Description

Technical Field

[0001] This utility model relates to the field of exterior wall tiling technology, specifically to a passive building exterior wall with staggered tiling. Background Technology

[0002] During the construction of passive building insulation systems, due to the large density of rock wool boards, the insulation layer thickness of passive buildings is much greater than that of ordinary buildings. This leads to more stringent requirements for the installation of insulation board brackets, often necessitating the installation of insulation board brackets on each natural floor of the building.

[0003] Currently, the commonly used PVC brackets on the market support both the inner and outer layers of rock wool insulation boards. However, a through gap appears between the inner and outer rock wool boards at the height of the bracket, which fails to effectively block the thermal bridging effect. Moreover, the PVC brackets deform severely and cannot fully support the rock wool boards, causing the rock wool boards to shift downwards. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a staggered passive building exterior wall. Because the inner and outer insulation board brackets in this staggered passive building exterior wall are staggered by a certain height difference, after the insulation boards are laid, the gaps between all the inner and outer insulation boards are staggered, avoiding the phenomenon of through-seams and effectively blocking the thermal bridging effect. The connecting piece further strengthens the connection between adjacent outer insulation board brackets, which can suppress the deformation of the outer insulation board brackets and thus prevent the insulation boards from shifting downward.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A staggered passive building exterior wall includes an inner insulation board bracket fixed to the wall surface, with an outer insulation board bracket fixedly installed on the inner insulation board bracket; each inner insulation board bracket simultaneously holds two symmetrical inner insulation boards on the left and right sides, and the outer insulation board bracket holds an outer insulation board located between the two inner insulation boards, so that the vertical gaps of all inner and outer insulation boards are staggered; there is a certain height difference between the horizontal support plate in the inner insulation board bracket and the lower horizontal support plate in the outer insulation board bracket, so that the horizontal gaps of all inner and outer insulation boards are staggered; a connecting piece for supporting the outer insulation board is fixedly installed between each pair of adjacent outer insulation board brackets.

[0007] By adopting the above scheme, since the inner and outer insulation board brackets in the staggered passive building exterior wall are staggered by a certain height difference, after the insulation boards are laid, the gaps between all inner and outer insulation boards are interlaced, avoiding the phenomenon of through-seam and effectively blocking the thermal bridging effect. The connecting piece further strengthens the connection between adjacent outer insulation board brackets, which can suppress the deformation of the outer insulation board brackets and thus prevent the insulation boards from shifting downward.

[0008] As a preferred implementation method for staggered passive building exterior walls, the inner insulation board bracket is formed by L-shaped sheet metal stamping; the outer insulation board bracket is formed by Z-shaped sheet metal stamping; and the connecting piece is formed by I-shaped sheet metal stamping.

[0009] By adopting the above solution, in order to improve the rigidity and strength of the inner insulation board bracket, the outer insulation board bracket, and the connecting piece, all three are integrally stamped into sheet metal using a mold, which facilitates mass production and improves the quality of use.

[0010] As a preferred implementation method for staggered passive building exterior walls, the inner insulation board bracket has internally welded and fixed reinforcing ribs that divide the left and right sides equally.

[0011] In order to facilitate the simultaneous placement of two symmetrical inner insulation boards on the inner insulation board bracket, the two inner insulation boards are separated by welding reinforcing ribs. At the same time, these reinforcing ribs further enhance the load-bearing strength of the inner insulation board bracket.

[0012] As a preferred embodiment of passive building exterior wall with staggered cladding, insertable angle steel is welded and fixed on both sides of the spacer reinforcement rib. There is a wedge-shaped groove between the insertable angle steel and the transverse support plate of the inner insulation board bracket. The spacing of the wedge-shaped groove gradually decreases from the outside of the inner insulation board bracket to the inside. A slot is provided in the middle of the upper transverse support plate of the outer insulation board bracket. The slot can be matched with the spacer reinforcement rib for limiting.

[0013] By adopting the above scheme, in order to achieve automatic locking of the outer insulation board bracket during installation, when the slot and the spacer reinforcing rib are matched for limiting, the spacing of the wedge grooves gradually decreases from the outside to the inside of the inner insulation board bracket. When the outer insulation board bracket is struck with a hammer, the upper horizontal support plate of the outer insulation board bracket is continuously clamped by the inserted angle steel, thereby achieving automatic locking of the outer insulation board bracket during installation.

