Abstract
Description
Technical Field
[0001] The present application relates to the field of material fittings for formwork engineering in building construction, and more specifically to a hybrid prefabricated beam and floor formwork system structure. Background Art
[0002] Since the traditional aluminum formwork (metal formwork) began to be popularized and used in the standard floors of residential buildings in China in 2008, because it can better meet the quality requirements of the concrete structures of beams, slabs, walls and columns without plastering, and most of the node structures such as doors and windows that originally required secondary pouring can be poured at one time and meet the quality requirements without plastering, so up to now, aluminum formwork has been used for pouring in many standard floors above 25 floors.
[0003] Due to the requirement of using an all-aluminum structure, more than 300 strictly numbered modular aluminum formworks were initially introduced. The pre-assembly in the factory and the first assembly on the project each took more than 15 days. With gradual optimization and improvement, the number of modular categories of aluminum formworks has now been reduced to more than 200. Also, in the factory, computer software pre-assembly is used to replace on-site pre-assembly of aluminum formworks, and the first assembly time of aluminum formworks on the construction site has been reduced to about 7 days. However, until now, due to the use of an all-aluminum (metal) prefabricated formwork structure and an independent steel support and early removal and dot support structure, it is necessary to install, remove, and transport and install strictly according to the formwork number. In the construction of standard floors above the 25th floor, as long as the workers are not replaced, the construction speed and so on can be guaranteed; if the workers are replaced, it is only necessary to construct strictly according to the number. The impact on the construction speed is only in the 2 - 5 floors during the familiarization stage, and the construction speed can basically be guaranteed; but in the construction of non-standard floors such as basements and podium buildings, due to the changes in the structure, design dimensions, positions, etc. of each construction section, when the formwork is removed and turned over to the next construction section, in order to strictly turn over according to the design number and replace the newly added structural formwork, it is necessary for the technical personnel of the factory to closely cooperate with the on-site management personnel, piecework team leaders, piecework workers, etc. of the carpentry team to carry out the turnover construction better, that is, each turnover installation is equivalent to the first assembly. Moreover, due to the current common savage formwork removal, and the fact that the formwork removal, transportation, and installation workers generally belong to three different types of work in most cases and other comprehensive factors, the difficulty and cost of cleaning, packing according to the number, designing, managing, transporting, and installing after the formwork removal of the non-standard structural floor are high and difficult to reduce, and it is also very difficult to improve the installation speed. During each concrete pouring process, the concrete slurry is very easy to leak out from the joint gaps or the increasingly deep and large scratches caused by multiple formwork removals. Since it is difficult to clean the concrete slurry thoroughly during turnover use, the concrete slurry will gradually accumulate on the formwork surface, making the formwork thicker and larger. After 15 times of turnover use, the structural dimensions of most formworks will become larger and it is difficult to adjust them to the designed structural dimensions, resulting in more and more difficult formwork installation. At the same time, in order to save material costs, the formwork is generally not directly replaced, so more and more grinding and repair costs need to be paid to achieve the quality of plaster-free
[0004] How to improve the product structure, reduce the usage difficulty and usage cost, and at the same time ensure or even improve the project quality is the key research direction of each enterprise. Summary of the Invention

[0043] Embodiment 1
[0044] As Figure 1 , 2As shown in the figure, a hybrid prefabricated beam and floor formwork system structure is arranged on the support vertical rod system structure 1000 and is connected to the wall column formwork system structure at the periphery, and includes a beam formwork system structure 2000 and a floor slab formwork system structure 3000 that are connected to each other; the beam formwork system structure 2000 and the floor slab formwork system structure 3000 are arranged at intervals.
[0045] As Figure 3 shown in the figure, the beam formwork system structure 2000 is composed of a beam bottom formwork system 2100 and one or two beam side formwork systems 2200 connected to the beam bottom formwork system 2100 through corner L-shaped bars 2300; the beam bottom formwork system 2100 is perpendicular to the beam side formwork system 2200.
[0046] The corner L-shaped bar is the commonly used L-shaped angle steel in the art, and it is fixed to the adjacent structure through a pin and a washer. This structure is the prior art in the art, and those skilled in the art can complete its setting and use without creative labor, so it will not be elaborated here.
[0047] Generally, a beam is composed of a beam bottom formwork system and two beam side formwork systems arranged on both sides of it. However, when sunken pouring is required in positions such as bathrooms, one side of the beam bottom formwork system is connected to the beam side formwork system, and the other side is directly connected to the floor slab formwork system structure.
