3. traditional screw rod is clipped screw rod through gas cutting after the dismounting template, process is complicated, and speed of application is slow, and body of wall is local because of receiving high temperature the cement phenomenon of bursting apart to occur.
Summary of the invention
To the problem that exists in the prior art, the purpose of the utility model provides a kind of sealing up screw, is beneficial to fast the fixedly body of wall of sealing, reduces construction costs, and is not only energy-conservation but also reduce discharging.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts provides a kind of sealing up screw; Wherein: this sealing up screw includes the end screw rod of intermediate support sleeve pipe, two symmetries; The end screw rod that the center that is provided with at the two ends of said intermediate support sleeve pipe is threaded said two symmetries of end cap in hole is connected the two ends of intermediate support sleeve pipe through end cap, is provided with the seal ring of water-swellable at the middle part of intermediate support sleeve pipe, twists respectively on the end screw rod of two symmetries and is connected to nut.
The end screw rod of said two symmetries is respectively the end screw rod that revolves screw thread about band, and the length of end screw rod is 250mm to 300mm.
The effect of the utility model is:
1. this sealing up screw is because of being provided with the water-swellable seal ring; And plastic end cover is equipped with at intermediate support pipe two ends, loosening situation can not occur, so need not use ancillary methods such as cement support, spacer; Convenient construction has been saved the auxiliary material spending on the other hand on the one hand.
2. this sealing up screw is when form removal, and the end screw rod at two ends can easy removal through rotation, and metope does not expose the obstruction of screw rod, makes template large tracts of land break away from metope once.With the striking time reduced in comparison of using traditional screw rod 10 to 20 times, improved efficiency of construction greatly, and installed, can not cause damage during dismounting template.
3. this sealing up screw need not use gas cutting fully, and non-exhaust emission is pollution-free, and body of wall is attractive in appearance smooth, and unloading process does not have damage, is beneficial to construction in later period.In the practice of construction operation, demolition, installation are convenient, and are simple to operate.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the intermediate support sleeve pipe contour structures sketch map of the utility model.
Among the figure:
1, intermediate support sleeve pipe 2, end screw rod 3, nut 4, end cap 5, seal ring
The specific embodiment
In conjunction with accompanying drawing the sealing up screw structure of the utility model is explained.
Like Fig. 1, shown in 2; The sealing up screw structure of the utility model is; This sealing up screw includes the end screw rod 2 of intermediate support sleeve pipe 1, two symmetries, and the center that is provided with at the two ends of said intermediate support sleeve pipe 1 is threaded the end cap 4 in hole, and the end screw rod 2 of said two symmetries is connected the two ends of intermediate support sleeve pipe 1 through end cap 4; Be provided with in the middle part of intermediate support sleeve pipe 1 periphery to twist respectively on the end screw rod 2 of 5, two symmetries of seal ring of water-swellable and be connected to nut 3.
The end screw rod 2 of said two symmetries is respectively the end screw rod 2 that revolves screw thread about band, and the length of end screw rod 2 is 250mm to 300mm.
The sealing up screw function of the utility model is achieved in that
The intermediate support sleeve pipe 1 of this sealing up screw adopts industrial seamless pipe, through cutting---operations such as punching press are processed, and its length can be adjusted according to the actual (real) thickness of body of wall.Before the use, fill widely used water-swellable material on the building sealing engineering in the pipe, the center periphery is provided with the seal ring 5 of water-swellable, has cancelled original locational welding sealing sheet.The two ends of intermediate support sleeve pipe 1 are equipped with the round-meshed plastic end cover 4 in center, with outer locking in the intermediate support sleeve pipe 1, guarantee that intermediate support sleeve pipe 1 is watertight.On the pipe face of intermediate support sleeve pipe 1 two side portions a plurality of dolly dimples are arranged, the two ends that are beneficial to intermediate support sleeve pipe 1 are screwed into the end screw rod 2 that revolves screw thread about band through end cap 4, through the fixing body of wall of the nut 3 of end on the screw rod 2.End screw rod 2 general length are 250mm to 300mm, and no matter the length of intermediate support pipe 1 is what, and through adjusting the length of the screw-in intermediate support sleeve pipe 1 of holding screw rod 2, use can match.
Only be intermediate support sleeve pipe 1 part to be imbedded in the cement abandon in the work progress, the end screw rod 2 at two ends is then rotatable to be pulled down, and reuses.Design here; A large amount of steel have not only been practiced thrift; In production, making, the novel sealing up screw of use, significantly reduce the use of argon arc welding and gas welding simultaneously, and then reduced the waste of the energy, reduced the discharging of carbon dioxide and heat; Reduce the pollution of construction environment, can be described as not only energy-conservation but also environmental protection.
The difference of this sealing up screw and traditional screw rod:
One, installation process
1. the spacer of traditional screw rod after because of the plastics rubber cushion has the phenomenon of snapping, and interior arch situation can appear in template, therefore needs to use cement support, spacer etc. to assist.
2. the seal ring 5 of this sealing up screw because of being provided with water-swellable; And plastic end cover 4 is equipped with at intermediate support sleeve pipe 1 two ends, loosening situation can not occur, so need not use ancillary methods such as cement support, spacer; Convenient construction has been saved the auxiliary material spending on the other hand on the one hand.
Two, unloading process
1. traditional screw rod because wall external screw rod resistance is big, so the dismounting difficulty is bigger, is wasted time and energy when the dismounting template, and the template consume is big.
2. this sealing up screw is when form removal, and the end screw rod 2 at two ends can easy removal through rotation, and metope does not expose the obstruction of screw rod, makes template large tracts of land break away from metope once.With the striking time reduced in comparison of using traditional screw rod 10 to 20 times, improved efficiency of construction greatly, and installed, can not cause damage during dismounting template.
Three, result of use
1. traditional screw rod is clipped screw rod through gas cutting after dismounting mould template, process is complicated, and construction is slow, and body of wall is local because of receiving high temperature the cement phenomenon of bursting apart to occur.
2. this sealing up screw need not use gas cutting fully, and non-exhaust emission is pollution-free, and body of wall is attractive in appearance smooth, and unloading process does not have damage, is beneficial to construction in later period.
3. this sealing up screw is in the practice of construction operation, and demolition, installation are convenient, and are simple to operate.
Four, application
The scope of application of this sealing up screw and traditional screw rod is extensive equally, and all need the engineering body of wall of sealing to be applicable to building basement wall, subway line body of wall, tunnel body of wall etc.
Points for attention
1. should follow operating sequence in the installation process.
2. the threaded portion that the end screw rod at two ends is connected with the intermediate support sleeve pipe in the installation process must be screwed.
The plastic end cover 4 at two ends must major part outwardly, the one, be beneficial to the fixing of template, take out but be convenient to the later stage.
