The role of brick fetal membrane, what is brick fetal membrane?

The brick tire mold is generally used for the side wall of the basement floor, because it is external waterproof, it must be in the cushion.

Do waterproofing, and waterproofing should be extended to the brick tire mold, so that after pouring concrete later, waterproofing can be turned up to the concrete wall of the side wall, if the side wall of the bottom plate is used with a template, can not do waterproofing, so the method of using bricks to make a template, in addition, in some places where the template can not be removed or it is difficult to dismantle after pouring concrete, there is also a method of using bricks to replace the general template.

Yes, but it is better to use bricks for construction, and the cost is slightly lower; C20 fine stone concrete with a design thickness of 4cm can also be used to cast the formwork, and the cost of molding with concrete is high and the time is long.

In most cases, it is not poured directly on the soil. To give you a simple example: if you compare concrete to glass and earth to cotton, what will happen if you stand on glass?

Does the glass break? Because concrete is rigid and soil is flexible, the deformation of flexible objects is greater after compression, and the deformation of rigid objects is smaller and easy to break after being subjected to reaction force.

Brick fetal membrane refers to the replacement of formwork by brick masonry.

It is widely used in underground structures as an outboard formwork.

such as underground diaphragm walls.

Cast-in-place wall base, column base.

Its advantages are high strength (not suitable for running mold and expanding mold), no need to take it out after construction, enhance strength and play a certain protective role.

It's like a permanent basic template that doesn't need to be dismantled.

Brick fetal membrane refers to the use of bricks to make a surface suitable for a certain shape, specification of the surface of the mold. For example, the beam formwork in the basement "high slab" is replaced by a brick membrane.

Brick tire mold:In fact, there are many projects in use now, most of them are used in the foundation beam, when the side mold of the foundation beam is inconvenient to dismantle, the brick side mold is used, and the inner wall of the side mold is required to be painted, so there is no problem of leakage. Another advantage of the brick side mold is that it is used on the uneven foundation of the rock foundation after blasting.

The brick side mold is generally used for the side wall of the basement bottom plate, because it is external waterproofing, it must be waterproof on the cushion, and the waterproofing should be extended to the brick side formwork, so that after pouring the concrete in the future, the waterproof can be turned up to the side wall concrete wall.

The brick fetal membrane plays a protective and waterproof role.

Brick tire mold is used for basement bottom plate side wall, because it is external waterproof, must be waterproof on the cushion, and waterproof should be extended to the brick tire mold, so that after pouring concrete, waterproof can be turned up to the side wall concrete wall, if the bottom plate side wall is used template, can not do waterproofing, so adopt the method of using brick to make template, after some pouring concrete, template can not be removed, also have the method of adopting brick to replace the general template.

Brick fetal membranes are generally used in these three scenarios:

1. The bottom side of the basement, this part is usually external waterproof, which needs to be waterproofed on the basis of the cushion, and the waterproofing must be extended to the brick fetal membrane, which is used for the concrete after pouring, and the waterproofing can be turned up to the side of the concrete wall.

2. When the concrete is poured, the position that cannot be removed or is difficult to demolish is also constructed with brick membrane.

3. It is used in the rock base layer to blast the uneven structure of the foundation surface.

Kiss! Hello, happy to answer your <>

1. When measuring and pay-off, the axis, elevation, and the distance between the inner wall of the brick fetal membrane should meet the requirements of the design and specifications, and the next process construction can only be carried out after the acceptance of the professional supervision project. 2. Requirements for brick fetal membrane masonry materials: The strength of standard bricks shall not be lower than and shall comply with the specifications and product standards.

In order to ensure the quality of brick membrane construction, the thickness of the brick membrane should be 240mm, and the masonry method should be adopted, and the fullness of horizontal mortar mortar should be greater than 80%, and the corners need to be masonry at the same time. 4. When the outer edge of the brick fetal membrane is within 1m of the distance from the foundation pit wall, 2:8 ash is used to backfill the top surface of the brick fetal membrane, and at the same time, it should be layered and tamped, and the layered thickness should be 200-250mm, and the compaction coefficient shall not be less than that in the process of ramming and filling the ash, the brick fetal membrane shall not be cracked and deformed.

6. The inner side and top surface of the brick fetal membrane should be plastered with 1:2 cement mortar, with a thickness of 20mm, which is divided into two lives, first the plastering thickness is 12mm, and then the plastering thickness is 8mm, the surface should be compacted and trowel, and all the yin and yang corners are wiped with a radius of 20mm arc. 7. The paving of the waterproof membrane is a detailed construction plan.

Hope mine can help you <>

2. The engineering quantity of the brick fetal membrane is selected among the components: ztmtj (brick fetal membrane volume);

Question 3: How to manually calculate the engineering quantity of the brick fetal film in the foundation A cubic brick tire mold requires a square mortar.

It can also be calculated according to the square, 10 square brick tire mold, the appearance of three-bucket mortar.

Question 4: How to calculate the working surface when the foundation beam is constructed with brick tire mold? 1.The bricklaying here is used as a formwork, not as a foundation.

2.The masonry brick mold and the masonry foundation wall are not the same, and the masonry foundation wall needs a certain working surface, in order to ensure the masonry engineering quality of the masonry project, and the brick tire mold as a template is only a construction measure, and the construction unit needs to solve the problem of how to ensure the construction quality by itself.

