Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated shear wall structure for green buildings. Background Art

[0002] Shear walls, also known as earthquake-resistant walls or structural walls, are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes. With the development of green buildings and building industrialization, prefabricated buildings have gradually entered the market, and prefabricated shear walls have begun to gradually replace traditional cast-in-place concrete shear walls.

[0003] In the prior art, when installing an assembled shear wall, it is necessary to connect the connecting steel bars at the bottom of the assembled shear wall with the embedded steel bars embedded in the ground, and the connecting steel bars and the embedded steel bars are connected by grouting using a connecting sleeve, and the connecting sleeve is embedded in the wall, and grouting is performed through the grouting holes provided on the sleeve to perform grouting connection.

[0004] In the process of inserting the embedded steel bars into the connecting sleeves, since the connecting sleeves are embedded in the prefabricated shear walls, and the number of connecting sleeves is large, and some connecting sleeves have different positions, it is inconvenient to check the specific positions of the connecting sleeves, which makes it time-consuming to align the relative positions between the connecting sleeves in the prefabricated wall and the embedded steel bars below, thereby affecting the installation speed of the prefabricated wall, and therefore needs further improvement. Utility Model Content

[0005] In order to reduce the time spent on aligning the connecting sleeve with the embedded steel bars below, thereby increasing the installation rate of the prefabricated shear wall, the present application provides a prefabricated shear wall structure for green buildings.

[0006] The present application provides an assembled shear wall structure for green buildings, which adopts the following technical solutions:

[0007] A prefabricated shear wall structure for green buildings, comprising a connecting sleeve embedded in the shear wall and connecting steel bars embedded in the wall and passing through the connecting sleeve, wherein a through hole is formed through the bottom wall of the connecting sleeve for the embedded steel bars to slide through, a grouting hole is formed on the outer surface of the connecting sleeve at the lower end, and a grouting hole is formed on the outer surface of the connecting sleeve at the upper end; a positioning component for positioning the embedded steel bars is provided on the connecting sleeve, the positioning component comprises a connecting rope for connecting to the embedded steel bars and a pulling member for pulling the connecting rope, a through hole and a grouting hole are formed on the upper end of the connecting rope, and the pulling member is arranged outside the shear wall.

[0008] By adopting the above technical solution, after the shear wall is lifted, the connecting rope is then connected to the embedded steel bars. After the connection, the wall is brought close to the embedded steel bars, and the connecting rope is pulled by the pulling member to make the connecting rope taut. By observing the position of the connecting rope, the relative position between the connecting sleeve and the embedded steel bars can be checked to reduce the time spent on aligning the connecting sleeve with the embedded steel bars below, that is, to increase the alignment rate between the connecting sleeve and the embedded steel bars, thereby increasing the installation rate of the prefabricated shear wall.

[0009] Preferably, the pulling member comprises a pulling block connected to the connecting rope, and the size of the pulling block is larger than the outer diameter of the grouting pipe.

[0010] By adopting the above technical solution, the pulling block is pulled to drive the pulling of the connecting rope, so that the connecting rope itself is in a taut state. Moreover, since the cost of the pulling block itself is low, it is also convenient to connect with the connecting rope.

[0011] Preferably, a plurality of connecting sleeves are arranged at intervals along the length direction of the shear wall, the number of the connecting ropes is at least two, the pulling member includes a pulling rod fixedly connected to the connecting rope, the length direction of the pulling rod is parallel to the length direction of the shear wall, and a plurality of the connecting ropes are fixedly connected to one pulling rod.

[0012] By adopting the above technical solution, several connecting ropes are fixedly connected to a pulling rod, and by pulling a pulling rod, several connecting ropes are tightened, so that the relative positions between multiple connecting sleeves and embedded steel bars can be checked, thereby reducing the time spent on pulling several connecting ropes one by one.

[0013] Preferably, the positioning assembly also includes a connecting rod passing through the grouting pipe and a pulley rotatably connected to the connecting rod, the connecting rope is wound around the pulley, the size of the pulley is smaller than the inner diameter of the grouting pipe, and the connecting steel bar is located above the connecting rod.

[0014] By adopting the above technical solution, the connecting rope is pulled by the pulling member so that the connecting rope is in a taut state. At this time, the connecting rope may be worn and broken together with the connecting sleeve at the grouting pipe. Therefore, by providing a pulley, the wear of the connecting rope can reduce the impact on the subsequent observation of the position between the connecting sleeve and the embedded steel bars, and also reduce the resistance encountered when pulling the connecting rope.

[0015] Preferably, a connecting piece is provided on the connecting rod, and the connecting rod is detachably connected to the connecting sleeve via the connecting piece.

