Description

Technical Field

[0001] The utility model relates to an elevator shaft side wall structure for fixing elevator guide rails, belonging to the technical field of building structures. Background Art

[0002] For concrete frame structures, traditional elevator guide rails are generally fixed on the ring beam of the elevator shaft side wall, and the ring beam is located in the middle of the floor. Before the elevator is installed, the lower half of the elevator shaft side wall should be built first, and then the concrete ring beam should be poured on the top of the lower half of the elevator shaft side wall. After the strength of the ring beam reaches the design requirements, the upper half of the elevator shaft side wall is built on the ring beam. After the overall construction of the ring beam and the elevator shaft side wall is completed, the elevator guide rails can be installed and fixed on the ring beam to complete the installation of the elevator guide rails. The traditional elevator shaft side wall used to fix the elevator guide rails needs to be constructed in a time series sequence and step by step during the construction, resulting in a long construction period. Moreover, the installation of the elevator guide rails needs to wait until the elevator shaft side wall is completed before implementation. At the same time, the elevator guide rails have fewer connection points with the ring beam in the length direction. Utility Model Content

[0003] The purpose of the utility model is to provide an elevator shaft side wall structure for fixing elevator guide rails, so as to simplify the construction process and make the construction process more convenient. The installation of elevator guide rails and the masonry of the elevator shaft side wall can be constructed in parallel without affecting each other, thus effectively shortening the construction period.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An elevator shaft side wall structure for fixing elevator guide rails comprises a plurality of structural columns made of reinforced concrete, wherein the plurality of structural columns are arranged at the periphery of the elevator shaft between floors, a polystyrene board is arranged between the bottom of the structural column and the lower main structure, a groove is arranged between the bottom edge of the structural column and the lower main structure, and the groove surrounds the polystyrene board, and high-strength polymer cement mortar is filled in the groove, and the elevator guide rails are installed on the structural columns; a masonry wall is built at the periphery of the elevator shaft between floors, and the masonry wall and the structural columns together constitute the elevator shaft side wall.

[0006] As a preferred embodiment of the utility model, the polystyrene board is provided with reinforcement holes for the longitudinal reinforcement of the structural column to pass through, so as to facilitate the installation and positioning of the polystyrene board.

[0007] As a preferred embodiment of the present invention, the thickness of the polystyrene board is 25 mm, so as to ensure the flexible isolation effect between the structural column and the lower main structure and reduce the force influence of the structural column on the lower main structure.

[0008] As a preferred embodiment of the present invention, the structural columns and the upper main structure are cast in one step.

[0009] As a preferred embodiment of the present invention, the depth of the groove is 50 mm, so as to ensure the effectiveness of the high-strength polymer cement mortar in filling the groove.

[0010] As a preferred embodiment of the present invention, the strength of the high-strength polymer cement mortar is not less than 35 MPa, so as to ensure the equal strength connection between the bottom edge of the structural column and the lower main structure.

[0011] The utility model is beneficial in that:

[0012] The elevator guide rails are directly installed and fixed on the reinforced concrete structural columns. The structural columns and the main structure are cast at one time. The elevator guide rails can be installed after the strength of the structural columns reaches the requirements, which simplifies the construction process and makes the construction process more convenient.

[0013] Moreover, since the length direction of the elevator guide rail is consistent with that of the structural column, there are more points where the elevator guide rail can be connected to the structural column in the length direction;

[0014] At the same time, the side walls (masonry walls) of the elevator shaft other than the structural columns, as enclosing components, no longer bear the function of supporting the elevator guide rails, nor are they a prerequisite for the installation of the elevator guide rails. Therefore, they can be constructed separately or simultaneously with the elevator guide rails without affecting each other, thus effectively shortening the construction period.

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-5 As shown, the present embodiment is an elevator shaft side wall structure for fixing elevator guide rails, comprising a plurality of structural columns 1 made of reinforced concrete, wherein the plurality of structural columns 1 are arranged on the periphery of the elevator shaft between floors, and in the present embodiment, there are specifically four structural columns 1, a polystyrene board 2 is arranged between the bottom of the structural column 1 and the lower main structure 11, a groove 3 is arranged between the bottom edge of the structural column 1 and the lower main structure 11, and the groove 3 surrounds the polystyrene board 2, and a high-strength polymer cement mortar 4 is filled in the groove 3, and the elevator guide rails are installed on the structural columns 1; the elevator guide rails include car guide rails 5 and counterweight guide rails 6, wherein two structural columns 1 are used for installing the car guide rails 5, and the other two structural columns 1 are used for installing the counterweight guide rails 6; a masonry wall 7 is built on the periphery of the elevator shaft between floors, and the masonry wall 7 and the structural columns 1 together constitute the elevator shaft side wall; the masonry wall 7 can be a brick wall or an aerated block wall.

