Abstract

This invention discloses a kind of fixed device of the outer wall facing form board of the building industry, it is a bridge-cut-off setting-up fastening external member of the heat preservation polyurethane pouring system outside the outer wall. In order to improve the heat preservation effect of the outer wall, it is going to fix a facing form board in the surface of the wall, pouring the polyurethane which is liquid before being solidified between the surface of the wall and the facing form board, this invention provides fastening external member of the facing form board. The fastening external member includes the bottom external member and interconnecting external member, one end of them is fixed on the wall the other end id connected with the facing form board, the bottom-end flute, it can adjust the space between the facing form board and the surface of the wall, to ensure that every facing form board after construction are in the same level, and ensure the heat preservation required polyurethane thickness is in the prescribed limit.

Description

External wall outer insulation polyurethane hard foam filling system bridge cut-off roll adjustment fastening kit

One, technical field

The invention belongs to the fastening devices of building trade exterior wall body piercing panel.

Two, background technology

China's building energy conservation level is far below developed country, and the unit area building energy consumption is equivalent to two or three times of the close developed country of weather conditions in the world.To continue the bigger building construction scale of maintenance in 15 years from now on China, and on the basis that existing 50% energy conservation standard requires, set up and implement 65% higher standard, the development of propelling low energy consumption, super low energy consumption and green building.Held hard polyurethane foams in Beijing in the recent period and applied seminar, determined that its promotion prospect also pointed out the problem that will solve in building energy saving field.The support fixation problem of polyurethane hard foam filling mould for example.Specifically, install one deck polyurethane foam additional, to improve the wall thermal insulating effect at the outer exterior surface of wall of building.The polyurethane that is in a liquid state before solidifying to be poured in surface of wall, at surface of wall part fixing one deck facing plate also, make facing plate and body of wall that 3-6 centimetre of gap be arranged, filling polyurethane in the gap, the polyurethane after the curing play bonding facing plate and wall thermal insulating.So, the installing and fixing of wall facing plate before the polyurethane perfusion is exactly the problem that at first will solve.

Three, summary of the invention

In order to address the above problem, the present invention has designed external wall outer insulation polyurethane hard foam filling system bridge cut-off roll adjustment fastening kit.Its technical scheme is: fastening kit comprises bottom external member and intermediate connecting sleeve spare, strip body of wall fixture in the external member of bottom is horizontally fixed on the body of wall bottom, template support is connected with the body of wall fixture by bolt, has one to be slotted hole in the connection screw of two parts.Strip body of wall fixed head in the intermediate connecting sleeve spare is horizontally fixed on the body of wall and its corresponding template of placing presses support member to link together by screw and bridge cut-off sleeve pipe and body of wall fixed head.Adopt this securing member before filling polyurethane, to be fixed on the facing plate of exterior wall surface on the body of wall, become the template of filling polyurethane, be bonded in securely on the body of wall behind the filling polyurethane, position to the distance of surface of wall that securing member and template link can be adjusted, and guarantees that the surface of wall after the construction is in the same plane.So just polyurethane is successfully realized as the target that heat insulating energy saving material is applied in the energy-saving building technology.

Five, the specific embodiment

Below in conjunction with accompanying drawing embodiments of the present invention are further elaborated.Reform architectural construction technology, promote energy-saving building technology, comprising utilizing hard polyurethane foams to reach energy-conservation purpose as building thermal insulation material.This technology is applied in building energy saving field at hard polyurethane foams of holding in Beijing not long ago and is obtained in the seminar certainly.A kind of implementation method wherein is at the additional one deck polyurethane material of the exterior wall external surface of building, if the liquid state of polyurethane before curing poured into, must seal its reperfusion space.So fixing one deck exterior wall finish lamina membranacea outside body of wall.。External wall outer insulation polyurethane hard foam filling system bridge cut-off roll adjustment fastening kit promptly is the facility that is used for fixing the exterior wall finish template.The fixing of exterior wall finish template should satisfy two conditions: the one, according to the heat-retaining condition in different latitude area, require layer of polyurethane thickness difference; Be uneven unavoidably after the completion of same metope, phase difference centimetre sometimes, and the exterior wall finish template should guarantee in one plane, this just requires fastening kit can regulate the spacing of the local relatively body of wall of facing template that it fixes.The 2nd, the facing template be fixed with filling polyurethane after should be connected with body of wall reliably, can not come off, it is attractive in appearance that fastening kit can not be exposed to the outer influence of wall.In addition should be simple to operate, the easy degree of progress speed of constructing.Fastening kit according to above-mentioned requirements design has two kinds of structures, and the one, the bottom external member, as shown in Figure 1, it is the external member of using when beginning to install and fix the most the lower layer of facing plate according to snap the line at the bottom of wall.Comprise body of wall fixture (1) and template support (3), these two elongated elements are converted into "  " shape section with thin plate.Body of wall fixture (1) level and body of wall are fixed, and template support (3) is connected with body of wall fixture (1) by bolt (2).There is one to be slotted hole in two bolts hole, therefore can regulates the distance between two.There is the bending of 2-2.5 millimeter on the vertical edge top of template support (3), so that insert in the groove of following 3 mm wides of facing template, facing template lower end is fixed.

Figure 2 shows that the external member-intermediate connecting sleeve spare of second kind of structure, the body of wall fixed head (4) of its strip is fixed on the body of wall by screw (8) and Plastic expand cork (9), presses support member (7) to be connected with body of wall fixed head (4) with bridge cut-off sleeve pipe (6) by screw (5) with its template staggered relatively.The selection of upper, middle and lower punching convenience screw position.Two screws (5) are separately fixed on part (4) and (7), and one is that one of positive screw thread is anti-screw thread, the distance of rotation bridge cut-off sleeve pipe (6) adjustable features (4) and (7).Template presses the upper and lower limit of support member (7) that the bending of 2-2.5 millimeter is arranged, increasing the steadiness that template is installed, below they insert respectively and in the top facing template groove, play a part under compress upper support.After the facing template was installed, bottom external member and intermediate connecting sleeve spare all were closed stealth, and these fastening kits also need not be dismantled.After polyurethane foam to be poured into was solidified, facing template and fastening kit all were bonded on the body of wall securely, and bridge cut-off sleeve pipe (6) adopts nonmetals to make, and because of its coefficient of thermal conductivity is low, had blocked " heat is transmitted bridge " of exterior sheathing and body of wall.

The template of intermediate connecting sleeve spare presses being connected of support member (7) and body of wall fixed head (4) and the spacing adjustment also can be adopted the single screw structure; At this moment bridge cut-off sleeve pipe (6) should be fixed together with body of wall fixed head (4), presses screw on the support member (7) to be screwed into to back-out with template and adjusts spacing.
