Description

Temporary access bridge for construction

technical field

The invention relates to a building passing device, in particular to a temporary building passing bridge.

Background technique

When building bridges on some rivers with small widths, sometimes due to the needs of temporary traffic, a temporary bridge for traffic must be erected near the bridge under construction. The bridge can also be used for auxiliary bridge construction. The usual way is to erect A simple bridge made of wood or bamboo will be dismantled after the formal bridge is built, but at the same time, the safety hazards of such a bridge are relatively large, especially in rivers where the river water often fluctuates. .

Contents of the invention

The present invention aims at the above problems and proposes a temporary access bridge for construction. The temporary access bridge is simple to install, firm to use and greatly improved in safety.

In order to achieve the above-mentioned technical purpose, the present invention adopts a kind of temporary access bridge for construction, including the first bridge body, the second bridge body and the third bridge body which can be connected with each other by bolts, the first, second and third bridge bodies The upper end of the bridge body is provided with a passage plate, the bottoms of the first and third bridge bodies are provided with screw nut drill devices, and the left end of the first bridge body and the right end of the third bridge body are equipped with hand-operated screw nuts. Rod nut pulling device; the screw nut drill device includes a first screw nut pair with a drill bit at the bottom, and the upper end of the first screw nut pair is provided with an electric motor that can make the first screw nut pair travel and expand. Motor device; the hand-operated screw nut pulling device includes a groove, and a horizontal plate with a hand-operated screw nut pair at the bottom is arranged in the groove, and the movable end of the horizontal plate is fixed with a bolt hole.

The present invention greatly simplifies the installation mode of the bridge and the connection mode with the river bottom through splicing and horizontal and vertical screw nut systems, and is safe and firm.

Description of drawings

What Fig. 1 shows is the schematic diagram of appearance structure of the present invention;

Among them, 1. The first bridge body; 2. The second bridge body; 3. The third bridge body; 4. The passage plate; 5. The drill bit; 6. The first screw nut pair; Groove; 9, hand screw nut pair; 10, horizontal plate; 11, bolt fixing hole.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As can be seen from Fig. 1, a temporary access bridge for construction includes a first bridge body 1, a second bridge body 2 and a third bridge body 3 which can be connected to each other by bolts. , the upper end of the third bridge body 3 is provided with a passage plate 4, the bottom of the first bridge body 1 and the third bridge body 3 is provided with a screw nut drill device, and at the left end of the first bridge body 1 and the third bridge body 3 The right end is equipped with a hand-operated screw nut pulling device;

In the present invention, the preferred screw nut drill device includes a first screw nut pair 6 with a drill bit 5 at the bottom, and an upper end of the first screw nut pair 6 is provided to enable the first screw nut pair 6 to advance. Telescopic electric motor unit 7 .

In the present invention, the preferred hand-operated screw nut pulling device includes a groove 8, and a horizontal plate 10 with a hand-operated screw nut pair 9 at the bottom is provided in the groove 8. The movable end is provided with a bolt fixing hole 11 .

The present invention is specifically used in this way: first, the first bridge body 1, the second bridge body 2 and the third bridge body 3 are connected by bolts, and the second bridge body 2 can be one or more in actual use. wide, then a plurality of second bridge bodies 2 can be used for connection; if the bridge deck is relatively narrow, a small amount of second bridge bodies can be used for connection; At the same time, bolts are used to fix the horizontal plate 10 and the two ends of the river bank through the bolt fixing holes 11, and finally the electric motor device 7 is started, and the first screw nut pair 6 and the drill bit 5 at the bottom are deeply inserted into the river bottom to play a role of fixing. In this way, the erection of the temporary access bridge is completed.
