Description

Can have enough to meet need dry powder mortar reinforced concrete basis

Technical Field

The utility model relates to a dry powder mortar reinforced concrete basis that can have enough to meet need belongs to construction technical field.

Background

At present, various temporary facility foundations are used as basic elements for guaranteeing the safety and civilized construction of the building industry. Either at the project site or at the material deposit. The corresponding foundations are foundation conditions for safely using equipment, and the importance of the corresponding foundations in the project construction process is self-evident.

At present, most project dry powder mortar tank foundations are cast in situ by adopting concrete, so that the material is wasted, the labor input is large, and the construction speed is slow. And the finished foundation needs to be chiseled and dismantled in the later period. Therefore, the defects of the conventional foundation construction mode are obvious.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a not only safe and reliable, have enough to meet the need convenient and fast again, but also shortcoming in order to overcome conventional construction is overcome to the dry powder mortar jar reinforced concrete basis of material saving's turnover.

In order to solve the technical problem, the utility model provides a following technical scheme:

a recyclable dry powder mortar reinforced concrete foundation comprises two precast concrete blocks, wherein each precast concrete block is pre-embedded with two hanging rings and two mortar tank fixing bolts, and the two concrete blocks are spliced into a whole by taking a splicing seam as a center; the concrete blocks are embedded with PVC pipes, and round steel with the same diameter as the PVC pipes penetrates into the PVC pipes to be connected when the two concrete blocks are spliced.

Furthermore, the concrete grade of the concrete block is not lower than C30, and a double-layer bidirectional three-level reinforcing steel bar is internally matched; the surface flatness and levelness of the concrete block are not more than 2mm/2 m.

Furthermore, the PVC pipes are arranged in the concrete block in parallel according to two parallel pipes and are arranged in the middle of the thickness of the concrete block; the length dimension of the round steel is larger than 200mm of the PVC pipe, and two ends of the round steel are respectively provided with a 100mm thread head.

Furthermore, the concrete blocks are 7-shaped structures, and the two concrete blocks are U-shaped structures after being spliced.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a can have enough to meet need dry powder mortar jar reinforced concrete basis can realize quick concatenation, safe and reliable, and material saving practices thrift construction cost, saves the labour and drops into, the utility model discloses economy is pleasing to the eye, realizes having enough to meet the need reuse, and the suggestion is along with the supporting allocation and transportation of mortar jar, has obvious safe economic advantage, but wide application and job site.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model relates to a can have enough to meet need dry powder mortar jar reinforced concrete basis, it adopts prefabricated concrete piece 4, with PVC pipe 1 pre-buried in concrete piece 4. Two concrete blocks 4 are connected by using round steel 2, and the diameter of the round steel 2 is 28 mm. And (4) processing the ends of the round steel 2 with the length of 100mm, and fixing the concrete blocks 4 by steel plate nuts for splicing. Two hanging rings 5 and two bolts 6 are pre-buried on each concrete block 4, the hanging rings 5 are respectively arranged on the side surfaces and the upper surface of the concrete block 4, and the bolts 6 are arranged on the concrete block 4.

Wherein, the concrete label of concrete piece 4 is C30 at least, sets up the reinforcing bar in it, and the reinforcing bar specification is 8 tertiary steel interval 200 of double-deck two-way diameter. The diameter of the lifting ring 5 is 16mm, and two pieces of three-level steel with the diameter of 8 need to be additionally arranged for structure reinforcement during embedding.

The PVC pipe 1 has a diameter of 32mm, is arranged in parallel and is embedded in the center of the thickness of the concrete block 4. PVC pipe 1 can be convenient for 4 concatenations of concrete piece in earlier stage and later stage turnover. The plane position of the PVC pipe 1 is shown in detail in figures 1 and 2.

The utility model discloses a can have enough to meet need dry powder mortar jar reinforced concrete foundation structure as shown in figure 1. The whole foundation is spliced by the splicing seams 3, so that the requirement of the size foundation of the mortar pipe is met. The concrete mass 4 is prefabricated in a factory, standardized, so as to guarantee its quality.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
