Embodiment 1

[0047] The device of the foundation suspension embedded bolt of the present embodiment, as figure 1 As shown, it includes hanging beam 1, bolt rod 5, nut, primary hoarding board 8 and positioning correction board 4, wherein: as figure 2 and 3 As shown, the first-level hoarding 8 is a square pool-like structure surrounded by flat plates, with a specification of 60mm*60mm. There are two hanging beams 1, which are long wooden boards with a thickness of 35mm, a width of 120mm, and a length of 1200mm. Parallel and symmetrical state is placed in the middle of the upper surface of the primary coaming board 8. The positioning correction plate 4 is a square plate-shaped structure with a specification of 50mm*40mm. The positioning of the connecting bolt rod 5 is provided on the hanging beam 1 and the positioning correction plate 4. Hole 7, diameter is 5mm; Nut comprises upper nut 2 and lower nut 3; The upper end of bolt rod 5 is provided with screw thread, and diameter is 3mm, passes ...

Embodiment 2

[0058] The basic structure of the device for suspending pre-embedded bolts in this embodiment is the same as in Embodiment 1, and the improvement is that there are 6 bolt rods 5, and the corresponding positioning holes 7 of the suspension beam 1 and the positioning correction plate 4 are also 6 , cooperating with the arrangement, the six bolt rods 5 work together, and the construction accuracy is higher; the bottom of the bolt rod 5 is fixedly connected with the bracket 6, and the bottom plate 61 of the bracket 6 is fixedly connected with the bottom end of the bolt rod 5, so as to improve the bolt rod 5 in the concrete The stability of the bolt rod 5 and the bottom plate 61 is also fixedly connected with tapered and evenly distributed reinforcing ribs 62 to improve the stability of the connection between the bracket 6 and the bolt rod 5; the bottom end of the primary coaming plate 8 is connected with an area larger The secondary enclosure 9 of the primary enclosure 8, the prima...

Embodiment 3

[0061] The basic steps of the construction method of a foundation suspension pre-embedded bolt device in this embodiment are the same as in Embodiment 2, the difference is that in step B, at the four corners of the coaming boards at all levels, the sides of the two coaming boards A reinforcing plate is fixed between the plates to improve the stability of the connection of the side plates of the hoarding.

Abstract

The invention discloses a device and a construction method for foundation suspension pre-embedded bolts, belonging to the technical field of building foundation fixing. The device for suspending pre-embedded bolts on the basis of the present invention includes a hanging beam, a bolt rod, a nut, a first-level enclosure and a positioning correction plate. The first-level enclosure is a square pool-shaped structure surrounded by a flat plate. There are 2, which are placed in the middle of the upper surface of the primary hoarding in a parallel and symmetrical state. The positioning correction plate is a square plate-like structure. Nut and lower nut; the upper end of the bolt rod is provided with threads, which pass through the positioning holes of the hanging beam and the positioning correction plate in turn, and are fixed at the position between the hanging beam and the positioning correction plate by the upper nut and the lower nut, The upper nut is fixed on the lower surface of the positioning correction plate, and the lower nut is fixed on the upper surface of the hanging beam. The invention achieves the purposes of simple manufacturing process, convenient construction, less influence of related processes, convenient inspection and adjustment, high construction precision and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of building foundation fixing, in particular to a device and construction method for foundation suspension pre-embedded bolts. Background technique [0002] The installation and reinforcement of existing pre-embedded bolts usually adopt spot welding of pre-embedded bolts to the foundation steel mesh, or often use steel bars and section steel to weld a tripod support in the foundation concrete for reinforcement, but it is difficult to position and set out the pre-embedded bolts one by one , the amount of welding is large and the screw is easy to burn, which wastes steel, and it is easy to cause the bolt to deviate when pouring concrete. [0003] At present, there are commonly used construction methods for embedded bolts in steel column foundations, and the usual methods are as follows: [0004] 1) First, fix multiple bolts uniformly on the positioning orifice plate with the holes opened. [0005] 2) Weld wi...
