Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a positioning and guiding tooling and a tooling assembly. Background Technique

[0002] With the increasing development of modern industrial technology, houses can be manufactured and produced in batches like machines, and construction workers only need to transport the prefabricated house components to the designated positions at the construction site for assembly. Based on the advantages of fast construction speed and low production cost of prefabricated buildings, it has been rapidly promoted globally and is highly favored.

[0003] Currently, the development of prefabricated buildings in China is still in its initial stage, and the entire production process and industrial chain are not yet perfect. At present, various double-sided composite walls in prefabricated buildings use steel bar lapping. During the hoisting process, by sleeving the hollow part of the prefabricated double-sided composite wall component onto the U-shaped steel bars protruding from the lower layer, the splicing and fixing of the components can be achieved, and finally a wall is formed. However, in the actual construction process, due to the large dimensional deviation and position deviation of the protruding steel bars, and the small gap formed with the components, which is not easy to control, it is easy to cause the components to be unable to be smoothly sleeved onto the U-shaped steel bars, greatly increasing the construction difficulty of the on-site workers. Generally, a 50-mm construction post-cast strip is reserved at the bottom of the component and supported by cushion blocks, the horizontal position of the bottom surface is adjusted by the lower inclined support, and the verticality is adjusted by the upper inclined support. The disadvantage of such a setting is that it will directly lead to an increase in the operation difficulty and a decrease in the construction efficiency during the on-site construction process.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been an urgent problem for ordinary technical personnel in this field. Summary of the Invention

Detailed implementation manners

[0056] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained.

[0057] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some drawings, for components with the same structure or function, only one of them is schematically shown, or only one of them is marked. In this document, "one" not only means "only this one", but also means the situation of "more than one".

[0058] It should also be further understood that the term "and / or" used in the specification and the appended claims of the present application refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0059] In this text, it should be noted that unless otherwise clearly stipulated and defined, the terms "installation", "connection", and "linkage" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0061] According to a specific embodiment provided by the present invention, as Figures 1 to 3 shown, the present invention provides a positioning and guiding tooling in the first aspect, which is used to guide the precast composite wall 400 to be sleeved into the protruding steel bars 300 of the lower layer. A row of templates 200 are pre-installed on both sides of the protruding steel bars 300, and a working station 210 for placing the bottom of the precast composite wall 400 is formed between the two rows of templates 200. The positioning and guiding tooling includes two tooling components 100, which are respectively arranged on the two rows of templates 200 and are correspondingly arranged. Each tooling component 100 includes a horizontal fixing member 1 and a vertical guiding member detachably assembled on the horizontal fixing member 1. The horizontal fixing member 1 is butted against the protruding steel bars 300 to fix the vertical guiding member and the template 200 to the side of the protruding steel bars 300. Among them, the vertical guiding member has a guiding portion 23, and the two guiding portions 23 are symmetrically arranged above the working station 210 and are jointly used to guide the precast composite wall 400 into the interior of the working station 210.

[0062] In this embodiment, the horizontal fixing member 1 is butted against the protruding steel bars 300. With the support of the protruding steel bars 300, the horizontal fixing member 1 can firmly fix the vertical guiding member and the template 200 to the side of the protruding steel bars 300. Thus, when the precast composite wall 400 is sleeved into the protruding steel bars 300 of the lower layer, the guiding portions 23 of the two vertical guiding members can be jointly used to guide both sides of the bottom of the precast composite wall 400 into the interior of the working station 210, ensuring that the precast composite wall 400 will not be misaligned during the installation process, achieving precise positioning of the precast composite wall 400, greatly reducing the difficulty of on-site construction for workers and improving the construction efficiency. And under the support of the horizontal fixing member 1 and the protruding steel bars 300, even under the extrusion of the precast composite wall 400, the two guiding portions 23 will not easily shift or be misaligned.

[0063] Of course, in the second aspect, the present invention also provides a tooling assembly, which may specifically include two rows of templates 200 pre-mounted on both sides of the protruding steel bars 300 and at least two positioning and guiding toolings as provided in the first aspect of the present invention. Among them, at least two positioning and guiding toolings are arranged at intervals along the length direction of the working station formed by the two rows of templates 200.