[0014] As a preferred embodiment of passive building exterior wall with staggered joint cladding, the vertical support plate of the inner insulation board bracket has round holes on both sides of the spacer ribs, and the inner insulation board bracket is fixed to the wall surface by installing expansion screws into the round holes.

[0015] Using the above solution, in order to fix the inner insulation board bracket, expansion screws can be installed in the round holes to quickly fix it.

[0016] As a preferred implementation method for staggered passive building exterior walls, the length of the vertical support plate of the outer insulation board bracket is 150-250mm.

[0017] In order to achieve the vertical misalignment of the outer insulation board and the inner insulation board by adopting the above scheme, the length of the vertical support plate of the outer insulation board bracket is designed to be 150-250mm, which can effectively stagger the gap between the outer insulation board and the inner insulation board.

[0018] As a preferred implementation method for staggered passive building exterior walls, multiple evenly distributed triangular reinforcing ribs are welded and fixed between the lower horizontal support plate and the vertical support plate of the outer insulation board bracket.

[0019] In order to improve the strength of the outer insulation board bracket, triangular reinforcing ribs are welded to the above solution to prevent deformation of the outer insulation board bracket.

[0020] As a preferred embodiment of passive building exterior wall with staggered joint cladding, both ends of the lower horizontal support plate of the outer insulation board bracket are provided with elongated oval holes one, and both ends of the connecting piece are provided with elongated oval holes two; the outer insulation board bracket and the connecting piece are fixed together by installing rivets in the elongated oval holes one and two.

[0021] Using the above solution, in order to fix the outer insulation board bracket and the connecting piece, rivets can be installed in the first and second oblong holes to quickly fix the two.

[0022] As a preferred embodiment of staggered passive building exterior wall installation, the dimensions of the inner insulation board bracket satisfy L1=T1; where L1 is the width of the transverse support plate of the inner insulation board bracket and T1 is the thickness of the inner insulation board; the dimensions of the outer insulation board bracket satisfy T2 / 2<L2<T2; where L2 is the width of the lower transverse support plate of the outer insulation board bracket and T2 is the thickness of the outer insulation board.

[0023] In order to meet the construction requirements, the dimensions of the inner insulation board bracket must satisfy L1=T1, so that the inner insulation board and the outer insulation board will be in contact with each other; the dimensions of the outer insulation board bracket must satisfy T2 / 2<L2<T2, so that the outer insulation board bracket will be hidden in the gap, which is not only more aesthetically pleasing, but also saves materials.

[0024] After adopting the above technical solution, the beneficial effects of this utility model are:

[0025] 1. Because the inner and outer insulation board brackets in this staggered passive building exterior wall installation are offset by a certain height difference, after the insulation boards are installed, the gaps between all inner and outer insulation boards are staggered, avoiding the phenomenon of through-seams and effectively blocking the thermal bridging effect; the connecting piece further strengthens the connection between adjacent outer insulation board brackets, which can inhibit the deformation of the outer insulation board brackets and thus prevent the insulation boards from shifting downwards;

[0026] 2. In order to improve the rigidity and strength of the inner insulation board bracket, the outer insulation board bracket and the connecting piece, all three are integrally stamped into sheet metal using a mold, which facilitates mass production and improves the quality of use.

[0027] 3. In order to facilitate the simultaneous placement of two symmetrical inner insulation boards on the inner insulation board bracket, the two inner insulation boards are separated by welding reinforcing ribs. At the same time, these reinforcing ribs further enhance the load-bearing strength of the inner insulation board bracket.

[0028] 4. In order to achieve automatic locking of the outer insulation board bracket during installation, when the slot and the spacer reinforcing rib are matched, the spacing of the wedge groove gradually decreases from the outside to the inside of the inner insulation board bracket. When the outer insulation board bracket is struck with a hammer, the upper horizontal support plate of the outer insulation board bracket is continuously clamped by the inserted angle steel, thereby achieving automatic locking of the outer insulation board bracket during installation.

