Description

Technical Field

[0001] This utility model relates to the technical field of building insulation, and in particular to a passive insulation construction structure for outdoor floor slabs. Background Technology

[0002] Passive buildings mainly refer to building energy conservation methods that do not rely on building equipment that consumes energy themselves, but achieve energy conservation entirely through the design of the building's spatial form, envelope, building materials and construction.

[0003] In building construction, to achieve energy-saving effects, many buildings require insulation of the exterior floor slabs in addition to exterior wall insulation. Currently, the common construction method is to lay insulation boards under the concrete floor slab after the concrete is poured, then install fixing nails according to the insulation structure system on the insulation boards, lay mesh cloth, and apply finishing mortar. This method has quality problems such as poor insulation tightness and unstable fixing nails. Furthermore, it involves upward-facing construction, which is difficult and inefficient.

[0004] To address the aforementioned issues, this application provides a passive thermal insulation construction structure for outdoor floor slabs, resolving the quality risks associated with traditional thermal insulation installations, such as large-area detachment due to insecure fixing nails. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a passive thermal insulation construction structure for outdoor floor slabs that is simple in structure, low in cost, and easy to operate.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model of an outdoor passive thermal insulation construction structure for floor slabs includes a support frame, a template set on the support frame, an insulation board set on the template, a plastic film laid on the insulation board, and a reinforced concrete floor slab poured on the plastic film.

[0008] The insulation board is connected to the reinforced concrete floor slab via thermal break anchors.

[0009] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the thermal break anchor bolt includes a fixed section located within the insulation board and an anchoring section located within the reinforced concrete floor slab. The anchoring section is located above the plastic film, and the fixed section is located below the plastic film. The anchoring section and the fixed section are fixed axially by screws.

[0010] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the anchoring section has a through hole along its axial direction, and the upper part of the fixing section has a threaded hole coaxial with the through hole, and the screw is threadedly engaged with the threaded hole.

[0011] Furthermore, in this utility model of a passive thermal insulation construction structure for outdoor floor slabs, the inner wall of the perforation is provided with an internal thread that mates with a screw.

[0012] Furthermore, in this utility model of a passive thermal insulation construction structure for outdoor floor slabs, the thermal break anchor bolts are made of plastic.

[0013] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the fixing section is a solid structure and the anchoring section is a hollow structure.

[0014] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the lower end of the anchoring section is provided with a stepped surface with a diameter larger than that of the anchoring section, and the stepped surface presses on the plastic film.

[0015] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the upper end of the anchoring section is provided with a receiving groove with a diameter larger than the perforation diameter to accommodate the end of the screw.

[0016] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the side of the anchoring section is formed with through holes for reinforcing bars, through which the reinforcing bars of the reinforced concrete floor slab pass.

[0017] In this utility model of passive thermal insulation construction structure for outdoor floor slabs, the end of the thermal break anchor bolt is provided with an enlarged head that abuts against the outer end face of the insulation board.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. This application achieves the simultaneous casting of insulation boards and reinforced concrete floor slabs through the above-mentioned structure. A layer of plastic film is laid on the insulation board to prevent the insulation board from absorbing moisture from the cast-in-place concrete. After the plastic film is laid, the reinforced concrete floor slab is poured. Through the above-mentioned integrated construction, the quality hazard of large-area detachment of insulation boards due to insecure anchor bolt fixation is effectively solved. Compared with the conventional method of constructing the structure first and then the insulation, it has the advantages of convenient construction, high quality, and shortened construction period, while meeting the requirements of passive building construction.

[0020] 2. By setting segmented anchor bolts, the anchor bolts are prevented from penetrating the plastic film, which would cause concrete moisture to seep into the insulation board, thus ensuring the insulation effect of the insulation board.