[0064] Specifically, in this embodiment, the number of the positioning and guiding toolings is set to at least two because during the actual assembly of the precast composite wall 400, it is necessary to perform limit guiding on both ends of the bottom length direction of the precast composite wall 400, so as to ensure that the precast composite wall 400 can accurately and smoothly enter the working station 210 to accurately cooperate with the protruding steel bars 300 of the lower layer. If only one positioning and guiding tooling is provided, it can only act on one end of the bottom of the precast composite wall 400, which is very likely to cause the other end of the precast composite wall 400 to shake and tilt during the assembly process, thus affecting the assembly effect.

[0065] It is worth mentioning that in this embodiment, based on the different sizes of the precast composite walls 400 required at the actual construction site, in order to expand the application scenarios of this tooling assembly, each row of templates 200 can be formed by sequentially splicing several templates 200 end to end. As for the number of templates 200 required, it can be flexibly selected according to the transverse length of the precast composite wall 400, and no limitation is made here. In this way, by docking the transverse fixing member 1 to the protruding steel bars 300, the vertical guiding member and the template 200 can be firmly fixed to the side of the protruding steel bars 300, so that the templates 200 can be quickly spliced and removed on site by operating the transverse fixing member 1, which is convenient for transportation and carrying. And when a local part of the template 200 is damaged, only the template 200 corresponding to this local position needs to be replaced, which greatly saves economic and labor costs.

[0066] In this embodiment, the protruding steel bars 300 are in an inverted U shape. Each pair of oppositely arranged tooling components 100 are respectively butted against both sides of the protruding steel bars 300 through the transverse fixing members 1, so as to fix the vertical guiding member and the formwork 200 together, and are used to guide the precast composite wall 400 into the interior of the working station. It should be emphasized that since the transverse fixing member 1 acts between the protruding steel bars 300 and the formwork 200, therefore, in order to effectively avoid the interference of the transverse fixing member 1 on the precast composite wall 400 during the placement process, thus restricting its entry into the interior of the working station, it is preferable to provide a matching avoidance space at the position of the bottom of the precast composite wall 400 corresponding to each transverse fixing member 1. Through the clamping fit between the avoidance space and the transverse fixing member 1, the problem of the interference of the transverse fixing member 1 on the precast composite wall 400 can be effectively avoided. Of course, in this embodiment, the width between the two rows of formworks 200 can be specifically set according to the thickness of the precast composite wall 400, and at least it should be ensured that the contour of the protruding steel bars 300 is adapted to the hollow area inside the precast composite wall 400.

[0067] In this embodiment, referring to Figure 2 and Figure 3 , the transverse fixing member 1 of each tooling component 100 may specifically include a connecting member 12, a hook member 11, and a locking member 13. Specifically, the hook member 11 is detachably assembled at one end of the connecting member 12, and the locking member 13 is detachably assembled at the other end of the hook member 11. The hook member 11 is used to butt against the protruding steel bars 300, and the locking member 13 is used to lock the vertical guiding member and the formwork 200 together and fix them to the side of the protruding steel bars.

[0068] Specifically, referring to Figure 4 , the hook member 11 may specifically include an integrally formed hook head 111 and a first screw 112. As a preference, the hook member 11 can be made of a metal material with relatively high hardness and toughness, such as steel material, but it is not limited thereto. Further, referring to Figure 5 , the connecting member 12 may specifically include an integrally formed abutting end 121 and a second screw 122. As a preference, the connecting member 12 can also be made of steel material, but it is not limited thereto. Among them, referring to Figures 3 to 5, the abutting end 121 is preferably provided with a hollow cylindrical structure, and a threaded hole 1211 is provided on the bottom wall of the groove formed inside it. The threaded hole 1211 is preferably provided at the center position of the bottom wall, but is not limited thereto. The first screw 112 of the hook member 11 is screwed into the threaded hole 1211 to achieve the assembly with the connecting member 12. During the process of the first screw 112 being screwed into the threaded hole 1211, the abutting end 121 moves towards the hook head 111. When the first screw 112 and the part of the hook head 111 adjacent to the first screw 112 enter the inside of the abutting end 121, the abutting end 121 can be in abutting fit with the end wall of the protruding steel bar 300 to lock the hook head 111 on the protruding steel bar 300, ensuring that the hook head 111 will not fall off the protruding steel bar 300. Further, the locking member 13 is screwed and matched with the second screw 122 and acts on the vertical guiding member to assemble the vertical guiding member and the formwork 200, so as to splice a plurality of formworks 200 end to end in sequence to form a whole row structure. And at the same time, the two guiding parts 23 are symmetrically arranged above the formwork 200 to guide the precast composite wall 400 into the inside of the working station 210.

