Description

Detachable elevator shaft protection support frame

Technical Field

The utility model belongs to the technical field of building construction tools, and particularly relates to a protective support frame for electricity.

Background

In the construction process of the elevator shaft, intermediate layer unloading is required, and when the support body is erected to exceed 20m, the support body foundation needs to be additionally arranged. The common method is to pre-embed through-length I-steel on the floor needing to increase the frame foundation, wherein two ends of the I-steel extend out of the shear wall and are provided with an anchoring section, and the frame foundation are dismantled after the follow-up brick masonry and painting are finished. The I-steel that traditional way used is more, and leaves on the shear force wall and establish the entrance to a cave, and later stage is demolishd and is moved back comparatively difficultly, and work load is big, and the I-steel stretches out outside the shear force wall simultaneously, influences the traffic, brings the puzzlement for the construction.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a support frame which is small in size, convenient to use, easy to disassemble and capable of meeting the protection requirement of an elevator shaft.

The purpose of the utility model is realized by the following technical scheme:

the utility model provides a can dismantle elevartor shaft protection support frame, install four support element on the relative both sides wall of a well in the elevartor shaft including the symmetry, every support element includes the horizontal braces, weld in the first end plate of horizontal braces outer end, set up the diagonal braces below the horizontal braces, weld in the diagonal braces lower extreme and be located the second end plate on same vertical wall with first end plate, pre-buried respectively in the elevartor shaft and respectively with first end plate and second end plate fixed connection's buried bolt in advance, weld in the diagonal braces top and paste and lean on the third end plate in the horizontal braces bottom surface, connect the connecting bolt of third end plate and horizontal braces, weld in the vertical locating pin of horizontal braces top surface.

Furthermore, the embedded bolt comprises a steel turning wire sleeve, at least three horizontal hooks uniformly distributed and welded along the outer wall of the steel turning wire sleeve and hung on a steel bar hook in the shaft wall of the elevator shaft, and a bolt assembled in the steel turning wire sleeve.

Further, horizontal brace and diagonal bracing are the I-steel member.

The utility model utilizes a stress system formed by the horizontal support and the oblique support and is arranged in the elevator shaft in a simple connection mode of connecting the support units by the embedded bolts, thereby avoiding the problems of forming holes on the shear wall of the elevator shaft wall, and the problems of large using amount of I-steel, influence on traffic and construction due to the fact that the I-steel is too long and exceeds the range of the elevator shaft when the I-steel is used.

The utility model has the advantages of simple structure, stability, reliability, easy disassembly and assembly, convenient use, low manufacturing cost, repeated use, economy, practicability and higher application value.

Detailed Description

The utility model is further explained by the accompanying drawings.

As shown in fig. 1 and 2, the detachable elevator shaft protective support frame of the utility model comprises four support units symmetrically installed on opposite side shaft walls in an elevator shaft, wherein each support unit comprises a horizontal support 1, a first end plate 2 welded at the outer end of the horizontal support, an inclined support 4 arranged below the horizontal support, a second end plate 5 welded at the lower end of the inclined support and positioned on the same vertical wall surface with the first end plate, embedded bolts 3 respectively embedded in the elevator shaft wall and fixedly connected with the first end plate and the second end plate, a third end plate 6 welded at the top end of the inclined support and attached to the bottom surface of the horizontal support, connecting bolts 8 connecting the third end plate and the horizontal support, and vertical positioning pins 7 welded on the top surface of the horizontal support. The horizontal support 1 is an I-shaped steel member directly cut by I-shaped steel, the inclined support 4 can be directly cut by I-shaped steel, steel plates, channel steel, steel pipes and the like, the top surface of the inclined support 4 is a horizontal end surface, and the third end plate 6 is horizontally welded on the horizontal end surface; the lower end face of the inclined support 4 is a vertical end face, and the second end plate 5 is vertically welded on the vertical end face. The diagonal support 4 may be made of steel plate, channel steel, or steel pipe.

As shown in fig. 3, the embedded bolt comprises a steel threading sleeve 3-3 for threading an inner hole, at least three steel bar hooks 3-1 which are uniformly distributed and welded along the outer wall of the steel threading sleeve and are horizontally hooked in the shaft wall of the elevator shaft, and a bolt 3-2 which is arranged in the steel threading sleeve.

When the steel wire rope support is used, the steel bar hook 3-1 of the embedded bolt 3 and the steel wire rope sleeve 3-3 are installed in the concrete shaft wall of the elevator shaft 9 in advance, concrete pouring and maintenance are completed, then the four support units are installed respectively, the first end plate 2 and the second end plate 5 are both provided with installation holes in advance, the bolts 3-2 penetrate through the first end plate 2 and the second end plate 5 respectively and are screwed into the steel wire rope sleeve 3-3, and therefore the support units can be stably installed on the shaft wall of the elevator shaft. Then can insert four stands of elevartor shaft construction support body 10 on four support element's reference column round pin respectively, the support of elevartor shaft construction support body is realized to convenient and fast ground. After the construction is finished, the construction frame body is taken out, the bolts 3-2 and the connecting bolts 8 are disassembled, and the horizontal supporting member and the oblique supporting member can be disassembled and can be repeatedly used.
