Description

Tensioning assembly

Technical Field

The utility model relates to the technical field of building construction, in particular to a tensioning assembly.

Background

With the rapid development of the building industry, the use of steel bar truss floor support plates is gradually increased. However, because the span of the erection of the steel bar truss floor support plate is large and the plate weight is heavy, the tensioning of the joint of the plate and the plate seaming is relatively difficult in the installation process of the steel bar truss floor support plate, and when the floor support plate is not in tensioning installation, the floor support plate is easy to leak slurry at the seaming in the casting process.

In the related art, cross crow bars are generally adopted to pry the floor support plate to be installed and the floor support plate which is installed respectively, so that tensioning between the floor support plates is realized. However, the space between the two hand-held ends of the crow bar is smaller, and the crow bar can only be operated by a single person, and when the floor carrier plate is too heavy and a plurality of people are required to operate the cross crow bar together, the distance between the two hand-held ends of the crow bar is too small, so that the operation space required by the common construction of a plurality of workers can not be provided. Therefore, effective tensioning between the floor support plates cannot be realized and the installation quality of the floor support plates cannot be guaranteed.

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that, if a directional indication (such as up, down, left, right, front, and rear … …) is included in the embodiment of the present utility model, the directional indication is merely used to explain a relative positional relationship, a movement condition, and the like between the components in a specific posture, and if the specific posture is changed, the directional indication is correspondingly changed.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, if "and/or", "and/or" and/or "are used throughout, the meaning includes three parallel schemes, for example," a and/or B ", including a scheme, or B scheme, or a scheme where a and B meet simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.

In the related art, cross crow bars are generally adopted to pry the floor support plate to be installed and the floor support plate which is installed respectively, so that tensioning between the floor support plates is realized. However, the space between the two hand-held ends of the crow bar is smaller, and the crow bar can only be operated by a single person, and when the floor carrier plate is too heavy and a plurality of people are required to operate the cross crow bar together, the distance between the two hand-held ends of the crow bar is too small, so that the operation space required by the common construction of a plurality of workers can not be provided. Therefore, effective tensioning between the floor support plates cannot be realized and the installation quality of the floor support plates cannot be guaranteed.

The applicant has also found that the current cross crowbar has poor versatility. When the floor carrier plate with small weight is tensioned by the crossed crowbars with large spacing (larger spacing between two handheld ends), the floor carrier plate is laborious and inconvenient for a single person to hold the floor carrier plate with large spacing between the handheld ends. When a floor carrier plate of a large weight is tensioned by using a cross crow bar of a small pitch (which means that the pitch between two hand-held ends is small), a sufficient operation space cannot be provided for a plurality of workers because the pitch between the two hand-held ends is too small. To sum up, the existing cross crow bar cannot be suitable for tensioning installation scenes of floor carrier plates with different specifications and weights.

In view of this, the present utility model proposes a tensioning assembly 10, wherein the tensioning assembly 10 is used for tensioning between a first floor support plate and a second floor support plate in building construction, ensuring the installation quality of the floor support plates, and preventing slurry leakage during pouring of the floor support plates. It should be noted that the first floor support plate refers to a floor support plate that has been installed, and the second floor support plate refers to a floor support plate to be installed. A tensioning assembly 10 according to an embodiment of the present utility model is described below with reference to fig. 1-8. Specifically, the tensioning assembly 10 includes a first rod 100 and a second rod 200.

Referring to fig. 7, the first lever 100 includes a first hand-held end 110 and a first tensioning end 120 opposite in the direction of extension thereof. It is understood that the extending direction of the first pin 100 refers to the extending direction of the main body portion of the first pin 100. The first tensioning end 120 is used for abutting against the first floor support plate.

The first rod member 100 further includes a first bending portion. In some embodiments, the first bending portion may bend obliquely with respect to the main body portion of the first lever 100. In other embodiments, the first bending portion may be bent perpendicularly with respect to the main body portion of the first lever 100. In the embodiment of the present utility model, the vertical bending is taken as an example, and refer to fig. 1, 3, 4 and 6 to 8.

Referring to fig. 8, the second lever 200 includes a second hand-held end 210 and a second tensioning end 220 opposite in the direction of extension thereof. It is understood that the extending direction of the second pin 200 refers to the extending direction of the main body portion of the second pin 200. The second lever 200 is disposed opposite to the first lever 100 in the first direction X. The second tensioning end 220 is used to abut against the second floor support plate.

