Description

Technical Field

[0001] The present application relates to the technical field of elevator door frames, and in particular to a processing and installation tool and a construction method for elevator door frames. Background Art

[0002] With the acceleration of urbanization, there are more and more high-rise buildings in cities. Elevators have become an indispensable living facility. As the core means of transportation for high-rise buildings, elevators provide convenience for people's daily lives. In construction, the installation efficiency of elevator door frames directly affects the construction period and economic cost. The installation of elevator door frames has always adopted traditional installation methods. Traditional elevator door frames are mostly cut, welded or screwed on site, which requires a lot of manual measurement and adjustment. In the process of installation and construction, wooden squares and large core boards are used as the base layer, and the decorative panels are fixed layer by layer with air nails and adhesives. The installation process involves multiple steps such as leveling, positioning, drilling, and fixing.

[0003] Traditional elevator door frames have the disadvantages of low modularity and poor adaptability, which are manifested in the following aspects: most traditional door frames are integral or semi-customized structures, with complicated processing steps, and require a lot of manual work to achieve door frame positioning and welding. The specifications of door frames during production are difficult to guarantee batch production, and there are large specification errors between finished products, which makes it frequent to cause misalignment problems due to uneven walls in actual construction, resulting in forced addition of adjustment steps during the installation process, causing damage to the decorative surface of the door frame or a decrease in flatness, making it difficult to adapt to the actual working conditions of the construction site, resulting in repeated operations and a high rework rate.

[0004] In summary, the low production and construction efficiency of elevator door frames is essentially due to the lack of modular rigid design in the production process of elevator door frames. Therefore, in view of the problems of the traditional elevator door frame production process, such as cumbersome process, reliance on a large number of manual positioning, difficulty in ensuring the specifications of the finished door frame, poor adaptability and complicated installation and construction process, a tool is designed to facilitate the rapid processing and installation of elevator door frames to improve the production and installation efficiency of elevator door frames, and at the same time, an efficient construction method for the tool in the construction of elevator door frames is proposed.

[0017] Furthermore, reinforcing ribs are provided at adjacent sides of the support frame, and a limiting block is provided on one side of the positioning rod.

[0018] Furthermore, the door cover mold frame and the installation mold frame are made of galvanized square pipes.

[0019] The present application also adopts the following technical solution: a method for constructing an elevator door frame, comprising the following steps:

[0020] S1. Door cover folding: The door cover is made of galvanized steel plate folding, and the door cover has three sections, namely two side edges and a top edge;

[0021] S2. Door cover positioning: install the door cover mold frame on the ground, then put the two sides of the door cover that have been folded into the door cover mold frame and connect them with the positioning rod;

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0045] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] In the traditional manufacturing process of elevator door frames, elevator door frames are manually connected and then welded by construction workers on site. Due to the size and weight of the elevator door frames, and the fact that the sides of the elevator door frames are often not at a completely vertical angle to their tops, the sides often have a certain angle of inclination, which leads to low efficiency of manual assistance in welding at a certain angle, and the accuracy of the joints is relatively poor, making it difficult to ensure that the sizes of the finished elevator door frames remain consistent. In response to the problems encountered when welding elevator door frames, the present application provides a mold that can quickly complete the positioning and welding of elevator door frames.

[0047] Embodiment 1:

[0048] like Figure 1-6 As shown, this embodiment provides a quick-assembly processing and installation tool for elevator door frames, including a door frame mold frame 100 and an installation mold frame 300:

[0049] The door cover mold frame 100 includes: a support frame 110, which extends in a horizontal direction and is suitable for supporting and fixing the door cover mold frame 100;

[0050] Positioning rods 200, at least one group of positioning rods 200 is provided, the positioning rods 200 are welded to one side of the support frame 110 at a certain angle, and the plane formed by the extension direction of each positioning rod 200 is perpendicular to the extension plane of the support frame 110; the positioning rods 200 are used to locate the inclination angle of the two sides of the elevator door frame;

[0051] The mounting formwork 300 includes: a vertical mounting frame 310, which is used to be fixed at the upper and lower ends of the elevator door; a horizontal mounting frame 320, which is fixedly connected to the middle of the vertical mounting frame 310 and is used to be fixed at the left and right ends of the elevator door; and a guide rail frame 330, which is vertically arranged at the upper end of the vertical mounting frame 310 to assist in the horizontal installation of the elevator door frame.

[0052] The door casing mold frame 100 further includes a movable positioning frame 400 , which is overlapped on the other side of the support frame 110 and is opposite to the positioning rod 200 .

