Description

Technical Field

[0001] This invention belongs to the field of through bolt technology, and specifically relates to a front-mounted through bolt installation method and construction method for wall base. Background Technology

[0002] Given the case studies of interior dry-hanging stone walls, TV background walls, and other wall-mounted steel frame or lightweight steel keel base construction in decoration projects, expansion bolts are typically used to fix the steel frame or lightweight steel keel to the wall. However, when encountering lightweight block brick walls, expansion bolts cannot be used, and through bolts must be installed to ensure the steel frame or lightweight steel keel structure is firmly fixed to meet its load-bearing requirements. When installing through bolts, to ensure the tie strength, there must be accessible space for workers on both the front and back of the wall. However, in actual construction, especially when constructing interior walls in residential projects, the other side of the block walls in areas such as elevator lobbies and equipment pipe shafts is adjacent to the residential unit. Since it is impossible for workers to normally enter the elevator shaft and equipment pipe shaft to tighten the through bolts from the back, traditional through bolts cannot be used in these types of walls. Currently, the steel frame or light steel keel for this type of wall is usually installed and fixed by inserting corner brackets into the floor slab at the top and bottom. This fixing method requires welding with an open flame, which is uneconomical, labor-intensive, time-consuming, and wasteful of materials. In order to ensure the design requirements, the keel is often far from the wall. When fixing the bottom corner bracket with expansion bolts, it is necessary to chisel to the surface of the floor slab, which damages the finished products such as underfloor heating pipes and affects their use, resulting in greater economic losses. Summary of the Invention

[0003] The main objective of this invention is to propose a method for installing through bolts on the front side of a wall, eliminating the need to work on the back side during construction.

[0004] This invention proposes a front-mounted through bolt, comprising:

[0005] A first component includes a first screw and a gravity rod, the gravity rod and the first screw being rotatably connected so that the first component assembly can switch between a horizontal state and a vertical state. In the horizontal state, the gravity rod and the first screw are arranged in parallel; in the vertical state, the gravity rod and the first screw are arranged orthogonally. The gravity rod includes a first segment and a second segment, with the connection area between the gravity rod and the first screw serving as a boundary. The center of gravity of the gravity rod is located on the first segment.

[0006] The second component includes a second screw and a hook at one end of the second screw, the hook being used to hook the first segment.

[0007] Furthermore, the length of the first segment is greater than the length of the second segment.

[0008] Furthermore, the first component also includes a bearing rod, the first screw includes a threaded rod body and a first nut without threads, the first nut is located at the end of the rod body and has a first through hole, the gravity rod also includes a second nut without threads connecting the first segment and the second segment, the second nut has a second through hole, and the gravity rod and the first screw are rotatably connected by the bearing rod.

[0009] Furthermore, the rod body is integrally formed with the first nut; and / or

[0010] The first segment, the second segment, and the second nut are integrally formed; and / or

[0011] The bearing rod also includes a bearing and two bearing caps. The bearing passes through the first through hole and the second through hole. The two bearing caps are respectively located at both ends of the bearing. One bearing cap is integrally formed with the bearing, and the other bearing cap is detachably connected to the bearing.

[0012] Furthermore, it also includes a third component, which includes a first fixing nut and a second fixing nut, wherein the first fixing nut is screwed to the first screw and the second fixing nut is screwed to the second screw.

[0013] Furthermore, the third component also includes a first washer and a second washer, wherein the first washer is used in conjunction with the first fixing nut and the second washer is used in conjunction with the second fixing nut.

[0014] The present invention also provides a construction method for the above-mentioned front-mounted through bolts, comprising the following steps:

[0015] Make an upper through hole and a lower through hole in the wall;

[0016] A first component in a horizontal state is inserted through the upper through hole. After the first screw is inserted through the upper through hole and the gravity rod is completely located on the back of the wall, the first component is controlled to switch from a horizontal state to a vertical state, and the lower end of the first section of the gravity rod is located on the lower side of the lower through hole.

[0017] A second component is inserted through the lower through hole so that the second screw is inserted through the lower through hole and the hook is located on the back of the wall.

[0018] Pull the second screw on the front of the wall so that the hook engages with the gravity bar; and

[0019] The two external fixing nuts are screwed to the first screw and the second screw respectively, so that both fixing nuts are pressed against the front of the wall. Alternatively, the first fixing nut and the second fixing nut are screwed to the first screw and the second screw respectively, so that both fixing nuts are pressed against the front of the wall.