[0016] By adopting the above technical solution, the connecting rod can be disassembled from the connecting sleeve to reduce the influence of the connecting rod and the pulley in the connecting sleeve on the subsequent insertion of the embedded steel bars. It can also be used in the next shear wall to reduce the corresponding cost.

[0017] Preferably, the connecting member includes a sealing ring sleeved on the connecting rod and an elastic rubber pad wrapped around the outer peripheral wall of the sealing ring, the sealing ring is slidably inserted in the grouting pipe, and the elastic rubber pad abuts against the inner wall of the grouting pipe.

[0018] By adopting the above technical solution, the sealing ring is pressed to make the elastic rubber pad tightly against the inner wall of the grouting pipe to temporarily fix the connecting rod, so as to pull the connecting rope. When the embedded steel bars are inserted into the connecting sleeve, the sealing ring is pulled to pull the connecting rod and the pulley away from the connecting sleeve and the grouting pipe, so that the embedded steel bars can be smoothly inserted into the connecting sleeve.

[0019] Preferably, the connecting rod is exposed from the sealing ring, and an upper surface of the connecting rod is provided with a placement groove for placing the pulling member.

[0020] By adopting the above technical solution, the connecting rod is exposed to the sealing ring and a placement groove for placing the pulling piece is provided on the upper surface of the connecting rod, so that after the connecting rope is connected to the pulling piece, when the connecting rope is not connected to the embedded steel bars, there is a possibility that the pulling piece will be affected by the gravity and detach from the connecting sleeve, thereby reducing the time spent on re-threading the connecting rope through the through holes on the grouting pipe and the connecting sleeve.

[0021] Preferably, the positioning assembly also includes a plurality of fixing ropes connected to the lower end of the connecting rope and a positioning collar fixed to the fixing rope, the positioning collar has a plurality of barbed pieces spaced apart along its axis, and the barbed pieces are embedded in the threads on the embedded steel bars.

[0022] By adopting the above technical solution, a positioning ring is provided, and the barbs on the positioning ring are embedded in the threads on the embedded steel bars so as to connect the connecting rope to the embedded steel bars, thereby reducing the time required for tying the connecting rope and the embedded steel bars, speeding up the connection rate between the embedded steel bars, and thereby speeding up the subsequent installation rate of the prefabricated shear wall.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. By providing a positioning component, the relative position between the connecting sleeve and the embedded steel bar can be checked to reduce the time spent on aligning the connecting sleeve with the embedded steel bar below, that is, to increase the alignment rate between the connecting sleeve and the embedded steel bar, thereby increasing the installation rate of the assembled shear wall.

[0025] 2. Several connecting ropes are fixedly connected to a pulling rod, and the pulling rod is pulled to tighten the several connecting ropes, so that the relative positions between multiple connecting sleeves and embedded steel bars can be checked, so as to reduce the time spent on pulling several connecting ropes one by one.

[0026] 3. By providing a connecting rod and a pulley, the wear of the connecting rope can reduce the impact on the subsequent observation of the position between the connecting sleeve and the embedded steel bar, and also reduce the resistance encountered when pulling the connecting rope.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 , further details of this application are given.

[0035] The embodiment of the present application discloses an assembled shear wall structure for green building.

[0036] Example:

[0037] A prefabricated shear wall structure for green buildings, referring to Figure 1 , Figure 2, including a connecting sleeve 2 embedded in the shear wall 1 and a connecting steel bar 3 embedded in the wall and passing through the connecting sleeve 2, wherein the bottom wall of the connecting sleeve 2 is penetrated with a through hole 21 connected to the connecting sleeve 2, so as to allow the embedded steel bar 4 to slide through the through hole 21 to enter the connecting sleeve 2, the outer surface of the connecting sleeve 2 at the lower end is penetrated with a grouting pipe 22, and the outer surface of the connecting sleeve 2 at the upper end is penetrated with a grouting pipe 23, and the connecting sleeve 2 is provided with a sealing plug 24 for blocking the feed end of the grouting pipe 22 and the discharge end of the grouting pipe 23, and the sealing plug 24 is used to block the grouting material after grouting. It should be noted that a plurality of connecting sleeves 2 are arranged at intervals along the length direction of the shear wall 1, and the embedded steel bars 4 are embedded in the beam body or in the ground.

