Description

Mortise and tenon socket joint formula steel trestle crossbeam and steel-pipe pile connected node

Technical Field

The invention relates to a mortise and tenon socket type steel trestle crossbeam and steel pipe pile connecting node, and belongs to the field of bridge construction.

Background

Before the bridge is built, a steel trestle is often built on the side face of the bridge to be built in advance, the steel trestle needs to be built quickly, and the strength of the steel trestle can meet the bearing requirements of various large machines.

In traditional steel trestle, the steel-pipe pile is connected with the crossbeam and needs the opening on the steel-pipe pile, and need carry out welding operation with steel-pipe pile and crossbeam welding together, this kind of mode operating efficiency is low, and in case there is a steel-pipe pile and crossbeam welding insecure, just influences whole steel trestle's intensity easily, influences staff's safety.

Disclosure of Invention

The invention provides a mortise and tenon socket type steel trestle crossbeam and steel pipe pile connecting node, and aims to solve the problem that a steel pipe pile in a traditional steel trestle is installed with a crossbeam in a welding mode, so that the construction efficiency and the strength of the steel trestle are influenced.

The utility model provides a mortise and tenon socket joint formula steel trestle crossbeam and steel-pipe pile connected node, includes crossbeam and steel-pipe pile, the crossbeam side is equipped with extension portion, the steel-pipe pile upper end is equipped with one side open-ended mortise, the extension portion of crossbeam side insert tightly in the mortise, and with the mortise phase-match.

Further, the mortise faces the opening in the middle of the steel trestle.

Furthermore, the cross beam is I-shaped steel, and the lower end extension part of the I-shaped steel is inserted into the mortise.

Furthermore, the mortise is divided into an upper tenon sheet and a lower tenon sheet, the lower tenon sheet and the steel pipe pile are integrally manufactured, the upper tenon sheet is installed on the lower tenon sheet through screws, and the extending part of the cross beam is tightly pressed on the lower tenon sheet.

Further, the mortises and the steel pipe piles are integrally manufactured.

The mortise and tenon socket type steel trestle bridge beam and steel pipe pile connecting node has the following beneficial effects:

(1) the mortise and tenon structure is prefabricated in advance, so that the assembly type construction is adopted, and the speed is high;

(2) the damage to the steel pipe pile is small during installation;

(3) the mortise and tenon structure can be repeatedly recycled;

(4) this type of installation prevents the steel girder from tipping over.

Drawings

Fig. 1 is a schematic structural diagram of a mortise and tenon socket type steel trestle crossbeam and steel pipe pile connecting node.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a mortise and tenon socket joint formula steel trestle crossbeam and steel-pipe pile connected node, including crossbeam 1 and steel-pipe pile 2, crossbeam 1 side is equipped with extension portion 1a, steel-pipe pile 2 upper end is equipped with one side open-ended mortise 3, extension portion 1a of crossbeam 1 side insert tightly in mortise 3, and with mortise 3 phase-match.

In the preferred embodiment of this part, the mortise 3 is open towards the middle of the steel trestle.

In the preferred embodiment of this section, the cross beam 1 is an i-beam, and the lower end extension 1a of the i-beam is inserted into the mortise 3.

In this preferred embodiment, the mortise is divided into an upper tenon sheet 3a and a lower tenon sheet 3b, the lower tenon sheet 3b is integrally formed with the steel pipe pile 2, and the upper tenon sheet 3a is mounted on the lower tenon sheet 3b through screws and presses the extending part 1a of the cross beam 1 against the lower tenon sheet 3 b.

In the preferred embodiment of this section, the mortise 3 is integrally formed with the steel pipe pile 2.

Specifically, in the specific implementation process, the upper tenon sheet and the lower tenon sheet are preferably separated, the upper end of the steel pipe pile is opened before the upper tenon sheet is installed, concrete can be injected into the steel pipe pile to increase the weight and strength of the steel pipe pile, then the lateral extension part of the cross beam is placed on the lower tenon sheet, the upper tenon sheet is covered on the lower tenon sheet through bolts, and the cross beam is compressed to prevent the cross beam from moving.
