[0001] The utility model relates to the field of light-transmitting plain concrete wall construction, in particular to a reusable light guide tube pre-embedded component. Background Art

[0002] The construction of light-transmitting fair-faced concrete walls is an inevitable construction process in complex and diverse building structure projects. In order to make it easier to achieve the expected light-transmitting effect and improve the quality of the finished product, the current method is to pre-embed the conduit sleeve in the fair-faced concrete wall, and then insert the light guide pipe into the light guide pipe sleeve to achieve the construction of the light-transmitting fair-faced concrete wall.

[0003] For example, Chinese patent CN 218213576 U discloses a light guide pre-embedded device for a plain concrete exterior wall, in which a sleeve is pre-embedded in the plain concrete exterior wall, and a fixed light guide is then inserted therein. Although this type of light guide sleeve pre-embedded facilitates the construction of the light guide, the light guide sleeve is fixed in the plain concrete wall and cannot be disassembled. During the construction process, the sleeve part protruding from the wall needs to be cut.

[0004] This type of structure has the following problems: the surface of the wall cut by the light guide sleeve is uneven, and the end face of the cut light guide sleeve needs to be polished and smooth; the embedded parts of the light guide steel sleeve are expensive, the sleeve processing cost is high, the processing is difficult, and it cannot be disassembled and therefore cannot be reused; when applied to curved walls, it cannot adapt to the curvature of the wall, and the protruding structural surface needs to be cut later. The process is cumbersome and also affects the quality of the finished structure. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The front, back, left, right, top, bottom, inside, outside, etc. involved in the utility model are limited to the description of the structural orientation according to the drawings and do not constitute a limitation on the structure.

[0021] See also Figures 1 to 6 As shown, an embodiment of the utility model provides a reusable light guide tube embedded component, including a steel bar positioning ring 1; a water-stop rubber sleeve 2; a light guide tube sleeve 3; a plain concrete wall 4; a light guide tube 5; and a silicone sealant 6.

[0022] The light guide tube sleeve 3 is a hollow tubular structure with two ends connected, and is made of hard PVC. A groove 31 is provided at one end of the light guide tube sleeve 3, and the outer diameter of the end provided with the groove is larger than the outer diameter of the light guide tube sleeve body.

[0023] At least two waterproof rubber sleeves 2 are sleeved at intervals along the length direction of the light guide tube sleeve 3 on the outer circumference, and a steel bar positioning ring 1 is arranged on the outer circumference of the waterproof rubber sleeve 2. The steel bar positioning ring 1 fastens the waterproof rubber sleeve 2 to the outer circumference of the light guide tube sleeve 3. The fastening degree of the steel bar positioning ring 1 should ensure that after the light guide tube sleeve 3 is buried in the plain concrete wall 4, it can be pulled out of the plain concrete wall and separated from the waterproof rubber sleeve 2. The width of the steel bar positioning ring 1 is smaller than the width of the waterproof rubber sleeve 2. By sleeved with the waterproof rubber sleeve 2 and the steel bar positioning ring 1, it is convenient to fix the light guide tube sleeve 3 when the light guide tube sleeve 3 is pre-buried in the plain concrete wall 4. At the same time, it is prevented that the steel bar positioning ring 1 scratches the light guide tube sleeve 3 when the light guide tube sleeve 3 is pulled out from the plain concrete wall 4.

[0024] The length of the light guide sleeve 3 is greater than the thickness of the exposed concrete wall 4. Preferably, the length of the light guide sleeve 3 is equal to the thickness of the exposed concrete wall + 50 mm. The inner diameter of the light guide sleeve 3 is greater than the outer diameter of the light guide 5. Preferably, the inner diameter of the light guide sleeve 3 is equal to the outer diameter of the light guide 5 + 20 mm.

[0025] During construction, the light guide tube sleeve 3 with the steel bar positioning ring 1 and the waterproof rubber sleeve 2 is set in the clear water concrete wall 4, and the steel bar positioning ring 1 is welded and fixed to the wall steel bar of the clear water concrete wall 4 to achieve the fixation of the light guide tube sleeve 3. After fixation, it is satisfied that: the end face of the light guide tube sleeve 3 with the tongue and groove is located outside the clear water concrete wall 4, protruding a certain distance from the wall surface of the clear water concrete wall 4, the tongue and groove part of the light guide tube sleeve 3 is located inside the clear water concrete wall 4, and the other part is located outside the clear water concrete wall 4, and the other end of the light guide tube sleeve 3 is flush with the inner wall surface of the clear water concrete wall 4; the two waterproof rubber sleeves 2 are respectively located in the clear water concrete wall 4, and close to the inner and outer sides of the clear water concrete wall 4. After the fixation is completed, the casting construction of the clear water concrete wall 4 is carried out.

[0026] When the pouring construction of the fair-faced concrete wall 4 is completed and the formwork can be removed, the light guide tube sleeve 3 is removed together with the formwork to form an installation hole for the light guide tube 5 in the fair-faced concrete wall 4. At the same time, a tongue and groove is formed at one end of the installation hole located outside the fair-faced concrete wall 4 through the tongue and groove of the light guide tube sleeve. The inner diameter of the tongue and groove at the installation hole is larger than the inner diameter of the installation hole outside the tongue and groove part, that is, a limiting step is formed at one end of the tongue and groove of the installation hole to limit the installation position of the light guide tube when it is installed.

[0027] In order to facilitate the extraction of the light guide tube sleeve 3 from the fair-faced concrete wall 4, a release agent is applied to the outer circumference of the light guide tube sleeve 3 before the light guide tube sleeve 3 is fixed to the wall reinforcement.

[0028] When the light guide tube sleeve 3 is pulled out, the waterproof rubber sleeve 2 and the positioning steel bar ring 1 remain in the installation hole respectively, and the inner side surface of the waterproof rubber sleeve 2 is flush with the inner wall of the installation hole.

[0029] Installation of the light guide 5: First, waterproof rubber sleeves are arranged at intervals along the length direction on the outer circumference of the light guide 5, and then the light guide 5 is inserted into the installation hole from one end of the installation hole with a tongue and groove. The waterproof rubber sleeve is located inside the installation hole of the exposed concrete wall 4. The waterproof rubber sleeve makes the light guide 5 fit tightly with the inner wall of the installation hole to prevent leakage. The tongue and groove of the installation hole form a penetration limit for the light guide 5, and the gap between the exposed concrete wall 4 and the light guide 5 is sealed with silicone sealant 6.

[0030] The present invention adopts a technical solution of pre-embedding a light guide tube sleeve 3 with a tongue and groove into a plain concrete wall 4, then pulling the light guide tube sleeve 3 out of the plain concrete wall, and then installing a light guide tube 5. Compared with the prior art, the wall surface is flat after the light guide tube sleeve is disassembled and no additional repair is required. The light guide tube sleeve 3 with a tongue and groove can be reused, which is energy-saving and environmentally friendly. It is also suitable for light guide tubes of various specifications and sizes, reducing construction costs and construction period, and facilitating the promotion of light-transmitting plain concrete wall construction.
