The first floor is the only place for the whole building, and it is also the easiest to hear the noise from other places.
In the construction project of Jiangsu Nantong Second Construction Group Co., Ltd., we wait for you in Asia Pacific Interior Design network.
We are waiting for you on the Asia Pacific Interior Design Network ———————– long press the identification QR code to pay attention to us to buy a house with a small courtyard on the first floor.
Therefore, when purchasing, we must avoid those house types with poor lighting.
It’s very cool! What can and can’t be bought in the courtyard on the first floor? How to design it after buying it? Today we’re going to popularize science! In fact, most people who buy a house on the first floor pay for the garden yard.
Structural flanging formwork installation process, construction setting out → placement and welding Construct the flanging positioning reinforcement → assemble the inner flanging formwork → place the inner formwork in place and adjust the position → place the outer formwork in place and adjust the position → correct the formwork → tighten one end of the external corner screw of flanging with mountain clamp and nut → install the instrumental reinforcement clamp → inspection and acceptance → 3D disclosure of animation construction operation points of concrete pouring 1.
The 15mm thick bamboo plywood with good quality is used as the formwork panel to improve the turnover times of the formwork.
Key points for fabrication of structural flanging reinforcement: make positioning reinforcement mold according to the drawing to ensure consistent size.

It is easier to become dark and humid and breed mosquitoes.
In order to avoid the disadvantages caused by the traditional flanging construction, Nantong second construction group has studied and formulated the one-time forming construction method of architectural engineering structure flanging, which has achieved remarkable results in the application of many projects of the company, avoiding the leakage risk of flanging root in kitchen and bathroom, fire corridor, roof and so on.
Some people live poetic and carefree.
The traditional construction adopts the methods of secondary formwork erection and concrete pouring, Due to the construction joint between the structural flanging and the structural floor slab in the secondary structure construction, it is easy to have the common problem of leakage or moisture return.
Generally, some of the yards on the first floor of small high-rise (7-18 floors) have property rights.
Very narrow, the courtyard has poor daylighting.
If the first floor has an overhead floor or an underground garage, the moisture-proof measures will be better, which can avoid moisture to a certain extent.

Forming of flanging formwork 6.
After the top plate reinforcement is bound, the fabricated structural flanging formwork shall be lifted to the structural flanging place by tower crane, placed on the welded positioning reinforcement, and the formwork shall be straightened by pulling wire; One end of the screw at the external corner of the structural flanging shall be tightened with nuts and mountain clamps.
Set a star in the upper right corner of the home page, so you won’t miss any articles.
Structural flanging integral formwork production process, familiar with construction drawings → formwork scheme design → formwork blanking according to structural flanging size → piece up bamboo plywood according to size → fix horizontal square steel keel on bamboo plywood according to spacing with page tail nails → number bamboo plywood with red paint 2.
The horizontal keel of formwork is 40 × 40mm square steel, and the keel and formwork are fixed with page tail nails.
Flanging concrete forming construction engineering structure flanging one-time forming construction method, the structure flanging and floor structure are poured at one time to avoid the formation of structural construction joints by secondary pouring, increase structural self waterproofing, reduce construction procedures and leakage complaints of small owners after house delivery, and reduce project construction costs; Reduce secondary formwork erection and roughening, effectively control waste pollution caused by secondary construction, replace wood with steel, and achieve green construction; The overall assembly of instrumental formwork has the advantages of high installation efficiency, good forming effect, convenient construction, labor saving, cost reduction and efficiency increase.
Finally, the tool reinforcement clamp shall fix the formwork according to the specified spacing and pour it at the same time with the floor concrete, so as to achieve the purpose of one-time structural forming of structural flanging.
Such a house is the best.
Therefore, when selecting a building, we should investigate the surrounding environment.
In addition, it’s best to have a look at the master plan of the building.
If you spend money to buy it, it is yours.

Welcome to recommend us to your family and friends.
We must avoid the entrance of the underground garage and the main traffic roads in the community.
If the yard has no property right, the developer promises to buy the first floor to send the yard and take the initiative to help you enclose it, or there is no fence at all.
Otherwise, listening to all kinds of noise every day and sleeping will become a problem.
See if it is next to the septic tank, water pump room, substation room and other dangerous positions.
The diameter of reinforcement is 12mm, and the reinforcement must be fully welded to ensure the welding quality and avoid the falling off of reinforcement and reinforcement when stressed.
Key points of formwork assembly: fix the square steel keel on the back of bamboo plywood with page tail nails in advance, with an internal spacing of 100mm, and the lower square steel is 2cm away from the lower opening of the formwork, so as to facilitate the internal corner calendering of concrete; Then the formwork is connected into a whole through the external corner fixing screw, mountain clamp and nut.
Key points for pouring structural flanging together with floor concrete: secondary closing shall be carried out at the structural flanging surface and the internal corner of the structural flanging and the floor to improve the appearance.
Most of these yards belong to the greening land of all owners, and the developers sell them in violation of regulations.
Generally, a concrete structure flanging with a height of no less than 200mm shall be made for kitchen and bathroom, fire corridor and roof before masonry.
So we must pay attention to the property right of the yard.
Construction process principle: according to the size of the drawing, the positioning reinforcement and overall formwork for flanging shall be fabricated in advance: the waste reinforcement head shall be welded according to the wall size of the drawing, the positioning reinforcement of the guide wall and the tool type reinforcement clamp for fixing the formwork; Make and assemble the bamboo plywood according to the size of the wall, and then use 40mm × 40mm square steel is fixed on the bamboo plywood as a horizontal back Leng according to the standard spacing, and finally the bamboo plywood and horizontal back Leng are connected into a whole with screws and page tail screws.
Key points for fabrication of special fixed screw at the external corner of flanging: weld a screw with a diameter of 12mm on one side of the square steel, the screw and the square steel must be fully welded, and the length of the screw shall be determined according to the size of the formwork and the square steel to ensure that the exposed thread is not less than 3cm.
