Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a steel box with a foundation reserved hole. Background Art

[0002] A thin steel plate box is used as the foundation reserved hole. The steel box will not be taken out and will be connected to the concrete foundation as a whole to facilitate the subsequent installation of bolts.

[0003] For example, Chinese patent CN108118893A discloses a template structure for reserving embedded bolt holes for equipment foundations in cast-in-place concrete, including a reserved hole box composed of a bottom and surrounding steel plates fixedly connected and assembled, the reserved hole box being fixedly arranged in a concrete foundation, the interior of the reserved hole box being used for pouring internal concrete, and the internal concrete being used for fixing anchor bolts.

[0004] The reserved hole box is formed in one piece, and a reserved hole box of appropriate length cannot be combined according to the required embedded depth and bolt length, resulting in material waste.

[0005] Therefore, we propose a steel box with foundation reserved holes to solve the above problems. Utility Model Content

[0006] Aiming at the problem that the reserved hole box is integrally formed and a reserved hole box of appropriate length cannot be combined according to the required embedded depth and bolt length, resulting in material waste, the utility model provides a basic reserved hole steel box.

[0007] The solution adopted by the utility model to solve the technical problem is: a steel box with a basic reserved hole, comprising a basic box and N groups of splicing boxes, wherein the N groups of splicing boxes are stacked from top to bottom, the splicing boxes on the lower layer are detachably connected to the basic box, and two adjacent splicing boxes are detachably connected;

[0008] Four reinforcing ribs are installed on both sides of the splicing box, and the inner ends of the reinforcing ribs extend into the splicing box;

[0009] Four threaded ribs are installed on both the front and rear sides of the splicing box, and the inner ends of the threaded ribs extend into the splicing box.

[0010] Preferably, two docking pieces 1 are welded on the inner edge of the top of the basic box.

[0011] Preferably, two symmetrically arranged butt joint pieces 2 are welded to the inner edge of the top of the splicing box, and two symmetrically arranged angle steels are welded to the inner edge of the bottom thereof, and a gap exists between the angle steels and the inner wall of the splicing box to form a plug-in slot;

[0012] The upper end of the first docking piece or the second docking piece is inserted into the plug-in slot.

[0013] Preferably, two threaded holes one are provided on the docking piece one, two threaded holes two are provided on the docking piece two, and two threaded holes three are provided on the angle steel.

[0014] Preferably, the inner end of the threaded rib is threadedly passed through threaded hole one or threaded hole two and is threadedly connected to threaded hole three.

[0015] Preferably, a reinforcement frame is mounted on the outer side of the splicing box.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model provides a plurality of detachable splicing boxes, and can select a suitable number of splicing boxes for assembly according to the embedded depth and bolt length, thereby controlling the length of the steel box and avoiding waste of materials.

[0018] 2. The utility model can connect the second butt piece with the angle steel during assembly by setting threaded ribs to ensure the stability of the connection between two adjacent splicing boxes. After assembly, the reinforcing ribs and both ends of the threaded ribs cross between the foundation concrete and the secondary grouting to ensure that the grouting inside the splicing box wraps the bolt part and the foundation concrete outside the splicing box form a whole, ensuring the pull-out resistance of the bolt after installation, as well as the operating life and safety of the equipment under multiple loads such as vibration.

[0019] 3. The utility model strengthens the splicing box by setting a reinforcement frame to prevent lateral pressure deformation during concrete pouring. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1-4 The utility model provides a technical solution for a steel box with a foundation reserved hole:

[0027] Embodiment 1:

[0028] according to Figure 1-3 As shown, it includes a basic box 1 and N groups of splicing boxes 2. The basic box 1 and the splicing box 2 are respectively made of 6 mm thick patterned steel plates. Two docking pieces 11 are welded on the inner edge of the top of the basic box 1. The two docking pieces 11 are arranged one in front and one in the back.

[0029] In this embodiment, there are three groups of splicing boxes 2, and the three groups of splicing boxes 2 are stacked from top to bottom.

[0030] Two symmetrically arranged butt joint pieces 32 are welded on the inner edge of the top of the splicing box 2, and two symmetrically arranged angle steels 31 are welded on the inner edge of the bottom. There is a gap between the angle steels 31 and the inner wall of the splicing box 2 to form a plug-in groove, and the upper end of the butt joint piece 11 or the butt joint piece 2 32 is inserted into the plug-in groove.

[0031] The first butt joint piece 11 is provided with two threaded holes 1, the second butt joint piece 32 is provided with two threaded holes 2 33, and the angle steel 31 is provided with two threaded holes 3.

[0032] Four threaded ribs 22 are installed on the front and rear sides of the splicing box 2. The inner end threads of the threaded ribs 22 pass through threaded hole one or threaded hole two 33 and are threadedly connected to threaded hole three, so that the lower splicing box 2 is detachably connected to the base box 1, and two adjacent splicing boxes 2 are detachably connected. By setting a plurality of detachable splicing boxes 2, a suitable number of splicing boxes 2 can be selected for assembly according to the embedded depth and bolt length, thereby controlling the length of the steel box and avoiding waste of materials.

[0033] Four reinforcing ribs 21 are installed on the left and right sides of the splicing box 2. The inner ends of the reinforcing ribs 21 extend into the splicing box 2. By arranging the threaded ribs 22 and the reinforcing ribs 21, the two ends of the reinforcing ribs 21 and the threaded ribs 22 cross between the foundation concrete and the secondary grouting, ensuring that the grouting inside the splicing box 2 wraps the bolt part and the foundation concrete outside the splicing box 2 form a whole, ensuring the pull-out resistance of the bolts after installation, as well as the operating life and safety of the equipment under multiple loads such as vibration.
