Abstract

The utility model relates to a new pattern steel bar which is convenient for the laying operation. The outer surface of the steel bar is provided with bamboo joint ribs 2, 3, 4, 5, 6 with the interval of 5cm and the crescent rib 7 is arranged among each bamboo joint rib which is non-intersect into 60 degrees with the main rib. The corresponding number of paths of the crescent ribs are arranged according to the bar diameters which vary in size. The phi 10, phi 12 and phi 14 are provided with five paths. The phi 16, phi 18, phi 20 and phi 22 are provided with four paths. The phi 25and phi 28are provided with three paths. The phi 32, phi 36 and phi 40 are provided with two paths. When working, laborers make no use of equinox scribed line and can select directly conveniently according to the distances which are needed to band. The distance between the bamboo joint rib 2 and the bamboo joint rib 3 is 5cm. The distance between the bamboo joint rib 2 and the bamboo joint rib 4 is 10cm. The distance between the bamboo joint rib 2 and the bamboo joint rib 5 is 15cm. The distance between the bamboo joint 2 and the bamboo joint rib 6 is 20cm. So the construction of the steel bar can be convenient.

Description

Be convenient to the new reinforcing steel bar of colligation construction

Affiliated technical field

The utility model relates to a kind of construction of being more convenient for, and especially more can embody the new reinforcing steel bar of its superiority in the bigger civil engineering of amount of reinforcement.

Background technology

At present, the hot-rolled reinforced bar of China's production is that cross rib becomes 60 ° of angle non-intersect crescent cross rib notched barss with main rib.In work progress, the workman need be according to the mesh size of beam, tie muscle spacing or wall, slab muscle, to reinforcing bar with chalk rule branch, colligation then.Because the workman draws mark to each root reinforcing bar, particularly joist, plate muscle, add that the mark that chalk is done is easy to come off in handling process, so workmanship is difficult to be guaranteed, and line is very time-consuming again, effort, and especially in the middle of the modern high-rise building construction, each procedure operation is all raced against time, present traditional line mode needs of development that have been out of step with the times press for a kind of need not the line and can make things convenient for the reinforcing bar binding technology to occur.

Summary of the invention

In order to overcome the problem that existing reinforcing bar is not easy to constructing operation, this appearance design provides a kind of new reinforcing steel bar.This new reinforcing steel bar can not only convenient construction, and more can guarantee construction quality, can also reduce the pollution of chalk dust, saves time, laborsaving, has improved work efficiency of workers, has shortened the duration of construction, and has not increased cost of production.

The technical scheme that its technical problem that solves the utility model adopts is: every interval 5cm design is intersected at an angle of 90 ring rib with main rib together on the scale notched bars, this rib height, wide the same with main rib, in each ring rib, establish original shape and become 60 ° of non-intersect crescent moon ribs in angle with main rib, its size, area is to guarantee that meeting GB requires to be as the criterion, the model of reinforcing bar, sign is located at the centre of ring rib, the quantity of crescent moon rib is respectively according to the bar diameter size in each ring rib: Ф 10, Ф 12, Ф 14 establishes 5 roads, Ф 16, Ф 18, Ф 20, Ф 22 establishes 4 roads, Ф 25, Ф 28 establishes 3 roads, and Ф 32, Ф 36, Ф 40 establishes 2 roads.Modal colligation spacing is: @100mm, @150mm, @200mm in the middle of architectural design, encryption place Shi @50mm, the spacing of other size is seldom used, so the workman need not rule and just can represent 5cm with one ring rib in work progress, two road ring ribs are represented 10cm, three road ring ribs are represented 15cm, and on behalf of 20cm, four road ring ribs come assembling reinforcement just to be easy to.If any the spacing of specific (special) requirements, by former method construction also not influence because the work of this part workload is considerably less comparatively speaking.Skilled bar bender's a glance just can be told the reinforcing bar model of all size, and selecting a few road of this usefulness ring rib in process of binding is lead-pipe cinch as spacing.

The beneficial effects of the utility model are: save crossed process one, reduce labour cost, steel manufacturer does not increase cost just can make reinforcing bar appreciate, unit in charge of construction can guarantee easily that more workmanship is (because of all there is the ring rib at each position of each root reinforcing bar, be convenient to colligation and location), environmental protection (reducing chalk pollutes) helps the reduction of erection time, also can be convenient to the examination (need not measure spacing with a yardstick) of supervisor.

The specific embodiment

In the reinforcing bar binding process of plate, wall, the reinforcing bar cutting length is not the integral multiple of 5cm sometimes, has the remnant less than 5cm.Because job specfication stipulates that the first road horizontal bar (vertical muscle) is apart from vertical muscle (horizontal bar) end 5cm, if tie up the first road horizontal bar (vertical muscle) so just get odd part when the remnant is arranged, when spacing is 5cm such as accompanying drawing 1-1, get ring rib together between the

ring rib

2 and 3, when spacing is 10cm, as accompanying drawing 2-1, between the

ring rib

2 and 4, get two road ring ribs, when spacing is 15cm, as accompanying drawing 3-1, between the

ring rib

2 and 5, get three road ring ribs, when spacing is 20cm, as accompanying drawing 4-1, between the

ring rib

2 and 6, get four road ring rib colligations.In wall, slab muscle process of binding, guarantee on the first road horizontal bar, vertical muscle or the major and minor muscle all colligation points at grade, the body of wall reinforcing bar is connecing when high, lap length will be consistent, cutting length is selected the integral multiple of 5cm for use, to guarantee all levels of corresponding ring rib.

In the reinforcing bar binding process of beam column, the first road stirrup will guarantee that all colligation points all on same plane, select the ring rib colligation of a few road of this usefulness according to design pitch again.The connecing height and will guarantee that also cutting length is a just integral multiple of 5cm of post muscle, overlap joint (welding) length is wanted unanimity.In a word, the workman is as long as skillfully hold once the spacing assembling reinforcement easily to four ring rib representatives.

Certainly, each ring rib also can be done round dot on former reinforcing bar, triangle comes mark, or the mark of other display scales is all within the utility model protection domain.

Claims

1, a kind of new reinforcing steel bar of being convenient to colligation construction is characterized in that: every interval 5cm establishes together with main rib and intersects at an angle of 90 ring rib on the external surface of reinforcing bar.

2, according to the described new reinforcing steel bar of being convenient to colligation construction of claim 1, it is characterized in that: establish the non-intersect crescent moon rib that becomes 60 ° of angles of original shape and main rib in the middle of each ring rib, the quantity of crescent moon rib is looked the bar diameter size and is followed successively by: φ10, φ12, φ14 establish 5 roads, φ16, φ18, φ20, φ22 establish 4 roads, φ25, φ28 establish 3 roads, φ32, φ36, φ40 establish 2 roads.
