Abstract

The utility model discloses a steel bar connection structure for a prefabricated parapet wall. A single row galvanized corrugated steel pipe is embedded in the central position in the prefabricated parapet wall. The top of the single row galvanized corrugated steel pipe is sealed, a single row steel bar is embedded in a roof prefabricated composite beam, the single row steel bar extends out of the roof prefabricated composite beam to be arranged in the single row galvanized corrugated steel pipe, and an upper slurry output hole and a lower grouting hole are formed in the single row galvanized corrugated steel pipe. When hoisted in position on site, the prefabricated parapet wall with the embedded single row galvanized corrugated steel pipe is easily in butt joint with the steel bar extending out of the roof composite beam, hoisting speed is accelerated, and a construction period is shortened. Due to the fact that the single row galvanized corrugated steel pipe is adopted, on-site grouting efficiency is improved.

Description

Prefabricated parapet steel bar connecting structure
Technical field
The utility model relates to a kind of prefabricated parapet steel bar connecting structure, belongs to industrialization of construction industry and prefabrication and assembly construction technology.
Background technology
Prefabricated parapet is member commonly used in the prefabrication and assembly construction building, because parapet belongs to decoration element, does not participate in the stressed of agent structure, therefore the connected mode of prefabricated parapet can suitably be simplified than bearing carrier; Need again to bear larger wind load, top, house horizontal earthquake load and additional horizontal thrust but parapet is positioned at the top, house, it connects the requirement also should meet intensity and use under the imposed load effect.
Parapet is as the non-agent structure primary structure member of roofing, if realize the prefabricated of parapet, and complete prefabricated very important to the implementation structure member.The form of reinforcement of the steel concrete parapet that tradition is cast-in-place, to adopt double-deck steel mesh reinforcement form, as shown in Figure 1, reinforcing bar is thin and many, if directly this connected mode is transformed into to prefabricated parapet, the roofing back will stretch out double very close reinforcing bar, want pre-buried thin and close double sleeve 7 in prefabricated parapet simultaneously, the reinforcing bar that the prefabricated parapet of on-site hoisting is difficult to the roofing back is stretched out while installing is inserted in prefabricated parapet inner sleeve simultaneously, and the later stage workload of grouting is very large, therefore hoisting difficulty is large, long construction period, waste of material is many, can not fully demonstrate industrialized advantage.
The utility model content
The utility model, for the prior art deficiency, provides a kind of prefabrication and assembly construction construction of being convenient to, and saves material, the prefabricated parapet steel bar connecting structure of convenient construction.
The utility model is achieved through the following technical solutions:
A kind of prefabricated parapet steel bar connecting structure, comprise the prefabricated roof superposed beam of prefabricated parapet and prefabricated parapet below, the pre-buried single zinc-plated corrugated steel tube in center in described prefabricated parapet; The pre-buried single reinforcing bar of described prefabricated roof superposed beam, this single reinforcing bar stretches out the prefabricated roof superposed beam and is arranged in single zinc-plated corrugated steel tube.
Described single zinc-plated corrugated steel tube top seal, also be provided with top slurry outlet and bottom grout hole on single zinc-plated corrugated steel tube.
The internal diameter of described single zinc-plated corrugated steel tube is than more than the large 40mm of single bar diameter.
Compared with prior art, the beneficial effects of the utility model are:
Stretch out specification and the pre-buried single zinc-plated corrugated steel tube of spacing of reinforcing bar when 1, prefabricated parapet is prefabricated according to the superimposed back of roofing, relative and conventional sleeve connected mode, the quantity of zinc-plated bellows reduces, and prefabricated operation is simplified, good economy performance; When 2, the prefabricated parapet on-site hoisting of pre-buried single zinc-plated corrugated steel tube falls, with the superimposed back of roofing, to stretch out docking of reinforcing bar easier, the quickening of lifting speed, reduction of erection time; 3,, owing to having adopted single zinc-plated corrugated steel tube, on-the-spot grouting efficiency improves.
the accompanying drawing explanation
The structural representation that Fig. 1 is prior art parapet steel bar connecting structure;
The structural representation that Fig. 2 is the prefabricated parapet steel bar connecting structure of the utility model;
The structural representation that Fig. 3 is the single zinc-plated corrugated steel tube of the utility model.
In figure: 1, prefabricated parapet; 2, the prefabricated roof superposed beam; 3, double reinforcing bar; 4, single reinforcing bar; 5, the bottom grout hole; 6, the top slurry outlet; 7, pre-buried double sleeve; 8, single zinc-plated corrugated steel tube.
The specific embodiment
Under the prerequisite that guarantees parapet self intensity and instructions for use under corresponding load case, adopt the reinforcing bar connected mode of simplification can obtain economic benefit preferably.Double reinforced bar sleeve connected mode during the utility model connects tradition changes single reinforcing bar into and connects, single zinc-plated corrugated steel tube 8 at the pre-buried internal diameter in the middle part of prefabricated parapet 1 than the large 40mm of bar diameter, welded closure will be carried out with the sheet iron plate in the top of zinc-plated corrugated steel tube, the large and larger reinforcing bar of diameter of the interior pre-buried spacing of prefabricated roof superposed beam 2, when embedded bar calculates, parapet calculated thickness h 0should get the distance of the zinc-plated bellows core of parapet to the parapet limit that is subject to curved direction.
The prefabricated making of prefabricated roof parapet, adopt single reinforcing bar 4 connected modes, and wherein pre-buried single zinc-plated corrugated steel tube 8 in parapet, stay on zinc-plated corrugated steel tube and set section's grout hole 5 and top slurry outlet 6 simultaneously; Prefabricated parapet on-site hoisting and form of construction work, during the lifting of prefabricated parapet, reserved reinforcing bar out on the roofing superposed beam is inserted in the zinc-plated bellows of adjusting at the bottom of prefabricated parapet, be in the milk in the grouting mouthful of the bottom of prefabricated parapet, can be stopped grouting after the grout outlet pulp of top.
The utility model substitutes double sleeve connecting reinforcement in former prefabricated parapet with single bar reinforcement, with pre-buried zinc-plated corrugated steel tube, inserts the sleeve connection that the reinforcing bar post-grouting has replaced reinforcing bar.The parapet that the roofing height is not too high requires lower member as structural strength, adopts the link technique of this simplification, fully demonstrates flexibility and the economy of prefabrication and assembly construction technology.
