Description

Technical Field

[0001] The present invention relates to the technical field of assembled staircases, and in particular to a clamped assembled staircase panel installation system and an installation method thereof. Background Art

[0002] Stair treads are divided into steel treads, wooden treads, stone treads, etc. according to their materials, and wooden treads are mainly used for stair treads used indoors in houses.

[0003] In the prior art, Patent No. CN201822138528.1 discloses a utility model named a tread template and a tread device, which includes a transverse tread arranged horizontally and a vertical tread arranged vertically; a top limit plate extends upward on the top surface of the front end of the transverse tread, and a bottom limit plate extends downward on the bottom surface of the rear end of the transverse tread; a bottom mounting surface is formed between the bottom limit plate and the rear end of the transverse tread; the top end of the vertical tread is mounted on the bottom mounting surface, and the inner surface of the vertical tread is also in contact with the bottom limit plate.

[0004] As described in the patent, the treads are installed on the prefabricated stair slabs by bolting, which will damage the wooden treads and leave obvious marks on the treads, significantly destroying the aesthetics of the tread installation. In addition, when the treads are installed on the stairs, leveling and squaring operations are required on site, which increases the on-site installation procedures and difficulty, and also leads to lower construction efficiency.

[0005] In addition, the connection between the vertical plate and the horizontal plate is not firm. During on-site installation, attention must always be paid to the installation accuracy between the vertical plate and the horizontal plate to avoid gaps between the vertical plate and the horizontal plate, between the vertical plate and the prefabricated stair plate, and between the horizontal plate and the stair plate. This increases the installation requirements and is not conducive to the construction workers installing the stair treads. Summary of the invention

[0006] The present invention provides a card-mounted assembled stair panel installation system and installation method. The device first installs a base plate on a prefabricated stair panel and performs a leveling operation on the base plate. During the installation of the base plate, the panel size can be measured and obtained, and then the size data of the treads and risers with relatively accurate dimensions can be obtained. The subsequent installation of the treads and risers is relatively simple. Moreover, the treads and risers are fixedly installed on the base plate in a card-mounted manner, which is friendly to wooden panels, and the installation efficiency and quality of the stair tread panels are also greatly improved, so as to solve the above-mentioned technical problems.

[0007] The technical solution of the present invention to solve the above-mentioned problem is: to provide a card-mounted assembled stair panel installation system, including a plurality of stair units connected end to end in sequence, the stair unit including a base plate laid on the stair prefabricated panel, a tread board card-mounted on the base plate, and a vertical plate card-mounted on the base plate; the tread board and the vertical plate are integrally provided with a plurality of card-mounting bodies on a single side surface; and also include a card-mounting groove body fixedly mounted on the base plate for card-mounting and accommodating the card-mounting body; the tread board and the vertical plate are also card-mounted and connected to completely cover the outer surface of the base plate.

[0008] Furthermore, the tread includes a horizontal main board and a connecting side board integrally provided with the horizontal main board for connecting the vertical board, and an embedded groove is provided at the outer edge of the connecting side board, and an embedded part embedded in the embedded groove is provided at the upper edge of the vertical board. The tread and the vertical board are connected by an embedded snap connection, so that the vertical board and the tread are connected in a hidden manner, and the embedded snap connection structure between the tread and the vertical board can also be used to further improve the installation stability of the panel installed on the stair steps, thereby improving the installation quality and aesthetics of the stair panel.

[0009] Furthermore, the vertical board includes a vertical board body with a plurality of clamping bodies integrally arranged on one side, an embedded component integrally arranged at the upper end edge of the vertical board body and embedded in the embedded groove, and a vertical board opening provided at the upper edge of the vertical board body. The vertical board covers the vertical step surface of the staircase with its vertical board body, and the upper end of the vertical board is connected to the tread plate by the embedded component. In addition, the technician can also remove the tread plate first and then remove the vertical board through the vertical board opening provided at the upper edge of the vertical board body, so that the installation and disassembly of the stair panel becomes relatively simple, which is conducive to the later maintenance and renovation of the stairs.

