Description

Technical Field

[0001] The utility model relates to the technical field of building protection, in particular to a unit-shaped steel structure cantilevered protection shed and protection equipment. Background Art

[0002] During the construction of high-rise construction projects, in order to avoid damage to people and property within the falling radius due to falling objects from heights, cantilevered protective sheds are usually used as safety measures to solve this hidden danger. At present, cantilevered protective sheds on the market are constructed with steel pipe scaffolding, and scaffolding boards are laid on the surface of the shed.

[0003] The use of traditional cantilevered protective sheds itself has certain safety hazards: during the installation phase, construction workers need to perform a large amount of suspended work, which poses a major safety hazard; during use, due to the large weight of the shed, poor integrity of the scaffolding planks, and poor sealing of the dense mesh safety net used as the facade closure measure, the entire protective shed itself is accompanied by a certain risk of falling objects from heights. At the same time, since the traditional installation and erection method requires a large amount of space on the building floors, it also brings many inconveniences to subsequent construction operations; during the dismantling process, construction workers also need to perform a large amount of suspended work; in addition, many material turnover, shelving and other links will be generated during the construction process, which brings adverse factors to economic benefits.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0049] In the existing technology, the installation materials of traditional cantilevered protective sheds need to occupy a large amount of internal space of the building floors. The loading and unloading process causes construction workers to perform a large number of suspended operations, which affects construction operations and poses a safety hazard.

[0050] Based on the above problems in the prior art, the utility model provides a unit-shaped steel structure cantilevered protective shed, such as Figure 1 and Figure 2 As shown, the unit standardized steel structure cantilever protective shed includes: a support unit 100, the support unit 100 includes a number of main keels 110 arranged at intervals and in parallel, a number of secondary keels 120 perpendicular to and fixedly connected to the main keels 110, and a panel 130 fixedly laid on the secondary keels 120; the main keel 110 is provided with a lifting lug 111, and the lifting lug 111 is provided through the panel 130; a guardrail unit 200, adjacent parts of several guardrail units 200 are connected and vertically fixedly arranged on the panel 130; a movable flap 300, the movable flap 300 is used to connect adjacent support units 100; a pulling member 400, one end of the pulling member 400 is detachably connected to the lifting lug 111, and the other end is fixedly connected to the embedded part 500 provided on the superstructure.

[0051] The utility model provides modular support units 100 and guardrail units 200, so that the protective shed can be assembled in the factory according to actual needs. During installation, it is fixed by hoisting and pulling parts 400, and adjacent support units 100 are connected to each other through movable flaps 300 on the support units 100. This eliminates the need to occupy the internal space of the building floor for placing materials and reduces the number of construction workers operating in the air, effectively reducing safety hazards and greatly improving the installation efficiency and the overall strength of the protective shed.

[0052] In the above embodiment, if Figure 1 As shown, the main body of the unit-shaped steel structure cantilevered protective shed of the present invention is composed of a support unit 100, a guardrail unit 200, a movable flap 300 and a pulling member 400.

[0053] Specifically, the main function of the support unit 100 is to protect construction workers and equipment from the risk of falling from height. This type of protective facility is often used at construction sites to ensure the safety of workers during work. The design and construction of the cantilevered protective shed is intended to provide a temporary protective environment, especially in high-altitude operations and dangerous working environments, to reduce the occurrence of high-altitude falls and object impact accidents. In this embodiment, Figure 1 As shown, the support unit 100 is composed of a main keel 110, a secondary keel 120, and a panel 130. Several main keels 110 are spaced a predetermined distance apart and arranged in parallel. The main keel 110 serves as the actual fixing component of the support unit 100 and also serves as a foundation for the installation of other components. The secondary keel 120 is laid above the main keel 110. Several secondary keels 120 are laid perpendicular to the main keel 110 and are fixedly connected to the main keel 110 to form a plate-frame structure. Panels 130 are also arranged on the secondary keels 120. Panels 130 are specifically metal plates. Panels 130 are fixedly connected to the secondary keels 120 to form a platform structure that can receive falling objects from high altitudes to prevent them from striking people or objects below.

[0054] The guardrail unit 200 is used to prevent construction workers from falling. The guardrail unit 200 is set on the panel 130 of the support unit 100, corresponding to one side of the panel 130. During the specific setting, the guardrail unit 200 is a preset component and can be installed on the support unit 100 according to actual needs. Several guardrail units 200 can be set on one support unit 100, and a wrap-around installation can be formed on multiple sides of the support unit 100, thereby achieving a multi-directional enclosure effect.

