[0060] Structural embodiment 1

[0061] Referring to Figures 1-7 , the embodiment provides a prefabricated elevator shaft standard section, which comprises at least two elevator side wall plates 1, an elevator door plate 2, an elevator rear wall plate 3 and a corridor plate 4. The two elevator side wall plates 1 are arranged side by side with a spacing, the elevator side wall plate 1 is provided with a first side wall connecting vertical groove 101 at the elevator door position, and the elevator side wall plate 1 is provided with a second side wall connecting vertical groove 102 at the rear wall position; the two sides of the elevator door plate 2 are provided with a first door plate connecting vertical groove 201, the elevator door plate 2 is located between the two elevator side wall plates 1, and the first door plate connecting vertical grooves 201 on the two sides of the elevator door plate 2 form a first cast-in-place space 200 with the first side wall connecting vertical grooves 101, respectively, and the first cast-in-place space 200 is arranged with a first cast-in-place structural rib 11; the two sides of the elevator rear wall plate 3 are provided with a first rear wall connecting vertical groove 301, the elevator rear wall plate 3 is located between the two elevator side wall plates 1, and the first rear wall connecting vertical grooves 301 on the two sides of the elevator rear wall plate 3 form a second cast-in-place space 300 with the second side wall connecting vertical grooves 102, respectively, and the second cast-in-place space 300 is arranged with a second cast-in-place structural rib 12; the corridor plate 4 is laid on the elevator side wall plate 1.

[0062] As known, the elevator structure added to the existing building comprises a shaft and a corridor, the shaft is used for installing the elevator, and the corridor is used for connecting the existing building. As described above, the space formed between the two elevator side wall plates 1 is divided into a shaft space 1b and a corridor space 1a by the elevator door plate 2, and the shaft space 1b is formed between the elevator rear wall plate 3 and the elevator door plate 2.

[0063] The elevator side wall plate 1:

[0064] Referring to Figure 3 , the elevator side wall plate 1 is prefabricated in the factory, and the first side wall connecting vertical groove 101 and the second side wall connecting vertical groove 102 are formed at the joint of the elevator door plate 2 and the elevator rear wall plate 3 through a mold, which is a vertical groove with an open side for subsequent post-pouring (construction of cast-in-place) after splicing the elevator door plate 2 and the elevator rear wall plate 3.

[0065] Further, referring to Figure 3 , in combination with Figure 5 and Figure 7 , the preset parts of the first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 are arranged in advance in the first side wall connecting vertical groove 101 and the second side wall connecting vertical groove 102. It should be noted that this is a preferred embodiment of the embodiment, and as another embodiment, the first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 can also be arranged in the first door plate connecting vertical groove 201 and the first rear wall connecting vertical groove 301, respectively.

[0066] In detail, in combination withFigure 2 、 Figure 3 、 Figure 9 and Figure 12 , the first cast-in-place structure bar 11 includes a first pivot joint bar 111, a first connecting bar 112, a first horizontal limiting bar 114, a first longitudinal limiting member 113 and a first structure longitudinal bar 115. First, the first pivot joint bar 111 is arranged in the first side wall connecting vertical groove 101, and a plurality of continuous interval arrangements are arranged along the length direction of the groove, the purpose is to install the first connecting bar 112, and the first connecting bar 112 is preferably implemented as a ring buckle stirrup, so interval arrangement according to the stirrup arrangement standard of the reinforcement cage can be carried out. The first horizontal limiting bar 114 is located on one side of the first pivot joint bar 111, and is used for horizontally overturning and resting the first connecting bar 112, and the first horizontal limiting bar 114 can be arranged in the first side wall connecting vertical groove 101 or the first door plate connecting vertical groove 201 opposite the position after splicing, the number of which corresponds to the number of the first connecting bar 112, and is used for providing a carrier for transversely resting the first connecting bar 112 in cooperation with the first pivot joint bar 111.

