Description
Technical Field
The invention relates to the technical field of building prefabricated panels, in particular to a PC heat-insulation integrated plate and a production method thereof.
Background
Precast Concrete (PC) is generally used to prepare concrete building members, such as external wall panels, floor slabs, stairways, and the like. The design and implementation process of the PC external wall panel member will be described as an example. The existing PC external wall panel component is a structural rabbet with an upper plate and a lower plate which are lapped and a convex outer side and a concave inner side at the lower part, the top of the PC external wall panel component comprises a reserved structural dowel bar with one end integrally cast with a cast-in-place beam and a cast-in-place layer of a laminated slab, namely, a cast-in-place section cast through a cast-in-place formwork is required to be arranged between the upper PC external wall panel component and the lower PC external wall panel component, so that the upper PC external wall panel component and the lower PC external wall panel component are connected.
For the PC external wall panel component, an external wall panel heat insulation structure needs to be arranged, so that the design requirement of external wall heat insulation is met. In the related art, common external wall insulation methods include external wall insulation, internal wall insulation, and sandwich insulation.
Fig. 1A is a sectional view showing an exterior wall insulation in the related art. For the external thermal insulation of the external wall, the actual thermal insulation effect is the best. However, because the PC outer wall construction has an interlayer pouring section, the construction precision of the cast-in-place section and the construction precision of the prefabricated section are different, and the cast-in-place section needs template construction, the integral leveling construction is carried out on the integral outer wall surface after the PC outer wall construction is finished, and then the insulation boards are manually paved and pasted on site. Namely, because the paving operation needs to be carried out on site, the problems of uncontrollable field implementation process, poor weather resistance of the material and poor combination of a heat preservation notebook and a PC outer wall interface (a smoother interface) exist, and the problem that the outer heat preservation board is easy to fall off 3-5 years after the completion of the project is solved.
Fig. 1B is a sectional view showing the internal thermal insulation of an exterior wall in the related art. For the internal thermal insulation of the outer wall, an indoor extension section exists besides the outer wall plate, so that field construction is required. If the indoor surface of the PC external wall panel member has a supporting embedded part (e.g. an integral prefabricated), the difficulty of protecting the finished product will be increased. In addition, in the subsequent process of cutting and supporting the embedded part, the field construction operation is influenced, the repair work is brought, and the overall construction efficiency is reduced. Therefore, the heat preservation in the outer wall can not adopt a prefabrication mode and only can be carried out on-site construction. In addition, the problem of interlayer cold bridge also exists in the internal thermal insulation of the external wall; moreover, the heat insulation in the outer wall greatly reduces the indoor practical use space and simultaneously influences the hanging of articles on the inner wall surface.
FIG. 1C shows a cross-sectional view of a sandwich insulation in the related art. For sandwich insulation, it may be preformed. Because the heated board is for the design of piecemeal formula, in order to fixed heated board, add the page board. However, this approach has a number of problems: the problems of discontinuous heat preservation and cold bridge exist, the external heat preservation effect is influenced, and after the temperature difference exists at the corresponding indoor part, the condensation phenomenon is easily formed, so that the wall surface is mildewed; the added outer leaf plate not only increases the thickness of a single component, but also increases the self weight of the single component; due to the increase of the dead weight, the flexibility of the disassembly of the component is influenced, and the difficulty and the cost of the production and the transportation of the component are increased; in addition, the increase of the self weight of a single component also influences the site for stacking on site, the equipment for hoisting and the management requirements.
At present, an effective solution is not provided aiming at the problems that in the related technology, a heat insulation integrated plate cannot be prefabricated, the site construction is needed, the thickness of the heat insulation integrated plate is thick, the self weight is large, the heat insulation is discontinuous and the like.

For step S202, before installing the anchor element, a placement hole is opened at a predetermined position of the insulation board according to construction requirements or design requirements, and then the anchor element is installed in the placement hole.
The anchor element does not protrude out of the outer end face of the insulation board, namely, the anchor element is embedded into the insulation board under the condition that the anchor element is installed on the insulation board, and the bottom end face of the anchor element and the outer end face of the insulation board are located on the same horizontal plane, namely, are in a flush state.
