Abstract
The utility model provides a bending embedded connecting piece of a corrugated steel plate. A transverse fold line is arranged at a distance from the top end of the corrugated steel plate; the corrugated steel plate is cut to the transverse fold line in the longitudinal direction of a waveform turning line; a horizontal section and an inclined section of the cut steel web plate are respectively bent outward along the transverse fold line; a plurality of openings are formed below the bent parts; and reinforcing steel bars are formed in the openings in a through way. The bending embedded connecting piece has the characteristics of simple structure, convenience in construction, good structural property, low price, good engineering application value and economic benefits and the like.
Description
Technical field
The utility model belongs to the civil structure field, is specifically related to corrugated sheet steel and bends embedded connector.
Background technology
Corrugated sheet prestressed concrete composite beam bridge is a kind of novel combining structure bridge, concrete web in textural employing corrugated sheet steel replacement case beam, adopt corresponding construction measure that the steel web is connected with the concrete roof and floor, form by concrete roof, corrugated sheet, concrete floor, external and (or) the cooperative combined structure system of prestressing with bond steel bundle.
Corrugated sheet is one of the type bridge key position with being connected of roof and floor.According to the type of attachment classification, connected mode commonly used at present mainly contains several forms such as peg connector, shaped steel connector, embedded connector, perforate steel plate connector, mixed type connector.Present domestic the type bridge does not also have a kind of steel web and roof and floor joint construction form of own intellectual property still in the starting stage.Therefore, research and development a kind of more effective, applicability is wider and the steel web being convenient to construct and roof and floor joint construction to the construction that develops China's corrugated sheet prestressed concrete composite beam bridge with promote significant.
Summary of the invention
But the utility model is at present both at home and abroad the steel web and the shortcoming of concrete roof and floor connector in the existence of aspects such as stress performance and application property of corrugated sheet composite beam bridge, from simplified construction, be convenient to construct, improve aspect such as stress performance and proposed a kind of novel combining structure connector.
Realize that the utility model purpose technical scheme is: corrugated sheet steel bends embedded connector, be provided with lateral fold line apart from corrugated sheet steel top one segment distance, vertically cut to lateral fold line along the waveform bend line, steel web horizontal segment after the incision, oblique section are along lateral fold line bending laterally respectively, below bending part, be provided with plurality of opening, run through reinforcing bar in the perforate.
The utility model removes the perforate of the conventional embedded connector light plate of reservation, runs through reinforcing bar, utilize the embedding steel plate to bear outside the horizontal shear force, also can bear a part of horizontal shear force to the horizontal steel plate that both sides bend up, can be used as the balanced vertical load that transmits of frange plate simultaneously.
Described kink is angle≤90 ° of bending outwards, according to connecting portion stress performance difference, can be generally 90 ° by adjusting the length of reserving steel plate, the angle of bending, can suitably turn angle down according to the closely knit requirement of concreting, wait to change connector bearing capacity and rigidity.Simultaneously, according to shear behavior require also can be on the bending steel plate perforate and run through reinforcing bar.
The cutting, the bending that embed the end steel plate all can be finished in factory.Site operation only need run through reinforcing bar and get final product.The embedded connector of this bending has simple structure, and it is convenient to construct, structural performance good (effectively transmitting vertical load), and lower-price characteristic has excellent engineering using value and economic benefit.
The beneficial effects of the utility model are:
(1) compares with the embedded connector of routine, bend embedded connector and can reach the effect of frange plate, effectively transmit vertical load by the bending of built-in end steel plate.
(2) compare with frange plate form connector, can omit the welding of corrugated sheet steel and frange plate, save cost significantly, easy to make.Simultaneously, site operation is convenient, can guarantee that by adjusting bending angle concrete vibrating is closely knit, is more suitable for being connected of steel web and concrete floor.
Description of drawings

Fig. 1-2 is embedded connector bending back structural representation for the utility model embodiment 1 corrugated sheet steel bends;
Fig. 2 is the utility model embodiment 1 embedded connector kink plan view.
The specific embodiment
Be described further below in conjunction with drawings and Examples.
Shown in Fig. 1-1 and Fig. 1-2, corrugated sheet steel bends embedded connector, about 20cm is provided with lateral fold line 2 apart from corrugated sheet steel 1 top, vertically cut to lateral fold line 2 along waveform bend line 3, steel web horizontal segment 4 after the incision, oblique section 5 bend about 90 ° respectively laterally along lateral fold line, form kink 6, on corrugated sheet steel below the kink 6 and kink 6, be provided with plurality of opening 7, run through reinforcing bar 8 in the perforate 7.
When produce in factory, at first reserve certain altitude (about 20cm), and cut along waveform bend line 3 in corrugated sheet steel 1 end, with the steel web horizontal segment 4 after cutting, turn up about 90 ° respectively laterally for oblique section 5, formation kink 6, as shown in Figure 2.On the steel plate below the kink 6 and kink 6 on perforate so that run through reinforcing bar 8 at the scene.
After the mounting template, reinforcing bar 8 is run through at the place at the perforate steel plate at the scene, builds the roof and floor concrete, forms connector.
