Embodiment 1

[0039] Such as Figure 1-4 As shown, this embodiment discloses a construction joint setting structure, the construction joint setting structure is set at the construction joint of the concrete structure, and the construction joint of the concrete structure can be a concrete floor, a floor horizontal construction joint and a shear wall Vertical construction joints; specifically, the construction joint leaving structure includes a first ladder-shaped fixing frame 2, a second ladder-shaped fixing frame 4 and a water-proof steel plate 3; the first ladder-shaped fixing frame 2 and the second ladder-shaped fixing frame 4 are respectively fixed on the upper and lower surfaces of the water-stop steel plate 3 and correspond up and down, and the first ladder-shaped fixing frame 2 and the second ladder-shaped fixing frame 4 are perpendicular to the water-stop steel plate 3; the first ladder-shaped fixing frame 2 and the second ladder-shaped fixing frame 2 Ladder-shaped fixing frames 4 ar...

Embodiment 2

[0046] Such as Figure 5 As shown, the present invention also discloses a construction method for leaving a structure with construction joints, specifically, the construction method includes the following steps:

[0047] Step S1, providing a first ladder-shaped fixing frame and a second ladder-shaped fixing frame, and laying expanded metal on both the first ladder-shaped fixing frame and the second ladder-shaped fixing frame.

[0048] Specifically, the above step S1 is specifically:

[0049] Step S11 , providing 2 sets of ladder-shaped fixing frame materials, such as steel bars with a diameter of Φ10, and each set of ladder-shaped fixing frame materials includes 2 main keels and several secondary keels.

[0050]Step S12, processing the ladder-shaped fixing frame, the distance d of the two main keels of the first ladder-shaped fixing frame is determined and set according to the distance from the steel bar at the bottom of the slab to the water-stop steel plate, and the distanc...

Abstract

The invention relates to the technical field of building construction, in particular to a construction joint setting-up structure and a construction method thereof. By directly arranging scalariform fixing frames between plate bottom steel bars and water-stop steel bars at construction joints and between water-stop steel plates and plate face steel bars, fixedly covering the whole scalariform fixing frames with steel plate nets and adopting customized aluminum alloy square tube members on concrete upper surface to serve as suspended frameworks, concrete at the construction joints is formed regular, smooth and straight, and concrete leaked from a gap formed at a closing position is easy to clear. In addition, the construction operation is simple, time and labor are saved, the quality requirement of construction joint concrete casting is ensured, the construction joint treating difficulty is greatly reduced, and the constructing hidden danger of construction joint water leakge is indirectly avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a construction joint leaving structure. Background technique [0002] At present, there are mainly two schemes for retaining construction joints in the concrete construction of the structural bottom plate, floor slab horizontal construction joints and shear wall vertical construction joints. One is to use double-layer steel wire mesh to bind and fix it on the column reinforcement to cut off the interface of the construction joint. The binding strength of the steel wire and the column reinforcement in this treatment plan is not enough. During the concrete construction, the interface shape is "V"-shaped, and the indwelling surface is rough, uneven, and irregular, which is not conducive to the treatment of the construction joints of the secondary construction of the concrete, and increases the construction cost. The difficulty of dealing with ...
