Description

Technical Field

[0001] This application relates to the technical field of protective devices, and particularly to a protective device for building demolition. Background Art

[0002] During the building demolition process, construction enclosures are set up along the outer wall of the perimeter columns for one week. The enclosures can reduce the impact of debris, dust, and noise generated during the demolition process on the surrounding environment and personnel. The enclosures isolate the construction area from the public area, improving the safety of construction equipment and materials. At the same time, the construction enclosures help maintain the order of the construction site, enabling the construction activities to proceed in an orderly manner, reducing the entry of unauthorized personnel into the construction area, and thus reducing the occurrence of accidents.

[0003] Currently, the enclosures are fixed to the ground by bolts. When the side walls of the enclosures are subjected to wind force or other acting forces, the enclosures are prone to shaking and instability, thereby affecting the connection stability of the enclosures and resulting in a relatively easy occurrence of enclosure tipping. Summary of the Invention

[0004] In order to improve the connection stability of the enclosures, this application provides a protective device for building demolition.

[0005] A protective device for building demolition provided by this application adopts the following technical solutions:

[0006] A protective device for building demolition includes a support frame. The support frame is arranged on the outer side of the perimeter column. A safety net is installed on the side of the support frame away from the perimeter column. A support assembly is arranged on the outer wall of the perimeter column. The support assembly includes a connecting hoop and a support rod. The connecting hoop is sleeved on the outer wall of the perimeter column. One end of the support rod is fixed to one end of the connecting hoop, and the other end of the support rod is fixed to one side of the support frame. An inclined support rod is fixed to the outer wall of the connecting hoop, and the top of the inclined support rod is fixed to the top of the support frame.

[0007] By adopting the above technical solution, the enclosure columns in the site are utilized to connect the enclosure columns with the support frame. The enclosure columns can provide supporting force or tensile force for the support frame. Under the action of the support assembly, when the side wall of the support frame is subjected to wind force or other acting forces, the support assembly transfers the acting forces received by the support frame to the enclosure columns. The foundation of the enclosure columns is relatively firm, so that it can bear the acting forces transferred by the support assembly, reduce the situation that the support frame shakes unstably, and further reduce the situation that the support frame topples. Under the action of the inclined support rod, the inclined support rod, the support assembly and the support frame form a triangle, and the triangle has stability, making the support of the inclined support rod on the top of the support frame more stable. When the support frame is subjected to acting forces in the horizontal direction, the acting forces received by the top of the support frame are transferred to the enclosure columns through the inclined support rod, and the enclosure columns provide supporting force for the inclined support rod, thereby making the position of the support frame more stable and reducing the situations of the support frame shaking unstably and toppling.

[0008] Preferably, there are two support assemblies, and the two support assemblies are distributed at the top and bottom of the enclosure column, and the inclined support rod is connected to the support assembly located at the top.

[0009] By adopting the above technical solution, the two support assemblies are distributed at the top and bottom of the enclosure column, so as to support the top and bottom of the support frame respectively. Moreover, the support assembly located at the top also has the function of supporting the inclined support rod. With the cooperation of the support assembly located at the top and the inclined support rod, the support of the top of the support frame is made more stable.

[0010] Preferably, a base is fixed to the bottom surface of the support frame.

[0011] By adopting the above technical solution, under the action of the base, the contact area between the bottom surface of the base and the ground is relatively large, thereby increasing the friction between the base and the ground. At the same time, the gravity of the bottom is increased, so as to further reduce the situation that the support frame shakes unstably.

[0012] Preferably, inclined struts are respectively fixed to the side walls of the two long sides of the support frame, and the inclined struts are obliquely arranged on the side walls of the support frame.

[0013] By adopting the above technical solution, under the action of the inclined struts, the inclined struts and the support frame form a triangular structure. The inclined struts connect each part of the support frame into a whole, increasing the structural stability of the support frame, improving the overall stiffness of the support frame, and reducing the deformation and vibration of the support frame when it is stressed.

[0014] Preferably, the connecting hoop includes connecting blocks. There are two connecting blocks, and the two connecting blocks are arranged oppositely. A storage cavity is formed between the two connecting blocks. The enclosure column is located in the storage cavity. The inner walls of the two connecting blocks are in contact with the outer wall of the enclosure column, and the two ends of the two connecting blocks are detachably and fixedly connected.

