Description

Technical Field

[0001] The present invention relates to the field of building construction, and more specifically, to a construction method for an external wall connection node. Background Art

[0002] Currently, when construction workers are building structural beams of a building, they first build steel bars and structural beam formwork, and then pour concrete on the steel bars and structural beam formwork to form a structural beam structure.

[0003] When the exterior wall is built, the exterior wall will be formed under the structural beam by stacking cement and wall bricks. After the structural beam and exterior wall are built, hanging mesh will be installed on the exterior wall and structural beam as needed, and at the same time, plaster will be applied and bricks will be laid on the surface of the exterior wall and structural beam.

[0004] However, in the actual construction process, people found that due to the large temperature difference between day and night on the roof, the different linear expansion coefficients of the concrete and the exterior wall materials, the thermal expansion and contraction between the materials are not synchronized, which will cause large tensile and shear forces in the exterior wall. Over time, it will cause temperature cracks in the exterior wall, which will manifest as horizontal cracks under the structural beams of the building. This not only affects the appearance of the building, but also easily leads to safety hazards.

[0005] Therefore, it is necessary to propose a construction method for external wall connection nodes that solves the above problems. Summary of the invention

[0006] In order to overcome at least one defect (shortcoming) of the above-mentioned prior art, the present invention provides a method for constructing an external wall connection node.

[0007] In order to solve the above technical problems, the technical solution of the present invention is as follows: a method for constructing an external wall connection node, comprising the following steps:

[0008] S1, build the structural beams, and build the external wall under the structural beams. After the structural beams and the external wall are finalized, roughening and meshing are performed on the structural beams and the external wall;

[0009] S2, after continuously setting separation wood strips along the intersection of the exterior wall and the structural beam, a large area of ​​plastering is performed to form a plastering layer;

[0010] S3, after the plaster layer is dried and solidified, the partitioning wood strips are removed to obtain the partitioning joints, and the structural sealant is filled in the partitioning joints, and after the structural sealant is filled, the height of the structural sealant and the plaster layer is flush;

[0011] S4, pasting external wall paper bricks on the plaster layer of the external wall, pasting structural beam paper bricks on the plaster layer of the structural beam, and providing a reserved separation gap between the external wall paper bricks and the structural beam paper bricks;

[0012] S5, filling the reserved separation joint with neutral silicone weatherproof sealant, wherein the neutral silicone weatherproof sealant is flush with the height of the external wall paper bricks and the structural beam paper bricks after being filled.

[0013] Furthermore, the step S1 includes the following steps:

[0014] S11, constructing steel bars and structural beam formwork, and pouring concrete on the steel bars and structural beam formwork to form a structural beam structure;

[0015] S12, after the concrete is set, the structural beam formwork is removed;

[0016] S13, using bricks and cement to form an external wall structure below the structural beam;

[0017] S14, roughening and meshing are performed on the structural beams and external walls.

[0018] Furthermore, the step S2 includes the following steps:

[0019] S21, continuous partitioning strips are set at the junction of the exterior wall and the structural beam;

[0020] S22, after water is spread on the outer wall and the structural beam, a construction reference surface is formed on the outer wall and the structural beam through transverse reinforcement and longitudinal reinforcement;

[0021] S23, referring to the construction reference plane, plastering is performed multiple times on the exterior walls and structural beams on both sides of the partitioning wood strips over a large area to form a plastering layer.

[0022] Furthermore, the step S3 includes the following steps:

[0023] S31, after the plaster layer is dried and solidified, the partitioning wood strips are removed to obtain the partitioning joints;

[0024] S32, after cleaning the partition joint, fill the partition joint with structural sealant, and make sure that the structural sealant is flush with the height of the plaster layer after filling.

[0025] Furthermore, the step S4 includes the following steps:

[0026] S41, after leveling the plaster layer of the structural beam, affix the structural beam paper bricks on the plaster layer of the structural beam, and in order to be on the same horizontal line with the hawkbill bricks of the door and window openings, when affixing the structural beam paper bricks, the bottom edge of the structural beam paper bricks is pressed against the upper part of the structural sealant;

[0027] S42, after leveling the plaster layer of the outer wall, affix outer wall paper bricks on the plaster layer of the outer wall, wherein the top of the outer wall paper bricks is flush with the bottom of the separation seam, so that a reserved separation seam is provided between the outer wall paper bricks and the structural beam paper bricks.

[0028] Furthermore, in step S41, the bottom of the structural beam paper brick is pressed onto the structural sealant by a distance of 1.5-2 cm.

[0029] Furthermore, in step S41, the width of the reserved separation seam is 10-15 mm.

[0030] Furthermore, the step S5 includes the following steps:

[0031] S51, clean the reserved separation seam;

[0032] S52, filling the reserved separation joint with neutral silicone weatherproof sealant, and after the neutral silicone weatherproof sealant is filled, the neutral silicone weatherproof sealant is flush with the height of the external wall paper bricks and the structural beam paper bricks;

[0033] S53, apply a waterproof layer on the outside of the external wall paper bricks, neutral silicone weatherproof sealant and structural beam paper bricks.