[0069] As a preference, in this embodiment, refer to Figure 8 , the vertical guiding member is a vertical guide plate 2, and the vertical guide plate 2 specifically may include an integrally formed guide plate base 21, a guide plate support portion 22 and a guiding portion 23. The guide plate base 21 may be in a square block structure, the guide plate support portion 22 may be in a square sheet structure and is vertically arranged on the guide plate base 21, and the guiding portion 23 may also be in a square sheet structure and is inclinedly arranged on the guide plate support portion 22. When the vertical guide plate 2 is spliced and locked with the formwork 200 through the locking member 13, the guiding portion 23 is inclinedly arranged towards the side opposite to the protruding steel bar 300. Of course, in this embodiment, the specific structures of the guide plate base 21, the guide plate support portion 22 and the guiding portion 23 are not limited thereto and can be flexibly set according to actual use requirements. Any structure is within the protection scope of this patent and will not be elaborated here too much.

[0070] It is worth mentioning that, in this embodiment, the included angle range formed between the guiding portion 23 and the guide plate support portion 22 is preferably greater than or equal to 120 degrees and less than or equal to 150 degrees. Such an angle setting can facilitate the precast composite wall 400 to be quickly and smoothly guided into the working station. Of course, based on the actual application scenario, other included angles may also be formed between the guiding portion 23 and the support portion, and no more restrictions are made here.

[0071] Even more worth mentioning is that, in this embodiment, the surface of the guiding portion 23 for cooperating with the precast composite wall 400 can be preferably set to be a smooth surface, and the guiding portion 23 is preferably made of a metal material with high hardness and wear resistance, so that the structural strength and service life of the guiding portion 23 can be greatly improved.

[0072] Specifically, referring to Figures 3 to 10 , the locking member 13 may include an adjusting sleeve 131, a knuckle nut 132, a buckle plate 133, and a fixing nut 134, and the guide plate support portion 22 is provided with an adjusting slide hole 221 along its longitudinal direction. Among them, the adjusting sleeve 131 may be in a hollow cylindrical structure, and its length is less than the length of the second screw 122. After the adjusting sleeve 131 is sleeved on the second screw 122, its end abuts against the abutting end 121. As a preference, in this embodiment, in order to effectively prevent the adjusting sleeve 131 from shaking radially along the second screw 122 after being sleeved on the second screw 122, a guiding slope 123 may be provided between the abutting end 121 and the second screw 122. Further, one end of the abutting end 121 facing the second screw 122 and the area corresponding to the periphery of the guiding slope 123 may form an abutting ring platform 124. In this way, when the adjusting sleeve 131 is sleeved on the second screw 122, the guiding slope 123 can be used to guide the adjusting sleeve 131 to abut against the abutting ring platform 124 of the abutting end 121, and the guiding slope 123 can ensure that the adjusting sleeve 131 will not have lateral movement after abutting against the abutting ring platform 124.

