The invention provides a sandwich heat preservation floor slab and a forming method thereof and a prefabricated slab for the sandwich heat preservation floor slab, and belongs to the field of heat preservation composite floor slabs, the sandwich heat preservation floor slab at least comprises two prefabricated slabs, the two prefabricated slabs are closely spliced and laid on a structural beam to achieve support-free, and a bottom plate part, to be poured, of the floor slab is formed. The prefabricated plate comprises prefabricated bottom plate layers and heat preservation layers, the heat preservation layers are formed on the prefabricated bottom plate layers, plate edges of the adjacent prefabricated bottom plate layers are closely spliced to form splicing seams, connecting grooves are formed in the positions, close to the splicing seams, of the heat preservation layers, notches of the connecting grooves in the adjacent heat preservation layers are opposite, and lap joint pieces are arranged in the connecting grooves of the adjacent heat preservation layers in a lap joint mode. A cast-in-place layer is formed on the heat preservation layer in a pouring mode, the cast-in-place layer at least covers the lap joint pieces, and the connecting grooves are filled with the cast-in-place layer to form a three-layer sandwich structure with the prefabricated bottom plate layer, the heat preservation layer and the cast-in-place layer.

The utility model discloses a buried natural smoke vent structure which comprises a garage free face natural smoke vent and a garage top natural smoke vent, the garage free face natural smoke vent is communicated with the interior of a garage through a first switching channel, and a vertical shaft is arranged at the garage top natural smoke vent. And the vertical shaft is communicated with the interior of the garage through the second switching channel. The problems that an existing basement free face natural smoke outlet is not high enough, and a natural smoke outlet in the top of a garage greatly influences landscape arrangement of a garage top plate are solved.

The application relates to the technical field of fireplaces, in particular to a high-efficiency heat-dissipation fireplace. The fireplace comprises a furnace body, the furnace body comprises a back plate, a side plate, a bottom plate, a front plate, a top plate and a combustion inner cavity, the top plate is composed of a plurality of convex units, and the plurality of convex units are connected in a wave shape. The top plate is arranged in a wave shape, the periodic fluctuation can increase the effective height of the top plate in the thickness direction, the geometric rigidity is enhanced, the top plate is prevented from being deformed due to heat, and the surface area of the wave-shaped top plate is increased, so that the heat-dissipation area of the top plate is effectively increased.

The invention discloses a prefabricated concrete canopy and a connecting node of the prefabricated concrete canopy and a modular structure main body, the prefabricated concrete canopy comprises a bottom plate, a side turning edge and a vertical turning edge, the side turning edge is provided with an anchoring steel bar, the connecting node comprises the prefabricated concrete canopy and the modular structure main body, the modular structure main body is provided with an anchoring hole site, and the modular structure main body is provided with an anchoring hole site. One end of the anchoring steel bar extends into the anchoring hole position to be connected with the modular structure body. The canopy is designed to be a beam type stress component, the bottom plate of the canopy is designed to be a simple supporting plate supported on the side face turning edges, the thickness can be very thin, the weight of the canopy is greatly reduced, and the effective height and the stress performance of the bending section are greatly improved. The number of ribs exposed out of the canopy is small, components are light, the structural body does not contain components protruding out of the module in the prefabrication stage, and mold machining and component production are convenient. The connecting node of the structure main body and the canopy is simple in structure, the time for connecting the structure main body and the canopy to form an integral firm body on site is short, the canopy temporary support can be dismantled one day after installation, and the construction efficiency is high.

The invention discloses a reinforcing structure based on UHPC (Ultra High Performance Concrete), and relates to the technical field of repairing and reinforcing of original buildings. The strength and the stability of the integral structure formed by the reinforced structure and the workpiece are improved through the ultra-high performance concrete; the first reinforcing unit is located in the UHPC; the first reinforcing units and the UHPC can bear external loads together and deform together under the action of the external loads, and the flexural rigidity, the shear strength and the bearing capacity of an overall structure formed by the reinforcing structure and a workpiece are remarkably improved; the first end of the second reinforcing unit extends into the ultra-high-performance concrete, the second end of the second reinforcing unit extends into the workpiece, the binding force and integrity between the workpiece and the ultra-high-performance concrete are improved, the rigidity of an overall structure formed by the reinforcing structure and the workpiece is improved, the first reinforcing unit abuts against the second reinforcing unit, and therefore the reinforcing effect is improved. It is guaranteed that the overall structure formed by the reinforcing structure and the workpiece has good stability and bearing capacity.
