Description

Technical Field

[0001] The utility model relates to a safety protection device for engineering construction. Background Art

[0002] The elevator shaft is a building structure used to install elevators. Especially for high-rise buildings with more than 7 floors, the vertical height of the elevator shaft is relatively high. When conducting rooftop construction, it is necessary to build protective devices on the outside of the elevator shaft to prevent people from falling into the shaft.

[0003] A common protection method is to build a guardrail on the outside of the elevator shaft. The guardrail is movable and placed on the ground. This protection measure is mainly to prevent staff from getting close. Its warning function is greater than its protective function. When a fall into the shaft accident really occurs, this guardrail will not provide any protection.

[0004] In the prior art, there are also measures to build a protective net in the elevator shaft. In the prior art, building the protective net requires driving expansion bolts on the ground and then anchoring the protective net through the expansion bolts, which causes certain damage to the main body of the building and is relatively troublesome to install and remove.

[0005] Based on the above problems, we designed a construction safety protection device which is easy to build, has good protection effect, and does not damage the building structure. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an engineering construction safety protection device which is easy to build, has a good protection effect and does not damage the building structure.

[0007] The utility model is realized by the following technical solutions:

[0008] A construction safety protection device includes support members arranged at four corners of an elevator shaft, and an adjustable rod component connected between the diagonal support members, a safety net is detachably hung between the four support members, the safety net covers the elevator shaft, and a guard plate is installed between two adjacent support members, the guard plate protects the outside of the elevator shaft.

[0009] Preferably, the support member includes a column, which is a right-angled triangular prism, and more than two threaded holes are arranged on the upper and lower parts of the inclined surface of the column, and a connecting seat is cooperated through the threaded holes, and the adjustable rod member is extended and inserted into the connecting seat, and a bottom plate is arranged on the outer side of the column, and the bottom plate is limited to the ground. When the bottom plate is limited to the ground, the threaded hole is sunk into the elevator shaft, and the upper end of the column extends to the outside of the elevator shaft, and a bolt connected to the safety net is arranged on the top of the column, and the bolt is cooperated with a nut after passing through the safety net, and the top part of the bottom plate is provided with two first bolts, and the first bolt is cooperated with the first nut after passing through the guard plate.

[0010] Preferably, a socket is provided at the end of the connecting seat away from the threaded hole, and a fitting port penetrating to the socket is provided on the outer wall of the connecting seat, the length of the fitting port is smaller than the depth of the socket, and the adjustable rod member is fitted into the socket after passing through the fitting port.

[0011] Preferably, the adjustable rod member comprises a rod, the interior of the rod is hollow, both ends of the rod are fitted with screws, a polygonal force-bearing portion is provided on the body of the screw, and the screw is fitted into the socket from the fitting port.

[0012] Preferably, the safety net includes a woven outer frame and a net body sewn to the inner side of the outer frame, multiple layers of reinforcing cloth are sewn at the corners of the outer frame, the net body is sewn to the reinforcing cloth, and the bolts pass through the reinforcing cloth.

[0013] Preferably, the guard plate includes a plate body, and ear plates are provided at the bottom positions of both ends of the plate body, and the first bolt passes through the ear plates and is fitted into the first nut.

[0014] The beneficial effects of the utility model are:

[0015] Advantage 1: This device is very easy to build. After installing the support parts, it can be tensioned through the adjustable rod components, and finally the protective net and guard plate can be laid. It is easy to install without drilling holes, and it is also easy to dismantle later, which also avoids damage to the building.

[0016] The second advantage is that it has double protection. The outer side is protected by a guard plate to prevent construction workers from getting close to the elevator shaft. When the guard plate is hit and causes failure, secondary protection is provided by a protective net.

[0017] Advantage three: After the adjustable rod components are assembled, they are staggered in an X shape in the elevator shaft, which greatly reduces the risk of falling objects in the elevator shaft. BRIEF DESCRIPTION OF THE DRAWINGS
