Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a tool-type support structure and a construction method for reinforcing an ultra-thick inner wall. Background Art

[0002] With the development of society, people are paying more and more attention to their health and the demand for medical services is getting higher and higher, which further puts forward higher functional requirements for medical buildings. Among them, the linear accelerator is a particle accelerator device used for radiotherapy of tumors in biomedicine. Due to its particularity, in order to prevent the leakage of rays when the linear accelerator is working, the building is required to meet the radiation protection regulations. Generally, the thickness of the inner wall of the linear accelerator area will exceed 1m, or even several meters thick, and the inner wall has many reinforcements and complex pipelines. The construction of such ultra-thick inner walls needs to be improved in at least the following aspects:

[0003] 1. How to reinforce the side formwork of this super-thick inner wall to avoid the phenomenon of mold expansion during the actual pouring process;

[0004] Second, the conventional tension screws are used to fix the side formwork. The tension screws are densely distributed, usually 500mm apart in the vertical and horizontal directions. However, for the inner wall with densely arranged pipelines, how to avoid this is the key point of improvement;

[0005] 3. Radiation-resistant walls have very high requirements on the compactness of the formed walls. Practical tension screws are used to fix the side molds, which can easily form a penetrating gap in the cavity.

[0006] In order to solve the above problems, the inventor provides a tool-type support structure and a construction method for reinforcing an ultra-thick inner wall. Summary of the invention

[0007] In order to improve the casting quality of ultra-thick inner walls, the present application provides a tool-type support structure and a construction method for reinforcing ultra-thick inner walls.

[0008] On the one hand, the present application provides a tool-type support structure for reinforcing an ultra-thick inner wall, which adopts the following technical solution:

[0009] A tool-type support structure for reinforcing an ultra-thick inner wall, comprising an assembled support frame, a side form system and an anti-lateral displacement system, wherein the side form system is arranged around the contour of a wall to be cast to form a casting cavity, the assembled support frame is arranged on a side of the side form system away from the casting cavity to support the side form system, and the anti-lateral displacement system is arranged between the assembled support frame and the construction ground to limit the movement of the assembled support frame.

[0010] By adopting the above technical solution, the side formwork system around the wall to be cast forms a casting cavity for wall casting, and an assembled support frame is set to support the side formwork system instead of the traditional tension screw fixed formwork structure, which effectively avoids wall perforation and interference with internal wall wiring. The assembled support frame replaces the traditional tension screw support fixed side formwork system, which can effectively avoid the interference with wiring and wall perforation caused by the tension screw penetrating the wall; an anti-lateral shift system is set to specially reinforce the connection between the assembled support frame and the construction ground. When the wall thickness is too large and the assembled support frame is subjected to a large force, the assembled support frame is prevented from shifting horizontally, thereby ensuring the stable position of the side formwork system, the stable wall contour, and the quality of the wall.

[0011] Optionally, the anti-lateral displacement system includes a vertically arranged support rod and an obliquely arranged anti-lateral displacement rod, wherein the upper end of the anti-lateral displacement rod is fixed to the support rod, and the lower end of the anti-lateral displacement rod is inclined toward a side away from the side formwork system; the lower end of the anti-lateral displacement rod is pre-buried in the construction ground, and the upper end of the support rod is fixed to an assembled support frame; the lower ends of the anti-lateral displacement rod and the support rod are both fixed with anchor plates, and the anchor plates are pre-buried in the construction ground.

[0012] By adopting the above technical scheme, the support rod fixes the assembled support frame on the construction ground, and the support rod itself can withstand a large vertical force; the anti-lateral shift rod arranged on the side of the support rod away from the side formwork system can bear a large horizontal force, and the anti-lateral shift rod supports the support rod to prevent the support rod from deformation while preventing the assembled support frame and the side formwork system from lateral shift, thereby ensuring that the wall structure does not change; the anchoring steel plate can increase the force-bearing area between the lower ends of the support rod and the anti-lateral shift rod and the construction ground, thereby preventing the support rod and the anti-lateral shift rod from moving as a whole.

[0013] Optionally, the assembled support frame includes vertically arranged load-bearing rods and multiple force-transmitting rods, the load-bearing rods and the force-transmitting rods are assembled to form a triangular or trapezoidal support frame, the force-transmitting rods and the load-bearing rods, and the force-transmitting rods and the force-transmitting rods are connected by bolt fasteners, and the load-bearing rods abut and support the side formwork system.

