Abstract
The utility model relates to an opening keel which comprises a web and wing plates which are formed through continuous hot dipping and cold bend of steel plates, wherein the web is provided with elongated holes which are staggered. Through applying the opening keel the heat bridge effect of the keel is reduced, the heat insulation performance of a wall is increased, the thickness of the wall is thinned, the economic performance is improved, and the application range of light-gauge steel keel outer wall is enlarged.
Description
Technical field
The utility model relates to the employed lightgage steel joist of building light-weight body of wall.
Background technology
The employed lightgage steel joist of lightweight body of wall is to be that the color painted steel strip (band) of base material is made raw material with continuous hot galvanizing steel plate (band) or with continuous hot galvanizing steel plate (band), the light-gauge steel section that adopts cold bending process to produce.
The heat bridge effect of lightgage steel joist is bigger to the thermal property generation harmful effect of exterior wall in the lightweight body of wall.Common lightgage steel joist exterior wall generally only is applied in gentle area and hot summer and warm winter region.Be used for other areas and will strengthen wall thickness, economy is relatively poor.
Summary of the invention
The utility model will solve the strong shortcoming of heat bridge effect of existing body of wall keel, and a kind of body of wall keel that weaken the heat bridge effect are provided.
Perforate keel described in the utility model comprise web and wing plate to form behind the continuous hot galvanizing steel plate cold bending, have staggered slotted hole on the described web.
Further, described slotted hole is many row's shapes, staggers mutually in the end of adjacent row's slotted hole.
Further again, described keel are U type keel.
Perhaps, described keel are C type keel.
After keel of the present utility model were used in exterior wall, carried out the end that the paired heat conducting blocking-up of the long hole shape of being opened, conduction of heat must the pile warp slotted holes, because adjacent slotted hole is staggered, heat conducting path is artificially prolonged, and heat conducting cross section connects and reduced greatly.The heat-insulating property of body of wall can be improved 20～30%.
The utility model has the advantages that: reduced the heat bridge effect of keel, improved wall insulation performance, can reduce wall thickness, improved economy, enlarged the range of application of lightgage steel joist exterior wall.

Fig. 2 is the schematic diagram that the utility model is used as U type keel.
Fig. 3 is the schematic diagram that the utility model is used as C type keel.
The specific embodiment
Embodiment one
With reference to Fig. 1, Fig. 2, perforate keel described in the utility model comprise web 1 and wing plate 3 to form behind the continuous hot galvanizing steel plate cold bending, have staggered slotted hole 2 on the described web 1.
Described slotted hole 2 is many row's shapes, staggers mutually in the end of adjacent row's slotted hole 2.
The keel that present embodiment adopts are U type keel.
After keel of the present utility model are used in exterior wall, the slotted hole of being opened 2 forms heat conducting blocking-up, conduction of heat must pile warp slotted hole 2 the end carry out, because adjacent slotted hole 2 is staggered, heat conducting path is artificially prolonged, and heat conducting cross section connects and reduced greatly. the heat-insulating property of body of wall can be improved 20～30%.
Embodiment two
With reference to Fig. 1, Fig. 3, the difference of present embodiment and embodiment one is that the keel that adopted are C type keel.All the other structures are identical.
The described content of this manual embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
Claims (4)
1. the perforate keel comprise web and wing plate to form behind the continuous hot galvanizing steel plate cold bending, it is characterized in that: have staggered slotted hole on the described web.
2. perforate keel according to claim 1 is characterized in that: described slotted hole is many row's shapes, staggers mutually in the end of adjacent row's slotted hole.
