Embodiment 1

[0045] The invention provides a connection node between the truss body and the concrete structure, such as Figure 2-5 As shown, the concrete structure 1 includes a column 11 and two beams 12 located on one side of the column 11. I-shaped steel 13 is pre-embedded in the two beams 12, and the truss body 2 is a steel truss body, that is to say, the truss body 12 is formed by connecting section steels, specifically, the section steels include one or more of I-shaped steels, T-shaped steels, and H-shaped steels.

[0046] The connection node 3 includes a first cross beam 31 , a second cross beam 32 , a first shaped steel 33 and a second shaped steel 34 .

[0047] The first beam 31 and the second beam 32 are respectively extended from the two beams 12 in the concrete structure 1 .

[0048] It should be noted that the first crossbeam 31 and the second crossbeam 32 are integrally formed with the crossbeam 12 respectively, that is, the shaped steel in the first crossbeam 31 and the se...

Embodiment 2

[0070] The invention also discloses a truss, which includes a truss body and a connection node 3 between the truss body 2 and the concrete structure in Embodiment 1.

[0071] The truss body 2 is an arc structure, such as Figure 6-8 shown.

[0072] The truss body 2 includes an upper chord 21 , a lower chord 22 and at least two webs 23 , the upper chord 21 and the lower chord 22 are arc-shaped, and the upper chord 21 and the lower chord 22 are parallel. The upper chord 21 is used for bearing pressure, and the lower chord 22 is used for bearing tension.

[0073] The web 23 is welded between the upper chord 21 and the lower chord 22 . The web 23 mainly plays a supporting role, thereby reducing the width of the upper chord 21 and the lower chord 22 to ensure the rigidity of the overall structure.

[0074] Upper chord 21, lower chord 22 and web 23 are section steel.

[0075] The number of upper chords 21 is two, and the webs 23 are welded between the two upper chords 21 .

Embodiment 3

[0078] A method for connecting a truss body to a concrete structure, using the connection node between the truss body and the concrete structure in Embodiment 1, the method comprising the following steps:

[0079] Step 1: Pass the two beams 12 of the concrete structure 1 through the column 11, extend and pour to one end of the truss body 2, and no concrete is poured at the extended end, exposing the I-shaped steel;

[0080] Step 2: welding the two ends of the vertically placed first section steel 33 to the I-shaped steel at the two extension ends respectively;

[0081] Step 3: The I-shaped steel at the first end 35 is welded to the top of the truss body 2;

[0082] Step 4: The I-shaped steel plate at the second end 36 is repaired and welded with a steel plate to form an L-shaped groove. One end of the second steel 34 is welded to the L-shaped groove, and the other end is welded to the bottom of the truss body 2 .

[0083] Using the above connection method, the installation is...

Abstract

The invention discloses a connection node between a truss body and a concrete structure, a truss and a method. The connection node includes a first crossbeam, a second crossbeam, a first section steel and a second section steel; The two beams are extended, and the I-shaped steel is exposed at the extended end. The end of the first beam is the first end, and the end of the second beam is the second end; the I-shaped steel at the first end is welded to the top of the truss body; the second The I-shaped steel at the end is welded with steel plates to form an L-shaped slot. One end of the second-shaped steel is welded to the L-shaped slot, and the other end is welded to the bottom of the truss body; one end of the first beam and the second beam are placed vertically. The first type steel is welded; the first type steel is welded with the lower end of the truss body. The connection node of the invention is convenient to install, has good construction measures, is safe and reliable, and has low cost.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a connection node between a truss body and a concrete structure, a truss and a method. Background technique [0002] At present, for large-scale public spaces in public buildings, truss structures are required to meet the building functions. The traditional method is to connect the truss structures directly to the concrete components, that is, by installing two outstretched corbels horizontally on the concrete columns. The corbel and truss are fixedly connected by bolts, such as figure 1 shown. [0003] However, the direct connection between the truss structure and the concrete structure mainly has the following defects and deficiencies: [0004] 1) The truss members occupy the building plane function; [0005] 2) The joints between trusses and concrete members are not suitable to meet the design requirements, the cross-section is too large, and the cost is high;...
