Abstract
Description
Technical Field
[0001] An environmentally friendly construction device for steel frame floor decking that requires no support, belonging to the field of floor decking construction technology. Background Technology
[0002] In existing steel structure construction projects, the application of prefabricated steel truss floor decks is gradually increasing. These floor decks typically require reinforcement using support systems such as socket-type disc-lock scaffolding. Currently, the construction of prefabricated steel structure residential steel truss floor decks usually employs simply supported, yet braced, structures. However, even with a simply supported, braced construction structure, the steel truss floor deck requires a support system such as socket-type disc-lock scaffolding to reinforce and stabilize the lower part of the floor deck during pouring. This support system requires a large amount of scaffolding, significantly increasing the amount of manual installation and dismantling work and the construction load. However, before the concrete is poured, the compressive bearing capacity of the steel columns in prefabricated steel structure residential buildings is relatively low. Using a reinforcement and support structure can cause significant deformation of the steel columns due to the construction load, affecting the construction quality of the steel structure.
[0003] The Chinese invention patent with application number 202211297216.X and application date of October 21, 2022, entitled "A Construction Structure and Method for Installing Steel Truss Floor Slabs in Prefabricated Steel Structure Residential Buildings", describes a technical solution. In this technical solution, a detachable tension beam is set on the building structure. The tension beam generates tension on the support beam through the tension rod group, keeping the steel truss floor slab stable in position during the pouring construction. This technical solution can effectively reduce the amount of construction work of the support system and reduce construction costs. However, this technical solution still has the following defects in specific implementation: (1) The tension beam in this solution is fixed to the surface of the prefabricated steel structure residential building structure by the support. Although the triangular support has a stabilizing effect, the height of the support is relatively fixed. In actual construction, there may be multiple pouring surfaces with different heights on a whole working surface. Therefore, when this situation is encountered, it is necessary to set supports with different heights to support the tension beam. Therefore, its applicability is poor and it increases the construction cost to a certain extent. (2) After the pouring is completed, the tie bolts are also poured into the concrete. In the later stage, the tie bolts need to be cut, which is a complicated process. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a support column with adjustable height on the surface of the steel beam. This column supports the beam and allows for adjustment of the beam's height, making it suitable for steel frame floor decking without support for applications requiring different concrete heights on the same work surface.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: the steel frame floor deck support-free environmentally friendly construction device includes multiple steel beams arranged side by side, a casting surface is provided on the surface of the steel beams, several trusses are fixed on the surface of the casting surface, several sets of supporting beams are provided above the casting surface, and several sets of hanging beams are provided on the bottom surface of the casting surface.

The characteristic is that the supporting members include multiple sets, and the multiple sets of supporting members are arranged perpendicularly to the surface of the steel beams along the length direction of the steel beams. Each set of supporting members includes multiple height-adjustable supporting columns.
[0006] Preferably, the support column includes two bolts with opposite thread directions, and an adjusting sleeve is fitted at the joint of the two bolts, with the adjusting sleeve being threadedly connected to both bolts.
[0007] Preferably, the arrangement direction of the supporting beams is perpendicular to the arrangement direction of the steel beams, and each supporting beam is set on the surface of multiple supporting columns that are located on the same straight line on the surface of all steel beams.

[0013] Preferably, multiple base frames are installed at the bottom of each truss, and the base frames are simultaneously fixed to the cast surface.
[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Each tie bolt is fitted with a casting sleeve, the height of which is higher than the concrete pouring height. Therefore, after pouring and curing, only the casting sleeve is left embedded in the concrete, and the tie bolts can be removed along with the supporting beam and hanging beam, achieving the reuse of the tie bolts. More importantly, it avoids the subsequent cutting process. Attached Figure Description

