Abstract

The utility model discloses a rear-mounted replaceable type basement deformation joint waterproof device. The rear-mounted replaceable type basement deformation joint waterproof device comprises angle iron, wherein the angle iron is arranged on two sides of a basement deformation joint, and drill holes in the two sides of the deformation joint are provided with threaded rods. Bonding layers are arranged on contact surfaces of the angle iron and the deformation joint, and a rubber waterstop is arranged on an opposite inner side of the threaded rods and above the angle iron on the two sides in a lap joint mode. A compaction device is arranged above the rubber waterstop and is fastened through nuts. According to the rear-mounted replaceable type basement deformation joint waterproof device, the waterproof device is installed on a basement water back side which is completed but not needs to be pre-embedded in advance, namely, a so-called rear-mounted type. The problems that the basement deformation joint leaks water and ordinary water prevention cannot pre-embed constructional elements on the water back side are solved. Besides, the rear-mounted replaceable type basement deformation joint waterproof device is replaceable, and therefore maintenance in the future can be conducted conveniently.

Description

Rearmounted replaceable basement waterproofing of movement joints device

Technical field

The utility model relates to the replaceable basement waterproofing of movement joints of a kind of postposition device, belongs to architectural design and waterproof construction field.

Background technology

The underground space is widely used at present, the flat shape of basement becomes increasingly complex and is irregular, and the area of basement is also increasing, how to solve the distortion of expanding with heat and contract with cold that large-area concrete of basement shrinkage strain and operational phase variations in temperature cause, and eliminate that distortion produces the disadvantageous thermal stresses of structure is become the difficult problem of design of basement and construction, the deformation joint that arranges that adopts at present is one of commonly used and effective ways that overcome the above problems, and the common way of deformation joint is: at the side wall of basement, top board, the middle part of base plate arranges rubber fastening band, fill out the water-swellable sealing rod, seam surface embedding polyvinyl chloride (PVC) cement.But produce seepage owing to following reason regular meeting causes the basement deformation joint after construction is finished: 1. rubber fastening band is of poor quality, breaks under the hydraulic pressure effect; 2. construction technology is coarse, rubber fastening band and concrete surface infiltration; 3. rubber fastening band does not seal, in the joint seepage; 4. after long-term the use, waterstop is aging.In case occur being difficult to usually after the above leakage problems repair, reason is that all parts of water-tight device are pre-buried when all being construction, and the water after the seepage produces bigger water pressure to the waterproofing course of back side.

The utility model utilizes the space between basement structure layer and the building coats, can water-tight device be installed at the basement back side of having finished, and all member designs become detachable, are convenient to keep in repair replacement in the future, have solved above-mentioned engineering roadblock effectively.

The utility model content

The utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, detachable, maintenance to replace rearmounted replaceable basement waterproofing of movement joints device easily.

The utility model is achieved through the following technical solutions:

The replaceable basement waterproofing of movement joints of a kind of postposition device comprises angle steel, and angle steel is arranged on the both sides of basement deformation joint, and the both sides boring of deformation joint arranges screw rod; Angle steel and deformation joint contact surface arrange tack coat, and both sides angle steel top, screw rod opposed inside overlap joint arrange rubber fastening band, and the rubber fastening band top arranges hold down gag, and hold down gag is fastening by nut.

Described tack coat comprises structure levelling glue-line and steel bonding glue-line.

Described rubber fastening band and angle steel contact position arrange the butyl sealant bar, and the rubber fastening band top arranges the steel press strip.

Described hold down gag is the securing member pressing plate.

The beneficial effects of the utility model are:

The utility model the basement back side finished water-tight device is installed and do not need in advance pre-buried-namely what is called is rear-mounted.

Advantage of the present utility model: 1. solve basement deformation joint seepage shipwreck topic; 2. device is for rear-mounted, solved common waterproof back side can't preburied component a difficult problem; 3. device is convenient to safeguard for replaceable in the future.

The utility model adopts bar planting technology set bolt, adopts the steel bonding technology to fix and seal on-deformable angle steel, adopt elongated steel plate to fix deformable rubber sealing rod, composite set has sealing and deformability, satisfies waterproof and the deformation requirements of basement deformation joint.
