The heat insulation layer structure of body of wall and construction method thereof
Technical field
The present invention relates to a kind of heat insulation layer structure of body of wall, and relate to the construction method of this structure, belong to building fitting-out work technical field.
Background technology
Increase at the body of wall of building the energy consumption that insulation layer effectively can reduce air-conditioning, become an Important Action of energy-saving and emission-reduction.And existing insulation layer adopts foam plastic heat-insulating board to belong to loose low density material, different from the coefficient of expansion of concrete wall, adopt the easy creeping deformation of method of stickup, come off, and adopt crab-bolt installation warming plate to be subject to the impact in crab-bolt life-span, lost efficacy crab-bolt corrosion in about 20 years and just need to change, rear current cost is high, cannot accomplish the same life-span with body of wall.
Summary of the invention
The technical problem to be solved in the present invention is, propose a kind of firmly and with the heat insulation layer structure of body of wall with the body of wall in life-span.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of heat insulation layer structure of body of wall, comprise warming plate, body of wall is formed by the concrete of cast in situs, be provided with columnar projections the spaced surface of warming plate, columnar projections offers the concrete through hole can filled by cast in situs, through hole is coated with outrigger reinforcing bar, and outrigger reinforcing bar is that boundary is divided into the first paragraph stretched out to through hole side and the second segment stretched out to through hole opposite side with through hole; First paragraph length much larger than the length of second segment, first paragraph be wrapped in body of wall by the concrete of cast in situs, second segment be wrapped in through hole by the concrete of cast in situs.
Preferably, warming plate is light aggregate concrete heat-insulating plate, accompanies glass fiber reticular cloth in light aggregate concrete.
Preferably, warming plate is filled with foam insulation between adjacent protrusion.
The construction method of the heat insulation layer structure of above-mentioned body of wall comprises the following steps:
(1) at the centre drill through hole of the columnar projections of warming plate;
(2) diameter is less than the outrigger reinforcing bar in the aperture of through hole through through hole, and makes outrigger reinforcing bar all expose termination in the both sides of warming plate;
(3) use the termination of support overlap joint outrigger reinforcing bar, warming plate is fixed on the outboard template position needing cast in situs body of wall;
(4) by cast in situs concrete poured in the cavity surrounded with template inside warming plate, form body of wall and warming plate structure integrally.
(5) remove support after concrete setting, the termination of outrigger reinforcing steel bars exposed in warming plate is cut.
The heat insulation layer structure of body of wall of the present invention adopts the structure of outrigger reinforcing bar, and the beneficial effect had is:
1, fixation between warming plate and body of wall, outrigger reinforcing bar can bear longitudinal shearing and horizontal peeling force.
2, long service life, outrigger reinforcing bar has the application life identical with concrete wall.
3, adopt the method for the pre-installation warming plate when body of wall is built can save the template of body of wall side, and the projection of warming plate is directly engaged, and without the need to bonding agent, simplifies construction, has saved cost with the concrete of body of wall by body of wall.
Accompanying drawing explanation
Be described further below in conjunction with the heat insulation layer structure of accompanying drawing to body of wall of the present invention.
Fig. 1 is the structural representation of the embodiment of the present invention one.
Detailed description of the invention
Embodiment one
The heat insulation layer structure of the body of wall of the present embodiment as shown in Figure 1, comprise the body of wall 3 of warming plate 1 and cast in situs formation, be provided with columnar projections 1-2 the spaced surface of warming plate 1, columnar projections 1-2 offers can the through hole of fill concrete, through hole is coated with outrigger reinforcing bar 2, and outrigger reinforcing bar 2 is that boundary is divided into the first paragraph stretched out to through hole side and the second segment stretched out to through hole opposite side with through hole; First paragraph length much larger than the length of second segment, first paragraph be wrapped in body of wall 3 by the concrete of cast in situs, second segment be wrapped in through hole by the concrete of cast in situs.Warming plate 1 is suppressed by light aggregate concrete and is formed, and accompanies glass fiber reticular cloth 1-1 for strengthening its surface tension, warming plate 1 is filled with foam insulation 1-3 between adjacent protrusion 1-2 in light aggregate concrete.
During construction, following steps are adopted to build the heat insulation layer structure of body of wall of the present invention:
(1) at the centre drill through hole of the columnar projections 1-2 of warming plate 1;
(2) the outrigger reinforcing bar 2 diameter being less than through-hole aperture, through above-mentioned through hole, makes outrigger reinforcing bar 2 all expose termination in the both sides of warming plate;
(3) use the termination of support overlap joint outrigger reinforcing bar, warming plate 1 is fixed on the outside of the body of wall 3 needing cast in situs;
(4) by cast in situs concrete poured in the cavity surrounded with template inside warming plate 1, form the structure of body of wall 3 and warming plate 1 one;
(5) remove support after concrete setting, the termination that outrigger reinforcing bar 2 exposes to warming plate 1 is cut.
The foregoing is only preferred embodiment of the present invention, as long as adopt technical scheme of the present invention, or the amendment made based on conventional means on it of those skilled in the art or equivalent variations, all drop in the protection domain of application claims.
