Thank you in advance for your help in looking at the reinforcement of the beam

Ground beam 7 size 250 * 650 stirrup encryption area spacing 100, non-encryption area furniture 200 and two hoops upper long rib two circles 20 The left end of the upper corner bar is a circle 20 and to the span net length of 1 3 truncated The steel bar at the lower part of the junction of the main and secondary beams is the three length of the circle 20 and the circle 18 The other 6 of the structural reinforcement circle 12 is also the length of the arrangement Remember that the length of the arrangement in the support out of the bend 15d This figure of yours is a reinforcement diagram of the earthquake-resistant area, right?? If it weren't for the anchorage of the support, it wouldn't be 15d...

Ground beam 7, one span and one end cantilevered, cross-sectional size is 250mm * 650mm, stirrup diameter is circle 8, spacing encryption area 100mm, non-encryption area 200mm, two limb hoops, the upper through long bar is 2 20 (3 20 at the bearing), the lower through long bar is 2 20 plus 1 18 (18 is placed in the middle), and the structural bar is 6 12 (3 on each side).

DL1 section cantilever cross-sectional size 250 width 650 height stirrup first-class steel 8 large-spacing infill area 100 non-infill area 200 spacing upper longitudinal bar 2 20 secondary rigid left support reinforcement 3 secondary reinforcement of 20 secondary reinforcement mid-span reinforcement 20, 18 side reinforcement 6 12 secondary reinforcement.

Interpretation of stirrup representation method:

1) 8@100 200(2) means that the stirrups are 8 diameter first-class steel, the spacing between the infill area is 100, the spacing of the non-infill area is 200, and the double limb hoops.

2) 8@100 200(4) means that the stirrups are 8 first-class steel with a diameter of 8, the spacing between the infill areas is 100, the spacing of the non-infill areas is 200, and the limb hoops.

3) 8@200(2) means that the stirrups are 8 diameter first-class steel, the spacing is 200, and the double limb hoops.

4) 8@100(4) 150(2) means stirrups are 8, the spacing of the infill area is 100, the limb hoops, the spacing of the non-infill area is 150, and the double limb hoops.

Beam lower reinforcement representation method: (marked on the lower part of the beam).

1) 4 25 means that there is only one row of main reinforcements, and 4 25 all extend into the support.

2) 6 25 2 4 means that there are two rows of reinforcement, the upper reinforcement is 2 25, and the lower disturbance number reinforcement is 4 25.

3) 6 25 (-2 ) 4 means that there are two rows of reinforcements, the upper reinforcement is 2 25, does not extend into the support, and the lower reinforcement 4 25, all extends into the bearing.

4) 2 25 + 3 22(-3) 5 25 means that there are two rows of ribs, and the upper ribs are 5. 2 25 extends into the support, 3 22, does not extend into the support. Lower rib 5 25, arranged through length.

When the beam is reinforced, attention should be paid to the setting of the waist tendon, and the unilateral reed finger bar waist tendon should be greater than . When the beam is reinforced, the anchorage length of the beam should be fully considered, especially the secondary beam, which should meet the requirements of the atlas as much as possible.

It can be understood in this way, sometimes the force of the component is relatively small, so small that it can be ignored or the remaining bucket is smaller than the minimum reinforcement ratio, at this time, the mu of the component is the minimum reinforcement rate control, and the reinforcement according to the minimum reinforcement ratio is the structural reinforcement. It should also be noted that when grinding with vertical grinding, for example, the maximum spacing of stressed steel bars, such as 350 wide beams, the minimum reinforcement ratio of 2 25 may be enough, but the beam stirrups of 350 require 4 limb stirrups, then at least 4 steel bars must be obtained, and then the structural reinforcement must meet the minimum reinforcement ratio and the structural system two aspects

The maximum reinforcement ratio of the longitudinal tensile reinforcement of the beam support.

High gauge: during seismic design, the reinforcement ratio of longitudinal tensile reinforcement at the beam end should not be greater than 2 5, should not be greater than 2 75; When the ratio of the tension reinforcement at the beam end is greater than 2 5, the reinforcement ratio of the compression reinforcement should not be less than half of the tension reinforcement.

2. The minimum reinforcement ratio of the longitudinal tensile reinforcement of the beam support.

1）."High Gauge": The minimum reinforcement percentage of longitudinal tensile reinforcement min( ) should not be less than the greater of 0 2 and 45ft fy when the non-seismic design of the world roll; When designing for seismic resistance, it should not be less than the values specified in Table 6 3 2-1.

