Description
Technical Field
The utility model relates to a building technical field especially relates to a construction joint waterproof construction.
Background
In the process of constructing the underground concrete wall, a very important criterion is that no gap is left, because the construction gap can influence the stress of the wall structure and bring a new problem that the wall needs to be waterproof. In the actual construction process, under special conditions, construction joints exist on the wall body located underground. The construction joint is a weak link in the waterproof treatment of the whole wall body, the durability and the strength of the whole wall body are directly influenced by the waterproof treatment of the construction joint, and if the treatment is not good, the phenomenon of water leakage or water seepage is caused, so that the whole building is influenced. The existing technology is that the middle part of the concrete wall body is provided with a water stop steel plate to play a role in water prevention, but in the construction of a reverse construction method, a horizontal structure (a beam-slab structure) is constructed firstly, and then a vertical structure (a wall column) is constructed. Under the beam support system, the steel plate water stop belt cannot be buried to prevent water.
Therefore, a waterproof structure for construction joints is needed to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a construction joint waterproof construction can reach better water-proof effects.
To achieve the purpose, the utility model adopts the following technical proposal:
The utility model provides a construction joint waterproof construction, its characterized in that, includes first waterproof coating layer, second waterproof coating layer, waterproof roll material layer, mortar layer and water swelling sealing rod, first waterproof coating layer sets up on the wall surface of concrete wall, waterproof roll material layer sets up first waterproof coating layer is kept away from on the terminal surface of one side of wall surface set up flutedly on the interior wall surface of concrete wall, the construction joint is located tank bottom surface middle part of recess, second waterproof coating layer sets up on the tank bottom terminal surface of recess, the mortar layer is filled in the recess, water swelling sealing rod sets up the middle part of construction joint.
Preferably, the groove is a rectangular groove.
Preferably, the first waterproof coating layer and the second waterproof coating layer are both polyurethane waterproof coatings.
Preferably, the waterproof roll material layer is a polyester-tire waterproof roll material.
The utility model has the advantages that:
the utility model provides a waterproof structure of construction joint, through set gradually first waterproof coating layer and waterproof roll material layer on the outer wall of concrete wall, set up flutedly on the interior wall of concrete wall, set up second waterproof coating layer and mortar layer in the tank bottom of recess, can prevent infiltration or the phenomenon of leaking effectively, set up water-swelling sealing rod at the middle part of construction joint, water-swelling sealing rod can expand by oneself after meeting water, fill and plug up the clearance of construction joint, thereby play and prevent to leak, the effect of infiltration. Through the protection, can play fine waterproof effect to the construction joint.
Drawings
FIG. 1 is a cross-sectional view of a construction joint waterproofing structure of the present invention;
In the figure:
1-a first water-proof coating layer; 2-waterproof roll layer; 3-a second waterproof coating layer; 4-a mortar layer; 5-concrete walls; 6-construction joint; 7-water swelling water stop strip.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements related to the present invention are shown in the drawings.
as shown in fig. 1, the utility model provides a construction joint waterproof construction, include: first waterproof coating layer 1, second waterproof coating layer 3, waterproof roll material layer 2, mortar layer 4 and water swelling sealing rod 7 meet, first waterproof coating layer 1 sets up on the outer wall face of concrete wall 5, waterproof roll material layer 2 sets up on the terminal surface of one side of first waterproof coating layer 1 keeping away from the outer wall face, set up flutedly on the interior wall of concrete wall 5, construction joint 6 is located the tank bottom surface middle part of recess, second waterproof coating layer 3 sets up on the tank bottom terminal surface of recess, mortar layer 4 is filled in the recess, meet water swelling sealing rod 7 and set up the middle part at construction joint 6. Through set gradually first waterproof coating layer 1 and waterproof roll material layer 2 on the outer wall of concrete wall 5, set up flutedly on concrete wall 5's interior wall, set up second waterproof coating layer 3 and mortar layer 4 in the tank bottom of recess, just so can prevent infiltration or the phenomenon of leaking effectively, furtherly, set up water-swelling sealing rod 7 in the middle part of construction joint 6, water-swelling sealing rod 7 can produce the inflation deformation in meeting water, be full of all anomalous surfaces and clearances in the construction joint, thereby play and prevent leaking, the effect of infiltration. Through the protection, can play fine waterproof effect to the construction joint.
Specifically, be the rectangular channel with the recess design, the tank bottom surface of recess parallels with concrete wall 5's side, thereby can scribble well and establish second waterproof coating layer 3, after scribbling and establishing second waterproof coating layer 3, fill mortar layer 4 in the recess again, can reduce the use of mortar through the aforesaid setting, play the effect of waterproof seepage simultaneously, specifically, keep away from the terminal surface of recess tank bottom and concrete wall 5's interior wall parallel and level with mortar layer 4, thereby guarantee the plane degree of wall, it is convenient to construct for follow-up fitment.
specifically, the first waterproof coating layer 1 and the second waterproof coating layer 3 are both polyurethane waterproof coatings, and the coatings have the advantages of high strength, large elongation and good water resistance. The waterproof roll layer 2 is made of polyester tire waterproof roll with good extensibility, long service life and simple and convenient construction. The water-swelling sealing rod 7 is made of rubber, but the waterproof effect is better than that of a common rubber material, and the water-swelling sealing rod can expand and deform 2-3 times when meeting water and can generate huge contact pressure with a construction joint, so that leakage is thoroughly prevented.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