[0010] Furthermore, the fixing connection mode between the clamping slot body and the base plate is set to be nailing. The clamping slot body is nailed and fixed to the base plate, and the tread plate and the vertical plate are both clamped and connected to the clamping slot body, so that the tread plate and the vertical plate can be stably installed on the base plate without leaving nailing marks on the vertical plate or the tread plate, which well protects the tread plate and the vertical plate.

[0011] Furthermore, a tensioning cavity is provided in the middle of the clamping body, and the two sides of the clamping body are inclined in a direction away from the tensioning cavity, so that the clamping body can be clamped in the clamping slot body in a tensioning clamping manner. The clamping body and the clamping slot body are clamped in a tensioning clamping manner, which can provide convenience for disassembly of the clamping body and the clamping slot body based on the material characteristics of the stair structure and the panel, and facilitate the clamping installation of the stair panel and the base plate.

[0012] Furthermore, the inner wall of the clamping groove of the clamping groove body is provided with clamping serrations, and correspondingly, the corresponding side wall of the clamping body is also provided with clamping serrations. The clamping serration structure can further enhance the clamping and fixing effect between the clamping body and the clamping groove body.

[0013] Furthermore, the screws used when the clamping slot body is nailed to the base plate are cross countersunk screws, and a nailing groove is provided at the bottom of the clamping slot body. When the cross countersunk screw is nailed to the base plate, the tail end of the screw is also hidden in the nailing groove on the clamping groove to prevent the screw from protruding in the clamping groove of the clamping slot body and hindering the insertion of the clamping body into the clamping slot body.

[0014] Furthermore, the embedded groove is set in the form of a notch so that the embedded part will not be clamped in the embedded groove, avoiding interference between the adjustment operation of the tread and the adjustment operation of the opposing plate, thereby increasing the difficulty of panel installation and improving the installation quality of the stair panel.

[0015] The present invention also provides an installation method of a card-mounted assembled stair panel installation system, and the specific installation steps are as follows:

[0016] S1: Lay the base plate on the prefabricated stair slab so that the base plate covers the entire prefabricated stair slab;

[0017] S2: Level the base plate, measure the size of the stair surface after installing the base plate, and calculate the corresponding sizes of the treads and risers installed on the base plate;

[0018] S3: Pre-install the risers and treads from low to high according to the height of the stairs, find the nailing position of the card slot body, and nail the card slot body to the base plate;

[0019] S4: Install the risers and treads again from low to high to complete the installation of a single stair unit;

[0020] S5: Install the stair units from low to high in sequence to complete the assembly installation of the entire stair panel.

[0021] Furthermore, when installing the stair panels, the risers in the adjacent higher stair units are vertically abutted against the treads of the lower stair units, and the vertical and horizontal gaps between the risers and the treads are controlled to control the installation quality of the stair panels.

[0022] Beneficial effects of the present invention: The present invention provides a card-mounted assembled stair panel installation system, which includes a plurality of stair units with the same structure, and the installation of the stair units is divided into two parts: base plate installation and panel installation. Leveling during the installation of the base plate can provide great convenience for the installation of the stair panel; and the installed base plate itself is not used as an exposed panel surface, so the requirements for the base plate itself and the installation requirements for the base plate are not too high. Even if the base plate is installed incorrectly, it is convenient to adjust, and the fault tolerance rate is also increased. In this way, although the present invention sets two major steps of base plate installation and stair panel installation, it actually greatly reduces the difficulty of stair panel installation, and provides great convenience for the installation of assembled stair panels.

[0023] In addition, in the stair panel installation system of the present invention, since the panel (tread and riser) is connected to the base plate by a clamping method, it avoids nailing or other gluing methods to fix the panel directly to the base plate, so that the panel can be directly fixed to the base plate without damage, thus obtaining extremely excellent stair panel installation quality and extending the practical life of the stair panel. Moreover, the panel and the base plate can be disassembled and separated again, which also provides convenience for the later maintenance and repair of the stairs.

