Description

Lapper for transverse reinforcement of underground diaphragm wall

The invention relates to a steel bar lapping device, in particular to a horizontal steel bar lapping device for an underground continuous wall.

The underground diaphragm wall is a common soil retaining method. It is an underground reinforced concrete wall that surrounds the surroundings of the underground structure to be excavated. Then, when excavating, the outer soil and groundwater will not collapse and infiltrate into the base, and can be smoothly excavated. To build the foundation of the underground structure, in addition to the above functions, the diaphragm wall can also be used as the outer wall of the underground structure and become a part of the main structure.

At present, the domestic diaphragm wall construction is not only used as a soil retaining facility, but also provides the structural system of the underground structure. Therefore, it is necessary to pre-embed the steel bars at the ground beams or the floor slabs of the underground floors. However, the strength of the steel bars may be reduced after being bent many times, affecting the overall structure, so there is still considerable room for improvement. In view of this, the creators worked hard and devoted themselves to research, and finally completed the creation of the horizontal steel bar lapper for the underground diaphragm wall in this case to overcome the lack of conventional technology.

The main purpose of this creation is to provide an underground continuous wall transverse steel bar lapper, which can maintain the strength of the extended steel bar and make the overall structural strength stable.

Another purpose of this creation is to provide a horizontal steel bar lapping device for underground diaphragm walls, which is fast and convenient in its joining method, greatly reduces the difficulty of construction and is fast in construction.

In order to achieve the above-mentioned purpose, this work is an underground continuous wall horizontal steel bar lapping device, which includes a fixed part and an extension part. The fixed part is arranged on a steel bar structure. The material of the fixed part can be, for example, steel, but It is not limited to this; one end of the fixed part has a fixed end that can be fixed on the steel structure, the fixed end is a disc part, and can be fixed to the steel structure, and the opposite end of the fixed part has a joint end, and the joint end has a Internally threaded holes are available for jointing; one end of the extension part has an extension end, and the extension end is an extension steel bar. With respect to the vertical extension of the steel structure, the steel structure is arranged in the continuous wall body.

To sum up, the horizontal steel bar lapping device for the underground diaphragm wall of this creation does not need to bend the extended steel bar multiple times as in the traditional way, which affects the strength of the steel bar. In other words, it can maintain the strength of the extended steel bar and make the overall structural strength stable. , with internal and external thread joints, the joint method is fast, convenient and stable, and has the beneficial effect of greatly reducing the difficulty of construction and fast construction.

Various embodiments are proposed below in conjunction with the drawings for detailed description. However, the embodiments are only used as examples for illustration, and do not limit the protection scope of this creation.

Please refer to Fig. 1 and Fig. 2 at the same time. Fig. 1 is a schematic diagram of the use state of this creation, and Fig. 2 is a three-dimensional schematic diagram of a disassembled state of this creation. A fixed part 10 and an extension part 20, the fixed part 10 is arranged on the steel bar structure 3, the material of the fixed part 10 can be, for example: steel material, but not limited to this; one end of the fixed part has a fixed end 102 can be fixed on On the steel bar structure 3, the fixed end 102 is a disk portion, and the disk portion of the fixed end 102 can be advantageously engaged and fixed on the steel bar structure 3. The opposite end of the fixed portion 10 has a joint end 104, and the joint end 104 has a An internally threaded hole is available for joining, and the reinforcement structure 3 can be, for example, a reinforcement cage, but not limited thereto; as shown in Figure 1, a plurality of underground continuous wall horizontal reinforcement laps 1 can be arranged on the reinforcement structure 3 as required And 1', the extension 20 can be extended relative to the vertical direction of the steel structure 3, but not limited thereto; please refer to Figure 2, one end of the extension 20 has an extension 202, and the extension 202 is an extension steel bar, depending on the demand Extending an appropriate length, the opposite end of the extension 20 has an external threaded end 204 corresponding to the internal threaded hole of the joint end 104, and the external threaded end 204 can be engaged and fixed in a screwed manner with the internal threaded hole of the joint end 104, because This creation is fixed by screwing, and the combination is firm and not loose.

Fig. 3 is a sectional view of the separated state of the present invention. As shown in the figure, viewed from the cross-sectional view, the extension part 20 has not been combined with the fixed part 10, and the fixed part 10 is engaged and fixed on the steel structure 3 by the disc-shaped fixed end 102, and the steel structure 3 is located on the continuous wall. In the body 5, the joint end 104 of the fixed part is an internally threaded hole, corresponding to the externally threaded end 204 of the extension part 20; In the wall body 5, the extension part 20 has been combined with the fixed part 10, and the external threaded end 204 of the extension part 20 is engaged and fixed with the internal threaded hole of the joint end 104 in a threaded manner. Since it is fixed in a threaded manner, the combination Stable and not loose, the extension end 202 of the extension part 20 is an extension steel bar, which can be extended to an appropriate length according to actual needs.

The horizontal steel bar lapper for the underground diaphragm wall of this creation uses the fixed part and the extension part to be screwed together, and then extends the extended steel bar. It does not need to bend the extended steel bar multiple times, which can maintain the strength of the extended steel bar and make the overall structure The strength is stable, and it is joined by internal and external thread joints. The joint method is fast, convenient and stable, which has the beneficial effect of greatly reducing the difficulty of construction and achieving rapid construction.

The above-mentioned embodiments are only to illustrate the technical ideas and characteristics of this creation. Its purpose is to enable those who are familiar with this technology to understand the content of this creation and implement it accordingly. It should not limit the patent scope of this creation. That is to say, all equal changes or modifications made according to the spirit disclosed in this creation should still be covered by the patent scope of this creation.
