Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a waterproof node structure at a plain concrete exterior wall and a construction method thereof. Background Art

[0002] Traditionally, waterproof materials are used at the outer wall of the basement top plate to ensure the waterproof effect. However, in recent years, there are more and more cases of fair-faced concrete being used in projects. Designers choose fair-faced concrete mainly to retain the original color of the concrete. There is no decoration on the outside, usually the original color of the fair-faced concrete, and the outside can be painted with protective agent.

[0003] At present, the waterproof treatment of the junction between the exterior wall and the outdoor at the basement ceiling is usually carried out by plastering or adding other decorative measures on the outside of the upper waterproof material. The waterproof effect can meet the requirements, but the decorative effect cannot meet the requirements of the outside of the plain concrete. Summary of the invention

[0004] In order to overcome the defects of the prior art, a waterproof node structure at the exterior wall of fair faced concrete and a construction method thereof are provided to solve the problem that the waterproof treatment of the junction between the exterior wall and the outdoor at the basement top plate cannot meet the requirements of the decorative effect of the exterior of fair faced concrete.

[0005] In order to achieve the above object, a waterproof node structure at a plain concrete exterior wall is provided, comprising:

[0006] A waterproofing membrane is laid on a basement roof, a plain concrete exterior wall is cast on the basement roof, a closing groove is formed on the outer side of the plain concrete exterior wall, the closing groove is arranged along the width direction of the plain concrete exterior wall, the waterproofing membrane is turned over and laid along the wall surface of the plain concrete exterior wall, the upper side of the waterproofing membrane is installed in the closing groove, an outdoor floor layer is cast on the waterproofing membrane, and an assembly groove is formed between the outdoor floor layer and the wall root of the plain concrete exterior wall;

[0007] Imitation fair-faced concrete decorative panels are sealed in the notches of the closing grooves;

[0008] A drainage ditch is installed in the assembly groove, and the top of the drainage ditch is arranged below the closing groove.

[0009] Furthermore, the two opposite sides of the imitation fair-faced concrete decorative panel are respectively overlapped with the outer sides of the fair-faced concrete exterior wall on the opposite sides of the closing groove, and the inner side of the imitation fair-faced concrete decorative panel is formed with filling ridges, and the filling ridges are embedded in the closing groove.

[0010] Furthermore, a mortar chamfer is poured in the inner corner between the basement ceiling and the base of the fair-faced concrete exterior wall.

[0011] Furthermore, the outer side of the mortar chamfer is coated with waterproof mortar.

[0012] Furthermore, a pebble layer is laid on the top of the drainage ditch, and the pebble layer is flush with the top surface of the outdoor floor layer.

[0013] The present invention provides a construction method for a waterproof node structure at a plain concrete exterior wall, comprising the following steps:

[0014] When pouring the exposed concrete exterior wall on the basement top plate, a pressure strip is installed on the inner side of the outer formwork of the exposed concrete exterior wall, so that a closing groove is formed on the outer side of the exposed concrete exterior wall after the formwork is removed;

[0015] Laying a waterproofing coiled material on the basement roof, laying the waterproofing coiled material on the wall surface of the exposed concrete exterior wall, and installing the upper side of the waterproofing coiled material in the closing groove;

[0016] Installing the imitation fair-faced concrete decorative plate in the closing groove to seal the notch of the closing groove;

[0017] An outdoor floor layer is cast on the waterproof coiled material, and an assembly groove is formed between the outdoor floor layer and the base of the exposed concrete exterior wall;

[0018] Install a drainage ditch in the assembly groove so that the top of the drainage ditch is arranged below the closing groove

[0019] The beneficial effect of the present invention is that the waterproof node structure at the exterior wall of the fair-faced concrete of the present invention can effectively ensure the closing of the waterproof material by setting a closing groove on the exterior wall of the fair-faced concrete. The groove at the closing groove can be used to close the waterproof material. The outer side of the fair-faced concrete exterior wall is provided with an imitation fair-faced concrete decorative plate that is consistent with the color of the concrete to effectively hide the waterproof node and ensure the waterproof effect. On the other hand, the waterproof node structure at the exterior wall of the fair-faced concrete of the present invention can effectively solve the problem of insufficient flooding height by setting a landscape drainage ditch on the outer side of the fair-faced concrete exterior wall. After forming, there is no water accumulation at the foot of the exterior wall, which can achieve a good waterproof effect.

[0020] The waterproof node structure at the fair-faced concrete exterior wall of the present invention effectively ensures the molding effect of the fair-faced concrete exterior wall and the treatment of the waterproof node between the fair-faced concrete exterior wall and the basement top plate while ensuring the waterproof effect, and is both beautiful and practical.
