Description

Technical Field

[0001] This utility model belongs to the field of civil engineering pre-embedded technology, and specifically relates to a co-embedded positioning device for electromechanical pipelines and civil engineering structures. Background Technology

[0002] In building construction, anchor bolts are key load-bearing components connecting electromechanical equipment to the civil structure. Their pre-embedding accuracy directly affects the stability and structural safety of subsequent electromechanical pipeline installation. Traditional anchor bolt pre-embedding construction typically uses fixed molds for positioning, such as... Figure 7 As shown, the positions of the holes on the mold for inserting anchor bolts are fixed. During construction, the anchor bolts are passed through the holes and fixed to the steel reinforcement cage according to the coordinates of the design drawings, and then concrete is poured to complete the pre-embedding.

[0003] However, in actual construction, due to unavoidable errors in civil engineering construction such as formwork deviation, rebar displacement, and concrete pouring and vibration deformation, or slight deviations in the processing dimensions of mechanical and electrical equipment, and the need for local adjustments to on-site installation coordinates due to design optimization, it is very easy for coordinate errors or deviations to occur between the actual position of the pre-embedded anchor bolts and the installation holes of the mechanical and electrical equipment. At this time, because the holes of traditional molds are fixed, the position of the anchor bolts cannot be adjusted after pre-embedding. If the deviation exceeds the allowable range, it is necessary to dismantle the poured concrete, re-install rebar, or replace the bolts. This not only causes a large waste of manpower and materials, but also delays the construction period, and may even affect the integrity and load-bearing capacity of the civil structure due to secondary structural construction.

[0004] Furthermore, with the increasing integration of modern building electromechanical systems, the requirements for coordinated construction of equipment pipelines and civil structures are becoming increasingly stringent. Traditional fixed pre-embedded molds are difficult to adapt to the dynamic adjustment needs on site, resulting in low efficiency in the connection between electromechanical installation and civil construction, which has become a prominent problem restricting project quality and progress. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a collaborative pre-embedded positioning device for electromechanical pipelines and civil engineering structures.

[0006] The technical solution adopted by this utility model to solve this technical problem is: a co-embedded positioning device for electromechanical pipelines and civil engineering structures, characterized in that it includes a fixed crossbar one, and a fixed crossbar two that are symmetrically arranged on one side of the fixed crossbar one, and both the fixed crossbar one and the fixed crossbar two have through-receiving cavities inside. Both ends of the opposite surfaces of the fixed crossbar one and the fixed crossbar two are respectively fixedly installed with a contact bottom plate and a contact top plate, and the contact top plate of the fixed crossbar one is located above the contact bottom plate of the fixed crossbar two. A screw rod that penetrates to the top of the contact top plate is fixedly installed at one end of the contact bottom plate, and a knob is threaded on the screw rod.

[0007] As a further embodiment of this utility model, both the first and second fixed crossbars are provided with an opening groove communicating with the through-cavity, and the opening groove is located at the top of the through-cavity.

[0008] As a further aspect of this utility model, a transition slope is formed between the through-hole receiving cavity and the opening groove, and the opening size of the opening groove is larger than that of the through-hole receiving cavity.

[0009] As a further embodiment of this utility model, the contact top plate has a movable through groove through which a matching screw passes and can move laterally.

[0010] As a further embodiment of this utility model, a side fixing plate is fixedly installed on one side of both the first and second fixed crossbars. The two side fixing plates are designed symmetrically to each other, and fastening holes are provided at both ends of the side fixing plates.

[0011] As a further embodiment of this utility model, the fastening mounting hole is an elongated hole.

[0012] As a further embodiment of this utility model, the outer side of the contact bottom plate is engraved with scale one, and the contact top plate and the lower contact bottom plate are engraved with scale two on the same side.

[0013] As a further embodiment of this utility model, one end of the contact top plate is engraved with a positioning mark located at one end of the scale.

[0014] This utility model has at least the following beneficial effects: 1. During use, the staff can adjust the relative position of the anchor bolts and this device according to the hole size of the electromechanical device to be installed. This design is conducive to the use of anchor bolts with different spacings, improving the usage scenarios and its flexibility.

