Technical Field

The invention relates to the technical field of building construction, and particularly discloses an integral prefabricating and forming structure of a tower crane embedded part and a core cylinder reinforcing mesh.

Background

A swing arm tower crane (a tower crane for short) is important construction equipment for super high-rise building construction and is mainly used for solving the problem of vertical transportation of materials in construction. The supporting mode of the tower crane comprises an inner climbing mode and an outer attaching mode, and the two methods are used in high-rise buildings very much. The internal climbing type tower crane and the external attached type tower crane do not occupy a construction site, are suitable for on-site narrow engineering, do not need to lay a track, do not need to specially manufacture a reinforced concrete foundation, and have very remarkable economic benefit.

The embedded parts used by the internal climbing type tower crane and the external attached type tower crane are reliably connected with a concrete wall, wherein the embedded parts generally comprise two internal anchor plates and a plurality of anchor bars, and two ends of the anchor bars are horizontally welded on the two internal anchor plates respectively. In traditional construction, before installing the embedded part, need earlier the ligature core section of thick bamboo reinforcing bar net, the reinforcing bar net includes vertical muscle, horizontal muscle and vertical horizontal muscle, treats that the reinforcing bar net ligature reaches the embedded part scope, puts into the reinforcing bar net and fixes interior anchor slab from vertical muscle top, then continues ligature horizontal muscle. The scheme has a plurality of defects which are mainly reflected in that: 1. the embedded parts are installed manually on site, so that the requirement on positioning accuracy is high, time and labor are wasted in manual installation, and the labor cost is high; 2. the transverse horizontal ribs close to the inner anchor plate part cannot penetrate through the inner anchor plate and can only be cut off, so that the local strength of the wall body is reduced; 3. the installation of the transverse horizontal ribs between the two inner anchor plates is troublesome, the transverse horizontal ribs need to penetrate through the anchor ribs one by one, the hands of installation workers cannot stretch into the anchor ribs and are influenced by the vertical ribs, so that the operations of binding on site, installing a sleeve and the like are very difficult; 4. when the device is installed manually, the positioning precision is poor due to the influence of the experience of workers and complex reinforcing meshes; 5. after the traditional embedded part is installed and used, the embedded part cannot be dismantled for repeated use, and the economical efficiency is poor.

Disclosure of Invention

The invention aims to provide an integral prefabricating and forming structure of an embedded part and a core cylinder reinforcing mesh of a tower crane, so as to solve the problem of low manual field installation efficiency.

In order to achieve the purpose, the basic scheme of the invention is as follows:

tower machine built-in fitting and the whole prefabricated forming structure of core section of thick bamboo reinforcing bar net, including reinforcing bar net structure and built-in fitting, the reinforcing bar net structure includes vertical muscle, horizontal muscle and vertical horizontal muscle, the built-in fitting includes anchor slab and a plurality of anchor muscle in two blocks, the anchor muscle includes horizontal portion and longitudinal part, horizontal portion and longitudinal part are all leveled, and horizontal portion and longitudinal part vertically and horizontally staggered connect and form netted, horizontal portion and adjacent horizontal muscle fixed connection, interior anchor slab and adjacent vertical horizontal muscle or horizontal muscle fixed connection.

optionally, the longitudinal section of the outer wall of the clamping groove part is in a right trapezoid shape, and the inclined surface of the outer wall faces downwards.

The working principle and the beneficial effects of the scheme are as follows:

1. the steel bar net structure in the scheme is a steel bar integral framework of the core tube wall body, the steel bar net structure and the embedded parts are prefabricated and formed in a factory, and the core tube wall body can be formed by directly transporting the steel bar net structure to a site and then hoisting, supporting templates and pouring concrete, and the part needing manual installation on the site is few, so that the construction time is greatly shortened, and the construction efficiency is improved.

2. In the prior art, the embedded part has large overall mass, high price and difficult transportation due to a plurality of anchor bars and heavy anchor plates; the anchor plate in this scheme includes interior anchor plate and outer anchor plate, and interior anchor plate thickness is less than outer anchor plate, and outer anchor plate can be dismantled and reuse from interior anchor plate, so need not to set up outer anchor plate again during the installation of other built-in fittings, and the whole quality of built-in fittings reduces, and has saved the material cost of outer anchor plate portion, and the price also descends to some extent.

3. In the prior art, when the embedded part is installed on site, anchor bars on the embedded part are generally bound on adjacent vertical bars by workers, and the height positioning needs a jig frame, so that the operation is troublesome, time-consuming and labor-consuming. The product prefabricated and molded in a factory has high positioning precision, in the scheme, the height of the vertical rib of the outer side part is controlled only, then the second sleeve on the inner anchor plate is aligned to the vertical rib of the part, and the second sleeve and the vertical rib are fixedly installed without binding or a jig frame; meanwhile, vertical ribs are cut off more conveniently and accurately in a factory, and the efficiency of the whole installation process is very high.

4. The anchor bars in the scheme are of a net structure, the transverse parts in the anchor bars can replace transverse horizontal bars, the longitudinal parts can replace longitudinal horizontal bars, and the transverse parts are connected with the adjacent transverse horizontal bars through the first sleeves, so that the connection mode is simple and firm, the transverse horizontal bars and the longitudinal horizontal bars do not need to be installed between the two inner anchor plates, and the installation efficiency is higher;

5. the second sleeve is arranged on the triangular block, and the stress condition of the triangular block can be improved.

6. The hollow part and the clamping block of the clamping groove part are both in a right trapezoid shape, the clamping groove is in a right trapezoid shape, the inclined surface of the clamping groove faces downwards, and the stress condition can be improved.
