Description

Technical Field

[0001] The utility model belongs to the technical field of building profile structures, and particularly relates to a connecting structure of a stacked ladder board. Background Art

[0002] Nowadays, there are various styles of building profiles. Besides meeting the requirements of building appearance beauty, many functional structures have emerged one after another, such as heat preservation, moisture proof, heat insulation, ventilation, etc. Among them, the building exterior wall structure in the form of a stacked ladder board has the characteristics of low price and convenient assembly. Many office buildings have installed stacked ladder boards on their exterior walls, which can not only beautify the exterior wall but also play a certain functional protection role. However, the current installation form of the stacked ladder board is still to first fix and lock the fastening columns on the wall surface, then drill holes on the fastening columns, and lock the stacked ladder board on the fastening columns through screws to fasten the stacked ladder board. However, this installation method requires frequent drilling and tightening of screws, which increases the workload of the installation workers. Moreover, in the case of long-term rain and water immersion, the screws will quickly rust and become prone to breakage, resulting in the risk of the stacked ladder board falling, and also making the subsequent replacement of the stacked ladder board more troublesome. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a connecting structure of a stacked ladder board. After pre-opening fastening holes on the fastening columns, a mating port, a clamping post and a clamping plate are respectively arranged on the ladder board member. A number of ladder board members are stacked and inserted from bottom to top in sequence. When replacement is needed, only a screwdriver needs to be inserted into the adjustment hole to lift the clamping plate, and then quick disassembly can be carried out. Since the ladder board member needs to have a certain deformation ability, it is particularly suitable for stacked ladder boards made of aluminum products.

[0004] To achieve the above object, the technical solution adopted by the utility model is:

[0005] A connecting structure of a stacked ladder board, comprising a wall base, a fastening column, a ladder board member and a heat preservation cotton. The fastening column has a hollow structure inside. The inner end face of the fastening column is detachably connected to the wall base. A number of longitudinally spaced fastening holes are arranged on the outer end face of the fastening column. The lower end of the ladder board member is detachably connected to the fastening holes. The ladder board member includes several groups. A number of the ladder board members are stacked and abutted on the outer end face of the fastening column from bottom to top in sequence; the lower edge of the upper ladder board member abuts the upper edge of the lower ladder board member on the fastening column.

[0006] A clamping interface is provided on the lower end surface of the fastening hole. A mating port is provided on the upper edge of the ladder plate member. A clamping post is provided on the lower edge of the ladder plate member. A clamping plate is provided at the end of the clamping post. The mating port of the ladder plate member corresponds to the clamping interface of the upper fastening hole. The clamping post of the ladder plate member is fitted and connected within the clamping interface of the lower fastening hole. The inner side surface of the clamping plate abuts against the inner side surface of the clamping interface of the lower fastening hole. The clamping post is a deformable elastic member. An adjustment hole penetrating the clamping post is provided on the outer side wall of the ladder plate member.

[0007] Two sets of the fastening posts form a set. The two sets of fastening posts are parallel to each other and do not contact each other. Two sets of clamping interfaces are provided on the lower end surface of the fastening hole. The mating port, clamping post and clamping plate of the ladder plate member all include two sets and are symmetrically arranged left and right on the ladder plate member. The left and right ends of the ladder plate member are respectively inserted on the two sets of fastening posts. The heat insulation cotton is arranged between the two sets of fastening posts.

