Description

TECHNICAL FIELD

[0001] The utility model relates to construction tool technical field, concretely relates to a quick adjustment's anchor bolt pre -buried spacing device. BACKGROUND

[0002] At present, in the construction process of the combination of concrete structure and steel structure in the main body civil structure, there is the problem of poor construction precision quality and difficult control of steel structure anchor bolt pre -buried part. The construction position of steel structure anchor bolt pre -buried part is located at the frame beam column node, and the reinforcement is dense at the beam column node, the anchor bolt pre -buried part is easy to conflict with the reinforcement at the node, the anchor bolt spacing cannot be accurately controlled, and the anchor bolt pre -buried part has high perpendicularity requirement, so it is difficult to meet the design specification requirement in the construction process. In the concrete pouring construction process, the anchor bolt pre -buried part position is the pouring key part, and the pouring quality requirement is high, and the anchor bolt pre -buried part is deviated and inclined due to operation error in the vibrating operation process. The common fixing mode of anchor bolt is to bind the pre -buried fixing frame of anchor bolt at the same time of the reinforcement platform construction, then the anchor bolt is fixed on the pre -buried fixing frame to fix the anchor bolt. Such fixing mode makes the pre -buried fixing frame be pre -buried in the bottom at the same time, cannot be reused, and needs to bind the pre -buried fixing frame again each time, which is time -consuming and labor -intensive. SUMMARY

[0003] The utility model aims at solving the technical problems existing in the prior art, and particularly innovatively provides a quick adjustment's anchor bolt pre -buried spacing device, which can quickly adjust the spacing and position of anchor bolt, improve the anchor bolt installation speed, and can be reused.

[0004] In order to realize the above -mentioned purpose of the utility model, the utility model provides a quick adjustment's anchor bolt pre -buried spacing device, which comprises two spacing limit frames arranged upwards and downwards, the two limit frames are connected through the corner support rods of the corner positions on the inner side and the outer side of the frame, and at least two middle support rods are arranged in the middle of each edge, and the adjacent middle support rods on each edge are arranged on the inner side and the outer side of the frame respectively, and a plurality of through holes for the anchor bolt to pass through are arranged on the limit frame upwards and downwards.

[0005] In the above scheme, the support rods on the left and right sides of the limit frame are symmetrically arranged, and the support rods on the front and back sides are symmetrically arranged.

[0006] In the above scheme, the middle support rods are arranged between the adjacent through holes of each edge of the limit frame, the connection between the limit frames is improved, the limit effect of the anchor bolt can be guaranteed due to the strong hardness of the anchor bolt, and the upper and lower limit frames are prevented from being misaligned.

[0007] The corner support rods and the middle support rods are all made of angle steel, the inner corner support rods are flush with the inner corners of the limiting frame, and the outer corner support rods are flush with the outer corners of the limiting frame.

[0008] The straight side of the middle support rod arranged on the inner side of the frame is flush with the inner side of the limiting frame, the straight side of the middle support rod arranged on the outer side of the frame is flush with the outer side of the limiting frame, and the adjacent two middle support rods on the same side are arranged in a left-right staggered manner. The four corners of the limiting frame are surrounded by the corner support rods.

[0009] In the above scheme, the limiting frame is made of steel plate, which is simple and easy to obtain.

[0010] In summary, due to the adoption of the above technical scheme, the beneficial effects of the present application are as follows: the two limiting frames arranged in an up-down interval can limit the anchor bolts, thereby ensuring that the anchor bolts are in a vertical position, and the spacing and distribution position between the anchor bolts can also be adjusted. The corner support rods and the middle support rods can ensure the limiting effect as much as possible, thereby ensuring that the anchor bolt positioning, spacing and perpendicularity meet the specification design requirements, improving the overall anchor bolt installation quality, and ensuring the quality and construction period of the entire project. The technical scheme is only used as an adjustment tool and does not need to be pre-buried at the bottom, can be repeatedly used, does not need to be applied multiple times, saves materials and manpower. BRIEF DESCRIPTION OF DRAWINGS

[0011] The above and / or additional aspects and advantages of the present application will become apparent and more readily appreciated from the following description of the embodiments, with reference to the following drawings, in which:

[0012] Figure 1 is a top view of the present application.

[0013] Figure 2 is a front view of the present application. DETAILED DESCRIPTION

[0014] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0015] As Figure 1 , 2As shown, a quick adjustment anchor pre-burying limiting device, including upper and lower interval arrangement of limiting frame 2, two limiting frame 2 upper and lower corresponding arrangement of a plurality of through hole for anchor bolt. Limiting frame 2 corner position is arranged in the frame and frame outside corner support rod 1. Limiting frame 2 every edge of the middle part is provided with at least two middle support rod 3, and the adjacent middle support rod 3 is arranged in the frame and frame outside respectively. Limiting frame 2 left and right side edge on the support rod 1 is symmetrically distributed, and the front and back side edge on the support rod 1 is symmetrically distributed. Because the anchor bolt hardness is strong, in order to guarantee the limiting effect of anchor bolt, limiting frame 2 every edge of the adjacent through hole is provided with middle support rod 3, which improves the connection between limiting frame 2, avoids the dislocation of upper and lower limiting frame 2.
