The inside of braced frame 2 is fixed with wire mesh board 1, and braced frame 2's outside is fixed with first heated board 3, and the outside of first heated board 3 is covered with and exempts from board 4 of plastering, and the height of first heated board 3 is greater than braced frame 2 to make the top of first heated board 3 leak outside braced frame 2, the width of first heated board 3 is greater than braced frame 2's width, thereby makes the outside leak of at least one side of first heated board 3 outside braced frame 2. The dimensions of the plastering-free plate 4 are preferably the same as those of the first heat-preserving plate 3.
With respect to the support frame 2
The support frame 2 is a square frame-shaped support frame. The outer edge of the wire mesh sheet 1 is attached to the support frame 2. In the later construction process of the wall, the cast-in-situ concrete mortar passes through the steel wire mesh plate 1 and enters the supporting frame 2 to finish the filling of the supporting frame 2. In this process, the supporting frame 2 can well support the wire mesh plate 1, so that the wire mesh plate 1 is prevented from being deformed due to the impact of concrete mortar on the wire mesh plate 1. In addition, the steel wire mesh plate 1 can be used as a disassembly-free template, and the prefabricated assembly wall body can be formed after concrete mortar is poured.
The outer edge of the wire mesh sheet 1 may be directly attached to the support frame 2. The outer edge of the wire mesh sheet 1 may also be attached to the support frame 2 by: the inner side of the supporting frame 2 is also fixed with a first supporting rib 5 extending along the vertical direction, and the wire mesh plate 1 is clamped between the first supporting rib 5 and the supporting frame 2. The first support bar 5 is connected to the support frame 2.
With this structure, the supporting frame 2 is very light in weight, and convenient to transport and hoist. However, the non-plastering plate 4 is preferably fixed on the outer side of the first insulation plate 3. Thereby supporting the first insulation board 3. In addition, the constructed wall body is free of plastering on one side, so that the site construction speed is improved.
The support frame 2 is preferably a non-metallic material. Further preferred is a fiber reinforced composite (frp material). Thereby reducing the heat preservation performance of the precast slab with the beam column auxiliary heat preservation structure and reducing the energy consumption of the building by reducing the supporting frame as a cold-hot bridge. Can be formed by connecting four square nonmetallic tubes.
The support frame 2 may be provided with a second insulation board, that is, the second insulation board is filled in the space enclosed by the first insulation board, the support frame and the steel wire mesh board. The second heat insulation board has the following beneficial effects: 1. the wall body can be insulated; 2. the structural strength of the heat-preservation prefabricated wallboard can be improved; 3. the heat-insulating plate can be integrally formed with the first heat-insulating plate, so that the first heat-insulating plate is convenient to connect with the supporting frame; 4. the prefabricated wallboard is lighter in overall weight and convenient to hoist in later period.

Preferably, the cross section of the wire mesh sheet 1 is corrugated. The ripple is preferably a square wave, a triangular wave, or a trapezoidal wave, and more preferably a trapezoidal wave.
With respect to the first insulation board 3
The outer side of the supporting frame 2 can be further fixed with a second supporting rib extending along the vertical direction, and the second supporting rib is embedded into the first heat insulation plate 3. Thereby achieving or enhancing the connection of the support frame 2 with the first thermal insulation plate 3. The second support rib also has a supporting effect on the first heat preservation plate 3 for the support frame 2 which is the support frame 2. Preferably, the first support rib and the second support rib are opposite to each other. The structure of the support frame 2 allows the structure of the inner surface and the outer surface of the support frame 2 to be symmetrical, thereby reducing the manufacturing difficulty of the support frame 2 and improving the universality of the support frame 2. More importantly, the middle parts of the first supporting plate and the second supporting plate which are opposite to each other can be connected with each other, so that the supporting strength is improved. The middle parts of the first support plate and the second support plate are connected through a first support piece 13, and the first support piece 13 penetrates through the inner hollowed-out part of the support frame 2.
