Description
Technical Field
The utility model relates to a technical field of template system particularly, relates to a template system that is used for frame post and door window opening wall buttress integral pouring.
Background
In the secondary structure design of the building, when a door and window opening is arranged at the turning part of a filling wall body or a T-shaped wall, a wall buttress is generally arranged to ensure the stability of the wall body and facilitate the installation of a door and window frame. When the door and window wall pillar is close to the frame column and the length of the wall pillar is small, if the wall pillar is constructed by brickwork, the length-fineness ratio of the wall pillar is increased, the influence on a structural load-displacement curve is obvious, the rigidity and the bearing capacity of a component are reduced no matter the component is in an elastic stage or a nonlinear reinforcement stage along with the increase of the length-fineness ratio, and the structure is easy to be unstable, so that potential safety hazards are caused. And the brick masonry can not form staggered joints for construction, and is not in line with the standard requirement, and is difficult to bear the vertical load transmitted by the door and window lintel, so in the actual construction, the brick masonry wall buttress with smaller size is similar to the masonry wall buttress with smaller size, the secondary structure construction is replaced by a cast-in-place concrete wall buttress or a constructional column, the national building standard design drawing sets the requirements of masonry infilled wall structure (12G 614-1) 5.4.3, and when the distance from the end of the infilled wall with the door and window opening to the edge of the door and window opening is less than 240mm, a reinforced concrete door and window frame is suitable to be adopted. However, because the secondary poured wall pile has small structure size, needs to be connected with the frame columns by planting ribs, has complex formwork supporting procedures, is difficult to distribute and vibrate and the like, the construction wastes time and labor, the structure size deviation and the appearance quality are poor, the subsequent plastering and door and window installation construction are directly influenced, and unnecessary scraping and reworking waste is caused.
Through continuous process improvement, for a small wall pile close to a frame column, the most reasonable construction method is to adopt a scheme of formwork support and integral pouring of the wall pile and the frame column, which is favorable for ensuring the integrity and the bearing capacity of the structure, simplifies the construction process, and saves a large amount of turnover materials and working time cost. The structural schematic diagram of the door and window opening wall buttress is shown in figure 1.
In the conventional process on site, during construction of a frame main body structure, most technical measures for optimizing the frame column and the small wall buttress cannot be planned, a scheme of secondary formwork pouring of the wall buttress during construction of a secondary structure is still adopted, or due to the lack of an effective formwork mounting and reinforcing process, a supporting and fixing mode of a special-shaped column formwork formed by combining the frame column and the wall buttress is unreasonable, a formwork system is lack of sufficient strength and stability, adverse factors such as untight abutted seams, insufficient rigidity, difficult fixing and the like generally exist, and in the process of pouring concrete, under the action of lateral pressure of the concrete, the column formwork system is easy to displace or crack, so that quality defects such as deformation and expansion, slurry leakage and slab staggering, slag inclusion and meat biting are caused, the structural quality and the impression effect after forming of components are influenced, and a large amount of chiseling treatment cost is generated.
An effective solution to the problems in the related art has not been proposed yet.
