Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to an adjustable support structure that facilitates the installation of composite slabs. Background Technology

[0002] In prefabricated building construction, the choice of support system for the composite slab installation stage directly affects the project's achievement of the core objectives of "efficiency, economy, and precision." Currently, some projects still use a traditional top-bracing combined with full-span scaffolding support scheme. Although this can meet basic load-bearing requirements, it is significantly out of step with the advantages of prefabricated buildings, becoming a key bottleneck restricting construction efficiency and cost control.

[0003] From the perspective of on-site construction efficiency, the erection and dismantling of traditional support systems involves a large workload and cumbersome processes. Full-span scaffolding requires erecting each upright and horizontal bar individually, and leveling each layer in conjunction with top supports. This not only consumes a large amount of reusable materials such as fasteners and steel pipes, but also requires a significant amount of labor for repetitive erection work, resulting in a substantial extension of the support system construction cycle. This contradicts the efficient concept of prefabricated buildings—"components prefabricated in factories and rapidly assembled on-site"—making it difficult to achieve rapid construction and assembly line operations within a short timeframe. Furthermore, the procurement, transportation, storage, and losses of reusable materials, coupled with the large amount of labor input, directly increase construction costs. Excessive construction time for support systems extends the overall project duration, thereby increasing indirect costs such as management fees and equipment rental fees. Traditional top supports rely on manual point-by-point adjustments, which are easily affected by the skill level, sense of responsibility, and site environment of the construction workers, leading to elevation errors in the installation of composite slabs that can exceed the allowable range specified in the standards. Improper elevation control can not only affect subsequent floor slab construction, but also lead to uneven gaps in component splicing, increasing later rectification costs, and even posing a hidden danger to the overall stability of the building structure, thus violating the original intention of "precision construction" in prefabricated buildings.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Summary of the Invention

[0008] Preferably, the straight threaded sleeve is horizontally arranged, and the axis of the straight threaded sleeve is perpendicular to the precast wall panel.

Detailed Implementation

[0019] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example 1

[0020] like Figure 1 As shown, Figure 1 This is a structural view of the adjustable support structure that facilitates the installation of the composite slab.

[0021] The adjustable support structure for easy installation of composite slabs according to this utility model includes a precast floor slab 1, a precast wall panel 2, and a support base 3. A straight threaded sleeve 4 is pre-embedded on the precast wall panel 2, and a connecting bolt is connected to the support base 3 through the straight threaded sleeve 4, thereby realizing the detachable fixation of the support base 3 on the precast wall panel 2. The bottom of the precast floor slab 1 is in contact with the support base 3, so that the precast floor slab 1 is horizontally supported and positioned by the support base 3. At least two precast wall panels 2 are correspondingly provided on the precast floor slab 1, and the two precast wall panels 2 are symmetrically arranged on both sides of the precast floor slab 1, so that the support base 3 on the two precast wall panels 2 can effectively level and support the precast floor slab 1.

[0022] Specifically, the precast floor slab 1 is a horizontally arranged planar plate, and the top surface of the precast floor slab 1 is provided with a cast-in-place groove 11, which extends in a straight line along the edge of the precast floor slab 1; the precast wall panel 2 is a vertically arranged planar plate, and one side of the precast wall panel 2 is provided with an insulation board 21 and an outer leaf plate 22 in sequence, and the precast floor slab 1 is provided at the upper end of the other side of the precast wall panel 2. The bottom edge of the precast floor slab 1 rests on the support base 3, and the precast floor slab 1 and the precast wall panel 2 are in close contact. The top surface of the insulation board 21 is higher than the top surface of the precast wall panel 2. The cast-in-place groove 11 of the precast floor slab 1 forms a strip-shaped L-shaped cross-section cast-in-place space 23 on the top surface of the precast wall panel 2. Concrete is poured into the cast-in-place space 23 to form a composite slab.

