Description

Technical Field

[0001] This application relates to the field of material fittings for formwork engineering in building construction, and more specifically, to a combined prefabricated floor formwork structure system. Background Art

[0002] In the prior art, before pouring the floor slab, it is necessary to first build a floor formwork structure for bearing and supporting concrete. To ensure the stability of the floor formwork, it is necessary to build a support frame for supporting the floor formwork below the floor formwork structure. The support frame is composed of several vertically arranged support columns, cross braces erected between the support columns, and plate top supports inserted at the top of the support columns. In most traditional wooden formwork floor formwork structures today, a U-shaped top support is first inserted at the top of the support column and abutted against the lower part of the Φ48 round tube or I-beam steel main keel, and then the main keel is supported by the U-shaped top support tray, and several main keels support several wooden or ordinary iron secondary keels perpendicular to the main keel to support the lower part of the floor formwork in multiple places. Moreover, the distance between the U-shaped top support surface and the nearest cross brace at the lower end cannot exceed 600 mm, that is, the free end does not exceed 600 mm. Therefore, this support method does not allow the early removal of the main and secondary floor keels and the floor formwork.

[0003] In some current construction sites, traditional foreign wooden formwork early removal top supports are used. However, the early removal heads all extend to the floor concrete or the early removal strip floor formwork through flat top supports with various shapes. The main keels of the board are placed on the main keel trays with various shapes. The maximum distance between the early removal head surface of the board top support and the nearest cross brace at the lower end is about 750 mm, and the maximum distance between the main keel tray surface of the board and the nearest cross brace at the lower end is within 600 mm.

[0004] In the actual process of traditional wooden formwork early removal construction, if all the main and secondary keels are directly removed, the support structure of the floor formwork will only have flat early removal heads left, and its support force on the floor formwork or concrete structure is limited to the contact surface. Looking at the entire floor slab, it is equivalent to supporting it through several points, so it is very easy for the support force to be too concentrated, resulting in a large number of hidden cracks inside the floor slab, thereby reducing the overall service life of the floor slab. After years of research by our company, it is found that when early removing the secondary keels, if some secondary keels are removed while retaining the secondary keels that are always not separated from the floor formwork at the top of the board top support, the existing point support can be adjusted to line support, thereby greatly reducing the generation amount of hidden cracks, better ensuring the quality of the floor slab, and greatly extending the service life of the floor slab.

[0035] Embodiment 1

[0036] As Figure 1 shown, a combined prefabricated floor formwork structure system includes a support frame composed of several support vertical poles 1000, a beam support structure 2000 arranged on the support frame, a floor slab support structure 3000 arranged on the support frame, a beam formwork structure composed of several beam formworks 4000 arranged on the beam support structure 2000, and a floor formwork structure composed of several floor formworks 5000 arranged on the floor slab support structure 3000 and connected to the beam formwork structure; the beam formwork 4000 further includes a beam bottom formwork and a beam side formwork.

[0037] The beam formwork is a prior art. The beam formwork can be a beam formwork built with pure wood formwork, or a beam formwork built with pure aluminum formwork, or a beam formwork built with a mixture of wood formwork and aluminum formwork. Those skilled in the art can complete the setting of the beam formwork without creative labor, so it will not be elaborated here.

[0038] As Figure 6 shown, the floor formwork 5000 is composed of a wood formwork main body 5100 with a rectangular front surface, and several L-shaped hinges 5200 arranged around the back edge of the wood formwork main body 5100; hinge connection holes are provided on the vertical surfaces of the L-shaped hinges 5200.

[0039] The wood formwork main body can be made of wood materials, or can be made of non-metallic materials such as bamboo and plastic. The reason for choosing wood materials is that the total cost of production and use is the lowest.

[0040] As shown Figure 2 in the figure, the floor slab support structure 3000 includes a main floor joist 3100 disposed on the support vertical pole 1000, a square secondary joist 3200 that is connected end to end in groups and laid side by side on the main floor joist 3100 and abuts against the lower side of the floor formwork 5000, and a supplementary secondary joist 3300 that is connected end to end and laid on the main floor joist 3100 and abuts against the lower side of the floor formwork 5000; a supplementary secondary joist connection hole that vertically penetrates the supplementary secondary joist 3300 is provided on the supplementary secondary joist 3300.

[0041] The function of the supplementary secondary joist is that when the laying spacing is too small and the setting of the square secondary joist cannot be accommodated, the supplementary secondary joist is used to replace the square secondary joist for laying. By laying the supplementary secondary joist, the support effect can be effectively guaranteed, so that the forces on each square secondary joist and the supplementary secondary joist during pouring can be more balanced.