[0015] 2. During use, the operator adjusts the distance between the first and second fixed crossbars according to the holes along the length direction. The positional changes of scales one and two provide a visual indication of the distance. After adjustment to the desired position, tighten the knob to secure it. The operator marks the overlapping portion of scales one and two using the positioning markers. Subtracting the size of the overlapping portion from the sum of scales one and two yields the distance between the two anchor bolts along the length direction. It should be noted that scales one and two are symmetrically engraved, with their measurement starting points corresponding to the first and second fixed crossbars respectively, facilitating accurate measurement of the distance between the centers of the two anchor bolts. 3. This device, through fixed crossbar one and fixed crossbar two, facilitates the installation of anchor bolts during use. By replacing existing steel plate fixing molds, it effectively reduces the risk of rework due to hole position deviations. Operators can adjust the anchor bolt spacing through repeated measurements, avoiding situations where large deviations occur after pre-embedding, requiring the demolition of poured concrete, re-installation of reinforcement bars, or replacement of bolts. Furthermore, this device is adaptable to the needs of different construction sites, eliminating the need for custom-made steel plates based on hole dimensions, thus reducing the customization waiting period.

[0019] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0020] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, and the specific implementation process is as follows: Traditional anchor bolt pre-embedding uses steel plate molds with fixed hole positions, which cannot accommodate hole position errors caused by template deviation, rebar displacement, or concrete vibration during construction, nor can it respond to on-site adjustments required for the installation coordinates of electromechanical equipment. This application solves the technical problem of anchor bolts having unadjustable positions after pre-embedding, prone to deviations, and requiring concrete demolition, by providing a pre-embedding positioning device that can be adjusted laterally and longitudinally. Specifically: Figures 1-6 As shown, a co-embedded positioning device for electromechanical pipelines and civil engineering structures is characterized by including a fixed crossbar 1, and a fixed crossbar 2 101 symmetrically arranged on one side of the fixed crossbar 1. Both the fixed crossbar 1 and the fixed crossbar 2 101 have through-receiving cavities 2 inside. Both ends of the opposite sides of the fixed crossbar 1 and the fixed crossbar 2 101 are respectively fixedly installed with a contact bottom plate 3 and a contact top plate 4. The contact top plate 4 of the fixed crossbar 1 is located above the contact bottom plate 3 of the fixed crossbar 2 101, and the contact bottom plate 3 at the other end of the fixed crossbar 1 is located below the contact top plate 4 of the fixed crossbar 2 101. A screw 5 is fixedly installed at one end of the contact bottom plate 3, extending through to the top of the contact top plate 4. A knob 502 is threaded onto the screw 5, and the knob 502 is in contact with the contact top plate 4.

[0022] In the above embodiment, by setting adjustable fixed crossbar 1 and fixed crossbar 2 101, in conjunction with the screw 5 and knob 502 structure, the anchor bolts can be flexibly adjusted in the horizontal and vertical directions, significantly improving the adaptability and accuracy of pre-embedded positioning. This structure replaces the traditional fixed mold, effectively avoiding concrete demolition and rework caused by hole position deviation, saving construction costs and time, and improving the collaborative efficiency of electromechanical installation and civil construction.

[0023] In another embodiment, if the through-hole cavity 2 is only a straight hole structure during anchor bolt installation, bolt insertion and nut installation are difficult, especially when using large-sized nuts or multiple bolts working together, resulting in low efficiency. This claim solves the problem of inconvenient and cumbersome anchor bolt installation by providing an opening slot 201 to offer a lateral installation channel. Specifically, both the first and second fixing crossbars 1 and 2 have an opening slot 201 communicating with the through-hole cavity 2. The opening slot 201 is located at the top of the through-hole cavity 2. This structure is particularly suitable for multi-bolt collaborative operations or construction scenarios with limited space. The through-hole cavity 2 is used to accommodate the anchor bolt, while the nut fastened to the anchor bolt surface is located inside the opening slot 201, or, for larger nuts, directly at the top of the first and second fixing crossbars 1 and 2.

[0024] In another embodiment, if there is a right-angle step between the opening slot 201 and the through-cavity 2, the anchor bolts are prone to jamming when inserted or adjusted, affecting the flexibility and efficiency of fine-tuning the position. This claim solves the problem of bolts moving poorly and easily jamming within the cavity by providing a transition slope 202. Specifically, a transition slope 202 is formed between the through-cavity 2 and the opening slot 201, and the opening size of the opening slot 201 is larger than that of the through-cavity 2. This structure optimizes the internal passage of the cavity, enhancing the mechanical performance and long-term reliability of the device.

