Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a formwork support and inclined floor slab formwork system and a construction method. Background Art

[0002] In the construction of floor slab casting, a formwork is usually installed on the ground below, and then a top support is installed on the formwork to support the formwork of the floor slab to be constructed above. In building construction, when there is a non-horizontal floor slab, that is, an inclined floor slab, the traditional top support cannot meet the inclined support of the inclined floor slab for the formwork of the inclined floor slab, and it is difficult to provide effective vertical support for the floor slab formwork to be cast above. The traditional top support includes a support rod and a vertically arranged support plate. When the top support of this structure supports the floor slab formwork to be cast above, there is a point contact between the support plate and the formwork, and there is a gap, and the keel of the formwork system cannot be wrapped, resulting in an unreliable support connection between the top support and the formwork, which leads to safety problems such as the floor slab formwork being prone to overturning or collapse. For syncline floors, when the support plate is set on the support rod according to the inclination angle of the inclined floor slab to form a special top support, it is necessary to match and manufacture different support plates with inclined surfaces according to the different inclination angles of the inclined floor slabs, which has poor versatility and cannot be reused, resulting in serious waste. Summary of the invention

[0003] The purpose of the present invention is to provide a formwork support, an inclined floor formwork system and a construction method to solve the problems that the conventional top supports of the inclined floor are unreliable in connection with the formwork and cannot effectively support the formwork, the safety is poor, and the special top supports have poor versatility and a long on-site production cycle that affects the construction progress.

[0004] In order to solve the above technical problems, the present invention provides a formwork support, including a base, a top rod and a support plate, the base includes a horizontally arranged seat plate and a middle rod and a bottom rod vertically connected up and down, the middle rod is hinged to the lower end of the top rod through a movable part, and the support plate and the seat plate located on the same side are hinged with a basket bolt.

[0005] Furthermore, in the formwork support provided by the present invention, the cross-section of the support plate is U-shaped.

[0007] Furthermore, in the formwork support provided by the present invention, the movable component is a hinged body with a locking device.

[0008] Furthermore, in the formwork support provided by the present invention, the top rod, the middle rod and the bottom rod are all solid columns.

[0009] In order to solve the above-mentioned technical problems, the present invention also provides a formwork system for an inclined floor slab, comprising a support frame arranged below the inclined floor slab to be cast, and a formwork top support as described above arranged between a plurality of vertical poles evenly distributed at the top of the support frame and the formwork system of the inclined floor slab to be cast.

[0010] Furthermore, in the inclined floor slab formwork system provided by the present invention, the supporting frame is formed by splicing and assembling a plurality of transverse steel pipes, a plurality of longitudinal steel pipes and a plurality of vertical steel pipes, and the vertical steel pipes are vertical poles.

[0011] Furthermore, in the inclined floor formwork system provided by the present invention, the formwork top support is connected to the vertical pole at the corresponding position through the bottom rod, and the formwork top support is supported on the keel of the formwork system of the inclined floor to be cast through the support plate.

[0012] In order to solve the above technical problems, the present invention also provides a construction method according to the above-mentioned inclined floor slab formwork system, by adjusting the length of the basket bolt, the top rod is adjusted at an angle relative to the base through a movable part, so that the inclination angle of the top rod is consistent with the inclination angle of the inclined floor slab, so that the support plate of the formwork top support after adjusting the inclination angle can perform parallel fitting support on the formwork system of the inclined floor slab.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

The seat maintains an inclined angle, and bears the load during the pouring of the inclined floor slab through the support plate, jack, movable parts, base and basket bolts and transfers the load to the supporting frame, thereby improving the vertical bearing capacity during the pouring of the inclined floor slab, ensuring the reliability, stability and safety of the formwork system supported by the formwork jacking during the pouring construction of the inclined floor slab, avoiding the problem of unstable and unreliable support for the inclined floor slab due to gaps caused by point contact between the traditional support plate and the formwork system, and avoiding the safety problem of overturning or collapse of the formwork system of the inclined floor slab during the concrete pouring process.

[0030] Please refer to Figure 2 An embodiment of the present invention further provides a formwork support 120 of the above structure.

[0031] Please refer to Figure 2 The embodiment of the present invention also provides a construction method for the above-mentioned inclined floor formwork system 1, by adjusting the length of the basket bolt 127 to adjust the angle of the top rod 125 relative to the base through the movable part 124, so that the inclination angle of the top rod 125 is consistent with the inclination angle of the inclined floor 200, so that the support plate 126 of the formwork support 120 after adjusting the inclination angle is used to parallelly fit and support the formwork system 300 of the inclined floor 200.