The purpose of step S202 is to avoid the problem that the outer end face of the insulation board is not in contact with the horizontal plane due to the fact that the anchoring element protrudes out of the outer end face of the insulation board, and to prevent the insulation board from being bent under the action of gravity of concrete in the subsequent prefabrication production process.
In some embodiments, the distance of the anchoring elements protruding out of the inner end face of the insulation board is 6-15 cm.
In addition, for the number of the anchoring elements, 6-8 anchoring elements are arranged on each square meter of the heat insulation board.
In step S204, the inner-blade-side mold is a rigid mold, such as a metal mold, which has a strong pressure-resistant capability, and is not deformed or displaced when concrete is poured into the inner portion of the inner-blade-side mold.
In addition, when the inner blade side die is placed, the position relationship between the edge of the inner blade side die and the edge of the heat insulation plate has the following types:
the edge of the inner blade side mould is not in contact with the edge of the heat insulation plate, namely the projection range of the inner blade side mould is positioned in the projection range of the heat insulation plate from the overlooking view;
(II) the edge of the inner blade side mould is flush with the edge of the heat insulation plate mould, namely, the projection range of the inner blade side mould is positioned inside the projection range of the heat insulation plate when viewed from the top, and one boundary of the projection range of the inner blade side mould is coincided with one boundary of the projection range of the heat insulation plate;
(III) the edges of the two inner blade side molds are flush with the edges of the two heat insulation plates, namely, the projection range of the inner blade side molds is positioned inside the projection range of the heat insulation plates from the overlooking view, and two boundaries of the projection range of the inner blade side molds are superposed with two boundaries of the projection range of the heat insulation plates; (wherein the two inner blade side mold edges may be adjacent or spaced apart)
(IV) the edges of the three inner blade side moulds are flush with the edges of the three heat insulation plates, namely, the projection range of the inner blade side moulds is positioned inside the projection range of the heat insulation plates from the overlooking view, and three boundaries of the projection range of the inner blade side moulds are superposed with three boundaries of the projection range of the heat insulation plates;
and (V) the edges of the four inner blade side molds are flush with the edges of the four heat insulation plates, namely, the projection range of the inner blade side molds is positioned inside the projection range of the heat insulation plates from the overlooking view, and the four boundaries of the projection range of the inner blade side molds coincide with the four boundaries of the projection range of the heat insulation plates.
In the first (first) case, can cut its PC heat preservation intergral template that obtains according to the construction needs for the heated board of PC heat preservation intergral template can only extend in one direction of wallboard, or two directions extend, or three directions extend. This kind of PC keeps warm integrative board can be applicable to the construction conditions of difference to can cut at the production place, or cut at the job site.
In the second (second) to fourth cases, the obtained PC insulation integrated board is a personalized integrated board specially adapted for different building structures, such as exterior wall members, window members, corner members, etc., without secondary cutting.
For the (fifth) case, which is an extreme case, it is only applicable to special building scenarios.
In some embodiments, the distance between at most three insulation board edges of the insulation board and the inner blade side mold edge corresponding to the insulation board edge is 0-600 mm.
In some embodiments, the distance between the edge of the inner blade side mold and the edge of the heat preservation plate can be 0-550 mm, 0-500 mm, 50-550 mm, 50-500 mm, 200-500 mm; or a fixed value, such as 50mm, 125mm, 180mm, 200mm, 350mm, 400mm, 500mm, 550 mm.
Wherein, because the inner blade side mould has a certain thickness, after the inner blade side mould is removed, the distance between at least one heat preservation plate edge of the heat preservation plate and the wallboard edge corresponding to the heat preservation plate edge of the wallboard is 0 to (600+ thickness of the inner blade side mould).
In some embodiments, after the inner blade side mold is removed, the distance between at least one insulation board edge of the insulation board and the corresponding wallboard edge of the insulation board is 0-600 mm, 0-550 mm, 0-500 mm, 50-550 mm, 50-500 mm, 200-500 mm; or a fixed value, such as 50mm, 125mm, 180mm, 200mm, 350mm, 400mm, 500mm, 550 mm.
