Description

Large-section PEC column

Technical Field

The utility model relates to the field of PEC construction, in particular to a large-section PEC column.

Background

Conventional PEC columns are typically prefabricated at the factory, but for large PEC columns, the overall cost is high due to their large weight, which is prefabricated. And because the general PEC column is prefabricated in advance, after pouring, a connecting node with the beam is reserved on the PEC column for later pouring again. Because the node is formed by pouring in batches twice, the concrete structure at the node is weak and easy to crack.

Traditional concrete placement flow is for pouring into the concrete earlier, then uses the vibrting spear to vibrate the concrete closely knit, because the high height of post, if insert the vibrting spear in the later stage, thereby can probably be blockked by the stiffening plate in the post and can't carry out effective vibration to the bottom.

In view of the above, the present invention has devised a large-cross-section PEC column, which results therefrom.

Disclosure of Invention

The utility model provides a large-section PEC column which has the characteristics of on-site integrated pouring and convenience in construction; specifically, the utility model is realized by the following technical scheme:

a large-section PEC column comprises an H-shaped steel column for supporting and concrete wrapped outside the H-shaped steel column, wherein a weak shaft bracket and a strong shaft bracket are arranged on the column body of the H-shaped steel column; the weak shaft bracket is connected to a web plate of the H-shaped steel stand column, and the strong shaft bracket is connected to a flange of the H-shaped steel stand column; a guide hole is formed between the weak shaft bracket and the H-shaped steel stand column, and the guide hole is communicated with the stand column space above the weak shaft bracket, the internal space of the weak shaft bracket and the stand column space below the weak shaft bracket.

By adopting a cast-in-place method, the bracket nodes in the weak axis direction of the PEC column and the column body are cast together, so that the number of nodes needing to be cast again at the later stage is reduced, and the construction period can be shortened; through setting up the guide hole, the concrete of being convenient for pours into completely on shaft structure and bracket from the top to the end, improves overall structure's fastness and integrative performance.

Furthermore, the joint of the flange side of the H-shaped steel column and the weak shaft bracket is provided with an L-shaped steel plate, and the L-shaped steel plate is welded with the H-shaped steel column and the weak shaft bracket respectively.

Because the space that stand flange side and weak axis bracket enclosed is a right angle, can be more complicated with traditional mould method of sealing, for example adopt two templates to fix respectively in the junction, so can appear the gap between two templates, pour the back quality relatively poor, work load increase simultaneously. This application has adopted welding one rather than shape assorted L shape steel sheet, has solved this problem, accomplishes pouring to the weak axis bracket when pouring the stand, and need not to demolish this piece of steel sheet after pouring.

Further, the weak axis bracket is made of H-shaped steel, and a web plate of the weak axis bracket is parallel to a flange of an H-shaped steel column of the PEC column.

The weak axis bracket is made of H-shaped steel, so that the structural support strength is improved, and meanwhile, the subsequent pouring is facilitated.

Further, a stand column sealing template is arranged outside the H-shaped steel stand column, and a weak shaft bracket sealing template is arranged outside the weak shaft bracket.

Further, the upright post sealing template is arranged between two flanges of the H-shaped steel upright post and connected with the upright post, an enclosing space is enclosed by the upright post sealing template and the flanges, and concrete is poured in the enclosing space; the weak shaft bracket sealing template is arranged between two flanges of the H-shaped steel of the weak shaft bracket and connected with the two flanges, an enclosed space is enclosed by the weak shaft bracket sealing template and the flanges, and concrete is poured in the enclosed space; the upright post sealing template or the weak axis bracket sealing template is clamped by a clamp to complete the connection with the H-shaped steel upright post or the weak axis bracket.

The pouring space is formed through the template, pouring work is completed, the home owners of the stand columns and the brackets can be completed simultaneously, a whole body is formed, and weak nodes caused by twice pouring are avoided.

Detailed Description

The utility model is further described with reference to the following figures and detailed description.

As shown in fig. 1 and 3, the PEC column with a large cross section comprises an H-shaped steel column 1 for supporting and concrete wrapped outside the H-shaped steel column 1, wherein a bracket is arranged on the column body of the H-shaped steel column 1 of the PEC column; according to different connection positions of the bracket and the H-shaped steel upright post 1, the bracket is divided into a weak shaft bracket 2 and a strong shaft bracket 3; the web plate of the H-shaped steel upright post 1 is connected with a weak shaft bracket 2, and the flange of the H-shaped steel upright post 1 is connected with a strong shaft bracket 3; the weak axis bracket 2 and the strong axis bracket 3 are both H-shaped steel, so that a web plate of the weak axis bracket 2 connected to a web plate of the H-shaped steel upright post 1 is parallel to a flange of the H-shaped steel upright post 1 of the PEC post; the web of the strong shaft bracket 3 connected to the flange of the H-shaped steel column 1 is parallel to the web of the H-shaped steel column 1 of the PEC column.
