Abstract
The utility model provides an ensure accurate pre-buried auxiliary device of beam bushing, auxiliary device can set up in buried sleeve (3), includes circular steel sheet (1) of taking centre bore (1a) that two diameters slightly are less than buried sleeve internal diameter, connects three piece at least support bars (2) of angular distribution such as between two circular steel sheets. The utility model discloses can effectively restrict the buried sleeve degree of freedom, avoid appearing buried sleeve skew and the secondary adjustment that arouses at in-process such as concrete placement.
Description
Technical Field
The utility model belongs to the technical field of embedded bushing's auxiliary device in the building installation.
Background
In the building installation engineering, a large amount of indoor beam-penetrating pipeline installation work exists, and a beam-penetrating sleeve must be installed at the beam-penetrating position of the pipeline. The common installation method of the beam-through sleeve is to bind or weld the beam-through sleeve on the beam steel bar. After the through-beam sleeve is installed, the embedded elevation or horizontal position deviation of the sleeve can be caused due to the interference of factors such as beam steel bar downwarping and concrete pouring, and the later-stage pipeline installation is influenced.
Disclosure of Invention
The utility model aims at solving the pre-buried deviation problem of the beam-penetrating casing that above-mentioned prior art exists, provide one kind can firmly fix the sleeve pipe, ensure that the beam-penetrating casing is accurate pre-buried, can block off the auxiliary device of sleeve pipe both ends in order to prevent that the concrete from getting into again.
The utility model adopts the following technical scheme:
the utility model provides an ensure accurate pre-buried auxiliary device of beam bushing, auxiliary device can set up in buried sleeve pipe in advance, includes two diameters slightly less than buried sleeve pipe internal diameter's circular steel sheet of taking the centre bore, connect three piece at least support reinforcement that the equal angular distribution between two circular steel sheets.
Circular steel sheet diameter ratio buried sleeve's internal diameter is little 1 ~ 2 millimeters, and circular steel sheet thickness is not less than 5 millimeters. The sum of the thickness of the two circular steel plates and the length of the supporting steel bars is equal to the length of the embedded sleeve.
Adopt the utility model discloses, when the buried sleeve, the circular steel sheet at auxiliary device both ends and support bar can firmly support the buried sleeve, three support bar vertical welding are between two circular steel sheets, can ensure that the centre bore of two circular steel sheets is concentric, when being fixed in auxiliary device between the both sides roof beam template through to drawing the screw rod, can not only effectively restrict the sheathed tube degree of freedom of wearing the roof beam, prevent to wear the roof beam sleeve and remove the off normal, concrete entering sleeve pipe when can also effectively preventing to pour the roof beam, the sheathed tube installation quality of wearing the roof beam has been improved, avoid the secondary repair because of the sleeve pipe aversion causes, the efficiency of construction is improved. The invention has simple structure, convenient use, strong universality and repeated use.

Detailed Description
The invention is further explained by the accompanying drawings.
The auxiliary device capable of ensuring accurate embedding of the beam-penetrating sleeve comprises two circular steel plates 1 with the diameter slightly smaller than the inner diameter of the embedded sleeve and provided with central holes 1a, and at least three support steel bars 2 which are connected between the two circular steel plates and distributed at equal angles. The three support steel bars of the embodiment are distributed at equal angles along the circumference of the circular steel plate and are vertically welded between the two circular steel plates so as to ensure that the central holes of the two circular steel plates are concentric. As shown in fig. 2 and 3, the auxiliary device is disposed in the embedment sleeve 3, and both end surfaces of the auxiliary device are flush with the embedment sleeve. In order to facilitate installation and taking out, the diameter of the round steel plate 1 is 1-2 mm smaller than the inner diameter of the embedded sleeve, and the thickness of the round steel plate is not less than 5 mm. The sum of the thickness of the two round steel plates 1 and the length of the supporting steel bar 2 is equal to the length of the embedded sleeve 3.
During construction, firstly, the beam-penetrating embedded sleeve 3 and the auxiliary device are manufactured according to drawing requirements and pipeline specifications, and then as shown in fig. 4, the beam-penetrating sleeve is ensured to be accurately embedded according to the following method steps:
a. measuring and paying off, positioning the mounting position of the embedded sleeve in the beam, and marking the position of the embedded sleeve and the central position of the sleeve on the templates 4 on the two sides of the beam in a scribing way;
b. the center of the template at the two sides of the beam is provided with a hole corresponding to the center of the embedded sleeve, and the aperture is slightly larger than the diameter of the counter-pull screw;
c. assembling the auxiliary device inside the embedded sleeve;
d. arranging the embedded sleeve equipped with the auxiliary device between the formworks 4 on the two sides of the beam;
e. b, adjusting the embedded sleeve to coincide with the scribing on the templates at the two sides in the step a, penetrating through the beam templates at the two sides and the central holes 1a of the circular steel plates 1 at the two ends of the auxiliary device by using a split screw 5, and locking by using a locking nut 6 to fix the embedded sleeve between the templates at the two sides of the beam;
f. pouring the beam by using concrete, and taking out the locking nut and the counter-pulling screw rod before the beam template is dismantled;
g. and after the template is dismantled, taking out the auxiliary device. The removed auxiliary device can be reused.
The utility model discloses an auxiliary device can be used for the steel casing pipe location, also can be used to PVC sleeve pipe location, is applicable to template systems such as wood pattern, aluminium mould, steel mould, and the commonality is good.