[0023] This utility model, by setting up a support structure that is directly positioned and connected to the wall, completely eliminates the tedious work of erecting and dismantling a large amount of scaffolding, avoids the problem of poor elevation accuracy caused by manual point-by-point leveling, and reduces the consumption of turnover materials and construction delays. Ultimately, it significantly improves construction efficiency and greatly shortens the construction cycle of the support system; improves installation quality and ensures that the elevation error of the composite slab meets the specifications; and improves cost-effectiveness by reducing labor and material inputs to reduce overall construction costs, fully meeting the construction goals of efficient, precise and economical prefabricated buildings. Example 2

[0024] like Figure 2 and Figure 3 As shown, Figure 2 This is a front view of the structure of the support base; Figure 3 This is a structural side view of the support base.

[0025] The support base 3 includes a connecting plate 31, a support plate 32, and a reinforcing plate 33. The ends of the connecting plate 31 and the support plate 32 are vertically fixedly connected to form an L-shaped structure. The reinforcing plate 33 is fixedly connected to both the connecting plate 31 and the support plate 32. The connecting plate 31 is provided with a mounting hole 34. The connecting bolt passes through the mounting hole 34 and is threadedly connected to the straight threaded sleeve 4, thereby realizing the installation of the support base 3 on the precast wall panel 2. The support plate 32 is horizontally arranged at the bottom of the precast floor slab 1 and contacts the bottom surface of the precast floor slab 1, thereby realizing the horizontal support of the precast floor slab 1.

[0026] Preferably, the straight threaded sleeve 4 is horizontally arranged, and the axis of the straight threaded sleeve 4 is perpendicular to the precast wall panel 2, so as to facilitate the stable installation of the support base 3 on the precast wall panel 2.

[0027] Multiple straight threaded sleeves 4 are equidistantly arranged in the height direction of the same precast wall panel 2, thereby improving the applicability of the precast wall panel 2 and making it easy for the precast wall panel 2 to be used with precast floor slabs 1 at different heights.

[0028] Preferably, the reinforcing plate 33 is configured as a right-angled triangular plate, and the two right-angled sides of the reinforcing plate 33 are fixedly connected to the connecting plate 31 and the supporting plate 32 respectively, so as to ensure the supporting strength of the supporting base 3.

[0029] The connecting plate 31 is provided with four mounting holes 34, which are arranged symmetrically in pairs. The two symmetrical mounting holes 34 are respectively located on both sides of the reinforcing plate 33 to improve the connection strength between the support base 3 and the precast wall panel 2, and also to facilitate the installation of the connecting bolts.

[0030] Correspondingly, the four straight threaded sleeves 4 on the precast wall panel 2 form a fixing group. The straight threaded sleeves 4 on the fixing group are set one-to-one with the mounting holes 34 on the connecting plate 31 to ensure the connection between the connecting plate 31 and the precast wall panel 2.

[0031] The precast wall panel 2 is provided with multiple fixing groups of different heights, and the fixing groups are staggered in the horizontal direction to avoid the straight threaded sleeves 4 in different fixing groups being too close together, which would affect the pre-embedded fixing of the straight threaded sleeves 4.

[0032] By adjusting the distance between the straight threaded sleeve 4 and the top surface of the precast wall panel 2, as well as the distance between the mounting hole 34 and the support plate 32, the preset position between the precast floor slab 1 and the precast wall panel 2 can be adjusted. After the straight threaded sleeve 4 is embedded, the setting height of the precast floor slab 1 can also be finely adjusted by adjusting the thickness of the support plate 32 to ensure effective support for the precast floor slab 1.

[0033] Generally, at least two support seats 3 are provided on each of the precast wall panels 2 symmetrically arranged on both sides of the precast floor slab 1 to provide stable support for the precast floor slab 1.

[0034] Preferably, the support plate 32 is provided with two support holes 35, which are symmetrically arranged on both sides of the reinforcing plate 33. Each support hole 35 is threaded with a support bolt 36. The top of the support bolt 36 is in contact with the bottom of the precast floor slab 1. The position of the top of the support bolt 36 can be adjusted by turning the support bolt 36, thereby realizing the leveling operation of the precast floor slab 1.

[0035] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