[0038] Reference Figure 2 , Figure 3 Furthermore, in order to facilitate checking the docking effect between the embedded steel bar 4 and the connecting sleeve 2, in this embodiment, a positioning assembly 5 for positioning the embedded steel bar 4 is provided on the connecting sleeve 2, and the positioning assembly 5 specifically includes a connecting rope 51 for connecting with the embedded steel bar 4, a connecting rod 52 passing through the grouting pipe 22, a pulley 53 rotatably connected to the connecting rod 52, and a pulling member 54 for pulling the connecting rope 51. Among them, the upper end of the connecting rope 51 passes through the through hole 21 and the grouting pipe 22, and extends to the outside of the shear wall 1, and the lower end of the connecting rope 51 is exposed at the lower end of the shear wall 1. In this embodiment, at least two connecting ropes 51 are provided, and the two connecting ropes 51 are respectively passed through the through holes 21 on two of the connecting sleeves 2 and the grouting pipe 22 provided on the connecting sleeve 2.

[0039] Among them, in this embodiment, the connecting rod 52 is set as a square rod, and a connecting piece 6 is provided on the connecting rod 52. The connecting rod 52 is detachably connected to the connecting sleeve 2 through the connecting piece 6. The connecting piece 6 specifically includes a blocking ring 61 sleeved on the connecting rod 52 and an elastic rubber pad 62 wrapped around the outer peripheral wall of the blocking ring 61, wherein the blocking ring 61 can be fixedly connected to the connecting rod 52 by a bolt 611, or the connecting rod 52 is slidably connected to the blocking ring 61, and then limited by a limiting member, which can also be a bolt. The connecting rod 52 is provided with a plurality of limiting holes for the bolts to pass through. Since this is a common method in the prior art, it will not be described in detail here. In this embodiment, the blocking ring 61 and the connecting rod 52 are fixedly connected by bolts 611, and the blocking ring 61 is slidably inserted into the grouting pipe 22, and the elastic rubber pad 62 abuts against the inner wall of the grouting pipe 22.

[0040] Among them, the connecting rope 51 is wound around the pulley 53. In this embodiment, the size of the pulley 53 is smaller than the inner diameter of the grouting pipe 22 so that it can enter the connecting sleeve 2 from the feed end of the grouting pipe 22. It should be noted that the connecting steel bar 3 is located above the connecting rod 52 to reduce the possibility of collision between the pulley 53 and the connecting steel bar 3.

[0041] The pulling member 54 is arranged outside the shear wall 1. In this embodiment, the pulling member 54 is a pulling block connected to the connecting rope 51. The connection between the two is that the connecting rope 51 is wound around the pulling block and tied, so that the connecting rope 51 is fixedly connected to the pulling block. In this embodiment, the number of pulling blocks is the same as the number of connecting ropes 51, and the size of the pulling block is larger than the outer diameter of the grouting pipe 22. In order to reduce the possibility that the connecting rope 51 connected to the pulling block slips and detaches from the connecting sleeve 2 due to the weight of the pulling block itself, in this embodiment, the connecting rod 52 is exposed to the sealing ring 61, and the pulling block abuts against the upper surface of the connecting rod 52.

[0042] The implementation principle of the prefabricated shear wall structure for green buildings in the embodiment of the present application is as follows: after lifting the shear wall 1, the connecting rope 51 is then connected to the embedded steel bars 4. After the connection, the wall is brought close to the embedded steel bars 4, and the connecting rope 51 is pulled by the pulling member 54 to make the connecting rope 51 taut. By observing the position of the connecting rope 51, the relative position between the connecting sleeve 2 and the embedded steel bars 4 can be checked to reduce the time spent on aligning the connecting sleeve 2 with the embedded steel bars 4 below, that is, to increase the alignment rate between the connecting sleeve 2 and the embedded steel bars 4, thereby increasing the installation rate of the prefabricated shear wall 1.

[0043] Embodiment 2:

[0044] Reference Figure 4 The difference from Example 1 is that the pulling member 54 is a pulling rod fixedly connected to the connecting rope 51, the length direction of the pulling rod is parallel to the length direction of the shear wall 1, and several connecting ropes 51 are fixedly connected to one pulling rod to reduce the time spent on pulling several connecting ropes 51 one by one.

[0045] Embodiment 3:

[0046] Reference Figure 5 , Figure 6, which is different from Example 1, is that, in this embodiment, the positioning assembly 5 also includes a plurality of fixing ropes 55 connected to the lower end of the connecting rope 51 and a positioning collar 56 fixed to the fixing rope 55. It should be noted that at least two fixing ropes 55 are provided, and the positioning collar 56 has a plurality of barbed pieces 561 spaced apart along its axis. At least two barbed pieces 561 are provided, and pressure is applied to the barbed pieces 561 so that the barbed pieces 561 are embedded in the threads on the embedded steel bars 4, thereby realizing the relative setting between the positioning collar 56 and the connecting rope 51.
