The invention has the advantages of good wall integrity, convenient construction, no need for formwork removal, low average density and good thermal insulation performance. Moreover, for the wall body constructed in the method, the manufacturing cost per unit area can be reduced.

The invention discloses a process for replacing hoisting ropes, which comprises the steps of: 1, arranging new and old rope hoists at an upper wellhead, and lifting a second cage to the upper wellhead; 2, lowering the second cage, and arranging a pair of long boards on an old rope on the same side of the second cage at intervals of 50 meters; 3, separating the old rope from a first cage and connecting the old rope with an old rope take-up hoist; 4, when the second cage is lifted to the upper wellhead, taking up the old rope by the old rope take-up hoist, dismounting the long boards in the step 2, and breaking the old rope; 5, connecting the rope end of a new rope with an upper breaking point, and connecting a second end of the old rope with a lower breaking point; 6, driving the new rope by the old rope to wind two hoisting sheaves and a winch sequentially, breaking the new rope and the upper breaking point, and connecting the new rope with the second cage; and 7, driving the new ropeto descend by the second cage, applying pull force to the new rope at intervals of 50 meters, arranging the long boards on the new rope and a to-be-replaced old rope, removing the pull force, breaking the new rope, and connecting the new rope with the first cage.

The invention provides a fastener plug-in type curved surface metal roof which comprises a base frame, primary purline supporting components, lengthening connecting fasteners, primary purlines, primary and secondary purline through connection components, secondary purlines, secondary purline panel through connection components, roof panel components and sealing components. The base frame is fixedly mounted on a civil engineering foundation roof face. The primary purlines are fixedly connected with the base frame through the primary purline supporting components. The secondary purlines are connected with the primary purlines through the primary and secondary purline through connection components. The secondary purline panel through connection components are connected with the secondary purlines. The roof panel components are connected with the secondary purline panel through connection components, two adjacent roof panel components are connected in an inserting mode, and the sealing components are arranged in the clearances of the roof panel components. A construction method mainly comprises the step that the base frame, the primary purline supporting components, the primary purlines, the primary and secondary purline through connection components, the secondary purlines, the secondary purline panel through connection components, the roof panel components and the sealing components are mounted in sequence. According to the fastener plug-in type curved surface metal roof and the construction method, steel and manpower cost can be effectively saved, the construction period can be shortened, and the new construction method of the curved surface metal roof is provided.

The invention discloses an assembling integrated type window frame for a steel structure, and a construction method of the assembling integrated type window frame. The construction method comprises the following steps: producing components of the assembling integrated type window frame in a factory in advance and in batches; setting a clamping groove in the outer side of each component; conveying the components to an industrial or civil building construction site of the steel structure which is manufactured; and taking a hole of each steel grid consisting of vertical H-shaped steel and transverse H-shaped steel of a wall structure of the steel structure as a position where the building needs to open a window, buckling the clamping groove of each component on the H-shaped steel forming the hole, and pouring fine aggregate concrete into the clamping grooves of upper window frame and lower window frame components of the assembling integrated type window frame, so that the assembling integrated type window frame and the steel grid H-shaped steel of the steel structure can be connected into a whole, and construction of the assembling integrated type window frame for the steel structure is finished. The assembling integrated type window frame for the steel structure, and the construction method of the assembling integrated type window frame have the advantages of low manufacturing cost, easiness in manufacturing and construction, high production efficiency, high quality, long service life, high fireproof performance, avoidance of environmental pollution and the like.

The invention provides a color base paint for woodware, which comprises components and the weight content of each component are: 50%-75% of alkyd resin, 5%-20% of filler, 15%-30% of solvent, covering Flavoring agent 0.1%-1%%, auxiliary agent 0.1%-1%. The coloring base paint for woodware provided by the invention can be combined with color essence to produce woodware paints of various colors, and can be directly rubbed on the primer or topcoat of woodware. The construction is simple, the coloring is uniform, and natural leveling is achieved. Low odor and low VOC meet the requirements of environmental protection, so that after the wood is painted, it can achieve a decorative effect of bright and rich colors and clear textures.

The invention provides an integrated ward. The integrated ward comprises a sickbed and a partition wall, wherein the partition wall on at least one side comprises an inner wall and an outer wall; an accommodating space is formed between the inner wall and the outer wall; a medical gas valve box, a strong current box, a weak current box and an isolating transformer are arranged in the accommodating space; one end of the medical gas valve box is connected to a medical gas terminal inside the integrated ward, and the other end of the medical gas valve box is connected with a medical gas source pipeline outside the integrated ward; the strong current box is connected with an external power supply and used for supplying power to electrical equipment in the ward; a plurality of internal weak current equipment interfaces are formed in one end of the weak current box and connected to the interior of the integrated ward; a plurality of external weak current equipment interfaces are formed in the other end of the weak current box and used for connecting external lines; the isolating transformer is used for preventing electric leakage or voltage instability.