When the beam is reinforced, attention should be paid to the setting of the reed finger bar waist bar, and the unilateral waist bar should be greater than . When the beam is reinforced, the anchorage length of the beam should be fully considered, especially the beam with Hu Ci Teasing Mountain, which should meet the requirements of the atlas as much as possible.

There is no structural reinforcement for the foundation beam, and there is only a simple reinforcement according to the minimum structure. If the reinforcement ratio of the longitudinal reinforcement of the beam is not less than the cross-sectional area of the beam, the stirrup diameter is not less than 8mm, and the distance between the trousers is not more than @250 and not more than the beam width.

The hail ratio of the longitudinal stressed steel bar at the beam end should not be greater than.

In order to meet the requirements of rock modification with minimum reinforcement rate in the support of longitudinal tensile reinforcement reinforcement and cross-source annihilation shed, there can be a standard check.

The ratio relationship between the top and bottom reinforcement areas of the beam ends.

The torsion ribs in the beam are marked in the drawings, and they can be placed according to the number of drawings, and the anchorage length can be paid attention to the structural requirements, and the net height of the beam is greater than 450mm.

Straight lines, drawn one by one, careful, serious. Label the position, align, unified and beautiful. auspicious closure is not heavy or leaky.

Concentrate on marking the pattern crack tic-tac-toe. Generally, it is matched according to the structure. The vertical reinforcement ratio in the satwe parameter can be adjusted according to the engineering needs of the code, when the edge member is equipped with .

The gold allocation rate of the longitudinally stressed steel bar of the beam end source shed should not be greater than.

2.The support and span of the longitudinal rock modification tensile reinforcement should meet the requirements of the minimum reinforcement ratio when the hail is subjected, and there can be a standard check.

3.The ratio relationship between the top and bottom reinforcement areas of the beam ends.

Liang'an structural reinforcement needs to calculate the length of the amount and the number of holes, as well as the length and width of the steel plate and the carbon step of Dong Xu, the steel bar, occupy the carbon step, and then stick.

The height of the rectangular cross-section beam is generally taken than h b; The height-to-width ratio of the T-section beam is H b, which is generally taken in addition to b for the beam rib and the width of the mu) Xiang Chasen. In order to unify the size of the formwork and facilitate construction, the cross-sectional width of the beam is usually taken as b 120mm, 150mm, 180mm, 200mm, 220mm, 250mm, 300mm, no filial piety 350mm and other sizes; The cross-sectional height of the beam is usually taken as h 250mm, 300mm, 350mm, 750mm, 800mm, 900mm, 1000mm and other sizes.

When a main beam is set up with a secondary beam, cracks will occur at the junction of the primary and secondary beams. In order to prevent the occurrence of cracks in the bridge, it is necessary to add suspension bars at the junction position of the primary and secondary beams.

In the case of a small cantilever answering the bird's shout, the reinforcement at the end of the cantilever is smaller than the reinforcement on the other side of the support, and the reinforcement of the internal support can be pulled through to the outer cantilever end in whole or in part. For roof frame beams with side posts and corner posts as end supports.

When the reinforced concrete beam is reinforced, the reinforcement must be selected according to the "Code for Concrete Structure Design Tremor Imitation Meter" (GB 50010-2002), and the waist bar must meet the requirements of strips and open-hole reeds.

When the reinforced concrete beam is reinforced, the reinforcement must be selected according to the "Code for Concrete Structure Design Stimulation Meter" (GB 50010-2002), and the waist bar must meet the requirements of strip and Mingdong reed.

At the junction of the primary and secondary beams, if the secondary beam is rigidly connected, the negative bending moment at the beam end will produce torque to the main beam.

Structural reinforcement is the reinforcement that is set according to the construction needs in the reinforced concrete structure. In contrast to the stressed reinforcement, the structural reinforcement does not bear the main force.

The code requires that the height of the beam belly is greater than or equal to 450, and the side structure reinforcement should be set.

The amount of reinforcement used for a beam is roughly 35 75 kg square meters (excluding basements, and the height does not exceed 150 meters).

The main sedan chair of the activity is as the title: Helping people to infiltrate self-help and promote the professional knowledge of social workers; Serve the society and promote the construction of rural culture. 2. Background of the Burning Spine Project At present, the material life of Chinese farmers is generally more than enough food and clothing.

With the improvement of material life, the peasants showed a strong demand for spiritual and cultural life. However, due to the grassroots public cultural products.