[0024] Compared with the traditional staircase structure and its installation method, the prefabricated installation method of the present invention greatly improves the installation efficiency and quality of the stair panels. Compared with the traditional staircase structure and the matching installation method, the prefabricated staircase panel structure of the present invention and its installation method, when used, can make the size of the stair panels (treads and risers) match the installation requirements very accurately before installation, and there is a pre-installation method to further reduce installation errors. Even if there is a small dimensional error in the actual installation, the on-site installer can eliminate the error by adjusting the snap-on size or adjusting the seamless position relationship between the riser and the tread. The prefabricated staircase panel structure and its installation method of the present invention are undoubtedly an excellent structure and solution with great prefabricated installation characteristics, which provides great convenience for the prefabricated installation of stair panels and is very creative.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device comprising the elements.

[0035] As a specific embodiment of the present invention, a card-mounted prefabricated stair panel installation system is provided. In order to achieve the purpose of prefabricated installation of the stair panels, the stair panel installation system in this embodiment includes a plurality of stair units connected in sequence. A stair unit is wrapped and installed on the outer peripheral surface of a stair step prefabricated panel, and adjacent stair units are contact-connected between adjacent stair step prefabricated panels.

[0036] See also Figure 1 In this embodiment, the stair unit includes a base plate 1, a tread 2, and a riser 3, wherein the base plate 1 is directly laid on the prefabricated stair step plate, and the tread 2 and the riser 3 are respectively snap-fitted and installed on the two exposed surfaces of the base plate 1, thereby forming a stair unit which is one of the unit components in the assembled stair panel installation system.

[0037] Combination Figure 1 and Figure 2 , in order to achieve the effect of quick installation. In this embodiment, the base plate 1 is set as a single straight plate. After cement is laid on the stairs, the base plates 1 are laid one by one on the stair surface while the cement is not dry, and the base plates 1 are leveled at the same time. In this process, the base plate 1 can be made of a composite plate with relatively low cost, relatively low construction requirements, and easy to adjust the cutting size, so that when installing the base plate 1, even if the installation posture of the base plate 1 needs to be adjusted or the size of the base plate 1 needs to be improved, it is convenient to install the base plate 1 and provide convenient conditions for the subsequent installation of the treads 2 and the risers 3. In addition, since the base plate 1 is an inner layer plate, the technicians will not have too high technical requirements when installing the base plate 1, and even the installation position accuracy requirements of the base plate 1 will be reduced. Similarly, when the clamping slot 5 is nailed and fixed on the base plate 1 later, there is no need to worry too much even if the screw structure damages the base plate 1.

[0038] In summary, when installing the base plate 1, only two factors, namely, installation flatness and size adjustment of the base plate 1, are considered, so its installation requirements are greatly reduced, providing a convenient basis for the installation of stair panels.

[0039] Since both the treads 2 and the risers 3 are stair surface plates, their materials and manufacturing processes are extremely high for aesthetic purposes. If the size and structure of the risers 3 or treads 2 need to be adjusted on site, not only will the adjustment operation be troublesome, but once a mistake is made, the risers 3 or treads 2 will be scrapped. Therefore, when installing the base plate 1, we measured the size of the base plate 1. Then, when installing the treads 2 and risers 3 later, the technicians can reversely calculate the size and quantity of the treads 2 and risers 3 to be installed based on the size of the base plate 1 they originally measured. The dimensional accuracy error of the prefabricated treads 2 and risers 3 based on this operation can be controlled within a very small range, thereby avoiding the operation of adjusting the size of the treads 2 or risers 3 again during the on-site installation process.

[0040] See also Figure 1 It can also be seen that based on the structural characteristics of the stair unit in the present application, during the installation of the treads 2 and the risers 3, the dimensional error of the treads 2 and the installation dimensional error of the risers 3 can be further accommodated by adjusting the installation positions of the treads 2 and the risers 3 respectively, so as to obtain higher installation quality.

[0041] The specific adjustment operations of adjusting the tread 2 or the vertical plate 3 include: adjusting the clamping size between the vertical plate 3 and the clamping groove body 5 to horizontally adjust the installation position of the vertical plate 3 and the tread 2; adjusting the thickness size of the embedded component 32 or the groove width of the embedded groove 23 to horizontally adjust the installation position of the vertical plate 3 and the tread 2; adjusting the height size of the embedded component 32 or the groove depth of the embedded groove 23 and adjusting the size or position of the vertical plate starting point 33 in coordination, thereby adjusting the vertical height installation position of the vertical plate 3 and the tread 2; and so on.

