Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated building construction, and particularly belongs to a precast fence base. Background Art

[0002] Prefabricated fences are deeply loved by users because of their short construction period, low cost and good forming effect. For the construction of existing ordinary fences, their foundations need to be formwork-supported and concreted on site, and the on-site embedding of bottom steel plates and the welding work with the bottom steel plates of precast columns are complicated, and electricity use is troublesome. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a precast fence base. The present application provides the following technical solutions:

[0004] It includes a seat body and a column; a groove is provided on the seat body, fine aggregate mortar is provided in the groove, the bottom of the column is installed in the groove, and the fine aggregate mortar is filled between the groove and the column.

[0005] A concrete cushion layer is provided at the bottom of the seat body to improve the bearing capacity of the base body at the bottom of the seat body.

[0006] A positioning structure for temporarily fixing the column is provided on the seat body. The positioning structure includes a fixing part fixed on the seat body and a clamping part closely abutted against the column. The fixing part is fixedly connected to the clamping part.

[0007] The fixing part is a fixed steel sleeve sleeved on the seat body, and the clamping part is two clamping plates fixed on the fixed steel sleeve. Through holes are provided at both ends of the two clamping plates. The two clamping plates are butted by bolts passing through the through holes on the ear plates to clamp the column. A connecting steel plate is fixedly arranged on the fixed steel sleeve and is fixedly connected to one of the clamping plates.

[0008] By providing the positioning structure, after the bottom of the column is placed in the groove, the column is temporarily fixed and positioned to prevent the column from deviating before the fine aggregate mortar is cured.

[0009] The seat body is in the shape of a truncated cone with a narrow top and a wide bottom to increase the stress area at the bottom of the truncated cone, reduce the pressure at the bottom of the truncated cone, and at the same time facilitate the sleeving of the fixed steel sleeve on the seat body.

[0010] An opening is provided on the fixed steel sleeve, and the width of the opening is greater than the width of the column.

[0011] By providing the opening, it is convenient to remove the fixed steel sleeve later.

[0012] A diversion channel is provided on the bottom wall and side wall of the groove to prevent some fine stone mortar from being blocked at the bottom of the column when the column bottom is placed into the groove, which may raise one side of the column and cause the column to tilt.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] The construction is simple. There is no need to pour a large amount of concrete for the base, nor to weld the column to the base. After the base is set up, first fill a certain amount of fine stone mortar, and then place the fence column in the groove in the middle of the base to complete the installation, with low requirements for on-site construction conditions.