[0014] By adopting the above technical scheme, the support frame with a triangular or trapezoidal structure can better concentrate the force of the load-bearing rods to the bottom of the support frame through the force transmission rods, that is, the load is concentrated on the anti-lateral displacement system below the assembled support frame, and the anti-lateral displacement system can effectively play a force-bearing role; the assembled support frame is assembled from multiple rods by bolt fasteners, and can be disassembled and transported during transportation. It is convenient to transport and assemble, which is conducive to the reuse of the assembled support frame.

[0015] Optionally, two anti-lateral displacement systems are arranged under the assembled support frame, and the two anti-lateral displacement systems are respectively a first anti-lateral displacement system and a second anti-lateral displacement system. The first anti-lateral displacement system is arranged at one end of the assembled support frame close to the side mold system, and the second anti-lateral displacement system is arranged at one end of the assembled support frame away from the side mold system.

[0016] By adopting the above technical solution, the anti-lateral shift function of the anti-lateral shift system is optimized. The first anti-lateral shift system is arranged on the side of the assembled support frame close to the side form system, directly supporting the lower area of ​​the side form system, which can effectively prevent the lower part of the side form system from lateral shifting; the second anti-lateral shift system is arranged on the side of the assembled support frame away from the side form system, and the force on the upper part of the side form system is mainly concentrated on the end of the assembled support frame away from the side form system after being transmitted through the assembled support frame. The second anti-lateral shift system can effectively bear the load on the upper part of the side form system, thereby effectively preventing the upper part of the side form system from moving.

[0017] Optionally, the support rod is a screw rod, the support rod passes through the lowest horizontal rod body of the assembled support frame, two pairs of fastening nuts are screwed on the support rod and the two pairs of fastening nuts are respectively located on both sides of the horizontal rod body, and a positioning pad is provided between each pair of the fastening nuts and the horizontal rod body;

[0018] The second anti-lateral displacement system also includes a U-shaped sleeve, which is buckled at the end of the horizontal rod body away from the side mold system. The U-shaped sleeve is clamped and fixed between two positioning pads and abuts against the corresponding support rod. The upper end of the anti-lateral displacement rod in the second anti-lateral displacement system has the same height as the U-shaped sleeve.

[0019] By adopting the above technical solution, the anti-lateral displacement system is optimized to support, fix and prevent lateral displacement of the assembled support frame. A pair of fastening nuts abut against each other on the support rod and can be locked with each other. A pair of fastening nuts can reliably support or press the positioning pad, and the positioning pad increases the contact area between the fastening nuts and the horizontal rod body. The support rod can more stably support and fix the horizontal rod body, that is, stably fix the assembled support frame; a U-shaped sleeve is added to the second anti-lateral displacement system, and the U-shaped sleeve abuts against the support rod, which can increase the abutment area between the end of the horizontal rod body and the support rod, optimize the force of the support rod, and adjust the upper end of the anti-lateral displacement rod to the same position as the horizontal rod body. The anti-lateral displacement rod body can more directly bear the force applied by the horizontal rod body, optimize the force, and have a better support effect.

[0020] Optionally, it also includes a cast-in-place structural plate fixed on the construction ground, the anti-lateral displacement system, the assembled support frame and the side formwork system are all arranged above the cast-in-place structural plate, and the anti-lateral displacement system is pre-buried in the cast-in-place structural plate.

[0021] By adopting the above technical scheme, the cast-in-place structural slab is cast on site, and the anti-lateral displacement system and the wall reinforcement ribs of the wall to be cast can be pre-embedded in the cast-in-place structural slab, which facilitates the installation and fixation of related structures, the connection strength between the wall to be cast and the ground structure is strong, and the fixation of the assembled support frame is stable and reliable.

[0022] Optionally, the side form system includes a template, secondary ribs, tension screws and nut fasteners, the secondary ribs are horizontally arranged support rods, the template is fixed to the load-bearing rods by the tension screws and nut fasteners, the secondary ribs are located between the template and the assembled support frame and are respectively abutted against both, and multiple secondary ribs are arranged along the vertical direction.

