Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a rib-penetrating sandwich thermal insulation wall structure. Background Art

[0002] Under the requirement of the country to vigorously promote the development of green buildings, the insulation performance and energy-saving standards of building exterior walls are constantly improving. In terms of the structure of exterior wall insulation, there are currently four main types: external insulation, internal insulation, sandwich insulation and self-insulation. In comparison, the external insulation of the wall is easy to fall off, leak and not durable; the internal insulation of the wall occupies indoor space and has problems such as cold and hot bridges; the insulation performance of the self-insulating wall decays greatly over time and is not suitable for colder areas; the sandwich insulation wall has relatively good structural rationality, relatively stable insulation performance, good durability and weather resistance of the wall structure, and is a generally recognized form of insulation wall.

[0003] In the prior art, external insulation is mostly used as a thermal insulation method, and the external thermal insulation material is basically anchor-bonded. Considering that the wall base should not be added with weight, the external finish can only use lightweight paint or real stone paint, etc., which limits the building's exterior wall materials. And from the long-term use of anchor-bonded external thermal insulation, there will be problems such as cracking, warping, and falling off, which poses a great safety hazard. Some regions have required the recommendation of sandwich insulation methods or the use of dry-hanging external insulation and internal insulation methods. However, the existing sandwich insulation wall methods mainly use external prefabricated concrete sandwich insulation panels and single-sided prefabricated sandwich insulation cast-in-place panels, which are generally suitable for buildings with a high degree of standardization. They are relatively technically difficult and costly. Utility Model Content

[0004] The utility model aims to provide a rib-penetrating sandwich thermal insulation wall structure in view of the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A reinforced sandwich insulation wall structure comprises an inner and outer double-layer wall, and a sandwich insulation layer located in the middle of the double-layer wall; the double-layer wall is built of standard building blocks, and the sandwich insulation layer is built of sandwich insulation blocks; a plurality of holes are vertically spaced inside the standard building blocks, and perforated vertical reinforcements penetrate the holes of the standard building blocks to form a vertical connection of the double-layer wall; horizontal tie bars are connected to the perforated vertical reinforcements along the thickness direction of the double-layer wall to form a lateral connection of the double-layer wall.

[0007] Furthermore, the outer wall of the double-layer wall is built with standard blocks along the outer edge of the cantilever of the structural beam and slab, and the inner wall of the double-layer wall is built with standard blocks along the outer edge of the structural beam and column.

[0008] Furthermore, the space between the standard building blocks and the bottom surface of the structural beam slab is filled with adjustable building blocks.

[0009] Furthermore, the two adjacent standard building blocks are bonded together by masonry mortar, and the space between the two adjacent adjustment building blocks is filled with masonry mortar.

[0010] Furthermore, the outer edge of the cantilever plate of the structural beam plate is covered with thermal insulation mortar.

[0011] Furthermore, the standard building blocks are lightweight aerated concrete building blocks.

[0012] Furthermore, the sandwich insulation block is selected from one or more of rock wool board, composite cement foam insulation board, foam ceramic insulation board, polystyrene board, phenolic board and extruded board.

[0013] Furthermore, the diameter of the perforated vertical reinforcement is 4 mm to 6 mm, and the length is 800 mm to 1000 mm. The diameter of the horizontal tie reinforcement is 4 mm to 6 mm, and the length is less than the thickness of the double-layer wall.

[0014] The utility model is beneficial in that: the rib-penetrating sandwich insulation wall structure of the utility model adopts a masonry method for a double-layer wall composite insulation layer to form a new double-layer sandwich insulation wall with a constant total thickness, and at the same time adopts built-in perforated vertical reinforcement in the blocks for vertical connection, and S-shaped horizontal tie bars are used for horizontal connection between the double walls, thereby improving the overall stability of the wall.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] Combination Figures 1 to 4 As shown, the rib-penetrating sandwich insulation wall structure disclosed in the utility model includes an inner and outer double-layer wall, and a sandwich insulation layer located in the middle of the double-layer wall. The double-layer wall is built by standard building blocks 1, and the sandwich insulation layer is built by sandwich insulation blocks 6. Standard building blocks 1 are built along the double-layer outer wall. Specifically, the outer wall of the double-layer wall is built by standard building blocks 1 along the outer edge of the cantilever of the structural beam slab, and the inner wall of the double-layer wall is built by standard building blocks 1 along the outer edge of the structural beam column, forming an overall wrapping of the insulation layer. A plurality of holes are vertically spaced inside the standard building block 1, and holes can be formed when both the joints are built and the staggered joints are built. The standard building blocks 1 can be vertically connected by inserting the perforated vertical bars 4 into the holes. At the horizontal joints of each layer of the standard building blocks 1 of the inner and outer double-layer walls, the perforated vertical ribs 4 in the standard building blocks 1 of the inner and outer double-layer walls are connected by horizontal tie bars 5 to form a lateral connection of the double-layer wall. Sandwich insulation blocks are placed between the double-layer walls built with standard building blocks 1 to form an overall stable double-layer sandwich insulation wall. Compared with other insulation methods, the sandwich insulation wall has more advantages in terms of insulation energy saving, waterproof and anti-seepage, safety and durability. It solves the safety hazards of easy detachment of external insulation, the problem of indoor space occupation and environmental protection of internal insulation, and the defects of easy failure of self-insulation. At the same time, the sandwich insulation wall provides a solid exterior wall base, improves the wall adhesion, is suitable for the laying of various decorative surface materials, and provides more possibilities for the exterior design of the building.

