Modular shear force wall ladder muscle has reduced the welding volume of original ladder muscle to bolt, screw rod are main functional component, and through adjusting bolt hole site, the length of connecting screw rod in order to adapt to different wall thickness, reinforcing bar interval, not only shortened the processing cycle of original ladder muscle greatly, the suitability is strong moreover, and application scope is wider.
Description
Technical Field
The utility model belongs to the technical field of the shear force wall, in particular to modular shear force wall ladder muscle.
Background
The shear wall of the residential building is a core stressed component of a main structure, the deviation of reinforcing steel bars is a common quality problem which often occurs, and adverse effects are generated on the stress of the structure. In the prior art, C12 steel bars are mostly adopted to be welded to manufacture ladder bars, two long steel bars are used as main bars, transverse bars with certain lengths are welded in the middle of the ladder bars to form a frame structure similar to a ladder, clamping steel bars are welded on the outer edges of the main bars, the ladder bars are obviously used for positioning the steel bars of the shear wall and can play a good role, but because the shear wall of a residential building is more, each wall needs to be independently sized and processed according to the wall length, the manufacturing is labor-consuming and time-consuming, accurate steel bar blanking is needed, a large amount of manual welding is needed, the ladder bars can not be randomly adjusted when meeting different wall thicknesses and steel bar intervals, the short steel bar welding has higher requirements on welders, and in addition, when the ladder bars are bound to the middle section in practical application, the ladder bars need to be placed in place for the second time.
Therefore, how to simply and quickly manufacture a large number of ladder bars needed on a construction site and meet the requirements of different wall lengths is a problem which needs to be solved urgently at present.
Disclosure of Invention
The utility model aims at providing a modular shear force wall ladder muscle has reduced the welding volume of original ladder muscle to bolt, screw rod are main functional component, and through adjusting bolt hole site, the length of connecting the screw rod in order to adapt to different wall thickness, reinforcing bar interval, not only shortened the processing cycle of original ladder muscle greatly, the suitability is strong moreover, and application scope is wider.
The utility model aims at realizing through the following technical scheme:
the utility model provides a modular shear force wall ladder muscle, the band iron by two parallel arrangement forms the main frame, punches a hole in pairs according to the interval S1 of vertical reinforcing bar on the shear force wall on two band irons for fixed screens bolt connects through connecting screw between two band irons, connecting screw and two band irons respectively adopt a pair of nut fastening, and two adjacent connecting screw' S interval S2 are 600mm ~800mm, thereby change the distance between two band irons of different length according to the distance of shear force wall horizontal reinforcing bar.
Furthermore, the flat iron is galvanized flat iron, and the specification of the flat iron is 40 × 4 mm.
Furthermore, the bolt head of the clamping bolt penetrates out of the inner side of the ladder rib, and the outer side of the clamping bolt is screwed and fixed by adopting a matched nut.
Furthermore, the length of the connecting screw rod is 3 cm-5 cm.
Furthermore, the sharp corners at the two ends of the flat iron are polished.
Furthermore, the whole ladder muscle is brushed with anti-rust paint and ready-mixed paint.
The utility model discloses compare prior art's beneficial effect does:
1. the combined shear wall ladder rib can be adjusted and matched arbitrarily according to the thickness of a shear wall and the distance between reinforcing steel bars, the core construction of the combined shear wall ladder rib can realize 100 percent workshop machine tool processing, the hole can be punched accurately through a lathe, the work efficiency is high, the processing is convenient, the fastening of the residual bolts and the screw rods can be completed by adopting an electric wrench, only little labor is consumed, compared with the existing steel bar welding ladder rib, the combined shear wall ladder rib is time-saving and labor-saving, the position can be changed randomly during binding, the combined shear wall ladder rib is changed to the upper floor from the wall, and the on-site binding operation is convenient;
2. modular shear force wall ladder muscle, can be at will according to the wall length of difference, wall thickness, reinforcing bar interval transformation, if change the applicable different wall thickness of different length screw rods, return the factory and increase the applicable different reinforcing bar intervals of interval that punches a hole, after a later stage building site uses up, can connect the length according to the different wall length selection bolt of new building site, can have enough to meet the need for a long time and use, can perfectly replace current reinforcing bar welded shaping's ladder muscle.
Drawings
Fig. 1 is a schematic structural view of a combined shear wall ladder bar according to an embodiment of the present invention;
FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
fig. 3 is a cross-sectional view taken along line B-B of fig. 1.
Detailed Description
The technical solution of the present invention will be described in detail and fully with reference to the accompanying drawings, and obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a combined shear wall ladder bar, wherein a main frame is formed by two galvanized flat irons 1 arranged in parallel, the size of the flat iron is 40 × 4mm, and sharp right-angled portions at two ends of the flat iron can be subjected to rounding and chamfering treatment, so as to prevent operators from being scratched; punching holes in pairs on the two flat irons according to the distance S1 between the vertical steel bars 4 on the shear wall 6, wherein the hole diameter D =14mm, the holes are used for fixing the clamping bolts 2, the bolt heads of the clamping bolts penetrate out of the inner sides of the ladder bars, and the outer sides of the clamping bolts are screwed and fixed by matching nuts; the two band irons are connected through the connecting screw rod 3, the connecting screw rod and the two band irons are fastened through a pair of nuts respectively, the distance S2 between every two adjacent connecting screw rods is 600 mm-800 mm, the aperture D =14mm of a fixing hole of the fixedly connected screw rod, the clamping bolt with different lengths is replaced according to the distance of the horizontal steel bar 5 of the shear wall, and therefore the distance S3 between the two band irons is adjusted, and generally the length of the clamping bolt is kept at 3 cm.
Because the ladder bar is basically operated in the open air, the ladder bar is contacted with concrete and rainwater for a long time, after the ladder bar is processed to a finished product, antirust paint and mixed paint are integrally coated to improve durability, and regular cleaning and maintenance are needed in the using process.
