Description

Technical Field

[0001] The utility model relates to the technical field related to the blocking of structural walls, in particular to a prefabricated blocking structure for structural exterior walls. Background Art

[0002] In the prior art, the conventional practice is to drill holes, plug the two ends, and place foam glue in the middle. However, in this way, when residents decorate the wall, holes will be drilled in the wall to penetrate the foam glue, forming through holes.

[0003] In the prior art, although there are prefabricated plugging structures, most of them are cuboids, lack of guide assembly, and are directly cast by mortar, which easily leads to a cooling effect and affects the sealing performance. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated blocking structure for a structural exterior wall, which isolates the blocking point from the outside of the structural wall by adding an isolation layer, thereby cutting off the cold bridge effect and improving the sealing performance; at the same time, the added multiple sections achieve multiple effects such as guiding entry and reinforcement.

[0005] In order to achieve the above technical effects, the utility model is implemented through the following technical means.

[0006] Prefabricated blocking structures for structural exterior walls, including,

[0007] A blocking structure body, wherein the outer surface of the blocking structure body forms a guide surface for guiding the blocking structure body into the structural wall;

[0008] The blocking structure body comprises a guide section, a connecting section and a reinforcement section, wherein a connecting piece runs through the connecting section, and the connecting piece extends into the guide section and the reinforcement section, so that the guide section and the reinforcement section are integrated with the connecting piece;

[0009] An isolation layer is formed along the length direction of the blocking structure body to isolate the blocking area and the outside of the structure wall;

[0010] Assembly components are respectively arranged between the connecting section, the guiding section and the reinforcing section.

[0011] Furthermore, the guide surface is an inclined surface structure inclined toward the structural wall, and an acute angle is formed between the inclined surface structure and a center line of the blocking structure body.

[0012] Further, the side portion of the guide section forms a portion of the guide surface, and the guide section forms a guide path from low to high.

[0013] Furthermore, from top to bottom, the blocking member body forms a truncated cone structure with a gradually increasing cross-sectional area, and the guide section is located at the end with a smaller cross-sectional area.

[0014] Furthermore, the sum of the lengths of the guiding section and the reinforcing section is greater than or equal to the length of the connecting section.

[0015] Furthermore, the guide section and the reinforcement section are both mortar bars, and the mortar bar structure length of the guide section is greater than the mortar bar length of the reinforcement section.

[0016] Furthermore, the connecting section is a heat-insulating structure, and the heat-insulating structure forms a plurality of the isolation layers.

[0017] Furthermore, the assembly component includes a step-shaped protrusion and a groove structure matching the step-shaped protrusion, and one of the groove structure and the step-shaped protrusion is arranged on both sides of the connecting section, and the other is arranged on the guiding section or the reinforcing section.

[0018] Furthermore, the depth of the groove structure is 2-5 mm.

[0019] Furthermore, the connecting piece is a round rod structure, and the surface of the round rod structure is a smooth surface or a threaded surface.

[0020] The beneficial effects of the utility model are as follows:

[0021] In the utility model, an isolation layer is added, thereby achieving a good effect of cutting off the cold bridge effect. Furthermore, during the blocking process, the temperature transfer between indoor and outdoor can be cut off, so that a relatively constant temperature is formed at the blocking location, reducing the condensation of dew in the wall of the exterior wall, causing "tears", "sweating", "mildew", dampness and mildew in the house.

[0022] In the utility model, the entire blocking structure is changed into a guide section, a connection section and a reinforcement section, so that the blocking structure can enter the blocked hole relatively easily, and the reinforcement section makes the part close to the outer wall strong, and cooperates with the isolation layer, which not only isolates the outside world well, but also makes the part that is easily in contact with the outside world strong.

[0023] The utility model has a simple structure, and the entire blocking structure can be prefabricated and assembled in advance. During use, the blocking is completed by directly guiding the guide surface, and the assembly efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0029] Refer to the attached Figure 1-2 As shown, the utility model discloses a prefabricated blocking structure for a structural exterior wall, including a blocking structure body 100, the outer surface of the blocking structure body 100 forms a guiding surface 110 for guiding the blocking structure body into the structural wall; the blocking structure body 100 includes a guiding section 200, a connecting section 300 and a reinforcing section 400, a connecting piece 500 passes through the connecting section 300, and the connecting piece 500 extends into the guiding section 200 and the reinforcing section 400, so that the guiding section 200 and the reinforcing section 400 are integrated with the connecting piece 500; along the length direction of the blocking structure body 100, an isolation layer 120 is formed to isolate the blocking area and the outside of the structural wall; between the connecting section 300 and the guiding section 200 and the reinforcing section 400, assembly components are respectively provided for assembly connection.

[0030] In this embodiment, according to the specific structure, it is divided into multiple sections, so that each section has its own independent function and effect. In the plugging, it plays the role of guiding assembly, connection and reinforcement, especially the rear reinforcement section, which can ensure the firmness after plugging.

[0031] In the utility model, the connecting piece is used to penetrate and complete the assembly with the guide section and the reinforcement section. Compared with a separate gluing method, the whole prefabricated blocking structure is formed, the connection is firm, and the structural stability is good.

[0032] In the utility model, the blocking structure is used to divide the indoor and outdoor, or to isolate two spaces, and the added isolation layer is used to isolate the blocking hole from the outside of the structural wall, especially to achieve the mutual transfer of air temperature, thereby avoiding the cold bridge effect caused by temperature difference, ensuring leakage prevention and improving sealing.

