TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a support structure for large pipe joint pre -buried construction. BACKGROUND

[0002] In underground building construction, due to the complexity and diversity of the pipeline system, pipe joints are usually pre-buried on the concrete wall to facilitate easy connection of adjacent pipelines on both sides of the wall during subsequent construction, ensuring smooth pipeline systems.

[0003] In the prior art, pipe joints in underground buildings are pre-buried and installed by lifting equipment to the steel reinforcement framework in the concrete shear wall, and then connected to the steel reinforcement framework of the wall in a suspended state to form support for the pipe joints. Alternatively, the pipe joints are lifted to the wall formwork support using lifting equipment when the wall formwork is set up, and the pipe joints are supported by the wall formwork support. However, the above construction methods have the following defects: (1) During concrete pouring of the wall, the steel reinforcement framework or wall formwork support will be disturbed by the load and deformed, which will cause displacement of the pipe joints and potential installation quality problems; (2) When large pipe joints are pre-buried and installed, the steel reinforcement framework or wall formwork support in the wall cannot withstand the gravity load of the pipe joints, and forced fixation will not only cause quality problems, but also pose a significant safety hazard.

[0004] Therefore, it is necessary to improve the existing large pipe joint pre-buried construction method to effectively solve the problems existing in the prior art. INVENTION CONTENTS

[0005] Therefore, the purpose of the utility model is to provide a support structure for large pipe joint pre-buried construction, which realizes independent and reliable fixation of large pipe joints by setting a lower support assembly below the large pipe joint pre-buried position and an upper support assembly in the inner circular hole of the large pipe joint, avoiding the influence of concrete pouring or the influence of its own load, thereby improving the installation quality of large pipe joints and avoiding safety hazards.

[0006] The utility model provides a support structure for large pipe joint pre-buried construction, which comprises an upper support assembly and a lower support assembly, the lower support assembly is arranged below the large pipe joint pre-buried position and is used for supporting the bottom of the flange plate of the large pipe joint, and the upper support assembly is arranged in the inner circular hole of the large pipe joint and is used for supporting the top of the inner circular hole.

[0007] Further, the lower support assembly comprises lower support pieces symmetrically arranged on the left and right sides of the central axis of the large pipe joint, and the lower support pieces comprise vertical support columns pre-buried in the concrete beam plate and horizontal support beams arranged at the top of the vertical support columns.

[0008] Further, the upper support assembly comprises trapezoidal support frames symmetrically arranged on the front and back of the large pipe joint in the axial direction, and a connecting cross beam for supporting the top of the inner hole of the large pipe joint is arranged between the two trapezoidal support frames.

[0009] Further, the connecting cross beam is two and symmetrically arranged on the trapezoidal support frames on the left and right sides of the central axis of the large pipe joint.

[0010] Further, the top of the trapezoidal support frame is provided with a limiting piece for limiting the axial position of the large pipe joint.

[0011] Further, the bottom of the trapezoidal support frame is provided with a support embedded part for fixing the trapezoidal support frame on the concrete beam plate.

[0012] The support structure for large pipe joint pre-embedded construction has the advantages that: the lower support assembly arranged below the pre-embedded position of the large pipe joint realizes the preliminary support positioning of the large pipe joint hoisted to the pre-embedded position, and the upper support assembly arranged in the inner hole of the large pipe joint realizes the further support bearing and movement limiting of the large pipe joint; the support structure realizes the independent and reliable fixing of the large pipe joint, can effectively ensure the installation position accuracy of the large pipe joint, greatly reduces the safety hidden trouble in the construction process, and the upper support assembly can be recycled after the construction is completed, thereby reducing the material loss.
