Description

Technical Field

[0001] The present application relates to the field of turnover material accessories for formwork engineering in construction, and more specifically to a support pole system with early-detachable strip support belt secondary keels. Background Art

[0002] In the prior art, before pouring the floor slab, a floor formwork structure for bearing and supporting the concrete must first be constructed. To ensure the stability of the floor formwork, a support frame for supporting the floor formwork must be constructed below the floor formwork structure. The support frame is composed of several vertical support posts, horizontal tie rods installed between the support posts, and slab supports inserted at the tops of the support posts. In most traditional wooden floor formwork structures, a U-shaped support is first inserted at the top of the support posts and rests below a main purlin made of Φ48 round tubes or I-beam steel plates. The main purlin is then supported by a U-shaped support tray, and several secondary wooden or ordinary iron purlins perpendicular to the main purlin are then supported by these main purlins to provide multiple supports below the floor formwork. Furthermore, the distance between the U-shaped support surface and the nearest horizontal tie rod at the bottom cannot exceed 600mm, meaning the free end does not exceed 600mm. Therefore, this support method does not allow for the early removal of the main and secondary floor purlins and the floor formwork.

[0003] For floors within 3.6 meters in height, the U-shaped supports without main keel joints can only be lowered and the supporting poles removed after the beam-slab concrete structure reaches the demolition strength. Then, the U-shaped slab supports with main keel joints can be lowered by about 50mm. Then, steel pipes or wooden squares can be used to tilt the lower ends of the supporting poles with main keel joints along the main keel and toward the outside of the building until the main keel collapses and falls toward the middle of the building. After all supporting poles and main keels are removed in this way, the secondary wooden keels that may fall can be removed, cleaned, classified and piled up. Finally, the secondary wooden keels, beam side formwork, and floor formwork can be removed in turn. This is commonly known as barbaric formwork removal, which does not guarantee the safety of workers and causes significant damage to the primary and secondary keels and formwork.

[0004] When the floor height exceeds 3.6 meters, first lower the U-shaped board top support without the main keel end. When these top supporting poles can be removed, directly remove them and throw them to the ground. Then lower the U-shaped board top support with the main keel end. Remove the wooden secondary keels that have fallen on the lowered main keel and those that may fall and throw them to the ground. Then, two construction workers will jointly remove the main keels in turn and place them on the stepped horizontal tie rods. Then, remove the top poles and board top support that can be removed in turn and throw them to the ground. Finally, remove the wooden secondary keels, beam side formwork, floor formwork, etc.

[0005] Some construction sites now use counterfeit or upgraded foreign traditional wooden formwork early-dismantling top supports, but the early-dismantling heads are extended to the floor concrete or early-dismantling strip floor formwork through flat plate top supports of various shapes, and the main keels are placed on main keel pallets of various shapes. The maximum distance from the early-dismantling head surface of the slab top support to the nearest horizontal tie rod at the lower end is about 750mm, and the maximum distance from the main keel pallet surface to the nearest horizontal tie rod at the lower end is within 600mm.

[0006] In the actual traditional wooden formwork early dismantling construction process, all primary and secondary purlins are directly removed, leaving the supporting structure of the floor formwork only with the flat plate early dismantling head. Its support for 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. This can easily lead to a large number of hidden cracks within the floor slab due to excessive concentration of support force, thereby reducing the overall service life of the floor slab. After years of research, our company has found that when performing early dismantling of secondary purlins, while removing some of them, retaining the secondary purlin at the top of the slab support that is always connected to the floor formwork, the existing point support can be adjusted to linear support, which can greatly reduce the occurrence of hidden cracks, better ensure the quality of the floor slab, and greatly extend the service life of the floor slab.

Moreover, this product can be used for non-early removal and can realize the early removal of all main purlins and most secondary purlins.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Example

[0036] like Figure 1 、 2 As shown, a supporting pole system with early-detachable strip support belt secondary purlins includes a plurality of supporting poles 1000 and a plurality of transverse tie rods 2000 arranged between the supporting poles 1000, a plate top supporting structure 3000 arranged on the supporting poles 1000, a plurality of mutually parallel main purlins 4000 arranged on the plate top supporting structure 3000, a plurality of mutually parallel early-detachable strip support belt secondary purlins 5000 arranged on the plate top supporting structure 3000, and a plurality of mutually parallel square secondary purlins 6000 arranged on the main purlin 4000 and located between two adjacent early-detachable strip support belt secondary purlins 5000.

[0037] The supporting pole is a prior art, which is composed of a base 1100, a lower pole 1200 and an upper pole 1300. Its configuration and use are prior art in this field and will not be described in detail here.

