Abstract
The utility model discloses a split water-stop wall-through bolt, wherein the structure thereof includes a screw rod and fixing nuts at two ends, a water-stop piece and a position-limiting piece are welded in the middle section of the screw rod, and a columnar rubber filling block is connected to the screw rod at the external end of the position-limiting piece. Due to the adoption of the utility model, a cavity which has the same size and shape as the rubber filling block is formed at the periphery of the screw rod after the concrete pouring is completed, a templates is removed, and the rubberfilling block is taken off, so that the screw rod cutting and removing tool cam extend into the cavity to cut and remove the screw rod. Therefore, the procedures of removing concretes on the periphery of the screw rod are saved; and since the reserved holes on the concrete surface have the same size, the subsequent technique of processing the concrete surface is simplified, and the whole viewingeffect after the repair is improved.
Description
Technical field
The utility model relates to a kind of building engineering construction apparatus, and is specifically a kind of to drawing the sealing through-wall bolt.
Background technology
In the existing mine dam body construction, need be by to drawing the sealing bolt to come the template of fastening concreting.At present, be made up of the set bolt at screw rod and two ends drawing the sealing through-wall bolt, screw rod partly is made up of the screw portion through walls at middle part and the standing screw at two ends, is welded with sealing sheet and banking stop at screw portion through walls.Build finish after, the template of dismantling, again with the standing screw at two ends part from the root excision, only with threaded shank fractionation through walls in body of wall.Excision is during standing screw, needs earlier just that the concrete of screw rod periphery removes, and carries out the screw rod excision again, uses the mortar of removing stone with the label concrete to carry out concrete surface at last and handles.It is not only time-consuming that follow-up needs cut concrete process, and the repairing quality index is low, influences whole impression effect.
The utility model content
It is a kind of to drawing the sealing through-wall bolt, with screw rod excision and the concrete surface renovation technique behind the simplification stripping that the purpose of this utility model will provide exactly.
The utility model is achieved in that this comprises the hold-down nut at screw rod and two ends to drawing the sealing through-wall bolt, is welded with sealing sheet and banking stop in the screw rod stage casing, and cross-under has the column rubber cushion blocks on the screw rod of banking stop outer end.
The utility model adopts this structure, installs template outside rubber cushion blocks, and the outer pad of template is gone up the lumps of wood and steel pipe, and by the hold-down nut that screws two ends template is compressed, and carries out pouring construction.After concreting finished, stripping took off rubber cushion blocks and promptly forms and the rubber cushion blocks equal and opposite in direction at the periphery of screw rod, and the hole of shape unanimity so can stretch into the screw rod resecting tool this hole easily and carry out screw rod excision operation.Like this, the concrete that has not only saved the screw rod periphery removes operation, and because concrete surface preformed hole size is consistent, also makes the concrete surface treatment process of postorder simplify, and the whole impression effect after the reparation also is improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Figure 1, this comprises the hold-down nut 8 at screw rod 3 and two ends to drawing the sealing through-wall bolt, is shaped on screw thread at the screw rod two ends.Be welded with sealing sheet 4 and two banking stops 2 in the stage casing of screw rod, cross-under has rubber cushion blocks 1 on the screw rod of banking stop 2 outer ends.Rubber cushion blocks 1 can be cylindric, prism-shaped or suitable shape such as round table-like.
When the utility model uses, install template 5 in rubber cushion blocks 1 outside, the outer pad of template is gone up the lumps of wood 6 and steel pipe 7, and the hold-down nut 8 that screws two ends again compresses template 5, carries out pouring construction.
Claims (1)
1, a kind of to drawing the sealing through-wall bolt, comprise the hold-down nut (8) at screw rod (3) and two ends being welded with sealing sheet (4) and banking stop (2) in the screw rod stage casing, it is characterized in that cross-under has rubber cushion blocks (1) on the screw rod of banking stop (2) outer end.
