Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] refer to figure 1 As shown, in Example 1, a one-time forming construction method of fair-faced concrete for gate pier includes (1) steel formwork design:

[0029] a. Before the design of steel formwork, one should be fully familiar with the structural design drawings related to the formwork, clarify the structural quality requirements, understand the construction organization design of the project related to the erection of supports and the layout of vertical transportation equipment, etc. Preliminary determination of the maximum size and modulus of the template according to the storage and other conditions;

[0030] b. The design of steel formwork should follow the basic requirements of standardization and generalization, and at the same time, special design should be carried out for special structural parts such as gate corbels, gate slots, cantilevered platf...

Abstract

The invention is suitable for gate piers, dam bodies and wall boards of hydraulic engineering buildings and other concrete engineering having high quality requirements of exposed surfaces, and provides a gate-pier fair-faced concrete one-off forming construction method. The gate-pier fair-faced concrete one-off forming construction method comprises the steps that (1) a steel formwork is designed; (2) the steel formwork is manufactured; (3) staking out in survey is conducted; (4) steel bars are manufactured and installed; (5) the steel formwork is installed and corrected; (6) concrete pouring is performed; (7) the steel formwork is removed; (8) the concrete is maintained. According to the gate-pier fair-faced concrete one-off forming construction method, a gate pier formed in a poured mode has the flat and smooth surface, soft and smooth curved surface arc and plane connection lines and straight edges and corners, the surface of the concrete has consistent color and luster, and the common quality problems of flow marks, joint dislocation and the like of concrete of conventional hydraulic engineering buildings are solved.

Description

[0001] technical field [0002] This construction method is suitable for concrete projects with higher quality requirements on the exposed surfaces such as gate piers, dam bodies, and wall panels of hydraulic structures. Background technique [0003] With the development of the economy and the improvement of the construction technology level, people are increasingly pursuing the harmony and beauty of the building and the environment, and put forward higher requirements for the appearance quality of the project. Fair-faced concrete, also known as decorative concrete, began to be popularized and applied in domestic construction projects in the 1990s. Fair-faced concrete is used more and more because of its characteristics such as one-time molding, no chiseling repair, no need for decoration, smooth appearance, simple and natural. [0004] Concrete structures such as gates and dams of traditional water conservancy projects basically do not use external decoration such as plast...
