CN203807009U - Bent bar anchorage structure for attachment of tower crane in high-rise building construction - Google Patents

Abstract

The utility model discloses a bent bar anchorage structure for the attachment of a tower crane in high-rise building construction. The bent bar anchorage structure comprises an anchor plate, wherein a plurality of bent steel bars are welded to one side of the anchor plate in parallel, and the bent steel bars are in the shapes of curves in a plane. The bent bar anchorage structure provided by the utility model has the advantages that a distance that the bent steel bars are penetrated into concrete is small, so that influence on the configuration of inherent steel bars of the structure is small; the shapes of the bent steel bars can be properly modified according to the actual situation of the layout of the structure steel bars, the structure steel bars can be effectively kept away, and the flexibility in actual operation is strong; in the process of casting, the concrete can penetrate through gaps in the bent steel bars, concrete tenons can be formed after the concrete is solidified, and the shear resistance and the pulling-drawing resistance performance of the structure are further improved.

Description

A kind of high-building construction tower crane adheres to uses bent bar anchorage structure

Technical field

The utility model relates to high-building construction field, is specifically a kind ofly for high-building construction tower crane, to adhere to anchor structure.

Background technology

At present, known in housing construction process concrete structure and interim measures such as tower crane etc. be connected adopted anchor structure be according to < < Code for design of concrete structures > > GB50010-2010 in the embedded bar anchoring process of defined, be reinforcing bar one end and Plate Welding, and integral built-in is in cement concrete, plays the anchorage effect to structure.The required reinforcing bar length of this form of construction work is longer, in Embedment Construction, to have influence on the laying of structure self reinforcing bar, anchor slab size is subject to the impact of anchor bar quantity large, and the bearing capacity of anchor structure is also subject to the restriction of the many factors such as reinforcing bar anti-pulling intensity, anchor slab intensity and welding quality, the load-carrying properties of anchor structure can not have been given play to greatest extent.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of strong on alerting ability in little, the practical operation of impact of arranging of the intrinsic reinforcing bar of structure, further improve the shear resistance of structure and a kind of high-building construction tower crane of anti-pulling performance and adhere to and use bent bar anchorage structure.

A kind of high-building construction tower crane of the present utility model adheres to uses bent bar anchorage structure, and it comprises anchor slab, is welded with a plurality of moment reinforcements a side of described anchor slab is parallel, and described moment reinforcement adopts plane introversion linear.

The utility model has the advantage of:

1, to go deep into cement concrete middle distance little for moment reinforcement, little on the impact of arranging of the intrinsic reinforcing bar of structure;

2, the actual conditions that the shape of moment reinforcement can be arranged according to structure reinforcing bars are suitably revised, and can effectively avoid structure reinforcing bars, and in practical operation, alerting ability is strong;

3,, in casting process, cement concrete can form cement concrete tenon after solidifying by the gap of moment reinforcement, further improves shear resistance and the anti-pulling performance of structure;

4, the tensile characteristics of curved muscle can, by Shear transfer to steel structure, improve structural entity load-carrying properties;

5, this steel plate can be used as anchor slab use, can on steel plate, add the structures such as bracket, can be applicable to various structures, and applicability is strong.

The specific embodiment

Referring to accompanying drawing, the specific embodiment of the present utility model is described further.

A kind of high-building construction tower crane of the present utility model adheres to and uses bent bar anchorage structure as shown in drawings, and it comprises anchor slab 2, is welded with a plurality of moment reinforcements 1 a side of described anchor slab is parallel, and described moment reinforcement adopts plane introversion linear.

Embodiment:

A kind of high-building construction adheres to anchor structure (Fig. 1-5) with tower crane.It comprises that moment reinforcement 1, anchor slab 2, moment reinforcement 1 are welded on anchor slab 2.Moment reinforcement adopts plane introversion linear, during anchoring piece work, can on anchor slab 2, weld the structures such as bracket 4, and while building, cement concrete can form cement concrete tenon by the space between moment reinforcement.Reinforcing bar is by the suffered shearing of its tensile structure characteristic conducting structure.

Claims (1)

1. high-building construction tower crane adheres to and uses a bent bar anchorage structure, and it comprises anchor slab, it is characterized in that: be welded with a plurality of moment reinforcements a side of described anchor slab is parallel, described moment reinforcement adopts plane introversion linear.
