Abstract
A U-shaped anchor bolt fixing device of an overhanging steel beam comprises a fixing device body and protection tubes arranged at two ends of the fixing device body. The fixing device body comprises round tube portions with two ends protruded and a bridge connection portion connected between the two round tube portions, a cavity without bottom face is arranged under the bridge connection portion and the round tube portion, and the outer surface on the upper half portion of the round tube portions is respectively provided with a water stopping strip which expands when meeting water. The protection tubes are arranged on the upper portions of the round tube portions. The U-shaped anchor bolt fixing device of the overhanging steel beam is simple in design, convenient to produce, low in cost and capable of being recycled and utilized, greatly saves steel material using quantity, and has the good benefits of saving cost and energy and reducing emission.
Description
Technical field
The utility model belongs to the fixing of the provisional shaped steel U-shaped crab-bolt of encorbelmenting such as the shaped steel builder's jack, tool-type discharging platform of the use in the cantilever steel girder anchoring engineering field, particularly building structure construction process.
Background technology
Change in the city in modern times; Because the nervous depth of building in soil is growing; Interim cantilevered structure such as shaped steel builder's jack and tool-type discharging platform is widely used in the engineering construction process, and the U-shaped crab-bolt that its anchoring of encorbelmenting is adopted is embedded in the cast-in-place concrete structure, when removing interim cantilever steel girder, often adopts high energy gas to cut; The U-shaped crab-bolt can only once be used, and has caused a large amount of wastes.Therefore invent and a kind of the device that the U-shaped crab-bolt can be had enough to meet the need utilization again is very important.
The utility model content
The utility model proposes a kind of cantilever steel girder U-shaped crab-bolt fixator for addressing the above problem.
The technical scheme of the utility model is:
A kind of cantilever steel girder U-shaped crab-bolt fixator; This fixator comprises retainer body and the casing that is positioned at the body two ends; Described retainer body comprise two ends projection cylindrical portion and be connected two bridge parts between the cylindrical portion; The bottom of described bridge part and cylindrical portion is the cavity that does not have the bottom surface, and the external surface of the first half of described cylindrical portion is provided with the water-swellable sealing rod; Described casing is arranged on the top of cylindrical portion.
The part of described water-swellable sealing rod is embedded in the external surface of cylindrical portion.
The upper surface of described cylindrical portion is provided with interior stepped hole, the diameter of the diameter of stepped hole and described casing coupling in this.
Described retainer body is to be made by cement mortar, and external surface is a hair side.
The bottom of described retainer body is provided with outside edge, and this edge is provided with screw hole.
The beneficial effect of the utility model:
This shaped steel encorbelment U-shaped crab-bolt fixator simplicity of design, produce conveniently, with low cost, making shaped steel encorbelment the U-shaped crab-bolt can recycling, has practiced thrift the steel use amount in a large number, has played the good benefit of saving cost and energy-saving and emission-reduction.

The specific embodiment
Referring to Fig. 1-Fig. 7; A kind of cantilever steel girder U-shaped crab-bolt fixator among the figure; This fixator comprises retainer body and the casing that is positioned at the body two ends; Described retainer body comprise two ends projection cylindrical portion and be connected two bridge parts between the cylindrical portion, the bottom of described bridge part and cylindrical portion is the cavity that does not have the bottom surface, the external surface of the first half of described cylindrical portion is provided with the water-swellable sealing rod; Described casing is arranged on the top of cylindrical portion.The part of described water-swellable sealing rod is embedded in the external surface of cylindrical portion.The upper surface of described cylindrical portion is provided with interior stepped hole, the diameter of the diameter of stepped hole and described casing coupling in this.Described retainer body is to be made by cement mortar, and external surface is a hair side.The bottom of described retainer body is provided with outside edge, and this edge is provided with screw hole.
Use is following:
On template, eject the shaped steel U-shaped crab-bolt centralized positioning line of encorbelmenting; The shaped steel U-shaped crab-bolt of encorbelmenting is inserted in the fixator, inserted U-shaped crab-bolt casing, screw in the fixed by nut casing, forms an assembly, aligning bolt centralized positioning line is placed on the template, hammers into iron nail and fixes;
Use plastic sheeting or autocratic protective sleeve to protect binding structure reinforcing bar after the U-shaped crab-bolt silk mouth section, and add the crab-bolt anchor bar, accomplish structural concrete and build;
On structural concrete strength reaches, after people's operation standard, reclaim U-shaped crab-bolt protection sleeve, the shaped steel of fixedly encorbelmenting is exercised the shaped steel function of encorbelmenting;
During dismounting, the shaped steel of dismantling earlier takes out the shaped steel U-shaped crab-bolt of encorbelmenting again from the structure bottom.
