In addition, the products precast in factory are consistent in specification and quality, the construction quality of building structure can be fully guaranteed, and the wallboard can be extensively applied to the construction of reinforced concrete buildings in the construction industry.

The invention discloses a thermal insulating wall surface system and a breeding room. The thermal insulating wall surface system and the breeding room are mainly designed for solving the problems that in the prior art, a wall surface and a roof are poor in thermal insulation, not good in ventilation effect and the like. The thermal insulating wall surface system comprises stand columns and a wall surface arranged on the stand columns. The wall surface comprises connecting purline, and an outer thermal insulating wall surface body and an inner thermal insulating wall surface which are connected to the two sides of the connecting purline respectively. The connecting purline is connected to the stand columns. The inner thermal insulating wall surface is of an inner flush structure.

The invention relates to a construction process, especially relates to a process for constructing joints between the bottom of a window on an outer wall and the inside as well as outside of a windowsill. The process provided by the invention comprises the following steps: on a windowsill at the outside of the bottom of the window, performing direct outward insulating base layer (consisting of cement mortar screeding layers) to falls, wherein the peak of a slope is arranged at the position 1 / 3 away from the inner edge of a window frame; filling the bottom of the external window frame with polyurethane foams; after the external window frame of a building is installed, inserting an XPS insulation board at the outside of the bottom of the window into the bottom of the window; and then foamingfrom the indoor. Because the peak of the slope is arranged at the position 1 / 3 away from the inner edge of the window frame, the infiltrating positions of sealants are gaps between the outer edges ofthe window frame and outside surface mortar, and the outer sides; a joint seam between an insulation board at the horizontal plane of the external windowsill and an insulation board at the vertical plane of the external windowsill is a horizontal joint seam; and the height of the inside (completely closed up) of the windowsill is 10 mm higher than the taken outside of the windowsill. The process provided by the invention can control the water leakage phenomenon of the windowsill of the external window of a building better under the premise of guaranteeing no thermal bridge occurs.

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.

The invention provides a reinforced composite plate for external wall insulation, an integrated structure of an insulation wall body and a construction method. The reinforced composite plate for external wall insulation comprises a reinforced insulation plate and a light-weight concrete poured and compressed protection layer, wherein the reinforced insulation plate comprises two parallel rebar welded mesh sheets A and B with same size and same shape and an insulation plate; the mesh sheets A and B are respectively arranged on both sides of the insulation plate and are welded and fixed by connecting rebars; a fixing sheet is arranged between the mesh sheet A and the insulation plate; the protection layer with a certain thickness is arranged on the other side of the insulation plate; grooves or skewed slots of 5 to 10 mm are formed around the protection layer. During construction, the rebar welded mesh sheet A in the reinforced composite plate for external wall insulation is arranged in an external wall and is connected with a main bar, a stirrup and a structural tiepiece in the external wall through fine tie bars or an enough anchoring length is left in the external wall body. The reinforced composite plate for external wall insulation manufactured by the method is convenient to manufacture and mount, has obvious insulation and fireproofing effects, and is convenient to construct; the service life of the reinforced composite plate is the same as that of a structure.

The invention discloses a waterproof and heat-preservation construction method for building water supply and drainage and heating engineering. The method comprises the steps that firstly, a building water supply and drainage and heating engineering pipeline and sanitary ware are installed; the sanitary ware is fixedly installed on a floor through a foundation bolt, the floor is a cast-in-place concrete floor, and after construction is finished, water proofing and corrosion proofing are conducted on the foundation bolt; secondly, according to water proofing and heat preservation treatment of the pipeline, water proofing and heat preservation treatment are conducted on the pipeline needing to be installed, a pipeline section, penetrating through the floor, in the pipeline needing to be installed is a floor penetrating pipeline section, a pipeline section, penetrating a wall, in the pipeline needing to be installed is a wall penetrating pipeline section, and a pipeline section, located outside the wall and the floor, in the pipeline needing to be installed is an exposed pipeline section.