[0042] As shown Figure 4 in the figure, the square secondary joist 3200 is composed of a secondary joist square tube part 3210 and a spacer part 3220 provided on the secondary joist square tube part 3210;

[0043] The secondary joist square tube part 3210 is composed of two or three square tube bodies 3211 arranged in parallel with each other and a number of joist connection holes 3212 that vertically penetrate the square tube body 3211;

[0044] The spacer part 3220 is composed of a spacer sleeve 3221 disposed between any two adjacent square tube bodies 3211 and a connecting bolt 3222 that simultaneously penetrates the two square tube bodies 3211 and the spacer sleeve 3221.

[0045] As shown Figure 5 in the figure, a set of connection heads 3230 are provided between any two square tube bodies 3211 connected end to end. The connection head 3230 is composed of a spacer block 3231, two insertion square tubes 3232 provided at the front and rear ends of the spacer block 3231 and having dimensions matching those of the square tube body 3211, and a connection hole 3233 that vertically penetrates the insertion square tube 3232 and matches the joist connection hole 3212; two connection holes 3233 are provided on the insertion square tube 3232, and the secondary square tube body 3211 and the connection head 3230 are fixed together by a pin that simultaneously penetrates the joist connection hole 3212 and the connection hole 3233 and a washer that cooperates with the pin.

[0046] A rubber plug 3213 is further provided at one end of the square tube body 3211 where the connection head 3230 is not fixed.

[0047] Any two consecutively connected floor formworks 5000 in the floor formwork structure are fixed together by a pin passing through two corresponding hinge connection holes and a washer cooperating with the pin; a square tube body 3211 is arranged between two rows of L-shaped hinges 5200 on the contacting edges of any two horizontally connected floor formworks 5000 in the floor formwork structure, and the two floor formworks 5000 and the square tube body 3211 are fixed together by a pin passing through the hinge connection hole and the keel connection hole 3212 and a washer cooperating with the pin.

[0048] If a supplementary secondary keel is exactly arranged at the joint position of two consecutively connected floor formworks, the two floor formworks and the supplementary secondary keel are connected in the above manner.

[0049] Through the above setting method, a non-early removal structure system can be set up. The left and right joints of the floor formwork are fixed on any square tube body of the square secondary keel, which can not only effectively complete the fixation, but also reinforce and support the joint through the square tube body, avoiding the deformation of the joint of the floor formwork due to the pressure of concrete during pouring, and effectively improving the use effect of the product. Since this structure is a non-early removal structure system, when selecting the floor formwork, floor formworks with a relatively wide left and right width can be selected as much as possible, which can effectively reduce the construction difficulty and better ensure the construction efficiency and stability.

[0050] Embodiment 2

[0051] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the floor slab support structure 3000 further includes a strip-shaped support belt secondary keel 3400 fixed on the support vertical rod 1000, laid on the main slab keel 3100 after being connected end to end and abutted against the lower side of the floor formwork 5000; a strip-shaped support belt connection hole vertically penetrating the strip-shaped support belt secondary keel 3400 is arranged on the strip-shaped support belt secondary keel 3400.

[0052] The strip-shaped support belt secondary keel 3400 and the support vertical rod 1000 are fixed together by a pin passing through the strip-shaped support belt connection hole and the top of the support vertical rod 1000 and a washer cooperating with the pin.

[0053] Any two consecutively connected floor formworks 5000 in the floor formwork structure are fixed together by a bolt passing through two corresponding hinge connection holes and a washer cooperating with the bolt; between two rows of L-shaped hinges 5200 on the contacting edges of any two left-and-right connected floor formworks 5000 in the floor formwork structure, a square tube body 3211 or a supplementary secondary keel 3300 is provided, and the two floor formworks 5000 and the square tube body 3211 or the supplementary secondary keel 3300 are fixed together by a bolt passing through the hinge connection hole and the keel connection hole 3212 or the supplementary secondary keel connection hole and a washer cooperating with the bolt.

[0054] Through the above setting method, an early demolition structure system can be set up. The left-and-right joints of the floor formwork are fixed on any square tube body of the supplementary secondary keel or the square box secondary keel, which can not only effectively complete the fixation, but also reinforce and support the joints through the supplementary secondary keel or the square tube body, avoiding deformation of the joints of the floor formwork due to the pressure of concrete during pouring, and effectively improving the use effect of the product.

[0055] Since this structure is an early demolition structure system, when selecting the floor formwork that needs to be demolished early, it is necessary to ensure that the left-and-right width of the floor formwork that needs to be demolished early is less than the spacing of the support vertical poles below it, so as to ensure that it can be demolished early smoothly.

[0056] 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.

[0057] In addition, the above specific embodiments are exemplary. Those skilled in the art can come up with various solutions inspired by the disclosure of the present invention, and these solutions also belong to the disclosure scope of the present invention and fall within the protection scope of the present invention. Those skilled in the art should understand that the specification and drawings of the present invention are illustrative and do not constitute a limitation on the claims. The protection scope of the present invention is defined by the claims and their equivalents.
