Description

Technical Field

[0001] The present invention relates to the technical field of invisible railings, and in particular to an invisible railing structure, a railing crossbeam processing method and an invisible railing processing method. Background Art

[0002] Figure 1 This is an exploded view of the crossbeam of an existing invisible railing. The crossbeam includes a crossbeam connector 12 and a crossbeam frame 21 fixed to the wall. The crossbeam connector 22 is fixedly connected to the crossbeam frame 21 by multiple screws 25. This crossbeam is prone to production problems. For example, the holes for the screws 25 are punched separately in the crossbeam frame 21 and the crossbeam connector 22 at the factory. However, these two holes are easily misaligned, which poses a safety risk to the punch press operator and reduces the production and installation efficiency of the product. When using such a crossbeam to produce invisible railings, screws that pass through the crossbeam are also used to connect the vertical beams, which also leads to misalignment between the crossbeams and the vertical beams and reduces installation efficiency. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] A hidden railing structure, which includes a plurality of cross beams and two vertical side beams connected between the cross beams, at least one of the cross beams is a reference cross beam, and the reference cross beam includes a cross beam frame and a cross beam connector integrally formed on one side of the cross beam frame, the two ends of the cross beam connector are cut off so that both ends of the reference cross beam form end cuts, one end of each vertical side beam is correspondingly installed in an end cut and fixed to the reference cross beam, the inner side surface of the vertical side beam is in contact with the end face of the cross beam connector, and the end face of the vertical side beam is in contact with the side face of the cross beam frame.

[0009] Preferably, there are two reference beams, which are symmetrically arranged one above and one below, and the two ends of the vertical side beam are respectively installed in the end cuts of the two reference beams.

[0010] Preferably, the ends of the vertical side beams are threadedly connected to the reference cross beams.

[0011] Preferably, the end of the vertical rod is threadedly connected to the reference beam.

[0012] A method for processing a railing beam, wherein the railing beam is the above-mentioned reference beam, comprises the following steps:

[0013] 1. Clamping: Fix several reference beams on the operating table;

[0014] 2. Processing the end cuts: Processing the end cuts includes two processes: longitudinal sawing of the reference beam and transverse sawing of the reference beam.

[0015] The method for transverse sawing the reference beam is to use a sawing machine, which is provided with a transverse saw blade parallel to the operating table. The transverse saw blade rotates and moves relative to the operating table so that the transverse saw blade advances toward the reference beam and cuts a transverse incision at the connection between the beam connecting member and the beam frame of all the reference beams.

The longitudinal saw blade rotates and moves relative to the operating table so that the longitudinal saw blade feeds toward the reference beam, and a longitudinal incision is sawed on the beam connecting parts of all reference beams. The longitudinal incision intersects with the transverse incision to cut off the excess material and form the end incision.

[0017] Preferably, at least one U-shaped cut is provided in the middle of the beam connector.

[0020] A method for processing an invisible railing, wherein the invisible railing includes the above-mentioned invisible railing structure, comprises the following steps:

[0021] a. Processing the reference beam, using the above-mentioned railing beam processing method to process the reference beam, processing the U-shaped cut and end cuts on the reference beam;

[0022] b. Install the vertical side beams, fitting the ends of each vertical side beam into an end cutout corresponding to the vertical side beam so that the inner side of the vertical side beam fits in with the end face of the crossbeam connector and the end face of the vertical side beam fits in with the side face of the crossbeam frame, and the ends of the vertical side beams are connected and fixed to the corresponding reference crossbeam;

[0023] c. Install the vertical rods and fit the ends of each vertical side beam into a corresponding U-shaped cutout, so that the left and right side surfaces of the vertical rods respectively fit with the end surfaces of the cross beam connectors on both sides, and the end surfaces of the vertical rods fit with the side surfaces of the cross beam frames, and connect and fix the ends of the vertical rods to the corresponding reference cross beams.