Check whether the router is loose in the line and disturbance, and if it doesn't work, turn off the main switch of the road early auspicious device, take a break from the land shed, and then reopen it. If it still doesn't work, just call ** and let someone come to check what the problem is.

Oh, it is a frame structure of a special-shaped column of a six-story residential building, and the beam layout of a certain floor, flat annotation, detailed enough, can be enlarged to see.

I think the owner doesn't need to look at the drawings at all, and the regular drawings like this must be built by a regular construction unit. You only need to control the contract and find a supervisor to check the quality. Don't be surprised, to be honest, if you don't understand architecture for three or two days, you can figure out the flat method and be able to draw steel bars for planning, that's a genius.

Last week, I drew two school building structure drawings for others, and I was fished, and I haven't smelled the bait for 100 points! Hot buns beat the dog - there is no return.

This diagram is vague.

You look at the 03G101 series atlas.

Hello, I'm here to answer for you.

1.The stirrups shelved out of the secondary beam are encrypted to 3@50, and the stirrup diameter is the same as that of the main inner beam, which refers to a structural treatment when the main beam is used as the secondary beam supporting seat, that is, the main beam intersects at the position of the secondary beam, that is, the position of the secondary beam at the main beam, the stirrups of the main beam need to be encrypted, and there are 3 spacing of 50 on each side of the secondary beam, and the reinforcement specifications are the same as the stirrups of other parts of the main beam. The figure below is for illustration.

2.The beam resting on the wall, 240 * 240 * 180 prefabricated concrete cushion block under the beam refers to if one end of the beam is placed on the wall, the concrete cushion block is added at the lower part of the beam, which is equivalent to padding the beam, but from 240 * 240 * 180 this cushion block is too small.

The longitudinal reinforcement is 4 12, the stirrups are 6@200, the width is 240, the height is 300, this is the ring beam, the beam section is 240*300, the four corner reinforcements are 4 12 arrangement, the stirrup diameter is 6 spacing 200

The infill is 3 with a spacing of 50mm, the prefabricated concrete cushion block is 240mm long, 240mm wide and 180m high, the longitudinal reinforcement of the ring beam is 4 rebar with a diameter of 12, the stirrup diameter is 6 with a spacing of 200mm, and the width of the ring beam is 240mm and the height is 300mm.

The four lines of numbers in the upper part of the beam are called centralized labeling. The second row (2) represents the limb hoops, and the next 2 are two HRB335 grade steel bars with a diameter of 25. (This is the elevation of the upper surface of the beam.)

In the plan, the upper and lower subscripts of the beam are called in-situ annotation, and the 6 25 steel bars on the upper mark are divided into two rows, with 4 in the upper row and 2 in the lower row.

The in-situ annotation refers to the actual (upper) or (lower) reinforcement that passes through the cross-section. Centralized annotation indicates that the beam is common everywhere. If there is a conflict between centralized labeling and in-situ labeling, the in-situ annotation shall prevail, that is, "in-situ annotation takes precedence".

This is the foundation, so I recommend looking for a book.

2 25, which means that the usual ribs are two steel bars with a diameter of 25mm; (Indicates the upper elevation of the beam; 6 25 is to say that the upper part of the end support is the steel bar of 6 and 25, which is arranged in two layers, with 4 heels on the upper layer and 2 on the lower layer; When the position of centralized labeling and in-situ labeling is the same, in-situ labeling is generally referred to. For example, you said 6 25 this place, the upper reinforcement is two corners of two 25 through long ribs, there are two 25 end support reinforcement in the middle, to the span one-third, there are two end support reinforcements below the two corners, also to one-third of the place.

If you don't understand, take the drawings to the construction site and see the steel bars tied by others, and you will understand it at once.

Seismic rating and concrete marking.

Then in accordance with the drawing specifications required by the drawings to reinforce, pay attention to the position of the solder joint, the length of the anchorage, the length of the extension must be subtracted, try to use the raw material butt welding can save materials, the remaining can be made of additional reinforcement of the beam, not enough length can be butt welding. Budget: the span of the beam, whether it is seismic or not, the seismic rating, the approximate load on the beam.

Whether the cantilever balcony, and then the model and number of tension and compression ribs of the fixed beam, when the height of the fixed beam is too high (more than 600, including 600), the torsion bar (waist tendon) can be prepared, and the beam height minus the protective layer (5 cm) is calculated from the main reinforcement.
