Description

Water stopping device for concrete construction joint

Technical Field

The utility model relates to a construction field, concretely relates to concrete construction joint sealing device.

Background

The existing building engineering roof board, foundation slab or wall body mostly has the problem of water leakage, the main reason is structural water leakage caused by the reason that construction joints are not constructed in place, and the construction joints refer to joints formed between the concrete poured before and after due to design requirements or construction requirements in the concrete pouring process. The construction joint is not a real existing joint, and only because the initial setting time of the first poured concrete is longer than the initial setting time, a joint surface exists between the first poured concrete and the later poured concrete, the joint surface is called as the construction joint, and if the pouring treatment measures at the joint of the construction joint are improper, the leakage problem can occur.

Based on the above problem, the prior art proposes to set up the waterstop before the construction joint is pour, connects the waterstop pouring in construction joint department to avoid the seepage of construction joint department, but the concrete pouring in-process, the extruded dynamics of concrete flow makes the waterstop aversion easily, leads to the waterstop not fine fix in construction joint department.

SUMMERY OF THE UTILITY MODEL

To exist not enough among the prior art, the utility model provides a concrete construction joint sealing device to solve the problem of fixing in construction joint department that the waterstop can not be fine.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

concrete construction joint sealing device, including the waterstop and fix the locating plate on the waterstop, locating plate and waterstop set up perpendicularly, and the one end that the waterstop was kept away from to the locating plate is equipped with a plurality of vertical draw-in grooves along length direction, has the movable plate along length direction sliding connection in the locating plate, and movable plate one end is stretched out the locating plate and is fixed with the handle, is equipped with the spread groove with draw-in groove matched with on the movable plate, and the one end both sides threaded connection who is close to the handle on the locating plate has the bolt, and the bolt tip runs.

Compared with the prior art, the utility model discloses following beneficial effect has:

the clamping groove is clamped on the building steel bar structure, so that the lower surface of the water stop belt is attached to the upper surface of the steel bar structure. For the steel bar structure who adapts to not unidimensional, the pulling movable plate for the position width of spread groove and draw-in groove coincidence reduces, with the less steel bar structure of chucking size, avoids concrete placement process to stop the hosepipe and removes, behind the chucking steel bar structure, screws the bolt, and the fixed movable plate then carries out concrete placement. The water stop belt is fixed at the position to be poured through the matching of the positioning plate and the moving plate, and the water stop belt is prevented from shifting in the pouring process.

Drawings

Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.

Fig. 2 is a front view of an embodiment of the present invention.

Fig. 3 is a right side view of the embodiment of the present invention.

In the figure: the water stop comprises a water stop belt 1, a groove 2, a positioning plate 3, a moving plate 4, a clamping groove 5, a bolt 6 and a handle 7.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, and specific embodiments will be given.

As shown in fig. 1, 2 and 3, the concrete construction joint water stopping device comprises a water stopping belt 1 and a positioning plate 3 fixed in the middle of the lower surface of the water stopping belt 1, the water stopping belt 1 is flat, the water stopping belt 1 is made of an iron plate or a rubber plate, a plurality of grooves 2 are formed in the upper surface of the water stopping belt 1, the grooves 2 are arranged along the length direction of the water stopping belt 1, and the grooves 2 are arranged in parallel.

Locating plate 3 and waterstop 1 set up perpendicularly, and 3 length direction settings along the waterstop 1 of locating plate, and 3 lower extremes of locating plate are equipped with a plurality of vertical draw-in grooves 5 along length direction, are equipped with the spout along length direction in the locating plate 3, and spout and draw-in groove 5 intercommunication, 3 left ends of locating plate seal, spout right-hand member opening, and lateral sliding connection has movable plate 4 in the locating plate 3, and movable plate 4 is hollow to be set up to reduction device weight and reduction material cost.

The right end of the movable plate 4 extends out of the sliding groove and is fixedly provided with a handle 7, the movable plate 4 is provided with a connecting groove matched with the clamping groove 5, the length and the width of the connecting groove are equal to those of the clamping groove 5, when the movable plate 4 is completely positioned in the sliding groove, namely, when the left end of the movable plate 4 is abutted against the left end of the sliding groove, the clamping groove 5 is completely coincided with the connecting groove, when the movable plate 4 slides rightwards, the connecting groove is staggered with the clamping groove 5, and the width of the. Rubber pads are bonded on the inner walls of the connecting grooves and the clamping grooves 5.

Bolts 6 are connected to two sides of the upper right end of the positioning plate 3 in a threaded mode, the end portions of the bolts 6 penetrate through the positioning plate 3 and abut against the moving plate 4, and when the bolts 6 are screwed tightly to abut against the moving plate 4, the moving plate 4 can be fixed at the position.

After setting up the construction steel bar structure, before the concrete placement construction, install this device in advance in the position of structural design construction joint, the concrete mounting means of this device is: during initial condition movable plate 4 is located the spout completely, with draw-in groove 5 joint on building steel bar structure for the laminating of 1 lower surface of waterstop and steel bar structure upper surface.

For adapting to the steel bar structures of different sizes, the movable plate 4 can be pulled by the handle 7, so that the width of the position where the connecting groove and the clamping groove 5 coincide is reduced, the steel bar structure with a small clamping size is used for avoiding the stop of the movement of the water hose 1 in the concrete pouring process, rubber pads are arranged on the inner walls of the connecting groove and the clamping groove 5 and have certain deformability, the steel bar structure is clamped by deformation of the rubber pads, the friction between the positioning plate 3 and the movable plate 4 and the steel bar structure is also increased, and a certain limiting effect is realized in the vertical direction.

Bolt 6 is screwed behind the chucking steel bar structure, and fixed movable plate 4 then can carry out concrete placement, and 1 surface of waterstop sets up recess 2, can be with 1 firm connections of waterstop in the concrete after the concrete stream advances to solidify in the recess 2.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
