AI Technical Summary
In existing technologies, it is difficult to control the construction accuracy of large embedded parts in the interior wall panels of building structures. In particular, the embedded accuracy of the support arm embedded parts in the proton therapy room cannot reach within ±1mm, and traditional electric welding fixation may cause thermal deformation, affecting stability.
The height, levelness, and planar position of large embedded parts are adjusted by using a support frame and leveling nuts in conjunction with jacks. Combined with self-compacting concrete for fixing, thermal stress deformation caused by electric welding is avoided, and the pre-embedding accuracy is ensured through mechanical means.
It enables precise pre-embedding of large embedded parts within the wall panel, meeting design and construction accuracy requirements, ensuring the stability of embedded parts and the normal operation of equipment in the later stages, and simplifying construction operations.

Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a construction method for adjusting large embedded parts to achieve the design and construction accuracy. Background Technology
[0002] In building structures, embedded parts serve to provide a rigid connection point for the safe and reliable transfer of loads from one structural system to another. Traditional embedded part construction techniques typically involve welding anchor bars to the reinforcing bars within the concrete structure. Once welded in place, if the reinforcing bar cage shifts, the embedded part as a whole will shift, thus reducing its accuracy. Furthermore, this method is generally suitable for small embedded parts.
[0003] During the construction of the proton therapy room, two support arm embedded parts need to be pre-embedded. As part of the equipment itself, these support arm embedded parts need to be pre-embedded into the wall panels of the building structure. Using traditional construction methods to pre-embed these support arm embedded parts presents two difficulties: first, welding is not possible, which would cause the embedded parts to deform due to heat, affecting their overall stability and subsequent use; second, it is impossible to use lifting equipment to adjust the position of the embedded support arm embedded parts within the wall panels of the building structure, making it difficult to control the pre-embedding accuracy within ±1mm, thus failing to meet the design and construction accuracy requirements.
[0004] The aforementioned construction difficulties also exist for the pre-embedding of other large embedded parts in structural components such as walls and panels in building structures. This is especially true when the precision requirements for pre-embedding large embedded parts are far higher than those in ordinary industrial and civil buildings, significantly increasing the construction difficulty. Therefore, there is a need for a construction method to adjust large embedded parts to achieve the designed construction precision, which can solve the problem of difficult pre-embedding of large embedded parts with high precision requirements in the internal walls and panels of building structures in existing technologies. Summary of the Invention
[0005] The purpose of this invention is to provide a construction method for adjusting large embedded parts to achieve the design and construction accuracy, which can solve the problem of the difficulty in pre-embedding large embedded parts with high pre-embedding accuracy requirements in the inner wall panels of building structures in the prior art.
[0006] To achieve the above objectives, the technical solution of the present invention is as follows:
[0007] A construction method for adjusting large embedded parts to achieve design and construction accuracy, characterized by comprising the following steps:
[0008] Step 1: Erect a support frame for the embedded part below the pre-embedded location of the large embedded part. The support frame is located inside the wall panel.
[0009] Step 2: Pour the first section of concrete for the panel wall. The finished surface of the first section of concrete should be lower than the top of the support frame so that large embedded parts can be hoisted onto the support frame.
[0010] Step 3: Hoist the large embedded parts onto the support frame and adjust their height and level;
[0011] Step 4: Adjust the planar position of the large embedded parts;
[0012] Step 5: Pour the second section of concrete for the panel wall so that the bottom of the large embedded parts can be anchored in the second section of concrete.
[0013] Step 6: Pour the third section of concrete for the panel wall to form the panel wall, allowing large embedded parts to be precisely pre-embedded in the panel wall.
[0014] The support frame includes columns, crossbeams, embedded plates, and longitudinal beams. The embedded plates are embedded in the foundation slab below the large embedded parts. The lower ends of the columns are fixedly installed on the embedded plates. Several columns are spaced apart and arranged inside the area through which the reserved vertical reinforcing bars pass in the wall panel. The crossbeams are arranged parallel to the length direction of the reserved vertical reinforcing bars and horizontally erected on the upper ends of the columns. The longitudinal beams are arranged perpendicular to the length direction of the reserved vertical reinforcing bars and horizontally erected on the upper ends of two oppositely arranged columns.
[0015] Limiting posts are installed at the ends of the crossbeams and longitudinal beams located at the four corners of the support frame, with the limiting posts extending vertically upwards; the ends of the longitudinal beams located at the four corners of the support frame extend to the outside of the area through which the reserved vertical reinforcing bars pass.
