Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A shear wall 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 9.

As shown in fig. 1 to 8b, a shear wall 100 according to an embodiment of the present invention includes a plurality of rectangular steel pipe columns 1, a plurality of steel pipe beams 2, and a plurality of steel bars 3. In the description of the present invention, "a plurality" means two or more.

Specifically, a plurality of first reinforcement holes 11 are formed at intervals on each rectangular steel pipe column 1. A plurality of steel tubular beams 2 wear to establish on rectangle steel-pipe column 1, and a plurality of steel tubular beams 2 include a plurality of first steel tubular beams 21 and a plurality of second steel tubular beams (not shown), and a plurality of first steel tubular beams 21 are parallel to each other, are formed with the second lacing wire hole 22 that a plurality of intervals set up on every steel tubular beam 2, and a plurality of second steel tubular beams are parallel to each other, and every first steel tubular beam 21 and every second steel tubular beam mutually perpendicular. The plurality of steel bars 3 comprise a plurality of first steel bars 31 and a plurality of second steel bars 32, the plurality of first steel bars 31 are respectively arranged on the plurality of first bar penetrating holes 11 in a penetrating way, and the plurality of second steel bars 32 are respectively arranged on the plurality of second bar penetrating holes 22 in a penetrating way.

For example, in the examples of fig. 4, 5 to 7, the first punched holes 11 are formed in the rectangular steel pipe column 1, and a plurality of the first punched holes 11 are provided at intervals in the rectangular steel pipe column 1. The second reinforcement through holes 22 are formed in the steel pipe beam 2, and the plurality of second reinforcement through holes 22 are provided at intervals in the steel pipe beam 2. First reinforcing steel bars 31 penetrate through the first reinforcing steel bar penetrating holes 11, and second reinforcing steel bars 32 penetrate through the second reinforcing steel bar penetrating holes 22. Specifically, during processing, the first reinforcing bars 31 are respectively inserted through the first reinforcing bar passing holes 11 in two opposite side walls of the rectangular steel pipe column 1. The first reinforcing bars 31 and the second reinforcing bars 32 are perpendicular to each other, and the second reinforcing bars 32 extend in the vertical direction. From this, through above-mentioned setting, a plurality of first reinforcing bars 31 and a plurality of second reinforcing bar 32 can improve the structural strength of whole shear force wall 100, compare with the traditional mode of wearing to establish the reinforcing bar in the concrete, and a plurality of reinforcing bars 3 can be firmly fixed on rectangle steel-pipe column 1 and steel-pipe beam 2, can avoid the problem that the concrete ftractures to appear, make shear force wall 100 can increase the rigidity, the intensity and the ability of anti-collapsing of whole building better.

According to the utility model discloses shear force wall 100, wear to establish a plurality of first reinforcing bars 31 in a plurality of first muscle holes 11 through at a plurality of rectangle tubular steel poles 1, and wear to establish a plurality of second reinforcing bars 32 in a plurality of second muscle holes 22 of a plurality of tubular steel poles 2, whole shear force wall 100's structural strength and shear resistance have greatly been strengthened, and a plurality of first reinforcing bars 31 and a plurality of second reinforcing bars 32 can be firmly fixed on rectangle tubular steel pole 1 and tubular steel pole 2, can avoid the problem that the fracture appears in the concrete, make shear force wall 100 can increase the rigidity of whole building better, intensity and anti-collapse ability.

In some optional embodiments of the present invention, referring to fig. 1, the shear wall 100 includes a plurality of light steel joists, the upper and lower ends of each light steel joists are anchored with the corresponding steel pipe beams 2, and the vertical light steel joists on both sides of the rectangular steel pipe column 1 are anchored with the corresponding rectangular steel pipe column 1. In this way, the integrity of the shear wall 100 may be ensured.

In some embodiments of the present invention, as shown in fig. 5 and 6, the first lacing holes 11 and the second lacing holes 22 may be both circular holes. Therefore, on one hand, the first reinforcing steel bar penetrating hole 11 and the second reinforcing steel bar penetrating hole 22 can enable the reinforcing steel bar 3 to penetrate through the reinforcing steel bar, so that the rectangular steel pipe column 1 and the steel pipe beam 2 have anchoring performance; on the other hand, the shapes of the first and second reinforcement through holes 11 and 12 can be matched with the shape of the steel bar 3, thereby facilitating the assembly of the steel bar 3.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the first lacing holes 11 and the second lacing holes 22 may also be elliptical holes (not shown), long circular holes (not shown), polygonal holes (not shown), or the like. Therefore, when the first reinforcement through hole 11 and the second reinforcement through hole 22 are polygonal holes respectively and are matched with the shape of the steel bar 3, the first reinforcement through hole 11 and the second reinforcement through hole 22 can well position the steel bar 3. When the sizes of the first reinforcement penetrating hole 11 and the second reinforcement penetrating hole 22 are larger than the size of the steel bar 3, for example, when the first reinforcement penetrating hole 11 and the second reinforcement penetrating hole 22 are elliptical holes or oblong holes, the first reinforcement penetrating hole 11 and the second reinforcement penetrating hole 22 can also be used as grout discharging holes, so that concrete grout can pass through a gap between the steel bar 3 and the first reinforcement penetrating hole 11 or the second reinforcement penetrating hole 22 from one side of the rectangular steel pipe column 1 or the steel pipe beam 2 and flow to the other side of the rectangular steel pipe column 1 or the steel pipe beam 2. It is understood that the shapes of the first and second lacing holes 11 and 22 can be specifically set according to actual requirements to better meet the actual application.

