Abstract

The utility model relates to a wall-through pulling rod capable of controlling the thickness of a wall. The utility model is split into three sections; the middle section of the utility model is a supporting sleeve (1) forming a frustum cone shape; the length of the supporting sleeve is identical with the thickness of a concrete wall on site; both ends of the supporting sleeve (1) are processed into holes with internal thread; pulling rods with thread (2) are screwed into the holes with the internal thread; both ends of the supporting sleeve (1) are greater than the diameter of a wall-through hole on a mould plate (5), under the action of the pulling force of the pulling rod (2) and the screwing force of nuts (4), and thus both ends of the supporting sleeve (1) are tightly clung to a face plate of the mould plate (5), ensuring the distance of two mould plates and the sealing of the wall-through hole, and preventing that the wall-through hole of the mould plate leaks slurry at the time of casting.

Description

Can control the pull bar through walls of wall thickness size

The utility model relates to the connector of building operations with template.

Existing templates pull bar through walls is made up of pull bar, nut, pad, pin plate etc., what use on the engineering is exactly this form, when the template assembling is carried out in the job site, must between two templates, install wall bushing additional or install push rod additional,, can not guarantee the wall thickness unanimity because the field machining casing length is difficult for grasping, install push rod additional and cause finished product concrete metope rusty stain again, and wall-through hole place spillage, therefore general pull bar fitting operation through walls is difficult, is difficult for guaranteeing workmanship.

The purpose of this utility model promptly is can not guarantee at above-mentioned existing pull bar through walls the problem of aspects such as wall thickness unanimity and wall-through hole place spillage, and a kind of pull bar through walls of controlling the wall thickness size is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of pull bar through walls of controlling the wall thickness size, comprise pull bar (2), pad (3) and nut (4), said pull bar through walls is divided into the left, center, right three-stage structure, its stage casing is the support set (1) of the length truncated cone identical with on-the-spot concrete wall thickness degree, the diameter at the two ends of support set (1) is all greater than the wall-through hole diameter on the template (5), and the two ends of support set (1) are in the pulling force of pull bar (2) and tightening on the panel (6) that is close to template (5) under the pressure effect of nut (4).Internal thread hole all is processed at the two ends of the support set of truncated cone (1), is screwed into threaded pull bar (2) in this internal thread hole.

The utlity model has following advantage and effect:

1. the utility model can be controlled the distance between two templates easily, and construction does not need to add tubing or install strut additional on pull bar through walls when using;

2. can utilize the two ends, stage casing with the sealing of template wall-through hole, prevent template wall-through hole spillage when casting.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structure chart that the utility model can be controlled the pull bar through walls of wall thickness size

Be described further below in conjunction with drawings and Examples:

The utility model is divided into the left, center, right three-stage structure with traditional pull bar through walls, wherein segment length is identical with on-the-spot concrete wall thickness degree, and be processed into truncated cone, two ends are processed with internal thread hole, the two ends diameter is all greater than template wall piercing bolt bore dia, make the stage casing in use can control distance between two templates, the left side section and the right section of both sides are screw mandrel (being pull bar 2), the one end screws in the silk hole, stage casing, the other end passes template one side and installs pad additional, and screw on nut, play the effect of tension two side templates.The support set 1 of truncated cone shown in Figure 2 is said stage casing, its length L is complementary with the wall thickness degree of being cast, in its both sides template 5 is housed, the panel 6 of template 5 combines with the two ends of support set 1, the endoporus two ends of support set 1 all are processed with internal thread, and be screwed into threaded pull bar 2, pad 3 and nut 4 are housed on the pull bar 2 separately, when template 5 is assembled since the two ends diameter of support set 1 all greater than the wall-through hole diameter on the template 5, in the pulling force of pull bar 2 and tightening on the panel 6 of being close to template 5 under the pressure effect of nut 4, thereby played assurance wall thickness size and blocked the template wall-through hole, prevented the effect of spillage.

Claims

1, a kind of pull bar through walls of controlling the wall thickness size, comprise pull bar (2), pad (3) and nut (4), it is characterized in that: said pull bar through walls is divided into the left, center, right three-stage structure, its stage casing is the support set (1) of the length truncated cone identical with on-the-spot concrete wall thickness degree, the diameter at the two ends of support set (1) is all greater than the wall-through hole diameter on the template (5), and the two ends of support set (1) are in the pulling force of pull bar (2) and tightening on the panel (6) that is close to template (5) under the pressure effect of nut (4).

2, the pull bar through walls of controlling the wall thickness size according to claim 1, it is characterized in that: internal thread hole all is processed at the two ends of the support set of truncated cone (1), is screwed into threaded pull bar (2) in this internal thread hole.
