Background
In the construction of steel structures, steel members are generally transported to a construction site by a member transporting vehicle, and then unloaded from the site by using a tower crane or a large crane. However, the column bottoms of the first-section columns of the steel structures are provided with large column foot plates, the column foot plates are large in specification and size and large in plate thickness, and the column foot plates are not provided with hoisting lugs generally. Taking the second-stage steel structure engineering of Tianjin digital television mansion as an example, the largest section of the first section of steel column is 1200 × 1200 × 30 × 30 of a box opening, the largest thickness of a column foot plate is 100mm, and the steel column can not be unloaded by adopting conventional snap rings, shackles and the like.
At present, when most projects unload the first section of column on site, the conventional snap ring cannot penetrate through the column foot plate due to the large thickness of the column foot plate, and the unloading is usually carried out by adopting a binding type method (commonly called as holding and hanging). As shown in figure 1, before unloading, four rubber wrap corners or corner-free wrap corners 40 are prepared in advance to protect the steel wire rope 10, and then an on-site tower crane is adopted to unload. There are: when the steel wire rope binds the steel column 20, the corner angle of the steel column needs to be protected; the steel wire rope is easily scratched by the edge of the steel column, so that potential safety hazards exist; when unloading, need to pass wire rope from the steel column bottom to set up flitch 30 at the bottom of steel column, waste unloading time scheduling problem relatively.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an anchor clamps for on-spot unloading of steel construction first section post, can conveniently hang on the bolt hole of column base, conveniently hoist the first section post that is equipped with large-scale toe board to solve current bundling method hoist first section post security poor, long problem consuming time.
In order to solve the technical problem, the utility model provides an anchor clamps that are used for on-spot unloading of steel construction first section post, include:
the clamp comprises a clamp body, a bolt and a lifting lug; wherein,
the lifting lug is arranged at the top of the clamp body;
the clamp body is provided with an open slot, the opening of the open slot is positioned at the bottom end of the clamp body, and a bolt hole is formed in the clamp body at the opening;
the bolt is arranged in the bolt hole of the clamp body.
The utility model has the advantages that: the open slot and the bolt cooperation through the anchor clamps body for the first section post of handling steel construction that can be convenient, safety is improved to the first section post handling of steel construction, the efficiency of unloading on the bolt hole of the large-scale toe board of first section post is installed to anchor clamps can be convenient, the lug on the anchor clamps body is utilized. The lifting appliance has simple structure and safe and convenient use.

Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of 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 invention provides a clamp for field unloading of a first section of steel structure column, which comprises the following components in parts by weight as shown in figures 2 and 3: the clamp comprises a clamp body 1, a bolt 3 and a lifting lug 2;
wherein the top of the clamp body 1 is provided with a lifting lug 2;
the clamp body 1 is provided with an open slot 11, the opening of the open slot 11 is positioned at the bottom end of the clamp body 1, and a bolt hole 12 is arranged on the clamp body 1 at the opening;
the plug pin 3 is arranged in the plug pin hole 12 of the clamp body 1.
Among the above-mentioned anchor clamps, anchor clamps body 1 adopts the thick steel sheet of 30mm to bend into lower extreme opening, upper end confined n style of calligraphy, and the open slot setting is at the middle part of anchor clamps body, and the open-ended width of the open slot of this anchor clamps body is 70 ~ 110mm, specifically with column foot board thickness phase-match can.
In the above-mentioned anchor clamps, bolt 3 adopts M30 round steel to make, and 3 both ends of bolt are equipped with the screw thread, all are equipped with nut 31 on the screw thread at 3 both ends of bolt.
