Fireproof door capable of being opened automatically

The invention belongs to the field of doors and windows of fixed construction, and particularly discloses a fireproof door capable of being opened automatically. The fireproof door capable of being opened automatically comprises a door frame and a door body. A plurality of first grooves are formed in the two ends of the door frame. A plurality of second grooves corresponding to the first grooves are formed in a wall. The two sides of each second groove are each provided with a third groove. The bottom end of each second groove is provided with an electromagnet connected with a power supply. The end, away from the electromagnet, of each second groove is in sliding connection with a magnetic block with the same magnetic poles as the electromagnet. The two ends of each magnetic block are in static connection with connection plates. One side of each connection plate is connected with a spring, and the springs are fixed in the third grooves. The two ends of the bottom of the door frame are each provided with a track. The indoor end of each track is fixedly provided with an air cylinder, and substances which generate gas when being heated are contained in the air cylinders. According to the technical scheme, when a fire happens, the door frame is automatically separated from the wall and pushed over, and therefore people can still escape for self rescue under the situation that neither the door body nor an escape pipe can be opened.

Structure and construction method of aluminum alloy window

The invention discloses a structure and a construction method of an aluminum alloy window. A door and window structure is characterized in that a circle of steel frame is additionally arranged between the aluminum alloy window and a window opening wall body; polyurethane foam caulking agents are filled between an aluminum alloy frame and the steel frame and between the steel frame and the window opening wall body; heat insulation mortar is respectively smeared on inner and outer walls of the window opening wall body; and facing bricks are pasted on the heat insulation mortar of the outer wall of the window opening wall body. The heat insulation energy saving is combined with the anti-seepage processing, so the cold and hot bridge effect at the window and door edges can be reduced, and the problem of leakage at the door and window edges is also solved. In addition, important significance is realized on the energy saving and the building appearance and use function improvement. The structure and the construction method have the advantages that the process is simple; the construction is convenient; large-scale mechanical equipment is not needed; the energy-saving and anti-seepage effects are good; and the repair quantity of the door and window in the use process can be reduced. The structure and the construction method are applicable to the construction of various kinds of building door and window engineering.

External window construction technology for assembling external window steel subframe by plastic-steel connection corner

InactiveCN101936111AReduce conflictControl the common problems of easy deformationCorner/edge jointsFrame fasteningSealantGalvanization
The invention relates to an installation method of external windows and doors of buildings, in particular to an external window construction technology for assembling an external window steel subframe by plastic-steel connection corner. The construction technology comprises the following steps: actually measuring a structural opening to determine the finish size of a subframe material; and then respectively processing the external window steel subframe, the plastic-steel connection corner and an external window master-frame; by adopting the mode of splicing the plastic-steel connection corner and subframe galvanized square steel to install the steel subframe; after assembling and aligning four corners, installing the steel subframe on the structural opening, wherein the four sides of the subframe are fixed through bolts, and the foaming on the four corners is temporarily fixed; and connecting the external window master-frame with the steel subframe by a screw fastening mode after binding off, foaming and plugging the gaps between the external master-frame and the steel subframe by a sealant, and installing glass after installing the master-frame. In the invention, the subframe is installed in advance, and the master-frame and glass are processed without influencing civil engineering construction, thus reliving the conflict between civil engineering binding-off and door and window installation; and meanwhile, the steel subframe assembling is realized by the connection of plastic-steel connection corner, thus simplifying the installation working processes, reducing the material loss and improving the installation efficiency.

Wall window construction method

The invention discloses a wall window construction method. A spigot is painted on a window opening firstly, wherein the balancing thickness of the spigot is about 15mm; a uniform and regular clearance cavity is formed among a small surface of the spigot, a plastering forming surface of a window frame and the window opening; materials behind the window frame and sealants can be packed sufficiently, evenly and densely and be bonded sufficiently and firmly with a base surface which is painted in advance; good air tightness and water tightness are guaranteed, and the waterproof and heat-preserving using effect is also guaranteed. By means of the wall window construction method, an external window can be installed in place at one time, so that the installation speed of the window is greatly increased; the packing materials are filled in the uniform and regular clearance cavity, so that the amount of foaming agents and the sealants for use is also reduced; the window opening check process is optimized, the installation of the window saves time, labor and materials, and the probability that the window is subjected to secondary pollution is greatly lowered; the problem of leakage around the window is solved fundamentally, the waterproof effect is good, the cost is low, maintenance responsibilities are clear, and the maintenance is convenient.