The second rod 200 includes a second bending portion, which is similar to the first bending portion. That is, the second bending portion may be bent obliquely with respect to the main body portion of the second rod 200, and the second bending portion may also be bent perpendicularly with respect to the main body portion of the second rod 200. The second hand-held end 210 is connected to the second bending portion.

The second direction Y intersects the first direction X, i.e. the second direction Y may be perpendicular to the first direction X or may intersect at other angles. In some embodiments, the second direction Y is perpendicular to the first direction X.

The second hand-held end 210 of the second rod 200 can be close to the first hand-held end 110 of the first rod 100 along the second direction Y, so that the second tensioning end 220 is close to the first tensioning end 120 along the second direction Y, thereby tensioning between the first floor support plate and the second floor support plate. In other words, the second rod member 200 can be cross-rotated with respect to the first rod member 100 to achieve tensioning, and the tensioning state may refer to fig. 4. It will be appreciated that as the second handheld end 210 moves away from the first handheld end 110 in the second direction Y, the second tensioning end 220 also moves away from the first tensioning end 120 in the second direction Y.

Wherein the first lever 100 is configured to have a first position and a second position. In the first position, referring to fig. 1, the first hand-held end 110 is spaced a first distance from the second hand-held end 210, it being understood that a double or multiple person operation may be used to tighten the first floor support plate and the second floor support plate in the first position. In the second position, referring to fig. 3, the first hand-held end 110 is spaced a second distance from the second hand-held end 210, it being understood that in the second position the tension between the first floor support plate and the second floor support plate can be applied by a single operator. The first handheld end 110 is rotated along its own axis direction Z relative to the second handheld end 210, so as to switch between the first position and the second position, so as to adapt to the needs of the unused operation scene.

In the solution of the present utility model, the first rod 100 and the second rod 200 are combined to form the tensioning assembly 10. When the second handheld end 210 is close to the first handheld end 110 along the second direction Y by applying force, the second tensioning end 220 can be close to the first tensioning end 120 along the second direction Y, tensioning between the floor support plate to be installed and the floor support plate installed is achieved, the first floor support plate and the second floor support plate are convenient to install and connect after being abutted against each other, and slurry leakage is prevented when the floor support plate is poured. When the tensioning assembly 10 is operated by multiple persons to tension a large-sized floor support plate, the first rod member 100 can be positioned at the first position, so that the distance between the two hand-held ends can be pulled apart, thereby providing sufficient operation space for multiple workers. When the tensioning assembly 10 is operated by a single person to tension the small-sized floor support plate, the first rod member 100 can be positioned at the second position, so that the distance between the two handheld ends can be shortened to facilitate the operation by the single person. Only the first rod piece 100 needs to be rotated when the first position and the second position need to be switched, and the operation is convenient and fast, so the tensioning assembly 10 of the scheme is suitable for the tensioning scenes of the floor support plates with various specifications, and the installation quality of the floor support plates can be ensured.

In some embodiments, referring to fig. 6, the second handheld end 210 of the second lever 200 can be proximate to the first handheld end 110 of the first lever 100 in the first direction X, such that the second tensioning end 220 is proximate to the first tensioning end 120 in the first direction X.

Since the second tensioning end 220 may abut the second floor support plate, the first tensioning end 120 may abut the first floor support plate. It will be appreciated that the second floor support plate may move relative to the first floor support plate in the first direction X as the second tensioning end 220 approaches the first tensioning end 120 in the first direction X. In other words, the tensioning assembly 10 can adjust the position of the second floor support plate along the first direction X relative to the first floor support plate, that is, the tensioning assembly 10 can adjust the alignment degree of the adjacent floor support plates along the first direction X, so that the installation accuracy of the floor support plates is further improved, and the installation quality of the floor support plates is ensured.

In some embodiments, the first bending portion protrudes from the first rod 100 in a direction away from the second rod 200, and the second bending portion protrudes from the second rod 200 in a direction away from the first rod 100. The first bending part and the second bending part are oppositely arranged along the second direction Y. The first bending portion and the second bending portion are disposed, so that the first hand-held end 110 has a first distance and a second distance after rotating along the axis direction Z of the first hand-held end 210, that is, sufficient operation space is provided when the tensioning assembly 10 needs multiple operations, and the first hand-held end 110 and the second hand-held end 210 are pulled to be closely spaced when operated by a single person, thereby facilitating the operation.