[0067] Please refer to Figure 3, the first connecting rib is pivoted to the first pivot rib 111, and the pivot point is lower than the center of gravity of the first connecting rib; and in at least the vertical direction, the first connecting rib 112 has a tendency to horizontally fall over due to the center of gravity deviating from the pivot point. Specifically, the first connecting rib 112 is preferably a looped rib, and in pre-installation, the first connecting rib 112 should be arranged on the first pivot rib 111 to maintain a vertical state and not protrude from the slot (the first side wall connecting vertical slot 101 or the first door plate connecting vertical slot 201, depending on which slot it is installed in). Specifically, a circular ring is formed at a position halfway down the first connecting rib 112, which is sleeved on the first pivot rib 111 to enable it to rotate around the first pivot rib 111. Therefore, the self-weight of the upper part of the pivot point of the looped rib structure of the first connecting rib 112 is large, and it is easy to fall over and rest in a horizontal state towards the first horizontal limiting rib 114. The first horizontal limiting rib 114 is located on one side of the first pivot rib 111 and provides a horizontal falling over resting place for the first connecting rib 112. In order to maintain the vertical state of the first connecting rib 112 in pre-installation (pre-cast installation), the first longitudinal limiting member 113 is detachably arranged in the first cast-in-place space 200 and limits the first connecting rib 112 to maintain a vertical state. Preferably, the first longitudinal limiting member 113 is selected from a rope-like, rod-like, strip-like, or elastic tensile limiting member that limits the looped rib to maintain a vertical state. In this embodiment, as a preferred embodiment, the first longitudinal limiting member 113 is selected as a rubber band. The looped rib is originally all standing, and it is straightened by the rubber band. In the cast-in-place process, it is pulled to a horizontal state. Specifically, in this embodiment, the pivot point is taken as the position standard, and the lower part of the adjacent looped rib with a relatively small self-weight is connected in sequence by the rubber band and kept in a straight pre-stressed state. The upper part of the looped rib with a relatively large self-weight should be located on the front side of the rubber band (i.e., the side facing the first horizontal limiting rib 114), because it prevents the looped rib from falling over in the opposite direction of the first horizontal limiting rib 114, and it provides another limiting member, such as a plug rod (not shown in the figure), on the side of the looped rib facing the first horizontal limiting rib 114 to prevent the looped rib from falling over in advance. In the cast-in-place process, only the plug rod needs to be pulled out, and the top looped rib is tilted towards the first horizontal limiting rib 114. The lower part of the looped rib is pulled up by the rubber band, forming a chain effect to tilt and rest each looped rib on the first horizontal limiting rib 114, and the two ends of the looped rib are respectively extended in the first side wall connecting vertical slot 101 and the first door plate connecting vertical slot 201. Finally, at least two first structure longitudinal ribs 115 are respectively vertically inserted into the first side wall connecting vertical slot 101 and the first door plate connecting vertical slot 201 to form a steel cage structure (including stirrups and longitudinal ribs).

[0068] It should be noted that the first longitudinal limiting member 113 is selected as a rubber band only as a more economical implementation, and is not the only limitation; it can also be used as a connecting rod, such as connecting the two ends of the connecting rod through a ring to the adjacent ring buckle, and the lower part of the lighter self-weight can also achieve this effect.

[0069] Similarly, as above, please combine Figure 2 , Figure 3 , Figure 9 and Figure 12 , the structure and function of the second cast-in-place structure 12 are equivalent to the first cast-in-place structure 11, and the difference is to connect the elevator rear wall plate 3 and the elevator side wall plate 1. The second cast-in-place structure 12 includes a second pivot joint 121, a second connecting rod 122, a second horizontal limiting rod 124, a second longitudinal limiting member and a second structural longitudinal rod 125. Therefore, preferably, the second pivot joint 121 is provided in the second side wall connecting vertical groove 102, and the second horizontal limiting rod 124 is provided in the first rear wall connecting vertical groove 301; the second longitudinal limiting member is also preferably a rubber band, and its connection method is equivalent to the first longitudinal limiting member 113, which will not be repeated here, and those skilled in the art can know it; At least two second structural longitudinal rods 125 are respectively vertically inserted into the second side wall connecting vertical groove 102 and the first rear wall connecting vertical groove 301 to form a steel cage structure (including stirrups and longitudinal rods).

[0070] Further, please refer to Figure 11 , the standard section provided by the embodiment is connected by layering through pouring; therefore, when the adjacent standard sections are installed, the first structural longitudinal rod 115 of the two is connected through the second adapter 2002, so that the second hand hole 20 is provided at the connection position of the two first cast-in-place pouring spaces 200, to facilitate manual connection of the first structural longitudinal rod 115 using the second adapter 2002. The position of the second hand hole can be provided in the elevator side wall plate 1 or the elevator door plate 2, aiming to realize connection as the main.

[0071] Similarly, please refer to Figure 11 , the second structural longitudinal rod 125 of the two is connected through the third adapter 3002, so that the third hand hole 30 is provided at the connection position of the two second cast-in-place pouring spaces 300, to facilitate manual connection of the second structural longitudinal rod 125 using the third adapter 3002. The position of the third hand hole can be provided in the elevator side wall plate 1 or the elevator door plate 2, aiming to realize connection as the main.

