And the problem that a reinforcing rod drives a plurality of L-shaped stair formworks to displace and deform is solved.

Description

Technical Field

[0001] The utility model relates to a construction structure for supporting a staircase formwork, belonging to the technical field of building construction. Background Technique

[0002] When constructing a building, the floors need to be connected by stairs. Before pouring the upper floor slab, the stairs need to be poured. Before pouring the cast-in-place stairs, a rest platform formwork and a step formwork need to be erected. To ensure the spacing between the step formworks, a strengthening rod is required to strengthen the connection of the step formworks.

[0003] For the existing technology of strengthening the connection of the step formwork, see Chinese Patent Publication No. CN208858151U. Although the reinforcing rod can connect the L-shaped staircase formwork to ensure the spacing between the L-shaped staircase formworks, when the reinforcing rod is loaded during construction, since the reinforcing rod only connects the L-shaped staircase formwork and the load is only transmitted through the L-shaped staircase formwork, the reinforcing rod will cause displacement and deformation of multiple L-shaped staircase formworks. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a construction structure for supporting a staircase formwork.

[0005] The utility model is achieved through the following technical solutions.

[0006] A construction structure for supporting a staircase formwork provided by the utility model includes:

[0007] A strengthening rod for strengthening the spacing of the vertical step formworks;

[0008] Through bolts B, A, and C are correspondingly installed at the upper, middle, and lower parts of the strengthening rod.

[0009] It also includes a step back formwork, a step horizontal formwork, and a vertical step formwork that form a space for the solidification of the staircase steps; there is a step back rib for supporting at the bottom of the step back formwork, an upper rest platform formwork above the step back formwork, and a lower rest platform formwork below the step back formwork.

[0010] An upper rest back rib is installed at the bottom of the upper rest platform formwork; a lower rest back rib is installed at the bottom of the lower rest platform formwork.

[0011] The step back formwork is spaced with a horizontally arranged step horizontal formwork, and the step horizontal formwork is connected with a vertically arranged vertical step formwork. The step horizontal formwork and the vertical step formwork are all arranged in a mutually intersecting and connected manner.

[0012] The bottom of the reinforcing rod is fixedly connected with a vertical plate, and the vertical plate is fixed to the vertical step formwork. The middle part of the reinforcing rod is fixedly connected through a through bolt A with the step back rib in a through manner. The upper and lower ends of the reinforcing rod are fixedly connected through a through bolt B and a through bolt C with the upper rest back rib and the lower rest back rib in a through manner respectively.

[0013] There is a correction seat on the reinforcing rod to make the through bolt B and the through bolt C in a vertical state for installation.

[0014] It further includes a support frame whose bottom is erected from the support of the formed staircase. The top of the support frame supports the step back rib, the upper rest back rib, and the lower rest back rib.

[0015] The support frame is composed of vertical rods, cross bars connecting the vertical rods horizontally, and longitudinal rods connecting the vertical rods longitudinally. A jack is installed at the top of the vertical rod to correspondingly hold and support the step back rib, the upper rest back rib, and the lower rest back rib.

[0016] The beneficial effect of the present utility model is that when the reinforcing rod is subjected to a load, the reinforcing rod can transfer and disperse the load to the step back rib, the upper rest back rib, and the lower rest back rib through the through bolt A, the through bolt B, and the through bolt C, ensuring the spaced reinforcement of the reinforcing rod to the vertical step formwork, and solving the problem that the reinforcement rod only transfers the load through the L-shaped staircase formwork, which will cause the reinforcement rod to drive multiple L-shaped staircase formworks to displace and deform.

Detailed Embodiment

[0019] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0020] As Figure 1 shown.

[0021] A staircase formwork support construction structure of the present application includes:

[0022] A step back rib 11 for supporting the step back template 1, an upper rest platform template 2 above the step back template 1, and a lower rest platform template 3 below the step back template 1.

[0023] The upper rest platform formwork 2 is installed with upper rest back ribs 21 at the bottom; the lower rest platform formwork 3 is installed with lower rest back ribs 31 at the bottom.

[0024] It further includes a support frame 5. The bottom of the support frame 5 is erected from the already formed staircase support, and the top of the support frame 5 supports the step back ribs 11, the upper rest back ribs 21, and the lower rest back ribs 31.

[0025] The step back formwork 1 is installed with step horizontal formworks 12 in a horizontal state at intervals. The step horizontal formworks 12 are connected and installed with vertical step formworks 13 in a vertical state. The step horizontal formworks 12 and the vertical step formworks 13 are all erected by crossing and connecting with each other in multiple numbers. The connection between the step horizontal formwork 12 and the vertical step formwork 13 is fixed with nails. A space is formed among the step back formwork 1, the step horizontal formwork 12, and the vertical step formwork 13 for later pouring of concrete to solidify and form staircase steps.

[0026] It further includes a reinforcing rod 4 for strengthening the connection and bearing force of the step horizontal formwork 12 and the vertical step formwork 13. The bottom of the reinforcing rod 4 is fixedly connected with a vertical plate 41 by nails. The vertical plate 41 is fixed with the vertical step formwork 13 by nails. The middle part of the reinforcing rod 4 is fixedly connected with the step back rib 11 by a through bolt A42 in a through manner. The upper and lower ends of the reinforcing rod 4 are fixedly connected with the upper rest back rib 21 and the lower rest back rib 31 by through bolts B43 and C44 in a through manner respectively. The through bolts B43 and C44 are installed in a vertically perpendicular state through a correction seat 45 on the reinforcing rod 4.

[0027] When the reinforcing rod 4 is subjected to a load, the reinforcing rod 4 can transfer and disperse the load to the step back rib 11, the upper rest back rib 21, and the lower rest back rib 31 through the through bolt A42, the through bolt B43, and the through bolt C44, ensuring the spaced reinforcement of the vertical step formwork 13 by the reinforcing rod 4, and solving the problem that the reinforcement rod only transfers the load through the L-shaped staircase formwork, which will cause the displacement and deformation of multiple L-shaped staircase formworks with the reinforcement rod. The through bolt A42, the through bolt B43, and the through bolt C44 can limit the position of the reinforcing rod 4.

[0028] The support frame 5 is composed of vertical rods, horizontal rods connecting the vertical rods horizontally, and longitudinal rods connecting the vertical rods longitudinally. The top of the vertical rod is installed with a jack to correspondingly hold and support the step back rib 11, the upper rest back rib 21, and the lower rest back rib 31.
