Fig. 1 is a schematic structural diagram of an expansion water stop screw 100 according to an exemplary embodiment of the present application.

As shown in fig. 1, the expansion waterstop screw 100 provided by the present application may include an inner rod assembly and an outer rod assembly. The inner rod assembly comprises an inner rod main body 101, two limiting pieces and a putty-type expansion water stop ring 103, wherein the putty-type expansion water stop ring 103 is sleeved on the inner rod main body 101, and the two limiting pieces are respectively installed on two sides of the inner rod main body 101. Outer pole subassembly is including setting up in two outer pole units of interior pole main part 101 both sides, and two outer pole units all include outer pole main part 111 and locking unit, and outer pole main part 111 can be dismantled and connect in interior pole main part 101, and one side that outer pole main part 111 deviates from interior pole main part 101 is located to the locking unit cover to be used for the locking of outer pole main part 111.

It can be understood that the expansion water stop screw 100 can achieve the water stop and damping buffer effects of the basement outer wall 30 by arranging the putty type expansion water stop ring 103 on the inner rod main body 101, and has the advantages of being simple and convenient to operate, saving time and materials and the like.

It is worth explaining that putty type inflation seal ring 103 has the characteristics that the low multiplying power that slowly expands greatly, when this kind of rubber soaks in water, hydrophilic base can react with water and generates the hydrogen bond, expand by oneself, can be with the space between interior pole main part 101 and putty type inflation seal ring 103, the space inflation between putty type inflation seal ring 103 and the concrete is filled, thereby reach the condition of blocking isolation basement outer wall 30 infiltration water, compare in traditional syllogic stagnant water screw when carrying out the form removal, stagnant water screw and concrete outer wall can receive the disturbance unavoidably, narrow and small space can appear unavoidably between the two, outdoor water can be indoor through the narrow and small infiltration of space, and adopt putty type inflation seal ring 103, not only can play the effect of shock attenuation buffering, can also reach the stagnant water effect through its self-expanding effect that meets water produced.

It is worth also saying that, compared with the product type water-swelling water stop ring, the putty type water-swelling ring is more suitable for sealing the reinforcing steel bar and the rod body, and the putty type water-swelling ring adopted in the position has the characteristics of simple installation and convenience in construction.

In this embodiment, the inner diameter of the putty-type expansion water stop ring 103 is the same as the rod diameter of the inner rod body 101. It can be understood that after the inner diameter of the expansion water stop ring is the same as the rod diameter of the inner rod main body 101, the structural stability of the putty type expansion water stop ring 103 installed on the inner rod main body 101 can be improved, and the phenomenon that the putty type expansion water stop ring 103 slides is avoided.

Optionally, the inner diameter of the putty-type expansion water stop ring 103 is 12mm, the thickness thereof is 7mm, and the height thereof is 20mm.

Specifically, the distance from the second preset end face to the putty type expansion water stop ring 103 is smaller than the distance from the first preset end face to the putty type expansion water stop ring 103, so that the first preset end face with the larger outer diameter can be mutually abutted to the template 20, the stressed area between the abutted cone nut 102 and the template 20 is larger, and the supporting balance effect is better.

In this embodiment, the outer rod main body 111 is provided with an external thread 1111, and both ends of the inner rod main body 101 are respectively provided with a connecting groove (not shown), and an internal thread (not shown) adapted to the external thread 1111 is provided in the connecting groove.

It can be understood that the outer rod main body 111 and the inner rod main body 101 are in threaded connection, and have the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like, so that when the dismounting operation is facilitated, only the outer rod main bodies 111 at two ends are dismounted along the direction of threads, then the cone nut 102 is dismounted, the waterproof anti-crack mortar repair is carried out, the waterproof coating is coated on the outer side, then the waterproof coiled material construction can be carried out, and the construction difficulty is greatly reduced.

In this embodiment, the locking unit includes a chevron-shaped clamp 112 and a double steel pipe 113, the chevron-shaped clamp 112 is screwed on the external thread 1111, the double steel pipe 113 is clamped at an opening end of the chevron-shaped clamp 112, and the double steel pipe 113 and the wall form 20 are abutted against each other.

In addition, the locking unit further comprises a limit nut 114, the limit nut 114 is screwed on the external thread 1111, and the limit nut 114 and the linear end surface of the chevron-shaped clamp 112 are mutually abutted

It is understood that the stop nut 114 may be integrally formed with the chevron-shaped clip 112, or may be separated from the chevron-shaped clip 112, and the use of the chevron-shaped clip 112 and the stop nut 114 may improve the overall tensile strength of the expansion water stop screw 100, thereby facilitating the relative fixation of the formwork 20.

The embodiment of the application further provides a water stopping device, which comprises the expansion water stopping screw rod 100 and a waterproof coating, wherein the waterproof coating is arranged at the end position of the inner rod main body 101.

This watertight fittings can realize waterproof preliminary treatment through setting up waterproof coating at the both ends of inner boom main part 101 to do benefit to follow-up waterproofing membrane construction. Specifically, the waterproof coating can be a polyurethane waterproof coating, and the polyurethane waterproof coating has the characteristics of low cost and good waterproof effect.

In the specific use process, during installation, the wall thickness is controlled through the distance between the cone nuts 102 at the two ends, and the outer side of the wall thickness is fixed by the mountain-shaped clamp 112, so that the effect of reinforcing the template 20 is achieved. When the waterproof coiled material is removed, the outer rod main bodies 111 at two ends are removed along the direction of the threads, then the cone nut 102 is removed, the waterproof anti-crack mortar is repaired, the polyurethane waterproof coating is coated on the outer side, and then the waterproof coiled material construction can be carried out.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