[0072] Further, please combine Figure 5 and Figure 10In order to realize the equivalent cast-in-place structural strength, several reinforcing column structures can be additionally arranged at the standard corners or vertical load bearing positions. Specifically, the cast-in-place through-pouring column groove 100 is formed at the corners of the corridor space 1a or the shaft space 1b corresponding to the positions of the elevator side wall panel 1, and the column bar 1001 is arranged in the cast-in-place through-pouring column groove 100 to form the reinforcing column structure after casting. As shown in the figure, four reinforcing column structures are arranged on each elevator side wall panel 1, which are respectively arranged at the two sides of the elevator door panel 2 joint and the front and back sides of the elevator side wall panel 1, so as to strengthen the overall structural strength. Similarly, the column bars 1001 of adjacent standard sections can also be connected through the first connector 1002, and therefore the first hand hole 10 is arranged at the connection position of the column bar 1001 on the elevator side wall panel 1 to facilitate manual connection.

[0073] The elevator door panel 2 is arranged on the elevator side wall panel 1 and is connected to the elevator side wall panel 1 through the first door panel connecting vertical groove 201 and the first door panel connecting horizontal groove 202.

[0074] Please refer to Figure 2 and Figure 5 The first door panel connecting vertical groove 201 is arranged on the two sides of the elevator door panel 2. As described above, the first connecting bar 112, the first pivot connecting bar 111 and the first horizontal limiting bar 114 of the first cast-in-place structural bar 11 can also be arranged in the first door panel connecting vertical groove 201. However, as a preferred embodiment of the present embodiment, the first horizontal limiting bar 114 is arranged in the first door panel connecting vertical groove 201 and is arranged at intervals along the length direction of the groove, and the position and number of the first horizontal limiting bar 114 correspond to the first pivot connecting bar 111 to realize the horizontal placement of the first connecting bar 112 in cooperation with the first pivot connecting bar 111.

[0075] The second hand hole 20 is arranged at the bottom of the elevator door panel 2, and the position of the second hand hole 20 corresponds to the first door panel connecting vertical groove 201 to facilitate the connection of the first structural longitudinal bar 115 with the adjacent standard section.

[0076] It should be noted that the elevator door hole is also arranged in the elevator door panel 2, which is well known and will not be described here.

[0077] The elevator rear wall panel 3 is arranged on the elevator side wall panel 1 and is connected to the elevator side wall panel 1 through the first rear wall connecting vertical groove 301 and the first rear wall connecting horizontal groove 302.

[0078] Please refer to Figure 4 and Figure 7 The first rear wall connecting vertical groove 301 is arranged on the two sides of the elevator rear wall panel 3. As described above, the second connecting bar 122, the second pivot connecting bar 121 and the second horizontal limiting bar 124 of the second cast-in-place structural bar 12 can also be arranged in the first rear wall connecting vertical groove 301. However, as a preferred embodiment of the present embodiment, the second horizontal limiting bar 124 is arranged in the first rear wall connecting vertical groove 301 and is arranged at intervals along the length direction of the groove, and the position and number of the second horizontal limiting bar 124 correspond to the second pivot connecting bar 121 to realize the horizontal placement of the second connecting bar 122 in cooperation with the second pivot connecting bar 121.

[0081] Please refer to Figure 1 , Figure 5 and Figure 6 , the corridor panel 4 is provided to provide a corridor passage in cooperation with the corridor space 1a, and the corridor panel 4 in the embodiment is a prefabricated panel. A lap joint reinforcement 41 is arranged at the corner of the corridor panel 4, and the lap joint reinforcement 41 is integrally connected by being cast in the cast-in-place column slot 100. Preferably, the lap joint reinforcement 41 is implemented as a U-shaped reinforcement, and the column reinforcement 1001 is inserted into the U-shaped reinforcement. The lap joint effect of the elevator side wall panel 1 is formed by cast-in-place column slot 100 grouting, and the U-shaped reinforcement cooperates with the column reinforcement 1001 to form a steel reinforcement cage structure that strengthens the column structure.

[0082] The shaped support 6:

[0083] Please refer to Figure 1 , and in combination with Figures 5-6 , a plurality of shaped supports 6 are arranged at least at the joint corner of the elevator side wall panel 1 and the elevator door panel 2; and / or the joint corner of the elevator side wall panel 1 and the elevator rear wall panel 3; and / or the side of the elevator side wall panel 1 facing the corridor space 1a.