Referring to fig. 1 to 7, the tensioning assembly 10 includes a base 140, and the base 140 is sleeved on the outer circumference of the first tensioning end 120. It will be appreciated that a sleeve may be added to the interior of the base 140 to connect with the body portion of the first lever 100. The base 140 includes first and second baffles 141 and 142 and a third baffle 143 disposed opposite to each other along the first direction X. The third baffle 143 is connected to the first baffle 141 and the second baffle 142 along two ends of the first direction X, respectively. The third baffle 143 is disposed on a side of the first rod 100 facing away from the second rod 200. The base 140 is capable of rotating the first lever 100 relative to the second lever 200, facilitating switching of the first lever 100 between the first position and the second position.

It will be appreciated that the interior of the base 140, i.e., the sleeve, may be threaded and the outer circumference of the first tensioning end 120 may be threaded to facilitate rotation of the first lever 100 within the base 140.

In some embodiments, the inside of the base 140 may be repair welded with a steel plate, thereby improving the connection strength of the base 140 and the link 240. In other embodiments, a gasket may be added to the connection between the link 240 and the base 140. Specifically, the thickness of the spacer may be 0.8mm to 1.2mm. Illustratively, the spacer may take the form of 0.8mm, 0.9mm, 1.1mm, 1.2mm, or the like.

Referring to fig. 1, 2, 5 and 7, the base 140 includes a first mounting hole 144 penetrating the first and second shutters 141 and 142 in the first direction X. The second lever 200 includes a link 240 and a second mounting hole 241, referring to fig. 7. The connecting rod 240 extends out of the second rod 200 along the first direction X and toward the first rod 100, and the second mounting hole 241 is provided at an end of the connecting rod 240 facing away from the second rod 200.

The tensioning assembly 10 includes a rotating shaft 300, where the rotating shaft 300 penetrates through the first mounting hole 144 and the second mounting hole 241 to connect the first rod 100 and the second rod 200, so that the second handheld end 210 is close to the first handheld end 110 along the second direction Y. In other words, the shaft 300 is inserted through the first mounting hole 144 and the second mounting hole 241 to enable the first rod 100 to rotate relative to the second rod 200, so as to achieve a corresponding tensioning function. It will be appreciated that the connection of the link 240 to the first lever 100 may be butter so that the first lever 100 can rotate more smoothly with respect to the second lever 200.

It should be noted that, on the basis of ensuring that the first tensioning end 120 and the second tensioning end 220 have sufficient displacement, that is, on the basis of enabling the floor support plate to be tensioned, the first connecting hole may be biased toward the first tensioning end 120 as much as possible, which is equivalent to enabling the connection fulcrum of the first rod 100 and the second rod 200 to be as close to the first tensioning end 120 as possible, thereby reducing the force application requirement of the handheld end and facilitating the operation of staff.

Referring to fig. 1 to 7, the first mounting hole 144 extends in the axis direction Z. The axis direction Z is perpendicular to both the first direction X and the second direction Y. The tensioning assembly 10 includes a plurality of spacer blocks 145, the spacer blocks 145 being disposed in the first mounting holes 144. In some embodiments, the outer profile of the pad 145 may be configured as a crescent. In other embodiments, the exterior profile of the spacer 145 may be configured as a rectangular shape with grooves. In other implementations, the exterior profile of the pad 145 may be semi-circular. Some embodiments of the utility model take the crescent-shaped spacer 145 as an example.

Referring to fig. 4 and 5, the plurality of pads 145 are stacked in the axis direction Z such that the second tensioning end 220 can approach the first tensioning end 120 in the first direction X, i.e., displacement of the second deck relative to the first deck in the first direction X is achieved, thereby adjusting installation accuracy between adjacent decks. The installation quality of the floor support plate is guaranteed, and casting slurry leakage is prevented.

It can be appreciated that, in order to make the connection of the rotating shaft 300 stable during the process that the second tensioning end 220 approaches the first tensioning end 120 along the first direction X, the two end portions of the rotating shaft 300 may respectively exceed the outer side portions of the first baffle 141 and the second baffle 142, i.e. the length of the rotating shaft 300 along the first direction X is greater than the maximum length of the third baffle 143 along the first direction X.

