Detailed Description
The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the anti-floating anchor rod waterproof node structure comprises an anchor rod 1 penetrating through a concrete cushion 2, and a cement-based permeable crystalline waterproof layer 3 formed by cement-based permeable crystalline coating is laid on the concrete cushion 2.
The anchor rod 1 is sleeved with a gasket 4, the gasket 4 is annular and falls on the surface of the cement-based permeable crystalline waterproof layer 3.
Lay the first coil material waterproof layer 5 that constitutes by SBS waterproofing membrane on the cement base infiltration crystallization waterproof layer 3, during stock 1 penetrated the rod hole that first coil material waterproof layer 5 set up to make stock 1 run through first coil material waterproof layer 5 through the rod hole. First coil material waterproof layer 5 is pressed on gasket 4 for make first coil material waterproof layer 5 and cement base infiltration crystallization waterproof layer 3 can form the centre gripping to gasket 4.
A second waterproof roll sheet 6 made of an SBS waterproof roll is laid on the first waterproof roll sheet 5, and the second waterproof roll sheet 6 is folded upward to form a cylindrical projection 61.
The boss 61 of tube-shape has accommodation space 62, and accommodation space 62 is upwards passed to stock 1, and accommodation space 62 intussuseption is filled with polyurethane 10, and polyurethane 10 bottom is fallen on first coiled material waterproof layer 5, with annular space packing and the closing cap between stock 1 and the pole hole, makes two coiled material waterproof layers all sealed by complete, realizes waterproofly.
Second coiled material waterproof layer 6 upper berth is equipped with pea gravel concrete protective layer 7, and pea gravel concrete protective layer 7 top surface is higher than the top of bellying 61 for bury polyurethane 10 in pea gravel concrete protective layer 7 totally, thereby form the protection to polyurethane 10 and second coiled material waterproof layer 6, avoid the top structure to push down the stress that produces and form the damage to it.
Waterproof bottom plates 8 are laid on the fine stone concrete protective layers 7 to form the ground of the underground structure of the building, and meanwhile, water is prevented.
Gasket 4 falls on level and smooth and stable cement base infiltration crystallization waterproof layer 3, forms the support to polyurethane 10 on first coil of material waterproof layer 5 and the first coil of material waterproof layer 5, avoids polyurethane 10 to break away from the whereabouts, keeps its stable in structure to improve node structure's waterproof performance.
The polyurethane can be filled into the accommodating space 62 by pressurizing, and after the fine aggregate concrete protective layer 7 is covered, the polyurethane sealed in the accommodating space 62 can have a certain pressure. The polyurethane of packing in accommodation space 62, not only seal, play waterproof, and its dead weight and the pressure of sealing in accommodation space 62 interior production, can form the pushing down to first coil of material waterproof layer 5, thereby increase first coil of material waterproof layer 5 and cement base infiltration crystallization waterproof layer 3 and carry out the compactness of centre gripping to gasket 4, make first coil of material waterproof layer 5 and gasket 4's connecting portion and cement base infiltration crystallization waterproof layer 3 and gasket 4's connecting portion can both obtain good sealing, thereby improve node structure's waterproof performance.
In order to further improve the stability of the polyurethane 10 in the accommodating space 62, the sheath 9 is mounted on the boss 61, and the cylindrical body of the sheath 9 is sleeved on the boss 61, and the inner wall of the cylindrical body is in contact fit with the outer wall of the boss 61.
Because the accommodating space 62 is filled with the polyurethane 10, the stress of the polyurethane 10 acts outwards, so that the protruding portion 61 is pushed outwards in a certain radial direction, and the protruding portion 61 is easy to open and crack. The sheath 9 body forms radial support to bellying 61, avoids bellying 61 to open, prevents that the bellying from producing the fracture to avoid polyurethane 10 to spill from the position of bellying fracture, guarantee polyurethane 10's stability, improve the waterproof performance of node structure.
Since the fine aggregate concrete protective layer 7 is covered on the second roll waterproof layer, the fine aggregate concrete protective layer 7 can generate stress acting to the inner side, so that the convex portion 61 is pushed radially and inwardly to a certain extent, the convex portion 61 is easily retracted, the accommodating space 62 is reduced, and the polyurethane 10 overflows. The sheath 9 body forms the support to fine aggregate concrete protective layer 7, avoids it to form inside pushing to bellying 61 to avoid polyurethane 10 to spill over, guarantee polyurethane 10's stability, improve node structure's waterproof performance.
The bottom of sheath 9 body sets up pressure disk 91, and pressure disk 91 presses on second coiled material waterproof layer 6, forms to press to hold fixedly second coiled material waterproof layer 6, improves the compactness at first coiled material waterproof layer and second coiled material waterproof layer contact position to waterproof performance has been improved.
In order to further improve the waterproof performance, the annular gap between the gasket 4 and the anchor rod 1 is filled with polyurethane 10,
the horizontal cement-based permeable crystalline waterproof layer 3 can well support the polyurethane 10 in the annular gap, and the stability of a waterproof structure is improved.