[0025] In another embodiment, this embodiment solves the problem of the screw 5 being unable to move freely during lateral adjustment, thus affecting the precise control of the spacing, by setting a movable through groove 501. The contact top plate 4 has a movable through groove 501 inside, through which the screw 5 passes and can move laterally, realizing stepless adjustment of the spacing between the fixed crossbar 1 and the fixed crossbar 2 101, meeting the requirements of different anchor bolt spacings. This structure improves the flexibility and applicability of the device, reduces the use of customized molds, and lowers construction preparation costs.

[0026] In another embodiment, the pre-embedded positioning device needs to be fixed to the external support structure (such as template or steel frame). If there is no dedicated installation interface, additional welding or binding is required, resulting in low installation efficiency and poor stability. In this embodiment, side fixing plates 7 are fixedly installed on one side of both the first fixed crossbar 1 and the second fixed crossbar 101. The two side fixing plates 7 are designed symmetrically. Fastening installation holes 701 are opened at both ends of the side fixing plates 7, so that the device can be conveniently and firmly installed on the external support structure, improving the overall stability and preventing displacement during concrete pouring.

[0027] In another embodiment, the fastening mounting hole 701 is an elongated hole, which provides room for adjustment of the installation position, allowing the device to be fine-tuned according to site conditions, thus enhancing adaptability and installation flexibility. This design avoids the need for re-drilling or adjustment due to hole position deviations, improving construction error tolerance and efficiency.

[0028] In another embodiment, the outer side of the contact base plate 3 is engraved with a scale 6, and the top contact plate 4 is engraved with a scale 601 on the same side as the bottom contact plate 3. The scales 6 and 601 will facilitate the viewing of the positional relationship between the bottom contact plate 3 and the top contact plate 4.

[0029] In another embodiment, one end of the contact top plate 4 is engraved with a positioning mark 602 located at one end of the scale 601, the positioning mark 602 being located at the top of the scale 6.

[0030] The working principle of this utility model is as follows: During use, the operator can adjust the relative position of the anchor bolts and the device according to the hole size of the electromechanical component to be installed. Prioritizing the spacing between two adjacent anchor bolts in the width direction, after assembling and screwing in the anchor bolts and lower nuts, take the first or second fixing crossbar 101 and fit its opening slot 201 onto the surface of the anchor bolts. Then, screw in a new set of nuts onto the anchor bolt surface exposed at the top of the first or second fixing crossbar 101. At this time, the nuts will be in the opening slot 201. For larger nuts, they can also be placed directly on top of the first and second fixing crossbars 101. Before tightening the upper nut, the anchor bolts can be flexibly adjusted within the through-cavity 2 until the spacing between the anchor bolts in the same through-cavity 2 reaches a suitable size. Then, by tightening the upper nut, the anchor bolts and the device can be positioned and fixed. The opening size of the opening slot 201 is larger than that of the through-cavity 2, which is used to accommodate the anchor bolts, ensuring a smooth adjustment process.

[0031] Workers adjust the distance between fixed crossbar 1 and fixed crossbar 2 101 according to the hole positions along the length direction. By rotating knob 502 to release it from contact with the contact top plate 4, the relative position of the contact top plate 4 and the contact bottom plate 3 can be adjusted. Scales 6 and 601, in conjunction with the positional changes of both, provide a visual indication. After adjusting to the desired position, knob 502 is tightened to secure it. The operator uses positioning mark 602 to highlight the overlapping portion of scales 6 and 601. Subtracting the size of the overlapping portion from the sum of scales 6 and 601 yields the distance between the two anchor bolts along the length direction. It should be noted that scales 6 and 601 are symmetrically engraved, with their measurement starting points corresponding to fixed crossbar 1 and fixed crossbar 2 101 respectively, facilitating accurate measurement of the distance between the centers of the two anchor bolts. This setup facilitates anchor bolt installation and effectively reduces the risk of rework due to hole position deviations by replacing existing steel plate fixing molds.

[0032] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