[0023] By adopting the above technical solution, the secondary ribs support the formwork laterally, and the force of the formwork is concentrated on the secondary ribs. The secondary ribs then transfer the force as a whole to the assembled support frame, thereby optimizing the force of the stressed assembled support frame; the formwork is fixed to the assembled support frame by tension screws and nut fasteners, and the formwork and the assembled support frame are firmly fixed and have a stable relative position, which is conducive to the formwork to stably maintain the outline of the cast wall.

[0024] Optionally, it also includes a support force adjustment system, which includes a detection component for detecting the verticality of the wall and a support component for supporting a local area of ​​the side form system, and the support force of the support component is adjustable.

[0025] By adopting the above technical solution, the detection component detects the verticality of the side form system, and the deformation of the local area is corrected by the support component. The supporting force of the support component is increased to push the side form system back to the correct position, thereby correcting the expansion deformation of the side form system.

[0026] Optionally, the detection assembly includes a verticality detection rod, a level detector fixed on the verticality detection rod, and a controller, the verticality detection rod is vertically arranged, the upper end of the verticality detection rod is hingedly fixed on the side mold system, the lower end of the verticality detection rod is in contact with the side mold system, the level detector is fixed on the verticality detection rod, and the level detector is electrically connected to the controller;

[0027] The support assembly includes a hydraulic cylinder hingedly fixed on the construction ground, the movable shaft end of the hydraulic cylinder is hingedly fixed to the lower area of ​​the side form system, the hydraulic cylinder is controlled by a solenoid valve, and the solenoid valve is electrically connected to the controller.

[0028] By adopting the above technical solution, during the concrete pouring process, since the concrete is in a fluid state, the lower part of the side form system will be subjected to greater force and prone to deformation, and the ultra-thick inner wall will be more affected during pouring; during the concrete solidification process, the heat dissipation of the lower concrete is poor, and the impact of the heat release caused by the concrete solidification is also greater. The area below the side form system is subjected to greater force and is more prone to expansion and deformation. When the lower area of ​​the side form system expands, the inclination of the verticality detection rod will change, which will cause the position of the level detector to change. The level detector then sends a signal to the solenoid valve through the controller to control the hydraulic cylinder to apply thrust to the side form system, thereby increasing the supporting force, restoring the side form system, and ensuring the quality of the wall.

[0029] On the other hand, the present application provides a construction method for an ultra-thick inner wall, comprising the following steps:

[0030] Step 1: determine the casting position of the wall to be cast, cast the cast-in-place structural plate, embed the anti-lateral displacement system and wall reinforcement in the cast-in-place structural plate, and set the anti-lateral displacement system on the surrounding side of the wall to be cast;

[0031] Step 2: Binding the complex steel bars and pipelines in the inner wall to be cast;

[0032] Step 3: Install the side formwork system on both sides of the interior wall to be poured;

[0033] Step 4: Install the assembled support frame, connect the assembled support frame with the anti-lateral displacement system, and fix the side mold system with the assembled support frame;

[0034] Step 5: pouring, vibrating and curing concrete;

[0035] Step six: dismantle the assembled support frame and side formwork system and cut off the embedded parts.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. By using an assembled support frame to support the side formwork system, the side formwork system forms a stable casting cavity. There will be no through-drawing screws in the casting cavity, avoiding the defects of the traditional fixing method of the drawing screws. The wiring in the casting wall will not be disturbed by the drawing screws, and the drawing screws will not form through holes in the casting wall. While ensuring the smooth casting of the cavity, the convenience of wiring and the density of the wall during the construction of ultra-thick inner walls are guaranteed. An anti-lateral movement system is set between the assembled support frame and the construction ground to prevent the assembled support frame from moving, thereby preventing the side formwork system from moving and ensuring that the contour of the wall meets the requirements;

[0038] 2. The main structure of the anti-lateral shift system is composed of vertically arranged support rods and obliquely arranged anti-lateral shift rods. The vertically arranged support rods can withstand large vertical loads, and the anti-lateral shift rods can withstand large horizontal loads. The extrusion force on the side mold system is transmitted to the anti-lateral shift system through the assembled support frame. The anti-lateral shift system can decompose the force into vertical force and horizontal force and act on the support rods and the anti-lateral shift rods respectively, so that the anti-lateral shift system can effectively support the assembled support frame and limit the lateral shift of the assembled support frame;

[0039] 3. By setting the overall profile of the assembled support frame to a triangle or a trapezoid, the assembled support frame can better convert the extrusion force on the side form system into a vertical force acting on the anti-lateral displacement system;

[0040] 4. By casting the cast-in-place structural slab at the construction site, on the one hand, it is convenient to firmly fix the anti-lateral displacement system by pre-embedding to ensure that the assembled support frame does not shift laterally. On the other hand, the cast wall can be better integrated with the cast-in-place structural slab, thereby improving the connection strength between the cast wall and the ground structure.

