Description

Technical Field

[0001] This utility model application belongs to the field of hard protection technology for scaffolding, specifically relating to a retractable hard protection device for scaffolding and scaffolding. Background Technology

[0002] During the construction process, in order to ensure the smooth progress of the construction, it is inevitable to erect scaffolding as a working platform. In addition to installing external scaffolding safety nets, hard protective devices must also be erected on the first floor and every three floors of the scaffolding to ensure the safety of construction workers.

[0003] However, the following problems exist during the installation and use of physical protection:

[0004] In the construction of physical protective structures, bamboo plywood is typically laid out and square timber is installed underneath as a keel. However, this method requires carpenters to lay out each bamboo plywood sheet and fix it with nails one by one. This operation is difficult and tedious to install and remove, which is extremely time-consuming and labor-intensive for construction workers, greatly extending the construction period.

[0005] Therefore, there is an urgent need to design a new type of hard protective device. This device can ensure the safety of construction personnel and solve the problems of cumbersome, time-consuming and labor-intensive installation of the original hard protective equipment. It can simplify the construction process, facilitate installation and disassembly, reduce the workload of construction personnel, and ultimately improve construction efficiency and increase economic benefits.

[0006] This utility model application discloses a retractable rigid protective device for scaffolding and scaffolding, in order to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the first aspect of this utility model provides a retractable rigid protective device for scaffolding, comprising: a support base, which is a rectangular frame structure and has a connecting part at the bottom for connecting the scaffolding; a telescopic plate assembly, which is slidably installed at one end of the support base; and a top plate assembly, the lower end of which is fixedly installed on the support base and is disposed above the telescopic plate assembly; the telescopic plate assembly and the top plate assembly together constitute a rigid protective layer.

[0008] Furthermore, the support base is formed by two square tubes and two channel steels, with the two channel steels fixedly connected by two parallel square tubes; each square tube has a connecting part on its lower end face.

[0009] Furthermore, vertical elongated holes for installing the top plate assembly are made on the two channel steels.

[0010] Furthermore, the top plate assembly includes a top plate, and connecting ears are fixedly installed at both ends of the lower end face of the top plate, with mounting holes on the connecting ears that match the vertical elongated holes.

[0012] Furthermore, there are two telescopic plate assemblies, which are symmetrically slidably fitted onto the support base.

[0013] Furthermore, the telescopic plate assembly includes: a telescopic plate, which is a rectangular plate structure; sliding channel steels, which are fixedly installed at the left and right ends of the lower end face of the telescopic plate, and the openings of the two sliding channel steels are opposite to each other, and the sliding channel steels are matched with the channel steels of the support base; the sliding channel steels are correspondingly sleeved on the channel steels.

[0014] Furthermore, each sliding channel steel has a connecting hole at its outer end.

[0015] Furthermore, the connecting part is a flexible pipe clamp.

[0016] The second aspect of this utility model provides a scaffold, which is equipped with the aforementioned retractable rigid protective device; a plurality of retractable rigid protective devices are arranged closely together on the crossbars of the scaffold.

[0017] The advantages and positive effects of this utility model are:

[0018] 1. The retractable rigid protective device for scaffolding disclosed in this utility model application uses steel for all components, which has better rigidity. At the same time, the support base can also replace the function of the keel. The design of the base as a rectangular frame structure saves materials and reduces costs.

[0036] The specific embodiments of this utility model application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0037] In the technical solutions disclosed in this utility model application, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" are generally defined based on the drawing direction of the corresponding figures, while "inner" and "outer" refer to the inner and outer sides relative to the outline of the component or structure itself. Furthermore, in the description of the accompanying drawings, the same reference numerals in different figures denote the same elements.

[0038] According to the first aspect of this utility model application, a retractable rigid protective device for scaffolding is disclosed, such as... Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, it includes:

[0039] Support base 3, combined Figure 3 As shown, the support base 3 is a rectangular frame structure with a connecting part 4 at the bottom for connecting to the scaffolding. Specifically, the connecting part 4 is fastened to the crossbar of the scaffolding;

[0040] Telescopic plate assembly 1, combined with Figure 1 As shown, the telescopic plate assembly 1 is slidably mounted on one end of the support base 3;

[0041] Top panel assembly 2, combined with Figure 1 As shown, its lower end is fixed on the support base 3, and the top plate assembly 2 is located on the upper part of the telescopic plate assembly 1.

[0042] The telescopic plate assembly 1 and the top plate assembly 2 together constitute a rigid protective layer.

[0043] In the above technical solution, the retractable hard protective device is placed on the crossbar of the scaffold and connected to the crossbar of the scaffold through the connecting part 4 at the bottom of the support base 3. Then, according to the spacing of the crossbars in the scaffold, the telescopic plate assembly 1 is slidably installed at one end of the support base 3 to adjust it: the telescopic assembly 1 is slidably extended outward along the support base 3 to the required length, so that the telescopic plate assembly 1 and the top plate assembly 2 together form a hard protective layer, and are connected and densely arranged with other retractable hard protective devices in front and behind to form a hard protective layer.

[0044] In this technical solution, all components are made of steel. The top plate assembly 2 and the telescopic plate assembly 1 are both made of steel, giving this retractable rigid protective device excellent rigidity. Meanwhile, the supporting base 3 also acts as a keel; its rectangular frame design further saves materials and reduces costs. Furthermore, the length of this retractable rigid protective device can be adjusted via the telescopic plate assembly 1, which not only facilitates installation but also expands the protective area of ​​the rigid protective layer, further reducing laying work and shortening the construction period.

