Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a tensioning component. Background Technology

[0002] With the rapid development of the construction industry, the use of steel truss floor decking is gradually increasing. However, due to the large span and heavy weight of the steel truss floor decking, it is relatively difficult to tension the joints between the slabs during installation. If the floor decking is not tensioned during installation, grout leakage is likely to occur at the joints during the pouring process.

[0003] In related technologies, a cross-shaped pry bar is typically used to pry open the floor decking to be installed and the already installed floor decking to achieve tension between them. However, the distance between the two handles of the pry bar is relatively small, usually allowing only one person to operate it. When the floor decking is too heavy and multiple people need to operate the cross-shaped pry bar together, the small distance between the two handles is insufficient to provide the necessary operating space for multiple workers to work together. Therefore, it is impossible to achieve effective tension between the floor decking and ensure the installation quality of the floor decking. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a tensioning assembly that can be easily switched between single-person or multi-person operation, is suitable for tensioning and installing floor decking of various specifications, and ensures the installation quality of the floor decking.

[0005] To achieve the above objectives, embodiments of the present invention provide a tensioning assembly for tensioning a first floor deck and a second floor deck, the tensioning assembly comprising:

[0006] The first member includes a first hand-held end and a first tensioning end opposite each other along its extension direction. The first tensioning end is used to abut against the first floor deck. The first member also includes a first bend, and the first hand-held end is connected to the first bend.

[0007] The second member includes a second hand-held end and a second tensioning end that are opposite each other along its extension direction. The second member and the first member are arranged opposite each other along a first direction. The second tensioning end is used to abut against the second floor deck. The second member also includes a second bend. The second hand-held end is connected to the second bend. The second hand-held end can approach the first hand-held end along a second direction so that the second tensioning end approaches the first tensioning end along the second direction. The second direction intersects the first direction.

[0008] The first rod is configured to have a first position and a second position. In the first position, the first hand-held end and the second hand-held end are spaced apart by a first distance. In the second position, the first hand-held end and the second hand-held end are spaced apart by a second distance. The first hand-held end can switch between the first position and the second position by rotating relative to the second hand-held end along its own axis.

[0009] In some embodiments, the second hand-held end can approach the first hand-held end along the first direction, so that the second tensioning end approaches the first tensioning end along the first direction.

[0010] In some embodiments, the first bent portion protrudes from the first rod in a direction away from the second rod, the second bent portion protrudes from the second rod in a direction away from the first rod, and the first bent portion and the second bent portion are arranged opposite to each other in the second direction.

[0011] In some embodiments, the tensioning assembly includes a base sleeved on the outer periphery of the first tensioning end. The base includes a first baffle and a second baffle arranged opposite to each other along the first direction. The base also includes a third baffle, with the first baffle and the second baffle connected to each end of the third baffle along the first direction. The third baffle is disposed on the side of the first member opposite to the second member.

[0012] In some embodiments, the base includes a first mounting hole penetrating the first baffle and the second baffle along the first direction, the second rod includes a connecting rod and a second mounting hole, the connecting rod extends out of the second rod along the first direction and toward the first rod, the second mounting hole is provided at one end of the connecting rod opposite to the second rod, and the tensioning assembly includes a rotating shaft passing through the first mounting hole and the second mounting hole, so that the second handheld end approaches the first handheld end along the second direction.

[0013] In some embodiments, the first mounting hole extends along the axial direction, which is perpendicular to both the first and second directions. The tensioning assembly includes a plurality of pads disposed in the first mounting hole. The plurality of pads are stacked along the axial direction so that the second tensioning end approaches the first tensioning end along the first direction.

[0014] In some embodiments, the first tensioning end is provided with a first angle steel, and the first angle steel abuts against the first floor deck;

[0015] And / or,

[0016] The second tensioning end is provided with a second angle steel, which abuts against the second floor deck.

[0017] In some embodiments, the extension length of the first rod is L1, where 0.8m ≤ L1 ≤ 1.2m;

[0018] And / or,

[0019] The extension length of the second member is L2, where 0.8m ≤ L2 ≤ 1.2m.