[0055] The movable flap 300 is used to connect adjacent support units 100. Since the length of a single support unit 100 is limited, it is often necessary to continuously set up multiple support units 100 when installing a cantilevered protective shed on a construction layer of a building. In order to make the multiple support units 100 form a stable overall structure, in this embodiment, the adjacent support units 100 are connected by setting a movable flap 300, thereby improving the installation stability of the cantilevered protective shed and improving the resistance performance when receiving falling objects.

[0056] The pulling member 400 is used to fix the above-mentioned support unit 100. In this embodiment, a plurality of lugs 111 are provided on one side of the main keel 110 corresponding to the panel 130. The lugs 111 pass through the panel 130 so that the position of the lugs 111 with the ear holes is located above the panel 130. Figure 2As shown, when the support unit 100 is hoisted to the predetermined position, by connecting one end of the pulling member 400 to the lifting ear 111 and fixing the other end to the embedded member 500 on the superstructure, one end of the support unit 100 can be pulled, and the other end of the support unit 100 is placed on the bottom plate of the building on this layer through the main keel 110. By fixing and limiting, the installation of the support unit 100 and the guardrail unit 200 on the support unit 100 can be completed. Then, by installing movable flaps 300 on adjacent support units 100, several support units 100 can be connected to each other to form a stable whole.

[0057] In this embodiment, the above-mentioned support units 100 and guardrail units 200 can be pre-produced in the factory according to actual needs, and the movable flaps 300 and the pulling members 400 can be produced as prefabricated parts. When it is necessary to install a cantilevered protective shed on the building, several support units 100, guardrail units 200, movable flaps 300 and pulling members 400 can be transported to the site as needed, and the support units 100, guardrail units 200 and movable flaps 300 can be pre-assembled on site, and finally hoisted to the predetermined position by a crane, and the installation is completed by the pulling member 400.

[0058] This embodiment pre-assembles the modular support unit 100 and the guardrail unit 200. During the installation process, construction workers only need to work in the air when installing the pulling member 400 and the movable flap 300, which effectively reduces the safety risks of construction workers and greatly improves the installation efficiency of the cantilevered protective shed.

[0059] Based on the above embodiments, in one possible implementation of the present invention, as Figure 3 and Figure 7 As shown, the length of the above-mentioned main keels 110 should be greater than the width of the panel 130, so that one end of the main keel 110 can extend from the cantilevered protective shed area to the interior of the building on this floor, forming a corresponding placement with the interior floor of the building on this floor, so that construction workers can use tools to fix the main keel 110 and then fix the support unit 100. In a specific embodiment, as shown in FIG. Figure 2 As shown, a number of circulating pressure rings 112 are provided on the main keel 110 at the position corresponding to the outside of the panel 130. The circulating pressure rings 112 are the pressure rings commonly used in the construction industry in the prior art, which can be easily fixed to the ground or ballast structure through tools such as bolts and anchors, thereby achieving the effect of fixed connection with the ground of the building on this floor.

[0060] In this embodiment, if Figure 3 and Figure 7 As shown, the panel 130 is arranged at one end corresponding to a plurality of main keels 110, which can ensure the flat appearance of the cantilevered protective shed and facilitate transportation and placement during the loading and unloading process.

[0061] Furthermore, if Figure 1 As shown, a lifting ear 111 structure is also provided at a position on the main keel 110 corresponding to the outside of the panel 130, and multiple lifting ear 111 structures are provided at a position on the main keel 110 corresponding to the panel 130, wherein the lifting ear 111 located on the panel 130 close to the guardrail unit 200 is used to connect with the pulling member 400, and the lifting ears 111 located at other positions of the panel 130 and the lifting ears 111 on the main keel 110 corresponding to the outside of the panel 130 are used to undertake the lifting function during lifting. The specific setting position of the lifting ear 111 should balance the center of gravity of the support unit 100 and the guardrail unit 200, so it is not specifically limited in this application, and those skilled in the art can arrange it according to the actual situation of the support unit 100.

[0062] In another embodiment of the present invention, Figure 2 As shown, the above-mentioned pulling member 400 is specifically composed of a first steel wire 410, a second steel wire 420 and a basket bolt 430, wherein one end of the first steel wire 410 is fixedly connected to the lifting ear 111, and one end of the second steel wire 420 is fixedly connected to the embedded part 500. A basket bolt 430 is also provided between the first steel wire 410 and the second steel wire 420, and both ends of the basket bolt 430 are fixedly connected to the other ends of the first steel wire 410 and the second steel wire 420 respectively. In this embodiment, the relative distance between the first steel wire 410 and the second steel wire 420 can be adjusted by the basket bolt 430, so as to fine-tune the lifting level of the support unit 100, and the adjacent support units 100 can be located in the same horizontal plane, so as to facilitate the subsequent installation of the movable flap 300.