[0008] For the connection structure of the stacked ladder plate adopting this structure, the fastening post is detachably connected to the wall base through its inner end surface, aiming to provide sufficient supporting force for the ladder plate member inserted into the fastening hole on the outer end surface of the fastening post. Two sets of fastening posts form a set. The left and right ends of the ladder plate member are respectively inserted on the two sets of fastening posts and are stacked in sequence from bottom to top. In order to enable the lower ladder plate member to be pressed by the upper ladder plate member to achieve sequential lamination, a clamping interface is opened on the lower end surface of the fastening hole. The clamping interface corresponds to the mating port on the upper edge of the ladder plate member. A clamping post is provided on the lower edge of the ladder plate member, and a clamping plate is provided at the end of the clamping post. Therefore, during the assembly process of the ladder plate member, first insert the clamping post on the lower edge of the ladder plate member into the clamping interface on the fastening hole and press it to the bottom, so that the inner side surface of the clamping plate abuts against the inner side surface of the clamping interface, and push up the upper end of the ladder plate member with the clamping post as the rotation center and abut it against the outer end surface of the fastening post until the mating port on the upper edge of the ladder plate member corresponds to the clamping interface on the upper fastening hole. When inserting another ladder plate member at the upper end of this ladder plate member, the lower end of the upper ladder plate member will press the upper edge of the lower ladder plate member during the insertion process of the clamping post and the clamping interface, so that the lower ladder plate member is kept fastened. Therefore, by assembling from bottom to top in sequence, each layer of ladder plate member can be pressed and fixed, eliminating the need for drilling and screwing for fixation, saving a lot of time for workers in assembly. Moreover, even if a certain ladder plate member falls off, it will not affect the upper and lower ladder plate members.

[0009] It is convenient for workers during assembly, but it is also necessary to facilitate disassembly and replacement of a certain ladder plate. Therefore, the clamping post is set as an elastic part, and an adjustment hole penetrating the clamping post is provided on the outer side wall of the ladder plate. Therefore, when it is necessary to replace a single ladder plate, a screwdriver is inserted into the adjustment hole and pried upward, so that the clamping plate on the clamping post disengages upward from the area of the clamping opening, so that the lower end of the ladder plate can be disassembled, and then the ladder plate can be pulled downward to remove it. To install a ladder plate in the middle, first insert the upper edge of the ladder plate, then insert a screwdriver into the adjustment hole to lift the clamping plate first, and then press the screwdriver downward after inserting it into the fastening hole until the clamping post is inserted into the clamping opening for fixation. Since this structure requires not only the clamping post to be an elastic part that can deform, but also the ladder plate to have a certain deformation ability, the ladder plate made of aluminum products is particularly suitable for this structure.

[0010] Furthermore, a lock hole is provided on the inner end surface of the fastening post, and the lock hole corresponds to the fastening hole.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: By providing a mating port at the upper end of the ladder plate and a clamping post and a clamping plate at the lower end, which are respectively inserted into the clamping openings on two groups of fastening posts. After the lower ladder plate is inserted and combined, its upper end is fixed by being inserted and fastened by the upper ladder plate. Therefore, assembly can be carried out from bottom to top, which can make each layer of ladder plates be pressed and fixed, without the need to drill holes and lock screws for fixation, saving a lot of time for workers' assembly. Moreover, even if a certain ladder plate falls off, it will not affect the upper and lower ladder plates. To facilitate the disassembly and assembly of a certain ladder plate, the clamping post is set as an elastic part. When disassembly and assembly are required, a screwdriver is inserted into the adjustment hole and lifted upward to quickly disassemble the lower end of the ladder plate and take out the entire ladder plate for replacement. Since this structure requires not only the clamping post to be an elastic part that can deform, but also the ladder plate to have a certain deformation ability, the ladder plate made of aluminum products is particularly suitable for this structure.

[0024] Furthermore, a locking hole 23 is provided on the inner end surface of the fastening post 2, and the locking hole 23 corresponds to the fastening hole 21.

[0025] Description of the working mode of the present utility model:

