The terms are used solely to distinguish one component from another. For example, a first component could be referred to as a second component, and similarly, a second component could be referred to as a first component without departing from the teachings of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of a stated feature, number, step, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0031] This application discloses a construction safety protection device for protecting people who are active under a building during the construction period, so as to prevent people from being injured by mud and sand falling during the construction period or large pieces of buildings. Figures 1-10 As shown, the construction safety protection device of the present application includes a fixed base 10 fixed to the wall surface, a safety net 20, and a baffle 30, wherein the baffle 30 and the safety net 20 are both mounted on the fixed base 10, and the safety net 20 is located directly above the baffle 30. The safety net 20 is used to cushion the force caused by the fall of medium and large pieces of construction waste, and serves as the first safety protection component of the entire protection device. The baffle 30 is located on the smaller construction waste that falls and is filtered out from the safety net 20, protecting personnel from dust and other construction waste falling on them when passing under the construction area. At the same time, when a larger construction scaffold falls, if the first safety protection component cannot block it, a second safety protection is provided, thereby ensuring the safety of personnel in all aspects.

[0032] Specifically, the fixed base 10 is fixed to the outer wall of the building by expansion screws. The fixed base 10 includes a fixing assembly and a buffer assembly, wherein the fixing assembly includes a vertical fixed beam 111 and a horizontal fixed beam 112. The vertical fixed beam 111 is a metal rod, and bolt holes 1110 are respectively opened near the upper and lower ends of the vertical fixed beam 111. The expansion screws pass through the bolt holes 1110 to fix the vertical fixed beam 111 to the outer wall of the building. There are at least two vertical fixed beams 111, and the two are symmetrically arranged. Of course, in its specific implementation process, the number of vertical fixed beams 111 can be set according to the required length of safety protection, which can be three, four or more. In this application, the number is not specifically limited.

[0033] The number of buffer assemblies is consistent with the number of vertical fixed beams 111. The buffer assembly 12 is located on the vertical fixed beam 111 and includes a buffer spring 121, a connecting block 122, and a cover plate 123. The cover plate 123 is a metal plate that protects the buffer spring 121 inside. The edge of the cover plate 123 is bolted to the vertical fixed beam 111. The lower end of the buffer spring 121 is fixed to the bottom of the cover plate 123, and the upper end of the buffer spring 121 is connected to the connecting block 122. Two protruding slide rails 1231 are provided inside the cover plate 123. The left and right side walls of the connecting block 122 are respectively provided with recessed socket portions 1225. The socket portions 1225 are sleeved on the slide rails 1231. Therefore, when the connecting block 122 is subjected to external force, it will slide up and down along the slide rails 1231. The cover plate 123 is provided with a strip-shaped through hole 1232 , and another portion of the connecting block 122 is exposed outside the cover plate 123 through the through hole 1232 .

[0034] The connecting block 122 is provided with a member for fixing the transverse fixing beam 112. Specifically, the transverse fixing beam 112 is a straight metal rod. The bottom of the transverse fixing beam 112 extends downward to form a partially protruding plug-in portion 1121. The upper end surface of the connecting block 122 is partially recessed downward to form a plug-in slot 1221. When connected, the plug-in portion 1121 is inserted into the plug-in slot 1221 and then fixed by bolts. The side of the connecting block 122 away from the building wall is connected to the crossbeam 113 by bolts. The crossbeam 113 is a metal beam. At the end of the crossbeam 113 away from the building wall, its upper surface is provided with a docking slot 1131 with the same structure as the plug-in slot 1221 of the connecting block 122. The end of the crossbeam 113 away from the building wall is also connected to a transverse fixing beam 112. A connecting ear 1132 with a circular perforation is provided on the lower end surface of the end of the cross beam 113 away from the building wall. The connecting ear 1132 is rotatably connected to the inclined mounting beam 114 through bolts.

[0035] The vertical fixed beam 111 has a protruding portion at one end away from the connecting block 122, forming a connecting portion 1112. This connecting portion 1112 is used to securely connect the lower end of the mounting beam 114. The corresponding cover plate 123 is provided with a through-hole 1230 for exposing the connecting portion 1112. The cooperation between the through-hole 1230 and the connecting portion 1112 allows the gravity exerted on the crossbeam 113 to be directly applied to the vertical fixed beam 111, reducing the stress on the connecting block 122. This allows the overall structure to better withstand stress and allows for more accurate installation and fixation when the cover plate 123 is installed. The connecting portion 1112 is provided with an interface 1113. The lower end of the mounting beam 114 is bent to form a bent portion 1141, which is embedded in the interface 1113.

[0036] The baffle 30 is used to block falling dust and serves as a secondary barrier to prevent large debris from falling from the building. It is made of metal or high-strength plastic. Multiple baffles 30 are provided, formed by splicing them together. Specifically, a protrusion 301 is provided on the lower end of the baffle 30, near the end of the transverse fixing beam 112. This protrusion 301 inserts into the groove 1129 of the transverse fixing beam 112 and is then bolted to the transverse fixing beam.

[0037] In addition, a local protrusion is formed at the upper end of the vertical fixed beam 111 to form a mounting protrusion 1115. The mounting protrusion 1115 is a metal protrusion, and a screw hole is provided on the mounting protrusion 1115. A first support rod 1116 is screwed on the mounting protrusion 1115. The support rod 1116 is a metal rod. A first baffle 1117 is inserted into the first support rod 1116. A corner of the safety net 20 is inserted into the first support rod 1116, and then a nut is screwed on to tighten the corner of the safety net 20. A second support rod 1136 is screwed onto one end of the crossbeam 113. A second stopper 1137 is provided on the second support rod 1136. The other end of the safety net 20 is inserted into the second support rod 1136 and then tightened and secured with a nut. Similarly, the first and second support rods on another set of fixed bases tighten the other two corners of the safety net 20, pulling the safety net 20 up and securing it. This installation method is simple and efficient.
