Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a load-bearing floor deformation joint anchoring structure. Background Art

[0002] Generally, if the plane dimensions of a building are too long, the load-bearing surface will be repeatedly squeezed for a long time, resulting in fatigue deformation. At the same time, due to seasonal thermal expansion and contraction, excessive stress may be generated in the structure, causing internal damage to the building. In order to avoid this problem, gaps (also called deformation joints or expansion joints) need to be reserved at certain intervals along the length of the building during the construction process to release excess stress.

[0003] As a common construction method of floor expansion joints, the deformation joints need to be anchored together. Generally, guidance and construction basis can be found in relevant architectural drawings and standards such as 14J936 design drawing collection, which is of guiding significance for typical building structures, but it is more difficult to handle for high working environment requirements (waterproofing, heat preservation and fire prevention), special-shaped building structures (including steel structures), large width and large span expansion joints, heavy loads and frequent regular and irregular loads. Common and simple methods cannot simultaneously meet the purposes of high strength, stiffness and yield stress limit as well as reasonable drainage, heat preservation, energy saving and fire prevention.

[0004] To this end, the applicant further proposed an improvement plan based on the original plan for the purpose of saving maintenance costs and avoiding repeated repairs. Utility Model Content

[0010] A water stop belt, both ends of which are anchored in the load-bearing assembly and are located below the slide bar, and a gutter is provided on the outside of the water stop belt to drain all dripping water seeping from the water stop belt to the end of the gutter;

[0011] The heat-insulating fireproof component is located below the gutter, and is connected to a pair of symmetrically arranged steel beams on both sides. The steel beams are fixedly arranged at the lower end of the expansion joint.

[0012] Furthermore, the load-bearing component includes:

[0013] The bottom of the cover plate abuts against the top layer of the floor slab and a rubber pad is provided at the contact position;

[0014] The composite base is located at the bottom of the cover plate, and the top of the composite base is fixed with the half-open buckle by a fastener, and the half-open buckle is against the bottom of the cover plate.

[0015] Furthermore, the composite base includes a polymer waterproof mortar base and an aluminum alloy base, and the polymer waterproof mortar base and the aluminum alloy base are arranged alternately and located on both sides of the expansion joint to bear the force of the cover plate;

[0016] The aluminum alloy base is provided with screw holes for fixing the cover plate.

It can fully release the stress in the structure and reduce fatigue damage. It is effective under heavy loads, overloads and frequent load conditions.

DETAILED DESCRIPTION

[0034] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to Figure 1-Figure 5 The utility model discloses a load-bearing floor deformation joint anchoring structure, which is used for connecting the expansion joints between floor slabs. The anchoring structure is now described.

[0036] like Figure 1 The expansion joint anchoring structure disclosed in the technical solution mainly includes a load-bearing component 1, a gutter 3 and a thermal insulation and fireproof component 5. Among them, a sliding rod 6 is installed in the middle of the load-bearing component 1, and the sliding rod 6 is suitable for shifting left and right along the expansion joint, and the sliding rod 6 is located between the expansion joints of the floor.

[0037] In the prior art, the construction method of the deformation joint mainly uses the sliding rod that moves up and down to bear the heavy load, making it the main component for releasing stress. Secondly, it can also rely on the elastic modulus of the material itself to release fatigue stress. Different from this, according to the fourth strength theory of mechanics (also known as the distortion energy theory, its theoretical statement is that the distortion energy density causes the material to yield), and after analysis of the Soliworks Vomise stress model, in fact, under the action of vertical heavy loads, the sliding rod that moves left and right is more prominent in stiffness, fatigue strength and overall equivalent strength than the sliding rod that moves up and down, especially under irregular stress conditions, its life is longer.