[0033] Refer to the attached Figure 1-2As shown, in this embodiment, for the convenience of processing, the guide surface 110 is an inclined surface structure inclined toward the structural wall, and an acute angle is formed between the inclined surface structure and the center line of the blocking structure body 100. In this embodiment, the angle between the guide surface and the center line of the blocking structure body 100 is preferably 20°-40°. Within this range, a surface that is not very close to the center line is formed, so that there is a certain width variation range, and the inclined surface is a little steep, which is convenient for insertion and entry to achieve assembly.

[0034] In this embodiment, the guide section 200 is only a part of the guide surface, and at the same time, the guide path formed by it from low to high makes it easier for the lower part to enter the blocking port, and then guides the higher part to enter the blocking port.

[0035] Specifically, in order to facilitate production and processing and achieve a smooth and beautiful appearance, the plugging member body 100 forms a truncated cone structure with a gradually increasing cross-sectional area from top to bottom, and the guide section 200 is at the end with a small cross-sectional area. The outer surface is a truncated cone structure, and its outer surface is smooth, which makes it easy to enter the truncated cone-shaped plugging port to complete the plugging.

[0036] To ensure firmness, the sum of the lengths of the guide section 200 and the reinforcement section 400 is greater than or equal to the length of the connection section 300. At this time, the connection section is only one section and accounts for a small proportion, but due to the existence of the connector 500, the stability of the entire structure is ensured.

[0037] In order to reduce the cost on the construction site, the guide section 200 and the reinforcement section 400 are both mortar rods, and the mortar rod structure length of the guide section 200 is greater than the mortar rod length of the reinforcement section 400. Therefore, the mortar content is high and the cost is low. In this case, the guide section is the longest in structure, which is more convenient for guiding and assembling.

[0038] In actual use, the connecting section 300 is a heat-insulating structure, and the heat-insulating structure forms a plurality of the isolation layers. In this embodiment, the heat-insulating materials include the following:

[0039] 1. Glass wool: Glass wool is a thermal insulation material made of glass fiber, which has good thermal insulation and sound absorption properties. Its bulk density is generally between 12-96kg / m", light and soft, suitable for use in walls, roofs and floors.

[0040] 2. Polystyrene (EPS): EPS is a thermal insulation material made from petrochemical product polystyrene, which has good thermal insulation performance and weather resistance. Its bulk density is generally between 10-35kg', which is light and easy to install and process.

[0041] 3. Polyurethane: Polyurethane is a thermal insulation material made of isocyanate as the main raw material, which has good thermal insulation and fire resistance. Its bulk density is generally between 30-50kg / m:, which is light but relatively heavy, and is suitable for structures such as walls and roofs.

[0042] 4. Tridacnamate: Tridacnamate is a thermal insulation material made of silicate fiber, which has excellent high temperature resistance and fire resistance. Its bulk density is generally between 200-800kg / m3, which is relatively heavy and suitable for fire-resistant walls and high temperature places.

[0043] 5. Desulfurized gypsum: Desulfurized gypsum is a thermal insulation material made of desulfurized gypsum powder as the main raw material, which has good thermal insulation and moisture absorption properties. Its bulk density is generally between 500-700kg / m', which is heavier but relatively light, and is suitable for use in walls and roofs.

[0044] In this embodiment, the above-mentioned thermal insulation material can form a relatively good cold bridge cutting effect and perform temperature isolation.

[0045] Furthermore, the assembly component includes a step-shaped protrusion and a groove structure matching the step-shaped protrusion, and one of the groove structure and the step-shaped protrusion is arranged on both sides of the connecting section 300, and the other is arranged on the guide section 200 or the reinforcement section 400. The assembly mode of the boss and the groove, in conjunction with the connecting piece, makes the contact surface more and firmer, and at this time, an inclined surface can be formed on the contact surface of the boss and the side of the groove to improve stability.

[0046] In a specific product, the depth of the groove structure is 2-5 mm. Since the length of the entire plugging structure body is generally 150-300 cm, the depth of the groove is generally not suitable to be set too deep.

[0047] In this embodiment, the connector 300 is a round rod structure, and the surface of the round rod structure is a smooth surface or a threaded surface. When the threaded surface is selected, the three sections are assembled directly through the bonding surface, and when the smooth surface is selected, the assembly method of assembling components can be considered.

[0048] See attached Figure 1-2 As shown, the prefabricated plugging structure for the structural exterior wall in this embodiment specifically includes a connecting section 300 made of thermal insulation material, and the guide sections and reinforcement sections on both sides are made of dry hard mortar, and then the connecting piece 500 passing through the connecting section 300 is directly constructed on the outer periphery of the connecting piece 500 to form the guide section and the reinforcement section. The entire plugging structure body 100 is 200 cm long, and the entire structure forms a truncated cone structure. The starting end diameter of the smallest end of the guide section is 1.5 cm, and the diameter of the widest part of the reinforcement section is 2.5 cm, so as to form a truncated cone structure. At this time, the length of the guide section and the connecting section is 70 cm, and the length of the reinforcement section is 60 cm.

[0049] The method of the utility model has a simple structure, is directly prefabricated, has low cost, can be used directly, has a simple use method, is easy to assemble, and has a good later blocking effect.

[0050] The sealing structure in the utility model has good sealing performance, so it is mainly used for sealing holes in the internal and external structural walls of ultra-low energy consumption or zero energy consumption buildings. At this time, it can meet the sealing requirements of passive houses formed by ultra-low energy consumption. In addition, the sealing structure in the utility model is also suitable for sealing holes in the internal and external structural walls of ordinary buildings.