The upper end of 34 is welded and fixed to the support rod 33, and the lower end of the anti-lateral displacement rod 34 is inclined to the side away from the template 21; two pairs of fastening nuts 36 are screwed on the support rod 33, and a pair of fastening nuts 36 can be locked with each other to fix their own height position on the support rod 33, and two locking pads 37 are arranged between the two pairs of fastening nuts 36, and the locking pads 37 are sleeved on the support rod 33, and the horizontal rod body 13 is clamped and fixed between the two locking pads 37.

[0052] refer to Figure 1 and Figure 2 , the anti-lateral shift system 3 is provided with two corresponding to each assembled support frame 1, namely the first anti-lateral shift system 31 and the second anti-lateral shift system 32. The first anti-lateral shift system 31 is provided at one end of the assembled support frame 1 close to the side form system 2, the support rod 33 can support the assembled support frame 1, and the anti-lateral shift rod 34 can effectively withstand the horizontal force transmitted from the lower area of ​​the side form system 2, mainly reinforcing the lower part of the side form system 2 to prevent the lower part of the template 21 from lateral shift; the second anti-lateral shift system 32 is provided at one end of the assembled support frame 1 away from the side form system 2, and the second anti-lateral shift system 32 also includes a U-shaped sleeve 38, which is sleeved on the end of the horizontal rod body 13, and the U-shaped sleeve 38 is clamped and fixed between two clamping pads 37, and the support rod 33 is in contact with the U-shaped sleeve 38.

The anti-lateral displacement system 3 has a strong ability to withstand loads in all directions and can play a good anti-lateral displacement effect, thereby ensuring the stability of the wall contour; further setting the adjustment pad 39 to improve the tightness of the fit between the anti-lateral displacement system 3 and the assembled support frame 1 can ensure that the anti-lateral displacement system 3 can effectively support the assembled support frame 1.

[0055] Embodiment 2:

[0056] This embodiment discloses a tool-type support structure for reinforcing an ultra-thick inner wall. Figure 3 The difference between this embodiment and embodiment 1 is that it also includes a support force adjustment system 5, the support force adjustment system 5 includes a detection component 51 for detecting the verticality of the wall and a support component 52 for supporting a local area of ​​the side form system 2, and the support force of the support component 52 is adjustable.

[0057] refer to Figure 3 and Figure 4The detection assembly 51 includes an upper hinge rod 591, a lower hinge rod 592, a verticality detection rod 53, a level detector 54 fixed on the verticality detection rod 53, and a controller electrically connected to the level detector 54. The upper hinge rod 591 is fixed above the template 21, and the lower hinge rod 592 is fixed below the template 21. The upper hinge rod 591 is located directly above the lower hinge rod 592. The ends of the upper hinge rod 591 and the lower hinge rod 592 close to the template 21 are both welded and fixed with a rectangular metal mounting plate, and the metal mounting plate is fixed to the template 21 by bolts and nuts. At the same time, the secondary ribs 22 at the corresponding position are clamped between the metal mounting plate and the template 21; the upper end of the verticality detection rod 53 is hinged and fixed to the end of the upper hinge rod 591, and the lower end of the verticality detection rod 53 is welded and fixed with a rectangular plate-shaped movable hinge plate 5 31, a waist-shaped hole is provided on the movable hinge plate 531, and the end of the lower hinge rod 592 is connected to the waist-shaped hole on the movable hinge plate 531 through an axis part. When the lower area of ​​the side mold system 2 expands, it will push the lower end of the verticality detection rod 53 to deviate; the level detector 54 is fixed on the verticality detection rod 53. When the verticality detection rod 53 tilts, the position state of the level detector 54 will change and send a signal to the controller, and the controller controls the support assembly 52 to move; the controller can be integrated with the level detector 54 and remotely control the support assembly 52. ​​Since the area below the template 21 is greatly affected by fluid pressure and heat, and is also the area most prone to expansion, the verticality detection rod 53 mainly detects the expansion deformation of the area below the template 21.

