Description
Technical Field
The invention relates to a formwork supporting method, in particular to an end constructional column formwork supporting optimization method.
Background
The packed wall constructional column has the following functions: 1. the shear strength of the wall body is improved; 2. the deformability of the wall and the house is greatly improved; 3. and a restraint system is formed together with the roll beam, so that the generation and development of wall cracks are effectively limited, and the wall body is prevented from collapsing. Thus, the constructional columns directly affect the overall safety performance of the house, and are particularly indispensable for the frame structure infilled wall. At present, when pouring construction is carried out on the filler wall constructional column, the adopted traditional constructional column template generally wraps a plurality of transverse ribs on the outer side of the forming template. The formwork structure of making post that adopts, including three curb plates, three curb plates are installed in the steel reinforcement cage outside, and wherein two blocks of curb plates in positive and negative can adopt split bolt fixed, and the fixed site of the template of side often adopts step tightly, and step tightly can destroy the wall of laying well.
The known forms of formwork construction for pillars therefore suffer from the inconveniences and problems described above.
Disclosure of Invention
The invention aims to provide a safe and reliable end constructional column formwork supporting optimization method.
In order to achieve the purpose, the technical solution of the invention is as follows:
an end constructional column formwork optimization method is characterized by comprising the following steps:
a. when building a wall, pre-burying reinforcing steel bars at positions away from the serrated racking in advance at a plurality of distances;
b. the length of the embedded steel bars is that the wall thickness is increased by 40mm, so that the embedded steel bars extend out of two sides of the wall body by 20mm respectively;
c. the spacing of the embedded steel bars is equal to that of the transverse ridges of the constructional column;
d. when the formwork is erected, the embedded steel bars and the transverse ribs are tightly hooked step by step to fix the side formwork.
The method for optimizing the end constructional column formwork can be further realized by adopting the following technical measures.
The method described above, wherein the distance is 200mm or more.
The method of the preceding, wherein the rebar is a 10mm rebar.
After the technical scheme is adopted, the end constructional column formwork supporting optimization method has the following advantages:
1. the principle is simple and easy to understand, the construction is convenient and reliable, the operation is easy, and the construction quality can be ensured;
2. the wall body can not be damaged, and the construction process is optimized.
Drawings
Fig. 1 is a schematic diagram of the positions of embedded bars according to an embodiment of the present invention;
fig. 2 is a schematic view of a serrated racking portion template arrangement structure according to an embodiment of the present invention.
In the figure: 1 reinforcing steel bar, 2 battens, 3 steps of tightening and 4 templates.
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
Referring to fig. 1-2, fig. 1 is a schematic diagram of positions of embedded steel bars according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a formwork arrangement structure of a serrated racking portion according to an embodiment of the present invention.
According to the optimization method for the end constructional column formwork, when a wall is built, a steel bar 1 with the diameter of 10mm is pre-embedded at a position 20mm away from a serrated racking in advance, the length is the wall thickness plus 40mm (two surfaces of a wall body respectively extend out by 20 mm), and the distance is equal to the transverse ridge of the constructional column. When the formwork is erected, the side formwork 4 is fixed by tightly hooking the embedded steel bars 1 and the transverse ribs by the aid of the step 3 liner battens 2. Meanwhile, when plastering construction is carried out in the later period, the embedded steel bars can be used for hanging steel bar meshes or backing steel bars.
The invention has substantive characteristics and obvious technical progress, and the optimization method of the end constructional column formwork of the invention has the advantages of simple and understandable principle, convenient and reliable construction, easy operation, capability of ensuring construction quality, no damage to the formed wall surface, provision of fulcrum force for fixing the side formwork and provision of fulcrum for plastering and hanging the reinforcing mesh or the backing reinforcing steel.
The end constructional column formwork supporting optimization method is applied to engineering examples, has obvious effect, is consistently recognized by supervision units and construction units, is welcomed by operators, and obtains good economic benefit and social influence.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Accordingly, all equivalents are intended to fall within the scope of the invention, which is defined in the claims.
