Abstract
Description
Technical Field
[0001] The utility model relates to a connecting member, in particular to a connecting member for a thermal insulation board and an in-situ concrete system with built-in thermal insulation. Background Art
[0002] The cast-in-place shear walls are divided into external cast-in-place shear walls and internal cast-in-place shear walls. Generally, thermal insulation materials need to be laid on the external cast-in-place shear walls to resist the overheated or overcooled external environment. In the early days, the thermal insulation materials were adhesively fixed on the outer surface of the cast-in-place shear wall, and then an external facade coating was applied on the outer surface of the thermal insulation materials. With the passage of time, there is a risk of peeling off of both the external coating and the thermal insulation materials, so there will be safety risks.
[0003] To solve this problem, there is a new construction process at present. An in-situ concrete shear wall with self-thermal insulation is formed by using a composite thermal insulation board with an internal wire mesh as the thermal insulation board, the wire mesh is arranged on the outer side of the thermal insulation board, and a steel reinforcement cage is arranged on the inner side of the thermal insulation board, and concrete is poured on both sides of the thermal insulation board at the same time. The function of the wire mesh is to effectively disperse the stress on the surface of the concrete base layer and play a good anti-cracking effect.
[0004] However, in the actual construction process, due to the lack of stable positioning of the thermal insulation board and the wire mesh, problems such as the floating of the thermal insulation board and the fitting of the wire mesh and the thermal insulation board are likely to occur. The material of the thermal insulation board is similar to that of the foam board and has a low density. Therefore, if the thermal insulation board is not effectively fixed during the pouring process, the thermal insulation board will float to a certain extent. After the thermal insulation board floats, the problem of cold and heat bridges at the bottom will occur; at the same time, the thermal insulation board contains brominated flame retardants that can corrode the wire mesh, and the long-term contact between the wire mesh and the thermal insulation board will cause the wire mesh at the contact part to be corroded. Summary of the Invention
[0005] The utility model provides a connecting member for a thermal insulation board and an in-situ concrete system with built-in thermal insulation, and solves the problems of cold and heat bridges and metal corrosion caused by the lack of effective positioning of the thermal insulation board and the steel wire mesh in the existing cast-in-place shear wall.
[0006] The above technical problems of the present utility model are mainly solved by the following technical solutions: A thermal insulation board connecting member includes a metal anchor rod and a pipe sleeve sleeved outside the metal anchor rod. The inner section of the metal anchor rod is not wrapped by the pipe sleeve. An inner broken-bridge waterproof cap is sleeved on the inner end of the metal anchor rod. A relatively fixed wire mesh positioning piece is provided at the outer end of the pipe sleeve. A wire mesh clamping groove is provided on the outer side surface of the wire mesh positioning piece. A bending part that abuts against and limits the outer end of the pipe sleeve is provided at the outer end of the metal anchor rod. An outer broken-bridge waterproof cap is covered on the bending part. A relatively fixed fixed clamping disc is provided in the middle of the pipe sleeve. An adjustment section is provided between the inner end of the pipe sleeve and the fixed clamping disc. A number of one-way locking teeth or external threads are provided on the outer wall of the adjustment section. A movable clamping disc that forms one-way limitation with the one-way locking teeth or is screwed with the external threads is sleeved on the adjustment section. The pipe sleeve, the broken-bridge waterproof cap, the wire mesh positioning piece, the outer broken-bridge waterproof cap, the fixed clamping disc and the movable clamping disc are all made of plastic materials.
[0007] The present utility model is used to connect and position the wire mesh, the thermal insulation board and the steel reinforcement cage. Generally, 6 to 8 of the present utility models need to be installed and fixed on each square meter of the steel reinforcement cage. The part of the metal anchor rod that is not covered by the pipe sleeve is used for horizontal fixed connection with the steel reinforcement cage, generally by wire binding or welding. During in-situ construction, the two ends of the metal anchor rod abut against the casting templates on both sides of the shear wall, which can assist in positioning the distance between the two templates and improve the flatness of the templates. The pipe sleeve sleeved on the metal anchor rod needs to penetrate the thermal insulation board. The function of the pipe sleeve is to isolate the thermal insulation board from the metal anchor rod. It can not only ensure that the connecting rod will not be corroded by the bromine-based flame retardant contained in the thermal insulation board, effectively ensuring the durability and safety of the composite wall, but also avoid direct contact between the metal anchor rod and the cement outside the thermal insulation board, which can effectively prevent the metal anchor rod from becoming a cold and heat bridge and improve the overall thermal insulation effect. The pipe sleeve also has the function of fixing the fixed clamping disc and the movable clamping disc. The movable clamping disc is sleeved on the adjustment section and can move unidirectionally towards the fixed clamping disc. The fixed clamping disc and the movable clamping disc are used to clamp and fix the thermal insulation board. The wire mesh clamping groove on the wire mesh positioning piece is used to clamp the wire mesh. The two ends of the metal anchor rod are provided with broken-bridge waterproof caps. Through this broken-bridge design, the heat exchange of the metal anchor rod can be effectively reduced, thereby improving the thermal insulation performance of the composite wall. At the same time, it also plays a role in protecting the top end of the metal anchor rod, has a certain waterproof effect, avoids the entry of rainwater between the metal anchor rod and the concrete after cold and heat freeze-thaw changes, and prevents the rainwater from corroding it.
[0008] Further, an outer pipe sleeve is sleeved on the pipe sleeve, the wire mesh positioning piece is fixed on the outer pipe sleeve, and a limiting part for preventing the outer pipe sleeve from coming off is arranged at the outer end of the pipe sleeve; a plurality of limiting plates are arranged on one side of the movable clamping disc facing away from the fixed clamping disc. When the metal anchor rod in the present utility model is fixed to the steel reinforcement cage, the bent part on the metal anchor rod will abut against the outside of the limiting part, the limiting part abuts against the outer end of the outer pipe sleeve, the inner end of the outer pipe sleeve abuts against the fixed clamping disc, the fixed clamping disc abuts against the heat preservation board, the heat preservation board abuts against the movable clamping disc, and the limiting plates on the movable clamping disc abut against the steel reinforcement cage. To sum up, the present utility model can simplify the injection mold design of plastic parts through the above technical solutions, and at the same time, each accessory can relatively fix the wire mesh, the heat preservation board and the steel reinforcement cage through a simple assembly method, and ensure that the three are spaced apart from each other.
[0009] The present utility model also provides an in-situ cast concrete system with built-in heat preservation, including concrete, a steel reinforcement cage, a heat preservation board and a wire mesh. It is characterized in that: it further includes a connecting member, the connecting member is the above-mentioned heat preservation board connecting member, the inner section of the metal anchor rod on the connecting member is fixedly connected to the steel reinforcement cage, the heat preservation board is fixed between the movable clamping disc and the fixed clamping disc, and the wire mesh is fixed in the wire mesh clamping groove. Since the above-mentioned connecting member has the above-mentioned technical effects, the in-situ cast concrete with built-in heat preservation having this connecting member also has the same technical effects.
[0010] Therefore, the present utility model has the following characteristics compared with the prior art: 1. The present utility model can be used to fix the steel reinforcement cage, the heat preservation board and the wire mesh in the in-situ cast concrete construction with built-in heat preservation board, avoid the problem of the heat preservation board floating up during pouring resulting in a cold bridge at the bottom, and at the same time can ensure that the wire mesh will not be corroded by the brominated flame retardant contained in the heat preservation board, effectively ensuring the durability and safety of the composite wall; 2.
