Description
TECHNICAL FIELD
[0001] The utility model relates to fair-faced concrete and fair-faced formwork construction technical field, concretely is a kind of improved fair-faced formwork system lower reinforcing structure. BACKGROUND
[0002] Fair-faced formwork is a kind of building formwork with high-quality wood as base material, which is made by phenolic resin impregnation and high-temperature hot pressing process, and is named because the surface of the cast concrete is smooth and can be directly decorated. Fair-faced formwork is suitable for large infrastructure: dam, tunnel, overpass and arch bridge bridge engineering, high-rise building: shear wall, vertical wallboard and beam-column structure; industrial scene: workshop, workshop and other buildings with high requirements for concrete surface quality. In the existing construction technology, the formwork is directly placed on the base plane, which leads to the phenomenon of rotten roots, wet water and slurry leakage at the bottom of the fair-faced wall. UTILITARIAN CONTENT
[0003] In view of the deficiencies of the prior art, the utility model provides an improved fair-faced formwork system lower reinforcing structure, which solves the problems raised in the above background art.
[0004] To achieve the above purpose, the utility model realizes the following technical scheme: an improved fair-faced formwork system lower reinforcing structure, comprising a base layer, a fair-faced formwork structure is arranged on the top of the base layer, a vertical direction groove is formed on the top of the base layer below the fair-faced formwork structure, a horizontal direction groove is formed on the top of the base layer outside the fair-faced formwork structure, a plurality of water stop sealing strips are placed at the bottom of the vertical direction groove inner cavity, and a sealing elastic structure adhesive is filled in the horizontal direction groove inside and outside the fair-faced formwork structure.
[0005] Preferably, the number of water stop sealing strips is two layers.
[0006] Preferably, the fair-faced formwork structure is above the water stop sealing strips.
[0007] Preferably, the vertical direction groove is located inside the base layer and 20mm-30mm below the fair-faced formwork structure.
[0008] Preferably, the horizontal direction groove is located outside the fair-faced formwork structure and 5mm above the vertical direction groove.
[0009] The utility model provides an improved fair-faced formwork system lower reinforcing structure, which has the following beneficial effects:
[0010] The improved clean water formwork system lower reinforcing structure, by setting vertical direction groove, horizontal direction groove, sealing elastic structural glue and water stop sealing strip, compared with the prior art, can reduce the phenomenon of rotten root, wet water, slurry leakage and dog hole of the clean water wall bottom, and ensure the uniform and complete effect of the clean water concrete lower mouth finish. BRIEF DESCRIPTION OF DRAWINGS
[0011] Fig. 1 It is a construction structure schematic view of the utility model;
[0012] Fig. 2 It is a vertical direction groove and horizontal direction groove structure schematic view of the utility model base.
[0013] In the figure: 1, base; 2, vertical direction groove; 3, horizontal direction groove; 4, sealing elastic structural glue; 5, clean water formwork structure; 6, water stop sealing strip. DETAILED DESCRIPTION
[0014] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0015] Please refer to Figs. 1-2 The utility model provides a technical scheme: an improved clean water formwork system lower reinforcing structure, including base layer 1, the top of base layer 1 is provided with clean water formwork structure 5, the top of base layer 1 and below clean water formwork structure 5 are provided with vertical direction groove 2, the top of base layer 1 and outside clean water formwork structure 5 are provided with horizontal direction groove 3, the bottom of vertical direction groove 2 inner chamber is placed with several layers of water stop sealing strip 6, and the inside of horizontal direction groove 3 and outside clean water formwork structure 5 are filled with sealing elastic structural glue 4.
[0016] The number of water stop sealing strips 6 is two layers, by being provided with two layers of water stop sealing strips 6, so as to prevent the occurrence of water leakage and slurry leakage.
[0017] Clean water formwork structure 5 is above water stop sealing strip 6.
[0018] Vertical direction groove 2 is inside base layer 1 and below clean water formwork structure 5 20mm-30mm.
[0019] Horizontal direction groove 3 is outside clean water formwork structure 5 and above vertical direction groove 2 5mm.
[0020] In summary, the improved clean water formwork system lower reinforcing structure, when in use, on the top of the base layer 1, according to the structure size of the clean water formwork structure 5, a vertical recess 2 of 20mm-30mm in depth is reserved in advance on the top of the base layer 1 in the vertical direction on the basis of the original construction, and a horizontal recess 3 of 5mm in width is reserved on each side of the horizontal size of the clean water formwork structure 5, before the formwork is laid in the vertical direction of the clean water formwork structure 5, two layers of water and slurry leakage prevention water stop sealing strips 6 are laid in the vertical recess 2 of 20mm-30mm in depth, then the vertical clean water formwork structure 5 is erected on the water stop sealing strips 6, and the horizontal and vertical clean water formwork structure 5 joint is filled with the sealing elastic structure glue 4 inside the horizontal recess 3, after the reinforcing system is completely reinforced for 2 days, the clean water concrete pouring construction work can be carried out.
[0021] The above is only the preferred specific implementation method of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