[0038] Therefore, it is obvious that the load-bearing component 1 with the slide bar 6 in the middle has a longer service life, and the load-bearing component 1 is embedded in the upper end of the expansion joint, so that the horizontally sliding slide bar 6 is used to transmit the force and strain from the load-bearing component 1, and the slide bar 6 is fixed on the half-open buckle 7 on both sides of the expansion joint, and the load and strain are released through the relative movement between the half-open buckle 7 and the slide bar 6. On the other hand, a water stop 2 is anchored in the load-bearing component 1, and the water stop 2 is located below the slide bar 6, and a gutter 3 is arranged on the outside of the water stop 2 to drain all the dripping water seeping from the water stop 2 to the end of the gutter 3. In addition, in order to achieve a fire prevention effect, a heat-insulating fireproof component 5 is also arranged below the gutter 3, and the two sides of the heat-insulating fireproof component 5 are connected to a pair of symmetrically arranged steel beams 4, and the steel beams 4 are fixedly arranged at the lower end of the expansion joint.

[0039] In this embodiment, if Figure 2 The load-bearing component 1 includes a cover plate 11 and a composite base 13, wherein the bottom of the cover plate 11 is against the top layer of the floor slab, and a rubber pad 12 is provided at the contact position, which can play a certain buffering role and also reduce water seepage along the gap. The bottom of the cover plate 11 is fastened to the composite base 13 by bolts, and the top of the composite base 13 is fixed with a half-open buckle 7 by a fastener 14, and the half-open buckle 7 is against the bottom of the cover plate 11. The half-open buckle 7 is opposite to the left and right, and a slide bar 6 is slidably provided at the opening so that the slide bar 6 can slide left and right. In this embodiment, the cover plate 11, the slide bar 6 and the half-open buckle 7 are all galvanized steel.

[0040] Based on the previous embodiment, Figure 5 The composite base 13 includes a polymer waterproof mortar base 131 and an aluminum alloy base 132. The polymer waterproof mortar base 131 and the aluminum alloy base 132 are arranged alternately and located on both sides of the expansion joint to bear the force of the cover plate 11. Among them, the polymer waterproof mortar base 131 has a low cost and good compressive resistance, and the aluminum alloy base 132 has better toughness but is easily deformed by pressure. Therefore, screw holes 133 can be set on the aluminum alloy base 132 to fix the cover plate 11, and combined with the waterproof mortar base 131, it plays the effect of supporting the cover plate 11.

[0041] In some embodiments, Figure 4In order to prevent water seepage from causing adverse effects on the floor, in addition to arranging a waterstop strip 2 at the bottom of the expansion joint, a gutter 3 is also provided on the outside of the expansion joint, wherein the gutter 3 includes a groove 31 and a bracket 33, and a channel for diverting water downward is provided at the end of the groove 31, and the length direction of the groove 31 forms an acute angle with the gravity direction, and a vertical downpipe is provided at the end of the groove 31 to drain water to the ground. In other words, the groove 31 itself has a certain slope to facilitate the outflow of seepage water, and the upper end of the groove 31 is clamped and fixed by a galvanized flat steel strip 34, and the galvanized flat steel strip 34 is fixed to the lower end of the expansion joint by an expansion screw 32 to prevent the galvanized flat steel strip 34 from falling off, and a bracket 33 is provided at the bottom of the groove 31, and the two ends of the bracket 33 are fixedly connected to a pair of steel beams 4, and the upper end is connected to the groove 31.

[0042] On the basis of the previous embodiment, a further improvement is proposed. The bracket 33 is arched and uses elastic force to lift the groove 31 upward, thereby reducing the weight of the bracket 33 and achieving the effect of saving costs.

[0043] In some embodiments, Figure 3 The bottom of the bracket 33 is provided with a heat-insulating fireproof component 5, wherein the heat-insulating fireproof component 5 comprises a heat-insulating rock wool caulking 51 and a galvanized steel plate 52, the galvanized steel plate 52 is attached to the outside of the heat-insulating rock wool caulking 51, and the heat-insulating rock wool caulking 51 is arranged below the gutter 3. Since the deformation joints or expansion joints of the general floor are wide, it is impossible to set the heat-insulating fireproof cotton board, and the galvanized steel plate 52 is stuck at the steel beam groove of the steel beam 4 on both sides of the expansion joint, which can effectively solve the installation problem and achieve the effect of energy saving, noise reduction and fire prevention.

[0044] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