Question 5: How to calculate the engineering quantity of the brick tire membrane, and which part of the quota 1, the engineering quantity of the brick tire mold is calculated according to the masonry volume, 2, the engineering quantity of the brick tire mold = length * height * thickness, 3, the set of sporadic brick masonry quota subheading.

If you can't figure it out yourself, or don't have time to calculate, it is recommended to find a substitute, depending on the situation, the cost varies.

1. Other methods.

2. You can search for budget cost units on the sales network, and some units do better.

3. You can go to a third-party platform to entrust others to do it, pay attention to anti-fraud on the platform, you can find a unit, or you can find a person to do it.

Second, pay attention.

1. In principle, errors are not allowed in the calculation of engineering quantities, and I hope that the engineering quantity will not be calculated with a fluke attitude;

2. The calculation of the engineering quantity needs to be careful, and the calculation of the engineering quantity of the land defense should be concentrated;

3. There are many ways to calculate the engineering quantity, as long as it suits you, but there is only one rule, which should be calculated in strict accordance with the rules.

Question 6: How to calculate the engineering quantity of brick tire mold There is a standard, and everything is based on the wife's standard.

Question 7: How to calculate the amount of brick fetal membrane, which method is simpler? Compare meters, high meters, find the calculation formula according to the real calculation, set of sporadic masonry.

Question 8: How to calculate the brick tire mold 10 points The actual amount of masonry (length * width * height), if there is plastering, the plastering should also be calculated (squared).

Question 9: How to calculate the engineering quantity of the brick fetal membrane in the graphic calculation Glodon When building the foundation, select the brick fetal membrane in the attribute formwork, and then enter the thickness of the brick fetal membrane.

In the summary calculation, the software automatically calculates the amount of brick fetal membrane.

The brick mold is generally shaped on the side, so it needs to be masonry and painting, and the brick mold only replaces the wooden mold and cannot be reused for masonry. However, at the bottom of the foundation beam, it is often called a brick tire mold. The brick floor mold is generally used to deal with the water-bearing soft foundation, basically without masonry, and the powder surface can be dried after paving.

The brick tire mold is made of standard bricks into a template, and after a certain strength, the concrete pouring work is carried out; The formwork itself is not an integral part of the project entity, and can only be regarded as a measure in construction, and the cost is included in the entity fee; The brick tire mold is generally used for the part of the basement exterior wall that is waterproof or the formwork is not easy to remove, and the size and strength must meet the design requirements after being built.

Uses: 1. The brick mold is paved with bricks on the ground, and the concrete components are poured on it, which is equivalent to the ground formwork.

Second, the use of brick tire mold:

1. The brick tire mold is generally used for the side wall of the basement bottom plate, because it is external waterproof, it must be waterproof on the cushion, and the waterproofing should be extended to the brick tire mold, so that after pouring the concrete, the waterproof can be turned up to the side wall concrete wall, if the bottom plate side wall is used as a template, it cannot be waterproofed, so the method of using bricks to make a template is adopted, and in some places where the template can not be removed or the removal is very difficult after pouring concrete, there is also a cavity method that uses bricks to replace the general template.

In fact, the brick tire mold is to build brick walls of different thicknesses, so the brick tire mold should be distinguished according to the mortar mark used, and the thickness of the brick tire mold should be applied to the quota of the corresponding brick foundation in the quota.

There have been many projects in use of brick tire mold, most of them are buried in the foundation beam, when the side membrane of the foundation beam is inconvenient to remove the brick tire mold, the inner wall of the brick tire mold is required to be painted, so there is no problem of leakage of slurry.

2. After the construction of concrete, the formwork cannot be dismantled or the structural parts that are difficult to dismantle are also used to replace the general formwork.

3. On the rock foundation, the uneven foundation after blasting.

Difference: The brick mulch film should not be poured with cement and should not be waterproof. The brick tire mold needs to be poured with cement and waterproof.

The brick tire mold is made of standard bricks into a template, and after a certain strength, the concrete pouring work is carried out;

The formwork itself is not a part of the project entity, and can only be regarded as a measure in construction, and the cost is included in the entity fee; The brick tire mold is generally used for the part of the basement exterior wall that is waterproof or the formwork is not easy to remove, and the size and strength must meet the design requirements after being built.

The brick tire mold is generally used for the side wall of the basement template, because it is external waterproofing, it needs to be waterproof on the cushion, and the waterproofing should be extended to the brick tire mold, so that after pouring the concrete in the future, the waterproof can be turned up to the concrete wall, if the template is not used, the waterproof can not be done, so the method of using bricks as a template is adopted.

There are a few things to note:

1. The pay-off of the brick mold should be discussed and considered, considering the thickness of the brick mold plastering 15mm and the waterproof protective layer of the side wall of the brick mold.

2. The height of the brick mold should consider the height of the waterproof protection measures on the brick mold.

Quantity calculation method of brick tire mold:

It is suitable for the engineering quantity without a takeoff model and only calculates the quantity of the brick formwork (application scenario: general contracting to the team takeoff).

This method has a large statistical workload, which requires each position to calculate the engineering quantity, and it is also necessary to be quite familiar with the process, and the brain must be clear in the process of calculation. The calculations listed need to be detailed and reflect the calculated quantities quickly.