[0042] The above adjustment measures can further improve the size tolerance of the treads 2 and the risers 3 during the installation of the stair panels, further avoid cutting directly on the treads 2 or the risers 3, protect the integrity of the treads 2 and the risers 3, and improve the installation quality of the stair panels.

[0043] See also Figure 1 In this embodiment, the clamping and mounting structures between the tread plate 2 and the base plate 1, and between the vertical plate 3 and the base plate 1 are both clamping bodies 4 and clamping slots 5; the tread plate 2 is a horizontal mounting plate, and the vertical plate 3 is a vertical mounting plate; the tread plate 2 and the vertical plate 3 are both integrally provided with a plurality of clamping bodies 4, while the clamping slots 5 are separately provided, and the number of the clamping slots 5 is the same as the number of the clamping bodies 4, and one clamping slot 5 is connected to one clamping body 4. Based on this, the tread plate 2 can be inserted into the clamping slots 5 with the help of the clamping bodies 4, and the vertical plate 3 can also be inserted into the clamping slots 5 with the help of the clamping bodies 4, so that the tread plate 2 and the vertical plate 3 can be quickly clamped onto the base plate 1.

[0044] Based on this, in actual installation, the clamping structures of the tread 2 and the upright 3 are hidden inside the staircase; the tread 2 and the upright 3 are both hard panels, and the clamping body 4 is integrally arranged on the tread 2 or the upright 3; the clamping groove 5 must also be set as a hard structure to ensure that the tread 2 or the upright 3 will not deviate or loosen on the base plate 1; and the clamping body 4 must be able to be taken out of the clamping groove 5 again in an undamaged manner. Figure 5 In order to enable the tread plate 2 or the vertical plate 3 to be quickly mounted on the base plate 1 and to be easily disassembled, the clamping mode of the clamping member and the clamping slot 5 is changed to a tension clamping mode in the present application, rather than a traditional structural clamping mode. Moreover, the clamping member and the clamping slot 5 are still unconventional tension clamping modes. The clamping member body is only tilted 2° to the left and right sides, and a tensioning cavity 41 is provided in the middle of the clamping body 4, so that when the clamping body 4 is inserted into the clamping slot 5, the clamping body 4 can be slightly deformed inwards to be inserted into the clamping slot. The clamping body 4 can also be tensioned and clamped in the clamping slot 5 by relying on the high hardness of its own wood structure. The clamping body 4 and the clamping slot 5 are not easy to separate, so as to maintain a stable clamping capability. When necessary, the tread plate 2 can be lifted up and the vertical plate 3 can be lifted down by the vertical plate 3 opening provided on the vertical plate 3, so as to separate the clamping body 4 from the clamping slot 5 from each other. Most importantly, these operations of installing and removing the tread plate 2 or the upright plate 3 do not damage the original clamping performance of the clamping body 4 and the clamping slot 5, and can well maintain their clamping performance and ensure their usability.

[0045] In addition, combined Figure 5 and Figure 1 We can see that the clamping slot 5 in this embodiment is nailed to the base plate 1 by cross countersunk screws, and the cross countersunk screws nailed to the base plate 1 will not affect the structure of the tread 2 or the upright 3. A nailing groove is provided at the bottom of the clamping slot 5, and the cross countersunk screws are nailed through the clamping slot 5 and enter the base plate 1 to fix the clamping slot 5 at the marked position on the base plate 1.

[0046] In addition, the fixed connection mode between the clamping slot body 5 and the base plate 1 is set to be nailed. In order to further enhance the clamping stability of the clamping body 4 and the clamping slot body 5, in this embodiment, clamping serrations 6 are provided on the two vertical side walls of the clamping slot body 5, and clamping serrations 6 are also provided on the clamping side walls of the clamping body 4, so that when the clamping body 4 is clamped into the clamping slot body 5 under tension, the clamping serrations 6 form a serration limiting structure with each other, so as to further limit the clamping body 4 from being clamped in the clamping slot body 5, further limit the clamping body 4 from falling off from the clamping slot body 5, and further ensure the installation connection stability between the step board 2 or the vertical board 3 and the base plate 1.