[0084] The shaped support 6 in the embodiment is implemented as an angle steel structure, which includes an angle steel and is reinforced by two triangular plates. The shaped support 6 has the following effects: on the one hand, it reinforces the structure before the cast-in-place of the elevator side wall panel 1, the elevator door panel 2 and the elevator rear wall panel 3; on the other hand, it temporarily supports the corridor panel 4; and on the other hand, when the temporary construction panel 5 needs to be supported in the shaft space 1b, it can also be used as a temporary support for the temporary construction panel 5.

[0085] Therefore, in the embodiment, angle steel structures are arranged at the joint corner of the elevator side wall panel 1 and the elevator rear wall panel 3, and are arranged in two layers respectively; similarly, angle steel structures are arranged at the joint corner of the elevator side wall panel 1 and the elevator door panel 2, and are arranged in two layers respectively; angle steel structures are arranged at the four corners of the corridor panel 4 in the corridor space 1a for supporting the corridor panel 4; and angle steel structures are arranged at the four corners of the temporary construction panel 5 in the shaft space 1b for supporting the temporary construction panel 5.

[0086] The beneficial effects of the embodiment are as follows:

[0087] The prefabricated standard section is divided into five plate bodies, i.e., a side wall plate, a door plate, a rear wall plate and a corridor plate 4 of the elevator. The prefabricated standard section can be cast horizontally in a factory, and the original equipment of the factory can be used for mass production. Moreover, the whole standard section is divided into five parts, and hoisting and transportation are convenient.

[0088] The first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 are connected by a connecting rib, which is kept vertical and does not protrude from the groove during installation, facilitating the installation of the side wall plate, the door plate and the rear wall plate. Then, the connecting rib is placed horizontally in a vertical state, and the two ends are respectively extended between the first door plate connecting vertical groove 201 and the first side wall connecting vertical groove 101 and between the first rear wall connecting vertical groove 301 and the second side wall connecting vertical groove 102. Moreover, the first and second connecting ribs 122 are ring buckling ribs, so that the structural ribs in the first cast-in-place pouring space 200 and the second cast-in-place pouring space 300 include longitudinal ribs and hoop ribs, and the strength is equivalent to that of cast-in-place.

[0089] Before the concrete is poured or before the grouting material is poured, the connecting corner of each component is supported by a shaped support 6 (which can be implemented as an angle steel), so that the entire component remains stable. This fixing is equivalent to temporarily forming a whole, facilitating the one-time pouring of the stacked standard sections, and improving the installation efficiency.

[0090] At the position corresponding to the connection between the first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 in each standard section, a hand hole is provided to facilitate the connection of the steel bars. In this way, the inconvenience of using a whole steel bar for the longitudinal rib is avoided. Similarly, a hand hole is also provided at the connection of the column rib 1001 in the cast-in-place pouring column groove 100.

[0091] Structural embodiment 2:

[0092] Please refer to Figure 8 , and in combination with Figures 1-7 , the embodiment provides a block prefabricated elevator shaft standard section, which includes a plurality of block prefabricated elevator shaft standard sections provided by the structural embodiment 1. The plurality of standard sections are connected and formed by pouring through the first cast-in-place pouring space 200 and the second cast-in-place pouring space 300. Further, the plurality of standard sections are also connected by cast-in-place pouring through the cast-in-place pouring column groove 100.

[0094] As known, the existing building elevator installation structure includes a hoistway and a corridor, the hoistway is used for installing the elevator, and the corridor is used for connecting the existing building. As described above, the space formed between the two elevator side wall panels 1 is divided into a hoistway space 1b and a corridor space 1a by the elevator door panel 2, and the hoistway space 1b is formed between the elevator rear wall panel 3 and the elevator door panel 2.

[0095] The elevator side wall panel 1:

[0096] Please refer to Figure 3 , the elevator side wall panel 1 is preformed in the factory, the first side wall connecting vertical groove 101 and the second side wall connecting vertical groove 102 are formed at the joint of the elevator door panel 2 and the elevator rear wall panel 3 through a mold, and the groove is a vertical groove with an open side, which is used for subsequent post-pouring (construction cast-in-place) after splicing the elevator door panel 2 and the elevator rear wall panel 3.

[0097] Further, please refer to Figure 3 in combination with Figure 5 and Figure 7 , the preset part of the first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 is arranged in advance in the first side wall connecting vertical groove 101 and the second side wall connecting vertical groove 102. It should be pointed out that this is a preferred embodiment of the present embodiment, and as another embodiment, the preset part of the first cast-in-place structural rib 11 and the second cast-in-place structural rib 12 can also be arranged in the first door panel connecting vertical groove 201 and the first rear wall connecting vertical groove 301 respectively.