[0026] For the connection structure of the stacked ladder plate with this structure, the fastening post 2 is detachably connected to the wall base 1 through its inner end surface, aiming to provide sufficient supporting force for the ladder plate member 3 inserted into the fastening hole 21 on the outer end surface of the fastening post 2. For the convenience of installing the fastening post 2, a locking hole 23 is provided on the inner end surface of the fastening post 2, and the locking hole 23 corresponds to the fastening hole 21. Therefore, when it is necessary to lock the fastening post 2 on the wall base 1, it can be directly locked through the fastening hole 21. The fastening posts 2 are provided in sets of two. The left and right ends of the ladder plate member 3 are respectively inserted into the two sets of fastening posts 2 and are stacked in sequence from bottom to top. In order to ensure that the lower ladder plate member 3 is pressed by the upper ladder plate member 3 to achieve sequential lamination, clamping interfaces 22 are opened on the lower end surface of the fastening holes 21, and the clamping interfaces 22 correspond to the mating ports 31 on the upper edge of the ladder plate member 3. The lower edge of the ladder plate member 3 is provided with clamping posts 32, and the end surface of the clamping posts 32 is provided with clamping plates 33. Therefore, during the assembly process of the ladder plate member 3, first insert the clamping posts 32 on the lower edge of the ladder plate member 3 into the clamping interfaces 22 on the fastening holes 21 and press them to the bottom, so that the inner side surface of the clamping plate 33 abuts against the inner side surface of the clamping interface 22. Push the upper end of the ladder plate member 3 upward with the clamping post 32 as the rotation center and abut it against the outer end surface of the fastening post 2 until the mating port 31 on the upper edge of the ladder plate member 3 corresponds to the clamping interface 22 on the upper fastening hole 21. When inserting another ladder plate member 3 at the upper end of this ladder plate member 3, the lower end of the upper ladder plate member 3 will press the upper edge of the lower ladder plate member 3 during the insertion process of the clamping post 32 and the clamping interface 22, so that the lower ladder plate member 3 is kept fastened. Therefore, by assembling from bottom to top in sequence, each layer of the ladder plate member 3 can be pressed and fixed, without the need to drill holes and lock screws for fixation, saving a large amount of time for workers in assembly. Moreover, even if a certain ladder plate member 3 falls off, it will not affect the upper and lower ladder plate members 3.

[0027] It is convenient for workers during assembly. However, when disassembling and replacing a certain ladder plate member 3, it also needs to be easy to disassemble and assemble. Therefore, the clamping post 32 is set as an elastic member, and an adjustment hole 34 penetrating the clamping post 32 is provided on the outer side wall of the ladder plate member 3. Therefore, when it is necessary to replace a single ladder plate member 3, a screwdriver is inserted into the adjustment hole 34 and pried upward, so that the clamping plate 33 on the clamping post 32 is disengaged from the area of the clamping interface 22 upward, so that the lower end of the ladder plate member 3 can be disassembled, and then the ladder plate member 3 is pulled downward to remove it. When installing the ladder plate member 3 in the middle, first insert the upper edge of the ladder plate member 3, and then insert a screwdriver into the adjustment hole 34 to lift the clamping plate 33 first. After inserting the fastening hole 21, press the screwdriver downward until the clamping post 32 is inserted into the clamping interface 22 for fixation. Since this structure requires not only the clamping post 32 to be an elastic member that can deform, but also the ladder plate member 3 to have a certain deformation ability, the ladder plate member 3 made of aluminum products is particularly suitable for this structure.

[0028] The beneficial effects of the present invention are as follows: By providing a mating port 31 at the upper end of the ladder plate member 3 and a clamping post 32 and a clamping plate 33 at the lower end, which are respectively inserted into the clamping interfaces 22 on the two groups of fastening posts 2. After the lower ladder plate member 3 is inserted and combined, its upper end is fixed by being inserted and fixed by the upper ladder plate member 3. Therefore, assembly can be carried out from bottom to top, and each layer of the ladder plate member 3 can be pressed and fixed, without the need to drill holes and lock screws for fixation, saving a lot of time for workers' assembly. Moreover, even if a certain ladder plate member 3 falls off, it will not affect the upper and lower ladder plate members 3. In order to facilitate the disassembly and assembly of a certain ladder plate member 3, the clamping post 32 is set as an elastic member. When disassembly and assembly are required, a screwdriver is inserted into the adjustment hole 34 and lifted upward to quickly disassemble the lower end of the ladder plate member 3 and take out the entire ladder plate member 3 for replacement. Since this structure requires not only the clamping post 32 to be an elastic member that can deform, but also the ladder plate member 3 to have a certain deformation ability, the ladder plate member 3 made of aluminum products is particularly suitable for this structure.