[0016] The distance between the finished concrete pouring surface and the bottom surface of the crossbeam of the support frame is mm.
[0017] The three steps mentioned above include the following sub-steps:
[0018] Step 3.1: After the first section of concrete has initially set, install leveling nuts on the top of the crossbeams and longitudinal beams of the support frame. Several leveling nuts are arranged at intervals along the length of the crossbeams and longitudinal beams.
[0019] Step 3.2: Hoist the large embedded parts and place them on the leveling nuts, with the large embedded parts located inside each limiting post;
[0020] Step 3.3: Adjust the height and level of the large embedded parts by rotating the thread of the leveling nut.
[0021] The leveling nut includes an adjusting nut and an adjusting bolt. The adjusting nut is installed on the top surface of the crossbeam and the longitudinal beam. The lower end of the adjusting bolt is screwed into the adjusting nut. The upper end of the adjusting bolt forms a flat surface for placing large embedded parts.
[0022] Step 4 includes the following sub-steps:
[0023] Step 4.1: Install jacks horizontally between the limiting column of the support frame and the side wall of the large embedded part, with several jacks spaced apart around the circumference of the large embedded part.
[0024] Step 4.2: Adjust the planar position of the large embedded parts using several jacks based on the isocenter points of the building structure;
[0025] Step 4.3: Secure the large embedded part in the gap between the limiting post and the side wall of the large embedded part by inserting wooden wedges. Several wooden wedges are arranged at intervals along the circumference of the large embedded part to fix its planar position.
[0026] Step 4.4: Remove several jacks.
[0027] Step 5 includes the following sub-steps:
[0028] Step 5.1: Install several anchor bolts at the bottom of the large embedded part, and pour the second section of concrete to the bottom surface of the large embedded part so that the anchor bolts at the bottom of the large embedded part are anchored in the second section of concrete.
[0029] Step 5.2: After the concrete in the second section of step reaches the design strength, remove the excess parts of the wooden wedges and support frame that were inserted in step 1.
[0030] The concrete strength grade of the second section is the same as that of the slab wall, and the concrete used in the second section is self-compacting concrete.
[0031] In step 6, when pouring the third section of concrete, avoid pouring the concrete directly onto the large embedded part, and pour the concrete symmetrically on both sides of the large embedded part.
[0032] Compared with the prior art, the present invention has the following beneficial effects:
[0033] 1. This invention provides support for large embedded parts through a support frame equipped with leveling nuts. The height and levelness of the large embedded parts can be adjusted by rotating the threads. At the same time, the horizontal position of the large embedded parts is adjusted by a jack horizontally set between the large embedded parts and the limiting column. This ensures the accuracy of the pre-embedded position of the large embedded parts in the wall panel. The correction method is convenient and can meet the pre-embedded accuracy requirements of large embedded parts. It avoids problems such as elevation difference, plane position difference, horizontal flatness, and relative position error between embedded parts in the pre-embedded position of large embedded parts. This ensures the normal operation of the equipment connected to the large embedded parts later. It solves the problem that the pre-embedded accuracy of large embedded parts in the wall panel cannot be directly adjusted by lifting equipment. It is especially suitable for the pre-embedded construction of large embedded parts such as the support arm embedded parts of proton therapy machine rooms in the wall panel and other components of building structures.
[0034] 2. This invention adopts a mechanical + self-compacting concrete fixing method, which avoids the problem of thermal stress deformation caused by traditional electric welding connection of large embedded parts, ensuring the overall stability of large embedded parts and their subsequent operational safety. Moreover, the operation is relatively simple and helps to speed up the construction progress of the proton room wall. Attached Figure Description

Detailed Implementation
[0046] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a construction method for adjusting large embedded parts to achieve design and construction accuracy according to the present invention. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0047] A construction method for adjusting large embedded parts to achieve design and construction accuracy includes the following steps:
[0048] Please see the appendix Figure 1 To be continued Figure 3 Step 1: Erect a support frame for the embedded part below the pre-embedded position of the large embedded part 5. The support frame is located inside the wall panel.
