Abstract

The utility model discloses a protection platform foundation structure encorbelments of individual layer, including two spinal branch bedplate of bottom plate and symmetrical welding on the bottom plate, rotate through the round pin axle between two spinal branch bedplate and be connected with the fly leaf, the welding has the backup pad on the fly leaf, and the welding has first takeover perpendicularly in the backup pad, and the welding has the second to take over perpendicularly in one side that lies in the fly leaf on the spinal branch bedplate. The utility model discloses can pass through expansion bolts on-the-spot fixedly to prefabricated mounting and connecting piece in the work progress, avoid pre-buried requirement to the time limit for a project, construction convenience. The construction method is particularly suitable for local and small-range protection construction, flexible in construction, free of space limitation, short in construction period, convenient to dismantle and turnover, and capable of improving construction efficiency.

Description

Single-layer overhanging protection platform foundation structure

Technical Field

The utility model relates to a protection platform foundation structure encorbelments of individual layer belongs to building structure engineering technical field.

Background

In the rapid development process of buildings in China, the protection ratio of the external cantilever frames is adopted in the construction of external structures of some buildings. The traditional external cantilever scaffold measures are high in cost, long in construction period, large in construction difficulty, difficult to transfer and required to be pre-buried in advance. Especially to the part that needs to set up the protection of encorbelmenting a small amount of local, traditional outer cantilever crane sets up with high costs, and the flexibility is not enough.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, simple to operate, can have enough to meet need the individual layer of use and encorbelment protection platform foundation structure to solve the tradition and encorbelment the outrigger not enough problem in the aspect of the construction degree of difficulty and flexibility.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a protection platform foundation structure encorbelments of individual layer, includes two support boards of bottom plate and symmetrical welding on the bottom plate, is connected with the fly leaf through the round pin axle rotation between two support boards, and the welding has the backup pad on the fly leaf, and the welding has first takeover perpendicularly in the backup pad, and the welding has the second takeover perpendicularly in one side that lies in the fly leaf on the support board.

Furthermore, the bolt has all been inserted at the both ends of round pin axle, prevents that the round pin axle is not hard up.

Further, centers of the first connecting pipe and the second connecting pipe are in the same plane.

Furthermore, bolt holes are formed in four corners of the bottom plate, and expansion bolts are inserted into the bolt holes.

Since the technical scheme is used, the utility model discloses an advantage has below: the utility model discloses can pass through expansion bolts on-the-spot fixedly to prefabricated mounting and connecting piece in the work progress, avoid pre-buried requirement to the time limit for a project, construction convenience. The construction method is particularly suitable for local and small-range protection construction, flexible in construction, free of space limitation, short in construction period, convenient to dismantle and turnover, and capable of improving construction efficiency.

Description of reference numerals: 1-expansion bolt, 2-bottom plate, 3-support plate, 4-pin shaft, 5-bolt, 6-support plate, 7-second connecting pipe, 8-first connecting pipe and 9-movable plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides a: referring to fig. 1 and 2, a single-layer overhanging protection platform foundation structure includes a bottom plate 2 and two support plates 3 symmetrically welded on the bottom plate 2, a movable plate 9 is rotatably connected between the two support plates 3 through a pin 4, a support plate 6 is welded on the movable plate 9, a first connecting pipe 8 is vertically welded on the support plate 6, and a second connecting pipe 7 is vertically welded on one side of the movable plate 9 on the support plate 3. The two ends of the pin shaft 4 are inserted with bolts 5, so that the pin shaft 4 is prevented from loosening. The centers of the first adapter tube 8 and the second adapter tube 7 are in the same plane. Bolt holes are formed in four corners of the bottom plate 2, and expansion bolts 1 are inserted into the bolt holes.

During construction, firstly paying off and drilling on a concrete floor slab or a concrete beam, then fixing the bottom plate 2 on the concrete floor slab or the concrete beam through the expansion bolts 1, adjusting the included angle between the first connecting pipe 8 and the second connecting pipe 7 according to the size of the cantilever support, respectively sleeving the steel pipes on the first connecting pipe 8 and the second connecting pipe 7 after adjustment, and fixing the steel pipes through fasteners to complete erection of the cantilever support.