[0021] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0028] like Figures 1-4 As shown, this utility model discloses a passive thermal insulation construction structure for outdoor floor slabs, including a support frame 1, a template 2 set on the support frame 1, an insulation board 3 set on the template 2, a plastic film 4 laid on the insulation board 3, and a reinforced concrete floor slab 5 poured on the plastic film 4. The insulation board 3 is connected to the reinforced concrete floor slab 5 through thermal break anchor bolts 6.

[0029] This application involves supporting the formwork 2 with a support frame 1, inserting thermal break anchor bolts 6 into the insulation board 3 and laying it flat on the formwork 2, and then laying a layer of plastic film 4 on the insulation board 3 to prevent the insulation board 3 from absorbing moisture from the cast-in-place concrete. After the plastic film 4 is laid, the reinforced concrete floor slab 5 is poured. Through the above integrated construction, the quality hazard of large-area detachment of the insulation board 3 due to the insecure fixing of the anchor bolts is effectively solved. Compared with the conventional method of constructing the structure first and then the insulation, it has the advantages of convenient construction, high quality, and shortened construction period, while meeting the requirements of passive building construction.

[0030] The support frame 1 is the existing support structure of the template 2, which will not be described again in this application. The insulation board 3 is a composite rock wool board in this embodiment.

[0031] The thermal break anchor 6 includes a fixed section 6.1 located within the insulation board 3 and an anchoring section 6.2 located within the reinforced concrete floor slab 5. The anchoring section 6.2 is located above the plastic film 4, and the fixed section 6.1 is located below the plastic film 4. The anchoring section 6.2 and the fixed section 6.1 are fixed axially by screws 6.3.

[0032] The fixed section 6.1, at its end furthest from the anchoring section 6.2, has an enlarged head 6.4 that abuts against the outer end face of the insulation board 3. Both the anchoring section 6.2 and the fixed section 6.1 are made of plastic and serve as heat insulation. The fixed section 6.1 is a solid structure, while the anchoring section 6.2 is a hollow structure. Specifically, the anchoring section 6.2 has a through hole along its axial direction, and the upper part of the fixed section 6.1 has a threaded hole 6.5 coaxial with the through hole. A screw 6.3 engages with the threaded hole 6.5 to connect the fixed section 6.1 and the anchoring section 6.2. In addition, there is an internal thread on the inner wall of the through hole that engages with the screw 6.3, increasing the stability of the connection between the anchoring section 6.2 and the fixed section 6.1 and strengthening the anchoring ability.

[0033] The upper end face of the anchoring section 6.2 is provided with a receiving groove 6.6 with a diameter larger than the diameter of the perforation. The upper end of the screw 6.3 is accommodated in the receiving groove 6.6. The lower end of the anchoring section 6.2 is provided with a stepped surface 6.7 with a diameter larger than the diameter of the anchoring section 6.2. The stepped surface 6.7 presses on the plastic film 4. By setting the stepped surface 6.7, the plastic film 4 is pressed below the stepped surface 6.7, which can ensure that after the plastic film 4 is penetrated by the screw 6.3, concrete moisture seeps into the insulation board 3, causing a decrease in the insulation effect.

[0034] In another embodiment of this application, a through-hole 7 is formed on the side of the anchoring section 6.2. The reinforcing bars of the reinforced concrete floor slab 5 are passed through the through-hole to connect the thermal break anchor bolt 6 to the reinforcing bars. This makes the anchor bolt more anchoring, ensures the installation quality of the insulation board 3, and avoids the problem of the insulation board 3 falling off.

[0035] The installation steps are as follows:

[0036] Set up a support frame 1, lay template 2 on the support frame 1, pass thermal break anchor bolt 6 through insulation board 3, lay insulation board 3, lay plastic film 4 after completion, install anchor section 6.2, and connect anchor section 6.2 to fixed section 6.1 with screw 6.3, tie floor slab reinforcement, pass reinforcement at corresponding positions through reinforcement holes, connect thermal break anchor bolt 6 to reinforcement, and pour concrete to form reinforced concrete floor slab 5.

[0037] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