[0026] In this embodiment, the polystyrene board 2 is provided with a reinforcement hole 8 for the longitudinal reinforcement 10 of the structural column 1 to pass through, which is convenient for the installation and positioning of the polystyrene board 2. The thickness of the polystyrene board 2 is 25 mm, which is used to ensure the flexible isolation effect between the structural column 1 and the lower main structure 11, and reduce the force influence of the structural column 1 on the lower main structure 11.

[0027] In this embodiment, the longitudinal steel bars 10 of the structural column 1 are pre-embedded on the lower main structure 11; when the lower main structure 11 is cast, the bottom ends of the longitudinal steel bars 10 of the structural column 1 are directly anchored inside the lower main structure 11; when the upper main structure 12 is cast, the structural column 1 and the upper main structure 12 are cast and formed at one time.

[0028] In this embodiment, the depth of the slot 3 is 50 mm, which is used to ensure the effectiveness of the high-strength polymer cement mortar 4 in filling the slot 3. The strength of the high-strength polymer cement mortar 4 used is not less than 35 MPa, which is used to ensure that the bottom edge of the structural column 1 is connected with the lower main structure 11 with equal strength.

[0029] Before the pouring construction of the structural column 1, the longitudinal steel bars 10 of the structural column 1 are pre-embedded on the lower main structure 11; when pouring the structural column 1, the polystyrene board 2 is put on the longitudinal steel bars 10 of the structural column 1 through the steel bar holes 8, and finally placed at the bottom of the structural column 1. At this time, the cross-sectional size of the polystyrene board 2 is consistent with the cross-sectional size of the structural column 1, and then the steel bars of the structural column 1 and the upper main structure 12 are tied, and finally the mold is closed and concrete is poured, so that the structural column 1 and the upper main structure 12 are cast and formed at one time.

[0030] In this embodiment, reinforced concrete structural columns 1 are arranged around the elevator shaft between floors, and the cross-sectional dimensions of the structural columns 1 are 500x200mm; a 25mm thick polystyrene board 2 is arranged at the bottom of the structural column 1, and at this time, the cross-sectional dimensions of the polystyrene board 2 are consistent with the cross-sectional dimensions of the structural column 1, so that the structural column 1 is flexibly isolated from the lower main structure 11, and the force influence of the structural column 1 on the lower main structure 11 is reduced; the structural column 1 and the upper main structure 12 are cast at one time, and after the concrete strength reaches the design strength, the bottom edge of the structural column 1 is removed. A polystyrene board 2 is used to form a groove 3 with a size of 50x25mm, wherein 50mm is the depth of the groove 3, and a high-strength polymer cement mortar 4 is used to caulk and fill the groove 3, so that the bottom edge of the structural column 1 is connected to the lower main structure 11 with equal strength, and the strength of the high-strength polymer cement mortar 4 is not less than 35MPa; the elevator guide rail is fixed to the structural column 1 through the connector provided by the manufacturer; the elevator shaft side wall (masonry wall 7) other than the structural column 1 can be built later, or it can be built simultaneously with the elevator guide rail.

[0031] In the installation of traditional elevator guide rails, it is necessary to first build the side wall of the elevator shaft, and then cast a concrete ring beam for fixing the elevator guide rail at a half-story height. After the strength of the ring beam reaches the design requirements, the remaining side wall of the elevator shaft is built on the upper part of the ring beam. Finally, the ring beam and the side wall of the elevator shaft form a whole, and then the elevator guide rail is installed and fixed on the ring beam; while the elevator guide rail of this embodiment is directly installed and fixed on the reinforced concrete structural column, the structural column and the main structure are cast and formed at one time, and the elevator guide rail can be installed after the strength of the structural column reaches the requirements, which simplifies the construction process and makes the construction process more convenient; moreover, since the length direction of the elevator guide rail is consistent with that of the structural column, the elevator guide rail has more connection points with the structural column in the length direction; at the same time, the side wall of the elevator shaft (masonry wall) other than the structural column, as a protective component, no longer bears the role of supporting the elevator guide rail, and is no longer a prerequisite for the installation of the elevator guide rail, so it can be constructed separately or simultaneously with the elevator guide rail without affecting each other, effectively shortening the construction period.