[0026] When the standard building blocks 1 are used to build the sandwich insulation wall to the bottom surface of the structural beam slab 9, taking into account the influence of different floor heights, the gap sizes between the topmost standard building blocks 1 and the bottom surface of the structural beam slab 9 are different, and considering that the holes in the top standard building blocks 1 cannot be inserted into the perforated vertical bars 4, the perforated vertical bars 4 in the topmost standard building blocks 1 are first pulled out, fixed with masonry mortar 3, and the adjustment building blocks 2 (300mm wide, 100mm thick, 100-250mm high) are horizontally embedded between the perforated vertical bars 4, and finally the gaps are filled with masonry mortar 3.

[0027] The standard block 1 is a perforated lightweight aerated concrete block, preferably a lightweight autoclaved aerated concrete block (ALC), preferably 600mm long, 100mm wide, and 300mm high, with equidistant circular holes set in the middle of the cross section, and the holes can be penetrated during staggered masonry. The adjustment block 2 is a non-standard block made of the same material as the standard block 1, 300mm long, 100mm wide, and 100-250mm high, used to fill the gap between the top of the wall and the beam slab of the standard block 1. Masonry mortar 3 is an adhesive material for masonry between blocks. The perforated vertical reinforcement 4 is a steel bar connected to the upper and lower blocks, with a diameter of 4mm-6mm and a length of 800mm-1000mm. The length can be adjusted according to the wall size and construction requirements. The horizontal tie bar 5 is a horizontal connection of the perforated vertical reinforcement 4 in the relative position between the double walls, with a diameter of 4mm-6mm and a length less than the thickness of the double wall, which is determined according to the insulation thickness spacing of the double wall. The sandwich insulation block 6 is a B1 or A grade insulation block material, selected from one or more of rock wool board, composite cement foam insulation board, foam ceramic insulation board, polystyrene board, phenolic board, and extruded board, and the size should be convenient for placement during wall construction. The cantilever board supporting the standard building block 1 is prone to form a cold bridge at the outer edge, and the insulation mortar 7 fills this place to solve the cold bridge problem at the end of the structural cantilever board.

[0028] like Figure 5 As shown, the construction method of the rib-penetrating sandwich insulation wall structure of the utility model comprises the following steps:

[0029] Step 1: build the ribbed sandwich insulation wall on the structural beam slab 9, the inner and outer layers of the wall are built with standard blocks 1, the outer side of the outer wall is flush with the outer side of the cantilever of the structural beam slab 9, the outer side of the inner wall is flush with the outer side of the structural beam column 8, and the thickness of the sandwich insulation layer is reserved between the inner and outer walls;

[0030] Step 2: After completing the masonry of one layer of standard masonry blocks 1, insert the perforated vertical reinforcement 4 into the vertical holes of the standard masonry blocks 1. The length of the perforated vertical reinforcement 4 can be adjusted according to the convenience of masonry to form a vertical connection between the upper and lower walls;

[0031] Step 3: Fill the sandwich insulation block 6 in the space reserved between the inner and outer walls, then use masonry mortar 3 to fix the perforated vertical reinforcement 4, and use horizontal tie bars 5 to tie and connect the corresponding perforated vertical reinforcement 4 of the inner and outer walls. The length of the horizontal tie bars 5 is determined according to the thickness spacing of the double wall insulation to form a horizontal tie connection of the double wall;

[0032] Step 4: Then, the second layer is built with standard building blocks 1, and the adjacent two layers of standard building blocks 1 are built with butt joints or staggered joints, preferably staggered joints, and step 3 is repeated until the standard building blocks 1 are about to reach the bottom surface of the upper layer of structural beam slab 9;

[0033] Step 5: Pull out the perforated vertical ribs 4 in the topmost standard building block 1 to the bottom surface of the structural beam slab 9, fix it with masonry mortar 3, horizontally embed the adjustable building block 2 between the perforated vertical ribs 4, and use masonry mortar 3 to fill the gap between two adjacent adjustable building blocks 2, and finally use insulation mortar 7 to fill the outer end of the cantilever of the structural beam slab 9. At this point, the ribbed sandwich insulation wall structure is completed as a whole.

[0034] The rib-piercing sandwich insulation wall structure construction method of the utility model is suitable for the current large-scale and wide-area lightweight aerated block wall construction method, which combines wall construction and insulation construction in one process, saves construction time and improves construction efficiency. At the same time, the modular perforated standard blocks are used, which are convenient for standardized production, transportation, and installation, have a wide range of large-scale applicable environments, save costs, are conducive to large-scale promotion, and have good economic benefits.