In some embodiments, before the inner end surface of the insulation board is provided with the inner blade side mold, the insulation splicing plates with smaller sizes are spliced according to construction requirements, so that the insulation board with larger sizes is obtained.
For the heat-insulating plate formed by splicing, the heat-insulating splice plate with larger size needs to be ensured to be positioned at the edge of the heat-insulating plate, and the heat-insulating splice plate with smaller size is positioned in the middle of the heat-insulating plate.
Specifically, for the insulation splice at the edge of the insulation panel, the ratio of its dimension at the outside of the concrete formed wall panel to its dimension at the inside of the concrete formed wall panel is less than 1: 1, i.e., the dimension (e.g., width or length) on the outside of the concrete formed wall panel is less than the dimension (e.g., width or length) on the inside of the concrete formed wall panel.
As shown in fig. 2, the insulation board 1 is composed of a first insulation splice plate a, a second insulation splice plate b and a third insulation splice plate c, wherein the first insulation splice plate a includes a portion with a length of a1 located outside the wall panel 5 and a portion with a length of a2 located inside the wall panel 5, and the second insulation splice plate b includes a portion with a length of b1 located outside the wall panel 5 and a portion with a length of b2 located inside the wall panel 5. Wherein a1/a2 is less than 1, and b1/b2 is less than 1.
In addition, the heat-insulating splicing plate can be a single plate without other components, and can also be a heat-insulating splicing plate provided with an anchoring element.
Specifically, the installation of the anchoring element can be carried out after the heat-insulation splicing plates are spliced into the heat-insulation plate; or the heat-preservation splice plates can be spliced after the anchor elements are installed on the heat-preservation splice plates.
In some embodiments, after the heat-insulating splicing plates are spliced to form the heat-insulating plate, a first plugging element needs to be filled between the splicing seams of two adjacent heat-insulating splicing plates, so that the problem of slurry leakage in the pouring process is avoided.
Wherein, the first plugging element is a sticking substance, such as an adhesive tape.
For step S208, before pouring concrete into the pouring space, a second plugging element needs to be filled at a joint between the inner blade plate side mold and the insulation board, so as to avoid slurry leakage during the pouring process.
Wherein, the second shutoff element is the shutoff adhesive tape. Specifically, the joint of the inner blade plate side mold and the heat insulation plate is subjected to sealing and gluing treatment, so that side seams are sealed.
In some embodiments, before step S202, the method further includes:
and S200, placing the insulation board on a horizontal plane, and enabling the outer end face of the insulation board to be in contact with the horizontal plane.
Specifically, one surface with good flatness is used as the outer end surface of the heat insulation plate and is placed downwards to be in contact with a horizontal plane; the flatness difference is prevented from being used as the inner end face of the heat insulation plate and is arranged upwards, so that the flatness difference is used as a joint face with concrete.
In addition, in concrete prefabricated production process, the horizontal plane is steel platform's horizontal plane, and its surface is smooth, can not cause the damage to the outer terminal surface of heated board.
In the present invention, the insulation board is used as a prefabricated template of a PC insulation integrated board, and it needs to have the following parameters: the dry density of the insulation board is 160-220 kg/m3The compression strength is more than or equal to 0.30mPa, the vertical and plate surface tensile strength is more than or equal to 0.25MPa, the compression elastic modulus is more than or equal to 20000kPa, the bending load is more than or equal to 3000N, the bending deformation is more than or equal to 6mm, the volume water absorption is less than or equal to 6%, the heat conductivity coefficient is less than or equal to 0.054W/m.K, the softening coefficient is more than or equal to 0.8, the drying shrinkage is less than or equal to 0.3%, and the combustion.
In some embodiments, the impact resistance of the insulation board is greater than or equal to 10 times.
Specifically, in the production process, the heated board is as the bottom mould, and it needs to bear the dead weight of the concrete that is located its top to under the effect of concrete dead weight, the circumstances such as serious deformation can not appear.
In the related art, the compression strength of the heat insulation plate is not enough to enable the heat insulation plate to be used as a bottom formwork and only can be used as a vertical outer formwork on a construction site.