[0063] In this embodiment, the embedded part 500 is a detachable embedded bolt. In the prior art, buildings often adopt prefabricated buildings, that is, the floor slabs, frames, etc. of the building are pre-cast and then assembled. Embedded bolts are preset in each module of the prefabricated building to improve the accuracy of assembly during the installation process. The utility model sets the embedded part 500 corresponding to the position of the cantilevered protective shed as a detachable embedded bolt, which can be easily connected with the second steel wire 420, thereby facilitating the installation of the pulling member 400 and the support unit 100, which is beneficial to improving assembly efficiency.

[0064] In another embodiment of the present invention, Figure 3 and Figure 4As shown, in order to make the structure of the support unit 100 more stable and the adjacent support units 100 easier to correspond, in this embodiment, the support unit 100 also includes a plurality of angle steels 140, and the plurality of angle steels 140 are spaced a predetermined distance apart and arranged perpendicular to the secondary purlins 120, and the plurality of angle steels 140 are fixedly connected to the plurality of secondary purlins 120. In the specific arrangement, the angle steels 140 should be arranged on the side of the corresponding support unit 100 and at the position between the adjacent main purlins 110. The angle steels 140 are parallel to the main purlins 110, which can form a supplementary fixation for the support unit 100, and at the same time ensure that the docking sides of the support unit 100 and the adjacent support units 100 are flat, thereby facilitating rapid corresponding assembly.

[0065] In a specific embodiment, Figure 7 As shown, the above-mentioned panel 130 can be specifically set up using a patterned steel plate, which is provided with a hollow hole structure and a concave and convex pattern. On the one hand, it can reduce the overall weight of the cantilevered protective shed, and on the other hand, it can provide anti-slip performance, reducing the rolling distance when an object falls on the panel 130, thereby preventing the object from breaking through the guardrail unit 200 and sliding under the building.

[0066] In actual settings, such as Figure 3 and Figure 6 As shown, the main keel 110 is located on one side of the secondary keels 120 and is welded to the main keel 110. This welding step can be completed during pre-installation in the factory.

[0067] like Figure 3 and Figure 5 As shown, the above-mentioned panel 130 is located on the other side of several secondary keels 120, that is, the side away from the main keel 110. The panel 130 is welded to several secondary keels 120. This welding step can be completed during pre-installation in the factory. When the cantilever protective shed is actually hung, the main keel 110 corresponds to the bottom and the panel 130 corresponds to the top.

[0068] In another embodiment of the present invention, Figure 1As shown, the guardrail unit 200 is specifically composed of a frame 210, a protective plate 220 and a column 230, wherein the frame 210 is a rectangular frame 210, and a plurality of first ear plates 211 are respectively provided on opposite ends of the frame 210. The protective plate 220 is fixedly provided on one side of the frame 210, thereby forming a shielding and protective effect. The column 230 is a rectangular column structure, and the column 230 is provided on one side of the frame 210, corresponding to the position of the plurality of first ear plates 211 on one side of the frame 210. 0 is respectively provided with a plurality of second ear plates 231, and the second ear plates 231 are adapted to the first ear plates 211 in shape and correspond in position. During the specific installation, the first ear plate 211 and the second ear plate 231 can be connected by a bolt structure, so that the column 230 is fixedly connected to the frame 210. When connecting multiple guardrail units 200, the second ear plate 231 on the other side of the column 230 is connected to the first ear plate 211 on the adjacent frame 210, thereby realizing continuous assembly of guardrail units 200.

[0069] In this embodiment, the guardrail unit 200 can be prefabricated into a fixed size. During pre-assembly, the number of guardrail units 200 to be installed is determined according to the length of the panel 130 on the support unit 100, and the guardrail units 200 are welded and fixed. Therefore, after hoisting, only the corresponding guardrail units 200 on the adjacent support units 100 need to be assembled, reducing the workload of construction personnel in overhead operations.

