Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction method that combines the installation and masonry of passenger and freight elevators. Background Technology

[0002] In the construction of industrial and civil buildings, passenger and freight elevators are crucial equipment for vertical transportation. In traditional construction methods, the walls at the door openings of passenger and freight elevators on each floor are not constructed until the elevators are demolished. Only after the main structure is completed and the elevators are removed are the walls at the elevator door openings restored. During this period, the adjacent openings need to be kept sealed for an extended period, which not only takes up time for subsequent masonry work but also poses certain safety hazards, requiring daily safety inspections and maintenance, thus increasing construction management costs. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the construction of the wall at the door opening of the passenger and freight elevator is delayed in the existing construction method, which leads to the delay of the construction period and the long-term safety hazards of the adjacent opening.

[0004] To address the aforementioned technical problems, this invention provides a construction method that combines the installation and masonry of a passenger and freight elevator. This method involves pre-reserving a doorway and installing a lintel, then placing the elevator's safety door within the pre-reserved doorway to achieve simultaneous wall masonry and elevator installation. Specifically, the construction method includes the following steps: Based on the site layout and the parameters of the passenger and freight elevator, determine the installation location of the passenger and freight elevator and the reserved dimensions of the floor door openings; During the wall construction process, door openings are reserved at the floor door locations, and concrete lintels are poured above the door openings; Install a passenger and freight elevator and fix the safety door of the passenger and freight elevator in the reserved door opening; After the passenger and freight elevator is no longer in use, it shall be dismantled and the doorway shall be sealed and restored.

[0005] Preferably, when determining the installation location of the passenger and freight elevator and the reserved dimensions of the floor door openings, the determination is made based on the floor door installation location, the distance from the structural columns on both sides, and the door opening dimensions provided by the passenger and freight elevator manufacturer, thereby ensuring the matching accuracy between the reserved door openings and the passenger and freight elevator floor doors.

[0006] Preferably, the pouring of the concrete lintel is carried out simultaneously with the construction of the wall, so that the wall structure at the location of the passenger and freight elevator door opening is formed in one go, without the need for secondary construction later.

[0007] Preferably, when the safety door of the passenger and freight elevator is fixed in the reserved door opening, the gap between the safety door and the door opening is filled with sealing material to ensure the sealing and stability of the safety door after installation.

[0008] Preferably, when sealing and restoring the doorway, masonry or concrete of the same material as the wall is used for sealing, thereby ensuring the integrity and appearance consistency of the sealed wall with the original wall.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By reserving door openings in advance and setting lintels, the safety doors of passenger and freight elevators can be directly installed in the reserved door openings, so that the walls at the elevator door opening locations can be completed before the elevator is installed. This achieves simultaneous construction of wall masonry and elevator installation, significantly shortening the overall construction period. 2. The walls on both sides of the passenger and freight elevator door opening are built in advance, which can replace the traditional method of sealing and protecting the edge opening, eliminating the safety hazards of long-term edge work and improving construction safety. 3. It reduced the amount of secondary masonry reconstruction work after elevator demolition, lowered labor and material costs, and improved construction efficiency; 4. The concrete lintel is cast and formed simultaneously with the wall, ensuring good structural integrity at the doorway location and avoiding the impact of secondary construction on the wall quality.

[0013] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0014] like Figure 1 and Figure 2 As shown, this invention provides a construction method that combines the installation and masonry of a passenger and freight elevator, mainly including the following steps: Step 1: Determine the installation location of the passenger and freight elevator and the reserved dimensions of the doorway. Based on the construction site layout, plan in advance the installation location of the passenger and freight elevator 3. According to the technical parameters provided by the passenger and freight elevator manufacturer, determine the installation location of the floor doors, the distance between the floor doors and the structural columns on both sides, and the dimensions (length × height) of the door opening 6 to be reserved. The dimensions of the reserved door opening 6 should be slightly larger than the outer frame dimensions of the passenger and freight elevator floor doors to facilitate the installation and adjustment of the safety door 4, while also considering the installation gap between the door opening 6 and the safety door 4.

[0015] Step 2: Construct the wall and reserve the door opening, and pour the lintel. During the construction of the exterior wall 1 at the location of the elevator door, a doorway 6 is pre-reserved according to the dimensions determined in step one. A formwork is erected above the doorway 6, and a concrete lintel 2 is poured. The pouring of the concrete lintel 2 is carried out simultaneously with the construction of the exterior wall 1. The cross-sectional dimensions and reinforcement of the concrete lintel 2 are determined by structural calculations based on the width of the doorway 6 and the load on the upper wall, ensuring that the lintel 2 has sufficient load-bearing capacity. The exterior walls 1 on both sides of the doorway 6 are simultaneously constructed to the designed height, so that the elevator doorway location forms a complete wall structure before elevator installation.

[0016] Step 3: Install passenger and freight elevators and safety doors After the passenger and freight elevator 3 is installed in place, the safety door 4 of the passenger and freight elevator is fixed in the reserved doorway 6. The gap between the safety door 4 and the doorway 6 can be filled with sealing materials such as foaming agent or sealing strips to ensure the sealing and stability of the safety door 4 after installation, and to prevent rainwater leakage and air backflow. The bottom of the safety door 4 is smoothly connected to the protective passage 5 to ensure the safety of personnel and material transportation.

[0017] Step 4: Dismantle the passenger and freight elevator and seal the doorway. After the passenger and freight elevator 3 has been put into use and the main structure construction has been completed, the passenger and freight elevator 3 will be demolished. After demolition, the doorway 6 will be sealed and restored. The sealing material will be masonry or concrete of the same material as the exterior wall 1. The sealing construction will be carried out in accordance with the masonry construction specifications to ensure the integrity and appearance consistency between the sealed wall and the original exterior wall 1. After the sealing is completed, the surface of the exterior wall 1 at the location of the doorway 6 will be plastered and decorated according to the design requirements.

[0018] By using the above construction method, the wall construction at the location of the passenger and freight elevator doorway can be completed in advance before the elevator installation. The protective door 4 can be directly installed in the reserved doorway 6, eliminating the need to keep the edge opening blocked for a long time during the elevator's use. This shortens the construction period and improves construction safety.

[0019] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
