They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] The utility model provides a protective device for a cap beam. Through the integrally assembled protective bracket and protective components, it is only necessary to extend the protective device and fix it on the beam cap at the construction site. The operation is convenient and the safety performance is better.

[0030] Specific as Figure 1 As shown, the protective device for the cap beam includes a protective bracket and a protective assembly. The protective bracket is used to serve as the main rigid frame of the protective device, and the protective assembly is installed on the protective bracket to ensure the safety of construction workers on one side of the protective bracket.

[0031] like Figure 1 , Figure 2 As shown, the protective bracket has two vertical support rods 1 arranged relatively parallel to each other. When installed, the vertical support rods 1 are used to be arranged vertically on the upper surface of the cap beam. A horizontal connecting beam 2 is fixedly connected between the two vertical support rods 1. Fixing members 3 are respectively arranged at the bottom ends of the two vertical support rods 1. The fixing members 3 are used to connect the cap beam. The specific fixing members 3 are rod-shaped structures. The connecting screws 8 are passed through the fixing members 3, and the connecting screws 8 are directly fixed on the cap beam to fix the protective bracket on the cap beam. When the protective bracket is fixed to both ends of the cap beam, the connecting screws 8 pass through the fixing members 3 horizontally, so that when the protective bracket is installed on the cap beam, the connecting screws 8 are fixedly connected to the two side walls of the cap beam; the connecting screws 8 can also be arranged vertically, that is, installed in the direction parallel to the vertical support rods 1, so that when the protective bracket is installed on both sides of the cap beam, the connecting screws 8 are fixedly connected to the top wall of the cap beam.

[0032] like Figure 1 , Figure 3 As shown, the protection assembly includes a first stopper 4 and a second stopper 5. The first stopper 4 is connected between the two vertical support rods 1 and is in the shape of a plate. The second stopper 5 is connected between the two vertical support rods 1 and is in the shape of a chain. In this way, the first stopper 4 and the second stopper 5 form a double protection barrier to ensure the safety of construction workers on the cap beam. In this embodiment, the width of the first stopper 4 can be set to be the same as the height of the vertical support rod 1, which can better ensure the safety of the device and prevent the risk of construction tools falling during construction.

[0033] Furthermore, in order to enable the device to adapt to cap beams of different sizes, the transverse connecting beam 2 has a telescopic structure for adjusting the distance between the two vertical support rods 1, thereby adjusting the protection range.

[0034] Specifically, the telescopic structure includes a connecting sleeve 201, a telescopic rod 202 and a limiting structure 203. The telescopic rod 202 is partially sleeved in the connecting sleeve 201 and slidably cooperates with the connecting sleeve 201. The limiting structure 203 is used to limit the connection position of the connecting sleeve 201 and the telescopic rod 202.

[0035] In this embodiment, there are two telescopic rods 202, one end of each of the two telescopic rods 202 is fixedly connected to a vertical support rod 1, and the other end of each of the two telescopic rods 202 extends into one end of a connecting sleeve 201. In other embodiments, the telescopic structure may have only one telescopic rod 202 and one connecting sleeve 201, the telescopic rod 202 is fixedly connected to one of the vertical support rods 1, the connecting sleeve 201 is fixedly connected to the other vertical support rod 1, and the telescopic rod 202 and the connecting sleeve 201 are slidably matched.

[0036] In this embodiment, the limiting structure 203 includes a stop screw and a nut, and both ends of the connecting sleeve 201 are respectively provided with through holes 2011 for the stop screw to pass through. The telescopic rod 202 is provided with a plurality of limiting holes 2021 arranged along the length direction of the telescopic rod 202. The stop screw passes through the through hole 2011 and one of the limiting holes 2021 to limit the connection position of the connecting sleeve 201 and the telescopic rod 202.

[0037] In this way, when adjusting the distance between the two vertical support rods 1, the limiting structure 203 can be removed first, and then the telescopic rod 202 can be slid to a suitable position along the connecting sleeve 201, and the stop screw can be passed through the through hole 2011 and one of the limiting holes 2021, and the stop screw can be fixed to the connecting sleeve 201 by installing the nut.

[0038] Further, in order to facilitate the transportation and storage of the device, the fixing member 3 is hinged to the vertical support rod 1. In this way, when in use, the fixing member 3 can be rotated to a suitable position, and after use, the fixing member 3 can be folded to reduce the space occupied by the device.

[0039] Furthermore, in order to ensure the connection stability between the vertical support rod 1 and the fixing member 3, a reinforcing connecting rod 6 is provided between the vertical support rod 1 and the fixing member 3, one end of the reinforcing connecting rod 6 is connected to the vertical support rod 1, and the other end is detachably connected to the fixing member 3.

[0040] In this embodiment, the first stopper 4 is a telescopic plate or a safety net or a marking cloth. To facilitate the removal and replacement of the first stopper 4 , the first stopper 4 is connected to the vertical support rod 1 by a clamping arrangement.

[0041] Specifically, fixing plates 7 are provided at both ends of the first stop member 4. The fixing plates 7 are in the shape of an elongated strip and are arranged along the width of the first stop member 4. A dovetail-shaped fixing strip 701 is provided on the fixing plate 7. The fixing strip 701 is arranged along the length extension direction of the fixing plate 7. Accordingly, a fixing groove 101 adapted to the shape of the fixing strip 701 is provided on the vertical support rod 1 for clamping the fixing strip 701.

[0042] In this embodiment, the second stopper 5 is a chain, and a plurality of chains are provided, and the chain is detachably connected to the vertical support rod 1 through a movable buckle 9 provided on the vertical support rod 1. Figure 4 .

[0043] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
