Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a jack conversion device for a pitched roof formwork. Background Art

[0002] In the structural construction of multi-storey building projects with pitched roofs, in the traditional pitched roof formwork support system, the primary and secondary joists are arranged on the jacks, and then triangular wooden wedges are used to tighten the primary and secondary joists, and the primary and secondary joists are firmly tied to the jacks with binding wire.

[0003] For example, the Chinese utility model patent with the publication number CN219491704U discloses a double-curved roof primary and secondary joist installation structure. Refer to Figure 1 and Figure 3 and paragraphs

[0018] to

[0023] of the specification. A double-curved roof primary and secondary joist installation structure includes a support frame 1, a jack 2, a primary joist 3, a secondary joist 4, a triangular wedge 5, and a formwork 6. The support frame 1 includes a horizontal rod 11 and a main rod 12; the middle of the horizontal rod 11 is vertically intersecting and fixed with the middle of the main rod 12. The lower end of the main rod 12 of the support frame 1 is fixed on the ground, the lower end of the jack 2 is screwed on the top end of the support frame 1, the upper end of the jack 2 abuts against the bottom surface of the primary joist 3, the bottom surface of the secondary joist 4 is obliquely vertically intersecting and fixed with the top surface of the primary joist 3, a triangular wedge 5 is fixedly inserted between the bottom surface of the secondary joist 4 and the top surface of the primary joist 3, the formwork 6 is fixed on the top surface of the secondary joist 4, and concrete 10 is poured on the formwork 6.

[0004] In the traditional method, the wooden wedge (the triangular wedge 5 in the prior art document) is a disposable consumable material that is easy to lose and cannot be reused. The consumption of non-reusable materials results in high construction costs. Content of the Utility Model

[0005] In order to optimize the construction process of the pitched roof structure formwork support system, the purpose of the utility model is to provide a jack conversion device for a pitched roof formwork, so as to solve the technical problems of easy loss, large consumption of consumables, and high construction costs caused by the use of wooden wedges in the traditional method.

[0006] To achieve the above purpose, the utility model provides a jack conversion device for a pitched roof formwork, including a fixed bottom bracket and an adjustable jack inserted into the fixed bottom bracket. The adjustable jack is characterized in that it includes a bearing groove for supporting the primary joist. The bearing groove is a through groove, and a plug board is fixedly connected to the bottom of the bearing groove. The fixed bottom bracket includes a chassis, and a vertical groove body is fixedly connected to the chassis. A slot for the plug board to insert is arranged in the groove body; a longitudinal strip hole and a first shaft hole are opened on the plug board, and a transverse strip hole and a second shaft hole are opened on the groove body; bolts passing through the first shaft hole and the second shaft hole, and bolts passing through the longitudinal strip hole and the transverse strip hole are respectively provided.

[0007] In the traditional formwork support system for pitched roofs, the triangular wooden wedges used are disposable consumables, which are prone to loss and cannot be reused, resulting in material waste and increased construction costs. In this solution, by introducing adjustable top supports and fixed bottom supports, the combination of adjustable top supports and fixed bottom supports can be custom-adjusted in angle, flexibly adapting to the angle of supporting the main joist and meeting the construction requirements of roofs with different slopes. The traditional wooden wedge structure can be abandoned, avoiding the waste of consumables and thus reducing the construction cost.

[0008] Through the fixing method of bolts, the insertion plate can be adjusted and fixed within a certain angle range, simplifying the installation process and improving the construction efficiency.

[0009] The insertion plate in the adjustable top support and the bearing groove are of an integral structure. The insertion plate is fixed in the groove body of the fixed bottom support through bolts, forming a stable support structure. Compared with the risks of loosening and slipping of traditional wooden wedges, this device can provide a more reliable support function, reducing structural deformation and potential safety hazards.

[0010] Both the adjustable top support and the fixed bottom support are made of metal materials, which are more durable than traditional wooden wedges and can be reused multiple times, greatly extending the service life and further reducing the material cost and resource waste.

[0011] The adjustable top support can be adjusted by bolts and can adapt to the construction of roofs with different slopes and complex structures, having strong adaptability. Whether in the construction of flat roofs or pitched roofs, this device can provide effective support solutions.

[0012] Furthermore, the insertion plate is perpendicular to the groove wall of the bearing groove.

[0013] The insertion plate being perpendicular to the groove wall of the bearing groove can change the orientation of the bearing groove. Since the conversion device is integrally installed in the tray on the upper part of the adjustable screw rod, the insertion plate being perpendicular to the groove wall of the bearing groove can adapt to the original orientation of the tray without adjusting the direction of the original adjustable screw rod.

[0014] Preferably, the first shaft hole is located directly below the longitudinal strip hole, and the second shaft hole is located directly below the transverse strip hole.

[0015] It is convenient for processing, enabling the bolts to accurately penetrate the shaft holes and strip holes, effectively ensuring the stability of the insertion plate in the fixed bottom support. The position matching of the shaft holes and strip holes ensures that the insertion plate can be firmly locked after adjusting the angle, preventing displacement or loosening during use and improving the reliability and safety of the device.

[0016] Furthermore, the bolt includes a screw rod, one end of the screw rod is provided with a bolt head, the screw rod is connected with a nut through a threaded structure, and the other end of the screw rod is provided with a nut cap.

[0017] The bolt head and nut can clamp the connection between the insertion plate and the fixed base, ensuring the firmness of the structure; the nut provides additional protection for the other end of the screw rod, reducing the situation of easy loss of the nut, preventing damage caused by sharp corners, and also reducing the erosion of the external environment on the end of the screw rod.

[0018] The jack conversion device for pitched roof formwork provided by the present utility model has the following advantages:

[0019] By introducing the combined design of the adjustable jack and the fixed base, the present utility model solves the problems that the triangular wooden wedges in the traditional pitched roof formwork support system are easy to lose and cannot be reused. This device can be flexibly adapted to the construction requirements of roofs with different slopes by customizing the adjustment angle, avoiding the waste of consumable materials of the wooden wedges, thus effectively reducing the construction cost. Through bolt fixation, the insertion plate can be adjusted and fixed within a certain angle range, simplifying the installation process and improving the construction efficiency. Compared with the traditional wooden wedges, this device provides more reliable support, reduces structural deformation and potential safety hazards, and is made of metal materials, which are durable and can be reused multiple times, further reducing the material cost and resource waste. It has strong adaptability and can be used for roof construction with different slopes and complex structures, with significant economic benefits and practical value.

[0020] In summary, through the optimized design of the structure, the present utility model not only solves the defects of the traditional wooden wedge structure, but also improves the construction efficiency and stability, and reduces the material cost, with significant economic benefits and practical value.