With respect to others
The first supporting ribs and the second supporting ribs can be square steel, U-shaped steel, steel pipes, triangular steel and the like. Preferably square steel, when the wire mesh sheet 1 has a trapezoidal wave shape, the width of the bottom of the square steel is preferably equal to the width of the bottom of the trapezoidal wave, thereby firmly pressing the wire mesh sheet 1 against the support frame 2. When the first support rib and the second support rib are U-shaped steel, the opening of the first support rib is preferably opposite to the support frame 2, and the opening of the second support rib is preferably opposite to the first heat insulation board 3.
Preferably, the support frame 2 may further be fixed with a transversely extending tendon pipe 6. The reinforcement pipe 6 plays a supporting role on the supporting frame 2, and deformation of the supporting frame 2 can be effectively reduced. More critical, the tendon-passing tube is preferably square tube or U-shaped steel. So that the transverse reinforcing steel 11 is inserted by using the inner cavity of the tendon passing tube. Through holes can be formed in the reinforcement pipe, so that concrete mortar can conveniently pass through the through holes and enter the reinforcement pipe.

At this time, the supporting frame 2 is provided with a through hole at the joint with the tendon-passing tube, and the wire mesh plate 1 is positioned at the inner side of the tendon-passing tube.
It is also possible that the tendon-passing tube is located outside the support frame 2, i.e. the outer side of the tendon-passing tube is connected to the inner side of the support frame 2. At this time, the wire mesh plate 1 is broken at a position where the tendon passing pipe is provided, and the broken position is abutted against the tendon passing pipe. The first support steel bar is disconnected at the position where the steel bar penetrating pipe is arranged, and the disconnected position is propped against the steel bar penetrating pipe.
The connection in the invention can be through a connecting piece 9 such as a buckle, a bolt, a rivet and the like, can be through binding steel bars, can be through welding and the like. The connection between the plastering-free plate 4 and the first heat-insulating plate 3 can also be through viscose.
The first support rib or support frame may be pre-formed with a diagonal brace pre-form 12 to connect the diagonal brace through the diagonal brace pre-form during construction to support the insulated prefabricated wall panel. The diagonal bracing preform is preferably located on the side facing away from the plastering-free plate. The diagonal bracing preform may be a preformed block structure. Or a notch, an opening or the like formed on the first supporting rib or the supporting frame. But also a protrusion or a pull ring or the like connected to the first support rib or the support frame.
Construction method for prefabricated assembled wall
The prefabricated wall is constructed in two ways, the first way is described in detail below, and the second way can be directly adopted by the scheme in the first way when the same or similar problems are encountered in the specific construction steps.
The first construction method is as follows:
step one, transporting the heat-preservation prefabricated wall board to a construction site, wherein the heat-preservation prefabricated wall board is an integral body. The heat preservation prefabricated wall board is connected directly or through a connecting piece 9, so that the plastering-free board 4, the first heat preservation board 3 (the second heat preservation board is arranged under a part of the structure), the steel wire mesh board 1 and the supporting frame 2 are formed into a whole. The plastering-free plate 4, the first heat-insulating plate 3 and the supporting frame 2 can be formed into a whole, and the steel wire mesh plate 1 can be additionally arranged after the plaster-free plate is transported to a construction site.