[0053] The positioning rod 200 is welded to a frame of the support frame 110 by welding. The support frame 110 is rectangular. In order to ensure stability during use, reinforcing ribs 120 are welded at its four corners. The positioning rod 200 is mainly used to position the side of the door frame. The welding angle of the positioning rod 200 is consistent with the inclination angle of the side of the elevator door frame. Since the two sides of the door frame are respectively inclined inward at a certain angle, the positioning rods 200 are arranged opposite to each other. When welding the door frame, the sides of the two door frames can be placed against the positioning rods 200. At this time, the angle of the door frame is completely fixed, and the workers can efficiently complete the welding steps.

[0054] As a preferred embodiment, the cross-section of the positioning frame 400 is an isosceles trapezoid, and the bottom angle of the isosceles trapezoid is configured to be the same as the inclination angle of the positioning rod 200. Since the door frame has only two side edges and one top edge, when the side edges and the top edge of the door frame are welded, the other ends of the two side edges are in a positioning state. At this time, the positioning is completed by a movable bracket, which is an isosceles trapezoidal support frame 110. The inclination angles of the two side edges and the bottom are kept consistent with the inclination angle of the door frame. At this time, when the other end of the door frame has been fixed, the movable bracket is placed on the other side of the support frame 110, so that the oblique edge of its waist is against the door frame, thereby further ensuring the welding accuracy of the door frame.

[0055] As an optional implementation, we set positioning rods 200 with the same angle on two opposite sides of the support frame 110, and adopt the "fixed positioning rods 200 + movable positioning frame 400" combined positioning mode. At this time, you only need to place the door cover against the two positioning rods 200 to complete its fixed welding. However, if positioning rods 200 are set on both sides of the support frame 110, it is inconvenient to store the entire mold. Since the door cover mold frame 100 occupies a large area, it is usually placed sideways when not in use. When positioning rods 200 are set on both sides of the support frame 110, it is difficult to ensure that the positioning rods 200 will not touch the wall or other objects, thereby affecting its positioning accuracy.

[0056] The distance between the two relatively arranged positioning rods 200 can be set according to the actual width of the elevator door frame. In the present application, multiple positioning rods 200 with different intervals can be welded simultaneously on the side of the support frame 110 to adapt to the welding work of elevator door frames of various widths.

[0057] As a preferred embodiment, the positioning rod 200 is at an angle of 81° to one side of the support frame 110, the bottom angle of the positioning frame 400 is at an angle of 81°, at least two positioning rods 200 are provided, and are fixed on the same side of the support frame 110 in opposite positions, and the support frame 110 is also provided with a limit block 210 corresponding to the positioning rod 200. The limit block 210 can ensure that when the elevator door frame leans against the positioning rod 200, the lower end of the door frame abuts against the limit block 210, thereby avoiding the side of the door frame from shaking during welding and preventing its bottom from moving relative to each other. The inclination angle of the door frame in this embodiment is 81°, and the side of the door frame has a certain angle of inclination to increase the aesthetics of the door frame. It should be noted that the welding angle of the positioning rod 200 in this application can be determined according to actual production needs.

[0058] As a preferred embodiment, the mold of the present application is made by welding, and the preferred material for welding is galvanized square steel with a length, width and thickness of 25mm*25mm*3mm. The galvanized square steel has good corrosion resistance and rigidity, so it can ensure the service life of the door frame mold frame 100 and avoid its own deformation thereby affecting the welding accuracy of the door frame.

[0059] As another optional implementation, the positioning rod 200 can also be connected by bolts, which requires drilling holes on the support frame 110 and the positioning rod 200. The positioning rod 200 is combined with a movable positioning frame 400" to simplify the processing flow of the door frame, eliminate the situation where the door frame welding consumes a lot of manpower, make the finished door frame high in precision, and improve its adaptability during assembly.

[0060] Embodiment 2:

[0061] A method for constructing an elevator door frame comprises the following steps:

[0062] S1. Door cover folding: The door cover is made of galvanized steel plate folding, and the door cover has three sections, namely two side edges and a top edge;

[0063] S2, door cover positioning: install the door cover mold frame 100 on the ground, then put the two sides of the door cover that have been folded into the door cover mold frame 100 and abut against the positioning rod 200;

[0064] S3, door cover welding: fix the two sides of the door cover that have been positioned with its top edge, and fix the three sections by welding to complete the door cover production;

[0065] S4. Install the door frame fixing angle steel: install the fixing angle steel used to fix the door frame to the left and right walls of the elevator entrance through collision bolts;

[0066] S5, fixing the mounting mold frame 300: adjusting the position of the mounting mold frame 300 and mounting it on the elevator door;

[0067] S6. Door cover fixing and installation: After the installation formwork 300 is installed and fixed, the door cover is placed on the installation formwork 300, the position of the door cover is adjusted, and the door cover is welded to the door cover fixing angle steel to complete the installation;

[0068] S7. Filling: After the door frame is installed, cement grouting is performed on the gaps in the wall.

