Description

Precast concrete base

Technical Field

The utility model relates to the field of building materials, in particular to a precast concrete base.

Background

The precast concrete base is a common building material for municipal construction, is mainly used at the bottoms of street lamps and power towers, is buried into a foundation, plays a role in balancing weights and supporting the street lamps and the power towers, and is a precast concrete base for a tower pole, such as a precast concrete base with a patent number of CN 104563586A.

The whole size of the precast concrete base of the type is fixed, once the precast concrete is molded, the size cannot be changed, the weight of the base cannot be adjusted according to the weight of a lamp post fixed on the upper part of the precast concrete base, and the whole precast concrete base is too heavy and is troublesome to carry and move.

Disclosure of Invention

1. Technical problem to be solved

Aiming at the problems existing in the prior art, the utility model aims to provide the precast concrete base, the framework in the precast concrete base can be spliced and connected with other precast concrete base frameworks, the self weight of the precast concrete base can be adjusted by accumulating different precast concrete bases, the weight is changed according to lamp poles or power towers with different weights, and meanwhile, a plurality of split precast concrete bases are convenient to carry.

2. Technical proposal

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a precast concrete base, includes concrete and inner frame, the concrete casting is in the inner frame outside, the inner frame includes the reinforcing bar ring, the outside of reinforcing bar ring evenly welds there is the crossbeam, and the bottom side of reinforcing bar ring evenly welds there is the vertical beam.

Further, the vertical beams and the cross beams are in one-to-one correspondence, and one ends of the vertical beams are welded with sleeves.

Further, one end of the cross beam is welded with a threaded rod.

Furthermore, the threaded rods and the sleeves are in one-to-one correspondence, and in the overlook state of the inner framework, the threaded rods and the sleeves are coincided and collinear.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model are within the protection scope of the present utility model.

Referring to fig. 1 to 6, a precast concrete base includes a concrete 101 and an inner frame, the concrete 101 is poured outside the inner frame, the inner frame includes a reinforcing bar ring 123, a cross beam 124 is uniformly welded on the outer side of the reinforcing bar ring 123, and a vertical beam 125 is uniformly welded on the bottom side of the reinforcing bar ring 123.

Referring to fig. 1-4, the vertical beams 125 and the cross beams 124 are in one-to-one correspondence, and one end of each vertical beam 125 is welded with a sleeve 122, so that the butt joint connection between the inner skeletons is facilitated.

Referring to fig. 1-4, a threaded rod 121 is welded to one end of the cross member 124, so as to facilitate the butt-joint connection between the inner skeletons.

Referring to fig. 1-4, the threaded rods 121 and the sleeves 122 are in one-to-one correspondence, and in the top view state of the inner framework, the threaded rods 121 and the sleeves 122 are coincided and collinear, so that the inner framework is convenient to butt-joint and connect.

Referring to fig. 1-4, the top end of the threaded rod 121 is exposed to the top end of the concrete 101, and the sleeve 122 is exposed to the bottom side of the concrete 101, so that the butt joint connection between the inner skeletons is facilitated.