And step two, hoisting the heat-insulating prefabricated wall plate to a designated position, so that the base of the heat-insulating prefabricated wall plate is arranged on a floor slab, the top of the first heat-insulating plate 3 outside the supporting frame 2 is covered on one side surface of the beam, and the side of the first heat-insulating plate 3 outside the supporting frame 2 is covered on one side surface of the column 7. The sides of the partially prefabricated wall are not the columns 7 but the walls, in which case the side of the first insulation board 3 that is outside the support frame 2 is covered on the other wall. Thereby improving the heat insulation performance of the junction between the walls. The floor can be equipped with the recess of opening up in the position department that corresponds the prefabricated wallboard of heat preservation to utilize the position of the prefabricated wallboard of recess restriction heat preservation. In addition, the junction of the floor slab and the heat-preservation prefabricated wall board can be provided with a tongue-and-groove, so that not only can the pouring of concrete mortar be smoother, but also the connection between the floor slab and the heat-preservation prefabricated wall board can be tighter and firmer by filling the tongue-and-groove with the concrete mortar. Typically, the building has vertically extending through-length bars 10. The prefabricated wall panel that can keep warm is located on one side of the through-length steel bar 10. The support frame 2 may be composed of a first frame located at the top and extending in the horizontal direction, a second frame located at the bottom and extending in the horizontal direction, a third frame located at the left and extending in the vertical direction, and a fourth frame located at the right and extending in the vertical direction. The first frame and the second frame are provided with notches with openings deviating from the first heat insulation plate 3, and the through long steel bars 10 are clamped into the notches. It is particularly preferred here that the wire mesh sheet 1 is a wire mesh sheet 1 having a corrugated cross section, and that the openings in the first and second frames are such that the outer edges of the cross section of the first and second frames are corrugated as well, the corrugation of the wire mesh sheet 1 being in accordance with the corrugation of the first and second frames. The wire mesh plate 1 is clamped on the supporting frame 2, and the through-length steel bars 10 are positioned in the wave of the wire mesh plate 1. The wave of the wire mesh sheet 1 is preferably square wave, trapezoidal wave or triangular wave. Under the above two structures, the heat-preservation prefabricated wall board can be pushed into a designated position from one side, so that the building frame is allowed to be constructed first, and then the wall boards are installed layer by layer. The first frame and the second frame are provided with vertically penetrating and one-to-one right penetrating holes, and the long reinforcing steel bars 10 are inserted into the penetrating holes. During construction, the heat-preservation prefabricated wall board is lifted, then the through long steel bars 10 are sleeved into the through steel bar holes, and then the heat-preservation prefabricated wall board is slowly dropped down to the floor. And after the construction of the wall is finished, sequentially hoisting an upper floor slab and an upper heat-preservation prefabricated wallboard above the wall. In order to ensure the stability of the heat-preservation prefabricated wall board, an inclined strut can be arranged on the inner side of the heat-preservation prefabricated wall board, one end of the inclined strut is connected to the inclined strut prefabricated member, and the other end of the inclined strut is connected to the floor slab.
And thirdly, erecting a template on one side of the plastering-free plate 4 far away from the heat-preservation prefabricated wallboard. The template here may be a conventional template in which case the removal of the template in step five is required. The template can also be a dismantling-free template, the dismantling-free template comprises a supporting frame, the supporting frame is provided with a second steel wire mesh plate in a tensioning mode, and the mesh aperture of the second steel wire mesh plate is smaller than that of the first steel wire mesh plate; the second wire mesh sheet is embedded into the cast-in-place concrete slab. During construction, the disassembly-free template can limit the overflow condition of concrete mortar to the inner side. After the construction is finished, the disassembly-free template is not required to be removed, and plastering treatment is directly carried out on the constructed wall surface. The disassembly-free formwork can be connected to the prefabricated panels through the connecting pieces 9, and can also be connected to the through long steel bars or the transverse steel bars 11 through the connecting pieces 9. The support frame and the second wire mesh plate may be fixedly connected, and preferably, the second wire mesh plate is located at a side of the support frame away from the prefabricated plate. The supporting frame not only has the function of supporting, but also has the function of adjusting the thickness of the cast-in-situ concrete slab. The support frame and the second wire mesh plate can be detachably connected, and at this time, the second wire mesh plate is preferably tensioned at one side of the support frame, which is close to the precast slab. The supporting frame only has the function of supporting the second steel wire mesh plate, and is removed after the cement mortar is solidified.