[0020] Furthermore, in the step of controlling the first component to switch from a horizontal state to a vertical state, the first screw is controlled to rotate within the upper through hole.

[0021] Furthermore, the first step of inserting the first component in a horizontal state through the upper through hole is performed first, and then the second component is inserted through the lower through hole.

[0022] Between the step of switching the first component from a horizontal to a vertical state and the step of inserting the second component through the lower through hole, the method further includes the step of pulling the first screw on the front of the wall so that the gravity rod is in close contact with the back of the wall; and / or

[0023] In the step of inserting the second component through the lower through hole, the hook opening of the hook is located above or below the second screw. Before the step of pulling the second screw on the front of the wall, the second screw is rotated so that the hook opening of the hook and the second screw are on the same plane.

[0024] The present invention also provides a construction method for a wall base layer, comprising the following steps:

[0025] The above-described method for installing through-bolts is used to install through-bolts on the wall, wherein the positions of the upper and lower through holes correspond to the fixing positions of the joists in the wall base; and

[0026] Install the keel of the wall base on the first screw and the second screw.

[0027] Compared to traditional through-bolts, the aforementioned front-mounted through-bolts only require installation on the front of the wall, eliminating the need to work on the back. This allows for installation even when there is no space or access to the back of the wall, making it more versatile. Using these front-mounted through-bolts to install the wall base joists, compared to the traditional method of fixing the joists by inserting angle brackets into the floor slab at the top and bottom, eliminates the need for open-flame welding. This method is economical, time-saving, and material-efficient, and avoids damage to existing floor heating pipes or other finished installations, preventing significant economic losses. These front-mounted through-bolts are not only suitable for fixing wall bases in interior decoration but also for permanent fixing of indoor electromechanical systems such as fire protection and water supply / drainage pipes. For example, they can be used to permanently fix indoor pipes such as fire protection pipes or water pipes running vertically or horizontally along lightweight walls like masonry blocks, where conventional through-bolts are not feasible. Furthermore, the aforementioned through bolts for front mounting can be mass-produced and standardized in the factory, without being limited by site conditions or other factors. Orders can be placed in advance and installed directly on-site, which helps save construction time. The installation process is simple, requires low labor skills, and can save labor and material costs. On-site installation produces no waste and helps maintain a clean site appearance.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. 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.

[0036] like Figures 1-3 As shown, the present invention provides a front-mounted through bolt 10. The front-mounted through bolt 10 includes a first component 200 and a second component 300. The first component 200 includes a first screw (a threaded rod) 210 and a gravity rod 220. The gravity rod 220 and the first screw 210 are rotatably connected, such that the first component 200 can be assembled in a horizontal state (e.g., ...). Figure 2 (as shown) and vertical state (as shown) Figure 3 The system switches between the horizontal and vertical configurations. In the horizontal state, the gravity rod 220 and the first screw 210 are arranged in parallel. In the vertical state, the gravity rod 220 and the first screw 210 are arranged orthogonally (vertically). It should be noted that, in this embodiment, the parallel arrangement of the gravity rod 220 and the first screw 210 means that the gravity rod 220 and the first screw 210 are approximately parallel, and the gravity rod 220 and the first screw 210 can form a small included angle (less than 10°); the orthogonal arrangement of the gravity rod 220 and the first screw 210 (vertically) means that the gravity rod 220 and the first screw 210 are approximately orthogonal, and the angle formed by the gravity rod 220 and the first screw 210 is between 80° and 100°.

[0037] In this embodiment, the connection area between the gravity rod 220 and the first screw 210 serves as the dividing area. The gravity rod 220 includes a first segment 222 and a second segment 224, with the center of gravity of the gravity rod 220 located on the first segment 222. Specifically, in this embodiment, the length of the first segment 222 is greater than the length of the second segment 224. This makes it very easy to ensure that the center of gravity of the gravity rod 220 is located on the first segment 222. It is understood that in other embodiments, the length of the first segment 222 may be equal to or less than the length of the second segment 224. In this case, the center of gravity of the gravity rod 220 can be located on the first segment 222 by controlling the material of the first segment 222 to be different from that of the second segment 224 and / or by controlling the outer diameter of the first segment 222 to be different from that of the second segment 224. Specifically, in this embodiment, the material of the first segment 222 is the same as that of the second segment 224, and the outer diameter of the first segment 222 is the same as that of the second segment 224. More specifically, in this embodiment, the gravity rod 220 is a steel gravity rod.

