Description

Technical Field

[0001] The utility model relates to the field of concrete construction, in particular to a lattice column positioner and a lattice column. Background Art

[0002] During the open-air and underground construction of subway stations and other places, vertical supports mostly adopt the lattice column construction technology, which has the characteristics of high strength and good rigidity, good force transmission, earthquake resistance, fire resistance and corrosion resistance, and plays a key role in the stability of the horizontal support of the foundation pit.

[0003] The construction process of lattice columns is to dig a deep casting pit vertically downward on the construction ground before excavating the foundation pit, then put the frame-type lattice columns composed of steel structures into the casting pit, and then pour concrete. After the foundation pit is excavated, vertical support columns are formed. However, since the top of the lattice column is generally located below the ground, the horizontal position and vertical accuracy of the lattice column are difficult to control, resulting in an overall unsightly lattice column after the foundation pit is excavated. In addition, the skewness of the steel structure in the concrete layer will affect the overall compressive strength of the support column, resulting in safety hazards in the support.

[0004] At present, after the lattice column is placed in the casting pit, its position needs to be adjusted in the casting pit. Also, since the top of the lattice column is located below the ground, the operation is difficult and time-consuming, and it is easy to damage the surface morphology of the casting pit. In some construction processes, the height of the lattice column is greater than the depth of the casting pit. Then, after the lattice column is placed in the casting pit, the lattice column is adjusted through the ground part. After the positioning is completed, the over-height part is cut off and then poured. Although this simplifies the adjustment process, it still takes a lot of time, causing the problem of "waiting for concrete in the hole", and a lot of steel is wasted. Summary of the invention

[0005] The utility model provides a lattice column positioner to solve the problem that it is inconvenient to adjust the position of the lattice column after it is placed in a casting pit.

[0006] To solve the above problems, the technical solution adopted by the utility model is a lattice column locator, including a locator body, the locator body includes four locating columns, the four locating columns are parallel to each other and arranged in a rectangle, the rectangle is adapted to the corresponding lattice column inner cavity cross-section, and spacing pieces are provided between adjacent locating columns.

[0007] This scheme designs a lattice column locator. The locator and the lattice column are both columnar structures, which are plugged into the upper end of the lattice column and extend above the ground as the extended part of the lattice column. The construction personnel can adjust the position of the lattice column by operating the locator. After the adjustment is completed, the locator can be pulled out and reused repeatedly. The locator is easy to use and operate, can be recycled, and is economical.

[0008] Preferably, the positioning column is an angle steel, four angle steels form a rectangle, and the right-angled sides of the angle steels are located at the vertices of the rectangle.

[0009] Preferably, the spacing member is a steel bar, and the two ends of the steel bar are respectively welded and fixed to the inner side of the panel of the adjacent angle steel. The positioner adopts the common materials for lattice column construction, which is easy to manufacture and use, and has lower cost.

[0010] Preferably, the steel rod is made of threaded steel with a diameter of 32 mm.

[0011] Preferably, three spacing members are provided between every two adjacent positioning columns to form a grid support and improve the overall strength of the positioner.

[0012] Preferably, between every two adjacent positioning columns, the spacing piece is spaced 30 cm up and down.

[0013] On the other hand, the utility model also provides a lattice column, including a lattice column body, and also including the above-mentioned lattice column locator, the locator body is inserted into the upper end of the lattice column body, the upper end of the locator body is higher than the upper end of the lattice column body, and the side of the locator column is in contact with the inner surface of the lattice column body. The lattice column of this scheme has the above-mentioned locator, after being placed in the casting pit, the position is adjusted by the upper end part of the locator on the ground, and then the lattice column can be placed by pulling out the locator, which is easy to use and operate; the position of the locator is fixed by surface contact friction, and at the same time, under the action of external force, the locator body and the lattice column body can be relatively moved to overcome the friction force, and the insertion depth of the locator can be adjusted, and the removal of the locator is convenient.

[0014] Preferably, a stop block is provided at the upper part of the inner cavity of the lattice column body, and the lower end of the positioning column abuts against the upper surface of the stop block. The vertical position of the positioner is rigidly fixed to prevent it from being over-inserted into the lattice column and being difficult to remove.

[0015] It can be seen from the above technical scheme that the advantages of the utility model are as follows: the lattice column positioner of the present scheme is connected to the upper end of the lattice column body, extending the lattice column above the ground, and as an operating part, the positioning position of the lattice column can be quickly and conveniently adjusted, and can be quickly removed after adjustment, thereby reducing the waiting time for concrete, reducing the loss of the casting pit, and improving the construction quality; the positioner is made of common construction materials, can be used repeatedly, and has low cost; the positioner is tightly connected to the lattice column body and the relative position is adjustable, which is flexible and convenient to use.
