Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a simple vertical control positioning device for H-shaped steel. Background Art

[0002] H-shaped steel is the main load-bearing component in the SMW method retaining wall. The verticality of the H-shaped steel during insertion will directly affect the overall safety of the support system and the construction quality of the main structure of the retaining wall. When the verticality is not well controlled and the H-shaped steel is tilted during insertion, not only will the purlin and H-shaped steel be unable to fit closely and bear the force together, causing the cement soil to crack and penetrate, affecting the overall safety and quality, but also when the H-shaped steel is pulled out after the subsequent construction is completed, the skewed H-shaped steel is easily damaged and deformed during the extraction process, and may also cause cracks in the outer wall of the underground structure if the extraction force is too large. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a simple vertical control and positioning device for H-shaped steel, which can ensure the verticality of the H-shaped steel when it is inserted, and avoid the H-shaped steel from tilting when it is inserted, which affects the construction quality and the subsequent recovery and extraction of the H-shaped steel.

[0004] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0005] The invention relates to a simple vertical control and positioning device for H-shaped steel, characterized in that it comprises a positioning frame, a vertical measuring instrument and a horizontal measuring instrument; the positioning frame comprises an upper frame, a bottom frame and a plurality of longitudinal connecting rods, the lower edge of the upper frame and the upper edge of the bottom frame are respectively connected to the upper and lower ends of the longitudinal connecting rods, and the longitudinal connecting rods are arranged along the circumference of the upper frame, the upper frame and the bottom frame are parallel to each other, and both the upper frame and the bottom frame are provided with rectangular insertion holes; the vertical measuring instrument is installed on the longitudinal connecting rod, and the horizontal measuring instrument is installed on the upper frame or the bottom frame.

[0006] In the above-mentioned simple vertical control positioning device for H-beam, usually, the rectangular insertion hole matches the shape of the H-beam. When in use, you only need to place the positioning device directly on the ground, and you can fine-tune the position through the vertical measuring instrument and the horizontal measuring instrument. When the verticality and horizontality of the positioning device meet the requirements, you only need to insert the H-beam from the two rectangular insertion holes into the already constructed mixing piles in turn. Under the restrictions of the upper frame and the bottom frame, the verticality of the inserted H-beam can be guaranteed, thereby ensuring the construction quality, and when the subsequent construction is completed and the H-beam is pulled out, the H-beam can be smoothly pulled out and recovered without affecting the constructed parts.

[0007] In the preferred embodiment, the bottom frame is provided with outwardly extending transverse extensions on both sides. The transverse extensions can increase the contact area between the positioning device and the ground when placed, avoid the influence of uneven ground, make the placement more stable, and facilitate the adjustment of verticality and horizontality.

[0008] In a further preferred embodiment, the lateral extension portion includes two lateral extension rods and an end connecting rod, the inner ends of the two lateral extension rods are respectively connected to the front and rear ends on the same side of the bottom frame, and the outer ends of the two lateral extension rods are respectively connected to the two ends of the end connecting rod.

[0009] In a further preferred embodiment, the transverse extension rods and the end connecting rods are both made of channel steel.

[0010] In a preferred embodiment, the upper frame and the bottom frame are both square.

[0011] In a further preferred embodiment, the upper frame and the bottom frame are respectively welded by four grooves, and the space surrounded by the four grooves constitutes the rectangular insertion hole. The positioning frame composed of grooves is simple to assemble.

[0012] In a further preferred embodiment, the number of the longitudinal connecting rods is four, and the four longitudinal connecting rods are respectively connected to the four corners of the upper frame and the bottom frame. The longitudinal connecting rods can also be grooved bars and directly welded to the four corners of the upper frame and the bottom frame.

[0013] In a further preferred embodiment, the groove bars and the longitudinal connecting rods are both made of aluminum alloy, which can reduce weight.

[0014] The beneficial effect of the utility model is that the simple vertical control and positioning device for H-shaped steel can ensure the verticality and horizontality of the H-shaped steel when it is inserted, and avoid the H-shaped steel from tilting when it is inserted, which affects the construction quality and the subsequent recovery and extraction of the H-shaped steel.