[0045] In summary, this device overcomes the cumbersome, time-consuming, and labor-intensive technical problems of existing hard protection systems, which require carpenters to lay and nail all the hard protection panels (such as bamboo plywood) one by one during installation. It reduces the amount of hard protection panel laying work, thus simplifying the construction process, reducing workload, and improving construction efficiency and economic benefits. Furthermore, this retractable hard protection device can also be used as scaffolding.

[0046] In this embodiment, such as Figure 3 As shown, the support base 3 is formed by two square tubes 302 and two channel steels 301, with the two channel steels 301 fixedly connected by two parallel square tubes 302; each square tube 302 has a connecting part 4 on its lower end face. In some embodiments, such as Figure 3 As shown, the two channel steels 301 are also provided with vertical elongated holes 301a for installing the top plate assembly 2. The vertical elongated holes 301a on the channel steels 301 can realize the connection between the support base 3 and the top plate assembly 2. Moreover, the installation height of the top plate assembly 2 can be adjusted arbitrarily as needed using the vertical elongated holes 301a, so that the top plate assembly 2 can clamp the telescopic plate assembly 1 installed below it.

[0047] In some specific implementation methods, such as Figure 4 As shown, the top plate assembly 2 includes a top plate 201, and connecting ears 202 are fixedly mounted at both ends of the lower end face of the top plate 201. The connecting ears 202 have mounting holes 202a that match the vertical elongated hole 301a; preferably, as shown... Figure 4 As shown, a reinforcing steel strip 203 is also fixedly installed on the lower end face of the top plate 201. The two ends of the reinforcing steel strip 203 are respectively fixedly connected to the connecting lug 202. The reinforcing steel strip 203 fixedly installed on the lower end face of the top plate 201 can further replace the keel, which is equivalent to installing the keel at the same time as installing the top plate 201. This eliminates the process of carpenters installing square timber keels one by one in the existing technology, greatly reducing the workload of workers and improving construction efficiency. In terms of specific material selection, angle steel can be used to facilitate the operation of construction workers.

[0048] In other implementations, such as Figure 1 , Figure 5 As shown, there are two telescopic plate assemblies 1, which are symmetrically slidably sleeved on the support base 3.

[0049] Specifically, the telescopic plate assembly 1 includes:

[0050] The telescopic plate 101 is a rectangular plate structure;

[0051] Sliding channel steels 102 are fixedly installed on the left and right ends of the lower end face of the telescopic plate 101, and the openings of the two sliding channel steels 102 are opposite to each other. The sliding channel steels 102 are matched with the channel steels 301 of the support base 3. The sliding channel steels 102 are correspondingly sleeved on the channel steels 301.

[0052] In the above technical solution, the sliding channel steels 102 at the left and right ends of the lower end face of the telescopic plate 101 are respectively sleeved on the channel steels 301 at both ends of the corresponding support base 3, and the channel steels 301 serve as guide rails. The support base 3 and the telescopic plate assembly 1 are tightly slidably connected to each other, ensuring that the telescopic plate assembly 1 can slide stably and accurately at the end of the support base 3 without deviating.

[0053] In other implementations, such as Figure 5 As shown, each sliding channel steel 102 has a connecting hole 102a at its outer end. This design can tightly connect all the retractable hard protective devices that are laid side by side on the scaffold, increasing the connection strength between the retractable hard protective devices and improving the overall structural strength of the scaffold.

[0054] In some other implementations, such as Figure 3 , Figure 6As shown, the connecting part 4 is made of elastic pipe clamp. The elastic pipe clamp has a simple structure and is easy to use, making it convenient for construction workers to install or remove this telescopic rigid protective device on the scaffold.

[0055] In addition, galvanized steel is usually used in the selection of specific steel materials. Galvanized steel has strong corrosion resistance and high rigidity, which can extend the service life of this device.

[0056] Based on the above technical solutions, this disclosure also provides a scaffolding, such as... Figure 7 As shown, the scaffolding is equipped with the aforementioned retractable rigid protective device. Since the scaffolding provided in this disclosure possesses all the characteristics of the aforementioned retractable rigid protective device, it will not be described again here to avoid repetition.

[0057] This utility model application exemplarily describes the steps for using this hardware protection device, as follows:

[0058] S1. First, lay several hard protective devices on the scaffold, with the hard protective devices in the same row arranged closely together. Then, use the elastic pipe clamps on the lower end of the support base 3, i.e. the connecting part 4, to securely connect with the crossbar of the scaffold.

[0059] S2. Adjust a row of hard protective devices on one side of the scaffold according to the spacing of the horizontal bars in the scaffold: slide the telescopic component 1 outward along the channel steel 301 on the support base 3 so that the telescopic components 1 of the adjacent hard protective devices can abut against each other and form a closed effect between the telescopic plates 101 of the adjacent telescopic components 1.

[0060] S3. Using the vertical elongated hole 301a of the support base 3, combined with the height of the telescopic plate 101, adjust and fix the installation height of the top plate 201 so that after installation, the top plate 201 is located on the upper part of the telescopic plate 101 and the lower end face of the top plate 201 abuts against the upper end face of the telescopic plate 101.

[0061] S4. Adjust the telescopic components 1 of the other columns of hard protection devices according to the telescopic degree of the hard protection device telescopic components 1 described above.

[0062] S5. After all the telescopic components 1 are adjusted, the adjacent hard protective devices in the same row are connected together by bolts through the connecting holes 102a. The top plate 201 and telescopic plate 101 on each hard protective device, the telescopic plates 101 on adjacent hard protective devices, and the top plates 201 are all closely arranged to form an integral hard protective layer.

However, this application is not limited to the specific details of the above embodiments.
