a kind of prestressed concrete precast hollow wallboard.
Background technology
In order to economize the land resource, country has progressively limited the use of loam brick until forbidding.Building unit is prefabricated then to be the direction of architectural development always.Adopt common concrete block masonry building enclosure body of wall, the construction plant area occupied is bigger, the difficult control of complex process, quality, and particularly speed of application is slow, and mechanization degree is very low.Adopt common wallboard as safeguarding body of wall, span is little, and intensity is low, generally only as interior partition.Prestressed concrete precast hollow wallboard has the advantage that span is big, intensity is high, and its mounting process is simple, and speed of application is fast, and the mechanization degree height had not only been saved the soil, but also met the developing direction of architecture advancement.
Summary of the invention
The technical problems to be solved in the utility model provides the external wall that a kind of speed of application is fast, construction technology is simple, span is big, intensity is high and goes along with sb. to guard him wallboard.
For addressing the above problem, prestressed concrete precast hollow slab of the present utility model, comprise upper strata, lower floor's prestress wire, reinforcing bar or steel wire, because the double-deck arrangement of reinforcement of plate, make intensity, the span of wallboard improve very big, originally the stressed hollowcore slab of single face can be two-sided stressed, thereby satisfy the wallboard force request.
The hollow parts of wallboard both can satisfy the requirement of the default pipeline of building, the deadweight that has alleviated plate again.By improvement, can produce the matched boards that a side is recessed, opposite side protrudes to side template; Both sides all are the flat oralias on plane; The plate of pin key oralia that both sides are recessed and the recessed side plane of a side.Simultaneously, can at the bottom of Ban Ding, plate, add built-in fitting in case of necessity, make that wallboard connects flexibly, speed of application is fast.
Description of drawings
Fig. 1 is a matched boards, and the recessed opposite side of a side protrudes;
Fig. 2 is the plate of the recessed side plane of a side;
Fig. 3 is the flat oralia on plane for both sides;
Fig. 4 is all recessed pin key oralias in both sides.
Fig. 1 one Fig. 4 is prestressed concrete precast hollow wallboard.
Stain is depicted as pressure zone and tensile region reinforcing bar, steel wire or steel strand among the figure, and circular hole is depicted as hollow parts.
The specific embodiment
Prestressed concrete precast hollow wallboard can by at the bottom of the plate, the embedded iron parts of plate face is connected on the members such as the beam of steel column, girder steel, steel concrete, post, also can directly be connected with steel column, girder steel, reinforced concrete beam, post, forms space enclosing structure.
Claims (3)
1, a kind of single or multiple lift concrete frame structure that is applied to, the prestressed concrete precast hollow wallboard that external walls such as steel work are gone along with sb. to guard him, it is characterized in that: comprise the upper strata, lower floor's prestress wire, reinforcing bar or steel wire, steel strand, reinforcing bar or steel wire are wrapped in the concrete of prestressed concrete precast hollow wallboard, there is hollow parts at prestressed concrete precast hollow wallboard middle part, connect needs according to node, can be at the bottom of the plate of prestressed concrete precast hollow wallboard, the plate face is provided with embedded iron parts respectively, and prestressed concrete precast hollow wallboard side is divided into flat mouthful, tongue and groove, three kinds of shapes of pin key mouth.
2, according to the described prestressed concrete precast hollow of claim 1 wallboard, it is characterized in that: described upper strata, lower floor's prestress wire, reinforcing bar or steel wire are arranged at concrete compression district and pressure zone.
3, according to the described prestressed concrete precast hollow of claim 1 wallboard, it is characterized in that: described prestressed concrete precast hollow wallboard hollow parts can change hollow shape.