[0020] In some embodiments, the first rod and the second rod have the same extension length.

[0021] In some embodiments, the cross-section of the first rod along the first direction is cylindrical;

[0022] And / or,

[0023] The cross-section of the second member along the first direction is cylindrical.

[0024] According to the above embodiments, the beneficial effects of the present invention are:

[0025] In the technical solution of this application, the first and second rods are combined to form a tensioning assembly. When force is applied to bring the second hand-held end closer to the first hand-held end in a second direction, the second tensioning end can also move closer to the first tensioning end in the second direction, achieving tension between the floor decking to be installed and the already installed floor decking. This facilitates the close connection between the first and second floor deckings during installation and prevents grout leakage during floor decking pouring. When multiple people need to operate the tensioning assembly to tension large-sized floor deckings, the first rod can be positioned in the first position, thereby increasing the distance between the two hand-held ends to provide ample operating space for multiple workers. When a single person needs to operate the tensioning assembly to tension small-sized floor deckings, the first rod can be positioned in the second position, thereby bringing the distance between the two hand-held ends closer for convenient single-person operation. Switching between the first and second positions only requires rotating the first rod, making operation convenient and quick. Therefore, the tensioning assembly of this solution is suitable for tensioning various sizes of floor deckings and can ensure the installation quality of the floor deckings.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0044] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0045] In related technologies, a cross-shaped pry bar is typically used to pry open the floor decking to be installed and the already installed floor decking to achieve tension between them. However, the distance between the two handles of the pry bar is relatively small, usually allowing only one person to operate it. When the floor decking is too heavy and multiple people need to operate the cross-shaped pry bar together, the small distance between the two handles is insufficient to provide the necessary operating space for multiple workers to work together. Therefore, it is impossible to achieve effective tension between the floor decking and ensure the installation quality of the floor decking.

[0046] The applicant also found that existing cross crowbars have poor versatility. When using a cross crowbar with a large gap (meaning a larger distance between the two handles) to tension lighter floor decking, the large distance between the handles makes single-person operation difficult and inconvenient. When using a cross crowbar with a small gap (meaning a smaller distance between the two handles) to tension heavier floor decking, the small distance between the handles does not provide sufficient operating space for multiple workers. In summary, existing cross crowbars are not suitable for tensioning and installing floor decking of various sizes and weights.

[0047] In view of this, this application proposes a tensioning component 10, which is used to tension the first floor decking and the second floor decking during building construction, ensuring the installation quality of the floor decking and preventing grout leakage during floor decking pouring. It should be noted that the first floor decking refers to the floor decking that has been installed, and the second floor decking refers to the floor decking to be installed. The following references... Figures 1 to 8 The tensioning assembly 10 according to an embodiment of the present invention will be described below. Specifically, the tensioning assembly 10 includes a first rod 100 and a second rod 200.

[0048] Reference Figure 7 The first member 100 includes a first hand-held end 110 and a first tensioning end 120 opposite each other along its extension direction. It is understood that the extension direction of the first member 100 refers to the extension direction of the main body portion of the first member 100. The first tensioning end 120 is used to abut against the first floor deck.

[0049] The first member 100 further includes a first bend. In some embodiments, the first bend may be bent obliquely relative to the main body of the first member 100. In other embodiments, the first bend may be bent perpendicularly relative to the main body of the first member 100. This application embodiment uses a perpendicular bend as an example, referring to... Figure 1 , Figure 3 , Figure 4 as well as Figures 6 to 8 .

[0050] Reference Figure 8 The second member 200 includes a second hand-held end 210 and a second tensioning end 220 that are opposite each other along its extension direction. It is understood that the extension direction of the second member 200 refers to the extension direction of the main body of the second member 200. The second member 200 is arranged opposite to the first member 100 along a first direction X. The second tensioning end 220 is used to abut against the second floor deck.

[0051] The second member 200 includes a second bent portion, which is similar in arrangement to the first bent portion. That is, the second bent portion can be bent at an angle relative to the main body of the second member 200, or it can be bent perpendicularly relative to the main body of the second member 200. The second handheld end 210 is connected to the second bent portion.

