Technical field:
the utility model relates to a kind of interior concrete folding plate of using 180 ° of curved anchors connections of reinforcing bar of span that is suitable for housing industrialization.
Background technology:
in order to solve existing precast concrete superimposed sheet because of oversize, the problem of transportation and inconvenient installation need be taken it apart making, on-site consolidation connection.It is the processing of ater-casting that the assembly unit of precast concrete superimposed sheet in span connects key, and conventional method is through reinforcing bar welding or mechanical connection, but linker is complicated, cost is higher, and the reliability that connects is difficult for guaranteeing.To have a strong impact on precast concrete portion article---the extensive use of superimposed sheet like this.
The utility model content:
The purpose of the utility model has provided a kind of no longer complicated program and plant equipment of needs that make when splicing between the superimposed sheet, makes the precast concrete that the reinforcing bar link cost significantly reduces, performance is significantly strengthened
The superimposed sheet that splice in span
.
Above-mentioned purpose realizes through following technical scheme:
Use the concrete folding plate that 180 ° of curved anchors of reinforcing bar connect in
a kind of span; Its composition comprises: precast concrete superimposed sheet body; Described two precast concrete superimposed sheet bodies splice a side and are connected by the U shaped steel muscle that 180 ° of curved anchors of reinforcing bar form; Form the ater-casting between the U shaped steel muscle that a group connects; The U shaped steel muscle upper corners at place, described ater-casting is inserted vertical elongated reinforcing bar, and floor steel bar stress, described ater-casting concreting are laid in the U shaped steel muscle bottom at place, described ater-casting.
Use the concrete folding plate that 180 ° of curved anchors of reinforcing bar connect in
described span; Described precast concrete superimposed sheet body all around side all has the straight reinforcing bar that exposes; The straight reinforcing bar in the side that will connect in the erecting bed curves U shaped steel muscle, and described U shaped steel muscle is anchored at place, described ater-casting; Described precast concrete superimposed sheet body upper surface is a pitted skin.
Beneficial effect:
Use the concrete folding plate method that 180 ° of curved anchors of reinforcing bar connect in
span that 1. the utility model is realized; Solved because of the precast concrete superimposed sheet oversize; The problem of transportation and inconvenient installation is for the application that advances the housing industrialization member provides a kind of effective ways.
Use the concrete folding plate method that 180 ° of curved anchors of reinforcing bar connect in
span that 2. the utility model is realized; Lot of reinforcing steel bar welding or mechanical connection program have been simplified; Only need simple manual operations to accomplish, meet housing industrialization precast concrete construction construction characteristics.
3. the utility model jointing positions superimposed sheet connect through the U shaped steel muscle that overlaps; U shaped steel muscle upper corners is inserted vertical elongated reinforcing bar; The bottom is laid floor and is designed original steel bar stress, and under the parcel of U shaped steel muscle, similar dark beam action is played in elongated ater-casting; Effectively strengthen the superimposed sheet anti-bending bearing capacity, lap length has realized the Stress Transfer between reinforcing bar; The superposed surfaces place carries out pitted skin and handles, and can transmit interface shear stress reliably, can fully ensure the overall performance of connected precast concrete superimposed sheet after therefore connecting.
4. simple, the construction quality of the construction technology of the utility model are easy to guarantee, improve the labor productivity of precast unit production and transport, improve the total quality of dwelling house, reduce cost, and cut down the consumption of energy.
5. the precast concrete superimposed sheet body upper surface of the utility model are made into pitted skin, are beneficial to the globality of concrete secondary cast.
6. the U shaped steel muscle connection of the utility model employing make the connection between the precast concrete superimposed sheet more firm; Form an integral body between the precast concrete superimposed sheet after connecting, strengthened the intensity of splicing precast concrete superimposed sheet.

The specific embodiment:
Embodiment 1:
Use the concrete folding plate that 180 ° of curved anchors of reinforcing bar connect in
a kind of span; Its composition comprises: precast concrete superimposed sheet body 1; Described two precast concrete superimposed sheet bodies splice a side and are connected by the U shaped steel muscle 2 that 180 ° of curved anchors of reinforcing bar form; Form ater-casting 3 between one group of U shaped steel muscle that connects; The U shaped steel muscle upper corners at place, described ater-casting is inserted vertical elongated reinforcing bar 4, and floor steel bar stress 5, described ater-casting concreting 6 are laid in the U shaped steel muscle bottom at place, described ater-casting.
Embodiment 2:
Use the concrete folding plate that 180 ° of curved anchors of reinforcing bar connect in
embodiment 1 described span; Described precast concrete superimposed sheet body all around side all has the straight reinforcing bar 7 that exposes; The straight reinforcing bar in the side that will connect in the erecting bed curves U shaped steel muscle, and described U shaped steel muscle is anchored at place, described ater-casting; Described precast concrete superimposed sheet body upper surface is a pitted skin 8.
Embodiment 3:
Use the splicing preparation method of the concrete folding plate that 180 ° of curved anchors of reinforcing bar connect in
a kind of span, precast concrete superimposed sheet body has that to carry out the U shaped steel muscle that side that horizontal direction connects exposes be bottom steel bar stress in floor is striden; U shaped steel muscle is anchored at the place, ater-casting that reserves elongated setting, and the ater-casting is in U shaped steel muscle upper corners and inserts vertical elongated reinforcing bar, and the bottom is laid floor and designed original steel bar stress; Precast concrete superimposed sheet body upper surface is made into pitted skin, is beneficial to the globality of concrete secondary cast; Precast concrete superimposed sheet body piece bottom installs template, and the precast concrete superimposed sheet bottom of two splicings is provided with support, and concreting connects into integral body with two precast concrete superimposed sheets after maintenance.
Embodiment 4:
Use the splicing preparation method of the concrete folding plate of 180 ° of curved anchors connections of reinforcing bar in