[0015] By adopting the above technical solution, the enclosure column is located in the storage cavity, and both ends of the two connecting blocks are detachably and fixedly connected, so that the size of the storage cavity can be controlled until the two connecting blocks are fixed on the outer wall of the enclosure column, thereby improving the applicability of the connecting hoop.

[0016] Preferably, the support frame is a double-row floor-standing scaffolding.

[0017] By adopting the above technical solution, the support frame is a double-row floor-standing scaffolding, so that a double support structure can be provided. Compared with a single-row scaffolding, the horizontal bars of the double-row floor-standing scaffolding provide a larger support area, which helps to disperse and balance the load, distribute the load more evenly over a larger area, make the support frame more stable, and reduce the situation of the support frame shaking unstably due to the force.

[0018] Preferably, the base is an isosceles trapezoidal seat, and the width of the bottom surface of the base is greater than the width of the top surface of the base.

[0019] By adopting the above technical solution, the base is an isosceles trapezoidal seat, and the width of the bottom surface of the base is greater than the width of the top surface of the base, so as to further increase the contact area between the bottom surface of the base and the ground, and move the center of gravity of the support frame and the base downward, thereby further reducing the situation of the support frame shaking unstably.

[0020] Preferably, a connecting plate is arranged at one end of the connecting block close to the support frame. One side of the connecting plate is fixed to the side wall of one of the connecting blocks, and one end of the support rod is fixed to the side of the connecting plate close to the support frame.

[0021] By adopting the above technical solution, under the action of the connecting plate, the contact area with the connecting block is increased, thereby improving the connection stability between the support rod and the connecting block.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Utilize the enclosure columns in the site to connect the enclosure columns with the support frame. The enclosure columns can provide support force or tensile force for the support frame. Under the action of the support component, when the side wall of the support frame is subjected to wind force or other acting forces, the support component transfers the acting force received by the support frame to the enclosure column. The foundation of the enclosure column is relatively firm, so it can bear the acting force transmitted by the support component, reduce the situation of the support frame shaking unstably, and further reduce the situation of the support frame toppling. Under the action of the inclined support rod, the inclined support rod, the support component and the support frame form a triangle, and the triangle has stability, making the support of the inclined support rod on the top of the support frame more stable. When the support frame is subjected to a horizontal acting force, the acting force received by the top of the support frame is transmitted to the enclosure column through the inclined support rod, and the enclosure column provides support force for the inclined support rod, thus making the position of the support frame more stable and reducing the situation of the support frame shaking unstably and toppling.

[0024] 2. Two support components are distributed at the top and bottom of the enclosure column to respectively support the top and bottom of the support frame. Moreover, the support component located at the top also has the function of supporting the inclined support rod. With the cooperation of the support component located at the top and the inclined support rod, the support of the top of the support frame is made more stable. Description of the Drawings

[0028] The following is a further detailed description of the present application in combination with the attached Figure 1-2 drawings.

[0029] The embodiment of the present application discloses a protective device for building demolition.

[0030] Refer to Figure 1, A protective device for building demolition, including a support frame 1. The support frame 1 is a double-row floor-standing scaffolding, which can provide a double support structure. Compared with a single-row scaffolding, the horizontal bars of the double-row floor-standing scaffolding provide a larger support area, which helps to disperse and balance the load, distribute the load more evenly over a larger area, make the support frame 1 more stable, and reduce the situation of the support frame 1 shaking unstably due to stress. The support frame 1 is arranged on the outer side of the perimeter column 3. Diagonal braces 11 are respectively fixed on the side walls of the two long sides of the support frame 1. The diagonal braces 11 are obliquely fixed on the side walls of the support frame 1 through fasteners. Under the action of the diagonal braces 11, the diagonal braces 11 and the support frame 1 form a triangular structure. The diagonal braces 11 connect each part of the support frame 1 into a whole, increase the structural stability of the support frame 1, improve the overall stiffness of the support frame 1, and reduce the deformation and vibration of the support frame 1 when stressed.

