Embodiment 1

[0046] figure 1 A cross-sectional view of the anti-misalignment I-beam provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the locking slot 2 includes a first locking slot 201 and a second locking slot 202 . When the profile body 1 is cut transversely, the first locking groove 201 is located on the upper surface of the left end of the upper wing 101 , and the second locking groove 202 is located on the lower surface of the left end of the lower wing 102 . In this embodiment, the first slot 201 and the second slot 202 with different positions, when a plurality of anti-slip I-beams are spliced ​​in parallel, any anti-slip I-beam can prevent adjacent anti-slip I-beams The beam moves up and down. Since the first slot 201 and the second slot 202 are arranged on the same side of the I-beam, the I-beam presents a horizontally symmetrical structure, and the center of gravity is relatively stable for easy transportation.

Embodiment 2

[0048] figure 2 A cross-sectional view of the anti-misalignment I-beam provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the locking slot 2 includes a first locking slot 201 and a second locking slot 202 . When the profile body 1 is cut transversely, the first locking groove 201 is located on the upper surface of the left end of the upper wing 101 , and the second locking groove 202 is located on the lower surface of the right end of the lower wing 102 . In this embodiment, similarly, the first card slot 201 and the second card slot 202 with different positions, when multiple anti-stagger I-beams are spliced ​​in parallel, any one anti-stagger I-beam can prevent adjacent anti-stagger I-beams Stagger the I-beam up and down. However, since the first clamping slot 201 and the second clamping slot 202 are arranged on different sides of the I-beam, a single I-beam is more evenly subjected to displacement force.

Embodiment 3

[0050] image 3 A sectional view of the anti-misalignment I-beam provided by Embodiment 3 of the present invention. Such as image 3 As shown, the locking slot 2 includes a first locking slot 201 and a second locking slot 202 . When the profile body 1 is cut transversely, the first locking groove 201 is located on the upper surface of the left end of the upper wing 101 , and the second locking groove 202 is located on the upper surface of the right end of the upper wing 101 . In this embodiment, similarly, the first card slot 201 and the second card slot 202 with different positions, when multiple anti-stagger I-beams are spliced ​​in parallel, any one anti-stagger I-beam can prevent adjacent anti-stagger I-beams Stagger the I-beam up and down. Since the first draw-in slot 201 and the second draw-in slot 202 are both arranged on the upper wing 101 of the I-beam, the structure of the lower wing 102 remains flat, which is convenient for transportation and storage.

Abstract

The invention provides an anti-shift transverse H-shaped beam and a self-prestress transverse H-shaped beam, relating to the technical field of tension and compression components. The anti-shift transverse H-shaped beam comprises profile bodies and clamping grooves, wherein the clamping grooves are formed in wing plates of the profile bodies; and the two adjacent profile bodies are spliced along the width direction, and the clamping grooves can be meshed with the abutted wing plates so as to form a transverse H-shaped beam combination with flat upper and lower surfaces. The self-prestress transverse H-shaped beam comprises the anti-shift transverse H-shaped beam, wherein upper wing plates and lower wing plates of the profile bodies are arc-shaped bent plates and are bent around an axis parallel with the width direction of the upper wing plates. According to the anti-shift transverse H-shaped beam, the problem that the adjacent profiles are easily shifted up and down due to imbalanced stressing between the profiles is effectively solved. The self-prestress transverse H-shaped beam has relatively strong bearing capacity, so that the limitation that a component has a small span is broken through. On this basis, the invention further provides a self-prestress span bridge.

Description

technical field [0001] The invention relates to the technical field of tension and compression components, in particular to a movement-preventing I-beam, a self-prestressing I-beam and a self-prestressing span bridge. Background technique [0002] The I-beam is a kind of steel profile, which is a long strip of steel with an I-shaped cross section. The mechanism of the I-beam includes the upper flange, the lower flange and the web in the middle. [0003] The structural technical parameters of the I-beam include height H, width B, flange thickness tf, web thickness tw, cross-sectional area A, moment of inertia I x , I y and the section modulus W x , W y Wait. [0004] In the traditional I-beam, the upper and lower flanges are straight structures. When multiple I-beams are combined to form a stressed component, it is easy to be dislocated up and down under different pressures, which affects the bearing capacity of the component. ability. Moreover, under high pressure, th...
