Abstract
The utility model relates to a prestressed reinforced concrete precast column. A prestressed reinforced concrete precast column body adopts the pretensioning process and is embedded with prestressed steel strands. The high-strength steel strands are used for replacing ordinary steel bars, therefore, the steel usage of the column is greatly reduced, and the manufacturing cost is lowered. The prestressed precast column manufactured by the pretensioning process has good rigidity and better durability and is convenient to install. The column body is provided with a plurality of partitioned cavities, so that the column has good integrity, bidirectional bending resistance, strong anti-torsion ability, light weight and convenient hoisting and transportation. The top end of the column is provided with an embedded bolt or an embedded ferrous part, therefore, the column is conveniently connected with a steel column of an upper column to form a combined column, the structure is reasonable, and the construction is convenient. A concrete bracket, a steel bracket or a reinforced concrete bracket is embedded with an embedded bolt or an embedded iron part so as to connect a crane beam.

Technical field
The utility model relates to the building structural element in a kind of building trade, particularly a kind of prestressed reinforced concrete prefabricated post that is used to have the driving single-storey factory building.
Background technology
There is the kind of driving single-storey factory building framed bent post to mainly contain steel column, cast-in-situ reinforced concrete column and prefabricated reinforced concrete column.Steel column cost height, steel using amount is big, and fireproof performance is poor.The cast-in-situ reinforced concrete column construction period is long, complex process, and labor intensive, because be the large eccentricity force column, post also bigger with girder steel.Prefabricated reinforced concrete column is a solid construction, and steel using amount is big, from great, and transporting and hoisting inconvenience.
The utility model content
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of prestressed reinforced concrete prefabricated post.
The main technical schemes that the utility model adopts is: a kind of prestressed reinforced concrete prefabricated post, the body of described prestressed reinforced concrete prefabricated post adopt pre-tensioning system technology to be embedded with prestress wire.
The utility model also adopts following attached technical scheme: have cavity in its body, the quantity of described cavity is a plurality of and is spaced from each other;
In the body that is embedded in described prestressed reinforced concrete prefabricated post of described prestress wire symmetry;
Side on described prestressed reinforced concrete prefabricated post top has the concrete bracket;
At least one side on described prestressed reinforced concrete prefabricated post top is embedded with the built-in fitting that is used to make steel corbel or steel bar concrete bracket;
Be embedded with pre-embedded bolt and/or embedded iron parts on the top of described prestressed reinforced concrete prefabricated post;
The end that is positioned at the steel strand of described steel bar concrete prefabricated post bottom is provided with ground tackle;
Be filled with tub, cement fibrolite plate box or foam block in the described cavity;
The position of burying steel strand in prestressed reinforced concrete prefabricated post end underground is embedded with reinforced mesh or spiral hoop;
Described prestressed reinforced concrete prefabricated post two ends 600mm is a solid to the position of 1500mm.
The beneficial effect that adopts the utility model to bring is: (1) has replaced plain bars with high-strength steel strand, thereby the steel using amount of post is declined to a great extent, and cost reduces.(2) the prestressing force prefabricated post that adopts pre-tensioning system technology to make, rigidity is good especially, can reduce column cross-section size.Easy for installation, endurance quality is better.(3) body of post has a plurality of cavitys spaced apart from each other, the good integrity of post, and two-way bending resistance, anti-twisting property is strong, and is in light weight, convenient lifting transportation.(4) on the top of post pre-embedded bolt or embedded iron parts are set, are convenient to connect the formation combined column with the steel column of upper prop, rational in infrastructure, easy construction.Being embedded with pre-embedded bolt or embedded iron parts on the steel corbel or on the steel bar concrete bracket, be used to connect crane beam.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
As shown in Figure 1 to Figure 3, be a kind of prestressed reinforced concrete prefabricated post that the utility model provides, the body of described prestressed reinforced concrete prefabricated post adopts pre-tensioning system technology to be embedded with prestress wire 1.High-strength steel strand 1 have replaced plain bars, thereby the steel using amount of post is declined to a great extent, and cost reduces.The prestressed column that adopts pre-tensioning system technology to make, when factory mass is made, low cost of manufacture.Rigidity is good, easy for installation especially, and endurance quality is better.In addition, have cavity 2 in the body of post, the quantity of described cavity 2 is a plurality of and is spaced from each other.The setting of cavity 2 makes the lighter overall weight of post, convenient transportation, lifting construction.
As shown in Figure 1 to Figure 3, the body of described prestressed reinforced concrete prefabricated post also is embedded with reinforcing bar.In the body that is embedded in described prestressed reinforced concrete prefabricated post of described prestress wire 1 symmetry.In the body that is embedded in described prestressed reinforced concrete prefabricated post of described steel strand symmetry.
The breadth of section of described prestressed reinforced concrete prefabricated post is between the 400mm-500mm, and the limited 400mm that selects for use highly is between the 400mm-1000mm, preferably to select 800mm for use.
As shown in Figure 1, in the present embodiment, the side on described prestressed reinforced concrete prefabricated post top has concrete bracket 3.On concrete bracket 3, be embedded with embedded iron parts 5, be embedded with pre-embedded bolt 4 on the top of steel bar concrete prefabricated post, be located at being used on the concrete bracket and connect crane beam, be connected to form combined column and be located at the steel column that being used on the steel bar concrete prefabricated post top connect top.
The end that is positioned at the steel strand of described steel bar concrete prefabricated post bottom is provided with ground tackle 9, is used for anchoring steel strand 1, makes the prestressing force of cylinder lower end even.
Described prestressed reinforced concrete prefabricated post two ends 600mm is a solid to the position of 1500mm.
Except that present embodiment, another scheme also is provided, in this scheme, difference is to be embedded with the embedded iron parts 8 of pre-embedded bolt 4 or band anchor pin on the roof of described precast beam end, and at least one side on prestressed reinforced concrete prefabricated post top is embedded with the built-in fitting that is used to make steel corbel or steel bar concrete bracket, steel corbel or steel bar concrete bracket are post-production and form, and built-in fitting is to provide the prerequisite basic condition for the later stage preparation.
In the process of preparation hollow column,, can place tub 6, cement fibrolite plate box or foam block in order to form cavity 2.After preparing post, described tub 6, cement fibrolite plate box or foam block just have been contained in the cavity 2.
Referring to Fig. 1 and Fig. 3, in the foregoing description that the present invention provides, the position that described steel bar concrete prefabricated post end is buried steel strand underground is embedded with reinforced mesh 7.In the foregoing description that the present invention provides, because steel strand 1 produce local failure to the cylinder concrete when putting, described reinforced mesh 7 can prevent that this position concrete from producing the crack.This reinforced mesh 7 is at least two, satisfies requirement of strength with this.
