Fabricated sash beam structure

Abstract

The utility model discloses an assembly type sash beam structure, which relates to the technical field of sash beams and comprises a prefabricated sash beam body and a dense-mesh steel fence cage, and reserved steel bar heads are preset at two ends of the prefabricated sash beam body; and the reserved steel bar head can be anchored into the dense-mesh steel fence cage. When a traditional cast-in-place frame beam is used for pouring a frame beam support slope in a cast-in-place mode, the time efficiency of a construction period is long, the early support strength is low, and a slope structure is easy to damage when a soil body slope with a higher structure is subjected to construction disturbance. The assembly type sash beam structure is low in labor cost, short in construction period and good in forming quality in the installation process.

Description

Technical Field

[0001] The utility model relates to the technical field of lattice beams, in particular to an assembled lattice beam structure. Background Art

[0002] Frame beams are also called frame beams, including anchor frame beams and anchor cable frame beams. The frame beams are composed of horizontal beams and vertical beams in a grid shape. They are used in mountain highway construction and installed on landslide bodies such as road cut slopes to enhance the slope's anti-scouring ability, improve the stability of the landslide body, and constrain the deformation of the slope surface. When constructing frame beams, it is necessary to go through foundation excavation, frame beam steel bar production and installation, frame beam template installation, frame beam concrete pouring, maintenance, and demolding. It can also be prefabricated in the factory in advance, and then the prefabricated frame beams are transported to the construction site for assembly. When the frame beams are cast in place to support the slope, the construction period is often long and the early support strength is low. For the high structural soil slopes, the slope structure is easily damaged by construction disturbance. When it is not supported in a timely and effective manner, it is easy to cause natural disasters such as slope instability, endangering human life and property safety; moreover, cast-in-place frame beams require a large amount of concrete to be transported, and the construction road requirements are high.

[0003] When assembling prefabricated frame beams, the slots on one side of one set of frame beams are generally connected to the blocks on one side of another set of frame beams, and then bolts are used to lock them. This installation method is more cumbersome and requires the use of multiple sets of bolts, which slows down the construction speed. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a prefabricated assembled frame beam structure which is simple and quick to assemble and has comprehensive functions.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An assembled frame beam structure comprises a prefabricated frame beam body and a dense mesh steel cage. Both ends of the prefabricated frame beam body are preset with reserved steel bar heads; the reserved steel bar heads can be anchored in the dense mesh steel cage.

[0007] Furthermore, the dense mesh steel cage is a wet joint dense mesh steel cage.

[0008] Furthermore, the close-mesh steel fence cage includes a steel bar skeleton and a close-mesh steel fence net wrapped around the steel bar skeleton.

[0009] Furthermore, the steel skeleton is formed by tying steel bars.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] When traditional cast-in-place frame beams are cast in-place to support slopes, the construction period is often long and the early support strength is low. For high structural soil slopes, the slope structure is easily damaged when disturbed by construction. The assembled frame beam structure provided by the utility model has low labor costs, short construction period and good molding quality during the installation process.

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0019] like Figures 1 to 4 As shown, this embodiment provides an assembled lattice beam structure, including a prefabricated lattice beam body 1 and a dense mesh steel cage 2. During the prefabrication process of the prefabricated lattice beam body 1, reserved steel bar heads 101 with sufficient anchoring length are reserved in advance at both ends thereof; the dense mesh steel cage 2 is a wet joint dense mesh steel cage, including a steel bar skeleton 201 and a dense mesh steel mesh 202, the steel bar skeleton 201 is composed of steel bars tied together, and the dense mesh steel mesh 202 is wrapped on the outside of the steel bar skeleton 201 to form a dense mesh steel cage 2 for pouring concrete 3, so that the steel cage can achieve the effect of directly pouring concrete 3.

[0020] During the actual operation, the dense mesh steel cage 2 is first positioned and installed at the specified position on the slope, and then the reserved steel bar heads 101 at both ends of the prefabricated lattice beam body 1 are anchored into the installed dense mesh steel cage 2 to ensure the accuracy and straightness of the installation position of the prefabricated lattice beam; the reserved steel bar heads 101 anchored in the dense mesh steel cage 2 are then tied and overlapped, which can effectively improve the connection strength and bending and shear resistance of the lattice beam structure, and finally concrete 3 is poured in the dense mesh steel cage 2 of the installed lattice beam support system.

[0021] When traditional cast-in-place frame beams are cast in-place to support slopes, the construction period is often long and the early support strength is low. For high structural soil slopes, the slope structure is easily damaged when disturbed by construction. The assembled frame beam structure provided by the utility model has low labor costs, short construction period and good molding quality during the installation process.

[0022] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