[0048] As Figure 4 shown in the figure, the beam bottom formwork system 2100 is composed of a beam bottom standard prefabricated formwork structure composed of several successively connected beam bottom standard prefabricated formworks 2110, and two beam bottom non-standard formworks 2120 with the same size respectively arranged at the front and rear ends of the standard formwork structure.
[0049] The beam bottom standard prefabricated formwork, the beam side standard prefabricated formwork, and the floor slab standard prefabricated formwork are all prior art. Generally, they are divided into aluminum formworks, steel frame formworks, high-strength steel formworks, plastic steel formworks, etc. Pin holes are arranged around their frames. Those skilled in the art can complete their setting and use without creative labor, so it will not be elaborated here.
[0050] Since the beam is mainly for support and load-bearing during actual use, two beam bottom non-standard formworks with the same size are respectively arranged at the front and rear of the standard formwork structure in this application. The main purposes are as follows: First, to make the overall force of the beam more uniform during pouring; Second, to make the forces borne by the two beam bottom non-standard formworks basically the same during pouring, so as to effectively avoid different deformations caused by different forces on them; Third, to make the overall force of the formed beam more uniform, and effectively avoid the situation of uneven force of the beam caused by deformation during pouring.
[0051] As Figure 5As shown in the figure, the non-standard formwork 2120 at the bottom of the beam is composed of a first wooden board main body 2121, first L-shaped side strips 2122 symmetrically arranged on the left and right side edges of the back of the first wooden board main body 2121, and first L-shaped connecting heads 2123 symmetrically arranged on the front and back side edges of the back of the first wooden board main body 2121 and located between the two first L-shaped side strips 2122; a number of pin holes are provided on both the first L-shaped side strips 2122 and the first L-shaped connecting heads 2123; a reinforcing piece is respectively provided at both ends of the first L-shaped side strips 2122 and the first L-shaped connecting heads 2123.
[0052] The non-standard formwork 2120 at the bottom of the beam and the standard prefabricated formwork 2110 at the bottom of the beam are fixed together by pins and washers that simultaneously penetrate the pin holes on the first L-shaped connecting heads 2123 and the pin holes on the standard prefabricated formwork 2110 at the bottom of the beam.
[0053] The non-standard formwork at the bottom of the beam and the corner L-bar are fixed together by pins and washers that simultaneously penetrate the pin holes on the first L-shaped side strips and the pin holes on the corner L-bar.
[0054] The first L-shaped side strip, the first L-shaped connecting head, the second L-shaped side strip, the second L-shaped connecting head, the L-shaped hinge, and the third L-shaped connecting head are respectively fixed on the first wooden board main body, the second wooden board main body, and the third wooden board main body by screws or screw assemblies. The setting method is a conventional means in the art, and those skilled in the art can complete its setting without creative labor, so it will not be elaborated here.
[0055] As Figure 6 shown in the figure, the beam side formwork system 2200 is composed of several columns of beam side standard formwork structures each consisting of at least one beam side standard prefabricated formwork 2210, beam side non-standard formworks 2220 arranged between any two columns of beam side standard formwork structures, and corner connection structures arranged above the beam side standard formwork structures and the beam side non-standard formworks 2220; the corner connection structures are composed of several sequentially connected C-shaped grooves 2230 and non-standard L-shaped blocks 2240 arranged between any two adjacent C-shaped grooves 2230.
[0056] As Figure 7 shown in the figure, the beam side non-standard formwork 2220 is composed of a second wooden board main body 2221, second L-shaped side strips 2222 symmetrically arranged on the left and right side edges of the back of the second wooden board main body 2221, and second L-shaped connecting heads 2223 symmetrically arranged on the upper and lower side edges of the back of the second wooden board main body 2221 and located between the two second L-shaped side strips 2222; a number of pin holes are provided on both the second L-shaped side strips 2222 and the second L-shaped connecting heads 2223; a reinforcing piece is respectively provided at both ends of the second L-shaped side strips 2222 and the second L-shaped connecting heads 2223.
[0057] The non-standard formwork 2220 on the side of the beam and the standard prefabricated formwork 2210 on the side of the beam are fixed together by a pin and a washer that simultaneously penetrate the pin holes on the second L-shaped side strip 2222 and the pin holes on the standard prefabricated formwork 2210 on the side of the beam.
[0058] As Figure 8 shown, the C-shaped groove 2230 is composed of an L-shaped back plate 2231, two mutually parallel end L-shaped plates 2232 provided at both ends of the L-shaped back plate 2231, two connecting pieces 2233 respectively provided on the upper end face and the front end face of the L-shaped back plate 2231 and fixed to the upper end faces and the front end faces of the two end L-shaped plates 2232, and a plurality of reinforcing L-shaped plates 2234 that are parallel to the end L-shaped plates 2232 and provided on the L-shaped back plate 2231; pin holes are provided on both the end L-shaped plates 2232 and the connecting pieces 2233.