At the same time, during the installation process, there is no need to connect the cross beam connector and the cross beam frame with screws, nor is there any need to consider the positioning problem of connecting the two together. The entire production and installation process is very convenient and quick; combining the profiles into one can also save a lot of material costs;

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0036] Reference Figures 2 to 7 The present invention proposes an invisible railing structure, which includes a plurality of cross beams and two vertical side beams 1 connected between the cross beams. Among the cross beams, at least one is a reference cross beam 2. The reference cross beam 2 includes a cross beam frame 21 and a cross beam connector 22 integrally formed on one side of the cross beam frame 21. The two ends of the cross beam connector 22 are cut off so that both ends of the reference cross beam 2 form an end cutout 201. One end of each vertical side beam 1 is correspondingly installed in an end cutout 201 and is connected and fixed to the reference cross beam 2, such as by welding, riveting or screw connection. The inner side surface of the vertical side beam 1 (that is, the side surface of the two vertical side beams 1 facing each other) is in contact with the end surface of the cross beam connector 22, and the end surface of the vertical side beam 1 is in contact with the side surface of the cross beam frame 21.

[0037] Since the crossbeam connector 22 and the crossbeam frame 21 are an integrally formed structure, when the end of the crossbeam connector 22 is cut to form the above-mentioned end cutout 201, it is possible to ensure that the relative position accuracy of the end cutout 201 and the crossbeam frame 21 is high. The two side surfaces of the end cutout 201 are the end surface of the crossbeam connector 22 and one side surface of the crossbeam frame 21, respectively. When installing the vertical side beam 1, the vertical side beam 1 is positioned by the two side surfaces of the end cutout 201, and the positioning accuracy is high. At the same time, during the installation process, there is no need to connect the crossbeam connector 22 and the crossbeam frame 21 together with screws, nor is there any need to consider the positioning problem of connecting the two together. The entire production and installation process is very convenient and quick.

[0038] Furthermore, at least a section is cut out of the middle of the beam connector 22 to form at least one U-shaped incision 202 on the reference beam 2. The invisible railing structure also includes at least one vertical rod 3 connected between the beams. One end of each vertical rod 3 is correspondingly installed in a U-shaped incision 202 and is connected and fixed to the reference beam 2, such as by welding, riveting or screw connection. The left and right side surfaces of the vertical rod 3 are respectively fitted with the end surfaces of the beam connectors 22 on both sides, and the end surfaces of the vertical rod 3 are fitted with the side surfaces of the beam frame 21.

[0039] The function of the vertical rod 3 is to improve the strength of the invisible railing when the reference beam 2 is long. The U-shaped cutout 202 is used to install the end of the vertical rod 3, which is conducive to accurate positioning of the vertical rod 3.

[0040] As a preferred solution of the present invention, there are two reference beams 2 , which are symmetrically arranged one above and one below. The two ends of the vertical side beam 1 are respectively installed in the end cutouts 201 of the two reference beams 2 .

[0041] The present invention also proposes a processing method for producing the above-mentioned reference beam 2, which comprises the following steps:

[0042] 1. Clamping: Fix several reference beams 2 on the operating table (not shown);

[0043] 2. Processing the end cut 201. Processing the end cut 201 includes two steps: longitudinal sawing of the reference beam 2 and transverse sawing of the reference beam 2.

[0044] The method for transverse sawing the reference beam 2 is to use a sawing machine, which is provided with a transverse saw blade 41 parallel to the operating table. The transverse saw blade 41 rotates and moves relative to the operating table so that the transverse saw blade 41 advances toward the reference beam 2 and cuts a transverse incision at the connection between the beam connecting member 22 and the beam frame 21 of all the reference beams 2.

[0045] The method for longitudinally sawing the reference beam 2 is to use a saw machine, which is provided with a longitudinal saw blade 42 perpendicular to the reference beam 2. The longitudinal saw blade 42 rotates and moves relative to the operating table so that the longitudinal saw blade 42 feeds toward the reference beam 2, and a longitudinal incision is sawed in the beam connecting parts 22 of all reference beams 2. The longitudinal incision intersects with the transverse incision to cut off the excess material and form an end incision 201.

[0046] There is no order in which the two processes of longitudinal sawing of the reference beam 2 and transverse sawing of the reference beam 2 are performed, and either process can be performed first.

[0047] Preferably, the number of the reference beams 2 is two or more, and the reference beams 2 are installed in parallel and side by side on the operating table.

