Description

A formwork for pouring structural columns based on standard joint combinations

technical field

The invention relates to a building construction tool, in particular to a template for pouring structural columns based on standard joint combinations.

Background technique

With the continuous development of building construction technology, the requirements for the quality of wall masonry molding are getting higher and higher. In the construction of structural columns in existing construction projects, the wooden formwork is usually pre-closed on both sides of the wall to form a pouring space for the structural columns, and then concrete is artificially poured from the opening left on the upper end of the structural column formwork. The construction of the wall structural columns uses Once the formwork is supported to the top, the concrete pouring is completed at one time. Due to the small space of the structural column and the dense steel bars, the above method is used for construction. The concrete pouring and vibration of the middle and lower parts of the structural column are inconvenient, which easily leads to poor appearance and physical quality of the formed concrete, and because the concrete at the pouring port cannot With effective vibration, no effective connection can be produced between the top of the structural column and the main structure, resulting in a decrease in the seismic performance of the building and affecting safety. During the operation, the installation and removal of the formwork is troublesome, the turnover of materials is low, and the waste of manpower and material resources is serious.

The patent with application number 201510272937.9 discloses a construction column formwork, which is also based on the idea of standardized sections, including the front formwork and the back formwork. Although the construction efficiency can be improved, the height of the back formwork and the front formwork needs to match, and the front formwork It is required to be synchronized with the fixing method of the back formwork, which increases the operating time of the formwork fixing link; in addition, due to the structural requirements of the front pouring formwork, the opening position of the pouring port is lower, which may easily lead to the ineffective pouring of the concrete at the upper end of the structural column.

The patent application number 201110285923.2 discloses a segmented construction method of structural columns in masonry engineering. It is necessary to first determine the technical parameters according to the structural columns, then process and manufacture formwork, and then install and pour concrete in segments. This method is relatively cumbersome, and the reserved opening needs to be taken into account when building the wall, and the cost of time and material resources is relatively high. It is generally not high, and it is difficult to guarantee the accuracy of operation.

As shown in Figure 9, the closed gate 308 and the funnel gate 402 are opened, and the blanking hopper 401 is installed, and the concrete is conveyed through the blanking hopper 401 and Insert a vibrating rod from the opening to vibrate until the concrete surface is higher than the top of the structural column, close the closing gate 308 and the funnel gate 402 in sequence, disassemble the feeding funnel 401, and perform concrete sealing and curing. The excess concrete in the feeding hopper 401 is recycled, and the feeding hopper 401 can be recycled. Thus, the pouring quality of the structural column is ensured, and the secondary treatment of the top concrete is not required, which greatly improves the construction work efficiency.

The described embodiment is a preferred implementation of the present invention, but the present invention is not limited to the above-mentioned implementation, without departing from the essence of the present invention, any obvious improvement, replacement or modification that those skilled in the art can make Modifications all belong to the protection scope of the present invention.