[0029] 5. To meet construction requirements, the dimensions of the inner insulation board bracket must satisfy L1=T1, so that the inner and outer insulation boards will be in contact with each other; the dimensions of the outer insulation board bracket must satisfy T2 / 2<L2<T2, so that the outer insulation board bracket will be hidden in the gap, which is not only more aesthetically pleasing, but also saves materials.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figures 1 to 6 As shown, a staggered passive building exterior wall is used for the installation of passive low-energy building exterior walls. It includes an inner insulation board bracket 1 fixed to the wall surface, and an outer insulation board bracket 2 fixedly installed on the inner insulation board bracket 1. Each inner insulation board bracket 1 has two symmetrical inner insulation boards 3 placed on it, wherein the inner insulation boards 3 are rock wool boards. The outer insulation board bracket 2 has one outer insulation board 4 located between the two inner insulation boards 3. The outer insulation board 4 is also a rock wool board. At this time, the gaps between all the inner insulation boards 3 and all the outer insulation boards 4 in the vertical direction are staggered. There is a certain height difference between the horizontal support plate in the inner insulation board bracket 1 and the lower horizontal support plate in the outer insulation board bracket 2. At this time, the gaps between all the inner insulation boards 3 and all the outer insulation boards 4 in the horizontal direction are staggered. A connecting piece 5 for supporting the outer insulation board 4 is fixedly installed between each two adjacent outer insulation board brackets 2.

[0046] Because the inner insulation board bracket 1 and the outer insulation board bracket 2 in the staggered passive building exterior wall are staggered by a certain height difference, after the insulation board is laid, the gaps between all the inner insulation boards 3 and all the outer insulation boards 4 are staggered, avoiding the phenomenon of through gaps and effectively blocking the thermal bridge effect; the connecting piece 5 further strengthens the connection between two adjacent outer insulation board brackets 2, which can suppress the deformation of the outer insulation board brackets 2, thereby preventing the insulation board from shifting downward.

[0047] like Figures 5 to 6 As shown, the inner insulation board bracket 1 is formed by integral stamping of L-shaped sheet metal; the outer insulation board bracket 2 is formed by integral stamping of Z-shaped sheet metal; and the connecting piece 5 is formed by integral stamping of I-shaped sheet metal. In order to improve the rigidity and strength of the inner insulation board bracket 1, the outer insulation board bracket 2, and the connecting piece 5, all three are integrally stamped of sheet metal using molds, which facilitates mass production and improves the quality of use.

[0048] like Figures 7 to 8As shown, the inner insulation board bracket 1 has internally welded reinforcing ribs 6 that divide the left and right sides equally. In order to facilitate the simultaneous placement of two symmetrical inner insulation boards 3 on the inner insulation board bracket 1, the two inner insulation boards 3 are separated by welding the reinforcing ribs 6. At the same time, the reinforcing ribs 6 further enhance the load-bearing strength of the inner insulation board bracket 1.

[0049] like Figures 7 to 8 As shown, insertable angle steels 7 are welded and fixed to both sides of the reinforcing rib 6. Wedge-shaped grooves 8 are spaced between the insertable angle steels 7 and the transverse support plate of the inner insulation board bracket 1. The spacing of the wedge-shaped grooves 8 gradually decreases from the outside to the inside of the inner insulation board bracket 1. A slot 10 is provided in the middle of the upper transverse support plate of the outer insulation board bracket 2, which can engage with the reinforcing rib 6 for limiting. To achieve automatic locking of the outer insulation board bracket 2 during installation, when the slot 10 engages with the reinforcing rib 6 for limiting, the upper transverse support plate of the outer insulation board bracket 2 is continuously clamped by the insertable angle steels 7 when the outer insulation board bracket 2 is struck with a hammer, thus achieving automatic locking of the outer insulation board bracket 2 during installation.

[0050] like Figure 7 As shown, the vertical support plate of the inner insulation board bracket 1 has round holes 9 located on both sides of the spacer ribs 6. The inner insulation board bracket 1 is fixed to the wall by installing expansion screws into the round holes 9. In order to fix the inner insulation board bracket 1, it can be quickly fixed by installing expansion screws into the round holes 9.

[0051] like Figures 9 to 10 As shown, the length of the vertical support plate of the outer insulation board bracket 2 is 150-250mm. In order to achieve the vertical misalignment of the outer insulation board 4 and the inner insulation board 3, the length of the vertical support plate of the outer insulation board bracket 2 is designed to be 150-250mm, which can effectively stagger the gap between the outer insulation board 4 and the inner insulation board 3.

[0052] like Figures 9 to 10 As shown, multiple evenly distributed triangular reinforcing ribs 11 are welded and fixed between the lower horizontal support plate and the vertical support plate of the outer insulation board bracket 2. In order to improve the strength of the outer insulation board bracket 2, the triangular reinforcing ribs 11 are welded to prevent the outer insulation board bracket 2 from deforming.

