Problems solved by technology

The reinforcement form of the traditional cast-in-place reinforced concrete parapet adopts the form of double-layer steel mesh, such as figure 1 As shown, the steel bars are thin and numerous. If this connection method is directly converted to the prefabricated parapet wall, double rows of very dense steel bars should protrude from the top of the roof beam, and at the same time, thin and dense double rows of sleeves should be pre-embedded in the prefabricated parapet wall. 7. On-site hoisting of the prefabricated parapet wall It is difficult to insert the steel bars protruding from the top of the roof beam into the inner sleeve of the prefabricated parapet wall at the same time, and the workload of grouting in the later stage is very large, so the hoisting is difficult, the construction period is long, and materials are wasted Many, can not fully reflect the advantages of industrialization

Embodiment Construction

[0016] On the premise of ensuring the strength and service requirements of the parapet wall under the corresponding load conditions, the simplified steel connection method can achieve better economic benefits. In the present invention, the double-row steel bar sleeve connection mode in the traditional connection is changed to a single-row steel bar connection, and a single-row galvanized corrugated steel pipe 8 with an inner diameter 40mm larger than the steel bar diameter is pre-embedded in the middle of the prefabricated parapet 1, and the galvanized corrugated steel pipe The upper part shall be welded and closed with thin iron sheets, and the prefabricated composite beams 2 of the roof are pre-embedded steel bars with large spacing and large diameter. When calculating the pre-embedded steel bars, the thickness h of the parapet wall shall be calculated. 0 The distance from the center of the galvanized bellows of the parapet to the edge of the parapet in the bending direction ...

Abstract

The invention discloses a connection structure of steel bars of a prefabricated parapet. Single row galvanized corrugated steel pipes are embedded into the center in the prefabricated parapet; the top of the galvanized corrugated steel pipe is closed; lapped beam embedded single row steel bars are prefabricated on a roof; the single row steel bars extend out of the prefabricated lapped beam of the roof and are arranged in the single row galvanized corrugated steel pipes; an upper part slurry outlet and a lower part grouting hole are also formed in the single row galvanized corrugated steel pipes. The prefabricated parapet with single row galvanized corrugated steel pipes being embedded is easily butted with the steel bars extending out of the roof lapped beam during field hoisting, the hoisting is quickened, and the construction period is shortened, and as the single row galvanized corrugated steel pipes are adopted, the field grouting efficiency is improved.

Description

technical field [0001] The invention relates to a prefabricated parapet wall reinforcement connection structure, which belongs to building industrialization and prefabrication assembly technology. Background technique [0002] Prefabricated parapet is a commonly used component in prefabricated buildings. Since the parapet is a decorative component and does not participate in the stress of the main structure, the connection method of the prefabricated parapet can be appropriately simplified compared with structural components; It needs to bear large wind load, horizontal seismic load on the top of the house and external horizontal thrust, and its connection should also meet the requirements of strength and use under the additional load. [0003] The parapet is a non-main structural component of the roof. If the prefabrication of the parapet can be realized, it is very important to realize the full prefabrication of structural components. The reinforcement form of the traditi...