[0069] Furthermore, in step S1, the door frame is formed by folding the galvanized steel sheet using a CNC folding machine.

[0070] Furthermore, the galvanized steel plate has three sections, two sections with a length and width of 2300mm*430mm, and one section with a length and width of 1400mm*430mm.

[0071] Furthermore, in step S7, the gaps around the door frame are sealed with M42.5 cement mortar refractory material.

[0072] In this embodiment, the elevator door cover mold frame 100 is first manufactured, and then the elevator door cover is produced by the door cover mold frame 100. Then, the installation mold is manufactured, and during the installation process of the elevator door cover, the installation mold frame 300 is used for support, so that the elevator door cover can be quickly and accurately positioned and fixed. This construction method is suitable for elevator door covers made of stainless steel plates and galvanized steel plates.

[0073] Before the door frame formwork 100 and the installation formwork 300 are manufactured, the operator needs to do preparatory work, and needs to check the galvanized steel plates, galvanized angle steels and galvanized square tubes to be folded, and check their quality and quantity.

[0074] The door frame is made of galvanized steel plate folding. When marking and folding the door frame, the door frame folding adopts CNC folding machine, which can accurately control the folding angle to ensure the installation quality. The galvanized steel plate has three sections, two sections with a length and width of 2300mm*430mm, and one section with a length and width of 1400mm*430mm. Because the length of the steel plate will be shortened by 3mm when folding, this expansion and contraction should be considered when cutting to ensure the dimensional accuracy.

[0075] When manufacturing the door cover mold frame 100, the door cover mold frame 100 is made of 50mm*30mm*3mm galvanized square tubes, assembled into a rectangular frame (support frame 110) on an assembly table, and reinforced with 50mm*30mm*3mm galvanized square tubes (reinforcement ribs 120) at the four corners to prevent welding deformation.

[0076] When welding the positioning rod 200 for door cover angle positioning, the positioning rod 200 is made of 40mm*20mm*3mm galvanized square tube, welded to one end of the door cover mold frame 100 according to the actual width of the door cover, and the inclination angle is 81°. This degree should be strictly controlled to ensure that the door cover inclination angle meets the design requirements. Due to the different sizes of elevator door frames, the position of the door cover angle positioning rod 200 is determined according to the actual construction requirements.

[0077] When the movable door frame angle positioning frame 400 is manufactured, the positioning frame 400 is made of 25mm*25mm*3mm galvanized angle steel, and the inclination angle is the same as 81°. This degree should be strictly controlled to ensure that the door frame inclination angle meets the design requirements.

[0078] Similarly, for the door frame installation formwork 300, the installation formwork 300 is made of a 40mm*20mm*3mm galvanized square tube.

[0079] When the door cover is made as a whole, put the folded galvanized steel plate on the door cover mold frame 100, adjust the diagonal size, spot weld it firmly and then full weld it. When welding, ensure that the weld height is not less than 3mm.

[0080] Installation of door frame fixed angle steel: The fixed angle steel is made of 50mm*50mm*4mm galvanized angle steel, cut according to the design size, and firmly fixed to the wall with M10*100mm expansion bolts.

[0081] When installing the door frame installation formwork 300, install the door frame installation formwork 300 on the elevator door according to the construction requirements, adjust the position and lock it. Control the verticality and horizontality of the door frame installation and the flatness with the wall: the verticality deviation of the door frame shall not exceed 1.5mm, and the horizontality deviation shall not exceed 1.5mm, ensuring that it is flush with the wall and matches the elevator door frame.

[0082] After the door cover is installed, the gaps are sealed. Before sealing, the door cover installation quality should be checked to ensure that the door cover installation size and position are correct and the horizontal and vertical deviations are within the control range. After passing the inspection, the gaps around the door cover are sealed with refractory materials such as M42.5 cement mortar to ensure tight sealing.

[0083] In the present embodiment, the door frame is formed by a mold frame and prefabricated and installed as a whole, which saves time and effort, is economical and efficient, and changes the idea of ​​traditional assembly and installation of elevator door frame components. The door frame is made by using a door frame mold frame 100, and the formed door frame is assembled in coordination with the installation mold frame 300. The welded door frame can be quickly and accurately positioned and installed, which improves the installation accuracy of the elevator door frame, ensures the construction quality of the door frame, and avoids rework. The installation mold frame 300 can be reused many times, which greatly simplifies the installation steps and improves the construction efficiency of the elevator door frame.

[0084] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