[0053] like Figures 9 to 11As shown, both ends of the lower horizontal support plate of the outer insulation board bracket 2 are provided with elongated holes 12, and both ends of the connecting piece 5 are provided with elongated holes 13. The outer insulation board bracket 2 and the connecting piece 5 are fixed together by installing rivets in the elongated holes 12 and 13. In order to fix the outer insulation board bracket 2 and the connecting piece 5, the two can be quickly fixed by installing rivets in the elongated holes 12 and 13.

[0054] like Figure 12 As shown, the dimensions of the inner insulation board bracket 1 satisfy L1=T1; where L1 is the width of the horizontal support plate of the inner insulation board bracket 1, the dimensions of the inner insulation board 3 are 1200mm*600mm*T1, and T1 is the thickness of the inner insulation board 3; the dimensions of the outer insulation board bracket 2 satisfy T2 / 2<L2<T2; where L2 is the width of the lower horizontal support plate of the outer insulation board bracket 2, the dimensions of the outer insulation board 4 are 1200mm*600mm*T2, and T2 is the thickness of the outer insulation board 4. To meet construction requirements, since the dimensions of the inner insulation board bracket 1 satisfy L1=T1, the inner insulation board 3 and the outer insulation board 4 will be in contact with each other; since the dimensions of the outer insulation board bracket 2 satisfy T2 / 2<L2<T2, the outer insulation board bracket 2 will be hidden in the gap, which is not only more aesthetically pleasing but also saves materials.

[0055] The working principle of this utility model:

[0056] The staggered joint cladding for passive building exterior walls is implemented according to the following steps:

[0057] S1. First, lay out the positioning lines and install the bracket at the interval between each natural floor. Use a laser line projector to determine the horizontal line on the wall as the bottom positioning line of the bracket; mark a vertical line every 1200mm as the middle positioning line of the bracket.

[0058] S2. Install the inner insulation board bracket 1 according to the positioning line, and use expansion bolts to fix the inner insulation board bracket 1 to the wall. The effective fixing depth of the expansion bolts in the base wall should not be less than 50mm.

[0059] S3. Clean the base wall. After cleaning, place the inner insulation board 3 on both sides of the reinforcing rib 6 in the middle of the inner insulation board bracket 1. Then, glue the inner insulation board 3 to the wall one by one from one end. The inner insulation board 3 is glued in a full-adhesion manner, and the gap between any two adjacent inner insulation boards 3 is no more than 2mm. Then, fill the gap with polyurethane foam to complete the installation of the inner insulation board 3. Figure 1 As shown;

[0060] S4. Insert the upper horizontal support plate of the outer insulation board bracket 2 into the wedge groove 8 of the inner insulation board bracket 1, and gently tap it with a hammer until the outer insulation board bracket 2 is completely locked.

[0061] S5. Use connecting piece 5 to connect two adjacent outer insulation board brackets 2 to make the brackets a whole. The connecting piece 5 is quickly fixed by rivets to improve construction efficiency.

[0062] S6. Place the outer insulation board 4 on the outer insulation board bracket 2, positioned between the two inner insulation boards 3. At this point, the vertical gaps between the inner insulation board 3 and the outer insulation board 4 are staggered. The lower horizontal support plate of the outer insulation board bracket 2 is offset vertically from the horizontal support plate of the inner insulation board bracket 1 by 150-250mm. At this point, the horizontal gaps between the inner insulation board 3 and the outer insulation board 4 are staggered. Then, glue the outer insulation board 4 piece by piece onto the inner insulation board 3 from one end, using a full-gluing method. Ensure that the gap between any two adjacent inner insulation boards 3 is no greater than 2mm. Fill with polyurethane foam to complete the staggered installation of the insulation boards. Figure 3 As shown;

[0063] S7. After the staggered joints of the insulation boards are laid, apply a finishing mortar to the outer insulation board 4. Apply the prepared finishing mortar evenly to the outer insulation board 4, then stretch the cut mesh cloth tightly onto the bottom finishing mortar. While it is still wet, use a trowel to press the mesh cloth into the mortar, and smooth the polymer mortar from the center up and down and left and right.

[0064] S8. When the first layer of plastering mortar has dried slightly and hardened to the point where it can be touched, the anchor bolts can be installed. After the anchor bolts are installed, the second layer of plastering mortar can be applied. The plastering and mesh construction methods are the same as the previous one. After the mesh is buried, the plastering mortar is used to smooth it.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