[0070] In another embodiment of the present invention, Figure 8 As shown, the above-mentioned movable flap 300 specifically includes a connecting plate 310, a hinge 320 and a reinforcing rib 330, wherein the connecting plate 310 is a rectangular plate for fixedly connecting to the panel 130 in the support unit 100, and a plurality of hinges 320 are provided, and the plurality of hinges 320 are evenly arranged on one side of the connecting plate 310, and the hinge 320 has two rotatably connected hinges, one of which is welded to the connecting plate 310, and the other hinge is used to be fixedly connected to the panel 130 of the adjacent support unit 100. In this embodiment, a reinforcing rib 330 is also provided for the portion of the hinge 320 that is welded to the connecting plate 310, and the reinforcing rib 330 is fixedly provided at the position on the connecting plate 310 corresponding to the hinge 320, thereby forming the effect of the reinforcing rib 330 and the connecting plate 310 clamping the above-mentioned hinge 320, which can prevent the edge of the connecting plate 310 from deforming or the hinge 320 from falling off the connecting plate 310.

[0071] During actual installation, Figure 9As shown, after two or more support units 100 are hoisted and installed on this floor of the building, the construction workers weld the upper end of the hinge 320 away from the connecting plate 310 to the panel 130 of the adjacent support unit 100. Since the hinge 320 is small in size, the welding amount is small, which can reduce the amount of overhead operation required by the construction workers. At the same time, since the two sides of the hinge 320 can be rotated, the rotating part can make up for the installation tolerance of the adjacent support units 100, thereby providing an operating margin while fixing the connection, which is convenient for the construction workers to install and operate.

[0072] Based on the above implementation, the actual installation process of the unitized steel structure cantilevered protective shed of the utility model is as follows:

[0073] First, the support unit 100, the guardrail unit 200, the movable flap 300 and the pulling member 400 are prefabricated in the factory and transported to the site for pre-assembly after prefabrication, or pre-assembled directly in the factory;

[0074] The pre-assembly process is to weld a corresponding number of guardrail units 200 on the panel 130 of a support unit 100 so that the side of the support unit 100 is protected by the guardrail unit 200, and then weld one side of the movable flap 300 to one side of the panel 130 of the support unit 100 to complete the pre-assembly. Figure 1 As shown;

[0075] During actual installation, Figure 2 As shown, the pre-assembled whole is hoisted to a predetermined height by an on-site crane and the lifting lugs 111 on the main keel 110, corresponding to the installation position of the cantilevered protective shed of the current building. After alignment, it is fixed to the ground of the current building through the turnover pressure ring 112, and then the pulling piece 400 is used to connect the lifting lugs 111 on the main keel 110 close to the protective unit and the embedded parts 500 on the superstructure to form traction. The distance between the first steel wire 410 and the second steel wire 420 is adjusted by the basket bolt 430 so that the main keel 110 is placed in a state parallel to the ground of the current building, thus completing the installation of the single-unit standardized steel structure cantilevered protective shed.

[0076] like Figure 9 As shown, after the installation of two adjacent units of standardized steel structure cantilevered protective sheds is completed, the freely movable side of the movable flap 300 is welded to the panel 130 on the adjacent support unit 100 to form a connection, and the opposite guardrail units 200 are connected to form a continuous structure. Multiple adjacent standardized steel structure cantilevered protective sheds are installed in sequence, and the following is formed. Figure 9 Final installation style shown.

[0077] In this embodiment, by modularizing the support unit 100 and the guardrail unit 200, it is convenient for production, transportation and pre-assembly. In conjunction with the movable flap 300 and the pulling member 400, the workload of construction workers in the air can be reduced when hanging and installing the standardized steel structure cantilevered protective shed, and the installation of adjacent standardized steel structure cantilevered protective sheds can be completed simply, thereby effectively improving construction efficiency and reducing the safety risks of construction workers in the air.

[0078] Based on the above embodiments, the utility model also provides a protective device, which includes the unit-shaped steel structure cantilevered protective shed in the above embodiments, and the unit-shaped steel structure cantilevered protective shed includes: a support unit, the support unit includes a number of main keels arranged at intervals and in parallel, a number of secondary keels perpendicular to and fixedly connected to the main keels, and a panel fixedly laid on the secondary keels; the main keels are provided with lifting ears, and the lifting ears are provided through the panel; a guardrail unit, adjacent parts of several guardrail units are connected and vertically fixed on the panel; a movable flap, the movable flap is used to connect adjacent support units; a pulling member, one end of the pulling member is detachably connected to the lifting ear, and the other end is fixedly connected to the embedded part provided on the superstructure. The utility model provides modular support units and guardrail units, so that the protective shed can be assembled in the factory according to actual needs. During installation, it is fixed by hoisting and pulling parts, and adjacent support units are connected to each other by movable flaps on the support units. There is no need to occupy the internal space of the building floor for placing materials, and the construction workers can be reduced to operate in the air, which effectively reduces safety hazards and can greatly improve the installation efficiency and the overall strength of the protective shed.
