[0001] The utility model relates to the technical field of anti-shearing of waist beams of underground integrated pipe corridors, and more specifically, to a waist beam anti-shearing structure. Background Art
[0002] With the rapid development of society, people's requirements for urban environmental quality are getting higher and higher. As underground pipelines such as water supply, drainage, electricity, telecommunications, and gas become increasingly complex, how to scientifically, safely, and efficiently manage and maintain existing or to-be-built pipe culvert projects has become one of the hot spots and difficulties in current municipal engineering research.
[0003] The emergence of the underground comprehensive pipeline corridor system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and inspection of the above-mentioned municipal facilities. At the same time, it effectively utilizes the space under the road and saves urban land. It plays an extremely important role in meeting the basic needs of the people's livelihood and improving the comprehensive carrying capacity of the city.
[0004] During the construction of underground comprehensive pipeline corridors, most of them are in an enclosed state, and diagonal braces are set inside to improve their overall strength. However, some underground comprehensive pipeline corridors are in a non-enclosed state, that is, the ends of some underground comprehensive pipeline corridors are in a free state, and diagonal braces are set inside. This causes the waist beam of the underground comprehensive pipeline corridor to be under stress at one end, which affects its strength and stability.
[0005] Therefore, based on the above-mentioned problem, the above-mentioned structure is urgently needed to improve the stability and strength of the waist beam. Utility Model Content
[0006] The utility model provides a waist beam shear-resistant structure to solve the problem that the stability and strength of the existing underground integrated pipe gallery are weakened due to the force of the inner diagonal brace.
[0007] According to one aspect of the present invention, a waist beam shear resistance structure is provided, wherein one end of the waist beam is in a free state, and the inner side surface of the waist beam is provided with an inclined reinforced concrete support, and the outer side of the waist beam is provided with cast-in-place piles, the shear resistance structure is multiple and is arranged at intervals on the outer side surface of the waist beam corresponding to the reinforced concrete support. The shear resistance structure includes an L-shaped beam frame and an arc-shaped diagonal brace, and adjustment holes are provided at both ends of the beam frame. The two ends of the diagonal brace are detachably connected to the adjustment holes, and the arc shape of the diagonal brace is adapted to the cast-in-place piles.
[0008] Preferably, based on the above solution, the beam frame includes a crossbeam and a longitudinal beam, and the crossbeam is fixed to the longitudinal beam by welding.
[0009] Preferably, based on the above solution, the cross beam and the longitudinal beam are channel steels.
[0010] Preferably, based on the above solution, a steel plate is pre-embedded on the waist beam, and the beam frame is welded to the steel plate.
[0011] Preferably, based on the above solution, an anti-slip pad is provided on the inner side of the diagonal brace.
[0012] The utility model provides a waist beam shear resistance structure, which sets a shear resistance structure on the opposite side of the waist beam and the reinforced concrete support, and utilizes the arc-shaped diagonal brace on the shear resistance structure to contact the outer edge surface of the cast-in-place pile, so as to provide the waist beam with a supporting force opposite to the reinforced concrete support to ensure that the waist beam is balanced in force. At the same time, the arc-shaped diagonal brace is adopted to make the force more balanced.
[0013] The two ends of the diagonal brace of the utility model are adjustably connected to the two ends of the beam frame respectively. Therefore, it can be adjusted according to the position and size of the cast-in-place pile to ensure the fit between the cast-in-place pile and the inner side surface of the arc support to ensure its force effect.

The cross beam 9 and the longitudinal beam 10 are channel steels. In order to facilitate installation, the present invention also pre-embeds a steel plate 11 on the waist beam 1. The beam frame 5 is welded to the steel plate 11, and the steel plate 11 is reinforced with anchor bars 20 to strengthen the connection strength in the waist beam 1.
[0032] The inner side surface of the diagonal brace 6 of the present invention is provided with an anti-skid pad 12 to increase the friction force thereof and facilitate adjustment of the position between the cast-in-place pile 3 and the diagonal brace 6 .
[0033] The utility model provides a shear-resistant structure 4 of a waist beam 1, which is provided with the shear-resistant structure 4 on the opposite side of the waist beam 1 and the reinforced concrete support 2, and utilizes the arc-shaped diagonal braces 6 8 on the shear-resistant structure 4 to contact the outer edge surface of the cast-in-place pile 3, thereby providing the waist beam 1 with a supporting force opposite to the reinforced concrete support 2 to ensure that the force is balanced. At the same time, the arc-shaped diagonal braces 6 8 are adopted to make the force more balanced.
[0034] The two ends of the diagonal brace 6 of the present invention are adjustably connected to the two ends of the beam frame 5 respectively. Therefore, it can be adjusted according to the position and size of the bored pile 3 to ensure the fit between the bored pile 3 and the inner side surface of the arc support 8 to ensure its force effect.
