Embodiment 1

[0055] Embodiment one sees Figure 1-4 As shown, this prefabricated concrete wall panel has a structural layer 1 and a protective layer 2 in sequence from the inside to the outside, the structural layer has a steel cage, the concrete of the protective layer 2 has a steel mesh, and the protective layer 2 The horizontal connecting steel bars 24 connected to the reinforcement mesh are connected to the structural layer 1, the left and right edges of the protective layer 2 protrude from the structural layer 1, the lower edge of the protective layer 2 extends downwards from the protrusion 7, and the top of the protective layer 2 protrudes upwards For the structural layer 1, the upper edge of the protective layer has a notch 8 corresponding to the notch of the adjacent precast concrete wall panel on the upper layer. When concrete is poured at the connecting joint between two adjacent prefabricated concrete wall panels, the protective layer 2 can serve as a template, which simplifies ...

Embodiment 2

[0062] Embodiment two see Figure 5 , the outer surface of the protective layer 2 is connected with an outer decorative layer 4, and the outer decorative layer 4 is a face brick, a paint or a decorative board.

[0063] The manufacture method of this prefabricated concrete wall panel, step 1, assembling bottom formwork; Step 2, place protective layer reinforcement mesh sheet on the bottom formwork, connect horizontal connecting steel bar 24 on reinforcement mesh sheet; Step 3, pour protective layer concrete; Step Four, before the initial setting of the protective layer concrete, insert the transverse connecting reinforcement 24 on the protective layer concrete; step five, integrally vibrate, make the transverse connecting reinforcing bar 24 and the protective layer concrete combine closely; step six, support the side form; step seven, Place reinforcement cages, reinforcement rings 15 and internal thread sleeves 9 on the protective layer. The reinforcement cages include transver...

Abstract

The invention relates to a precast concrete wallboard and a preparation method thereof. A wall body has a structural layer and a protection layer from inside to outside, wherein the structural layer is internally provided with a reinforcement cage, and a reinforcement fabric is arranged in the concrete of the protection layer; the protection layer is connected with the structural layer through a transverse connecting reinforcement connected to the reinforcement fabric; the left edge and the right edge of the protection layer protrude out of the structural layer; the lower edge of the protection layer downwards extends out of a protruded port; and the top of the protection layer upwards protrudes out of the structural layer; the upper edge of the protection layer has a dent corresponding to the protruded port of the adjacent precast concrete wallboard on the upper layer; and the two ends of a transverse bar of the reinforcement cage protrudes out of the left side surface and the right side surface of the structural layer of the wall body and form two rows of transverse steel ties bending inwards. The wallboard has the advantages that the construction process is simplified, the construction speed is accelerated, and the construction cost is reduced. Meanwhile, products precast by a factory have uniform specification and quality, and thus, the construction quality of a building structure can be guaranteed sufficiently. The precast concrete wallboard can be widely applied to construction of concrete steel buildings in building industry.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete wall panel and a manufacturing method thereof. Background technique [0002] The current residential construction adopts the method of pouring concrete on site. The on-site construction of the main structure of the external wall generally needs to go through the construction process of setting up formwork, laying steel bars, pouring concrete and then removing the formwork. After the main structure of the external wall is completed, the external decoration A series of tedious work such as floor construction and interior decoration construction. Each square meter of housing will cause energy consumption equivalent to 20 kg of standard coal, 0.05 cubic meter of water consumption, 3% loss of concrete, 3% loss of steel and 0.05 cubic meter of wood consumption. Calculated based on the currently commonly used rough house delivery model, during the renovation process, each household will bring about...