[0059] The C-shaped groove is an existing technology in the art, and those skilled in the art can complete its setting and use without creative labor, so it will not be elaborated here.
[0060] As Figure 9 shown, the non-standard L-shaped block 2240 is composed of an L-shaped wooden board 2241, two L-shaped fixing pieces 2242 provided at both ends of the L-shaped wooden board 2241 and respectively fixed to the L-shaped wooden board 2241 by screws or screw assemblies, two end connecting pieces 2243 respectively vertically provided on the L-shaped fixing pieces 2242 and flush with the upper end and the front edge of the L-shaped wooden board 2241, and side reinforcing connecting pieces 2244 that are flush with both ends of the L-shaped wooden board 2241 and fixed together with the L-shaped fixing pieces 2242 and the end connecting pieces 2243; pin holes are provided on both the end connecting pieces 2243 and the side reinforcing connecting pieces 2244;
[0061] The non-standard L-shaped block 2240 and the C-shaped groove 2230 are fixed together by a pin and a washer that simultaneously penetrate the pin slots on the end L-shaped plate 2232 and the pin slots on the side reinforcing connecting piece 2244.
[0062] As Figure 10 shown, the floor slab formwork system structure 3000 is composed of a number of floor slab standard formwork structures each consisting of at least one floor slab standard prefabricated formwork 3010, a non-standard vertical formwork structure consisting of at least one floor slab non-standard formwork 3020 provided between any two columns of floor slab standard formwork structures, and a non-standard vertical formwork structure consisting of at least one floor slab non-standard formwork 3020 provided in a row at the front or rear of the floor slab standard formwork structure and the non-standard vertical formwork structure.
[0063] As Figure 11As shown, the non-standard floor slab formwork 3020 consists of a third wooden board main body 3021, two reinforcing square tubes 3023 arranged on the long edge of the back of the third wooden board main body 3021, several L-shaped hinges 3022 arranged in rows on the back of the third wooden board main body 3021 and attached to the reinforcing square tubes 3023, and a third L-shaped connector 3024 arranged on the short edge of the back of the third wooden board main body 3021 and located between the two reinforcing square tubes 3023;
[0064] In the non-standard floor slab formwork, the use of a reinforcing square tube in combination with an L-shaped hinge replaces the L-shaped edge strip. This not only effectively improves the support performance through the reinforcing square tube but also effectively reduces the overall weight through the L-shaped hinge.
[0065] When the width of the third wooden board main body exceeds 250 mm, a reinforcing square tube spanning its length needs to be provided in the middle of its back to improve the bearing capacity of the non-standard floor slab formwork.
[0066] The reinforcing square tubes 3023, L-shaped hinges 3022, and the third L-shaped connector 3024 are all provided with pin holes; both ends of the third L-shaped connector 3024 are respectively provided with a reinforcing piece;
[0067] The non-standard floor slab formwork 3020 and the standard prefabricated floor slab formwork 3010 are fixed together by pins and washers that simultaneously pass through the pin holes on the L-shaped hinges 3022, the pin holes on the reinforcing square tubes 3023, and the pin holes on the standard prefabricated floor slab formwork 3010.
[0068] The non-standard beam bottom formwork and the non-standard floor slab formwork are fixed together by pins and washers that simultaneously pass through the pin holes on the first L-shaped edge strip and the pin holes on the third L-shaped connector or the pin holes on the L-shaped hinges and the pin holes on the reinforcing square tubes. The non-standard beam bottom formwork and the standard prefabricated floor slab formwork are fixed together by pins and washers that simultaneously pass through the pin holes on the first L-shaped edge strip and the pin holes on the standard prefabricated floor slab formwork. During construction, an L-shaped edge strip can also be used to replace the combination of the reinforcing square tube and the L-shaped hinge, but it is necessary to ensure that the L-shaped edge strip has not undergone any deformation before use to ensure that the L-shaped edge strip can provide sufficient support force, thereby ensuring the safety and quality of the construction.
[0069] The above-mentioned various components are all connected and fixed by pins and washers. The pins and washers are prior art in this field and have been maturely used in this field. Those skilled in the art can complete the use of pins and washers without creative labor and will not be elaborated here.
[0070] In addition, to ensure the accuracy of the fit, the spacing between multiple pin holes at the same position on the same component is set to be a multiple of 50 mm, which not only ensures the fit effect between non-standard structures but also ensures the fit effect between non-standard structures and standard structures.
[0071] It should be noted that all the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.
[0072] In addition, the above specific embodiments are exemplary.