[0049] The support frame includes columns 3, crossbeams 3, embedded plates 1, and longitudinal beams 4. The embedded plates 1 are embedded in the foundation plate below the large embedded parts 5. The lower ends of the columns 2 are fixedly installed on the embedded plates 1. Several columns 3 are spaced apart and arranged inside the reserved vertical steel reinforcement passage area 7 of the wall. The crossbeams 3 are arranged parallel to the length direction of the reserved vertical steel reinforcement passage area 7 and are horizontally erected on the upper end of the columns 3. The longitudinal beams 4 are arranged perpendicular to the length direction of the reserved vertical steel reinforcement passage area 7 and are horizontally erected on the upper end of the two opposite columns 2.
[0050] During the construction of the foundation slab, embedded plates 1 are pre-installed on the foundation slab below the large embedded parts 5 according to their pre-embedded positions. These plates are used for the vertical fixing and installation of the columns 2. The number and arrangement of the embedded plates 1 can be adjusted according to the actual support requirements. Since the support frame is located inside the wall slab, it is necessary to avoid the reserved vertical reinforcement bars inside the wall slab. The embedded plates 1 are arranged inside the area 7 through which the reserved vertical reinforcement bars pass. The erection of the support frame can be carried out simultaneously with the construction of the reserved vertical reinforcement bars in the wall slab.
[0051] The columns 2, horizontal beams 3, and longitudinal beams 4 can be fixedly connected by welding, bolting, or other methods to form a rectangular frame support structure, which provides support for the construction of the large embedded parts 5. Preferably, the columns 2, horizontal beams 3, and longitudinal beams 4 can all be made of 18# I-beams, and the lengths of the columns 2, horizontal beams 3, and longitudinal beams 4 can be selected according to the size of the large embedded parts 5 and the thickness of the wall panel.
[0052] Large embedded parts 5 can be large embedded parts with large volume and heavy weight, such as the support arm embedded parts of the proton therapy machine room.
[0053] Limiting posts 6 are installed at the ends of the crossbeams 3 and longitudinal beams 4 located at the four corners of the support frame. The limiting posts 6 extend vertically upwards. The ends of the longitudinal beams 4 located at the four corners of the support frame extend to the outside of the reserved vertical steel bar passage area 7.
[0054] Preferably, the limiting post 6 can be made of a 50×50×5 rectangular tube. The limiting post 6 can be vertically installed at the ends of the crossbeam 3 and the longitudinal beam 4 by welding. The eight limiting posts 6 are located on the outer periphery of the large embedded part 5 to provide limiting for the large embedded part 5 and to facilitate subsequent horizontal position adjustment.
[0055] Please see the appendix Figure 4 Step 2: Pour the first section of concrete 71 of the wall panel. The finished concrete surface 711 of the first section of concrete 71 is lower than the top of the support frame, so that the large embedded part 5 can be hoisted onto the support frame.
[0056] Preferably, the distance between the finished concrete pouring surface 711 and the bottom surface of the crossbeam 3 of the support frame is 420mm, and the pouring height of the finished concrete pouring surface 1 can also be adjusted according to actual construction needs.
[0057] The first section of concrete 71 was poured using conventional concrete construction techniques, which will not be described in detail here.
[0058] Please see the appendix Figure 5 Step 3: Hoist the large embedded part 5 onto the support frame and adjust its height and level.
[0059] Step 3 includes the following sub-steps:
[0060] Step 3.1: After the first section of concrete 71 has initially set, install leveling nuts 8 on the top of the crossbeams 3 and longitudinal beams 4 of the support frame. Several leveling nuts 8 are arranged at intervals along the length of the crossbeams 3 and longitudinal beams 4.
[0061] Please see the appendix Figure 6 Preferably, the leveling nut 8 may include an adjusting nut 81 and an adjusting bolt 82. The adjusting nut 81 is welded and installed on the top surface of the crossbeam 3 and the longitudinal beam 4. The lower end of the adjusting bolt 82 is screwed into the adjusting nut 81. The upper end of the adjusting bolt 82 forms a plane for the large embedded part 5 to rest on.
[0062] By rotating the adjusting bolt 82 relative to the thread of the adjusting nut 81, the rotation of the adjusting bolt 82 can be converted into the axial linear movement of the adjusting bolt 82, thereby adjusting the height of the upper plane of the adjusting bolt 82, and then adjusting the level of the large embedded part 5 after it is placed on the leveling nut 8.
[0063] The specifications and quantity of the leveling nut 8 can be adjusted according to the load requirements. Alternatively, other components with leveling functions in the existing technology can be used to replace the leveling nut 8, which will not be elaborated here.
