Abstract

The utility model provides a connecting fixture used for the fixing of heated boards of insulation composite outer walls of full cast-in-place concrete structures in site operation process. The connecting fixture comprises a link bar made of steel reinforcement whose diameter is 6 millimeters, and two fixed clamping sheets made of sheet bars whose middle parts are provided with 'I'-shaped straight joints. The utility model solves key problems of the construction of composite external wallboards of the shaped middle clip core which is on the site of concrete casting. The connecting fixture has the advantages of simple process and firmness, ensuring the flexible connection of the inner layer and the outer layer of the composite board.

Description

Connecting clamp for heat-insulating combined concrete outer wall pouring process

The utility model is at the construction field (site) in the placing of concrete heat preservation composite exterior wall process, for fixing the warming plate in the middle of it and connecting jig coupling together used warming plate in its pouring concrete in-situ layer with the two sides.

The many flat method productions in the factory for prefabrication of available coagulation soil heat preservation composite exterior wall.Being transported to the job site again installs.In the flat method manufacturing process of wall member, the connected mode of its warming plate adopts triangular form reinforcing bar or light section shaped steel to realize more outside.Yet for the direct heat preservation composite exterior wall plate of the legislation moulding of placing of concrete at the scene, last two kinds of connected modes can not solve the location of warming plate and resist the problem of the lateral pressure that causes because of the concrete discrepancy in elevation.

The purpose of this utility model be to provide a kind of when being applicable to the pouring concrete in-situ heat preservation composite exterior wall employed warming plate connect jig.This jig can locate warming plate wherein when legislation construction placing of concrete composite exterior wall securely, in the time of can resisting warming plate both sides placing of concrete, and the lateral pressure that causes because of the discrepancy in elevation after the cast to warming plate.

The utility model is finished in the following ways, adopting a diameter is 6 millimeters plain bar, and its length is the whole thickness of composite exterior wall, and the cold rolling one-tenth in compartment of terrain is flat-shaped in 100 millimeters scopes at two ends, be convex-concave shape notched bars, to increase it with the bond stress between concrete.Brushing rust protection agent in length range at last, with avoid use occur corrosion and metope rust staining this just constituted the connecting rod (1) that connects jig.Adopt a kind of rigidity preferably steel sheet make two of same shape fixedly cards (2).Should fixedly card (2) to be rounded, its thickness and diameter are determined according to the thickness of the thickness of warming plate, inside and outside concrete slab and the arrangement pitch that is connected jig.Strike out the straight joint (3) of " I " font at the fixing middle position of card (2), the length of these three seams is 20 millimeters.Have the square hole of a 3 * 3mm in the centre of " I " font, by a connecting rod (1) and two fixedly card (2) just constituted connection jig of the present utility model.

Fig. 2 is fixing card schematic diagram

Fig. 3 is the fixedly connected schematic diagram of the warming plate of cast-in-place concrete heat-preservation composite exterior wall

With reference to Fig. 1 and Fig. 2, because fixedly there is one " I " font straight joint (3) in the central authorities of card (2), after it was penetrated from connecting rod (1) one end, it can only can not retreat along unidirectional forward the moving of connecting rod (1).With reference to Fig. 3, when using the connection jig, earlier connecting rod (1) is inserted in the warming plate (6), and then fixedly card (2) penetrates from the two ends of connecting rod (1) respectively, until contacting firmly and compress, make the fixedly card (2) of both sides clamp warming plate (6) tightly and be connected securely with connecting rod (1) in vertical direction with warming plate (6) face.Colligation is on the reinforcing bar of the layer of concrete (4) (5) of warming plate (6) both sides before placing of concrete at connecting rod (1) two ends, and the template of exterior wall both sides is withstood in (1) two termination of connecting rod, has guaranteed to connect the normal position of jig.

The utility model once was used for 18 layers of full cast-in-place structural dwelling house high building, and thick 300 millimeters altogether of exterior walls adopt 50 millimeters thick polystyrene foam plastics to make heat-insulation layer (6). Thick 150 millimeters of the cast-in-place concrete (4) of inside structure layer, the cast-in-place concrete (5) thick 100 of outside maintenance level Millimeter has shared cover surplus this kind connection jig 2000, and, fixation simple with technology, maintenance the characteristics such as flexibly connect and satisfied the use requirement, have reached expected effect.

Claims

1, a kind of connection jig for the insulation layer position in the fixing composite thermo-insulating wall board is characterized in that the reinforcing bar that a two ends 100mm length range has concavo-convex distortion makes.Constitute connecting rod＜1 that connects jig 〉, penetrate respectively from two ends on it that a slice middle position strikes out " I " font straight joint and the center has less than connecting rod＜1〉fixing card＜2 of the garden shape of the square through-hole of the diameter of reinforcing bar 〉, constituted the connection jig of heat preservation composite exterior wall.

2, connection jig according to claim 1, it is characterized in that two fixedly the connecting rod＜1〉between card＜2〉part need scribble antirusting paint.
