Description

Technical Field

[0001] This invention belongs to the field of medical building structure technology, and in particular relates to a medical radiation shielding wall structure and construction method. Background Technology

[0002] Currently, proton therapy has seen rapid development due to its significantly smaller impact on the body compared to conventional radiotherapy. The core equipment for establishing a proton therapy center includes a fixed-beam therapy room, a cyclotron accelerator room, and multiple rotating gantry chambers. Most proton therapy centers occupy tens to hundreds of acres of land, requiring extensive radiation-shielding walls around the treatment equipment. On one hand, the main radiation source in the treatment area of ​​a proton therapy center is neutron radiation, which has extremely high penetrating power and is not easily absorbed, making conventional radiation-shielding walls ineffective. On the other hand, during the construction of a proton therapy center, conventional radiation-shielding walls cannot guarantee a proper seal between themselves and the building's structural finish, affecting not only the radiation protection effect but also making the construction of the building's structural finish extremely difficult. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a medical radiation shielding wall structure and construction method, which not only facilitates the construction of the decorative surface layer of the proton therapy center building structure, but also effectively shields the highly penetrating proton therapy equipment from radiation.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A medical radiation shielding wall structure includes a first square tube connected to the roof structure and a second square tube connected to the floor structure. The first square tube and the second square tube are connected by a third square tube to form a keel body. A multi-layer lead plate is also provided on one side of the keel body. The keel body forms a closed structure to form a radiation shielding space.

[0006] There is an adjustable gap between the first square tube and the roof surface structure. The bottom surface of the roof surface structure is connected to the side wall of the first square tube by a first angle steel so that the decorative surface layer can fill the gap.

[0007] In one embodiment, fireproof and soundproof walls are provided on both sides of the keel body, and the lead plate is disposed between the keel body and the fireproof and soundproof walls.

[0008] In one embodiment, the first square tube, the second square tube, and the third square tube are all steel square tube structures of the same size.

[0009] In one embodiment, a second angle steel is provided between the second square tube and the floor structure, the second angle steel is fixed to the floor structure by expansion anchor bolts, and the bottom of the second square tube is welded to the second angle steel.

[0010] In one embodiment, the second square tube and the expansion anchor bolt are arranged side by side in the same direction.

[0011] In one embodiment, the multiple layers of lead plates are arranged sequentially in a direction that gradually moves away from the keel body. The lead plate farthest from the keel body has a bent arc segment to form a closed mounting cavity with the adjacent lead plate. A pressure strip that fits against the lead plate is provided in the mounting cavity. A countersunk screw that penetrates the multiple layers of lead plates and connects to the keel body is provided on the pressure strip.

[0012] This invention also provides a construction method for a radiation-shielding wall structure, comprising the following steps:

[0013] Install a first square tube that connects to the roof structure;

[0014] An installation gap is reserved between the first square tube and the roof structure according to the thickness of the decorative surface layer;

[0015] The decorative surface layer is applied within the installation gap;

[0016] Install a second square tube that connects to the floor structure;

[0017] The first square tube and the second square tube are connected by a third-party pipe to form the main body of the keel;

[0018] The main body of the keel is enclosed into a closed structure, and multiple layers of lead plates are installed on the main body of the keel to form a radiation-proof space.

[0019] In one implementation, it further includes:

[0020] After the radiation-proof space is formed, fireproof and soundproof walls are installed on both sides of the main body of the keel.

[0021] In one implementation, it further includes:

[0022] When multiple lead plates are installed on the keel body, the multiple lead plates are sequentially installed in a direction that gradually moves away from the keel body. A bent arc segment is provided on the lead plate farthest from the keel body so that it forms a closed mounting cavity with the adjacent lead plate. A pressure strip that fits against the lead plate is provided in the mounting cavity, and countersunk screws that connect to the keel body are provided along the pressure strip and the multiple lead plates.

[0023] In one embodiment, an installation gap is pre-reserved between the first square tube and the roof surface structure according to the thickness of the decorative surface layer, including:

[0024] An L-shaped connector is installed on the roof surface structure, with one end of it fitting and fixed to the roof surface structure and the other end connected to the side wall of the first square tube, so that the installation gap is formed between the first square tube and the roof surface structure.