In some embodiments, the first tensioning end 120 is provided with a first angle that abuts the first floor support plate. The contact area of the first rod piece 100 and the floor support plate can be increased by arranging the first angle steel, so that point-shaped concentrated load in the tensioning and biting process of the first rod piece 100 and the floor support plate is converted into uniform load, and the problem of slurry leakage in subsequent floor pouring caused by uneven tensioning of point-shaped stress in the paving process of the floor support plate is effectively solved.

Additionally, the second tensioning end 220 is provided with a second angle, which abuts the second floor support plate. The second angle steel has similar effects to the first angle steel and will not be described again here.

In some embodiments, the first rod 100 extends a length L1,0.8 m.ltoreq.L1.ltoreq.1.2 m. Illustratively, the first lever 100 may take the form of 0.8m, 0.85m, 0.9m, 1m, 1.2m, or the like. The extension length of the first rod 100 herein refers to the extension height of the entire first rod 100 along the axis direction Z.

Additionally, the second pin 200 has an extension length L2,0.8 m.ltoreq.L2.ltoreq.1.2 m. Illustratively, the second lever 200 may take the form of 0.8m, 0.84m, 0.95m, 1m, 1.2m, or the like. The extension length of the second rod 200 herein refers to the extension height of the entire second rod 200 along the axis direction Z.

The length of the first rod 100 and the second rod 200 are set to meet the height and the operation habit of the related operator, so that the related operator can more comfortably complete the operations such as tensioning.

In some embodiments, the extension length of the first lever 100 and the extension length of the second lever 200 may be equal. Is convenient for the user to operate.

Additionally, the first rod 100 may have a cylindrical cross section in the first direction X, and in particular, the first rod 100 may be a steel pipe. Similarly, the second rod 200 has a cylindrical cross section in the first direction X, and in particular, the first rod 100 may be a steel pipe. The steel pipe is convenient for users to hold and is convenient to acquire on the construction site, the utilization rate of materials can be improved, and the construction cost is reduced. Specifically, the size of the steel pipe may be selected to be phi 32mm.

In some embodiments, both the first hand-held end 110 and the second hand-held end 210 of the tensioning assembly 10 may be welded handles. In other embodiments, the first and second handheld ends 110, 210 may also be bolted together to act as a hand grip. The above arrangement is convenient for the operator concerned to hold and for the worker to operate the tensioning assembly 10.

The method of operation of the tensioner assembly 10 in some embodiments is described in detail below.

And placing the steel bar truss plate (the second floor support plate) to be installed at a designated position to ensure the position correspondence of the connecting port.

The first and second tensioning ends 120, 220 of the tensioning assembly 10 are respectively abutted against the bottom rebars of the first and second deck plates (the installed rebar truss plates). When two or more persons are required to operate (when the floor support plate is of a large size and heavy mass), the first hand-held end 110 is spaced a first distance (in a first position) from the second hand-held end 210, see fig. 1. The first hand-held end 110 is close to the second hand-held end 210 along the second direction Y by applying force, so that the first floor support plate is close to and abuts against the second floor support to complete tensioning, and then the steel bars on the floor support plate and the upper surface of the steel beam are electrically welded and reinforced, so that paving is completed. When a single person is required to operate, the first handheld end 110 is spaced a second distance (in a second position) from the second handheld end 210, see fig. 3. The first hand-held end 110 is forced in the second direction Y toward the second hand-held end 210, and then tensioned and welded to complete the application.

It should be noted that, when the first floor support plate and the second floor support plate are shifted in the first direction X, the second handheld end 210 may be forced to approach the first handheld end 110 along the first direction X, so that the second tensioning end 220 approaches the first tensioning end 120 along the first direction X. Similarly, force may also be applied to move the second handheld end 210 away from the first handheld end 110 in the first direction X, thereby moving the second tensioning end 220 away from the first tensioning end 120 in the first direction X. The mode can realize the position adjustment of the first floor support plate and the second floor support plate along the first direction X, ensure the assembly precision of the first floor support plate and the second floor support plate and prevent the pouring slurry leakage of the floor support plates.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
