Problems solved by technology

[0004] During the construction of the pipe gallery, the roof of the pipe gallery is usually the last construction. When the roof of the pipe gallery is constructed, the steel mesh of the roof of the pipe gallery is usually bound between the two sets of side panels of the pipe gallery, and then the concrete is poured. The maintenance of the roof of the pipe gallery usually takes more than three days. The concrete strength of the roof of the pipe gallery after the pipe gallery usually needs to reach about 75% before the formwork can be removed; once the formwork is removed in advance, the concrete strength will be insufficient. Under the action of the roof's own weight and other vibration loads, the joint work ability of the concrete on the roof of the pipe gallery and the steel mesh will be poor, which will easily cause the steel mesh to slide in the concrete, thereby reducing the gripping force of the steel mesh, and eventually lead to the failure of the roof of the pipe gallery. decreased overall strength
[0005] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: it usually takes more than 3 days to wait for the concrete strength to reach 75%. A large number of construction personnel and equipment are waiting, which reduces the construction efficiency of the pipe gallery. Therefore, there is room for improvement

Embodiment 1

[0040] refer to figure 1 and figure 2 , a pipe gallery quick release system, including a frame erected on the top of two pipe gallery side panels 11, and also includes two sets of connecting plates 3 connected to the bottom side of the steel mesh 121 in the pipe gallery roof 12, two sets of connecting plates 3 Evenly distributed along the width direction of the pipe gallery roof 12, the upper surface of the connecting plate 3 is vertically fixedly connected with a lifting screw 31, and the end of the hanging screw 31 away from the connecting plate 3 protrudes from the upper surface of the pipe gallery roof 12, and the rack is located in the pipe gallery Above the top plate 12; the tops of the two sets of lifting screws 31 are provided with clamping parts, and the frame is provided with two sets of clamping parts corresponding to the two sets of clamping parts. then fixed. Utilize the frame to apply upward pulling force to the steel mesh 121 in the roof of the pipe gallery 1...

Embodiment 2

[0047] refer to image 3 and Figure 4 The difference between the second embodiment and the first embodiment is that the frame includes a fixed pipe 5 arranged horizontally, the two ends of the fixed pipe 5 are all plugged and slid with a slide bar 51, and the ends of the slide bar 51 away from the fixed pipe 5 are all vertical. A support rod 52 is fixedly connected downward, and a secondary abutment plate 521 is fixed around the outer wall of the bottom end of the support rod 52. The bottom side of the secondary abutment plate 521 is flush with the end surface of the bottom end of the support rod 52. The tops of the two sets of pipe gallery side plates 11 are in contact; the setting of the secondary abutment plate 521 is beneficial to increase the contact area between the bottom end of the support rod 52 and the pipe gallery side plates 11, and facilitates the dispersion of the frame load.

[0048] refer to image 3 and Figure 4 , the bottom ends of the support rods 52 ar...

Abstract

This application relates to the technical field of pipe gallery construction. Aiming at the defect that the formwork trolley in the traditional pipe gallery cannot be moved out of the pipe gallery in advance, resulting in low construction efficiency of the pipe gallery, a quick-release system for the pipe gallery is proposed, including The rack at the top of the side plate and several connecting plates pre-buried in the roof of the pipe gallery, the rack is located above the roof of the pipe gallery; the connecting plate is connected to the bottom side of the steel mesh of the roof of the pipe gallery, and the connecting plates are vertically provided with lifting screws. The end of the lifting screw that is far away from the connecting plate protrudes from the upper surface of the roof of the pipe gallery, and the frame is provided with a number of clamping parts. The space is clamped and fixed by the clamping piece and the clamping part. The application has the effect of improving the construction efficiency of the pipe gallery.

Description

technical field [0001] The application relates to the technical field of pipe gallery construction, in particular to a pipe gallery quick release system. Background technique [0002] With the continuous advancement of the urbanization process, the laying of various complex pipelines is also carried out. In order to prevent the confusion of pipeline laying and facilitate the repair of problematic pipelines in the later stage, it is often necessary to build underground tunnels for underground pipelines. Comprehensive pipe gallery, the pipe gallery is composed of the pipe gallery bottom plate 1, the pipe gallery side wall 11 and the pipe gallery roof 12 (refer to figure 1 ); the bottom plate 1 of the pipe gallery, the side plate 11 of the pipe gallery and the top plate 12 of the pipe gallery are all reinforced concrete structures. [0003] At present, the underground comprehensive pipe gallery is usually constructed by the formwork support construction method. The side formwo...
