Description

Pre-buried structure of prefabricated full assembly basis dowel

Technical Field

The utility model relates to the technical field of pre-buried construction methods of prefabricated full-assembled foundation dowel bars, in particular to a pre-buried structure of a prefabricated full-assembled foundation dowel bar.

Background

In the cast-in-situ foundation construction, dowel bars pre-buried in the connection of the main body structure are needed. Because the size of the reserved hole of the fully assembled prefabricated wallboard PK box is limited, the precision requirement on the reserved dowel bar of the foundation is higher. In the full assembly project, the embedded point positions of the dowel bars can be positioned through paying off, as shown in fig. 1 and 2, specifically, the dowel bar point positions are found out on a strip base 5 (strip foundation) through a paying off measuring method, and then the dowel bar holes 1 are formed by punching holes in the point positions. After the completion, clean up in the dowel hole 1, fix dowel 3 in dowel hole 1 of strip base 5 with mortar. And building a template support pouring concrete, and forming a foundation beam 4 on the strip base.

The method can better ensure the stability of the dowel bar under the condition that the height of the foundation beam is smaller (less than 500 mm), but when the height of the foundation beam is greater than 500mm, the self weight of the concrete and the construction of the vibrating rod easily cause the deflection of the template and the expansion of the template when the concrete is poured on the foundation beam, so that the pre-buried dowel bar is deflected along with the deflection, the stability of the dowel bar is influenced, and the forming quality is influenced.

The utility model aims to provide a prefabricated full-assembled foundation dowel bar pre-buried structure which can be suitable for stably installing dowel bars when the height of a foundation beam is larger than 500 mm.

The technical scheme of the utility model is as follows: the utility model provides a prefabricated full assembly foundation dowel pre-buried structure includes the strip base, locates foundation beam on the strip base, connect in a plurality of dowel bars of strip base and foundation beam, be used for pouring the side form of foundation beam, be used for the design template of being connected with the side form, the design template has been a plurality of at the length direction interval cloth of foundation beam, every be equipped with at least one dowel bar hole on the design template, the one end of dowel bar is in form in the strip base and stretch into length L, the other end of dowel bar is followed the dowel bar hole stretches out.

Preferably, the design template is connected with the side mold through a spike.

Preferably, steel bars are arranged in the foundation beam, and the dowel bars are fixed with the steel bars.

Preferably, the length L is more than or equal to 200mm.

Preferably, in the plurality of design templates spaced along the length direction of the foundation beam, the distance between every two design templates is more than or equal to 1m.

Preferably, the part of the dowel bar extending out of the dowel bar hole is a threaded section.

Compared with the related art, the utility model has the beneficial effects that: through fixed design template in order to fix the dowel on the side form, can effectively avoid making the dowel skew when pouring the concrete, guarantee the stability of dowel, guarantee the shaping quality of foundation beam.

Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 3 and 5, the prefabricated fully assembled foundation dowel bar pre-buried structure provided in this embodiment includes a bar base 5, a foundation beam 4 disposed on the bar base 5, a plurality of dowel bars 3 connected to the bar base 5 and the foundation beam 4, a side mold 8 for pouring the foundation beam 4, and a design template 7 for connecting with the side mold 8.

The side forms 8 are surrounded on four sides on the strip base 5 to form a template capable of pouring the foundation beam 4.

The design templates 7 are rectangular plates, a plurality of design templates are arranged at intervals in the length direction of the foundation beam 4, and the distance between every two design templates 7 is more than or equal to 1m.

Both ends of the design template 7 are fixed with two opposite side molds 8 by the spikes 2 (as shown in fig. 4).