[0052] The second direction Y intersects the first direction X, meaning the second direction Y can be perpendicular to the first direction X, or it can intersect at other angles. In some embodiments, the second direction Y being perpendicular to the first direction X is taken as an example.

[0053] The second hand-held end 210 of the second member 200 can approach the first hand-held end 110 of the first member 100 along the second direction Y, so that the second tensioning end 220 approaches the first tensioning end 120 along the second direction Y, thereby tensioning the first floor deck and the second floor deck. In other words, the second member 200 can achieve tensioning by rotating relative to the first member 100. The tensioning state can be referred to... Figure 4 It is understandable that when the second hand-held end 210 moves away from the first hand-held end 110 along the second direction Y, the second tensioning end 220 will also move away from the first tensioning end 120 along the second direction Y.

[0054] The first member 100 is configured to have a first position and a second position. In the first position, refer to... Figure 1 The first hand-held end 110 and the second hand-held end 210 are spaced apart by a first distance. This allows for tensioning between the first and second floor decks using two or more people in the first position. In the second position, refer to... Figure 3 The first handheld end 110 and the second handheld end 210 are spaced a second distance apart. It can be understood that in the second position, tension between the first floor deck and the second floor deck can be achieved by a single person. The first handheld end 110 can switch between the first and second positions by rotating relative to the second handheld end 210 along its own axis direction Z, in order to adapt to the needs of different operating scenarios.

[0055] In the technical solution of this application, the first rod 100 and the second rod 200 are combined to form a tensioning assembly 10. When force is applied to bring the second hand-held end 210 closer to the first hand-held end 110 along the second direction Y, the second tensioning end 220 can also move closer to the first tensioning end 120 along the second direction Y, thereby achieving tension between the floor decking to be installed and the already installed floor decking. This facilitates the close connection between the first and second floor deckings during installation and prevents grout leakage during floor decking pouring. When multiple people need to operate the tensioning assembly 10 to tension large-sized floor deckings, the first rod 100 can be placed in the first position, thereby increasing the distance between the two hand-held ends to provide sufficient operating space for multiple workers. When a single person needs to operate the tensioning assembly 10 to tension small-sized floor deckings, the first rod 100 can be placed in the second position, thereby increasing the distance between the two hand-held ends for convenient single-person operation. When it is necessary to switch between the first position and the second position, simply rotate the first rod 100. The operation is convenient and quick. Therefore, the tensioning component 10 of this solution is suitable for tensioning scenarios of floor decking of various specifications and can ensure the installation quality of floor decking.

[0056] In some embodiments, refer to Figure 6 The second hand-held end 210 of the second rod 200 can approach the first hand-held end 110 of the first rod 100 along the first direction X, so that the second tensioning end 220 approaches the first tensioning end 120 along the first direction X.

[0057] Since the second tensioning end 220 can abut against the second floor decking, and the first tensioning end 120 can abut against the first floor decking, it can be understood that when the second tensioning end 220 approaches the first tensioning end 120 along the first direction X, the second floor decking can move relative to the first floor decking along the first direction X. In other words, the tensioning assembly 10 can adjust the position of the second floor decking relative to the first floor decking along the first direction X, that is, the tensioning assembly 10 can adjust the alignment of adjacent floor deckings along the first direction X, further improving the installation accuracy of the floor decking and ensuring the installation quality of the floor decking.

[0058] In some embodiments, a first bent portion protrudes from the first rod 100 in a direction opposite to the second rod 200, and a second bent portion protrudes from the second rod 200 in a direction opposite to the first rod 100. The first bent portion and the second bent portion are arranged opposite to each other in a second direction Y. The provision of the first bent portion and the second bent portion enables the first handheld end 110 to have a first distance and a second distance after rotating relative to the second handheld end 210 in its own axial direction Z. That is, it provides sufficient operating space when the tensioning assembly 10 requires multiple people to operate, and the distance between the first handheld end 110 and the second handheld end 210 is reduced when operating by a single person, thereby facilitating operation.

