Description

Technical Field

[0001] The utility model is applicable to the field of adjustment construction of steel plate embedded parts, in particular to the positioning construction structure of embedded parts of equipment foundation. Background Art

[0002] With the rapid advancement of urbanization, a large number of municipal projects such as water supply, sewage treatment and domestic waste treatment need to be built. The installation and management of engineering equipment in municipal projects have a vital impact on the quality of the entire project. As the main connector of the main structure, embedded parts can firmly connect the installed equipment with reinforced concrete. They are important nodes for transmitting structural loads. Generally, they are embedded in the top surface of the raft, the top and side surfaces of the beams, and the top surface of the columns according to the design drawings. At present, the embedded parts of the foundation for installing equipment are large in size, wide in thickness, and have high precision requirements. Because the embedded parts panels are of different sizes and the anchor steel bars they require are thick and numerous, the installation of the embedded parts of the equipment foundation is very troublesome, and the embedded precision is difficult to meet the requirements, which cannot achieve the expected effect, and sometimes causes the problem of bearing rework.

[0003] The Chinese utility model patent (application number: 202320456494.9) discloses an embedded part positioning auxiliary device, including a support frame, an embedded steel plate and an embedded pipe. A first bolt is embedded and connected to one side of the inner part of the embedded steel plate, and the bottom of the first bolt is nested and connected to the embedded pipe. A second bolt is embedded and connected to one side of the inner part of the embedded steel plate, and the bottom of the second bolt is nested and connected to the embedded bolt. A level is embedded and connected to one side of the inner part of the embedded steel plate, and a scale line is embedded and connected to the inner part of the level. A slide groove is embedded and connected to the inner part of the support frame, and an adjustment bolt is embedded and connected to the inner part of the slide groove. The adjustment bolt improves the movement stability of the fixed plate. By setting an auxiliary mechanism, the work efficiency is improved, and the overall strength of the embedded structure is improved. The bearing facilitates the rotation of the threaded rod and changes the length in the sleeve. By setting a positioning mechanism, embedded steel plates of different sizes can be assisted in positioning, thereby improving the flexibility and functionality of the device body.

[0004] The above-mentioned prior art positions the embedded parts before pouring the slow-setting soil.

DETAILED DESCRIPTION

[0022] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0023] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0024] The embedded parts 1 used for positioning are arranged on the column-penetrating steel bars in the column. Frame columns are arranged around the column. They are positioned according to the control lines on the wall and the elevation control lines of the wall surface, and are installed, positioned and poured with concrete. After the concrete is vibrated and before the concrete begins to set, the embedded steel plates of the embedded parts 1 are checked, and the equipment foundation embedded parts positioning construction structure of the utility model is used to adjust the elevation and horizontal deviations.

[0025] like Figures 1 to 6 As shown, the equipment foundation embedded component positioning construction structure according to one embodiment of the utility model includes an elevation positioning mechanism 2 and a horizontal positioning mechanism 3, which are respectively used to accurately adjust the elevation and level of the embedded components.

[0026] The elevation positioning mechanism 2 is arranged above the embedded steel plate of the embedded part 1, and includes a positioning mechanism bottom plate 201, a drawing wire rope 212 and a drawing bolt 204. The positioning mechanism bottom plate 201 is a square structure with a thickness of 8 mm and a size of 500 mm*500 mm, and a circular opening with a diameter of 180 mm is arranged in the middle. The circular opening can be used to place a measuring device such as a level on the embedded steel plate of the embedded part 1 to measure the deviation of the elevation and level.

[0027] Fixing nuts 205 are fixedly arranged at the four corners of the upper surface of the positioning mechanism bottom plate 201, and fixing bolts 202 are threadedly connected in the fixing nuts 205. The fixing bolts 202 pass through the positioning mechanism bottom plate 201, and the protruding length of the fixing bolts 202 below the positioning mechanism bottom plate 201 can be adjusted by rotating the fixing bolts 202. The bottom of the fixing bolts 202 abuts against the angle steel 211, which is arranged parallel to the positioning mechanism bottom plate 201 and is at an angle of 45° relative to the side of the positioning mechanism bottom plate 201, and can be set on the wooden square in the horizontal direction of the frame column of the embedded part, so as to support the positioning mechanism bottom plate 201. A steel wire rope 206 is sleeved on the fixing bolt 202, and the end of the steel wire rope 206 is fixed to one end of the tensioning fastening bolt 208, and the other end of the tensioning fastening bolt 208 is fixed to the steel hook 210. The steel hook 210 can be hooked on the reinforcing steel pipe in the horizontal direction of the frame column of the embedded steel plate, thereby achieving the fixing of the positioning mechanism bottom plate 201. Specifically, as Figure 1 As shown, the end of the steel wire rope 206 is fixed to one end of the tensioning fastening bolt 208 through a first fastening buckle 207 , and the other end of the tensioning fastening bolt 208 is fixed to the steel hook 210 through a second fastening buckle 209 .