Further, referring to fig. 7, when the first rebar penetration holes 11 are round holes, the plurality of first rebar penetration holes 11 on two adjacent side walls of each rectangular steel pipe column 1 are staggered in the longitudinal direction of the rectangular steel pipe column 1. Therefore, the reinforcing steel bars 3 penetrating through the first reinforcing steel bar penetrating holes 11 on the two adjacent side walls can be staggered from each other, interference is avoided, and the first reinforcing steel bars 31 can be better arranged on each side wall of the rectangular steel pipe column 1 in a penetrating mode.

Alternatively, when the first rebar penetration holes 11 are elliptical holes or oblong holes extending in the longitudinal direction of the steel pipe column, the plurality of first rebar penetration holes 11 on two adjacent side walls of each rectangular steel pipe column 1 may be located in the same horizontal plane (not shown). For example, the first reinforcing bars 31 passing through the adjacent two side walls may be respectively positioned at the upper and lower sides of the oblong or oval first reinforcing bar passing hole 11. Therefore, the first reinforcement through holes 11 arranged in this way can also enable the reinforcing steel bars 3 passing through the first reinforcement through holes 11 on two adjacent side walls to be staggered with each other, so that interference is avoided.

In some embodiments of the present invention, as shown in fig. 5 and fig. 6, the first plurality of tendon passing holes 11 on each side wall of each rectangular steel pipe column 1 are divided into a plurality of groups of holes 111, the groups of holes 111 are arranged along the longitudinal interval of the rectangular steel pipe column 1, and each group of holes 111 includes at least two first tendon passing holes 11. For example, in the example of fig. 5 and 6, each group of hole groups 111 includes two first rebar holes 11, and a plurality of groups of hole groups 111 are arranged at intervals on the side wall of the rectangular steel pipe column 1. Thus, with the above arrangement, the number of the first reinforcement holes 11 is large, and the structural strength of the entire shear wall 100 can be further enhanced by passing the plurality of first reinforcements 31 through the plurality of first reinforcement holes 11.

Optionally, the distance between two adjacent sets of hole groups 111 is d, and d satisfies: d is more than or equal to 15cm and less than or equal to 25 cm. Specifically, for example, when the distance d < 15cm, the distance between the adjacent two sets of hole groups 111 is too small, the structural strength of the rectangular steel pipe column 1 may be reduced; when the distance d is larger than 25cm, the distance between two adjacent hole groups 111 is too large, so that the number of the reinforcing steel bars 3 penetrating through the rectangular steel pipe column 1 is small, and the connection is not firm. Therefore, d is larger than or equal to 15cm and smaller than or equal to 25cm, so that the rectangular steel pipe column 1 can have higher structural strength while the shear wall 100 has better shear strength and tensile strength, and the whole shear wall 100 can have higher structural stability.

Further optionally, d is 20 cm. Therefore, when the distance between two adjacent sets of hole groups 111 is 20cm, the number of the first reinforcement penetrating holes 11 on the rectangular steel pipe column 1 is appropriate, so that the entire shear wall 100 has excellent mechanical properties.

In some embodiments of the present invention, referring to fig. 1-3, a wire mesh 311 is fixed to the outer side surfaces of the first and second reinforcing bars 31 and 32. From this, wire net 311 that so sets up mixes as an organic whole with the thick liquid that concreting oozes (the batch is scraped smoothly after the water is received to the surface), has strengthened bulk strength and has prevented to produce the crack when the concrete shrink. Before the steel wire mesh 311 is fixed without being demolded, the water and electricity wire pipe and the wire box need to be pre-embedded in advance, so that the secondary grooving can be avoided from influencing the structure.

Further, referring to fig. 6, the plurality of second reinforcing bars 32 include a plurality of second long reinforcing bars 321 and a plurality of second short reinforcing bars 322, the plurality of second long reinforcing bars 321 are staggered from the plurality of second short reinforcing bars 322, and a length of each second long reinforcing bar 321 extending out of the upper surface of the tubular beam 2 is greater than a length of each second short reinforcing bar 322 extending out of the upper surface of the tubular beam 2. For example, in the example of fig. 6, the second reinforcement holes 22 are formed on the upper surface and the lower surface of the steel tubular beam 2, two second reinforcements 32 spaced apart are both the second long reinforcements 321 or both the second short reinforcements 322, and two adjacent second reinforcements 32 are the second long reinforcements 321 and the second short reinforcements 322, respectively. By the arrangement, the tensile strength and the shear strength of the whole shear wall 100 can be enhanced, so that the shear wall 100 can bear larger vertical load and horizontal load.

The construction method of the shear wall 100 according to the embodiment of the second aspect of the present invention, as shown in fig. 9, includes the following steps:

firstly, inserting a beam inner sleeve into a column beam node in a factory, and fixing a steel pipe beam 2 on site;

secondly, laying and installing a floor slab on the upper surface of the steel pipe beam 2;

thirdly, penetrating first reinforcing steel bars 31 into the first reinforcing steel bar penetrating holes 11, and penetrating second reinforcing steel bars 32 into the second reinforcing steel bar penetrating holes 22, so that the second reinforcing steel bars 32 penetrate through the steel pipe beam 2 and the rectangular steel pipe column 1;

and fourthly, pouring concrete of the rectangular steel pipe column 1, the steel pipe beam 2 and the floor slab. Alternatively, the concrete may be foam concrete, and the overall load of the shear wall may be reduced due to the light self weight of the foam concrete.

Binding a plurality of first steel bars 31 and wall steel bars, and supporting a mould-removal-free steel wire net to form a shear wall 100 framework;

and sixthly, pouring concrete again to form the shear wall 100.

According to the utility model discloses shear force wall 100's construction method, through adopting above-mentioned step, can avoid the problem that the fracture appears in the concrete, make shear force wall 100 can increase the rigidity, the intensity and the ability of anti collapsing of whole building better.
