Embodiment 1

[0045] This embodiment provides a pre-embedded positioning device for anchor bolts. The pre-embedded positioning device for anchor bolts provided by this embodiment is suitable for the case where there is no vertical rib in the center of the anchor bolt group. as 1 to Figure 13 As shown, the anchor bolt embedded positioning device of the present invention includes a first positioning bracket 10 and a second positioning bracket 11, and the anchor bolt embedded positioning device of the present embodiment is composed of the first positioning bracket 10 and the second positioning bracket 11 are stacked up and down in a cross to position each anchor bolt 12 in four directions.

[0046] Preferably, the first positioning bracket 10 and the second positioning bracket 11 are well-shaped frames formed by at least two longitudinal bars 101 and at least two transverse bars 100 intersecting each other, wherein the ends of the longitudinal bars 101 protrude beyond the intersection of the ...

Embodiment 2

[0058] Embodiment 2 provides another pre-embedded positioning device for anchor bolts. The pre-embedded positioning device for anchor bolts provided in this embodiment is suitable for the case where there is a vertical bar in the center of the anchor bolt group. The difference with embodiment 1 is:

[0059] Such as Figure 14 to Figure 23 As shown, the first positioning bracket 10 and the second positioning bracket 11 also include a relief structure 103, and the relief structure 103 is used to make way for the vertical rib 13, so as to prevent the first positioning bracket 10 and the second positioning bracket 11 from being stuck on the vertical rib 13, so that the first positioning bracket 10 and the second positioning bracket 11 cannot be placed horizontally. Preferably, the relief structure 103 is a notch structure extending longitudinally outward from the center of the positioning bracket. When in use, make the relief structure 103 vertically put into the middle of the a...

Embodiment 3

[0063] This embodiment provides a construction method applicable to a kind of anchor bolt pre-embedded positioning device described in Embodiment 1 (in the case of no vertical reinforcement in the center of the anchor bolt group), including the following steps:

[0064] Step 1: Laying the bottom reinforcement bar 23 of the tower crane foundation; Figure 24 with Figure 25 shown.

[0065] Preferably, when there is no vertical rib in the center of the anchor bolt group, the structure of the support frame 22 is as follows: Figure 26 with Figure 27 as shown, Figure 26 with Figure 27 A schematic structural view of a supporting frame 22 in a preferred embodiment is shown. Preferably, the supporting frame 22 is arranged above the steel bar 23 at the foundation floor. The support frame 22 includes four-corner vertical ribs 220, oblique vertical ribs 222 and support crosspieces 221, and in this embodiment, the top positions of the four-corner vertical ribs 220 are flush with ...

Abstract

The invention provides a foundation bolt pre-embedding positioning device and a construction method thereof, relates to the technical field of electric power iron towers and street lamp poles, and solves the technical problems that a foundation bolt pre-embedding construction method is high in working difficulty, a foundation bolt fixing mode is unreliable, and the perpendicularity of a foundation bolt cannot be guaranteed. The device comprises a first positioning support and a second positioning support, the first positioning support and the second positioning support are #-shaped frames formed by intersecting at least two longitudinal rods and at least two transverse rods, and the tail ends of the longitudinal rods protrude out of the outermost intersection points of the longitudinal rods and the transverse rods and extend outwards, and limiting structures for the foundation bolts in at least two directions are formed at the intersection points located on the outermost sides of the positioning supports, and the first positioning support and the second positioning support are stacked up and down in a crossed mode so as to position each foundation bolt in four directions. After positioning is conducted through the first positioning support and the second positioning support, the position size of the whole set of foundation bolts is accurate, and the overall stability is good.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pre-embedded positioning device for anchor bolts and a construction method thereof. Background technique [0002] Before pouring the tower crane foundation, it is necessary to pre-embed the foundation bolts of the tower crane. At present, after laying the foundation steel bars, the foundation bolts are installed on the foundation chassis and put into the foundation pit, but the foundation chassis of the tower crane is heavy. , The construction site must use special hoisting equipment to hoist the foundation chassis and anchor bolts into the foundation pit. In addition, it is necessary to set up a stable support point under the foundation chassis to ensure the level of the foundation chassis. At the same time, it is necessary to ensure that the anchor bolts must be embedded vertically to the ground. shift. The usual practice is to make the anchor bolts and the in...