[0020] Figures 1-2 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-2 The present invention will be further described below.
[0021] like Figures 1-2 As shown, a steel frame floor deck support-free environmentally friendly construction device (hereinafter referred to as this construction structure) includes multiple steel beams 11 arranged side by side. The steel beams 11 are made of I-beams, which are common in this field. Several base plates 9 are laid on the surface of all the steel beams 11. The base plates 9 are made of cement fiberboard, which is common in this field. The two ends of each base plate 9 are respectively attached to the edges of two adjacent steel beams 11. Thus, a casting surface is formed by the joint of all the steel beams 11.
[0022] Several trusses 4 are arranged side by side on the cast-in-place surface formed by the butt joint of the base plate 9. The trusses 4 are implemented using structures known in the art, which will not be described in detail here. The arrangement direction of the trusses 4 is perpendicular to the arrangement direction of the steel beams 11. At the bottom of each truss 4, multiple base frames 8 are also provided. The base frames 8 at the bottom of each truss 4 are arranged along the length of the truss 4, and the two ends of each base frame 8 are respectively connected to the steel bars at the bottom of the truss 4. Each truss 4 is placed on the surface of the base plate 9 through its base frame 8, and the base frame 8 is fixed to the base plate 9, thus realizing the fixation of the truss 4 and the base plate 9.
[0023] Multiple sets of adjustable supports are provided in the middle of the upper surface of each steel beam 11. The adjustable supports are arranged along the length of the steel beam 11 and are located between two base plates 9 erected on the upper surface of the steel beam 11. Each set of adjustable supports includes two support columns 5 arranged side by side. Several supporting beams 3 are erected above all the steel beams 11. Each supporting beam 3 includes two supporting beams arranged in parallel. The arrangement direction of the supporting beams 3 is perpendicular to the arrangement direction of the steel beams 11.
[0024] Several adjustable supports located on the same straight line on the surfaces of all steel beams 11 jointly support a supporting beam 3. Two supports in each supporting beam 3 are placed on the surface of the support column 5 in the corresponding adjustable support rod. That is, multiple support columns 5 on the surfaces of different steel beams 11 that are located on the same straight line jointly support a supporting beam 3.
[0025] The support column 5 includes two bolts with opposite thread directions. An adjusting sleeve 7 is provided at the joint of the two bolts. The two bolts are threadedly connected to the adjusting sleeve 7. One bolt is fixed to the surface of the steel beam 11, while the other bolt supports the supporting beam 3. Because the adjusting sleeve 7 is threaded to the bolts with opposite thread directions, rotating the adjusting sleeve 7 in the middle of multiple support columns 5 with different steel beam 11 surfaces located on the same straight line allows for adjustment of the height of the corresponding supporting beam 3. This is suitable for construction requirements where different heights of concrete need to be installed on the same working surface.
[0026] At least one set of hanging support beams 12 are also provided at the bottom of two adjacent steel beams 11. The arrangement direction of the hanging support beams 12 is parallel to the arrangement direction of the steel beams 11, and each hanging support beam 12 includes two beams arranged side by side. The hanging support beams 12 and the supporting beams 3 are respectively arranged perpendicularly above and below the base plate 9, and the hanging support beams 12 and the supporting beams 3 are also fixed by several tie rods. Since the vertical projections of the hanging support beams 12 and the supporting beams 3 are perpendicular to each other, the tie rods are located at any point where the hanging support beams 12 and the supporting beams 3 intersect perpendicularly.
[0027] The tie rod assembly includes tie bolts 1, with the upper part of each tie bolt 1 passing through the two supporting beams 3 of each group, and the bottom of the tie bolt 1 passing through the two hanging beams 12 of each group. Each tie bolt 1 is also provided with butterfly buckles 2 at the upper and lower parts. The upper butterfly buckles 2 fix the two supporting beams 3, and the lower butterfly buckles 2 fix the two hanging beams 12 and are close to the bottom surface of the base plate 9. Finally, they are locked by the upper and lower nuts. The adjustable support members on the upper surface of the steel beam 11 are used to fix the intersecting supporting beams 3 and hanging beams 12 into one unit. When fixing the supporting beams 3 and hanging beams 12, the tie bolts 1 pass through the truss 4 and the base plate 9 at the same time.
[0028] The specific working process and working principle are as follows:
[0029] The above-described construction structure is assembled using construction steps known in the art. Concrete is then poured onto the surface of the base plate 9. After pouring and curing, the supporting beam 3 and the hanging beam 12 are removed. Several casting bolts 10 are vertically installed along the length of the steel beam 11, located on both sides of the support column 5. After pouring, the casting bolts 10 are simultaneously poured into the concrete, increasing the pouring strength between the steel beam 11 and the concrete. Simultaneously, a casting sleeve 6 is fitted over each tie bolt 1. The height of the casting sleeve 6 is higher than the pouring height of the concrete. Therefore, after pouring and curing, only the casting sleeve 6 is poured into the concrete, allowing the tie bolt 1 to be removed along with the supporting beam 3 and the hanging beam 12. This achieves the reuse of the tie bolt 1 and, more importantly, avoids the subsequent cutting process. The through holes of the casting sleeve 6 are then sealed after the tie bolt 1 is removed.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