[0048] For reference beams 2 having at least one U-shaped cutout 202 formed in the middle of the beam connector 22, a step of machining the U-shaped cutout 202 is required after step 1 above. The U-shaped cutout 202 is machined using a sawing machine equipped with a thickened saw blade 43 perpendicular to the reference beam 2. The thickened saw blade 43 rotates while moving relative to the operating table, advancing toward the beam connector 22 and sawing a U-shaped cutout 202 on all reference beams 2. There is no order in which to perform the U-shaped cutout 202 or the end cutout 201; either process may be prioritized.

[0049] The thickened saw blade 43 is generally formed by stacking a plurality of thinner saw blades, and the number of stacked saw blades is determined according to the width of the U-shaped incision 202. Of course, if production cost is not considered, a saw blade of suitable thickness can also be customized.

[0050] Furthermore, the crossbeam frame 21 has a reference surface 211, which is generally the upper surface of the crossbeam frame 21. The crossbeam connector 22 is integrally formed on the reference surface 211. The bottom surface of the U-shaped cutout 202 is parallel to or coplanar with the reference surface 211. The bottom surface of the U-shaped cutout 202 can be higher or lower than the reference surface 211, with the distance between the two being 0-0.2 mm, which is achieved by controlling the vertical position of the thickened saw blade 43. This design ensures that after the reference crossbeam 2 is assembled, the cumulative assembly error is within 0.5 mm.

[0051] Similarly, as a preferred embodiment of the present invention, the bottom surface of the end cutout 201 is also parallel to or coplanar with the reference plane 211. The bottom surface of the end cutout 201 can be higher or lower than the reference plane 211, and the distance between the two is 0-0.2 mm.

[0052] In the prior art, if one wants to process a notch similar to the end cut or U-shaped notch 202 described above, a CNC machining center is generally used for processing, and the milling cutter therein is mainly used to process the notch. The specific operation steps are: ① Write a processing program; ② Select the tool used in the program; ③ Place the profile in the fixture and start processing; ④ After processing, remove the profile and clean the aluminum chips and oil stains. This processing method has the following disadvantages: ① It requires personnel with high comprehensive qualities to write the processing program, which invisibly raises the threshold for use; ② The processing efficiency is low. For example, taking the processing of two 2.6-meter profiles as an example, this method takes 5 minutes; ③ A large amount of aluminum chips are generated during the processing, which is difficult to clean; ④ After processing, cutting oil adheres to the profile, which is difficult to clean.

[0053] The advantages of the processing method of the present invention for two-in-one aluminum profiles are mainly as follows: 1. Simple operation, only manual data input is required, such as the length of the two end cuts 201 and the spacing between the middle cuts; 2. High efficiency, it only takes about 40 seconds to process two 2.6-meter profiles; 3. Excellent processing quality, no aluminum chips or oil stains are generated during the processing.

[0054] The present invention also proposes a method for processing an invisible railing, wherein the invisible railing includes the above-mentioned invisible railing structure, and the method comprises the following steps:

[0055] a processing reference beam 2, using the above-mentioned railing beam processing method to process the reference beam 2, processing the U-shaped cutout 202 and the end cutout 201 on the reference beam 2;

[0056] b. Install the vertical side beams 1, and fit the ends of each vertical side beam 1 into an end cutout 201, so that the inner side of the vertical side beam 1 fits with the end face of the crossbeam connector 22, and the end face of the vertical side beam 1 fits with the side face of the crossbeam frame 21, and the end of the vertical side beam 1 is connected and fixed with the corresponding reference crossbeam 2;

[0057] c. Install the vertical rod 3 and fit the end of each vertical side beam 1 into a corresponding U-shaped cutout 202, so that the left and right side surfaces of the vertical rod 3 respectively fit with the end surfaces of the cross beam connectors 22 on both sides, and the end surfaces of the vertical rod 3 fit with the side surfaces of the cross beam frame 21, and connect and fix the ends of the vertical rod 3 to the corresponding reference cross beam 2.

[0058] Preferably, the ends of the vertical side beams 1 and the ends of the vertical rods 3 are connected and fixed to the reference cross beam 2 by screws.

[0059] The invisible railing processing method of the present invention adopts the above-mentioned railing beam processing method to process the reference beam 2, and has the advantages of the above-mentioned railing beam processing method. In addition, when assembling the vertical side beam 1 and the vertical bar 3, the two are positioned by the end cutout 201 and the U-shaped cutout 202, and the positioning accuracy is high. The formed invisible railing structure is stable and the force is evenly distributed.

[0060] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
