Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building node construction, in particular to a node for a steel column and a water-stopping steel plate on an outer wall of a basement. Background Art
[0002] In architectural design, basement waterproofing is a very important link. The rationality of basement waterproofing and the quality of construction directly affect the quality of the product and the user experience during use. Since the basement has high maintenance costs and is difficult to repair and has high costs, waterproof structural measures need to be taken during the design stage. During the design, in order to reduce the protrusion of the steel columns in the basement, the steel columns are often partially embedded in the concrete exterior wall. In traditional concrete buildings, the concrete columns and the basement exterior walls are cast as a whole, and there is usually only one horizontal secondary casting cold joint, which makes waterproofing less difficult. In prefabricated steel structure buildings, in addition to a horizontal secondary casting cold joint, the steel column itself has two vertical secondary casting joints. Therefore, the waterproofing of the basement steel columns and concrete exterior walls is one of the current pain points and difficulties, and the problem of waterproofing and anti-leakage is prominent. Utility Model Content
[0003] In order to solve the problems in the background technology and ensure the functional requirements of waterproofing the steel columns and the concrete exterior walls of the basement in prefabricated steel structure buildings, the purpose of the utility model is to provide a water-stop steel plate node between the steel columns and the basement exterior walls, which can be widely used in the waterproof and anti-leakage treatment nodes of the steel columns and concrete exterior walls of prefabricated steel structure buildings.
[0004] The technical solution adopted by the utility model is as follows:
[0005] The node includes a steel column, a water-stop steel plate, a basement floor, a reinforced concrete outer wall, and a foundation cushion layer; the basement floor is connected to the foundation cushion layer by casting as an integrated structure, the reinforced concrete outer wall is fixedly connected to the upper surface of the basement floor, and a construction cold joint is reserved in the reinforced concrete outer wall during the construction process. The bottom of one side of the reserved construction cold joint in the reinforced concrete outer wall protrudes outward along the thickness direction of the reinforced concrete outer wall to form a flange structure, and the flange structure is used to fix the cast water-stop steel plate, and the steel column is fixedly connected to the basement floor and cast inside the reinforced concrete outer wall.
[0006] The waterstop steel plate is mainly composed of a base plate, two inclined plates and two horizontal extension plates. The two horizontal extension plates are symmetrically arranged on both sides of the length direction of the base plate, and the horizontal extension plates are arranged parallel to the base plate. The two horizontal extension plates are welded to the two ends of the waterstop steel plate through the inclined plates, and the base plate and the two inclined plates form a U-shaped bending structure. The opening of the U-shaped bending structure faces the steel column. The base plate in the waterstop steel plate is cast inside the flange structure.
[0007] The outer wall of the steel column is connected to a plurality of rows of steel column groups arranged at intervals along the circumferential direction, each row of steel column groups is arranged along the length direction of the steel column, and each row of steel column groups is mainly composed of steel column bolts located in the same straight line and arranged in sequence at even intervals. The steel column bolts are arranged inside the reinforced concrete outer wall to anchor the steel column to the reinforced concrete outer wall.
[0008] The flange structure is arranged at the bottom of the reinforced concrete outer wall along the extension direction of the reinforced concrete outer wall, and the extension direction of the water stop steel plate is parallel to the length direction of the flange structure.
[0009] A layer of steel column interface agent is coated at the connection position between the steel column and the reinforced concrete outer wall.
[0010] The angle formed between the bottom plate and the inclined plate ranges from 100° to 150°.
[0011] The bottom of the steel column is fixedly connected to the basement floor through column foot anchor bolts, and concrete is poured inside the steel column.
[0012] The outer side surfaces of the reinforced concrete outer wall and the flange structure on one side of the reserved construction cold joint are both provided with an outer wall waterproof layer.
[0013] The utility model includes a steel column, a reinforced concrete outer wall, a reinforced concrete bottom plate, a steel column interface agent, a water-stop steel plate, an outer wall waterproof layer, steel bars, steel column bolts, indoor plastering mortar, etc. Concrete is poured inside the steel column of the basement, and a circle of reinforced concrete outer wall is poured along the outer side of the steel column to meet the requirements of the waterproof flooding height of the basement. During the construction of the main structure of the basement, the concrete of the bottom plate and the reinforced concrete outer wall are poured separately, and a construction cold joint is reserved inside the reinforced concrete outer wall. When the position of this construction cold joint is below the groundwater level, water seepage is likely to occur, so it is necessary to perform technical treatment on this construction cold joint during the construction process. There are many treatment methods, among which the more popular method is to set a water-stop steel plate. The water-stop steel plate here can be arranged continuously and relatively easily in the traditional concrete structure, and has a good waterproof effect. However, it is interrupted in the node between the steel column and the reinforced concrete outer wall due to the presence of the steel column, and it is not easy to be continuous.
[0014] Different from the traditional concrete column and concrete exterior wall structure, there are multiple secondary casting joints between the basement steel column and the basement exterior wall and basement floor slab cast outside the steel column. The steel column itself and the concrete exterior wall are also made of two different materials. In order to further strengthen the waterproof joints and increase the water seepage path, the plasticity of the water-stop steel plate is used to design the secondary casting joints and steel columns. This avoids the local bulge of the exterior wall caused by ensuring the usual continuity of the water-stop steel plate and reduces the casting cost of the concrete exterior wall.
[0015] In order to avoid the water-stop steel plate being interrupted by the steel column and become discontinuous and to improve the waterproofing effect, local protrusion casting is used at the steel column to avoid the water-stop steel plate being interrupted, so as to provide a continuous bypass channel for the water-stop steel plate. The local protrusion casting method can also avoid casting in the usual height direction, effectively solve the problem of horizontal discontinuity after the concrete exterior wall is out of the ground, and reduce the impact on the building facade. The continuous steel plate waterstop can change the water penetration path and extend the water penetration route, thereby further improving the waterproofing performance.
[0016] The construction method of waterproofing the basement concrete exterior wall is consistent with traditional construction methods. It is included in the node here for the completeness of the node. There is no technical innovation and it will not be elaborated.
[0017] The utility model has a complete structure, convenient and fast construction, a high degree of standardization, and can form effective steel column roof waterproofing and anti-leakage multiple defense lines, and can be widely used in the waterproof node structure of steel columns and basement exterior walls of assembled steel structure buildings.
[0018] The beneficial effects of the utility model are:
[0019] 1. Complete structure. This node method forms a complete basement cold joint waterproof structure, which solves the problems of waterproofing and leakage prevention in the structure and has a complete structure.
[0020] 2. The construction is convenient and quick. It does not affect the architectural effect after the underground exterior wall comes out of the ground, and is convenient for the arrangement of the exterior wall water dispersion.
[0021] 3. High degree of standardization. Since steel columns, water-stop steel plates and bolts are all standardized parts, the methods and materials of the nodes are highly standardized, batch cutting and batch flow construction are possible, which makes it easy to ensure quality and the workers are skilled in operation.
[0022] 4. It can effectively form multiple anti-leakage lines, change the water penetration path, extend the water penetration route, and further improve the waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS
