Referring to fig. 1, an embodiment of the present application provides an elevator hoistway structure 100. The elevator hoistway structure 100 includes a pit 110, a hoistway frame 120, and a fender member 130.
The pit 110 is disposed below the ground.
Specifically, the top of the pit 110 is located 20cm to 30cm below the ground.
Referring to fig. 3 to 6, the hoistway frame 120 includes at least four steel columns 121 parallel to each other. At least four steel columns 121 extend along the vertical direction respectively and arrange in proper order along the circumference of well. The bottom of the steel columns 121 are located below the ground and are fixedly connected to the top of the pit 110. The top of the steel columns 121 extend above the ground.
Specifically, in the present embodiment, the hoistway frame 120 includes four steel columns 121 that are parallel to each other and extend in the vertical direction, respectively. Four steel columns 121 are arranged in sequence along the circumferential direction of the hoistway. Referring to fig. 1, 4-6, the hoistway frame 120 further includes a plurality of cross members 122. Each cross beam 122 connects two adjacent steel columns 121. The cross-section of the hoistway frame 120 forms a substantially rectangular shape. Four steel columns 121 form the four corners of a rectangle. The internal space enclosed by the four steel columns 121 and the plurality of cross beams 122 forms the internal space of the hoistway frame 120.
In the present embodiment, the pit 110 is cast of reinforced concrete. The bottom of the steel column 121 is welded with a pre-buried steel plate (not shown) at the top of the pit 110, so that the steel column 121 is fixedly connected with the top of the pit 110. Since the bottom of the steel columns 121 are below the ground, the junction of the bottom of the steel columns 121 and the top of the pit 110 is below the ground. The top of the steel columns 121 extend above the ground.
Referring to fig. 1, 2 and 4 to 6, the fender component 130 includes a first fender segment 131 and a second fender segment 132. The first guard plate section 131 is surrounded at the periphery of the connection between the four steel columns 121 and the pit 110. The second guard plate section 132 surrounds the four steel columns 121. One end of the second guard plate segment 132 is hermetically connected with the first guard plate segment 131, and the other end extends to above the ground.
Specifically, the material used for the apron member 130 is a concrete material, such as an ultra high performance concrete material. Connectors 132a may be pre-embedded within the second fender section 132 when the fender components 130 are poured. The connecting member 132a may be, for example, a pre-buried bolt. The second fender section 132 is fixedly connected to the steel column 121 through the connecting member 132a, so that the fender member 130 is fixedly connected to the steel column 121.
Because the first protection plate section 131 is arranged around the periphery of the connection part of the four steel columns 121 and the pit 110, the first protection plate section 131 shields the connection part of the four steel columns 121 and the pit 110, and the second protection plate section 132 is connected with the first protection plate section 131 in a sealing manner, the second protection plate section 132 is arranged around the periphery of the four steel columns 121, the second protection plate section 132 extends out of the ground, so that rainwater on the ground can be prevented from flowing into the pit 110 and the well frame 120 from the second protection plate section 132, the connection part of the second protection plate section 132 and the first protection plate section 131, and a good waterproof effect is achieved.
Further, the portion of the second guard plate segment 132 protruding to the ground may protect the ground-near portion of the elevator hoistway structure 100, preventing the enclosure material of the ground-near portion of the elevator hoistway structure 100 from being damaged by accidental impacts.
Specifically, the other end of the second guard plate segment 132 extends to a height of 0.8-1 m above the ground, for example, a height of 0.8 m, 0.9 m, 1 m, and the like, so that the enclosure material of the elevator shaft structure 100 at a height of 0.8-1 m above the ground can be prevented from being damaged by accidental impact.
Because the connection between the bottom of the steel column 121 and the top of the pit 110 is located below the ground, one end of the first guard plate section 131 and the second guard plate section 132 is located below the ground, so that the connection between the bottom of the steel column 121 and the top of the pit 110 does not occupy the space above the ground, and the floor area of the elevator hoistway structure 100 above the ground and close to the ground can be reduced while the elevator hoistway structure 100 achieves the waterproof and anti-collision effects.
In this embodiment, the elevator hoistway structure 100 is attached to an exterior facade of a building. Since the cross-section of the hoistway frame 120 is substantially rectangular, the hoistway frame 120 has four outer sides. One of the outer sides of the hoistway frame 120 is opposite to the outer vertical surface of the building with a certain gap. One side of the outer side surface is used for installing an elevator door, and the shaft can directly lead to the interior of the building when the elevator door is opened, so that the outer side surface is in an indoor or semi-indoor environment, and a rainproof design or an anti-collision design is not needed. The other three outer sides of the hoistway frame 120 are exposed to the building, so that the second guard plate section 132 only needs to surround the four steel columns 121 along the other three outer sides, that is, the second guard plate section 132 partially surrounds the four steel columns 121.
In the elevator hoistway structure 100, the first guard plate section 131 is arranged around the periphery of the joint of the four steel columns 121 and the pit 110, so that the first guard plate section 131 shields the joint of the four steel columns 121 and the pit 110, and the second guard plate section 132 is connected with the first guard plate section 131 in a sealing manner, the second guard plate section 132 is arranged around the periphery of the four steel columns 121, and the second guard plate section 132 extends out of the ground, so that rainwater on the ground can be prevented from flowing to the pit 110 and the hoistway frame 120 from the second guard plate section 132, the joint of the second guard plate section 132 and the first guard plate section 131, and a good waterproof effect is achieved. The portion of the second guard plate segment 132 protruding to the ground may protect the near-ground portion of the elevator hoistway structure 100, preventing the containment material of the near-ground portion of the elevator hoistway structure 100 from being damaged by accidental impacts. Because the connection between the bottom of the steel column 121 and the top of the pit 110 is located below the ground, one end of the first guard plate section 131 and the second guard plate section 132 is located below the ground, so that the connection between the bottom of the steel column 121 and the top of the pit 110 does not occupy the space above the ground, and the floor area of the elevator hoistway structure 100 above the ground and close to the ground can be reduced while the elevator hoistway structure 100 achieves the waterproof and anti-collision effects.
Referring to fig. 4, in an embodiment, the second guard plate 132 is tightly attached to the outer vertical surfaces of the four steel columns 121, so that the floor area of the second guard plate 132 above the ground can be reduced.
Referring to fig. 1, 2 and 4-6, in an embodiment, the elevator shaft structure 100 further includes a third protection plate section 133. The third prevention plate section 133 is provided around the periphery of the pit 110. The third protection plate section 133 is connected to the first protection plate section 131 in a sealing manner.
Specifically, the first protection plate section 131 is located between the second protection plate section 132 and the third protection plate section 133, and is respectively connected with the second protection plate section 132 and the third protection plate section 133 in a sealing manner, so that the first protection plate section 131 and the third protection plate section 133 can be covered on the connection position of the steel column 121 and the top of the pit 110, tight shielding is further formed on the connection position of the steel column 121 and the top of the pit 110, and rainwater is further effectively prevented from entering.
Referring to fig. 4, in an embodiment, the third protection plate 133 is tightly attached to the outer surface of the pit 110 to reduce the space occupied by the third protection plate 133.
In one embodiment, the first guard plate segment 131, the second guard plate segment 132, and the third guard plate segment 133 are integrally formed.
Specifically, the material used for the apron member 130 is a concrete material. The first guard plate section 131, the second guard plate section 132 and the third guard plate section 133 are integrally cast.
In one embodiment, the material used for the fender components 130 is ultra high performance concrete.
In particular, ultra-high performance concrete is a novel material, has the characteristics of good ductility, high strength and strong impermeability, and is particularly suitable for being used as a thin-wall structure. The ultra-high performance concrete is poured into the guard plate member 130, so that the second guard plate section 132 and the third guard plate section 133 can be of a thin-wall structure, the second guard plate section 132 is tightly attached to the outer vertical surfaces of the four steel columns 121, and the third guard plate section 133 is tightly attached to the outer vertical surface of the pit 110, so that the floor area of the second guard plate section 132 above the ground and the space occupied by the third guard plate section 133 are saved.
Referring to fig. 2 in conjunction with fig. 1, in an embodiment, the protection plate member 130 includes a plurality of protection plates 130a, and the plurality of protection plates 130a are sequentially connected along a circumferential direction of the hoistway frame 120. The plurality of guard plates 130a are integrally formed or individually formed and then spliced.
Specifically, the number of the shielding plates 130a is three. The three guard plates 130a correspond to three outer side surfaces of the hoistway frame 120 one by one. Each protection plate 130a is fixedly connected with the corresponding steel column 121 on the outer side surface. The three guard plates 130a are sequentially connected around three outer sides of the hoistway frame 120. The three protection plates 130a may be integrally cast.
In other embodiments, the three protection plates 130a may be respectively and separately cast. The three protection plates 130a correspond to the three outer side surfaces of the hoistway frame 120 one by one, and after each protection plate 130a is fixedly connected with the steel columns 121 on the corresponding outer side surface, the three protection plates 130a are spliced into the protection plate member 130.
Referring to fig. 1 and 5, in one embodiment, the elevator hoistway structure 100 further includes an exterior wall envelope 140. The exterior wall enclosure 140 is located above the fender member 130 and is enclosed around the four steel columns 121.
Specifically, the exterior wall envelope 140 may be glass or other sheet material. In this embodiment, the exterior wall envelope 140 is glass. The outer wall envelope 140 may be fixedly attached to the beam 122 by means of glass claws 141. The outer wall enclosure 140 is fixed on the cross beam 122, and the operation is simple and convenient.
