Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the basement outer wall and bottom plate corner waterproof node is formed by pouring concrete on the bottom plate 1 and the outer wall 2 of the basement, and a vertical corner is formed between the two.
A heat preservation layer I3, an additional cement layer I4, a waterproof layer I5 and an additional waterproof layer I6 are sequentially laid below the bottom plate 1 from bottom to top, and a brick mould 7 is vertically supported outside the bottom plate 1. The waterproof layer I5 completely covers the bottom surface of the bottom plate 1, the end part of the waterproof layer I extends upwards to the outer wall 2 along the inner side of the brick moulding bed 7, and the height of the part, covering the outer wall 2, of the waterproof layer I5 is 250 mm. The additional waterproof layer one 6 partially covers the bottom surface of the soleplate 1, the length of the part is 250mm, and the end part of the additional waterproof layer one 6 extends upwards to the corner along the outer side of the soleplate 1. The first waterproof layer 5 and the first additional waterproof layer 6 both adopt SBS modified waterproof rolls. The top surface of the brick moulding bed 7 is 200mm higher than the top surface of the bottom plate 1, an additional cement layer II 8 is arranged on the outer side of the brick moulding bed 7, and the additional cement layer II 8 extends to a corner from the brick moulding bed 7.
When the bottom plate 1 is built, a brick wall, namely a brick bed die 7, is built along the periphery of a pit serving as a basement space and serves as a template for subsequent concrete pouring. And then, fully paving the waterproof layer I5 on the whole bottom surface, and turning the extending part of the waterproof layer I5 to be above the brick moulding bed 7. Then, an additional waterproof layer I6 is laid, and the extending part is also turned over above the brick moulding bed 7. After the two waterproof processes are finished, concrete is poured to form the bottom plate 1.
And a second waterproof layer 9, a second additional waterproof layer 10, a second heat-insulating layer 11 and a fine aggregate concrete protective layer 12 are sequentially arranged on the outer side of the outer wall 2 from inside to outside, and the bottom of the fine aggregate concrete protective layer 12 is connected with a second additional cement layer 8. The waterproof layer II 9 and the additional waterproof layer II 10 also adopt SBS modified waterproof coiled materials.
In the actual construction process, the concrete amount is large, and the concrete can not be poured at one time, so that a horizontal construction joint 13 is reserved in the outer wall 2. As shown in fig. 2, the construction joint 13 is located on the wall 500mm above the surface of the bottom plate 1, and the lower part is the cast-in-place concrete 14 and the upper part is the cast-in-place concrete 15. Since water easily permeates into the construction joint 13, a steel plate waterstop 14 with a thickness of 3mm and a width of 300mm is vertically buried in the middle of the wall body of the construction joint 13. The upper and lower both ends of steel sheet waterstop 14 form the hem, and the hem is towards upstream face one side, can effectively prevent the seepage. The steel plate water stop 14 is continuously arranged along the construction joint 13 in a circle-to-circle mode and is connected in a lap joint mode, two sides of the lap joint of the two steel plates are fully welded when the steel plates are lengthened, and the lap joint length is not less than 50 mm.
The utility model is suitable for a there is waterproof way bottom plate lower part, and the suggestion adopts brick wall + to plaster as bottom plate tip template, pastes waterproof additional layer and waterproof layer on the brick mould then pours bottom plate concrete before pouring the bottom plate concrete, notes the protection to the waterproof layer when pouring the bottom plate concrete. Finished product protection measures must be made on the waterproof layer on the brick moulding bed, and when the waterproof layer on the top of the brick moulding bed is used for subsequent waterproof layer construction, the temporary protection is removed, and the waterproof layer is turned over and attached to the bottom plate surface.
When the basement outer wall construction joint is under construction, attention needs to be paid to: the waterproof concrete of the outer wall should be continuously poured, and construction joints are remained as few as possible. When the construction joint is reserved, the horizontal construction joint of the wall body should not be reserved at the position with the maximum shearing force and bending moment or the joint of the bottom plate and the side wall, and should be reserved on the wall body 500mm higher than the surface of the bottom plate. When the wall body is provided with the reserved hole, the distance between the construction joint and the edge of the hole is not less than 300 mm. And burying a steel plate water stop at the construction joint. The vertical seam is provided with a steel plate net for blocking concrete, and the steel plate net is connected with a steel plate water stop belt in a welding mode. Before concrete is continuously poured into the construction joint, surface laitance and sundries at the joint are cleaned, and attachments on the surface of the steel bar are cleaned.
The construction steps of the basement exterior wall are as follows:
1. pre-embedding a steel plate water stop belt/a steel plate net: when a construction joint needs to be arranged, a steel plate waterstop with the thickness of 3mm and the width of 300mm is arranged in the middle of a construction joint wall body before concrete pouring. When the steel plates are lengthened, the lap joint of the two steel plates must be fully welded, and meanwhile, the U-shaped opening of each steel plate faces to the side facing the water. The vertical seam is provided with a dense mesh steel plate net with certain strength to prevent concrete loss, and the steel plate net is welded with the steel plate water stop belt and is firmly fixed.
2. Cleaning a construction joint: before the post-cast concrete wall form is assembled, the laitance, impurities and attachments on the surfaces of the reinforcing steel bars on the surface of the original concrete are cleaned, so that the construction joint is kept in a wet state before casting.
3. Template supporting: sealing is carried out between the template and the concrete of the first-poured wall body by using a sealing belt to prevent slurry leakage.
4. Post-pouring concrete: when the concrete is poured later, the vibration at the construction joint is noticed to ensure the compactness of the concrete at the joint. The time for removing the outer wall is not suitable to be too early, and watering maintenance with a mold can be adopted. After the template is removed, coverings such as gunny bags or straw curtains can be hung on the two sides of the wall for water spraying maintenance, and the maintenance time is not less than 14 d.
5. Waterproof additional layer: and after the surface defect treatment and the screw hole sealing treatment of the wall body, constructing a waterproof additional layer, wherein the width of the waterproof additional layer on two sides of the construction joint is not less than 250 mm. The waterproof additional layer is made of the same material as the waterproof layer.