[0025] The beneficial effects of this invention are as follows:

[0026] First, a first square tube is installed on the roof structure using a first angle steel, leaving an installation gap between the first square tube and the roof structure that matches the size of the decorative surface layer. The decorative surface layer is then installed after the first square tube is installed. This method of installing part of the radiation protection structure first avoids the problems of finishing the joints and compromising the radiation protection effect when installing the decorative surface layer after the radiation protection wall is installed. The second square tube is connected to the floor structure via a second angle steel to reinforce the radiation protection wall. The lead plate on the outermost side of the main keel is set with a bent arc section to ensure the stability of the lead plate connection and to avoid affecting the radiation protection effect.

Detailed Implementation

[0036] The invention will now be further described with reference to the accompanying drawings.

[0037] For example, the main core equipment of the proton center project of a certain cancer hospital consists of three rotating gantry chambers, one fixed beam therapy chamber, and one cyclotron accelerator chamber. The main radiation source in the treatment area of ​​the proton therapy center is neutron rays, which have extremely high penetrating power and are not easily absorbed. Due to the different thicknesses of the decorative surface layer in different areas during the large-scale construction of the current radiation shielding wall structure in such places, it is difficult to construct the decorative surface layer between the wall and the roof structure. In actual construction, it is easy to damage the decorative surface layer when constructing the decorative surface layer on the radiation shielding wall, and it is also difficult to close the gap between the decorative surface layer and the radiation shielding wall, which easily damages the radiation shielding effect.

[0038] This invention provides a medical radiation shielding wall structure, such as... Figure 1 and Figure 3 As shown, it includes a first square tube 1 connected to the roof structure 2 and a second square tube 5 connected to the floor structure 6. The first square tube 1 and the second square tube 5 are connected by a third third tube 9 to form a keel body 10. A multi-layer lead plate 13 is also provided on one side of the keel body 10. The keel body 10 forms a closed structure to form a radiation protection space.

[0039] There is an adjustable gap between the first square tube 1 and the roof surface structure 2. The bottom surface of the roof surface structure 2 is connected to the side wall of the first square tube 1 by the first angle steel 3 so that the decorative surface layer 11 can fill the gap.

[0040] It should be noted that in this embodiment, the first angle steel 3 is used to connect the first square tube 1 and the roof surface structure 2, and an installation gap matching the size of the decorative surface layer 11 is reserved between the first square tube 1 and the roof surface structure 2. The decorative surface layer 11 is installed after the first square tube 1 is installed. That is, the radiation-proof wall is divided into multiple parts and installed sequentially. The upper part is installed first, and the remaining part of the radiation-proof wall is installed after the decorative surface layer 11 is installed to form the main body 10. This avoids the problem of finishing the decorative surface layer 11 during construction, ensures the radiation protection effect, and achieves the overall aesthetics of the building. At the same time, the L-shaped first angle steel 3 also makes it easy to adjust the distance of the installation gap between the first square tube 1 and the roof surface structure 2 to accommodate decorative surface layers 11 of different thicknesses in different areas.

[0041] Specifically, the first square tube 1, the second square tube 5, and the third square tube 9 are all steel square tube structures of the same size, which can be 50*30 steel square tube structures. The first square tube 1 is provided with an L50*5 first angle steel 3 with a length of 60mm between it and the roof surface structure 2, and is fixed to the bottom of the structural plate with M12*110 expansion bolts 4, while its other end is welded firmly to the side wall of the first square tube 1.

[0042] In one embodiment, such as Figure 2 As shown, a second angle steel 7 is provided between the second square tube 5 and the floor structure 6. The second angle steel 7 is fixed to the floor structure 6 by expansion anchor bolts 8. The bottom of the second square tube 5 is welded to the second angle steel 7. That is, the second angle steel 7 is provided on the floor structure 6 and connected to the second square tube 5 forming the bottom of the keel body 10, which further fixes the position of the keel body 10, improves the stability of the radiation shielding wall, and prevents gaps from appearing between it and the floor structure over time, thus affecting the radiation shielding effect.

[0043] Specifically, a second angle steel 7 of L50*5 is set between the second square tube 5 and the floor structure 6. The angle steel is 150mm long. Both ends of the second angle steel 7 are fixed to the floor structure 6 by M12*110 expansion anchor bolts 8. The area on the second angle steel 7 located between the expansion anchor bolts 8 is welded to the second square tube 5. At the same time, the second square tube 5 and the expansion anchor bolts 8 are set side by side in the same direction to further improve the connection stability between the keel body 10 and the floor structure.