[0098] Specifically, please refer to Figure 2 , Figure 3 , Figure 9 and Figure 12, the first cast-in-place structure rib 11 includes a first pivot connecting rib 111, a first connecting rib 112, a first horizontal limiting rib 114, a first longitudinal limiting member 113 and a first structure longitudinal rib 115. First, the first pivot connecting rib 111 is arranged in the first side wall connecting vertical groove 101, and a plurality of continuous interval settings are arranged along the length direction of the groove, and the purpose is to install the first connecting rib 112, and the first connecting rib 112 is preferably implemented as a ring buckle stirrup, so interval setting according to the stirrup arrangement standard of the reinforcement cage can be carried out. The first horizontal limiting rib 114 is located on one side of the first pivot connecting rib 111, and is used for horizontally overturning and placing the first connecting rib 112, and here the first horizontal limiting rib 114 can be arranged in the first side wall connecting vertical groove 101, or can be arranged in the first door plate connecting vertical groove 201 opposite the position after splicing, the number of which corresponds to the number of the first connecting rib 112, and is used to cooperate with the first pivot connecting rib 111 to provide a carrier for transversely placing the first connecting rib 112.

[0099] Please refer to Figure 3, the first connecting rib is pivoted to the first pivot rib 111, and the pivot point is lower than the center of gravity of the first connecting rib; and in at least the vertical direction, the first connecting rib 112 has a tendency to horizontally fall over due to the center of gravity deviating from the pivot point. Specifically, the first connecting rib 112 is preferably a looped rib, and in pre-installation, the first connecting rib 112 should be arranged on the first pivot rib 111 to maintain a vertical state and not protrude from the slot (the first side wall connecting vertical slot 101 or the first door plate connecting vertical slot 201, depending on which slot it is installed in). Specifically, a circular ring is formed at a position halfway down the first connecting rib 112, which is sleeved on the first pivot rib 111 to enable it to rotate around the first pivot rib 111. Therefore, the self-weight of the upper part of the pivot point of the looped rib structure of the first connecting rib 112 is large, and it is easy to fall over and rest in a horizontal state towards the first horizontal limiting rib 114. The first horizontal limiting rib 114 is located on one side of the first pivot rib 111 and provides a horizontal falling over resting place for the first connecting rib 112. In order to maintain the vertical state of the first connecting rib 112 in pre-installation (pre-cast installation), the first longitudinal limiting member 113 is detachably arranged in the first cast-in-place space 200 and limits the first connecting rib 112 to maintain a vertical state. Preferably, the first longitudinal limiting member 113 is selected from a rope-like, rod-like, strip-like, or elastic tensile limiting member that limits the looped rib to maintain a vertical state. In this embodiment, as a preferred embodiment, the first longitudinal limiting member 113 is selected as a rubber band. The looped rib is originally all standing, and it is straightened by the rubber band. In the cast-in-place process, it is pulled to a horizontal state. Specifically, in this embodiment, the pivot point is used as the position standard, and the lower part of the adjacent looped rib with a relatively small self-weight is connected in sequence by the rubber band and kept in a straight pre-stressed state. The upper part of the looped rib with a relatively large self-weight should be located on the front side of the rubber band (i.e., the side facing the first horizontal limiting rib 114), because it prevents the looped rib from falling over in the opposite direction of the first horizontal limiting rib 114, and it provides another limiting member, such as a plug rod (not shown in the figure), on the side of the looped rib facing the first horizontal limiting rib 114 to prevent the looped rib from falling over in advance. In the cast-in-place process, only the plug rod needs to be pulled out, and the top looped rib is tilted towards the first horizontal limiting rib 114. The lower part of the looped rib is pulled up by the rubber band, forming a chain effect to tilt and rest each looped rib on the first horizontal limiting rib 114, and the two ends of the looped rib extend in the first side wall connecting vertical slot 101 and the first door plate connecting vertical slot 201, respectively. Finally, at least two first structure longitudinal ribs 115 are vertically inserted into the first side wall connecting vertical slot 101 and the first door plate connecting vertical slot 201, respectively, to form a steel cage structure (including stirrups and longitudinal ribs).

[0100] It should be noted that the first longitudinal limiting member 113 is selected as a rubber band only as a more economical implementation, and is not the only limitation; it can also be used as a connecting rod, such as connecting the two ends of the connecting rod through a ring to the adjacent ring buckle, and the lower part of the lighter self-weight can also achieve this effect.
