The utility model discloses to the drawknot between the inside and outside template of drawing structure mainly used wall form, ensure that the interval of inside and outside template can satisfy the designing requirement, mainly bear the lateral pressure and other loads of concrete.

When the device is used, the screw cap and the screw nut are respectively positioned outside the two templates to be oppositely pulled, the middle part of the screw rod is positioned between the two templates to be oppositely pulled, the length of the sleeve is adapted to the distance between the two templates to be oppositely pulled, the sleeve is sleeved at the middle part of the screw rod between the two templates to be oppositely pulled, and the screw rods at the two ends of the sleeve are provided with the gaskets; to prevent slurry leakage.

Compared with the prior art, the utility model has the following advantage:

1. convenient loading and unloading and recyclable: the utility model discloses to drawing structure including rectangular bolt, sleeve pipe and with the nut that rectangular bolt cooperation was used, when the concrete wall body dress mould, form removal, only need on rectangular bolt screw up the nut on one side can, loading and unloading are convenient quick; the nut can be directly screwed off by a wrench after the form removal without cutting by other cutting tools, so that the forming die is convenient and fast, and the whole bolt can be repeatedly recycled because the sleeve is movably sleeved at the middle part of the screw rod, so that the material is saved, and the utilization rate is improved.

2. The utility model discloses be equipped with the scale mark on the screw rod of rectangular bolt, on the one hand can accurate control template interval, can real time monitoring template deformation condition in concrete placement and the process of vibrating, in case the deviation appears can in time take corresponding treatment, improve the engineering quality; on the other hand, compare in prior art artificially take the ruler to check the template interval in proper order, the existence of scale mark can greatly reduce the work load of template acceptance engineering, improves and checks the acceptance efficiency.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. Referring to fig. 1: the utility model provides a concrete wall beam template opposite-pulling structure; the method is characterized in that: the split structure comprises a long bolt, a sleeve 9 and a nut 8; the scale mark 6 is arranged on the screw rod 1 of the strip bolt, the sleeve 9 is movably sleeved in the middle of the screw rod 1, and the nut 2 and the nut 8 are arranged at one end of the strip bolt.

The screw rod 1 provided with scale marks 6 of the strip bolt is used for penetrating through the two templates 4 to be oppositely pulled; the sleeve 9 is used for sleeving the part of the screw 1 between the two templates 4 to be oppositely pulled; the nut 8 is used for screwing in the part of the screw rod 1 extending out of the template and clamping the middle two templates 4 to be oppositely pulled.