[0038] The second component 300 includes a second screw (a threaded rod) 310 and a hook 320 located at one end of the second screw 310. The hook 320 is used to hook the first segment 222.

[0039] When installing the through bolt 10 on the wall, firstly, make an upper through hole and a lower through hole facing each other in the vertical direction on the wall, wherein the clear distance between the upper and lower through holes does not exceed the length of the first segment 222. Then, insert the first component 200 in a horizontal state through the upper through hole, with the first screw 210 inserted through the upper through hole and the gravity rod 220 completely located on the back of the wall, control the first component 200 to switch from a horizontal state to a vertical state, with the lower end of the first segment 222 of the gravity rod 220 located below the lower through hole. Next, pull the first screw 210 on the front of the wall to make the gravity rod 220 fit against the back of the wall. Then, insert the second component 300 through the lower through hole, with the second screw 310 inserted through the lower through hole and the hook 320 located on the back of the wall. Next, pull the second screw 310 on the front of the wall to make the hook 320 hook the gravity rod 220. Finally, screw the two external fixing nuts to the first screw 210 and the second screw 310 respectively, ensuring that both fixing nuts are firmly against the front of the wall, or screw the built-in first fixing nut 410 and second fixing nut 420 (e.g. Figure 4 and Figure 5 As shown, the first fixing nut 410 and the second fixing nut 310 are screwed onto the first screw 210 and the second fixing nut 310 respectively, so that the first fixing nut 410 and the second fixing nut 420 are both pressed against the front of the wall. After the installation of the through bolt 10 is completed on the front of the wall, the keel of the wall base can be installed on the first screw 210 and the second screw 220 on the front of the wall.

[0040] Compared to traditional through-bolts, the aforementioned front-mounted through-bolt 10 only requires installation on the front of the wall, eliminating the need to work on the back. This allows for installation even when there is no space or access to the back of the wall, making it more versatile. Using the aforementioned front-mounted through-bolt 10 to install the wall base joists, compared to the method of fixing the wall base joists by inserting angle brackets into the floor slab at the top and bottom, eliminates the need for open flame welding. This is economical, time-saving, and material-efficient, and avoids damage to completed installations such as underfloor heating pipes, preventing significant economic losses. The aforementioned front-mounted through-bolt 10 is not only suitable for fixing wall bases in interior decoration but also for permanent fixing of indoor electromechanical systems such as fire protection and water supply / drainage pipes. For example, it can be used for permanent fixing of indoor pipes such as fire protection pipes or water pipes running vertically or horizontally along lightweight walls such as masonry blocks, where conventional through-bolts are not feasible. Furthermore, the aforementioned through bolts 10 for front mounting can be mass-produced and standardized in the factory, without being limited by site conditions or other factors. Orders can be placed in advance and installed directly on-site, which helps save construction time. The installation process is simple, requires low labor skills, and can save labor and material costs. On-site installation produces no waste, which helps to ensure a clean site appearance.

[0041] In this embodiment, as Figures 1-3 As shown, the first component 200 also includes a bearing rod 230. The first screw 210 includes a threaded rod body 212 and a first nut 214 without threads. The first nut 214 is located at the end of the rod body 212. The first nut 214 has a first through hole 214a. The gravity rod 220 also includes a second nut 226 without threads connecting the first segment 222 and the second segment 224. The second nut 226 has a second through hole 226a. The gravity rod 220 and the first screw 210 are rotatably connected by the bearing rod 230. This makes it easier to manufacture the first component 200. Specifically, in this embodiment, the outer diameter of the first nut 214 is 16 mm and the inner diameter is 10 mm. The outer diameter of the second nut 226 is 16 mm and the inner diameter is 10 mm.

[0042] In this embodiment, the rod 212 and the first nut 214 are integrally formed. This makes it easier to manufacture the first screw 210.

[0043] In this embodiment, the first segment 222, the second segment 224, and the second nut 226 are integrally formed. This makes it easier to manufacture the gravity rod 220.

[0044] In this embodiment, the bearing rod 230 further includes a bearing 232 and two bearing caps 234. The bearing 232 passes through the first through hole 214a and the second through hole 226a. The two bearing caps 234 are respectively disposed at both ends of the bearing 232. One bearing cap 234 is integrally formed with the bearing 232, and the other bearing cap 234 is detachably connected to the bearing 232. This facilitates assembly and disassembly.

