Description

A kind of novel elevator hoistways lift-type diagonal brace operation steel platform
Technical field
The utility model relates to a kind of novel elevator hoistways lift-type diagonal brace operation steel platform, particularly builds the structure construction at elevator hoistways place, and its operating platform design and application belongs to technical field of building construction.
Background technology
Along with development of construction, increasing high level and super highrise building have appearred, the elevator shaft excessive height, for construction operation brings potential safety hazard, this has brought greatly challenge also for construction and safety.
Elevator shaft position in the common highrise building, often because elevator shaft headroom size is narrow and small, highly large and without work plane, the difficulty of constructing is larger, common processing way is to utilize scaffold building safe construction platform, though this job practices can satisfy the construction needs, limitation is also apparent.All need to set up in advance scaffold before each construction, during to certain altitude, can only rely on the resistance of elevator shaft both sides shear wall and steel pipe jacking to do the strong point, and also need remove after structure construction is finished, this just causes the material of consumption many, labour cost increases, the cost of security protection aspect is also more.Because the elevator shaft operating platform set up of steel pipe, scaffolding height is higher, is prone to up and down vertical rod out of plumb in addition, drawknot, shores not in placely, and support body is unstable, caves in easily, falling accident.
Summary of the invention
The purpose of this utility model provides a kind of novel elevator hoistways lift-type diagonal brace operation steel platform, greatly made things convenient for the construction in the high-rise building elevator shaft, the utility model has reduced difficulty and the intensity of constructing, construction speed is fast, construction cost is low, workmanship is high, is particularly useful for the construction in the high-rise building elevator shaft.
The technical solution of the utility model is:
A kind of novel elevator hoistways lift-type diagonal brace operation steel platform, comprise steel plate, two girders, two secondary beams, four frame square steel pipes, two diagonal braces, two vertical rods, a horizontal support, two limit components, it is characterized in that: two parallel placements of girder, two secondary beams are welded on respectively on two girders and become groined type, four frame square steel pipes are welded on respectively two girders, form quadro frame on two secondary beam limits, Plate Welding is on quadro frame, two vertical rod one ends are welded on respectively on the bottom surface of two girders and secondary beam intersection, every corresponding vertical rod of diagonal brace, two diagonal braces are welded on respectively on two girder other ends, and every diagonal brace welds together with the bottom of corresponding vertical rod, limit component of bottom welding of every diagonal brace, horizontal support of welding between two diagonal braces.
The utility model also comprises two suspension ring, and two suspension ring are welded on respectively on two girders and pass steel plate.After this layer structure construction is complete, adopt tower crane that operation steel platform of the present utility model handling to last layer is continued construction.
The length of described steel plate is elevator shaft headroom length-100mm, and wide is elevator shaft clearance breadth-100mm, and reserving 100mm is to guarantee that operation steel platform of the present utility model freely promotes.Described steel plate is the thick checkered plates of 3mm.
Limit component is fixed on lower one deck structure operation steel platform of the present utility model sidesway not to occur, play fixation.
Operation steel platform surface layer of the present utility model adopts the thick checkered plates welding of 3mm to be assemblied to form steel plate and the whole full welds of secondary beam contact.
The utility model adopts a kind of novel elevator hoistways lift-type diagonal brace operation steel platform, utilize lower one deck structure to do the strong point, for superstructure construction provides operating platform, construct and utilize tower crane handling to last layer to continue construction after complete, thus can Reusability.This novel diagonal brace operation steel platform is guaranteed construction layer operating personnel's safety, can obviously shorten the activity duration, and the trouble of scaffold building is increased work efficiency when reducing the elevator shaft structure construction.
The utility model has the advantages that, according to this construction of lift well job platform, not only can reduce difficulty of construction, improve speed of application, guarantee construction quality and safety, and save the input of labour and material, reduce cost, therefore, have obvious economic benefit, promotional value is arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the floor map that the utility model is removed the construction steel platform of steel plate.
Fig. 3 is that Fig. 2 adds the A of upper steel plate to view.
At Fig. 1 light plate 1, secondary beam 2, suspension ring 3, frame square steel pipe 4, girder 5, diagonal brace 6, vertical rod 7, horizontal support 8, limit component 9.
The specific embodiment
By reference to the accompanying drawings the utility model is described in detail:
Such as Fig. 1, Fig. 2, shown in Figure 3,
A kind of novel elevator hoistways lift-type diagonal brace operation steel platform, comprise steel plate 1, two suspension ring 3, two girders 5, two secondary beams 2, four frame square steel pipes 4, two diagonal braces 6, two vertical rods 7, a horizontal support 8, two limit components 9, described steel plate 1 is the thick checkered plates of 3mm, the length of steel plate 1 is elevator shaft headroom length-100mm, wide is elevator shaft clearance breadth-100mm, suspension ring 3 are the A20 suspension ring, and girder 5 is 12.6 #Channel-section steel, secondary beam 2 is the square steel pipe of 50 mm * 50 mm * 6 mm, frame square steel pipe 4 is the square steel pipe of 50 mm * 50 mm * 6 mm, diagonal brace 6 is 12.6 #I iron, vertical rod 7 are the square steel pipe of 50 mm * 50 mm * 6 mm, and horizontal support 8 is the square steel pipe of 50 mm * 50 mm * 6 mm, and limit component 9 is 12.6 #I iron; Two girder 5 parallel placements, two secondary beams 2 are welded on respectively on two girders 5 and become groined type, four frame square steel pipes 4 are welded on respectively two girders 5, form quadro frame on two secondary beam 2 limits, steel plate 1 is welded on the quadro frame, two vertical rod 7 one ends are welded on respectively on the bottom surface of two girders 5 and secondary beam 2 intersections, every diagonal brace 6 corresponding vertical rods 7, two diagonal braces 6 are welded on respectively on two girder 5 other ends, and every diagonal brace 6 welds together with the bottom of corresponding vertical rod 7, limit component 9 of bottom welding of every diagonal brace 6, a welding horizontal support 8, two suspension ring 3 are welded on respectively on two girders 5 and pass steel plate 1 between two diagonal braces 6.After this layer structure construction is complete, adopt tower crane that operation steel platform of the present utility model handling to last layer is continued construction.
