Part end and keel are overall, and right angle hook Transducers Embedded in Concrete plate 21 when concrete slab 211 is poured treats that concrete slab 21 has been conserved
Cheng Hou, hook and concrete layer are combined, with bonding strength.With this, the two is reliably connected by hook 22b.
Punching hook 22b width is 8mm to 15mm, and hook length is the 1/2 of concrete layer thickness, hook flange length
8mm to 15mm.Hook quantity is 200mm to 300mm according to different wall performance requirements, spacing.
The third：Y type connectors.
As shown in Figure 11 to Figure 15, lightgage steel joist framework 23 and concrete slab 21 can be connected using Y type connectors 22c
Connect.Y type connectors 22c is made using punching press and bending technique.Logical of Y type connector 22c roots self threading pin and light steel dragon
Bone 23 is connected, head Transducers Embedded in Concrete layer, connects concrete slab 21.
Y type connector 22c thickness is 1.5mm to 2.5mm, and length can be elongated along keel direction, can also be interrupted.
4th kind：Keel crimping with holes.
As shown in Figure 16 to 19, by bending and Sheet Metal Forming Technology, a kind of special special-shaped c-type with crimping with holes is made
Keel 231a.The c-type keel side side plate bending is into crimping 22d, while crimping web holes, crimping Transducers Embedded in Concrete plate, shape
Into connection.
Lightgage steel joist composite concrete wallboard template is divided：
Lightgage steel joist composite concrete wallboard can realize different alien invasion decorative effects, including traditional exterior coating decorations
Face, clear-water concrete effect, instead play one-shot forming patch block or stone effect, moulding concrete effect etc..
As shown in Figure 20, Figure 21 and Figure 22, designed according to different elevations of building, lightgage steel joist composite concrete wallboard exists
Template divide be can be divided into horizontal stripe plate 2a between window, band window it is many between horizontal stripe plate 2b, band window it is many between vertical bar plate 2c and vertical bar plate（Bao Zhu
Plate）2d.
Lightgage steel joist composite concrete wallboard Breadth Maximum is 4 meters, and maximum length is 16 meters.Can be pre- in wall processing and fabricating
Window opening and door opening are stayed, maximum dimension of opening is 3 meters.After wall completes, door and window can be installed, can also be installed when wall
To after building main structure, then door and window is installed.
Lightgage steel joist composite concrete wallboard joints waterproofing design：
Between lightgage steel joist composite concrete wall panels, generally be configured with 15mm-30mm expansion joint, wall seam it is close
Waterproof is sealed, the waterproof sealing system 4 that can be developed using inventor.The waterproof system has the function of infiltration discharge and monitoring.
As shown in figure 23, waterproof system 4 is by inside and outside twice waterproof layer（41、43）Constituted with middle aquitard 42.
Back lining materials 411 in inner side waterproof layer 41 is included most（Such as polyethylene rod）With fluid sealant 412（Including silicone-based
Row, modified silicone series and Polyurethane fluid sealant）；Outside waterproof layer 43 is made up of back of the body fluid sealant 431.
Waterproof layer on the outside of inside（41、43）Between, it is middle aquitard 42.Filling reticulated foam or sponge etc. pair in the layer
Water has the material of interim adsorption function, can simultaneously serve as the back lining materials of outside waterproof gasket cement 431.
, can be in middle aquitard mounting design drainpipe 44 between building is per layer 2-3.The side of drainpipe 44 is sealed
Glue blocks to form fluid sealant dam 45.
Aquitard working mechanism and effect：
1st, circulation air.Because the material of aquitard 42 is foamed material, air can pass through drainpipe 44 and extraneous recycle stream
It is logical, it is ensured that the rapid draing after infiltration, play a part of moistureproof and mildewproof, while can also lower infiltration blast.
2nd, infiltration detection.Once external wall system somewhere outermost waterproof layer fails, rainwater penetrates into aquitard 42.Aquitard 42
Reticulated foam, which short can be cached, absorbs moisture, while being also the passage of moisture discharge.Weather stops after raining, and retains in aquitard
Moisture can gradually be discharged by drainpipe 44, and exterior wall can form water droplet or water stain 442 at drain pipe port 441.It can determine whether accordingly
The outermost waterproof layer 43 of the upper area of drain pipe port 441 is failed, and maintenance and repair can be carried out in time（Such as replace fluid sealant）.This
Sample can just form a kind of monitoring and maintenance mechanism in real time, prevent the further seepage of rainwater, destruction wall body structure and interior decoration,
Postpone the service life of wall.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
