Description

Technical Field

[0001] The utility model relates to the field of steel plate support installation, and more specifically, to a steel plate support anchoring device for a steel grid. Background Art

[0002] Steel grid structures usually use supports to connect with the lower concrete frame-column structure, where the supports are important connection nodes. When installing the supports, anchor bolts or PVC pipes are usually pre-buried at the top of the frame column to make holes, and then grouting is performed after the support is installed. This method has problems such as difficult positioning of the pre-buried position, easy displacement due to vibration, and cutting of steel bars by drilling. The conventional post-embedded reinforcement method at the top of the column to achieve the anchoring effect has problems such as deep anchor bars, large number of anchor bars, and difficulty in reaching the anchoring depth due to collision with the frame column reinforcement. Therefore, a steel plate support anchoring device for steel grids is needed to ensure the stability of the support anchoring while improving the installation efficiency of the support.

[0019] like Figure 1 and Figure 2 As shown, the utility model provides a steel plate support anchoring device for a steel grid frame, which is used to anchor the steel plate support 6 on the top of the frame column 1, comprising:

[0020] A column top plate 4 is fixedly arranged on the top of the frame column 1 by a first chemical anchor bolt 8; a plurality of stiffening plates are fixedly arranged on the top of the column top plate 4, and the plurality of stiffening plates are enclosed to form a accommodating space for a steel plate support 6, and a bottom plate 10 of the steel plate support 6 is fixedly connected to the column top plate 4 by the first chemical anchor bolt 8;

[0021] Two lateral plates 2 are respectively fixedly arranged on both sides of the frame column 1 through second chemical anchor bolts 3; the tops of the two lateral plates 2 are respectively fixedly connected to the two ends of the column top plate 4.

[0022] In this technical solution, the column top plate 4, the lateral plate 2 and the stiffening plate form a cover structure on the top of the frame column 1, which serves as an anchoring force-bearing structure for the steel plate support 6, and is anchored on the frame column 1 of the concrete structure through the first chemical anchor 8 and the second chemical anchor 3, thereby ensuring the anchoring effect of the steel plate support 6. At the same time, compared with the pre-embedded anchor bolts, pre-embedded PVC pipe drilling or post-embedded reinforcement method, the installation process does not affect the main reinforcement of the frame column, and there is no need to locate the pre-embedded position. The structure is simple and easy to install, which can effectively improve the installation efficiency of the steel plate support 6.

[0023] In another technical solution, the first chemical anchor bolt 8 and the second chemical anchor bolt 3 are both inverted cone-shaped anchor bolts, and anchor holes are opened on the top and both sides of the frame column 1, and anchoring glue is filled between the first chemical anchor bolt 8 and the second chemical anchor bolt 3 and the corresponding anchor holes.

[0024] Specifically, to ensure the anchoring effect, four first chemical anchors 8 are set, and the pull-out force value of each first chemical anchor 8 is not less than 200KN, and the shear strength is not less than 150KN; four second chemical anchors 3 are set on each of the lateral plates 2, and the pull-out force value of each second chemical anchor 3 is not less than 140KN, and the shear strength is not less than 100KN.

[0025] During installation, first, according to the drilling diameter and depth corresponding to the specifications of the first chemical anchor bolt 8 and the second chemical anchor bolt 3, use an impact drill or a water drill to drill the corresponding anchor holes on the top and both sides of the frame column 1, clean the holes with a brush and a fan or an air cylinder, repeat 2 to 3 times and there should be no visible water in the holes; then use an electric drill to rotate and install the first chemical anchor bolt 8 and the second chemical anchor bolt 3 so that the screw rods are pushed into the corresponding anchor holes. Preferably, the rotation time of the screw rod pushed into the bottom of the hole should not exceed 30 seconds, the rotation speed cannot be less than 300 rpm and not more than 750 rpm, and the screw rod advancement speed is about 2 cm / second. Then fill in the anchoring glue, which can be made of high-temperature resistant epoxy resin, and wait for enough time to cure according to the temperature and humidity of the on-site construction environment.

[0026] In another technical solution, one end of the first chemical anchor bolt 8 is anchored in the frame column 1, and the other end passes through the column top plate 4 and the bottom plate 10 in sequence and is fixed by a nut; one end of the second chemical anchor bolt 3 is anchored in the frame column 1, and the other end passes through the side plate 2 and is fixed by a nut. After the column top plate 4 and the side plate 2 are fixed, the tops of the three are welded to form a whole as an anchoring force system of the steel plate support 6.

[0027] In another technical solution, the number of the stiffening plates is four, and the four stiffening plates enclose a rectangular accommodation space, and the plane area of ​​the accommodation space is larger than the area of ​​the bottom plate 10. The stiffening plates include a first stiffening plate 9, two second stiffening plates 7, and a third stiffening plate 5, and the two second stiffening plates 7 are arranged in parallel between the first stiffening plate 9 and the third stiffening plate 5 to form the accommodation space; and in order to facilitate the adjustment of the position of the steel plate support 6 during installation, the plane area of ​​the accommodation is larger than the area of ​​the bottom plate 10, generally slightly larger than the area of ​​the bottom plate 10, as the adjustment space of the steel plate support 6.

[0028] Furthermore, the center of the column top plate 4 coincides with the center of the accommodation space. When the stiffening plate is fixedly installed on the column top plate 4, the center of the accommodation space should coincide with the center of the column top plate 4, so as to facilitate the positioning and installation of the steel plate support 6.

[0029] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
