How to deal with the sticky wall column of the formwork

Generally, it is used to pry with a crowbar, but some of them are fused with concrete for a long time, and finally need to be chiseled down. Otherwise, it will not be possible to continue the decoration unevenly.

This one still has to be removed! If you don't dismantle it, you will have unnecessary trouble when the template rots! In that case, it will be hard to deal with it again!

Shake with a hammer. He'll come down.

Add diagonal brace and horizontal brace (at the bottom, connect with the diagonal brace with fasteners, do not top the sweeping rod of the template, otherwise the mold explosion will affect the entire support). If it is a civil air defense wall, remember not to wear a pair of screws.

Diagonal braces and tension bolts were added.

Walls and columns are not used for demoulding. Roof plates, beams, etc. with vertical support should be applied.

Application form for removal of wall column formwork.

Yes, in general, the removal of the wall column formwork should pay a formwork application form before the formwork removal inspection batch.

Just the wall and column are not used to remove the mold. Only those with vertical supports such as roofs and beams must apply.

The next day you can, of course, before dismantling to see if it has hardened.

1.wall, generally about 12 hours.

2.The top plate generally takes 28 days, or the strength should reach 75%.

3.Cantilevered elements, such as balconies, should be 100% strong.

4.Removal of side formwork of walls, columns and beams: The concrete strength should ensure that its surface and edges and corners are not damaged due to the removal of the formwork, and the general strength can only be dismantled. The demoulding time should be controlled according to the strength grade of the concrete, the ambient temperature or by curing the test block under the same conditions.

5.Beam, slab bottom mold removal: beam, slab span within 2m, concrete strength reaches 50 of the design strength; In the range of 2-8 meters, its strength reaches 75 of the design strength; Concrete greater than 8m must reach 100 of the design strength before it can be removed.

6.Formwork removal of cantilever members: Regardless of the length of the span, it is required that the concrete must reach 100% of its design strength before it can be dismantled.

7.The code stipulates that for cantilever beams and slabs with a span of less than 2m, the concrete demoulding strength should be greater than or equal to 70%; For cantilever beams and slabs with a span of more than 2m, the demoulding strength of concrete is 100%.

As long as the strength is reached, the mold can be removed.

If there is no special requirement, the time to dismantle the wall column side formwork is generally that the concrete reaches 1MPa strength, and the removal of the formwork will not lack edges and corners, and the side formwork can be removed. The purpose of the so-called 1MPa strength is also to ensure that there is no lack of edges and corners, in order to have a data regulation.

However, there are waterproof requirements, especially for basement exterior walls, which cannot be removed in this way. Generally, the exterior wall of the basement requires mold maintenance, and even 14 days to prevent the basement exterior wall from cracking.

No admixtures? The slump is too big! For the wall column formwork, its surface and edges and corners can only be removed if they are not damaged by removing the formwork, and you estimate that the concrete is about the same for two or three days, but what grade of cement do you use, can it reach C30?

GB50204-2002 "Code for Acceptance of Construction Quality of Concrete Structure Engineering" DU

It only restricts the concrete rights of the components when the bottom mold of the plate, beam, arch, shell and cantilever structure is removed.

The strength that must be achieved. There is no bottom mold in the column and shear wall, and the lap counter to the side mold turnover of the cast-in-place construction process is not very urgent, and it is not as good as the sliding membrane construction. As long as it can be ensured that there is no lack of edges and corners after demolition, how many days to reach are mastered, and the specification only requires appearance defects in the cast-in-place component sub-item, and does not specify the time.

If the temperature is high, it will be earlier.

To put it simply: you guys.

These are all theoretical statements, and there are few real versions that make test blocks in order to remove the template. Under normal temperature conditions, it can be done 24 hours after the completion of watering. If in the winter when the temperature is low, it is difficult to say accurately, generally after 50 72 hours can be removed, but it must be guaranteed not to damage the concrete, if it is a pool, it is necessary to ensure that the water-stopping screw is not disturbed.

Shear walls, columns demoulding time copy should be considered concrete.

Its own gravity and the flute do not fall off after dismantling, as well as the height of the column. The general residential concrete shear walls and columns can meet the basic requirements. The specific demoulding time is determined according to the outdoor day and night temperature and the marking of the concrete. It is not a general judgment based on the number of days.

The shear wall column needs to be dismantled by the formwork inspection batch. The shear wall column is not a separate component, and the concrete of the wall column is the concrete of the wall, so the shear wall template removal inspection batch includes the edge column of the wall.

Shear wall is also known as wind-resistant wall or seismic wall, structural wall. Walls in houses or structures that are mainly subjected to horizontal and vertical loads (gravity) caused by wind loads or ** actions to prevent structural shear failure. It is divided into plane shear wall and cylinder shear wall.

Plane shear walls are used in reinforced concrete frame structures, rising plate structures, and beamless floor systems.

1. The formwork calculates the contact area with the concrete 2, and the concrete calculates the cross-sectional area multiplied by the height. The problem to pay attention to is to be careful, do not omit the same house in any decimals, you will have ten results if you calculate ten times, this is normal.

Hello, even if the annual area of the template is used. It is generally used for carpentry to calculate money.

Calculated according to the size of the drawing.

The column defaults to buckle the beam head, the wall should be set, and the engineering setting calculation settings wall 3 wall, insulation wall and non-parallel beam, and the connecting beam select 0 buckle cross type intersection beam and beam head.

The default deduction relationship is the column and beam board.

Generally, it is OK to follow the default.