[0044] In one embodiment, such as Figure 4 As shown, the multi-layer lead plates 13 are arranged sequentially in a direction that gradually moves away from the keel body 10. The lead plate 13 farthest from the keel body 10 has a bent arc segment 1301 to form a closed mounting cavity with the adjacent lead plate 13. A pressure strip 14 that fits against the lead plate 13 is provided in the mounting cavity. A countersunk screw 12 that penetrates the multi-layer lead plates 13 and connects to the keel body 10 is provided on the pressure strip 14.

[0045] It should be noted that the interconnection of the multi-layer lead plates 13 with each other and with the keel body 10 can improve the stability of the radiation-proof wall. However, the connection process can easily damage its radiation-proof effect. In this embodiment, the lead plate 13 located on the outermost side of the keel body 10 has a bent arc segment 1301. The end of the arc segment 1301 is attached to the adjacent lead plate 13, which forms an installation cavity while ensuring the sealing effect of the installation cavity. The pressure strip 14 and countersunk screw 12 set in the installation cavity can ensure the stability of the lead plate 13 connection and avoid affecting the radiation-proof effect of the wall.

[0046] Furthermore, such as Figure 5As shown, fireproof and soundproof walls 15 are also provided on both sides of the main body 10 of the keel, and lead plates 13 are placed between the main body 10 of the keel and the fireproof and soundproof walls 15.

[0047] In one embodiment, the present invention also provides a construction method for a radiation-shielding wall structure, comprising the following steps:

[0048] Step S10: Install the first square tube that connects to the roof structure;

[0049] Step S20: Based on the thickness of the decorative surface layer, reserve an installation gap between the first square tube and the roof surface structure;

[0050] Step S30: Apply the decorative surface layer within the installation gap;

[0051] Step S40: Install a second square pipe that connects to the floor structure;

[0052] Step S50: Connect the first square tube and the second square tube using a third-party tube to form the main body of the keel;

[0053] Step S60: Enclose the main body of the keel into a closed structure and install multiple layers of lead plates on the main body of the keel to form a radiation protection space;

[0054] It should be noted that in this embodiment, the method of installing part of the radiation protection structure first is adopted to avoid the trouble of finishing the decorative surface layer and the damage to the radiation protection effect when the radiation protection wall is installed after the decorative surface layer is installed. After the decorative surface layer is completed, the second square pipe and the third square pipe are set to form the main keel with the first square pipe, which ensures the building structure of the radiation protection wall. This not only facilitates the construction of the decorative surface layer and improves the construction efficiency, but also ensures the overall aesthetics of the building while avoiding affecting the radiation protection effect.

[0055] In one embodiment, a method for constructing a radiation-shielding wall structure includes the following steps:

[0056] Step S10: Install the first square tube that connects to the roof structure;

[0057] Step S20: Based on the thickness of the decorative surface layer, reserve an installation gap between the first square tube and the roof surface structure;

[0058] Specifically, an L-shaped connector is provided on the roof surface structure, with one end of it fitting and fixed to the roof surface structure and the other end connected to the side wall of the first square tube, so that the installation gap is formed between the first square tube and the roof surface structure. The L-shaped connector also makes it easy to adjust the distance of the installation gap between the first square tube and the roof surface structure to accommodate decorative surface layers of different thicknesses in different areas.

[0059] Step S30: Apply the decorative surface layer within the installation gap;

[0060] Step S40: Install a second square pipe that connects to the floor structure;

[0061] Specifically, a fastener is installed on the floor structure, and the second square tube is welded to the fastener to ensure a stable connection between the main keel and the floor structure;

[0062] Step S50: Connect the first square tube and the second square tube using a third-party tube to form the main body of the keel;

[0063] Step S60: Enclose the main body of the keel into a closed structure and install multiple layers of lead plates on the main body of the keel to form a radiation protection space;

[0064] Step S70: Fireproof and soundproof walls are installed on both sides of the main body of the keel;

[0065] Step S60 further includes:

[0066] Step S601: The multi-layer lead plates are sequentially arranged in a direction that gradually moves away from the main body of the keel;

[0067] Step S602: Set a bent arc segment on the lead plate farthest from the main body of the keel so as to form a closed mounting cavity between it and the adjacent lead plate.

[0068] Step S603: Set a pressure strip that fits against the lead plate in the mounting cavity, and set countersunk screws that connect to the keel body along the pressure strip and multiple layers of the lead plate;

[0069] By bending one end of the lead plate into an arc to form a closed installation cavity, the strength of the radiation shielding wall can be improved without affecting the radiation shielding effect, and no additional radiation shielding components are needed, thus saving costs.