[0073] Further, in this embodiment, after the adjusting sleeve 131 abuts against the abutting ring platform 124, the knuckle nut 132 can be screwed onto the second screw 122 so that the knuckle nut 132 abuts against one end of the adjusting sleeve 131 away from the abutting end 121. Then, the guide plate support portion 22 is sleeved on the second screw 122 through the adjusting slide hole 221 and abuts against the knuckle nut 132. As a preference, referring to Figure 7 and Figure 8 , in order to improve the tightness of the butt joint between the knuckle nut 132 and the guide plate support portion 22, it is preferable to set the surface of the guide plate support portion 22 for butt joint with the knuckle nut 132 as a rough surface 222. Correspondingly, a tooth pattern 1321 may be provided on the surface of the knuckle nut 132 for butt joint with the guide plate support portion 22 for butt joint and cooperation with the rough surface 222. The specific patterns of the rough surface 222 and the tooth pattern 1321 in this embodiment are not limited, and can be flexibly set according to actual use requirements, and are all within the protection scope of this patent. Through the butt joint and cooperation of the rough surface 222 and the tooth pattern 1321 in this embodiment, the structural strength of the butt joint between the knuckle nut 132 and the guide plate support portion 22 can be greatly improved, so as to be able to play a stable supporting role for the vertical guide plate 2.

[0074] Further, in this embodiment, referring to Figure 9 and Figure 10, a jack hole 1331 may preferably be opened at the center position of the buckling plate 133, and a buckling convex portion 1332 is respectively provided on opposite sides of the upper end surface of the buckling plate 133. Specifically, after the guide plate support portion 22 is sleeved on the second screw rod 122 and abuts against the knuckle nut 132, the jack hole 1331 of the buckling plate 133 can be aligned with the second screw rod 122 and then sleeved on the second screw rod 122 in sequence. When the buckling plate 133 abuts against the guide plate support portion 22, the guide plate support portion 22 is just embedded in the gap formed between the two buckling convex portions 1332. Then, the end portions of the two templates 200 are respectively installed in the installation space 1333 formed between the two buckling convex portions 1332 and the buckling plate 133. Finally, the fixing nut 134 is screwed onto the second screw rod 122 and abuts against the buckling plate 133, so that the two adjacent templates 200 can be locked in the installation space 1333, thereby realizing the fixation of the vertical guiding member and the template 200 to the side portion of the protruding steel bar 300.

[0075] The working principle of the present invention will be specifically described below:

[0076] First, calculate the specific dimensions of the required precast composite wall 400 according to the actual requirements on site. First, carry out the measurement of the setting-out elevation, mark the position according to the height of the protruding steel bar 300, and then fix the hook head 111 on the protruding steel bar 300. Through the screwing cooperation of the abutting end 121 and the hook head 111, the abutting end 121 abuts against the end wall of the protruding steel bar 300 to lock the hook head 111 on the end wall of the protruding steel bar 300.

[0077] Further, the adjusting sleeve 131 is sleeved on the second screw rod 122. When the adjusting sleeve 131 abuts against the abutting ring platform 124 of the abutting end 121, the knuckle nut 132 is screwed onto the second screw rod 122 to make the knuckle nut 132 abut against one end of the adjusting sleeve 131 opposite to the abutting end 121, and ensure that the knuckle nut 132 is located at the position marked by the setting-out on the ground. Then, the guide plate support portion 22, the buckling plate 133, and the template 200 are sequentially sleeved on the second screw rod 122 and fixed by screwing the fixing nut 134, thereby realizing the fixation of the vertical guiding member and the template 200 to the side portion of the protruding steel bar 300. By analogy with the above process, the positioning and guiding tooling is installed at the required working position 210.

[0078] Further, during hoisting, when the precast composite wall 400 approaches the positioning and guiding tooling, its continued descent is stopped. At this time, the staff can fine-tune the position of the precast composite wall 400 to make it generally within the guiding range above the working position 210, and then slowly lower the precast composite wall 400. Under the guiding action of the two guiding portions 23, the precast composite wall 400 can quickly and smoothly enter the working position 210, and then adjust the upper inclined support to adjust the verticality of the precast composite wall 400 to complete the hoisting.

[0079] Further, when the concrete pouring is completed and reaches the form removal strength requirement, first unscrew the fixing nut 134, then sequentially disassemble the buckle plate 133, the formwork 200, and the vertical guide plate 2, and then turn the connecting member 12 to disassemble it together with the adjusting sleeve 131 and the thread nut 132 for continuous recycling. It should be noted that since the hook member 11 is fixed to the protruding steel bar 300 during the concrete forming process, the hook member 11 cannot be disassembled.

[0080] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