[0038] A plurality of the main keels 4000 are arranged on the same horizontal plane, and a plurality of the early-removal strip support belt secondary keels 5000 are arranged on the same horizontal plane; the main keels 4000 are perpendicular to the early-removal strip support belt secondary keels 5000.

[0039] like Figure 3-5As shown, the plate top support structure 3000 includes a threaded connecting rod 3100 inserted into the supporting vertical pole from above, two support nuts 3200 sleeved on the threaded connecting rod 3100, a main keel tray 3300 sleeved on the threaded connecting rod 3100 and located on the upper side of the support nuts 3200, and a secondary keel support 3400 arranged at the top of the threaded connecting rod 3100; the outer side wall of the threaded connecting rod 3100 is provided with an external thread.

[0040] The support nut 3200 is composed of an internally threaded sleeve 3201 with an internal thread, a rotating handle 3202 arranged at the end of the outer wall of the internally threaded sleeve 3201, and an anti-tilt ring 3203 arranged at the end of the internally threaded sleeve 3201 and adjacent to the rotating handle; the internal thread arranged in the internally threaded sleeve 3201 matches the external thread arranged on the threaded connecting rod 3100.

[0041] The functions of the two support nuts are: (1) to adjust the length of the threaded connecting rod extending out of the supporting vertical pole so that the top of the threaded connecting rod can support the floor formwork after the early-removal strip support belt secondary keel is set; (2) to support the main keel support and adjust the height of the main keel support according to the setting requirements.

[0042] The total length of the upper upright and the slab support structure is generally 2240mm to 2540mm or 1740mm to 1940mm. If the total length exceeds the above range, the slab support structure will extend too long or too far, resulting in non-compliant use, increasing the overall difficulty and effectiveness of use. In buildings with a floor height of 2.9 meters to 3.5 meters, the optimal length is 2390mm or 1890mm. This size can better meet the construction requirements of early demolition or non-early demolition. However, during early demolition construction, the bottom base must use a concrete base. When the formwork is 150mm, the slab support structure extends for about 43mm, so it can barely complete the early demolition of the formwork.

[0043] The types of threaded connecting rods in the slab top support structure are generally divided into A+, B+ and D+ types. The length of the A+ type threaded connecting rod is 510mm, the length of the B+ type threaded connecting rod is 1100mm, and the length of the D+ type threaded connecting rod is 520mm; the A+ type threaded connecting rod is mainly used on beams with a height of 450mm to 750mm, the B+ type threaded connecting rod is mainly used on beams with a height of 750mm to 1350mm, and the D+ type threaded connecting rod is mainly used when the beam height is 1250mm.

[0044] The main keel tray 3300 consists of a main keel support plate 3301, a main keel seat 3302 arranged on the lower side of the main keel support plate 3301, two main keel support plate reinforcement plates 3305 symmetrically fixed on both sides of the main keel seat 3302 and with the upper ends fixed to the lower side of the main keel support plate 3301, four main keel side limiting plates 3303 vertically arranged on the upper side of the main keel support plate 3301 and parallel to each other, and three main keel fixing holes 3304 arranged in a row on the main keel side limiting plates 3303; the main keel seat 3302 is cylindrical and is arranged at the center of the main keel support plate 3301; the threaded connecting rod 3100 is coaxial with the main keel seat 3302, and the threaded connecting rod 3100 passes through the main keel seat 3302 and the main keel support plate 3301 at the same time.

[0045] The four main keel side limiting plates 3303 are arranged in groups of two, and the two groups of main keel side limiting plates 3303 are symmetrically arranged on both sides of the threaded connecting rod 3100.

[0046] When in use, the two main keels arranged in groups are respectively set between the two groups of main keel side limit plates, and the main keels and the main keel supports are fixed by pins that penetrate the main keel fixing holes and the fixing holes on the main keels, so that the main keels can be raised and lowered as the main keel supports are raised and lowered.

[0047] The main keel is an existing technology, and the technical solution of setting fixing holes on the main keel for fixing the main keel is also an existing technology. Those skilled in the art can complete the setting and use of the main keel without creative labor, so it will not be elaborated here.

[0048] The secondary keel support 3400 consists of a secondary keel support plate 3401, two secondary keel support plate reinforcement plates 3402 arranged on the lower side of the secondary keel support plate 3401, two secondary keel side limiting plates 3403 vertically arranged on the upper side of the secondary keel support plate 3401 and parallel to each other, and three secondary keel fixing holes 3404 arranged on the secondary keel side limiting plates 3403.

