Embodiment 1

[0039] Embodiment 1: as figure 2 As shown, the anti-frost heaving structure of the side beam of this building includes the beam bottom insulation layer 1, cushion layer 2, filling layer 3 between the bottom of the side beam 0 and the bottom of the excavation pit, the beam outer insulation layer 4 on the outside of the side beam 0, asphalt isolation Layer 5, wherein, the beam bottom insulation layer 1 is arranged on the bottom surface of the side beam 0, the cushion layer 2 is arranged on the bottom surface of the excavation pit, and the filling layer 3 is filled in the beam bottom insulation layer 1 and the cushion layer 2; the asphalt insulation layer 5 is arranged on the outside of the overall structure formed by the side beam 0, the beam bottom insulation layer 1, and the filling layer 3, and the beam outer insulation layer 4 is arranged on the outside of the asphalt insulation layer 5; the beam bottom Both the insulation layer 1 and the beam outer insulation layer 4 are e...

Embodiment 2

[0041] Embodiment 2: as image 3 As shown, the inside of the side beam 0 of the side beam anti-frost heave structure of this building is provided with a beam inner insulation layer 9, an asphalt isolation layer 5 and a reinforcement pier 31, and the reinforcement pier 31 is integrated with the bottom and the filling layer 3. Adding the insulation board inside the beam can eliminate the horizontal and tangential frost heaving force inside the foundation beam, and strengthen the pier and bottom and the filling layer to improve the integrity and stability of the beam bottom structure. The remaining structures and components are as described in Embodiment 1 and will not be described again.

Embodiment approach 1

[0042] Implementation mode 1: if Figure 4 As shown, for the anti-frost heave structure of the building edge beam in embodiment 1, its concrete construction method comprises the following steps,

[0043] S1 earthwork excavation: Excavate the outer earthwork of the side beam to be treated until the lower surface of the side beam is exposed, and continue to excavate 100cm downward, and excavate the inside and bottom of the excavation pit to form a vertical surface on the inside and a plane on the bottom. excavation pit;

[0044] S2 Cushion pouring: set concrete formwork on the bottom surface of the excavation pit, pump commercial concrete to the formwork to form a cushion, and mechanically vibrate for compaction;

[0045] S3 Beam Bottom Insulation Layer Laying and Protective Layer: After the beam bottom is treated, the side beams are positioned and laid out, and the beam bottom insulation board is laid on the beam bottom. The bottom insulation board is combined with a polymer ...

Abstract

The invention relates to a building boundary beam frost heaving prevention structure which comprises a beam bottom heat preservation layer, a cushion layer, a filling layer, a beam outer heat preservation layer on the outer side of a boundary beam and an asphalt isolation layer, the beam bottom heat preservation layer is arranged on the bottom face of the boundary beam, the cushion layer is arranged on the bottom face of an excavation pit, and the space between the beam bottom heat preservation layer and the cushion layer is filled with the filling layer; the asphalt isolation layer is arranged on the outer side of an integral structure formed by the edge beam, the beam bottom heat preservation layer and the filling layer, and the beam outer heat preservation layer is arranged on the outer side of the asphalt isolation layer; the beam bottom heat preservation layer and the beam outer heat preservation layer are both polystyrene foam extrusion molding heat preservation plates. The invention further relates to a construction method of the building boundary beam frost heaving prevention structure. According to the structure, the heat preservation layers are arranged on the beam bottom and the outer side of the beam, the effect of foundation soil frost heaving force on the foundation boundary beam is reduced or avoided, and on the basis that the construction efficiency and quality are improved, the construction cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of construction techniques, in particular to a construction edge beam anti-frost heaving structure and a construction method thereof. Background technique [0002] Frost heaving force is a kind of internal stress formed when the soil is frozen and frost heaves, the water inside the soil turns into ice to make its volume expand, and the relative displacement of soil particles occurs. [0003] Since the foundation or foundation beam of the building is located in the frozen soil layer, the foundation or foundation beam restricts the frost heave deformation of the foundation soil, and the frost heaving force generated when the foundation soil freezes will act on the foundation or foundation beam in the form of load. In turn, it causes the displacement and deformation of the foundation. When the displacement and deformation continue to accumulate and reach a certain level, it will directly affect the stability and safety o...
