Description

Technical Field

[0001] The utility model relates to a fully prefabricated concrete building, in particular to a connecting structure between a precast gable wall panel and a precast roof slab. Background Art

[0002] A prefabricated concrete building refers to a concrete structure building designed and constructed by means of on-site assembly mainly with precast reinforced concrete components produced in factories. It is generally divided into two categories: fully prefabricated buildings, which are generally low-rise or multi-story buildings with relatively low seismic fortification requirements; and partially prefabricated buildings, in which the main components generally adopt precast components and are connected by cast-in-place concrete on site to form an assembled monolithic structure building.

[0003] At present, fully prefabricated concrete buildings have been widely promoted, but the assembled connection between the precast gable wall panel and the precast roof slab has not been well solved. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a connecting structure between a precast gable wall panel and a precast roof slab with reliable connection.

A plurality of concave portions are arranged along the height direction on the ridge of the precast gable wall panel, and a first connecting box is installed in the concave portion. The first connecting box comprises an inclined plate flush with the ridge of the precast gable wall panel and a bottom plate horizontally installed. A plurality of first connecting pieces are embedded in the lower surface of the precast roof slab. The precast roof slab is placed on the ridge of the precast gable wall panel, and the first connecting pieces are fixedly connected with the inclined plate into a whole.

[0007] In the utility model, a plurality of concave portions are arranged along the height direction on the ridge of the precast gable wall panel, and a first connecting box is installed in the concave portion. The first connecting box comprises an inclined plate flush with the ridge of the precast gable wall panel and a bottom plate horizontally installed. A plurality of first connecting pieces are embedded in the lower surface of the precast roof slab. The first connecting pieces are fixedly connected with the inclined plate of the first connecting box into a whole. In this way, when the precast roof slab is placed on the precast gable wall panel under the action of gravity, the precast roof slab will not slide down or fall off, so that the reliable connection between the precast gable wall panel and the precast roof slab is realized.

[0008] Preferably, the first connecting piece is a connecting sleeve or a connecting bolt.

[0009] Preferably, the connecting sleeve or the connecting bolt is perpendicular to the precast roof slab.

[0010] Preferably, second connectors are respectively embedded in the concave parts of the precast gable wall panels, and the second connectors are fixedly connected to the bottom plate of the first connection box as a whole.

[0011] Preferably, the second connector is a connecting sleeve or a connecting bolt.

[0012] Preferably, the connecting sleeve or the connecting bolt is arranged vertically.

[0013] Preferably, the first connection box is a right-angled triangle-shaped connection box.

[0014] Preferably, the precast gable wall panel and the precast wall panel are connected through a second connection box.

[0015] Preferably, the second connection box is embedded in the precast gable wall panel, and second connectors are embedded in the precast wall panel. The second connectors are fixedly connected to the second connection box as a whole.

[0016] Preferably, a mortar layer is respectively arranged between the precast gable wall panel and the floor slab, and between the floor slab and the precast wall panel.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The present utility model is mainly applied to the connection of precast gable wall panels, precast roof slabs and precast wall panels of pitched roof-shaped buildings. Moreover, the precast components of the connection structure of the present utility model do not have protruding connecting steel bars before installation, so that it can meet the requirements of container transportation of precast components.

[0019] 2. The structure of the present utility model is stable and the connection is reliable.

[0020] 3. The present utility model reduces the construction difficulty of the vertical connection of precast gable wall panels, shortens the construction period, enhances the structural integrity, well protects the surrounding environment, and can achieve green construction.