[0049] The top of the threaded connecting rod 3100 is set at the center position of the lower side of the secondary keel support plate 3401, and the secondary keel support plate reinforcement plate 3402 is symmetrically set on the left and right sides of the threaded connecting rod 3100; the secondary keel support plate reinforcement plate 3402 is fixed to the threaded connecting rod 3100 and the secondary keel support plate 3401 at the same time.

[0050] When in use, the square frame secondary keel is set on the main keel, and the early-removal strip support belt secondary keel is set between the two secondary keel side limit plates. The early-removal strip support belt secondary keel and the secondary keel support are fixed by pins that pass through the secondary keel fixing holes and the fixing holes of the early-removal strip support belt secondary keel. As a result, the main keel can only drive the square frame secondary keel to rise and fall when it is raised or lowered, and will not affect the position of the early-removal strip support belt secondary keel. Therefore, when the main keel and the square frame secondary keel are dismantled and transported, the early-removal strip support belt secondary keel can still maintain support for the floor formwork.

[0051] The above-mentioned square frame secondary purlin has the same structure as the early-removal strip support belt secondary purlin and its structure is both existing technology. Its main body is a square tube, and fixing holes are provided on the square tube for fixing, which can be used for fixing the square tubes and fixing the square tubes to other supporting structures. Those skilled in the art can complete the setting and use of the square frame secondary purlin and the early-removal strip support belt secondary purlin without creative labor, so they will not be elaborated here.

[0052] Since the early-removal strip support belt secondary keel is set, the two adjacent support uprights can be effectively connected through the early-removal strip support belt secondary keel, so it can effectively replace the two transverse tie rods that originally needed to be set at the top, thereby reducing the overall setting amount of transverse tie rods, avoiding the top transverse tie rods from occupying the operating space, and ensuring the overall stability while reducing the use of transverse tie rods.

[0053] The secondary keel side limiting plate 3403 is perpendicular to the main keel side limiting plate 3303 .

[0054] The length of the secondary keel support plate 3401 is the same as the spacing between the two groups of the main keel side limit plates 3303; the two ends of the secondary keel side limit plates 3403 extend out of the secondary keel support plate by 40 mm respectively, and the lower side surface of the secondary keel side limit plate 3403 and the upper side surface of the secondary keel support plate 3401 are located on the same horizontal plane.

[0055] When the main keel is installed between the groups of main keel limit plates, the lower side of the secondary keel side limit plates can cooperate with the main keel support plate to further clamp the main keel. At the same time, because the lower sides of all secondary keel side limit plates are set at the same horizontal plane, it can effectively ensure that the upper sides of all main keels are located at the same horizontal plane, which greatly reduces the difficulty of subsequent construction and ensures construction quality.

[0056] Because the length of a single square frame secondary purlin or early-detachment strip support strip secondary purlin is limited, multiple square frame secondary purlins or early-detachment strip support strip secondary purlins may need to be spliced ​​together during use. Connectors are required between the two square frame secondary purlins or early-detachment strip support strip secondary purlins to be spliced. Therefore, the square tubes are provided with three fixing holes: the central fixing hole is used to secure to the connecting piece on the square frame secondary purlin or early-detachment strip support strip secondary purlin, and the front and rear fixing holes are respectively secured to the square frame secondary purlins or early-detachment strip support strip secondary purlins located at both ends of the connecting piece.

[0057] Example 2

[0058] like Figure 6 As shown, the only difference between this embodiment and embodiment 1 is that the number of the main keel fixing hole 3304 provided on the main keel side limiting plate 3303 is one.

[0059] Because when the main keel is set between the groups of main keel limiting plates, the lower side of the secondary keel side limiting plate can cooperate with the main keel support plate to further clamp the main keel, so the main keel can be well fixed through only one main keel fixing hole. At the same time, the main keel can also effectively play the role of a transverse tie rod, reducing the number of transverse tie rods required in actual setting.

[0060] Example 3

[0061] This embodiment differs from Examples 1 and 2 only in that two sets of nail holes are symmetrically positioned on the two secondary keel side retaining plates of the secondary keel support. The purpose of providing these nail holes is to ensure that the product can still be effectively secured to wooden secondary keels when used on-site. To ensure compatibility with steel-clad wood formwork, the spacing between the central axis of the nail holes and the upper side of the secondary keel support plate is set at 30 mm.

[0062] In addition, nail holes are also provided on the side limit plates of the main keel. The purpose of setting them is that when the main keel is made of wood, the product can still be effectively fixed to the main keel made of wood. The distance between the center axis of the nail hole and the upper side of the main keel support plate is set to 30mm.

[0063] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
