The technical features of the embodiments of the utility model can be combined correspondingly on the premise of no mutual conflict.

In the description of the present utility model, it will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected with intervening elements present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In the description of the present utility model, it should be understood that the terms "first" and "second" are used solely for the purpose of distinguishing between the descriptions and not necessarily for the purpose of indicating or implying a relative importance or implicitly indicating the number of features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

As the existing high-rise building is built higher, the number of house layers is increased, if a frame structure is selected, the anti-seismic requirement cannot be met, and frame beams are required to be arranged in the shear wall, so that the anti-seismic effect can be achieved. In the building process, the construction elevator is upwards arranged along with the construction progress. In order to avoid the influence of concrete and raw materials falling on the construction elevator when the concrete pouring operation is carried out above the construction elevator, a protection device is required to be arranged on a frame beam above the construction elevator.

As shown in fig. 1 and 2, in a preferred embodiment of the present utility model, there is provided an in-hoistway construction elevator assembly type protector, which mainly includes two protective side plates 2, a protective middle plate 3, and four scaffold clips 7. In this embodiment, the installation floor of the above-described modular guard is two floors higher than the highest stop floor of the construction elevator in the hoistway. The connection relation and the use method of each component are described in detail below.

The two protection side plates 2 are respectively arranged on two sides above the frame beam 1. The bottom of the protection side plate 2 is bent, and the bending part is attached to the plane of the frame beam 1. The bending part at the bottom of the protection side plate 2 is provided with a plurality of single-hole gaskets 4, and the first fastening piece penetrates through the single-hole gaskets 4 to fix the protection side plate 2 on the frame beam 1. A protective middle plate 3 is arranged between the two protective side plates 2. The bottom of the protection middle plate 3 is bent, and the bending part is also attached to the plane of the frame beam 1. The bottom bending and splicing part of the protection side plate 2 and the protection middle plate 3 is provided with a double-hole gasket 5, and the double-hole gasket 5 spans a gap between the protection side plate 2 and the protection middle plate 3. The first fasteners 6 are respectively installed in the two holes to realize the tight splicing of the protective side plates 2 and the protective middle plate 3, so that the protective side plates 2 and the protective middle plate 3 are arranged on the frame beam 1 in a full-spread mode, and a whole protective device main body structure is formed.

In view of the large load that the connections between the protective side plates 2, the protective middle plate 3 and the frame beam 1 need to carry, expansion bolts are selected as the first fasteners in this embodiment. When the device is used, the impact electric drill or the impact hammer is used for drilling holes with corresponding sizes on the fixed body (namely the frame beam), then the bolts and the expansion pipes are arranged in the holes, and the nuts are screwed, so that the bolts, the expansion pipes, the mounting parts (namely the protection side plates and the protection middle plate) and the fixed body (namely the frame beam) are expanded into a whole.

It should be noted that, if the size of the frame beam 1 is smaller, the two protection side plates 2 can be covered on the frame beam 1 in a full-spread mode after being spliced, and then the protection middle plate 3 is not required to be additionally arranged; if the frame beam 1 is large in size or the elevator shaft to be protected is composed of a plurality of continuous protection shafts, a plurality of protection middle plates 3 can be additionally arranged between the two protection side plates 2 to enlarge the protection range.

In order to make the worker more convenient in high-altitude construction and ensure the smooth construction process, a scaffold 9 is required to be arranged in the elevator shaft. The bottom of the scaffold 9 is fixed on the I-steel of one layer on the highest stop floor of the construction elevator. The I-steel both sides are fixed in elevator well body structure.

The splice at the tops of the protective side plates 2 and the protective middle plate 3 is provided with a circular hole for the scaffold 9 to pass through. In order to ensure that the scaffold 9 can be tightly connected with the protection side plates 2 and the protection middle plate 3, materials such as fine crushed concrete and the like are prevented from falling to damage a construction elevator below, two scaffold clamping pieces 7 are arranged around each circular hole at the splicing position of the tops of the protection side plates 2 and the protection middle plate 3. The two scaffold clips 7 are arranged opposite to each other so that they can wrap the passing scaffold 9. The two scaffold clamping piece sides are fixedly connected through screws. In addition, the bottoms of the two scaffold clamping pieces 7 are bent, and the bent parts of the bottoms cover gaps among the scaffold 9, the protective side plates 2 and the protective middle plate 3.

In order to further ensure the tightness of the whole assembly type protective device, the joints of the protective side plates 2, the protective middle plate 3 and the scaffold clamping pieces 7 and the joints of the protective side plates 2, the protective middle plate 3 and the frame beam 1 are plugged by waterproof sealing materials. In this embodiment, the sealant is selected as a waterproof sealing material for sealing. However, the waterproof sealing material is not required in this embodiment, and materials such as a sealing rubber strip, a building sealing paste, a foam plug, and a rubber gasket may be selected.

Under the condition that the main body structure is a frame beam, the assembly type protection device is arranged. If the frame beam 1 structure is replaced by a shear wall structure, the protection effect on the construction elevator can be realized, and only the bottom bending of the protection side plate 2 and the protection middle plate 3 is canceled, and the side edges of the protection side plate 2 and the protection middle plate are directly fixedly connected with the edge of the shear wall through fasteners.

The split mounting type protection device provided by the embodiment is convenient and simple to install and detach, can be matched with elevator shafts of various sizes, can be recycled and reused, and can improve construction efficiency. And the protection device is tightly connected with the main body structure, the gaps are blocked by waterproof materials, the whole engineering is completed by common workers, and the waterproof construction is reduced.

The above embodiment is only a preferred embodiment of the present utility model, but it is not intended to limit the present utility model. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present utility model. Therefore, all the technical schemes obtained by adopting the equivalent substitution or equivalent transformation are within the protection scope of the utility model.