[0028] The tensioning fastening bolt 208 is an existing tensioning bolt structure, specifically comprising two bolts and an elliptical ring, with two threaded holes at both ends of the elliptical ring for threaded connection with the bolts. The two bolts are respectively connected to a wire rope or other fixed structure, and by rotating the elliptical ring, the two bolts can rotate relative to the elliptical ring through the threaded structure, thereby allowing the two bolts to move closer to or away from each other, thereby achieving a tensioning operation.

[0029] By rotating the tensioning fastening bolt 208 to put the wire rope 206 in a taut state and rotating the fixing bolt 202 to make the angle steel 211 closely contact the wooden planks on the horizontal direction of the frame column, the positioning mechanism base plate 201 can be fixed above the embedded steel plate 1 so that no displacement occurs when the elevation is adjusted.

[0030] Four pulling steel wires 212 are fixed to the bottom of the positioning mechanism bottom plate 201. The end of each pulling steel wire 212 is fixed to one end of a tension bolt, and a pulling steel hook is fixed to the other end of the tension bolt. The pulling steel hook can be hooked on the edge of the embedded steel plate. The distance between the positioning mechanism bottom plate 201 and the embedded steel plate is shortened by rotating the tension bolt, and then the embedded steel plate is pulled upward when the embedded steel plate sinks. The structure of the tension bolt is the same as that of the tension fastening bolt 208, and will not be described in detail again. Figure 1 As shown, four drawing wire ropes 212 are arranged in groups of two on both sides of the positioning mechanism bottom plate 201.

[0031] Three pull nuts 203 are fixedly arranged at equal intervals around the circular opening of the positioning mechanism bottom plate 201. The pull nuts 203 are threadedly connected with pull bolts 204, which pass through the positioning mechanism bottom plate 201 and contact the upper surface of the embedded steel plate at the lower end. By screwing the pull bolts 204, the distance between the positioning mechanism bottom plate 201 and the embedded steel plate can be increased, and then the embedded steel plate can be pressed downward when the embedded steel plate floats.

[0032] The above-mentioned pulling up and pressing down operations cannot be performed at the same time. It is necessary to check the horizontality and elevation of the embedded steel plate according to the level ruler and level meter, and perform operations and adjustments according to the actual situation to meet the design and specification requirements.

[0033] The horizontal positioning mechanism 3 includes bolts 306 passing through the wooden square of the frame column of the embedded part 1. The number of bolts 306 is 4, which are respectively arranged at four positions around the embedded part 1, that is, 2 bolts in the horizontal direction of the frame column and 2 bolts in the longitudinal direction. The positions of the bolts 306 correspond to the positions of the anchoring steel bars of the embedded part 1. Figure 6Only two bolts 306 in the transverse direction are shown, and two bolts 306 are also provided in the longitudinal direction. The bolts 306 are connected to the bolt head 304 through the steel bar head 305 at the inner end of the frame column, and the bolt head 304 is in contact with the anchor steel bar of the embedded part 1. The bolts 306 are connected to the outer thread of the frame column with a mountain-shaped clamp or a dovetail clamp 303. By rotating the mountain-shaped clamp or the dovetail clamp 303, the bolts 306 can be controlled to move in the transverse or longitudinal direction. After the embedded part 1 is placed, the mountain-shaped clamp or the dovetail clamp 303 of the bolts 306 in four directions is rotated to fix the position, and after the concrete is vibrated and before the concrete is initially set, the embedded part 1 is pushed to move in the transverse and longitudinal directions, thereby solving the problem of inaccurate horizontal positioning of the embedded part.

[0034] The elevation control of the utility model adopts a shaping tool to be fixed on the upper part of the beam and column, and the elevation and surface level of the embedded steel plate are accurately adjusted by pulling and pressing the embedded steel plate with bolts; the horizontal control adopts the original tension bolts to add bolt heads, and the bolt heads are vertically overlapped with the anchor steel bars of the embedded parts, and the bolt heads generate horizontal tension on the anchor steel bars of the embedded parts by adjusting the tightness of the bolts on the tension template, causing the embedded parts to be displaced in the horizontal and vertical directions; through elevation control and horizontal displacement control, the embedded parts are fine-tuned, and the position accuracy in the horizontal and vertical directions is greatly improved.

[0035] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