[0058] refer to Figure 4 The level detector 54 is fixed on the verticality detection rod 53 through a sleeve 541. The sleeve 541 slides on the verticality detection rod 53. Bolts are screwed on the side wall of the sleeve 541. The bolts penetrate the sleeve 541 and abut against the verticality detection rod 53 to fix the position of the sleeve 541 on the verticality detection rod 53. The height position of the level detector 54 is adjustable. The closer the level detector 54 is to the movable hinge plate 531, the higher the detection sensitivity.

[0059] refer to Figure 3 and Figure 4The support assembly 52 includes a hinge mounting seat 571 fixed on the cast-in-place structural plate 4, a hydraulic cylinder 58 hingedly fixed on the hinge mounting seat 571, and a hinge abutment seat 572 hingedly mounted on the end of the movable shaft of the hydraulic cylinder 58. The hinge abutment seat 572 is welded and fixed on the metal mounting plate fixed with the lower hinge rod 592, and the hinge abutment seat 572 is at the same height as the secondary rib 22 at the corresponding position, that is, when the hydraulic cylinder 58 is started, the thrust directly acts on the secondary rib 22; embedded bolts 573 are pre-embedded in the cast-in-place structural plate 4, and the hinge mounting seat 571 is fixed on the embedded bolts 573; the hydraulic cylinder 58 is controlled by a solenoid valve, and the solenoid valve is controlled by a controller. The hydraulic cylinder 58 itself can play the role of supporting the lower area of ​​the template 21, and has a certain effect in preventing mold expansion; at the same time, when the template 21 and the secondary rib 22 are subjected to a large force and deformed, the verticality detection rod 53 will be tilted, and then the level detector 54 will no longer be horizontal and send a control signal through the controller. The hydraulic cylinder 58 starts and applies a thrust to the secondary rib 22 to reset the template 21 and the secondary rib 22. When the verticality detection rod 53 is reset, the signal of the controller stops and the hydraulic cylinder 58 stops moving.

[0060] refer to Figure 5 , multiple assembled support frames 1 are evenly arranged along the length direction of the secondary rib 22 to support the secondary rib 22 together, and the supporting force adjustment system 5 is arranged between two adjacent assembled support frames 1. The piston shaft of the hydraulic cylinder 58 abuts against the secondary rib 22 below the template 21 and is located in the middle position of the two adjacent assembled support frames 1; the area between the assembled support frames 1 is supported only by the secondary rib 22, and the force on the lower half of the template 21 will be very large, so this area is most prone to mold expansion. The lower hinge rod 592 detects the deformation of this area, and the hydraulic cylinder 58 supports this area, which can effectively detect the mold expansion changes of the side mold system 2 and make corrections.

[0061] The implementation principle of Example 2 is as follows: the lower half of the template 21 is subjected to the greatest force during the construction of ultra-thick walls. At the same time, due to its relatively closed location, the heat generated during the solidification of concrete is not easy to dissipate, and the lower half of the template 21 is prone to mold expansion. The verticality detection rod 53 cooperates with the lower hinge rod 592 to detect the deformation of the lower half of the template 21, and the hydraulic cylinder 58 corrects the deformation of the template 21.

[0062] The present application also discloses a construction method for an ultra-thick inner wall, comprising:

[0063] Step 1: determine the casting position of the wall to be cast on the construction ground 01, cast a layer of cast-in-place structural plate 4 at the casting position of the wall to be cast, embed the anti-lateral displacement system 3, embedded bolts 573 and wall reinforcement 03 in the cast-in-place structural plate, and set the anti-lateral displacement system 3 around the casting position of the wall to be cast;

[0064] Step 2: Binding the complex steel bars and pipelines in the inner wall to be cast;

[0065] Step 3, installing the side formwork system 2 on both sides of the interior wall to be cast;

[0066] Step 4: installing the assembled support frame 1 and the support force adjustment system 5, and assembling the assembled support frame 1 on site;

[0067] Step 5: pouring, vibrating and curing concrete;

[0068] Step six, dismantle the assembled support frame 1 and the side formwork system 2, and cut off the embedded parts.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