[0064] Step 3.2: Use existing lifting equipment to hoist the large embedded part 5, place the large embedded part 5 on the leveling nut 8, and position the large embedded part 5 inside each limiting post 6.
[0065] Step 3.3: Adjust the height and level of the large embedded part 5 by rotating the thread of the leveling nut 8.
[0066] The adjustment of the thread rotation of the leveling nut 8 is a conventional adjustment method in this field, and will not be described in detail here.
[0067] Please see the appendix Figure 7 and attached Figure 8 Step 4: Adjust the planar position of the large embedded part 5.
[0068] Step 4 includes the following sub-steps:
[0069] Step 4.1: Install jacks 9 horizontally between the limiting column 6 of the support frame and the side wall of the large embedded part 5, with several jacks 9 arranged at intervals along the circumference of the large embedded part.
[0070] Step 4.2: Based on the isocenter point of the building structure (e.g., proton therapy room), adjust the planar position of the large embedded part 5 using several jacks 9 to ensure that the planar position of the large embedded part 5 is consistent with the design position.
[0071] By extending the jack 9 outward or retracting it inward, the large embedded part 5 can be pushed to move laterally and / or longitudinally on several leveling nuts 8, thereby adjusting the horizontal position of the large embedded part 5 to meet the requirements of pre-embedding accuracy.
[0072] The adjustment operation of the jack 9 is simple and precise. The jack 9 is a commonly used jacking adjustment method in this field, and will not be described in detail here.
[0073] Step 4.3: Wooden wedges 10 are inserted into the gap between the limiting post 6 and the side wall of the large embedded part 5. Several wooden wedges 10 are arranged at intervals along the circumference of the large embedded part 5 to fix the planar position of the large embedded part 5.
[0074] The number and size of the wooden wedges 10 can be adjusted according to actual usage needs. The wooden wedges 10 are used to fill the gap between the limiting post 6 and the side wall of the large embedded part 5, and are used to temporarily fix the plane position of the large embedded part 5 in the wall panel.
[0075] Step 4.4: Remove several jacks 9.
[0076] Please see the appendix Figure 9 Step 5: Pour the second section of concrete 72 into the wall panel so that the bottom of the large embedded part 5 can be anchored in the second section of concrete 72.
[0077] Step 5 includes the following sub-steps:
[0078] Step 5.1: Install several anchor bolts 51 at the bottom of the large embedded part 5, and pour the second section of concrete 72 to the bottom surface of the large embedded part 5 so that the anchor bolts 51 at the bottom of the large embedded part 5 are anchored in the second section of concrete 72.
[0079] The specifications and quantity of anchor bolts 51 can be adjusted according to actual anchoring requirements. With the temporary fixation of wooden wedges 10, the large embedded part 5 will not be displaced when the second section of concrete 72 is poured. At the same time, the bottom of the large embedded part 5 is fixed inside the wall by anchoring it in the second section of concrete 72 through anchor bolts 51.
[0080] Preferably, the concrete strength grade of the second concrete section 72 is the same as that of the wall panel, and the concrete of the second concrete section 72 is self-compacting concrete to avoid displacement of the large embedded part 5 caused by vibrating the concrete.
[0081] Step 5.2: After the strength of the second section of concrete 72 reaches the design value, remove the wooden wedges 10 and the excess parts of the support frame that were inserted in step 4.3.
[0082] Since the ends of the longitudinal beams 4 at the four corners of the support frame extend to the outside of the reserved vertical steel bar passage area 7, it is necessary to remove the part of the longitudinal beams 4 that extends out of the reserved vertical steel bar passage area 7, and at the same time remove the eight limiting columns 6.
[0083] Please see the appendix Figure 9 Step 6: Pour the third section of concrete 73 into the slab wall to form the slab wall, so that the large embedded part 5 can be accurately embedded in the slab wall.
[0084] With the anchoring effect of several anchor bolts 51 in the second section of concrete 72, the pouring of the third end concrete 73 will not cause the large embedded part 5 to shift, thus ensuring the accurate pre-embedded position of the large embedded part 5 in the wall after the wall is poured.
[0085] In step 6, when pouring the third section of concrete 73, care should be taken to avoid pouring the concrete directly onto the large embedded part 5, and the concrete should be poured symmetrically on both the left and right sides of the large embedded part 5.
[0086] The third section of concrete 73 was poured using conventional concrete construction techniques, which will not be described in detail here.
[0087] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