[0045] In this embodiment, as Figure 4 and Figure 5 As shown, the aforementioned front-mounted through bolt 10 also includes a third component 400. The third component 400 includes a first fixing nut 410 and a second fixing nut 420. The first fixing nut 410 is screwed to the first screw 210, and the second fixing nut 420 is screwed to the second screw 310. It is understood that in other embodiments, the aforementioned front-mounted through bolt 10 may not include the third component 400, and instead use two conventional fixing nuts available on the construction site to replace the third component 400.

[0046] In this embodiment, the third component 400 further includes a first washer 430 and a second washer 440. The first washer 430 is used in conjunction with the first fixing nut 410, and the second washer 440 is used in conjunction with the second fixing nut 420. Specifically, in this embodiment, both the first washer 430 and the second washer 440 are steel washers. The provision of the first washer 430 and the second washer 440 facilitates the fixed connection between the through bolt 10 and the wall. Specifically, in this embodiment, the first washer 430 and the second washer 440 have an outer diameter of 50 mm, an inner diameter of 10 mm, and a thickness of 3 mm. It is understood that in other embodiments, the first washer 430 and the second washer 440 may be omitted.

[0047] like Figure 6 As shown, the present invention also provides a construction method for front-mounted through bolts, comprising the following steps:

[0048] Step S61 0: An upper through hole and a lower through hole are formed in the wall. Specifically, in this embodiment, the diameters of the upper and lower through holes are the same, which facilitates the construction of the upper and lower through holes. It is understood that in other embodiments, the diameters of the upper and lower through holes may be different. More specifically, in this embodiment, the diameters of both the upper and lower through holes are 35mm.

[0049] In step S620, a first component in a horizontal state is inserted through the upper through hole, and a first screw is inserted through the upper through hole. After the gravity rod is completely positioned on the back of the wall, the first component is controlled to switch from a horizontal state to a vertical state, and the lower end of the first section of the gravity rod is located below the lower through hole. Specifically, the lower end of the first section of the gravity rod is located below the lower through hole, meaning the net distance between the upper and lower through holes does not exceed the length of the first section of the gravity rod.

[0050] In some embodiments, when the gravity rod is completely behind the wall, the first component can automatically switch from a horizontal to a vertical state under the influence of gravity. In some embodiments, when the gravity rod is completely behind the wall, the first component cannot automatically switch from a horizontal to a vertical state under the influence of gravity. In this case, the first screw can be held on the front of the wall and slowly rotated to switch the first component from a horizontal to a vertical state. The fact that the first component cannot automatically switch from a horizontal to a vertical state under the influence of gravity indicates that the horizontal state of the first component is relatively stable, which is very beneficial for inserting a horizontally positioned first component through the upper through hole.

[0051] In some embodiments, prior to step S630, the method further includes pulling the first screw on the front of the wall so that the gravity bar is in close contact with the back of the wall.

[0052] Step S 630: Insert the second component through the lower through hole so that the second screw passes through the lower through hole and the hook is located on the back of the wall.

[0053] In some embodiments, step S620 is performed first, followed by step S630, thus preventing the second component from interfering with the first component's transition from a horizontal to a vertical state. In some embodiments, step S630 may be performed first, followed by step S620. In some embodiments, steps S620 and S630 may be performed simultaneously. That is, there is no restriction on the order of steps S620 and S630.

[0054] Step S640: Pull the second screw on the front of the wall so that the hook catches the gravity bar.

[0055] In this embodiment, in step S630, the hook opening of the hook is located above or below the second screw. Before step S640, the second screw is rotated so that the hook opening of the hook and the second screw are on the same plane. This prevents the gravity rod located at the lower through hole from interfering with the hook of the second screw passing through the lower through hole. It can be understood that in other embodiments, when step S630 is performed first and then step S620, the hook opening of the hook and the second screw may also be on the same plane in step S630.

[0056] Step S650: Connect the two external fixing nuts to the first screw and the second screw respectively, so that both fixing nuts are pressed against the front of the wall; or connect the built-in first fixing nut and the second fixing nut to the first screw and the second screw respectively, so that both the first fixing nut and the second fixing nut are pressed against the front of the wall.

[0057] like Figure 7 As shown, the present invention also provides a construction method for a wall base layer, comprising the following steps:

[0058] Step S710: Install through bolts on the wall using the front-mounted through bolt construction method, wherein the positions of the upper and lower through holes correspond to the fixing positions of the keel of the wall base.

[0059] Step S720: Install the keel of the wall base on the first screw and the second screw.