[0059] Reference Figures 1 to 7 The tensioning assembly 10 includes a base 140, which is sleeved on the outer periphery of the first tensioning end 120. It is understood that a sleeve can be added inside the base 140 to connect with the main body of the first rod 100. The base 140 includes a first baffle 141, a second baffle 142, and a third baffle arranged opposite each other along a first direction X. The third baffle connects the first baffle 141 and the second baffle 142 at both ends along the first direction X. The third baffle is located on the side of the first rod 100 opposite to the second rod 200. The base 140 allows the first rod 100 to rotate relative to the second rod 200, facilitating the switching of the first rod 100 between a first position and a second position.

[0060] It is understandable that the inner sleeve of the base 140 can be provided with a threaded hole, and the outer periphery of the first tensioning end 120 can be provided with a thread, so that the first rod 100 can rotate inside the base 140.

[0061] In some embodiments, a steel plate may be welded inside the base 140 to improve the connection strength between the base 140 and the connecting rod 240. In other embodiments, a shim may be added at the connection between the connecting rod 240 and the base 140. Specifically, the thickness of the shim may be 0.8mm to 1.2mm. For example, the shim may be 0.8mm, 0.9mm, 1.1mm, or 1.2mm, etc.

[0062] Reference Figure 1, Figure 2 , Figure 5 and Figure 7 The base 140 includes a first mounting hole 144 extending along a first direction X through the first baffle 141 and the second baffle 142. The second rod 200 includes a connecting rod 240 and a second mounting hole 241, as shown in the figure. Figure 7 The connecting rod 240 extends out of the second member 200 along the first direction X and extends toward the first member 100. The second mounting hole 241 is provided at the end of the connecting rod 240 opposite to the second member 200.

[0063] The tensioning assembly 10 includes a rotating shaft 300, which passes through a first mounting hole 144 and a second mounting hole 241 to connect a first rod 100 and a second rod 200, allowing a second handheld end 210 to approach a first handheld end 110 along a second direction Y. In other words, the rotating shaft 300 passing through the first mounting hole 144 and the second mounting hole 241 allows the first rod 100 to rotate relative to the second rod 200 to achieve the corresponding tensioning function. It is understood that grease can be applied to the connection between the connecting rod 240 and the first rod 100 to allow the first rod 100 to rotate more smoothly relative to the second rod 200.

[0064] It should be noted that, on the basis of ensuring sufficient displacement between the first tensioning end 120 and the second tensioning end 220, that is, on the basis that the floor deck can be tensioned, the first connecting hole can be made as far away from the first tensioning end 120 as possible. This is equivalent to making the connection fulcrum between the first rod 100 and the second rod 200 as close as possible to the first tensioning end 120, thereby reducing the force required by the hand and making it easier for the staff to operate.

[0065] Reference Figures 1 to 7 The first mounting hole 144 extends along the axial direction Z. The axial direction Z is perpendicular to both the first direction X and the second direction Y. The tensioning assembly 10 includes a plurality of pads 145 disposed in the first mounting hole 144. In some embodiments, the outer contour of the pad 145 may be crescent-shaped. In other embodiments, the outer contour of the pad 145 may be a rectangle with grooves. In still other embodiments, the outer contour of the pad 145 may be a semi-circular ring. Some embodiments of this application use a crescent-shaped pad 145 as an example.

[0066] Reference Figure 4 and Figure 5 Multiple pads 145 are stacked along the axial direction Z, allowing the second tensioning end 220 to approach the first tensioning end 120 along the first direction X. This achieves displacement of the second floor deck relative to the first floor deck along the first direction X, thereby adjusting the installation accuracy between adjacent floor decks. This ensures the installation quality of the floor deck and prevents grout leakage during pouring.

[0067] It is understandable that, in order to ensure that the shaft 300 is securely connected as the second tensioning end 220 approaches the first tensioning end 120 along the first direction X, the two ends of the shaft 300 can extend beyond the outer sides of the first baffle 141 and the second baffle 142, respectively. That is, the length of the shaft 300 along the first direction X is greater than the maximum length of the third baffle along the first direction X.

