The implementation steps are as follows:
designing a bare concrete template:
1) the design is deepened to the clear water concrete engineering comprehensively before the template design, properly solves the key problem that the veneer effect is influenced if: open joints, cicada joints, split bolt holes, construction joints, post-cast strip and the like.
2) Selecting a template system: selecting a template system which can meet the appearance quality requirement of the fair-faced concrete and has enough strength, rigidity and stability; the template system requires tight splicing, accurate specification and size, is convenient to assemble and disassemble, and can ensure the requirement of turnover use times.
3) Template blocking principle: in the allowable range of the hoisting load, the blocks are designed according to the distribution of cicada seams and open seams, and the forming, the integration, the modulization and the generalization of the blocks are considered.
4) Panel segmentation principle: the cicada seams and the open seams of the template are divided according to the positions, and the horizontal intersection and the vertical perpendicularity of the cicada seams and the open seams must be ensured.
5) Arranging split bolt holes: the decorative effect of regularity and symmetry should be achieved, and the stress requirement should be met.
6) And (3) node processing: and reasonably designing template nodes according to engineering design requirements and engineering characteristics.
Preparing materials:
(1) arc steel pipe 1 bent to corresponding radian
(2) Cutting the split bolt bar 2, length L being wall thickness-single horn head length
(3) Assembling the horn head 3 and the bolt rod 4, and treating the horn head by using an isolating agent
(4) The bamboo glue template 6 is perforated according to the designed position, and the aperture is 2-3mm larger than the diameter of the bolt rod 4.
The construction process flow comprises the following steps:
(1) popping an outer sideline of an arc-shaped steel pipe on the surface of the bottom plate 16 of the inner wall of the structure pool;
(2) building double rows of inner scaffold frames 7 and double rows of outer scaffold frames 8;
(3) using a hammer ball for correction, and fixing the arc-shaped steel pipe 9 in the uppermost layer;
(4) fixing the lower arc-shaped steel pipe 10 according to the suspension wire of the arc-shaped steel pipe 9 at the uppermost layer, and thinly discharging;
(5) placing an inner membrane bamboo glue template of the bamboo glue template 6; the outer membrane bamboo glue template is arranged at the other end of the split water-stop bolt rod;
(6) the vertical steel pipes 17 are placed through split bolts with horn heads at intervals of 15 cm; and the inner arc steel pipe 9 is encrypted according to the position of the template hole;
(7) standing an outer bamboo glue template 6;
(8) vertically placing the outer vertical steel pipes 17 at intervals of 15 cm;
(9) an outer arc steel pipe 9 is added and an outer cap of the outer opposite pulling water bolt rod 2 is fastened.
The construction method and the key points are as follows:
(1) the advanced calculation is needed before the snapping line of the surface of the bottom plate of the structure, and the radius of the structure is as follows:
r＝R-δ-Φ
r: radius of elastic thread
R is radius of inner wall of the tank
Phi: the diameter of the vertically placed steel pipe is 48mm
δ: template thickness (12-18mm)
The line must be rigorously rechecked. Since both the radius and arc of the wall are controlled by this line.
(2) The system has good template strength, rigidity and stability, but the inclined struts 13 are required to be added to ensure the integral stability and perpendicularity of the template during concrete pouring, and the reinforcing steel bar heads 14 are preferably reserved at corresponding positions during bottom plate pouring to reinforce the inclined struts 13. Since the inner scaffolding 7 is required to fix the uppermost arc-shaped steel pipe 9, the specification requirements are strictly fulfilled when erecting the scaffold.
(3) The arc-shaped steel pipe 9 is erected on the template, and the arc-shaped steel pipe is mechanically bent by using a pipe bending machine, so that the radian of the mechanical bent pipe is accurate, the uniform speed can be ensured during bending, and the consistency can be ensured after a small amount of backfill is carried out after the steel pipe is bent. The use of hammer ball correction to fix the uppermost inner arc steel pipe 9 is a key step in technical control in construction operation. The horizontal outer side line of the arc-shaped steel pipe 9 and the elastic line of the inner wall plate 16 of the bottom water pool are required to be at the same horizontal position.
(4) The quantity of rare row arc steel pipe 9 should have 1 ~ 2 for every layer of bamboo glued membrane 6, should transversely put when bamboo glued membrane 6 is assembled, and its advantage has two: firstly, the bamboo glue template has certain rigidity, when the bamboo glue template is transversely placed, the arc length of a single template is longer, and the structural size and the radian are easy to control. ② the usage amount of the square timber is reduced. When the steel pipe 17 is vertically placed on the inner mold, the theoretical contact surface of the bamboo glue template and the vertical steel pipe is a line, so that the vertical joint of the template must use a square method, the thickness of all used vertical square wood is consistent and is preferably 1-2 mm larger than the outer diameter of the steel pipe, and in order to prevent the bamboo glue mold from being embedded into the concrete, the square wood placed on the inner wall is preferably dense and is generally made of 5 multiplied by 5cm square wood. When the arc steel pipe 9 is encrypted, the joints are staggered by 25%. The vertical steel pipes 9 can be spliced, and the length of the square wood is not limited.
(5) And (3) carrying out treatment of an isolating agent on the pre-embedded horn head 3 of the pull water bolt 2 before installation so as to facilitate the dismantling of the horn head 3. According to multiple experiments in construction, industrial wax is preferably mixed with diesel oil to be melted, and the horn head is dipped to form a layer of isolating film on the surface of the horn head. The plugging of the horn hole is carried out by mixing the concrete with the portland cement with the same label and the acrylic latex, stirring to a semi-dry state, compacting into the inner surface of the hole, and leveling.
The arc-shaped water pool formwork supporting system of the bamboo plywood not only effectively controls the building cost, but also is simple in formwork supporting operation, and can perfectly meet the requirements of the appearance, the impermeability and the like of an arc-shaped fair-faced concrete wall.
