A kind of curtain wall system of simple and easy installation
Technical field
The utility model relates to building trade, more particularly, relates to the curtain wall system that is installed on the external wall.
Background technology
The curtain wall of prior art is according to the difference of installation form, mainly be divided into frame curtain wall and unit type curtain wall: as shown in Figure 1, frame curtain wall needs first after major structure of construction is installed vertical keel 11 and lateral keel 12, panel 3 is fixed on the panel convergence part 13 of vertical keel 11 installed surfaces with screw again, because need to install at building-site, so installation accuracy requires high, installation period is long; As shown in Figure 2, unit type curtain wall adopts in factory vertical keel 11, lateral keel 12 is connected to each other the formation framework, again panel 3 is mounted on the panel convergence part 13 of vertical keel 11 installed surfaces and forms curtain wall unit, afterwards curtain wall unit is transported to the building site, directly carrying out amalgamation on major structure of construction installs, but the vertical keel 11 between adjacent curtain wall unit needs mutually to peg graft and seal by the weather strip 2 that is arranged in the grafting slit, for satisfying the requirement of pegging graft fully, assembly precision requires high, and owing to need between the phase curtain wall unit to peg graft, cause curtain wall unit to install in order.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of curtain wall system easily assembled, easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of plate curtain wall system of simple and easy installation, comprise splicing and be fixed on a plurality of curtain wall units on the major structure of construction, splicing seams sealant sealing between the adjacent curtain wall unit, described curtain wall unit comprises keel frame and the panel that is installed on the keel frame, and the keel frame of adjacent curtain wall unit is not pegged graft mutually.
Preferably, described keel frame comprises vertical keel and the lateral keel that is mutually permanently connected, and the installed surface of described vertical keel is provided with the panel convergence part that is connected with described panel.
Preferably, described vertical keel adopts the channel-section steel in the gap of opening between curtain wall unit.
Or described vertical keel adopts aluminium extruded sections.
Preferably, the edge of described panel is provided with the section that bends inwards that is connected with described panel convergence part.
Preferably, the section that bends inwards of described panel is fixedly connected with the panel convergence part of described vertical keel by screw.
Preferably, described vertical keel and lateral keel are by being welded to connect into keel frame, and described panel convergence part is the vertical corner fittings that is welded on described keel frame installed surface.
Preferably, the splicing seams of described adjacent curtain wall unit was filled in first the foam rods for the supporting fluid sealant before using sealant sealing.
Preferably, described panel is aluminium sheet.
Unit type curtain wall of the present utility model has following useful technique effect: 1. curtain wall unit is processed, is assembled in factory, and product quality is high; 2. curtain wall unit is transported to on-the-spot integral installation, has saved the time of splicing skeleton and installation panel; 3. mutually do not peg graft between curtain wall unit, cellular installation can not affected by erection sequence, and the scope of operation is wider.
Description of drawings
Fig. 1 is the horizontal profile schematic diagram of prior art frame curtain wall;
Fig. 2 is the horizontal profile schematic diagram of prior art unit type curtain wall;
Fig. 3 is the horizontal profile schematic diagram of the unit type curtain wall of the simple and easy installation of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
See also Fig. 3, unit type curtain wall of the present utility model comprises the curtain wall unit that is comprised of vertical keel 11, lateral keel 12 and panel 3.Wherein vertical keel 11 and lateral keel 12 are preferentially selected the steel material, and described panel 3 is preferentially selected aluminium sheet; Vertical keel described in the curtain wall unit 11 is welded to each other with described lateral keel 12 and forms keel frame 1.Preferably, described keel frame 1 is rectangular frame.More excellent, under the prerequisite of the intensity that guarantees vertical keel 11, for saving material, described vertical keel 11 adopts the channel-section steel in the gap of opening between curtain wall unit.Understandable, described lateral keel 12 can also select other connected mode connection to be connected with vertical keel 11.
The installed surface of described vertical keel 11 also is welded with the panel convergence part 13 of metal material, and this panel convergence part 13 is vertical corner fittings, and vertically stretch out panel convergence part 13; The edge of described panel 3 is provided with the section that bends inwards 31 that is connected with described panel convergence part 13, and the section that bends inwards 31 of described panel 3 is fixedly connected with the panel convergence part 13 of described vertical keel 11 by screw.Understandable, this panel convergence part 13 can also select other can realize vertically stretching out the structure of installing for panel 3 from the installed surface of described vertical keel 11, and this outer panels 3 also can use other mounting method to be mounted to described panel convergence part 13.
The production of above-mentioned curtain wall unit and assembling are all finished in factory.
During installation, described curtain wall unit is transported to the building site, and mutually not plug be installed on the major structure of construction, panel 3 amalgamations of described curtain wall unit form the curtain wall metope, the piece between the described panel 3 is with sealing 4 sealings.Described sealing 4 comprises foam rods 41 and fluid sealant 42, and described foam rods 41 is installed in the piece and seals for supporting described fluid sealant 42, and described fluid sealant 42 is smeared the described piece of covering fully and sealed.
Understandable, keel frame 1 and panel 3 in the utility model can also be selected other materials.
Unit type curtain wall of the present utility model has following useful technique effect: 1. curtain wall unit is processed, is assembled in factory, and product quality is high; 2. curtain wall unit is transported to on-the-spot integral installation, has saved the time of splicing skeleton and installation panel; 3. mutually do not peg graft between curtain wall unit, cellular installation can not affected by erection sequence, and the scope of operation is wider.
Above-described embodiment is the utility model preferred embodiment, and all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection domain.