[0034] Furthermore, the structural sealant is a weather-resistant structural sealant. In practical applications, other structural sealants may be used to seal the separation seams and reserved separation seams, which are all easily conceivable by those skilled in the art.

[0035] Furthermore, the length and width of the partitioning wooden strips are both 30 mm, and the thickness is 20 mm. In practical applications, the specific dimensions of the partitioning wooden strips can be set as needed.

[0036] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0037] The exterior wall connection node construction method disclosed in the present invention can effectively solve the tension and shear force caused by the large temperature difference between the structure beam and the exterior wall due to the large temperature difference between day and night, the different linear expansion coefficients of the concrete and the exterior wall, and the asynchronous thermal expansion and contraction between the materials, by providing a structural sealant on the outside of the structure beam and the exterior wall, and play a buffering role. Since the structure beam paper brick is hung down by 1.5-2cm, the edge of the bottom of the structure beam paper brick is pressed on the structural sealant, and neutral silicone weather-resistant sealant is filled in the reserved separation joint. In this way, even if the reserved separation joint occasionally has cracks, rainwater will not flow back, which greatly reduces the hidden danger of leakage. BRIEF DESCRIPTION OF THE DRAWINGS

In practical applications, the specific dimensions of the partition wooden strips can be set as needed.

[0074] Example

[0075] In this embodiment, when a structural beam needs to be built, the steel bars and the structural beam template are built to form the initial shape of the structural beam, and concrete is poured on the structural beam. After the concrete is set, the structural beam template is removed to obtain the structural beam 1.

[0076] After the construction of the structural beam is completed, bricks and cement are piled under the structural beam 1 to form the outer wall 2. However, the structural beam 1 and the outer wall 2 are prone to cracking and penetration of the outer wall. The reason is that the temperature difference between the roof and the outer wall is large during the day and night, and the linear expansion coefficients of the structural beam 1 and the outer wall 2 are different. The thermal expansion and contraction of the materials are not synchronized, which will generate large tensile and shear forces in the outer wall. Over time, temperature cracks will occur, which are specifically manifested as horizontal cracks formed under the structural beam 1 of the building, which not only affects the appearance of the building, but also easily leads to safety hazards.

[0077] In this embodiment, after the exterior wall 2 and the structural beam 1 are built, the exterior wall 2 and the structural beam 1 are first roughened and meshed, and partition wooden strips 3 are continuously set at the junction of the exterior wall 2 and the structural beam 1. After the partition wooden strips 3 are set, water is sprinkled on the exterior wall 2 and the structural beam 1, and a construction reference surface is formed on the exterior wall 2 and the structural beam 1 through transverse and longitudinal reinforcements. The setting of the construction reference surface can provide a reference for plastering, which is convenient for controlling the plastering thickness at each position of the structural beam 1 and the exterior wall 2. Among them, plastering needs to be carried out in multiple times. After the first layer of plaster is applied, wait for it to dry and then apply the second layer of plaster until the thickness of the plaster layer 4 reaches the design requirements.

[0078] When the thickness of the plaster layer 4 reaches the requirement and is dry, the partition strips 3 can be removed. After the partition strips 3 are removed, a straight partition seam 5 will be obtained. At this time, you only need to clean the partition seam 5 and fill the partition seam 5 with structural sealant 6. After the structural sealant 6 is filled in, make the structural sealant 6 flush with the height of the plaster layer 4.

[0079] After the structural sealant 6 is dried, tiles can be laid on the plaster layer of the structural beam 1 and the plaster layer of the external wall 2. When laying tiles, the plaster layer of the structural beam 1 and the plaster layer of the external wall 2 will be leveled first, and then the structural beam paper brick 7 will be pasted on the structural beam 1, and the external wall paper brick 8 will be pasted on the external wall 2. A reserved separation seam 9 should be provided between the structural beam paper brick 7 and the external wall paper brick 8. At this time, in order to be at the same level as the hawkbill bricks of the door and window openings, the structural beam paper brick 7 needs to be hung down 1.5-2 cm so that the edge of the bottom of the structural beam paper brick 7 is pressed against the structural sealant 6. In this way, even if the reserved separation seam 9 occasionally has cracks, rainwater will not flow back in.

[0080] After the structural beam paper bricks 7 and the external wall paper bricks 8 are laid, it is only necessary to fill the reserved separation joints 9 with neutral silicone weatherproof sealant 10. After the neutral silicone weatherproof sealant 10 is filled, the neutral silicone weatherproof sealant 10 is made flush with the height of the external wall paper bricks 8 and the structural beam paper bricks 7. Finally, a waterproof layer can be applied to the outer sides of the external wall paper bricks 8, the neutral silicone weatherproof sealant 10 and the structural beam paper bricks 7 as needed to complete the construction. By such an arrangement,

[0081] In the figure, the description of the positional relationship is only for illustrative purposes and should not be understood as a limitation on this patent; obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