[0068] In some embodiments, the first tensioning end 120 is provided with a first angle steel, which abuts against the first floor deck. Providing the first angle steel can increase the contact area between the first member 100 and the floor deck, so that the point-like concentrated load during the tensioning and interlocking process of the first member 100 and the floor deck is transformed into a uniformly distributed load, effectively solving the problem of grout leakage during subsequent floor slab pouring caused by uneven tension due to point-like stress during the floor deck installation process.

[0069] Additionally, a second angle steel is provided at the second tensioning end 220, which abuts against the second floor deck. The effect of the second angle steel is similar to that of the first angle steel, and will not be described further here.

[0070] In some embodiments, the extension length of the first member 100 is L1, where 0.8m ≤ L1 ≤ 1.2m. Exemplarily, the first member 100 can be 0.8m, 0.85m, 0.9m, 1m, or 1.2m, etc. It should be noted that the extension length of the first member 100 here refers to the overall extension height of the first member 100 along the axial direction Z.

[0071] Additionally, the extension length of the second member 200 is L2, where 0.8m ≤ L2 ≤ 1.2m. For example, the second member 200 can have lengths of 0.8m, 0.84m, 0.95m, 1m, or 1.2m, etc. It should be noted that the extension length of the second member 200 here refers to the overall extension height of the second member 200 along the axial direction Z.

[0072] The length settings of the first rod 100 and the second rod 200 are in line with the height and operating habits of the relevant operators, making it easier for them to perform tensioning and other operations more comfortably.

[0073] In some embodiments, the extension length of the first member 100 may be equal to the extension length of the second member 200. This facilitates user operation.

[0074] Furthermore, the first member 100 has a cylindrical cross-section along the first direction X; specifically, the first member 100 can be a steel pipe. Similarly, the second member 200 has a cylindrical cross-section along the first direction X; specifically, the first member 100 can be a steel pipe. Steel pipes are easy for users to hold and readily available on construction sites, improving material utilization and reducing construction costs. Specifically, the steel pipe can be φ32mm in size.

[0075] In some embodiments, both the first hand-held end 110 and the second hand-held end 210 of the tensioning assembly 10 can be welded with handles. In other embodiments, the first hand-held end 110 and the second hand-held end 210 can also be connected with bolts to serve as grips. The above arrangement facilitates gripping by relevant operators and makes it easier for workers to operate the tensioning assembly 10.

[0076] The operation methods of the tensioning component 10 in some embodiments are described in detail below.

[0077] Place the steel truss slab (second floor deck) to be installed in the designated position, ensuring that the positions of the connection joints are aligned.

[0078] The first tensioning end 120 and the second tensioning end 220 of the tensioning assembly 10 are respectively abutted against the bottom reinforcing bars of the first floor deck (the installed steel truss slab) and the second floor deck (the steel truss slab to be installed). When two or more people are required to operate (when the floor deck is large and heavy), the first hand-held end 110 and the second hand-held end 210 are spaced apart by a first distance (in a first position), as shown in the reference. Figure 1 Force is applied to bring the first hand-held end 110 closer to the second hand-held end 210 along the second direction Y, thereby bringing the first floor deck closer to and abutting against the second floor deck to complete tensioning. Then, the reinforcing bars on the floor deck are welded to the upper surface of the steel beam to reinforce it, completing the installation. When single-person operation is required, the first hand-held end 110 and the second hand-held end 210 are spaced a second distance apart (in a second position), as shown in the reference. Figure 3 Force is applied to bring the first hand-held end 110 closer to the second hand-held end 210 along the second direction Y, and then tensioned and welded to complete the paving.

[0079] It should be noted that when the first and second floor deckings shift along the first direction X, force can be applied to move the second hand-held end 210 closer to the first hand-held end 110 along the first direction X, thereby moving the second tensioning end 220 closer to the first tensioning end 120 along the first direction X. Similarly, force can be applied to move the second hand-held end 210 away from the first hand-held end 110 along the first direction X, thereby moving the second tensioning end 220 away from the first tensioning end 120 along the first direction X. This method can achieve positional adjustment of the first and second floor deckings along the first direction X, ensuring the assembly accuracy of the first and second floor deckings and preventing grout leakage during floor decking pouring.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