[0031] A safety net 2 is fixed on the outer side of the support frame 1. Under the action of the safety net 2, the construction area is isolated from the public area. The safety net 2 can block the debris and dust generated during construction, reduce the impact of debris and dust on the surrounding environment and personnel, and at the same time reduce the situation of non-construction personnel entering the construction area, thereby reducing the occurrence of accidents.

[0032] A base 12 is fixed on the bottom surface of the support frame 1. The base 12 is fixed to the ground by bolts. In the embodiment of the present application, the base 12 is an isosceles trapezoidal seat, and the width of the bottom surface of the base 12 is greater than the width of the top surface of the base 12, so that the contact area between the bottom surface of the base 12 and the ground is larger, thereby increasing the friction between the base 12 and the ground, and moving the center of gravity of the support frame 1 and the base 12 downward. At the same time, the gravity at the bottom is increased, thereby further reducing the situation of the support frame 1 shaking unstably.

[0033] Referring to Figure 1 and Figure 2 , A support assembly 4 is arranged on the outer wall of the perimeter column 3. The support assembly 4 includes a connecting hoop 41 and a support rod 42. The connecting hoop 41 includes a connecting block 411. There are two connecting blocks 411. The two connecting blocks 411 are arranged oppositely. A placement cavity is formed between the two connecting blocks 411. The perimeter column 3 is located in the placement cavity. The inner walls of the two connecting blocks 411 are in contact with the outer wall of the perimeter column 3. A connecting plate 43 is arranged at one end of the connecting block 411 close to the support frame 1. One side of the connecting plate 43 is in contact with the side wall of one connecting block 411. The two connecting blocks 411 and the connecting plate 43 are fixed by bolts. The other ends of the two connecting blocks 411 are also fixed by bolts. During the process of tightening the bolts to fix the two connecting blocks 411, the size of the placement cavity can be controlled until the two connecting blocks 411 are fixed on the outer wall of the perimeter column 3. One end of the support rod 42 is fixed to the side of the connecting plate 43 close to the support frame 1, and the other end of the support rod 42 away from the connecting plate 43 is fixed to the support frame 1 through a fastener.

[0034] The number of support components 4 on a perimeter column 3 depends on specific circumstances. In the embodiment of this application, there are two support components 4 on a perimeter column 3, and the two support components 4 are distributed at the bottom and top of the perimeter column 3. By using the perimeter column 3 in the site, the perimeter column 3 is connected to the support frame 1. The perimeter column 3 can provide support force or tensile force for the support frame 1. Under the action of the support component 4, when the side wall of the support frame 1 is subjected to wind force or other acting forces, the support component 4 transmits the acting force received by the support frame 1 to the perimeter column 3. The foundation of the perimeter column 3 is relatively firm, so it can bear the acting force transmitted by the support component 4, reduce the situation that the support frame 1 shakes unstably, and further reduce the situation that the support frame 1 topples over.

[0035] To further support the support frame 1, an installation plate 51 and an installation column 52 are provided at one end of the connection block 411 located at the top of the perimeter column 3 away from the connection plate 43. The structure of the installation plate 51 is the same as that of the connection plate 43, and the connection manner between the installation plate 51 and the connection block 411 is the same as that between the connection plate 43 and the connection block 411. In the embodiment of this application, it will not be elaborated in detail. One end of the installation column 52 is fixed on the side of the installation plate 51 away from the connection block 411. One end of the installation column 52 away from the installation plate 51 is fixed with an inclined support rod 53 through a fastener. The top end of the inclined support rod 53 is fixed on the top of the support frame 1 through a fastener. Under the action of the inclined support rod 53, the inclined support rod 53, the support component 4 and the support frame 1 form a triangle. The triangle has stability, making the support of the inclined support rod 53 on the top of the support frame 1 more stable. When the support frame 1 is subjected to a horizontal acting force, the acting force received by the top of the support frame 1 is transmitted to the perimeter column 3 through the inclined support rod 53, and the perimeter column 3 provides support force for the inclined support rod 53, thereby making the position of the support frame 1 more stable and reducing the situation that the support frame 1 shakes unstably and topples over.
