Description

A New Steel Formwork for Wall Columns

technical field

The utility model relates to a novel wall column steel formwork, which belongs to the technical field of steel formwork construction.

Background technique

A large number of plywood and wooden back corrugated are used as construction formwork in existing building construction. Not only is the size of this formwork difficult to control, but it is prone to problems such as grout leakage and mold explosion during the pouring process, resulting in poor quality of formed wall columns. In addition, The cutting process of plywood and wood cubes is one of the key sources of dust pollution, which pollutes the construction environment, and the number of turnovers of wooden formwork is small, which wastes wood resources and creates a lot of construction waste. The dwindling of forest resources and the irrational use of waste wood templates have brought more and more threats to people's living environment and health. The environmental protection problems brought by the construction industry should arouse people's attention. In addition, plywood is combined with wooden square back. Due to the uneven quality of operators, the phenomenon of random cutting of turnover materials on site is becoming more and more serious. The management of turnover materials is becoming more and more difficult, and the cost pressure is also rising sharply.

In order to save construction costs, some construction units use full steel pipe scaffolding to support the formwork, but the full steel pipe scaffolding needs to be connected by vertical and horizontal horizontal rods to ensure stability, and the setting of horizontal braces and scissor braces will bring inconvenience to construction passages, cumbersome assembly and disassembly, Increase turnover materials, increase costs and other issues.

Utility model content

The purpose of this utility model is to provide a new type of wall column steel formwork with simple structure, convenient construction, reusable, construction cost saving, and standard size, so as to avoid the phenomenon of slurry leakage, mold explosion, etc., and ensure the vertical level of the wall To improve the forming quality of the wall column.

The technical scheme of the utility model: a new type of wall column steel formwork, including a female corner mold, a male corner mold and a large formwork connected to both ends of the female corner mold or the male corner mold. The large template is symmetrically arranged on both sides of the wall column On the outside of the large formwork, there is a large backing board, and a backing plate is set on the big backing board. One end of the tapered rod bolt is threaded with an adjusting nut, and the other end passes through the backing board, the big backing board, and the large backing board on the side of the wall column in turn. After the formwork, pass through the large formwork, large back corrugated and backing plate on the other side of the wall column in turn. A wedge-shaped hole is set at the exit end of the tapered rod bolt, and a wedge-shaped pin is inserted in the wedge-shaped hole. Through the tapered rod bolt, the The large formwork on both sides of the wall column is connected and fixed.

The small end of the tapered rod bolt penetrates from the outside of the wall stud. After the construction is complete, the tapered rod bolt is removed, so that a tapered hole with a large outer end and a small inner end can be left on the wall stud, which is not only convenient Post-blocking, but also to avoid wall seepage.

The cross-section of the female angle mold is a pentagonal structure, the pentagon structure is composed of two symmetrical right-angled sides and a horizontal side, symmetrically opened on the two non-adjacent right-angled sides of the female angle mold Groove and groove, one end of the large formwork is docked with the female angle mold through the groove and groove. Therefore, when installing the formwork, the positioning of the large formwork can be realized through the tongue and groove at both ends of the female corner mold, and the installation accuracy and efficiency of the formwork can be improved.

A supporting block is fixed on the female corner mold by bolts, and the two ends of the supporting block are supported on the large formwork at both ends of the female corner mold, so as to improve the connection strength between the large template and the female corner mold, and avoid grout leakage during pouring.

A group of connecting steel plates are welded from top to bottom on the horizontal side of the female angle mold to improve the overall strength of the female angle mold.

The male angle mold is an integral right-angled steel plate, and a group of reinforcing ribs are welded on the outer wall of the right-angled steel plate.

Due to the adoption of the above technical scheme, the utility model has the advantages that: the large formwork, the female corner mold and the male corner mold of the utility model are all made of stereotyped steel molds, which are not only convenient for construction, can be reused, and save construction costs, Moreover, the standard size is easy for workers to grasp, which can effectively avoid the phenomenon of slurry leakage, mold explosion, etc., ensure the verticality of the wall, and improve the forming quality of the wall column. At the same time, the small end of the tapered rod bolt of the utility model penetrates from the outside of the wall stud. After the construction is complete, the tapered rod bolt is removed. The hole is not only convenient for later sealing, but also prevents water seepage from the wall. Therefore, the formwork of the utility model not only has tight joints, is smooth, does not leak, has a good platform, does not expand the formwork, does not run away from the formwork, and does not deform, and the surface of the wall after the formwork is removed is relatively smooth, and no special treatment is required. The utility model starts from the structural characteristics, fully considers the construction requirements of the structure, meets the quality requirements of the concrete construction, and ensures the safety of the construction, makes the design and manufacture of the steel formwork more in line with the actual construction requirements, and achieves applicable, economical, reasonable and safe construction.