[0047] See also Figure 3In this embodiment, the tread 2 is in an "L" shape as a whole. The tread 2 includes two plate bodies, namely, an integrally formed horizontal main plate 21 and a connecting side plate 22. The clamping body 4 is integrally arranged on a single side of the horizontal main plate 21. When the tread 2 is installed on the horizontal base plate 1, the horizontal main plate 21 and the base plate 1 are mainly clamped and installed. However, when the horizontal main plate 21 is installed on the base plate 1, the connecting side plate 22 will vertically contact the upper edge of the vertical plate 3, and the embedded groove 23 on the connecting side plate 22 can also clamp the embedded part 32 integrally arranged at the upper edge of the vertical plate 3, thereby connecting the tread 2 and the vertical plate 3 to each other in the stair unit, and having a connection integrity, so that the tread 2 and the vertical plate 3 can bear gravity to each other, thereby improving the practical bearing capacity of the stair panel.

[0048] Moreover, in this embodiment, the embedded groove 23 at the lower edge of the connecting side plate 22 is set as a groove structure in the form of a notch. When the step board 2 is installed on the base plate 1, the embedded groove 23 will cooperate with the vertical surface of the base plate 1 to form a real groove structure to restrict the embedded component 32 in the embedded groove 23. It should be noted that the embedded component 32 will not be clamped by the embedded groove 23 and cannot move horizontally at all. In fact, only after the installation is completed will the embedded component 32 be restricted in the embedded groove 23 to form a relatively stable connection structure, so that the step board 2 based on Figure 3 The horizontal right end surface of the staircase is flush with the horizontal right end surface of the vertical plate 3 to maintain the uniform flatness of the stair panel installation. In addition, the setting of the embedded component 32 can further participate in the installation and leveling of the tread 2. By adjusting the vertical height of the embedded component 32, the height of the left and right ends of the tread 2 can be adjusted. The embedded component 32 is also a built-in structure, and the change of its appearance will not affect the appearance of the stair panel, and will not reduce the appearance and structural consistency of the stair panel.

[0049] See also Figure 4 ,based on Figure 3 The vertical board 3 also includes a vertical board body 31 on which a plurality of clamping bodies 4 are integrally arranged on one side thereof, and an embedded component 32 integrally arranged at the upper end edge of the vertical board body 31. Combined with the special structure of the embedded groove 23, the embedded component 32 is also asymmetrically arranged at a single side position of the vertical board body 31, and the left end surface of the embedded component 32 coincides with the left end surface of the vertical board body 31, thereby facilitating the opening 33 of the vertical board at the upper right end edge of the vertical board body 31. The technician can lift up from the opening 33 of the vertical board to remove the tread 2, thereby avoiding removing the tread 2 at other positions of the stair panel to damage the tread 2.

[0050] The specific embodiment of the present invention also includes an installation method of a card-mounted assembled stair panel installation system, and the specific installation steps are as follows:

[0051] S1: Laying the base plate 1 on the prefabricated stair slab so that the base plate 1 covers the prefabricated stair slab;

[0052] S2: Leveling the base plate 1, and measuring the size of the stair surface after installing the base plate 1, and using this to calculate the corresponding sizes of the treads 2 and risers 3 installed on the base plate 1;

[0053] S3: pre-install the riser 3 and the tread 2 in order from low to high according to the height of the stairs, find the nailing position of the clamping slot 5, and nail the clamping slot 5 to the base plate 1;

[0054] S4: Install the riser 3 and the tread 2 again from low to high, completing the installation of a single staircase unit;

[0055] S5: Install the stair units from low to high in sequence to complete the assembly installation of the entire stair panel.

[0056] Based on the above installation method, when installing the stair panel, that is, installing the base plate 1, the tread 2, and the vertical plate 3, the base plate 1 and the stair panel are first divided into two parts, and the base plate 1 is installed when the stair is built, and the tread 2 and the vertical plate 3 are installed after the stair is formed. The adjacent stair units are only connected as a whole by cement structure, and the panel and the base plate 1 are actually only connected by contact without mechanical connection structure, which provides convenience for controlling the end surface flatness between the tread 2 and the vertical plate 3, so as to control the installation quality of the stair panel.

[0057] Anything not mentioned above is applicable to the prior art.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
